Women without HOXA13 gene mutation need not be subjected to X-rays

Hugh S. Taylor, M.D., professor in the Department of Obstetrics, Gynecology & Reproductive Sciences at Yale, and colleagues have found that women without mutations of the HOXA13 gene do not need to be subjected to x-rays and other tests for a rare condition called hand-foot genital syndrome. The research is presented at the American Society for Reproductive Medicine (ASRM) scientific meeting in Atlanta, Georgia, October 17-21.

Regulatory differences between mother and daughter cells shed new light on cell division

When mother and daughter cells are created each time a cell divides, they are not exactly alike. They have the same set of genes, but differ in the way they regulate them. New research now reveals that these regulatory differences between mother and daughter cells are directly linked to how they prepare for their next split.

Small mechanical force induces strong biological responses in embryonic stem cells

Applying a small mechanical force to embryonic stem cells could be a new way of coaxing them into a specific direction of differentiation, researchers at the University of Illinois report. Applications for force-directed cell differentiation include therapeutic cloning and regenerative medicine.

Scientists find mechanism that protects neurons from calcium overload

Tsuruta et al. find that a lipid kinase directs a voltage-gated calcium channel's degradation to save neurons from a lethal dose of overexcitement. The study appears in the October 19, 2009 issue of the Journal of Cell Biology (www.jcb.org).

Tel Aviv University develops scaffold to regenerate damaged bones and tissues

Mother Nature has provided the lizard with a unique ability to regrow body tissue that is damaged or torn ― if its tail is pulled off, it grows right back. She has not been quite so generous with human beings. But we might be able to come close, thanks to new research from Tel Aviv University.

Researchers develop new technique to study the mechanisms behind diseases in more detail

Researchers have previously been able to analyse which sugar structures are to be found on certain proteins, but not exactly where on the protein they are positioned. This is now possible thanks to a new technique developed at the Sahlgrenska Academy at the University of Gothenburg, Sweden.

NIH funded regeneration research to be presented at Society for Neuroscience annual meeting

Biologists long have marveled at the ability of some animals to re-grow lost body parts. Newts, for example, can lose a leg and grow a new one identical to the original. Zebrafish can re-grow fins.

Antioxidant extracts of G.biloba leaves may protect cells from radiation damage

Antioxidant extracts of the leaves of the Gingko biloba tree may protect cells from radiation damage, according to a study published in the International Journal of Low Radiation. The discovery may one day be used to help reduce side effects in cancer patients undergoing radiotherapy.

Scientists find cause for lupuslike disease in mice

Macrophages, the scavenger cells of the body's immune system, are responsible for disposing of dying cells. Stanford University School of Medicine researchers have identified one pathway in this important process in mice that, if disrupted, causes a lupuslike autoimmune disease.

Metabolic master switch sets the biological clock in body tissues

Our body's activity levels fall and rise to the beat of our internal drums-the 24-hour cycles that govern fundamental physiological functions, from sleeping and feeding patterns to the energy available to our cells. Whereas the master clock in the brain is set by light, the pacemakers in peripheral organs are set by food availability. The underlying molecular mechanism was unknown.
