AbstractBackgroundThis study was to evaluate the prognostic significance of low gradient severe aortic stenosis (LG SAS) and preserved left ventricular ejection fraction (LVEF) with the integration of echocardiographic and clinical data.MethodsThe study included 172 patients with LG SAS (AVAi ≤ 0.6 cm2/m2, mean aortic pressure gradient < 40 mm Hg) and LVEF (≥ 50%). LV outflow tract diameters were measured at both the aortic valve annulus and 5 mm below the annulus for the measurement consistency. Patients were divided into the low flow LG SAS (LF/LG SAS: SVi < 35mL/m2 and AVAi ≤ 0.6 cm2/m2) and normal‐flow LG SAS groups (NF/LG SAS: SVi ≥ 35mL/m2 and AVAi ≤ 0.6 cm2/m2). Echocardiographic findings and clinical data were systematically analyzed with mean follow‐up of 3.0 ± 1.6 years.ResultsLF/LG SAS had significantly smaller AVAi, lower SVi, a higher prevalence of atrial fibrillation (28% vs 12% P = .01) and diabetes (47% vs 27% P = .007) and lower 3‐year cumulative survival than NF/LG SAS. Multivariable analysis showed that dyspnea, renal dysfunction (CI 1.42‐3.99, P < .01), left atrial diameter, and SVi were independently associated with an increased risk for all‐cause mortality. Aortic valve intervention (AVI) improved survival in LF/LG SAS (68% vs 48%, P < .05) in comparison with medical management (HR: 4.20, CI: 1.12‐15.76, P = .03), but only modestly in NF/LG SAS (75% vs 65% P > .05).ConclusionOutcome of LG SAS was independently associated with clinical characteristics. AVI likely improved outcome of LF/LG SAS who had high‐risk clinical characteristics and unfavorable echocardiographic findings.
Warm developmental temperatures induce non‐adaptive plasticity in the intrasexually selected colouration of a dragonfly

1. When the breeding environment fluctuates across generations, reproductive traits may evolve plasticity that optimises the balance between survival and mating success for the prevailing environment.2. For sexually selected colouration, this balance can depend on environmental temperatures. Accordingly, breeding colouration often co‐varies with temperature through space and time. However, whether such traits exhibit plasticity in response to environmental temperatures is poorly understood.3. In the present study, a dragonfly (Pachydiplax longipennis) was reared under ambient or experimentally warmed conditions and tested for plasticity in its intrasexually selected wing colouration. Although wing colouration improves male territorial success, these advantages are smaller under warmer conditions than cooler conditions. It was therefore predicted that males reared under the ambient thermal conditions of the study site (Cleveland, Ohio) would develop more wing colouration than those reared under experimentally warmed conditions.4. Contrary to this prediction, males reared in warm larval temperatures produced more wing colouration. Thus, although the secondary sexual colouration of this species displays some thermal plasticity, it does not appear to be adaptive relative to the known thermal variation of intrasexual selection in this population.5. Given that the environment often determines the strength and direction of sexual selection, future studies should consider the potential for non‐adaptive, and even maladaptive, developmental plasticity in the sexually selected traits of insects.

AbstractDespite evidence for a difference in total brain volume between dyslexic and good readers, no previous neuroimaging study examined differences in allometric scaling (i.e. differences in the relationship between regional and total brain volumes) between dyslexic and good readers. The present study aims to fill this gap by testing differences in allometric scaling and regional brain volume differences in dyslexic and good readers. Object‐based morphometry analysis was used to determine grey and white matter volumes of the four lobes, the cerebellum and limbic structures in 130 dyslexic and 106 good readers aged 8–14 years. Data were collected across three countries (France, Poland and Germany). Three methodological approaches were used as follows: principal component analysis (PCA), linear regression and multiple‐group confirmatory factor analysis (MGCFA). Difference in total brain volume between good and dyslexic readers was Cohen's d = 0.39. We found no difference in allometric scaling, nor in regional brain volume between dyslexic and good readers. Results of our three methodological approaches (PCA, linear regression and MGCFA) were consistent. This study provides evidence for total brain volume differences between dyslexic and control children, but no evidence for differences in the volumes of the four lobes, the cerebellum or limbic structures, once allometry is taken into account. It also finds no evidence for a difference in allometric relationships between the groups. We highlight the methodological interest of the MGCFA approach to investigate such research issues.

Published: January 2020

AbstractOne of the main benefits of unsupervised learning is that there is no need for labelled data. As a method of this category, latent Dirichlet allocation (LDA) estimates the semantic relations between the words of the text effectively and can play an important role in solving various issues, including emotional analysis in combination with other parameters. In this study, three novel topic models called date sentiment LDA (DSLDA), author–date sentiment LDA (ADSLDA), and pack–author–date sentiment LDA (PADSLDA) are proposed. The proposed models extend LDA through some extra parameters such as date, author, helpfulness, sentiment, and subtopic. The proposed models use helpfulness in the Gibbs sampling algorithm. Helpfulness is a part of readers who found the review helpful. The proposed models divide the words into two categories: the words more affected by the distribution of subtopic and the words more affected by the main topic. In this study, a new concept called pack is introduced, and a new model called PADSLDA is proposed for sentiment analysis at pack level. The proposed models outperformed the baseline models because according to evaluations results, the extra parameters can appropriately affect the generating process of words in a review. Sentiment analysis at the document level, perplexity, and topic coherence are the main parameters used in the evaluations.
Southward re‐distribution of tropical tuna fisheries activity can be explained by technological and management change

Published: January 2020

AbstractThere is broad evidence of climate change causing shifts in fish distribution worldwide, but less is known about the response of fisheries to these changes. Responses to climate‐driven shifts in a fishery may be constrained by existing management or institutional arrangements and technological settings. In order to understand how fisheries are responding to ocean warming, we investigate purse seine fleets targeting tropical tunas in the east Atlantic Ocean using effort and sea surface temperature anomaly (SSTA) data from 1991 to 2017. An analysis of the spatial change in effort using a centre of gravity approach and empirical orthogonal functions is used to assess the spatiotemporal changes in effort anomalies and investigate links to SSTA. Both analyses indicate that effort shifts southward from the equator, while no clear pattern is seen northward from the equator. Random forest models show that while technology and institutional settings better explain total effort, SSTA is playing a role when explaining the spatiotemporal changes of effort, together with management and international agreements. These results show the potential of management to minimize the impacts of climate change on fisheries activity. Our results provide guidance for improved understanding about how climate, management and governance interact in tropical tuna fisheries, with methods that are replicable and transferable. Future actions should take into account all these elements in order to plan successful adaptation.
Predictive modelling of illegal fishing in no‐take marine protected areas
Authors: Davis Tom R. , Harasti David 
Published: January 2020

AbstractIllegal fishing is an acknowledged problem within no‐take areas (NTAs), which are frequently used as a marine conservation management tool. While gathering data on illegal fishing is difficult, it is necessary, as these data enable increased efficiency of compliance patrols, where resources are inherently limited. In particular, information about short‐term temporal variations in illegal fishing in NTAs is needed to guide management and compliance efforts. To address this knowledge gap, daily variations in illegal fishing effort were examined using surveillance cameras at two sites in New South Wales, Australia. Generalised linear modelling (GLM) identified that illegal fishing was significantly greater on non‐working days and during periods with no rain, light winds and slight seas. The GLM developed provided useful predictions of illegal activity in both the NTA used to build the model and in a second nearby NTA. The study demonstrated that illegal fishing was principally concentrated on days with good boating conditions and was greater at the study site closer to boat launching facilities. These insights will assist with future targeting of enforcement, community outreach and management efforts, which should focus on days and sites with an increased likelihood of illegal fishing.
Anoxia can increase the rate of decay for cnidarian tissue: UsingActinia equinato understand the early fossil record
Authors: Hancy Anthony D. , Antcliffe Jonathan B. 
Published: January 2020

AbstractAn experimental decay methodology is developed for a cnidarian model organism to serve as a comparison to the many previous such studies on bilaterians. This allows an examination of inherent bias against the fossilisation of cnidarian tissue and their diagnostic characters, under what conditions these occur, and in what way. The decay sequence ofActinia equinawas examined under a series of controlled conditions. These experiments show that cnidarian decay begins with an initial rupturing of the epidermis, followed by rapid loss of recognisable internal morphological characters. This suggests that bacteria work quicker on the epidermis than autolysis does on the internal anatomy. The data also show that diploblastic tissue is not universally decayed more slowly under anoxic or reducing conditions than under oxic conditions. Indeed, some cnidarian characters decay more rapidly under anoxic conditions than they do under oxic conditions. This suggests the decay pathways acting may be different to those affecting soft bilaterian tissue such as soft epidermis and internal organs. What is most important in the decay of soft polyp anatomy is the microbial community, which can be dominated by oxic or anoxic bacteria. Different Lagerstätte, even of the same type, will inevitably have subtle difference in their bacterial communities, which among other factors, could be a control on soft polyp preservation leading to either an absence of compelling soft anthozoans (Burgess Shale) or an astonishing abundance (Qingjiang biota).

AbstractRecently, the demand for flexible or stretchable Internet‐of‐things devices has increased with the rise in popularity of wearables. Also, research is progressing for the development of oxide‐based all‐solid‐state lithium‐ion batteries, which are expected to have improved safety and performance compared with current batteries. Room‐temperature processes for the production of oxide films would facilitate the development of such novel devices. Press forming is a simple room‐temperature process; however, conventional press forming cannot produce highly dense green compacts. Here, we developed a new press forming‐based, room‐temperature process, the mega‐press forming (MF) method, that produces highly dense aggregate oxide films at a pressure below 1 GPa, which is lower than that at which oxide particles fracture, by taking advantage of the differences in cohesive force between microsized and nanosized particles. We used our novel process to produce highly dense lead zirconate titanate aggregate films on aluminum foil at room temperature, and found that when impregnated with silicone oil, these films exhibited low leakage current density and saturated polarization hysteresis properties. Furthermore, we were able to produce films with a porosity of only 6%, which is much lower than that of films produced by conventional press forming (20%). Thus, the MF method will be useful for the development of novel functional composite ceramics that are difficult to fabricate using high‐temperature processes.

AbstractBackgroundConduction disorders requiring permanent pacemaker implantation occur frequently after transcatheter aortic valve replacement (TAVR). This multicenter study explored the feasibility and safety of His bundle pacing (HBP) in TAVR patients with a pacemaker indication to correct a TAVR‐induced left bundle branch block (LBBB).MethodsPatients qualifying for a permanent pacemaker implant after TAVR were planned for HBP implant. HBP was performed using the Select Secure (3830; Medtronic) pacing lead, delivered through a fixed curve or deflectable sheath (C315HIS or C304; Medtronic).Successful HBP was defined as selective or nonselective HBP, irrespective of LBB recruitment. Successful LBBB correction was defined as selective or nonselective HBP resulting in paced QRS morphology similar to pre‐TAVR QRS and paced QRS duration (QRSd) less than 120 milliseconds with thresholds less than 3.0 V at 1.0‐millisecond pulse width.ResultsThe study enrolled 16 patients requiring a permanent pacemaker after TAVR (age 85 ± 4 years, 31% female, all LBBB; QRSd: 161 ± 14 milliseconds). Capture of the His bundle was achieved in 13 of 16 (81%) patients. HBP with LBBB correction was achieved in 11 of 16 (69%) and QRSd narrowed from 162 ± 14 to 99 ± 13 milliseconds and 134 ± 7 milliseconds during S‐HBP and NS‐HBP, respectively (P = .005). At implantation, mean threshold for LBBB correction was 1.9 ± 1.1 V at 1.0 millisecond. Thresholds remained stable at 11 ± 4 months follow‐up (1.8 ± 0.9 V at 1.0 millisecond, P = .231 for comparison with implant thresholds). During HBP implant, one temporary complete atrioventricular block occurred.ConclusionPermanent HBP is feasible in the majority of patients with TAVR requiring a permanent pacemaker with the potential to correct a TAVR‐induced LBBB with acceptable pacing thresholds.

AbstractWe describe a new cell line, Clarias dussumieri fin (ClDuF), from the caudal fin of C. dussumieri using the explant technique followed by cryopreservation. The cryopreserved CiDuF cells were validated for quality and other characteristics. They showed typical epithelial morphology in vitro and epithelial cells outgrew their fibroblast cells after the fifth passage. ClDuF cells had a characteristic sigmoid curve with population doubling in 24 h. Immunotyping of the ClDuF cells against cytokeratin suggested the epithelial lineage. Chromosome analysis showed normal diploid (2n = 50) numbers and the cells did not contain any contamination, including Mycoplasma and other microbes. Partial sequencing of fragments of mitochondrial 16s rRNA and COI genes of ClDuF confirmed that the cell line was initiated from C. dussumieri. Cells at the 10th and 25th passages had more than 80% and 70% viability in the culture, respectively, after 6 months of storage at LN2. These ClDuF cells were morphologically identical to the cells before freezing and the genetic resource of C. dussumieri was preserved. The species‐specific cells can serve as a valuable source for virus isolation, conservation and cloning of somatic cells.

AbstractBackgroundPetrolatum is often used to suppress water evaporation from the skin surface. However, its stickiness, shininess, and other factors make it inconvenient for continuous use.ObjectiveTo compare the effectiveness and usability between a newly developed petrolatum‐based ointment (NOV® II Moisture Balm) and white petrolatum.MethodsTwenty‐nine subjects with atopic dermatitis or xeroderma with symptoms of dry skin applied NOV® II Moisture Balm on the right sides of the face and white petrolatum on the left side, respectively, for 8‐12 weeks. The skin conditions (erythema, exudate/crusting, dryness, and itch) were scored, stratum corneum water content and transepidermal water loss (TEWL) were measured, and the free amino acid and thymic stromal lymphopoietin (TSLP) levels in the stratum corneum were analyzed before and end of the trial.ResultsDryness, exudate/crusting, and TEWL decreased significantly on both the white petrolatum and the NOV® II Moisture Balm sides, while stratum corneum water content and the free amino acid levels in the stratum corneum increased significantly. On the NOV® II Moisture Balm side, erythema and the TSLP levels decreased significantly. In a questionnaire on usability, the subjects felt NOV® II Moisture Balm spread better and were less sticky and shiny than white petrolatum, and more subjects wanted to continue using NOV® II Moisture Balm.ConclusionsNOV® II Moisture Balm was equivalent to white petrolatum in moisturizing and improving the physiologic functions of the skin, but had superior usability.

AbstractThe study assessed the effects of dietary L‐arginine supplementation from days 85 to 115 of gestation on sow performance, litter quality, piglet physiology and survival variables in the first 24 hr of life. Twenty multiparous sows, with a history of hyperprolificacy (more than 14 piglets per litter), were used. A completely randomized experimental design was used, consisting of two treatments: feed supplemented or not with 1% L‐arginine from days 85 to 115 of gestation. The experimental unit consisted of the sow and its respective litter, using 10 replicates per treatment. The sows were distributed into the treatments based on body condition and parity. Supplementation with L‐arginine reduced the within‐litter standard deviation and the within‐litter coefficient of variation of piglet weight at 24 hr by 54 g and 4.14 percentage points respectively (p = .029; p = .035). Supplementation with 1.0% L‐arginine decreased the percentages of piglets weighing less than 800 g by 5.60 and 5.08 points at birth and at 24 hr of life respectively. Piglets from sows supplemented with L‐arginine had higher (p = .088) average rectal temperatures at birth and lower (p = .030) rectal temperature at 24 hr of life in comparison with control piglets. No significant differences in placental weight or estimated colostrum production and intake were observed in the first 24 hr of life. At 24 hr of life, piglets weighing less than 1,000 g and from supplemented sows had lower (p = .048) surface/mass ratios and higher body mass index (p = .070). Piglets from supplemented sows and who weighed 1601 to 1,800 g had lower body mass index and ponderal index (p = .002; p = .003). Supplementation with L‐arginine during the final third of gestation reduces the incidence of unviable piglets (<800 g) and improved litter uniformity and piglets’ body conformation within the first 24 hr of life.
