Vitellogenin was obtained from three year-old vitellogenic trout. Two procedures of isolation were compared: dialysis against distilled water and ultracentrifugation in the density interval 1.21-1.28 g/ml. Similar patterns were observed by gel filtration and electrophoresis for both preparations of vitellogenin, indicating that electric charge and molecular weight were not modified by either pr...

Chemical composition is critical information for product quality and exploration of new use. Hence defatted cottonseed meals from both glanded (with gossypol) and glandless (without gossypol) cotton seeds were separated into water soluble and insoluble fractions, or water soluble, alkali soluble as well as total protein isolates. The contents of gossypol, total protein and amino acids, fiber an...

the effect of some treatments including preserving solution (20g l-1 sucrose plus 200 ppm 8-hqs), ba and tdz (pulse or spray) with preserving solution were evaluated on senescence parameters and vase life of rose cut flowers cv. red gant. preserving solution, applying 25 mm ba with preserving solution increased solution absorbance, and prevented the cut flowers from getting decreased in relativ...

Introduction/purpose: In this paper, probability based multi - objective optimization (PMOO) is employed to objectively study the problems of drug encapsulation water-soluble chitosan (WSC) / poly gama glutamic acid ( g -PGA) tanshinone IIA (TA) with a response surface design and glycerosome triptolide an orthogonal experimental design. Methods: PMOO, concept preferable has been introduced desc...

using plant growth regulators at the stresses environment can improve plant growth and crop production. hence, in this research response of photosynthesis rate, chlorophyll, soluble sugar and flower dry weight of chamomile to methyl jasmonate under different salinity levels was studied. values of 0 (control), 75, 150, 225 and 300μm methyl jasmonate (meja) with salinity levels of 2, 6, 10 and 14...

Improved sources of home-grown protein are required to substitute for animal proteins and soyabean meal in ruminant feeds. The present dominance of grassland feeds for protein supply in Britain is highlighted and possibilities for increasing microbial protein (MP) supply on grass-based diets are considered. There are particular opportunities for improving MP supply and animal performance from t...

We compared the values of the biomass, chemical composition and nutritive value of the emergent aquatic macrophyte S. alterniflora in a river affected by the discharge of domestic sewage (Guaú River) and in an unpolluted river (Itanhaém River). S. alterniflora, water and sediment samples were obtained in the two rivers in November, 2001. The Guaú River presented the highest levels of Total-N an...

Tissue osmotic potential and solute constituents were evaluated in leaves and roots of well-watered and water-stressed Prunus avium L. × pseudocerasus Lindl. ‘Colt’ and Prunus cerasus L. ‘Meteor’. Osmotic potential at full turgor decreased in response to water stress for leaves and roots of both cultivars. For ‘Colt’, a cultivar with an indeterminate growth habit, decreased by 0.56 MPa and 0.38...
