Does bruch 's membrane aging decrease phagocytosis of outer segments by retinal pigment epithelium?
Aging of human Bruch's membrane decreases rod outer segment phagocytosis by ARPE-19. This effect can be mimicked by nonenzymatic nitration of extracellular matrix in vitro. Our observations may have implications for understanding the role of aging changes within Bruch's membrane on pathogenesis of age-related macular degeneration and other disorders.
Neither ketorolac nor bupivacaine decreased the postoperative narcotic requirement in patients undergoing microsurgical lumbar discectomy. Postoperative narcotic requirements are increased in patients who are in severe pain before surgery, regardless of preoperative narcotic use.
