Researchers look at malaria resistance to chloroquine

Funded by a $1.5 million grant from the National Institutes of Health (NIH), scientists at Binghamton University, State University of New York, hope to understand how the malaria parasite Plasmodium falciparum evolved resistance to the once-effective medication chloroquine.

University of Utah receives $19.2 Million for HIV research

University of Utah biochemist Wesley I. Sundquist, Ph.D., has been awarded a five-year, $19.2 million National Institutes of Health (NIH) grant to establish an HIV research center to study the structural biology of the AIDS-causing virus.

New technique detects specific chromosomal damage - helps identify precancerous changes

A new technique could pave the way toward screening people at risk for lung cancer for the genetic changes that may foreshadow malignancies, researchers from the University of Colorado say.

First common height gene identified by researchers behind 'obesity gene' finding

Whilst we all know that tall parents are more likely to have tall children, scientists have been unable to identify any common genes that make people taller than others. Now, however, scientists have identified the first gene, known as HMGA2, a common variant of which directly influences height.

Genetic variant linked to human height discovered

It became clear nearly a century ago that many genes likely influence how tall a person grows, though little progress, if any, has followed in defining the myriad genes. Now an international research team brings light to this age-old question by pinpointing a genetic variant associated with human height - the first consistent genetic link to be reported.

Cell that triggers symptoms in allergy attacks can also limit damage

A blood cell known as a troublemaker for triggering the itch and inflammation in allergy attacks, the mast cell, can also calm down the flare-ups, researchers from Stanford University School of Medicine have found.

Novel methods for the regeneration of musculoskeletal tissues

A research group led by Dr. Cato T. Laurencin, with faculty representing five departments at the University of Virginia, will work on a first-of-its kind, $2 million grant project as they explore novel methods for the regeneration of musculoskeletal tissues.

Small animal imaging facility is big boon to research

When powerful magnets line up the body's protons before radiofrequency waves can grab their attention away, it's called spin physics.

Pancreatic cancer fights off immune attack

Scientists of the German Cancer Research Center (Deutsches Krebsforschungszentrum) and the Heidelberg University Hospitals have discovered that pancreatic cancer attracts regulatory T cells, which suppress the activity of immune cells.

New insights into knee injuries and osteoarthritis in the knee

The sort of swelling that occurs when a joint is damaged by injury or degeneration is normally essential to the healing process, but when it comes to the knee, that inflammation can actually interfere with healing.

Neurotransmitter current not flowing through ion channels

In studying how neurotransmitters travel between cells -- by analysis of events in the dimensions of nanometers -- Cornell researchers have discovered that an electrical current thought to be present during that process does not, in fact, exist.

Protein on the surface of platelets plays a key role in cancer-induced platelet aggregation

Scientists have provided new details about how cancer cells spread by surrounding themselves with platelets – the blood cells needed for blood clotting.

Researchers chart the level of gene expression in melanoma cell lines

Other than visually inspecting the disease, doctors have no genetic blueprint to classify melanomas, a lethal form of skin cancer.

Improving diagnosis of pancreatic cancer

In the August issue of Molecular & Cellular Proteomics, scientists provide the first large-scale identification of proteins that are overexpressed in chronic pancreatitis, an inflammatory condition of the pancreas that shares many features with pancreatic cancer.

New anti-cancer drug made from corn lillies kills brain tumor stem cells

A drug that shuts down a critical cell-signaling pathway in the most common and aggressive type of adult brain cancer successfully kills cancer stem cells thought to fuel tumor growth and help cancers evade drug and radiation therapy, a Johns Hopkins study shows.

Discovery may lead to new class of diabetes drugs

A multidisciplinary team led by researchers at the University of California, San Diego has determined the structure of a protein found in cells that shows potential as a target for the development of new drugs to treat diabetes.
