for high-throughput production of recombinant protein in escherichia coli ( e. coli ), besides important parameters such as efficient vector with strong promoter and compatible host, other important issues including codon usage, rare codons, and gc content specially at n-terminal region should be considered. in the current study, the effect of decreasing the percentage of gc nucleotides and opt...

in this research the effect of conventional and ohmic pasteurization and storage time at different temperatures on some bioactive components of aloe vera gel juice was investigated. aloe vera gel juice was pasteurized conventionally and ohmically at 90 ºc for 1 min. the effect of pasteurization on vitamin c, total phenolic content  and juice color was evaluated. the samples pasteurized conventi...

The present study describes two different methods for the preparation of superabsorbent polyacrylamide (PAAm) hydrogels for application in farming of sandy soil. The two methods were employed to induce the crosslinking of the polymer matrix. In the first method a PAAm paste was exposed to gamma rays, while in the second method the polymer was thermally treated in the solid phase. Crosslinked PA...

Aloe Vera has gained more attention over the last decade due to its reputable, medicinal, and pharmaceutical and food properties. In present research, firstly the different concentrations of pectin and gum acacia were augmented with aloevera gel and the products so prepared were assessed for texture and stickiness. The selected preparation was then supplemented with orange flavour at different ...

A practical immunologic assay to detect the hormone, prolactin, in body fluids was evaluated. Prolactin content was assayed using positive antiprolactin sera prepared in rabbits and test samples of serum, urine, and urinary extract from a borane exposed female monkey in micro-Ouchterlony gel diffusion and agglutination inhibition tests. The gel diffusion test gave qualitative results while the ...

Background & Aims: The present study compared fluoride uptake into enamel from sodium fluoride 0.05% gel and American Dental Association approved fluoride gel (Stannous fluoride 0.4% , Sultan Co.) when used on healthy enamel of the intact teeth. Methods: In an experimental study, 30 intact teeth extracted for orthodontic purposes were randomly assigned into two groups of 15 teeth. The teeth wer...
