This study aimed to assess the morphometry of enterocytes as well goblet cell-to-enterocyte ratio in different intestinal segments dogs with chronic enteropathies (CE). Histopathological samples from 97 were included (19 healthy juveniles, 21 adults, 24 protein-losing enteropathy (PLE), and 33 CE without PLE). Healthy adult small showed progressively reduced epithelial cell height aboral direct...
Sturgeon is one of the most important species of the Caspian Sea aquatics. Unfortunately, this species faces the threat of extinction today. This makes specific studies on any type of sturgeons more important than before. Studies like histological studies, radiology, and sonography, all require a complete understanding of the anatomy of this fish. Since pilot studies showed some misconceptions ...
Recent studies have shown that aberrantly expressed gastrin-releasing peptide (GRP) and its receptor (GRP-R) critically regulate tumor cell differentiation in colon cancers developing in humans and mice. This finding suggested that the ability of GRP/GRP-R to promote a well-differentiated phenotype in colon cancer might reflect a re-capitulation of a normal role in regulating intestinal organog...
Estuaries and bays are areas with a wide range of hydrodynamic and morphological phenomena. The existence of this diversity in environmental processes will lead to complex and sometimes unknown interactions in their structure. Understanding the behavior and environmental conditions of these beaches will improve the attitude of coastal users for better management of these areas. Many classificat...
Separate populations of M cells have been detected in the follicle-associated epithelium of Peyer's patches (PPs) and the villous epithelium of the small intestine, but the traits shared by or distinguishing the two populations have not been characterized. Our separate study has demonstrated that a potent mucosal modulator cholera toxin (CT) can induce lectin Ulex europaeus agglutinin-1 and our...
in this research,the authors conducted a study comparing two groups of male and female english language learners studying in a elt institute,in terms of their performance on their achievement test including listening comprehension,vocabulary,grammar,and reading comprehension and found no significant difference between the group except in listening comprehension part of the test in which the f...
in the present work, a simple and sensitive method was developed for determination of morphine and heroin using gold nanoparticles as resonance rayleigh scattering (rrs) and colorimetric technique’s probe. synthesized gold nanoparticles by sodium citrate reduction method have a negative charge layer on their surfaces because of self-assembled citrate anions on their surface. binding of morphin...
this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...
