Drug-resistant bacteria on poultry products differ by brand

...oroquinolones are some of the most important drugs used to treat a variety of infections, including those caused by Campylobacter. The widespread presence of this drug-resistant form of the bacteria makes the antibiotic less effective in human medicine. Especially vulnerable are the very young, the elderl...

Programmable cells: Engineer turns bacteria into living computers

...or humans to reach. Programmed cells also could be used to control the repair or construction of tissues within the body, possibly guiding stem cells to the locations where they are needed for the growth of new nerve or bone cells in a process Weiss called "programmed tissue engineering." Even the early ...

UCLA launches $20 million stem cell institute to investigate HIV, cancer and neurological disorders

...ished clinical trials infrastructure that could be used to test new therapeutics that may develop as a result of the stem cell studies, said Judith C. Gasson, cancer center director, stem cell institute co-director, and a professor of medicine and biological chemistry. "I see cancer and stem cells as tig...

Gene Signatures Predict Interferon Response For Multiple Sclerosis Patients

...immune regulation—at each time point. The authors used statistical analyses to search for gene expression profiles that were associated with patients' therapeutic outcomes. They looked for patterns in analyses of single genes, gene pairs, and gene triplets, and found their model's predictive accuracy inc...

Chemists identify immune system mechanism for methamphetamine binges

...ne antibodies can be made in a laboratory and then used as a clinical treatment for addiction. In theory, antibodies to the drug could be mass produced and administered at therapeutic levels that are high enough to clear the drug from the body, he says. "Methamphetamine has become the ‘crack' of the 21st...

People who used HAART had lower risks of Kaposi sarcoma and non-Hodgkin lymphoma compared with those who did not use HAART, although even with HAART these tumors occurred 20 times more frequently than they do in the general population without HIV/AIDS. HAART use was...
