Vapour-Phase Selective Hydrogenation of γ-Valerolactone to 2-Methyltetrahydrofuran Biofuel over Silica-Supported Copper Catalysts.

2-Methyltetrahydrofuran (MTHF) is a desirable biomass-based platform chemical with excellent potential as an ideal biofuel, green solvent, and raw material for synthesizing downstream chemicals. In this work, a series of copper nanoparticles encapsulated on SiO were prepared by the wet impregnation method and evaluated as efficient non-noble metal catalysts for the vapour-phase hydrogenation of γ-valerolactone (GVL) to MTHF in a fixed-bed reactor under mild reaction conditions. The obtained catalyst properties were determined by XRD, FE-SEM, TEM, UV-DRS, TPR, NH-TPD, NO decomposition and pore size distribution measurements.

External phallopexy: A revisited technique and algorithm for simple management of buried penis.

Introduction: Buried penis (BP) is a distressing condition for both the child and his caregivers. A lot of techniques are available for the management of such condition. External phallopexy represents a simple technique designed for selected cases.

Ventrally Fused Conjoined Twins (Omphaloischiopagus): A Roadmap to Successful Separation.

Conjoined twining is one of the most fascinating and challenging situations which a pediatric surgeon may face in his career. Only few surgeons may have the opportunity to share in separation of such cases. In this report, we aim to share our experience with the successful separation of ventrally fused male conjoined twins (omphaloischiopagus).

Superior Non-Invasive Glucose Sensor Using Bimetallic CuNi Nanospecies Coated Mesoporous Carbon.

The assessment of blood glucose levels is necessary for the diagnosis and management of diabetes. The accurate quantification of serum or plasma glucose relies on enzymatic and nonenzymatic methods utilizing electrochemical biosensors. Current research efforts are focused on enhancing the non-invasive detection of glucose in sweat with accuracy, high sensitivity, and stability.

Needlescopic Disconnection and Peritoneal Closure for Pediatric Inguinal Hernia Repair: A Novel Technique.

Background: There are many laparoscopic techniques for pediatric congenital inguinal hernia repair. Needlescopic surgery was introduced recently in pediatric patients aiming at getting excellent cosmetic outcomes.

Purpose: The aim of this study was to describe a novel technique for needlescopic inguinal hernia repair in children.

An efficient green ionic liquid for the corrosion inhibition of reinforcement steel in neutral and alkaline highly saline simulated concrete pore solutions.

The effect of the green ionic liquid compound, Quaternium-32 (Q-32), on the corrosion inhibition performance of reinforcement steel, in a simulated concrete pore solution, was investigated at different temperatures and pH values, using electrochemical impedance spectroscopy (EIS). The inhibition efficiency was improved as the concentration of Q-32 and pH values were increased. However, it decreased as the temperature was raised.

Can botulinum toxin help in managing children with functional constipation and obstructed defecation?

Background: Functional constipation (FC) is a common pediatric healthcare problem worldwide. Obstructed defection syndrome (ODS) is frequently presented with an inability to coordinate the bowel movement with pelvic floor muscles. Botulinum toxin (BT) intraanal sphincteric injection can improve the obstructed defecation by relaxing the anal sphincter and reducing the required force to propel the stools.

Histopathological perspective of the pulled-through colon in Hirschsprung disease: Impact on clinical outcome.

Background: The outcome in HD has not been always satisfactory even after a technically sound operation.

Purpose: To define the characteristic histopathological features of the pulled-through colon in patients with HD, and it is impact on clinical outcome.

Patients And Methods: The study included patients with HD who underwent surgical repair between 2010 through 2016.

Colonic replacement of the esophagus: towards standardization of the technique.

Since we have started colonic replacement of the esophagus in children, several successive modifications have led to evolution of the surgical technique aiming to decrease complications and achieve the best functional outcome. Currently, our surgical group has reached a single standardized technique that has been applied to all cases included in this report. A colonic flap (including the transverse colon) is prepared based on the left colic vessels.

Anatomical alterations following the 'PSARP' procedure: Correlating MRI findings with continence scores.

Purpose: To identify anatomical aberrations following PSARP procedure by using MRI, while correlating MRI findings to clinical outcome.

Patients And Methods: Between January 2014 and December 2017, we conducted our study on male patients with rectourethral fistula who underwent PSARP. Postoperative pelvic MRI studies were performed and correlated to their clinical continence scores (Rintala, and Krickenbeck classification).

The Currarino triad: What pediatric surgeons need to know.

Purpose: We report our experience in managing a group of patients with Currarino syndrome, highlighting diagnostic challenges, surgical techniques, in addition to a review of current neurosurgical options.

Patients And Methods: The study included patients with Currarino syndrome who presented to our pediatric surgery department during the period 2010 through 2016. The 'sacral scimitar' in plain X-ray provided the clue for the diagnosis; while MRI examination was essential to define the nature of the presacral mass and associated spinal anomalies.

The radiological assessment of colonic replacement of the esophagus in children: A review of 43 cases.

Purpose: To define the characteristic radiological features following colonic replacement of the esophagus in children.

Materials And Methods: The upper gastro-intestinal contrast studies of 43 patients who underwent colonic replacement of the esophagus at our pediatric surgery unit were available for analysis. UGI contrast studies were performed routinely in the post-surgical period in 17 cases (first asymptomatic group), while the rest of contrast studies (26) belonged to a second group of out-patients complaining of dysphagia (18) or dyspepsia (8) following colonic replacement of the esophagus.

Contrast enema as a guide for senna-based laxatives in managing overflow retentive stool incontinence in pediatrics.

Objectives: Overflow retentive stool incontinence (ORSI) is secondary to constipation and fecal loading. In our study, the dose and duration of senna-based laxatives (SBL) treatment to achieve full defecatory control will be examined for possible correlation with new parameters measured from the initial contrast enema.

Methods: Initially, an observational study was conducted prospectively on a group of patient with ORSI to define the optimum dose of SBL to achieve full defecatory control with measurement of six parameters in the initial contrast enema (level of colonic dilatation, recto-anal angle, ratio of maximal diameter of dilated colon to last lumbar spine, ratio of maximum diameter of dilated colon to normal descending colon, immediate and after 24-h post-evacuation residual contrast).
