How plague-causing bacteria disarm host defense

...the UCSD School of Medicine. Identifying this new target is the first step to developing effective strategies for preventing disease, including means to fight antibiotic-resistant strains of Yersinia that could be used in biological warfare, according to Navarro. The genus Yersinia includes thr...

Adult stem cells from human cord umbilical cord blood successfully engineered to make insulin

...of stem cells are thought to be required to create new organs. Researchers might remove thousands of donor cells from an individual and grow them in the laboratory into billions of cells, Denner explained. Then, for a person with type 1 diabetes, researchers might engineer these cells to become islets of...

Treating HIV in war zones -- Public health emergencies need rapid advice from WHO

...he World Health Organization (WHO) has developed a new mechanism, described in this week's PLoS Medicine, for issuing urgent guidelines to health professionals in a public health emergency such as an infectious disease outbreak. The first rapidly issued guideline was developed by the WHO in order to ...

Researchers use MRI to predict recovery after spinal cord injury

...with SCI or spinal dysfunction. An estimated 7,800 new cases of SCI occur each year. Motor vehicle accidents account for 44 percent of these injuries in the U.S. An initial MRI examination is typically performed on patients with SCI to determine the degree of neurological damage, as well as a possib...

Avian influenza survivors' antibodies effective at neutralising H5N1 strain

...Biomedicine in Switzerland. The researchers used a new technique that allows them to rapidly reproduce human monoclonal antibodies starting from a small sample of blood. "We can't say for certain that a pandemic influenza virus will resemble the H5N1 strain that we have been studying or that the monoc...

Common treatment for methamphetamine overdose may damage brain cells

...an area of the brain known to regulate movement, a new study shows. The findings, derived from experiments with rats, indicate that only the combination of the medication, haloperidol, and methamphetamine causes the destructive effects, not either one alone. Senior author Bryan Yamamoto, PhD, and his te...

Gene expression patterns predict rapid decline in idiopathic pulmonary fibrosis patients
