Molecular dynamics simulations were conducted to evaluate the effect of water desaturation on ion and density distributions diffusion properties in a clay mineral mesopore. Simulations carried out using polarizable model (PIM) force field. Desaturation pore was responsible for significant changes localization mobility molecules ions, especially most unsaturated conditions, which charge overcomp...

OBJECTIVE It has been suggested that oxidative stress and inflammation are associated with the pathophysiology of sleep disorders in end-stage renal disease (ESRD) patients. We examined the relationship of the sleep variables reflecting sleep breathing disorder and limb movements during sleep with the clinical variables reflecting the metabolic abnormalities in ESRD patients receiving hemodialy...

BACKGROUND Lipomas are common benign tumors, but they rarely occur in the retropharyngeal space and even more rarely occur in children. CASE REPORT We report the case of an 11-year-old girl with a 5-year history of progressively worsening nasal obstruction, snoring, and excessive daytime sleepiness. Physical examination revealed a child with a body mass index of 16.9 kg/m2; otolaryngologic ex...

Introduction The craniofacial abnormalities found in infants with cleft palate (CP) decrease their airway patency and increase risk of obstructive sleep apnoea (OSA). We hypothesise that optimising position CP may improve offer a ‘low-cost, high-impact’ intervention to prevent the negative impacts OSA. Because centres give inconsistent advice about position: some recommend back-lying others sid...

OBJECTIVE Infants who sleep prone and face down on soft bedding are particularly vulnerable for sudden infant death syndrome. It has been suggested that 1 mechanism of death in this situation involves rebreathing of expired air. Many infants tolerate rebreathing while lying prone face down for long periods with stable saturations. Others occasionally have rapid desaturations and may require int...

In the application of vehicle power supply and distributed power generation, there are strict requirements for the pulse width modulation (PWM) converter regarding power density and reliability. When compared with the conventional insulated gate bipolar transistor (IGBT) module, the Reverse Conducting-Insulated Gate Bipolar Transistor (RC-IGBT) with the same package has a lower thermal resistan...

Desaturation of [1-r4C]stearic acid, [lJ4C]palmitic acid, and [l-14C]stearoyl-CoA was measured in homogenates of lo-day-old rat brain. Desaturation was maximal with stearoyl-CoA at pH 6.0 to 6.6. With free fatty acids, monoene formation was maximal at pH 7.2 to 7.6; stearic acid was more actively desaturated than palmitic acid. Activity with stearic acid or stearoyl-CoA was linear with protein ...

Background: With the goal of optimizing tissue perfusion and maintaining adequate oxygen delivery, nurses play an important role in monitoring oxygenation and ventilation. Nursing practices may affect oxygen saturation in critically ill patients. Aim of study was to determine the relationship between nursing practices and oxygen desaturation in critically ill patients. Design: A descriptive res...

INTRODUCTION The clinical importance of postoperative episodic hypoxemia is still unclear, and therefore largely under-studied. As a result, there is limited understanding of its relationship with early postoperative respiratory complications (PRC, defined as intubation within three days of surgery) and hospital resource utilization. MATERIALS AND METHODS This single center study was performe...

BACKGROUND Sleepiness-at-the-wheel has been identified as a major cause of highway accidents. The aim of our study is identifying the candidate measures for home-based screening of sleep disordered breathing in Taiwanese bus drivers, instead of polysomnography. METHODS Overnight polysomnography accompanied with simultaneous measurements of alternative screening devices (pulse oximetry, ApneaL...
