The purpose of this study is to investigate whether airborne exposure to endotoxins, hydrogen sulphide (H2S), and inhalable particles negatively impacts the respiratory system and inflammatory blood proteins in sewage plant and sewer net system workers and, further, to determine dose-response associations between exposure and health outcomes.

Placental infection induces increased levels of pro-inflammatory cytokines, which have been implicated in the pathogenesis of preterm labor. Endotoxin tolerance is a phenomenon in which exposure to a ...
Exposure to endotoxin occurs environmentally and occupationally. There are several differences between them in terms of the variety and severity of health outcomes, possible exposed groups and type an...
House endotoxin and ambient air pollution are risk factors for asthma; however, the effects of their co-exposure on asthma are not well characterized.
Novel graphene oxide (GO)-based adsorbent embedded with epichlorohydrin (ECH) as a coupling agent and dimethylamine (DMA) as a ligand (GO-ECH-DMA) were prepared and employed for endotoxin removal from...
In this study, the activities of hydrogen sulphide (HS) oxidation and nitrate (N-NO) reduction by three pure and mixed strains of nitrate-reducing, sulphide oxidizing bacteria (NR-SOB) were determined...
The purpose of this study will be to determine whether there is any role for measuring Hydrogen Sulphide (H2S) in the exhaled breath in terms of management of the patient with asthma. ...
The purpose of this study is to determine the inflammatory response to 20,000 endotoxin units (EU) of CCRE (Clinical Center Reference Endotoxin) inhalation in a cohort of healthy volunteer...
The aim of the study is to isolate the direct effects of endotoxin on glucose, lipid and protein metabolism. Eight healthy volunteers are enrolled. The hypothesis is that endotoxin will in...
The purpose of this study is to determine the range of neutrophil response (influx of PMNs to the airways as determined in sputum) after inhalation of CCRE (20,000 EU).
This project aims to characterize the independent effect of domestic endotoxin exposure on health status, as well as pulmonary and systemic inflammation, in former smokers with COPD. Posit...
Sensitive method for detection of bacterial endotoxins and endotoxin-like substances that depends on the in vitro gelation of Limulus amebocyte lysate (LAL), prepared from the circulating blood (amebocytes) of the horseshoe crab, by the endotoxin or related compound. Used for detection of endotoxin in body fluids and parenteral pharmaceuticals.
Short-lived radioactive decay products of radon that include 216-Po, 214-Pb, 214-Bi, and 214-Po. They have an effective half-life of about 30 minutes and are solids that can deposit on the bronchial airways during inhalation and exhalation. This results in exposure of the respiratory airways to alpha radiation and can lead to diseases of the respiratory system, including lung cancer. (From Casarett and Doull's Toxicology, 4th ed, p740)
Waste products which, upon release into the atmosphere, water or soil, cause health risks to humans or animals through skin contact, inhalation or ingestion. Hazardous waste sites which contain hazardous waste substances go here.
A process of waste disposal involving the conversion of green waste (i.e. leaves, organic matter, food waste, manure) into soil-enhancing matter.
Sites that receive and store WASTE PRODUCTS. Some facilities also sort, process, and recycle specific waste products.
Asthma COPD Cystic Fibrosis Pneumonia Pulmonary Medicine Respiratory Respiratory tract infections (RTIs) are any infection of the sinuses, throat, airways or lungs. They're usually caused by viruses, but they can also ...
