White Bread Helps Boost Some of the Gut’s ‘Good’ Microbes

July 2, 2014 1:11 pm | News | Comments

White-bread lovers take heart. Scientists are now reporting that this much-maligned food seems to encourage the growth of some of our most helpful inhabitants — beneficial gut bacteria. In addition to this surprising find, their study also revealed that when looking at effects of food on our “microbiomes,” considering the whole diet, not just individual ingredients, is critical.

Cellular Gates for Sodium, Calcium Controlled by Ancient Element

July 2, 2014 9:46 am | News | Comments

Researchers have spotted a strong family trait in two distant relatives: The channels that permit entry of sodium and calcium ions into cells turn out to share similar means for regulating ion intake, they said.            

Treasure Trove of Genes Key to Kidney Cancer

July 2, 2014 9:24 am | Videos | Comments

A genomic analysis of clear cell renal cell carcinoma (ccRCC), the most common form of kidney cancer, from 72 patients has uncovered 31 genes that are key to development, growth and spread of the cancer, according to researchers.      

Lead in Kids’ Blood Linked to Behavioral, Emotional Issues

July 2, 2014 9:17 am | News | Comments

Emotional and behavioral problems show up even with low exposure to lead, and as blood lead levels increase in children, so do the problems, according to new research.                       

NIH Creates Network to Tackle Mysterious Diseases

July 1, 2014 4:20 pm | by Lauran Neergaard - AP Medical Writer - Associated Press | News | Comments

The government is expanding its "mystery disease" program, funding a network at six universities around the country to help diagnose patients with diseases so rare they've been told they're undiagnosable. The National Institutes of Health has evaluated hundreds of these cold-case patients in its campus research hospital as part of a pilot program since 2008. Demand is so great, there's a waiting list.

Marrow Transplants Can Reverse Adult Sickle Cell

July 1, 2014 4:20 pm | by Lindsey Tanner - AP Medical Writer - Associated Press | News | Comments

Bone marrow transplants can reverse severe sickle cell disease in adults, a small study by government scientists found, echoing results seen with a similar technique used in children. The researchers and others say the findings show age need not be a barrier and that the technique may change practice for some adult patients when standard treatment fails.

Stem Cells Halt MS for Two Years

July 1, 2014 12:07 pm | by Cynthia Fox | Articles | Comments

At 21, MS had Jennifer Molson “wheelchair bound.” But since her stem cell transplant, she has worked, driven, danced at her own wedding. The story had a room of 1,000 professional stem cell scientists sniffling loudly at the International Society for Stem Cell Research (ISSCR) meeting—said sniffling reaching a crescendo when the quiet, pretty Molson concluded: “I’m living proof stem cells can save lives.”

Four in Ten Pancreatic Cancers Could be Prevented by Lifestyle Changes

July 1, 2014 11:49 am | News | Comments

Almost 40 percent of pancreatic cancers– one of the deadliest forms of cancer– could be avoided in the UK through maintaining a healthy weight and not smoking, according to new research.                   

Unsuspected Aspect of Immune Regulation Revealed

July 1, 2014 11:35 am | News | Comments

A discovery by Australian immunologists uncovered an additional role for antibody-making ‘B cells.’ The finding shows that B cells also participate in the development of ‘regulatory T cells.’ Until now, the only non-thymic cells known to educate the regulators were dendritic cells, which travel to the thymus to deliver ‘antigen’, samples of substances toxic to the body. We now know that B cells can do the same thing.

Cancer Risk: Aspirin and Smoking Affect Aging of Genes

July 1, 2014 11:23 am | News | Comments

The risk of developing cancer increases with age. Factors like smoking and regular aspirin use also affect the risk of cancer—although in the opposite sense. Researchers from the University of Basel were now able to show that aspirin use and smoking both influence aging processes of the female genome that are connected to colorectal cancer.
