The article presents some information about xanthomatosis, as well as about xanthomas of the stomach, which are benign formations, but their etiopathogenesis is unknown. Some believe that there is a relationship between xanthomas of the stomach and hyperlipidymia, diabetes, preneoplastic changes in the mucous membrane, age-related features of the gastric mucosa.The clinical case described in this report confi rms the existing point of view about xanthomas as markers of preneopastic changes in the gastric mucosa and its precancerous diseases.

The article presents a clinical case of intestinal epithelial dysplasia (tufting enteropathy), a rare disease which relates to congenital diarrheas, has a particular clinical presentation and is life-threating. The diagnosis was confirmed by histological examination and electronic microscopy of mucous membrane of small intestine. Additional evidence is substantiated for the existence of prenatal markers of intestinal epithelial dysplasia represented as polyhydramnios and intrauterine dilatation of fetal intestinal loops. These symptoms are considered to be a clinical hallmark of sodium and chloride diarrheas and are described in single cases in enteropathy called a microvillus inclusion disease.

The aim: The aim of the study is a statistical analysis of the mucosa of the stomach affected by Helicobacter pylori in young people studying at the university. Materials and methods: The work contains the results of the study of chronic gastritis of type B in university volunteer students. The study was attended by students of 1-4 courses, aged 17 to 25 years, a total of 50 people. Among them were 28 men and 22 women. Results: Various forms of chronic gastritis were found in the mucosa of the topographic-anatomical sections of the stomach, 90% of which were associated with Helicobacter pylori (HP). In all departments there is a different amount of common forms of chronic gastritis. In the pyloric section only atrophic gastritis was detected – 31.0 ± 8.5. Atrophic gastritis was also dominant on the lesser curvature – 32.3 ± 7.8, but its forms were significantly (p <0.5) less pronounced than in the pyloric section. In the area of the body, the above variants of chronic gastritis were found in 34.3 ± 8.7 cases, and the majority were flat erosive gastritis 51.0 ± 9.3. There is a tendency to reduce the degree of bacterial contamination of the gastric mucosa from its pyloric section and the lesser curvature to the walls of the body. With a decrease in the degree of bacterial contamination of the gastric mucosa, the degree of leukocyte infiltration also decreases. Between the degree of contamination of the mucous membrane of Helicobacter pylori and the degree of leukocyte infiltration of the mucous membrane, the Pearson correlation coefficient is rxy – 0,935, the correlation is very strong, the coefficient of determination is D=rxy^2 – 0,874, the statistically significant dependence on the probability is 0.99. Conclusions: Atrophic or hyperplastic gastritis associated with HP is found in the gastric mucosa, respectively, 90% of cases. The degree of bacterial contamination correlates with the degree of leukocyte infiltration of the gastric mucosa. Atrophic or hyperplastic gastritis Helicobacter pylori-associated is a common disease of people in young and working age.

Duplication of the gastrointestinal tract is a relatively rare malformation. The incidence is approximately 1 in 10 000 live births with the small intestinal duplication in most cases. Malformations with a long duplication part are considered technically complex. A successfully treated clinical case of the subtotal small intestinal duplication in a child is presented in the article. The mid-median mini-laparotomy was performed and a subtotal 1 meter length small intestinal duplication was revealed (from the Treitzs ligament to the ileum in 50 cm from the ileocolic valve). The proximal part of the intestinal duplication and its mucous membrane of the distal part with the common wall were completely removed. Histological examination found ectopia of the gastric mucosa and pancreatic tissue. Surgical treatment of this malformation is aimed at the complete removal of the duplication part due to possible ectopia of the gastric mucosa or pancreatic tissue. If the resection of an entire part of the intestinal duplication is technically impossible, the mucous membrane can be removed.

Abstract Background Aberrant DNA methylation is induced by aging and chronic inflammation in normal tissues. The induction by inflammation is widely recognized as acceleration of age-related methylation. However, few studies addressed target genomic regions and the responsible factors in a genome-wide manner. Here, we analyzed methylation targets by aging and inflammation, taking advantage of the potent methylation induction in human gastric mucosa by Helicobacter pylori infection-triggered inflammation. Results DNA methylation microarray analysis of 482,421 CpG probes, grouped into 270,249 genomic blocks, revealed that high levels of methylation were induced in 44,461 (16.5%) genomic blocks by inflammation, even after correction of the influence of leukocyte infiltration. A total of 61.8% of the hypermethylation was acceleration of age-related methylation while 21.6% was specific to inflammation. Regions with H3K27me3 were frequently hypermethylated both by aging and inflammation. Basal methylation levels were essential for age-related hypermethylation while even regions with little basal methylation were hypermethylated by inflammation. When limited to promoter CpG islands, being a microRNA gene and high basal methylation levels strongly enhanced hypermethylation while H3K27me3 strongly enhanced inflammation-induced hypermethylation. Inflammation was capable of overriding active transcription. In young gastric mucosae, genes with high expression and frequent mutations in gastric cancers were more frequently methylated than in old ones. Conclusions Methylation by inflammation was not simple acceleration of age-related methylation. Targets of aberrant DNA methylation were different between young and old gastric mucosae, and driver genes were preferentially methylated in young gastric mucosa.

Although aging enhances expression and tyrosine kinase activity of epidermal growth factor receptor (EGFR) in the gastric mucosa, there is no information about EGFR signaling cascades. We examined the age-related changes in mitogen-activated protein kinases (MAPKs) [extracellular signal-related kinases (ERKs), c-Jun NH2-terminal kinases (JNKs), and p38], an EGFR-induced signaling cascade, and activator protein-1 (AP-1) and nuclear factor-κB (NF-κB) transcriptional activity in the gastric mucosa of 4- to 6-, 12- to 14-, and 22- to 24-mo-old Fischer 344 rats. AP-1 and NF-κB transcriptional activity in the gastric mucosa rose steadily with advancing age. This can be further induced by transforming growth factor-α. The age-related activation of AP-1 and NF-κB in the gastric mucosa was associated with increased levels of c-Jun, c-Fos, and p52, but not p50 or p65. Total and phosphorylated IκBα levels in the gastric mucosa were unaffected by aging. Aging was also associated with marked activation of ERKs (p42/p44) and JNK1. In contrast, aging decreased p38 MAPK activity in the gastric mucosa. Our observation of increased activation of ERKs and JNK1 in the gastric mucosa of aged rats suggests a role for these MAPKs in regulating AP-1 and NF-κB transcriptional activity. These events may be responsible for the age-related rise in gastric mucosal proliferative activity.

Although in Fischer 344 rats aging is found to be associated with increased gastric mucosal proliferative activity, little is known about specific changes in the regulatory mechanisms of this process. To determine whether changes in cell cycling events could partly contribute to the age-related rise in gastric mucosal proliferative activity, the present investigation examines changes in cyclin-dependent kinase (Cdk2) activity and the regulation of this process in the gastric mucosa of Fischer 344 rats aged 4 (young), 13 (middle aged), and 24 (old) mo. We observed that aging is associated with a progressive rise in activity and protein levels of Cdk2 in the gastric mucosa. This is also found to be accompanied by a concomitant increase in cyclin E but not cyclin D1 levels. On the other hand, the levels of p21Waf1/Cip1 (total as well as the fraction associated with Cdk2), a nuclear protein that is known to inhibit different cyclin-Cdk complexes, are found to decline in the gastric mucosa with advancing age. In contrast, with aging, there was a steady rise in p53 levels in the gastric mucosa. We have also observed that the levels of phosphorylated retinoblastoma protein, a form that participates in regulating progression through the S phase, are markedly elevated in the gastric mucosa of aged rats. In conclusion, our data suggest that, in the gastric mucosa, aging enhances transition of G1 to S phase as well as progression through the S phase of the cell cycle. However, the age-related decline in p21Waf1/Cip1 in the gastric mucosa appears to be independent of p53 status.

It is known that gastric carcinogenesis results from the progressive changes from chronic gastritis to gastric atrophy, intestinal metaplasia, dysplasia, and invasive carcinoma. Several genetic and epigenetic alterations are involved in this process, and Helicobacter pylori (H. pylori) infection is believed to induce the initiation and progression of these steps. From an epigenetic point of view, H. pylori induces hypermethylation of genes involved in the development of gastric cancer and regulates the expression of various microRNAs (miRNAs). These H. pylori-related epigenetic changes are accumulated not only at the site of neoplasm but also in the adjacent non-cancerous gastric mucosa. Thereby, a state vulnerable to gastric cancer known as an epigenetic field defect is formed. H. pylori eradication can have an effective chemopreventive effect in gastric carcinogenesis. However, the molecular biological changes that occur in the stomach environment during H. pylori eradication have not yet been established. Several studies have reported that H. pylori eradication can restore infection-related changes, especially epigenetic alterations in gastric cancer-related genes, but some studies have shown otherwise. Simply put, it appears that the recovery of methylated gastric cancer-related genes and miRNAs during H. pylori eradication may vary among genes and may also differ depending on the histological subtype of the gastric mucosa. In this review, we will discuss the potential mechanism of gastric cancer prevention by H. pylori eradication, mainly from an epigenetic perspective.

The article draws a parallel between P. Kulish’s and I. Franko’s disposition to the age-related ideological autorevision. It is argued that, experiencing evolution of the worldview and creative work, revising his own early radical social impulses caused by the ‘national radical stage’ (Franko’s definition) of liberation movement in Halychyna, mature Franko in 1896 – 1907 got closer to the views of P. Kulish, especially those of the late period of his life (1874 – 1897). Like the latter, Franko defended the right to worldview evolution and changing views. These typological coincidences consisted also in the movement from the center-left forces to the right-centered ones; the transition to the primacy of the national idea over the social one; the drastic national self-criticism and simultaneous emphasis on the nation-building and state-building; gradual reorientation from the idea of social revolutionary development of society to evolutionary progress and moderate “means and ways of acting and speaking” (as Franko called it); the warnings against admiring communist illusion, against ochlocracy; and, finally, in the focus on the leading role of the nationally conscious Ukrainian intellectuals in the liberation struggle. Ideological and formal parallels between Franko and Kulish were revealed not only in the letters and journalism, but also in Franko’s practice of grounding his works on the materials of the national, biblical and Christian history and mythology (i. e. literary historicism and mythologism, focused on the present, the future and the author’s personality; symbolic autobiography). From this point of view it is worth to compare:  “Pisnia Budushchyny” (“Song of Future”) – “Try Braty” (“Three Brothers”); “Pokhoron” (“Funeral”), “Ivan Vyshenskyi” – “Velyki Provody” (“Great Farewell Procession”), “Marusia Bohuslavka”, “Dramovana Trylohiia” (“Drama-like Trilogy”); “Moisei” (“Moses”) – “Mahomet i Khadyza” (“Muhammad and Hadiza”), “Duma-Perestoroha, Velmy na Potomni Chasy Potribna” (“Warning Refl ections that will be Needed in Future”); “Strashnyi Sud” (“The Last Judgement”) – “Kulish u Pekli” (“Kulish in Hell”); “Slavianska Oda” (“Slavic Ode”) – “Tsarski Slova” (“Royal Words”).

The article presents some approaches to the development of educational programs in the field of road safety in General and Supplementary education of children and adolescents. It addresses some learning programs for children, adolescents and parents that are proved to be highly effective for teaching safe behaviour on the road. This article also focuses on the analysis of the features of working with "at-risk" children and teenagers with behavior problems-as a special social and age related category, exposed to the greatest risk in terms of traffic environment. The article focuses on the characteristics of attitudes typical for children and adolescents from the point of view of safety on the road, and it also outlines possible actions to develop integrated training and prophylaxis programs for this age group
