Use of wood stoves and risk of cancers of the upper aero-digestive tract: a case-control study. (1/1149)

BACKGROUND: Incidence rates for cancers of the upper aero-digestive tract in Southern Brazil are among the highest in the world. A case-control study was designed to identify the main risk factors for carcinomas of mouth, pharynx, and larynx in the region. We tested the hypothesis of whether use of wood stoves is associated with these cancers. METHODS: Information on known and potential risk factors was obtained from interviews with 784 cases and 1568 non-cancer controls. We estimated the effect of use of wood stove by conditional logistic regression, with adjustment for smoking, alcohol consumption and for other sociodemographic and dietary variables chosen as empirical confounders based on a change-in-estimate criterion. RESULTS: After extensive adjustment for all the empirical confounders the odds ratio (OR) for all upper aero-digestive tract cancers was 2.68 (95% confidence interval [CI] : 2.2-3.3). Increased risks were also seen in site-specific analyses for mouth (OR = 2.73; 95% CI: 1.8-4.2), pharyngeal (OR = 3.82; 95% CI: 2.0-7.4), and laryngeal carcinomas (OR = 2.34; 95% CI: 1.2-4.7). Significant risk elevations remained for each of the three anatomic sites and for all sites combined even after we purposefully biased the analyses towards the null hypothesis by adjusting the effect of wood stove use only for positive empirical confounders. CONCLUSIONS: The association of use of wood stoves with cancers of the upper aero-digestive tract is genuine and unlikely to result from insufficient control of confounding. Due to its high prevalence, use of wood stoves may be linked to as many as 30% of all cancers occurring in the region.  (+info)

Health status of Persian Gulf War veterans: self-reported symptoms, environmental exposures and the effect of stress. (2/1149)

BACKGROUND: Most US troops returned home from the Persian Gulf War (PGW) by Spring 1991 and many began reporting increased health symptoms and medical problems soon after. This investigation examines the relationships between several Gulf-service environmental exposures and health symptom reporting, and the role of traumatic psychological stress on the exposure-health symptom relationships. METHODS: Stratified, random samples of two cohorts of PGW veterans, from the New England area (n = 220) and from the New Orleans area (n = 71), were selected from larger cohorts being followed longitudinally since arrival home from the Gulf. A group of PGW-era veterans deployed to Germany (n = 50) served as a comparison group. The study protocol included questionnaires, a neuropsychological test battery, an environmental interview, and psychological diagnostic interviews. This report focuses on self-reported health symptoms and exposures of participants who completed a 52-item health symptom checklist and a checklist of environmental exposures. RESULTS: The prevalence of reported symptoms was greater in both Persian Gulf-deployed cohorts compared to the Germany cohort. Analyses of the body-system symptom scores (BSS), weighted to account for sampling design, and adjusted by age, sex, and education, indicated that Persian Gulf-deployed veterans were more likely to report neurological, pulmonary, gastrointestinal, cardiac, dermatological, musculoskeletal, psychological and neuropsychological system symptoms than Germany veterans. Using a priori hypotheses about the toxicant effects of exposure to specific toxicants, the relationships between self-reported exposures and body-system symptom groupings were examined through multiple regression analyses, controlling for war-zone exposure and post-traumatic stress disorder (PTSD). Self-reported exposures to pesticides, debris from Scuds, chemical and biological warfare (CBW) agents, and smoke from tent heaters each were significantly related to increased reporting of specific predicted BSS groupings. CONCLUSIONS: Veterans deployed to the Persian Gulf have higher self-reported prevalence of health symptoms compared to PGW veterans who were deployed only as far as Germany. Several Gulf-service environmental exposures are associated with increased health symptom reporting involving predicted body-systems, after adjusting for war-zone stressor exposures and PTSD.  (+info)

Effects and interactions of opioids on plasma exudation induced by cigarette smoke in guinea pig bronchi. (3/1149)

The effects of opioids on cigarette smoke-induced plasma exudation were investigated in vivo in the main bronchi of anesthetized guinea pigs, with Evans blue dye as a plasma marker. Acute inhalation of cigarette smoke increased plasma exudation by 216% above air control values. Morphine, 0.1-10 mg/kg but not 30 mg/kg, inhibited the exudation but had no significant effect on substance P-induced exudation. Both 10 and 30 mg/kg of morphine increased exudation in air control animals, an effect inhibited by antihistamines but not by a tachykinin neurokinin type 1-receptor antagonist. Naloxone inhibited all morphine responses. Cigarette smoke-induced plasma exudation was inhibited by a mu-opioid-receptor agonist (DAMGO) but not by agonists at delta (DPDPE)- or kappa (U-50488H)-receptors. None of these agonists affected exudation in air control animals. DPDPE prevented the inhibition by DAMGO of cigarette smoke-induced plasma exudation, and the combination of DAMGO and DPDPE increased exudation in air control animals. Prevention of inhibition and the combination-induced increase were inhibited by antihistamines or the mast cell-stabilizing drug sodium cromoglycate. U-50488H did not alter the response to either DAMGO or DPDPE. We conclude that, in guinea pig main bronchi in vivo, mu-opioid-receptor agonists inhibit cigarette smoke-induced plasma exudation via a prejunctional mechanism. Plasma exudation induced by mu- and delta-receptor interactions is due to endogenous histamine release from mast cells.  (+info)

Air pollution, pollens, and daily admissions for asthma in London 1987-92. (4/1149)

BACKGROUND: A study was undertaken to investigate the relationship between daily hospital admissions for asthma and air pollution in London in 1987-92 and the possible confounding and modifying effects of airborne pollen. METHODS: For all ages together and the age groups 0-14, 15-64 and 65+ years, Poisson regression was used to estimate the relative risk of daily asthma admissions associated with changes in ozone, sulphur dioxide, nitrogen dioxide and particles (black smoke), controlling for time trends, seasonal factors, calendar effects, influenza epidemics, temperature, humidity, and autocorrelation. Independent effects of individual pollutants and interactions with aeroallergens were explored using two pollutant models and models including pollen counts (grass, oak and birch). RESULTS: In all-year analyses ozone was significantly associated with admissions in the 15-64 age group (10 ppb eight hour ozone, 3.93% increase), nitrogen dioxide in the 0-14 and 65+ age groups (10 ppb 24 hour nitrogen dioxide, 1.25% and 2.96%, respectively), sulphur dioxide in the 0-14 age group (10 micrograms/m3 24 hour sulphur dioxide, 1.64%), and black smoke in the 65% age group (10 micrograms/m3 black smoke, 5.60%). Significant seasonal differences were observed for ozone in the 0-14 and 15-64 age groups, and in the 0-14 age group there were negative associations with ozone in the cool season. In general, cumulative lags of up to three days tended to show stronger and more significant effects than single day lags. In two-pollutant models these associations were most robust for ozone and least for nitrogen dioxide. There was no evidence that the associations with air pollutants were due to confounding by any of the pollens, and little evidence of an interaction between pollens and pollution except for synergism of sulphur dioxide and grass pollen in children (p < 0.01). CONCLUSIONS: Ozone, sulphur dioxide, nitrogen dioxide, and particles were all found to have significant associations with daily hospital admissions for asthma, but there was a lack of consistency across the age groups in the specific pollutant. These associations were not explained by confounding by airborne pollens nor was there convincing evidence that the effects of air pollutants and airborne pollens interact in causing hospital admissions for asthma.  (+info)

Toxicity of combustion products from burning polymers: development and evaluation of methods. (5/1149)

Laboratory and room-scale experiments were conducted with natural and synthetic polymers: cotton, paper, wood, wool, acetate, acrylic, nylon, and urethane. Smoke and off-gases from single materials were generated in a dual-compartment 110-liter exposure chamber. Multicomponent, composite fuel loads were burned within a 100 m(3) facility subdivided into rooms. In chamber experiments, mortality depended on the amount of material burned, i.e., fuel consumption (FC). Conventional dose (FC)/mortality curves were obtained, and the amount of fuel required to produce 50% mortality (FC(50)) was calculated. With simple flame ignition, cotton was the only material that produced smoke concentrations lethal to rats; FC(50) values for cotton ranged from 2 g to 9 g, depending on the configuration of the cotton sample burned. When supplemental conductive heat was added to flame ignition, the following FC(50) values were obtained; nylon, 7 g; acrylic, 8 g; newsprint, 9 g; cotton, 10 g; and wood, 11 g. Mortality resulting from any given material depended upon the specific conditions employed for its thermal decomposition. Toxicity of off-gasses from pyrolysis of phosphorus-containing trimethylol propane-polyurethane foams was markedly decreased by addition of a flame ignition source. Further studies are needed to determine the possible relevance of single-material laboratory scale smoke toxicity experiments. Room-scale burns were conducted to assess the relative contributions of single materials to toxicity of smoke produced by a multicomponent self-perpetuating fire. Preliminary results suggest that this approach permits a realistic evaluation of the contribution of single materials to the toxicity of smoke from residential fires.  (+info)

Combined effect of cigarette smoke and mineral fibers on the gene expression of cytokine mRNA. (6/1149)

To investigate which parameters are stimulated by mineral fibers and whether cigarette smoke enhanced a fiber-induced response, we examined the level of cytokine mRNA from alveolar macrophages (AMs) and lungs of rats exposed to mineral fibers and cigarette smoke in vivo. Male Wistar rats were given a single intratracheal instillation of 2 mg of Union Internationale Contre le Cancer chrysotile or refractory ceramic fiber (RF1). The animals then inhaled a side stream of smoke 5 days per week for 4 weeks. The expression of manganese superoxide dismutase, inducible nitric oxide synthase (iNOS), basic fibroblast growth factor (bFGF), interleukin-1[alpha] (IL-1[alpha]), interleukin-6 (IL-6), and tumor necrosis factor-[alpha] (TNF[alpha]) mRNA from lipopolysaccharide-stimulated AMs and lungs of rats exposed to mineral fibers and/or cigarette smoke were assessed using semiquantitative reverse-transcriptase polymerase chain reaction. Exposure only to cigarette smoke increased in IL-1[alpha] mRNA levels in AMs. Chrysotile stimulated the expression of IL-1[alpha], TNF[alpha], and IL-6 in AMs, and the expression of bFGF in lungs. RF1 resulted in increased expression of IL-1[alpha] and TNF[alpha] in AMs. Cigarette smoke stimulated the gene expression of iNOS in AMs and IL-6 and bFGF in lungs treated with chrysotile; IL-1[alpha] in AMs and bFGF in lungs did the same in lungs with RF1. Among these cytokines, message levels of IL-1[alpha], iNOS, and bFGF were increased in rats stimulated with mineral fibers, and the stimulating effects of mineral fibers were enhanced by cigarette smoke. Therefore, IL-1[alpha], iNOS, and bFGF would be the possible parameters of the lung remodeling induced by mineral fibers.  (+info)

Early alterations of lung injury following acute smoke exposure and 21-aminosteroid treatment. (7/1149)

In a simulated fire-related smoke exposure protocol, New Zealand white rabbits were utilized to investigate the potential effects of the 21-aminosteroid (lazaroid) analog U75412E on the early events of acute lung injury. Inhalation of a total of 1.6 mg/kg U75412E aerosolized at a rate of 1.53 mg/min at 0.5 hr after smoke exposure significantly attenuated the extent of lung injury at 1 hr, as evidenced by decreased bronchoalveolar lavage (BAL) concentration of total protein, 6-keto-prostaglandin F1-alpha, and blood gas defect. Histopathologic examination demonstrated that the lazaroid significantly attenuated smoke-induced lung injury as evidenced by a decrease in wet lung/body weight ratio, necrosis, and sloughing of airway epithelial cells. Electron microscopy showed that the lazaroid decreased smoke-induced interstitial edema and the vacuolization of alveolar type II epithelium (21.6 +/- 9.7 vs 8.5 +/- 3.6 vacuoled blebs/cell, smoke only vs smoke + lazaroid). However, U75412E did not attenuate smoke-induced changes in BAL concentration of tumor necrosis factor-alpha, total cell count, and granulocyte percentage. These observations suggest that U75412E may exert its action through cooperative mechanisms, such as the modulation of arachidonic acid metabolism, in addition to its characterized antioxidative effects.  (+info)

Chemoprevention of tobacco smoke-induced lung tumors in A/J strain mice with dietary myo-inositol and dexamethasone. (8/1149)

Male A/J strain mice were fed AIN-76A diet supplemented with myo-inositol/dexamethasone (10 g and 0.5 mg/kg diet) or acetylsalicylic acid (300 mg/kg) and exposed for 5 months to a mixture of sidestream and mainstream cigarette smoke at a concentration of 132 mg total suspended particulates/m3. After tobacco smoke exposure, they were allowed to recover for another 4 months in filtered air. In the animals fed AIN-75A diet alone or acetylsalicylic acid, the average number of tumors/lung was 2.1, whereas in the animals given the myo-inositol/dexamethasone diet, the average lung tumor multiplicity was 1.0 (P < 0.05). In animals exposed to filtered air, lung tumor multiplicities were 0.6 for animals fed AIN-76A or myo-inositol/dexamethasone and 1.2 for animals fed acetylsalicylic acid. It was concluded that the combination of myo-inositol and dexamethasone constitutes an effective chemopreventive regimen against tobacco smoke-induced lung tumorigenesis.  (+info)

Inflammation plays a key role in the atherosclerotic process. As part of a study on the influence of cigarette mainstream smoke (ms) in combination with high-fat diet on the development of atherosclerosis, we investigated the inflammatory response and histopathological alterations in lungs from Apolipoprotein E-deficient (ApoE -/-) mice, a classic model for atherosclerosis. Male ApoE -/- mice were whole-body exposed for 12 months (6 h/d, 5 d/wk) to diluted MS at total particulate matter (TPM) concentrations of 100 and 200 μg/l or to filtered fresh air. Each exposure group was fed either a chow diet or a milk-fat-enriched diet. Bronchoalveolar lavage (BAL) was performed and inflammatory cells were quantified in BAL fluid (BALF); lungs were evaluated histopathologically. Mice exposed to 100 μg TPM/l MS showed no statistically significant inflammatory and epithelial changes in the lung. Mice exposed to 200 μg TPM/l MS showed statistically significant inflammatory changes, i.e., a constant ...

Although cigarette smoke (CS) exposure and particulate inhalation are known to alter mucociliary clearance, little is known about how CS and nanoparticles (NPs) modify cilia beating at the cytoskeletal infrastructure, or axonemal, level. Methods: We used a cell-free model to introduce cigarette smoke extract (CSE) and NPs with variant size and surface chemistry to isolated axonemes and measured changes in ciliary motility. We hypothesized that CSE would alter cilia beating and that alterations in ciliary beat ...
Tobacco smoke particles on the surface of a cigarette filter fibre, coloured scanning electron micrograph (SEM).The pollutants generated by the cigarette arise from the chemical process of burning organic matter or the combustion of tobacco and paper. Tobacco smoke particulate matter consists of millions of tiny particles of diverse chemical composition. Particulate matter from tobacco smoke includes many small particulates of different size that reflect light (tobacco smoke is easily seen by the naked eye). Gases are also emitted by the cigarette such as benzene and carbon monoxide. Particles smaller than 2.5 micrometres are major components of cigarette smoke and can enter deep into the lung where they can cause serious health problems, including cancer.

Cigarette smoking is a common and lethal worldwide habit, with considerable mortality stemming from its deleterious effects on heart function. While current theories posit altered blood lipids and fibrinogen metabolism as likely mediators, none have explored the role of the sphingolipid ceramide in exacerbating heart function with smoke exposure. Ceramide production is a consequence of cigarette smoke in the lung, and considering ceramides harmful effects on mitochondrial function, we sought to elucidate the role of ceramide in mediating smoke-induced altered heart mitochondrial respiration. Lung cells were exposed to cigarette smoke extract and heart cells were exposed to the lung-cell conditioned medium. Adult male mice were exposed sidestream cigarette smoke for 8 weeks with dietary intervention and ceramide inhibition. Ceramides and heart cell or myocardial mitochondrial respiration were determined. Lung cell cultures revealed a robust response to cigarette smoke extract in both production and

Protocadherin-1 (PCDH1) is a novel susceptibility gene for airway hyperresponsiveness, first identified in families exposed to cigarette smoke and is expressed in bronchial epithelial cells. Here, we asked how mouse Pcdh1 expression is regulated in lung structural cells in vivo under physiological conditions, and in both short-term cigarette smoke exposure models characterized by airway inflammation and hyperresponsiveness and chronic cigarette smoke exposure models. Pcdh1 gene-structure was investigated by Rapid Amplification of cDNA Ends. Pcdh1 mRNA and protein expression was investigated by qRT-PCR, western blotting using isoform-specific antibodies. We observed 87% conservation of the Pcdh1 nucleotide sequence, and 96% conservation of the Pcdh1 protein sequence between men and mice. We identified a novel Pcdh1 isoform encoding only the intracellular signalling motifs. Cigarette smoke exposure for 4 consecutive days markedly reduced Pcdh1 mRNA expression in lung tissue (3 to 4-fold), while ...

Hi Jonah James. The devices which signal the smoke in area are called smoke detectors. And in this modern world where a house, office or commercial area is full of flammable materials it is really necessary to have some detectors who can signal by detecting smoke in the area.. Choice of smoke detectors depends upon many factors, like area where you want to install it, operation of smoke detector etc.. Here I will explain different types of smoke detectors so that you can choose according to your requirement.. Photoelectric smoke detectors: These devices work on the principle of photoelectric beams, when smoke breaks the photoelectric beam of the device then it signals alarm.. Ionization smoke detectors: These devices have small ionization chamber and when smoke particles enter in that chamber it signals alarm. This is very sensitive and so chances of false alarm increases. It is little cheaper.. Air sampling smoke detectors: There is nephelometer in this which detects very small invisible smoke ...
Introduction The Tobacco Control Act requires public disclosure of information about toxic constituents in cigarette smoke. To inform these efforts, we studied public understanding of cigarette smoke constituents.Methods We conducted phone surveys with national probability samples of adolescents (n=1125) and adults (n=5014) and an internet survey with a convenience sample of
In this study, we evaluated the anti-inflammatory effect of PM014 on cigarette smoke induced lung disease in the murine animal model of chronic obstructive pulmonary disease (COPD). Mice were exposed to cigarette smoke (CS) for 2 weeks to induce COPD-like lung inflammation. Two hours prior to cigarette smoke exposure, the treatment group was administered PM014 via an oral injection. To investigate the effects of PM014, we assessed PM014 functions in vivo, including immune cell infiltration, cytokine profiles in bronchoalveolar lavage (BAL) fluid and histopathological changes in the lung. The efficacy of PM014 was compared with that of the recently developed anti-COPD drug, roflumilast. PM014 substantially inhibited immune cell infiltration (neutrophils, macrophages, and lymphocytes) into the airway. In addition, IL-6, TNF-α and MCP-1 were decreased in the BAL fluid of PM014-treated mice compared to cigarette smoke stimulated mice. These changes were more prominent than roflumilast treated mice. The
The smoking of tobacco continues to be the leading cause of premature death worldwide and is linked to the development of a number of serious illnesses including heart disease, respiratory diseases, stroke and cancer. Currently, cell line based toxicity assays are typically used to gain information on the general toxicity of cigarettes and other tobacco products. However, they provide little information regarding the complex disease-related changes that have been linked to smoking. The ethical concerns and high cost associated with mammalian studies have limited their widespread use for in vivo toxicological studies of tobacco. The zebrafish has emerged as a low-cost, high-throughput, in vivo model in the study of toxicology. In this study, smoke condensates from 2 reference cigarettes and 6 Canadian brands of cigarettes with different design features were assessed for acute, developmental, cardiac, and behavioural toxicity (neurotoxicity) in zebrafish larvae. By making use of this multifaceted ...
RATIONALE: Pathogenic T cells drive, or sustain, a number of inflammatory diseases. Chronic obstructive pulmonary disease (COPD) is an inflammatory lung disease associated with the accumulation of activated T cells. We previously demonstrated that chronic cigarette smoke (CS) exposure causes oligoclonal expansion of lung CD4(+) T cells and CD8(+) T cells in a mouse model of COPD, thus implicating these cells in disease pathogenesis.. OBJECTIVES: To determine whether T cells are pathogenic in a CS-induced mouse model of COPD.. METHODS: We transferred lung CD3(+) T cells from filtered air (FA)- and CS-exposed mice into Rag2(-/-) recipients. Endpoints associated with the COPD phenotype were then measured.. MEASUREMENTS AND MAIN RESULTS: Here, we demonstrate that chronic CS exposure generates pathogenic T cells. Transfer of CD3(+) T cells from the lungs of CS-exposed mice into Rag2(-/-) recipients led to substantial pulmonary changes pathognomonic of COPD. These changes included monocyte/macrophage ...
Learning, knowledge, research, insight: welcome to the world of UBC Library, the second-largest academic research library in Canada.
Cigarette smoking is a major cause of lung cancer; however, it has been difficult to reproduce the tumorigenicity of cigarette smoke in preclinical animal models. Increased lung tumorigenicity has been reported in A/J mice exposed for 5 months to an environmental tobacco smoke surrogate or to cigarette mainstream smoke (MS) followed by 4 months without further exposure. Here, we report on MS-induced lung tumor formation in male a/j mice after 18 months of exposure to a continuous flow of MS (6 H/day, 5 D/wk) at total particulate matter concentrations of 150 and 300 mg/m(3). Animal health, housing conditions, test atmosphere characterization, and markers for MS exposure (e.g., carboxyhemoglobin) were carefully monitored over the 18-month period to ensure the stability of the experimental conditions. Body weight gain was reduced dose-dependently in MS-exposed groups. An influx of neutrophils (up to 33% of leukocytes) and lymphocytes (up to 21%) into the bronchoalveolar space, indicating severe ...
Maternal smoking has been recognized as a common cause of low birth weight, preterm birth and the decrease of gestational age period. Unfortunately, there is an increasing interest within public especially woman in Iran in the tobacco products consumption. On the other hand, the deleterious effect of maternal smoking on human fetus in pregnancy period especially in the first trimester encouraged us to investigate toxicity mechanisms of cigarette smoke on mouse fetus mitochondria. For this purpose different concentrations of standardized cigarette smoke extract (1, 10 and 100%) were administrated on mitochondria isolated from fetus of NMRI mice on the 15 day of gestation. Our results showed a significant increase in ROS formation, lipid peroxidation, mitochondrial membrane potential collapse, mitochondrial swelling and finally a decrease in ATP concentration in the CSE-treated isolated fetus mitochondria. Our results suggest that CSE-induced embryo toxicity is the result of disruptive effect on
In May 2016, the U.S. Food and Drug Administration (FDA) issued a final rule deeming cigar products within scope of their regulatory authority. Under this regulation the FDA will require manufacturers to report the quantities of Harmful and Potentially Harmful Constituents (HPHCs) in cigar filler and smoke. Currently, FDA has not indicated that the list of constituents for cigars would differ from that of the list of constituents provided for tobacco smoke, and thus would require the analysis of ammonia in cigar smoke. We previously showed that the CORESTA Recommended Method No.
Many ventilating systems do not function properly due to the fouling of ducts and components. There is a need to study a wide range of different duct systems, in order to reduce the deposition rate in absolute terms, thus arriving at a more efficient system. A preliminary study is conducted in the laboratory to determine the flow behaviour of aerosol particles in relation to the airflow for ducts of various aspect ratios. A constant-injection tracergas technique is used to determine the airflow rate in the ductwork. SF6 tracer gas and smoke particles were injected at a constant rate into the inlet of each duct and their tracer-gas concentrations in ppm and smoke-particle concentration in mg m-3 were monitored at various points downstream. Algorithms were established for the deposition rate of smoke particles in various ducts. The results showed that the deposition rate of smoke particles was strongly influenced by the airflow rate and size of the duct. © 1997 Published by Elsevier Science Ltd ...
Every year there are thousands of house fires in the United Kingdom. The emergency services are actually called out to around 140 house fires every single day. It is almost impossible to completely fireproof a house, so it is highly important that homeowners do everything in their power to minimise the damage if there is an incident. The small price that you pay for your smoke alarm will be well-worth it. Installing a smoke alarm in your house may be one of the most important things that you ever do.. About 500 people per year die in house fires in the United Kingdom and over 10,000 people are injured. Some of these injuries are life-changing. Many of these deaths and injuries could have been avoided if these homes had had working smoke detectors.. A smoke alarm is set up to detect relatively small amounts of smoke in the air. Ionisation alarms are better at detecting the smoke that is produced by fast-spreading fires, whereas optical alarms are better at detecting larger smoke particles such as ...
In vitro biological studies on cigarette smoke have usually been made using either cigarette smoke condensate--obtained by trapping the particulate phase of smoke on a filter, or soluble smoke components--obtained by trapping cigarette smoke in buffer solution. However, these approaches may not trul …
4275 Alterations in signaling pathways associated with oxidative stress, inflammation and DNA damage are often observed in cells exposed to complex chemical mixtures including cigarette smoke. Our laboratory previously reported that smoke condensate from cigarettes that primarily heat tobacco produce less change in p21, GADD45, COX-2, IL-8, HO-1 and HSP70 mRNA levels in normal human bronchial epithelial (NHBE) cells than smoke condensate from tobacco-burning cigarettes. The NFκB signal transduction pathway is reported to mediate in part the response of bronchial epithelial cells to cigarette smoke through the activation of several genes; including genes coding for COX-2, HO-1, and HSP-70. The objective of this study was to characterize and compare the effect of smoke condensates from tobacco-heating and tobacco-burning cigarettes on NF-κB promoter activation. Cigarette smoke condensate (CSC) was prepared from Kentucky reference 2R4F cigarettes, a tobacco-burning product designed to represent ...
Smoking also tends to leave an oily residue on other surfaces, which can contribute to a lingering smoke smell even if you vacuum and use absorbent materials like baking soda and activated charcoal. HEPA: This type of air filter is rated to use mechanical filtration to capture 99.97% of particles 0.3 microns in size, which includes some smoke particles. Leave them for a day and replace them if the smell lingers. Carpet is a sponge for odors and should be replaced, along with any furniture that is still in the house. Luckily, there are ways to fix this. Smelling Cigarette Smoke (Phantosmia): What could it mean? Find a smoke remediation specialist through websites such as Yelp, or ask for referrals from your local home improvement center. The smells vary from person to person but are usually unpleasant, such as burnt toast, metallic, or chemical smells. The smell of cigarette smoke, when there is no odor present, can be an indication that a persons olfactory nerve has been damaged in some way. If ...
The invention relates to a mixture of two particulate phases which is used in the production of a green compact that can be sintered at higher temperatures. According to the invention, A) the first phase contains particles that consist of a metal and/or a metal alloy and/or a metal compound, and B) the second phase contains particles from the group of the inorganic compounds which do not release any decomposition products at temperatures of more than 400 °C that are interstitially soluble in the sintering metal phase and/or that react with said phase to stable compounds. The inventive mixture, by providing the second phase, is effective in supporting the fine structure of the first phase against the forces of surface tension during the sintering process. During sintering, the second phase remains thermally stable and substantially chemically inert with respect to the first phase.
Cigarette smoke is a strong risk factor for cardiovascular disease. However, the underlying molecular mechanisms that lead to cigarette smoke-associated cardiovascular disease remain elusive. With functional and molecular methods, we demonstrate for the first time that lipid-soluble cigarette smoke
There is a lot of interest in the health benefits of dietary carotenoids and on the relationship of these compounds with smoke. In particular, it is unknown if the enhanced cancer risk observed in smokers following beta-carotene supplementation can be also found using other carotenoids. Here, we stu …
Semantic Scholar extracted view of Some effects of experimentally-produced cigarette smoke on the growth, vitamin C metabolism and organ weights of guinea-pigs. by Robert E. Hughes et al.
As early as the 15th century Leonardo da Vinci commented at length on the difficulty of assessing smoke, and distinguished between black smoke (carbonized particles) and white smoke which is not a smoke at all but merely a suspension of harmless water particulates.[26] Smoke from heating appliances is commonly measured in one of the following ways: In-line capture. A smoke sample is simply sucked through a filter which is weighed before and after the test and the mass of smoke found. This is the simplest and probably the most accurate method, but can only be used where the smoke concentration is slight, as the filter can quickly become blocked.[27] The ASTM smoke pump is a simple and widely used method of in-line capture where a measured volume of smoke is pulled through a filter paper and the dark spot so formed is compared with a standard. Filter/dilution tunnel. A smoke sample is drawn through a tube where it is diluted with air, the resulting smoke/air mixture is then pulled through a ...

The oviduct is an exquisitely designed organ that functions in picking-up ovulated oocytes, transporting gametes in opposite directions to the site of fertilization, providing a suitable environment for fertilization and early development, and transporting preimplantation embryos to the uterus. A variety of biological processes can be studied in oviducts making them an excellent model for toxicological studies. This review considers the role of the oviduct in oocyte pick-up and embryo transport and the evidence that chemicals in both mainstream and sidestream cigarette smoke impair these oviductal functions. Epidemiological data have repeatedly shown that women who smoke are at increased risk for a variety of reproductive problems, including ectopic pregnancy, delay to conception, and infertility. In vivo and in vitro studies indicate the oviduct is targeted by smoke components in a manner that could explain some of the epidemiological data. Comparisons between the toxicity of smoke from different types
The study recreated the effects of cigarette smoke on cancerous cells of the mouth. Half the cells were exposed to cigarette smoke only, while the other half were exposed to a saliva and cigarette smoke mixture. The researchers then studied the cells to assess whether the saliva and smoke mixture would speed up the cancers development.. The longer the mouth cells were exposed to the contaminated saliva, the more they were damaged. The researchers also found that the cigarette smoke destroyed various salivary components, including protective ones such as peroxidase, the most important antioxidant contained in saliva. Antioxidants are molecules that help protect the body against cancer.. Nagler said the reaction between certain components of saliva and the low reactive free radicals contained in cigarette smoke results in the production of highly active hydroxyl free radicals. Free radicals, oxygen by-products created by normal cell metabolism, possess unpaired electrons. In a process called ...
Although many studies have investigated the toxicity of PM2.5 on airway cells and other cell types [33-35], the biological mechanisms remain unclear. Therefore, we investigated the effects of PM2.5 on the NF-κB pathway in cell apoptosis to understand the implications of PM2.5 in Beijings air.. The cell viability rate was 72.28% at 200 μg/ml of PM2.5 in our study, and this concentration level was used as the main exposure concentration for testing other endpoints. This concentration was higher than previous studies that used total particulate matter (TPM) from mainstream cigarette smoke with CHO cell lines [36-38]. Cigarette smoke is a dynamic aerosol composed of more than 4000 chemical components. The main components include nicotine, alkaloids, tar, CO, polycyclic aromatic hydrocarbons, hydroxyl compounds, and heavy metals [39, 40]. Particle matter is a complex mixture with a physical nucleus that is composed of elemental carbon, nitrates, sulfates, various metals and organic compounds [41]. ...
Let us assume a situation similar to the figure above. The smoker produces a cloud of positive charged particles and, because previous clouds have also charged the smokers clothes positively, the particle cloud is repelled. Because the TV screen is also charged positively, it also repels the cloud. On the other hand, the non-smoker is not charged, being more or less neutral. The repelled smoke particles will thus indeed flow in the direction of the non-smoker. When the non-smoker wears clothing containing polyethylene or rayon fibers, then it is likely that he/she is charged negatively according to the triboelectric series. He/she will then attract the smoke particles ...

Natural News) People may be unaware of being exposed to smoke, and children whose parents do are at risk. A study from Tel Aviv University shows that many smoking parents make false assumptions and have a lack of awareness when it comes to where and when children are exposed to second-hand smoke.. According to lead researcher Dr. Lauren Rosen of TAUs School of Public Health and Sackler Faculty of Medicine, many parents who smoke believe that they take adequate measures to protect their children from the damages that cigarette smoke can cause. However, the study found that most of these parents are not aware of some of the exposure. The study, published in Nicotine and Tobacco Research, reports that parents believe that if they did not see or smell the smoke, their children were not exposed.. Previous studies show that 85 percent of smoke is invisible, and many components of smoke are odorless. Furthermore, a smokers sense of smell is unreliable, since the effects of tobacco and nicotine damage ...
We already know that smoking cigarettes harms human respiratory and immune cells, and now weve shown that, on the flipside, smoke can also stress out invasive bacteria and make them more aggressive, said senior author Laura E. Crotty Alexander, MD, assistant clinical professor of medicine at UC San Diego and staff physician at the Veterans Affairs San Diego Healthcare System.. Crotty Alexander is a pulmonologist who sees many patients who smoke cigarettes. She also sees many MRSA infections, and that got her wondering if one might influence the other. To test the hypothesis, Crotty Alexander and her team infected macrophages, immune cells that engulf pathogens, with MRSA.. Some of the bacteria were grown normally and some were grown with cigarette smoke extract. They found that while the macrophages were equally able to take up the two bacterial populations, they had a harder time killing the MRSA that had been exposed to cigarette smoke extract..

For me personally, it was useless, said Georges Touaichi, a 22-year-old San Diego hotel worker who tried e-cigarettes but went back to smoking after a day or two.. But when the cessation aids were coupled with cash, the success rates tripled.. Among 6,006 employees at 54 USA -based companies, the six-month smoking abstinence rates for all the strategies were less than 3 percent. Over time, we have come to know the real dangers of smoking, and I think raising the age to purchase cigarettes from 18 to 21 will help to get cigarettes away from high-school aged children. In other words, none of these strategies were much more effective than the others.. These data suggest that cigarette smoke components may impair hind limb muscle vascular structure, fatigue resistance and myofiber calcium handling, and these changes ultimately affect contractile efficiency of locomotor muscles independent of a change in lung function, researchers said.. One theory is that certain types of lung cancer are more ...
To our knowledge, this is the first study compares frequency of PH in the subjects exposed to biomass and tobacco smoke, and describes the possible causes of PH in these patients groups. In the present study, the most relevant findings were that patients exposed to BS had more frequent PH presence and less FVC %, whereas TS group had less frequent PH presence and FEV1 %. Finally, biomass smoke exposed group had more frequent PH especially in the moderate level COPD cases.. BS is composed of a relatively equal mixture of gases and particles and can penetrate deeply into the lung, producing a variety of morphologic and biochemical changes (10, 11). A recent meta-analysis, which reviewed risk of COPD from exposure to BS, concluded that BS exposure is a clear risk factor for COPD (12). It has reported that BS related COPD cases clinical characteristics, quality of life, and mortality rate were similar in degree to that of tobacco smokers (13). To date, the frequency of PH was not compared in these ...

See tips for reducing indoor air pollution.. Cigarette smoke. One of the most common and toxic indoor air pollutants is cigarette smoke. Experts believe about 85% of lung cancers are caused by cigarette smoke.footnote 2 Smoking, or even inhaling second-hand smoke, increases your risk of heart attack and stroke.. Tobacco smoke contains many chemicals, some of which can cause cancer. If you are a non-smoker and household members or co-workers will not stop smoking around you, ask that they smoke only in well-ventilated or isolated areas. Never smoke around children or allow them to be exposed to cigarette smoke, especially if they have asthma or allergies.. Exposure to cigarette smoke causes wheezing, coughing, and extra mucus (phlegm) in many children. Second-hand smoke also can cause fluid to build up in the inner ear, which can cause ear infections. Lower respiratory infections, such as pneumonia and bronchitis, are also risks. Sometimes these types of infections become serious enough to ...

Inhalation exposure to indoor surroundings pollutants and tobacco smoke increases the threat of developing tuberculosis (TB). Polluting of the environment and tuberculosis (TB) embody two from the preeminent complications connected with global general public health. While contact with air pollution is in charge of 1 in 8 fatalities internationally (1), 1.5 million deaths from TB and around 9 million new TB cases were reported in 2014 (2). Aerogenic contact with polluting of the environment particulate matter 1469925-36-7 IC50 (PM) represents a significant risk to general public health, in quickly developing towns of countries where TB can be endemic especially, influencing socioeconomically and environmentally disadvantaged communities primarily. PM can be a complex combination of solid and water contaminants thats released in to the atmosphere during combustion of coal, real wood, gasoline, diesel, or fossil fuels, as well as from natural sources (road dust, fires, volcanic emissions, etc.) ...
Canada has already had its share of wildfires this season, and the smoke from these wildfires is slowly drifting south over the United States Midwest. The drifting smoke can be seen in this Terra satellite image over Lake Michigan, as well as parts of Minnesota, Wisconsin, Indiana and Ohio. The smoke released by any type of fire (forest, brush, crop, structure, tires, waste or wood burning) is a mixture of particles and chemicals produced by incomplete burning of carbon-containing materials. All smoke contains carbon monoxide, carbon dioxide and particulate matter (PM or soot). Smoke can contain many different chemicals, including aldehydes, acid gases, sulfur dioxide, nitrogen oxides, polycyclic aromatic hydrocarbons (PAHs), benzene, toluene, styrene, metals and dioxins.
Leukocytosis is one of the well-recognized side effects of cigarette smoking. The dose of smoking plays a major role in causing smoke-induced leukocytosis. Immunopharmacology bases most of their test results based on cigarette drug test, though the exact mechanism of smoke-induced variations in the immune response is poorly understood, frequent cigarette smoke test positive in many cases has lead to change in the primary immune response of the smoker. It is also reported to cause tangible effects on the secondary antibody response of the smoker! It is due to this concept cotinine blood test is being an important part in determining the medical insurance limitations.. Cigarette smoking is a dangerous mix of complex substances and most of them can potentially influence the immune system. The B cell membrane signal transduction pathway is greatly affected by nicotine which is present in cigarette smoke. The levels of these harmful substances can be studied at random using the Cotinine saliva ...
Description. Build your own BBQ Smokehouse. The Bradley Smokers Smoke Generator allows you to make your own food smoking cabinet very easily. The Bradley Smoke Generator is a highly adaptable unit that allows you to retrofit almost any small structure into a smoke house. The unit consists of two parts. The Smoke Generator is fabricated from powder-coated steel, and fulfills the same purpose as the smoke generator which is fitted to the Original Bradley Smoker - advancing the bisquettes onto the heat element at a rate of one every twenty minutes. The Smoke Generator design is reminiscent of the older models of Bradley Smoker, now superceded. This is of no consequence as the controls are limited to a power on / off switch, and a bisquette advance button, used to position the first bisquette on the burner. Thereafter, bisquettes feed automatically. The second part of the apparatus consists of a stainless steel face-plate, with an adjustable collar onto which the smoke generator fits by means of two ...
OBJECTIVE To identify and characterize alterations seen on HRCT scans in nonsmoking females with COPD due to wood smoke exposure. METHODS We evaluated 42 nonsmoking females diagnosed with wood smoke-related COPD and 31 nonsmoking controls with no history of wood smoke exposure or pulmonary disease. The participants completed a questionnaire regarding demographic data, symptoms, and environmental exposure. All of the participants underwent spirometry and HRCT of the chest. The COPD and control groups were adjusted for age (23 patients each). RESULTS Most of the patients in the study group were diagnosed with mild to moderate COPD (83.3%). The most common findings on HRCT scans in the COPD group were bronchial wall thickening, bronchiectasis, mosaic perfusion pattern, parenchymal bands, tree-in-bud pattern, and laminar atelectasis (p | 0.001 vs. the control group for all). The alterations were generally mild and not extensive. There was a positive association between bronchial wall thickening and hour

Airway inflammation is likely to play a critical role in the genesis and progression of tobacco smoke-induced airway disease. Soluble epoxide hydrolase (sEH) is involved in the metabolism of endogenous chemical mediators that play an important role in inflammation. Epoxyeicosatrienoic acids (EETs) have demonstrated antiinflammatory properties, and hydrolysis of these epoxides by sEH is known to diminish this activity. To examine whether acute tobacco smoke-induced inflammation could be reduced by a sEH inhibitor, 12-(3-adamantane-1-yl-ureido)-dodecanoic acid n-butyl ester was given by daily ...
Although there are several choices to make in selecting the right smoke alarms to buy, the most important thing to remember is that smoke alarms save lives. For that reason, you should install a smoke alarm if your home does not have one.. Smoke alarms may contain different or multiple sensors. There are two main types of smoke alarms, which are categorized by the type of smoke detection sensor, ionization and photoelectric, used in the alarm. A smoke alarm uses one or both methods, sometimes with a heat detector, to warn of a fire.. Ionization detectors contain a chamber with two plates that generate a small, continuous electric current. When smoke enters the ionization chamber, the smoke particles disrupt the current flow, which triggers the alarm.. Photoelectric detectors use a light beam and light receptor (photocell). When smoke is present between the light and receptor, depending on the type of smoke chamber configuration, the reduction or increase of light on the photocell sensor triggers ...
Cigarette smoke exposure is the key initiator of chronic inflammation, alveolar destruction, and the loss of alveolar blood vessels that lead to the development of chronic obstructive pulmonary disease (COPD) which is comprised of emphysema and chronic bronchitis. Exposure to secondhand smoke (SHS) is the major risk factor for non-smokers to develop emphysema. While the first-hand smoke is directly inhaled by smokers, passive smoking occurs when non-smokers are involuntary exposed to environmental tobacco smoke also known as second hand smoke (SHS). SHS is a mixture of 2 forms of smoke that come from burning tobacco: side stream smoke (smoke that comes from the end of a lit cigarette, pipe, or cigar) and mainstream smoke (smoke that is exhaled by a smoker). These two types of smoke have basically the same composition, however in SHS many toxic components are more concentrated than in first-hand smoke, therefore more hazardous for peoples health. Several pathological events have been implicated in the
In spite of the major role played by cigarette smoking in the epidemiology of lung cancer, it is very difficult to reproduce the carcinogenicity of this complex mixture in animal models. We implemented a series of pilot experiments in three mouse strains, exposed either to environmental cigarette smoke (ECS) or mainstream cigarette smoke (MCS) or its condensate (MCSC). The whole-body exposure of Aroclor-treated A/J mice to ECS resulted in a rapid and potent induction of micronuclei in peripheral blood erythrocytes. After 6 months of exposure, 6 h a day, followed by 4 months of recovery in filtered air, both lung tumor incidence and multiplicity were significantly increased as compared to sham-exposed mice (77.8% vs. 22.2%, and 1.11±0.26 vs. 0.22±0.15, means ± SE). Multiple i.p. injections of butylated hydroxytoluene did not significantly enhance the tumor yield. Another experiment confirmed the responsiveness of A/J mice exposed to ECS for 5 months, followed by 4 months of recovery in air ...
This case-control analysis presents odds ratios for active and passive cigarette smoke exposure and cervical intraepithelial neoplasia of levels II and III (CIN II and CIN III) while controlling for confounders. From 1987 to 1988, 103 biopsy-conformed incident cases of CIN II or III and 268 controls with normal cervical cytology were enrolled. Seventy % of cases were cigarette smokers, while only 30% of controls had ever smoked. The adjusted odds ratio for current cigarette smoking was 3.4 (95% confidence interval, 1.7-7.0). The following confounders were included in logistic regression models: age, race, education, number of sex partners, contraceptive use, sexually transmitted disease history, and Pap smear history. The risk of CIN II/III increased with increasing years of cigarette smoking and with increasing pack-years of exposure. Smoking was associated more strongly with CIN III than CIN II. The effect of passive cigarette smoke exposure was explored separately for smokers and nonsmokers and was
Wood smoke is more damaging than tobacco smoke.. While wood smoke is similar to second hand tobacco smoke, research findings indicate that second hand wood smoke has potentially an even greater ability to damage your health and the health of your family and loved ones.. Comparing tobacco smoke (TS) and wood smoke (WS) using electron spin resonance (ESR) reveals something quite startling. TS does damage in the body for 30 seconds after it is inhaled. WS continues to be chemically active and can cause damage to the cells in the body for 20 minutes or 40 times longer (Pryor, 1992). What does that mean? Some of the components in WS are atoms or molecules in need of at least one unpaired electron to become stable compounds. They are called free radicals. Free radicals interact with your body. They borrow these electrons from the body, leaving body cells unstable - or injured if you will. Some of the cells then die. Other cells are altered and will function differently. The cells give off by products ...
Cigarette smoke exposure is associated with chronic and enhanced pulmonary inflammation characterized by increased cytokine production and leukocyte recruitment to the lung. Although the aryl hydrocarbon receptor (AhR) is well-known to mediate toxic effects of environmental contaminants, the AhR has emerged as a suppressor of acute cigarette smoke-induced neutrophilia. As there is currently no information on the AhR prevention of lung inflammation due to varied and prolonged exposure regimes, we exposed control and AhR-/- mice to cigarette smoke for 2 weeks (sub-chronic exposure) utilizing low and high exposure protocols and evaluated pulmonary inflammation. Sub-chronic cigarette smoke exposure increased pulmonary neutrophilia dose-dependently in AhR-/- mice. There was no difference between smoke-exposed AhR+/- and AhR-/- mice in the expression of cytokines associated with neutrophil recruitment. However, expression of pulmonary intercellular adhesion molecule-1 (ICAM-1), an adhesion molecule ...
Description: Fire smoke is a major contributor to both particulate matter (PM) and ozone exposure in urban centers. Epidemiological, clinical, and toxicological studies have demonstrated a casual relationship between these pollutants and cardiovascular and respiratory related deaths and illnesses. Given the expected increase in fire events due to climate and landscape changes, quantifying health effects of wildfire smoke and developing real-time tools to help air quality managers mitigate the effects of exposure are sorely needed. We comprehensively assessed the health risks posed by smoke exposure, and constructed new tools to estimate and forecast smoke concentration levels and associated health effects. We accomplished these goals with four specific aims. In Aim 1, we compared the chemical composition of fine PM emanating from fire smoke with typical urban PM in the US. This information fills an important gap in the literature, and enabled us to distinguish between smoke and non-smoke related ...
ing is the single most preventable cause of death in our society. Based on current patterns, smoking will kill about 650 million people alive in the world today. If these patterns continue, tobacco-caused deaths worldwide are expected to increase from about 5 million per year today to about 10 million per year by the 2030s. Most of these deaths will happen in developing countries. What are the dangers of environmental tobacco smoke? Environmental tobacco smoke (ETS), also known as passive smoking or secondhand smoke, occurs when non-smokers breathe in other peoples tobacco smoke. This includes mainstream smoke (smoke that is inhaled and then exhaled into the air by smokers) and sidestream smoke (smoke that comes directly from the burning tobacco in cigarettes). ETS contains the same harmful chemicals as the smoke that smokers inhale. In fact, because sidestream smoke is formed at lower temperatures, it has even larger amounts of some toxic and cancer-causing substances than mainstream smoke. ...
Smoking is the main risk factor for the development of the chronic obstructive pulmonary disease (COPD) in Western countries. Recent studies suggest that IL-17A and Th17 cells play a role in the pathogenesis of COPD. We used a murine model of chronic cigarette smoke (CS) exposure to explore the contribution of IL-17A to CS-induced lung damage and loss of pulmonary function. Histology and morphometry showed that IL-17A deficiency spontaneously resulted in a loss of lung structure under basal conditions. Even though inflammatory markers [IL-1β and granulocyte colony-stimulating factor (G-CSF)] were decreased in IL-17A-deficient mice (IL-17A(-/-)) exposed to CS compared with wild-type (WT) mice, IL-17A(-/-) mice were per se not protected from CS-induced emphysematous disease. Assessment of pulmonary function showed that IL-17A(-/-) mice were partially protected from CS-induced changes in total lung capacity. However, the respiratory elastance decreased and respiratory compliance increased in ...

Purpose: : Cigarette smoke is the single greatest environmental risk factor for age-related macular degeneration, and the effects of smoking are partially retained years after cessation. We have shown that cigarette smoke causes more severe CNV in mice. One proposed mechanism for the long lasting effect of smoke is toxic damage to vascular cells or extracellular matrix in blood vessels, which would persist long after smoke cessation. Another possibility is smoke-related alterations in myeloid or vascular progenitors in the marrow. In this case, the long term consequences of smoke would be retained in the bone marrow, but not in the peripheral tissue. We performed an experiment to test this distinction. Methods: : We performed bone marrow transplantation (BMT) by isolating bone marrow from mice exposed to full stream cigarette smoke two hrs daily for four weeks transferred into normal, non-exposed recipients; or vice versa, marrow from non-exposed mice into smoke-exposed recipients. Then, ...
For people with underlying heart and lung problems, effects from wildfire smoke can accumulate over shorter periods of time, Joseph said, but that can also depend on how much wildfire smoke people are exposed to and the chemical makeup of that smoke.. Its not a hard and fast rule as to how fast (health problems) come on, Joseph said.. Smoke also contains the same kind of particles as wood fired stoves, factories and restaurants, although they usually have smaller concentrations of dangerous particles. That means, once wildfire smoke goes away, people could still be exposed to the same irritants.. It could be a continuous, ongoing problem, he said.. Related: New Air Quality App Maps Oregon Wildfire Smoke Dangers. For people who dont have underlying health issues, long-term exposure to wildfire smoke can also damage airways, causing asthma-like issues, Joseph said.. Earlier studies have shown pollution from wildfire smoke is worse than scientists previously thought. In a 2017 report, ...

Methods We generated sidestream and mainstream cigarette smoke with a smoking machine, diluted it with conditioned filtered air, and passed it through a 6 m3 flow reactor with air exchange rates that matched normal residential air exchange rates. We tested the effects of 60 min aging on the concentration of 16 PAHs, nicotine, cotinine and tobacco-specific nitrosamines. We also measured sorption and deposition of nicotine, cotinine and tobacco-specific nitrosamines on materials placed within the flow reactor.. ...
The radium isotopes 226Ra and 228Ra were analyzed in surface water at six points in the neighborhood of a mine of phosphate, associated with uranium, in the region of Santa Quitéria, state of Ceará, Brazil. Water samples were collected during twenty months, filtered and the concentrations of activity determined in the soluble and particulate phases. The results were analyzed using the Principal Component Analysis (PCA) for ordination of environmental data, and also by ANOVA, Tukey and Z tests to compare sets of data considering the radionuclides, the two analyzed phases and the six collecting points. The PCA identified four groups that included all collecting points, using aggregation features such as radionuclide and analyzed phase. The first group is composed by the samples of 226Ra in the soluble phase; the second group by samples of 226Ra in the particulate phase; the third one by 228Ra in the soluble phase, and finally, the fourth group by 228Ra in the particulate phase.

Its the time of year when many of us warm to a crackling fire in the open hearth, or turn to wood burning stoves to manage heating bills. But November is also COPD Awareness month - and new research suggests that Chronic Obstructive Pulmonary Disease is significantly aggravated by exposure to wood smoke (including smoke from wildfires that also rage around this time of year).. Of the 1,861 mainly female (81%) former and current smokers (ages 40-75) enrolled in a University of Mexico study, 28% reported being exposed to wood smoke, be it from a fireplace, stove, or outdoor campfires. Those smokers and non-smokers around wood smoke were 9% more likely to have trouble breathing - and specifically 11% more likely to suffer bronchitis symptoms. The effect is all the more worrisome given that COPD is the fourth leading cause of death in the U.S. ...
Mathis C, Poussin C, Weisensee D, Gebel S, Hengstermann A, Sewer A, Belcastro V, Xiang Y, Ansari S, Wagner S, Hoeng J, Peitsch M.. Philip Morris International, Neuchatel, Switzerland. The exposition of cigarette smoke on Human AIR-100 tissues shows equivalent results in MMP-1 release, gene expression and microRNA profiles to in vivo smokers tissue.. Abstract. Organotypic culture of human primary bronchial epithelial cells is a useful in vitro system to study normal biological processes and lung disease mechanisms, to develop new therapies, and to assess the biological perturbations induced by environmental pollutants. Herein, we investigate whether the perturbations induced by cigarette smoke (CS) and observed in the epithelium of smokers airways are reproducible in this in vitro system (AIR-100 tissue), which has been shown to recapitulate most of the characteristics of the human bronchial epithelium. Human AIR-100 tissues were exposed to mainstream CS for 7, 14, 21, or 28 min at the ...
In this study we found important structural differences between women with COPD with either biomass or tobacco smoke exposure. We found that participants exposed to biomass smoke had less emphysema, based on both qualitative and quantitative CT measures, than those exposed to tobacco smoke. In addition, less emphysema in the presence of similar airflow obstruction supports the argument that biomass smoke may lead to an airways disease phenotype. Although the quantitative CT scans did not show differences in airways metrics after adjusting for covariates, the radiologists rating showed worse air trapping in women exposed to biomass smoke. These results are consistent with the conclusions from the autopsy study by Rivera et al. [6], and, to our knowledge, represent the first direct comparison of COPD phenotypes in comparably obstructed living individuals exposed to biomass versus tobacco smoke, using questionnaire, exercise tolerance, lung function and MDCT data.. The body of evidence linking ...
A fire can spark and spread quickly, and the resulting smoke can spread for thousands of miles beyond the blaze. Winds have lifted the West Coast smoke over 3,000 miles across the United States to New York and into the Atlantic Ocean. The smoke from the recent Canadian and California wildfires, which as of this week covered 600,000 acres of the state, are also creating dangerous conditions for the thousands of passengers who travel by train in the area.. Correctly observing and predicting changes in wildfire locations and intensity over a widespread area is important to understanding how much smoke is generated from a wildfire. NOAAs new experimental HRRR(High-Resolution Rapid Refresh)-Smoke model is a major advancement in predicting the direction and height of wildfire smoke plumes. During the July 2018 Carr fire, detailed forecasts about smoke movement allowed Amtrak to make informed decisions about suspending part of their Coast Starlight service, which runs between Sacramento, California ...
This study is unique, wrote Hecht, an internationally recognized expert on cancer-causing substances found in cigarette smoke and smokeless tobacco. It is the first to investigate human metabolism of a PAH specifically delivered by inhalation in cigarette smoke, without interference by other sources of exposure such as air pollution or the diet. The results reported here should serve as a stark warning to those who are considering starting to smoke cigarettes ...
When a Smoke Composition utilizes the heat of chemical reaction between oxidizer and fuel, to vaporize the volatile ingredients present in the composition, it is known as Pyrotechnic Smoke Composition. In a Colour Smoke Composition the colour dye ingredients vaporize and subsequently the dye vapour condenses in atmosphere, giving Coloured Smoke. Some of the Pyrotechnic Colour Smoke Composition known in the art are made with binder or without binder. When a binder is used as a constituent of smoke composition, it is known as a Castable Smoke Composition. Pyrotechnic Favoured Castable Colour Smoke Composition have been used for signaling, marking, tracking, spotting and distress signaling ...
How to Make MORE SMOKE! (or Zen and the Art of Smoke System Installation) by Robert Osorio - The Flying Penguin Okay, lets talk smoke systems. I know, most of you are thinking hey, I havent got a giant scale plane with a gas engine, so I cant make smoke. NOT! I dont fly anything bigger than a .90 four-stroke, all my engines run on glow, and many of my planes have smoke systems onboard. I just love to burn up a clear blue sky with some smoke, and were not talking about a piss-ant dribble that can be mistaken for a rich engine run. No sir! Im talking nice, thick, white smoke thick enough to lay a haze across the runway on a low pass. Ive rigged many of my planes with smoke and Ive learned a lot from it. Ill be happy to share some of my hard earned insights with you (feel free to ignore them if youre feeling smug and superior, wont bother me). The most important thing is this: be prepared to experiment! If you dont like to experiment youre in the wrong hobby anyway - take up stamp ...

Four authoritative reviews of active smoking and breast cancer have been published since 2000, but only one considered data after 2002 and conclusions varied. Three reviews of secondhand smoke (SHS) and breast cancer (2004-2006) each came to different conclusions. With 30 new studies since 2002, further review was deemed desirable. An Expert Panel was convened by four Canadian agencies, the Ontario Tobacco Research Unit, the Public Health Agency of Canada, Physicians for a Smoke-Free Canada and the Canadian Partnership Against Cancer to comprehensively examine the weight of evidence from epidemiological and toxicological studies and understanding of biological mechanisms regarding the relationship between tobacco smoke and breast cancer. This article summarises the panels full report (http://www.otru.org/pdf/special/expert_panel_tobacco_breast_cancer.pdf). There are 20 known or suspected mammary carcinogens in tobacco smoke, and recognised biological mechanisms that explain how exposure to ...

Antenatal smoke exposure is an important risk factor for increased respiratory symptoms and lung function abnormalities in infants and children. In children less than 2 years of age, the risk for lower respiratory illness has been found to be increased by 72% if the mother smoked. Although the observed increase in risk is lower in older children, parental smoking may nevertheless account for approximately 20% of all asthma in childhood. Maternal environmental tobacco smoke (ETS) exposure during the third trimester of pregnancy is associated with asthma and allergy-related symptoms in pre-school children. Certain infants may have a genetic susceptibility to the adverse effects of environmental smoke exposure, both maternal during pregnancy and in infancy. Antenatal smoking exposure has been demonstrated in some, but not all, studies to have an adverse effect on lung function in infancy. In older children, antenatal smoke exposure has been associated with a reduction in airway function. The ...

Why Secondhand Smoke Could Be Harming Your Work Environment It is a well-known fact that smoking is extremely harmful towards your health. It is one of the leading causes of preventable death in America. However, did you know that over time secondhand smoke could also lead to cancer and other health issues in non-smokers? What is secondhand smoke? Secondhand smoke is when a non-smoker breaths in the smoke from a cigarette, as well as the smoke breathed out by the smoker. Why is secondhand smoke... Read More ...
The innate immune system is the first line of host defense and against viral pathogens via effector molecules, such as type-I interferon (IFN-α/β). Plasmacytoid dendritic cells (pDC) and monocyte-derived DC (moDC) are potent producers of IFN in response to viruses through the respective activation of recognition toll-like receptors (TLRs) and cytosolic RNA helicases MDA5 and RIG-I. Exposure to environmental tobacco smoke (ETS) is a risk factor associated with an increase in the frequency and severity of respiratory infections. However, the mechanisms by which ETS alters innate immune responses have not been fully elucidated. Therefore, we investigated the ability of pDC and moDC to respond to respiratory syncytial virus (RSV) and human metapneumovirus (hMPV) in the presence of cigarette smoke extract (CSE). In viral infected pDC and moDC, CSE led to a significant dose-dependent decrease in IFN-α production and in pDC alone cytokines IL-10 and IP-10. CSE treatment attenuated IFN induction by ...
ELDERS SPEAK. I know Grandpa told me that to smoke is wakan (holy). The smoke you inhale represents the spirits of everything you put into the pipe. When you breathe in the smoke, you are asking to become one with everything or to become whole. -- Dr. A.C. Ross (Enhanamani), Lakota The smoke allows us to go from the Seen World to the Spirit World. It is in the Spirit World where we are all connected. In this way, we can become one with all things. Our pipe is sacred. We need to be respectful of our medicine. When we smoke the pipe, we need to have good thoughts because these thoughts are shared with the Spirit World. The pipe, the smoke, the spirits, our thoughts - these things are Wakan.. Great Spirit, today, let my thoughts be Wakan..

This study will investigate the acute vascular effects and dose-dependent biological mechanisms of secondhand smoke on endothelial function and oxidative stress ...
This is very misleading, because it suggests that there is no way to avoid exposure to secondhand smoke. It seems to me that this is a dangerous message, because it tells the public that it is futile to even try to avoid exposure to secondhand smoke. The truth is that the public should be warned to try to avoid secondhand smoke exposure. And it is largely possible to avoid such exposure, especially when workplaces are smoke-free. While it is true that the vapor phase of secondhand smoke is not visible, I find that it is usually quite easy to smell secondhand smoke and know that it is there. In fact, I can usually detect the instant a smoker lights up in an environment, even if that person is located in a remote area of a room, far away from me. I dont see the point in trying to make people believe that it is pointless to even try to avoid secondhand smoke exposure ...
Many fire related deaths are caused by smoke inhalation. Smoke has many catastrophic effects on the body and can affect it in a number of ways such as pulmonary irritation, thermal damage and toxic poisoning.. Smoke inhalation takes place as a result of fires releasing harmful vapours and gases; victims are limited to clean air during the outbreak of fire, so the likeliness of breathing in toxic fumes rises, and they become at risk of smoke inhalation. House fires produce hundreds of these toxic fumes and harmful airborne chemicals due to the burning materials and restriction of oxygen.. ...
TY - JOUR. T1 - Environmental tobacco smoke. T2 - Experimental facts and societal issues. AU - Witschi, H.. AU - Pinkerton, Kent E. AU - Coggins, R. E.. AU - Penn, A.. AU - Gori, G. B.. PY - 1995. Y1 - 1995. N2 - Involuntary exposure to environmental tobacco smoke (ETS) in public or in working places is considered to be a serious risk to human health. This symposium addressed several issues of toxicological interest that are associated with exposure to ETS. Epidemiologic evidence obtained in human studies suggests that passive smoking increases the risk of developing lung cancer in nonsmokers and favors the development of respiratory tract infections in children. Comparatively few data are available from animal studies that provide experimental support of the observations. Exposure of pregnant or neonate rats to cigarette sidestream smoke (SS) affects developmental patterns of drug metabolizing enzymes that may persist up to 90 days. In young roosters, SS accelerates the development of ...
Anthracosis is a form of pneumoconiosis seen in coal workers, although other environmental factors such as cigarette smoke, air pollution and biomass fuels used extensively for cooking and home heating are also known to cause anthracosis.1-6 The terms hut lung or domestically acquired particulate lung disease have been used to describe the condition.7 A diagnostic feature in anthracosis is the black-colored deposits along the airway or lymph nodes. Problems caused by chronic exposure to biomass smoke and other particulates, such as dust or silicates from food grinding, are becoming more relevant in the western world due to immigration.7,8 Individuals may develop both physical and radiologic abnormalities of the lung presenting as chronic obstructive or fibrotic lung disease due to chronic exposure to smoke and particulates. Recent estimates attribute 1.5 to 2 million deaths per year worldwide to indoor air pollution, most of them (1 million) occurring in children younger than 5 years due to ...

The photoacoustic technique has been used in conjunction with an optical transmission measurement to determine the fraction of light absorbed in cigarette and acetylene smoke aerosols. At 0.5145-μm wavelength, the absorption-to-extinction fraction is 0.01 ± 0.003 for cigarette smoke and is in excellent agreement with predictions from Mie theory for smoke particles having a refractive index of 1.45-0.00133i and a median diameter in the 0.15-0.65-μm range. For acetylene smoke the absorbed fraction was 0.85 ± 0.05.. © 1980 Optical Society of America. Full Article , PDF Article ...
CS is a complex chemical mixture of gases and suspended particulate matter that contains a wide range of carcinogens, mutagens, and free radicals that can induce an array of DNA lesions (e.g., adducts, deletions, insertions, point mutations, structural chromosomal aberrations, aberrant sister chromatid exchanges, micronuclei, and single strand DNA breaks) that have been strongly implicated in the development and progression of human cancers by epidemiological studies [39-48]. Our previous studies showed that CS and cigarette smoke condensate (i.e., tar) can also directly induce DSBs in both normal and malignant lung cells [24, 35]. DSBs are a major type of DNA damage that can lead to translocations and chromosomal instability, two important mechanisms in the generation of malignant tumors [49]. Consequently, detection of DSBs and the various proteins that sense and orchestrate repair of these lesions may ultimately provide a more precise measurement of the potential cancer risk in individuals ...
