New method of testing for West Nile virus

While the United States has largely been spared the scourge of mosquito-borne diseases endemic to the developing world-including yellow fever, malaria and dengue fever-mosquito-related illnesses in the US are on the rise. One pathogen of increasing concern in the U.S. is an arbovirus known as West Nile.

Pleiotrophin protein may be long-sought growth factor for blood stem cells

Duke Medicine researchers studying the interaction of blood stem cells and the niche where they reside have identified a protein that may be a long-sought growth factor for blood stem cells.

UNM Cancer Center scientist to continue histone modification study

While every one of our cells contains all of our genetic information, each type of cell uses only specific parts of that information to make its proteins. Uncovering more about the mechanism that directs which particular pieces of genetic information the cell uses is the research focus of Mary Ann Osley, PhD, University of New Mexico Professor of Molecular Genetics and Microbiology and Co-Leader of the Cancer Biology and Biotechnology Program at the UNM Cancer Center.

New biomarker measures aggressiveness of primary prostate tumors

Research out of Roswell Park Cancer Institute (RPCI) supports the adoption of a new biomarker to measure the aggressiveness of primary prostate tumors.

Novel approach to assemble the 'connectome' via genetic barcoding

A team of neuroscientists has proposed a new and potentially revolutionary way of obtaining a neuronal connectivity map (the "connectome") of the whole brain of the mouse. The details are set forth in an essay published October 23 in the open-access journal PLOS Biology.

New Jersey's GDL decal requirement lowers crash rates among intermediate teen drivers

A new study from The Children's Hospital of Philadelphia (CHOP) provides initial evidence that New Jersey's Graduated Driver Licensing (GDL) decal requirement lowers crash rates among intermediate (i.e., probationary) teen drivers and supports the ability of police to enforce GDL provisions.

Study to examine possible link between mitochondrial DNA and ovarian cancer

Ovarian cancer is a deadly disease. With no overt symptoms and no screening tests to catch it early, ovarian cancer is often detected at stage 3 or later. By then, it can be very aggressive and may have spread beyond the ovaries into other organs. Many women eventually succumb to it; the five-year survival rate for a stage 3 ovarian cancer diagnosis is only 34 percent.

TSRI scientists to study structural rules that govern nuclear receptors

A consortium of scientists from both campuses of The Scripps Research Institute (TSRI) has been awarded $2.7 million from the National Institute of General Medical Sciences of the National Institutes of Health to study the structural rules that govern a large superfamily of proteins that help regulate critical functions such as reproduction, development and metabolism.

World-renowned cardiac researchers to speak at SDSU-hosted symposium

Prominent cardiac researchers will meet at San Diego State University in November to explore bold new approaches to treating the number one threat to U.S. adults - heart disease.

Vascular cell generation could be used to treat vascular disorders

A study in mice has shown that large numbers of vascular endothelial cells can be generated from human amniotic fluid-derived cells.

Researchers increase potency of a compound that reactivates antibiotics against MRSA

Researchers from North Carolina State University have increased the potency of a compound that reactivates antibiotics against methicillin-resistant Staphylococcus aureus (MRSA), an antibiotic-resistant form of Staphylococcus that is notoriously difficult to treat. Their improved compound removes the bacteria's antibiotic resistance and allows the antibiotic to once again become effective at normal dosage levels.

KIF3A protein ferries HIV to the plasma membrane

A study in The Journal of Cell Biology identifies a motor protein that ferries HIV to the plasma membrane, helping the virus escape from macrophages.

Most pediatric hospital physicians communicate through cell phone text messaging

More pediatric hospital physicians are communicating through cell phone text messaging, rather than the traditional pager method, according to research presented Oct. 21 at the American Academy of Pediatrics (AAP) National Conference and Exhibition in New Orleans.

Study looks at DNA sequences for receptors in T lymphocytes

Our immune system must be tremendously complex to respond to the unending assault of viruses, bacteria and cancerous cells. One of the mechanisms used by the immune system to cope with the huge variety of possible threats is to randomly combine DNA segments for the production of receptors on lymphocytes - a type of white blood cell.

Blood-circulating monocytes can replace brain resident microglia

The immune system is comprised of multiple cell types each capable of specialized functions to protect the body from invading pathogens and promote tissue repair after injury. One cell type, known as monocytes, circulates throughout the organism in the blood and enters tissues to actively phagocytose (eat!) foreign cells and assist in tissue healing.

Bodyguard macrophages protect stem cells from over-differentiation

Hiding deep inside the bone marrow are special cells. They wait patiently for the hour of need, at which point these blood forming stem cells can proliferate and differentiate into billions of mature blood immune cells to help the body cope with infection, for example, or extra red blood cells for low oxygen levels at high altitudes. Even in emergencies, however, the body keeps to a long-term plan: It maintains a reserve of undifferentiated stem cells for future needs and crises.
