RUB-Researchers from the Chair for Biophysics have developed a new method for the detailed study of the interaction between pharmaceuticals and their target proteins. . The pharmaceutical industry has already taken notice of the new infrared spectroscopy technique. "We want to undertake a targeted screening of substance libraries to look for potential pharmacological agents," Prof. Dr. Klaus Gerwert said.

Researchers have identified a new stem cell population in the skin epidermis responsible for tissue repair. The skin, which is an essential barrier that protects our body against the external environment, undergoes constant turnover throughout life to replace dead cells that are constantly sloughed off from the skin surface. During adult life, the number of cells produced must exactly compensate the number of cells lost. Different theories have been proposed to explain how this delicate balance is achieved. In a new study, researchers demonstrate the existence of a new population of stem cells that give rise to progenitor cells that ensure the daily maintenance of the epidermis and demonstrate the major contribution of epidermal stem cells during wound healing.

The highest levels ever of DDT in breast milk have been measured in mothers living in malaria-stricken villages in South Africa. The values lie well over the limits set by the World Health Organization. DDT has been used for many years in South Africa, sprayed indoors to fight malaria.

The respective size of the pulmonary artery compared to the aorta, visible on a CT scan, is a strong predictor of the risk of exacerbation of chronic obstructive pulmonary disease, according to new research from UAB. The research team says that an increase in the size of the pulmonary artery relative to the size of the aorta is a valid indicator that a patient with COPD is at risk for exacerbating their disease. These exacerbations of COPD are associated with accelerated loss of lung function, worsened quality of life and increased risk of death.

Hospitals can dramatically reduce the number of life-threatening central line infections in pediatric cancer patients by following a set of basic precautions, by encouraging families to speak up when they observe noncompliance with the protocol and by honest analysis of the root cause behind every single infection, according to a new study.

(Phys.org)—Tuberculosis or TB as it's become more commonly known, is a horrible disease by all accounts, it slowly kills many of its victims, particularly those living in the developing world. In 2010, it killed an estimated four thousand people every single day, which is particularly horrendous when noting that many of those who succumb to its effects could be have been saved were they to be diagnosed and treated in a timely manner. Unfortunately, in many areas of the world neither is available, thus the news that a team of researchers working together from several universities in the US has developed a new kind of test that reveals the presence of TB in patients, both quickly and cheaply, is truly exciting. The new probe, as the team describes in their paper published in Nature Chemistry, can allow for TB detection using nothing more than a simple box housing light emitting diodes and some filters.
