Researchers at National Jewish Health have discovered a novel target for the treatment of food allergies. Erwin Gelfand, MD, and his colleagues report in the October 2012 issue of the Journal of Allergy and Clinical Immunology that levels of the enz

A Protein's Role in Helping Cells Repair DNA Damage 2012-12-07

By University at Buffalo

In a new study, University at Buffalo scientists describe the role that a protein called TFIIB plays in helping cells repair DNA damage, a critical function for preventing the growth of tumors.

Caffeine's Effect On the Brain's Adenosine Receptors Visualized for the First Time 2012-12-07

By Society of Nuclear Medicine

Molecular imaging with positron emission tomography (PET) has enabled scientists for the first time to visualize binding sites of caffeine in the living human brain to explore possible positive and negative effects of caffeine consumption. According

Novel Technique to Produce Stem Cells from Peripheral Blood 2012-12-07

By The Journal of Visualized Experiments

Stem cells are a valuable resource for medical and biological research, but are difficult to study due to ethical and societal barriers. However, genetically manipulated cells from adults may provide a path to study stem cells that avoid any ethical

Feedback Loop Maintains Basal Cell Population 2012-12-07

By Joseph M. Valdez

Notch -- the protein that can help determine cell fate -- maintains a stable population of basal cells in the prostate through a positive feedback loop system with another key protein TGF beta (transforming growth factor beta), said Baylor College o

Male Fertility Can Be Restored After Cancer Treatment, Researchers Find 2012-12-07

By Brian P. Hermann

An injection of banked sperm-producing stem cells can restore fertility to male primates who become sterile due to cancer drug side effects, according to researchers at the University of Pittsburgh School of Medicine and Magee-Womens Research Instit

Gene Required for Nerve Regeneration Identified 2012-12-07

By Michelle C. Stone

A gene that is associated with regeneration of injured nerve cells has been identified by scientists at Penn State University and Duke University. The team, led by Melissa Rolls, an assistant professor of biochemistry and molecular biology at Penn S

Living Donors Fare Well Following Liver Transplantation, Study Finds 2012-12-07

By Leona Kim-Schluger, Sander Florman

Researchers in Japan report that health-related quality of life (HRQOL) for donors following living donor liver transplantation (LDLT) was better than the general Japanese population (the norm). This study -- one of the largest to date -- found that

Toilet Training Methods Not Responsible for Differences in Volume of Urinary Accidents 2012-12-07

By Marc Colaco

Parents: stop worrying about which toilet training method to use -- where urinary accidents in children are concerned, it doesn't matter. This clearly-stated message, published November 1in Clinical Pediatrics by physician researchers from the Unive

Targeting Drugs With Hydrogels 2012-12-07

By Prapatsorn Techawanitchai

Researchers in Japan have developed a technique which allows them to control and target drug delivery to specific sites of the body at specific times, thus reducing side effects and improving treatment dramatically.

Scientists Create 'Endless Supply' of Myelin-Forming Cells 2012-12-07

By C. R. McClain

In a new study appearing this month in the Journal of Neuroscience, researchers have unlocked the complex cellular mechanics that instruct specific brain cells to continue to divide. This discovery overcomes a significant technical hurdle to potenti

Computational Medicine Enhances Way Doctors Detect, Treat Disease 2012-12-07

By RL Winslow

Computational medicine, a fast-growing method of using computer models and sophisticated software to figure out how disease develops -- and how to thwart it -- has begun to leap off the drawing board and land in the hands of doctors who treat patien

Adding Soy to Diet Does Not Affect Onset of Menopausal Hot Flashes 2012-12-07

By Ellen B. Gold
