Novel surgical technique for complete traumatic rupture of the pancreas: A case report

<p>Abstract</p> <p>Introduction</p> <p>Complete pancreatic rupture is a rare injury. The typical mechanism by which this occurs is overstretching of the pancreas across the vertebral column during blunt abdominal trauma. The management of this injury depends on the location and extent of the injury.</p> <p>Case presentation</p> <p>A 45-year-old Caucasian woman presented with blunt abdominal trauma after she fell onto the end of a handlebar during a bicycle accident. She arrived in the emergency room with stable vital signs and an isolated bruise just above the umbilicus. A computed tomography scan revealed a complete rupture of the pancreas, just ventral to her superior mesenteric vein, and an accompanying hematoma but no additional injuries. An emergency laparotomy was performed; the head of the pancreas was oversewn with interrupted sutures and this was followed by a two-layer pancreaticojejunostomy with the tail of the pancreas. The recovery after surgery was completely uneventful.</p> <p>Conclusions</p> <p>Isolated complete pancreatic rupture is a rare injury that can be managed with complete organ preservation. The combination of suturing the pancreatic head and two-layer pancreaticojejunostomy with the pancreatic tail is a feasible technique to manage this condition.</p

Electrical Transport Properties of Vanadium‐Doped Bi2Te2.4Se0.6

Vanadium‐doped Bi2–xTe2.4Se0.6 single crystals, with x = 0.015 and 0.03, are grown by the Bridgman method. Bandstructure characterization by angle‐resolved photoemission spectroscopy (ARPES) measurements shows gapless topological surface states for both vanadium concentrations. The Van‐der‐Pauw resistivity, the Hall charge carrier density, and the mobility in the temperature range from 0.3 to 300 K are strongly dependent on vanadium concentration, with carrier densities as low as 1.5 × 1016 cm−3 and mobilities as high as 570 cm2 V−1s−1. As expected for transport in gapless topological surface states, the resistivity, carrier density, and mobility are constant below 10 K. The magnetoresistance shows weak antilocalization for both vanadium concentrations in the same temperature range. The weak antilocalization is analyzed with the Hikami–Larkin–Nagaoka model, which yields phase‐coherence lengths of up to 250 nm for x = 0.015.Deutsche Forschungsgemeinschaft http://dx.doi.org/10.13039/501100001659Helmholtz-Gemeinschaft http://dx.doi.org/10.13039/501100001656Peer Reviewe

CEP290 tethers flagellar transition zone microtubules to the membrane and regulates flagellar protein content

Entry and exit of proteins into flagella is gauged by CEP290 in the transition zone

Compositional and textural peculiarities of gold-rich alloys from the Merensky Reef

Gold-rich alloys with variable amounts of Pd from the Merensky Reef, Bushveld Complex, are characterized by a range of finely dispersed inclusions. The small sizes of these inclusions (median of 1,85 µm) make fully quantitative analyses virtually impossible. Tentative interpretation of semi-quantitative microprobe analyses demonstrates the presence of atokite. kotulskite, laurite, moncheite, niggliite, paolovite, rustenburgite, sobolevskite, and sperrylite. Some inclusions appear to represent unnamed minerals. Textures and assemblages imply that these gold grains and their inclusions formed from fluids through occasional remobilisation and co-precipitation

Native osmium from the Guli Massif, Northern Siberia, Russia

Native osmium from two different placer occurrences (i.e., Ingaringda and Burlakovsky) within the Guli Massif, Maimecha-Kotui Province, was evaluated for mineral compositions that show systematic differences between the localities. Grains of native osmium show increases in iridium towards the rim, and nuggets consisting of aggregates define trends of preferential substitution of osmium by iridium. A statistically reliable difference in Os/Ir ratios between the two studied placers can be demonstrated. From textural and compositional characteristics it is concluded that the native osmium of the Burlakovsky placer formed at temperatures higher than can be assumed to be reasonable for crustal conditions. The difference in the Os/Ir ratios between the two placers can be attributed to fractional crystallization of native osmium either in the mantle source, which was tapped in different events to form the Guli Massif, or to decreasing Os/ Ir values during crystallization under crustal conditions after intrusion of the silicate melt(s).This study was partly supported by Russian Foundation for Basic Research (grant 09-05-01242).https://link.springer.com/journal/710am2017Geolog

Reproducible Publications at AGILE Conferences

Reproducible research (RR) is a crucial topic for any research domain using computational processes, including GIScience. Recent research has shown, that AGILE conference (https://agile-online.org/conference) publications leave room for improvement regarding their computational reproducibility. The AGILE council generously supports an initiative for development of new guidelines for AGILE conference submissions to improve reproducibility. The planned duration of the initiative is January 2019 to June 2019. The initiative will prepare new author guidelines and reviewer guidelines suitable for all submission types (full, short, poster). This project captures all material used and created by the initiative. The development versions and base material are collaboratively edited using Google Drive/Docs/Presentations/Spreadsheets. The main outputs are available as PDFs in the "OSF Storage" section of the Files component. https://reproducible-agile.github.io

Exploring the Scope of a Novel Ligand Class: Synthesis and Catalytic Examination of Metal Complexes with ‘Normal’ 1,2,3-Triazolylidene Ligands

Using new ‘normal’-substituted 1,2,3-triazolylidene silver compounds as starting materials allowed for preparation of a series of molybdenum, ruthenium, rhodium, and palladium transition metal complexes bound to the new 1,2,3-triazolylidene ligand system. In this work, the first triazolylidene Mo compound is presented as well as the first structural investigation of a silver complex with a monodentate 1,2,3-triazolylidene. Furthermore, the triazolylidene Pd complex and the Mo complex were tested as precatalysts in Suzuki–Miyaura coupling and epoxidation catalysis, respectively
