Rapidly and slowly progressive neuromuscular disease: differences in pulmonary function, respiratory tract infections and response to lung volume recruitment therapy (LVR)

BMJ Open Respiratory Research, 2022
Introduction Reduced lung volumes are a hallmark of respiratory muscle weakness in neuromuscular disease (NMD). Low respiratory system compliance (Crs) may contribute to restriction and be amenable to lung volume recruitment (LVR) therapy.

Genetics of sleep and sleep disorders [PDF]

Cellular and Molecular Life Sciences, 2007
Genetic factors affect sleep. Studies in twin pairs demonstrate that the strong hereditary influences on sleep architecture and some sleep disorders are transmitted through families. Evidence like this strongly suggests that sleep regulation receives significant influence from genetic factors.

Personality features ina sample of psychophysiological insomnia patients [PDF]

Arquivos de Neuro-Psiquiatria, 2003
The personality is the way people express themselves inside the environment they live. Sleep, quality or quantity, is a way of this physical and psychological expression of well being.

Cerebral blood volume and oxygen supply uniformly increase following various intrathoracic pressure strains

Scientific Reports, 2017
Intrathoracic pressure (ITP) swings challenge many physiological systems. The responses of cerebral hemodynamics to different ITP swings are still less well-known due to the complexity of cerebral circulation and methodological limitation.

Genome-wide screen for genes involved in Caenorhabditis elegans developmentally timed sleep [PDF]

, 2017
In Caenorhabditis elegans, Notch signaling regulates developmentally timed sleep during the transition from L4 larval stage to adulthood (L4/A) . To identify core sleep pathways and to find genes acting downstream of Notch signaling, we undertook the ...

Quantitative Changes in Muscular and Capillary Oxygen Desaturation Measured by Optical Sensors during Continuous Positive Airway Pressure Titration for Obstructive Sleep Apnea

Biosensors, 2021
Obstructive sleep apnea (OSA) is a common sleep disorder, and continuous positive airway pressure (CPAP) is the most effective treatment. Poor adherence is one of the major challenges in CPAP therapy. The recent boom of wearable optical sensors measuring

Are there sleep-specific phenotypes in patients with chronic fatigue syndrome? A cross-sectional polysomnography analysis [PDF]

, 2013
Objectives: Despite sleep disturbances being a central complaint in patients with chronic fatigue syndrome (CFS), evidence of objective sleep abnormalities from over 30 studies is inconsistent.

Numerical modelling of flow and transport in rough fractures

Journal of Rock Mechanics and Geotechnical Engineering, 2014
Simulation of flow and transport through rough walled rock fractures is investigated using the lattice Boltzmann method (LBM) and random walk (RW), respectively.

Sleep–Related Breathing Disorders in Adults: Recommendations for Syndrome Definition and Measurement Techniques in Clinical Research

, 2000
OBSTRUCTIVE SLEEP APNEA is a condition characterized by repetitive obstruction of the upper airway often resulting in oxygen desaturation and arousals from sleep.

On the genus "Asplenium" in the Iberian Peninsula" [PDF]

, 1983
The Asplenium species recorded from the Iberian peninsula comprise diploids and tetraploids, and of the latter, both auto- and allotetraploids occur. Evidence from the meiotic pairing behaviour of the chromosomes in synthetic hybrids is adduced to show ...
