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

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

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.

The use of heliox in critical care
International Journal of Critical Illness and Injury Science, 2014 This paper reviews the medical use of helium oxygen mixture in obstructive airway disease in patients with croup, narrow endotracheal tubes (ETTs), respiratory distress syndrome, asthma, bronchiolitis, as well as patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) and acute lung injury.

Heliox no tratamento do mal asmático: relato de casos
Revista Brasileira de Terapia Intensiva, 2016 RESUMO O hélio foi descoberto em 1868 pelo astrônomo francês Pierre-Jules-César Janssen e teve seu uso terapêutico pela primeira vez na obstrução das vias aéreas, feito por Barach, quase 70 anos depois, em 1934.

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.

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 ...

Heliox inhalation therapy for bronchiolitis in infants
Cochrane Database of Systematic Reviews, 2008 Acute viral bronchiolitis is associated with airway obstruction and turbulent gas flow. Heliox, a mixture of oxygen and the inert gas helium, may improve gas flow through high-resistance airways and decrease the work of breathing.To assess heliox in addition to standard medical care for acute bronchiolitis in infants.We searched the Cochrane Central ...
