Quelques observations récentes sur des sites de l'Antiquité tardive à Autun (2001-2008)
2011
This article describes the result of ten or so fairly limited preventive archaeology operations (surveillance of works, diagnostics not followed up with excavations) carried out over the last ten years that have nonetheless finalised knowledge of several deposits from Late Antiquity in Autun located intra muros but also outside the walls. The works have enabled us to renew our knowledge of the reduced enclosure and of three Late Antiquity necropolises, to discover the remains of a lime kiln from the end of the 4th century at the centre of a public zone (perhaps the forum), and lastly to point up the difficulties of interpretation of an occupation of two zones from the end of the 4th century…
Estudio experimental comparado de marcadores bioquímicos en la infección por Fasciola hepatica y F. gigantica
2017
Fascioliasis is caused by the genetically and phenotypically very close Fasciola hepatica and F. gigantica. The latter, always considered secondary in human infection, appears nowadays increasingly involved in human endemic areas of Africa and Asia. Unfortunately, little is known about the pathogenicity of this liver fluke species, mainly due to difficulties assessing the moment of a patient's infection in the anamnesis and in the differential diagnosis with F. hepatica. This is the first experimental study comparing F. hepatica and F. gigantica in a long-term study of up to 24 weeks with genotypically and phenotypically standardised fluke strains in the same animal model host, the Guirra s…
Una revisión crítica del debate sobre las necesidades humanas desde el enfoque centrado en la persona
2012
El artículo presenta algunos de los diferentes modelos teórico-explicativos sobre las necesidades humanas; revisa el estado del arte en las publicaciones recientes, y evalúa críticamente las limitaciones y potenciales que ellas tienen, desde una mirada sistémica y fenoménica desde un enfoque centrado en la persona. L’article présente certains des différents modèles théorico-explicatifs sur les besoins humains; il expose un état des lieux de la bibliographie récente, et évalue de manière critique les limites et potentiels que celles-ci peuvent représenter, dans une perspective systémique et propre au phénomène centrée sur la personne. The article presents some of the different theoretical-ex…
Motivations for business start-up: are there any differences between disabled and non-disabled people?
2014
Masteroppgave i økonomi og administrasjon – Universitetet i Agder 2014 This master‟s thesis seeks to investigate whether motivations for business start-up between persons with and without disabilities differ. The motivation for this study is that, disabled entrepreneurs may have unique reasons which need the attention of all stakeholders who advocate for equal human rights. The study uses a unique sample of 273 from Ecuadorian micro-bank. The findings indicate that persons without disabilities are more materialistic than persons with disabilities. Materialism relates to opportunity-driven entrepreneurship where individuals start business as a result of available market opportunities. The re…
Resting State EEG Directed Functional Connectivity Unveils Changes in Motor Network Organization in Subacute Stroke Patients After Rehabilitation
2022
Brain plasticity and functional reorganization are mechanisms behind functional motor recovery of patients after an ischemic stroke. The study of resting-state motor network functional connectivity by means of EEG proved to be useful in investigating changes occurring in the information flow and find correlation with motor function recovery. In the literature, most studies applying EEG to post-stroke patients investigated the undirected functional connectivity of interacting brain regions. Quite recently, works started to investigate the directionality of the connections and many approaches or features have been proposed, each of them being more suitable to describe different aspects, e.g.,…
The influence of blue light on the Dionaea muscipula cultivation
2018
Rośliny wykorzystują światło jako źródło energii do fotosyntezy, reagują na jego intensywność, długość fali świetlnej i kierunek światła. Jest ono także swoistym sygnałem środowiskowym. Światło jest odbierane przez fotoreceptory roślin, takie jak: kryptochromy, fototropiny oraz fitochromy, a rośliny generują szeroki zakres specyficznych odpowiedzi fizjologicznych przez te receptory. Do badań wykorzystano dwie hodowle roślinne składające się z dwóch odmian muchołówki amerykańskiej - Dionaea muscipula: Regular form oraz Red green. Jedną z hodowli poddano oddziaływaniu światła niebieskiego, a drugą - kontrolną prowadzono w warunkach oddziaływania światła słonecznego. Prowadzono pomiary morfolo…
Papel del grosor íntima-media en carótida y del TC de coronarias en la detección temprana de aterosclerosis en la mujer y posible modulación por poli…
2016
La enfermedad cardiovascular es una de las primeras causas de muerte . Su fundamento biológico es la aterosclerosis, un proceso inflamatorio. Una parte de la lucha contra ella se ha centrado en la actuación sobre los factores de riesgo modificables. Paralelamente, hay un interés creciente en la detección de biomarcadores fiables, que sean capaces de identificar la presencia de aterosclerosis en fases tempranas, cuando el riesgo clínico es bajo. Las pruebas de imagen están siendo importantes en este contexto. Aunque ha sido tradicionalmente asociada con el género masculino, la enfermedad cardiovascular también representa la principal causa de morbi-mortalidad en las mujeres. De hecho, cualqu…
Assessment of Gully Erosion Susceptibility Using Multivariate Adaptive Regression Splines and Accounting for Terrain Connectivity
2017
In this work, we assessed gully erosion susceptibility in two adjacent cultivated catchments of Sicily (Italy) by employing multivariate adaptive regression splines and a set of geo-environmental variables. To explore the influence of hydrological connectivity on gully occurrence, we measured the changes of performance occurred when adding one by one nine predictors reflecting terrain connectivity to a base model that included contributing area and slope gradient. Receiver operating characteristic (ROC) curves and the area under the ROC curve were used to evaluate model performance. Gully predictive models were trained in both the catchments and submitted to internal (in the calibration cat…
Progestogens and risk of breast cancer: a link between bone and breast?
2015
This article reviews the data supporting the role of receptor activator of the nuclear factor kappa (RANK) and its ligand, RANKL, in progestogen-induced breast cancer. Both experimental and clinical studies have been included. The expression of both RANK and RANKL has been described in epithelial cells of both mice and humans. Experiments of gain and loss of function in mice have shown that RANK/RANKL mediate alveologenesis during pregnancy or the estrous cycle. Moreover, the participation of the RANK/RANKL has been detected in models of breast carcinogenesis associated with progestogens-like medroxyprogesterone acetate. Recent clinical studies have found that the expression of RANK is asso…
Anti-senescence and Anti-inflammatory Effects of the C-terminal Moiety of PTHrP Peptides in OA Osteoblasts.
2016
Osteoarthritis (OA) is characterized by degenerative changes in the whole joint leading to physical disability in the elderly population. This condition is associated with altered bone metabolism in subchondral areas suggesting that therapeutic strategies aimed at modifying bone cell metabolism may be of interest. We have investigated the effects of several parathyroid hormone-related protein (PTHrP)-derived peptides (1-37): (N-terminal), (107-111) and (107-139) (C-terminal) on senescence features induced by inflammatory stress in human OA osteoblasts. Incubation of these primary cells with interleukin(IL)-1β led to an increased expression of senescence markers senescence-associated-β-galac…
