Texte intégralBackground: Vitamin D comes in two different forms, D3 from animals (cholecalciferol) and D2 from plants (ergocalciferol). There has been different opinions among physicians and the general public about which of the calciferols is more potent to raise 25(OH)D-levels in the blood, which is the value that is measured to determine the vitamin D-status in the body. Since vitamin D deficiency is common among the people of the Nordic countries it is important to know which form has the best effect and should be used to treat and prevent vitamin D deficiency. Furthermore, it is relevant for vegans who do not eat the animalic D3, where recommendations might have to be changed. Aim: The aim of the study was to find out if there were differences in potency of D2 vs. D3 to raise 25(OH)D status in the blood and if so, to find possible explanations for those differences. Methods: Six relevant original articles that examined the effect of D2 vs. D3 on 25(OH)D status in the blood, were found in the database PubMed. The studies where published between the years 2008 and 2017. The participants were healthy adults. Results: Four of the studies suggested that D3 is more effective than D2 in order to raise the 25(OH)D status. One study concluded that there is no difference in the effectiveness of D2 vs D3 and one study showed that D2 is more effective than D3 when it comes to daily treatment but that D3 has a better effect than D2 when treatment happens on a two or four weekly basis with large doses. Conclusion: Most of the articles suggested a better effectiveness of D3 than D2 to raise 25(OH)D levels in the blood. However, besides the mixed results, the number of studies and participants was too small to come to a clear conclusion.

Texte intégralO 3D é uma tecnologia em evolução, quer a nível de dispositivos quer a nível de conteúdos. A sua crescente massificação levanta algumas questões a nível de saúde pública, nomeadamente os efeitos que a visualização destes conteúdos pode ter sobre o sistema visual. Ainda que muita investigação tenha sido feita sobre a sintomatologia que este tipo de conteúdos pode provocar aos seus utilizadores, apenas recentemente se começou a avaliar os seus efeitos sobre o comportamento do sistema visual. Facto que abre um grande leque de oportunidades de investigação. Este trabalho pretende avaliar os efeitos que a visualização de conteúdos 3D tem sobre o sistema acomodativo, comparando a resposta acomodativa a conteúdos 2D e 3D. Para tal foram avaliados dois dispositivos 3D acessíveis ao grande público, a televisão e uma consola de jogos. O estudo foi dividido em duas partes principais relacionadas com o tipo de dispositivo 3D, tendo participado 22 jovens universitários nas experiências realizadas com a televisão e 15 nas realizadas com a consola de jogos. Em termos clínicos, a resposta do sistema acomodativo a conteúdos 2D não é muito diferente da que se verifica para os conteúdos 3D. No entanto parece que a diferença de resposta acomodativa registada para os dois tipos de conteúdos é tanto maior quanto menor for a distância a que são visualizados.
3D is a developing technology, in terms of devices and contents. Its growing mass raises some questions in terms of public health, particularly the effects that viewing such contents may have on the visual system. Although much research was carried out on the symptoms that this type of contents can cause, it has only recently begun to evaluate their effects on the visual system behavior. Therefore there is still a long way to go. This work aims to assess the effects that viewing 3D contents has on the accommodative system, comparing the accommodative response to 2D and 3D contents. Therefore, we evaluated two 3D devices accessible to the general public, television and a video game console. The study was divided into two main parts related to the 3D device type, 22 university students participated in the experiments with television and 15 had performed the experiments with the video game console. In clinical terms, the response to accommodative 2D content is not very different of that found for the 3D content. However it seems that the difference in accommodative response recorded for the two types of content is greater the shorter the distance they are viewed.

Texte intégral2D materials such as graphene, LAPONITE® clays or molybdenum disulfide nanosheets are of extremely high interest to the materials community as a result of their high surface area and controllable surface properties. While several methods to access 2D inorganic materials are known, the investigation of 2D organic nanomaterials is less well developed on account of the lack of ready synthetic accessibility. Crystallization-driven self-assembly (CDSA) has become a powerful method to access a wide range of complex but precisely-defined nanostructures. The preparation of 2D structures, however, particularly those aimed towards biomedical applications, is limited, with few offering biocompatible and biodegradable characteristics as well as control over self-assembly in two dimensions. Herein, in contrast to conventional self-assembly rules, we show that the solubility of polylactide (PLLA)-based amphiphiles in alcohols results in unprecedented shape selectivity based on unimer solubility. We use log Poct analysis to drive solvent selection for the formation of large uniform 2D diamond-shaped platelets, up to several microns in size, using long, soluble coronal blocks. By contrast, less soluble PLLA-containing block copolymers yield cylindrical micelles and mixed morphologies. The methods developed in this work provide a simple and consistently reproducible protocol for the preparation of well-defined 2D organic nanomaterials, whose size and morphology are expected to facilitate potential applications in drug delivery, tissue engineering and in nanocomposites.
