(1) In spite of the fact that veinlet and cubitus interruptus affect closely related developmental processes, the ci isoalleles had no effect upon the expression of veinlet.
(2) Polygenic modifiers affecting the expression of the mutant veinlet were studied to determine whether each acts specifically upon one vein or wing region or whether they affect the venation pattern in some general way.
(3) In order to test the assumption that isoalleles can contribute to polygenic variation, several isoalleles of cubitus interruptus were examined for their influence upon the quantitative expression of a related venation mutant, veinlet.
(4) The hydraulic conditions are described, and attention is drawn to the microvasculartissue consequences of the stasis, the degree of constraint exercised by the interstitial tissue, and the role played by the intricate "micro fiber" network of the microcirculation: only a part of the capillaries reconnect with the veinlet of the same circulatory unit, the others having to flow toward the veinlet of other units and only one initial lymphatic vein contributing to the evacuation of 3 to 4 veinlets.
(5) These results support the hypothesis that the polygenic modifiers affecting veinlet expression function independently of the veinlet locus, presumably by influencing common steps in the developmental processes leading to the formation of individual veins.
(6) The calf's reticulum, network of veinlets reinforced with arches, is a group of intersaphenous anastomosis.

Example Sentences:
(1) Before the procedure the portal vein was found to be communicated with cardial and esophageal veins by two pathways, i,e., from the esophageal and gastric branches of the coronary vein to the esophageal varices, with the latter branches by way of the gastric intramural venula.
(2) Two groups of vascular structures were investigated: avascular part represented by pseudovessels and vascular part with protocapillaries, capillaries, sinusoids and venulae that are distinguished by their morphofunctional properties and the degree of maturity.
(3) In the dog with selective infusion of India ink into retroarticular veins, however, wide range of the distribution of the pigment in subarchnoidal venulae was observed.
(4) The necrosis results from the massive obliteration of the cutaneous venulae, not from the arterial failure.
(5) The light and electromicroscopical studies (cases 1 and 2) of a N. Suralis (neuropathic cases) display a loss of large myelinated fibers and marked reduced unmyelinated axons associated with osmiophilic inclusions in Schwann cells and endothelial venulae.
(6) If early biopsies show intravascular presence of macrophages in venulae or capillaries usually combined with a C3-deposition in glomular capillary walls, the prognosis of graft outcome seems to be poor even with rather heavy antirejection therapy.
(7) Arteriolae rectae coursed around interlobar veins before returning to the corticomedullary area, as venulae rectae.
(8) The light and electron-microscopical study of sural nerve displayed a loss of large myelinated fibers and a marked reduction of unmyelinated axons, associated with osmiophilic lamellated inclusions in Schwann cells and endothelial venulae.
(9) The main pathophysiological status, causing the pulmonary lesions, seemed to be peripheral circulatory insufficiency with increased permeability of peripheral vessels, especially of venulae.
(10) The results show that all the four tested filling materials (Biogloss, Evicrol, Isomolar, Isopast) significantly widened the pulpal arteriola; the Biogloss was ineffective for the diameter of the venula, but employing Evicrol, Isomolar and Isopast it was significantly increased.
(11) from the esophageal branches of the coronary vein to the esophageal varices, and from the gastric branches of the coronary vein to the esophageal varices by way of the gastric intramural venula.
(12) Data suggest that primary injured microvessels in SSc are likely to be arteriolae while venulae could be affected by secondary hypoxia due to the arteriolar damage with consequent release of tissue type plasminogen activator.
(13) Biopsy of the skin revealed involvement of the dermovascular loops with localized necrosis from extensive occlusion of dermal capillaries and venulae by fibrin thrombi.
(14) In an experimental study on rats and sheep we demonstrated by means of light reflexion rheography and laser doppler fluxmetry that manual lymphatic drainage therapy causes vessel narrowing followed by increased blood flow in the arterioles, capillaries and venulae of the skin as well as in peripheral arteries and an increased lymph flow in lymphatic collectors.
(15) There was a scattered involvement of capillaries and venulae in leptomeninges, peripancreatic and perirenal adipose tissue, pericardium, myocardium.
(16) We conclude that the local administration of RLX influences the microcirculation, possibly through an action on the smooth muscle of the venulae.
(17) Intravenous injection of carbon particles revealed an increased permeability of the venulae from the submucosa and serosa.
