• 23:22 Early-life exposure to BPA may affect testis function in adulthood

  Read the story at PhysOrg
  Exposure to environmental levels of the industrial chemical bisphenol A, or BPA, in the womb and early life may cause long-lasting harm to testicular function, according to a new study conducted in animals. The results are being presented Monday at The Endocrine Society's 92nd Annual Meeting in San Diego.

• 23:22 Electronic health records could give rise to more liability risk

  Read the story at PhysOrg
  Electronic health record systems likely will soon become a fixture in medical settings. Advocates claim they will reduce health care costs and improve medical outcomes, which could be critical since the new health care reform law increases access for millions of Americans. Although benefits of bringing information technology to health records can be substantial, EHR systems also give rise to increased liability risks for health care providers due to possible software or hardware problems or user errors.

• 23:22 Greater religiosity during adolescence may protect against developing problem alcohol use

  Read the story at PhysOrg
  Phenotypes are measurable and/or observable traits or behaviors. The heritability of an alcohol-related phenotype depends upon the social environment within which it is measured, such as urbanicity, marital status, or religiosity. A new study of the effects of religiosity on the genetic variance of problem alcohol use in males and females has found that religiosity can moderate genetic effects on problem alcohol use during adolescence but not during early adulthood.

• 23:22 Identification of a novel tumor suppressor

  Read the story at PhysOrg
  (PhysOrg.com) -- Scientists from the Friedrich Miescher Institute for Biomedical Research (FMI), have identified a novel tumor suppressor playing an important role in T-cell lymphoma. The protein kinase NDR1 has so far been implicated in the processes controlling cell death and centrosome duplication. In a recent study published in Science Signaling the FMI scientists show that T-cell lymphomas develop once the protein NDR1 is lost.

• 23:22 Many people with diabetes do not know or heed dangers of hot weather

  Read the story at PhysOrg
  A new survey shows that diabetic individuals who live in a hot climate have important gaps in their "heat awareness," or knowledge about proper diabetes self-care in hot weather, even though diabetes raises their risk of heat illness. The results of "Diabetes in the Desert: What Do Patients Know About the Heat?" will be presented Monday at The Endocrine Society's 92nd Annual Meeting in San Diego.

• 23:22 Puberty and sleep regulation can influence alcohol use during early adolescence

  Read the story at PhysOrg
  While alcohol in the form of a "night cap" may be able to help an individual fall asleep, its pharmacological properties later disrupt the rapid eye movement (REM) and deeper, more restorative stages of sleep. Sleep problems also predict the onset of alcohol abuse in healthy adults and relapse in abstinent alcoholics. A new study of associations among pubertal development, sleep preferences and problems, and alcohol use in early adolescence has found that puberty is related to sleep problems and later bedtimes, which were in turn associated with alcohol use.

• 23:22 Study examines, compares bacteria in the nose and throat

  Read the story at PhysOrg
  Scientists have completed the most comprehensive comparative analysis to date of bacterial communities inhabiting the human nose and throat, which could provide new insights into why some individuals become colonized with pathogens while others do not. They release their findings today in mBio the online open-access journal published by the American Society for Microbiology.

• 23:22 Studying cells in 3-D could reveal new cancer targets

  Read the story at PhysOrg
  Showing movies in 3-D has produced a box-office bonanza in recent months. Could viewing cell behavior in three dimensions lead to important advances in cancer research? A new study led by Johns Hopkins University engineers indicates it may happen. Looking at cells in 3-D, the team members concluded, yields more accurate information that could help develop drugs to prevent cancer's spread.

• 23:22 Women with polycystic ovary syndrome have higher BPA blood levels

  Read the story at PhysOrg
  Women with the polycystic ovary syndrome (PCOS), the most common hormone imbalance in women of reproductive age, may be more vulnerable to exposure to the chemical bisphenol A (BPA), found in many plastic household items, according to a new study. The results will be presented Sunday at The Endocrine Society's 92nd Annual Meeting in San Diego.

  Read the story at PhysOrg
  In a new Biological Psychiatry article, Dr. Regina Sullivan and colleagues have dissected the behavior of mother rats and their infant pups, modeling nurturing by stroking and abuse with electric shock. In this animal model of infant abuse, they took into consideration the unique infant neurobehavioral learning attachment system that ensures infant rats' attachment to their caregiver regardless of the quality of care received.

• 21:23 Brain signs of schizophrenia found in babies

  Read the story at PhysOrg
  Schizophrenia is a debilitating mental disorder affecting one in 100 people worldwide. Most cases aren't detected until a person starts experiencing symptoms like delusions and hallucinations as a teenager or adult. By that time, the disease has often progressed so far that it can be difficult to treat.

• 21:23 Fructose sugar makes maturing human fat cells fatter, less insulin-sensitive

  Read the story at PhysOrg
  Fructose, the sugar widely used as high-fructose corn syrup in soft drinks and processed foods, often gets some of the blame for the widespread rise in obesity. Now a laboratory study has found that when fructose is present as children's fat cells mature, it makes more of these cells mature into fat cells in belly fat and less able to respond to insulin in both belly fat and fat located below the skin.
