materials and methods in this study, 90 patients with second-degree burn injuries who were admitted to the yazd burn hospital were randomly divided into three equal groups. in the negative control group, the wounds were covered with sterile vaseline gauze followed by double sterile dry gauze and ultimately bandaged. in the test group, the wounds were covered by an iranian hydrogel sheet (irgel)...

Seven buffer and gel systems for polyacrylamide gel electrophoresis using discontinuous voltage and pH gradients (disc electrophoresis according to ORNSTEIN-UAVIS) and five systems using discontinuous voltage gradients at constant pH (according to ALLEN) have been compiled and characterized. Usefulness and applicability of the systems for clinical investigations are discussed and illustrated by...

RNA-based applications requiring high-quality, non-degraded RNA are a foundational element of many research studies. As such, it is paramount that the integrity of experimental RNA is validated prior to cDNA synthesis or other downstream applications. In the absence of expensive equipment such as microfluidic electrophoretic devices, and as an alternative to the costly and time-consuming standa...

In this paper, carbon nanotubes (CNTs) were added into chitosan (CS) hydrogels in the form of chitosan modified CNTs (CS-CNTs) composites to prepare carbon nanotubes hydrogels (CNTs-GEL). The products, named CS-MWCNTs, were characterized by scanning electron microscope (SEM) and Fourier transform infrared (FTIR) spectroscopy. Swelling properties and effect of pH on controlled release performanc...

Bigels are unique two-phase systems that have recently been presented as a structured method for active ingredient application. The purposes of the current study were to develop and characterize bigel formulations containing loxoprofen. They benefits both hydrogel organo-gel. In order enhance penetration, pluronic lecithin was added form organo-gel, HPMC hydrogel, which properly hydrates stratu...

Pulsed field gel electrophoresis (PFGE) is capable of resolving large DNA molecules of up to two million nucleotides and is becoming a widely used technique in DNA studies (1—3). Three factors can potentially limit PFGE in a laboratory: 1. the cost of the apparatus, 2. reproducibility of electrophoretic conditions, and 3. unusually long electrophoretic time. To alleviate some of these problems ...

This protocol describes a method for in-gel digestion of proteins after fractionation using SDS-PAGE. It is applicable to both oneand two-dimensional polyacrylamide gels of different thicknesses, acrylamide concentrations, and band (spot) sizes. This protocol followed by liquid chromatography/mass spectrometry/mass spectrometry (LC-MS/MS) or matrix-assisted laser desorption/ionization/time of f...
