Excess nutrients, such as fat and sugar, do not just pack on the pounds but can push some cells in the body over the brink. Unable to tolerate this “toxic” environment, these cells commit suicide. Now, scientists at Washington University School of Medicine in St. Louis have discovered three unexpected players that help a cell […]
In April 2009, researchers at UCLA announced they had discovered a link between Parkinson’s disease and two chemicals commonly sprayed on crops to fight pests. That epidemiological study did not examine farmers who constantly work with pesticides but people who simply lived near where farm fields were sprayed with the fungicide maneb and the herbicide […]
Infants and very young children who are exposed to anesthesia may experience higher rates of learning disabilities and cognitive difficulties than children who are not exposed to anesthesia, according to research and emerging data presented during the SmartTots: Pediatric Anesthesia Neurotoxicity panel at the International Anesthesia Research Society annual meeting in Vancouver, B.C.
No one knows the cause of most cases of Alzheimer’s disease, Parkinson’s disease, and other neurodegenerative disorders. But researchers have found that certain factors are consistently associated with these debilitating conditions. One is DNA damage by reactive oxygen species, highly destructive molecules usually formed as a byproduct of cellular respiration. Another is the presence of […]
Ecstasy – the illegal “rave” drug that produces feelings of euphoria and emotional warmth – has been in the news recently as a potential therapeutic. Clinical trials are testing Ecstasy in the treatment of post-traumatic stress disorder (PTSD). But headlines like one in Time magazine’s health section in February – “Ecstasy as therapy: have some […]
To reduce the toxicity of cigarette smoke, tobacco companies have introduced “harm reduction cigarettes,” often marketed as safer than conventional brands. But stem cell scientists at the University of California, Riverside have found that even sidestream smoke (which burns off the tip of a cigarette) from harm reduction cigarettes impairs growth of human embryonic stem […]
Researchers at the National Institutes of Health and other institutions have found that exposure to lead in childhood may delay the onset of puberty in young girls, with higher doses increasing the chance for later maturation. Their findings appear in Environmental Health Perspectives, published by the National Institute of Environmental Health Sciences.
