Unsaturation in the air spaces of leaves and its implications

Plant, 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

Heliox Protects SH-SY5Y Cells from Oxygen-Glucose Deprivation/Reperfusion-Induced Ferroptosis

Journal of Integrative Neuroscience
Background: Heliox shows protective effects against acute focal ischemia-reperfusion injury in the brain. However, further research is needed to unveil the intricate molecular mechanisms involved.

Fast hyperbaric decompression after heliox saturation altered the brain proteome in rats. [PDF]

PLoS ONE, 2017
Better understanding of the physiological mechanisms and neurological symptoms involved in the development of decompression sickness could contribute to improvements of diving procedures.

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

Veterinary 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.

Hemoglobin During and Following a 4-Week Commercial Saturation Dive to 200 m

Frontiers in Physiology, 2019
Commercial saturation divers must acclimatize to hyperbaric hyperoxia in their work environment, and subsequently readjust to breathing normal air when their period in saturation is over.

Pediatric pulmonology year in review 2023: Physiology

Pediatric 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.

Heliox for asthma in the emergency department: a review of the literature [PDF]

Emergency Medicine Journal, 2004
January 2002 saw the relaunch by BOC of Heliox, a gaseous mixture of helium and oxygen, for the use in a wide range of respiratory conditions. Despite a lapse of over 65 years since it was first used, and a large number of studies and case reports advocating its use, it remains an enigma, its use sporadic, and its role undefined. This paper reviews the

Small airways’ function in Obstructive Sleep Apnea-Hypopnea Syndrome

Pulmonology, 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.

Severe bronchospasm and acute respiratory failure associated with inhaled prostacyclin therapy

Pulmonary Circulation, Volume 14, Issue 2, April 2024.
Abstract Prostacyclin therapy is a mainstay of the management of pulmonary arterial hypertension (PAH). Inhaled prostacyclins present safe and effective options for the management of PAH that limit systemic side effects. We describe the first reported case of life‐threatening bronchospasm and acute respiratory failure associated with inhaled ...

Ostwald ripening for air bubbles and decompression illness: phenomenological aspects in diving [PDF]

arXiv, 2018
The Ostwald ripening phenomenon for gas bubbles in a liquid consists mainly in gas transfer from smaller bubbles to larger bubbles. An experiment was carried out in which the Ostwald ripening for air bubbles, in a liquid fluid with some rheological parameters of the human blood, is reproduced.
