1. The density-gradient distribution patterns of acid phosphatase, Trypan Blue and denatured (125)I-labelled albumin were studied by discontinuous sucrose- and isopycnic sucrose-density-gradient centrifugation on combined heavy and light mitochondrial (M+L) fractions of liver isolated from normal rats and from rats injected with Triton WR-1339. 2. The results obtained from the subfractionation ...

The spontaneous mutant 7B-1 in tomato (Solanum lycopersicum=Lycopersicon esculentum) is a photoperiod-dependent male-sterile mutant previously reported as resistant to various abiotic stresses specifically under blue light. Since this finding improved the potential of 7B-1's use in breeding programmes, its susceptibility to stress induced by coronatine (COR), the phytotoxine produced by several...

Ion-pairing high performance liquid chromatography (IP-HPLC) was utilized to monitor the composition changes of blue gel pen ink entries on paper stored in different light conditions and natural environment. The chromatographic conditions were optimized by comparing the separation efficiencies of the blue gel pen inks using a series of ion-pairing reagents, including ammonium carbonate, ammoniu...

The effect of L-glutamic acid on the embryolethal and teratogenic action of trypan blue was investigated in Wistar albino rats. L-glutamic acid was either incorporated into the diet, from gestation day 2 to day 20, or suspended in sesame oil and administered by gavage, from gestation day 6 to day 10. The day of finding sperm in the vaginal smear was designated day 0 of pregnancy. A teratogenic ...

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...
