OHSU-VAMC study sheds light on estrogen's benefit for MS
... frequently in females than in males. But the link between
pregnancy and MS has been hotly debated. In 1998, scientists in France went a step closer to putting the issue to rest when they conducted the first large study aimed at assessing pregnancy and delivery on the course of the disease. The group found t...

281 and 317 individuals still exist in 19 distinct populations. Rampant development separates the remaining populations of this langur species, preventing the groups from interacting with one another. Fourteen of the groups are likely to disappear wi...

the summer and winter monsoons - the monsoon transition periods. Nitrogen oxide (NOx = NO + NO2) is an important component of tropospheric chemistry, which catalyzes ozone production and influences hydroxyl radicals, the "detergent" of the atmosphere...
