Effect of silver colloid dressing over conventional dressings in diabetic foot ulcer: A prospective study.

Objectives: Topical silver treatments and silver dressings are increasingly being utilized for the local treatment of wounds; nevertheless, the evidence for their usefulness is unclear. The aim of this study was to investigate the impact of conventional dressings and silver colloid dressing on diabetic foot ulcers (DFU) with and without compression therapy.

Material And Methods: This prospective, double-blind experiment included 50 patients with non-ischemic DFUs, split into two groups of 25 patients each.

A Randomized Controlled Trial Evaluating Postoperative Port Site Infections Among Patients Undergoing Laparoscopic Cholecystectomy Either via Umbilical or Epigastric Port.

Background And Objectives:  Laparoscopic cholecystectomy (LC) is a keyhole surgical procedure considered a gold standard treatment for benign gallbladder (GB) diseases. GB retrieval is done per the surgeon's choice through an umbilical or epigastric port. However, postoperative port site infection (PSI) and pain were major complications of this technique.

Salinity Gradient-Induced Power Generation in Nanochannels: The Role of pH-Sensitive Polyelectrolyte Layers.

By varying the pH values (pH) and types of salt solution, we investigate the salinity gradient-induced electrical and mechanical flow energies inside a reservoir-connected charged nanochannel with a grafted pH-sensitive polyelectrolyte layer (PEL) on the inner surfaces. The aqueous solutions of KCl, LiCl, BaCl, BeCl, AlCl, and Co(en)Cl salts are used as the working fluid in the current investigation. We examine the associated ionic transport and flow field, aiming to understand the underlying physics behind the generation of electrical and hydraulic energy through alterations in pH and types of salt solution.
