This work is concerned with the design of two different analog channels for hybrid and monolithic pixels readout in view of applications to the SVT at the SuperB Factory. The circuits have been designed in a 130nm CMOS, vertically integrated technology, which, among others, may provide some advantages in terms of functional density and electrical isolation between the analog and the digital sections of the front-end

Comunicación, semillas para la integración

Esta Tesis llamada “Comunicación, semillas para la integración” se desarrolló en el ámbito del Instituto de Investigación y Desarrollo Tecnológico para la Pequeña Agricultura Familiar (IPAF), que pertenece al Instituto Nacional de Tecnología Agropecuaria (INTA) Para cumplir nuestra meta nos propusimos “conocer e indagar la realidad comunicacional del IPAF pampeano para analizar sus estrategias comunicacionales con el fin último de realizar un Plan de Comunicación consecuente con el PEI 2005- 2015”. De esta idea general surgieron tres objetivos; en primer lugar analizar la comunicación interna y externa de la institución, lo que implicó tomar contacto con sus miembros y vincularnos con la organización en sí. El segundo objetivo consistió en evaluar si los miembros de la institución conocían los aspectos más relevantes del Discurso Identitario. El último objetivo residió en analizar los procesos de gestión del IPAF. Al considerar el abordaje comunicacional - institucional que se plantea mediante las líneas de acción, buscamos enriquecer los lazos de comunicación del IPAF y contribuir a su labor de promover la agricultura familiar; de esta manera, comprendemos y damos a entender que la razón de ser del instituto es el pequeño agricultor familiar, plasmado como figura central en la presente tesis.Facultad de Periodismo y Comunicación Socia

Human equilibrative nucleoside transporter 1 (hENT1) levels predict response to gemcitabine in patients with biliary tract cancer (BTC)

Background and aim: Translational data suggest that nucleoside transporters, in particular human equilibrative nucleoside transporter 1 (hENT1), play an important role in predicting clinical outcome after gemcitabine chemotherapy for several types of cancer. The aim of this study was to retrospectively determine patients' outcome according to the expression of hENT1 in tumoral cells of patients receiving gemcitabine-based therapy. Materials and Methods: The immunohistochemistry analysis was performed on samples from thirty-one patients with unresectable biliary tract cancer (BTC) consecutively treated with first line gemcitabine-based regimens. Results: Positive hENT1 staining patients were 21 (67.7%); negative hENT1 staining patients were 10 (32.3%). Statistical analysis revealed no association between baseline characteristics, toxicities and tumor response to gemcitabine and hENT1 levels. In the univariate analysis, HENT1 expression was significantly correlated with time to progression (TTP) (p=0.0394; HR 2.902, 95%CI 1.053-7.996). The median TTP was 6.33 versus 2.83 months, respectively in patients with positive versus negative hENT1 staining. Moreover, patients with positive hENT1 expression showed a longer median overall survival when compared with patients with low hENT1 expression (14 versus 7 months, respectively), but this difference did not reach the statistical significance (p=0.128). Conclusions: Therefore, hENT1 may be a relevant predictive marker of benefit from gemcitabine-based therapies in patients with advanced BTC. © 2011 Bentham Science Publishers Ltd

Updating the National Baseline of Non-Indigenous Species in Spanish Marine Waters

The introduction of new non-indigenous species (NIS) in Spanish marine waters is addressed under Descriptor 2 of the European Union’s Marine Strategy Framework Directive. National baseline inventories of NIS have been compiled and updated for the three subregions (Western Mediterranean Sea, WMED; Bay of Biscay–Iberian Coast, ABI; Macaronesia, AMA) with data from 1800 to 2021. An overall of 574 species were identified with an alien, cryptogenic, crypto-expanding, or debatable status, mostly invertebrates (~65%) and primary producers (~22%). Of 412 alien species, 80.51% were reported in ABI, 67.82% in WMED, and 66.67% in AMA. Cryptogenic species are more abundant in the WMED (25.25%), compared to AMA (19.77%) and ABI (18.46%). ABI harbors more established species (62.56%) than AMA (45.2%) and WMED (43.56%), contrary to casual records (AMA 31.64%, WMED 23.76%, ABI 13.85%). Invasive species are more abundant (14.36%) in WMED. The ‘transport-stowaway’ pathway accounted for 142 (79.33%), 123 (67.58%), and 169 (85.21%) records in WMED, ABI, and AMA, respectively. The second most common pathway was ‘transport-contaminant’ related to mariculture (~10% of the total), prevalently in ABI with 42 species (23.08%). The Canary Islands stand out for species introduced through oil platforms from throughout the world. ‘Unaided’ was a relevant pathway of secondary introduction into the WMED, particularly of Lessepsian species progressing westwards. Temporal trends in newly introduced species show similar behavior among subregions.This research was funded by Ministerio para la Transición Ecológica y el Reto Demográfico, grant number 11_MM_ESMARES2.

Соотношение токсичности и преимуществ использования бевацизумаба при метастатическом раке толстой кишки: метаанализ рандомизированных клинических испытаний

Проведен систематический обзор и метаанализ, изучающий использование бевацизумаба (Бев) при метастатическом колоректальном раке. В анализ включены данные исследований, в которых принимали участие 3385 пациентов. Первичной конечной точкой была безопасность терапии, вторичными конечными точками — общая выживаемость и выживаемость без прогрессирования заболевания. Относительные риски (ОР) для побочных эффектов расчитывали с 95% доверительным интервалом (ДИ), с использованием метода обратной дисперсии. Для статистически значимых ОР определяли число обследуемых, которых необходимо дополнительно включить в группу Бев для нанесения вреда одному дополнительному пациенту в сравнении с контролем (number needed to harm — NNH). Значимое повышение ОР наблюдалось только для гипертензии (относительный риск 2,98, 95% ДИ 2,32–3,84), гастроинтестинальных перфораций (5,04, 95% ДИ 1,72–14,79) и кровотечений (2,07, 95% ДИ 1,19–3,62). Бев значимо улучшал как общую (ОР 0,80, 95% ДИ 0,71–0,91), так и беспрогрессивную выживаемость (ОР 0,62, 95% ДИ 0,52–0,74). Количество пациентов, которых необходимо дополнительно пролечить (number needed to treat — NNT) в группе Бев для достижения 1 дополнительного случая ОВ в сравнении с контролем составило 12, в то время как показатель NNH для разных побочных эффектов колебался в пределах 2–124. Полученные результаты демонстрируют, что преимущества терапии Бев перевешивают его возможную токсичность. Данных достаточно для подтверждения целесообразности использования Авастина при метастатическом колоректальном раке.A systematic review and meta-analysis investigating bevacizumab in metastatic colorectal cancer were performed. The primary endpoint was safety and secon dary endpoints were overall survival and progression-free survival. The relative risks for side effects were calcula ted with their 95% confidence interval (CI) using the inverse of variance method. For statistically significant relative risks, number needed to harm were calculated. Authors retrieved 6 out of 17 eligible papers encompassing 3385 patients. Only hypertension (relative risk 2,98 95% CI 2,32-3,84), gastrointestinal perforations (relative risk 5,04 95% CI 1,72–14,79) and bleeding (relative risk 2,07 95% CI 1,19–3.62) were significantly increased. Bevacizumab significantly improved both overall survival (HR 0,80 95% CI 0,71–0,91) and progression-free survival (hazard ratio (HR) 0,62 95% CI 0,52–0,74). Number needed to treat for overall survival is 12, whilst number needed to harms ranges from 2 to 14,286

Monitoring the complex benthic habitat on semi-dark underwater marine caves using photogrammetry-based 3D reconstructions

Marine caves are dark environments considered a priority habitat for conservation included in the EU Habitats Directive (H8330). They harbor fragile benthic communities and represent a major reservoir of marine biodiversity. However, there is a lack of knowledge of these habitats due to the difficulties of creating detailed benthic maps and characterizing the biodiversity, structure, and dynamics of their communities. The uniqueness of marine caves fosters their popularity among recreational divers, who can cause disturbances through abrasion of the biota, resuspension of sediment, and accumulation of exhaled air bubbles in the caves' ceilings. This study aims to build a monitoring framework to characterize the structure and temporal dynamics of this complex habitat using Structurefrom- Motion (SfM) photogrammetry. SfM is a novel, non-invasive technique that allows a major advancement in the monitoring of changes in the cave’s community assemblages. This method relies on images acquired by 4K video footage to build fine-scaled 3D digital models of the substrate using overlapping imagery. For this study, we combined SfM photogrammetry and photo quadrats extracted from the video recordings. We evaluate the effectiveness of this methodology in a marine cave highly frequented by divers, located in Illa de l’Aire (Balearic Islands, Spain), and carried out two surveys before and after the diving season (2019-2021). As a result, we found a loss of 25 colonies of bryozoans with fragile skeletons, like Schizoretepora sp., and 8 individual sponges with globose morphotypes. Our results indicate that this methodology enables accurate and efficient monitoring of benthic communities in underwater caves that allow us to better understand their dynamics and, therefore, to develop the need management measures

Database of spatial distribution of non indigenous species in Spanish marine waters

Research in marine Spanish waters are focused on several actions to achieve an effectively management on protected areas, with the active participation of the stakeholders and research as basic tools for decision-making. Among these actions, there is one about the knowledge and control on NIS. One of its objectives is the creation of NIS factsheets, which are going to be added to the National Marine Biodiversity Geographical System (GIS) providing complementary information about taxonomic classification, common names, taxonomic synonyms, species illustrations, identification morphological characters, habitat in the native and introduced regions, biological and ecological traits, GenBank DNA sequences, world distribution, first record and evolution in the introduced areas, likely pathways of introduction, effects in the habitats and interaction with native species, and potential management measures to apply. The database will also provide data for (1) the European online platforms, (2) the environmental assessment for the Descriptor 2 (D2-NIS) of the EU Marine Strategy Framework Directive (MSFD), as well as (3) supporting decisions made by stakeholders. It is the result of extensive collaboration among scientist, manager’s and citizen science in the Spanish North-Atlantic, South-Atlantic, Gibraltar Strait-Alboran, Levantine-Balearic and Canary Islands marine divisions, providing an updated overview of the spatial distribution of relevant extended and invasive NIS of recent and established NIS introduced by maritime transport and aquaculture pathways, as well as on cryptogenic or native species in expansion due to the climatic water warming trend

The precise alignment of this complex device is a formidable challenge, and only achievable with a significant extension of the technologies routinely used for tracking detectors in the past. This article describes the full-scale alignment procedure as it is used during LHC operations. Among the specific features of the method are the simultaneous determination of up to 200 000 alignment parameters with tracks, the measurement of individual sensor curvature parameters, the control of systematic misalignment effects, and the implementation of the whole procedure in a multi-processor environment for high execution speed. Overall, the achieved statistical accuracy on the module alignment is found to be significantly better than 10μm
