BPA substitute could spell trouble

A few years ago, manufacturers of water bottles, food containers, and baby products had a big problem. A key ingredient of the plastics they used to make their merchandise, an organic compound called bisphenol A, had been linked by scientists to diabetes, asthma and cancer and altered prostate and neurological development. The FDA and state legislatures were considering action to restrict BPA's use, and the public was pressuring retailers to remove BPA-containing items from their shelves.

Binge drinking can dramatically amplify damage to the liver

  • A new review examines studies addressing the effects of binge drinking on the liver.
  • Binge consumption of alcohol is implicated in the pathophysiology of ALD.
  • Binge drinking alters the levels of several cellular components and dramatically amplifies liver injury in the chronically alcohol-exposed liver.

Research finds substantial variation in readmission rate among children's hospitals

CHICAGO – In a national sample of 72 children's hospitals, 6.5 percent of hospitalized children experienced an unplanned readmission within 30 days, with significant variability in readmission rates across conditions and hospitals, according to a study appearing in the January 23/30 issue of JAMA.

Gay African-American youth face unique challenges coming out to families

NEW BRUNSWICK, N.J. – Coming out to one's family can be stressful, but gay black males face a unique set of personal, familial and social challenges.

UT MD Anderson scientists find protein that reins in runaway network

HOUSTON — Marked for death with molecular tags that act like a homing signal for a cell's protein-destroying machinery, a pivotal enzyme is rescued by another molecule that sweeps the telltale targets off in the nick of time.

The enzyme, called TRAF3, lives on to control a molecular network that's implicated in a variety of immune system-related diseases if left to its own devices.

The University of Texas MD Anderson scientists identified TRAF3's savior and demonstrated how it works in a paper published online Sunday in Nature.

NYUCN's Drs. Shedlin and Anastasi publish in the Journal of the Association of Nurses in AIDS Care

New York University College of Nursing (NYUCN) researchers Michele G. Shedlin, PhD, and Joyce K. Anastasi, PhD, DrNP, FAAN, LAc, published a paper, "Use of Complementary and Alternative Medicines and Supplements by Mexican-Origin Patients in a U.S.–Mexico Border HIV Clinic," in the on-line version of the Journal of the Association of Nurses in AIDS Care.

Novel gene-searching software improves accuracy in disease studies

A novel software tool, developed at The Children's Hospital of Philadelphia, streamlines the detection of disease-causing genetic changes through more sensitive detection methods and by automatically correcting for variations that reduce the accuracy of results in conventional software. The software, called ParseCNV, is freely available to the scientific-academic community, and significantly advances the identification of gene variants associated with genetic diseases.

Beta carotene may protect people with common genetic risk factor for type-2 diabetes

STANFORD, Calif. — Stanford University School of Medicine investigators have found that for people harboring a genetic predisposition that is prevalent among Americans, beta carotene, which the body converts to a close cousin of vitamin A, may lower the risk for the most common form of diabetes, while gamma tocopherol, the major form of vitamin E in the American diet, may increase risk for the disease.

Circadian rhythms can be modified for potential treatment of disorders

Irvine, Calif., Jan. 22, 2013 — UC Irvine-led studies have revealed the cellular mechanism by which circadian rhythms – also known as the body clock – modify energy metabolism and also have identified novel compounds that control this action. The findings point to potential treatments for disorders triggered by circadian rhythm dysfunction, ranging from insomnia and obesity to diabetes and cancer.

Study: Viral reactivation a likely link between stress and heart disease

COLUMBUS, Ohio – A new study could provide the link that scientists have been looking for to confirm that reactivation of a latent herpes virus is a cause of some heart problems.

Scientists discover 'needle in a haystack' for muscular dystrophy patients

Muscular dystrophy is caused by the largest human gene, a complex chemical leviathan that has confounded scientists for decades. Research conducted at the University of Missouri and described this month in the Proceedings of the National Academy of Sciences has identified significant sections of the gene that could provide hope to young patients and families.

Bacterial supplement could help young pigs fight disease

Jan. 22, 2013 - A common type of bacteria may help pigs stay healthy during weaning.

In a study of 36 weanling-age pigs, researchers found that a dose of lipid-producing Rhodococcus opacus bacteria increased circulating triglycerides. Triglycerides are a crucial source of energy for the immune system.

Genomic sequencing identifies mutant 'drivers' of common brain tumor

BOSTON—Large-scale genomic sequencing has revealed two DNA mutations that appear to drive about 15 percent of brain tumors known as meningiomas, a finding that could lead to the first effective drug treatments for the tumors, report scientists from Dana-Farber Cancer Institute and the Broad Institute.

New test predicted presence of harmful BRCA mutations

PHILADELPHIA — A new multiple gene expression profile test was able to predict the presence of harmful BRCA1 or BRCA2 mutations in otherwise healthy women carrying the mutations, according to data published in Cancer Prevention Research, a journal of the American Association for Cancer Research.

Wood on the seafloor -- an oasis for deep-sea life

Trees do not grow in the deep sea, nevertheless sunken pieces of wood can develop into oases for deep-sea life - at least temporarily until the wood is fully degraded. A team of Max Planck researchers from Germany now showed how sunken wood can develop into attractive habitats for a variety of microorganisms and invertebrates. By using underwater robot technology, they confirmed their hypothesis that animals from hot and cold seeps would be attracted to the wood due to the activity of bacteria, which produce hydrogen sulfide during wood degradation.
