Roundup: Fla., Texas, Minn., Ga., Conn., Mass. officials examine state health programs

Nullification - the legal theory that says a state can prevent enforcement of federal laws within its borders -- is the latest attempt to block Obama's health-care law at the state level. And brings with it new controversies and considerable confusion. For example, supporters and opponents of nullification reference the same language in the Constitution.

New research: Homophobic social environments may disrupt hormonal responses in LGB adults

Young adults who are lesbian, gay or bisexual are at far higher risk for severe mental health problems than their heterosexual peers. New research from Concordia University suggests that the stress of being rejected or victimized because of sexual orientation may disrupt hormonal responses in lesbians, gays and bisexuals.

International scientist team identifies gene mutation strongly linked to schizophrenia

In a major advance for schizophrenia research, an international team of scientists, led by Jonathan Sebat, PhD, assistant professor of psychiatry and cellular and molecular medicine at the University of California, San Diego School of Medicine, has identified a gene mutation strongly linked to the brain disorder - and a signaling pathway that may be treatable with existing compounds.

Researchers design nanoparticles that make blood clots visible to CT scanner

For almost two decades, cardiologists have searched for ways to see dangerous blood clots before they cause heart attacks. Now, researchers at Washington University School of Medicine in St. Louis report that they have designed nanoparticles that find clots and make them visible to a new kind of X-ray technology.

LSU biochemists develop 5-LOX 3-D model to design effective asthma medication

Chronic inflammation has been directly associated with heart disease and other physical ailments. But LSU graduate student Nathanial Gilbert and Professor of Biological Sciences Marcia Newcomer, together with Associate Professor Sue Bartlett, have developed the first 3-D model of Human 5-Lipoxygenase, or 5-LOX, the molecule responsible for creating inflammatory compounds that provoke asthma.

Study finds contradictory role of RIP1 protein in the liver during sepsis

Researchers from Rhode Island Hospital have identified a protein that plays a dual role in the liver during sepsis. The protein, known as RIP1, acts both as a "death switch" and as a pro-survival mechanism. The ability to identify the triggers for these functions may play a key role in treating sepsis in the future. The study is published online in advance of print in the journal Shock.

Malarial drugs may help treat specific form of frontotemporal dementia

Frontotemporal dementia is caused by a breakdown of nerve cells in the frontal and temporal region of the brain, which leads to, among other symptoms, a change in personality and behavior. The cause of some forms of frontotemporal dementia is a genetically determined reduction of a hormone-like growth factor, progranulin.

Agilent introduces first commercial RNA target enrichment system

Agilent Technologies, Inc., today introduced SureSelect RNA Capture Kits, the first commercial RNA target enrichment system enabling geneticists to focus on specific genomic loci or transcripts of research interest. The RNA capture kits make it possible to precisely measure expression levels of genes of interest and detect allelic-specific expression, splicing events and gene fusions.
