The synergistic combination of layer-by-layer (LbL) assembly and nanoporous membrane templating has greatly facilitated the creation of complex and functional nanotubular structures. The approach takes advantage of both the new properties conferred by assembling diverse LbL building blocks and the tight dimensional control offered by nanotemplating to enable new functionalities that arise from ...

AIM To assess the impact of laparoscopic liver resection (LLR) on surgical blood loss (SBL), especially in patients with antithrombotics for thromboembolic risks. METHODS Consecutive 258 patients receiving liver resection at our institution between 2010 and 2016 were retrospectively reviewed. Preoperative antithrombotic therapy (ATT; antiplatelets and/or anticoagulation) was regularly used in...

BACKGROUND There are limited data on the safety of colonoscopy in patients with lower gastrointestinal bleeding (LGIB). We examined the various adverse events associated with colonoscopy in acute LGIB compared with non-GIB patients. METHODS Emergency hospitalized LGIB patients (n = 161) and age- and gender-matched non-GIB controls (n = 161) were selected. Primary outcomes were any adverse eve...

Abstract Gastrointestinal bleeding (GIB) is one of the most common leading life-threatening conditions requiring prompt diagnosis and rapid endoscopic interventional radiology (IR) management. Endoscopy first line management for upper GIB, while it has a limited role in lower especially acute clinical settings, due to poor bowel preparation. Patients with failed refractory necessitate emergent ...

Sparse Bayesian learning (SBL) is applied to the coprime array for underdetermined wideband direction of arrival (DOA) estimation. Using the augmented covariance matrix, the coprime array can achieve a higher number of degrees of freedom (DOFs) to resolve more sources than the number of physical sensors. The sparse-based DOA estimation can deteriorate the detection and estimation performance be...

INTRODUCTION Gastrointestinal basidiobolomycosis (GIB) is an emerging fungal infection with a few cases reported worldwide. It is caused by Basidiobolus ranarum, which does not usually invade blood vessels and rarely disseminates. CASE PRESENTATION We present a rare case of GIB with hepatic dissemination in a 12-year-old Yemeni boy living in southwestern Saudi Arabia. The initial provisional ...

The use of methanethiosulfonates as thiol-specific modifying reagents in the strategy of combined site-directed mutagenesis and chemical modification allows virtually unlimited opportunities for creating new protein surface environments. As a consequence of our interest in electrostatic manipulation as a means of tailoring enzyme activity and specificity, we have adopted this approach for the c...

A new sensor based homing integrated guidance and control law is presented to drive an underactuated autonomous underwater vehicle (AUV) towards a fixed target, in the horizontal plane, using the information provided by an Ultra-Short Base Line (USBL) positioning system. Almost global asymptotic stability (AGAS) is achieved, both in the absence of external disturbances and in the presence of co...

Background In recent years, tendency to use drugs has been increasing in the treatment of neonatal jaundice. Several drugs have been used since then, but the effect of probiotics on serum bilirubin level (SBL) is not so clear. This study was conducted to evaluate the effect of probiotics on SBL and the duration of phototherapy in term neonates with hyperbilirubinemia. Materials and Methods: In ...

Background The most commonly used treatment for neonatal hyperbilirubinemia (NH) are phototherapy and exchange transfusion. Among the drug therapy for NH less has been paid to the effect of zinc administration on serum bilirubin level (SBL). This study was carried out to determine the on the effect of oral zinc sulfate on the SBL in term neonates with hyperbilirubinemia. Materials and Methods I...
