Pancreatic islets are highly vascularized mini-organs, and vascular endothelial growth factor (VEGF)-A is a critical factor in the development of islet vascularization. To investigate the role of VEGF-A and endothelial cells (ECs) in adult islets, we used complementary genetic approaches to temporally inactivate VEGF-A in developing mouse pancreatic and islet progenitor cells or in adult β-cell...

BACKGROUND/AIMS The aim of this study was to generate an axially vascularized bone substitute. The arteriovenous (AV)-loop approach in a large-animal model was applied in order to induce axial vascularization in a clinically approved processed bovine cancellous bone (PBCB) matrix of significant volume with primary mechanical stability and to assess the course of increasing axial vascularization...

BACKGROUND In the presence of a thin and narrow zone of gingival tissue root recessions caused by trauma or inflammatory reactions seem to be a common feature of the buccal tissue morphology. The surgical coverage is mainly indicated for aesthetic reasons and may be accomplished with pedicled flaps in conjunction with or without the use of connective tissue grafts. AIM The purpose of the pres...

STUDY QUESTION Is there an association between chorionic villous vascularization, ultrasound findings and corresponding chromosome results in early miscarriage specimens from a cohort of recurrent pregnancy loss patients? SUMMARY ANSWER We did not find a significant difference in vascularization scores of chorionic villi between embryonic, yolk sac or empty sac miscarriages, or between euploi...

The diversity of the floral characters in 25 species Brassicaceae representing seven tribes was studied through tracing their organs vascularization. aim present study is to explore contribution micro-floral understanding relationships among as well evolutionary trends calyx, corolla, androecium and gynoecium. It concluded that vascularization sepals, petals, stamens, nectaries carpels consider...

The role of Doppler in the assessment of fetal and placental blood flow is well-established1. However, as exemplified by the large variability of results published in the literature, its role in the evaluation of uterine and ovarian hemodynamics is not so clearly defined. Velocimetric indices such as pulsatility index and resistance index have been shown to provide useful information on uterine...

in the present report, diagnosis and treatment of a case with follicular ovarian cysts in a 5-year-old persian queen cat is described. in response to palpation of spines, the queen cat presented herself in lordosis and danced up and down with her rear legs. trans-abdominal ultrasonography examination showed 2 cysts  in the left ovary of the queen. serum estrogen assay indicated elevated level o...

TEis problem has been of only moderate interest to research workers, and publications and monographs on the subject have been sporadic, though a few well-known names must be cited here (Leber, 1865a, b, 1872, 1903; Magitot, 1908, 1947; Behr, 1935; Wolff, 1939, 1940, 1948). The findings being very diverse, it seemed appropriate to try to find experimentally the normal vascular anatomy of the opt...
