Multitarget TB drug could treat other diseases, evade resistance

Multitarget TB drug could treat other diseases, evade resistance

A drug under clinical trials to treat tuberculosis could be the basis for a class of broad-spectrum drugs that act against various bacteria, fungal infections and parasites, yet evade resistance, according to a study by University of Illinois chemists and collaborators. Led by U. Continue reading

More effective kidney stone treatment, from macroscopic to nanoscale

More effective kidney stone treatment, from macroscopic to nanoscale

Researchers in France have hit on a novel method to help kidney stone sufferers ensure they receive the correct and most effective treatment possible. Kidney stones represent a major medical problem in the western and developing world. If left untreated, apart from being particularly painful, they can lead to renal failure and other complications.

Potent, puzzling and (now less) toxic: Team discovers how antifungal drug works

Potent, puzzling and (now less) toxic: Team discovers how antifungal drug works

Scientists have solved a decades-old medical mystery — and in the process have found a potentially less toxic way to fight invasive fungal infections, which kill about 1.5 million people a year. The researchers say they now understand the mechanism of action of amphotericin, an antifungal drug that has been in use for more than 50 years — even though it is nearly as toxic to human cells as it is to the microbes it attacks.

Most breast cancers are treated by blocking their addictions, for example depriving estrogen-fueled tumors of estrogen. But what about breast cancers without these hormonal addictions Continue reading

Blocking DNA repair mechanisms could improve radiation therapy for deadly brain cancer

Blocking DNA repair mechanisms could improve radiation therapy for deadly brain cancer

UT Southwestern Medical Center researchers have demonstrated in both cancer cell lines and in mice that blocking critical DNA repair mechanisms could improve the effectiveness of radiation therapy for highly fatal brain tumors called glioblastomas. Radiation therapy causes double-strand breaks in DNA that must be repaired for tumors to keep growing Continue reading

Rilpivirine combination product in pretreated HIV-1 patients: Added benefit not proven

Rilpivirine combination product in pretreated HIV-1 patients: Added benefit not proven

The German Institute for Quality and Efficiency in Health Care (IQWiG) reassessed the antiviral drug combination rilpivirine/emtricitabine/tenofovir. Continue reading

Rilpivirine combination product in pretreated HIV-1 patients: Added benefit not proven

The German Institute for Quality and Efficiency in Health Care (IQWiG) reassessed the antiviral drug combination rilpivirine/emtricitabine/tenofovir. In early 2012, the combination was approved for the treatment of adults infected with human immunodeficiency virus type 1 (HIV-1) who have not received previous antiretroviral treatment.

Patient stem cells help identify common problem in ALS

Patient stem cells help identify common problem in ALS

Harvard stem cell scientists have discovered that a recently approved medication for epilepsy may possibly be a meaningful treatment for amyotrophic lateral sclerosis (ALS) — Lou Gehrig’s disease, a uniformly fatal neurodegenerative disorder. The researchers are now collaborating with Massachusetts General Hospital to design an initial clinical trial testing the safety of the treatment in ALS patients. The investigators all caution that a great deal needs to be done to assure the safety and efficacy of the treatment in ALS patients, before physicians should start offering it Continue reading
