In contrast to ultraviolet and infrared irradiation, which are known to facilitate cutaneous photoaging, immunosuppression, or tumour emergence due to formation of free radicals and reactive oxygen species, potentially similar effects of visible light on the human skin are still poorly characterized. Using a blue-violet light irradiation source and aiming to characterize its potential influence...

BACKGROUND: Candida spp and Malassezia cause superficial infections that may be resistant to conventional treatments. Violet light-emitting diodes (LEDs) therapy is a therapeutic alternative. PURPOSE: To describe the protocol for evaluating antifungal effect of violet LEDs 410 nm ± 10 on in vitro. PROTOCOL: are applied fungal suspension at fluences 61.13 J/cm2, 91.70 183.39 J/cm2. The isolates ...

The low cost adsorbents namely Rice Husk Carbon (RHC), Wheat Straw Carbon (WSC) and Saw Dust Carbon (SDC) have been tested for the effectiveness in decolourisation of wastewater containing a mixture of dyes. Three dyes namely crystal violet, direct orange and magenta have been used for imparting colour in the representative samples of wastewater. Effect of various parameters such as agitation t...

One 3D Cu(II)-based metal-organic framework {[Cu3(tmpa)2(1,2,3-btc)2(H2O)2].14H2O.2DMF}n (Cu(tmpa)) (tmpa ​= ​tris(4-(2-methyl-1H-imidazole-1-yl)phenyl)amine, 1,2,3-H3btc ​1,2,3-benzenetricarboxylic acid) was prepared by hydrothermal method and characterized. Cu(tmpa) exhibits (3,3,4)-connected topology showing point symbol of (6·8·9)2(6·8·10)2(62·82·102). The heterostructural Cu(tmpa)/CN compo...

background the treatment of onychomycosis is a challenge and infections are typically more severe and difficult to treat in toenails than in fingernails. objectives the current study aimed to investigate the fungicidal effect of ultraviolet radiation on the growth of dermatophytes isolated from nails. patients and methods samples from patients with clinical manifestations of onychomycosis were ...

Abstract: WDM multilayered SiC/Si devices based on a-Si:H and a-SiC:H filter design are approached from a reconfigurable point of view. Results show that the devices, under appropriated optical bias, act as reconfigurable active filters that allow optical switching and optoelectronic logic functions development. Under front violet irradiation the magnitude of the red and green channels are ampl...
