A series of copper(ii) complexes with earlier reported ligands N,N'-bis(2-hydroxyiminopropionyl)-1,2-diaminoethane (H(2)pen) and 1,3-diaminopropane (H(2)pap) and novel open chain oxime and amide ligands, N,N'-bis(2-hydroxyiminopropionyl)-1,5-diaminopentane (H(2)papt), 1,6-diaminohexane (H(2)pah) and 1,7-diaminoheptane (H(2)pahp), were prepared and characterized by a variety of spectroscopic met...

The amino analogues of pentamidine with a polymethylene (n = 3 - 6) chain and their chlorambucil derivatives were synthesized. The obtained compounds revealed cytotoxic effect on MCF-7 human breast cancer cell line (IC50 = 22 - 95 +/- 2 pM), mainly by the induction of apoptosis. The topoisomerase I/II inhibition assay and the ethidium displacement assay with the use of pBR322 plasmid DNA were u...

The present study is focused on the synthesis and investigation of the physicochemical and biological properties of silver nanoparticles stabilized with a series of cationic gemini surfactants having a polymethylene spacer of variable length. UV-VIS spectroscopy, dynamic light scattering, scanning electron microscopy and zeta potential measurements were applied to provide physicochemical charac...

No prior literature explores the influence of green transformational leadership on green performance, thus, this study develops a novel research framework to fill the research gap. This study investigates the influence of green transformational leadership on green performance and discusses the mediation effects of green mindfulness and green self-efficacy by means of structural equation modelin...

background: exercise and consumption of green tea affect the aging process. however, the effect of exercise training combined with green tea extract on leukocyte telomere length, quality of life (qol) and body composition in aging has so far been unclear and inconsistent. objective: the aim of the present study was to determine the effectiveness of aerobic training intervention and green tea ex...

quantitative identification of physical changes, developments and dynamic position of urban green space is considered as the first step in its planning. by means of the aerial photos taken in 1956, 1974, and 1994 as well as the quick bird satellite image captured in 2006, this study has dealt with changes in per capita green space in khorramabad during these years. first, geometric corrections ...

corporate and social responsibility are continuously competing to share a common platform to address a new form of green consumerism that the eco-educated millennial generation can appreciate. green marketing acts as bridge connecting the corporate, environment and consumers. business organizations have begun to respond to social expectations of consumers by opting for holistic environmental st...

polyamide 6 has been widely used in food packaging applications and also green tea contains amounts of antioxidant compounds. the aim of this study was investigation of green tea effects on properties of polyamide packaging polymer. polyamide 6 was dissolved in methanol which was saturated with calcium chloride. the active packaging film was produced by incorporation of methanol green tea extra...
