Political strife undermines HIV treatment

Among other tragedies in countries with HIV epidemics, political violence can have the additional long-term consequence of an increase in viral resistance to treatment and HIV treatment failure, say the authors of a new paper in AIDS Reviews. The researchers, who have studied post-strife treatment failure and resistance in Kenya, argue that officials and health care providers need to study and prepare for how violence disrupts antiretroviral treatment and complicates the epidemic.

Better diagnosis and treatment of cancer could hinge on the ability to better understand a single cell at its molecular level. New research offers a more comprehensive way of analyzing one cell’s unique behavior, using an array of colors to show patterns that could indicate why a cell will or won’t become cancerous.

A University of Washington team has developed a new method for color-coding cells that allows them to illuminate 100 biomarkers, a ten-time increase from the current research standard, to help analyze individual cells from cultures or tissue biopsies. The work is published this week (March 19) in Nature Communications. (more…)

Grandfather, 57, looks forward to celebrating Easter with family and friends

Fernando Padilla could barely breathe or walk more than a few steps. An incurable disease, pulmonary fibrosis, was causing his lungs to turn to hardened scar tissue, and he was permanently tethered to an oxygen tank. His only hope was a double lung transplant.

Clean Syringes Often Unavailable in St. Petersburg, YSPH Research Finds

Russia’s HIV epidemic is among the fastest growing in the world and injection drug users who often share needles and other supplies are hardest hit. This occurs even though pharmacies are a legal source for clean syringes and can sell them without restriction.

A recent study led by the Yale School of Public Health and St. Petersburg State University mapped the city’s 965 pharmacies and compared their locations and density to HIV prevalence at the district level. (more…)

This year’s unusually long and rocky flu season would be nothing compared to the pandemic that could occur if bird flu became highly contagious among humans, which is why UCLA researchers and their colleagues are creating new ways to predict where an outbreak could emerge.

“Using surveillance of influenza cases in humans and birds, we’ve come up with a technique to predict sites where these viruses could mix and generate a future pandemic,” said lead author Trevon Fuller, a UCLA postdoctoral research fellow at the Institute of the Environment and Sustainability’s Center for Tropical Research.

Beetroot juice – the winning formula for team sports

New research shows that drinking beetroot juice can significantly improve performance in team sports involving bouts of high intensity exercise.

Trials by the University of Exeter Sport and Health Sciences department have found a direct link between the high nitrate content of beetroot and the chemical processes needed to get muscles working at their most efficient during intermittent bursts of activity.

During the tests, sportsmen were either given beetroot juice with a full complement of nitrates, or juice which had had the nitrate removed. Those who had taken the nitrate-rich juice were found to have a distinct advantage when exercising over those who had been given the control juice to drink. (more…)
