Coffee reduces risk of alcohol-induced pancreatitis

Pancreatitis is a condition in which the pancreas becomes inflamed, causing severe abdominal pain. It is often triggered by alcohol consumption which causes digestive enzymes to digest part of the pancreas.

Cells have a natural defense against HIV

Scientists here have discovered a previously unknown mechanism that cells use to fight off the human immunodeficiency virus (HIV), the cause of AIDS.

Researchers synthesize nisin in a test tube

Scientists have made nisin, a natural antibiotic used for more than 40 years to preserve food, in a test tube for the first time using nature's toolbox.

New AF267B drug reverses key cognitive deficits, pathology in Alzheimer's

A new drug that enhances the activity of a key brain cell receptor involved in Alzheimer's disease (AD) reverses learning and memory deficits in mice engineered to have pathological hallmarks of the disease.

Stroke researchers have traced the major cause of the death of brain cells

In the neurological train wreck that is stroke, researchers have traced the major cause of the death of brain cells due to artery blockage or bleeding in the brain.

A more accurate method for measuring blood levels of endothelial progenitor cells

A more accurate method for measuring blood levels of specialized cells that circulate in the bloodstream and repair damage to the arterial lining has been discovered by Duke University Medical Center cardiologists.

A map of recent positive selection in the human genome

By scanning the entire human genome in search of genetic variations that may signal recent evolution, University of Chicago researchers found more than 700 genetic variants that may be targets of recent natural positive selection during the past 10,000 years of human evolution.

Completely novel approach to fighting HIV infections

For more than a year, researchers watched patiently as a few computer-simulated HIV protease molecules squirmed into more than 15,000 slightly different shapes. In real time, this contortion takes only a fraction of a second.

New test for detecting small amounts of proteins in the blood

Researchers at the University of Pennsylvania School of Medicine have developed a paradigm-shifting method for detecting small amounts of proteins in the blood.

Trial explores safety and efficacy of injecting human stem cells directly into the brain to treat fatal pediatric neurodegenerative disorder

Researchers in Doernbecher Children's Hospital at Oregon Health & Science University will begin a Phase I clinical trial using stem cells in infants and children with a rare neurodegenerative disorder that affects infants and children.

Genetic switch that turns off an oxygen-poor cell's combustion engine - finding has potential to limit toxic molecules

Johns Hopkins researchers have discovered a previously unrecognized role played by the gene HIF-1 as it helps cell survive when a lack of oxygen decreases production of an energy-rich molecule called ATP and increases production of toxic molecules.

How mammalian brains recognize other individuals

Imagine seeing a former high school classmate you always wanted to know better. Then imagine seeing that kid who used to push you in the hallways. Do you react differently? What happens in your brain during these encounters?

Link between coffee consumption and risk of myocardial infarction greater with certain gene variation

Individuals who have a genetic variation associated with slower caffeine metabolism appear to have an increased risk of non-fatal heart attack associated with higher amounts of coffee intake

Test for LDH enzyme may help determine risk factors in sickle cell disease

Researchers have found that a simple test for an enzyme called LDH may have significant importance for determining major risk factors in adults with sickle cell disease.

Metabolic switch required for cellular adaptation to hypoxia

Two new studies in the March Cell Metabolism reveal a survival mechanism by which cells adapt to oxygen starvation by ratcheting down their demand.

Coffee good or bad for you? It depends on your genes!

Scientists know that coffee, a major source of caffeine, is metabolized by the enzyme, cytochrome P450 1A2, and some individuals who have that particular gene are "rapid" caffeine metabolizers, whereas those with a different variation of the gene are "slow" caffeine metabolizers.

Discovery of compound that reduces hallmark lesions of Alzheimer's disease in mice

Researchers at UC Irvine have found that a new compound not only relieves the cognitive symptoms of Alzheimer's disease, but also reduces the two types of brain lesions that are hallmarks of this devastating disease, thereby blocking its progression.

Genes play a key role in stress response

Both nature and nurture - genetic makeup and the environment experienced through life - combine to influence health and well-being, Duke University Medical Center researchers and their colleagues have determined in four new studies.
