More and more research is being focused on the production of value-adding products from waste materials. Food not only a major global issue, but also an excellent source bioactive compounds. In this study, parameters that affect extraction compounds (polyphenols, ascorbic acid, hesperidin, carotenoids) orange peels, their antioxidant properties, were optimized, using response surface methodolog...

Adsorption of violet B azo dye from aqueous solutions was studied by different cellulose agricultural waste materials (almond shell (AS), pistachio shell (PS), walnut shell (WS), Tea waste (TW) and orange peel (OP)). Cellulose agriculturalwaste sorbents characterized by FTIR and SEM methods. The effects of different parameters such as contact time, pH, adsorbent dosage and initial dye concentra...

The applicability of TiO 2 nanoparticles (TiO 2 -NPs-AC) for removing Disulfine Blue (DSB) and Methyl Orange (MO) from aqueous solutions has been reported.The influence of nanoparticle loaded on activated carbon (TiO 2 -NPs-AC) dosage, pH of the sample solution, individual dye concentration, contact time between the sample and the adsorbent were studied by central composite design(CCD) under re...

The capability of Prunus amygdalus L. (almond) shell for dye removal from aqueous solutions was investigated and methyl orange was used as a model compound. The effects of operational parameters including pH, ionic strength, adsorbent concentration and mesh size, dye concentration, contact time, and temperature on the removal of dye were evaluated. The adsorption kinetics conformed to the pseud...

We report here the details of G4-FID (G-quadruplex fluorescent intercalator displacement), a simple method aiming at evaluating quadruplex-DNA binding affinity and quadruplex- over duplex-DNA selectivity of putative ligands. This assay is based on the loss of fluorescence upon displacement of thiazole orange from quadruplex- and duplex-DNA matrices. The original protocol was tested using variou...

ABSTRACT Phytophthora nicotianae and P. palmivora infect and cause rot of fibrous roots of susceptible and tolerant citrus rootstocks in Florida orchards. The infection and colonization by the two Phytophthora spp. of a susceptible citrus host, sour orange (Citrus aurantium), and a tolerant host, trifoliate orange (Poncirus trifoliata), were compared using light and electron microscopy. Penetra...

Immediate allergic reactions to orange are rare and immunoglobulin (Ig) E–mediated [1]. We report the case of a 28-year-old man with anaphylaxis induced by fresh orange juice. The reaction was dose-dependent and could only be confi rmed by challenge test, because specifi c IgE to orange was undetectable by skin prick test (SPT) and CAP immunoassay. The patient had experienced identical anaphyla...

Electroretinogram (ERG) experiments on the sparid fish Chrysophrys auratus (Forster 1801) demonstrated an ontogenetic shift in spectral sensitivity, from long wavelengths (yellow-orange) in small (60 g) fish, to shorter wavelengths (blue) in larger (800 g) fish. Changes in spectral sensitivity are consistent with the life history of the species, since juveniles migrate from predominantly long w...

objective(s) previous studies have demonstrated that the nitric oxide (no) dependent death of murine peritoneal macrophages activated in vitro with ifn-g and lps is mediated through apoptosis. in the present study, we investigated the synergistic effect of lps, ifn-g and iron on no production and apoptosis. materials and methods after determination of iron cytotoxicity, the peritoneal macrophag...
