Why certain ovarian cancers develop resistance

Why certain ovarian cancers develop resistance
A team of scientists led by Fred Hutchinson Cancer Research Center has identified a new mechanism that explains why some recurrent ovarian tumors become resistant to therapy with usually used platinum-based chemotherapy drugs such as cisplatin and carboplatin. They describe their research online Feb. 10 in the journal Nature. While these findings are based on the study of ovarian-cancer cells from women with inherited mutations in the BRCA2........Go to the Ovarian cancer blog (Added on 2/10/2008 9:47:52 PM)

Artificial sweeteners linked to weight gain

Artificial sweeteners linked to weight gain
Want to lose weight" It might help to pour that diet soda down the drain. Scientists have laboratory evidence that the widespread use of no-calorie sweeteners may actually make it harder for people to control their intake and body weight. The findings are reported in the recent issue of Behavioral Neuroscience, which is published by the American Psychological Association (APA).

PET Outperforms CT In Malignant Lung Nodules

PET Outperforms CT In Malignant Lung Nodules
Scientists involved in a large, multi-institutional study comparing the accuracy of positron emission tomography (PET) and computed tomography (CT) in the characterization of lung nodules observed that PET was far more reliable in detecting whether or not a nodule was cancerous. "CT and PET have been widely used to characterize solitary pulmonary nodules (SPNs) as non-malignant or cancerous," said James W.

Dairy Products For Healthy Gums

Dairy Products For Healthy Gums
Consumers have long known that including dairy in their diets can help maintain healthy bones and even help promote weight loss. However, a recent study reported in the recent issue of the Journal of Periodontology, the official publication of the American Academy of Periodontology (AAP), demonstrated that routine intake of dairy products may also help promote periodontal health.

Key interaction in cholesterol regulation

Key interaction in cholesterol regulation
Scientists at UT Southwestern Medical Center have determined the specific way in which a destructive protein binds to and interferes with a molecule that removes low-density lipoproteins (LDL), the so-called bad cholesterol, from the blood. The practical benefit of this finding is that we can now search for new ways to lower cholesterol by designing targeted antibodies to disrupt this interaction, said Dr. Jay Horton, professor of internal........Go to the Heart-watch-blog (Added on 2/4/2008 10:23:42 PM)

BRCA1 mutation linked to breast cancer stem cells
A new study may explain why women with a mutation in the BRCA1 gene face up to an 85 percent lifetime risk of breast cancer. Scientists from the University of Michigan Comprehensive Cancer Center observed that BRCA1 plays a role in regulating breast stem cells, the small number of cells that might develop into cancers.

Sugary soft drinks linked to increased risk of gout
Consumption of sugar sweetened soft drinks and fructose is strongly linked to an increased risk of gout in men, finds a study published on bmj.com today. Gout is a joint disease which causes extreme pain and swelling. It is most common in men aged 40 and older. It is caused by excess uric acid in the blood (hyperuricaemia) which leads to uric acid crystals collecting around the joints. In the United States, levels of gout have doubled........Go to the Society medical news blog (Added on 1/31/2008 10:13:51 PM)

Last week, the UK health secretary declared that we are in a grip of an obesity epidemic, but does the evidence stack up? Scientists in this weeks BMJ debate the issue.
