Researchers at the University of Pittsburgh have constructed a novel delivery system for gene therapy of liver disorders, using a reconstituted chylomicron remnant (RCR) that can safely transport genes to target cells. The system has resulted in extended production of therapeutic proteins in animal models.
Computer scientists at Washington University in St. Louis have developed processes that enable internet address lookup to be done at a speed of 100 nanoseconds, compared to the current average of 1.2 microseconds. This promises to give routers faster throughput by making it easier to find destination addresses for messages.
A new program using free phone counseling has shown to improve social contact and reduce symptoms of depression in seniors identified as suicide risks. After four months, clients reported significant improvements in daily living challenges and life situations.
A long-term study found that post-menopausal women who used estrogen replacement therapy performed better on visual memory tests than those who didn't receive treatment. The researchers also found that stable memory performance was maintained by some participants who began ERT during regular visits to the NIA.
University of Wisconsin-Madison experts conduct detailed surveillance on H5 influenza, a deadly strain found in birds that has infected eight people and killed three. The study aims to identify the source of the virus, test for genetic variation between bird and human strains, and determine potential public health risks.
Research by Joanne Schneider found that women who interpret their exercise experience positively tend to exercise more often, intensely, and for longer periods. In contrast, those who focus on bodily movements report exercising less often, less intensely, or for shorter periods.
Researchers found that oral administration of a steroid hormone boosts circulating leptin levels in humans, with higher levels observed in obese individuals. The study suggests that overweight people still have leptin reserves and may benefit from high-dose leptin therapy.
