1.1.2. Cyclooxygenase-prostanoid cascade
Figure 1.1. Metabolism of arachidonic acid
Despite the diverse chemical structure of aspirin-like drugs, the antinociceptive effect of NSAIDs is mainly due totheir common property of inhibiting cyclooxygenases involved in the formation of prostanoids. Prostanoids areformed by most cells and act as autocrine and paracrine lipid mediators. They are n
1908 - The term "stem cell" was proposed for scientific use by the Russian histologist Alexander Maksimov (1874–1928) at congress of hematologic society in Berlin. It postulated existence of haematopoietic stem cells.
1998 - James Thomson and coworkers derive the first human embryonic stem cell line at the University of Wisconsin–Madison.
