Impalement injury by glass shard with delayed colonic perforation

A 66-year-old man experienced a traumatic injury after a fall on top of a glass tea table, which caused some superficial lacerations all around the body. He was examined in the emergency room by a physician. The physician could not feel any foreign body upon wound exploration and sutured the laceration. Fourteen months after the injury, he developed progressive abdominal pain. On emergency room and abdominal x-ray showed a foreign body, which a CT scan revealed as an intraabdominal glass shard. The glass presumably impaled his abdominal wall as a result of his previous traumatic injury. The patient underwent laparotomy, which revealed a large glass  (16x1cm) perforating the transverse colon. It was extracted and the perforation closed with a lineal stapler. There was no need of bowel resection and the patient was discharged home nine days after the intervention

Architecture, Art and Technology in the Sanctuary of Our Lady of Arantzazu

In Spain, the architectural development of the fifties, is included within the second stage of autarky in the country favoured by US aid, loans from European banks for the purchase of goods, and the beginning of tourism expansion and improvement of external relations. In this context, the Basilica of Arantzazu was completed in 1954, a real turning point in the Spanish architectural historiography of the 20th century. Part of the archived documentation on this project has not been published yet, and will be showed for the first time in the paper of Congress, because it is interesting for the light it sheds on the construction process (real architecture, beyond considerations of architectural theory) of the Basilica of Arantzazu

NADPH oxidase 1 as a new regulator of the WNT pathway and the protective effect of vitamin D in colorectal cancer

Trabajo presentado en el 43rd Annual Meeting of the SEBBM, celebrado en Barcelona (España) del 19 al 22 de julio de 2021.Worldwide, colorectal cancer (CRC) is the third most common malignant neoplasm and the second leading cause of cancer-associated mortality, with an estimated increase in global prevalence of 60% by 2030 (1,2). Mutational inactivation of adenomatous polyposis coli (APC) is the hallmark of CRC and leads to an overactivation of WNT signaling that favors the development and progression of CRC (3). Large epidemiological studies suggest that the diabetic population is at increased risk for site-specific cancers, including CRC (4). Our laboratory has shown that hyperglycemia induces the accumulation of ROS in CRC but not healthy cells, driving the activation of a newly described ROS/AMPK/EP300 axis that enhances Wnt/b-catenin signaling. Increased EP300 leads to increased acetylation of β-catenin at K354, a requirement for nuclear accumulation and transcriptional activation of WNT target genes (5,6). The critical role driven by ROS suggest a possible involvement of the NADPH oxidases (NOX family, as a source of ROS. Specifically, NOX 1 and NOX 4 are expressed in colon epithelial cells, and their overexpression in CRC cells promotes cell proliferation and invasiveness (7,8,9,10). Our results indicate that hyperglycemia significantly increases NOX1 levels, in correlation with increased ROS production in CRC cells, suggesting a possible regulation of the ROS/ AMPK/EP300 axis by NOX1. Antioxidant mechanisms dealing with NOX1-induced ROS should be effective against CRC. Vitamin D (1α, 25-dihydroxyvitamin D3) is a powerful antioxidant that inhibits proliferation and promotes differentiation of CRC cells at least partially through inhibition of Wnt/β-catenin signalling. Consequently, vitamin D deficiency is associated with poor survival to CRC (11,12). Our results indicate that vitamin D causes a reduction in the levels and / or activity of some members of the NOX family by turning off the ROS/AMPK/EP300/β-catenin axis and its proliferative and tumorigenic effects. The data suggest a new antitumor mechanism of vitamin D linked to its anti-oxidant action. Our results integrate independent epidemiological links between vitamin D deficiency, diabetes and cancer in one overarching and unifying mechanism

De la gran urbe a la modesta villa: aplicación de la prospección magnética a la arqueología romana

La caracterización de yacimientos arqueológicos es una de las aplicaciones más extendidas de la prospección magnética, por su carácter no invasivo, que permite explorar sin destruir superficies de extensión considerable, y debido al carácter ferromagnético de muchos elementos asociados a la actividad humana (instrumentos de hierro, componentes minerales de tejas, ladrillos, hornos de cocción, etc...). Habitualmente, en prospección magnética se mide la intensidad total del campo magnético terrestre (realizando las correcciones de las oscilaciones debidas a la variación diurna y las micropulsaciones) y el gradiente horizontal o vertical (diferencia entre las medidas tomadas simultáneamente en posiciones cercanas mediante dos sensores, ver figura 1), que resulta muy útil cuando se trata de detectar anomalías debidas a cuerpos cercanos a la superficie. Frente a la sistemática de trabajo en prospecciones geológicas, el mallado de la prospección magnética en arqueología suele ser muy denso, con 1 m o 0,5 m de espaciado entre perfiles en muchas ocasiones

Modeling Ecosystems Using P Systems: The Bearded Vulture, a Case Study

The Bearded Vulture (Gypaetus barbatus) is an endangered species in Europe that feeds almost exclusively on bone remains of wild and domestic ungulates. In this paper, we present a model of an ecosystem related to the Bearded Vulture in the Pyrenees (NE Spain), by using P systems. The evolution of six species is studied: the Bearded Vulture and five subfamilies of domestic and wild ungulates upon which the vulture feeds. P systems provide a high level computational modeling framework which integrates the structural and dynamic aspects of ecosystems in a comprehensive and relevant way. P systems explicitly represent the discrete character of the components of an ecosystem by using rewriting rules on multisets of objects which represent individuals of the population and bones. The inherent stochasticity and uncertainty in ecosystems is captured by using probabilistic strategies. In order to experimentally validate the P system designed, we have constructed a simulator that allows us to analyze the evolution of the ecosystem under different initial conditions.Ministerio de Educación y Ciencia TIN2006-13425Junta de Andalucía TIC-58

Orphan crops of archaeology-based crop history research

So-called ‘forgotten’ or ‘orphan’ crops are an important component of strategies aimed at preserving and promoting biodiversity. Knowledge of historical cultivation, usage, and geographic and evolutionary trajectories of plants, that is, crop history research, is important for the long-term success of such efforts. However, research biases in the crops chosen for study may present hurdles. This review attempts to systematically identify patterns in crop species representativeness within archaeology-based crop history research. A meta-analysis and synthesis of archaeo- botanical evidence (and lack thereof) is presented for 268 species known to have been cultivated for food prior to 1492 CE from the Mediterranean region to South Asia. We identified 39 genera with known crop plants in this geographical and histor- ical context that are currently absent from its archaeobotanical record, constituting ‘orphan’ crops of archaeobotany. In addition, a worldwide synthesis of crop species studied using geometric morphometric, archaeogenetic and stable isotope analyses of archaeological plant remains is presented, and biases in the species represented in these disciplines are discussed. Both disciplinary methodological biases and economic agenda-based biases affecting species representativeness in crop history research are apparent. This study also highlights the limited geographic diffusion of most crops and the potential for deeper historical perspectives on how crops become marginal- ized and ‘forgotten’
