Influence of Water Aging on Microtensile Bond Strength of a Flowable and a Packable Bulk-fill Resin Composites to Dentin

AIM: Investigation of the aging effect on the microtensile bond strength (μTBS) of bulk-fill resin composite (RC) versus a conventionally incrementally applied one. MATERIALS AND METHODS: A total number of 45 sound human impacted third molars extracted molars have been selected to prepare specimens for the μTBS test. Teeth were randomly divided into three groups (C) according to type of RC material which used for restoring the teeth. Where nanohybrid RC (Grandio®SO) was used as the control Group (C1), packable bulk-fill RC (X-tra fil®) was used for restoring teeth in C2 group and flowable bulk-fill RC (X-tra base®) was used for restoring teeth in C3 group. Each group was further subdivided into 3 subgroups (n = 5) according to the water storage time, where in subgroup 1; teeth were stored for 24 h, subgroup 2; teeth were stored for 3 months while for subgroup 3; and teeth were stored for 6 months. After water storage, teeth were sectioned for preparation of μTBS testing beams. Maximum tensile stresses were recorded in megapascal (MPa). RESULTS: After 24 h of water storage, the X-tra base® showed a higher statistically significant μTBS to dentin (33.82 ± 9.84 MPa) than did the other two types of RCs. After 3 months, the X-tra fil® showed the lowest mean value of μTBS (10.90 ± 5.66 MPa), meanwhile, after 6 months of water storage Grandio®SO showed the highest mean value of μTBS (15.85 ± 6.76 MPa). Regardless of the time the X-tra fil® showed the lowest mean of μTBS (15.07 ± 11.73 MPa), while there is no significant difference between the X-tra base® and Grandio®SO. Furthermore, the water aging adversely affects μTBS values which deceased gradually by time. CONCLUSION: The packable bulk-fill RC characterized by lower μTBS to dentin in comparison to the flowable bulk fill and the incrementally applied nanohybrid RCs. Furthermore, the μTBS of the three tested materials decreased gradually by aging.
Phylogenetic evidence of natural reassortants in the Cucumber mosaic virus population in Poland

Abstract During 2012–2017, new necrotic pathotypes of Cucumber mosaic virus were found in zucchini crops in Poland. The infected plants displayed severe necrosis leading to yield and quality losses. A phylogenetic analysis based on genes encoding the coat and movement proteins had previously revealed that necrotic isolates belonged to IA and II subgroups. In the present work, the complete genome sequences of three necrotic CMV isolates were determined and compared with others described to date. This analysis showed that isolate CMV21 has the haplotype IA-IA-IA, while isolates CMV7 and CMV8 were reassortants between subgroups IA and II with the IA-II-II haplotype (nomenclature according to the subgrouping of the three genomic RNAs). This finding indicates the presence of natural reassortants in the Polish CMV population from zucchini. All three necrotic isolates had a mutation in the 1a protein, E371K, not previously described. These new necrotic isolates might further emerge with potentially enhanced virulence and spread by aphids within the zucchini crop and to other hosts.
Asynchronous mHealth Interventions in Rheumatoid Arthritis: Systematic Scoping Review

Background Mobile devices such as smartphones and tablets have surged in popularity in recent years, generating numerous possibilities for their use in health care as mobile health (mHealth) tools. One advantage of mHealth is that it can be provided asynchronously, signifying that health care providers and patients are not communicating in real time. The integration of asynchronous mHealth into daily clinical practice might therefore help to make health care more efficient for patients with rheumatoid arthritis (RA). The benefits have been reviewed in various medical conditions, such as diabetes and asthma, with promising results. However, to date, it is unclear what evidence exists for the use of asynchronous mHealth in the field of RA. Objective The objective of this study was to map the different asynchronous mHealth interventions tested in clinical trials in patients with RA and to summarize the effects of the interventions. Methods A systematic search of Pubmed, Scopus, Cochrane, and PsycINFO was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Studies were initially screened and later assessed by two independent researchers. Disagreements on inclusion or exclusion of studies were resolved by discussion. Results The literature search yielded 1752 abstracts. After deduplication and screening, 10 controlled intervention studies were included. All studies were assessed to be at risk for bias in at least one domain of the Cochrane risk-of-bias tool. In the 10 selected studies, 4 different types of mHealth interventions were used: SMS reminders (to increase medication adherence or physical activity; n=3), web apps (for disease monitoring and/or to provide medical information; n=5), smartphone apps (for disease monitoring; n=1), and pedometers (to increase and track steps; n=1). Measured outcomes varied widely between studies; improvements were seen in terms of medication compliance (SMS reminders), reaching rapid remission (web app), various domains of physical activity (pedometer, SMS reminders, and web apps), patient-physician interaction (web apps), and self-efficacy (smartphone app). Conclusions SMS reminders, web apps, smartphone apps, and pedometers have been evaluated in intervention studies in patients with RA. These interventions have been used to monitor patients or to support them in their health behavior. The use of asynchronous mHealth led to desirable outcomes in nearly all studies. However, since all studies were at risk of bias and methods used were very heterogeneous, high-quality research is warranted to corroborate these promising results.

Morphological diversity of freshwater fishes differs between realms, but morphologically extreme species are widespread

AIM: The aim was to analyse the morphological diversity of the world freshwater fish fauna. We tested to which extent the distributions of morphological traits are supported by extreme morphologies and how those extreme morphologies are distributed among realms and affect the functional vulnerability. We also analysed the contribution of between‐ and within‐order morphological variability to the morphological differences between realms. MAJOR TAXA STUDIED: Freshwater fish. LOCATION: Global. TIME PERIOD: 1960s–2010s. METHODS: We used a global database of freshwater fishes from the six realms. Ten morphological traits were measured on 9,150 species, that is, 75% of the ca. 13,000 freshwater fish species. A principal components analysis was conducted to combine the 10 traits into a multidimensional space. We used Kolmogorov–Smirnov tests to compare the difference in morphological diversity between the six realms and between and within the major fish orders. We then identified the morphologically extreme species and quantified their contributions to the morphological range to assess the functional vulnerability and redundancy of fish faunas in the six biogeographical realms for freshwater ecosystems. RESULTS: We report a strong morphological variability among freshwater fishes of the world, with significant morphological differences among realm fish faunas, caused by an interplay between taxonomic composition of the realm faunas and morphological differences within orders among the realms. Morphologically extreme species accounted for a large percentage of the filling of the global morphological space and are distributed throughout the world. MAIN CONCLUSIONS: Fish morphological diversity is largely supported by a few species with extreme trait combinations, indicating that functional vulnerability exists throughout the world. Our results suggest that more attention should be paid to these morphologically extreme species and that they should be protected to ensure the sustainability of functions they support.
Improving self-efficacy in the teaching of prospective mathematics teachers by involving them in the online teacher community

Self-efficacy in teaching is very important for prospective teachers. Prospective teachers who have good self-efficacy inteaching can carry out the profession as a teacher well in the future. This study aims to improve the self-efficacy in teaching of prospective mathematics teachers by involving them in the online teacher community. A total of 58 prospective mathematics teachers were included as samples. They were divided into two groups. The experimental group attended micro teaching courses while involved in the online teacher community, on the other hand the control group attended a micro teaching course while assisting the model teacher. Self-efficacy in teaching was measured by a questionnaire at the beginning of the semester as a pre-test and at the end of the semester as a post-test. The results showed that prospective mathematics teacher who took micro teaching courses while involved in the online teacher community experienced a higher increase in self-efficacy compared to those who attended micro teaching courses while assisting the model teacher. These results indicate that the association of prospective mathematics teachers in the online teacher community has a positive effect on increasing their self-efficacy in teaching. In-depth interviews indicate that a combination of synchronous and asynchronous communication plays a role in increasing their self-efficacy. Computer-mediated communication that is context-free and not too bound by social conventions greatly helps increase the self-efficacy of prospective teachers.
A general aerosol-assisted biosynthesis of functional bulk nanocomposites

Abstract Although a variety of nanoparticles with better-than-bulk material performances can be synthesized, it remains a challenge to scale the extraordinary properties of individual nanoscale units to the macroscopic level for bulk nanostructured materials. Here, we report a general and scalable biosynthesis strategy that involves simultaneous growth of cellulose nanofibrils through microbial fermentation and co-deposition of various kinds of nanoscale building blocks (NBBs) through aerosol feeding on solid culture substrates. We employ this biosynthesis strategy to assemble a wide range of NBBs into cellulose nanofibril-based bulk nanocomposites. In particular, the biosynthesized carbon nanotubes/bacterial cellulose nanocomposites that consist of integrated 3D cellulose nanofibril networks simultaneously achieve an extremely high mechanical strength and electrical conductivity, and thus exhibit outstanding performance as high-strength lightweight electromagnetic interference shielding materials. The biosynthesis approach represents a general and efficient strategy for large-scale production of functional bulk nanocomposites with enhanced performances for practical applications. Industrial-scale production of these bulk nanocomposite materials for practical applications can be expected in the near future.
Comparison of the efficacy of half ticagrelor loading doses and clopidogrel in elderly acute coronary syndrome patients in China

Purpose: To evaluate the effects of half-load doses (HLD) of ticagrelor and clopidogrel on elderly acute coronary syndrome patients (ACS) over a period of 90 days. Methods: Seventy-four patients diagnosed as ACS were included in this trial. The patients were randomly distributed into group 1 (treated with HLD ticagrelor, 90 mg LD) and group 2 (treated with clopidogrel, 300 mg LD). The interaction of treatment effect was evaluated using Multivariate Cox proportional hazards regression models. Results: Within three months, a total of 12 patients (16.21 %) died of myocardial infarction or stroke. The endpoint of HLD ticagrelor-treated elderly ACS patients was 20 %, and the incidence of clopidogreltreated endpoints was 14.81 %. Conclusion: In the first 45 patients treated with HLD ticagrelor, their cumulative incidence of cardiac events was relatively high. However, there were no considerable changes in the therapeutic benefits of these two drugs in elderly ACS patients.
Spin Dependent Transport in Novel Magnetic Heterostructures

Magnetic oxides have become of interest source for spin transport devices due to their high spin polarization. But the real applications of these oxides remains unsatisfactory up to date, mostly due to the change of properties as a result of nano structuring. Magnetite (Fe3O4) is one such a material. High Curie temperature and the half metallicity of Fe3O4 make it a good potential candidate for spin transport devices. Studies have shown that the nano structuring Fe3O4 changes most of it’s important properties. This includes high saturation magnetization and drop of conductivity by a few orders of magnitude in Fe3O4 thin films. In this study, we have successfully grown Fe3O4 by reactive sputtering and studied the effect of transition metal buffer layers on structural, transport, and magnetic properties of Fe3O4. It is shown that the lattice strain created by different buffer layers has major impacts on the properties of Fe3O4 thin films. Also for the first time, the magnetic force microscopic measurements were carried out in Fe3O4 thin films through Verway transition. MFM data with the magnetization data have confirmed that the magnetization of Fe3O4 thin films rotate slightly out of the plane below the Verway transition. Fe3O4 thin films were also successfully used in fabricating spin valve structures with Chromium and Permalloy. Here, the Fe3O4 was used to generated the spin polarized electrons through reflection instead of direct spin injection. This is a novel method that can be used to inject spins into materials with different conductivities, where the traditional direct spin injection fails. Also the effect of growth field on Fe3O4 and Fe3O4/Cr/Py spin valves were investigated. In Fe3O4 the growth field xi induced an uni-axial anisotropy while it creates a well define parallel and anti-parallel states in spin valves. Magneto thermal phenomenon including spin dependent Seebeck effect, Planar Nernst effect and Anomalous Nernst effect were measured in ferromagnetic thin films and spin valves. Spin dependent Seebeck effect and planar Nernst effect were directly compared with the charge counterpart anisotropic magneto resistance. All the effects exhibited similar behavior indicating the same origin, namely spin dependent scattering.
Assessment of genetic diversity and population structure of the common littoral shrimp
 
 Palaemon serratus
 
 (Pennant, 1777) by microsatellites: Towards a sustainable management

The common littoral shrimp Palaemon serratus is an ecologically and economically important decapod crustacean. Understanding the spatial structure of its populations is crucial to implement effective management strategies. In this study, 17 polymorphic microsatellite nuclear markers were examined in 252 individuals to explore the genetic diversity and the population structure underlying the geographical distribution of this crustacean in European waters. Basic genetic descriptors, population genetic analyses based on FST, analysis of the molecular variance (AMOVA), Bayesian clustering and the Mantel test were performed. Genetic differentiation was significant among sampling sites. AMOVAs and Bayesian assignment tests showed genetic differentiation among localities from the Atlantic coast and those belonging to the area of the Strait of Gibraltar and the Mediterranean Sea. The Guadalquivir estuary was significantly different from the remaining localities. A biogeographical break was detected to the west of the Strait of Gibraltar, and evidence of isolation by distance was obtained. Localities on both sides of the English Channel showed genetic differentiation with the rest of the Atlantic sampling sites, indicating a biogeographical break in this area. These results will contribute towards the better understanding of the biology and ecology of this shrimp and management of the valuable fishery. Two priority areas were delimited: the Atlantic and the Gibraltar–Mediterranean. The Guadalquivir estuary, Anglesey and Calais should also be considered as different genetic stocks.
Phytochemicals and Nutrient Profiles, Anti-oxidant Activity Study of Three Edible Parts (Flower, Fruit and Stem) of Musa paradisiaca

Musa paradisiaca (Banana plant), which belongs to the family of Musaceae, is a well-known herbaceous flowering edible plant. The flower, fruit, and stem part of the plant have been used for nutrients and health benefits.The aim of this study is to determine the secondary metabolites, proximate composition, minerals, heavy metals, and anti-oxidant activity of three edible parts (flower, unripe fruit, and stem) of Musa paradisiaca.The content of alkaloid and tannin was determined by simple titrimetric method and colorimetric method was used for the determination of the content of phenol and flavonoid. Association of Official Analytical Chemicals (AOAC) method was used for the determination of proximate composition and the content of trace elements was analyzed by using atomic absorption spectrophotometer. The anti-oxidant activity was determined by 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging assay and hydrogen peroxide (H2O2) radical scavenging assay.The results indicated that three edible parts (flower, unripe fruit, and stem) of the banana plant contained a good amount of secondary metabolites (such as alkaloid, phenol, flavonoid, and tannin) and also primary metabolites (such as carbohydrate, protein, and fat). Banana fruit contained a high amount of energy (261.31 kcal/100g) compared to the other two parts (flower, and stem). Iron, potassium, phosphorus, calcium were present in these three edible parts of the banana plant. Lead was found in negligible amount and arsenic was not detected. Fifty percent of ethanolic extract of three edible parts of the banana plant showed significant DPPH free radical scavenging and H202 radical scavenging activity as compared to standard ascorbic acid.Based on these findings, three edible parts of Musa paradisiaca may be recommended as a good source of nutrients.
A continent-scale test of multiple hypotheses on the abundances of Neotropical birds

Explaining variation in the abundance of species remains a challenge in ecology. We sought to explain variation in abundance of Neotropical forest birds using a dataset of population densities of 596 species. We tested a priori hypotheses for the roles of species traits, environmental factors, and species interactions. Specifically, we focused on four factors: 1) body mass (trait), 2) habitat type (environmental factor), 3) net primary productivity (NPP; environmental factor) and 4) species richness of competitors (species interaction). Body size explained much variation in density, although only when analyzed at higher taxonomic levels. Habitat type was a strong predictor of density. The relationship between density and productivity was weak. Densities were related negatively to the species richness of heterospecifics. This trend was particularly strong within closely related groups. Our results show that the influence of energetic factors such as body size and productivity depends on phylogeny, and that they act through indirect relations with other variables; alternative ecological factors such as habitat structure and species interactions play a more direct and stronger role in determining abundance than previously thought.
Pollinator size and its consequences: Predictive allometry for pollinating insects

Body size is an integral functional trait that underlies pollination-related ecological processes, yet it is often impractical to measure directly. Allometric scaling laws have been used to overcome this problem. However, most existing models rely upon small sample sizes, geographically restricted sampling and have limited applicability for non-bee taxa. Predictive allometric models that consider biogeography, phylogenetic relatedness and intraspecific variation are urgently required to ensure greater accuracy. Here, we measured body size, as dry weight, and intertegular distance (ITD) of 391 bee species (4035 specimens) and 103 hoverfly species (399 specimens) across four biogeographic regions: Australia, Europe, North America and South America. We updated existing models within a Bayesian mixed-model framework to test the power of ITD to predict interspecific variation in pollinator dry weight in interaction with different co-variates: phylogeny or taxonomy, sexual dimorphism and biogeographic region. In addition, we used ordinary least squares (OLS) regression to assess intraspecific dry weight – ITD relationships for 10 bee and five hoverfly species. Including co-variates led to more robust interspecific body size predictions for both bees (Bayesian R2: 0.946; ΔR2 0.047) and hoverflies (Bayesian R2: 0.821; ΔR2 0.058) relative to models with ITD alone. In contrast, at the intraspecific level, our results demonstrate that ITD is an inconsistent predictor of body size for bees (R2: 0.02 – 0.66) and hoverflies (R2: −0.11 – 0.44). Therefore, predictive allometry is more suitable for interspecific comparative analyses than assessing intraspecific variation. Collectively, these models form the basis of the dynamic R package, ‘pollimetry’, which provides a comprehensive resource for allometric research concerning insect pollinators worldwide.
Atomic structure of the interface of GaAs on vicinal Si(001)

Abstract The interface structure of GaAs on Si(001) grown by molecular beam epitaxy was examined by high-resolution transmission electron microscopy. The interface was characterized regarding the arrangement of atoms, the chemical abruptness, the structure and density of misfit dislocations, the position of misfit dislocations with respect to the chemical interface and the position and height of substrate steps. An abrupt chemical transition within a bilayer was found between GaAs and Si. The lattice mismatch is relieved by Lomer and 60[ddot] misfit dislocations. 90[ddot] partial and 30[ddot] partial dislocations terminating stacking faults and microtwins also contribute to the mismatch relaxation. Different delocalizations of the Lomer dislocation core along the interface were observed indicating that Lomer dislocations are generated by the agglomeration of two 60[ddot] dislocations that climb along the interface.
