Cough frequency and cough receptor sensitivity to citric acid challenge during a simulated ascent to extreme altitude. (1/168)

The aim of this study was to determine the frequency of cough and the citric acid cough threshold during hypobaric hypoxia under controlled environmental conditions. Subjects were studied during Operation Everest 3. Eight subjects ascended to a simulated altitude of 8,848 m over 31 days in a hypobaric chamber. Frequency of nocturnal cough was measured using voice-activated tape recorders, and cough threshold by inhalation of increasing concentrations of citric acid aerosol. Spirometry was performed before and after each test. Subjects recorded symptoms of acute mountain sickness and arterial oxygen saturation daily. Air temperature and humidity were controlled during the operation. Cough frequency increased with increasing altitude, from a median of 0 coughs (range 0-4) at sea level to 15 coughs (range 3-32) at a simulated altitude of 8,000 m. Cough threshold was unchanged on arrival at 5,000 m compared to sea level (geometric mean difference (GMD) 1.0, 95% confidence intervals (CI) 0.5-2.1, p=0.5), but fell on arrival at 8,000 m compared to sea level (GMD 3.3, 95% CI 1.1-10.3, p=0.043). There was no relationship between cough threshold and symptoms of acute mountain sickness, oxygen saturation or forced expiratory volume in one second. Temperature and humidity in the chamber were controlled between 18-24 degrees C and 30-60%, respectively. These results confirm an increase in cough frequency and cough receptor sensitivity associated with hypobaric hypoxia, and refute the hypothesis that high altitude cough is due to the inhalation of cold, dry air. The small sample size makes further conclusions difficult, and the cause of altitude-related cough remains unclear.  (+info)

Acute mountain sickness is not related to cerebral blood flow: a decompression chamber study. (2/168)

To evaluate the pathogenetic role of cerebral blood flow (CBF) changes occurring before and during the development of acute mountain sickness (AMS), peak mean middle cerebral artery flow velocities () were assessed by transcranial Doppler sonography in 10 subjects at 490-m altitude, and during three 12-min periods immediately (SA1), 3 (SA2), and 6 (SA3) h after decompression to a simulated altitude of 4,559 m. AMS cerebral scores increased from 0. 16 +/- 0.14 at baseline to 0.44 +/- 0.31 at SA1, 1.11 +/- 0.88 at SA2 (P < 0.05), and 1.43 +/- 1.03 at SA3 (P < 0.01); correspondingly, three, seven, and eight subjects had AMS. Absolute and relative at simulated altitude, expressed as percentages of low-altitude values (%), did not correlate with AMS cerebral scores. Average % remained unchanged, because % increased in three and remained unchanged or decreased in seven subjects at SA2 and SA3. These results suggest that CBF is not important in the pathogenesis of AMS and shows substantial interindividual differences during the first hours at simulated altitude.  (+info)

Chemoprevention of tobacco smoke-induced lung tumors in A/J strain mice with dietary myo-inositol and dexamethasone. (3/168)

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)

Biotransformation and kinetics of excretion of methyl-tert-butyl ether in rats and humans. (4/168)

Methyl-tert-butyl ether (MTBE) is widely used as an additive to gasoline to increase oxygen content and reduce tail pipe emission of pollutants. Therefore, widespread human exposure may occur. To contribute to the characterization of potential adverse effects of MTBE, its biotransformation was compared in humans and rats after inhalation exposure. Human volunteers (3 males and 3 females) and rats (5 each, males and females) were exposed to 4 (4.5 +/- 0.4) and 40 (38.7 +/- 3.2) ppm MTBE for 4 h in a dynamic exposure system. Urine samples from rats and humans were collected for 72 h in 6-h intervals, and blood samples were taken in regular intervals for 48 h. In urine, MTBE and the MTBE metabolites tertiary-butanol (t-butanol), 2-methyl-1,2-propane diol, and 2-hydroxyisobutyrate were quantified; MTBE and t-butanol were determined in blood samples. After the end of the exposure period, inhalation of 40 ppm MTBE resulted in blood concentrations of MTBE 5.9 +/- 1.8 microM in rats and 6.7 +/- 1.6 microM in humans. The MTBE blood concentrations after inhalation of 4 ppm MTBE were 2.3 +/- 1.0 in rats and 1.9 +/- 0.4 microM in humans. MTBE was rapidly cleared from blood with a half-life of 2.6 +/- 0.9 h in humans and 0.5 +/- 0.2 h in rats. The blood concentrations of t-butanol were 21.8 +/- 3.7 microM in humans and 36.7 +/- 10.8 microM in rats after 40 ppm MTBE, and 2.6 +/- 0.3 in humans and 2.9 +/- 0.5 in rats after 4 ppm MTBE. In humans, t-butanol was cleared from blood with a half-life of 5.3 +/- 2.1 h. In urine samples from controls and in samples collected from the volunteers and rats before the exposure, low concentrations of t-butanol, 2-methyl-1,2-propane diol and 2-hydroxyisobutyrate were present. In urine of both humans and rats exposed to MTBE, the concentrations of these compounds were significantly increased. 2-Hydroxyisobutyrate was recovered as a major excretory product in urine; t-butanol and 2-methyl-1,2-propane diol were minor metabolites. All metabolites of MTBE excreted with urine were rapidly eliminated in both species after the end of the MTBE exposure. Elimination half-lives for the different urinary metabolites of MTBE were between 7.8 and 17.0 h in humans and 2.9 to 5.0 h in rats. The obtained data indicate that MTBE biotransformation and excretion are similar in rats and humans, and MTBE and its metabolites are rapidly excreted in both species. Between 35 and 69% of the MTBE retained after the end of the exposure was recovered as metabolites in urine of both humans and rats.  (+info)

Absence of prenatal developmental toxicity from inhaled arsenic trioxide in rats. (5/168)

A review of the literature revealed no published inhalational developmental toxicity studies of arsenic performed according to modern regulatory guidelines and with exposure throughout gestation. In the present study, inorganic arsenic, as arsenic trioxide (As(+3), As2O3), was administered via whole-body inhalational exposure to groups of twenty-five Crl:CD(SD)BR female rats for six h per day every day, beginning fourteen days prior to mating and continuing throughout mating and gestation. Exposures were begun prior to mating in order to achieve a biological steady state of As(+3) in the dams prior to embryonal-fetal development. In a preliminary exposure range-finding study, half of the females that had been exposed to arsenic trioxide at 25 mg/m3 died or were euthanized in extremis. In the definitive study, target exposure levels were 0.3, 3.0, and 10.0 mg/m3. Maternal toxicity, which was determined by the occurrence of rales, a decrease in net body weight gain, and a decrease in food intake during pre-mating and gestational exposure, was observed only at the 10 mg/m3 exposure level. Intrauterine parameters (mean numbers of corpora lutea, implantation sites, resorptions and viable fetuses, and mean fetal weights) were unaffected by treatment. No treatment-related malformations or developmental variations were noted at any exposure level. The no-observed-adverse-effect level (NOAEL) for maternal toxicity was 3.0 mg/m3; the NOAEL for developmental toxicity was greater than or equal to 10 mg/m3, 760 times both the time-weighted average threshold limit value (TLV) and the permissible exposure limit (PEL) for humans. Based on the results of this study, we conclude that arsenic trioxide, when administered via whole-body inhalation to pregnant rats, is not a developmental toxicant.  (+info)

Effects of a thirteen-week inhalation exposure to ethyl tertiary butyl ether on fischer-344 rats and CD-1 mice. (6/168)

The 1990 Clean Air Act Amendments require that oxygenates be added to automotive fuels to reduce emissions of carbon monoxide and hydrocarbons. One potential oxygenate is the aliphatic ether ethyl tertiary butyl ether (ETBE). Our objective was to provide data on the potential toxic effects of ETBE. Male and female Fisher 344 rats and CD-1 mice were exposed to 0 (control), 500, 1750, or 5000 ppm of ETBE for 6 h/day and 5 days/wk over a 13-week period. ETBE exposure had no effect on mortality and body weight with the exception of an increase in body weights of the female rats in the 5000-ppm group. No major changes in clinical pathology parameters were noted for either rats or mice exposed to ETBE for 6 (rats only) or 13 weeks. Liver weights increased with increasing ETBE-exposure concentration for both sexes of rats and mice. Increases in kidney, adrenal, and heart (females only) weights were noted in rats. Degenerative changes in testicular seminiferous tubules were observed in male rats exposed to 1750 and 5000 ppm but were not seen in mice. This testicular lesion has not been reported previously for aliphatic ethers. Increases in the incidence of regenerative foci, rates of renal cell proliferation, and alpha2u-globulin containing protein droplets were noted in the kidneys of all treated male rats. These lesions are associated with the male rat-specific syndrome of alpha2u-globulin nephropathy. Increases in the incidence of centrilobular hepatocyte hypertrophy and rates of hepatocyte cell proliferation were seen in the livers of male and female mice in the 5000-ppm group, consistent with a mitogenic response to ETBE. These two target organs for ETBE toxicity, mouse liver and male rat kidney, have also been reported for methyl tertiary butyl ether and unleaded gasoline.  (+info)

Developmental toxicity evaluation of inhaled toluene diisocyanate vapor in CD rats. (7/168)

Mated female CD (Sprague-Dawley) rats, 25/group, were exposed to toluene diisocyanate (TDI) vapor, for six h/day on gestational days (gd) 6 through 15, at 0.00, 0.02, 0.10, or 0.50 p.p.m.. Maternal clinical signs, body weights, and feed and water consumption were recorded throughout gestation. At termination (gd 21), maternal body, gravid uterine, and liver weights were recorded. Corpora lutea were counted, and implantation sites were identified: resorptions and dead and live fetuses. All live fetuses were examined for external alterations. One-half of the live fetuses/litter were examined for visceral (including craniofacial) alterations. The remaining intact fetuses/litter were stained with alizarin red S and examined for ossified skeletal alterations. Maternal toxicity at 0.50 ppm consisted of reduced body weights, body weight gains, feed consumption, and clinical signs of toxicity. Water consumption was unaffected. Gestational parameters exhibited no significant treatment-related changes, including pre- and postimplantation loss, sex ratio/litter, or fetal body weights/litter. Incidences of individual malformations, malformations by category (external, visceral, and skeletal), total malformations, individual external and visceral variations, variations by category, and total variations were unaffected. Of 111 skeletal variants observed, only 1, incidence of poorly ossified cervical centrum 5, was increased at 0.50 ppm, indicating possible minimal fetotoxicity, although it occurred in the absence of any other indications of developmental toxicity. Therefore, exposure to TDI vapor by inhalation, during major organogenesis in CD rats, resulted in maternal toxicity and minimal fetotoxicity at 0.50 ppm no observed adverse effect level (NOAEL) for maternal and developmental toxicity was 0.10 ppm. No treatment-related embryotoxicity or teratogenicity was observed.  (+info)

Two-generation reproductive toxicity study of inhaled toluene diisocyanate vapor in CD rats. (8/168)

Twenty-eight 42-day-old pups/sex/group (F0) were exposed to toluene diisocyanate vapor (TDI; 80% 2,4-TDI, 20% 2,6-TDI) by inhalation at 0.0, 0.02, 0.08, or 0.3 ppm, 6 h/day, 5 days/week, for 10 weeks, then mated within groups for 3 weeks, with exposure 7 days/week during mating, gestation, and lactation. F0 maternal animals were not exposed from gestational day (gd) 20 through postnatal day (pnd) 4; maternal exposures resumed on pnd 5. Twenty-eight weanlings/sex/group continued exposure for 12 weeks (starting on pnd 28) and were bred as described above. F0 and F1 parents and ten F1 and F2 weanlings/sex/group were necropsied, and adult reproductive organs, pituitary, liver, kidneys, and upper respiratory tract (target organs) were evaluated histologically in ten/sex/group. Adult toxicity was observed in both sexes and generations at 0.08 and 0.3 ppm, including occasional reductions in body weights and weight gain, clinical signs of toxicity at 0.08 and 0.3 ppm, and histologic changes in the nasal cavities at 0.02, 0.08, and 0.3 ppm (including rhinitis, a nonspecific response to an irritating vapor, at all concentrations). There was no reproductive toxicity, reproductive organ pathology, or effect on gestation or lactation at any exposure concentration. Postnatal toxicity and reduced body weights and weight gains during lactation occurred only in F2 litters at 0.08 and 0.3 ppm. Therefore, under the conditions of this study, a no observed adverse effect level (NOAEL) was not determined for adult toxicity; the NOAEL for reproductive toxicity was at least 0.3 ppm, and the NOAEL for postnatal toxicity was 0.02 ppm.  (+info)

The relationship between intestinal epithelial integrity and the development of intestinal disease is of increasing interest. A reduction in mucosal integrity has been associated with ulcerative colitis, Crohns disease and potentially could have links with colorectal cancer development. The Ussing chamber system can be utilised as a valuable tool for measuring gut integrity. Here we describe step-by-step methodology required to measure intestinal permeability of both mouse and human colonic tissue samples ex vivo, using the latest equipment and software. This system can be modified to accommodate other tissues. An Ussing chamber was constructed and adapted to support both mouse and human tissue to measure intestinal permeability, using paracellular flux and electrical measurements. Two mouse models of intestinal inflammation (dextran sodium sulphate treatment and T regulatory cell depletion using C57BL/6-FoxP3DTR mice) were used to validate the system along with human colonic biopsy samples.

Soil respiration is the largest C-flux component in the terrestrial carbon (C) cycle, yet in many biomes this flux and its environmental responses are still poorly understood. Several methodological techniques exist to measure this flux, but mostly there remain comparability uncertainties. For example, the closed static chamber (CSC) and the closed dynamic chamber (CDC) systems are widely used, but still require a rigorous comparison. A major issue with the CSC approach is the generally long manual gas sampling periods causing a potential underestimation of the calculated fluxes due to an asymptotic increase in headspace CO2 concentrations. However, shortening the sampling periods of the static chamber approach might provide comparable results to the closed dynamic chamber system. We compared these two different chamber systems using replicated CSC cover boxes and a Li-Cor 8100 CDC system under field conditions, and performed tests on both, mineral and peat soil. Whereas the automated CDC system ...

Beginning on GD 5, groups of 56 time-mated F0 female rats were housed in specially designed reverberation chambers and received whole-body exposures to CDMA-modulated cell phone RFR at power levels of 0 (sham control), 1.5, 3, or 6 W/kg for 7 days per week, continuing throughout gestation and lactation. Exposure was up to 18 hours and 20 minutes per day with continuous cycling of 10 minutes on and 10 minutes off during the exposure periods. There were seven exposure groups per sex, including a shared sham control and three exposure groups for each modulation. At weaning, three males and three females per litter from 35 litters were randomly selected per exposure group for continuation. Weaning occurred on the day the last litter reached PND 21, marking the beginning of the 2-year studies. Groups of 105 male and 105 female F1 offspring continued to receive whole-body exposures to CDMA-modulated cell phone RFR at the same power levels and under the same exposure paradigm, 7 days per week for up to ...

The present disclosure is directed to a novel apparatus and novel methods for the separation, characterization, and manipulation of matter. In particular, the invention combines the use of frequency-dependent dielectric and conductive properties of particulate matter and solubilized matter with the properties of the suspending and transporting medium to discriminate and separate such matter. The apparatus includes a chamber having at least one electrode element and at least one inlet and one output port into which cells are introduced and removed from the chamber. Matter carried through the chamber in a fluid stream is then displaced within the fluid by a dielectrophoretic (DEP) force caused by the energized electrode. Following displacement within the fluid, matter travels through the chamber at velocities according to the velocity profile of the chamber. After the matter has transmitted through the chamber, it exits at the opposite end of the chamber at a characteristic position. Methods according to

Glaucoma, often referred to as the silent thief of sight, can occur with no warning signs, pain or symptoms. It affects 3 million people in the United States and has caused blindness in over 120,000 people. Glaucoma cannot be cured, but if detected early can be managed to limit its effects.. Glaucoma usually occurs when there is an increase of pressure within your eye, but can occur with normal eye pressure as well. This pressure causes damage to the optic nerve, which is the weakest part of your eye, leading to decreased peripheral vision and possibly blindness.. Your eye is divided into two chambers, the anterior chamber at the front of the eye, and the posterior chamber at the back. A fluid, called the aqueous humor, is produced by the cilliary body and circulates between the two chambers to clean and nourish your eye. Once it reaches the edge of your iris it leaves the eye through an opening called the trabecular meshwork.. With glaucoma, more fluid is produced than can be removed, which ...
Cardiac catheterisation and coronary angiography can provide important information about the heart and the surrounding blood vessels supplying it.. This can help diagnose heart conditions, plan future treatments, and carry out certain procedures.. The heart has 4 chambers: the 2 small chambers at the top are called atria and the 2 larger chambers at the bottom are called ventricles. Each ventricle has 2 valves to control the flow of blood in and out of the ventricle.. Using cardiac catheterisation, your cardiologist (heart specialist) can tell how well your heart valves and chambers are working. The procedure can also provide important information about the blood pressure inside your heart.. Coronary angiography also gives video images (angiograms) that can show whether the blood vessels surrounding your heart are narrowed or blocked. You may need treatment if there are any narrow areas or blockages.. ...

A continuous flow fluid bed dryer has a dryer housing having a drying chamber and a plenum chamber located beneath the drying chamber. Moist product to be dried is introduced to the drying chamber at a product inlet and proceeds through the drying chamber to a discharge housing. A porous screen partially separates the drying chamber and the plenum chamber. Heated air is introduced into the plenum chamber which then passes through the screen to the drying chamber to dry product in the drying chamber. A shaft extends centrally through the drying chamber and is mounted for slow rotation therein. A plurality of paddles are connected to the shaft. The paddles move about a path of rotation whereby paddle ends sequentially sweep over the surface of the screen. In doing so, the paddles momentarily move product away from the screen permitting a rush of heated into the drying chamber locally fluidizing the bed and further drying the product. The product is treated very gently in the process so as to suffer

STS-91 , 6/2/1998 , Crew: 6. SUMMARY:. Main engine pressure chamber sensor failed. If it occurred later, logic error may have triggered at RTLS.. EVENT DESCRIPTION:. After the launch of STS-91 on June 2, 1998, a channel A main engine pressure chamber sensor froze. The sensor was disqualified by engine control software when the sensor exceeded allowable limits during the max Q engine throttle down sequence however the sensor remained qualified for engine redline monitoring since the reading was still within reasonableness limits / operational range for the sensor. The channel B sensor and the main engine performed nominally throughout ascent. If an engine problem had occurred, the channel B sensor would have displayed the correct information and indicated the proper corrective action. However, the channel B sensor would have been ignored due to the frozen channel A sensor.. The post-flight inspection revealed that contamination from a seal leak check caused the sensor to freeze.

There are actually two versions of the CPS 2000, and although it is true the original version is the most powerful retail super soaker, the mk2 version was only slightly less powerful. Several water guns were released 1996-2000 with comparable power. Take the CPS 2500 - it was released 2 years later in 1998 with the same pressure chamber as the mk2 CPS 2000, while adding a nozzle selector. It is my personal belief that Laramie (the company behind Super Soakers) actually shortened the pressure chamber in the mk2 to make it more reliable, not to make it safer. The mk1 longer bladder chamber (and associated higher pressure) can cause the firing valve to get stuck closed by the high pressure behind it, causing trouble as either the trigger broke or users over-pressurized and burst the bladder. Could be wrong, but you can only work with so much pressure using plastic parts. In any case, my source on the question of comparable power http://www.isoaker.com/Armoury/soaker_listing.php has a list of all ...

The health risks of crack cocaine smoking in public settings have not been well described. We sought to identify factors associated with public crack smoking, and assess the potential for a supervised inhalation facility to reduce engagement in this behavior, in a setting planning to evaluate a medically supervised crack cocaine smoking facility. Data for this study were derived from a Canadian prospective cohort of injection drug users. Using multivariate logistic regression we identified factors associated with smoking crack cocaine in public areas. Among public crack smokers we then identified factors associated with willingness to use a supervised inhalation facility. Among our sample of 623 people who reported crack smoking, 61% reported recently using in public locations. In multivariate analysis, factors independently associated with public crack smoking included: daily crack cocaine smoking; daily heroin injection; having encounters with police; and engaging in drug dealing. In sub analysis, 71%

A mobile whole-body exposure system was developed for exposing mice to concentrated ambient particulate matter smaller than 2.5 microm in mass median aerodynamic diameter (MMAD). Each 20-L exposure cage was designed to hold 9 mice within individual compartments. This allowed for transport and subsequent exposure. Airflow mixing and the potential for stagnant areas within the compartments were modeled using computational fluid dynamic modeling (CFD). CFD analysis showed no stagnant areas and good mixing throughout the exposure cage. The actual performance of the exposure system was determined for 0.5 to 2.0 microm diameter aerosols by measuring (1) uniformity of aerosol distribution and (2) particle deposition in the tracheobronchial and pulmonary regions of mice exposed in the system. A 0.6-microm MMAD (GSD=2.0) cigarette smoke aerosol was used to experimentally measure the uniformity of aerosol distribution to the nine individual compartments. The average data from three runs showed no statistically

Man-made microwave and radiofrequency (RF) radiation technologies have been steadily increasing with the growing demand of electronic appliances such as microwave oven and cell phones. These appliances affect biological systems by increasing free radicals, thus leading to oxidative damage. The aim of this study was to explore the effect of 2.45 GHz microwave radiation on histology and the level of lipid peroxide (LPO) in Wistar rats. Sixty-day-old male Wistar rats with 180 ± 10 g body weight were used for this study. Animals were divided into two groups: sham exposed (control) and microwave exposed. These animals were exposed for 2 h a day for 35 d to 2.45 GHz microwave radiation (power density, 0.2 mW/cm2). The whole-body specific absorption rate (SAR) was estimated to be 0.14 W/kg. After completion of the exposure period, rats were sacrificed, and brain, liver, kidney, testis and spleen were stored/preserved for determination of LPO and histological parameters. Significantly high level of LPO ...

MILWAUKEE, April 17 /PRNewswire/ -- Aurora St. Lukes Medical Centers new hyperbaric chamber will triple the hospitals capacity to treat patients with hyperbaric oxygen therapy and improve its regional wound care services. (Photo: http://www.newscom.com/cgi-bin/prnh/20080417/AQTH107) The 52-foot-long, 66-ton chamber, the second-largest in the U.S. and the largest in Wisconsin, will be able to treat up to 24 patients at one time. The chamber was installed today after being lifted by a huge crane and placed into the basement of Aurora St. Lukes through a 1,100-square-foot hole. Hyperbaric chambers are primarily used to help treat difficult wounds, such as diabetic foot ulcers, but also are used for carbon monoxide poisoning and a host of other medical conditions. During hyperbaric treatment, patients breathe 100 percent oxygen in a pressurized chamber. The increased oxygen in the blood stimulates small blood vessel and skin growth and helps fight infection. This new chamber will allow us to ...

Three crossover experiments (each randomized, balanced with regard to order, and separated by appropriate washout interval) will expose healthy subjects to well-characterized DEP in two-hour sessions in an inhalation chamber system mimicking ambient particulate matter from contemporary diesel engines.. First, 24 subjects will be exposed to DEP at each of three concentrations [0 (filtered air, FA), 100, or 200 µg/m3], and endothelial function will be assessed post-exposure through ultrasonographic measurement of endothelial-dependent flow-mediated vasodilation of the brachial artery, plasma markers of endothelial homeostasis (endothelin-1, ICAM-1, e-selectin, NO3-/NO2-, IL-6, and TNF-a), and markers of thrombosis associated with endothelial activation (PAI-1, D-dimer, and VWF).. Second, 10 subjects will be exposed to FA or DEP at 200 µg/m3 and then monitored intensively in the clinical research center for evidence of systemic oxidative stress using serial assessment of markers in plasma ...
The hydroxyl free radical (OH) is the major oxidizing species in the lower atmosphere. Measuring the OH concentration is generally difficult and involves elaborate, expensive, custom-made experimental setups. Thus other more economical techniques, capable of determining OH concentrations at environmental chambers, would be valuable. This work is based on an indirect method of OH concentration measurement, by monitoring an appropriate OH tracer by proton transfer reaction mass spectrometry (PTR-MS). 3-pentanol, 3-pentanone and pinonaldehyde (PA) were used as OH tracers in α-pinene (AP) secondary organic aerosol (SOA) aging studies. In addition we tested butanol-d9 as a potential universal OH tracer and determined its reaction rate constant with OH: k butanol-d9 = 3.4(±0.88) × 10 -12 cm 3 molecule -1 s -1. In order to make the chamber studies more comparable among each other as well as to atmospheric measurements we suggest the use of a chemical (time) dimension: the OH clock, which ...

Influence of A Thermogenic Dietary Supplement on Safety Markers, Body Composition, Energy Expenditure, Muscular Performance and Hormone Concentrations: A Randomized, Placebo-Controlled, Double-Blind Trial
Atmospheric chemistry is simulated in the laboratory using several types of environmental chambers; these include the batch chamber, the continuously mixed flow reactor, and the flow tube reactor. These reactors are used to study gas-phase oxidation of volatile organic compounds (VOCs) as well as the formation of secondary organic aerosol (SOA), the process by which VOCs undergo oxidation to form low-volatility products that condense onto particles. This chapter focuses on the design and characterization of environmental chambers, including: (1) radiation conditions; (2) chamber mixing state; (3) chemical blank experiments; (4) free radical generation (principally the hydroxyl (OH) radical); (5) high-versus-low-NO conditions that govern the nature of VOC oxidation chemistry; (6) deposition of particles onto chamber walls; (7) deposition of organic vapors onto chamber walls; and (8) determination of the yield of SOA. Comparison of the design and behavior of the different types of reactor is ...

Democratic lawmakers accused Gov. Arnold Schwarzenegger of hiding from the public his plans to build a new execution chamber at San Quentin State Prison in a legislative hearing Tuesday in which the governors top prison official admitted the controversial project would cost twice as much as first estimated. While a Schwarzenegger spokesman and Corrections Secretary Jim Tilton said the administration wanted to quickly build a new execution chamber to meet a federal judges concerns, lawmakers suggested a deliberate attempt to keep the project secret. Fogel listed numerous problems with capitol punishment protocol, including concerns over the drug cocktail the state used, the training of staff, and the dimly lit and cramped space inside the lime-green death chamber at San Quentin.

GÁL István, GLANT T. Tibor, MIKECZ Katalin. [INTRODUCTION - The CD44 molecule - the physiologic hialuronic acid receptor - is one of key mediators that direct the traffic of leukocytes into inflamed tissues. When applied in animal models of autoimmune arthritis, parenteral anti-CD44 antibody treatment exerts a dramatic antiinflammatory effect, but at high doses also a leukopenic effect. The goal of the present work is to elucidate the cellular basis of these phenomena. METHODS - In this study the authors used Western blot, immunoprecipitation, cell adhesion studies, flow chamber system studies (leukocyte rolling) and fluorescence microscopy following fluorescent labeling of actin cytoskeleton. RESULTS - Adhesion of CD44-expressing leukocytes to immobilized hialuronic acid does not result marked changes in cellular morphology. When incubated on immobilized anti-CD44 antibody, however, these cells spread, reorganize the actin cytoskeleton, and they adhere strongly to the surface. Studying the ...
ABSTRACT: The settlement phase of crustaceans is critical and can ultimately affect population structure. Underwater sound has been proposed as one of the most important sensory cues these animals use during this phase because it can provide direction and habitat quality information. Here, we evaluated the effect of different acoustic signals (biological and anthropogenic ones) on the orientation response of different stages (megalopae and juveniles) of four crabs (Cyrtograpsus angulatus, C. altimanus, Neohelice granulata, Leptuca uruguayensis) from a coastal lagoon. A binary choice chamber system was used and different sound sources: crustacean, fish and motorboat signals selected from recordings of the lagoon soundscape, were reproduced. Cyrtograpsus angulatus megalopae and juveniles responded positively towards crustacean signals, while juveniles responded negatively towards fish sounds. N. granulata juveniles orientated negatively towards crustacean, motorboat and fish signals. C. altimanus ...
The headline numbers from the Chambers study are derived from a fictional scenario that does not reflect any current proposals or realistic plans to achieve our climate goals.. By design, the Chamber study intentionally imposes the most stringent greenhouse gas regulations on the sectors that would face the highest costs per ton of GHG reduction.. This scenario greatly exaggerates the likely costs of any future program to achieve the economy-wide reductions set forth in the Paris Agreement, because any real program to meet those goals would be designed with cost-saving flexibility the Chamber deliberately left out.. The public-facing summary also neglects to mention that the report actually analyzed a wide range of scenarios, including one that allowed for a market-based, economy-wide approach. In that scenario, the report finds that the Paris goals can actually be achieved at much lower costs than the headline numbers suggest.. Although even that scenario still inflates costs (as well discuss ...

It is well established that strong electromagnetic fields (EMFs) can give rise to acute health effects, such as burns, which can be effectively prevented by respecting exposure guidelines and regulations. Current concerns are instead directed toward the possibility that long-term exposure to weak EMF might have detrimental health effects due to some biological mechanism, to date unknown. (1) The possible risk due to pulsed EMF at frequency 2.45 GHz and mean power density 2.8 mW/cm(2) on rat postnatal neurogenesis was studied in relation to the animal's age, duration of the exposure dose, and post-irradiation survival. (2) Proliferating cells marker, BrdU, was used to map age- and dose-related immunohistochemical changes within the rostral migratory stream (RMS) after whole-body exposure of newborn (P7) and senescent (24 months) rats. (3) Two dose-related exposure patterns were performed to clarify the cumulative effect of EMF: short-term exposure dose, 2 days irradiation (4 h/day), versus ...
Base station mobile phone antennas, which are often placed on building rooftops, represent a source of occupational exposure to electromagnetic field (EMF) to professionals who have to work in close proximity to the antennas. Examples of such workers include firemen, construction workers, janitors and many other professionals. The specific exposure systematic measurement data for antenna models for the unperturbed fields and the specific absorption rates (SARs) in close proximity (,1m) are still unavailable. The ICNIRP occupational limits consist of the basic restrictions of local SAR as an average whole-body exposure. However, in the very inhomogeneous near field of an antenna, the local exposure is more relevant than who-body average exposure. Objectives ...
Pregnant mice were assigned to the following groups: sham-exposed CDMA control mice (group 1); CDMA exposed mice (group 2); sham-exposed CDMA+WCDMA control mice (group 3); CDMA+WCDMA exposed mice (group 4). Whole-body exposures to CDMA (849 MHz) and WCDMA (1.95 GHz) at SAR of 2.0 W/kg were conducted for two 45 minute periods separated by a 15 minute interval, daily, throughout the gestation period (days 1-17). On gestation day 18, the mice were sacrificed; the uterine contents and ovaries were examined for the number of implantation sites, number of resorptions, sex and number of viable fetuses, fetal head and body size, external abnormalities, number of dead fetuses, fetal and placental weights. One-half of the live fetuses per litter were examined for visceral malformations and the other half - for skeletal malformations. Results ...

RESULTS During a flight (200 mmHg pressure decrease), excess insulin delivery of 0.623% of the cartridge volume occurred (P , 0.001, Student t test). In hypobaric chamber studies, bubbles developed in the insulin when the pressure decreased and displaced the insulin out of the cartridge. Pre-existing bubbles changed in size consistent with Boyle law. Cartridge plunger movement did not occur in normal flight conditions but did occur when catastrophic plane depressurization was mimicked. ...

PURPOSE: To analyze and to evaluate the effect of the hyperbaric hyperoxygenation in the mechanical resistance of ischemic colon of rats. METHODS: Eighty rats, distributed in four groups of 20 animals in each one, were used. In group 1 (G1), the control group, ischemia was not caused. Group 2 was submitted to the lesser degree of ischemia. Group 3 was submitted to the intermediate degree of ischemia. In group 4, a bigger degree of intestinal ischemia was provoked. Each group was divided in two sub-groups often animals each: with hyperbaric chamber (CC) and without hyperbaric chamber (SC). The animals of the four CC subgroups were placed in an experimental hyperbaric chamber in order to inhale oxygen at 100%, at two Absolute Atmospheres, for 120 minutes, for a four-day consecutive period. The animals of the four SC subgroups were kept in environment air during the five days of the experiment. All animals have been submitted to the mechanical study of the intestinal loop by the pressure test of ...

This study tested glycerol hyperhydration against water hyperhydration on the ability to reduce cardiovascular and thermal strain and improve performance when Ss ran a set distance as quickly as possible. It was hypothesized that compared with water hyperhydration, glycerol hyperhydration would result in: a) greater fluid retention, b) no differences in heart rates and core temperatures, and c) decreased run time performances. Male endurance trained runners (N = 6) completed a treadmill run in an environmental chamber at a self-selected pace, estimated to take one hour. Temperature was set at 30 C with 50% relative humidity. Beginning 2.5 hours before exercise, glycerol was given at 1.2 g/kgBW with a total fluid ingestion of 26 ml/kgBW. The placebo condition involved ingesting water of an equal amount. Runners ingested up to 500 ml during the run and were unable to see their elapsed time or chosen speed; only distance covered.. Fluid retention and time to complete the run were no different ...
Clouds in clean air have low aerosol concentration and are composed of a small number of large droplets. They do not scatter light well and are somewhat dark and translucent. Much of the Suns radiation passes through these clouds and reaches the surface.. Clouds in polluted air have much higher aerosol concentration. As aerosol concentration increases within a cloud, the water in the cloud is divided into a larger number of smaller droplets, scattering more light and becoming more reflective. These clouds appear brighter which blocks sunlight from reaching the Earths surface, shading the planet and producing net cooling. This is the cloud albedo effect. These clouds also last longer since smaller cloud droplets are less likely to fall out of the atmosphere as rain. Both effects increase the amount of radiation from the Sun that is reflected to space without reaching the surface.. According to NASA, aerosols and the clouds seeded by them reflect about 25% of the Suns radiation back to space. ...
The work presented forms part of an ongoing investigation, focusing on modeling the motion of a wall oil film present in a bearing chamber and comparison to existing experimental data. The film is generated through the impingement of oil droplets shed from a roller bearing. Momentum resulting from the impact of oil droplets, interfacial shear from the airflow, and gravity cause the film to migrate around the chamber. Oil and air exit the chamber at scavenge and vent ports. A previously reported numerical approach to the simulation of steady-state two-phase flow in a bearing chamber, which includes in-house submodels for droplet-film interaction and oil film motion, has been extended.

A method for cleaning dirty objects using cleaning fluid and rinsing fluid and an apparatus using the method. The method has consecutive steps of spraying the surface of a dirty object with high pressure spray of cleaning fluid, immersing the dirty object in an immersion chamber containing cleaning fluid, spraying additional cleaning fluid at high pressure into the immersion chamber at a location downstream from the initial location where the dirty object is immersed to turbulate cleaning fluid therein to scrub the surface of the dirty object, removing the dirty object from the immersion chamber, and spraying the surface of the dirty object with a high pressure spray of rinsing fluid.
Thats not an unreasonable idea about the altitude. If that were the case, I wonder if treating the pigs in a hypobaric chamber would do anything? I dont even know if those exist but it seems like you could use the same hyperbaric chambers that divers and mountain climbers use but instead pump the pressure in lower than 1atm (760mmHg). No clue if you could do something like that as a treatment or if it would have to be a permanent living condition. Ill have to think through the physiology on that one. It just strikes me as very reasonable. Plus, Im procrastionating today, as usual ...
