Graphene oxide-chitosan hydrogel for adsorptive removal of diclofenac from aqueous solution: preparation, characterization, kinetic and thermodynamic modelling.

This work aimed at developing a natural compound-based hydrogel adsorbent to remove diclofenac as a model pharmaceutical from water. First, graphene oxide-chitosan (GO-CTS) and amine graphene oxide-chitosan (AGO-CTS) hydrogel adsorbents were synthesized a facile mechanical mixing method. The synthesized materials were characterized through Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), scanning and transmission electron microscopy (SEM and TEM), Raman spectroscopy, and thermogravimetric analysis (TGA) techniques.

Comparing the effects of hot pack and lukewarm-water-soaked gauze on postoperative urinary retention; a randomized controlled clinical trial.

Background: Urinary retention is a common postoperative complication that mandates urinary catheterization. Urinary catheterization is associated with different physical, mental, and financial problems for both patients and healthcare systems. The patient inconvenience, urinary tract infections, and increase in hospital stay and expenses are common problems of urinary retention and urinary catheterization.

Right laparoscopic donor nephrectomy and the use of inverted kidney transplantation: an alternative technique.

Objectives: To report a novel approach to overcome the problems associated with a short right renal vein harvested by clipping the vein during right laparoscopic donor nephrectomy (RLDN).

Patients And Methods: This prospective study included 32 donors and their recipients; all donors had transperitoneal RLDN. The right renal artery and vein were ligated by Hem-o-lok and titanium clips, which resulted in a very short renal vein (<1.
