TY - JOUR. T1 - Physiological responses of three species of unionid mussels to intermittent exposure to elevated carbon dioxide. AU - Hannan, Kelly D.. AU - Jeffrey, Jennifer D.. AU - Hasler, Caleb T.. AU - Suski, Cory D.. PY - 2016. Y1 - 2016. N2 - Freshwater systems are at risk owing to increasing carbon dioxide (CO2) levels, and one of the possible reasons for these elevations is the deployment of non-physical fish barriers to prevent invasive fish movements. Carbon dioxide barriers have the potential to create short, chronic and intermittent exposures of CO2 for surrounding freshwater biota. Although intermittent exposures to a stressor may be more ecologically relevant, the majority of laboratory tests use chronic or short-term time periods to determine how organisms will respond to an environmental stressor. Measurements of the physiological responses of three species of unionid mussel, giant floaters (Pyganodon grandis), threeridge (Amblema plicata) and plain pocketbook (Lampsilis ...

Ann Arbor, MI, April 8, 2014 /3BL Media/ - While preventable, carbon monoxide poisoning is a serious and sometimes fatal condition. Large weather events, such as snowstorms and heavy storms that cause power outages, can lead to an increase in the number of reported carbon monoxide exposures. Researchers from Hartford Hospital in Hartford, Connecticut explored the link between these major storms and the rise in carbon monoxide exposure cases. They found that portable generators were the most common source of carbon monoxide exposure after storms which resulted in power losses; car exhaust was the most frequent source of exposure after heavy snowstorms. Their findings are published in the May issue of the American Journal of Preventive Medicine.. In 2011, 12,136 unintentional exposures were reported to U.S. Poison Control Centers. Carbon monoxide is an odorless, colorless, and tasteless gas that can build up to dangerous levels in unventilated areas. Symptoms of carbon monoxide poisoning include ...

Carbon monoxide is a dangerous gas that has no color or odor. There is no way for you to tell it is in your home in Cheyenne, WY, unless you have a carbon monoxide detector. Exposure to carbon monoxide can quickly cause serious health effects, and prolonged exposure to carbon monoxide could be deadly. Understanding how carbon monoxide can get into your home in Cheyenne and recognizing the symptoms of carbon monoxide poisoning allow you to take prompt actions to protect your health. How Carbon Monoxide Gets Into Your Home Carbon monoxide gets into your home if fuel isn't fully burned. A faulty furnace, an oven or a water heater could cause it. Carbon monoxide is also in the exhaust of diesel, propane and gasoline engines as well as that of gas and charcoal grills. Symptoms of Carbon Monoxide Poisoning Symptoms of carbon monoxide poisoning include: Headache Fatigue Nausea Loss of balance Memory and vision problems Unconsciousness Pregnant women, babies and the elderly are more susceptible to ...

The Bacteriological Code deals with the nomenclature of prokaryotes. This may include existing names (the Approved Lists of Bacterial Names) as well as new names and new combinations. In this sense the Code is also dealing indirectly with taxonomic opinions. However, as with most codes of nomenclature there are no mechanisms for formally recording taxonomic opinions that do not involve the creation of new names or new combinations. In particular, it would be desirable for taxonomic opinions resulting from the creation of synonyms or emended descriptions to be made widely available to the public. In 2004, the Editorial Board of the International Journal of Systematic and Evolutionary Microbiology (IJSEM) agreed unanimously that it was desirable to cover such changes in taxonomic opinions (i.e. the creation of synonyms or the emendation of circumscriptions) previously published outside the IJSEM, and to introduce a List of Changes in Taxonomic Opinion [Notification of changes in taxonomic opinion

Oral mucosal melanoma is a rare disease with a relatively poor prognosis. Carbon ion radiotherapy has been shown to be effective against radiotherapy-resistant tumors owing to its excellent dose concentration and high biological effect. Our patient was a 66-year-old Japanese man with oral mucosal melanoma of his right maxillary gingiva (T4aN0M0). He received carbon ion radiotherapy at 57.6 Gy (relative biological effectiveness) in 16 fractions for 4 weeks. Concomitant chemotherapy (dacarbazine + nimustine + vincristine) was administered at the same time as carbon ion radiotherapy initiation. Two courses of adjuvant chemotherapy were given after carbon ion radiotherapy. Although he experienced grade 2 acute oral mucositis, his symptoms improved within a few weeks of undergoing carbon ion radiotherapy. He was alive at the time of reporting, 35 months after treatment, without any recurrence. Late toxicity has not been observed. Carbon ion radiotherapy for oral mucosal melanoma resulted in a good local

AU - Togtema, Arnoud. AU - Gouveia, Joao. AU - Yesil-Celiktas, Ozlem. PY - 2018/5/1. Y1 - 2018/5/1. N2 - In bio-based industries, Botryococcus braunii is identified as a potential resource for production of hydrocarbons having a wide range of applications in chemical and biopolymer industries. For a sustainable production platform, the algae cultivation should be integrated with downstream processes. Ideally the algae are not harvested, but the product is isolated while cultivation and growth is continued especially if the doubling time is slow. Consequently, hydrocarbons can be extracted while keeping the algae viable. In this study, the effects of pressure on the viability of B. braunii cells were tested hydrostatically and under supercritical CO2 conditions. Viability was determined by light microscopy, ...

CO and 4 of the CORMs (ALF 153, 157, 436 and CORM-2) increased cGMP levels in smooth muscle cells, while the rest of the compounds failed to alter cGMP production. The CORM-stimulated increase was minor (50-300% over basal) compared to the effects seen with the NO-donor, SNP (at least 100-fold). CORM-3, a widely used CORM, decreased basal cGMP levels in RASMC. Interestingly, CO and CORMs modestly reduced SNP-stimulated cGMP formation in RASMC. The inactive forms of CORMs (compounds lacking the ability to liberate CO) did not affect SNP-induced cGMP accumulation. CORMs also reduced bradykinin-stimulated cGMP levels in endothelial-smooth muscle co-cultures. In sGC activity assays using purified recombinant human sGC, CORMs were ineffective in stimulating cGMP production. However, CORMs blocked up to 80% of DEA-NO-induced sGC activity. ...

Recent investigations of Lamiaceae family essential oil storage have shown that most of the oil is found in peltate glandular trichomes on the leaf surface. The effect of supercritical CO2 on the peltate glands was investigated by Scanning Electron Microscopy. It was observed that exposure to supercritical CO2 led to disruption of the peltate glands and essential oil release. This phenomenon was used as a basic hypothesis of the mathematical model of the supercritical fluid extraction with CO2. The model was applied to simulate basil, rosemary, marjoram and pennyroyal supercritical CO2 extraction on the existing experimental data. An average deviation from the experimental data was less than 0.83%. The ...

Production of AmpC and extended spectrum beta-lactamases among urinary isolates has created a serious problem to the successful management of the urinary tract infection. The main purpose of this study was to determine the rates of the extended spectrum beta-lactamase (ESBL) production and AmpC beta-lactamase (ABL) production among urinary isolates. Among total 564 urinary isolates, 514 (91.1%) were gram negative bacilli and 50 (8.9%) were gram positive cocci. E. coli (76.1%) was the most common bacteria isolated. Staphylococcus aureus (6.7%) was the predominant gram positive bacteria isolated. 35 (6.8%) of the 514 gram negative bacilli were ESBL producers. Similarly, 14 (2.7%) of the gram negative bacilli were ABL producers. Only one isolate was ESBL and ABL co-producer. Highest rate of susceptibility of gram negative bacteria was seen toward amikacin (97.3%) followed by imipenem (94.4%). Similarly, highest rate of susceptibility among gram positive cocci was seen toward vancomycin (100%) followed by

Carbon dioxide insufflation in esophageal endoscopic submucosal dissection reduces mediastinal emphysema: A randomized, double-blind, controlled trial

Agricultural systems rely on healthy soils and their sustainability requires understanding the long-term impacts of agricultural practices on soils, including microbial communities. We examined the impact of 17 years of land management on soil bacterial communities in a New Zealand randomized-block pasture trial. Significant variation in bacterial community structure related to mowing and plant biomass removal, while nitrogen fertilizer had no effect. Changes in soil chemistry and legume abundance described 52% of the observed variation in the bacterial community structure. Legumes (Trifolium species) were absent in unmanaged plots but increased in abundance with management intensity; 11% of the variation in soil bacterial community structure was attributed to this shift in the plant community. Olsen P explained 10% of the observed heterogeneity, which is likely due to persistent biomass removal resulting in P limitation; Olsen P was significantly lower in plots with biomass removed (14 mg ...

Introduction: The present study was undertaken to determine the prevalence of non-fermenting gram negative bacilli and antibiogram of Pseudomonas aeruginosa and Acinetobacter baumannii. Materials and Methods: Conventional bacteriological methods were used for identification non fermenting gram negative bacilli and susceptibility testing was performed with the help of the Kirby-Bauer disc diffusion method. Results: A total 195 non fermenting gram negative bacilli were isolated during the study period. Pseudomonas aeruginosa and Acinetobacter baumannii isolates represent 89.23% of all isolated bacteria. Therefore, antibiotic resistance rates were performed specifically against these two bacteria. P. aerurginosa showed good sensitivity to imipenem(94.29%) followed by amikacin(86.67%) and piperacillin/tazobactum(68.57%). A. baumannii showed good sensitivity to imipenem(82.61%) followed by amikacin(76.81%). Conclusion: P. aeruginosa and A. baumannii were the most common NFGNB isolated in our study. ...

The isoprene production is calculated as a function of electron transport-limited photosynthesis, intercellular and atmospheric carbon dioxide concentration, and canopy temperature. The vegetation biophysics module computes the photosynthetic uptake of carbon dioxide coupled with the transpiration of water vapor and the isoprene emission rate at the 30 min physical integration time step of the global chemistry-climate model. In the model, the rate of carbon assimilation provides the dominant control on isoprene emission variability over canopy temperature. A control simulation representative of the present-day climatic state that uses 8 plant ...

The NIH Human Microbiome Project (HMP) has been carried out over ten years and two phases to provide resources, methods, and discoveries that link interactions between humans and their microbiomes to health-related outcomes. The recently completed second phase, the Integrative Human Microbiome Project, comprised studies of dynamic changes in the microbiome and host under three conditions: pregnancy and preterm birth; inflammatory bowel diseases; and stressors that affect individuals with prediabetes. The associated research begins to elucidate mechanisms of host-microbiome interactions under these conditions, provides unique data resources (at the HMP Data Coordination Center), and represents a paradigm for future multi-omic studies of the human microbiome. Over ten years, the Human Microbiome Project has provided resources for studying the microbiome and its relationship to disease; this Perspective summarizes the key achievements and findings of the project and its relationship to the broader field.

AU - Bugedo, Guillermo. AU - Adams, Alexander B.. AU - Bliss, Peter L.. AU - Marini, John J. PY - 1999/8. Y1 - 1999/8. N2 - BACKGROUND: Tracheal gas insufflation (TGI) reduces arterial carbon dioxide tension (P(aCO2)) when used in conjunction with mechanical ventilation, but antegrade TGI flow increases intrinsic positive end- expiratory pressure (auto-PEEP) or end-expiratory lung volume (EELV). Tracheal gas exsufflation (TGE) might reduce TGI-elevated EELV while retaining the CO2 elimination effects of TGI. METHODS: An apparatus was designed to control TGI and/or TGE during selected portions of expiration. The first phase of the study examined the general effects of expiratory TGI and TGE on EELV and CO2 elimination in a mechanical test lung. In the second phase, effects on normal physiology were tested in ...

CO fire detectors are electronic detectors used to indicate the outbreak of fire by sensing the level of carbon monoxide in the air. Carbon monoxide, usually known by its chemical formula CO, is a poisonous gas produced by combustion. They are not the same as CO detectors used for home safety which are used to protect residents against carbon monoxide produced by incomplete combustion in appliances such as gas fires or boilers.. CO fire detectors use the same type of sensor but are more sensitive and respond more quickly.CO detectors have an electrochemical cell, which senses carbon monoxide, but not smoke or any other combustion products. The cells do not require much power, so the detectors can be made electrically compatible with ordinary smoke and heat detectors. As fire detectors they are effective but only for certain types of fire. Deep-seated, smouldering fires produce carbon monoxide, which can be detected some distance from the seat of the fire. For this type of fire a CO fire detector ...

A novel electrochemical sensor for sensitive detection of doxepin was prepared, which was based on a glassy carbon electrode modified with poly(4-aminobenzoic acid)/multi-walled carbon nanotubes composite film [poly(4-ABA)/MWNTs/GCE]. The sensor was characterized by scanning electron microscopy and electrochemical methods. It was observed that poly(4-ABA)/MWNTs/GCE showed excellent preconcentration function and electrocatalytic activities towards doxepin. Under the selected conditions, the anodic peak current was linear to the logarithm of doxepin concentration in the range from 1.0 ´ 10−9 to 1.0 ´ 10−6 M, and the detection limit obtained was 1.0 × 10−10 M. The poly(4-ABA)/MWNTs/GCE was successfully applied in the measurement of doxepin in commercial pharmaceutical formulations, and the analytical accuracy was confirmed by comparison with a conventional ultraviolet spectrophotometry assay.

We used stable carbon isotopes to analyse individual variation in arctic fox diet. We extracted collagen from bones (the lower jaw), and measured stable carbon isotopes. The foxes came from three different localities: Iceland, where both microtines and reindeer are rare; west Greenland, where microtines are absent; and Sweden, where seat analyses showed the primary food to be microtine rodents and reindeer. The Icelandic samples included foxes from both coastal and inland habitats, the Swedish sample came from an inland area, and the Greenland sample from coastal sites. The spatial variation in the isotopic pattern followed a basic division between marine and terrestrial sources of protein. Arctic foxes from inland sites had delta(13)C values of -21.4 (Ice land) and -20.4 parts per thousand (Sweden), showing typical terrestrial values. Coastal foxes from Greenland had typical marine Values of -14.9 parts per thousand, whereas coastal foxes from Iceland had intermediate values of -17.7 parts per ...

Tropical forests are vital global reservoirs of biodiversity and carbon (C). Deforestation and degradation of these ecosystems greatly threatens their capacity to provide crucial ecosystem functions and services, by altering complex plant-soil interactions and biogeochemical cycles underpinned by soil microbes. Forest disturbance is accelerating in Southeast Asia, through widespread selective logging (SL) and forest conversion to oil palm plantation (OP). This has major implications for soil microbial communities and functions, although effects of tropical forest disturbance on belowground biodiversity and the resistance and resilience of soil microbial nutrient and C-cycling are unresolved. The potential to restore soil microbial communities and essential functions is also largely unknown. The aim of this thesis was to evaluate impacts of tropical forest modification (degradation, conversion and restoration) on soil microbial community attributes, and implications for ecosystem biogeochemical ...

2-(2',4'-Dibromophenoxy)-4,6-dibromophenol isolated from the marine sponge Dysidea granulosa (Bergquist) collected off the coast of Lakshadweep islands, Indian Ocean, exhibited potent and broad spectrum in-vitro antibacterial activity, especially against methicillin resistant Staphylococcus aureus (MRSA), methicillin sensitive Staphylococcus aureus (MSSA), vancomycin resistant Enterococci (VRE), vancomycin sensitive Enterococci (VSE) and Bacillus spp. Minimal inhibitory concentration (MIC) was evaluated against 57 clinical and standard strains of Gram positive and Gram negative bacteria. The observed MIC range was 0.117-2.5 μg/mL against all the Gram positive bacteria and 0.5-2 μg/mL against Gram negative bacteria. The in-vitro antibacterial activity observed was better than that of the standard antibiotic linezolid, a marketed anti-MRSA drug. The results establish 2-(2',4'-dibromophenoxy)-4,6-dibromophenol, as a potential lead molecule for anti-MRSA and anti-VRE drug development.

During the study period, 1032 isolates of Gram-negative bacilli that had been collected from patients with hepatobiliary infections were ...

Metal insulator silicon carbide field-effect transistor sensors, metal-oxide sensors, and a linear Lambda sensor in an electronic nose was used to measure on-line in hot flue gases from a boiler. Flue gas from a 100-MW pellets-fuelled boiler has been used to feed the experimental setup. Several reference instruments, which measure the flue gases in parallel to the sensor array, are connected to the electronic nose. Data was collected during six weeks and then evaluated. Using principal component analysis as the data evaluation method, different operating modes for the boiler have been identified in the data set. The different modes could be described in terms of high or low O 2 and CO concentration. Furthermore, we have shown that it seems possible to use a sensor array to determine the operating mode of the boiler and, by partial least-squares models, measure the CO concentration when the boiler operates in its optimum mode.. ...

Introduction: The inhalation of tobacco smoke can substantially raise the level of carboxyhemoglobin in the blood. Determination of the level of carboxyhemoglobin and methemoglobin can identify patients with increased risk for development of postoperative pulmonary complications. Material and Methods: Thirty patients scheduled for elective urologic surgery under general endotracheal anesthesia were allocated in two groups (n = 15 each). The study group comprised patients who were smoking cigarettes or tobacco pipe, while the control group included non-smokers. In both group's carboxyhemoglobin and methemoglobin levels were determined preoperatively, after preoxygenation, and one hour after completing the anesthesia. Postoperative pulmonary complications were assessed and recorded during the period of hospitalization.Results: The average values of carboxyhemoglobin between the two groups were statistically significantly different. Postoperative carboxyhemoglobin was higher in smokers compared to

For high power CO2 lasers the discharge tube consists of a number of tubes placed in a parallel configuration with ar-rangement for optical folding of light through back and forth reflections. The slow axial flow lasers can produce a maximum output of about 500 watts be-cause 75 - 90% of the discharge energy is dissipated in the gas resulting in its overheating and decomposition with consequential fall in output. For higher output the gas is driven through the laser tube at a high speed by a blower; this reduces the heat loss to the walls to a negligible amount. While a slow axial flow laser will deliver about 50 - 70 watts per meter of laser cavity, the fast axial flow laser can generate upto 600 watts per meter. Gas Laser Operation: In a carbon dioxide laser the CO2 molecules are vibrationally excited by an electric discharge across the laser cavity. The direct vibrational excitation of CO2 by an electric discharge is inefficient. However, N2 accepts energy effectively from the discharge and ...

Patients with complicated urinary tract infections (cUTIs) frequently receive broad-spectrum antibiotics. We aimed to determine the prevalence and predictive factors of multidrug-resistant gram-negative bacteria in patients with cUTI.

Solid acid catalysts were synthesized from macroalgae Sargassum horneri via hydrothermal carbonization followed by sulfuric acid sulfonation. A three-variable Box-Behnken design and optimization was used to maximize surface acidity. The optimal preparation conditions were found to be at the carbonization temperature of 217 °C, the carbonization time of 4.6 hours and the sulfonation temperature of 108.5 °C. Under these conditions, the highest surface acidity achieved was 1.62 mmol g-1. Physical and chemical properties of prepared solid acid catalyst were characterized by powder X-ray diffraction (PXRD), Fourier transform infrared (FTIR) spectroscopy, and elemental analysis. The results proved the grafting of -SO3H groups on an amorphous carbon structure. The catalyst activity was evaluated by the esterification of oleic acid with methanol. The sample prepared achieved 96.6% esterification yield, which was higher than the 86.7% yield achieved by commercial Ambersyst-15 under the same reaction ...

Background: Out-of-hospital cardiac arrest (OHCA) remains a major public health issue. Several studies have found that an increased level of ambient particulate matter (PM) smaller than 2.5 microns (PM2.5) is associated with an increased risk of OHCA. We investigated the relationship between air pollution levels and the incidence of OHCA in Perth, Western Australia.Methods: We linked St John Ambulance OHCA data of presumed cardiac aetiology with Perth air pollution data from seven monitors which recorded hourly levels of PM smaller than 2.5 and 10 microns (PM2.5/PM10), carbon monoxide (CO), sulfur dioxide (SO2), nitrogen dioxide (NO2) and ozone (O3). We used a case-crossover design to estimate the strength of association between ambient air pollution levels and risk of OHCA.Methods: We linked St John Ambulance OHCA data of presumed cardiac aetiology with Perth air pollution data from seven monitors which recorded hourly levels of PM smaller than 2.5 and 10 microns (PM2.5/PM10), carbon monoxide ...

In this study, kecombrang flowers was extracted with non polar (hexane), semipolar (ethil acetate) and polar (ethanol) solvent. The result revealed that ethil acetat and ethanol extracts inhibited 7 bacteria, i.e : spore forming bacteria (Bacillus cereus), Gram positive bacteria (Staphylococcus aureus) and (Listeria monocytogenes), Gram negative bacteria (Salmonella typhimurium, Aeromonas hydrophila and Escherichia coli), spoilage bacteria (Pseudomonas aeruginosa) but did not inhibit Lactobacillus plantarum. The hexane extract did not show antimicrobial activity. On well diffusion test, ethil acetate developed clear zones of 12.3 – 27.3 mm (diameters) and this was higher than ethanol extract 11.0-15.4 mm (diameters). The MIC (minimum inhibitory concentration) of ethil acetate and ethanol extract against the seven bacteria were 3-13 mg/ml ...

Household air pollution (HAP) contributes to the global burden of disease. Our primary purpose was to determine whether HAP exposure was associated with reduced lung function and respiratory and non-respiratory symptoms in Belizean adults and children. Our secondary purpose was to investigate whether lifestyle (physical activity (PA) and fruit and vegetable consumption (FV)) is associated with reported symptoms. Belizean adults (n = 67, 19 Male) and children (n = 23, 6 Male) from San Ignacio Belize and surrounding areas participated in this cross-sectional study. Data collection took place at free walk-in clinics. Investigators performed initial screenings and administered questionnaires on (1) sources of HAP exposure; (2) reported respiratory and non-respiratory symptoms and (3) validated lifestyle questionnaires. Participants then performed pulmonary function tests (PFTs) and exhaled breath carbon monoxide (CO). There were no significant associations between HAP exposure and pulmonary function in

Bacterial Diseases. Enteric Septicemia of Catfish (ESC) is an important infectious bacterial disease of farm-raised channel catfish. The causative agent of ESC is a gram-negative bacterial species, Edwardsiella ictaluri. While channel catfish are the most susceptible to infection, most other catfish species are also susceptible. ESC was first recognized in pond-raised channel catfish in 1976. Treatments include early intervention with approved antibiotics, restricting feed, and vaccination. While it is unclear whether these treatments are directly responsible, catfish operations are reporting decreased losses of foodfish and fry/fingerlings due to ESC.. Columnaris disease is one of the most common diseases of warmwater fish and infects at least 36 species of cultured and wild fish. While the causative bacterium has been renamed and reclassified many times, the current name is Flavobacterium columnare.. Although columnaris disease is often considered a secondary infection following periods of ...
