Scripps scientists to study several compounds with potential to improve QOL for ALS patients

A team led by scientists at The Scripps Research Institute has been awarded $2.1 million by the Department of Defense Congressionally Directed Medical Research Programs to study several compounds with the potential to greatly improve the quality of life for those with amyotrophic lateral sclerosis (ALS) or Lou Gehrig's disease.

Study sheds light on fundamental cellular process

Scientists at the Gladstone Institutes have mapped the precise frequency by which genes get turned on across the human genome, providing new insight into the most fundamental of cellular processes-and revealing new clues as to what happens when this process goes awry.

BDNF deletion plays a critical role in psychiatric disease and obesity

McGill researchers have identified a small region in the genome that conclusively plays a role in the development of psychiatric disease and obesity. The key lies in the genomic deletion of brain-derived neurotrophic factor, or BDNF, a nervous system growth factor that plays a critical role in brain development.

Scientists discover how protein deficiency may be linked to frontotemporal dementia

Using animal models, scientists at the Gladstone Institutes have discovered how a protein deficiency may be linked to frontotemporal dementia (FTD)-a form of early-onset dementia that is similar to Alzheimer's disease. These results lay the foundation for therapies that one day may benefit those who suffer from this and related diseases that wreak havoc on the brain.

New blood test can read genetic changes in prostate cancer

Scientists have designed a blood test that reads genetic changes like a barcode - and can pick out aggressive prostate cancers by their particular pattern of gene activity.

Prenatal fish consumption may reduce risk of ADHD-related behaviors

A study of children in the New Bedford, Mass., area suggests that low-level prenatal mercury exposure may be associated with a greater risk of attention-deficit/hyperactivity disorder (ADHD)-related behaviors and that fish consumption during pregnancy may be associated with a lower risk of these behaviors, according to a report published Online First by Archives of Pediatrics & Adolescent Medicine, a JAMA Network publication.

Endotrophin may serve as novel therapeutic target for breast cancer

Fat cells (adipocytes) surround breast tumors and contribute to tumor growth by expressing factors that aid oncogenesis. Col6 is a protein that is highly expressed in adipocytes and its expression is further increased in both obesity and in breast cancer cells.

Morphine inhibits BDNF protein, whereas cocaine enhances BDNF

Chronic morphine exposure has the opposite effect on the brain compared to cocaine in mice, providing new insight into the basis of opiate addiction, according to Mount Sinai School of Medicine researchers. They found that a protein called brain-derived neurotrophic factor (BDNF), which is increased in cocaine addiction, is inhibited in opioid addiction. The research is published in the October 5 issue of Science.

Liquorice-based nanotech material for sterilizing medical devices

A nanotech material containing an extract from liquorice can be used to sterilize and protect medical devices and implants which include biological components, and protects these functional bio-components during the sterilization process.

Power of alpha wave increases just before the distracter

Alpha waves were long ignored, but gained interest of brain researchers recently. Electrical activity of groups of brain cells results in brain waves with different amplitudes. The so called alpha wave, a slow brain wave with a cycle of 100 milliseconds seems to play a key role in suppressing irrelevant brain activity. The current hypothesis is that this alpha wave is associated with pulses of inhibition (every 100 ms) in the brain.

Sir John B. Gurdon and Shinya Yamanaka have won the 2012 Nobel Prize in Physiology or Medicine

The 2012 Nobel Prize in Physiology or Medicine has been awarded jointly to Sir John B. Gurdon and Shinya Yamanaka for the discovery that mature cells can be reprogrammed to become pluripotent.

Scientists discover process by which vitamin B12 is made in cells

In a development that may lead to new drugs to treat cancer, scientists at the University of Kent have discovered the process by which a key vitamin (B12) is made in cells.

Researchers discover new group of nerve cells that regulate processes of learning and memory

Swedish researchers at Uppsala University have, together with Brazilian collaborators, discovered a new group of nerve cells that regulate processes of learning and memory. These cells act as gatekeepers and carry a receptor for nicotine, which can explain our ability to remember and sort information.

CogniFit releases new cognitive training application

CogniFit, a leading developer of online brain training and cognitive programs announces the release of a new cognitive training application "Tennis Focus" to its online platform. The tasks of the Tennis Focus application are developed in 3D, train a large variety of cognitive skills such as focus, visual perception, visual scanning and eye-hand coordination.

Anesthetics and protein interactions: an interview with José A. Fernández

For a long time there was a controversy about how anesthetics work. The large number of molecules that have anesthetic properties (from benzodiazepines to nitrous oxide) and their very different structures...

Study provides direct evidence for persistent activity in medial entorhinal cortex layer neurons

UCLA researchers have for the first time measured the activity of a brain region known to be involved in learning, memory and Alzheimer's disease during sleep. They discovered that this part of the brain behaves as if it's remembering something, even under anesthesia, a finding that counters conventional theories about memory consolidation during sleep.

Researchers discover smallest and fastest-known RNA switches

A University of Michigan biophysical chemist and his colleagues have discovered the smallest and fastest-known molecular switches made of RNA, the chemical cousin of DNA. The researchers say these rare, fleeting structures are prime targets for the development of new antiviral and antibiotic drugs.

NFKB1 gene variant may reduce risk of lung cancer

A variant in a gene involved with inflammation and the immune response is linked with a decreased risk of lung cancer. That is the finding of an analysis published early online in CANCER, a peer-reviewed journal of the American Cancer Society. The results add to the growing body of literature implicating these processes in the development of lung cancer.

Researchers discover 8 new loci associated with susceptibility to atopic dermatitis

Researchers at the RIKEN Center for Genomic Medicine (CGM) and their colleagues have identified 8 new loci associated with susceptibility to atopic dermatitis in the Japanese population.

Researchers decipher how AP-1 gene regulator controls survival of liver tumor-initiating cells

Researchers headed by Erwin Wagner, the Director of the BBVA Foundation-CNIO Cancer Cell Biology Programme at the Spanish National Cancer Research Centre (CNIO), have deciphered how a stress-inducible gene regulator, AP-1, controls the survival of liver tumor-initiating cells. These results, published in the online edition of Nature Cell Biology, could provide new preventive strategies and identify potentially targetable molecules to prevent liver cancer.
