parthenolide is major sesquiterpene lactones present in anthemis haussknechtii boiss. & reut. (feverfew). this compound has many effects on different disease such as migrain and cancer. parthenolide was reported from tanacetum parthenium (l.) sch.bip. but other plants of asteraceae family could contain parthenolide. in this study parthenolide was extracted and identified with two methods, fouri...

Introduction: Cardiac glycosides such as digoxin or digitoxin are the natural products that are traditionally used to increase cardiac contractile force in patients with heart failure and cardiac arrhythmias. It has been shown that digoxin can directly inhibit the cell proliferation and lead to cell apoptosis. Present study was conducted to analyze the effect of digoxin in the cohorts of ...

enterohemorrhagic escherichia coli (ehec), such as e. coli o157:h7, are emerging food-borne pathogens worldwide. this micro-organism can damage the epithelial tissue of the large intestine. the cytotoxic effects can be neutralized by probiotics such as bifidobacterium bifidum. probiotics are viable cells that have beneficial effects on the health of the host. the preventing activity of b. bifid...

The cosmic radiation incident at the top of the terrestrial atmosphere includes all stable charged particles and nuclei with lifetimes of order 106 years or longer. Technically, “primary” cosmic rays are those particles accelerated at astrophysical sources and “secondaries” are those particles produced in interaction of the primaries with interstellar gas. Thus electrons, protons and helium, as...

introduction: human calprotectin is an abundant protein in the neutrophil, monocyte and macrophage cytosol. effect of proliferation inhibition of this protein has been elucidated on hepatoma, melanoma, murine fibrosarcoma lukemia and human adenocarcenoma breast cancer but not in human gastric cancer cell lines. in present study, in vitro proliferation inhibition effect of calprotectin in differ...
