Steerable wavelet transform for atlas based retinal lesion segmentation
2013
International audience; Computer aided diagnosis and follow up can help in prevention and treatment of diabetes and its related complications. Screening of diabetes related disease in the eyes is done by a special low cost fundus camera. A follow up of the patients visiting at di fferent time intervals for screening brings us to the problem of image analysis for change detection and its cost per patient. It is very likely that human annotations for the lesions may be erroneous and often time consuming. Since the ethnic background plays a signi cant role in retinal pigment epithelium, visibility of the choroidal vasculature and overall retinal luminance in patients and retinal images, an eth…
An Intracortical Implantable Brain-Computer Interface for Telemetric Real-Time Recording and Manipulation of Neuronal Circuits for Closed-Loop Interv…
2021
Recording and manipulating neuronal ensemble activity is a key requirement in advanced neuromodulatory and behavior studies. Devices capable of both recording and manipulating neuronal activity brain-computer interfaces (BCIs) should ideally operate un-tethered and allow chronic longitudinal manipulations in the freely moving animal. In this study, we designed a new intracortical BCI feasible of telemetric recording and stimulating local gray and white matter of visual neural circuit after irradiation exposure. To increase the translational reliance, we put forward a Göttingen minipig model. The animal was stereotactically irradiated at the level of the visual cortex upon defining the targe…

Influence du court noué sur la diversité fonctionnelle des champignons mycorhiziens à arbuscules dans des racines et du sol de vigne
2022
Le court-noué (CN) correspond à un dépérissement infectieux (népovirus) qui apparaît par taches au sein des parcelles. Cette maladie entraîne une dégénérescence progressive de la vigne qui conduit in fine à la mort des ceps. A l’heure actuelle, environ 60% du vignoble national serait touché, dont 30% de façon importante. Seize népovirus sont responsables de dégénérescence ou de dépérissement de la vigne. Cependant, le Grapevine FanLeaf Virus (GFLV) est le principal agent responsable. Il est transmis spécifiquement de plante à plante par un nématode ectoparasite du sol, Xiphinema index. Les nématodes, en piquant successivement deux ceps voisins dont les racines sont proches, inoculent le vir…
Epigenetic profile of developmentally important genes in bovine oocytes
2011
Assisted reproductive technologies are associated with an increased incidence of epigenetic aberrations, specifically in imprinted genes. Here, we used the bovine oocyte as a model to determine putative epigenetic mutations at three imprinted gene loci caused by the type of maturation, either in vitro maturation (IVM) in Tissue Culture Medium 199 (TCM) or modified synthetic oviduct fluid (mSOF) medium, or in vivo maturation. We applied a limiting dilution approach and direct bisulfite sequencing to analyze the methylation profiles of individual alleles (DNA molecules) for H19/IGF2, PEG3, and SNRPN, which are each associated with imprinting defects in humans and/or the mouse model, and are k…
ROLE OF THE ISWI CHROMATIN REMODELER FACTOR IN TISSUE REGENERATION
2014
Durante lo sviluppo degli organismi multicellulari, le modifiche epigenetiche della cromatina garantiscono l’attuazione dei programmi trascrizionali che guidano i processi di determinazione del destino cellulare. La presenza di modifiche epigenetiche della cromatina inoltre, assicura il mantenimento e la propagazione, nel corso delle divisioni mitotiche, di una memoria epigenetica cellulare. Tuttavia, sono note almeno due eccezioni a questo processo: la rigenerazione e la transdeterminazione Durante la rigenerazione tissutale, un fenomeno evolutivamente molto conservato, cellule già determinate affrontano cicli di proliferazione durante i quali possono riprogrammare la loro memoria epigenet…
Carotenoid bioaccessibility in pulp and fresh juice from carotenoid-rich sweet oranges and mandarins.
2015
Citrus fruits are a good source of carotenoids for the human diet; however, comparative studies of carotenoids in different citrus food matrices are scarce. In this work the concentration and bioaccessibility of carotenoids in sweet oranges and mandarins with marked differences in carotenoid composition were evaluated in pulp and compared to those in fresh juice. The pulp and juice of the red-fleshed Cara Cara sweet orange variety was highly rich in carotenes (mainly lycopene and phytoene) compared to standard Navel orange, while β-cryptoxanthin and phytoene predominated in mandarins. Total carotenoid content in the pulp of the ordinary Navel orange and in the red-fleshed Cara Cara orange, …

Pintura califal de Bédar (Almería, 355/966)
2020
Esta investigación se centra en un texto árabe pintado sobre un elemento inusual: una balsa de agua para riego en Bédar (Almería). Junto al epígrafe que la data, hay dibujados dos animales cuadrúpedos que quizá representen una escena de caza y una cenefa decorativa; conserva asimismo otros signos gráficos y diseños muy degradados que no ha sido posible descifrar totalmente. Como hasta ahora no se había determinado su cronología, en este estudio he seguido el método habitual en Epigrafía Árabe: dibujar los trazos visibles y restituir después las partes de pintura desaparecida o muy borrada. Como resultado de este estudio queda de relieve el valor de este destacado documento de la cultura pop…
