BACKGROUND/PURPOSE The origin of cholangiolocellular carcinoma (CoCC) is still controversial. To solve this problem, morphometric and immunohistochemical features of CoCC were examined. MATERIALS AND METHODS Cancerous ducts: 15 CoCC lesions from 13 resected and two autopsied cases. Non-neoplastic ducts: 20 specimens of non-cancerous areas of eight resected CoCC cases and of 12 resected hepato...

Rat pancreases were minced and treated with collagenase or collagenase supplemented with chymotrypsin to yield a mixture of ducts, islets, acinar cell clusters, blood vessels, and nerves. Histologically and ultrastructurally, the isolated tissues resembled their in situ counterparts in most respects, the major difference being the destruction of the basement membranes (basal laminae). Ducts ran...

Structure and distribution of antennal sensilla were studied in males 19 species the caddisfly family Hydropsychidae by using scanning electron microscopy (SEM). Eleven types found: long trichoid, chaetoid, thick curved coronary, basiconic, styloconic four pseudoplacoid (mushroom-like, auricillic, ribbed, T-shaped). Thick ribbed pseudoplacoid, T-shaped found only Macronematinae. The great diver...

A numerical study of steady-state, fully developed, MHD duct flows is presented for the case of an applied transverse magnetic field and a two-dimensional variation of the flow parameters in the plane perpendicular to the flow direction, with no variations in fluid properties. Solutions are found for (i) rectangular ducts with no obstacles and (ii) rectangular ducts containing thin flat plates,...

Objectives: 1) to determine the elasticity of normal breast tissue (parenchyma and premammary adipose tissue) in healthy women using ultrasound two-dimensional shear wave elastography (2D-SWE); 2) reveal a possible correlation between increased stiffness parenchyma hyperprolactinemia patients with mastodynia mastopathy; 3) evaluate ability Vitex agnus-castus drug reduce glandular tissue; 4) obj...

In mammals formation of a sinus vagina is inhibited in the male by endogenous testosterone from the embryonic testes. To answer the question which morphogenetic events during formation of the vagina are influenced by testosterone, we explanted genital tracts of mouse embryos in the indifferent stage of development in organ culture. Half of the explants were treated with testosterone and therefo...

Ducts penetrating the fire compartment are passageways for spreading flames and smoke of igniting deposits attached to inside or fires from outside. Fires through ducts have a fast flame propagation speed difficult extinguish quickly because high-temperature heat. Therefore, in this study, improve risk ducts, need institutional improvement is confirmed by analyzing cases, comparing domestic for...
