We report the derivation and characterization of two new human embryonic stem cells (hESC) lines (CU1 and CU2) from embryos with an irreversible loss of integrated organismic function. In addition, we analyzed retrospective data of morphological progression from embryonic day (ED) 5 to ED6 for 2480 embryos not suitable for clinical use to assess grading(More)
OBJECTIVE To determine the effect of early enteral feeding on the outcome of critically ill medical patients whose hemodynamic condition is unstable. METHODS Prospectively collected data in a multi-institutional medical intensive care unit database were analyzed retrospectively. A total of 1174 patients were identified who required mechanical ventilation(More)
BACKGROUND In Muslim countries, end-of-life practices in Muslim brain-dead patients are unknown. We conducted this study to evaluate this issue. RESULTS We identified 42 brain-dead patients between 2001 and 2011. The expectant terminal extubation occurred only in 5. Largely due to family opposition, 2 patients remained "full code," and rests were "do not(More)
With recent technological advancements, an increasing number of minimally invasive approaches are being explored as potential alternatives to the traditional cut-and-sew Cox maze III for treating atrial fibrillation. We describe an approach for treating atrial fibrillation that consists of a warm beating heart, robotic endoscopic Cox-cryomaze with a full(More)
STUDY OBJECTIVE To evaluate effects of CPAP on pain sensitivity in severe OSA patients. DESIGN Within-subject treatment study. SETTING Hospital-based sleep disorders center. PATIENTS Twelve severe OSA patients (7 men, 5 women), 50.2 ± 12.5 years, with no pain. INTERVENTIONS The morning after a diagnostic nocturnal polysomnogram (NPSG), patients(More)
BACKGROUND "Zero" central line-associated bloodstream infections (CLABSI) have not been reported from Asian countries, which usually have predominance of difficult to curtail gram negative infections. It also remains unclear whether lowering CLABSI rates below National Healthcare Safety Network (NHSN) benchmarks in such countries is even possible. In this(More)
The paper presents an overview of Si MOSFET, SiGe HBT, and InP HBT device and circuit performance for broadband and tuned millimeter-wave applications. Implementations of CMOS-only, SiGe-HBT-only, SiGe BiCMOS, and InP-HBT 30-80 Gb/s high-speed circuit in production 130-nm SiGe BiCMOS and InP HBT technologies are compared.
BACKGROUND Pressure-support ventilation (PSV) is more comfortable than volume controlled-continuous mandatory ventilation (VC-CMV) in acute hypercapnic respiratory failure, in patients undergoing noninvasive ventilation. Physiologic measurements of patient status have been compared in PSV and VC-CMV in endotracheally intubated patients, but patient(More)
This paper presents an analysis of sub-2.5-V topologies and design methodologies for SiGe BiCMOS and sub-90nm CMOS building blocks to be used in the next generation of 40-100 Gb/s wireline transceivers. Examples of optimal designs for 40-80Gb/s broadband low-noise input comparators, low-voltage high-speed MOS- and BiCMOS CML logic gates, 30-100 GHz(More)
BACKGROUND American Thoracic Society (ATS) guidelines for methacholine challenge testing (MCT) discuss specific airways conductance (sG(aw)) as a surrogate marker for forced expiratory volume in the first second (FEV(1)) to diagnose airways obstruction. The guidelines suggest a cutoff value of 45% drop in sG(aw) to diagnose a positive MCT. However, there is(More)
