first row transition metal complexes of phthalocyanine are employed as catalysts for the oxidation of cyclohexene and cyclooctene using iodosylbenzene and pentafluoroiodosyl benzene. the catalysis was performed in dichloromethane: methanol:water (80:18:2) solvent mixture.  the products of the catalysis for cyclohexene are epoxycyclohexane, 2-cyclohexene-1-ol and 2-cyclohexene-1-one whereas for ...

Experimental work pertaining to the molecular cytogenetics of malaria vector species of mosquitoes by the application of PCR technique has been carried out. The main objectives of the study included the sequence characterization of nuclear rDNA internal transcribed spacers 1 and 2 (ITS1, ITS2) and mitochondrial DNA COII gene as potential molecular markers for studying genetic relatedness and ph...

Static and dynamic magnetic properties of the tetracoordinate CoII complex [Co(CH3-im)2Cl2], (1, CH3-im = N-methyl-imidazole), studied using thorough analyses of magnetometry, and High-Frequency and -Field EPR (HFEPR) measurements, are reported. The study was supported by ab initio complete active space self-consistent field (CASSCF) calculations. It has been revealed that 1 possesses a large m...

The title compound, [Co(C11H8O5)(C8H7N3)] n , which is based on (E)-3-[3-(carb-oxy-meth-oxy)phen-yl]acrylic acid (H2L) and 3-(pyridin-4-yl)pyrazole (pp) ligands, has been synthesized under solvothermal conditions. The dihedral angle between pyrazole and pyridine rings in the pp ligands is 23.1 (2)°. In the crystal, helical chains formed by pp and L ligands connected to the CoII atom propagate p...

The evolution of fungus-growing termites is supposed to have started in the African rain forests with multiple invasions of semi-arid habitats as well as multiple invasions of the Oriental region. We used sequences of the mitochondrial COII gene and Bayesian dating to investigate the time frame of the evolution of Macrotermes, an important genus of fungus-growing termites. We found that the gen...

Cytochrome c oxidase subunit II (COII), encoded by the mitochondrial genome, exhibits one of the most heterogeneous rates of amino acid replacement among placental mammals. Moreover, it has been demonstrated that cytochrome c oxidase has undergone a structural change in higher primates which has altered its physical interaction with cytochrome c. We collected a large data set of COII sequences ...

An octahedral cobalt(III) complex, trans-[(Me2bpb)Co(bzlan)2]ClO4 (1), with H2Me2bpb = N,N’-(4,5-dimethyl-1,2-phenylene)dipicolinamide and bzlan = benzylamine, has been synthesized and characterized by elemental analyses, IR, UV-Vis, and 1H NMR spectroscopy. The structure of this complex has been determined by X-ray crystallography. The Me2bpb2– is a di-anionic tetradentate ligand furnishing a ...

The design of advanced metal–organic framework (MOF) catalysts for solar-driven conversion CO2 into syngas (CO/H2 mixture) is beneficial. Herein, the a joint MOF heterostructure consisting orderly assembled CoII- and CoIII-based Prussian blue analogs (PBAs) driven by their spontaneous lattice match in growth process reported. As-prepared H/CoIII[email protected]II-PBA cage mesocrystal exhibits ...

b a ckground: anoph eles culicifacies, a major malarial vector has been recognized as a complex of five sibling species, a, b, c, d and e. these sibling species exhibit varied vectorial capacity, host specificity and susceptibility to malarial parasites/ insecticides. in this study, a pcr assay developed earlier for distinguishing the five individual species was validated on samples of a n . cu...
