Morphologic changes in efferent ductules and epididymis in estrogen receptor-alpha knockout mice
Morphologic changes efferent ductules epididymis estrogen receptor-alpha
2008/12/25
Estrogen has been shown to have an important role in fluid reabsorption in efferent ductules of the testis. Our previous study of the estrogen receptor-alpha knockout mouse (ERKO) showed that the ...
Serotonin Concentration, Synthesis, Cell Origin, and Targets in the Rat Caput Epididymis During Sexual Maturation and Variations Associated With Adult Mating Status：Morphological and Biochemical Studies
5-hydroxytryptamine tryptophan hydroxylase neuroendocrine cells male reproduction serotonin receptor spermatozoa
2008/12/24
The caput epididymis of some mammals contains large quantities of serotonin whose origin, targets, and physiological variations have been poorly studied. We combined morphological and biochemical...
Mechanisms of cell communication are of paramount importance in multicellular organisms, because they are responsible for the coordination of basic processes, such as growth, differentiation, immu...
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 t...
Age-Related Epididymis-Like Intratesticular Structures：Benign Lesions of Wolffian Origin That Can Be Misdiagnosed as Testicular Tumors
Testis rete testis cysts aging
2008/12/23
This study aims to characterize the epididymis-like intratesticular structures (ELITSs), a rare lesion found in elderly men. ELITSs were identified in 6 patients from a review of 1442 autopsies an...
Epithelial Localization of Green Fluorescent Protein-Positive Cells in Epididymis of the GAD67-GFP Knock-in Mouse
Narrow cell GABA immunohistochemistry GABAA receptor GABAB receptor
2008/12/23
-Aminobutyric acid (GABA), which is a major inhibitory neurotransmitter in the brain, is also found in many peripheral nonneuronal tissues, including male reproductive organs. However, the distrib...
Identification and Characterization of an Antigen Recognized by Monoclonal Antibody TRA 54 in Mouse Epididymis and Vas Deferens
Testis sperm antigens cryptorchidism castration testosterone replacement
2008/12/22
Spermatozoa in testicular fluid are known to have weak forward motility and cannot fertilize eggs. The epididymis is known to participate in sperm maturation leading fertilization, but little is k...

Calcification of the Epididymis and the Tunica Albuginea of the Corpora Cavernosa in Patients on Maintenance Hemodialysis
Peyronie disease chronic renal failure hemodialysis ultrasonography epididymis end-stage renal disease
2008/12/22
The aims of this study were to determine the incidence rates of genital calcification in male hemodialysis patients based on ultrasonography findings and to identify risk factors for this conditio...
Expression of the p63 and Notch Signaling Systems in Rat Testes During Postnatal Development：Comparison With Their Expression Levels in the Epididymis and Vas Deferens
Spermatogenesis p53 differentiation
2008/12/22
The role of tubular structures that contribute to the passage of spermatozoa is not solely passive; these structures actively contribute to their own functions, although these tubules and ducts ar...
Sonic Hedgehog Pathway Genes Are Expressed and Transcribed in the Adult Mouse Epididymis
Gene transcription efferent duct ligation
2008/12/22
One role of the hedgehog (hh) signaling pathway during development is to assist in establishing pattern orientation in the embryo. The structure and function in the adult epididymis is highly patter...
Cell Specificity of Aquaporins 0, 3, and 10 Expressed in the Testis, Efferent Ducts, and Epididymis of Adult Rats
Water transport Sertoli basal nonciliated androgens
2008/12/22
Aquaporins (AQPs) are transmembrane protein channels that allow the rapid passage of water across an epithelium at a low energy requirement, though some also transport glycerol, urea, and solutes ...
