The basic aim of the present research work is to deliver the diloxanide furoate (DF) at specific area using pectin microspheres. The microspheres were prepared by spray drying method and cross-linked by zinc acetate. Different concentrations of polymer (pectin 0.5–3%) and cross-linking agent (0...

Methyl 2-methyl-3-furoate was subjected to bromination with N-bromosuccinimide (NBS), a milder brominating reagent, under different reaction conditions to obtain a variety of selective brominated products.

Chitosan is non-toxic, biocompatible and biodegradable polysaccharide composed of glucosamine and derived by deacetylation of chitin. Chitosan thermosensitive hydrogel has been developed to form a gel in situ, precluding the need for surgical implantation. In this review, the recent advances in ...

The ultra-high molecular weight polyethylene (UHMWPE) and metal artificial joint pair is limited by wear debris and short service life. Here we report the development of a hydrogel which exhibits lubricant release to intensify the lubrication effect of artificial joints.This study adopted an inj...

The artificial joints would go through serious wear after implantation surgery due to the poor lubrication of the body fluid, and the biomimetic lubricants directly injected in vitro is easy to be absorbed by human tissues, and after a period of time, it will lose its lubrication effect. However...

In this paper the properties of thermosensitive chitosan hydrogels, formulated with chitosan chloride with β-glycerophosphate disodium salt hydrate and chitosan chloride with β-glycerophosphate disodium salt hydrate enriched with calcium glycerophosphate, are presented. The study focused on th...

Publisher SummaryThis chapter discusses the isolation, physical and chemical properties, and synthesis of choline. Choline is widely distributed in biological materials as free choline, acetylcholine, and more complex phospholipids and their metabolic intermediates. Choline is characterized by a...

The uptake of methyl-14C-methionine by schistosomula, 21 day-old and adult Schistosoma mansoni in vitro has been investigated. Ligation of the adult pharynx and comparison between the kinetics of uptake of schistosomula and adults suggests that methionine is absorbed, in the system described, pr...

ObjectiveThe relevance of oxidative stress in mice fed a choline-deficient diet (CDD) was investigated in relation to the oxidative stress marker, hydroxyoctadecadienoic acid (HODE) in comparison with F2-isoprostanes. Further, the protective effects of antioxidants against oxidative damage were ...

We examined the functional characteristics of choline uptake in human tongue carcinoma using the cell line HSC-3. Furthermore, we explored the possible correlation between the inhibition of choline uptake and apoptotic cell death. Both choline transporter-like protein 1 (CTL1) and CTL2 mRNAs and...

The presence of nitric oxide NO in the gas phase was shown to decrease the decomposition rate of the hydrotalcite-like Co–Al LDH phase in the catalysts prepared by co-precipitation or deposition on Al2O3 under the condition of urea hydrolysis. The decrease in LDH decomposition rate is related t...

The present work is focused on the cobalt electrodeposition in anodic aluminium oxide and the application of the obtained nanocomposite layer as a monolithic catalyst for complete methane oxidation. For the investigation of cobalt nanowires growing in the pores of nanoporous alumina template, cy...

The oxidation of thiols in petroleum is a subject of ongoing research, discussion and removal of sulfur is a topic of ongoing legislation. The Merox® process requires high pressures and temperatures. Novel catalysts and methods innovations are of interest. This work examines the synthesis, purif...

Cobalt oxide nanostructures have been considered as promising electrode materials for various electrochemical applications, especially for batteries, supercapacitors, and electrocatalysis, owing to their unparalleled advantages of high theoretical capacity, highly-active catalytic properties, an...

Among different strategies, water splitting toward hydrogen production is a promising process to store energy from intermittent sources. However, the anodic water oxidation is a bottleneck for water splitting. In this paper, we report an aluminum/cobalt/iron/nickel alloy as a precatalyst for the...

Aluminum cobalt oxide-coated LiNi0.5Mn1.5O4 (LNMO) cathode materials are synthesized via a wet-coating method. The surface coating of the LNMO with cobalt aluminum oxide (CoAl2O4) does not alter its spinel structure, but greatly affects its thermostability. The complete, thin cobalt aluminum oxi...

Conducting polymer polypyrrole is promising material for electronic devices and sensor applications. To enhance its properties ternary compound Cobalt Aluminum Oxide (CAO) Nano powder in different weight percent were added. In presence of oxidizing agent ammonium persulphate CAO/polypyrrole Nano...

Black carbon is often used as an indicator for combustion-related air pollution. In urban environments, on-road black carbon concentrations have a large spatial variability, suggesting that the personal exposure of a cyclist to black carbon can heavily depend on the route that is chosen to reach...

The paper assesses evidence concerning the effects of transportation's black carbon emissions on climate change, public health, and food production; and it discusses policy issues posed by the emissions. Black carbon emission mitigation policies at all levels offer significant potential cli...

Dual-filler systems may promote synergetic effects to mechanical properties in rubber compounds. The use of metakaolin (M) and carbon black (C) in nitrile rubber (NBR) compounds was studied with respect to rheological and non-obvious mechanical tests. The reaction order of the curing process was...
