An international group of toxicologists, which includes experts from the Far Eastern Federal University (FEFU), pointed out that unicellular microalgae, the most common microorganisms on Earth and an important part of the food chain for more developed organisms, serve as an effective biomarker of environmental pollution. They quickly respond to chemical contamination of the environment by oxidative stress. The study was published in Current Opinion in Toxicology.
Children living in homes with all vinyl flooring or flame-retardant chemicals in the sofa have significantly higher concentrations of potentially harmful semi-volatile organic compounds (SVOCs) in their blood or urine than children from homes where these materials are not present, according to new Duke University-led research. The researchers presented their findings Feb. 17 at the annual meeting of the American Association for the Advancement of Science in Washington, D.C.
A team of researchers from SDSU has found silicone wristbands to be an effective way to measure children's exposure to secondhand smoke.
The study of natural toxins and their derivatives may help in the development of medicines to treat diseases like cancer and osteoarthritis, says coordinator of the Center of Excellence in New Target Discovery.
Scientists of the Far Eastern Federal University (FEFU), working as part of an international toxicologists' team, studied fur samples of the wild terrestrial mammals in Primorye, Russian Far East. All samples contained persistent organic pollutants (POPs) which are resistant to decomposition, tend to accumulate in body tissues and are potentially risky for human and animal health. Some of them are prohibited by the Stockholm Convention. The research outcome was published in Environmental Science and Pollution Research.
University of Colorado Cancer Center study shows cancer-promoting changes in lung cells as soon as 30 minutes after exposure to low-molecular weight PAHs, adding further evidence that regulators may be underestimating the risk of these compounds.
If button cells are swallowed, they can get stuck in the esophagus and severely damage the mucosa. The Assessment of Intoxications committee of the German Federal Institute for Risk Assessment (BfR) therefore recommends particular care. In the last 10 years, several hundreds of cases involving the swallowing of button cell batteries have been reported to the BfR by hospitals and poison information centers. The health damage is caused above all by the discharge current of the batteries.
A research team at Harvard University has now removed a major barrier for the use of kidney organoids as a tool to model kidney diseases, test drug toxicities and eventually for the creation of organ replacements, the lack of a pervasive blood vessel system (vasculature). The team solved this problem with a powerful new approach that exposes stem cell-derived kidney organoids to fluidic shear stress and thus enables them to vascularize and mature further than they could before.
Microbiologist Dr. Jason Huntley identified groups of bacteria in Lake Erie that degrade microcystin and can be used to naturally purify water.
A new study that directly compares new heated tobacco devices with vaping and traditional cigarettes shows that all three are toxic to human lung cells.
