Published: June 2020

The aim is study the association of CDX2, CK20, CK7 with morphological changes in the gastric mucosa at children of aboriginal and newcomer population of the Republic of Tuva with gastritis.Materials and methods. We examined of children with gastroenterological complaints by 2 ethnic groups: 69 aboriginal and 34 immigrants. All underwent esophagogastroduodenoscopy with sampling of biopsies from the antral region and the body of the stomach. Diagnosis of gastritis was carried out according to the modified Sydney classification. H. pylori was determined of coloring the biopsies by Gimza. Expression of biomarkers was recorded by immunohistochemical method (CDX2, CK20, CK7). The analysis of the statistical significance of differences in qualitative characteristics was carried out using the criterion χ2.Results. We had determined the expression of CDX2 in 4 schoolchildren in the Republic of Tuva. This is can be examined as a marker for dynamic observation with a poor prognosis, because marker CDX2 tight connect with metaplasia and atrophy in gastric mucosa at adults. Association of the expression of CK20 and CK7 was established with the activity of gastritis, infection H. pylori, metaplasia of gastric mucosa, what more expressed by Tuva population. This has been testifying of the intensification proliferative processes in the gastric mucosa. This fact explaining the acceleration of progression the inflammatory process into the body of stomach. All it’s associated with an increased risk of dystrophy and atrophy at the gastric mucosa.Conclusion. CDX2 CK20, CK7 can to act as biomarkers of development the precancerous damage of stomach in schoolchildren of Tuva, especially by Tuvans. The presence of atrophy, metaplasia or CDX2 protein is a prognostically unfavorable factor.

Purpose and objectives:1. To study the blood supply of Peyer’s patches in the norm.2. To reveal the features of the blood supply of the Peyer’s patches in different sections of the small intestine.The peculiarity of the blood supply to the wall of the small intestine is that it depends on the morphostructure of the wall of this intestine.The distribution of arterial vessels in the submucosa is such that trey are divided into ordinal vessels (1, 2, 3 and 4 orders), which branch into layers and zones of the intestine, end also localized in Peyer’s patches.According to the results of the study, it was reveated that the features of the blood supply to the layers of the wall of the small intestine is that 4 zones of the wall of the intestine differ: mesenteric, antimesenteric (liber) and two lateral zones that differ in morphological and morphometric indicators.
Prospects for the use of biomarkers in the diagnosis of irritable bowel syndrome
Authors: Akhmedov V. A. , Sargsyan A. K. , Gaus O. V. 
Published: June 2020

Irritable bowel syndrome is a chronic functional disorder of the intestine, manifested by altered intestinal habits and recurrent abdominal pain in combination with two or more criteria: association with defecation, association with a change in the frequency of defecation, association with a change in the appearance of the stool. To date, IBS remains a diagnosis of exclusion that needs to be differentiated from a wide range of organic diseases. In recent years, a large number of publications have appeared on the research of etiopathogenesis, diagnosis and treatment of IBS. This literary review highlights the problems of searching for biomarkers of IBS as a way to solve the problem of diagnosis of this pathology and understanding the causes of its occurrence.
A Model to Predict Plant-available Water Content of Soils at Different Land Units in Bengkulu, Indonesia
Authors: Hermawan Bandi , Hasaanudin Hasanudin , Agustian Indra , Murcitro Bambang Gonggo 
Published: June 2020

Soil water availability to the plants is a very important physical property of soil that controls water and nutrient absorption by the plant. It is defined as the difference between the maximum amount of water the soil can hold and the minimum condition that the plant can no longer extract water from the soil. However, soil factors that control the plant available water content (PAWC) in the soil have not been fully understood. The present study aims to analyze the relations between particle-size distributions and organic carbon with the available water of the soil and to develop a model of predicting PAWC. Five soil profiles at different land units were described up to the depth of 100 cm. Ten undisturbed soil samples were taken using the stainless-made core sampler from 10 cm increments for the soil water holding capacity analysis. A similar number of disturbed samples were also provided from the same depths for soil texture and organic carbon analysis. Results showed that the variance in PAWC could be explained by sand and clay fractions (R2>0.35) but not by silt and organic carbon contents. Therefore, we were able to develop a model for the prediction of available water content in the soil from the sand and clay parameters. The model will help decision-makers be able to propose conservation and management strategies for PAWC in agricultural practices as well as for the soil moisture retention at civil works.
