Published: July 2019

AbstractLow-accommodation deltaic systems are often challenging to interpret due to their condensed, low-gradient nature, which often results in extensive, sheet-like sandstone bodies. As a result, detailed studies of such systems are scarce, and their internal depositional architecture is still poorly understood. We analyze one such system, the Cenomanian deltaic Mesa Rica Sandstone (Dakota Group), which was deposited in the Western Interior Seaway, in east-central New Mexico, USA. A > 20-km-long escarpment, subparallel to the main delta progradation direction, allows a detailed analysis of facies distribution, depositional architecture, and the spatial extent of stratigraphic surfaces. Results reveal an arrangement of laterally variable shallowing-upward facies successions with three depositional cycles preserved. The first cycle is characterized by deltaic sheet-like sandstone bodies that are consistently overlain by sand-filled amalgamated distributary-channel deposits. The two successive cycles record a progressive reduction of sediment supply into the basin. Vertical and lateral relationships between facies associations and architectural geometries allow the recognition of regional key stratal surfaces, incised-valley fills, and the presence of lagoonal deposits at a sub-regional scale.The Mesa Rica deltaic system represents a river-dominated delta with multiple distributary channels. The sheet-like delta-front sandstone bodies are interpreted as the result of the combined effect of high sandy-sediment supply and low accommodation. The latter acted as an accelerator for autogenic depositional mechanisms such as mouth-bar deposition and abandonment, and for the highly avulsive character of distributary channels. After deposition, minor wave reworking facilitated lateral sand redistribution and favored bioturbation. This study demonstrates that sheet-like delta-front sandstone geometries from low-accommodation systems can be formed without the dominance of wave redistribution processes. This cautions against interpretations of amalgamated shoreline systems based solely on apparent sandstone geometries, without taking into account the preservation potential and postdepositional modification of primary deltaic characteristics.
Reconstruction of Different Wetland Plant Habitats of the Pannonian Basin System (Neogene, Eastern Austria)
Authors: HOFMANN CHRISTA-CHARLOTTE , ZETTER REINHARD 
Published: July 2019

AbstractSedimentary and palynofacies analysis, total organic carbon content (TOC), and palynology from a densely sampled, small, lignite-bearing succession of Late Miocene age at Badersdorf, SE Austria, were compared with modern wetland ecologies. From this, six hydrologically controlled palynofacies types and six associated paleo-plant habitats in an ancient wetland system were differentiated. The associated woody and herbaceous hinterland flora also were distinguished. At least four horizons with relatively high fusinite content have been preserved, indicating occurrence of paleo-wildfires in either the wetland or the hinterland. The palynofacies types were used to determine the taphonomic bias of the associated palynomorph assemblages, which, together with a comparison with modern wetland vegetation, led to differentiation of the paleo-plant habitats. The paleo-wetland was dominated mainly by Glyptostrobus-containing vegetation, and comprised clastic swamp forests with woody angiosperms, natural levee forests, fern- and Glyptostrobus-dominated organic swamps, freshwater marshes, and wet prairies. The occurrence of more than 40 herbaceous taxa at this locality indicates that the lowland vegetation was not composed of only different closed-forest types, but also of areas with herbaceous vegetation. The more zonal vegetation of the adjacent hinterland has been interpreted as a mix of Pinaceae and woody angiosperms with patches of more herbaceous xeric layers.
Plant Taphonomy and Paleoecology of Late Pennsylvanian Intramontane Wetlands in the Graissessac-Lodève Basin (Languedoc, France)
Authors: MARTÍN-CLOSAS CARLES , GALTIER JEAN 
Published: July 2019

Abstract
The Late Pennsylvanian Graissessac-Lodève basin is a small, fluvio-palustrine depocenter located in the southern part of the Massif Central (France). A taphonomic and sedimentologic study carried out in this area allows a reconstruction of Late Carboniferous vegetation in an intramontane context. The paleoecology of such limnic settings is poorly known, and this study permits detailed comparison with paralic basins for the first time. The Graissessac peat mires developed in abandoned fluvial channels, in floodplains, and above distal alluvial fans. The vegetation was dominated by monospecific stands of the arborescent lycopsid Sigillaria brardii, whereas the tree fern Psaronius occurred during the later stages of mire accretion. This is in contrast to coeval North American peat mires, which generally were dominated by tree ferns and pteridosperms throughout the mire profile. Stephanian floodplains and distal alluvial fans of the Graissessac-Lodève Basin were devoid of vegetation, with the exception of isolated thickets of sphenopsids that were composed of Calamites and Sphenophyllum. These plants were found growing in situ in the floodplain mudstones as well as in fine-grained sands of secondary channels. Parautochthonous foliage assemblages of ferns and pteridosperms found in floodplain mudstones represent the most diverse plant community. The plants supplying these remains were growing in exposed areas close to floodplains. Large logs attributed to cordaitaleans and monotypic assemblages of large Cordaites leaves were found in fluvial sediments, and suggest that the plants were riparian elements in the basin.
Relay Strategy and Adaptation to a Muddy Environment in Isselicrinus (Isselicrinidae: Crinoidea)

Published: July 2019

Abstract
Abundant columns of Isselicrinus ariakensis occur in a limited interval of the Upper Eocene Sakasegawa Formation in western Japan. Most of these are several centimeters in length, but curiously they usually stand upright, perpendicular to the bedding plane of the mudstone, and occur as bundles of 2 to 10 columns, with their original distal parts oriented downward. Based on detailed observation of the modes of occurrence as well as on CT scanning of the specimens, a reconstruction of the presumed mode of life is presented. The individuals of Isselicrinus adopted a relay strategy in the muddy substrate, using pre-existing upright columns as anchorage. Similar upright columns of Isselicrinus are also found, or have been reported, from other Eocene and Miocene strata in Japan, Argentina, and Denmark, suggesting that these Isselicrinus adopted this specialized mode of life as an adaptation to muddy bottoms.

Published: July 2019

AbstractThe Permian–Triassic transition was an important time for many marine groups, including echinoderms. However, the fossil record of ophiuroids through this interval is poorly understood. Recent discoveries in Lower Triassic rocks from northern Italy and western US suggest that ophiuroids were more common during this time than previously has been appreciated. Evidence from resting traces (Asteriacites lumbricalis) indicates that Early Triassic ophiuroids lived on fine-grained siliciclastic sediments in oxygenated, shallow-marine environments within storm wave base. No resting traces have been recorded from deeper and/or oxygen-restricted settings. However, following death and decay, ophiuroid skeletal elements sometimes were transported into offshore, low-oxygen environments. All known occurrences of Early Triassic ophiuroids fall within the paleotropics, but this is attributed to sampling bias. Articulated body fossils and their trace fossils are most common in latest Lower Triassic (Olenekian) rocks, but disarticulated ossicles occur throughout the Induan and Olenekian. At times and places, ophiuroids were the dominant marine benthos, carpeting the substrate in prodigious numbers. However, at other times, they also comprised minor components of diverse benthic assemblages, living alongside crinoids (Holocrinus), bryozoans, bivalves, gastropods, and brachiopods. Morphological comparison with extant ophiuroids suggests that all known Early Triassic taxa were small surface-dwellers.
TAPHONOMIC BIAS OF SELECTIVE SILICIFICATION REVEALED BY PAIRED PETROGRAPHIC AND INSOLUBLE RESIDUE ANALYSIS

Published: July 2019

Abstract
Silicification is an important mode of fossil preservation but the extent to which silicified material represents an unbiased sampling of the total fossil assemblage within a given rock sample remains poorly quantified. Here, we use paired analyses of thin sections and acid-extracted silicified specimens from the same samples to examine the biases introduced during silicification of Lower Triassic Virgin Limestone carbonates preserved in the Muddy Mountains of southern Nevada. Bivalves dominate most thin sections in the point count data, but rarely silicify completely enough to be recognized in residue. Echinoderms and gastropods are less abundant in thin section but dominate the residues. The abundances of these groups in thin section and residue are only weakly correlated. These findings suggest that although silicification generally captures relative trends in proportional abundance of higher taxa among samples, the silicification process can be taxonomically biased. Given the biases that can occur during silicification, it should not be assumed that silicified collections present a pristine picture of taxonomic or paleoecologic composition. Petrographic analysis has the potential to illuminate the reliability of paleontological data based on silicified collections.
Off-fault Deformation Associated with Strike-slip Faults
Authors: Johnson Jeffrey A. 
Published: July 2019

AbstractHabitable buildings can be protected from surface fault rupture by establishing structure “setback zones” similar in purpose to legally mandated zones in California and Utah. But post-earthquake surveys of offset and warped linear cultural features, believed to have been straight prior to the event, demonstrate that potentially damaging inelastic strains or off-fault deformation can extend tens of meters beyond the principal slip zone of strike-slip surface fault ruptures. Setback zones designed to also mitigate off-fault deformation are likely to be prohibitively wide, indicating the need for structural and geotechnical engineering solutions to accommodate the potentially damaging strains within adequate design buffers. This study analyzes nine strike-slip surface fault ruptures between 1906 and 2014 and develops a simplified procedure to quantify off-fault deformation based on earthquake magnitude and distance from the principal slip zone of strike-slip faults.
Nanisivik Mine — A Profitability Comparison of Actual Mining to the Expectations of the Feasibility Study
Authors: BURNS NEIL R. , DOGGETT MICHAEL 
Published: July 2019

Abstract
The Nanisivik mine offers a unique opportunity to examine the economics of a mining scenario from its original feasibility study through to closure. In the early 1970s, the Strathcona Sound project (exploration around the Nanisivik mine) had advanced to the point where a significant mineralized body had been defined and a feasibility study was initiated. The study supported development of the Nanisivik mine, with government investment in regional infrastructure, and the mine was constructed and operated for 26 years. Many elements of the feasibility study were difficult to estimate because the project was unique in its high Arctic setting. As a result, many differences were found when comparing the actual mining data to the feasibility study. The majority of these differences were the result of an actual mine life of 26 years instead of the planned 12.5 years. Most of the mining costs were higher than estimated and production occurred at a much higher extraction rate than planned. On a constant dollar basis, the metal prices were, on average, below the feasibility estimates. For the most part, these differences balanced out, with the actual mining being only slightly more profitable than anticipated in the feasibility study.
Geological Setting of the West Meliadine Gold Deposits, Western Churchill Province, Nunavut, Canada
Authors: CARPENTER R.L. , DUKE N.A. 
Published: July 2019

Abstract
The West Meliadine area is underlain by structurally interleaved panels of mafic and minor ultramafic metavolcanic rocks and metasedimentary rocks that occur along the northern margin of the Neoarchean Rankin Inlet greenstone belt. Three structural and metamorphic domains are recognized: (1) the easterly Wesmeg domain; (2) the central Barracuda-Ridge domain; and (3) the westerly Peter Lake domain. The Wesmeg domain is characterized by a series of southeast-trending, north-dipping, foliation-parallel panels of greenschist facies mafic metavolcanic and metasedimentary rocks. The Barracuda-Ridge domain is comprised of greenschist to amphibolite facies mafic metavolcanic rocks that define an east-northeast-trending structural grain. The Peter Lake domain consists of amphibolite facies mafic metavolcanic rocks and minor metasedimentary rocks intruded by a monzonite pluton. West Meliadine hosts the economically significant Wesmeg gold deposits, as well as other important gold showings across the Barracuda-Ridge and Peter Lake domains. The geological setting of the Wesmeg gold deposits resembles that of a break or fault zone. The Pyke Break is a major geophysical discontinuity (>65-km strike length) and is the first-order structural control on gold mineralization at West Meliadine. It is several kilometers wide and characterized by polyphase deformation and shear zone development accompanied by lode-gold mineralization. In general, gold concentration is related to quartz and iron-carbonate veining, iron sulfides (mainly arsenopyrite and pyrrhotite), and accompanying silicate alteration minerals that overprint favorable chemical and structural traps late in the history of deformation.
The ALOHA Trial: (Intra-Articular Local Anaesthetic in Hip Arthroscopy) – A Double-Blinded, 3-Arm Randomised Controlled Clinical Trial Comparing Pre-Emptive, High- and Low-Dose Intra-Articular Local Anaesthetic in Hip Arthroscopy
Authors: Tan Chong Oon , Tran Phong , Chong YewMing , Howard William , Weinberg Laurence 
Published: July 2019

Abstract
Background

Pain after hip arthroscopy is variable but can be severe [11-point Numerical Rating Scale (NRS-11) pain scores of 10] despite multimodal analgesia. Although postoperative rescue regional analgesia is useful in these cases its efficacy may be limited by the maximum safe dose of local anaesthetic (LA) permissible when high-dose intra-articular local anaesthetic (IALA) has already been used. IALA may reduce acute postoperative pain after hip arthroscopy, however neither its optimum dose nor timing of administration have been systematically evaluated.

Methods

In 132 randomly assigned adult patients scheduled for therapeutic hip arthroscopy we compared the effects of two different doses of IALA given at procedure end (Group L [low-dose]: 100mg ropivacaine; Group H [high-dose]: 200mg ropivacaine). We also investigated the effect of an additional pre-emptive dose at the beginning of the procedure (Group P [pre-emptive]: 100mg ropivacaine at procedure start and end).

Results

There were no statistically significant differences between groups for NRS-11 pain scores in recovery (mean[SD]: Group L – 2.2[1.9]; Group H – 2.3[2.1]; Group P – 2.7[2.5]; lowest p = 0.6), or post recovery Visual Analogue Scale (VAS) pain scores [largest mean difference VAS 1.5 hours: 5mm (p = 0.32); VAS 2 hours: 5mm (p = 0.35); VAS 4 hours: 2mm (p = 0.7); VAS 6 hours: 3mm (p = 0.7)]. There were also no significant differences in antiemetic usage and requirement for rescue fascia iliaca block (FIB) between groups.

Conclusions

Compared to a single 100 mg dose of ropivacaine at the end of the procedure, we were unable to demonstrate any advantage of either a higher dose IALA or a pre-emptive dose IALA when multimodal analgesia is used. Lower-dose IALA could reduce total systemic LA absorption if a given rescue regional analgesic LA dose is used postoperatively.
The Use of Data Science to Analyse Physiology of Oxygen Delivery in the Extracorporeal Circulation

Published: July 2019

Abstract
Background
Recent scientific reports brought into light a new concept of goal-directed perfusion (GDP) that aims to recreate physiological conditions in which the risk of end-organ malperfusion is minimalized. The aim of our study was to analyse patient’s interim physiology while on cardiopulmonary bypass based on the haemodynamic and tissue oxygen delivery measurements. We also aimed to create a universal formula that may help in the further implementation of the GDP concept.
Methods
We retrospectively analysed patients operated at Wroclaw University Hospital between June 2017 and December 2018. Since our observations provided a huge amount of data, including the patient's demographics, surgery details, and the perfusion-related data, the Data Science methodology was applied.
Results
A total of 272 (mean age 62.5±12.4, 74% male) cardiac surgery patients were included in the study. To study the relationship between haemodynamic and tissue oxygen parameters, the data for three different values of DO2i (280 ml/min/m2, 330 ml/min/m2 and 380ml/min/m2), were evaluated. Each set of those lines showed a descending function of CI in Hb concentration for the set DO2i.
Conclusions
Modern calculation tools make it possible to create a common data platform from a very large database. Using that methodology, we created models of haemodynamic compounds describing tissue oxygen delivery. The obtained unique patterns may both allow the adaptation of the flow in relation to the patient’s unique morphology that changes in time and contributes to the wider and safer implementation of tailored to individual patient’s needs perfusion strategy.

Published: July 2019

Abstract
Background: Molecularly targeted drugs yielded significant therapeutic advances in oncogene-driven non-small cell lung cancer (NSCLC), but the majority of patients develop acquired resistance. It is important to identify new target sites that mediate lung cancer progression for new targeted drugs development.
Methods: SUSD2 expression and methylation in 25 paired lung cancer and adjacent normal lung samples were investigated. In addition, the association between SUSD2 expression and prognosis was evaluated.
Results: SUSD2 gene expression was down-regulated in 21 of 25 lung cancer samples. Similarly, SUSD2 protein expression was down-regulated in 20 of 25 lung cancer samples. Furthermore, 7 of 25 lung cancer samples showed a higher methylation compared to adjacent normal lung samples, suggesting that SUSD2 methylation was closely associated with silencing of the gene expression. Except for the pathology type and TNM status (P<0.05), no correlation was observed between SUSD2 expression and other clinicopathological characteristics.
Conclusions: Our findings indicated that SUSD2 expression was down-regulated in lung cancer, and SUSD2 methylation might not be involved in SUSD2 gene expression, suggesting that SUSD2 could be a novel candidate gene for future mechanism research of lung cancer.
