GFAP protein levels can help identify HIE in newborns

Johns Hopkins researchers have discovered that increased blood levels of a protein specific to central nervous system cells that are vital to the brain's structure can help physicians identify newborns with brain injuries due to lack of oxygen.

Researchers control itch without dulling morphine's pain-killing effects

Itching is one of the most prevalent side effects of powerful, pain-killing drugs like morphine, oxycodone and other opioids. The opiate-associated itch is so common that even women who get epidurals for labor pain often complain of itching. For many years, scientists have scratched their own heads about why drugs that so effectively suppress pain also induce itch.

Stopping necroptosis in keratinocytes prevents skin inflammation

The outer layer of the skin, called the epidermis, forms a critical physical and immunological wall that serves as the body's first line of defense against potentially harmful microorganisms. Most of the epidermis consists of cells called keratinocytes that build a mechanical barrier but also perform immune functions.

Faster cerebral cortex growth in infancy may lead to higher intelligence

New research suggests the growth rate of the brain's cerebral cortex in babies born prematurely may predict how well they are able to think, speak, plan and pay attention later in childhood. The research is published in the October 12, 2011, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Dual drug sneaks across the blood-brain barrier to fight HIV

In an advance toward eliminating pockets of infection in the brain that help make HIV disease incurable, scientists report the development of new substances that first plug the biological vacuum cleaner that prevents anti-HIV drugs from reaching the brain and then revert to an active drug to treat HIV.

Limited decision-making ability of individual cells is bolstered in masses

Researchers from Johns Hopkins have quantified the number of possible decisions that an individual cell can make after receiving a cue from its environment, and surprisingly, it's only two.

New technique stimulates stem cells after liver transplant to prevent rejection

Johns Hopkins researchers have developed a way to stimulate a rat's stem cells after a liver transplant as a means of preventing rejection of the new organ without the need for lifelong immunosuppressant drugs.

Laser-based analysis method can detect optical pressure differences in blood cells

U.S. Naval Research Laboratory researchers Dr. Sean J. Hart, Dr. Colin G. Hebert and Mr. Alex Terray have developed a laser-based analysis method that can detect optical pressure differences between populations or classes of blood cells that does not rely on prior knowledge, antibodies, or fluorescent labels for discrimination.

Scientists reprogram skin cells of patients with mental disorders into brain cells

For many poorly understood mental disorders, such as schizophrenia or autism, scientists have wished they could uncover what goes wrong inside the brain before damage ensues.

New insights into how adenovirus triggers an immune response

A Loyola University Chicago Stritch School of Medicine study could lead to improved gene therapies for conditions such as heart disease and cancer as well as more effective vaccines for tuberculosis, malaria and other diseases.

Cigarette smoke interferes with Cystic Fibrosis Transmembrane Conductance Regulator protein

If you smoke cigarettes, you have more in common with someone who has cystic fibrosis than you think. A new research report appearing online in the FASEB Journal shows that smoking cigarettes affects the lungs in a way that is very similar to cystic fibrosis, a life threatening disease affecting the lungs and other organs.

Hospitalized patients with anemia may not always benefit from transfusion

University of Kentucky researchers, including lead author Samy Selim of the Division of Cardiovascular Medicine and the Saha Cardiovascular Research Center, have recently published a paper suggesting that transfusion may not always be the best treatment for hospitalized patients with anemia.

Study reveals new regulatory elements in human genome

An international research team led by Kerstin Lindblad-Toh at the Broad Institute, US and Uppsala University, Sweden has mapped and compared the genomes of 29 mammals. The findings, published in Nature, reveal millions of new regulatory elements in the human genome that in various ways govern how proteins are formed. The new knowledge is important for our understanding of how mutations in human genes give rise to diseases.

Specific MIF gene variant plays a crucial role against bacterial infections

Why are some people prone to severe infections, while others handle them with less difficulty? A new research report appearing online in the FASEB Journal (http://www.fasebj.org) attempts to answer this question by shedding light on the genetic differences that influence our ability to fight off bacterial infections.
