To what extent do physiological tolerances determine elevational range limits of mammals?

open access: yesThe Journal of Physiology, Volume 602, Issue 21, Page 5475-5484, 1 November 2024.
Abstract figure legend Hypothetical relationship between elevational range limits and capacity for aerobic thermogenesis (thermogenic maximal oxygen uptake) in hypoxia. In this hypothetical comparison between highland and lowland sister species, which is consistent with empirical data for small mammals, the species with the higher elevational range ...

MITOCHONDRIAL OXIDATIVE CAPACITIES: Does functional capacity match maximum physiological demand? [PDF]

open access: yes, 2014
The oxygen-dependent processes of ATP synthesis in mitochondria is same in all mammals and birds (endothermic animals). However, some endothermic species have higher maximum O2 consumption rate per unit mass (VO2 max/Mb) than others during aerobic ...

Small airways’ function in Obstructive Sleep Apnea-Hypopnea Syndrome

open access: yesPulmonology, 2021
Introduction and objectives Most of the studies of the pathophysiology of Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS) focus on the collapsibility and obstruction of the upper airways.

The physiology and biomechanics of avian flight at high altitude [PDF]

open access: yes, 2006
Many birds fly at high altitude, either during long-distance flights or by virtue of residence in high-elevation habitats. Among the many environmental features that vary systematically with altitude, five have significant consequences for avian flight ...

Unsaturation in the air spaces of leaves and its implications

open access: yesPlant, Cell &Environment, Volume 47, Issue 10, Page 3685-3698, October 2024.
Abstract Modern plant physiological theory stipulates that the resistance to water movement from plants to the atmosphere is overwhelmingly dominated by stomata. This conception necessitates a corollary assumption—that the air spaces in leaves must be nearly saturated with water vapour; that is, with a relative humidity that does not decline materially

Conductivity of Silicon Inversion Layers: comparison with and without in-plane magnetic field

open access: yes, 2004
A detailed comparison is presented of the temperature dependence of the conductivity of dilute, strongly interacting electrons in two-dimensional silicon inversion layers in the metallic regime in the presence and in the absence of a magnetic field.

Surgical management of brachycephalic obstructive airway syndrome: An update on options and outcomes

open access: yesVeterinary Surgery, Volume 53, Issue 7, Page 1173-1184, October 2024.
Abstract Dogs with a brachycephalic conformation often experience a collection of abnormalities related to their craniofacial conformation, which can lead to a variety of clinical signs such as stertor, exercise intolerance, respiratory distress, and gastrointestinal signs such as regurgitation, among others.

Pediatric pulmonology year in review 2023: Physiology

open access: yesPediatric Pulmonology, Volume 59, Issue 7, Page 1856-1861, July 2024.
Abstract Application of the principles of pulmonary physiology and lung development to the care and management of respiratory disease in children is a distinguishing feature of pediatric pulmonology. In 2023, this was evident in numerous publications in Pediatric Pulmonology and other journals. This review will highlight some of the papers in this area.
