Bioartificial kidney under study at MCG

...u have renal failure in the ICU, your mortality is extremely high," Dr. Szerlip says. "Anywhere from 50 to 70 percent of those patients die and over the past 20 years, despite dialysis, that has not changed much." He hopes the new device, developed by Dr. H. David Humes at the University of Michigan, can help...

New binding target for oncogenic viral protein

...zed. "The study of DNA tumors viruses has been an extremely important tool in understanding the cellular pathways that regulate cell division and are disrupted in cancer. Understanding the mechanisms through which these viruses interact with the cellular machinery that regulates cell division may lead to new ...

Study Demonstrates Gene Expression Microarrays are Comparable and Reproducible

...nd compared.Sample correlation within each lab was extremely high; microarray datafrom the RNA samples had the highest correlation values, followed bythe cell lines, and then finally the tissue samples. This was notsurprising, as RNA required the fewest steps of preparation, whiletissues required the most. The...

The transparent organism: EMBLEM and Carl Zeiss give labs a unique look at life

... a flood of requests for the instrument. "We were extremely pleased to have found Carl Zeiss as an excellent partner to translate this technology into a product," says Dr. Martin Raditsch, Deputy Managing Director of EMBLEM. EMBL Director-General Prof. Fotis Kafatos and EMBL Group Leader Dr. Ernst Stelzer me...

Color-blind method opens new doors in DNA sequencing

...nd the number of mistakes that can be tolerated is extremely low," said Curl, University Professor, the Kenneth S. Pitzer-Schlumberger Professor of Natural Sciences and professor of chemistry. "Our new method does away with identification problems altogether, because the imaging is very clean." Metzker said, ...

Vital step in cellular migration described by UCSD medical researchers

... to birth and beyond, cell migration is a complex, extremely important process that is not completely understood by researchers. In order to move, a cell must be polarized so that the molecular processes at the front end and back end are different, leading only to forward movement. One of the first steps in ce...
