As negociações entre Portugal e Holanda a respeito da devolução dos territórios portugueses ocupados se desenvolveram ao longo de um decênio. As propostas iniciais de Portugal referiam-se aos territórios ocupados pelos holandeses na África e no Maranhão. Estão nesse raríssimo folheto.

A novel form of human disease with a protease-sensitive prion protein and heterozygosity methionine/valine at codon 129: Case report

Background: Sporadic Creutzfeldt-Jakob disease (sCJD) is a rare neurodegenerative disorder in humans included in the group of Transmissible Spongiform Encephalopathies or prion diseases. The vast majority of sCJD cases are molecularly classified according to the abnormal prion protein (PrPSc) conformations along with polymorphism of codon 129 of the PRNP gene. Recently, a novel human disease, termed "protease-sensitive prionopathy", has been described. This disease shows a distinct clinical and neuropathological phenotype and it is associated to an abnormal prion protein more sensitive to protease digestion. Case presentation: We report the case of a 75-year-old-man who developed a clinical course and presented pathologic lesions compatible with sporadic Creutzfeldt-Jakob disease, and biochemical findings reminiscent of "protease-sensitive prionopathy". Neuropathological examinations revealed spongiform change mainly affecting the cerebral cortex, putamen/globus pallidus and thalamus, accompanied by mild astrocytosis and microgliosis, with slight involvement of the cerebellum. Confluent vacuoles were absent. Diffuse synaptic PrP deposits in these regions were largely removed following proteinase treatment. PrP deposition, as revealed with 3F4 and 1E4 antibodies, was markedly sensitive to pre-treatment with proteinase K. Molecular analysis of PrPSc showed an abnormal prion protein more sensitive to proteinase K digestion, with a five-band pattern of 28, 24, 21, 19, and 16 kDa, and three aglycosylated isoforms of 19, 16 and 6 kDa. This PrPSc was estimated to be 80% susceptible to digestion while the pathogenic prion protein associated with classical forms of sporadic Creutzfeldt-Jakob disease were only 2% (type VV2) and 23% (type MM1) susceptible. No mutations in the PRNP gene were found and genotype for codon 129 was heterozygous methionine/valine. Conclusions: A novel form of human disease with abnormal prion protein sensitive to protease and MV at codon 129 was described. Although clinical signs were compatible with sporadic Creutzfeldt-Jakob disease, the molecular subtype with the abnormal prion protein isoforms showing enhanced protease sensitivity was reminiscent of the "protease-sensitive prionopathy". It remains to be established whether the differences found between the latter and this case are due to the polymorphism at codon 129. Different degrees of proteinase K susceptibility were easily determined with the chemical polymer detection system which could help to detect proteinase-susceptible pathologic prion protein in diseases other than the classical ones.

Phase unwrapping based on branch cut placing and reliability ordering

A new 2-D quality-guided phase-unwrapping algorithm, based on the placement of the branch cuts, is presented. Its framework consists of branch cut placing guided by an original quality map and reliability ordering performed on a final quality map. To improve the noise immunity of the new algorithm, a new quality map, which is used as the original quality map to guide the placement of the branch cuts, is proposed. After a complete description of the algorithm and the quality map, several wrapped images are used to examine the effectiveness of the algorithm. Computer simulation and experimental results make it clear that the proposed algorithm works effectively even when a wrapped phase map contains error sources, such as phase discontinuities, noise, and undersampling.

High-efficiency diffraction gratings in fused silica at the wavelength of 632.8 nm

We describe high-efficiency diffraction gratings fabricated in fused silica at the wavelength of 632.8 nm by rigorous coupled-wave analysis (RCWA). High-density holographic gratings, if the groove density falls within the range of 1575-1630 lines/mm and the groove depth within the range of 1.1-1.3 microns, can realize high diffraction efficiencies at the wavelength of 632.8 nm, e.g., the first Bragg diffraction efficiency can theoretically achieve more than 93% both in TE- and TM-polarized incidences, which greatly reduces the polarization-dependent losses. Note that with different groove profiles further optimized, the maximum efficiency of more than 99.69% can be achieved for TM-polarized incidence, or 97.81% for TE-polarized incidence.

La diversidad de los modelos de participación laboral de las mujeres en la UE-27

[ESP] El objetivo de este artículo es relacionar las características de la inserción laboral femenina con su grado de participación en el mercado laboral en los países de la Unión Europea a través de los datos proporcionados por Eurostat. Nos interesa conocer si una mayor participación laboral entre las mujeres va aparejada con un modelo laboral “femenino”, esto es, con empleos a tiempo parcial, temporales, de baja remuneración y en determinados sectores y ocupaciones. O si por el contrario, en los países en los cuales la tasa de empleo femenina es elevada y hay menor brecha con respecto a la de los hombres, el modelo de inserción laboral de mujeres y hombres es similar. La diversidad de los mercados de trabajo y también de las políticas públicas y de las estructuras productivas en un área tan amplia como al UE27, nos impide establecer modelos de inserción laboral femenina claros, aunque sí hemos podido apuntar rasgos comunes con respecto a las desigualdades de género entre países.

Algunos interrogantes en torno a los programas de inclusión activa como estrategia de lucha contra la pobreza y la exclusión social

Este trabajo estudia los orígenes y el desarrollo de la política de inclusión activa a través del empleo como estrategia de lucha contra la pobreza y la exclusión social. Se indican las otras políticas que, en el marco de la Unión Europea, dificultan o impiden la consecución de los objetivos de la política de inclusión, entre ellas la versión puramente flexibilizadora de la flexiseguridad y las ambigüedades y varias alternativas que plantean las políticas de activación. Se expone la relación de la política de inclusión con las prestaciones económicas de garantía de rentas, con especial detalle al caso de la Comunidad Autónoma del País Vasco y a las nuevas condiciones provenientes de las políticas de recorte del gasto público social impulsadas por las instituciones estatales, comunitarias e internacionales.
