Paracetamol no better than placebo for lower back pain

Paracetamol is no better than placebo at speeding recovery from acute episodes of lower back pain or improving pain levels, function, sleep, or quality of life, according to the first large randomised trial to compare the effectiveness of paracetamol with placebo for low-back pain. The findings, published in The Lancet, question the universal endorsement of paracetamol as the first choice painkiller for low-back pain, say the authors.

Rosemary and oregano contain diabetes-fighting compounds

The popular culinary herbs oregano and rosemary are packed with healthful compounds, and now lab tests show they could work in much the same way as prescription anti-diabetic medication, scientists report. In their new study published in ACS' Journal of Agricultural and Food Chemistry, they found that how the herbs are grown makes a difference, and they also identified which compounds contribute the most to this promising trait.

Transparency lacking in clinical trials

A significant percentage of completed drug clinical trials, especially those funded by industry, are not disclosed to the public, years after being completed - a trend that "threatens the validity of the clinical research literature in the U.S.," according to a study led by a Boston University School of Public Health (BUSPH) researcher.

Researchers eliminate the HIV virus from cultured human cells for first time

The HIV-1 virus has proved to be tenacious, inserting its genome permanently into its victims' DNA, forcing patients to take a lifelong drug regimen to control the virus and prevent a fresh attack. Now, a team of Temple University School of Medicine researchers has designed a way to snip out the integrated HIV-1 genes for good.

Niacin too dangerous for routine cholesterol therapy

After 50 years of being a mainstay cholesterol therapy, niacin should no longer be prescribed for most patients due to potential increased risk of death, dangerous side effects and no benefit in reducing heart attacks and strokes, writes Northwestern Medicine® preventive cardiologist Donald Lloyd-Jones, M.D., in a New England Journal of Medicine editorial.

Taking B vitamins won't prevent Alzheimer's disease

Taking B vitamins doesn't slow mental decline as we age, nor is it likely to prevent Alzheimer's disease, conclude Oxford University researchers who have assembled all the best clinical trial data involving 22,000 people to offer a final answer on this debate. High levels in the blood of a compound called homocysteine have been found in people with Alzheimer's disease, and people with higher levels of homocysteine have been shown to be at increased risk of Alzheimer's disease.

Scientists find genetic recipe to turn stem cells to blood

The ability to reliably and safely make in the laboratory all of the different types of cells in human blood is one key step closer to reality. Writing in the journal Nature Communications, a group led by University of Wisconsin-Madison stem cell researcher Igor Slukvin reports the discovery of two genetic programs responsible for taking blank-slate stem cells and turning them into both red and the array of white cells that make up human blood.
