New discovery in living cell signaling

New discovery in living cell signaling

A breakthrough discovery into how living cells process and respond to chemical information could help advance the development of treatments for a large number of cancers and other cellular disorders that have been resistant to therapy. An international collaboration of researchers, led by scientists with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley, have unlocked the secret behind the activation of the Ras family of proteins, one of the most important components of cellular signaling networks in biology and major drivers of cancers that are among the most difficult to treat Continue reading

Teen mental health: Teenagers go from school psychologist to family doctor

Teen mental health: Teenagers go from school psychologist to family doctor

After initially visiting a school psychologist, adolescents in the United States with a mental disorder often go to seek care from their pediatricians or family doctors. Fewer of them continue their treatment directly with a psychotherapist or doctor specialized in mental disorders. This shows an analysis conducted by scientists at the University of Basel that has just been published in the academic journal PLOS ONE Continue reading

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.

Magnetic levitation tissues could speed toxicity tests

Magnetic levitation tissues could speed toxicity tests

Jan. 24, 2013 — In a development that could lead to faster and more effective toxicity tests for airborne chemicals, scientists from Rice University and the Rice spinoff company Nano3D Biosciences have used magnetic levitation to grow some of the most realistic lung tissue ever produced in a laboratory.

Cholesterol drug shows promise in fighting effects of malaria

Cholesterol drug shows promise in fighting effects of malaria

Dec. 27, 2012 — Researchers have discovered that adding lovastatin, a widely used cholesterol-lowering drug, to traditional antimalarial treatment decreases neuroinflammation and protects against cognitive impairment in a mouse model of cerebral malaria. Continue reading

NASA light technology successfully reduces cancer patients painful side effects from radiation and chemotherapy

NASA light technology successfully reduces cancer patients painful side effects from radiation and chemotherapy

ScienceDaily (Mar. 6, 2011) — A NASA technology originally developed for plant growth experiments on space shuttle missions has successfully reduced the painful side effects resulting from chemotherapy and radiation treatment in bone marrow and stem cell transplant patients. In a two-year clinical trial, cancer patients undergoing bone marrow or stem cell transplants were given a far red/near infrared Light Emitting Diode treatment called High Emissivity Aluminiferous Luminescent Substrate, or HEALS, to treat oral mucositis — a common and extremely painful side effect of chemotherapy and radiation treatment.

Most large treatment effects of medical interventions come from small studies, report finds

Most large treatment effects of medical interventions come from small studies, report finds

ScienceDaily (Oct. 23, 2012) — In an examination of the characteristics of studies that yield large treatment effects from medical interventions, these studies were more likely to be smaller in size, often with limited evidence, and when additional trials were performed, the effect sizes became typically much smaller, according to a study in the October 24/31 issue of JAMA . “Most effective interventions in health care confer modest, incremental benefits,” according to background information in the article.
