A combination of two drugs can selectively block pain-sensing neurons in rats without impairing movement or other sensations such as touch, according to a new study by National Institutes of Health (NIH)-supported investigators. The finding suggests an improved way to treat pain from childbirth and surgical procedures. It may also lead to new treatments to help the millions of Americans who suffer from chronic pain.

During evolution, many of a species’ properties are shaped by ecological interactions. This is readily evident in mammalian teeth, whose many features closely reflect what each species eats. However, for a long time scientists have suspected that genetic and developmental interactions may also influence species-specific properties.
After a rigorous review process, the American Dental Association (ADA) Council on Scientific Affairs has awarded the ADA Seal of Acceptance to Wrigley sugarfree chewing gums Orbit, Extra, and Eclipse, because they are clinically shown to help prevent cavities, reduce plaque acid and strengthen teeth.
The rare immunodeficiency disorder known as Job’s syndrome is caused by a specific genetic mutation that both overstimulates and understimulates the human immune system, leading to harmful bacterial and fungal infections and the physical features characteristic of the syndrome, according to two independent groups of scientists, one from the National Institutes of Health (NIH) and the other from the Tokyo Medical and Dental University.
The presence of mercury in dental amalgams, or fillings, is relatively common knowledge; however, whether its presence affects the neurological system is a debate that has been ongoing for 150 years.
Athletes know that damage to a tendon can signal an end to their professional careers. But a consortium of scientists, led in part by University of Southern California (USC) School of Dentistry researcher Songtao Shi, has identified unique cells within the adult tendon that have stem-cell characteristics?including the ability to proliferate and self-renew.
In Medicine, paracetamol is used to soothe every kind of pain, from simple molar pain to pain produced by bone fractures. This medicine is one of the most used nowadays. However, research carried out at the Departamento de Enfermeria of the University of Granada showed that taking paracetamol slows down bone growth, as has been proved by ?in vitro? studies.
Sleep disorder and ear, nose and throat specialists at Thomas Jefferson University are examining an innovative procedure to treat obstructive sleep apnea syndrome.
University of Arkansas researchers have found a simple, inexpensive way to create a nanowire coating on the surface of biocompatible titanium that can be used to create more effective surfaces for hip replacement, dental reconstruction and vascular stenting.
