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…
Validation and biochemical characterisation of beneficial argan oil treatment in biomass propagation for industrial active dry yeast production
2019
Abstract Biomass propagation for the production of active dry yeasts (ADY) is an economically important industrial process where cellular oxidative stress significantly limits yield and fermentative capacity in the final product. Oxidative stress affects macromolecular cell components, such as lipid and proteins, thus impairing many different cellular processes. Its detrimental effect is prevented and alleviated by complex signalling, detoxifying and protein protecting systems, which can be induced by antioxidant treatments. Here we validate the general beneficial effect of argan oil treatment in bench-top simulations of industrial yeast biomass propagation as an effective technological str…
Contribution à la domestication de l'arganier pour la production de l'huile
2007
A survey conducted in 5 sites in the argan tree forest showed that argan oil represents an important part of the users' incomes. Nut-breaking is the most time-consuming and tedious step for the women involved in oil production. In 3 sites, the women were capable of distinguishing between those trees that yield nuts easy to break and trees yielding nuts difficult to break. These trees were named F and D, respectively. In each site, fruits were harvested from trees identified as F or D by the users, or at random. Those fruits were characterized by a set of measurements, including the force needed to break the nuts. Our measurements pointed out that the nuts harvested from F trees require a lo…
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…
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…
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…
Estudio estructural de la mucosa respiratoria post intubación orotraqueal
2012
La obstrucción vía aérea es la causa de muerte mas frecuente en el paciente politraumatizado. La intubación orotraqueal es la maniobra más eficaz para permeabilizar la via aérea siempre que la vía aérea superior sea permeable. La principal indicación de la intubación orotraqueal es la patología quirúrgica. La morbilidad asociada está en estrecha relación con los daños que ocasiona sobre la mucosa traqueal y con el tiempo de intubación. Hay muy pocos trabajos que han graduado el daño en la estructura traqueal post intubación a nivel histolopatológico y a nivel ultraestructural solo con microscopio electrónico de barrido. Material y métodos: Se han estudiado biopsias del tercio anterior de 2º…
Allium garganicum (Alliaceae), a new species from Apulia (SE Italy)
2009
Abstract A new endemic species of Allium, belonging to the A. stamineum Boiss. group, is described from the Mount Gargano (Apulia, SE Italy). This new taxon, named Allium garganicum, is the single representative of this group in the Italian flora, limited to a small population growing on the limestone rocks near the coast. Its relationships with allied taxa, A. stamineum Boiss. and A. guicciardii Heldr., are also discussed.
Preliminary report on the microvertebrate faunal remains from the Late Triassic locality at Krasiejów, SW Poland
2019
Fossil vertebrate remains from the Keuper unit in the vicinity of the village of Krasiejów have been analyzed for almost two decades. However, the main goal of these works was focused mainly on large vertebrates. Here the authors present the first description of microvertebrate fossils from that site. The collection of around 5,000 specimens is mainly comprised of teeth and scales. The most numerous remains belong to osteichthyans: dipnoans (Ptychoceratodus and cf. Arganodus), palaeoniscids, semionotids, redfieldiids and chondrichthyans, such as Lonchidion sp., which is the first indisputable record of that genus in the Upper Triassic of Poland and the first shark at the Krasiejów locality.…
Modulation of peroxisomes abundance by argan oil and lipopolysaccharides in acyl-CoA oxidase 1-deficient fibroblasts
2013
Pseudo-neonatal adrenoleukodystrophy (P-NALD) is a neurodegenerative disorder caused by acyl-CoA oxidase 1 (ACOX1) deficiency with subsequent impairment of peroxisomal fatty acid β-oxidation, accumulation of very long chain fatty acids (VLCFAs) and strong reduction in peroxisome abundance. Increase in peroxisome number has been previously suggested to improve peroxisomal disorders, and in this perspective, the present work was aimed at exploring whether modulation of peroxisomes abundance could be achieved in P-NALD fibroblasts. Here we showed that treatment with the natural Argan oil induced peroxisome proliferation in P-NALD fibroblasts. This induction was independent on activations of bo…
