RADIATION AND HYPOXIA STUDIES: EFFECTS OF HIGH-ENERGY ATMOSPHERIC PARTICLES ON BIOLOGICAL ORGANISMS AND POSSIBILITIES OF THEIR REHABILITATION [PDF]

open access: yesBiotechnologia Acta, 2023
The influences of cosmic radiation on atoms and molecules in the Earth's atmosphere were observed with subsequent transformation of atoms, molecules of gases, as well as development of states of oxygen deficiency (hypoxic) in biological organisms, some ...

Fluid-structure interaction simulation of pulse propagation in arteries : numerical pitfalls and hemodynamic impact of a local stiffening [PDF]

open access: yes, 2014
When simulating the propagation of a pressure pulse in arteries, the discretization parameters (i.e. the time step size and the grid size) need to be chosen carefully in order to avoid a decrease in amplitude of the traveling wave due to numerical ...

Mechanisms of exercise-induced improvements in the contractile apparatus of the mammalian myocardium [PDF]

open access: yes, 2010
One of the main outcomes of aerobic endurance exercise training is the improved maximal oxygen uptake, and this is pivotal to the improved work capacity that follows the exercise training.

Single-leg cycling to maintain and improve function in healthy and clinical populations

open access: yesFrontiers in Physiology, 2023
Exercise with reduced muscle mass facilitates greater muscle-specific adaptations than training with larger muscle mass. The smaller active muscle mass can demand a greater portion of cardiac output which allows muscle(s) to perform greater work and ...
