Published: February 2020

AbstractAs a stage of life cycle, larval settlement and metamorphosis are critical processes for persistence of many marine invertebrate populations. Bacterial biofilms (BFs) could induce larval settlement and metamorphosis.Pseudoalteromonas, a widely distributed genus of marine bacteria, showed inductive effects on several invertebrates. However, howPseudoalteromonasBFs induce settlement and metamorphosis ofMytilus coruscusremains unclear.Pseudoalteromonas marinaBFs with the highest inducing activity were further investigated to define inductive cues. Surface-bound products ofP. marinaBFs could induce larval settlement and metamorphosis.P. marinaBFs treated with formalin, antibiotics, ultraviolet irradiation, heat and ethanol significantly reduced inductive effects and cell survival rates. The confocal laser scanning microscopy and the biovolume analysis showed the dominance of α-polysaccharides onP. marinaBFs. Treatment of BFs with amylases, proteases and lipase led to the decrease of inducing activity, suggesting that inductive cues ofP. marinaBFs may comprise of molecular domains of polysaccharides, proteins, and lipids. Finding inductive cues of BFs could put forward further studies about the mechanism of larval settlement and metamorphosis of marine invertebrates.

Published: February 2020

AbstractTo maximize the anodic charge storage capacity of Li-ion and Na-ion batteries (LIBs and SIBs, respectively), the conversion–alloying-type Sb2S3 anode has attracted considerable interest because of its merits of a high theoretical capacity of 946 mAh g−1 and a suitable anodic lithiation/delithiation voltage window of 0.1–2 V vs. Li+/Li. Recent advances in nanostructuring of the Sb2S3 anode provide an effective way of mitigating the challenges of structure conversion and volume expansion upon lithiation/sodiation that severely hinder the Sb2S3 cycling stability. In this context, we report uniformly sized colloidal Sb2S3 nanoparticles (NPs) as a model Sb2S3 anode material for LIBs and SIBs to investigate the effect of the primary particle size on the electrochemical performance of the Sb2S3 anode. We found that compared with microcrystalline Sb2S3, smaller ca. 20–25 nm and ca. 180–200 nm Sb2S3 NPs exhibit enhanced cycling stability as anode materials in both rechargeable LIBs and SIBs. Importantly, for the ca. 20–25 nm Sb2S3 NPs, a high initial Li-ion storage capacity of 742 mAh g−1 was achieved at a current density of 2.4 A g−1. At least 55% of this capacity was retained after 1200 cycles, which is among the most stable performance Sb2S3 anodes for LIBs.

AbstractKnowledge of the effect of soil nutrients, such as K and Na and their interaction with water availability, on the growth and wood properties of the eucalypts, is needed to increase the productivity of commercial plantation forests in Brazil that generate employment and taxes. The present study evaluates the apparent wood density (at 12% wood moisture) of Eucalyptus grandis trees at 12, 24, 36 and 48 months old under ambient and lower than ambient (66%) rainfall conditions and K and Na nutrient enrichment. The treatments were two water availability (100 and 66% of the rainfall) and the three nutrient treatments were: K (4.5 kmol/ha), Na (4.5 kmol/ha) and a control (natural conditions). The apparent wood density of samples at breast height (1.3 m) was determined by X-ray densitometry and digital images. Increased nutrients at all four ages and water availability at 36 and 48 months reduced apparent wood density in E. grandis trees, however, effects of nutrients are lower under water availability reduction. The radial profile of wood density was higher in four-year-old trees, but there was radial variation in apparent wood density at all ages. These findings predict that, under water stress, apparent wood density will not decline in commercial E. grandis plantations fertilized with potassium. The use of sodium, as a substitute of potassium, should consider their negative impacts on wood density of Eucalyptus grandis trees.

Published: February 2020

AbstractThe high prevalence and heavy socio-economic burden for caries of first permanent molars (FPMs) make the prevention of this disease a major public health goal. Current guidelines recommend a preference of fissure sealant (FS) over fluoride varnish (FV) based on two recent systematic reviews. However, evidences of these two studies are weak because of scarce data and some limitations. Besides, an up-to-date large scale randomized controlled trial (RCT) reported commensurate effectiveness of these two techniques. Thus, in order to more accurately compare the clinical efficacy between FS and FV on caries prevention for FPMs, we carried out this systematic review and meta-analysis. A total of 8 RCTs involving 3289 participants and 6878 FPMs fulfilled the inclusion criteria. Our meta-analysis for the first time showed that there was no statistical difference on caries incidence or occlusal DMFS increment between sealant group and fluoride varnish group at 2~3 years’ follow-up. In that sense, biannual applications of FV or FS may be equally effective on caries prevention for FPMs. These results do not support routine recommendation of FS over FV, thus shedding light on current conceptions. Our findings endow clinicians with a window to reconsider the choice between these two techniques.
Functional Adaptations in Isokinetic Performance and Shoulder Mobility in Elite Ultimate Frisbee Players
Authors: Koeble Christoph , Seiberl Wolfgang 
Published: February 2020

AbstractUltimate Frisbee is a team sport where players mainly use their dominant arm for throwing a flying disc. Little is known about possible functional adaptations to this unilateral strain. The purpose of this study was to investigate shoulder rotation strength and range of motion (ROM) in elite Ultimate Frisbee players. We were especially interested in possible sport-specific functional adaptations of peak torque and work ratios as well as the range of motion of agonist and antagonist shoulder rotators regarding laterality between the dominant and non-dominant body sides. For this reason, the concentric external and internal isokinetic (60°/s) shoulder rotation torque and passive glenohumeral rotation ROM were examined in 15 male subjects (27.5 ± 5.5 yrs; all current or former members of the German National Team) and comparisons of dominant to non-dominant body sides were conducted. Maximum strength (work) during external shoulder rotation was higher on the dominant body side compared with the non-dominant body side (8.4 ± 8.4 %; p < 0.01). No side-to-side differences were found in maximum internal rotation strength. Internal rotation ROM and total ROM were smaller on the dominant body side (21 ± 18 %; p < 0.01 and 5 ± 9 %; p < 0.05). Our findings indicate similar adaptation patterns of shoulder rotation mobility compared to other overhead sports, but differing results regarding shoulder rotation strength. Stretching exercises and monitoring programs are recommended for elite Ultimate Frisbee players, starting at the early stages of the career.

AbstractBioassay-guided fractionation of the MeOH extract of Ephedra sinica terrestrial stems, using a PPAR-γ ligand binding assay, resulted in the isolation of 10 compounds, including one new bisabolane-type sesquiterpenoid (10). The structure of the new compound was determined by extensive spectroscopic analysis, including two-dimensional (2D) NMR. Among the isolated compounds, the sitosterol derivatives (1 and 2), flavonoid glucoside (7), and the new sesquiterpenoid (10), showed significant PPAR-γ ligand-binding activity.

Published: February 2020

AbstractPurpose Correct differentiation between malignant and benign incidentally found cystic renal lesions has critical implications for patient management. In several studies contrast-enhanced ultrasound (CEUS) showed higher sensitivity with respect to the accurate characterization of these lesions compared to MRI, but the cost-effectiveness of CEUS has yet to be investigated. The aim of this study was to analyze the cost-effectiveness of CEUS as an alternative imaging method to MRI for the characterization of incidentally found cystic renal lesions.Materials and Methods A decision model including the diagnostic modalities MRI and CEUS was created based on Markov simulations estimating lifetime costs and quality-adjusted life years (QALYs). The recent literature was reviewed to obtain model input parameters. The deterministic sensitivity of diagnostic parameters and costs was determined and probabilistic sensitivity analysis using Monte-Carlo Modelling was applied. Willingness-to-pay (WTP) was assumed to be $ 100 000/QALY.Results In the base-case scenario, the total costs for CEUS were $9654.43, whereas the total costs for MRI were $9675.03. CEUS resulted in an expected effectiveness of 8.06 QALYs versus 8.06 QALYs for MRI. Therefore, from an economic point of view, CEUS was identified as an adequate diagnostic alternative to MRI. Sensitivity analysis showed that results may vary if CEUS costs increase or those of MRI decrease.Conclusion Based on the results of the analysis, the use of CEUS was identified as a cost-effective diagnostic strategy for the characterization of incidentally found cystic renal lesions.

Published: February 2020

AbstractOperating on extended arch aneurysms that contain severe atherosclerotic plaques is difficult. In such cases, the incidence of intraoperative multiple embolization is very high. We applied single-stage hybrid arch repair, which involved ascending aorta replacement and debranching of arch vessels, consecutively with endovascular repair for two patients. This technique was developed to prevent embolization of atherosclerotic plaques during cardiopulmonary bypass, and abrasion of the plaques during thoracic endovascular repair. Both patients recovered without embolic complications.
Acute Stroke Imaging: Current Trends

Published: February 2020

AbstractThe management of acute ischemic stroke has witnessed a paradigm change in the last few years with the advent of mechanical thrombectomy. Imaging plays a key role in evaluation and patient selection. Computed tomography (CT) forms the workhorse in most centers due to its widespread availability and quick performance, though magnetic resonance imaging (MRI) can also be adopted as a reasonable alternative. The key role of imaging is to rule out hemorrhage and other stroke mimics while at the same time establish early signs of ischemia and provide detailed information of cervicocranial vasculature and salvageable brain parenchyma; all in the shortest timeframe. Key imaging predictors of good clinical outcomes are good Alberta stroke protocol early CT score (ASPECTS) (greater than 6) and collateral scores. Selection of patients beyond the standard window period of 6 to 8 hours has become possible by tissue perfusion imaging with some recent trials demonstrating the utility of thrombectomy even up to 24 hours. Quick MRI-based protocols are being devised to achieve similar information as on CT with no adverse effects related to radiation and contrast effects. Research is underway to decipher the intricacies of blood flow in the brain through more sophisticated imaging methods in attempt to increase the base for mechanical thrombectomy, which will benefit more number of patients.
Automated Quantification of Blood Loss versus Visual Estimation in 274 Vaginal Deliveries
Authors: Rubenstein Andrew F. , Zamudio Stacy , Douglas Claudia , Sledge Sharon , Thurer Robert L. 
Published: February 2020

Objective The aim of the study is to compare quantified blood loss measurement (QBL) using an automated system (Triton QBL, Menlo Park, CA) with visual blood loss estimation (EBL) during vaginal delivery.Study Design During 274 vaginal deliveries, both QBL and EBL were determined. The automated system batch weighs blood containing sponges, towels, pads, and other supplies and automatically subtracts their dry weights and also the measured amount of amniotic fluid. Each method was performed independently, and clinicians were blinded to the device's results.Results Median QBL (339 mL [217–515]) was significantly greater than median EBL (300 mL [200–350]; p < 0.0001). The Pearson's correlation between EBL and QBL was poor (r = 0.520) and the Bland–Altman's limits of agreement were wide (>900 mL). QBL measured blood loss >500 mL occurred in 73 (26.6%) patients compared with 14 (5.1%) patients using visual estimation (p < 0.0001). QBL ≥  1,000 mL was recorded in 11 patients (4.0%), whereas only one patient had an EBL blood loss of 1,000 mL and none had EBL >1,000 mL (p = 0.002).Conclusion Automated QBL recognizes more patients with excessive blood loss than visual estimation. To realize the value of QBL, clinicians must accept the inadequacy of visual estimation and implement protocols based on QBL values. Further studies of clinical outcomes related to QBL are needed.Key Points
Role of hydrodynamics in liquid–liquid transition of a single-component substance
Authors: Takae Kyohei , Tanaka Hajime 
Published: February 2020

Significance
Liquid–liquid transition (LLT) in a single-component substance is a counterintuitive phenomenon if we regard a liquid to be isotropic and homogeneous both macroscopically and microscopically. However, we can explain LLT rather naturally once we accept local structural ordering in a liquid. However, there has so far been no study on the role of hydrodynamic interaction, although the fluidity is the most intrinsic feature of liquids. Here we describe a theory of LLT considering the hydrodynamic degree of freedom. Our study not only reveals crucial importance of dynamical coupling between density change upon LLT and hydrodynamic transport but also provides a basis to understand how fluid transport can be coupled to LLT, which may be important for future applications.
Sulfhydration of AKT triggers Tau-phosphorylation by activating glycogen synthase kinase 3β in Alzheimer’s disease
Authors: Sen Tanusree , Saha Pampa , Jiang Tong , Sen Nilkantha 
Published: February 2020

SignificanceIt is well known that AKT inactivates glycogen synthase kinase 3β (GSK3β) by increasing its phosphorylation. The inactivation of GSK3β leads to aberrant phosphorylation of Tau, which is a hallmark of Alzheimer’s disease. However, we found that if phosphorylated AKT is sulfhydrated, it will be unable to inactivate GSK3β and subsequently increases Tau phosphorylation. The influence of sulfhydrated AKT on GSK3β and Tau phosphorylation was reversed in a transgenic AKT-KI+/+mouse, where sulfhydration of AKT residue was mutated to alanine. Thus, AKT-sulfhydration represents a unique posttranslational modification of AKT that can be targeted to suppress phosphorylation of GSK3β and subsequently reduce Tau phosphorylation.
Dimensions of language education policy in Asia
Authors: Liddicoat Anthony J. , Kirkpatrick Andy 
Published: February 2020

Abstract
This paper will identify the major trends that can be determined from an overall study of recent language policies
across Asia. The trends can be seen across three interrelated themes, namely: the promotion and privileging of one language as the
national language as part of an attempt to create a nation state, often in polities that are linguistically extremely diverse; a
decrease in the promotion of indigenous languages other than the national language and the neglect of these in education in many
countries; and the promotion of English as the first foreign language in education systems, often giving other ‘foreign’ languages
a minimal role in education. Possible reasons and motivations for these trends will be discussed and countries where exceptions to
these trends can be identified will be illustrated. The aim of the paper will be to discuss these trends and to critically
evaluate selected language policies. The paper will conclude with predictions for the future linguistic ecology of the region and for the interrelationships of respective national languages, indigenous languages and English
Spoken word processing in bilingual older adults

Published: February 2020

Abstract
We investigated whether bilingual older adults experience within- and cross-language competition during spoken
word recognition similarly to younger adults matched on age of second language (L2) acquisition, objective and subjective L2
proficiency, and current L2 exposure. In a visual world eye-tracking paradigm, older and younger adults, who were French-dominant
or English-dominant English-French bilinguals, listened to English words, and looked at pictures including the target (field), a
within-language competitor (feet) or cross-language (French) competitor (fille, “girl”), and unrelated filler pictures while their
eye movements were monitored. Older adults showed evidence of greater within-language competition as a function of increased
target and competitor phonological overlap. There was some evidence of age-related differences in cross-language competition,
however, it was quite small overall and varied as a function of target language proficiency. These results suggest that greater
within- and possibly cross-language lexical competition during spoken word recognition may underlie some of the communication
difficulties encountered by healthy bilingual older adults.
Update of the BIPM comparison BIPM.RI(II)-K1.Mn-54 of activity measurements of the radionuclide 54Mn to include the 2017 result of the PTB (Germany) and the linked results from the CCRI(II)-K2.Mn-54 comparison

This report concerns an updated submission of a 54Mn standard by the Physikalisch-Technische Bundesanstalt (PTB) to the BIPM.RI(II)-K1.Mn-54 comparison. The result has been added to the previous results and this has produced a revised value for the key comparison reference value (KCRV), calculated using the power-moderated weighted mean. A link has been made to the CCRI(II)-K2.Mn-54 comparison held in 2003 by measurement of the K2 54Mn solution in the International Reference System (SIR). The degrees of equivalence between each equivalent activity measured in the SIR and the KCRV have been calculated for the remaining six NMIs in the BIPM.RI(II)-K1.Mn-54 comparison and the fourteen other participants in the CCRI(II)-K2.Mn-54 comparison. A graphical presentation is included.

On the development of combined tillage working bodies-mechanisms
Authors: Kazakov Yu F , Medvedev V I , Ivanov V M 
Published: February 2020

Abstract
Tillage working bodies of rigid construction, as a rule, have one degree of freedom. A feature of the working bodies-mechanisms, characterized by a high degree of freedom, is the ability to continuously adapt to changing soil conditions. A working body for subsoiling, consisting of a cutting knife with a built-in drier, to which a mole in the form of a spring of a complex shape is attached, is designed. The time-stretched process of entry into operation of adjacent elements of the combined working body, the periodic deviation of the mole from the rectilinear motion, the continuous change in the diameter of the turns and the length of the mole depending on the difference in the longitudinal hardness of the soil helps to reduce the traction resistance.

Abstract
Wax moth is one of the main pests of bee colonies. Bee moth larvae have in their chemical composition many substances that are necessary for the preparation of drugs of the widest range of action. Beekeepers solve the problem of better control of greater wax moths using chemical, biological and other methods. The efficient methods to control Galleria mellonella include physical methods: temperature, radiation, etc. The purpose of this paper is to find the most effective optical radiation for a greater wax moth (Galleria mellonella L.), in which the productivity of bee colonies is maximally preserved, and unscathed G. mellonella larvae can be used to manufacture pharmaceutical preparations and biologically active supplements. The object of research is the Greater wax moth (eggs, larvae, pupae, and imago). We have developed a structure for determining the attractiveness of the optical radiation of different wavelengths for imago of greater wax moths. We found that the optical radiation in the wavelength range of 400…435 nm is the most attractive because it attracted a greater wax moths and therefore the number of eggs laid under the influence of this light was 1.5…2 times higher compared to radiation 491, 546 and 491 nm.
