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.
Cell Study Sheds Light on Damage Caused by Aging
Some of the damaging cell effects linked to aging could be prevented by manipulating tiny parts of cells, a study shows. Scientists have shed light on how the harm caused by senescence – a vital cell process that plays a key role in diseases of aging – could be controlled or even stopped.
Gut Bacteria May Have a Direct Association With Dementia
Researchers studying the population of bacteria and microbes in the intestines, known as gut microbiota, have found these "bugs" impact risks for diseases of the heart and more.
Scientists Discover Cellular Process That Stops Cancer Before it Starts
Scientists studying the relationship of telomeres to cancer made a surprising discovery: a cellular recycling process called autophagy – generally thought of as a survival mechanism – actually promotes the death of cells, thereby preventing cancer initiation.
Aspirin and Ibuprofen Improve Survival in Head and Neck Cancer
Regular use of common non-steroidal anti-inflammatory drugs (NSAIDs) such as aspirin and ibuprofen significantly improves survival for a third or more patients with head and neck cancer, improving overall five-year survival rate from 25 percent to 78 percent.
Stroke Drug May Prevent Alzheimer's Disease
A drug currently being developed to treat stroke patients could also prevent Alzheimer's disease. Researchers report that the compound protects the brains of mice with Alzheimer's-like symptoms, reducing the buildup of toxic peptides and preventing memory loss.
