Uncommon genetic deletions associated with short stature

New research sifts through the entire genome of thousands of human subjects to look for genetic variation associated with height. The results of the study, published by Cell Press in the December issue of the American Journal of Human Genetics, suggest that uncommon genetic deletions are associated with short stature.

Knocking out one copy of IGF1 receptor fails to increase life span of male mice

Scientists studying longevity thought it might be good to lack a copy of a gene, called IGF1 receptor, that is important in insulin signaling. Previous studies showed invertebrates that lacked the copy lived longer, even if their bodies were less responsive to insulin, the hormone that lowers blood sugar.

Two-drug combination may alleviate radiation sickness in people

A combination of two drugs may alleviate radiation sickness in people who have been exposed to high levels of radiation, even when the therapy is given a day after the exposure occurred, according to a study led by scientists from Dana-Farber Cancer Institute and Children's Hospital Boston.

Stress chemicals shut down and brain processes emotional experiences during REM sleep

They say time heals all wounds, and new research from the University of California, Berkeley, indicates that time spent in dream sleep can help. UC Berkeley researchers have found that during the dream phase of sleep, also known as REM sleep, our stress chemistry shuts down and the brain processes emotional experiences and takes the painful edge off difficult memories.

Metformin prevents growth of breast cancer cells in human cultures

An inexpensive drug that treats Type-2 diabetes has been shown to prevent a number of natural and man-made chemicals from stimulating the growth of breast cancer cells, according to a newly published study by a Michigan State University researcher.

Cell-penetrating or antimicrobial peptides could treat atopic eczema

Scientists have found that a strain of yeast implicated in inflammatory skin conditions, including eczema, can be killed by certain peptides and could potentially provide a new treatment for these debilitating skin conditions.

NIH grant to support Cedars-Sinai's Department of Neurology research

The National Institutes of Health has awarded a four-year, $1.4 million grant to Cedars-Sinai's Department of Neurology to study an unexpected recent discovery: After ischemic stroke - the type caused by a clogged artery but with no bleeding into the brain - a normal protein that plays a positive role in blood clotting escapes intact arteries and damages healthy brain cells.

Cancer medicine component could prevent heart attacks

A substance in medicines for cancer and epilepsy could also prevent heart attacks, according to researchers at the Sahlgrenska Academy at the University of Gothenburg, Sweden, who have been using it to stimulate the body's own defence system against blood clots.

TLRs contribute to brain damage following hypoxia in newborns

Two out of every thousand babies are at risk of brain damage in connection with birth. Researchers at the Sahlgrenska Academy at the University of Gothenburg, Sweden, have identified mechanisms behind these injuries, which could lead to better treatment and a richer life for the infants affected.

UCF researchers use stem cells to create nerve-muscle junctions

University of Central Florida researchers, for the first time, have used stem cells to grow neuromuscular junctions between human muscle cells and human spinal cord cells, the key connectors used by the brain to communicate and control muscles in the body.

Mutations that affect lysosomes play a role in causing persistent stuttering

Researchers at Washington University School of Medicine in St. Louis have obtained new evidence that at least some persistent stuttering is caused by mutations in a gene governing not speech, but a metabolic pathway involved in recycling old cell parts.

Study reveals principal mechanism of action for paracetamol

Researchers at King's College London have discovered how one of the most common household painkillers works, which could pave the way for less harmful pain relief medications to be developed in the future.

New procedure could be adapted for use with X-ray techniques in studying human health

For more than a century, the use of X-rays has been a prime diagnostic tool when it comes to human health. As it turns out, X-rays also are a crucial component for studying and understanding molecules, and a new approach -- just published by researchers at the University of Georgia -- may dramatically improve what researchers can learn using the technique.

Dendritic cells play a novel protective role in pancreas

NYU Langone Medical Center researchers have discovered the novel protective role dendritic cells play in the pancreas. The new study, published in the November issue of journal Gastroenterology, shows dendritic cells can safeguard the pancreas against acute pancreatitis, a sudden dangerous swelling and inflammation of the pancreas gland.

Scientists identify P-Rex1 protein key to movement of melanoblasts

Researchers from UNC Lineberger Comprehensive Cancer Center are part of a team that has identified a protein, called P-Rex1, that is key to the movement of cells called melanoblasts. When these cells experience uncontrolled growth, melanoma develops.
