There have been many exciting advances in our understanding of mammalian sex determination and differentiation in the last decade. Using these advances to elucidate clinical conditions of abnormal sexual development, the authors bring together great expertise in molecular endocrinology, molecular genetics, and dysmorphology. The text begins with a discussion of normal gonadal and sexual development that presents enough embryology, biochemistry, and endocrinology to make the remaining chapters easy to assimilate. Then the authors discuss overarching clinical issues that are common to genetic...

The fifth Annual Pezcoller Symposium entitled, Apoptosis, was held in Trento, Italy, June 9-1I, 1993 and was focused on the specific phenomena leading to Programmed Cell Death (PCD) or Apoptosis, and the mechanisms involved. With presentations at the cutting edge of progress and stimulating discussions, this Symposium addressed the genetics and molecular mechanisms determining PCD and the role of this suicidal process in cancer and the immune system. The functions of pS3, c myc and bel 2 in affecting apoptosis in different cell types and the role of ions and intracellular pH changes and that...
