Research shows brain cells move like a two-stroke engine

Following the often-quoted advice of Yogi Berra — "You can observe a lot by just watching" — Rockefeller University scientists show that nerve cells in the developing brains of humans and other mammals move in a two-part "step" led by a structure within the cell called the centrosome.

Low dose aspirin dosages trigger the body to generate its own anti-inflammatory compounds

Researchers at Brigham and Women’s Hospital (BWH) and colleagues have demonstrated for the first time in humans in a randomized clinical trial that low-dose aspirin - dosages equivalent to one baby aspirin (81 mg) - trigger the body to generate its own anti-inflammatory compounds that help fight unwanted inflammation.

Research findings represents a step toward understanding the machinery by which the brain processes decisions

While neurobiologists have long suspected that certain regions of the brain are specifically involved in making decisions, the challenge has been to develop rigorous laboratory behavioral experiments that could pinpoint those areas.

Melanin is not only good for you, it also can be bad

Blondes and redheads not only are more susceptible to skin cancer, but the source of their skin and hair pigmentation, melanin, actually magnifies the damaging effects of ultraviolet (UV) rays, according to a study published online this week in the Proceedings of the National Academy of Sciences.

Technique for genetically modifying blood stem cells brings cure for blood diseases closer

The condition of mice with a genetic blood disease called beta-thalassemia improved significantly following treatment of their blood forming cells with a gene that enabled them to produce the type of hemoglobin normally found only in the fetus.

Estrogen protects male rats from aortic aneurysms

When it comes to abdominal aortic aneurysms – life-threatening bulges or weak areas in the main artery feeding blood to the lower half of the body – new U-M research shows that it is definitely better to be female.

New research points to potential new treatments for sickle cell disease

New research from the University of North Carolina at Chapel Hill reveals why red blood cells from people with sickle cell disease are stickier than healthy red cells, pointing the way to potential new treatments for sickle cell disease.

New study offers rare glimpse of how the smallpox virus attacks its victims

Results of a new study in monkeys offer scientists a rare glimpse of how, on a molecular level, the smallpox virus attacks its victims. The findings shed light on how the virus caused mass death and suffering, and will help point the way to new diagnostics, vaccines and drugs that would be needed in the event of a smallpox bioterror incident.

A change in the national polio vaccination policy has led to the elimination of vaccine-associated paralytic poliomyelitis

The researchers found that from 1990 through 1999, 61 cases of paralytic polio were reported; 59 (97 percent) of these were VAPP (1 case per 2.9 million OPV doses distributed), 1 case was imported, and 1 case was indeterminate.

A unique new non-invasive technique for high resolution optical imaging of the eye

The technique, pioneered by the University of Kent, is funded by the Toronto-based company, Ophthalmic Technology Inc (OTI). The University’s Applied Optics Group is currently working with university hospitals in New York (USA), Osaka (Japan), Asahikawa (Japan), Amsterdam (Netherlands) and Milan (Italy) to carry out preliminary clinical trials.

Researchers identify common mutation in T-cell acute lymphocytic leukemia

Researchers at Brigham and Women’s Hospital (BWH) and Dana-Farber Cancer Institute (DFCI) have made a breakthrough discovery, identifying a common mutation in T-cell acute lymphocytic leukemia (T-ALL), an important form of cancer in children and adolescents.

Study sheds light on events orchestrating the changes when mammalian eggs are fertilized and become embryos

A new study sheds light on events orchestrating the changes when mammalian eggs are fertilized and become embryos. Researchers have discovered that expression of genes in mouse eggs and very early embryos is activated in part by regions of DNA called retrotransposons, which may have originated from retroviruses.

Signaling pathway could be a valuable target for future drug therapies against systemic lupus erythematosus

Medical investigators at the Hospital for Special Surgery have identified an important new signaling pathway they believe could be a valuable target for scientists to aim at with future drug therapies that might one day reverse diseases such as systemic lupus erythematosus, according to a recent article published in “Nature Immunology.”
