study was undertaken to establish the optimum dietary indispensable amino acid (IAA) profile for yellow fin seabream broodstock based on the amino acid (AA) profile of broodstock, eggs and larvae of Acanthopagrus latus. Three isonitrogenous (40%) and isolipid (20%), named diets 1, 2 and 3 were formulated with different ratios of total essential amino acids per total non-essential amino acid...

Throughour screening programofbioactive secondary metabolites of microbial origin, we have isolated a new azaphilone-type metabolite, diazaphilonic acid (Fig. 1). In this paper, we report the taxonomy of the producing strain, production, isolation, physico-chemical properties and biological activities of diazaphilonic acid. The mycological characteristics of the producing fungal strain PF1195 (...

A novel yellow laccase was produced from Lentinus squarrosulus MR13 under solid state fermentation. The yellow laccase was purified by a factor of 12.67-fold by ammonium sulfate precipitation, anion exchange chromatography and gel filtration chromatography to a specific activity of 3,772.86 IU mg-1. Its molecular mass was determined by SDS-PAGE and found to be 66 kDa. The activity of the enzyme...

flaviviridae are viruses that cause several diseases including dengue fever, japanese encephalitis, murray valley encephalitis, tick-borne encephalitis, west nile encephalitis, yellow fever and hepatitis c virus infection. members of this family have monopartite, linear, single-stranded rna genomes of positive polarity, 9.6-12.3 kb in length. here, we have analyzed the codon usage of 13 species...

Brief treatment of Escherichia coli with 2 x 10(-4)m ethylenediaminetetraacetic acid (EDTA)-0.12 m tris(hydroxymethyl)aminomethane (Tris), pH 8.0, or 0.12 m Tris alone resulted in the release of the acid-soluble nucleotide pool at 3 or 23 C. Exposure to EDTA-Tris for up to 90 min at 3 C did not result in the release of increasing amounts of 260-mmu-absorbing material. At 23 and 37 C, EDTA-Tris ...

objective:   the aim of this study was to evaluate the bond strength between metal brackets and non-glazed ceramic with three different surface treatment methods. materials and methods: forty-two non-glazed ceramic disks were assigned into three groups. group i and ii specimens were etched with 9.5% hydrofluoric acid. subsequently in group i, silane and adhesive were applied and in group ii, bo...

Genotypic variation in composition and antioxidant activity was evaluated using 25 cultivars, 5 each of white-flesh nectarines, yellow-flesh nectarines, white-flesh peaches, yellow-flesh peaches, and plums, at the ripe (ready-to-eat) stage. The ranges of total ascorbic acid (vitamin C) (in mg/100 g of fresh weight) were 5-14 (white-flesh nectarines), 6-8 (yellow-flesh nectarines), 6-9 (white-fl...

Gadolinium oxide (Gd2O3) nanoparticles were prepared via the reaction of gadolinium nitrate hexahydrate (Gd (NO3)3·6H2O) and ethylamine (C2H5NH2), their surface morphology, particle size, properties examined by using scanning electron microscopy, X-ray diffraction (XRD), Raman spectroscopy, Fourier transform infrared (FT-IR) ultraviolet visible (UV-vis) spectroscopy. The Gd2O3 used as photocata...

A practical and green method for the synthesis of 5H-dibenzo[b,i]xanthene-tetraones and spiro[dibenzo[b,i]xanthene-13,3'-indoline]-pentaones by the condensation of 2-hydroxynaphthalene-1,4-dione with aldehydes or isatins, respectively, in the presence of a catalytic amount of cellulose sulfuric acid (CSA) under solvent-free conditions at 100 °C is described. The significant features of this pro...
