objective(s) studies have described immunomedulatory effects of sun exposure and ultraviolet radiation on infectious and neoplastic diseases. here the effect of exposure to low potency radiation of sun on the course of leishmaniasis in mice was studied. materials and methods fifteen balb/c mice were exposed to suberythemogenic doses of sun (mean 180 mj/cm2/day of uvb) 2 months before and 4 mont...

Vitiligo and Lichen Planus, two common dermatologic disorders, are expected to coexist. This leads to diverse theories regarding their immunopathogenesis linkage. In this case, we report a twenty-year-old man suffering from simultaneous lichen planus and vitiligo which were both generalized at the time of observation and also concomitant throughout their entire course of progression. Lichen Pla...

Este artigo constitui a primeira análise bibliométrica das 708 comunicações publicadas pelo Congresso Nacional de Bibliotecários, Arquivistas e Documentalistas entre 1985 e 2012, tendo-se desenvolvido indicadores de produção, de produtividade, de proveniência institucional e análise temática, numa perspectiva quantitativa, relacional e diacrónica.

OBJECTIVES The aim of this study was to describe outdoor workers' sun-protective practices, workplace sun-safety culture and sun-protective equipment provision; investigate the association of demographic, personal and occupational factors with sun-protective practices; and identify potential strategies for improving workers' sun protection. METHODS The present study used a clustered survey de...

We prove Gaussian estimates for heat kernels on semisimple Lie groups by using the method of Bloch wave representation. We also give a large time asymptotic expansion for heat kernels on compact extensions of abelian Lie groups.

This article has three goals. First, we generalize the result of Deuring and Serre on the characterization of supersingular locus to all Shimura varieties given by totally indefinite quaternion algebras over totally real number fields. Second, we generalize the result of Ribet on arithmetic level raising to such Shimura varieties in the inert case. Third, as an application to number theory, we ...

Bloch points in permalloy cylinders are investigated using a micromagnetic framework, where thermal effects are included via the Landau-Lifshitz-Bloch equation of motion. We show that this enables micromagnetic modeling of a Bloch point avoiding the problem of singularities, which have been rep0l1ed in the literature so far. The details of the Bloch point which we reveal are compared with earli...
