Treating safety research like other clinical studies slows progress

Progress in patient safety research could slow to a crawl unless regulators work out a host of ethical issues, Johns Hopkins researchers assert in an upcoming opinion piece.

Just what is a binge drinker and how to get through to them

Just as governments in Australia and Britain are on the brink of introducing new measures to combat alcohol abuse and binge drinking, new research says that campaigns warning about the harmful effect of excessive alcohol consumption don't work.

Vitamin D protects cells from stress that can lead to cancer

By inducing a specific gene to increase expression of a key enzyme, vitamin D protects healthy prostate cells from the damage and injuries that can lead to cancer, University of Rochester Medical Center researchers report.

Supplemental breast ultrasound boosts cancer detection, radiologist reports in national study

Among women at high-risk of developing breast cancer, breast ultrasound combined with mammography may detect more cancers than mammography alone, according to results of a multicenter trial that included UT Southwestern Medical Center researchers.

Traffic pollution can be deadly as it increases the risk of deep vein thrombosis

Scientists in the U.S. have confirmed a long held suspicion that traffic pollution can be deadly for some people.

Researchers find link between altered dopamine activity and social anxiety disorder

Using single-photon emission computed tomography (SPECT), researchers in The Netherlands were able to detect biochemical differences in the brains of individuals with generalized social anxiety disorder (also known as social phobia), providing evidence of a long-suspected biological cause for the dysfunction.

Scientists identify heat sensing regulator - better understanding pain sensitivity

Neuroscientists at Johns Hopkins are a step closer to understanding pain sensitivity - specifically why it's variable instead of constant - having identified a gene that regulates a heat-activated molecular sensor.

How embryonic stem cells develop into tissue-specific cells demonstrated by researchers

While it has long been known that embryonic stem cells have the ability to develop into any kind of tissue-specific cells, the exact mechanism as to how this occurs has heretofore not been demonstrated.

Think before you drink, says University research

People are being urged to think before they drink as part of a research project aimed at changing people's binge drinking habits.

Model shows how mutation tips biochemistry to cause Alzheimer's

Your fate can be determined by tiny events. Imagine you live in the city and you walk everywhere to get exercise - you are healthy and not afraid of getting mugged. You almost never eat breakfast so you don't stop at the donut shop on the way to work, until one day the manager replaces the girl at the counter with her pretty red-haired younger sister. This seemingly unimportant change in your world is just enough to overcome your ability to resist high-fat temptation. A million donuts later, your cholesterol level surges and then your heart gives out. Curse you, little red-haired girl!

How your heart sounds could tell your heart attack risk

According to scientists in the United States, a doctor may be able to determine a person's risk of having a heart attack just by listening to their heart with a stethoscope.

Australian scientists warn, to avoid cancer keep alcohol to a minimum

Research conducted by scientists at the Cancer Institute has revealed that drinking two units of alcohol on a daily basis significantly increases the risks of developing breast, bowel, throat and mouth cancer.

Discovery of mechanism of action of antibiotic able to reduce neuronal cell death in brain

Virginia Commonwealth University researchers have discovered how an antibiotic works to modulate the activity of a neurotransmitter that regulates brain functions, which eventually could lead to therapies to treat Alzheimer's disease, Huntington's disease, epilepsy, stroke, dementia and malignant gliomas.

microRNAs provide more clues to genetics of schizophrenia

Researchers at Columbia University Medical Center have illuminated a window into how abnormalities in microRNAs, a family of molecules that regulate expression of numerous genes, may contribute to the behavioral and neuronal deficits associated with schizophrenia and possibly other brain disorders.

New theory suggests how hepatitis C may cause rare immune disease

Of the hepatitis alphabet, the C variant may be the nastiest. In 1990, researchers observed that most patients with hepatitis C also develop a rare autoimmune disease called mixed cryoglobulinemia, a condition that frequently leads to cancer, arthritis or both.

Radioactive carbon-14 determines the number of fat cells remains constant in all body types

The radioactive carbon-14 produced by above-ground nuclear testing in the 1950s and '60s has helped researchers determine that the number of fat cells in a human's body, whether lean or obese, is established during the teenage years. Changes in fat mass in adulthood can be attributed mainly to changes in fat cell volume, not an increase in the actual number of fat cells.

Researchers step closer to finding ways to treat type 1 diabetes

Scientists at Washington University School of Medicine in St. Louis working with diabetic mice have examined in unprecedented detail the immune cells long thought to be responsible for type 1 diabetes.

Previously unseen switch regulates breast cancer response to estrogen

A tiny modification called methylation on estrogen receptors prolongs the life of these growth-driving molecules in breast cancer cells, according to research by scientists at Emory University's Winship Cancer Institute.

Discovery of new gene that causes cancer

Researchers at the OU Cancer Institute have identified a new gene that causes cancer. The ground-breaking research appears in Nature's cancer journal Oncogene.

Scientists identify key roadblock to gene expression

A team of scientists has provided, for the first time, a detailed map of how the building blocks of chromosomes, the cellular structures that contain genes, are organized in the fruit fly Drosophila melanogaster. The work identifies a critical stop sign for transcription, the first step in gene expression, and has implications for understanding how the AIDS virus regulates its genes. The findings will be published in the 15 May 2008 issue of the journal Nature
