Sur les traces du mouton en Gaule
2005
Concerning the evidence for sheep in Gaul.- In northern Gaul, bones of sheep and goat are found in most Iron Age sites, farms, villages, graves and shrines. It is difficult to establish a good distinction between the bones of these two species, but sheep are more numerous than goat. This short paper deals with the use of these animals in domestic and ritual practices over a long period, from the Late Bronze Age to the beginning of Roman period. The fact that these animals are represented by bones encourages the study of meat consumption. Mutton is consumed in domestic contexts, but it is also offered during banquets in shrines, public areas in villages or other places, and plays a role duri…
Production, oxidation traits and health of dairy ewes fed diets supplemented with fungus myceliated grains.
2019
Mushrooms contain many bioactive compounds, mainly poly- and oligosaccharides, known to have benefits for human health. Polysaccharides from mushrooms exhibited immunomodulatory, antibacterial, antiviral, and antifungal properties, as well as antitumor activity. Furthermore, some mushrooms showed to have potent antioxidant properties due to the presence of phenolic acids, flavonoids, polysaccharides, carotenoids, ascorbic acid, and tocopherols. These beneficial properties of mushrooms bioactive compounds indicate their potential use as performance-enhancing natural feed additives for livestock animals. In this regard, the use of mushrooms and mushroom-derived products has largely been inves…
Les restes animaux de la nécropole de Povegliano-Ortaia (IIe-Ier siècle avant notre ère)
2012
International audience; Plus d'un millier de restes animaux ont été recueillis dans vingt-deux inhumations, dix-sept crémations et six sépultures au rite indéterminé. Deux espèces se distinguent par leur fréquence, le porc et la volaille. Le bœuf et les caprinés sont moins fréquents, alors que le cheval, le chien, l'oie et l'ours sont rares. La plupart des porcs sont très jeunes, avec notamment des sujets périnataux. Ils sont souvent déposés sous forme d'épaules, de jambons ou de séries de côtes. La volaille est souvent représentée par des squelettes, tous les sujets dont le sexe a pu être déterminé sont des poules, la plupart adultes.Dans les incinérations, le porc (80 %) et la volaille (1…
Factors associated with milk urea concentrations in Girgentana goats
2010
A total of 1,481 milk samples of 166 Girgentana goats, taken along the entire lactation, were utilised to evaluate the effect of non nutritional factors on milk urea (MU). Parity, stage of lactation and month of sampling significantly influenced MU, while no effect was found for born kids number. The first kidding goats produced lower MU than multiparous goats. Trend of MU was similar to milk production course with a peak found at 60 DIM. The different MU levels between several months of production are often linked to pasture chemical variations.
A luminal glycoprotein drives dose-dependent diameter expansion of the Drosophila melanogaster hindgut tube
2012
An important step in epithelial organ development is size maturation of the organ lumen to attain correct dimensions. Here we show that the regulated expression of Tenectin (Tnc) is critical to shape the Drosophila melanogaster hindgut tube. Tnc is a secreted protein that fills the embryonic hindgut lumen during tube diameter expansion. Inside the lumen, Tnc contributes to detectable O-Glycans and forms a dense striated matrix. Loss of tnc causes a narrow hindgut tube, while Tnc over-expression drives tube dilation in a dose-dependent manner. Cellular analyses show that luminal accumulation of Tnc causes an increase in inner and outer tube diameter, and cell flattening within the tube wall,…
Practices in research, surveillance and control of neglected tropical diseases by One Health approaches: A survey targeting scientists from French-sp…
2021
One health (OH) approaches have increasingly been used in the last decade in the fight against zoonotic neglected tropical diseases (NTDs). However, descriptions of such collaborations between the human, animal and environmental health sectors are still limited for French-speaking tropical countries. The objective of the current survey was to explore the diversity of OH experiences applied to research, surveillance and control of NTDs by scientists from French-speaking countries, and discuss their constraints and benefits. Six zoonotic NTDs were targeted: echinococcoses, trypanosomiases, leishmaniases, rabies, Taenia solium cysticercosis and leptospiroses. Invitations to fill in an online q…
Efecto de frecuencias cardiacas suprafisiológicas en el miocardio sometido a isquemias de distinta duración
2013
La hipótesis de partida de la presente Tesis Doctoral fue: "El efecto que sobre la función del ventrículo izquierdo produce una frecuencia cardiaca suprafisiológica tras un episodio de isquemia miocárdica depende de la duración y/o repetición de dicha isquemia." Para comprobar la hipótesis de trabajo se marcaron los siguientes objetivos: 1) Objetivo principal: el estudio de las alteraciones de la función ventricular izquierda en un modelo animal de sobreestimulación ventricular precedida por diferentes protocolos de isquemia-reperfusión. 2) Objetivos secundarios: a) Comprobar si una sobreestimulación ventricular de dos horas de duración, a una frecuencia un 60% superior a la inicial, es cap…
Il linguaggio degli uccelli: Aristotele e lo specifico fonetico del linguaggio umano
1996
A partire da Pagliaro e Belardi, padri fondatori degli studi italiani di fonetica greca, prevale la convinzione che lo specifico del linguaggio umano non si trovi su base fonetica. Spcifico del linguaggio sarebbe 'non la fonicità nè l'articolazione ma la funzione simbolica. Attraverso l'analisi minuziosa delle opere di Aristotele, il contributo si propone di sfatare questo mito. L'analisi è condotta sul linguaggio degli uccelli, in confronto al linguaggio fonetico umano. Il risultato è che, per quanto gli uccelli siano capaci come gli uomini di produrre voce articolata (dialektos) è questo è importanti a livello di continuità fra le specie e come smentita dell'antropocentrismo, il linguaggi…
Effect of propylene glycol on pre- and post-partum performance by dairy ewes
2005
This study was carried out in order to determine the effects, after feeding propylene glycol to Valle del Belice ewes 30 days prepartum and 30 days postpartum, on metabolic profiles, body-condition score, milk yield, milk composition, milk clotting ability and the performance of suckling lambs. Ewes were blocked by parity, body-condition score and previous milk production, and assigned randomly to either a control diet or a diet containing propylene glycol fed at the rate of 80 g/ewe/day (low PG) or 160 g/ewe/day (high PG). Feeding propylene glycol prepartum decreased the concentration of BHBA and NEFA and increased the concentration of glucose in the ewes’ plasma. Milk yield from ewes fed …
The histone acetyltransferase MOF activates hypothalamic polysialylation to prevent diet-induced obesity in mice
2014
Overfeeding causes rapid synaptic remodeling in hypothalamus feeding circuits. Polysialylation of cell surface molecules is a key step in this neuronal rewiring and allows normalization of food intake. Here we examined the role of hypothalamic polysialylation in the long-term maintenance of body weight, and deciphered the molecular sequence underlying its nutritional regulation. We found that upon high fat diet (HFD), reduced hypothalamic polysialylation exacerbated the diet-induced obese phenotype in mice. Upon HFD, the histone acetyltransferase MOF was rapidly recruited on the St8sia4 polysialyltransferase-encoding gene. Mof silencing in the mediobasal hypothalamus of adult mice prevented…
