Sex Chromosome Aneuploidy: Prospective Studies on Children

This two-volume publication contains the proceedings of a NATO Advanced Study Institute, held in April 1978. The material is organized in five sections. In the first section J. Bonner presents a historic review of chromatin research. The following section describes biophysical and chemical methods used in the study of isolated chromatin, such as electron microscopy, circular dichroism, X-ray di...

The effect of parental ABO blood group on fetal surveillance

Background Several factors may cause infertility and fetal loss. Blood groups antigens seem to be implied in the mechanisms of infertility and fetal loss. Maternal natural antibody can react against father’s blood group antigens on spermatozoa. The effects of parental blood group system on infertility and fetal surveillance perceived by its manifestation in prezygotic (caused infertility) and ...

Children with Sex Chromosome Aneuploidy: Follow-Up Studies

The third chapter reviews the pharmacologic properties of antiplatelet drugs and the antiplatelet effects of drugs used in general medical practice. The drugs discussed include aspirin, non-steroidal anti-inflammatory agents, sulfinpyrazone, prostaglandins PGE1 and PGI2, dipyridamole, and other pyridamole-pyrimidine compounds. Especially helpful is a section on the effects of anesthetics, major...

Patients with abnormal sperm parameters have an increased sex chromosome aneuploidy rate in peripheral leukocytes.

BACKGROUND Patients with oligoasthenoteratozoospermia (OAT) and normal karyotypes have an increased sperm aneuploidy rate. This may be due to an altered intratesticular environment that affects the chromosomal segregation mechanism(s). Alternatively, it may be due to a generalized meiotic and mitotic abnormality. In this case, patients with abnormal spermatogenesis should also have an increased...
