Resumo: Com a finalidade de se investigar o efeito no Sistema Nervoso Central (SNC) do opióide antagonista naloxone hidrocloride sobre a liberação do hormônio luteinizante (LH) em ovelhas ovariectomizadas e hipoglicêmicas, utilizaram-se oito fêmeas mestiças oriundas das raças Mule e…

Silver halide sensitized gelatin (SHSG) is an interesting technique for the production of holographic optical elements. It combines the high sensitivity of photographic emulsions with the well-known low scattering and high diffraction efficiency corresponding to dichromated gelatin. In this paper…

Foram analisadas oito revistas médicas latino-americanas e oito revistas de circulação internacional, sendo observados os ítens, conforme os Critérios Eticos para Promoção de Medicamentos da OMS: declaração do nome genérico, presença de posologia, composição, reações adversas, precauções, interações medicamentosas e…

Oxidizing agents are powerful activators of factors responsible for the transcriptional activation of cytokine-encoding genes involved in tissue injury. In this study we show evidence that STAT3 is a transcription factor whose activity is modulated by H2O2 in human lymphocytes,…

This study, undertaken in the classrooms of minority-language students in French-language schools in Montreal, aims to test Stern's (1990, 1992) proposal for integrating analytic and experiential teaching strategies in second language pedagogy. A related objective seeks to establish the pedagogical…

The aim of external beam radiotherapy is to deliver a prescribed dose to a target volume accurately and uniformly while sparing the surrounding healthy tissue. In radiation dosimetry calculations, many functions are employed to achieve this goal, and the Peak…

El trabajo comienza por plantear un diseño teórico de los procesos de toma de decisiones de los Estados en materia de política exterior, para luego adentrarse en el análisis teórico de la guerra como institución, sobre las ideas de Von…

Optical densities before bleaching and final Lin curves of planewave phase holograms recorded in Agfa—Gevaert 8E75HD emulsions were measured for various combinations of developers (AAC, Pyrogallol and Catechol) and bleaching agents (R-9 and EDTA). To characterize the processing, the square…

Fixation-free rehalogenating bleaching is an interesting for the production of phase holograms. The shrinkage of the emulsion is reduced in comparison with other bleaching methods (reversal bleaching or rehalogenating bleaching with fixation). In this paper we present experimental results for…
