Assessment of Microcirculation and Microrheological Parameters of Blood in Patients With Type 2 Diabetes Mellitus Using Biophotonics Techniques.

In this study, the parameters of blood microcirculation and microrheology were measured using the methods of laser aggregometry and optical tweezers in vitro, as well as the method of digital capillaroscopy in vivo. It was shown that in patients suffering from type 2 diabetes mellitus, an increase in the number of RBC aggregates passing through the narrow capillaries leads to a significant decrease in the velocity of the capillary blood flow, which can be explained by the increased viscosity of the whole blood and decreased deformability of RBCs. Also, for the group of patients, a statistically significant increase in the rate of RBC aggregation and the hydrodynamic strength of aggregates, RBC aggregation and disaggregation forces were observed compared to the control group.

[Microcirculatory parameters in compensated and decompensated type 2 diabetes mellitus].

Aim: To reveal the features of microcirculatory parameters in compensated and decompensated type 2 diabetes mellitus (T2DM).

Subjects And Methods: A total of 196 patients with T2DM were examined and divided into 2 groups: 1) 52 patients (40.4% of men) aged 52.

Geomagnetic storm under laboratory conditions: randomized experiment.

The influence of the previously recorded geomagnetic storm (GS) on human cardiovascular system and microcirculation has been studied under laboratory conditions. Healthy volunteers in lying position were exposed under two artificially created conditions: quiet (Q) and storm (S). The Q regime playbacks a noise-free magnetic field (MF) which is closed to the natural geomagnetic conditions on Moscow's latitude.

Effect of zero magnetic field on cardiovascular system and microcirculation.

The effects of zero magnetic field conditions on cardiovascular system of healthy adults have been studied. In order to generate zero magnetic field, the facility for magnetic fields modeling "ARFA" has been used. Parameters of the capillary blood flow, blood pressure, and the electrocardiogram (ECG) monitoring were measured during the study.
