  1. 1. Seagrass Respiration : An assessment of oxygen consumption patterns of temperate marine macrophytes

    Author : Lina M. Rasmusson; Mats Björk; Martin Gullström; Katharina Pawlowski; Jonas Collén; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Mitochondrial respiration; Photorespiration; Seagrass productivity; Zostera marina; Marine carbon budgets; Ruppia maritima; Ulva intestinalis; Plant Physiology; växtfysiologi;

    Abstract : In coastal seas, the abundance of marine macrophytes has profound influence on the flows of oxygen and inorganic carbon through the water. Vast amounts of carbon dioxide are taken up by photosynthesis and part of this is respired back into the water column. READ MORE

  2. 2. Ventilation and Lung Volume During Sleep and in Obstructive Sleep Apnea

    Author : Jonas Appelberg; Göran Hedenstierna; Christer Janson; Karl Franklin; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; Sleep; Ventilation; Sleep apnea syndromes; Snoring; Lung volume; Respiration; Computed tomography; Ventilatory response; Ventilation-perfusion; Airway closure; Fysiologi; Physiology; Fysiologi; klinisk fysiologi; Clinical Physiology; sleep; ventilation; sleep apnea syndromes; snoring; lung volume; respiration; computed tomography; ventilatory response; ventilation-perfusion; airway closure;

    Abstract : Obstructive sleep apnea (OSA) appears to affect up to 5% of the population. The extent to what pulmonary function awake and during sleep relates to obstructive breathing and hypoxemia during sleep in these patients is unclear. READ MORE

  3. 3. Importance of bacterial maintenance respiration and baseline respiration for development of coastal hypoxia

    Author : Kevin Vikström; Johan Wikner; Jan Karlsson; Josep M. Gasol; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Ecology; Respiration; Estuarine; Allochthonous; Maintenance; primary production; bacterial production;

    Abstract : Reduced oxygen concentrations and increasing hypoxic zones havebecome more common in the sea due to climate change andeutrophication. The main cause of oxygen loss in oxygenatedenvironments is respiration. READ MORE

  4. 4. Climate Change sensitivity of Photosynthesis and Respiration in Tropical Trees

    Author : Myriam Mujawamariya; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbon dioxide; Climate change; Drought; Elevation gradient; Photosynthesis; Respiration; Tropical montane forest; Tropical trees; Warming;

    Abstract : Tropical climate is getting warmer, with more pronounced dry periods in large areas. The productivity and climate feedbacks of future tropical forests depend on the ability of trees to acclimate their physiological processes, such as photosynthesis and leaf respiration, to these new conditions.

  5. 5. Nocturnal enuresis and rapid maxillary expansion : – long-term effect, prognostic variables, respiration during sleep and quality of life

    Author : Ingrid Jönson Ring; Bazargani Farhan; Tryggve Nevéus; Agneta Markström; Maria Ransjö; Uppsala universitet; []
    Keywords : Rapid maxillary expansion; nocturnal enuresis; sleep disordered breathing; respiration; polygraphic sleep recording; quality of life.; Medicinsk vetenskap; Medical Science;

    Abstract : Background:The orthodontic technique rapid maxillary expansion (RME) has been reported to have a potentially curative effect on nocturnal enuresis (NE). The mechanism behind this is unknown but could possibly be due to placebo and/or effects on respiration during sleep. READ MORE
