Consequently, several cell death mechanisms （secondary lesion mechanisms） such as necrosis, excitotoxicity, free radical production and inflammation are triggered （Castillo, 2000）.展开更多

During surgery a tumor located in the small bowel that caused intestinal occlusion was found. Histopathologic anal ysis showed a solitary gastrointestinal myofibroma. This is a very rare tumor, e specially as a single lesion, because in world literature, there are less than 1 0 cases reported.展开更多

He has many friends in my country since some of the investigations that led to the development of the LHRH agonists were made in a couple of Mexican hospitals in collaboration with some outstanding Mexican physicians that I will mention later. In that time, I was the head of the Department of Urology of the Mexican National Cancer Institute and our Director, Dr. Jaime de la Garza, invited him for a meeting. I was surprised by his humbleness, intelligence and easy going personality, in spite of being a Nobel Prize scientist.展开更多
