Gene therapy converts dead bone graft to new, living tissue

... Schwarz says their appeal has waned because their handling ?keeping them alive and ready to use ?is far harder than Schwarz's viral paste, which can be stored at room temperature and doesn't interfere with the normal grafting surgery. "We're very excited about the prospects of this technology," says Schwarz...

Expression Project for Oncology (expO) completes first phase of standardized gene expression analyses

This enables easier and more cost effective implementation of the new prion reduction filter into established good manufacturing practices. Unlike pathogen inactivation, the new filter does not rely on chemical ad...

Man-made wetland's effectiveness similar to natural marsh

...izer. "As a wetland gets older, it gets better at handling and storing nitrogen," Mitsch said. "The idea is not to overload wetlands in the first place." The three-acre wetland in the study was roughly the size of three football fields and drained a watershed about 14 times that large. It is located in prim...

"By performing genetic analysis on feathers collected at the site, we were able to track the presence or absence of indiv...

Environmental lessons from tsunami as world's coastal population doubles

... the Asian tsunami has given valuable insight into handling extreme coastal disasters - inevitable as the world's coastal population is set to double by 2030 and global warming continues to exacerbate extreme weather conditions.

Agricultural antibiotic use contributes to 'super-bugs' in humans

...s are cross-contaminated because of common, unsafe handling practices. Following ingestion, bacteria occasionally survive the formidable but imperfect gastric barrier to colonize the gut - which in turn may transmit the resistant bacteria to humans. Smith and colleagues say that the transmission of antibioti...

New results validating Pall prion reduction filter disclosed at ISBT Congress

UK sperm donor crisis

... and the EU directive on standards relating to the handling and use of human tissues and cells may also lead to further reductions in donor treatment activity. On the other hand, the demand for donor sperm is likely to increase because of a possible decline in the semen quality in the general UK population." ...

'Dating agency' boosts hunt for disease genes

... "The infrastructure is already up and running for handling patient samples. Now what we've done is to create a sort of scientists' dating agency and shop," explains the Director of the Network's archive, Dr Martin Yuille (University of Manchester). "Vetted scientists can find on the website both data and mat...

The polymer gives the surgical mesh improved handling characteristics that facilitate precise placement during the surgical repair and leave less implant material following the resorption of the coating. Hernias occur when musculature fails and one part of the body protrudes through the resulting gap ...

Study finds how organs monitor themselves during early development

...the fly with its short generation time and ease of handling allows us to address even complicated matters like the development of an organ in a timely and less costly manner than if we used other model organisms such as the mouse, where similar studies would be quite difficult to carry out," says Dr. Lehmann....
