Gnathostoma spinigerum third stage larvae antigen is necessary for Western blot analysis in the diagnosis of Gnathostomiasis. Acid pepsin solution is required for digestion of eel's liver( Fluta alba ) to yield the larvae for antigen preparation. Here, he reported the feasibility of using orange juice as an alternative to enzyme pepsin in harvesting Gnathostoma spinigerum third stage larvae. Fr...

This study aimed to clarify the ability of the buffer systems of saliva to inhibit enamel demineralization after intake of an acid beverage. In the first experiment, titrable acidity tests were carried out. Ten milliliters of saliva stimulated by chewing gum base was obtained from 10 healthy adult subjects and the pH of each saliva sample was measured. The beverages used for the experiment were...

Seaweeds are rich sources of bioactive natural products, which have been considered as potential biotic agents. Ulva flexuosa Wulfen is a species of seaweed which is endemic to the Persian Gulf. In this study, the effect of different concentrations of U. flexuosa extract on  the  antioxidant activity of Washington Navel orange (Citrus sinensis L. cv. Washington Navel)...

Here, a comprehensive proteomic analysis of the chromoplasts purified from sweet orange using Nycodenz density gradient centrifugation is reported. A GeLC-MS/MS shotgun approach was used to identify the proteins of pooled chromoplast samples. A total of 493 proteins were identified from purified chromoplasts, of which 418 are putative plastid proteins based on in silico sequence homology and fu...

Preliminary studies by Beers et a2. (1) have shown that the zinc salt of acridine orange can either inhibit or accelerate the rate of polymerization of polynucleotides by polynucleotide phosphorylase of Micrococcus lysodeileticus, depending upon the experimental conditions. We have now confirmed these findings with the zinc-free dye. Some evidence for a reversal of inhibition with degraded ribo...

The volatile compounds from Maclura pomifera (Osage orange fruit) peel have been studied by GC-FID and GC–MS. Volatiles fraction proportion was estimated to 60 mg/kg. Identified compounds consist on aliphatics (52.6%), monoterpenes along with sesquiterpenes (27.3%), phenylpropane derivatives along with related compounds (10.0%) and other compounds (10.6%). Among the 60 identified compounds, 1-h...

This research describes a voltammetric approach to determine amounts of vitamin C (Ascorbic acid) in orange juice sample, using three screen printed electrode. The anodic currents of vitamin C were proportional to vitamin C concentration in the range of 0 – 10.0 mM with the limit of detection of 1.36 mM. The method was successfully employed with 2 μL of the working solution dropped on the elect...

To improve the photocatalytic activity of titanium oxide, nanometer oxide powder was mixed with a phosphoric acid solution to form an electrolyte for preparing TiO2/Al2O3 coating on surface aluminum alloy. Hydrothermal technology has been used adjust crystalline structure oxide. Scanning electron microscope observe micromorphology anodic before and after treatment using hydrothermal technology....
