Revisión del género Cantabrogeus Salgado, 2000, con la descripción de tres nuevas especies hipogeas endémicas de la Cordillera Cantábrica (Coleoptera, Leiodidae, Cholevinae, Leptodirini)

Se revisan las dos especies previamente descritas del género Cantabrogeus (Coleoptera, Leiodidae, Cholevinae, Leptodirini), y se describen tres especies nuevas: Cantabrogeus antimachus sp. n., C. cultellus sp. n. y C. fresnedai sp. n. Una de ellas (C. antimachus sp. n.) es triploide (3n = 33) y la primera especie partenogenética conocida de Leiodidae. Se analizan y se discuten las relaciones existentes entre los diferentes taxones a partir de los caracteres morfológicos externos y las estructuras de los aparatos genitales masculino y femenino, así como las áreas cársticas que colonizan las diferentes especies en la zona cantábrica (NO ibérico). El análisis de datos moleculares (fragmentos de siete genes mitocondriales y nucleares) confirma la monofilia de Cantabrogeus y su proximidad filogenética con el género Fresnedaella, así como su inclusión dentro de la serie Quaestus, que es parafilética. La especie partenogenética (C. antimachus sp. n.) ocupa una posición derivada dentro del género Cantabrogeus, que, de acuerdo con estimas de la tasa de variación molecular basadas en estudios previos, probablemente se diversificó durante el Plioceno–Pleistoceno en las zonas cársticas cántabras, que son de una alta complejidad tectónica.The two previously known species of the genus Cantabrogeus (Coleoptera, Leiodidae, Cholevinae, Leptodirini) are redescribed, and three new species are described: Cantabrogeus antimachus n. sp., C. cultellus n. sp. and C. fresnedai n. sp. One of these (C. antimachus n. sp.) is tripliod (3n = 33) and the first known parthenogenetic species of Leiodidae. The relationships between the different taxa are discussed based on external morphological characters and the structure of male and female genitalia, as well as the distribution of the species in the different areas in the Cantabrian mountains (NW Iberia). Analyses of molecular data (fragments of seven mitochondrial and nuclear genes) confirms the monophyly of Cantabrogeus and its sister–group relationship with Fresnedaella, as well as its inclusion within the paraphyletic series Quaestus. The parthenogenetic species (C. antimachus n. sp.) has a derived position within Cantabrogeus, which, according to previous estimates of the molecular rate, probably diversified during the Pliocene–Pleistocene in the Cantabrian karst areas, of a high tectonic complexity.Se revisan las dos especies previamente descritas del género Cantabrogeus (Coleoptera, Leiodidae, Cholevinae, Leptodirini), y se describen tres especies nuevas: Cantabrogeus antimachus sp. n., C. cultellus sp. n. y C. fresnedai sp. n.

Socio-cultural factors for breastfeeding cessation and their relationship with child diarrhoea in the rural high-altitude Peruvian Andes - a qualitative study

BACKGROUND: In some areas of the world, breast milk is seen as a potential source of child diarrhoea. While this belief has been explored in African and Southeast Asian countries, it remains vastly understudied in Latin American contexts. We investigate socio-cultural factors contributing to breastfeeding cessation in rural high-altitude populations of the Peruvian Andes. The role of socio- cultural factors in the local explanatory model of child diarrhoea, and whether these perceptions were integrated in the local healthcare system were assessed. METHODS: Within the framework of a randomised controlled trial, we conducted semi-structured interviews with 40 mothers and 15 health personnel from local healthcare centres involved in the trial. RESULTS: Cultural beliefs on breastfeeding cessation included the perception that breast milk turned into "blood" after six months and that breastfeeding caused child diarrhoea. We identified eight local types of child diarrhoea, and women linked six of them with breastfeeding practices. "Infection" was the only diarrhoea mothers linked to hygiene and the germ disease concept and perceived as treatable through drug therapy. Women believed that other types of diarrhoea could not be treated within the formal healthcare sector. Interviews with health personnel revealed no protocol for, or consensus about, the integration of the local explanatory model of child diarrhoea in local healthcare and service provision. CONCLUSIONS: The local explanatory model in rural Andean Peru connected breastfeeding with child diarrhoeas. Cultural beliefs regarding diarrhoea management may increase home treatments, even in cases of severe diarrhoeal episodes. Future national breastfeeding support programmes should promote peer-counselling approaches to reduce negative attitudes towards breastfeeding and health practitioners. Local explanatory models should be incorporated into provincial and regional strategies for child diarrhoea management to promote equity in health and improve provider-patient relationships

Oropharyngeal botryomycosis in a geriatric mare

Botryomycosis is an uncommon chronic bacterial infection that can have cutaneous and visceral involvement. This report describes an 18‐year‐old mixed‐breed mare presented with dysphagia, dyspnoea and an upper respiratory noise that developed secondary to oropharyngeal botryomycosis. Histological examination of the mass showed a granulomatous formation with Splendore–Hoeppli phenomenon surrounding Gram‐positive bacteria. This report describes the clinical signs, approach and management of an oropharyngeal Staphylococcus aureus granuloma in a geriatric mare.info:eu-repo/semantics/acceptedVersio

Bisphenol A and Bisphenol S Induce Endocrine and Chromosomal Alterations in Brown Trout

Bisphenol A is a widely used compound found in large amount of consumer products. As concerns have been raised about its toxicological and public health effect, the use of alternatives to bisphenol A are now increasing. Bisphenol S is one of the analogues being used as a replacement for bisphenol A despite the fact that little is known about the effects of bisphenol S on living organisms. In this study, we investigated the potential endocrine and genotoxic effects of bisphenol A and bisphenol S in juvenile brown trout (Salmo trutta). The fish were exposed to the compounds for either 2 weeks or 8 weeks via sustained-release cholesterol implants containing doses of 2 mg/kg fish or 20 mg/kg fish of the substances. The effects on the thyroid hormone levels and the estrogenic disrupting marker vitellogenin were evaluated, along with the genotoxic markers micronucleated cells and erythrocyte nuclear abnormalities. An increase in plasma vitellogenin was observed in fish exposed to the high dose of bisphenol A for 2 weeks. At this experimental time the level of the thyroid hormone triiodothyronine (T3) in plasma was elevated after bisphenol S exposure at the high concentration, and paralleled by an increase of micronucleated cells. Moreover, bisphenol A induced an increase of micronuclei frequency in fish erythrocytes after the exposure at the lowest dose tested. Taken together the results indicate that both bisphenol A and its alternative bisphenol S cause endocrine disrupting and genotoxic effects in brown trout, although suggesting two different mechanisms of damage underlying bisphenol A and bisphenol S activity

Metafísica de la debilidad y pedagogía del cuidado en Jean Vanier

En el presente artículo presentamos una investigación que se ha propuesto como objetivo analizar el concepto de debilidad así como el de pedagogía del cuidado en las experiencias y escritos de Jean Vanier. La obra y los proyectos de Vanier son fundamentales en la historia del pensamiento pedagógico europeo. Para ello se ha trabajado desde un enfoque metodológico de corte cualitativo y a través del análisis y la crítica documental. El estudio ha analizado tres grandes categorías que atraviesan el pensamiento y la praxis de Vanier: teorías sobre la debilidad, pedagogías del cuidado y pedagogía espiritual. El análisis se acompaña de una revisión biográfica del autor para poder situar su pensamiento de forma encarnada.In the present article we present a research that has been proposed as an objective to analyze the concept of weakness and the pedagogy of care in the experiences and writings of Jean Vanier. Vanier’s work and projects are fundamental in the history of European pedagogical thinking. To this end, a methodological and qualitative approach has been worked on through analysis and documentary criticism. The study has analyzed three major categories that go through Vanier’s thinking and praxis: Theories about Weakness, Pedagogies of Care and Spiritual Pedagogy. The analysis is accompanied by a biographical review of the author to be able to situate his thought in an embodied way

Shape variation analyzer: A classifier for temporomandibular joint damaged by osteoarthritis

We developed a deep learning neural network, the Shape Variation Analyzer (SVA), that allows disease staging of bony changes in temporomandibular joint (TMJ) osteoarthritis (OA). The sample was composed of 259 TMJ CBCT scans for the training set and 34 for the testing dataset. The 3D meshes had been previously classified in 6 groups by 2 expert clinicians. We improved the robustness of the training data using data augmentation, SMOTE, to alleviate over-fitting and to balance classes. We combined geometrical features and a shape descriptor, heat kernel signature, to describe every shape. The results were compared to nine different supervised machine learning algorithms. The deep learning neural network was the most accurate for classification of TMJ OA. In conclusion, SVA is a 3D Slicer extension that classifies pathology of the temporomandibular joint osteoarthritis cases based on 3D morphology
