Japanese Mushroom enzyme may revolutionize protein research

MushroomWashington, May 5 : Utrecht University researchers studying Japanese mushroom Grifola frondosa have achieved a major breakthrough that may help simplify the study of proteins lying at the root of various diseases like cancer and diabetes.

Lead researcher Albert Heck says that it is possible to identify proteins without knowing the organism's genetic composition by using an enzyme of the Japanese mushroom, which is also known as Maitake or dancing mushroom.

Vaginal bleeding after menopause could be a sign of cancer

Munich - Women who experience unexpected vaginal bleeding after menopause should always consult their gynaecologist, said Germany's professional association for gynaecologists.

Vaginal bleeding after menopause could indicate cancer of the uterus, according to the Munich-based association.

Women not yet in menopause who experience unusually heavy or irregular periods, discharge and abdominal pain could have a tumour, the association added.

Exposure to pesticides linked to increase in testicular cancers risk

PesticideWashington, Apr 30 : A recent study has stated that men exposed to organochlorine pesticide metabolites, such as DDE, are more prone to developing testicular germ cell tumours.

Earlier studies have revealed that persistent exposure to organochlorine pesticides may increase the risk for some types of testicular cancer, but no evidence was found to establish the observation.

Outdated breast cancer treatment costs lives

Cologne, Germany - Breast CancerOne in eight women in Germany is diagnosed with breast cancer in the course of her life. With some 57,000 new cases each year, mastocarcinoma is thus the most common form of cancer among women. And the disease is still fatal 40 per cent of the time.

Many patients could live longer, though, if only they received more effective treatment via the latest medical knowledge and improved interdisciplinary cooperation among doctors.
