Drug Can Quickly Mobilize An Army Of Cells To Repair Injury
22.9.2006 | Press monitoring
To speed healing at sites of injury - such as heart muscle after a heart attack or brain tissue after a stroke - doctors would like to be able to hasten the formation of new blood vessels. One promising approach is to "mobilize" patients' blood vessel-forming cells, called angiogenic cells, so these cells can reach the injured ar...

BRUSSELS (Reuters) - An unauthorized genetically modified (GMO) rice has found its way into the European Union's retail food sector and appeared for sale at branches of discount supermarket Aldi, environment group Greenpeace said on Monday.
'Crabby' Compound That Skewers Bacteria Could Prevent Medical Implant Infections
21.9.2006 | Press monitoring
A chemical compound found in crabs and shrimp that has long been known to have certain medicinal value also can act like a "bed of nails," fending off microbes seeking to colonize wound dressings, catheters and other implantable medical devices, according to Montana State University researchers. Using the compound to coat these medical devices,...
Mayo Researchers Discover HIV Dependence On A Human Protein
20.9.2006 | Press monitoring
Mayo Clinic virologists have discovered that a specific human protein is essential for HIV to integrate into the human genome. Their findings show that when HIV inserts itself into a chromosome, a key step that enables it to establish a "safe haven," it requires a specific protein -- LEDGF/p75 (p75). This protein forms a molecular tether between...
Explosives At The Nanoscale With 'World's Smallest Controlled Heat Source'
20.9.2006 | Press monitoring
Using nanometer scale analysis techniques and quantities too small to explode, researchers have mapped the temperature and length-sale factors that make energetic materials – otherwise known as explosives – behave the way they do.
Microbes can clean up toxic waste dumps
19.9.2006 | Press monitoring
Microbes with a taste for toxic waste may hold the solution to cleaning up contaminated industrial sites and poisoned waterways across the globe, saving billions of dollars in cleanup bills, an Australian scientist said.
Bacteria make the rotor go round
19.9.2006 | Press monitoring
Scientists in Japan have used gliding bacteria to turn a microscale rotor made of silicon dioxide. The motor device could ultimately be used to drive microrobots.
STM switches chlorophyll molecules
19.9.2006 | Press monitoring
Researchers from Ohio University, US, have used a scanning tunnelling microscope (STM) to change the conformation of molecules of chlorophyll-a. By injecting a single electron the scientists were able to switch the molecules between each of four states.
'Molecular computers' act as tiny ID tags
19.9.2006 | Press monitoring
Molecules capable of basic logic operations have been developed that could serve as tiny ID tags for identifying individual cells or nano-devices. The technique, called molecular computational identification (MCID), could produce tens of millions of unique tags.
