Obesity promotes prostate cancer by altering gene regulation Posted: 24 Sep 2012 05:25 PM PDT Prostate cancer is one of the most common cancers in men and early treatment is usually very successful. However, like other cancers, obesity increases the risk of aggressive prostate disease. New research finds that the fat surrounding the prostate of overweight or obese men with prostate cancer provides a favorable environment to promote cancer growth.

Feeling guilty versus feeling angry: Who can tell the difference? Posted: 24 Sep 2012 02:52 PM PDT The ability to identify and distinguish between negative emotions helps us address the problem that led to those emotions in the first place. But while some people can tell the difference between feeling angry and frustrated, others may not be able to separate the two. Clinically depressed people often experience negative emotions that interfere with everyday life. A new study examines whether clinically depressed people are able to discriminate between different types of negative emotions.

Cuba’s prenatal program improves low birth weights Posted: 24 Sep 2012 02:49 PM PDT Comprehensive prenatal care can decrease the rate of low birth weights, according to a new study.

Images of the precise location and extent of metastases could be used to guide surgery or ablation, or the same technology used to find the cancer could be used to deliver cancer-killing drugs.

Drug originally developed for cancer proves effective for children with progeria Posted: 24 Sep 2012 12:25 PM PDT Results of the first-ever clinical drug trial for children with progeria, a rare, fatal "rapid-aging" disease, demonstrate the efficacy of a farnesyltransferase inhibitor (FTI), a drug originally developed to treat cancer. The clinical trial results, completed only six years after scientists identified the cause of progeria, included significant improvements in weight gain, bone structure and, most importantly, the cardiovascular system.

Scientists reverse Alzheimer's-like memory loss in animal models by blocking EGFR signaling Posted: 24 Sep 2012 12:25 PM PDT Neuroscientists have published new research suggesting that EGFR inhibitors, a class of currently used anti-cancer drugs, as well as several previously untested synthetic compounds, show effectiveness in reversing memory loss in two animal models of Alzheimer's disease.

Like prostate cancer, bladder cancer patients may benefit from anti-androgen therapy Posted: 24 Sep 2012 12:25 PM PDT Bladder cancer patients whose tumors express high levels of the protein CD24 have worse prognoses than patients with lower CD24. A new study shows that CD24 expression may depend on androgens – and that anti-androgen therapies like those currently used to treat prostate cancer may benefit bladder cancer patients.

Primate study adds to evidence of BPA harming human reproduction Posted: 24 Sep 2012 12:25 PM PDT A researcher has found new evidence that the plastic additive BPA can disrupt women's reproductive systems, causing chromosome damage, miscarriages and birth defects. Scientists report seeing reproductive abnormalities in rhesus monkeys with BPA levels similar to those of humans.

Viruses help scientists battle pathogenic bacteria and improve water supply Posted: 24 Sep 2012 11:51 AM PDT Infectious bacteria received a taste of their own medicine from researchers who used viruses to infect and kill colonies of Pseudomonas aeruginosa, common disease-causing bacteria.

Eye proteins have germ-killing power, could lead to new antimicrobial drugs, study finds Posted: 24 Sep 2012 11:51 AM PDT When it comes to germ-busting power, the eyes have it, according to a new discovery that could lead to new, inexpensive antimicrobial drugs. Researchers found that small fragments of keratin protein in the eye play a key role in warding off pathogens.

Little evidence supports medical treatment options for adolescents with autism, researchers say Posted: 24 Sep 2012 11:40 AM PDT Researchers are reporting that there is insufficient evidence to support the use of medical interventions in adolescents and young adults with autism. Despite studies that show that many adolescents and young adults with autism spectrum disorders are being prescribed medications, there is almost no evidence to show whether these medications are helpful in this population, the researchers said.

Tissues tell the tale: Non-invasive optical technique detects cancer by looking under the skin Posted: 24 Sep 2012 11:29 AM PDT An international team of researchers has developed an advanced optics system to noninvasively map out the network of tiny blood vessels beneath the outer layer of patients' skin, potentially revealing telltale signs of disease.

Human brains outpace chimp brains in womb Posted: 24 Sep 2012 11:29 AM PDT Humans' superior brain size in comparison to their chimpanzee cousins traces all the way back to the womb. That's according to a study that is the first to track and compare brain growth in chimpanzee and human fetuses.

Eunuchs outlive other men Posted: 24 Sep 2012 11:29 AM PDT Castrated men living in Korea centuries ago outlived other men by a significant margin. The findings suggest that male sex hormones are responsible for shortening the lives of men, the researchers say.

You have to eat, except when you're not hungry Posted: 24 Sep 2012 11:26 AM PDT A study of siblings indicates a behavioral inclination toward obesity in children.

Newly discovered molecule could deliver drugs to treat diseases Posted: 24 Sep 2012 11:26 AM PDT Researchers have discovered a molecule that may be capable of delivering drugs inside the body to treat diseases.

Pregnancy complications up to twice higher in women born preterm Posted: 24 Sep 2012 11:24 AM PDT Women who were born premature are more likely to have pregnancy complications than women who weren't, according to new research. This study clearly shows the impact of preterm birth (i.e. before 37 weeks of gestation) itself on pregnancy risks. Low-weight at birth is an additional but independent risk factor.

Cancer researchers show why genetic risks promote breast cancer Posted: 24 Sep 2012 11:24 AM PDT Cancer researchers studying 44 known genetic variants associated with breast cancer have found the way to identify why they increase cancer risk, opening the door to future therapeutic applications based on personalized medicine.

Food for thought: Do family meals really make a difference for child academics or behavior? Posted: 24 Sep 2012 11:21 AM PDT Despite popular wisdom and findings from much previous research that suggests the beneficial impact of family mealtime, a rigorous analysis of 21,400 children, ages five to 15, brings a new argument to the table: When researchers controlled for a host of confounding factors, they didn't find any relationship between family meals and child academic outcomes or behavior.

Bees decrease food intake, live longer, when given compound found in red wine Posted: 24 Sep 2012 11:21 AM PDT Researchers have found that when given resveratrol, a compound found in red wine, bees consume less food.
