In this study, the GH and IGF-I of blue gourami (Trichogaster trichopterus) were examined at different temperatures of 23 ο C, 27 ο C and 31 ο C. GH mRNA expression in the pituitary of males and females at various temperatures was examined using RT-PCR. The mean of mRNA levels was higher in the pituitary glands of females maintained in 23 ο C and 27 ο C than in males. However, no significant di...

Synechococcus, C-Phycocyanin, Sulfur Nutrition The cyanobacterium Synechococcus 6301 is able to use a lim ited number o f sulfur compounds as the only source o f sulfur supply such as sulfate, thiosulfate, thioacetic acid, mercaptoacetic acid, thioacetamide, L-cysteine and glutathione. Compounds containg thioether linkages such as methionin or S-methylcysteine and all compounds investigated so ...

in this study, a new adsorbent, silver nanoparticle loaded on activated carbon (ag˗np˗ac) was used for removal of acid yellow199 (ay 199) dye. this novel material was characterized and identified by different techniques such as brunauer, emmett and teller (bet), field emission scanning electron microscopy (fesem), x-ray diffraction (xrd) analysis. unique properties of this adsorbent such as hig...

The kinetics of cellulose hydrolysis under extremely low acid (ELA) conditions (0.07 wt%) and at temperatures >200°C was investigated using batch reactors and bed-shrinking flow-through (BSFT) reactors. The maximum yield of glucose obtained from batch reactor experiments was about 60% for α-cellulose, which occurred at 205 and 220°C. The maximum glucose yields from yellow poplar feedstocks were...

Abstract Dye-containing wastewater has been known as a serious environmental treat. There are many treatment methods, but they not practical in developing countries. In this study, batch adsorption of acid yellow 17 dye from aqueous solution carried out on laboratory scale using activated water hyacinth root powder. The removal efficiency was measured UV-Vis spectrometer. Adsorption experiments...

Colorless when pure, older samples tend to acquire a yellow cast due to the accumulation of oxides of nitrogen. If the solution contains more than 86% nitric acid, it is referred to as fuming nitric acid. Fuming nitric acid is characterized as white fuming nitric acid and red fuming nitric acid, depending on the amount of nitrogen dioxide present. At concentrations above 95% at room temperature...

Complementary DNA fragments for two isoforms of particulate guanylate cyclase C (GC-C) were cloned from the intestine of the European eel (Anguilla anguilla). Both isoforms exhibited higher nucleotide and amino acid sequence homologies to members of the GC-C family from other species than the related guanylate cyclase A or B (GC-A or GC-B) isoforms from the eel. Northern blots indicated that pr...

The capacity of several coat protein (CP) mutants of a German isolate of barley yellow mosaic bymovirus (BaYMV) to bind of nucleic acids was studied in vitro. Recombinant CP, produced by overexpression in Escherichia coli, was purified from inclusion bodies and subsequently renatured. Binding to single-stranded (ss) RNA and ssDNA oligonucleotides was found to be cooperative and sequence non-spe...
