Animals Farmed For Meat Are The No. 1 Source Of Food Poisoning Bug, Study Shows (September 26, 2008) -- A study, based on DNA-sequence comparison of thousands of bacterial samples collected from human patients and animal carriers, found that 97 percent of campylobacteriosis cases sampled in Lancashire, UK, were caused by bacteria typically found in chicken and livestock. ... > full story
Peptide Ghrelin May Be Involved In Both Alcohol Dependence And Overeating (September 26, 2008) -- Ghrelin is a peptide found mostly in the stomach but also in the brain. Ghrelin is known to have an effect on food intake by increasing feelings of hunger and the urge to eat. New findings show that the ghrelin system may also be involved in addictive behaviors and brain reward. ... > full story
Social Class Dictates Cancer Risk (September 26, 2008) -- Cervical and lung cancer are more common in poor people while rates of breast cancer and melanoma are higher in the wealthy. A detailed analysis of the incidence of these four different kinds of cancer, carried out on more than 300,000 English cancer patients and published in BMC Cancer, describes the effects of socioeconomic group, region and age. ... > full story
Scientists Unmask Key HIV Protein, Open Door For More Powerful AIDS Drugs (September 26, 2008) -- Scientists have provided the most detailed picture yet of a key HIV accessory protein that foils the body's normal immune response. Based on the findings, the team is searching for new drugs that may someday allow infected people to be cured and no longer need today's AIDS drugs for a lifetime. ... > full story
Weight Loss Surgery May Be Associated With Bone Loss (September 26, 2008) -- Weight loss surgery may be linked to deficiencies in calcium and vitamin D and bone loss, according to a new study. ... > full story
Post-traumatic Stress Experienced By Family Members Months After Loved One's Stay In Intensive Care Unit (September 26, 2008) -- Family members may experience post-traumatic stress as many as six months after a loved one's stay in a hospital's intensive care unit (ICU), according to a new study. The study found that symptoms of anxiety and depression in family members of ICU patients diminished over time, but high rates of post-traumatic stress and complicated grief remained. ... > full story
Pigs Bred With Cystic Fibrosis Provide Model To Mimic Human Disease (September 26, 2008) -- Cystic fibrosis continues to be a lethal disease for humans despite the identification of the problematic gene two decades ago. Many humans born with CF -- the most common genetic disease in Caucasians -- often die because of a lung disease developed later. Scientists have been unable to develop an animal model that develops the fatal lung disease. Now, one researcher is producing pigs born with cystic fibrosis that mimic the exact symptoms of a newborn with CF. ... > full story
Broken Arm? Women Recover Muscle Strength More Slowly Than Men, After Cast Is Removed (September 26, 2008) -- Women are four times more likely than men to experience a broken forearm and require a cast (immobilization). To examine if casting had an effect on gender, researchers immobilized a limb from among volunteers of both sexes. They found men were able to regain 99 percent of their strength within a week of removing the cast, but women's strength was still 30 percent lower than before the cast was applied. ... > full story
Low Sperm Count May Be Associated With Prenatal Testosterone Excess (September 26, 2008) -- Exposure to an excess of sexual steroids, like testosterone, during fetal development may be a potential risk factor for low sperm count and motility, according to a new study. ... > full story
Unraveling 'Math Dyslexia' (September 26, 2008) -- New research could change the way we view math difficulties and how we assist children who face those problems. Scientists are using brain imaging to understand how children develop math skills, and what kind of brain development is associated with those skills. ... > full story
New Approach To Gene Therapy May Shrink Brain Tumors, Prevent Their Spread (September 26, 2008) -- Researchers are investigating a new approach to gene therapy for brain tumors -- delivering a cancer-fighting gene to normal brain tissue around the tumor to keep it from spreading. They have found that inducing mouse brain cells to secrete human interferon-beta suppressed and eliminated growth of human glioblastoma cells implanted nearby. ... > full story
Differences Between People And Animals On Calorie Restriction (September 26, 2008) -- Calorie restriction, a diet that is low in calories and high in nutrition, may not be as effective at extending life in people as it is in rodents, according to scientists. ... > full story
