Scientists suggest that lateral habenula can be a prime locus of human depression

A team of neuroscientists at Cold Spring Harbor Laboratory, Brookhaven National Laboratory and UC San Diego has collected evidence suggesting that a previously overlooked portion of the brain could be a prime locus of human depression.

Study finds LC damage and reduction in noradrenaline levels in brain are linked with MS

Researchers at the University of Illinois at Chicago have shown for the first time that damage to a particular area of the brain and a consequent reduction in noradrenaline are associated with multiple sclerosis.

New method to identify communication pathways connecting distant regions within proteins

A School of Science at Indiana University-Purdue University Indianapolis biophysicist has developed a new method to identify communication pathways connecting distant regions within proteins.

Gilenya offers more benefits for MS therapy than previously realized

In September, patients suffering from multiple sclerosis (MS) received the welcome news that the U.S. Food and Drug Administration (FDA) had approved a promising new drug for their condition called Gilenya. Now, a team from The Scripps Research Institute has discovered that this drug's success may involve an unexpected biological mechanism acting within the central nervous system (CNS). This difference may mean that Gilenya offers even more benefits than previously realized and would represent the first MS therapy with direct CNS activities.

Study finds duplicated region of DNA in major depressive disorder

A large genetic study of people with major depression has found that a duplicated region of DNA on chromosome 5 predisposes people to the disorder. The gene involved plays an important role in the development of nerve cells, adding to evidence that disruptions in neurotransmission networks form a biological basis for depression.

Variation at gene locus associated with greater reproductive success

Since 1871, when Charles Darwin wrote The Descent of Man, it has been widely accepted that "Variability is the necessary basis for the action of selection." Variability is associated with the ability to adapt, which is clearly beneficial at a species level. But there is increasing evidence that genetic variability may also give rise to advantages at the level of the individual.

Study finds common gene variant in African Americans increases risk of kidney disease

In African Americans with kidney disease related to hypertension (high blood pressure), a common gene variant is associated with a sharply increased risk of progressive kidney disease, according to a study presented at the American Society of Nephrology's 43rd Annual Meeting and Scientific Exposition. End Stage Renal Disease (ESRD) associated with hypertension occurs in the African American population at a rate 13.1 times greater than that of their white counterparts.

Harvard researcher to receive 2010 Naomi Berrie Award from Columbia University Medical Center

Columbia University Medical Center will present the 2010 Naomi Berrie Award to a Harvard researcher who has made important advances in understanding the molecular basis for links between obesity, diabetes and heart disease. A promising young investigator at Columbia will also be recognized for her novel investigations regarding the basis for disordered lipid metabolism in diabetes.

Researchers suggest that genetic screening may predict heart attack risk

Testing for 11 specific genetic variations in hundreds of people with no history of heart disease provided information that led to revision of their estimated heart attack risk, say Mayo Clinic researchers.

Study: Gastric function and autonomic nervous system are impaired in obese individuals

Research on obesity examining the role of hormones and the autonomic functions of the digestive system was presented at the 75th Annual Scientific Meeting of the American CoIlege of Gastroenterology.

Discovery may aid in developing new psoriasis therapies

Scientists at the University of Michigan Heath System and their collaborators have found four new DNA “hotspots” that may one day help guide new treatments for psoriasis, one of the most common autoimmune diseases in the country.

Obese have impaired autonomic function which may lead to overeating

Research on obesity examining the role of hormones and the autonomic functions of the digestive system was presented at the 75th Annual Scientific Meeting of the American CoIlege of Gastroenterology.

EpiMark Analysis Kit simplifies DNA methylation analysis for epigenetics researchers

New England Biolabs (NEB) has launched a suite of new and validated products designed to simplify DNA methylation analysis for epigenetics researchers. These enzyme-based solutions address some of the challenges of the current methods, including the lack of a reproducible method for the analysis and quantitation of 5-hydroxymethlcytosine (5-hmC) in the epigenome.

New SymPath kit measures DBH activity of Sympathetic Nervous System

Biotech Corporation in acquiring licenses to commercialize 12 Neuro-biomarkers has first focused on SymPath(R) and is now ready to give you the opportunity to shed some light about this Neuro-biomarker of the Sympathetic Nervous System (SNS). Here is a peak into the research behind the Neuro-blood testing that will be available to all patients through their health system.

Researchers reveal Prozac reactions to increase serotonin level

The response time to antidepressants, such as Prozac, is around three weeks. The adaptation mechanisms of the neurons to antidepressants has, until now, remained enigmatic. In particular, the researchers have revealed, for the first time, a sequence of reactions caused by Prozac at the neuron level, which contributes to an increase in the amounts of serotonin, a chemical "messenger" essential to the brain, and deficient in depressive individuals.

HFSA to discuss 'Designing the Medical Home for Heart Failure Patients' at Scientific Meeting

The 14th Annual Scientific Meeting of the Heart Failure Society of America (HFSA) will feature a discussion titled "Designing the Medical Home for Heart Failure Patients." Contributors Dr. Mary Norine Walsh and Dr. Larry A. Allen will describe treatment and care strategies in the medical home model and how they impact both patients and caregivers.

Study finds common risk factors linked with painkiller addiction

A new Geisinger study begins to unlock the puzzle of painkiller (opioid) addiction - why some people are more likely to become addicted than others. Geisinger investigators have found that patients with four common risk factors have a significantly higher risk of addiction. In addition, a history of severe drug dependence and drug abuse compounds the risk.

Genome-wide study identifies key genetic variant associated with nonalcoholic fatty liver disease

Researchers at Massachusetts General Hospital found that patients with nonalcoholic fatty liver disease (NAFLD) who carry an allele of the PNPLA3 gene have an increased risk of developing advanced disease, including nonalcoholic steatohepatitis (NASH), fibrosis, and cirrhosis. A second study supported by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) validates these findings and further concludes that in pediatric patients, the same allele is associated with earlier disease presentation.
