Meditation improves ability to cope with stress and increases telomerase activity

Calmly meditating produces exciting, beneficial effects on your body. It can protect your DNA against cancer-promoting genetic developments and free you from everyday stresses and distractions. That's why meditation is one of the most powerful, but often neglected, tools for maintaining optimal health.

Early disruptions in serotonin signaling may contribute to ASD

Early disruptions in serotonin signaling in the brain may contribute to autism spectrum disorder (ASD), and other "enduring effects on behavior," Vanderbilt University researchers report.

PEGPH20 enzyme re-expands insides of blood vessels to allow more drugs to reach tumours

Cancer Research UK scientists have shown that an enzyme can re-expand the insides of blood vessels allowing more drugs and large antibody molecules to reach pancreatic tumours, according to research published in GUT today.

Elevated Aβ peptide levels may lead to onset of AD

The effects of the bacterial endotoxin lipopolysaccharide (LPS) has been found to elevate amyloid beta (Aβ) peptide levels in the brain, leading to short-term deficits in learning.

Issues and treatments of chronic skin wounds

The skin is the body's largest organ and an indispensable part of the immune system. As the body's outermost line of defense against microbes, the skin provides important protection against potentially toxic environmental elements. One subset of immune cells, thymus-derived T-cells play an important role in the skin's response to injury, particularly with respect to wound healing.

FKBP52 may prevent hyperphosphorylation of pathogenic Tau protein

New research in humans published today reveals that the so-called FKBP52 protein may prevent the Tau protein from turning pathogenic. This may prove significant for the development of new Alzheimer's drugs and for detecting the disease before the onset of clinical symptoms.

New perspective on why the immune system makes us worse while trying to make us well

A new article in The Quarterly Review of Biology helps explain why the immune system often makes us worse while trying to make us well.

Closer to effective screening for TB

An Australian scientist will bring effective screening for tuberculosis a step closer with his latest study in Vietnam- where he now lives and works.

Two new studies strongly support link between insulin resistance and Alzheimer's

An emerging body of research suggests that Alzheimer's disease may be linked to insulin resistance, constituting a third type of diabetes. This model is based on several observations including an increased risk of developing Alzheimer's disease for diabetic patients, and reduced insulin levels in the brain tissue of Alzheimer's disease patients. Though intriguing, the existing evidence does not reveal if defective insulin signaling is causative of Alzheimer's or how insulin resistance impacts cognitive function.

Curcumin can help prevent clumping of proteins in Parkinson's

Curcumin, a compound found in the spice turmeric, is proving effective at preventing clumping of a protein involved in Parkinson's disease, says a Michigan State University researcher.

New drug makes chemotherapy more effective in treating acute myeloid leukemia

Doctors at Washington University School of Medicine in St. Louis have shown that a new drug makes chemotherapy more effective in treating acute myeloid leukemia, a cancer of the white blood cells. Instead of attacking these cells directly, the drug helps drive them out of the bone marrow and into the bloodstream, where they are more vulnerable to chemotherapy.

Study identifies function of GlialCAM gene in brain edema

A study of the pathophysiology of this rare disease has uncovered one mechanism that destabilizes the homeostatic balance of brain cells causing edema.

Chemists produce first high resolution structure of HCV viral RNA-inhibitor complex

Chemists at the University of California, San Diego have produced the first high resolution structure of a molecule that when attached to the genetic material of the hepatitis C virus prevents it from reproducing.

Scientists investigate molecular mechanism of memory encoding in neurons

University of Alberta led research may have discovered how memories are encoded in our brains. Scientists understand memory to exist as strengthened synaptic connections among neurons. However components of synaptic membranes are relatively short-lived and frequently re-cycled while memories can last a lifetime.

Study determines why blood oranges develop anthocyanin pigments

The anthocyanin pigments that provide the "blood" color of blood oranges are not produced in significant amounts unless the fruit is exposed to cold conditions during its development or post-harvest. No cold exposure means poor anthocyanin production and the loss of the entire crop. This means that blood oranges can be grown in many areas of the world, but they are most likely to be exposed to the correct temperature conditions in only a few regions, including their major area of production in Sicily.

FDA, Agilent partner to develop new tools for detection of salmonella subtypes

Agilent Technologies Inc. today announced that it has entered into a Cooperative Research and Development Agreement with the U.S. Food and Drug Administration to develop new tools to detect and analyze pathogens in food.

Mayo Clinic researchers train mouse immune systems to eradicate skin cancer from within

Mayo Clinic researchers have trained mouse immune systems to eradicate skin cancer from within, using a genetic combination of human DNA from melanoma cells and a cousin of the rabies virus. The strategy, called cancer immunotherapy, uses a genetically engineered version of the vesicular stomatitis virus to deliver a broad spectrum of genes derived from melanoma cancer cells directly into tumors.

New antibiotic shows promise against bovine mastitis

Food-borne diseases might soon have another warrior to contend with, thanks to a new molecule discovered by chemists at the University of Illinois. The new antibiotic, an analog of the widely used food preservative nisin, also has potential to be a boon to the dairy industry as a treatment for bovine mastitis.
