Water bottles may claim to be BPA-free and personal care products may declare that phthalates are not among their ingredients, but assurances are not enough. According to a study in Journal of Exposure Science and Environmental Epidemiology, people may be exposed to chemicals in their diets, even if their meals are organic and foods are prepared, cooked and stored in non-plastic containers.

Too much antibiotic can decimate the normal intestinal microbiota, which may never recover its former diversity. That, in turn, renders the GI tract vulnerable to being colonized by pathogens. Now researchers from Memorial Sloan-Kettering Cancer Center, New York, NY, and Centro Superior de Investigación en Salud Pública, Valencia, Spain, show that reintroducing normal microbial diversity largely eliminated vancomycin-resistant enterococci (VRE) from the intestinal tracts of mice. The investigators showed further that the findings may apply to humans.
Researchers at Moffitt Cancer Center studied patients with metastatic gastric cancer and found that those who have both surgery and radiation have better survival than those who receive one or no form of treatment.
The study appeared in an online issue of Cancer.
"There were an estimated 21,000 new cases of gastric cancer in the United States in 2010 and 11,000 deaths from the disease," said Ravi Shridhar, M.D., Ph.D., of the Radiation Oncology Department at Moffitt. "Most gastric cancers are diagnosed at advanced stages, when surgery may not be an option."
It's common knowledge that a child who misses a meal can't concentrate in school. But what happens years down the road? Does that missed meal have any bearing on health in adulthood?
A new University of Nebraska-Lincoln study shows that missed meals in childhood can be linked to experiencing pain and depression in adulthood. Depression and chronic pain are experienced by 44 percent of working-aged adults and the study shows a correlation between childhood conditions and pain and depression in adulthood.
CAMBRIDGE, MA -- Inspired by a chemical that fungi secrete to defend their territory, MIT chemists have synthesized and tested several dozen compounds that may hold promise as potential cancer drugs.
Leipzig/Halle. Pregnant women should avoid taking vitamin D supplements. Substitution appears to raise the risk of children developing a food allergy after birth. This was the conclusion drawn from a new survey carried out by the Helmholtz Centre for Environmental Research and the Martin Luther University in Halle-Wittenberg in Germany which was published in the February issue of the medical journal Allergy.
A team led by Dr. Marie-Josée Hébert from the University of Montreal Hospital* Research Centre (CRCHUM) has discovered a new cause of organ rejection in some kidney transplant patients. Her team has identified a new class of antibodies – anti-LG3 – which when activated lead to severe rejection episodes associated with a high rate of organ loss. This discovery, which holds promise for organ recipients, was published in the online version of the American Journal of Transplantation.
Preclinical, laboratory studies suggest a novel immunotherapy could potentially work like a vaccine against metastatic cancers, according to scientists at Virginia Commonwealth University Massey Cancer Center. Results from a recent study show the therapy could treat metastatic cancers and be used in combination with current cancer therapies while helping to prevent the development of new metastatic tumors and train specialized immune system cells to guard against cancer relapse.
A Case Western Reserve University professor has found that young people addicted to alcohol and drugs can increase their chances of recovery by helping others.
In 2010, Maria Pagano, PhD, found that adults who became involved in Alcoholics Anonymous-related service-type work were more likely to stay sober 10 years following treatment and have increased interest in others, a positive health outcome.
Diana McIntyre approaches her 80th birthday later this year with the same energy and zest for life of friends decades her junior. Aside from back surgery years ago, she's never been sick and, through a busy volunteer schedule, never seems to slow down.
McIntyre's good health feels normal—at least to her—although she recognizes not all seniors are so fortunate. But when it comes to terms like "normal," "healthy" or "successful" aging, she shakes her head.
Studying HIV-1, the most common and infectious HIV subtype, Johns Hopkins scientists have identified 25 human proteins "stolen" by the virus that may be critical to its ability to infect new cells. HIV-1 viruses capture many human proteins from the cells they infect but the researchers believe these 25 proteins may be particularly important because they are found in HIV-1 viruses coming from two very different types of infected cells. A report on the discovery, published online in the Journal of Proteome Research on Feb.
According to a recent University of Eastern Finland (UEF) study, elevated cell sugar concentrations increase the production of hyaluronan which, in turn, promotes cancer growth. Regulating the production of hyaluronan may be a way to prevent the spreading of cancer.
Hyaluronan is a long, linear carbohydrate polymer present in the human body. It forms a coating on the surface of many cells and plays a key role in fetal development and in the maintenance of normal tissue balance.
Scientists are reporting "laboratory resurrections" of several 2-3-billion-year-old proteins that are ancient ancestors of the enzymes that enable today's antibiotic-resistant bacteria to shrug off huge doses of penicillins, cephalosporins and other modern drugs. The achievement, reported in the Journal of the American Chemical Society, opens the door to a scientific "replay" of the evolution of antibiotic resistance with an eye to finding new ways to cope with the problem.
Scientists at the University of Southampton have taken a significant and important step in keeping people safe from the most common form of meningitis in the UK.
Meningitis B (also known as Meningococcal group B or MenB) is one of the deadliest strains of meningitis. Each year, an average of 1,870 people in the UK are affected by the disease with one in 10 people dying from it.
In an advance toward glass that remains clear under the harshest of conditions, scientists are reporting development of a new water-repellant coating that resists both fogging and frosting. Their research on the coating, which could have uses ranging from automobile windshields to camera lenses, appears in the journal ACS Nano.
