LEE, J, S. Contraction of villi and fluid transport in dog jejunal mucosa in vitro. Am. J. Physiol. 221(2) : 488-495. 1971.-An intestinal mucosal membrane preparation permitting simultaneous determination of the fluid transport rate and a microscopic examination of villi was employed. The occurrence of sustained villus shortening was invariably associated with diminution or abolition of fluid t...

The presence of myofibroblasts arranged parallel to the longitudinal axes of anchoring villi of the placenta has previously been described. Furthermore, it has been suggested that intraplacental blood volume, and hence fetal-maternal oxygen-nutrient exchange, may in part be regulated through the longitudinal contraction of anchoring villi. We demonstrate here that anchoring villi have the abili...

the aim of this study was to investigate the effects of dietary garlic on the growth performance, intestinal mucosa morphology, and pulmonary hypertensive response in broiler chickens with pulmonary hypertension induced by 3, 5, 3′-l triiodothyronine. chicks were reared for 42 days and treated with triiodothyronine (1.5 mg/kg diet) and 0 (control), 0.2, 0.6 or 1% garlic powder. intestinal segme...

The role of the endogenous apelin system in pregnancy is not well understood. Apelin's actions in pregnancy are further complicated by the expression of multiple forms of the peptide. Using radioimmunoassay (RIA) alone, we established the expression of apelin content in the chorionic villi of preeclamptic (PRE) and normal pregnant women (NORM) at 36-38 wk of gestation. Total apelin content was ...

The small intestine of two rallid aquatic birds (Fulica atra Linnaeus, 1758 and Gallinula chloropus (Linnaeus, 1758) from Bahr Al-Najaf depression, southwest city, mid-Iraq), were infected with the nematode Amidostomum acutum Seurat, 1918 a prevalence 25% 50%, respectively, mean intensity 24.5 30, respectively. showed several gross pathological microscopic lesions in their due to infection this...

The ileocaecal junction mucosal surface morphology of 5 horses and 1 donkey was examined using scanning electron microscopy and light microscopy. Based on differences in surface morphology, the junction could be divided into 4 distinct regions. The distal extremity of the ileum was characterized by the presence of typical finger-like villi followed by a narrow zone displaying short, stubby vill...

The microvillous membrane (MVM) potential ( E m) of first trimester human placental villi was measured and compared with that in villi from term human placentas. The median E m in first trimester villi (-28 mV) was significantly more negative than that at term (-21 mV; P < 0.001). The median E m measured in villi from early ( weeks 6-11) first trimester (-32 mV) was significantly more negative ...

Despite many striking connections, the biological similarities between embryonic development and tumorigenesis have not been well explored. Development of the placental villi is a crucial process involving many cellular activities, including immunity, proliferation, and cell adhesion. In this study, we designed a strategy to identify the gene expression pattern of villi development and to explo...

We investigated the passive mechanical properties of villi in ex vivo preparations of sections of the wall of the distal ileum from the brushtail possum (Trichosurus vulpecula) by using a flow cell to impose physiological and supra-physiological levels of shear stress on the tips of villi. We directly determined the stress applied from the magnitude of the local velocities in the stress inducin...
