Socio-Demographic Variables, Fear of COVID-19, Anxiety, and Depression: Prevalence, Relationships and Explanatory Model in the General Population of …
2021
The COVID-19 pandemic has gravely impacted Latin America. A model was tested that evaluated the contribution of socio-demographic factors and fear of COVID-19 on anxiety and depression in samples of residents in seven Latin American countries (Argentina, Ecuador, Mexico, Paraguay, Uruguay, Colombia, and El Salvador). A total of 4,881 individuals, selected by convenience sampling, participated in the study. Moderate and severe levels of depressive symptoms and anxiety were identified, as well as a moderate average level of fear of COVID-19. In addition, it was observed that about a quarter of the participants presented symptoms of generalized anxiety disorder and a major depressive episode. …
Mast cells partly contribute to allergic enteritis development: Findings in two different mast cell-deficient mice
2021
Allergic enteritis (AE) is a gastrointestinal form of food allergy. The presence of mast cells and granulocytes has been detected in the inflamed tissues in AE. In this study, we aimed to elucidate the role of mast cells in AE development using two mast cell-deficient mouse strains: KIT(W-sh/W-sh) bearing the W-sash (W(sh)) inversion mutation and Cpa3Cre/+, which lack mast cells due to Cre-mediated mast cell eradication, were used in an AE experimental model. The development of clinical symptoms (e.g. drop in body temperature and weight loss) were abolished in both strains, whereas inflammatory levels of AE (e.g. villous atrophy, edema, and granulocyte accumulation) were reduced mainly in K…
Rebecca abused: a comparative analysis of censorship in the novel and its film adaptation
2019
En 1938, la escritora inglesa Daphne du Maurier (1907-1989) completaba la escritura de Rebecca. En 1940, se estrenaba la adaptación cinematográfica, dirigida por Alfred Hitchcock. La escasa estima que sentía Hitchcock por la novela original, así como los fundamentos del puritano Código Hays (1930), hicieron que el guion original tuviera que ser enmendado. Paralelamente, en 1938, se imponía en España la Ley de Prensa, que pondría al servicio del régimen franquista toda la producción literaria. Sin embargo, la censura franquista dio carta blanca a Rebeca (novela y adaptación cinematográfica). En este trabajo analizamos los comportamientos censores de ambos códigos, coetáneos y similares en cu…

Heterophyid trematodes (Digenea) from penguins: A new species of Ascocotyle Looss, 1899, first description of metacercaria of Ascocotyle (A.) patagon…
2019
Two species of heterophyid trematodes were found in the Magellanic penguin, Spheniscus magellanicus (Forster), from Patagonia, Argentina. Ascocotyle (Ascocotyle) patagoniensis Hernández-Orts et al. (2012) is re-described based on new, properly fixed specimens (original material from South American sea lion, Otaria flavescens Shaw, was from frozen hosts). Metacercariae of this species are reported and described for the first time from the heart of the silversides, Odontesthes argentinensis (Valenciennes) and O. smitti (Lahille), from Patagonia. Ascocotyle (Phagicola) cameliae n. sp. is described from the intestine of S. magellanicus. The new species is placed into the subgenus Phagicola Faus…
Strategic use of pictorial representations in a science text with a biographical seductive detail in low prior knowledge readers
2015
La Teoría Cognitiva de Aprendizaje Multimedia (Mayer, 2001, 2005) sostiene que el procesamiento conjunto de información lingüística y pictórica resulta en una representación mental integrada del mensaje, y que la adición de representaciones pictóricas puede tanto beneficiar como perjudicar el desempeño asociado a la lectura, dependiendo de la función que cumplan dichos agregados. Este estudio examinó experimentalmente el efecto de asociar representaciones pictóricas con un texto expositivo en castellano (una población sub-representada) que incluyó un dato biográfico tangencial pero interesante (detalle seductor). Ciento cuarenta y siete participantes con bajo conocimiento previo leyeron el …
„Vojna není kojná”, czyli koszarowy humor w warunkach totalitaryzmu
2020
Artykuł prezentuje językowe sposoby osiągania efektu komicznego przez Miloslava Švandrlíka w powieści humorystycznej Černí baroni. Są to m.in. łączenie elementów z różnych odmian języka czeskiego (spisovná čeština, obecná čeština,gwary) lub czeszczyzny i języka słowackiego, wprowadzanie wulgaryzmów, słownictwa ska to logiczne go i inwektyw do języka propagandy totalitarnej, kontrast formy i treści, paralelizm składniowy. Podkreślone zostają istotne funkcje społeczne śmiechu jako reakcji na humor szczególnie w trudnym czasie życia społecznego, jakim był okres komunistyczny, np.: terapeutyczna, integracyjna i separująca.
Polymeric monolithic microcartridges with gold nanoparticles for the analysis of protein biomarkers by on-line solid-phase extraction capillary elect…
2020
In this study, polymeric monoliths with gold nanoparticles (AuNP@monolith) were investigated as microcartridges for the analysis of protein biomarkers by on-line solid-phase extraction capillary electrophoresis-mass spectrometry (SPE-CE-MS). “Plug-and-play” microcartridges (7 mm) were prepared from a glycidyl methacrylate (GMA)-based monolithic capillary column (5 cm x 250 µm i.d.), which was modified with ammonia and subsequently functionalized with gold nanoparticles (AuNPs). The performance of these novel microcartridges was evaluated with human transthyretin (TTR), which is a protein related to different types of familial amyloidotic polyneuropathies (FAP). Protein retention depended on…
Guidelines for the use and interpretation of assays for monitoring cell death in higher eukaryotes
2009
Cell death is essential for a plethora of physiological processes, and its deregulation characterizes numerous human diseases. Thus, the in-depth investigation of cell death and its mechanisms constitutes a formidable challenge for fundamental and applied biomedical research, and has tremendous implications for the development of novel therapeutic strategies. It is, therefore, of utmost importance to standardize the experimental procedures that identify dying and dead cells in cell cultures and/or in tissues, from model organisms and/or humans, in healthy and/or pathological scenarios. Thus far, dozens of methods have been proposed to quantify cell death-related parameters. However, no guid…
“LA BECCACCIA IN ITALIA: APPROFONDIMENTI SUL RUOLO DELL’ITALIA NELLA STRATEGIA MIGRATORIA E DI SVERNAMENTO PER LA SPECIE”
La presente ricerca ha lo scopo di apportare nuovi dati della fenologia delle popolazioni di beccaccia che sostano durante i mesi invernali in Italia o che utilizzano la nostra penisola come area di migrazione e di sosta per raggiungere altri paesi.Fonte principale delle analisi è il database nazionale di inanellamento delle catture e ricatture della specie messo a disposizione dal Centro Nazionale di Inanellamento (ISPRA). Lo studio degli individui catturati, marcati con anello alfanumerico unico e rilasciati, dopo aver raccolto importanti dati biometrici, permette di ottenere informazioni della fenologia della specie sul territorio italiano nei mesi post-riproduttivi; di studiare i trend …
