NIH-funded study raises hope for recovery of some adult patients with brain disorder

Scientists have reversed behavioral and brain abnormalities in adult mice that resemble some features of schizophrenia by restoring normal expression to a suspect gene that is over-expressed in humans with the illness.

Weekend reading: Volunteers in the battle with heart disease; Psychiatry without medication; Owning your genes

Psychiatrists who take time with their patients are not the norm. It's not because others don't care. Rather the system rewards efficiency, not empathy.

Breathing motor vehicle emissions triggers change in HDL cholesterol

Academic researchers have found that breathing motor vehicle emissions triggers a change in high-density lipoprotein cholesterol, altering its cardiovascular protective qualities so that it actually contributes to clogged arteries.

Researchers discover connection between CB1 receptors and PTSD

In a first-of-its-kind effort to illuminate the biochemical impact of trauma, researchers at NYU Langone Medical Center have discovered a connection between the quantity of cannabinoid receptors in the human brain, known as CB1 receptors, and post-traumatic stress disorder, the chronic, disabling condition that can plague trauma victims with flashbacks, nightmares and emotional instability.

PCB concentrations affect both urban and rural communities, study finds

Since polychlorinated biphenyls are produced through industrial processes or activities, it is assumed that people living in industrial cities will have higher concentrations of these toxic chemicals in their blood than people in rural communities.

Prenatal exposure to flame retardants is associated with lower intelligence and hyperactivity in early childhood

Chemicals called polybrominated diphenyl ethers (PBDEs) have been used for decades to reduce fires in everyday products such as baby strollers, carpeting and electronics. A new study to be presented on Monday, May 6, at the Pediatric Academic Societies (PAS) annual meeting shows that prenatal exposure to the flame retardants is associated with lower intelligence and hyperactivity in early childhood.

Study: Combination of chemotherapy and nerve-protecting agents can prevent anemia

Cancer chemotherapy can cause peripheral neuropathy-nerve damage often resulting in pain and muscle weakness in the arms and legs. Now, researchers at Albert Einstein College of Medicine of Yeshiva University have discovered that chemo also induces an insidious type of nerve damage inside bone marrow that can cause delays in recovery after bone marrow transplantation.

Metallurgists use microwave oven to produce nanocrystal semiconductors

University of Utah metallurgists used an old microwave oven to produce a nanocrystal semiconductor rapidly using cheap, abundant and less toxic metals than other semiconductors. They hope it will be used for more efficient photovoltaic solar cells and LED lights, biological sensors and systems to convert waste heat to electricity.
