Digital holographic microscopy: a noninvasive contrast imaging technique allowing quantitative visualization of living cells with subwavelength axial accuracy.

We have developed a digital holographic microscope (DHM), in a transmission mode, especially dedicated to the quantitative visualization of phase objects such as living cells. The method is based on an original numerical algorithm presented in detail elsewhere [Cuche et al., Appl. Opt. 38, 6994 (1999)]. DHM images of living cells in culture are shown for what is to our knowledge the first time. They represent the distribution of the optical path length over the cell, which has been measured with subwavelength accuracy. These DHM images are compared with those obtained by use of the widely used phase contrast and Nomarski differential interference contrast techniques.

Desafios do modelo brasileiro de inclusão digital pela escola

Este artigo discute os rumos da política pública de inclusão digital nas escolas com base nos resultados da pesquisa de avaliação de impacto e de processo do Projeto UCA-Total (Um Computador por Aluno) realizada em cinco municípios onde foi implementado no decorrer de 2010 e 2011. A avaliação de impacto, de caráter longitudinal, foi feita através de um survey domiciliar aplicado em duas ondas. A pesquisa de processo associou diversas metodologias qualitativas, como grupos focais, entrevistas e visitas a campo. Limita-se aqui aos resultados derivados da pesquisa de painel, que revelam o baixo nível de aproveitamento do Projeto e um padrão de funcionamento bastante divergente em razão de vantagens e debilidades locais. Seu enorme potencial não foi até hoje completamente aproveitado.

Cell morphology and intracellular ionic homeostasis explored with a multimodal approach combining epifluorescence and digital holographic microscopy.

The authors have developed a live-cell multimodality microscope combining epifluorescence with digital holographic microscopy; it has been implemented with a decoupling procedure allowing to separately measure from the quantitative phase important cell parameters including absolute volume, shape and integral intracellular refractive index. In combination with the numerous different specific fluorescent cellular probes, this multimodality microscopy can address important issues in cell biology. This is demonstrated by the study of intracellular calcium homeostasis associated with the change in cell volume, which play a critical role in the excitotoxicity-induced neuronal death.
