It is well known that transit through the epididymis involves an increase in the compaction of sperm chromatin, which acquires fully condensed status at the caput epididymidis. The purpose of this study was to compare the terminal deoxyribonucleotidyl transferase-mediated dUTP nick end-labelling (TUNEL) assay, the comet assay, the sperm chromatin structure assay (SCSA) and the sperm chromatin d...

AIM To study the secretory activity and androgen regulation of glutathione peroxidase (GPx) in epithelial cell cultures from human epididymis. METHODS Tissue was obtained from patients undergoing therapeutic orchidectomy for prostatic cancer. Epithelial cell cultures were obtained from the caput, corpus and cauda epididymides. Enzymatic activity was measured in conditioned media by colorimetr...

Biceps brachii is stated as one of the muscles that shows most frequent anatomical variations. Its most commonly reported anomaly is the presence of a third head arising from the humerus which is termed as Caput Accessorium ,therefore, detailed knowledge of this variation in different populations is important for surgical interventions of the arm, nerve compression syndromes and in unexplained ...

prizes for doctors working on immunity were those received in 1960 by Sir Macfarlane Burnet (35) and Sir Peter Medawar for their work in acquired immunological tolerance to tissue transplants. The 1913 medicine prize was awarded to Charles Robert Richet, 1850-1935, the French physiologist, for his work on serology and serum treatment. Together with the French bacteriologist Paul Jones Portier, ...
