INTRODUCTION The present study is a pilot prospective safety evaluation of a new closed loop computerised protocol on ventilation and oxygenation in stable, spontaneously breathing children weighing more than 7 kg, during the weaning phase of mechanical ventilation. METHODS Mechanically ventilated children ready to start the weaning process were ventilated for five periods of 60 minutes in th...

BACKGROUND Adaptive support ventilation (ASV) facilitates ventilator liberation in postoperative patients in surgical intensive care units (ICU). Whether ASV has similar benefits in patients with acute respiratory failure is unclear. METHODS We conducted a pilot study in a medical ICU that manages approximately 600 mechanically ventilated patients a year. The ICU has one respiratory therapist...

Several mammalian enzymes catalyzing the phosphorolytic-arsenolytic cleavage of their substrates (thus yielding arsenylated metabolites) have been shown to facilitate reduction of arsenate (AsV) to the more toxic arsenite (AsIII) in presence of their substrate and a thiol. These include purine nucleoside phosphorylase (PNP), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), and glycogen phospho...

The environmentally prevalent arsenate (AsV) is reduced in the body to the much more toxic arsenite (AsIII). Recently, we have demonstrated that the glycolytic enzyme glyceraldehyde-3-phosphate dehydrogenase (GAPDH) catalyzes the reduction of AsV in the presence of glutathione, yet the role of GAPDH in AsV reduction in vivo is unknown. Therefore, we examined the effect of (S)-alpha-cholorhydrin...

BACKGROUND AND PURPOSE Understanding the anatomy of the anterior septal vein (ASV) is critical for minimally invasive procedures to the third ventricle and for assessing lesion size and venous drainage in the anterior cranial fossa. Accordingly, this study evaluated topographic anatomy and anatomic variation of the ASV using susceptibility-weighted imaging (SWI). METHODS Sixty volunteers were...

OBJECTIVES The aim of this study was to investigate whether effective suppression of central sleep apnea (CSA) by adaptive servo-ventilation (ASV) improves underlying cardiac dysfunction among patients with heart failure (HF) in whom CSA was not effectively suppressed by continuous positive airway pressure (CPAP). BACKGROUND The presence of CSA in HF is associated with a poor prognosis, where...

The mammalian enzymes responsible for reduction of the environmentally prevalent arsenate (AsV) to the much more toxic arsenite (AsIII) are unknown. In the previous paper (Nemeti and Gregus, 2005), we proposed that glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and/or phosphoglycerate kinase (PGK) may catalyze reduction of AsV in human red blood cells (RBC), hemolysate, or rat liver cytosol. ...

Pups were inoculated by varIOUS routes with adeno-associated satellite virus (ASV) of canine origin, either alone or accompanied by infectious canine hepatitis virus (ICHV). ASV was not recovered from the pups inoculated with ASV alone; however, it was recovered from one of the 5 pups inoculated simultaneously with ASV and ICHV that died on the 4th day after inoculation and showed a fever and n...

Adaptive servo-ventilation (ASV) is a form of non-invasive positive airway pressure (PAP) therapy that differs from other PAP devices. It includes features to overcome both obstructive and central sleep-disordered breathing (SDB) events. In the Treatment of Sleep-Disordered Breathing with Predominant Central Sleep Apnea by Adaptive Servo-Ventilation in Patients with Heart Failure (SERVE-HF) stu...

OBJECTIVE We attempted to reveal the changes of the human telomerase reverse transcriptase (hTERT) alternative splicing pattern in gastric carcinogenesis. METHODS Three alternative splicing sites (alpha, beta, gamma) were selected and designed PCR primer. The expression of 8 hTERT alternative splicing variants (ASVs) in normal gastric mucosa, precancerous lesions and gastric cancer were detec...
