The human bulbo-urethral glands. A transmission electron microscopy and scanning electron microscopy study
human bulbo-urethral glands transmission electron microscopy scanning electron microscopy study
2009/2/23
This paper investigates the ultrastructure of human bulbo-urethral glands using specimens obtained at surgery. The tubulo-alveolar endpieces of these glands are lined by typical mucous cells in diff...
Nanovid microscopy for assessing sperm membrane changes induced by in vitro capacitating and acrosomal reacting procedures
Spermatozoa colloidal gold videomicroscopy
2009/2/12
This study was to verify the usefulness of Nanovid microscopy techniques for evaluating induced modifications in bovine spermatozoal membranes. Frozen thawed bovine sperm were labeled with 20-nm c...
Detection of the mouse acrosome reaction by acid phosphatase Comparison with chlortetracycline and electron microscopy
mouse acid phosphatase chlortetracycline electron microscopy
2008/12/26
The sperm acrosome is a uniquely regulated secretory vesicle containing several hydrolase enzymes, including acid phosphatase (AP). The exocytotic event that releases these enzymes, the acrosome react...
