background: to study methaemoglobin content and nadh-methaemoglobin reductase activity of three human erythrocyte genotypes (hbaa, hbas and hbss).materials and methods: studies to ascertain methaemoglobin concentration and level of nadh-methaemoglobin reductase activity of three human erythrocyte genotypes (hbaa, hbas and hbss) were carried out in forty-three (43) healthy male participants of c...

A new series of 1,2-diaryl-4,5,6,7-tetrahydro-1H-benzo[d]imidazoles, possessing trimethoxy phenyl pharmacophore, were synthesized to evaluate their biological activities as tubulin inhibitors. Cytotoxic activity of the synthesized compounds 7a-f was assessed against several human cancer cell lines, including MCF-7 (breast cancer cell), HEPG2 (liver hepatocellular cells), A549 (adenocarcinomic h...

fractions obtained from partitioning of aerial methanolic extract of euphorbia aellenii with chloroform (e2), ethyl acetate (e3), n-butanol (e4) and water (e5) were investigated in vitro for their phytotoxicity, insecticidal, anti-leishmanial, cytotoxicity, antibacterial and antifungal activities. sample e2 appeared to have significant phytotoxic activity. in the insecticidal screening study on...

theistic philosophers have special view on human nature. they define it in terms of rational faculty and thus regard human final perfection and ultimate felicity dependent on the activity of this faculty and actualization of it. there are philosophers, such as plato, plotinus, and zakariya al-razi (rhazes), who maintain explicitly that human felicity is based on his becoming philosopher. other ...

The hemopoietic activity of the human placenta was studied in vitrc under various conditions in order to assess the optimal conditions of protein synthesis and colony stimulating factor (CSF) production by this tissue. The hemopoietic activity of placental tissue was assayed by the semi -solid agar medium technique. In order to obtain maximum hemopoietic activity, various stimulators were ...

Background: Calprotectin is cytotoxic agent that its anti-tumor effects are governed through suppression of topoisomerase II a key enzyme in apoptosis. In previous studies, cytotoxicity and apoptotic effects of calprotectin are shown on different cancer cell lines, but not human gastric cancer cell lines. In the present study, cytotoxicity and apoptotic effects of calprotectin on human gastric ...

A classical activity theory has for long been established as a de-facto framework on which many human activity models and recognition algorithms are based. We observed several limitations to the classical activity theory, mostly attributed to its inability to discern among seemingly similar concepts and artifacts. We discuss these limitations and introduce a generic activity framework that addr...
