Oral administration of dimethyldithiocarbamate pesticides (ferbam, ziram or sodium dimethyldithiocarbamate) or thiram together with nickel resulted in increased levels of the metal in several tissues of rats, in comparison with animals given only nickel. In contrast, the administration of nickel...

In this study, ferromagnetic cobalt ferrite (CoFe2O4) fibers were synthesized by electrospinning technique using a DMF/ethanol mixed precursor solution of poly (vinyl pyrrolidone) (PVP) and cobalt and iron (III) nitrates. The as-spun precursor fibers were characterized using thermogravimetric an...

The hydrometallurgical technique, the reduction of oxides, atomization, carbonyl processing, the electrolytic method, the amalgam technique, the ultrasonic spray pyrolysis of cobalt, and cobalt-alloy powder production are discussed in this chapter. The fundamentals of the leaching autoclave proc...

This paper deals with the syntheses and structural characterizations of four new cobalt(III) compounds (1–4) derived from a N3O donor Schiff base ligand and their catalytic activity towards the aerobic oxidation of o-aminophenols. Both counter ions and solvents used for the synthesis have signi...

The copper and cobalt oxides composites coatings on aluminum substrates have been successfully synthesized via sol-gel method using nitrate-based sol precursors. The composites were characterized by X-ray Diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Field Emission Scanning Electron...

Effect of the cobalt precursors, including [Co(bipy)3](NO3)2, [Co(NH3)5Cl]Cl2, [Co(NH3)6]Cl3, and [Co(en)2Cl2] Cl, on reactivity of the cationic Co/SiO2 prepared by strong electrostatic adsorption (SEA) was investigated for the dehydrogenation of cyclohexane as a model reaction. According to the...

A new aroylhydrazone ligand, 2-benzoylpyridine-4-methoxybenzhydrazone (BPMBH) and its two cobalt(III) complexes, [Co(BPMB)2]NO3·1.5H2O (1) and [Co(BPMB)2]Cl·2H2O (2) have been synthesized and structurally characterized. The synthesized compounds are physico-chemically characterized by CHN anal...

The review is focused to discuss the synthetic strategy and properties of mixed valence cobalt(III)/cobalt(II) complexes with N,O-donor Schiff base ligands. Use of compartmental ligand is a good approach to prepare such complexes. Polydentate hydroxy-rich Schiff base ligands have also been used ...

A series of mechanism based heteroaryl urea fatty acid amide hydrolase (FAAH) inhibitors with spirocyclic diamine cores is described. A potent member of this class, (37), was found to inhibit FAAH centrally, elevate the brain levels of three fatty acid ethanolamides [FAAs: anandamide (AEA), oleo...

Notwithstanding the ongoing debate on their full potential in health and disease, there is general consensus that n-3 PUFAs play important physiological roles. Increasing dietary n-3 PUFA intake results in increased DHA and EPA content in cell membranes as well as an increase in n-3 derived oxyl...

The influence of saturated and unsaturated fatty acid ethanolamides as well as Δ9-tetrahydrocannabinol (Δ9-THC), WIN 55,212-2 and cannabinoid CB1 receptor antagonist SR 141716 on sea urchin fertilization was studied. The ethanolamides of arachidonic, oleic and linoleic acids but not saturated ...

The thermal behavior of a series of polybenzoxazines based on aniline and various phenols is examined under both inert and oxidative environments. Under an inert environment, the various phenols substantially affect the char yield of polybenzoxazines without altering the mechanism of Mannich bas...

The present study was attempted to enhance the production of naphthoquinones and phenolics by Fusarium solani PSC-R of Palk Bay origin, which exhibited potent antibacterial, antioxidant and dyeing activity. Maximum productivity of naphthoquinones and phenolics was achieved in potato infusion med...

The naturally occurring 1-O-alkyl-sn-glycerols and their methoxylated congeners, 1-O-(2′-methoxyalkyl)-sn-glycerols, are biologically active compounds, ubiquitously found in nature as diacyl glyceryl ether lipids and phosphoether lipids. The chief objective of this article is to provide a compr...

Suturing is the standard of repair for lacerated flexor tendons. Past studies focused on delivering growth factors to the repair site by incorporating growth factors to nylon sutures which are commonly used in the repair procedure. However, conjugation of growth factors to nylon or other synthet...

Excessive salt (NaCl) intake has been related to several diseases. Small salt crystals that rapidly dissolve in the oral cavity may decrease swallowing of untasted salt. The aim of this research was to evaluate the crystallization of salt as microcrystals by fast water evaporation from droplets ...

Duchenne muscular dystrophy (DMD) is characterized by a progressive loss of muscle fibers, and their substitution by fibrotic and adipose tissue. Many factors contribute to this process, but the molecular pathways related to regeneration and degeneration of muscle are not completely known. Plate...

Marijuana is one of the most marketed illicit drugs in the world. Originated from Cannabis sativa L, Δ9-tetrahydrocannabinol (or Δ9-THC) is proscribed in Brazil by the law number 11.343 from August 23rd of 2006 as well as its isomers, salts, ethers and esters. However, Δ9-THC is the main resp...

Publisher SummaryThere are several forms of carboxamides, and they are separated into three classes: primary, secondary, and tertiary. Primary carboxamides also exist in three forms: H(C=O)NH2, R(C=O)NH2, and ø(C=O)NH2. Secondary carboxamides exist in the forms: H(C=O)NHR, R(C=O)NHR’, R(C=O)NHø...

We investigate how the Z-type dynamic approach can be applied to control backward bifurcation phenomena in epidemic models. Because of its rich phenomenology, that includes stationary or oscillatory subcritical persistence of the disease, we consider the SIR model introduced by Zhou & Fan in [No...
