In this study, the Acid Black 1 dye containing effluent collected from a dyeing unit was examined with the alginate extracted from the marine brown algae, Sargassum sp. for its removal. Batch experiments were carried out using standard Jar test apparatus. Fourier Transform InfraRed (FT-IR) Spectroscopy and Scanning Electron Microscopy (SEM) techniques were used to characterize the raw algin...

The bile acids in brown pigment stones and gall-bladder bile were fractionated into free acids, gly-cine and taurine conjugates, and sulfates, usingdiethylamino-hydroxypropyl-SephadexLH-20 (DEAP-LH-20)column chromatography,and were quantitatedby gas chromatography. Twenty-eight cases of brownpigment stones were studied and divided into twogroups: those wi...

Textile wastewater contains a number of dyes which are known to be toxic and carcinogenic. In this study the results show that the Fenton (Fe2+/H2O2) process is an efficient method for the removal of Acid Brown 14 (A.BR14) and Cationic Blue 41 (C.B41) dyes from textile wastewater. In this method, two reagents Fe2+and H2O2 are used and do not require any additional energy. Several experiment...

Our results show that all of the brown rot fungi tested produce oxalic acid in liquid as well as in semisolid cultures. Gloeophyllum trabeum, which accumulates the lowest amount of oxalic acid during decay of pine holocellulose, showed the highest polysaccharide-depolymerizing activity. Semisolid cultures inoculated with this fungus rapidly converted C-labeled oxalic acid to CO(2) during cellul...

Ascorbic acid and fructose react in an aqueous alkaline solution at temperature below 50°C in a Maillard-type reaction to from brown coloured end products. The kinetics of browning of alkaline solution of fructose in presence of ascorbic acid has been studied by measuring the absorbance of browning development in the reaction. The development of brown colour due to heating of either reducing su...

In this study, a colorimetric discrimination of Pd2+ and Hg2+ ions in the solvent solid film states one silver nanoparticles (AgNPs) sensing system is presented. First, were prepared by reducing AgNO3 with sodium borohydride presence chitosan different organic acids, including acetic acid, propanedioic citric acid. The addition acids allowed for surface plasmon resonance (SPR) intensity size di...

Brown adipose tissue has a central role in thermogenesis to maintain body temperature through energy dissipation in small mammals and has recently been verified to function in adult humans as well. Here, we demonstrate that the heart-type fatty acid-binding protein, FABP3, is essential for cold tolerance and efficient fatty acid oxidation in mouse brown adipose tissue, despite the abundant expr...

The present study is the first to examine the modulation of retinal kynurenic acid (KYNA) content in response to N-methyl-D-aspartate (NMDA)-induced cell death in adult rat retinal ganglion cells (RGC). Adult Brown Norway rats were intravitreally injected with NMDA or PBS. Surviving RGC were retrogradely labeled with fluorogold and counted in wholemounts of retinas 2, 7 and 14 days after inject...

An evaluation of several insecticides, namely, 0.01% fipronil, 0.05% indoxacarb, and 2% boric acid in liquid bait formulations were carried out against field populations of the longlegged ant, Anoplolepis gracilipes (Fr. Smith) (Hymenoptera: Formicidae). The baits were formulated in brown cane sugar solution (50%, wt:wt) and placed in an experimental bait station. Each bait was evaluated agains...
