Purple sweet potato means increased amount of anti-cancer components

A Kansas State University researcher is studying the potential health benefits of a specially bred purple sweet potato because its dominant purple color results in an increased amount of anti-cancer components.

K-State’s Soyoung Lim, doctoral student in human nutrition, Manhattan, is working with George Wang, associate professor of human nutrition at K-State, to understand the pigment effects of a Kansas-bred purple sweet potato on cancer prevention.

Aerobic activity may keep the brain young

New research from the University of North Carolina at Chapel Hill School of Medicine finds that aerobic activity may keep the brain young.

In the study published July 9 in the American Journal of Neuroradiology, physically active elderly people showed healthier cerebral blood vessels.

Extending the shelf life of antibody drugs

A new computer model developed at MIT can help solve a problem that has plagued drug companies trying to develop promising new treatments made of antibodies: Such drugs have a relatively short shelf life because they tend to clump together, rendering them ineffective.

Scientists find key culprits in lupus

The more than 1.5 million Americans with systemic lupus erythematosus (or lupus) suffer from a variety of symptoms that flare and subside, often including painful or swollen joints, extreme fatigue, skin rashes, fever, and kidney problems. Researchers at The Scripps Research Institute have now identified the main trigger for the development of this disease.

Neural stem cell differentiation factor discovered

Neural stem cells represent the cellular backup of our brain. These cells are capable of self-renewal to form new stem cells or differentiate into neurons, astrocytes or oligodendrocytes. Astrocytes have supportive functions in the environment of neurons, while oligodendrocytes form the myelin layer around axons in order to accelerate neuronal signal transmission.

But how does a neural stem cell „know” which way it is supposed to develop? On the molecular level receptors of the Notch family play a significant role in this process. So far, only stimulating extracellular ligands of Notch receptors had been described. Biochemists of Goethe University Medical School now describe a long time assumed but not yet identified soluble Notch inhibitor.

Daily sex helps to reduce sperm DNA damage and improve fertility

Amsterdam, The Netherlands: Daily sex (or ejaculating daily) for seven days improves men’s sperm quality by reducing the amount of DNA damage, according to an Australian study presented today (Tuesday) to the 25th annual meeting of the European Society of Human Reproduction and Embryology in Amsterdam.

Helmholtz Zentrum München – German Research Center for Environmental Health

Scientists from Texas are batty over a new discovery which could lead to the single most important medical breakthrough in human history—significantly longer lifespans. The discovery, featured on the cover of the July 2009 print issue of The FASEB Journal (http://www.fasebj.org), shows that proper protein folding over time in long-lived bats explains why they live significantly longer than other mammals of comparable size, such as mice.
