Prothesis made of nanocompound material may last more than 150 years

Current body protheses do not last more than 10-15 years. After this time, the operation has to be repeated in order to change prothesis. It is usually problematic as, in general, it is elderly people that use the procedure. Researcher Nere Garmendia, based in the Basque city of Donostia-San Sebasti-n, has just published her PhD, a thesis which may well mean the first step to solving this problem. According to Ms Garmendia, using a ceramic material called zirconia (Zr02), carbon nanotubes and nanoparticles of zirconia, a prothesis that will last more than 150 years can be produced.

DSAEK cornea transplant offers potential long-term benefits

One year post-surgery, patients who underwent Descemet's stripping automated endothelial keratoplasty experienced greater cell loss overall compared to those who underwent penetrating keratoplasty, according to a new analysis of data collected from the Cornea Donor Study Investigator Group's 2008 Specular Microscopy Ancillary Study.

Researchers measure diffusion coefficient of a protein in a primary cilium

A team of researchers led by Peter Calvert (SUNY Upstate Medical University) has, for the first time, measured the diffusion coefficient of a protein in a primary cilium and in other major compartments of a highly polarized cell. The study appears in the March issue of the Journal of General Physiology.

Research paves way for building tabletop X-ray laser that can be used for high-resolution imaging

For nearly half a century, scientists have been trying to figure out how to build a cost-effective and reasonably sized X-ray laser that could, among other things, provide super high-resolution imaging. And for the past two decades, University of Colorado at Boulder physics professors Margaret Murnane and Henry Kapteyn have been inching closer to that goal.

Kinesin protein motor shuttles cargo within cells and helps cells divide by rocking like a seesaw

Life's smallest motor, a protein that shuttles cargo within cells and helps cells divide, does so by rocking up and down like a seesaw, according to research conducted by scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and Brandeis University.

Calcium waves could be relevant for understanding the origin of Alzheimer's disease

New insights on what causes Alzheimer's disease could arise from a recent discovery made by bioengineers from the University of California, San Diego. The finding concerns the infamous amyloid beta peptides (Aβ)-fragments of which form plaques thought to play a role in Alzheimer's disease.

New research suggests closantel drug may be useful in combating river blindness

Scientists at The Scripps Research Institute have discovered a potential new use for the drug closantel, currently the standard treatment for sheep and cattle infected with liver fluke. The new research suggests that the drug may be useful in combating river blindness, a tropical disease that is the world's second leading infectious cause of blindness for humans.

New research shows tumor suppressor p53 prevents cancer progression in cells

Cells missegregate a chromosome approximately once every hundred divisions. But don't be too alarmed: new research in the Journal of Cell Biology shows that the tumor suppressor p53 limits the growth of cells with incorrect numbers of chromosomes and prevents their progression toward cancer.

Noninvasive optical imaging probes to determine amount and type of cell death in tumors

For quite some time, the "Holy Grail" in medical imaging has been the development of an effective method to image cell death as a means to intervene early in diseases and rapidly determine the effectiveness of treatments. A new paper by researchers at the University of Notre Dame and the Washington University School of Medicine describes important progress in using a synthetic probe to target dead and dying cells in mammary and prostate tumors in living animals.

Researchers challenge prevailing belief about role of protein in abnormal cell proliferation

In a study to be published this week, a research team is challenging a prevailing belief about the behavior of a human protein linked to the formation of cancer, possibly breathing new life into the search for therapies that will inhibit that protein from "turning on" genes involved in abnormal cell proliferation.
