La historia de la dinastía en imágenes : Martín el Humano y el rollo genealógico de la Corona de Aragón
2002
Este artículo estudia el rollo genealógico de la Corona de Aragón conservado hoy en la biblioteca del monasterio de Poblet. La obra debió ser encargada por el rey Martín el Humano (1396-1410) para conmemorar a sus predecesores en el trono y, probablemente, servir de ejemplo a su hijo y presunto sucesor, Martín el Joven, rey de Sicilia, antes de su muerte, acaecida en 1409. El autor analiza el carácter de las imágenes reales pintadas en el pergamino, con el fin de precisar el significado político y cultural del rollo en relación con textos históricos y otros manuscritos iluminados que pueden vincularse a la corte durante el reinado de Martín el Humano. Las imágenes de los antiguos reyes de A…
Effect of Breed and Diet Type on the Freshness and Quality of the Eggs: A Comparison between Mos (Indigenous Galician Breed) and Isa Brown Hens
2020
Eggs are a nutritious food, offering a balanced source of essential amino and fatty acids, minerals, and vitamins. Genetic and diet factors can modify hen egg traits. Thus, the effects of breed and feed on egg quality using two laying hens, Mos (autochthonous breed) and Isa Brown (commercial hybrid), and three feeds, commercial fodder (CF), corn/pea/triticale (CPT) and corn/wheat (CW), were investigated. Freshness parameters (egg weight, eggshell weight and thickness, albumen height, Haugh units and yolk color), chemical composition, color and textural parameters, as well as fatty acid profile, were assessed on a total of 288 eggs, from the two breeds. The samples were divided in 96 eggs, c…
Empirical calibration of the clumped isotope paleothermometer using calcites of various origins
2014
We present the first universal calibration of the clumped isotope thermometer for calcites of various mineralizing types. These are an eggshell of an ostrich, a tropical bivalve, a brachiopod shell, cold seep carbonate, and three foraminifera samples that grew between 9 and 38 C. CaCO3 was digested at 90 C using a common acid bath. Considering a difference in phosphoric acid fractionation factors between reaction at 25 and 90 C of 0.069& (Guo et al., 2009), the function between growth temperature T and the excess of 13 C– 18 O bonds in the evolved CO2 is expressed by a linear regression between 1/T 2 and absolute D47 (R 2 = 0.9915):

Distribution of Albian clastic deposits in the Benguela basin (Angola): evidence of a Benguela palaeocurrent?
2009
Abstract The Albian clastic Tuenza Formation of the Benguela basin (south Angola) is described and its geographic distribution analysed in detail. From these observations, the existence of an Albian “PalaeoBenguela current” is proposed. This would imply that a marine longshore current reworked the sand transported by palaeorivers and settled it northward along the coast of the young Atlantic Ocean (during the Albian). A parallel between Albian clastic deposits and the modern sediments deposited by the Benguela current is drawn, focusing on the striking resemblance between the two currents, i.e. the actual Benguela current and the Albian marine current, and the associated sedimentary bodies.
The Effectiveness of Glutathione Redox Status as a Possible Tumor Marker in Colorectal Cancer
2021
The role of oxidative stress (OS) in cancer is a matter of great interest due to the implication of reactive oxygen species (ROS) and their oxidation products in the initiation of tumorigenesis, its progression, and metastatic dissemination. Great efforts have been made to identify the mechanisms of ROS-induced carcinogenesis
Age-related changes in antioxidant defence mechanisms and peroxidation in isolated hepatocytes from spontaneously hypertensive and normotensive rats
1994
International audience; The effects of age and hypertension on the antioxidant defence systems and the lipid peroxidation in rat isolated hepatocytes were studied. Four different age groups (1, 3, 6 and 12 months) were considered in spontaneously hypertensive rats (SHR) and normotensive Wistar-Kyoto (WKY) rats. Age-associated changes were observed on vitamin E status, glutathione (GSH) level, MDA formation and glutathione peroxidase (GSH-Px) activity in both strains. Maximal levels or activities of these parameters were found at 3 and 6 months, except for MDA which was low at 3 months. Then, a fall was observed at 12-month-old compared to 6-month values. In addition, GSH-Px activity was sig…
Redox signaling in acute pancreatitis
2015
Acute pancreatitis is an inflammatory process of the pancreatic gland that eventually may lead to a severe systemic inflammatory response. A key event in pancreatic damage is the intracellular activation of NF-κB and zymogens, involving also calcium, cathepsins, pH disorders, autophagy, and cell death, particularly necrosis. This review focuses on the new role of redox signaling in acute pancreatitis. Oxidative stress and redox status are involved in the onset of acute pancreatitis and also in the development of the systemic inflammatory response, being glutathione depletion, xanthine oxidase activation, and thiol oxidation in proteins critical features of the disease in the pancreas. On th…
Tang dynasty (618-907) bowl measured with PIXE
2017
Brownish bowl originating from an underwater shipwreck located near Belitung island in the Java Sea, some 600 km south-east from Singapore, has been measured with particle induced X-ray emission. This study was a pilot project for the – now a spin-off company – Recenart research team where one target was to evaluate the authenticity of the different type of art objects. PIXE measurements were done from three different material positions from a single bowl received from a customer. These locations were categorized as a bluish/greenish pigment (under glaze), thick glaze and the body clay. When the obtained data was compared to the other references from different dynasties and kiln sites, the …
Iconography and monumental art in "feodal space" from the 10th to the 12th century : the depiction of the Three Kings and its spread
2012
This dissertation deals with the iconography of the Three Kings from the Xth to the XIIth century, by means of a study of its adaptation on monumental decoration in Latin Europe, so as to unravel how it was adapted by feudal society. In order to do so, the first question is that of the new royal status acquired in the Xth century by the Magi from the Gospel of Matthew, analyzed thanks to the concept of “ruler figure” that emerged at the time and was depicted by Marc Bloch in Les Rois thaumaturges (1924) and Ernst Kantorowicz in the The King’s Two Bodies (1957). The aim is to define where the newly defined Three Kings stand in the intricate network of “ties between man and man” theorized by …
