Tongue and Hyoid Bone Positions and Its Relations to the Mandibular Anterior Teeth: A Cone‐Beam Computed Tomography Study

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objectives This study aimed to investigate the position of the tongue and hyoid bone at rest according to incisal relationships using cone beam computed tomography and to examine whether dentoskeletal measurements are correlated with these positions.

Obstructive sleep apnea and cardiac arrhythmias

Annals of Thoracic Medicine, 2010
Sleep-disordered breathing (SDB), which includes obstructive sleep apnea (OSA) as its most extreme variant, is characterized by intermittent episodes of partial or complete obstruction of the upper airway, leading to cessation of breathing while asleep.

Effects of the angle of head‐down tilt on dynamic cerebral autoregulation during combined exposure to cephalad fluid shift and mild hypercapnia

Experimental Physiology, EarlyView.
Abstract Astronauts experience combined exposure to a cephalad fluid shift and mild hypercapnia during space missions, potentially contributing to health problems. Such combined exposure may weaken dynamic cerebral autoregulation. The magnitude of cephalad fluid shift varies between individuals, and dynamic cerebral autoregulation may be affected more ...

Optimizing cerebrovascular endothelial health through shear stress modulation

Experimental Physiology, EarlyView.
Abstract The endothelium plays a pivotal role in regulating cerebrovascular blood flow, and its dysfunction increases the risk of cerebrovascular disease. Endothelial shear stress, a primary mechanical stimulus for endothelial nitric oxide production, is a key modulator of vascular adaptation.

Applying lessons from limb muscle disuse and ageing to better understand ventilator‐induced diaphragm dysfunction

Experimental Physiology, EarlyView.
Abstract Mechanical ventilation (MV) is a life‐saving intervention applied to critically ill patients. A common consequence of MV is ventilator‐induced diaphragm dysfunction (VIDD), which is characterized by significant diaphragm atrophy and reduced contractile function. Older patients who receive MV are more likely to develop VIDD, have worse recovery,

Effect of live‐high, train‐low strategy induced by chronic low‐dose carbon monoxide exposure on haematological parameters and performance in trained individuals

Experimental Physiology, EarlyView.
Abstract Altitude training enhances haematological adaptations and endurance at sea level, typically requiring exposure to ∼2500 m altitude for 3–4 weeks. Emerging evidence suggests that low‐dose carbon monoxide (CO) inhalation might mimic hypoxia and might be used by elite athletes.

Carotid artery dissection linked to intermittent apnoeic swimming: A case–control study

Experimental Physiology, EarlyView.
Abstract Internal carotid artery (ICA) dissection is a rare and potentially devastating cause of cerebral ischaemia, initiated by an intimal tear or rupture of the vasa vasorum, that can lead to an intraluminal thrombus, vascular stenosis, occlusion, or dissecting aneurysm formation.

The hypoxic ventilatory response and arousal burden predict the magnitude of ventilatory long‐term facilitation in humans with obstructive sleep apnoea

Experimental Physiology, EarlyView.
Abstract The magnitude of progressive augmentation (PA) and ventilatory long‐term facilitation (vLTF) are two forms of respiratory plasticity that are enhanced in some humans with obstructive sleep apnoea (OSA). This response might be linked to repeated nocturnal exposure to intermittent hypoxia or other traits connected to OSA.
