Study identifies predictors of HIV drug resistance in patients beginning triple therapy

A scientist at the Marine BiologicalLaboratory (MBL) has published the results of an EPA-funded clam embryostudy that supports her hypothesis that, when combined, the pollutantsbromoform, chloroform, and tetrachloroethylene--a chemical cocktailknown as BCE--can act synergistically to alter a key regulator in nervecell development. While scientists have previously studied the effectsof these...

Researchers make gains in understanding antibiotic resistance

Howard Hughes Medical Institute researchers chiseling away at the problem of antibiotic resistance now have a detailed explanation of how the drugs' main cellular target in bacteria evolves to become resistant to some of these medications. The findings are already leading to new experimental antibiotics that are being engineered to circumvent resistance, which is a major worldwide health problem....

MUHC scientists describe genetic resistance to rampant virus

MUHC researchers have defined genetic resistance to the widespread virus, cytomegalovirus (CMV)--a member of the viral group that causes some of the world's most prevalent diseases, such as herpes, chicken pox and mononucleosis. The groundbreaking research published in Nature Genetics last week, provides a roadmap for the development of human therapies for CMV, which could prolong the life of HIV...

New polysaccharide may help combat multidrug resistance in cancer

In a recent study published in the Journal of Biological Chemistry, scientists report that a molecule previously thought to play a purely structural and inert role in cells is actually involved in multidrug resistance in cancer. Using antagonists for this molecule, the researchers were able to sensitize drug resistant breast cancer cells to chemotherapeutic drug treatment. The research ap...

To Stop Evolution: New Way Of Fighting Antibiotic Resistance Demonstrated By Scripps Scientists

A team of scientists at The Scripps Research Institute and the University of Wisconsin have demonstrated a new way of fighting antibiotic resistance: by stopping evolution. In the June issue of the open-access journal PloS Biology, the team describes how a protein called LexA in the bacterium Escherichia coli promotes mutations and helps the pathogen evolve resistance to antibiotics. The...

New antibiotic already developing resistance

An anti biotic, just a year old, which was developed to fight resistant bacteria, is already becoming stale as the bacteria are showing signs of resistance. The drug linezolid is used to treat Enterococcus faecium (E. faecium) infections that are resistant to the old standby antibiotic vancomycin. The hope has been that the new drug would help tackle the growing problem of vancomycin-res...

Early puberty more resistance

A recent study has found that early puberty and late menopause have better chances of surviving a broken hip.Broken hips are a common symptom of osteoporosis, or brittle bone disease.// Most women who sustain a hip fracture survive, but sometimes death can occur as a result. Researchers in Norway sought to investigate the impact a woman's reproductive variables, such as age when her p...

Training with weights helps building resistance

According to researchers, many people have believed that training with free weights - dumb bells and bar bells is best kept for youthful people.// According to Bruce Craig, of the Human Performance Laboratory at Atlanta University, men and women well past retirement age have much to gain from resistance training. Weight work increases your mobility and improves reaction time - both of w...

Link between birth weight and Insulin Resistance

According to researchers in England, a baby's birth weight is connected to the mother's insulin resistance in late adulthood. The study also shows women with the lightest and heaviest offspring had the highest risk of developing diabetes.// More than 4,100 women ages between 62 and 75 years participated in the study. Researchers found, as birth weight increased every 2.2 lbs, women had...
