The Biophysical Modeling of the Transport Phenomena in the Living Systems

open access: yesTechnium: Romanian Journal of Applied Sciences and Technology, 2020
This article describes the principles of biological transport. The transport phenomena mean the variation in time and space of generalized forces when they generate flows for which conservation laws apply. After we describes: mass-, impulse-, energy- and electric-charge-transport and their mathematical characteristic equations.

Biophysical phenomena in blood flow system in the process of indirect arterial pressure measurement [PDF]

open access: yesCardiometry, 2012
The idea of indirect arterial pressure measurement with the help of occlusive cuff belongs to Riva-Rocci. However, the phenomenon of noise appearing and disappearing in the blood flow distal of the brachial artery compression during the equality moments of occlusive, systolic and diastolic pressure was called Korotkov sounds.

Chronobiology Meets Quantum Biology: A New Paradigm Overlooking the Horizon?

open access: yesFrontiers in Physiology, 2022
Biological processes and physiological functions in living beings are featured by oscillations with a period of about 24 h (circadian) or cycle at the second and third harmonic (ultradian) of the basic frequency, driven by the biological clock.

A Systematic Review of Continuum Modeling of Skeletal Muscles: Current Trends, Limitations, and Recommendations

open access: yesApplied Bionics and Biomechanics, 2018
Finite elasticity theory has been commonly used to model skeletal muscle. A very large range of heterogeneous constitutive laws has been proposed. In this review, the most widely used continuum models of skeletal muscles were synthetized and discussed ...

Role of Cell Surface Hydrophobicity in the Pathogenesis of Medically-Significant Fungi

open access: yesFrontiers in Cellular and Infection Microbiology, 2021
Cell surface hydrophobicity (CSH) is an important cellular biophysical parameter which affects both cell-cell and cell-surface interactions. In dimorphic fungi, multiple factors including the temperature-induced shift between mold and yeast forms have ...

Abortive and propagating intracellular calcium waves: analysis from a hybrid model. [PDF]

open access: yesPLoS ONE, 2015
The functional properties of inositol(1,4,5)-triphosphate (IP3) receptors allow a variety of intracellular Ca(2+) phenomena. In this way, global phenomena, such as propagating and abortive Ca(2+) waves, as well as local events such as puffs, have been ...
