Johns Hopkins scientists find a source of nonallergic itch

Scratching below the surface of a troublesome sensation that's equal parts tingle-tickle-prickle, sensory scientists from Johns Hopkins have discovered in mice a molecular basis for nonallergic itch.

NHLBI grant for identifying genetic and epigenetic causes of human congenital heart disease

Researchers at Children's Hospital Boston and Brigham and Women's Hospital have received funding from the National Heart, Lung, and Blood Institute (NHLBI) to support their search for undiscovered gene defects that cause congenital heart disease. The $4.19 million, 6-year grant is part of the Pediatric Cardiac Genomics Consortium (PCGC), which seeks to identify genetic and epigenetic causes of human congenital heart disease, and relate genetic variants present in the congenital heart disease patient population to clinical outcomes.

Protein adenylyl cyclase senses and regulates pH blood levels

Researchers have identified the protein mechanism that senses bicarbonate fluctuations and adjusts blood pH levels.. A Canadian/U.S. research team led by University of Alberta biological sciences professor, Greg Goss and his graduate students Martin Tresguerres and Scott Parks achieved the first demonstration of the process in a whole animal. The researchers found that the protein adenylyl cyclase sensed and then regulated the pH blood levels in a dogfish shark following feeding.

Researchers develop new approach for treating and healing skin abscesses

Researchers at the Albert Einstein College of Medicine of Yeshiva University have developed a new approach for treating and healing skin abscesses caused by bacteria resistant to most antibiotics.

New drug to stop cancer cells from growing and to stimulate immune system to destroy cancer cells found

A study conducted at Scott & White Healthcare in Temple, Texas, found that a new drug stopped the growth of breast tumors in mice. This drug is unique in that it works both by stopping the cancer cells from growing and metastasizing to other organs, and by stimulating the immune system to destroy breast cancer cells and keeps them from coming back.

Hormone ghrelin influences the consumption of alcohol, study shows

A Faculty of 1000 evaluation examines how a stomach-produced hormone that influences the desire to eat and consume alcohol could be switched off to control drinking problems.

High prevalence of type 2 diabetes may be linked to excess niacin intake

Facing the increasing prevalence of type 2 diabetes worldwide in the past few decades, one may ask what is wrong with humans. Geneticists tell us that the human genome has not changed markedly in such a short time.

New project analyzes genetic sequence and variations of every gene expressed by 1,000 tumors

No two tumors are alike, but analyzing the genetics of cancers from different parts of the body may reveal surprising details useful for treatment and prevention.

Bacterial cellulose: An alternative for artificial blood vessels

The cellulose produced by bacteria could be used for artificial blood vessels in the future as it carries a lower risk of blood clots than the synthetic materials currently used for bypass operations, reveals a thesis from the Sahlgrenska Academy at the University of Gothenburg, Sweden.

Tel Aviv University's new Genome Analyzer fuels research dreams and tomorrow's cures

To identify the hemophilia mutation that affected Queen Victoria and her European relatives, scientific detectives used a cutting-edge "deep sequencing tool." Able to trace rare genetic disease mutations, the tool can turn a single laboratory into a fertile genetic research center.

Endocannabinoid modulation of sweet taste receptors may help control feeding behavior

Sweet taste responses were enhanced by endocannabinoids in every case. The effect was specific for sweet taste, as endocannibinoids had no effect on responses to sour, salty, bitter or umami taste stimuli.

Researchers to discover how to combat the negative aspects of fungi

Mold and mildew may be doomed. Researchers are closer to understanding how these and other fungi grow. "Fungi have a big impact on our dinner plate," said Dr. Brian Shaw, Texas AgriLife Research plant pathologist.

Researchers develop new technique for pH adjustments

How do individual cells or proteins react to changing pH levels? Researchers at the MESA+ Institute for Nanotechnology at the University of Twente have developed a technique for 'gently' adjusting pH: in other words, without damaging biomolecules. This should soon allow them to measure the activity of a single enzyme as a function of pH.

Genome-wide study of African and African-American ancestry released by scientists

People who identify as African-American may be as little as 1 percent West African or as much as 99 percent, just one finding of a large-scale, genome-wide study of African and African-American ancestry released today.

Researchers use hydrogels to induce significant vasculature growth in areas of damaged tissue

Regenerative medicine therapies often require the growth of functional, stable blood vessels at the site of an injury. Using synthetic polymers called hydrogels, researchers at the Georgia Institute of Technology have been able to induce significant vasculature growth in areas of damaged tissue.

Scientists identify role of epigenetic changes in SLE

Identical twins look the same and are nearly genetically identical, but environmental factors and the resulting cellular changes could cause disease in one sibling and not the other.

Proline repeats make teeth strong and resilient

A simple amino acid that is repeated in the center of proteins found in tooth enamel makes teeth stronger and more resilient, according to new research at the University of Illinois at Chicago.

CD20 deficiency in humans results in impaired T cell-independent antibody responses

Antibodies directed against the protein CD20, which is expressed by immune cells known as B cells, are used to treat B cell non-Hodgkin lymphoma and rheumatoid arthritis.

Common variations in genes associated with microcephaly may explain differences in brain size

A group of Norwegian and American researchers have shown that common variations in genes associated with microcephaly - a neuro-developmental disorder in which brain size is dramatically reduced - may explain differences in brain size in healthy individuals as well as in patients with neurological and psychiatric disorders.

Scientists offer potential new way to combat malaria

Stopping male mosquitoes from sealing their sperm inside females with a 'mating plug' could prevent mosquitoes from reproducing, and offer a potential new way to combat malaria, say scientists publishing new results in PLoS Biology on 22 December.
