Objective: Aim: The aim is to study the main factors of youth's Internet dependence formation.
Patients And Methods: Materials and Methods: We conducted psychodiagnostic examination of students in the National Academy of Internal Affairs. The research involved 154 students: full-time students aged 18-25 (n = 78) and part-time students aged 26-35 (n = 76).
Objective: Aim: The aim is to study the motivation of students towards Internet dependent behavior and develop practical recommendations for improving a set of measures for its prevention.
Patients And Methods: Materials and Methods: The research involved 154 students of the National Academy of Internal Affairs. Research methods: analysis and generalization of literature sources, questionnaire, statistical methods.
Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) is a common clinical problem, leading to significant morbidity and mortality, and no effective pharmacotherapy exists. The problem of ARDS causing mortality became more apparent during the COVID-19 pandemic. Biotherapeutic products containing multipotent mesenchymal stromal cell (MMSC) secretome may provide a new therapeutic paradigm for human healthcare due to their immunomodulating and regenerative abilities.

The aim of our study was to develop an easy-to-use placental multipotent mesenchymal stromal cell (MMSC) secretome-based chitosan hydrogel (MSC-Ch-gel) and estimate its antimicrobial and regenerative activity in -infected burn wounds in rats.
Methods: Proteomic studies of the MMSC secretome revealed proteins involved in regeneration, angiogenesis, and defence responses.

Gold nanoparticles and their conjugates have significant potential in the field of diagnosis of various diseases due to their SPR, which enhances light scattering and absorption. Conjugates of gold nanoparticles with various ligands can be used for imaging biomolecules or detecting malignant neoplasms at an early stage. This study focuses on the construction of composite (or hybrid) phospholipid-gold nanoparticles using soy phosphatidylcholine and a targeted ligand (folic acid derivative) to attach specific targeting properties.

The term "dysfunctional HDL" describes HDLs with impaired protective properties. Cholesterol efflux capacity (CEC) of HDL is reduced in patients with atherosclerosis, but the exact mechanisms underlying this impairment are not well characterized.
View Article and Find Full Text PDFIt is well known that blood lipoproteins (LPs) are multimolecular complexes of lipids and proteins that play a crucial role in lipid transport. High-density lipoproteins (HDL) are a class of blood plasma LPs that mediate reverse cholesterol transport (RCT)-cholesterol transport from the peripheral tissues to the liver. Due to this ability to promote cholesterol uptake from cell membranes, HDL possess antiatherogenic properties.

Blood plasma was incubated with earlier elaborated PL nanoparticles emulsion with the particle diameter up to 30 nm, and HDL cholesterol efflux capacity of apo B-depleted plasma was studied. Using macrophages THP-1 preloaded 3H-cholesterol were used.

First, it concerns their ability to accept cholesterol (CH) from macrophages - the basis of antiatherogenic action of HDL. This ability was assessed ex vivo - by activity of cell cholesterol (CH) efflux to HDL or into patient's serum.

The results of experimental and clinical investigations aimed at revealing of new pharmacological targets of dyslipidemias correction were analyzed. The approaches for activation of high density lipoproteins functionality are described.

Efficacy of treatmernt was evaluated by the LNT test (link numbers test), and standard liver plasma markers (ALT, AST, GGT, AP). The LNT test in patients with encephalopathy showed better improvement after 5 days course of Phos-pholipovit than after standard therapy.

Activation of proteolytic enzymes already on the stage of surgical trauma leads to the formation in the operative wound of the focus of endotoxicosis which depresses antitryptic activity of injured tissues and thus promotes the development of purulent complications. The study of the above indexes at the early stages of acute period may serve as a diagnostic test while estimating a severity of operative wound and allows to make prognosis of the development of purulent complications.

A case of management of a 10-month-old baby suffering from generalized eczema is described. The following methods used for active therapy-- tissue detoxication, hemosorption, thoracic duct drainage with lymphorrhea, lymphapheresis and lymphosorption and lymph cells removal from the body have led to a stable positive effect, i.e.
