Choice of Female-Controlled Barrier Methods Among Young Women and Their Male Sexual Partners
Female-Controlled Barrier Young Women Male Sexual Partners
2009/9/16
Little is known about the factors associated with the choice of female-controlled, over-the-counter barrier contraceptive methods among women and their male sexual partners.
Methods: Predictors of...
Ultrastructural studies on the development of the blood-epididymis barrier in immature rats
Ultrastructural studies blood-epididymis barrier immature rats
2009/2/23
The development of the blood-epididymis barrier in immature rats (8, 11, 14, 18, and 21 days old) was examined with an electron microscope using lanthanum nitrate as an electron dense tracer. A grad...
The effects of aging on the seminiferous epithelium and the blood-testis barrier of the Brown Norway rat
seminiferous epithelium blood-testis barrier Brown Norway rat
2009/2/18
Steroidogenesis and spermatogenesis decrease in aging Brown Norway rats. We therefore hypothesized that there must be accompanying morphological changes taking place in the seminiferous tubules of...
The distribution of connexin 43 is associated with the germ cell differentiation and with the modulation of the Sertoli cell junctional barrier in continual（guinea pig）and seasonal breeders'（mink）testes
Gap junction Cx43 Sertoli cell blood-testis barrier
2009/2/13
To test whether the gap junction protein connexin 43 (Cx43) is associated with germ cell differentiation and with the Sertoli cell junctional blood barrier, we recorded the temporal changes in its d...
Long-term alterations in the permeability of the blood-testis barrier following a single intratesticular injection of dilute aqueous glycerol
Blood-testis barrier permeability glycerol seminiferous tubules Sertoli cells
2009/2/12
The mechanism whereby glycerol exerts its antispermatogenic action is not known. The objective of this study was to determine, with the use of [3H]inulin and [125I]albumin by in vivo and in vitro ...
Pituitary adenylate cyclase activating polypeptide（PACAP）can cross the vascular component of the blood-testis barrier in the mouse
Influx constants transport peptide T vasoactive intestinal polypeptide
2009/2/12
Pituitary adenylate cyclase activating polypeptide (PACAP), present in highest concentrations in the hypothalamus and testes, affects the release of LH, FSH, and prolactin, as well as Sertoli cell...
The inter-Sertoli tight junction permeability barrier is regulated by the interplay of protein phosphatases and kinases：an in vitro study
Testis Sertoli cells protein tyrosine phosphatase protein
2008/12/29
The timely opening and closing of inter-Sertoli cell tight junctions in the rat testis are essential cellular events in the completion of spermatogenesis. They permit the passage of preleptotene and...
Neonatally administered diethylstilbestrol retards the development of the blood-testis barrier in the rat
diethylstilbestrol blood-testis rat
2008/12/26
Newborn rats were treated with 10 microg of diethylstilbestrol (DES) on alternate days from the 2nd to the 12th postnatal day, and the testes were sequentially examined up to 105 days of age by light,...
The effect of cardiac arrest on the blood-testis barrier to albumin, tumor necrosis factor-alpha, pituitary adenylate cyclase activating polypeptide, sucrose, and verapamil in the mouse
blood-testis albumin tumor necrosis factor-alpha pituitary adenylate cyclase
2008/12/26
Impotence commonly occurs after events such as acute myocardial infarction, coronary bypass, head trauma, and cerebral bleeding, including subarachnoid hemorrhage. We hypothesize that the hypoxia ac...
