Advances in Neuroimmune Biology explores maternal-fetal interactions

Fertility problems, recurrent miscarriages, and pregnancy complications can occur when maternal immunological tolerance of the fetus is impaired. G-rard Chaouat and colleagues from Inserm et Assistance Publique et Universit- Paris Sud Orsay, Hopital Antoine B-cl-re, Clamart Cedex, France, trace the evolution of the science of reproductive immunology to show how the current understanding of maternal-fetal tolerance/dialogue has developed, and its implications for the treatment of infertility disorders

Scientists reveal first-ever glimpse of complete kappa opioid receptor structure

At the molecular level, drugs like salvinorin A (the active ingredient of the hallucinogenic plant Salvia divinorum) work by activating specific proteins, known as receptors, in the brain and body.

Link between autism risk gene and changes in brain structure and connectivity

Healthy individuals who carry a gene variation linked to an increased risk of autism have structural differences in their brains that may help explain how the gene affects brain function and increases vulnerability for autism.

Study finds higher death rate in calorie-restricted models of IBD

In a surprising result, Michigan State University researchers looking at the effects of diet on bowel disease found that mice on a calorie-restricted diet were more likely to die after being infected with an inflammation-causing bacterial pathogen in the colon.

Cannabinoid drugs can directly inhibit HIV in late-stage AIDS

Mount Sinai School of Medicine researchers have discovered that marijuana-like chemicals trigger receptors on human immune cells that can directly inhibit a type of human immunodeficiency virus (HIV) found in late-stage AIDS, according to new findings published online in the journal PLoS ONE.

Scans reveal Williams syndrome-associated personality/temperament traits

A personality profile marked by overly gregarious yet anxious behavior is rooted in abnormal development of a circuit hub buried deep in the front center of the brain, say scientists at the National Institutes of Health. They used three different types of brain imaging to pinpoint the suspect brain area in people with Williams syndrome, a rare genetic disorder characterized by these behaviors.

MD Anderson, Transgenomic partner to evaluate use of ICE COLD-PCR

Transgenomic, Inc. today announced that it has begun a collaboration with The University of Texas MD Anderson Cancer Center to evaluate the use of the Company's very high sensitivity ICE COLD-PCR mutation detection technology in analysis of DNA isolated from circulating tumor cells (CTCs) in blood samples from patients with advanced cancer.

Researchers identify mechanism involved in positioning nuclei in muscle fibres

In order to move, living beings need muscles, and, more specifically, skeletal muscles that are controlled by the nervous system. Skeletal muscles are composed of cylindrical muscle fibres with a multitude of peripheral nuclei. Until now, little was known about the mechanism used to position nuclei on the edge of muscle fibres. A team of French-American researchers has tried to better understand the reasons behind nuclei layout.

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.

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.
