p. atlantica subsp. kurdica, with the local name of baneh, is a wild medicinal plant which grows in kurdistan, iran.  the identification of resistance gene analogs holds great promise for the development of resistant cultivars. a pcr approach with degenerate primers designed according to conserved nbs-lrr (nucleotide binding site-leucine rich repeat) regions of known disease-resistance (r) gene...

sulfuric acid {[3-(3-silicapropyl)sulfanyl]propyl}ester (saspspe) is employed as a recyclable catalyst for the synthesis of α-amino nitriles. these syntheses were performed via a one-pot three-component condensation of aldehydes, amines, and trimethylsilyl cyanide under mild reaction conditions at room temperature. the catalyst could be recycled and reused several times without any loss of effi...

we searched for novel chinese hamster ovary (cho) cell mutants defective in peroxisome biogenesis by an improved method using peroxisome targeting sequence (pts) of pex3p (amino acid residues 1–40)-fused enhanced green fluorescent protein (egfp). from mutagenized tkaeg3(1–40) cells, the wild-type cho-k1 stably expressing rat pex2p and of rat pex3p(1–40)-egfp, numerous cell colonies resistant to...

mutations in the human hepatitis b virus (hbv) genome contribute to its escape from host immune surveillance and result in persistent infections. the aim of this study was to characterize the molecular variations of the surface gene and protein in chronically-infected patients from the southern part of iran. the  surface  genes  from  12  hbv  chronic  carriers  were  amplified, sequenced  and ...

dietary food stimulants decrease feeding time and wasted food. in the present study, effects of adding calcium chloride and free amino acids glutamine to diet on food intake, growth performance and carcass composition of common carp were investigated. the examined food samples were 9.0 mm calcium chloride, 1.0 mm amino acid glutamine 9.0 mm calcium chloride and 1.0 mm glutamine amino acid and t...

Previous results indicated that performance of chicks fed a high level (10%) of poultry by-product meal(PBM) was lower than performance of chicks fed a corn-soybean meal (SBM) diet. The latter difference was hypothesized to be due to variation in digestible amino acid (AA) levels among the diets. This study evaluated diets containing PBM formulated on equivalent total AA basis vs. an equivalent...

prochymosin is one of the most important aspartic proteinases used as a milk-clotting enzyme in cheese production. in the present investigation we report sequence of cdna encoding goat ( capra hircus ) preprochymosin and compare its nucleotide and deduced amino acid sequences with sequences of other ruminants preprochymosin. as bovine prochymosin, the caprine prochymosin cdna encodes 365 amino ...
