Ultraviolet B (UVB) irradiation of the skin causes immunosuppression which is relevant to the induction of skin cancer. The mechanism of this immunomodulation is unclear but various regulatory molecules have been implicated, including cis-urocanic acid (cis-UCA) and the cytokines tumour necrosis factor-alpha (TNF-alpha) and interleukin 10 (IL-10). Whether ultraviolet A (UVA) induces similar cha...
We induced experimental allergic encephalomyelitis (EAE) in SJL/J mice, an animal model for multiple sclerosis (MS), using myelin oligodendrocyte glycoprotein (MOG)(92-106) peptide, following ultraviolet (UV) irradiation. While all control mice developed relapsing-remitting (RR)-EAE, UV irradiation induced secondary progressive (SP)-EAE in some of the mice. Although mild demyelination was obser...

Nickel doped TiO2nano particles (1% w/w) were prepared and immobilized on NaX zeolite and after characterization by X-ray diffraction and scanning electron microscopy used as photo catalyts for degradation of orange G. The X-ray diffraction patterns show that the supported TiO2 are crystallized in anatase form and the intensity of the zeolite peaks decreases with the incre...
The purpose of the present study was to evaluate how ultraviolet light <UV) irradiation using an ordinary UV sterilizer would affect the bonding of experimental composite resins to an autopolymerizing acrylic resin. To this end, three composite resins and one unfi11ed resin-of which the compositions were similar to commercial composite resin artifieial teeth were prepared as repair composites. ...
