The Association between Cardiorespiratory Fitness and Gut Microbiota Composition in Premenopausal Women
2017
Abstract The aim of this study was to investigate the association between cardiorespiratory fitness and gut microbiota composition in premenopausal women. The participants consisted of 71 premenopausal Finnish women (aged 19–49 years). Gut microbiota were analyzed using flow cytometry, 16S rRNA gene hybridization and DNA-staining. Maximum oxygen uptake (VO₂ₘₐₓ) was assessed by respiratory gas analyzer and body composition by Bioimpdance. We found that participants with low VO₂ₘₐₓ had lower Bacteroides, but higher Eubacterium rectale-Clostridium coccoides than the high VO₂ₘₐₓ group (p < 0.05 for all). VO₂ₘₐₓ was inversely associated with EreC (r = −0.309, p = 0.01) but not with other bact…
New Insights into the Functional Morphology of the Lever Mechanism of Salvia pratensis (Lamiaceae)
2007
† Background and Aims The functional morphology of Salvia pratensis flowers was re-investigated, after new insights revealed that pollen dispensing is one of the main functions of the staminal lever. In particular, no detailed information was available regarding the process of pollen transfer and the forces arising between the pollen-bearing thecae and the pollinating bee’s body. The assumption was made that these forces play a significant role in pollen dispensing. † Methods The functional morphology of S. pratensis flowers and the interaction between flowers and bees (Apis mellifera) were studied by reconstructing stress and strains by using qualitative and semi-quantitative theoretical a…
Notas corológicas para la flora vascular de la provincia de León (España)
2015
Se aportan datos corológicos sobre varios taxones de plantas vasculares raras o poco frecuentes en la provincia de León (España), muchas de las cuales son especies interesantes en relación a la conservación y están incluidas en catálogos regionales o nacionales de flora amenazada. Cada nueva referencia contiene coordenadas UTM, localización, hábitat recolectores y número de colección. We made chorological additions about several rare or infrequent vascular plants taxa in Leon province (Spain), some of them are very interesting in conservation and included in regional or national list of threatened species. Each new reference contains: UTM coordinates, location, habitat conditions, collectio…
A bug's life: Delving into the challenges of helminth microbiome studies.
2020
The body of vertebrates is inhabited by trillions of microorganisms, i.e. viruses, archaea, bacteria and unicellular eukaryotes, together referred to as the ‘microbiota’. Similarly, vertebrates also host a plethora of parasitic worms (the ‘macrobiota’), some of which share their environment with the microbiota inhabiting the gastrointestinal tract [1]. Complex interactions between the helminths and the gut microbiota have been associated with establishment of parasite infection, disease manifestations, and host immune-modulation [2, 3]. Remarkably, not only enteric helminths alter the 26 gut microbiome composition [4], but also the infection with blood flukes of the genus Schistosoma has be…
6-Prenyloxy-7-methoxycoumarin, a coumarin-hemiterpene ether from Carduus tenuiflorus
1992
Abstract From the acetone extract of Carduus tenuiflorus , a new coumarin-hemiterpene ether was isolated, which was identified as 6-(3,3-dimethylallyloxy)-7-methoxycoumarin. The synthesis of this coumarin and that of its positional isomer 7-(3,3-dimethylallyloxy)-6-methoxycoumarin were carried out from esculetin. Two other coumarins, three lignans and three flavonoids were also isolated.
Allium albanicum (Amaryllidaceae), a new species from Balkans and its relationships with A. meteoricum Heldr. &amp; Hausskn. ex Halácsy
2019
A new species, Alliumalbanicum, is described and illustrated from Albania (Balkan Peninsula). It grows on serpentines or limestone in open rocky stands with a scattered distribution, mainly in mountain locations. Previously, the populations of this geophyte were attributed to A.meteoricum Heldr. &amp; Hausskn. ex Halácsy, described from a few localities of North and Central Greece. These two species indeed show close relationships, chiefly regarding some features of the spathe valves, inflorescence and floral parts. They also share the same diploid chromosome number 2n =16 and similar karyotype, while seed testa micro-sculptures and leaf anatomy reveal remarkable differences. There are …
First finding of Linaria vulgaris (Scrophulariaceae)in Sicily
2007
The occurrence of Linaria vulgaris is reported in Sicily. Such species is known in the Italian Peninsula. Populations of this species have been observed respectively on the Nebrodi Mountains (N Sicily) and in proximity to Aidone (C Sicily).
Data from: Not only for egg yolk - functional and evolutionary insights from expression, selection and structural analyses of Formica ant vitellogeni…
2015
Vitellogenin, a storage protein, has been extensively studied for its egg-yolk precursor role, and it has been suggested to be fundamentally involved in caste differences in social insects. More than one vitellogenin copy has been reported in several oviparous species, including ants. However, the number and function of different vitellogenins, their phylogenetic relatedness and their role in reproductive queens and non-reproductive workers has been studied in few species only. We studied caste biased expression of vitellogenins in seven Formica ant species. Only one copy of conventional vitellogenin was identified in Formica species, and three vitellogenin homologues, derived from ancient …

Flora Ossette’s ‘feminist visibility’ in her translation of Olive Schreiner’s Woman and Labour
2011
La visibilidad del traductor o la traductora se ha convertido en tema obligado en los estudios de traducción desde que Lawrence Venuti editara en 1995 su conocido The Translator’s Invisibility. En la única traducción al castellano de Woman and Labour de Olive Schreiner por parte de Flora Ossette no solo es posible apreciar la voz de la “traductora implícita” (Hermans 1996), sino una voz “explícita”. La traductora interviene activamente en el texto que traduce añadiendo, omitiendo, reorganizando, apostillando o enfatizando las ideas de Schreiner. Además, llevada por los ideales feministas que comparten ambas y por su admiración por la autora sudafricana, se convierte en autora redactando un …
