Abstract:

Systemic circulatory dynamics are regulated by various negative feedback systems, including cardiac, arterial, venous, and renal functions, as well as autonomic nervous systems. The present novel four-quadrant presentation of their functions allows clear visualization of dynamic organ-to-organ interactions that can lead to a new circulatory equilibrium after therapeutic intervention. This new system physiological framework can serve as a useful guide for prompt and optimal management of circulatory malfunction.

Abstract:

INTRODUCTION: The mortality rate of the population from diseases of the circulatory system is one of the most pressing problems in the socio-economic development of the Russian Federation and its regions. Since mortality from diseases of the circulatory system ranks first among all causes of mortality in the population, this problem needs special attention and measures addressed to them. AIM: Conduct a comparative analysis of indicators of the level, structure and dynamics of mortality from diseases of the circulatory system of the population of the Voronezh region for 2010–2019.

Abstract:

The human fetal head is periodically compressed during labor. The resulting increase in intracranial pressure (ICP) may exceed the hydrostatic increase in mean arterial pressure (MAP), thereby decreasing cerebral perfusion pressure (CPP). We determined whether the cardiovascular system of near-term fetal sheep is capable of rapidly increasing MAP during periodic increases in ICP. In 12 chronically instrumented fetuses, we produced sinusoidal oscillations in ICP with a maximum of 52 +/- 1 mmHg (baseline MAP) and a minimum of 4 +/- 1 mmHg at a 3-min periodicity by ventricular fluid infusion and

Abstract:

At the onset of muscular exercise, the kinetics of pulmonary O2 uptake (V̇o2P) reflect the integrated dynamic responses of the ventilatory, circulatory, and neuromuscular systems for O2 transport and utilization. Muscle O2 uptake (V̇o2m) kinetics, however, are dissociated from V̇o2P kinetics by intervening O2 capacitances and the dynamics of the circulation and ventilation. We developed a multicompartment computational model (MCM) to investigate these dynamic interactions and optimized and validated the MCM using previously published, simultaneously measured V̇o2m, alveolar O2 uptake (V̇o2A),

Abstract:

a hydraulic circulatory duplicator is a hydraulic circuit, closed or open that physically reproduces one human district, along with the effects of any connected apparatus, on local fluid dynamics. such hydraulic circulatory duplicators are usually made up of rigid or deformable pipes, pressure loss generators, such as valves or sponge elements, compliant elements such as a pneumatic room, elastic elements, pumping elements, which may be centrifugal, axial, or roller, and tanks. all the elements are connected by joints. the systems are completed by transducers of pressure or flow, and systems f

Introduction. On the territory of the Altai territory there are four areas of falling of separating parts of space launch vehicles. For many years, these territories have been exposed to negative factors of rocket and space activities. In order to assess the possible impact of rocket and space activities on the health of the inhabitants of the Altai territory, living near the areas of falling of the separating parts of the launch vehicles, their medical examination is regularly carried out.The aim of the study is to assess the possible impact of rocket and space activities on public health.Mat

Abstract:

Abstract. Because of the fundamental role feedbacks play in determining the response of surface temperature to perturbations in radiative forcing, it is important we understand the dynamic characteristics of these feedbacks. Rather than attribute the aggregate surface temperature feedback to particular physical processes, this paper adopts a linear systems approach to investigate the partitioning with respect to the timescale of the feedbacks regulating global mean surface temperature in climate models. The analysis reveals that there is a dominant net negative feedback realised on an annual t

In dynamics from 2015 to 2020, general morbidity of the population of the Orenburg Region was characterized by the fact that the morbidity rates of respiratory diseases still ranked first, while diseases of the circulat

Abstract:

Using fluid-structure interaction algorithms to simulate the human circulatory system is an innovative approach that can provide valuable insights into cardiovascular dynamics. Fluid-structure interaction algorithms enable us to couple simulations of blood flow and mechanical responses of the blood vessels while taking into account interactions between fluid dynamics and structural behaviors of vessel walls, heart walls, or valves. In the context of the human circulatory system, these algorithms offer a more comprehensive representation by considering the complex interplay between blood flow a
