Aplasia e hipoplasia del nervio auditivo : correlación anatómico-funcional
2014
La hipoacusia neurosensorial es uno de los problemas más frecuentes que afectan al recien nacido, llegando a afectar a entre 1,5 y 6 niños por cada 1000 recien nacidos vivos (Domínguez, 2011). Aunque la pérdida auditiva puede originarse en cualquier lugar de la vía auditiva es de todos conocido que la afectación más frecuente ya sea de causa congénita o adquirida se va a localizar a nivel coclear y en concreto a nivel de la célula ciliada. Estudios recientes sugieren que la disfunción del nervio auditivo (neuropatía auditiva) puede estar implicada hasta en el 1-10% de los casos de hipoacusia neurosensorial en niños, siendo menos frecuentes las pérdidas auditivas por alteración anatómica del…
Argan oil prevents down-regulation induced by endotoxin on liver fatty acid oxidation and gluconeogenesis and on peroxisome proliferator-activated re…
2015
In patients with sepsis, liver metabolism and its capacity to provide other organs with energetic substrates are impaired. This and many other pathophysiological changes seen in human patients are reproduced in mice injected with purified endotoxin (lipopolysaccharide, LPS). In the present study, down-regulation of genes involved in hepatic fatty acid oxidation (FAOx) and gluconeogenesis in mice exposed to LPS was challenged by nutritional intervention with Argan oil. Mice given a standard chow supplemented or not with either 6% (w/w) Argan oil (AO) or 6% (w/w) olive oil (OO) prior to exposure to LPS were explored for liver gene expressions assessed by mRNA transcript levels and/or enzyme a…
Efectos de la posición corporal y la sedación en la calidad de la voz
2015
En el ámbito de la Otorrinolaringología, existe una situación en donde la voz juega un papel importante para tomar una decisión intraoperatoria: durante la cirugía de tiroplastia de medialización de la cuerda vocal. Tras la realización de numerosas tiroplastias de medialización con anestesia local y sedación en nuestro Servicio de Otorrinolaringología, sospechamos que el test de voz intraoperatorio no era fiable ya que la voz obtenida durante el mismo no era la misma que la obtenida por el paciente al cabo de varios días de la intervención. Para tener una prueba objetiva de la fiabilidad o no del test de la voz hemos decidido realizar la comparación de la calidad de la voz del paciente en l…
Chemical composition of the essential oil from Thapsia garganica L. (Apiaceae) grown wild in Sicily and its antimicrobial activity.
2015
In this study, the chemical composition of the essential oil from flowers and leaves of Thapsia garganica L. collected in Sicily was evaluated by GC and GC-MS. The main components of T. garganica flower oil (T.f.) were chamazulene (58.3%), humulene oxide II (9.0%), tricosane (8.2%) and pentacosane (8.2%). Also the oil from leaves (T.l.) was characterised by high content of chamazulene (49.2%). Other abundant metabolites were 1,4-dimethylazulene (18.5%), (E)-phytol (6.3%) and neophytadiene (5.1%). The comparison with other studied oils of genus Thapsia is discussed. Antimicrobial activity against several micro-organisms, including some ones infesting historical art craft, was also determined.
An expeditious synthesis of spinasterol and schottenol, two phytosterols present in argan oil and in cactus pear seed oil, and evaluation of their bi…
2015
International audience; Spinasterol and schottenol, two phytosterols present in argan oil and in cactus pear seed oil, were synthesized from commercially available stigmasterol by a four steps reactions. In addition, the effects of these phytosterols on cell growth and mitochondrial activity were evaluated on 158N murine oligodendrocytes, C6 rat glioma cells, and SK-N-BE human neuronal cells with the crystal violet test and the MTT test, respectively. The effects of spinasterol and schottenol were compared with 7-ketocholesterol (71CC) and ferulic acid, which is also present in argan and cactus pear seed oil. Whatever the cells considered, dose dependent cytotoxic effects of 71CC were obser…
New data on the taxonomy of the endemic myomiminae (gliridae, rodentia) from the late miocene-early pliocene of gargano (southern Italy) with the des…
2009
The Late Miocene-Early Pliocene “Terre Rosse” vertebrate assemblages, found in the palaeokarst fissure fillings of the Apricena-Poggio Imperiale limestone quarries (North-Western side of the Gargano promontory, southern Italy), document a very long and complex history of endemic populations of a palaeoarchipelago. That history developed in at least four populating phases, which are characterised by changes in faunal diversity and include taxa with different degree of endemism. They have been subject of several studies since the beginning of the 1970s and deserve a particular attention for their evolutionary and palaeogeographical implications. The sampling of the “Terre Rosse” fissure filli…

El tratamiento personalizado de la insuficiencia velofaríngea mediante injerto adiposo autólogo de la faringe
2022
La incompetencia velofaríngea (IVP), definida por Lermoyez como un “desajuste anatómico y funcional entre el paladar blando y la faringe durante el habla”, es un problema funcional que requiere una gestión multidisciplinar con un estudio dinámico de las dos estructuras implicadas en el emisión de las palabras mediante la visión directa de los movimientos musculares durante la producción de fonemas. Varios estudios radiológicos han trabajado en la visualización dinámica del cierre velofaríngeo. Pigott fue el primero en introducir la nasofibroscopia en el estudio de la IVP. Ahora, el uso de la resonancia magnética funcional para el estudio del habla está en pleno desarrollo. Éste es un trabaj…
L’arganier et l’huile d’argane au Maroc : vers la mutation d’un système agroforestier traditionnel ?
2005
; Les formations ligneuses à arganiers (arganeraies) occupent environ 800 000 hectares au sud-ouest du Maroc. Dans ces zones semi-arides et arides, 1,3 million de personnes sont concernées par l’exploitation de systèmes agroforestiers traditionnels reposant sur l’arganier, arbre multi-usage. Mais en raison d’une surexploitation, ce milieu fragile est menacé. Depuis une quinzaine d’années, des efforts sont déployés pour définir les conditions d’un développement véritablement durable. Des travaux de recherche et de recherche-développement ont participé activement à des programmes dans ce sens. L’huile d’argane, produite à partir de l’amande oléagineuse des fruits de l’arganier, est certainem…
Nanotechnology for Natural Medicine: Formulation of Neem Oil Loaded Phospholipid Vesicles Modified with Argan Oil as a Strategy to Protect the Skin f…
2021
Neem oil, a plant-derived product rich in bioactives, has been incorporated in liposomes and hyalurosomes modified by adding argan oil and so called argan-liposomes and argan-hyaluro-somes. Argan oil has also been added to the vesicles because of its regenerative and protective effects on skin. In the light of this, vesicles were specifically tailored to protect the skin from oxidative stress and treat lesions. Argan-liposomes were the smallest vesicles (~113 nm); the addition of sodium hyaluronate led to an increase in vesicle size (~143 nm) but it significantly improved vesicle stability during storage. In vitro studies confirmed the free radical scavenging activity of formula-tions, irre…
