Introduction: Aluminum is known as a neurotoxic element which causes neurodegeneration, learning deduction and movement disorders. Aluminum ions in the brain cause serious problems such as Alzheimer, Parkinson and other degenerative diseases. On the other hand, Zinc is a dietary element essential for several biological processes, modulates neurotransmission in brain regions and associates wi...

Diabetes mellitus (DM) is a health problem affecting millions of individuals worldwide. Diabetic nephropathy (DN), as a significant complication of DM, has become the most common cause of endstage renal failure. Oxidative stress constitutes the key and common events in the pathogenesis of DN and antioxidants may play a beneficial role in its prevention. This study was conducted to investigate t...

In this work, various 3-cyano-4-aryl-4H-pyran derivatives were prepared efficiently through a one-pot,multicomponent synthesis between aromatic aldehyde, malononitrile and acetophenone derivativesor ethyl acetoacetate using Fe3O4/EDTA magnetic nanocatalyst and ethanol as solvent. The reactionswere completed at room temperature in 10 min using 5 mg of catalyst and 2 mL of solvent to prepare1 mmo...

The dissolution of sugarcane bagasse cellulose (SBC) in zinc chloride solution was studied at elevated temperatures. Based on single factor experiments, the effects of zinc chloride mass fraction, dissolution time, temperature, and bagasse cellulose mass fraction were investigated by an orthogonal experiment, and the optimal dissolution conditions were obtained. The dissolution process of bagas...

Exo-polysaccharides like dextran produced by Weissella sp. have a wide range of applications in the food, pharmaceutical and other industries. This biopolymer and its derivatives like iron dextran, clinical dextran are rapidly emerging as a new and industrially important products. Dextran a polymer of glucose is produced using sucrose rich media with nitrogen source. It also requires efficient ...

Other studies avoided the use of a zinc salt by generating lithium zincates either by iodine-metal exchange 7 or by deprotonation. 8 In 2002, Gauthier and co-workers documented an approach through lithium zincates using only one third equivalent of zinc chloride for the synthesis of 5-aryl-2-furaldehydes from 5-lithio-2-furaldehyde diethyl acetal. 9 In addition, Mutule and Suma described in 200...

Zinc sulphate and boric acid ophthalmic preparations, containing benzalkonium chloride as preservative, have been investigated against gram-negative and positive bacteria. Viability of bacteria was found after 7 days, although it was completely suppressed after 24 hours of inoculation. Zinc sulphate generally increases the antimicrobial activity of benzalkonium chloride, whereas boric acid ...

Mohs melanoma chemosurgery using 50% zinc chloride has not been widely accepted despite a 30-year consecutive series indicating 53% survival improvement (p = .003) for advancedmelanomas over conventional surgery. In chemosurgery, melanomas are fixed and removed in layers with 24-hour zinc chloride paste applications before each excision. An extra application is made to the tumor-free plane to e...
