Commercially available amino acids mixtures have several advantages such as enhancing assimilation of fertilizer, facilitating uptake of water and nutrients and improving photosynthesis of plants. To investigate the response of gerbera (Gerbera jamesonni L.) flowers ‘Saltino’ to foliar application of a mixture of 19 essential amino acids (0.25, 0.50 and 0.75 mg L-1) and ammonium nitrate (200 mg...

Amino acid (AA) levels in plasma and erythrocytes (RBC) were determined in rats ( n = 29) fed diets with 6, 21, and 35% protein, and their association with insulin-like growth factor I (IGF-I), insulin, or IGF-binding protein (IGFBP)-1 levels was studied. Free AA in plasma and RBC were determined by reversed-phase high-pressure liquid chromotography, and IGF-I, IGFBP-1, and insulin plasma level...

Odorant specificity to l-alpha-amino acids was determined for 245 olfactory bulb (OB) neurons recorded from 121 channel catfish. The initial tests included 4 amino acids representing acidic [monosodium glutamate (Glu)], basic [arginine (Arg)], and neutral [possessing short: alanine (Ala) and long: methionine (Met) side chains] amino acids that were previously indicated to bind to independent ol...

tuberose (polianthes tuberosa l.) is one of the most important cut flowers in iran. this research was conducted to investigate the effects of spraying a mixture of amino acids on the physiological and morphological characteristics of tuberose. the experiment was carried out in two successive years (2009 and 2010) using two tuberose cultivars ‘dezfuli’ and ‘mahallati’. the experiment was arrange...

The proximate composition, amino acids and fatty acids composition in the muscle of wild, inshore and offshore cage-cultured large yellow croaker, Pseudosciaena crocea (Richardson, 1846), were determined to identify nutritional differences. Wild fish groups showed highest content of moisture and crude protein, but the lowest lipid content. Offshore cage-cultured fish showed significantly higher...

Prodigiosin is a red pigment produced by Serratia marcescens strain. Bacterial prodigiosin and its synthetic derivatives are efficacious antioxidants proapoptotic agents. This study illustrates new approach for use of conjugated silver nanoparticles (PG-AgNP2) against cadmium chloride (CdCl2) induced neurotoxicity in rats. Rats were (ip) injected with Cd (6.5 mg/kg) 7 days or without PG-AgNP2 (...

in an endeavor to find a novel series of antihyperglycemic agents, new benzimidazole and pyrimidine derivatives were successfully synthesized efficiently in high yield with high purity, starting from amino acids in the presence of phosphorus oxychloride (pocl3). the synthesized compounds were identified by 1h-nmr, 13c-nmr, ft-ir spectroscopic techniques and elemental analysis. all products were...

an experiment was conducted to determine apparent ileal digestibility of crude protein (cp) and amino acids (aa) and digestible cp and aa of fish meal (fm) in 21-d-old broiler chickens using the regression technique. four diets containing 0, 1, 2, and 3% fm in place of cornstarch were formulated with fm as the sole contributor of cp and aas in the sequential diets. eighty 14-d-old broiler chick...
