3 new studies reveal added fiber's impact on various health indices

Chicago — (April 22, 2013) – The health benefits of fibre are relatively well known yet average fibre intake around the world continues to be inadequate (1,2). Many diets continue to lack recommended servings of foods naturally high in fibre like fruits, vegetables, nuts, legumes and whole grains resulting in low fibre intake (3). Three new studies contribute to the growing body of evidence for the health benefits of added fibres in the diet.

Rise in sodium intake in US over last decade despite health officials' call for reduction

Chicago — (April 22, 2013) – Sodium intake around the world is well in excess of physiological needs (1) and public health authorities agree that chronic excess sodium intake can increase blood pressure and the risk of heart attack and stroke (2). However, despite recommendations to lower sodium consumption over the last decade, actual intake continues to rise.

Particular DNA changes linked with prostate cancer development and lethality

A new analysis has found that the loss or amplification of particular DNA regions contributes to the development of prostate cancer, and that patients with two of these DNA changes have a high likelihood of dying from the disease. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the study provides valuable information on the genetics of prostate cancer and offers insights into which patients should be treated aggressively.

Positive effect of white button mushrooms when substituted for meat on body weight and composition changes during weight loss an

New research published as an abstract in The FASEB Journal and presented at Experimental Biology 2013 (EB 2013) on Monday, April 22 ties mushrooms to positive health outcomes in the area of weight management. A one-year, randomized clinical trial conducted by researchers at the Weight Management Center at Johns Hopkins Bloomberg School of Public Health and funded by the Mushroom Council found that substituting white button mushrooms for red meat can be a useful strategy for enhancing and maintaining weight loss.1

New research constructs ant family tree

Anyone who has spent time in the tropics knows that the diversity of species found there is astounding and the abundance and diversity of ants, in particular, is unparalleled. Scientists have grappled for centuries to understand why the tropics are home to more species of all kinds than the cooler temperate latitudes on both sides of the equator.

Using nitrous oxide for anesthesia doesn't increase -- and may decrease -- complications and death

San Francisco, CA. (April 22, 2013) – Giving nitrous oxide as part of general anesthesia for noncardiac surgery doesn't increase the rate of complications and death—and might even decrease the risk of such events, according to a pair of studies in the May issue of Anesthesia & Analgesia, official journal of the International Anesthesia Research Society (IARS).

Even a few cigarettes a day increases risk of rheumatoid arthritis

Number of cigarettes smoked a day and the number of years a person has smoked both increase the risk of rheumatoid arthritis (RA), finds research in BioMed Central's open access journal Arthritis Research & Therapy. The risk decreases after giving up smoking but, compared to people who have never smoked, this risk is still elevated 15 years after giving up.

Hundreds of alterations and potential drug targets to starve cancer tumors identified

NEW YORK—A massive study analyzing gene expression data from 22 tumor types has identified multiple metabolic expression changes associated with cancer. The analysis, conducted by researchers at Columbia University Medical Center, also identified hundreds of potential drug targets that could cut off a tumor's fuel supply or interfere with its ability to synthesize essential building blocks. The study was published today in the online edition of Nature Biotechnology.

A scientist on a mission

BOSTON — When thousands of experimental biology researchers gather in Boston this weekend, many of them undoubtedly will be presenting work related to the hunt for the next generation of antibiotics and how to battle back existing and emerging superbugs. But for one scientist from Texas Rio Grande Valley, it's not about what the research of tomorrow holds: It's about the kind of action the people in communities like his need today.

Study: Low-dose aspirin stymies proliferation of 2 breast cancer lines

BOSTON — Regular use of low-dose aspirin may prevent the progression of breast cancer, according to results of a study by researchers at the Veterans Affairs Medical Center in Kansas City, Mo., and the University of Kansas Medical Center.

The study found that aspirin slowed the growth of breast cancer cell lines in the lab and significantly reduced the growth of tumors in mice. The age-old headache remedy also exhibits the ability to prevent tumor cells from spreading.

Structure of cell signaling molecule suggests general on-off switch

DURHAM, N.C. – A three-dimensional image of one of the proteins that serves as an on-off switch as it binds to receptors on the surface of a cell suggests there may be a sort of main power switch that could be tripped. These surface receptors are responsible for helping cells discern light, set the heart racing, or detect pain.

Discovery brings hope of new tailor-made anti-cancer agents

Scientists at the Walter and Eliza Hall Institute and their collaborators have tailor-made a new chemical compound that blocks a protein that has been linked to poor responses to treatment in cancer patients.

Genetics defines a distinct liver disease

Researchers have newly associated nine genetic regions with a rare autoimmune disease of the liver known as primary sclerosing cholangitis (PSC). This brings the total number of genetic regions associated with the disease to 16.

Approximately 70 per cent of people who suffer from PSC also suffer from IBD. The team showed that only half of the newly associated genetic regions were shared with inflammatory bowel disease (IBD). For the first time, this definitively proves that PSC, although genetically related to IBD, is a distinct disease.

A check on tension

April 21, 2013, New York, NY and San Diego Calif. – Ludwig researchers Arshad Desai and Christopher Campbell, a post-doctoral fellow in his laboratory, were conducting an experiment to parse the molecular details of cell division about three years ago, when they engineered a mutant yeast cell as a control that, in theory, had no chance of surviving. Apparently unaware of this, the mutant thrived.

New dietary analysis tool for athletes debuts

Boston, MA— A new website application for athletes called Dietary Analysis Tool for Athletes (D.A.T.A.) has been validated as accurately recording dietary intake based on the 24-hour recall method. "This tool offers sports dietitians and health professionals a new, quick alternative to analyze athletes' dietary intake," said Lindsay Baker, PhD, Principal Scientist, Gatorade Sports Science Institute.
