This study was conducted to underscore the spatial distribution of some biologically active proteins within the epididymal duct in the dromedary camel. Paraffin-embedded sections from different regions of epididymis were stained by conventional histological techniques and by immunohistochemistry. A battery of primary antibodies against six proteins (S100, alpha smooth muscle actin [α-SMA], conn...

During its passage through the epididymis, the gamete undergoes a process of "maturation" leading to the acquisition of its fertilizing ability. The epididymis displays regional variations in the morphology and metabolic properties of its epithelium which are relevant for the progressive development of mature sperm characteristics. The epididymis has spontaneous peristaltic contractions and rec...

mother Figure 1 and 2. Therefore, in the field of APS encounter point and spotty hemorrhages that long retains after the birth (unlike caput succedaneum). The APS reflects the nature of the insertion head, changes its location when asynclitism. APS is a reflection (imprint) of delivery, which can be used to objectively evaluate the insertion head. APS is clearly visible on the head of the dead ...

PURPOSE To present characteristic MR findings of developmental venous anomalies (DVAs) in terms of location of caput and draining veins, to correlate these findings with normal medullary venous anatomy, and to suggest an approach to the evaluation of DVAs by means of MR imaging. METHODS We reviewed the contrast-enhanced MR examinations of 61 patients with DVA, which were selected from 4624 co...

The effects of protein synthesis inhibition and disassembly of microtubules in the epididymal epithelia on proluminal movement of 3H-androgens were investigated by using in vivo microperifusion of 3H-testosterone and subsequent micropuncture to obtain peritubular and intraluminal fluids of caput epididymal tubules. Cycloheximide (100 micrograms/ml) was used as protein synthesis inhibitor. Nocod...

Clear cells express the vacuolar proton-pumping H(+)-ATPase (V-ATPase) and acidify the lumen of the epididymis, a process that is essential for male fertility. The renin-angiotensin-aldosterone system (RAAS) regulates fluid and electrolyte balance in the epididymis, and a previous study showed binding of aldosterone exclusively to epididymal clear cells (Hinton BT, Keefer DA. Steroid Biochem 23...

Nutrient allocation closely correlates plant functional traits and development to ecosystem supply services. Desert shrubs maintain the stability of desert ecosystems, whereas knowledge how they coordinate nutrients among organs is still limited when responding differing nitrogen (N) water regimes. Here we investigated allocation, composition, variability nine elements within Alhagi sparsifolia...

Methylmercury (MeHg) is a widespread environmental contaminant that causes reproductive dysfunction in men. Metallothioneins (MTs) are low-molecular-weight proteins that can bind heavy metals and protect the cell from metal toxicity. MT levels are increased by exposure to metals and physiological stressors. Although MTs have been identified in the testis and epididymis, little is known about th...
