Ginkgo biloba may prevent brain cell damage after a stroke

Working with genetically engineered mice, researchers at Johns Hopkins have shown that daily doses of a standardized extract from the leaves of the ginkgo tree can prevent or reduce brain damage after an induced stroke.

Testicles may be a source of stem cells

A team of researchers from Britain and Germany have found that a man's testicles may be a source of stem cells.

Battling cancer at the single cell level

New research suggests that the identification and examination of key cell signaling events required for initiation and progression of cancer might be best accomplished at the single cell level. The research, published by Cell Press in the October issue of the journal Cancer Cell, provides new insight that may lead to better diagnosis and treatment of some complex cancers.

New rapid test for rare leukemia

A new twist on a well-known cell sorting technique may allow physicians to diagnose rare leukemias in hours instead of weeks, according to a study by researchers at the Stanford University School of Medicine and UC-San Francisco.

Researchers explore issues related to multiple myeloma treatment

Multiple myeloma (MM) is a cancer of plasma cells that affects approximately 3 in 100,000 people each year. Although there is no cure for this disease, researchers have developed treatments that help relieve pain, control complications, and slow the progress of MM in many patients. Unfortunately, some of the most effective therapies also have toxic side effects that can pose serious health risks and reduce quality of life. In the October issue of Mayo Clinic Proceedings, two articles authored by Mayo researchers address the issue of how to balance the risks and benefits associated with MM treatments.

Helicobacter pylori may help prevent adenocarcinoma, esophageal cancers

Some bacteria may help protect against the development of a type of esophageal cancer, known as adenocarcinoma, according to a new review of the medical literature. These bacteria, which are called Helicobacter pylori, live in the stomachs of humans.

Burst appendix or stomach flu?

A young child arrives at the emergency room after several days of abdominal pain, vomiting, and diarrhea and is sent home with a diagnosis of viral gastritis and treatment for the symptoms. The child seems better for a while, only to return to the ER with worse symptoms and a ruptured appendix, a life-threatening complication of appendicitis.

Disinfectants can make bacteria resistant to treatment

Chemicals used in the environment to kill bacteria could be making them stronger, according to a paper published in the October issue of the journal Microbiology. Low levels of these chemicals, called biocides, can make the potentially lethal bacterium Staphylococcus aureus remove toxic chemicals from the cell even more efficiently, potentially making it resistant to being killed by some antibiotics.

Commonwealth Fund report examines health care proposals of major Presidential candidates

The health care proposal of Democratic presidential nominee Sen. Barack Obama (Ill.) is more likely to improve health care affordability, accessibility, efficiency and quality than the plan of Republican presidential nominee Sen. John McCain (Ariz.), according to a report released on Thursday by the Commonwealth Fund, Reuters/Boston Globe reports.

Many receptor models used in drug design may not be useful after all

It may very well be that models used for the design of new drugs have to be regarded as impractical. This is the sobering though important conclusion of the work of two Leiden University scientists published in Science this week.

Discovery of 100 new antiangiogenesis peptides

Using computer models and live cell experiments, biomedical engineers at the Johns Hopkins University School of Medicine have discovered more than 100 human protein fragments that can slow or stop the growth of cells that make up new blood vessels.

Discovery of important fat precursor cell

To understand where fat comes from, you have to start with a skinny mouse. By using such a creature, and observing the growth of fat after injections of different kinds of immature cells, Rockefeller University scientists have discovered an important fat precursor cell that may in time explain how changes in the numbers of fat cells might increase and lead to obesity.

Exelixis files investigational new drug application for anticancer compound

Exelixis, Inc. announced today that it has submitted an investigational new drug (IND) application to the U.S. Food and Drug Administration for XL888, a novel anticancer compound. XL888 is an orally available small molecule inhibitor of HSP90, which is a chaperone protein that promotes the activity and stability of a range of key regulatory proteins, including kinases.

Scientists identify a molecule that coordinates the movement of cells

Even cells commute. To get from their birthplace to their work site, they sequentially attach to and detach from an elaborate track of exceptionally strong proteins known as the extracellular matrix. Now, in research to appear in the October 3 issue of Cell, scientists at Rockefeller University show that a molecule, called ACF7, helps regulate and power this movement from the inside - findings that could have implications for understanding how cancer cells metastasize.

Vitamin C supplements appear to undercut the effectiveness of cancer drugs

A new study by scientists in the United States has revealed that vitamin C may blunt the effectiveness of chemotherapy treatment.

Molecule provides new understanding of cause of colon cancer

Scientists investigating a molecule known to play a key role in causing colon cancer have made a series of ground-breaking discoveries that could have major implications for future treatment of the disease, responsible for 655,000 deaths worldwide per year. Their findings are published in the journal Cancer Research.
