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...
In this paper we propose a new scheme for freeform shape optimization on arbitrary polygonal or polyhedral meshes. The approach consists of three main steps: (1) surface partitioning of polygonal meshes into different patches; (2) a new freeform perturbation scheme of using the Cox–de Boor basis function over arbitrary polygonal meshes, which supports multi-resolution shape optimization and doe...
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...

AIM Lymphocytic infiltration in the portal triads usually conceals the detection--in haematoxylin and eosin (H&E) stained sections--of bile ducts in two liver diseases: chronic hepatitis and primary biliary cirrhosis. The aim was to assess the number and the characteristics of the bile ducts in those diseases with the aid of an antibody to cytokeratin 7 (CK7). METHODS Consecutive sections fro...
We used pharmacological methods to test the hypothesis that female Dermacentor variabilis salivary ducts dilated when dopamine-stimulated and that dilation was nitric oxide-mediated. Stimulation with dopamine resulted in an increased diameter (19.7%) compared to unstimulated ducts (P<0.005). Pretreatment with L-NAME, an inhibitor of nitric oxide synthase, or cytochalasin D abolished the dilatio...
We present a technique for steganography in polygonal meshes. Our method hides a message in the indexed representation of a mesh by permuting the order in which faces and vertices are stored. The permutation is relative to a reference ordering that encoder and decoder derive from the mesh connectivity in a consistent manner. Our method is distortion-free because it does not modify the geometry ...
