The chicken retina contains rhodopsin (a rod visual pigment) and four kinds of cone visual pigments. The primary structures of chicken red (iodopsin) and rhodopsin have been determined previously. Here we report isolation of three cDNA clones encoding additional pigments from a chicken retinal cDNA library. Based on the partial amino acid sequences of the purified chicken visual pigments togeth...
A simple, rapid and sensitive method was proposed for online determination of tannic acid in colored tannery wastewater by automatic reference flow injection analysis. Based on the tannic acid reduction phosphotungstic acid to form blue compound in pH 12.38 alkaline solutions, the shade of blue compound is in a linear relation to the content of tannic acid at the point of the maximum absorption...
This study was designed to explore the protective effects of ascorbic acid and water extract of Spirulina platensis (blue green algae) on methotrexate-induced lipid peroxidation using goat liver as the lipid source. This in vitro evaluation was done by measuring the malondialdehyde, 4-hydroxy-2-nonenal, reduced glutathione and nitric oxide content of tissue homogenates....
decolorization of aqueous solutions containing ionic dyes (reactive blue 19 and acid black 172) by a tfc commercial polyamide nanofilter (nf) in a spiral wound configuration was studied. the effect of operating parameters including feed concentration (60-180 mg/l), pressure (0.5-1.1 mpa) and ph (6-10) on dye removal efficiency was evaluated. the response surface method (rsm) was utilized for th...
in this study, removal of methylene blue (mb) and maxilon blue sl 200% (mb sl) dyes from aqueous solutions by using raw clay (rc) of nevsehir (turkey) vicinity and ultrasonic-acid modified clay (mc) was investigated. adsorption was carried out with 500 mg/l mb and 50 mg/l for mb sl in terms of different adsorbent dosages, contact time, solution ph, temperature and stirring speed. the fitting of...
The proper selection and optimization of light gas-permeable membranes in the culture flasks, can benefit plant quality improve ex vitro acclimatization capacity. objective was to compare morpho-physiological responses sugarcane plants different LEDs sealing flask types their impact acclimatization. Plants previously established were used inoculated flasks sealed with rigid caps or without gas-...

Introduction: Goblet cells secrete high molecular weight glycoprotein known as mucin which forms a protective mucus blanket throughout the G.I.T. The present work characterizes histochemically different types of mucin in colonic goblet cells & makes a comparative study in animal species of different food habit. Methods:After ethical clearance tissues were taken from the proximal part of colon o...
