the present study is aimed at the overall improvement in the efficacy, reduced toxicity and enhancement of therapeutic index of cisplatin. nanocapsules of cisplatin containing ethylcellulose have been prepared using solvent evaporation technique under ambient conditions. the prepared nanocapsules were used for controlled drug release of anticancer agents with gold and iron oxide nanoparticles. ...

The greatest challenge of our time is to meet the global food demand by producing enough without harming environment. Over application and misuse synthetic fertilizer a major that results in lower use efficiency (FUE), stagnated crop yield, environmental pollution. In this review study, three alternative fertilization options (AFOs), such as organic enhanced-efficiency (EEFs), secondary, micron...
