Washington, Apr 23 : Nonsteroidal anti-inflammatory drugs (NSAIDs), such as the pain relievers ibuprofen and naproxen, do not prevent Alzheimer''s disease or other forms of dementia, a new study has shown.

In fact, researchers found that the risk of developing dementia in the study''s very elderly population was 66 percent higher among heavy NSAID users than among people who used little or no NSAIDs.

Washington, April 23 : A team of researchers led by Mayo Clinic scientists has found that hormone therapy use is linked to a significantly lower colorectal cancer risk.

However, the mechanisms for the apparent protective association are still unclear.

The study was designed to look at possible links between estrogen exposure and colon cancer molecular subtypes, to determine how these hormones might function as anti-cancer agents.

Washington, April 23 : Want to shed those extra pounds? Well, then focus more on what you drink than what you eat, a new study suggests.

Liwei Chen, MD, PhD, Assistant Professor of Epidemiology at the LSU Health Sciences Center New Orleans School of Public Health, is the lead author of study, which has shown that weight gain and obesity are more linked to an increase in liquid calories, particularly sugar-sweetened beverages, than calories from solid food.

Washington, April 23 : A team of British scientists has created chemicals that have the potential to kill the most deadly malaria-causing parasite, Plasmodium falciparum - including those resistant to existing drugs.

Researchers at the University of Leeds say that the compounds work by preventing the enzyme dihydroorotate dehydrogenase (DHODH) - essential to the growth of the parasite - from working, which results in its death.

Washington, Apr 23 : Researchers from the Kimmel Cancer Centre at Jefferson have found that vitamin K when combined with sorafenib can help curb pancreatic and primary liver cancers.

According to Dr Brian Carr, professor of Medical Oncology at the Jefferson Medical College of Thomas Jefferson University, vitamin K1 or vitamin K2, combined with sorafenib (Nexavar) each have shown activity against the growth of human cancer cells by inhibiting the extracellular signal-regulated kinase (ERK) pathway.

Washington, Apr 23 : A new study has revealed that common ulcer drugs when combined with an anti-inflammatory medication can offer a potential treatment for Alzheimer's disease.

The research team from the University of British Columbia has found that drugs commonly used to treat ulcers have significant neuroprotective properties, which appear to be enhanced when used in combination with ibuprofen, a widely used anti-inflammatory drug.
