The transcytosis of lipids through enterocytes occurs through the delivery of lipid micelles to the microvilli of enterocytes, consumption of lipid derivates by the apical plasma membrane (PM) and then their delivery to the membrane of the smooth ER attached to the basolateral PM. The SER forms immature chylomicrons (iChMs) in the ER lumen. iChMs a...

Atherosclerosis is a complex non-monogenic disease related to endothelial damage in elastic-type arteries and incorrect feeding. Here, using cryodamage of endothelial cells (ECs) of rat abdominal aorta, we examined the role of the EC basement membrane (BM) for re-endothelization endothelial regeneration and its ability to capture low density lipopr...

Although the general structure of the barrier between the gut and the blood is well known, many details are still missing. Here, we analyse the literature and our own data related to lipid transcytosis through adult mammalian enterocytes, and their absorption into lymph at the tissue level of the intestine. After starvation, the Golgi complex (GC)...

The article highlights a complex of interendothelial connections of the lymphatic capillary of the rat intestinal villi, and focuses on the path of chylomicron transport through the lymphatic capillary wall after lipid loading. Material and methods. An experimental model was used to exclude a high lipid load; chymus from do- nor rats was injected w...

Rhynonyssidae is a family of endoparasitic hematophagous mites, which are still largely unknown even though they could act as vector or reservoir of different pathogens like dermanyssids. Sampling requirements have prevented deeper analysis. Rhinonyssids have been explored in a few host specimens per species, leading to undetailed morphological des...

Abstract. The research purpose was to analyze the microangioarchitectonics of intestinal villi, the microenvironment of the lymphatic capillary during lymph formation, which is important for understanding a number of pathologies of metabolic processes, lipid transport, lymph formation, immune defense, and others in particular. Material and research...

Here we accept and use a new morphology regarding the change of the old term "cribrum" to the new "ASPERO" (Dimov, 2020). The studying Rhinonyssid taxonomy is engaged many researchers all over the world. Russia is a place for much of the published research on the nasal mites. However, all territory is not good investigated yet. The present note is...

In spite of tremendous progress in deciphering the molecular mechanisms involved in intracellular transport in cell culture and in the test tube, many aspects of this process in situ remain unclear. Here, we examined lipid transcytosis in enterocytes in adult rats. Apical clathrin-coated buds and the ER exit sites were not found. After starvation,...

This book for the first time shows a more complete study of morphology of Rhinonyssid mites using scanning electron microscopy. Nasal mites from five genera (Larinyssus, Mesonyssus, Ptilonyssus, Rallinyssus and Sternostoma) are shown. In this study it is proposed to change the term "Cribrum" to the new term "Aspero" due to the incorrect use of the...

There is a great progress in understanding the cellular and molecular aspects of atherosclerosis, which is one of the leading causes of death. Yet, there are questions regarding the cellular and metabolic mechanisms that lead to atherogenesis. Among the many factors that influence this process, food plays a significant role. Among other factors tha...

Rhinonyssid mites are permanent parasites of birds that inhabit their respiratory tract. There are around 600 species described worldwide and almost all species of birds are found to have embedded rhinonyssid mites. Despite their presumed relevance, these mites are largely unstudied due to the difficulty in sampling them and, therefore, the majorit...

The article provides a review on studies of the molecular mechanisms of lipid transport in enterocyte of intestinal villi at the endoplasmic reticulum (ER)-Golgi complex stage. The main protein machines that ensure the assembly of prechylomicron (PC) in the ER and its further transfer to the Golgi complex are described. The role is shown of the mon...

The aim of the study: to develop teaching methods that will improve student performance.

The program at the department of anatomy provides additional classes for 1st and 2nd...

The intracellular transport is the most confusing issue in the field of cell biology. The Golgi complex (GC) is the central station along the secretory pathway. It contains Golgi glycosylation enzymes, which are responsible for protein and lipid glycosylation, and in many cells, it is organized into a ribbon. Position and structure of the GC depend...

The aim of the study: to understand the factors that ensure fluid absorption in the small intestine. The morphology of the villi of the small intestine and the ultrastructure of the enterocytes were studied using microphotographs. The enterocyte has a polarity in its morphological structure and in the processes occurring in different parts of the m...

Today in the scientific literature, very little information is devoted to the antenatal influence of pathogenic factors on the differentiation and development of the female reproductive system. That is why the study of this issue is one of the most popular in the field of gynecology, morphology and embryology. Due to many limitations, most studies...
