Loop analysis of blood pressure/volume homeostasis.

PLoS Computational Biology, 2019
We performed a mathematical analysis of the dynamic control loops regulating the vasomotor tone of vascular smooth muscle, blood volume, and mean arterial pressure, which involve the arginine vasopressin (AVP) system, the atrial natriuretic peptide ...

Resistance exercise breaks during prolonged sitting augment the blood flow response to a subsequent oral glucose load in sedentary adults

Experimental Physiology, EarlyView.
Abstract Sitting‐induced impairments in postprandial blood flow are an important link between sedentary behaviour and cardiometabolic disease risk. The objective of this work was to examine the effects of resistance exercise breaks (REB) performed every 30 min during an otherwise sedentary 3‐h period on the vasodilatory response to a subsequent oral ...

Regional changes in cerebral blood flow between the upright and supine posture and over 3 days of bed rest

Experimental Physiology, EarlyView.
Abstract A reduction in cerebral blood flow (CBF) has been observed during spaceflight and bed rest. We aimed to examine the magnitude and regional heterogeneity of the decrease in CBF during bed rest compared to posture changes on Earth. Seventeen participants (age, 29 ± 9 years, 7 females) were studied in the upright and supine posture and over 3 ...

The therapeutic role of exercise training during menopause for reducing vascular disease

Experimental Physiology, EarlyView.
Abstract Menopause marks a major milestone in female reproductive ageing. It is characterized by the cessation of ovarian function and a concomitant decline in hormones such as oestradiol. Subsequently, females undergoing menopausal transition experience a progressive increase in cardiovascular and cerebrovascular disease risk.

Use of Infrared Thermography and Heart Rate Variability to Evaluate Autonomic Activity in Domestic Animals

Animals
Most of the responses present in animals when exposed to stressors are mediated by the autonomic nervous system. The sympathetic nervous system, known as the one responsible for the “fight or flight” reaction, triggers cardiovascular changes such as ...

How hot is too hot for people? A review of empirical models of perceptual, physiological and functional limits of human heat tolerance

Experimental Physiology, EarlyView.
Abstract How hot is too hot for people? This is a question that human thermal physiologists are asked often by a variety of knowledge users across the public and private sectors, who have grown aware of the negative impact of global warming on people's health and quality of life.

[Endothelial vasomotor dysfunction in some forms of systemic vasculitis].

Terapevticheskii arkhiv, 2007
To study vascular endothelium in patients with systemic vasculitis (SV) with non-invasive methods.A total of 65 SV patients entered the trial: 20 patients with Henoch-Schonlein purpura (HSP), 20 patients with thromboangitis obliterans (TO), 10 patients with polyarteritis nodosa (PN), 15 patients with Takayasy's arteritis (TA).

The acute effect of two exercise modalities on neurocognitive responses in postmenopausal women: A randomized controlled trial

Experimental Physiology, EarlyView.
Abstract Menopause‐related cognitive decline, often worsened by vasomotor symptoms (VMS), might be mitigated by high cardiorespiratory fitness (CRF). Although acute exercise supports neurocognitive function, its effects vary by exercise and individual characteristics.

DEVELOPMENTAL FEATURES OF THE SYSTEM OF REGULATION OF HEART RATE IN A MALE BODY IN STAVROPOL

Наука. Инновации. Технологии, 2022
In the mechanisms of regulation of heart rate in men ontogenetic differences. Analysis of the activity of the autonomic nervous system links found fundamentally different regulatory mechanisms - trophotropic in adolescence and ergotrop - in the mature ...

Individuals with persisting post‐concussion symptoms with physiological subtype demonstrate altered cardiovascular and autonomic responses to face cooling

Experimental Physiology, EarlyView.
Abstract Individuals with persisting post‐concussion symptoms with physiological subtype (PPCS‐P) demonstrate exercise intolerance due to exacerbation of concussion‐like symptoms during incremental exercise. We tested the hypothesis that individuals with PPCS‐P (n = 12) would have a blunted cardiac autonomic response to face cooling compared to healthy
