Heart regenerates after infarction

Up until today scientists assumed that the adult heart is unable to regenerate. Now, researchers and cardiologists from the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch and the Charité - Universitätsmedizin Berlin (Germany) have been able to show that this dogma no longer holds true.

Exercise suppresses appetite by affecting appetite hormones

A vigorous 60-minute workout on a treadmill affects the release of two key appetite hormones, ghrelin and peptide YY, while 90 minutes of weight lifting affects the level of only ghrelin, according to a new study.

Enzyme that mutates antibodies also targets cancer-causing gene

The human immune system is in a perpetual state of self-experimentation. It expertly mutates and shuffles the DNA of its own cells to evolve new defenses against the vast array of microbes that try to invade our bodies.

Researchers capture never before seen undulations of "dancing chromosomes"

The rhythm of life may beat far deeper than anyone previously thought. And it may gyrate and pulse in a way that rivals the sensuous choreography of "Dirty Dancing."

Researchers create tiny, implantable device that captures and kills cancer cells in the bloodstream

In a new tactic in the fight against cancer, Cornell University researcher Michael King has developed what he calls a lethal "lint brush" for the blood -- a tiny, implantable device that captures and kills cancer cells in the bloodstream before they spread through the body.

Trial looks at new treatment for solid cancer tumors and non-Hodgkin's lymphoma

Researchers at The Cancer Institute of New Jersey (CINJ) have opened a clinical trial, which aims to evaluate a new treatment for solid cancer tumors and non-Hodgkin's lymphoma (NHL) in combination with a chemotherapy agent called cyclophosphamide.

Scientists show that HIV's evolution in the body does not occur at a constant rate

HIV is so deadly largely because it evolves so rapidly. With a single virus as the origin of an infection, most patients will quickly come to harbor thousands of different versions of HIV, all a little bit different and all competing with one another to most efficiently infect that person's cells. Its rapid and unique evolution in every patient is what allows HIV to evade the body's defenses and gives the virus great skill at developing resistance to a pantheon of antiviral drugs.

An evidence-based approach to theories of medical decision making and health

As a way to help both the sick and their medical care providers to make the best healthcare decisions possible, a special section of the current November/December 2008 issue of Medical Decision Making examines three current evidenced-based theories that can help to improve assessments, assist in prevention programs, and help with intervention efforts.

Enzyme that mutates antibodies also targets a cancer-causing oncogene

Rockefeller University scientists have discovered that the same enzyme that enables the immune system's defensive creativity is also responsible for a particular genetic malfunction - a translocation of one piece of DNA to the wrong chromosome - that causes Burkitt's lymphoma.

Mathematical models of adaptive immunity

More than five million people die every year from infectious diseases, despite the availability of numerous antibiotics and vaccines. The discovery of penicillin to treat bacterial infections, along with the development of vaccines for previously incurable virus diseases such as polio and smallpox, achieved great reductions in mortality during the mid-20th century.
