Quercetin against MCF7 and CAL51 breast cancer cell lines: apoptosis, gene expression and cytotoxicity of nano-quercetin.
Nanomedicine (Lond)

Unit of Applied Sciences Research, Department of Applied Science, University of Technology, Baghdad,10066, Iraq.
To evaluate the anti breast-cancer activity, biocompatibility and toxicity of poly(d,l)-lactic--glycolic acid (PLGA)-encapsulated quercetin nanoparticles (Q-PLGA-NPs). Quercetin was nano-encapsulated by an emulsion-diffusion process, and the nanoparticles were fully characterized through Fourier transform infrared spectroscopy, x-ray diffractions, FESEM and zeta-sizer analysis. Activity against CAL51 and MCF7 cell lines were assessed by DNA fragmentation assays, fluorescence microscopy, and acridine-orange, and propidium-iodide double-stainings.

Luminescence
November 2019
Nuclear Technology Research Centre, Faculty Science and Technology, University of Kebangsaan Malaysia (UKM), Bangi, Selangor, Malaysia.
Article Synopsis
- Successfully synthesized Gd O S:Eu nanophosphors using microwave and γ-irradiation methods, with polyvinyl pyrrolidone acting as a stabilizer.
- Both methods produced hexagonal phase nanophosphors with spherical structures, measuring ~90 nm and ~50 nm in diameter.
- Under 325 nm UV light, strong red emissions were observed, with microwave-treated nanophosphors showing better luminescence intensity than those treated with γ-irradiation, attributed to differences in crystallinity and surface effects.
Integrated models for solid waste management in tourism regions: Langkawi Island, Malaysia.

The population growth, changing consumption patterns, and rapid urbanization contribute significantly to the growing volumes of solid waste that are generated in urban settings. As the rate of urbanization increases, demand on the services of solid waste management increases. The rapid urban growth in Langkawi Island, Malaysia, combined with the increasing rates of solid waste production has provided evidence that the traditional solid waste management practices, particularly the methods of waste collection and disposal, are inefficient and quite nonsustainable.
