Nowadays, consumers become interested to use the substitution of natural preservatives instead of chemical preservatives. It has been proven that pomegranate peel contains large amounts of antimicrobial and antioxidant compounds. In this study, the antimicrobial effect of ethanolic extract of pomegranate peel was evaluated on total microbial count, mold and yeast and Lactobacillus plantarum...

The treatment of wastewater from the textile industry containing organic dyes faces many challenges since these compounds resist biodegradation process in conventional units. Among physicochemical processes, photocatalysis is considered a facile, cheap, and environmental-friendly technology for treating persistent pollutants waters at low concentrations. This study investigated several factors ...

Pair-fed rats were given diets containing 250 ppm added Cu with or without 5% Senecio jacobaea (S J), a poisonous plant containing the highly toxic pyrrolizidine alkaloids (PA). Levels of Cu, Zn and Fe were determined in whole liver, kidney, spleen, serum and subcellular fractions of liver. Serum ceruloplasmin and hematocrit values were also obtained. At 5 wk, a 7.5-fold increase in liver Cu wa...

objectives in this study, the absorption coefficient of hemoglobin (hb) was used to distinguish between normal and abnormal breast tissue. materials and methods a near-infrared source (637 nm) was transmitted from major and minor vessels of a breast phantom containing 2×, 4× concentrations of oxy- and deoxy-hb. the absorption coefficients were determined from spectrometer (sm) and powermeter (p...

in recent years the use of toxic and carcinogenic synthetic antioxidants are recommended to get limited. therefore, the use of natural resource materials as an alternative substitution for synthetic compounds is indispensable. throughout the present study, antioxidation properties of fennel essential oil, at different concentrations containing 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7 and 0.8 mg/ml in ...

In order to optimize the micropropagation of Qare-Qat (Vaccinium arctostaphylus J.J.Sm), samples were collected from two regions of Iran (Asalem and Kelardasht). Anderson (AN) media containing different concentrations of zeatin (0, 0.5, 1, 2 and 4 mg L-1) and different levels of pH (4.5, 5 and 5.5) were compared. The in vitro shoots were transferred on AN media supplemented with zeatin (1 and 2...
