Our objective was to examine the effect of orange juice and hesperetin on serum total antioxidant capacity (TAC), lipid peroxidation (MDA), uric acid and hepatic xanthine oxidase (XO) and xanthine dehydrogenase (XDH) activity in hyperuricemic rats. Experimentally hyperuricemia in rats was induced by intraperitoneal injection of potassium oxonate (250 mg/kg). Orange juice (5 ml/kg) and hespereti...

This study compared the concentration of ascorbic acid between citrus fruits collected from the farm of Kerman in Iran. Determination of ascorbic acid was carried out using a liquid chromatography coupled to a diode array detector, with reverse phase and isocratic elution. The validation parameters showed efficiency, adequate linearity, relative standard deviation values 0.02 % (n=10) for repea...

In vitro growth of explant (juice vesicle or albedo tissues) cultures from citron (Citrus medica), lemon (C. limon), grapefruit (C. paradisi), sweet orange (C. sinensis), and mandarin (C. reticulata) fruits was stimulated by addition of orange juice (10% v/v optimum) to a basal medium containing Murashige and Skoog salts, 50 grams per liter sucrose, 100 milligrams per liter myo-inositol, 5 mill...

Kinetics of anaerobic biodecolourisation (methanogenic environment) of four azo dyes (Acid Orange 6, Acid Orange 7, Methyl Orange and Methyl Red) was investigated with regard to their electrochemical properties as well as under variation of dye and sludge concentrations, pH and temperature. Cyclic voltammetry revealed a correlation between the potential of irreversible reduction peak of the dye...

BACKGROUND 6',7'-Dihydroxybergamottin is a furanocoumarin that inhibits CYP3A4 and is found in grapefruit juice and Seville orange juice. Grapefruit juice increases the oral bioavailability of many CYP3A4 substrates, including cyclosporine (INN, ciclosporin), but intestinal P-glycoprotein may be a more important determinant of cyclosporine availability. OBJECTIVES To evaluate the contribution...

As cancer-related deaths continue to rise, developments in nanotechnology have emerged as a feasible option for finding successful treatments targeting cancerous cells while avoiding all of the drawbacks traditional drugs. Selenium nanoparticles (SeNPs) been reported exhibit an inhibitory effect on cells. The aim present study was use drug delivery systems poly(lactic-co-glycolic acid) (PLGA) a...

Soil pH, soil acidity, and their effects on plants The pH scale, ranging from 0 to 14, is used to indicate acidity and alkalinity. pH is a measure of the concentration of hydrogen ions (symbol = H) in the water contained in the soil. A pH of 7.0 is neutral, values below 7 are acidic, and those above 7 are alkaline (basic). The lower the pH, the more acid the soil. Each unit pH drop indicates te...

OBJECTIVE Our objective was to determine whether Seville orange juice produces a grapefruit juice-like interaction with felodipine and whether bergamottin, 6',7'-dihydroxybergamottin, or other furocoumarins are involved. METHODS In a randomized three-way crossover design, 10 volunteers received a felodipine 10-mg extended-release tablet with 240 mL of Seville orange juice, dilute grapefruit j...
