Fiscal sustainability analysis: the case of PALOP economies

The Global Financial Crisis has typically led to a significant widening of fiscal positions (i.e., higher budget deficits and public debt). We address the sustainability of public finances in Portuguese-speaking African countries (PALOP), through adequate econometric testing. Our findings for the period 1975-2015 suggest that most of the PALOP have compromised the sustainability of their corresponding fiscal positions, leading these economies to be set on unsustainable public finance trajectories.info:eu-repo/semantics/publishedVersio

Transanal total mesorectal excision with triangle rules: a road map to prevent injuries

[Extract] Transanal total mesorectal excision (TaTME) is presented as a promising new surgical technique for the approach to the distal rectum, providing the ability to perform a highquality resection, with technical advantages over the laparoscopic approach. However, the new surgical anatomy of the TaTME resection complicates surgical understanding and increases the risks of inadvertent injuries to important anatomic structures...info:eu-repo/semantics/publishedVersio

The Galactic O-Star Spectroscopic Survey (GOSSS). III. 142 additional O-type systems

This is the third installment of GOSSS, a massive spectroscopic survey of Galactic O stars, based on new homogeneous, high signal-to-noise ratio, R~2500 digital observations selected from the Galactic O-Star Catalog (GOSC). In this paper we present 142 additional stellar systems with O stars from both hemispheres, bringing the total of O-type systems published within the project to 590. Among the new objects there are 20 new O stars. We also identify 11 new double-lined spectroscopic binaries (SB2s), of which 6 are of O+O type and 5 of O+B type, and an additional new tripled-lined spectroscopic binary (SB3) of O+O+B type. We also revise some of the previous GOSSS classifications, present some egregious examples of stars erroneously classified as O-type in the past, introduce the use of luminosity class IV at spectral types O4-O5.5, and adapt the classification scheme to the work of Arias et al. (2016).Comment: Accepted for publication in ApJS. This version has minor corrections regarding typos and reference

New insights into the cell cycle profile of Paracoccidioides brasiliensis

The present work focuses on the analysis of cell cycle progression of Paracoccidioides brasiliensis yeast cells under diVerent environmental conditions. We optimized a Xow cytometric technique for cell cycle proWle analysis based on high resolution measurements of nuclear DNA. Exponentially growing cells in poor-deWned or rich-complex nutritional environments showed an increased percentage of daughter cells in accordance with the fungus’ multiple budding and high growth rate. During the stationary growth-phase cell cycle progression in rich-complex medium was characterized by an accumulation of cells with higher DNA content or pseudohyphae-like structures, whereas in poor-deWned medium arrested cells mainly displayed two DNA contents. Furthermore, the fungicide benomyl induced an arrest of the cell cycle with accumulation of cells presenting high and varying DNA contents, consistent with this fungus’ unique pattern of cellular division. Altogether, our Wndings seem to indicate that P. brasiliensis may possess alternative control mechanisms during cell growth to manage multiple budding and its multinucleate nature.Fundação para a Ciência e a Tecnologia (FCT) - Contract SFRH/BD/8655/2002, Grant No. POCTI/ESP/45327/ 2002
