Scientists calculate radiation dose in bone from victim of Hiroshima bombing: In an article published in PLOS ONE, Brazilian researchers describe the first retrospective dosimetric study by electron spin resonance spectroscopy using human tissue from nuclear attack victims

The bombing of the Japanese cities Hiroshima and Nagasaki by the United States in 1945 was the first and only use of nuclear weapons against civilian targets. A series of studies began in its aftermath to measure the impact of the fallout, in terms of both the radiation dose to which the victims were exposed

CRISPR/Cas9 silences gene associated with high cholesterol: Technique allowed researchers to reduce blood cholesterol levels in adult mice for six months following a single treatment

Biomedical engineers at Duke University have used a CRISPR/Cas9 genetic engineering technique to turn off a gene that regulates cholesterol levels in adult mice, leading to reduced blood cholesterol levels and gene repression lasting for six months after a single treatment. This marks the first time researchers have delivered CRISPR/Cas9 repressors for targeted therapeutic gene

Get off the golf cart if you have knee osteoarthritis

From presidents to retirees, more than 17 million people over the age of 50 golf regularly. Knee osteoarthritis, which causes swelling, pain and difficulty moving the joint, is one of the leading causes of disability in this age group. It may seem intuitive that golfers with knee osteoarthritis should stay off their feet and ride

Zimbabwe legalises cannabis for medical, scientific use

Zimbabwe has legalised production of cannabis for medicinal or scientific use, according to new regulations seen by AFP Saturday. A statutory instrument entitled Production of Cannabis for Medicinal and Scientific Use Regulations, said prospective producers can apply to the health ministry for a licence to grow cannabis but under strict conditions. “An application shall be

Sickle cell trait not linked to stroke in African-Americans

(HealthDay)—For African-Americans, sickle cell trait (SCT) seems not to be associated with the incidence of ischemic stroke, according to a meta-analysis published online April 23 in JAMA Neurology. Hyacinth I. Hyacinth, M.D., Ph.D., M.P.H., from Emory Children’s Center in Atlanta, and colleagues conducted a meta-analysis to examine whether SCT is associated with increased risk of

First results announced for the AVIATOR 2 international multicenter registry

Results of the AVIATOR 2 international registry are being presented as late-breaking clinical science at the Society for Cardiovascular Angiography and Interventions (SCAI) 2018 Scientific Sessions. The AVIATOR 2 is a multicenter prospective observational study of patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) in 11 international sites. The use of a novel
