Researchers provide new model for studying drug targets and therapies for AIH

A gene mutation disrupts the activity of certain immune cells and causes the immune system to erroneously attack the liver, according to a new animal study from the Icahn School of Medicine at Mount Sinai.

Bacterial crystal protein could be safe, inexpensive treatment for parasitic worms in humans

A benign crystal protein, produced naturally by bacteria and used as an organic pesticide, could be a safe, inexpensive treatment for parasitic worms in humans and provide effective relief to over a billion people around the world.

Findings open new perspectives for research on proteins that control metastasis

In experiments on zebrafish, Freiburg researchers have demonstrated that the same proteins that lead to the formation of metastases in humans also cause the cells to migrate during embryonic development.

Research reveals how brains pick out important sounds from noisy world

New research reveals how our brains are able to pick out important sounds from the noisy world around us. The findings, published online today in the journal eLife, could lead to new diagnostic tests for hearing disorders.

Bruker introduces AVANCE-IVDr platform for NMR clinical research and screening

Bruker today announces a standardized nuclear magnetic resonance (NMR) spectroscopy platform for its clinical and diagnostics partners that enables cost-effective, high-performance NMR clinical screening and IVD-by-NMR discovery, development and validation of novel NMR assays.

Study results suggest reexamination of biological, medical importance of X chromosome

Painstaking new analysis of the genetic sequence of the X chromosome—long perceived as the "female" counterpart to the male-associated Y chromosome—reveals that large portions of the X have evolved to play a specialized role in sperm production.

International Consortium receives grant to examine genetic reasons of schizophrenia in deletion syndrome patients

Today, the Royal College of Surgeons in Ireland (RCSI) will host a two day International Brain and Behaviour Consortium meeting on Chromosome 22q11.2 Deletion Syndrome (22q11.2DS).

Platelet activation inhibits host cell entry of HIV, shows research

Scientists of the DPZ have shown that platelet activation inhibits the host cell entry of HIV. Infection biologists of the German Primate Center (DPZ) under the direction of Stefan Pöhlmann have found evidence that platelets (thrombocytes) might constitute an innate defense against infection with the human immunodeficiency virus (HIV).

Research team receives NCI grant to develop precision therapies that kill cancer cells

A research team headed by Fred Hutchinson Cancer Research Center scientists Christopher Kemp, Ph.D., and Carla Grandori, M.D., Ph.D., has received a $4 million grant from the National Cancer Institute to develop precision therapies that selectively kill cancer cells while sparing normal, healthy tissue.

Four research teams receive NIH grants to explore use of genome sequencing in medical care

The National Institutes of Health has awarded four grants for up to four years to multidisciplinary research teams to explore the use of genome sequencing in medical care. The awards total approximately $6.7 million in the first year and, if funding remains available, approximately $27 million in total.

NIH study seeks genetic links to answer the 'Why?' of unexplained disorders

Even in the absence of a ready solution, knowing why a child faces physical, emotional and intellectual challenges is helpful to physicians and families. Researchers at the HudsonAlpha Institute for Biotechnology are using high throughput genomic sequencing to meet major diagnostic needs for childhood genetic disorders through a multi-year grant potentially totaling more than $7.6 million from the National Institutes of Health.

Astrocytes can protect brain tissue and reduce disability due to stroke

One of regenerative medicine's greatest goals is to develop new treatments for stroke. So far, stem cell research for the disease has focused on developing therapeutic neurons - the primary movers of electrical impulses in the brain - to repair tissue damaged when oxygen to the brain is limited by a blood clot or break in a vessel. New UC Davis research, however, shows that other cells may be better suited for the task.

Potential breakthrough to help prevent diabetes

The resistance to insulin seen in type 2 diabetics is caused partly by the lack of a protein that has not previously been associated with diabetes. This breakthrough could potentially help to prevent diabetes.

Research findings on brain development may shed light on neurological disorders

Dennis O'Leary of the Salk Institute was the first scientist to show that the basic functional architecture of the cortex, the largest part of the human brain, was genetically determined during development.

Researchers develop microbial washing technique to decontaminate fetal tissues

The use of central nervous system fetal tissues derived from routine elective abortions to provide stem cells for transplantation procedures aimed at restoring damage done by neurodegenerative diseases is an established therapy.

Melatonin pre-treatment greatly increases cell survival, say researchers

When melatonin, a hormone secreted by the pineal gland, was used as a pre-treatment for mesenchymal stem cells prior to their transplantation into the brains of laboratory animals to repair damage from stroke, researchers in China found that the stem cells survived longer after transplantation. Previous studies had shown that 80 percent of transplanted MSCs died within 72 hours of transplantation.
