Bariatric surgery: a practical pictorial guide for the diagnosis of common and rare complications with upper gastrointestinal imaging series

The aim of this educational poster is to illustrate the role of upper gastrointestinal series (UGS) in detecting the most common and some more rare complications in patients who underwent bariatric surgery procedures as \u2022 laparoscopic adjustable gastric band (LAGB) placement, \u2022 laparoscopic sleeve gastrectomy (LSG), \u2022 Roux-en-Y gastric bypass (RYGB). Our centre (Radiology Unit - Department of Medicine - University Hospital of Padova, Italy) excels in the follow-up of patients who underwent bariatic surgery interventions (in the Week Surgery Unit of the same Hospital). For this reason, our database is rich in images of early and late complications, directly from our clinical practice. In this poster we are going to present, describe and comment the findings to the benefit of all radiologists, not just for those whose field of study is the gastro-intestinal radiology, adding some useful tips for conducting a good examination with high diagnostic relevance

Dynamic semantic ontology generation: a proposal for social robots

[Abstract] During a human-robot interaction by dialogue/voice, the robot cannot extract semantic meaning from the words used, limiting the intervention itself. Semantic knowledge could be a solution by structuring information according to its meaning and its semantic associations. Applied to social robotics, it could lead to a natural and fluid human-robot interaction. Ontologies are useful representations of semantic knowledge, as they capture the relationships between objects and entities. This paper presents new ideas for ontology generation using already generated ontologies as feedback in an iterative way to do it dynamically. This paper also collects and describes the concepts applied in the proposed methodology and discusses the challenges to be overcome.Ministerio de Ciencia, Innovación y Universidades; RTI2018-096338-B-I0

The Large Aperture GRB Observatory

The Large Aperture GRB Observatory (LAGO) is aiming at the detection of the high energy (around 100 GeV) component of Gamma Ray Bursts, using the single particle technique in arrays of Water Cherenkov Detectors (WCD) in high mountain sites (Chacaltaya, Bolivia, 5300 m a.s.l., Pico Espejo, Venezuela, 4750 m a.s.l., Sierra Negra, Mexico, 4650 m a.s.l). WCD at high altitude offer a unique possibility of detecting low gamma fluxes in the 10 GeV - 1 TeV range. The status of the Observatory and data collected from 2007 to date will be presented.Comment: 4 pages, proceeding of 31st ICRC 200

Water Cherenkov Detectors response to a Gamma Ray Burst in the Large Aperture GRB Observatory

In order to characterise the behaviour of Water Cherenkov Detectors (WCD) under a sudden increase of 1 GeV - 1 TeV background photons from a Gamma Ray Burst (GRB), simulations were conducted and compared to data acquired by the WCD of the Large Aperture GRB Observatory (LAGO). The LAGO operates arrays of WCD at high altitude to detect GRBs using the single particle technique. The LAGO sensitivity to GRBs is derived from the reported simulations of the gamma initiated particle showers in the atmosphere and the WCD response to secondaries.Comment: 5 pages, proceeding of the 31st ICRC 200

Propagación in-vitro de cuatro especies de orquídeas nativas de la región Cusco

El cultivo in vitro es una herramienta alternativa para la propagación de especies vegetales en forma masiva. En el presente trabajo se evaluó la germinación asimbiotica de las especies Epidendrum secundum, Rodriguezia longifolia, Bletia catenulata y Epidendrum spilatum en medio de cultivo Murashige y Skoog (M.S.) con tres suplementos orgánicos: agua de coco, pulpa de piña y pulpa de plátano. Las semillas provienen del Distrito de Pillcopata, Provincia de Paucartambo, Región Cusco. Se determinó el tiempo de germinación y su respuesta a tres medios de cultivo con los suplementos orgánicos, comparando con el medio testigo. Se estableció de manera artificial la división de la germinación en cinco etapas diferenciadas: imbibición, cambio de coloración por la transformación de protoplastidios en cloroplastos, inicio de la división celular, formación del protocormo y diferenciación de los órganos vegetativos. Este estudio demostró que el medio M.S suplementado con piña tiene una mejor respuesta a la germinación asimbiótica en las orquídeas Rodriguezia longifolia, Bletia catenulata y Epidendrum spilatum, mientras que para Epidendrum secundum el medio M.S. suplementado con plátano tiene la mejor respuesta a la germinación, de efecto menor es el medio suplementado con coco. El tiempo de germinación para Epidendrum secundum fue de 5 semanas, Bletia catenulata 8 semanas, Epidendrum spilatum 11 semanas y Rodriguezia longifolia 12 semanas. Se obtuvo un efecto positivo sobre la germinación de las semillas en medios con suplementos orgánicos

A sweetpotato gene index established by de novo assembly of pyrosequencing and Sanger sequences and mining for gene-based microsatellite markers

<p>Abstract</p> <p>Background</p> <p>Sweetpotato (<it>Ipomoea batatas </it>(L.) Lam.), a hexaploid outcrossing crop, is an important staple and food security crop in developing countries in Africa and Asia. The availability of genomic resources for sweetpotato is in striking contrast to its importance for human nutrition. Previously existing sequence data were restricted to around 22,000 expressed sequence tag (EST) sequences and ~ 1,500 GenBank sequences. We have used 454 pyrosequencing to augment the available gene sequence information to enhance functional genomics and marker design for this plant species.</p> <p>Results</p> <p>Two quarter 454 pyrosequencing runs used two normalized cDNA collections from stems and leaves from drought-stressed sweetpotato clone <it>Tanzania </it>and yielded 524,209 reads, which were assembled together with 22,094 publically available expressed sequence tags into 31,685 sets of overlapping DNA segments and 34,733 unassembled sequences. Blastx comparisons with the UniRef100 database allowed annotation of 23,957 contigs and 15,342 singletons resulting in 24,657 putatively unique genes. Further, 27,119 sequences had no match to protein sequences of UniRef100database. On the basis of this gene index, we have identified 1,661 gene-based microsatellite sequences, of which 223 were selected for testing and 195 were successfully amplified in a test panel of 6 hexaploid (<it>I. batatas</it>) and 2 diploid (<it>I. trifida</it>) accessions.</p> <p>Conclusions</p> <p>The sweetpotato gene index is a useful source for functionally annotated sweetpotato gene sequences that contains three times more gene sequence information for sweetpotato than previous EST assemblies. A searchable version of the gene index, including a blastn function, is available at <url>http://www.cipotato.org/sweetpotato_gene_index</url>.</p

Multi-messenger observations of a binary neutron star merger

On 2017 August 17 a binary neutron star coalescence candidate (later designated GW170817) with merger time 12:41:04 UTC was observed through gravitational waves by the Advanced LIGO and Advanced Virgo detectors. The Fermi Gamma-ray Burst Monitor independently detected a gamma-ray burst (GRB 170817A) with a time delay of ~1.7 s with respect to the merger time. From the gravitational-wave signal, the source was initially localized to a sky region of 31 deg2 at a luminosity distance of 40+8-8 Mpc and with component masses consistent with neutron stars. The component masses were later measured to be in the range 0.86 to 2.26 Mo. An extensive observing campaign was launched across the electromagnetic spectrum leading to the discovery of a bright optical transient (SSS17a, now with the IAU identification of AT 2017gfo) in NGC 4993 (at ~40 Mpc) less than 11 hours after the merger by the One- Meter, Two Hemisphere (1M2H) team using the 1 m Swope Telescope. The optical transient was independently detected by multiple teams within an hour. Subsequent observations targeted the object and its environment. Early ultraviolet observations revealed a blue transient that faded within 48 hours. Optical and infrared observations showed a redward evolution over ~10 days. Following early non-detections, X-ray and radio emission were discovered at the transient’s position ~9 and ~16 days, respectively, after the merger. Both the X-ray and radio emission likely arise from a physical process that is distinct from the one that generates the UV/optical/near-infrared emission. No ultra-high-energy gamma-rays and no neutrino candidates consistent with the source were found in follow-up searches. These observations support the hypothesis that GW170817 was produced by the merger of two neutron stars in NGC4993 followed by a short gamma-ray burst (GRB 170817A) and a kilonova/macronova powered by the radioactive decay of r-process nuclei synthesized in the ejecta
