This paper investigates the mixing of the graphene (GR) particles in the polyester (PE) resin by using two different dispersion techniques which are mechanical stirring and sonication method. This paper shows that the mixing method has a significant effect on the corrosive behavior of the coatings. Fourier Transform Infrared Spectroscopy (FT-IR) characterization technique is done to analyze...

OBJECTIVE To evaluate the endoscopic dilatation of benign esophageal strictures and its outcome. METHODS A prospective descriptive study was conducted at Surgical Unit 4 of Civil Hospital Karachi, over a period of 24 months, from August 2006 to July 2008. Twenty seven patients with benign esophageal strictures underwent esophageal dilatation under fluoroscopic guidance using Savary Gilliard D...

INTRODUCTION Potentially catastrophic presentations and lifelong complications resulting from corrosive ingestions in humans is one of the most challenging situations encountered in clinical medical practice. This study reviewed pattern, mechanisms and associated socio-medical challenges with ingestion of corrosive agents as seen in a tertiary health institution in South-western Nigeria. METH...

Ingested corrosive agents produce oropharyngeal and gastro-oesophageal injuries ranging from minor burns to severe necrosis, depending on the agent, amount, concentration and duration of exposure. A 10-year (1990-1999) study of 23 corrosive oesophagitis patients depicting the clinical spectrums and implications was done. There were 17 (74%) males and 6 (26%) females, with an average age of 16 y...

Currently, the most promising approach in the corrosion protection of smart coatings is the use of nanoreservoirs loaded with corrosion inhibitors. Nanocontainers are filled with anti-corrosive agents and are embedded into a primer coating. Future prospective containers are halloysite nanotubes (HNTs) due to their low price, availability, durability, with high mechanical strength and biocompati...

INTRODUCTION Acute intoxications with corrosive substances can cause severe chemical injuries of the upper gastrointestinal tract, most often located in the mouth, pharynx, esophagus, stomach and duodenum. If a patient survives the acute phase of intoxication, regenerative response may result in esophageal and/or gastric stenosis, and increased risk of esophageal and gastric cancer. Such intoxi...

Corrosive esophageal burn is a common health problem in the pediatric age group and causes serious esophageal injuries. The medical treatment in acute phase of corrosive esophageal injury is of particular importance for prevention of esophageal stricture. We therefore aimed to investigate the possible beneficial effect of trapidil (triazolopyrimidine), an inhibitor for phosphodiesterase and pla...
