Razafimandimbison, Kent Kainulainen, Bruno Senterre, Charles Morel, Catarina RydinAbstractThe granitic islands of the Seychelles harbor about 268 native angiosperm species, with 28% being endemics there. The Seychelles biota contains a mix of ancient taxa with Gondwanan origins and young taxa that arrived there via dispersals. We investigate the phylogenetic position of an enigmatic, critically endangered, Seychellean endemic of the coffee family (Rubiaceae), Psathura/Psychotria sechellarum, and assess whet...

In this study, a hydrogeochemical investigation, by interpretations of conservative dissolved ions was used to probe the main mechanisms controlling groundwater salinization and to characterize the associated hydrogeochemical processes occurring in Mediterranean coastal aquifers. Groundwaters of the different aquifers are of meteoric origin and they mostly flow toward the coast. Based on EC and ionic ratios, a hydro-chemical zonation of water types (ranging from Ca-HCO3, Na-HCO3, Ca-Mg-Cl-SO4, Ca-Cl to Na-Cl) from recharge areas toward the coast is revealed. This zonation is mainly controlled by migration and mixing of sal...

Authors: Kim HC, Hong EJ, Ryu SY, Park J, Yu DH, Chae JS, Choi KS, Sim C, Park BK Abstract Avian trematodes, Urogonimus turdi (Digenea: Leucochloridiidae), were collected from the intestine of wild birds, Zoothera aurea, 2013-2017 in the Daejeon Metropolitan City, Korea. The body was ellipsoidal, attenuated and/or round ends, 1,987-2,120 long and 819-831 µm wide. The oral sucker was subterminal, rounded anteriorly, and 308- 425×351-432 µm in size; the prepharynx and esophagus were almost lacking; pharynx was well-developed, 142- 179×78-170 µm in size; intestine narrow, bifurcating just...

o Kawaoka Viral neuraminidase inhibitors show limited efficacy in mice infected with H7N9 influenza A viruses isolated from humans. Although baloxavir marboxil protected mice from lethal challenge infection with a low pathogenic avian influenza H7N9 virus isolated from a human, its efficacy in mice infected with a recent highly pathogenic version of H7N9 human isolates is unknown. Here, we examined the efficacy of baloxavir marboxil in mice infected with a highly pathogenic human H7N9 virus, A/Guangdong/17SF003/2016. Treatment of infected mice with a single 1.5 mg/kg dose of baloxavir marboxil protected mice from the h...

AbstractSocioeconomic inequalities in mortality are a challenge for public health around the world, but appear to be resistant to policy-making. We aimed to identify European countries which have been more successful than others in narrowing inequalities in mortality, and the factors associated with narrowing inequalities. We collected and harmonised mortality data by educational level in 15 European countries over the last 25  years, and quantified changes in inequalities in mortality using a range of measures capturing different perspectives on inequality (e.g., ‘relative’ and ‘absolute’ ineq...

Authors: Rodríguez JM, Luque D Abstract To initiate infection, non-enveloped viruses must recognize a target cell and penetrate the cell membrane by pore formation or membrane lysis. Rotaviruses are non-enveloped dsRNA viruses that infect the mature intestinal epithelium. They are major etiologic agents of diarrheal disease in human infants, as well as in young individuals of various avian and mammalian species. Rotavirus entry into the cell is a complex multistep process initiated by the interaction of the tip of the viral spike with glycan ligands at the cell surface, and driven by conformational changes o...

LITFL • Life in the Fast Lane Medical Blog LITFL • Life in the Fast Lane Medical Blog - Emergency medicine and critical care medical education blog aka Tropical Travel Trouble 009 The diagnosis of HIV is no longer fatal and the term AIDS is becoming less frequent. In many countries, people with HIV are living longer than those with diabetes. This post will hopefully teach the basics of a complex disease and demystify some of the potential diseases you need to consider in those who are severely immunosuppressed. While trying to be comprehensive this post can not be exhaustive (as you can imagine any patient with ...

Abstract Intestinal disease has a major impact on the broiler industry due to economic and welfare reasons. Intestinal disease might occur due to a large number of reasons varying from well-defined pathogens to non-specific enteritis and complex syndromes. However, knowledge about the nature or intestinal disease and presence of enteric viruses in the Dutch broiler industry is largely absent. Therefore, a large scale field study, in which 98 broiler flocks from 86 farms were sampled weekly, was started to assess the prevalence of histopathological lesions in the jejunum, a number of enterotropic viruses by real-ti...
