Nuevos factores de riesgo para la progresión del Glaucoma
2015
INTRODUCCIÓN El Glaucoma es una neuropatía óptica de desarrollo progresivo que afecta a 90 millones de habitantes del planeta, siendo la forma clínica conocida como glaucoma primario de ángulo abierto (GPAA) la primera causa de ceguera irreversible en los países desarrollados. Los factores de riesgo para su desarrollo incluyen en primer lugar la presión intraocular, pero también la edad, la raza, la predisposición familiar, el espesor corneal central, miopía y presión de perfusión ocular han sido descritos como importantes en el desarrollo y/o progresión del glaucoma, entre otros. No obstante, hay evidencia acerca de la existencia de otros factores de riesgo, los denominados emergentes, así…
Orosensory Perception of Dietary Lipids in Mammals
2008
Obesity constitutes a major public health problem for the twenty-first century, with its epidemic spread worldwide, particularly in children. The overconsumption of fatty foods greatly contributes to this phenomenon. Rodents and humans display a spontaneous preference for lipid-rich foods. However, the molecular mechanisms underlying this pattern of eating behaviour in mammals remain unclear. The orosensory perception of dietary lipids was long thought to involve only textural and olfactory cues. Recent findings challenge this limited viewpoint, strongly suggesting that the sense of taste also plays a significant role in dietary lipid perception and might therefore be involved in the prefer…
New insights into submarine tailing disposal for a reduced environmental footprint: Lessons learnt from Norwegian fjords
2021
Submarine tailing disposal (STD) in fjords from land-based mines is common practice in Norway and takes place in other regions worldwide. We synthesize the results of a multidisciplinary programme on environmental impacts of STDs in Norwegian fjords, providing new knowledge that can be applied to assess and mitigate impact of tailing disposal globally, both for submarine and deep-sea activities. Detailed geological seafloor mapping provided data on natural sedimentation to monitor depositional processes on the seafloor. Modelling and analytical techniques were used to assess the behaviour of tailing particles and process-chemicals in the environment, providing novel tools for monitoring. To…
«Deberías adelgazar, te lo digo porque te quiero»: reflexiones autoetnográficas sobre la gordura
2021
La reciente construcción de una epidemia de obesidad global favorece que -además de ser estéticamente deseable- la delgadez se considere autoevidencia del estado de salud del individuo y marca de moralidad. En esta autoetnografía reflexiono sobre mi vivencia de ser gorda desde la infancia hasta la adultez, desde un enfoque sociológico feminista. La imposición cultural de la delgadez y la gordofobia alimentaron sentimientos de incapacidad, inadecuación corporal y sufrimiento psicológico que promovieron conductas alimentarias problemáticas. Mi argumento es que la guerra contra la obesidad opera en nombre de la salud, pero produce una renuncia significativa al bienestar físico y psicológico en…
Using exomarkers to assess mitochondrial reactive species in vivo
2014
Background:\ud The ability to measure the concentrations of small damaging and signalling molecules such as reactive oxygen species (ROS) in vivo is essential to understanding their biological roles. While a range of methods can be applied to in vitro systems, measuring the levels and relative changes in reactive species in vivo is challenging.\ud \ud Scope of review:\ud One approach towards achieving this goal is the use of exomarkers. In this, exogenous probe compounds are administered to the intact organism and are then transformed by the reactive molecules in vivo to produce a diagnostic exomarker. The exomarker and the precursor probe can be analysed ex vivo to infer the identity and a…

Linee guida in ortodonzia e attuale valutazione dei profili di responsabilitÃ
2016
Alla luce della nuova legge entrata in vigore in Italia, si discute il valore protettivo delle linee guida in ortodonzia sotto il profilo medico-legale. OBJECTIVES. In view of the Italian law recently come into force, this study aims at discussing the protective value of orthodontic guidelines in terms of legal medicine. MATERIALS AND METHODS. A review of orthodontic guidelines was conducted, including general orthodontic guidelines as well as specific guidelines for clinical and surgical cases. RESULTS AND CONCLUSIONS. Orthodontic practices envisaging professional liability include diagnosis, prevention, interception, care planning and treatment of all types of malocclusion (even when asso…
The Synbiotic Combination of Akkermansia muciniphila and Quercetin Ameliorates Early Obesity and NAFLD through Gut Microbiota Reshaping and Bile Acid…
2021
Gut microbiota plays a key role in obesity and non-alcoholic fatty liver disease (NAFLD), so synbiotics could be a therapeutic alternative. We aim to evaluate a nutritional intervention together with the administration of the bacteria Akkermansia muciniphila and the antioxidant quercetin in an in vivo model of early obesity and NAFLD. 21-day-old rats were fed with control or high-fat diet for six weeks. Then, all animals received control diet supplemented with/without quercetin and/or A. muciniphila for three weeks. Gut microbiota, NAFLD-related parameters, circulating bile acids (BAs) and liver gene expression were analyzed. The colonization with A. muciniphila was associated with less bod…
Integral geometry from Buffon to geometers of today
2016
La géométrie intégrale, aussi appelée théorie des probabilités géométriques, a accompagné pendant plus de deux siècles le développement des probabilités, de la théorie de la mesure et de la géométrie. Elle commence pour nous en 1777, date de la publication du « traité d'arithmétique morale » de Buffon. Ce n'est que presque un siècle plus tard que Crofton explicitera ce que veut dire mettre une mesure sur un ensemble continu comme l'ensemble des droites. Le sens de la formule de Cauchy-Crofton « la longueur d'une courbe plane est proportionnelle à la mesure pondérée de l'ensemble des droites qui la coupent », est maintenant clair. Au début du vingtième siècle, la géométrie intégrale commence…
