Background and objectives: Cancer is a major health problem in the world. The aim of this study was to extract the flowers of Allium austroiranicum used by Iranian people as a condiment or for its medicinal effects followed by bioassay guided fractionation of the extracts and fractions, using anti-proliferative effects against ovarian and cervical cancer cells. <strong...

Background and objectives: Artemisia turanica Krash. grows wildly in north-eastern Iran. The aim of the present work was to undertake an investigation of the antioxidant activity as well as identification of main compound of different extracts and fractions of A. turanica. Methods: Total phenolic contents (TPC) and antioxidant activity of five...

We theoretically study the impact of an external noise on a kinetic mean-field model for the bistable catalytic CO oxidation on Pd(111) surfaces. A spatially homogeneous Gaussian white noise is imposed on the fraction of CO in the constant gas flow directed at the surface and the resulting stochastic system is analyzed by a set of Langevin equations. Using an adiabatic elimination technique, we...

The emission of greenhouse gases and the impact from recycling the organic fraction of solid waste were investigated from a life cycle (LCA) perspective. Three different treatment schemes were investigated with the aid of a pilot apparatus including exclusively composting (COMP), integrated solid anaerobic batch not inoculated and post-composting (SADBPC), and an integrated solid anaerobic batc...

the present experiment was carried out to determine the digestion kinetics of carbohydrate fractions of citrus by-products. grapefruit pulp (gp), lemon pulp (le), lime pulp (li) and orange pulp (op) were the test feed. digestion kinetic of whole citrus by-products and neutral detergent fiber (ndf) fraction and acid detergent fiber (adf) fractions of citrus by-products were measured using the in...

conclusions considering the strong historical background about the therapeutic potential of the genus hypericum and the considerable cytotoxic and apoptosis induction ability of hypericum scabrum, this species is suggested for future biological studies. results di-chloromethane fraction demonstrated ic50 values of 25.72 μg/ml and 24.73 μg/ml against ht-29 and hepg-2 cell lines, respectively and...

Abstract The attributable fraction (population) has attracted much attention from a theoretical perspective and been used extensively to assess the impact of potential health interventions. However, despite its extensive use, there is confusion about concept calculation methods. In this article, we discuss concepts methods for related measures in counterfactual framework, both with without stra...

objective: ipomoea mauritiana is used in both ayurveda and folk medicine systems. the tuberous roots are known to be diuretic, depurative, carminative, and anthelmintic. the objective of the current study was to identify phenolic antioxidants from i. mauritiana using spectrophotometric and lc-ms analysis. materials and methods: an activity-guided fractionation and purification process was used t...
