Over the past century, since rapid development of mankind as a civilization, state environment and conditions everyday human existence have undergone significant changes. Diseases spleen play an important role in system pathologies internal organs. The is often considered “forgotten organ” among clinicians radiologists. Nevertheless, can be involved variety congenital acquired diseases, which m...

Exposure to artificial food colors and additives (AFCAs) has been implicated in the induction and severity of some childhood behavioral and learning disabilities. N-methyl-D-aspartate receptors (NMDARs) and nicotinic acetylcholine receptors (nACHRs) are thought to be effective in the learning and memory-generating process. In this study, we investigated the effects of intrauterine exposure to A...

Problem statement: Current researches had shown that the photostability of a luminescent solar collector depend on the method of its preparation and type of using dye. This research therefore aimed at studying the stability of luminescent solar collector prepared by sol-gel spin coating method using Ponceau 2R. Approach: The effect of silica matrix on the photostability and fluorescence propert...

A simple, sensitive, rapid (3 min), and highly reproducible solid-phase assay for the detection of proteins in the low nanogram range (4 ng) is described. The assay is based on differential Ponceau S staining of the protein spots on nitrocellulose and quantification of the protein-dye complexes on lubricated membranes using a densitometer. The dye solution used for protein staining contained 0....

The precise determination of the colour oils and fats is a common important parameter for production oils, fats, margarine, mayonnaise. A new method has been developed tested in order to improve reliability reproducibility results. It based on values, which describe 3D space as defined by International Commission Illumination (CIE) CIE 1976 (L*a*b*). precision data obtained from collaborative v...

Box-Behnken design was applied to optimize high performance liquid chromatography (HPLC) conditions for the simultaneous determination of potassium sorbate, sodium benzoate, carmoisine, allura red, ponceau 4R, and caffeine in commercial soft drinks. The experimental variables chosen were pH (6.0-7.0), flow rate (1.0-1.4 mL/min), and mobile phase ratio (85-95% acetate buffer). Resolution values ...

Nickel oxide (NiO) nano-size powder is synthesized using nickel (II) acetate tetrahydrate, sodium lauryl sulfate (SLS) and ammonia as precursors. Applied surfactant is anionic surfactant. The sample was characterized by FT-IR, X-ray diffraction (XRD), scanning electron microscopy (SEM). The results obtained confirm the presence of nickel oxide nano-powders produced during chemical precipitation...

OBJECTIVES Most clinical laboratories replaced their manual precipitation techniques for the determination of urinary protein with automated dye binding assays or benzethonium chloride-turbidimetric assays. Few studies have validated these assays for the measurement of urinary proteins in the normal range. DESIGN AND METHODS This study compares four automated assays for the measurement of uri...
