When it comes to cell entry, being average has its advantages
When it comes to gaining entry into cells, size matters. A team from Brown University and the Max Planck Institute for Metals Research has created a model that explains how viruses and other bioparticles slip inside cells without a special protein coating called clathrin. The secret, it seems, is to be average. Mid-sized nanomaterials ?about 27 to 30 nanometers in diameter, or about 1,000...Sperm stem cells closer to being like embryonic stem cells
New experiments that prevented rat sperm stem cells from changing permanently into sperm have brought researchers one step closer to coaxing such cells to behave like embryonic stem cells, capable of growing into many other types of cells in the body. Researchers at the Cecil H. and Ida Green Center for Reproductive Biology Sciences at UT Southwestern Medical Center devised methods to keep...Progress being made in exploring potential use of stem cells to treat heart disease
Scientists are making headway in exploring the potential future use of stem cells to treat heart disease, according to a review article in the current issue of Nature (June 29, 2006). Authored by Gladstone Institute of Cardiovascular Disease Director Deepak Srivastava, MD, and Gladstone Institutes postdoctoral scholar Kathryn Ivey, PhD, the paper cites a better understanding of the follow...Nanotechnology being used to improve biocompatibility of human prosthetics and implants
As populations of the world age the current trend is that people are not slowing down in their later years. The desire for increased activity among the elderly also means increased demands on medical researchers to come up with better ways to keep them active. In the fields of implants and prosthetics calcium phosphate (CP) coatings on titanium alloy implants are proving their worth in orthopaedi...Here's why Wisconsin's stem cell patents are being challenged
Not only does that make for appealing television drama, but it's pretty...Being proactive with vendors helps healthcare improve IT
Providers are facing that common IT problem: buy or build? After peering...Can we prevent Web 2.0 from being a bubble?
I heard from a number of readers who are more than a little suspicious that Web 2.0 is spelled b-u-b-b-l-e, and who want none of it. As one reader, whom I greatly respect, put it: The industry could use a healthy dose of caution to prevent the heavy Kool-Aid drink...Biodiesel plant being built in DeForest to make alternative fuel
Anamax Corporation broke ground Monday on a new biodiesel plant in DeForest, the largest of its kind in the state at 12,300 square feet and an expected output of 20 million gallons of biodiesel annually. Biodiesel is a biodegradable, non-toxic fuel made from vegetable oil or animal byproducts that can be used to fuel diesel engines either in its pure state or blended with petroleum-based...Healthcare needs of hurricane-hit region being monitored by West Allis company's system
Following the onset of Hurricane Katrina, the U...Are cancer patients being taken for a ride?
One issue that always raises many uncomfortable questions and more troubling answers is that of drug trials. Drug testing has always been an ethical issue and has kindled a lot of heated arguments for and against it. Recent studies have revealed that cancer victims suffer the most when it comes to drug testing when sometimes very toxic new anti cancer drugs are tested on unsuspecting victims in...Nervous disorder being treated
Stiff person syndrome (SPS) causes the muscles in the limbs and body to stiffen up suddenly. Researchers have developed a highly effective treatment for a disorder of the nervous system which can leave people// totally disabled. People with the condition are often too disabled to walk or move, or are afraid to leave the house in case they suffer a spasm and fall. The condition resembl...Benign eye tumors being treated
Researchers at the University of Texas feel that they may have found an effective treatment for a type of non-cancerous eye tumor that threatens clear vision.// Using photodynamic therapy, researchers successfully restored vision in three patients who were suffering from intraocular choroidal hemangiomas, which involved serious retinal detachments. Intraocular choroidal hemangiomas are...Heart disease in women being under-treated
A new study involving 2,763 post menopausal women with heart disease has shown that doctors are under-using aspirin, beta blockers and cholesterol lowering drugs to treat these women even though the medications have been shown to prevent further heart attacks or other heart trouble. Though this study did not look at how often these drugs were offered to men, previous// studies have shown that men...
