Phosphatidylcholine synthesis in human spermatozoa     Phosphatidylcholine synthesis  human spermatozoa       font style='font-size:12px;'> 2009/2/23
To clarify the mechanism of phospholipid synthesis in spermatozoa, fresh human spermatozoa were incubated with labeled fatty acids and 1-acyl-lysophosphatidyl choline (LPC) in the presence or abse...
Four experiments were designed to investigate the influence of photoperiod and other environmental factors on androgen production and reproductive maturation in deer mice. Male prairie deer mice (Pe...
Effects of indomethacin (1.25 mg/kg) and aspirin (20 mg/kg) on testosterone-induced (0.25 mg/rat), and of indomethacin on dihydrotestosterone-induced (0.25 mg/rat) mitotic activity of the seminal ...
The secretory activity of the middle segment of the mouse caput epididymidis was studied using 3H-fucose as a precursor to glycoprotein. Young adult male mice were injected with a concentrated sol...
A modified perfusion system was developed to maintain an unconvoluted tubule from the corpus epididymidis of the rabbit in organ culture. The epididymal explant is submerged in a continuous flow of ...
Principal cells show marked structural differences in the proximal, middle, and distal regions of the vas deferens, reflective of diverse functional activities. In the present study, we performed el...
The basement membrane plays an important role in maintaining the structural and functional integrity of tissues. Altered basement membrane structure has been associated with severe functional impair...
We have previously identified a 26-kDa epididymal hamster sperm glycoprotein (P26h) that is involved in gamete interaction. This protein is added to the acrosomal cap during epididymal transit of sp...
The synthesis of docosahexaenoyl coenzyme A (22:6-CoA) was studied in a long-chain fatty acid: CoASH ligase (AMP)-enriched fraction from human spermatozoa and was compared to palmitoyl CoA (16:0-CoA...
Previous investigators have suggested metabolic cooperation between Sertoli and peritubular cells. This study concerns Sertoli cell and peritubular myoid cell interactions in terms of synthesis of...
It was recently observed that treatment of patients with a high dosage of human interleukin (IL-2) resulted in suppression of plasma concentrations of testosterone. A murine model was developed to a...
Dibromoacetic acid (DBA) is a by-product of drinking water disinfection that alters spermatogenesis in adult male rats. To identify a mechanism by which DBA alters spermatogenesis, seminiferous tubu...
Mullerian inhibiting substance (MIS) is a gonadal hormone that causes regression of the Mullerian ducts during male sexual differentiation. Postnatally, MIS inhibits the proliferation and differen...
Many men who have undergone vasectomy later request vasovasostomy. Unfortunately, significant numbers of these men remain infertile despite the reestablishment of patent ducts. This report examine...
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...
