Background: Mosquito species are the most important among the insects; for the reason that they transmit major diseases viz. malaria, dengue, chikungunya, zika, filariasis and various forms of encephalitis; imposing enormous menace to human as well as animals. These diseases cause huge amount of mortality and morbidity across the world. The principal strategy for fighting these diseases is the ...

n !. "fy ?/ atebrin ingestion, but it is usually iceable in the conjunctiva, skin and urine within a week or ten days of beginning the treatment. This delayed manifestation may be the outcome of cumulation in the various tissues coating of the body and the efforts at excretion through the urine when the concentration has reached a certain point. Atebrin is a drug possessing cumulative action an...

Some fragrance components of spices used for cooking are known to have an effect on human behavior. The aim of this investigation was to examine the effect of the essential oils of basil (Ocimum formacitratum L.) leaves, lemongrass (Cymbopogon citrates L.) herbs, ki lemo (Litsea cubeba L.) bark, and laja gowah (Alpinia malaccencis Roxb.) rhizomes on locomotor activity in mice and identify the a...

We report molecular functionalization of the promising manganite nanoparticles La0.67Sr0.33MnO3 (LSMO) for their solubilization in aqueous environments. The functionalization of individual NPs with the biocompatible citrate ligand, as confirmed by Fourier transform infrared (FTIR) spectroscopy, reveals that citrates are covalently attached to the surface of the NPs. UV-VIS spectroscopic studies...

The pH influence on continuous citric acid secretion was investigated in Candida oleophila ATCC 20177 (var.) under NH4 limiting state steady conditions, using glucose. Highest citric acid concentration of 57.8 g/l, citrate/isocitrate ratio of 15.6, space-time yield of 0.96 g/(l x hr) and biomass specific productivity of 0.041 g/(g x hr) were obtained at pH 5 and 60 hrs residence time. Only 22.8...

Systems based on Ce-Zr are used in catalytic converters for their oxygen storage ability. Recently, their application for soot abatement is under investigation. In this paper, preliminary results of the performance of Ce-Zr systems with the addition of K are reported by varying potassium content and calcination temperature. The powder catalysts were prepared by a variant of the citrates route d...
