Mitochondrial genome undergoes random reorganisation during reprogramming

Induced pluripotent stem cells (iPS cells) are truly talented multi-taskers. They can reproduce almost all cell types and thus offer great hope in the fight against diseases like Alzheimer's and Parkinson's. However, it would appear that their use is not entirely without risk: during the reprogramming of body cells into iPS cells, disease-causing mutations can creep into the genetic material.

Study finds harmful haloacetic acids in the urine of pool workers, swimmers

The first scientific measurements in humans show that potentially harmful haloacetic acids (HAAs) appear in the urine of swimmers within 30 minutes after exposure to chlorinated water where HAAs form as a byproduct of that water disinfection method.

Cocaine-free topical anaesthetics can effectively treat pain caused by torn skin

While some pain killers need to be injected into the damaged tissue in order to work, topical anaesthetics only need to be spread on the surface. The earliest examples of "topical" anaesthetics contained cocaine, but now a new systematic review has shown that newer agents that don't contain cocaine can effectively treat pain caused by torn skin.

Promising drug for Duchenne muscular dystrophy

Duchenne muscular dystrophy is a severely debilitating and lethal condition that affects 1 in 3,000. Females and males are affected, though females are rarely affected and are more often carriers. It is caused due to a defective gene that normally codes for the protein dystrophin, which helps provide a protective membrane around muscle fibers. Without this skin, muscle fibers become damaged and eventually die.

High methodological quality studies of PET in malignant melanoma patients needed

The relevance of positron emission tomography (PET) alone or in combination with computed tomography (CT) in patients with malignant melanoma cannot be currently assessed due to a lack of meaningful studies. This is the result of a final report published by the German Institute for Quality and Efficiency in Health Care (IQWiG) on 20 July 2011.
