Mayer-von-Rokitansky-Küster-Hauser syndrome (MRKHS) is characterized by vaginal agenesis with variable Müllerian duct abnormalities. The Abbè-McIndoe technique is considered a valid treatment option for vaginoplasty but no consensus has been reached on what material should be used for the neovagina canal wall lining. We report the first case of autologous vaginal tissue transplantation in a 28-...

Due to the unique hydrothermal environments, frost heave failure of concrete lining water conveyance canals in cold regions is still frequent. The deformation after heaving and stress distribution calculated by mechanical model can be reference for design. However, previous research mainly focused on cross-section while having little attention longitudinal nonuniform damage. In this study, a bo...

Frost heaving damage of canal lining in cold and dry areas is one the important causes leakage. In this paper, based on bending theory thin plate, a mechanical model under action frost force established solved. Through parametric engineering case analysis, following conclusions are drawn: force, moment, shear internal slope plate show nonuniform distribution, maximum values moment Mx normal str...

two types, that lining the cervical canal becoming columnar and, by invagination, forming a system of mucus-secreting glands, that covering the vaginal portion becoming squamous and laminated. At birth, the boundary between these two epithelia normally lies just within the lips of the external os, so that no glandular tissue is visible from the vagina. Occasionally, by faulty development, the c...

THE detailed structure of the trabecular wall of Schlemm's canal in man has previously been illustrated by means of teased flat preparations and thin paraffin sections (Speakman, 1959a, b). Features of interest were deep grooves lined with endothelial cells, openings 5-10 u in diameter which communicated with deeper spaces in the meshwork, and numerous vacuoles or spaces in the endothelial cell...

Four major areas of the urogenital system of Echinopardalis atrata are examined: (1) capsular protonephridial system, (2) uterine bell complex, (3) uterus, (4) vagina. Photomicrographs of cross sections from wax preparations depict morphological changes along the length of this system. Diagrammatic illustrations show relationships between excretory ducts and oviducts in the uterine bell complex...

Schlemm's canal (SC) is a unique vascular structure that functions to maintain fluid homeostasis by draining aqueous humor from the eye into the systemic circulation. The endothelium lining the inner wall of SC has both blood and lymphatic vascular characteristics, thus prompting exploration of the development and regulation of this unique channel. In this issue of the JCI, back-to-back papers ...

Purpose: justification of irrigation canal impervious linings use with new materials and methods for their calculation. Materials methods. The proposed improved designs canals were the research. To determine specific filtration flow, calculation free backed concrete-film damage in polymer geomembrane, taking into account moisture contours partial soil saturation water at base used. Results.
