(12) Probably there is a continuity of this system throughout the entire vascular pole including (1) all granulated cells, (2) all lacis cells, (3) the mesangium cells and (4) the adjacent smooth muscle cells of the vas afferens and vas efferens.
(13) Pain scores (VAS) and responses to a pain questionnaire were similar for both groups; however, within Group B improvement in mean VAS scores at rest with time were more sustained.
(14) Various techniques have been described, but in this surgeon's opinion the simplest and best method is to remove a length of a vas such that it becomes a physical impossibility to approximate the cut ends.

(17) Pretreatment of the vas deferens with both HNBTG and 2'-deoxycoformycin eliminated the difference in inhibitory potency between adenosine and 2-chloroadenosine.
(18) We interpret these results to indicate that angiotensins stimulate PGE production by adrenergic nerves in the vas deferens and that released norepinephrine mediates a part of the PGE production in response to the angiotensins.
(19) The effects of the ATP affinity label periodate-oxidized ATP (ATP-2',3'-dialdehyde; P-ATP) on contractile responses of the guinea pig vas deferens to ATP was characterized and compared to the effects of the specific P2x-purinoceptor photoaffinity label antagonist, arylazido aminopropionyl ATP (ANAPP3).
(20) Knowledge of the mechanical properties of the vas deferens is important in order to understand the mechanical interaction between an intravasal device (IVD) and the vas deferens--a necessary step for successful long-term implantation.

Example Sentences:
(1) Histological examination of the aorta showed atherosclerosis together with characteristic perivascular lymphocytic infiltration of the aortic vasa vasorum.
(2) 2 When the conversion of tyrosine was allowed to proceed as far as catecholamine (brocresine absent) no significant difference was observed between the accumulation of [14C]-catecholamines (CA) in depolarized rat vasa deferentia and the accumulation in control (non-depolarized) tissues.
(3) An identical type of lesions was revealed: disorders of the connective tissue, destruction of elastic fibers, alterations of vasa vasorum, with cellular reactions typical of each nosological form reflecting the peculiarities of the immunological processes.
(4) Distinct foci of lysis were present in the media and adventitia of all vein samples corresponding to the distribution of the vasa vasorum.
(5) Treatment of intact vasa deferentia with increasing concentrations of BAAM resulted in a progressive rightward shift in the dose-response curve to isoprenaline or salbutamol followed by a decreased maximum response.
(6) An antepartum diagnosis of vasa previa was considered in a patient in whom ultrasound revealed pulsatile loops of cord overlying the cervical os.
(7) In both rodents, when on a low protein-high water intake diet, considerable interstitial substance was found between the vasa recta of the bundles.
(8) Thus, vasa vasorum were shown to elongate their intramural segments in response to the changes of microenvironment in which the medial cells are placed, meeting the demand by the cells for increased supply of oxygen and nutrients.
(9) In sections of rat kidney, angiotensin II receptors were detected in the glomerulus, vasa recta and ureter.
(10) As blood flows through the interconnecting capillary plexus and up ascending vasa recta, transcapillary oncotic and osmotic pressure differences combine to cause capillary uptake of fluid.
(11) Insufficient blood flow through vasa vasorum may contribute to medial necrosis of the aorta and to aortic atherosclerosis.
(12) The method has proved generally stable and efficient, and has given significant computational results for a variety of models: calculations on single solute models of the coupled vasa recta nephron counterflow system have shown that for large water and solute permeabilities of the exchanging membranes, behavior of the non-ideal system approaches that of the previously described ideal central core model.
