Hematological and Genetic Predictors of Daytime Hemoglobin Saturation in Tanzanian Children with and without Sickle Cell Anemia. [PDF]

, 2013
Low hemoglobin oxygen saturation (SpO2) is common in Sickle Cell Anemia (SCA) and associated with complications including stroke, although determinants remain unknown.

Evaluation of Oxygen Saturation by Pulse-Oximetry in Mouth Breathing Patients [PDF]

Acta Medica Iranica, 2010
Mouth breathing might not always result in hypoxia, but can contribute to it. The aim of the present study was to determine the effect of mouth breathing on hypoxia. Based on a pilot study, 323 patients with mouth breathing were selected.

Bypassing Heteronuclear MRI: Metal‐Free Organosilicon Nanotracers for Background‐Free Hotspot 1H Imaging on Clinical Hardware

Advanced Science, EarlyView.
Organosilicon micelles enable background‐free molecular magnetic resonance imaging (MRI) while remaining fully compatible with standard proton (1H) hardware. By exploiting a spectrally silent 1H window at ∼0 ppm, the silicone nanotracer allows hotspot detection by 1H chemical‐shift imaging (CSI) without metals or heteronuclei, enabling direct overlay ...

An Investigation of Sleep Macro‐ and Microarchitecture by APOE Genotype

Annals of Neurology, EarlyView.
Objectives Apolipoprotein E ε4 (APOE ε4), a robust genetic risk factor for Alzheimer's disease (AD) is associated with functional connectivity deficits and amyloid pathology in brain regions involved in sleep regulation. Thus, alterations in sleep architecture may be one pathway through which ε4 contributes to Alzheimer's disease vulnerability. However,

Safety and pharmacokinetics of mosliciguat, a new, inhaled soluble guanylate cyclase activator, in healthy adult subjects

British Journal of Clinical Pharmacology, EarlyView.
Abstract Aim Mosliciguat (BAY 1237592), the first soluble guanylate cyclase (sGC) activator in a dry powder inhaler (DPI), could potentially treat pulmonary hypertension with a more targeted delivery than systemic sGC stimulators. We report safety and tolerability of mosliciguat in healthy men.

A Large Retrospective Study to Evaluate Utility of Zephyr Covered Stent in Transcatheter Closure of Sinus Venosus Defects

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Transcatheter closure (TCC) of sinus venosus defects (SVD) using balloon‐expandable covered stents is an emerging alternative to surgery. ZephyrCS (Sahajanand Laser Technologies, Gandhinagar, India) is available in long lengths to suit SVD closure.

Degree of Hypoxia and Physiological Differences Between Fast and Slow Ascents to Very High Altitude

Oxygen
Introduction: Rapid ascent to altitudes of over 5000 m above sea level are associated with dramatic changes in adaptive physiology. The effects of a gradual ascent on symptoms, oximetry, and heart rate are described and compared with the effects of a ...

Revisiting the concept that interictal implies asymptomatic: Pulse wave amplitude drops uncover autonomic responses during generalized paroxysmal fast activities

Epilepsia, EarlyView.
Abstract Objective Interictal electroencephalographic (EEG) activities are generally considered asymptomatic. Pulse wave amplitude drop (PWAD) is a marker of autonomic nervous system (ANS) reactivity linked to cardiovascular risk. Generalized paroxysmal fast activity (GPFA) is a major EEG pattern in different epileptic conditions.
