bioactive food components (such as phenolic compounds, carotenoids, anthocyanins, tochopherols, ascorbic acid, flavonoids, minerals, enzymes and pectin) are active ingredients in food or dietary supplements, which proven to have an important role in health, and are safe for human consumption. these compounds exert their antioxidant effects by different mechanisms such as single electron transfe...

Wilms tumor (WT) is the most common pediatric malignant primary renal tumor. Carboplatin (CRB), a platinum compound is widely used in the treatment of multiple cancers including ovarian, lung, head and neck, and wilm’s tumor. However lower uptake of CRB in cancer cells and toxicity concerns in healthy cells often limited its clinical outcome. The aim of this study was to investigate the antitum...

Abstract Organic esters of phosphoric acid and other organophosphorous compounds are enzymatically hydrolyzed during wastewater treatment by microbial phosphoesterases, especially phosphomonoesterase (phosphatase). For physiological reasons, the enzyme is inhibited its main inorganic reaction product, ortho-phosphate. It known that oxyanions transition metals, resembling molecular topology orth...

A comparative study was conducted between two laboratories in order to evaluate the differences between two enzyme-linked immunosorbent assay (ELISA) techniques for the detection of pneumococcal anti-capsular polysaccharide antibodies. One laboratory used an assay including heterologous 22F polysaccharide inhibition, and the other laboratory employed a non-22F reference assay. After conjugate i...

BACKGROUND Standardized techniques to detect HIV-neutralizing antibody responses are of great importance in the search for an HIV vaccine. METHODS Here, we present a high-throughput, high-content automated plaque reduction (APR) assay based on automated microscopy and image analysis that allows evaluation of neutralization and inhibition of cell-cell fusion within the same assay. Neutralizati...

Objective(s):Involvement of tyrosinase in the synthesis of melanin and cell signaling pathway has made it an attractive target in the search for therapeutic inhibitors for treatment of different skin hyperpigmentation disorders and melanoma cancers. Materials and Methods: In the present study, we conducted a comprehensive kinetic analysis to understand the mechanisms of inhibition imposed by 2-...
