This study was an investigation of several Arabic reading measures among dyslexics and normal Arabic readers across different ages (grades 3, 6, 9, and 12): the role of morphology, short vowelization (phonological and syntactic skills), spelling, reading isolated words, and reading comprehension. The results of the one-way ANOVAs indicated clear differences between the dyslexic readers and the ...

Over the past few decades, scientists have paid special attention to studying novel and natural hydrocolloids due to the growing demand for ready meals, public awareness on the importance of natural fibers in daily diets, and their wide range of application, especially in foods, pharmaceuticals and herbal medicine. Moreover, natural hydrocolloids are preferred to biotechnologic ones (e.g., gell...

Microencapsulating sunflower oil, lemon and orange oil flavour was investigated using complex coacervation of whey protein/gum arabic (WP/GA). At pH 3.0-4.5, WP and GA formed electrostatic complexes that could be successfully used for microencapsulation purposes. The formation of a smooth biopolymer shell around the oil droplets was achieved at a specific pH (close to 4.0) and the payload of oi...

An extracellular cell lytic enzyme from Pseudomonas sp. was active on heat killed cells of Xanthomonas campestris. The lytic activity caused enzymatic digestion of X.campestris xanthan gum. Digestion was effective for highly viscous native xanthan 2.0% (w/v) and 2.5% (w/v) commercial Sigma xanthan. Scanning electron microscopy and SDS-PAGE observations confirmed the cell lytic action on X.campe...

Sorafenib is an oral multi-target kinase inhibitor that has been used to treat unresectable hepatocellular carcinoma and advanced renal cell carcinoma. The aim of the study was prepare gum Arabic-chitosan (GA-CS) Arabic-modified chitosan (GA-MCS) microcapsules containing sorafenib as core phase by complex coacervation. fluorescence microscopy, dynamic light scattering (DLS), drug loading, encap...

Acacia senegal is a multipurpose African tree that improves the soil fertility of degraded areas. The species is exploited mainly for gum arabic, but it also supplies fuel wood and fodder for animals. Despite its wide distribution in Africa, no microsatellite markers have yet been characterized for this species. In this study, we characterized 11 polymorphic microsatellite loci specifically des...

Multiferroic ErMn2O5 nanorods have been synthesized via a surfactant-templated hydrothermal route. An environmentally friendly natural surfactant (Arabic gum) has been utilized as a template to prepare ErMn2O5 nanorods with a controllable morphology and size (i.e., nanorods with various lengths and basically invariable diameter). ErMn2O5 nanorods show strong size-dependent magnetic properties t...

Abbreviations. AGP, arabinogalactan protein; EGFP, enhanced green fluorescent protein; GPI, glycosylphosphatidylinositol; GAGP, gum arabic glycoprotein; GT, glycosyltransferase; HRGP, hydroxyproline rich-glycoprotein; LeAGP1, arabinogalactan protein 1 from tomato; Lys, lysine rich domain; P4H, prolyl-4-hydroxylase; (SP), serine-proline repeat; (VP), valine-proline repeats; (TP), threonine-proli...

RATIONALE Recent research has shown that even small doses (<40mg) of caffeine can improve alertness and increase performance efficiency on attention tasks. Previous studies have given the caffeine in a variety of beverages or in capsules and it was of interest to see whether similar effects could be observed when the caffeine was given in gum. In addition, chewing gum has been shown to have beh...
