The cytochrome content of liver mitochondria and microsomes during the carcinogenesis of rat liver by both 3'-methyl-4-dimethylaminoazobenzene (3'-DAB) and 4'methyl-4-dimethylaminoazobenzene (4'-DAB), and of 3'DAB-induced hepatomas, was determined spectrophotometrically at room and liquid nitrogen temperatures and was compared with that of normal liver. The cyto chrome a + a3 content in the liv...

Mysis mixta were reared under laboratory conditions (temperature: 9-10 degrees C; salinity: 7 per thousand, ad libitum food). Dry weight, ash, total carbon and nitrogen content of mysids (muscle tissue, eggs, and embryos of different developmental stages) have been analyzed. We found significant variations in ash content and elemental composition during growth and maturation for both sexes. The...

In normal growth conditions, total protein percent (salt soluble plus hordein fractions) in the endosperm at maturity in barley cultivar Hordeum vulgare L. cv ;Ruth' was about 14%, whereas in an accession of wild barley, Hordeum spontaneum Koch line 297, it was about 28%. Spike culture experiments were conducted to ascertain whether there were basic differences between the two genotypes under c...

Disparities in nutrient content (nitrogen and phosphorus) between herbivores and their plant resources have lately proven to have major consequences for herbivore success, consumer-driven nutrient cycling, and the fate of primary production in ecosystems. Here we extend these findings by examining patterns of nutrient content between animals at higher trophic levels, specifically between insect...

to study the effect of planting dates and genistein application on nitrogen content and nodulation of three annual medic species (medicago polymorpha cv. santiago m. rigidula cv. ragidula, and m. radiata cv. radiata), an experiment was conducted during 2005-2006 in the research farm of faculty of agriculture, shahed university, tehran. the treatments were arranged as split split plot in a rando...

in order to study the effect of vermicompost and nitrogen fixing bacteria on seed yield, yield components of seed and essential oil content of coriander (coriandrum sativum), an experiment was conducted as factorial experiment in the base of randomized complete blocks design with eight treatments and three replications at research field of agriculture company of ran in firouzkuh of iran in 2012...

This experiment was conducted to determine the effects of nitrogen and phosphorus fertilizers on nutritive value of safflower forage and silage by in situ and in vitro methods. The safflower forage was harvested at flowering stage, chopped to 3-5 cm particles and then ensiled in the laboratory silos for 60 days. The experimental treatments included: 1. Unfertilized forage (control), 2. Phosphor...

The dry mass, wet mass, and volume of mitochondria of normal rat liver were determined, as well as nitrogen content and concentration. A scheme of multiple approaches to these quantities was devised, permitting comparison of values obtained by independent methods. The following basic values are considered highly accurate: Mean dry mass, 13.6 x 10(-14) g; mean wet mass, 51.8 x 10(-14) g; mean vo...

in order to study the effect of nitrogen level on physiological characteristics, grain yield and yield components of tetraploid wheat genotypes, a split plot randomized complete block design field experiment with three replications was conducted in 2007 at research farm of isfahan university of technology. four levels of nitrogen fertilizer (20, 80, 140 and 200 kg/ha) were chosen as main plots ...
