Women who consume higher amounts of caffeine may have a lower risk of developing tinnitus — a steady ringing in the ear — than women who consume less, ...
The protective gear needed to get Sierra Leone’s health clinics reopened, coupled with public education about the Ebola epidemic, are the greatest areas of need, according to a Harvard Fulbright Fellow and physician from Sierra Leone.
Though the threat to the U.S. population from the Ebola outbreak in West Africa is low, the need in epidemic countries is great, says Michael VanRooyen, director of the Harvard Humanitarian Initiative.
In pre-clinical studies conducted by the researchers, a one-time, local injection of the hydrogel-drug combo prevented graft rejection for more than 100 days. This compared with 35.5 days for recipients receiving only tacrolimus, and 11 days for recipients without treatment or only receiving hydrogel.
