The lecture deals with the present-day views on the role of an inflammatory component in the development of atherosclerosis and accelerated formation of atherosclerotic lesions in autoimmune-aetiology vasculitis syndromes characteristic of rheumatic diseases. Both processes are typically manifested by lesions of the vascular wall in the form of inflammation, thrombosis, necrosis, and subsequent sclerotic alterations. The common links of the pathogenesis of these processes are associated with immune-system impairments, rheological and microcirculatory disorders, endothelial dysfunction, atherosclerosis, and dyslipoproteidaemia.

Shear stress plays a critical role in regulating physiological processes within microcirculatory systems. While particle imaging velocimetry is a standard technique for quantifying shear flow, uncertainty near boundaries and low resolution remain severe restrictions. Additionally, shear stress determination is particularly challenging in biofluids due to their significant non-Newtonian behaviors.

Was to conduct the analysis of patient's clinical observation with acute dinitrophenol poisoning, admitted to a toxicological department of CCH №6 of Izhevsk, Udmurt Republic in 2021 yr. In this clinical case report, a 19 years old girl, who took 20 tablets of dinitrophenol, illegally obtained in online-shop, died. The fatal outcome was realized by the uncoupling of oxidative phosphorylation mechanism and cellular respiration, which in its turn led to serious dystrophic changes in all organs and tissues.

Background: Physical activity at high-altitudes is increasingly widespread, both for tourist trekking and for the growing tendency to carry out sports and training activities at high-altitudes. Acute exposure to this hypobaric-hypoxic condition induces several complex adaptive mechanisms involving the cardiovascular, respiratory and endocrine systems. A lack of these adaptive mechanisms in microcirculation may cause the onset of symptoms of acute mountain sickness, a frequent disturbance after acute exposure at high altitudes.

The rheological properties of blood play an important role in regulating blood flow in micro and macro circulation. In thalassemia syndromes red blood cells exhibit altered hemodynamic properties that facilitate microcirculatory diseases: increased aggregation and reduced deformability, as well as a marked increase in adherence to the vascular endothelial cells. A personalized approach to treating thalassemia patients (transfusions, iron chelation, and splenectomy), has increased patients' life expectancy, however they generally present many complications and several studies have demonstrated the presence of high incidence of thromboembolic events.

Acute pancreatitis still means a serious challenge in clinical practice. Its pathomechanism is complex and has yet to be fully elucidated. Rheological properties of blood play an important role in tissue perfusion and show non-specific changes in acute pancreatitis.
