BACKGROUND Toxic lung injury may manifest itself in many different ways, ranging from respiratory tract irritation and pulmonary edema in severe cases to constrictive bronchiolitis, being a more distant consequence. It is most often the result of accidental exposure to harmful substances at work, at home, or a consequence of industrial disaster. CASE REPORT This article presents a case of tox...

Chromium (VI) is the toxic substances that are released from the electroplating and the tannery industries, it is caused serious environmental problems and is toxic to organisms. These toxic substances are effectively remediated by microorganisms such as Thiobacillus ferrooxidans. Their toxic effect is minimized by these types of microorganisms. These properties can be effectively studied in St...

Organisms have evolved the ability to tolerate toxic substances in their environments, often by producing metabolic enzymes that efficiently detoxify the toxicant. Inorganic arsenic is one of the most toxic and carcinogenic substances in the environment, but many organisms, including humans, metabolise inorganic arsenic to less toxic metabolites. This multistep process produces mono-, di-, and ...

Urban stormwater is a source of persistent, mobile and toxic substances, however the risk for water resources unknown.

Palytoxin, one of the most toxic non-peptide substances, formed an associated dimer of 5 nm length in aqueous solution.

Bacteria can adapt to various environmental factors such as temperature, pressure, ions, nutrients and toxic substances by modifying their membranes to maintain them in a fluid state. These modifications within the cytoplasmatic membrane particularly result from changes in the fatty acid composition and interaction between proteins and lipids. Fatty acids, mainly phospholipid fatty acids, play ...

Several drugs and toxic substances can cause muscular abnormalities and are frequent causes of acquired myopathies. We present a series of 32 patients, predominance of young adult patients, diagnosed with toxic myopathy. The most common substances inducing myopathy were corticosteroids (56.2%) followed by the propoxyphene, neuroleptics, zidovudine and drug-induced hypokalemia. The investigation...

In a bid to provide better protection for children's health, U.S. Senators Barbara Boxer (D-California) and Frank Lautenberg (D-New Jersey) introduced the Children's Environmental Protection Act (CEPA), on 24 May 1999. CEPA is an amendment to the Toxic Substances Control Act of 1976 and seeks to protect children from exposures to hazardous substances such as toxic air pollutants and pesticides ...

Olfactory cells receive numerous odorants including toxic substances. To avoid complete loss of the olfactory function by toxic odorants, continuous neurogenesis of olfactory cells occurs even at adulthood. Newly generated olfactory neurons extend their axons to the olfactory bulb. Various molecules including polypeptides, proteins, polynucleotides, virus, and cells administrated intranasally h...
