ReviewDe Graaf ’ s Thread : The Human Epididymis
The epididymis consists of a single, highly coiled and convoluted tubule that Antoine De Graaf, the famous 17th-century anatomist, likened to a thread thickening to a string. The uncoiled tubule is several meters long and sperm in transit through it become functionally mature under the under the influence of the tubule lumen’s microenvironment. The regulation of that microenvironment and the ma...

متن کاملDermoscopy of Pitted Keratolysis
Irritated hyperhidrotic soles with multiple small pits are pathognomonic for pitted keratolysis (PK). Here we show the dermatoscopic view of typical pits that can ensure the diagnosis. PK is a plantar infection caused by Gram-positive bacteria, particularly Corynebacterium. Increases in skin surface pH, hyperhidrosis, and prolonged occlusion allow these bacteria to proliferate. The diagnosis is...
متن کاملPolyol pathway in human epididymis and semen.
Two enzymes are involved in the polyol pathway: an aldose reductase that reduces glucose in sorbitol followed by its oxidation in fructose by sorbitol dehydrogenase. It has been previously shown that both enzymes are presented in the bovine epididymis, where they are associated with membranous vesicles called epididymosomes. Based on the distribution of these enzymes, it has been hypothesized t...
متن کاملRegion-specific gene expression profiling along the human epididymis.
During their transit through the epididymis, spermatozoa undergo many biochemical modifications necessary to acquire flagellar motility and fertilizing ability. These modifications, collectively called sperm maturation, are well orchestrated along the epididymis and depend on highly regionalized gene expression patterns. Based on clinical observations, the role of the epididymis in human sperm ...
