In the third trimester of fetal development, software continues to increase signifi cantly in weight. The organ has already undergone formation architecture a complex alveolar- tubular gland, but processes morphofunctional diff erentiation both stromal- vascular component and parenchyma pancreas are still ongoing. Particularly active this period is process cells exocrine endocrine parts pancreas....

The secretin-stimulated human pancreatic duct secretes HCO(3)(-)-rich fluid essential for normal digestion. Optimal stimulation of pancreatic HCO(3)(-) secretion likely requires coupled activities of the cystic fibrosis transmembrane regulator (CFTR) anion channel and apical SLC26 Cl(-)/HCO(3)(-) exchangers. However, whereas stimulated human and guinea pig pancreatic ducts secrete ∼140 mM HCO(3...

Species of Carlina corymbosa L.,Carthamus dentatus Vahl. and Picnomon acarna (L.) Cass. are belonging to Asteraceae family. The purpose the study is determine anatomical structures these species in same tribe compare features. Samples root, stem leaf e-ach were collected, fixed examined using a light micros-cope. In addition, some features measured. Secondary growth was observed root cross sect...

Morphological, structural and developmental features of fruits and seeds of Mammea americana L. are here studied, with the purpose to give a proper classification of their fruit and embryo type and to contribute to future taxonomical and ecological studies. The fruit is a berry and the "rind" consists of the exocarp, represented by a periderm with lenticels, and by the parenchymatic mesocarp, w...

X-linked hypohidrotic ectodermal dysplasia (XLHED) is the most common of the ectodermal dysplasias, with a classic presentation of hypodontia, hypohidrosis, hypotrichosis and secretory gland hypoplasia. Mutations in the ectodysplasin gene (EDA) underlie XLHED with nearly 200 different mutations reported. EDA encodes a type 2 transmembrane protein of the TNF family (EDAA1), the active form of wh...

Problem statement: Histological and histochemical investigations on the salt glands of birds are very limited. The present study was performed to characterize the microanatomy and histochemistry of the salt glands of the Kentish plover (Charadrius alexandrines). Approach: Salt glands of the bird under study were fixed, dehydrated, cleared, impregnated and blocked out by paraffin wax. Paraffin s...

GP2 is a membrane-associated secretory protein originally identified in zymogen granules of pancreatic acinar cells. Recently, this glycoprotein has attracted attention as a marker substance of M cells of Peyer's patches and for its involvement in the selective uptake of pathological bacteria via M cells. When we stained the conjunctiva and tear ducts of mice using a GP2 antibody, all goblet ce...

Whereas in all other vertebrates the Müllerian ducts of genetic males are aborted during development, under the influence of Müllerian-inhibiting substance, in the caecilian amphibians they are retained as a pair of functional glands. It has long been speculated that the Müllerian gland might be the male accessory reproductive gland but there has been no direct evidence to this effect. The pres...

The nature and distribution of cell contacts have been examined in thin sections and freeze-fracture replicas of mammary gland samples from female C3H/Crgl mice at stages from birth through pregnancy, lactation, and postweaning involution. Epithelial cells of major mammary ducts at all stages examined are linked at their luminal borders by junctional complexes consisting of tight junctions, var...

Using primers against highly conserved regions of mammalian and bird aquaporins in RT-PCR experiments, we amplified products derived from duck (Anas platyrhynchos) nasal gland RNA that were identified as homologues of mammalian and chicken aquaporin 1 and aquaporin 5 cDNAs by sequencing. Using digoxigenin-labelled probes derived from these PCR products in northern blot analyses of mRNA isolated...
