Background: Dental caries is one of the most common oral diseases in pre-school children. Several factors can affect caries process. Aim of this study was comparison of some of the chemical properties of saliva such as total antioxidant capacity, total protein, pH, nitric oxide level in caries free (CF), and caries active (CA) children.<...

wheat streak mosaic virus (wsmv) causes extensive economic damage to wheat (triticum aestivum l.) in many regions of the world. the present study was conducted to find out if the variations in biochemical changes in reaction to wsmv infection in f2 generation of either potentially resistant (adl-cross) or susceptible (marvdasht) cultivars are genetically inherited. a factorial experiment was em...

expression of htlv-i p19 protein in an escherichia coli expression system always leads to the formation of inclusion body. solubilisation and refolding of the inclusion bodies is complex, time consuming and difficult during large-scale preparation. this study aimed to express and purify a soluble form of recombinant htlv-i p19 protein in an e. coli expression system. the synthetic dna encoding ...

Background: Phthalates are a group of multifunctional chemicals. Diethyl phthalate (DEP) is one of the most frequently used phthalates in solvents and fixatives for numerous industrial products. Method: The present experiment was designed to assess oxidative stress, if any, caused by diethyl phthalate. For this the homogenates of liver and kidney were treated with different concentrations ( 1...

The aim of this study was to evaluate the nutrient digestibility, ruminal fermentation and microbial protein synthesis of mid-lactating cows fed high dietary levels of monensin. Twelve Holstein cows were distributed into four 3 × 3 latin squares and assigned to the following treatments: control (CON), monensin 24 (M24, addition of 24 mg monensin/kg diet DM) and monensin 48 (M48, addition of 48 ...

This research was done in hydroponic environment in greenhouse at 3 stages (vegetative, flowering and full product) in 5 concentrations of Cd (0.1, 0.3, 0.9, 2.7, and 10 mm) for investigating physiological and biological effects. This study revealed that the increase of Cd concentration in understudy treatments causes the 49% reduction of sugar solution in 10 mm treatment. On the other hand, th...

background: bradford protein assay is popular due to its ease of performance and relative sensitivity. many researchers and laboratories in iran use standard assay of bradford by cuvette. no commercial kit was available for bradford microplate assay in iran. meanwhile, imported bradford commercial kits are very expensive and have a long delivery time in iran. till now no study or document on br...
