Pepper and halt: Spicy chemical may inhibit gut tumors

Posted: 03 Aug 2014 02:00 PM PDT

Researchers at the University of California, San Diego School of Medicine report that dietary capsaicin - the active ingredient in chili peppers - produces chronic activation of a receptor on cells lining the intestines of mice, triggering a reaction that ultimately reduces the risk of colorectal tumors. The findings are published in the August 1, 2014 issue of The Journal of Clinical Investigation.

Rosemary and oregano contain diabetes-fighting compounds

Posted: 24 Jul 2014 12:00 AM PDT

The popular culinary herbs oregano and rosemary are packed with healthful compounds, and now lab tests show they could work in much the same way as prescription anti-diabetic medication, scientists report. In their new study published in ACS' Journal of Agricultural and Food Chemistry, they found that how the herbs are grown makes a difference, and they also identified which compounds contribute the most to this promising trait.

Niacin too dangerous for routine cholesterol therapy

Posted: 21 Jul 2014 02:00 AM PDT

After 50 years of being a mainstay cholesterol therapy, niacin should no longer be prescribed for most patients due to potential increased risk of death, dangerous side effects and no benefit in reducing heart attacks and strokes, writes Northwestern Medicine® preventive cardiologist Donald Lloyd-Jones, M.D., in a New England Journal of Medicine editorial.

Taking B vitamins won't prevent Alzheimer's disease

Posted: 16 Jul 2014 02:00 AM PDT

Taking B vitamins doesn't slow mental decline as we age, nor is it likely to prevent Alzheimer's disease, conclude Oxford University researchers who have assembled all the best clinical trial data involving 22,000 people to offer a final answer on this debate. High levels in the blood of a compound called homocysteine have been found in people with Alzheimer's disease, and people with higher levels of homocysteine have been shown to be at increased risk of Alzheimer's disease.

Is the next 'new' cancer drug already in your medicine cabinet?

Posted: 30 Jun 2014 02:00 PM PDT

It turns out that the same types of drugs that help reduce watery eyes and runny noses during allergy season might also help ward off tumors too. A new research report appearing in the July 2014 issue of The Journal of Leukocyte Biology suggests that antihistamines may have significant anti-cancer properties as they interfere with the function of a type of cell that is known to reduce the body's ability to fight tumors (called "myeloid derived suppressor cells").

Anti-diabetic drug slows aging and lengthens lifespan

Posted: 03 Jun 2014 02:00 PM PDT

A study by Belgian doctoral researcher Wouter De Haes (KU Leuven) and colleagues provides new evidence that metformin, the world's most widely used anti-diabetic drug, slows ageing and increases lifespan. In experiments reported in the journal Proceedings of the National Academy of Sciences, the researchers tease out the mechanism behind metformin's age-slowing effects: the drug causes an increase in the number of toxic oxygen molecules released in the cell and this, surprisingly, increases cell robustness and longevity in the long term.

Aspirin can reduce colorectal cancer risks for those with specific gene

Posted: 23 Apr 2014 02:00 PM PDT

The humble aspirin may have just added another beneficial effect beyond its ability to ameliorate headaches and reduce the risk of heart attacks: lowering colon cancer risk among people with high levels of a specific type of gene. The extraordinary finding comes from a multi-institutional team that analyzed data and other material from two long-term studies involving nearly 128,000 participants.
