Anxiety disorders surprisingly common yet often untreated

...ty to be as prevalent as depression, and much more common than previously thought, in patients who were visiting a physician for a physical problem or illness. "Anxiety often manifests as a physical symptom like pain, fatigue, or inability to sleep, so it is not surprising that one out of five patients ...

Smell may outlast other senses

...ood pressure lowering medications were amongst the common drugs known to interfere with smell. Conditions such as Parkinson’s disease and Alzheimer’s disease were also associated with impairment in the sense of smell, she said. Dr Johnston said the ability to smell was an important factor in the enjoyme...

Analysis of rhesus monkey genome uncovers genetic differences with humans, chimps

...olution of rhesus, chimp, and the human from their common ancestors ," said Richard Gibbs, Ph.D., director of Baylor College of Medicine's Human Genome Sequencing Center in Houston and the project leader. One of the most useful features of the rhesus genome is that it is less closely related to the hum...

Robotic therapy helps restore hand use after stroke

...rs, HOWARD aids patients as they grasp and release common objects. The robotic device wraps around the hand and couples with a computer program that directs patients though a physical therapy program.

Antifungal drug kills TB bug

...deadly infectious diseases say drugs used to treat common fungal infections may provide the answer. Tuberculosis, or TB, is a highly contagious disease of the lungs that was thought to have been virtually eliminated by the 1960s, but is now resurgent and kills nearly two million people worldwide every year...

Liver regeneration may be simpler than previously thought

... researchers noticed that only a few proteins were common to both processes. Proteins called transcription factors, which affect DNA in the cell's nucleus, were highly involved in the development of embryos' livers but not in adult liver regeneration. Instead, proteins that help cells proliferate were activ...

New mechanism for nutrient uptake discovered

... the rapid shut-off. They think it might be a very common regulatory event called phosphorylation, where a phosphate molecule is introduced to another molecule, changing the latter, and preparing it for a chemical reaction. They have found a site for phosphorylation and are looking at this possibility furth...

Rapid, Low-Cost DNA Testing

...e, and it's very quick. The most widespread and common method of screening DNA is called gel electrophoresis. Each test takes 1 hour and can cost as much as $1.00. Setting up a lab for gel electrophoresis requires a capital expenditure of $5,000. By contrast, Professor Rothberg's technique only requires ...

Study shows hope for early diagnosis of Alzheimer's

Mailman School of Public Health researchers report blood DNA can be early predictor of liver cancer

...rly detection is critical. HCC is one of the most common and rapidly fatal human malignancies. Worldwide, the almost 500,000 new cases and nearly equivalent number of fatalities illustrates the lack of effective therapeutic alternatives for this disease.
