PRIMARY PULMONARY HYPERTENSION GENE DISCOVERED

The discovery of the gene associated with the inherited form of primary pulmonary hypertension (PPH) by Drs. Jane H. Morse of Columbia University and James A. Knowles of the Columbia Genome Center is indeed a major breakthrough. Their study, funded in part by th...

Blood Cells Capable of Regenerating Liver

...erated using stem cells from blood -- an important discovery that means patients may be able to grow their own liver transplants using bone marrow. This adds to a growing body of evidence that stem cells, known as "master cells" because they can produce a variety of different kinds of cells, might one day be m...

New Way to "See" Genes, Evaluate Effectiveness of Gene Therapies Discovered

...her illnesses, such as cardiovascular disease. The discovery is outlined in the August 2000, issue of the journal Nature Medicine. UCLA researchers plan to test the tracking system in prostate cancer patients within a year, and are working with researchers at other institutions to help them evaluate other gene...

El Ni?o cycles linked to cholera outbreaks

...itary conditions and disease susceptibility. The discovery of a remote link between El Ni?o events and cholera outbreaks comes at a time when some ecologists, are predicting major increases in disease and death as global climate change provides ideal conditions for disease-causing organisms. Yet, the El Ni?o...

Gene clue to antibiotics

...antibiotic synthesis. This opens up the way to the discovery of many new antibiotics. Streptomyces also makes potential anti-cancer drugs, and immune-suppressants. Incidentally Streptomyces is also quite similar to the microbe that causes tuberculosis. So this research may reveal insights into the biology of...

Fingerprinting prostate cancer

...ories were checked. The researchers say that the discovery of prostate cancer's molecular fingerprint could lead to many new diagnostic tests. These could offer more to the patient than the current PSA (prostate specific antigen) test and can be used as a useful diagnostic tool....

Snake venom a treatment for digestive disease

All the more bad

...protects against heart disease in their blood. The discovery could help explain why smokers have more than twice the risk of heart attacks than non-smokers. Paraoxonase is a enzyme which helps to prevent fatty deposits building up and blocking the blood vessels. A team of Swiss researchers examined 367 peopl...

Common contraception

The discovery is reported by Dr David Clapham, from the Howard Hughes Medical Institute, and colleagues from Harvard Medical School."This is the only protein// I've ever seen that localises to only one tissue," said Dr Clapham. "We looked carefully through at lea...

New Way To Treat Lupus

...ow the immune system goes awry in the disease//--a discovery scientists say could lead to better, more targeted treatments for lupus in the next few years. The new study suggests how this misguided immune system attack unfolds. Drugs that suppress the immune system are already part of lupus treatment, but th...

Syphilis uncovered
