black zira (bunium persicum) is a medicinal plant and spice, naturally grows in iran. the aim of this study was to investigate the combined effects of different concentrations of bunium persicum essential oil (eo; including 0, 0.08, 0.16 and 0.24%), three incubation temperatures (15, 25 and 35˚c), three levels of ph (5, 6 and 7 adjusted by hydrochloric acid), and three inoculum size (102, 103 a...

In this paper, capillary zone electrophoresis method was used for the determination of vitamin C and nicotinic acid content in black bean. 20 mmol/L borax solution and 20% acetonitrile concentration, 20kV voltage, 254 nm UV detection wavelength was chosen for electrophoretic analysis. Measured vitamin C and nicotinic acid content in black bean were 0.333 mg/g (RSD = 3.9%) (n = 5), 0.482 mg/g (R...

the concentrations of some heavy metals in sediment from the sinop coasts of the black sea were measured to monitor metal pollution in 2013. the distribution of the heavy metals in sediments of the black sea shows a variable pattern. the objectives of the present study were to elucidate the distribution heavy metals such as cu, pb, zn, ni, mn, fe, as, cd, cr, hg and co in sediment from sinop co...

the effect of salting by different salt composition on fatty acid profile studied in hot smoked black and caspian sea sprat, clupeonella cultriventris. after initial prepare activities, samples were exposed to brining process within two salt concentrations including of 100 % nacl (treatment 1 or t1) and 75 % nacl- 25 % kcl (treatment 2 or t2) under 15% brine solution for 3 hrs. the smoking proc...

Kojic acid functions as an antioxidant in cosmetic products. Kojic acid was not a toxicant in acute, chronic, reproductive, and genotoxicity studies. While some animal data suggested tumor promotion and weak carcinogenicity, kojic acid is slowly absorbed into the circulation from human skin and likely would not reach the threshold at which these effects were seen. The available human sensitizat...

A lysosomal storage disease with accumulation of periodic acid-Schiff- and Sudan black-positive autofluorescent granules in neurons occurred in one 5 1/2- and one 7-year-old dachshund. Ultrastructurally, the storage material consisted of membranous material arranged in stacks and fingerprint patterns. The disease was defined as ceroid-lipofuscinosis, and resembled a previously reported case in ...

Bacillus halodurans MTCC 865 was employed for decolorization of textile azo dye, Acid Black-24 (AB-24). Thousand mgl⁻¹ of AB-24 was decolorized with 90% efficiency by the strain within 6 hrs at pH 9 and 37 °C with 5% NaCl under static conditions in screening medium. Decolorization was evaluated by measuring the periodic decrease in absorbance at 557 nm (λ(max)). Biodegradation of Acid Black-24 ...

Black tea is one of the world's most popular beverages, and its health-promoting effects have been intensively investigated. The antiobesity and hypolipidemic effects of black tea have attracted increasing interest, but the mechanisms underlying these phenomena remain unclear. In the present study, the black tea major component theaflavins were assessed for their hepatic lipid-lowering potentia...
