[Experimental substantiation of medical device design for mechanical processing of adipose tissue].

Objective: To substantiate the medical device design for mechanical processing of adipose tissue.

Material And Methods: Enzymatic method using collagenase and mechanical method for obtaining the stromal vascular fraction (SVF) are compared. The authors emphasized the disadvantages of enzymatic method, such as high cost and duration of process.

Development, regeneration, and physiological expansion of functional β-cells: Cellular sources and regulators.

Pancreatic regeneration is a complex process observed in both normal and pathological conditions. The aim of this review is to provide a comprehensive understanding of the emergence of a functionally active population of insulin-secreting β-cells in the adult pancreas. The renewal of β-cells is governed by a multifaceted interaction between cellular sources of genetic and epigenetic factors.

Taxonomic diversity and abundance of enchytraeids (Annelida, Clitellata, Enchytraeida) in the Northern Palaearctic. 1. Asian part.

Background: Enchytraeids, or potworms, are tiny oligochaetes that are distributed worldwide in many terrestrial, freshwater and marine ecosystems. Despite their key role in the functioning of ecosystems, the diversity and abundance of Enchytraeidae are rarely studied due to the laborious process of species identification. The present study addresses this gap and sheds some light on the distribution and abundance of enchytraeids in the lands of the Northern Palearctic.

Method of prevention of post-operative peritoneal adhesions.

Objective: The purpose of the research was to assess the performance of the method of prevention of post-operative peritoneal adhesions (PAs) (author's method) in patients of different age groups.

Methods: Two hundred eighty-five patients were in total enrolled in the study. The patients of two age groups were divided into two groups: Group 1 (treatment group), where the author's method was used on 143 patients, and Group 2 (control group) 142 patients, where was used the standard approach of prevention of intra-abdominal adhesions.

Unexpected Room Temperature Ferromagnetism of a Ball-Milled Graphene Oxide-Melamine Mixture.

Nitrogen-doped carbon nanomaterial (NDCNM) was synthesized by grinding a mixture of graphene oxide and melamine in a planetary mill with both balls and milling chamber of zirconium dioxide. In the electron spin resonance spectrum of NDCNM, a broad signal with = 2.08 was observed in addition to a narrow signal at = 2.
