INTEGRATIVE PHYSIOLOGY AS A TOOL FOR MEDICAL EDUCATION TRANSFORMATION

open access: yesProceedings of the Shevchenko Scientific Society: Medical Sciences, 2021
Given the rapid progress of modern science, integrative physiology holds a key place in medical education, as it studies patterns of human body functioning in terms of individual characteristics, epigenetic factors and endogenous effects on cellular ...

Waterlogging stress in cotton: Damage, adaptability, alleviation strategies, and mechanisms

open access: yesCrop Journal, 2021
Over the last few decades, waterlogging stress has increasingly threatened global cotton production. Waterlogging results in reduced soil oxygen, impairing the growth and development of this valuable crop and often resulting in severe yield loss or crop ...

An evolutionary perspective on conflict and compensation in physiological and functional traits [PDF]

open access: yesCurrent Zoology, 2014
Abstract Physiological and functional traits, especially those related to behavior and whole-organism performance capacities, are subject to a variety of both parallel and opposing natural and sexual selection pressures. These selection pressures show considerable interspecific variation, shaping contemporary behavioral and functional ...

RESPIRATORY ALKALOSIS

open access: yesАктуальные проблемы теоретической и клинической медицины, 2022
Respiratory alkalosis is a consequence of hyperventilation. There is a rapid removal of CO2 from the blood, and the pCO2 in the blood becomes below 35 mm Hg.

Viability costs of reproduction and behavioral compensation in western mosquitofish (Gambusia affinis). [PDF]

open access: yesPLoS ONE, 2014
The cost of reproduction hypothesis suggests that current reproduction has inherent tradeoffs with future reproduction. These tradeoffs can be both in the form of energy allocated to current offspring as opposed to somatic maintenance and future ...

Correct dosage of X chromosome transcription is controlled by a nuclear pore component

open access: yesCell Reports, 2021
Summary: Dosage compensation in Drosophila melanogaster involves a 2-fold transcriptional upregulation of the male X chromosome, which relies on the X-chromosome-binding males-specific lethal (MSL) complex.

Effects of sodium chloride on circadian period and temperature compensation of KaiC phosphorylation

open access: yesScientific Reports
The circadian clock is an internal timekeeping system that generates ~ 24-h cycles in physiology and behavior, maintaining a remarkably consistent period across physiological conditions and temperature1.

Molecular Mechanisms Regulating Temperature Compensation of the Circadian Clock

open access: yesFrontiers in Neurology, 2017
An approximately 24-h biological timekeeping mechanism called the circadian clock is present in virtually all light-sensitive organisms from cyanobacteria to humans.

Network balance via CRY signalling controls the Arabidopsis circadian clock over ambient temperatures

open access: yesMolecular Systems Biology, 2013
Circadian clocks exhibit ‘temperature compensation’, meaning that they show only small changes in period over a broad temperature range. Several clock genes have been implicated in the temperature‐dependent control of period in Arabidopsis.

Inter-population thermal variability and physiological response in the intertidal fish Scartichthys viridis (Blenniidae) Variabilidad térmica intrapoblacional y respuesta fisiológica en el pez intermareal Scartichthys viridis (Blenniidae)

open access: yesRevista Chilena de Historia Natural, 2007
Determining habitat conditions that generate individual physiological variability represents key basic knowledge to understand the direction of animal's responses to habitat change.
