Clinically depressed individuals show reduced brain function

Clinically depressed individuals are less capable of finding pleasure in activities they previously enjoyed, a recent study has proven. Research featured in the August 26 issue of the NeuroReport shows reduced brain function in the reward center of the brain in depressed individuals, when compared to healthy subjects.

Study shows lower short-term mortality rates in patients hospitalized for AMI

From 1995 to 2006, hospital 30-day death rates decreased significantly for Medicare patients hospitalized for a heart attack, as did the variation in the rate between hospitals, according to a study in the August 19 issue of JAMA.

Neurofeedback 'brain training' helps surgeons improve skills

A team of researchers have found that trainee eye surgeons can significantly improve their surgical skills by regulating their own brainwave activity, using a process called neurofeedback.

Texas Heart Institute receives $4.1 million to determine the effect of pulseless blood flow on bodily functions

The National Institutes of Health (NIH) has awarded a $4.1 million grant to the Texas Heart Institute at St. Luke’s Episcopal Hospital (THI at SLEH) to determine the effect of pulseless blood flow on bodily functions. This knowledge will be used in the development of a total artificial heart (TAH) that produces continuous, pulseless blood flow.

Mediterranean-type diet and exercise lowers Alzheimer's risk

Both being more physically active and adhering to a Mediterranean-type diet appears to be associated with reduced Alzheimer's risk, according to a new report in the August 12, 2009 issue of the Journal of the American Medical Association (JAMA).

Disrupting the DNA-repair process

Scientists at Dana-Farber Cancer Institute have uncovered the mechanism behind a promising new approach to cancer treatment: damaging cancer cells' DNA with potent drugs while simultaneously preventing the cells from repairing themselves.

Novel genome-analysis strategy to speed search for gene-disease links

University of Washington (UW) researchers have successfully developed a novel genome-analysis strategy for more rapid, lower cost discovery of possible gene-disease links. By saving time and lowering expenses, the approach makes it feasible for scientists to search for disease-causing genes in people with the same inherited disorder but without any family ties to each other.

DNA evidence found at crime scenes can easily be falsified

Nucleix, Ltd., an emerging life science company specializing in forensic DNA analysis, announced that company researchers have proven DNA evidence found at crime scenes can easily be falsified using basic equipment, know-how and access to DNA or a DNA database.

New colon cancer target

New research led by scientists at the University of North Carolina at Chapel Hill School of Medicine have found a drug target that suggests a potent way to kill colon cancers that resist current drugs aimed at blocking a molecule found on the surface of cells.

Prion found to be a biomarker for pancreatic cancer

Mad cow disease is caused by the accumulation of an abnormal protein, the prion, in the brain of an affected patient. Outside of the brain, very little is known about prions.

New findings on how hepatitis C survives for so long in the body

Researchers at the University of Leeds have discovered a previously unknown mechanism that allows the hepatitis C virus (HCV) to remain in the body for decades.

Aspirin improves survival after colorectal cancer diagnosis

Men and women who were diagnosed with colorectal cancer and began regular use of aspirin had a lower risk of overall and colorectal cancer death compared to patients not using aspirin, according to a study in the August 12 issue of JAMA.

Smoking increases risk for brain shrinkage in multiple sclerosis

People who smoke and have multiple sclerosis (MS) may be at increased risk of brain shrinkage and increased brain lesions related to the disease, according to a study published in the August 18, 2009, print issue of NeurologyÂ®, the medical journal of the American Academy of Neurology. Smoking has already been linked to an increased risk of developing MS.

Protein Huwe1 may be an important factor in the development of brain cancer

Researchers from Columbia University Medical Center's Herbert Irving Comprehensive Cancer Center have identified a protein that activates brain stem cells to make new neurons - but that may be hijacked later in life to cause brain cancer in humans. The protein called Huwe1 normally functions to eliminate other unnecessary proteins and was found to act as a tumor suppressor in brain cancer.

Sugar "feeds" tumors

Researchers at Huntsman Cancer Institute at the University of Utah have uncovered new information on the notion that sugar "feeds" tumors. The findings may also have implications for other diseases such as diabetes. The research is published in the journal Proceedings of the National Academy of Sciences.

Nematode worm provides model of invasive cancer

A single cell in a 1-millimeter nematode worm is providing valuable new clues into cancer's deadliest behavior -- its ability to put down roots in new tissues after spreading throughout the body.

Running and addiction

Although exercise is good for your health, extreme exercise may be physically addicting. Rats given a drug that produces withdrawal in heroin addicts went into withdrawal after running excessively in exercise wheels, according to new research. Rats that ran the hardest had the most severe withdrawal symptoms.

Mother's immune system may block fetal treatments for blood diseases

Pediatric researchers have resolved an apparent contradiction in the field of prenatal cell transplantation - a medical approach that holds future promise in correcting sickle cell disease and other serious congenital blood disorders. In a new study in animals, the researchers showed that the mother's immune response interferes with the offspring's earlier ability to tolerate transplanted donor cells.
