Researchers discover a startling feature of early brain development

Researchers at the Salk Institute have discovered a startling feature of early brain development that helps to explain how complex neuron wiring patterns are programmed using just a handful of critical genes. The findings, published February 3 in Cell, may help scientists develop new therapies for neurological disorders, such as amyotrophic lateral sclerosis (ALS), and provide insight into certain cancers.

RBC transfusion improves physical fatigue in postpartum anemic women

In a study to be presented today at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting -, in Dallas, Texas, researchers will report findings that show that in women with acute postpartum anemia, due to excessive blood loss during delivery, red blood cell transfusion led to a statistically significant decrease in physical fatigue.

Molecular secrets behind halofuginone's power

For roughly two thousand years, Chinese herbalists have treated Malaria using a root extract, commonly known as Chang Shan, from a type of hydrangea that grows in Tibet and Nepal. More recent studies suggest that halofuginone, a compound derived from this extract's bioactive ingredient, could be used to treat many autoimmune disorders as well. Now, researchers from the Harvard School of Dental Medicine have discovered the molecular secrets behind this herbal extract's power.

Curcumin may block growth of castrate-resistant prostate tumors

Curcumin, an active component of the Indian curry spice turmeric, may help slow down tumor growth in castration-resistant prostate cancer patients on androgen deprivation therapy (ADT), a study from researchers at Jefferson's Kimmel Cancer Center suggests.

First study to ever quantify effects of estrogen as a stimulant of pheromones

A new study has shown that boosting the estrogen levels of male garter snakes causes them to secrete the same pheromones that females use to attract suitors, and turned the males into just about the sexiest snake in the neighborhood - attracting dozens of other males eager to mate.

Research team studies effect of anabolic steroids on body fat

A research team at Luleå University of Technology and Umea University has, in a unique study involving ten Swedish elite lifters who are actively using anabolic steroids, studied the effect of Anabolic steroids on body fat. Swedish elite lifters who use anabolic steroids have more dangerous fat distribution in the body.

Study reveals how SAMHD1 works to protect dendritic cells from HIV virus

A novel discovery by researchers at NYU Langone Medical Center and colleagues reveals a mechanism by which the immune system tries to halt the spread of HIV. Harnessing this mechanism may open up new paths for therapeutic research aimed at slowing the virus' progression to AIDS. The study appears online ahead of print today in Nature Immunology.

Study investigates how cytokine IFN-λ release is regulated

In new research appearing in this month's issue of the journal Nature Immunology, Roy Curtiss, director of the Center for Infectious Diseases and Vaccinology at the Biodesign Institute at Arizona State University, along with international collaborators, investigates the coordination of a particular type of immune response, involving the release of of IFN-λ- a cell-signaling protein molecule known as a cytokine.

Gene therapy to promote remyelination in mouse model of MS

Our bodies are full of tiny superheroes-antibodies that fight foreign invaders, cells that regenerate, and structures that ensure our systems run smoothly. One such structure is myelin-a material that forms a protective, insulating cape around the axons of our nerve cells so that they can send signals quickly and efficiently. But myelin, and the specialized cells called oligodendrocytes that make it, become damaged in demyelinating diseases like multiple sclerosis (MS), leaving neurons without their myelin sheaths.

UofL to receive Grand Challenges tuberculosis biomarkers grant

The University of Louisville announced today that it will receive a tuberculosis (TB) biomarkers grant through the Bill & Melinda Gates Foundation's Grand Challenges in Global Health program, an initiative which seeks to overcome persistent bottlenecks in creating new tools that can radically improve health in the developing world. James E. Graham, Ph.D., associate professor of microbiology and immunology at the UofL School of Medicine, will pursue an innovative research project to identify and validate TB biomarkers, titled "Disposable Sampling Plate and Breath Test to Identify Patients with Active Tuberculosis."

New 3D computer model to understand cancer development

Observing that certain cancer cells may exhibit greater flexibility than normal cells, some scientists believe that this capability promotes rapid tumor growth. Now computer simulations developed by Boston University Biomedical Engineering Assistant Professor Muhammad Zaman and collaborators at the University of Texas at Austin appear to support this view.
