Researchers highlight importance of motivating people to seek HIV testing

HIV infected patients whose treatment is delayed not only become sicker than those treated earlier, but also require tens of thousands of dollars more in care over the first several years of their treatment.

Researchers unveil new method to target and destroy cancerous cells

Using hyperthermia, Virginia Tech engineering researchers and a colleague from India unveiled a new method to target and destroy cancerous cells. The research was presented at the 63rd annual meeting of the American Physical Society Nov. 23 in Long Beach, Calif.

GFAP levels predict brain injury, death in critically ill children on ECMO

Johns Hopkins Children's Center scientists have discovered that high blood levels of a protein commonly found in the central nervous system can predict brain injury and death in critically ill children on a form of life support called extra-corporeal membrane oxygenation or ECMO.

Researchers identify trigger mechanism for quality control checkpoint in cell division process

Researchers from Huntsman Cancer Institute (HCI) at the University of Utah report that they have identified a previously undiscovered trigger mechanism for a quality control checkpoint at the very end of the cell division process in a paper to be published in the November 29 issue of The Journal of Cell Biology and online today.

Researchers investigate ways to counteract unhealthy effects of fat

A fat yet muscular mouse is helping researchers learn whether more muscle improves the cardiovascular health of obese individuals. We are looking for ways to counteract the unhealthy effects of fat, said Dr. David Stepp, vascular biologist at the Medical College of Georgia Vascular Biology Center and co-director of MCG's Diabetes & Obesity Discovery Institute.

Largest genomic study of human medulloblastomas

Medulloblastomas are the most common malignant brain tumors of childhood, with 40 to 50 percent overall mortality. One of the greatest challenges in treating them is that they vary substantially from patient to patient. In the largest genomic study of human medulloblastomas to date, researchers from Children's Hospital Boston, together with collaborators, have identified six subtypes with distinct molecular "fingerprints" that will improve doctors' ability to direct and individualize treatment.

Mother’s high-fat diet alters fetal genes that regulate circadian rhythm: Study

The link between sleeping and obesity is drawn tighter as a new research published online in the FASEB Journal study shows that what your mother ate when she was pregnant may make you obese or overweight by altering the function of genes (epigenetic changes) that regulate circadian rhythm.

Researcher develops new method that causes cancer cells to self-destruct

Tulane University researcher W T. Godbey has developed a treatment for cancer using a method that causes cancer cells to self-destruct while sparing surrounding healthy cells.

Breakthrough with mutant gene that causes familial ALS

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease that eventually destroys most motor neurons, causing muscle weakness and atrophy throughout the body. There is no cure and the current treatment has only a moderate effect on the march of the disease, which typically kills within three to five years. This week in PNAS, a team of Brandeis scientists reports an innovative approach to treating the most common form of familial ALS, commonly known as Lou Gehrig's disease.

New computer method measures mechanical stress in fat cells

From fad diets to exercise programs, Americans continue to fight the battle of the bulge. Now they'll have help from recent Tel Aviv University research that has developed a new method to look at how fat cells which produce the fat in our bodies respond to mechanical loads.

Compugen announces development of Protein Family Members Discovery Platform

Compugen Ltd. announced today the development of its Protein Family Members Discovery Platform, designed for the discovery of novel protein members belonging to various known and clinically important protein families.

Rate, direction of axon growth in spinal cord can be controlled, study shows

Both the rate and direction of axon growth in the spinal cord can be controlled, according to new research by USC College's Samantha Butler and her collaborators.

Different digestive tract bacteria helps infants digest milk more effectively than adults

Infants are more efficient at digesting and utilizing nutritional components of milk than adults due to a difference in the strains of bacteria that dominate their digestive tracts. Researchers from the University of California, Davis, and Utah State University report on genomic analysis of these strains in the November 2010 issue of the journal Applied and Environmental Microbiology identifying the genes that are most likely responsible for this difference.

Transparent develops new medium for Cell-able array kit to maintain metabolite activity

Transparent Inc. announced that it has developed a more advanced medium for Cell-able, a human hepatocyte array kit that has the potential to reduce drug development costs and time-to-market for pharmaceutical companies. Transparent first introduced Cell-able in the United States a year ago.

State roundup: Calif. stem cell research; Mass. prisons change HIV medicine procedure; Native Americans' high suicide rates

When millionaire Silicon Valley real estate developer Bob Klein launched his ballot drive to create a $3-billion state fund for stem-cell research in 2004, he pitched it as a way of taking politics out of science and focusing on cures.

FDA grants ACT clearance for Phase I/II clinical trial of hESC derived retinal cells in patients with SMD

Advanced Cell Technology, Inc. announced today that the US Food and Drug Administration (FDA) has cleared the Company's Investigational New Drug (IND) application to immediately initiate a Phase I/II multicenter clinical trial using retinal cells derived from human embryonic stem cells (hESCs) to treat patients with Stargardt's Macular Dystrophy (SMD), one of the most common forms of juvenile macular degeneration in the world. The decision removes the clinical hold that the FDA had placed on the trial.

Variation at gene locus associated with greater reproductive success

Since 1871, when Charles Darwin wrote The Descent of Man, it has been widely accepted that "Variability is the necessary basis for the action of selection." Variability is associated with the ability to adapt, which is clearly beneficial at a species level. But there is increasing evidence that genetic variability may also give rise to advantages at the level of the individual.

Researchers develop three-dimensional cancer cell from normal human tissue in culture dish

Researchers at the Stanford University School of Medicine have successfully transformed normal human tissue into three-dimensional cancers in a tissue culture dish for the first time. Watching how the cells behave as they divide and invade surrounding tissue will help physicians better understand how human cancers act in the body. The new technique also provides a way to quickly and cheaply test anti-cancer drugs without requiring laboratory animals.
