Immunohaemostasis and the significance of immune reactions in the regulation of blood coagulation.

Introduction: This study was conducted to determine the specific features of the mutual influence of the immune and haemostatic systems in immunohaemostasis, the role of immune reactions in the regulation of blood coagulation, and the efficacy of modern methods of treating thrombosis and bleeding.

Methods: The study analysed relevant scientific sources on immunology and haematology and identified the specific features of the blood clotting process and the role of immune reactions in it.

Results: The study found that the immune system influences the haematological system through the interaction of blood clotting factors, platelets, plasminogen, endothelial cells with immune cells.

Partial Water Intrusion and Extrusion in Hydrophobic Nanopores for Thermomechanical Energy Dissipation.

Forced wetting (intrusion) and spontaneous dewetting (extrusion) of hydrophobic/lyophobic nanoporous materials by water/nonwetting liquid are of great importance for a broad span of technological and natural systems such as shock-absorbers, molecular springs, separation, chromatography, ion channels, nanofluidics, and many more. In most of these cases, the process of intrusion-extrusion is not complete due to the stochastic nature of external stimuli under realistic operational conditions. However, understanding of these partial processes is limited, as most of the works are focused on an idealized complete intrusion-extrusion cycle.

Holter ECG monitoring and platelets characteristics in patients with coronary artery disease and atrial fibrillation.

Objective: Aim: To check the relationships between platelet characteristics and Holter ECG monitoring results in patients with atrial fibrillation (AF) and coronary artery disease (CAD).

Patients And Methods: Materials and Methods: 300 investigated patients were separated into three groups: I (CAD) - 149 patients with CAD without arrhythmias, II (CAD and AF) - 124 patients with CAD and AF paroxysm, and the control group (CG) - 27 patients without CAD and arrhythmias.

Results: Results: In the II group was detected an increase in mean platelet volume (MPV) (9.

Sphere-shaped ZnO photocatalyst synthesis for enhanced degradation of the Quinolone antibiotic, Ofloxacin, under UV irradiation.

The sphere-shaped zinc oxide (ZnO) photocatalyst was synthesized by the homogeneous precipitation method, using Zn(CHCOO)·2HO as a zinc precursor and NHOH as a precipitating agent. The morphology and crystal structure of the prepared ZnO sample were studied by XRD, SEM, FT-IR, XPS, zeta potential measurements, and a low-temperature nitrogen adsorption-desorption technique. The optical characteristics of ZnO were determined by UV - Vis diffuse reflectance spectroscopy.

Quality-dependent performance of hydrophobic ZIF-67 upon high-pressure water intrusion-extrusion process.

Zeolitic imidazolate framework (ZIF) microporous materials have already been employed in many fields of energetic and environmental interest since the last decade. The commercial scale production of some of these materials makes them more accessible for their implementation in industrial processes; however, their massive synthesis may entail modifications to the preparation protocols, which may result in a loss in the optimization of this process and a drop in the material's quality. This fact may have implications for the performance of these materials during their lifetime, especially when they are used in applications such as energy dissipation, in which they are subjected to several operating cycles under high pressures.
