Molecular fingerprint of cocaine addiction revealed

The first large-scale analysis of proteins in the brains of monkeys addicted to cocaine reveals new information on how long-term cocaine use changes the amount and activity of various proteins affecting brain function.

RNA toxicity contributes to neurodegenerative disease

Expanding on prior research performed at the University of Pennsylvania, Penn biologists have determined that faulty RNA, the blueprint that creates mutated, toxic proteins, contributes to a family of neurodegenerative disorders in humans.

Increased screening may better predict those at higher risk for heart disease

Adding noninvasive imaging to current risk-assessment protocols may identify more people who are at risk of developing heart disease, UT Southwestern Medical Center researchers have found.

Warning about the danger of yet another bird flu virus

Scientists in the United States have identified a second H strain of bird flu that could cause a pandemic, they say the H5N1 strain of bird flu currently circulating the globe is not the only cause for concern.

Blood cholesterol levels predict risk of heart disease due to hormone therapy

A new analysis of a subgroup of participants in the Women's Health Initiative (WHI) hormone therapy clinical trials suggests that healthy, postmenopausal women whose blood cholesterol levels are normal or lower are not at increased, short-term risk for heart attack when taking hormone therapy.

New cheaper method for mapping disease genes

Scientists at the Swedish medical university Karolinska Institutet have developed a new DNA-sequencing method that is much cheaper than those currently in use in laboratories. They hope that this new method will make it possible to map disease genes in large patient groups, which in turn can mean quicker breakthroughs for new treatments for a wide variety of diseases.

New treatments for viral and other diseases by blocking genes

The elusive goal of developing effective treatments for viral diseases such as AIDS and influenza has been brought closer by dramatic progress in the ability to interfere with viral genetic machinery. The stage was set for a coordinated European effort to accelerate research and stimulate development of new treatments against viral diseases at a recent research conference organised by the European Science Foundation (ESF).

Bone repair using patient's stem cells comes closer

Hitherto it has been difficult to induce adult human stem cells to produce bone, e.g. in order to repair bone tissue. Researchers at the University of Twente have shown that if the enzyme PKA is previously activated in the stem cells in the lab, following implantation this results in substantial bone formation.

Alpha1-antitrypsin deficiency associated with increased risk of lung cancer

Carriers of a common genetic disorder previously linked to lung disease may have a 70-percent to 100-percent increased risk of lung cancer, according to a report in the May 26 issue of Archives of Internal Medicine

Monitoring blood flow helps improve prostate biopsies

Using a special ultrasound technique to spot areas of blood flow in the prostate gland may substantially reduce the number of unnecessary biopsies, according to a new study by urologists and radiologists at the Jefferson Prostate Diagnostic Center and the Kimmel Cancer Center at Jefferson in Philadelphia.

Discovery on how an Helicobacter pylori toxin gets into cells

Helicobacter pylori is one tough bug. It can survive in the human stomach, a zone with a pH somewhere between that of lemon juice and battery acid. Now researchers have discovered how an H. pylori toxin gets into cells, a feat that helps the bacterium live in one of the most inhospitable environments in the body

Researchers find multiple cancer genes cooperate to cause malignant cell transformation

Pinpointing new targets for cancer treatments is as difficult as finding a needle in a haystack, yet a University of Rochester team has discovered an entire novel class of genes they believe will lead to a greater understanding of cancer cell function and the next generation of effective and less harmful therapies for patients.
