Platelet-rich fibrin matrix doesn't improve healing after rotator cuff repair

For years, doctors have used platelet rich plasma (PRP) to promote healing in various surgeries, but a recent study demonstrates that a type of PRP did not improve healing after rotator cuff repair.

Study: Low levels of Klotho protein may serve as early warning sign of CKD

Low levels of the anti-aging hormone Klotho may serve as an early warning sign of the presence of kidney disease and its deadly cardiovascular complications, according to findings by UT Southwestern Medical Center researchers.

Scientists find working memory highly dependent on fast inhibitory cells

Usually, we associate rhythms with dance and music. But they also play an important role in the brain. When billions of neurons communicate with each other, certain rhythmic activity patterns arise. The proper metre in this interplay is provided by nerve cells that do not excite other cells, but inhibit their activity instead. One type of these inhibiting cells acts in a particularly fast and efficient way and is therefore thought to be crucial for memory formation and information processing in neuronal networks.

New method to help unravel structural mysteries of nature

The team of Professor Burkhard Luy from KIT and Junior Professor Stefan F. Kirsch from the TUM has now shown for the first time that certain NMR parameters, the so-called residual dipolar couplings, can make a significant contribution towards determining the constitution of chemical compounds when traditional methods fail.

Scientists establish biomarker strategy to diagnose variety of cancer types

A team of biologists, clinical oncologists, pathologists and information scientists has established a strategy for identifying biomarkers. If a particular pattern of these biomarkers can be detected in the blood, this indicates a cancerous disease. An interdisciplinary research breakthrough that opens many doors.

Scientists discover axons can send signals to cell body

Neurons are complicated, but the basic functional concept is that synapses transmit electrical signals to the dendrites and cell body, and axons carry signals away.

Researchers identify normal movement mechanisms of PrPC in brain

Researchers at the University of California, San Diego School of Medicine have identified the motors that move non-infectious prion proteins (PrPC) - found within many mammalian cells - up and down long, neuronal transport pathways.

Smoking, exercise influence Vitamin E's effect on pneumonia risk

Depending on the level of smoking and leisure time exercise, vitamin E supplementation may decrease or increase, or may have no effect, on the risk of pneumonia, according to a study published in Clinical Epidemiology.

Avenir team discovers how Neisseria meningitidis disseminates into bloodstream

Although, in the majority of cases, the localized presence of Neisseria meningitidis in the throat has no consequence, it can sometimes lead to meningitis or septicaemia. The seriousness of these two infections is driving researchers from around the world to improve their understanding of the mode of operation of this bacterium, which, once it leaves its favourite location becomes extremely dangerous.

Two studies investigate frontiers of islet cell transplantation for treating diabetes

Two studies published in the current issue of Cell Transplantation investigate frontiers of islet cell transplantation for treating diabetes. Researchers in Milan, Italy re-examine the role of bone marrow stem cells in diabetic therapy and islet cell regeneration and Canadian researchers offer improved strategies for optimizing pancreatic islet culture in vitro.
