Higher daily doses of rifampin, a cornerstone of tuberculosis treatment, killed more TB bacteria in sputum cultures, and the higher doses did so without increasing the adverse effects of treatment, according to a randomized controlled trial published online in the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine. In “Efficacy and Safety of High-Dose Rifampin in Pulmonary […]

University of Queensland researchers have discovered how to reverse drug resistance in skin and mouth squamous cell carcinomas. UQ Diamantina Institute Associate Professor Nicholas Saunders said squamous cell carcinomas was curable when diagnosed early but difficult to eradicate once the cancer spread. “This cancer of the skin and mouth kills approximately 1,400 Australians each year,” Dr. Saunders said. “The drugs […]

A potentially new way of treating cerebral malaria has been discovered by scientists at the Universities of Manchester and Glasgow, in a study using mice. The authors found that inhibiting a complex called the inflammasome, at the same time as delivering anti-malarial drugs, reduced mortality from experimental cerebral malaria in mice. The research, published in PNAS and funded by the […]

Monash University researchers have restored movement and regenerated nerves using stem cells in zebra fish where the spinal cord is severely damaged. The research, presented at the International Society for Stem Cell Research conference in Melbourne this week, raises the possibility that these same stem cells could be triggered in human patients who have suffered paralysing damage to their nervous […]
