Galangin ameliorates cisplatin-induced nephrotoxicity by attenuating oxidative stress, inflammation and cell death in mice through inhibition of ERK and NF-kappaB signaling.

Cisplatin is a chemotherapeutic agent widely used in the treatment of various cancers. However, cisplatin can induce nephrotoxicity and neurotoxicity, limiting its dosage and usage. Galangin, a natural flavonol, has been found to exhibit anti-oxidant and anti-inflammatory effects in vivo.

Surface roughness effects on aluminium-based ultraviolet plasmonic nanolasers.

We systematically investigate the effects of surface roughness on the characteristics of ultraviolet zinc oxide plasmonic nanolasers fabricated on aluminium films with two different degrees of surface roughness. We demonstrate that the effective dielectric functions of aluminium interfaces with distinct roughness can be analysed from reflectivity measurements. By considering the scattering losses, including Rayleigh scattering, electron scattering, and grain boundary scattering, we adopt the modified Drude-Lorentz model to describe the scattering effect caused by surface roughness and obtain the effective dielectric functions of different Al samples.
