the chemical composition, in situ ruminal degradability coefficients of dry matter (dm), and nutrient digestibility in sheep were evaluated for corn silage (cs) treated (fresh weight basis) with different levels of a commercial bacterial inoculant (i) as follows: (1) untreated cs (control); (2) cs + i at half of the recommended level; (3) cs + i at the recommended level (3  1010 colony forming...

this paper describes the development, electrochemical characterization and utilization of novel modified molybdenum (vi) complex-carbon nanotube paste electrode for the electrocatalytic determination of ascorbic acid (aa). the electrochemical profile of the proposed modified electrode was analyzed by cyclic voltammetry (cv) that showed a shift of the oxidation peak potential of aa about 235 mv ...

background & aim: marigold or calendula officinalis l. is a annual herb belongs to the asteraceae family.  marigold is a valuable medicinal plant which is used in pharmaceutical industry.  in addition, this plant is cultivated as an ornamental plant. aim of current study was to evaluate the effect of different concentrations of jasmonic acid (ja), and salicylic acid (sa) on phytochemical pr...

the silica boron sulfuric acid nanoparticles (sbsans) as an efficient heterogeneous solid acid catalyst with both brønsted and lewis acidic sites catalyzed the preparation of bis-4-hydroxycoumarin derivatives using reaction of aldehydes and 4-hydroxycoumarin under mild and solvent-free condition at room temperature. this new and efficient methodology has advantages in comparison with currently ...

objective(s):the inhibitory effects of iron chelators, and fecl3 chelation on biofilm formation and swarming motility were investigated against an opportunistic human pathogen pseudomonas aeruginosa. materials and methods:the inhibitory activity of 2,2’-bipyridyl, lipoic acid, kojic acid and picolinic acidonbiofilm formation of p. aeruginosa strain pao1 and three clinical isolates (p. aeruginos...

a simple and efficient one-pot, three-component strecker reaction of protected amino acids, aromatic aldehydes, and trimethylsilyl cyanide has been developed for the synthesis of chiral α-amino nitriles. the reaction was carried out in the presence of catalytic amount of phosphotungstic acid (h3[p(w3o10)4]) as an environmentally friendly catalyst.

introduction: nonalcoholic fatty liver disease (nafld) is a global disease which its prevalence is about 10-35%. several factors are involved in the pathogenesis of the disease. the present study was conducted to evaluate the effect of fasting during ramadan on plasma free fatty acids in patients with nafld.methods: this cross-sectional study was performed during the month of ramadan in june-ju...

objective: in order to study the effect of drought stress, salicylic acid (sa) and  jasmonic acid (ja) foliar application on hill reaction and photosynthetic pigments. methods:experiment was done as factorial on the basis of completely randomized design in 4 replications. irrigation in 3 levels (fc,   fc and  fc), salicylic acid in 2 levels (0 and 0.5 mm) and jasmonic acid in 2 levels (0 and 50...
