Authors: Kim Kyunghun , Kim Bongjoong , Lee Chi Hwan 
Published: July 2019

AbstractAdvances in printing materials and techniques for flexible and hybrid electronics in the domain of connected healthcare have enabled rapid development of innovative body‐interfaced health monitoring systems at a tremendous pace. Thin, flexible, and stretchable biosensors that are printed on a biocompatible soft substrate provide the ability to noninvasively and unobtrusively integrate with the human body for continuous monitoring and early detection of diseases and other conditions affecting health and well being. Hybrid integration of such biosensors with extremely well‐established silicon‐based microcircuit chips offers a viable route for in‐sensor data processing and wireless transmission in many medical and clinical settings. Here, a set of advanced and hybrid printing techniques is summarized, covering diverse aspects ranging from active electronic materials to process capability, for their use in human skin and eye‐interfaced health monitoring systems with different levels of complexity. Essential components of the devices, including constituent biomaterials, structural layouts, assembly methods, and power and data processing configurations, are outlined and discussed in a categorized manner tailored to specific clinical needs. Perspectives on the benefits and challenges of these systems in basic and applied biomedical research are presented and discussed.

AbstractEarth‐abundant Sn/Cu catalysts are highly selective for the electrocatalytic reduction of CO2 to CO in aqueous electrolytes. However, CO2 mass transport limitations, resulting from the low solubility of CO2 in water, so far limit the CO partial current density for Sn/Cu catalysts to about 10 mA cm−2. Here, a freestanding gas diffusion electrode design based on Sn‐decorated Cu‐coated electrospun polyvinylidene fluoride nanofibers is demonstrated. The use of gaseous CO2 as a feedstock alleviates mass transport limitations, resulting in high CO partial current densities above 100 mA cm−2, while maintaining high CO faradaic efficiencies above 80%. These results represent an important step toward an economically viable pathway to CO2 reduction.

AbstractThis study aims to analyze the factors that influence the preference of producers and processors for paddy production contracts in Benin. Unlike previous research, this study estimates a global model using pooled data of producers and processors. In addition, it compares producers’ willingness to accept contracts’ attributes to processors willingness to pay for the same attributes. Data were collected in Benin from 300 producers and 140 processors of rice selected randomly. An estimation of the conditional logit model indicates that producers prefer contracts specifying cash payment, prefinancing, and quality agreement. Processors, on the other hand, prefer contracts specifying technical assistance for both harvest and all the production activities, and quality agreements. The latent class logit model shows that there is heterogeneity among the preferences of both producers and processors across the classes. However, producers prefer cash payment and processors assistance for harvesting across all the classes. This suggests that cash payment and assistance for harvesting are pivotal for contract selection by producers and processors, respectively. Producers are willing to accept a lower price for their paddy (reduction of 25.86 and 6.64 FCFA/kg) in exchange for specifying a cash payment mechanism and prefinancing in the contract. Processors are willing to pay an additional amount of 5.58 CFA/kg of paddy to secure good quality rice.

AbstractBackgroundDrug overdoses and suicides have been rising since 2000 and are major contributors to a 3‐year decline in US life expectancy. Studies suggest that injured workers have elevated rates of depression and opioid use, but no studies have measured excess mortality related to these risks.Materials and methodsWe linked New Mexico workers' compensation data for 100 806 workers injured in 1994 through 2000 with Social Security Administration earnings and mortality data through 2013 and National Death Index cause of death data. We then estimated the association between receiving lost‐time workers' compensation benefits and mortality hazard ratios (HRs) and 95% confidence intervals (CIs) based on Fine and Gray cause‐specific subdistribution hazards for common causes of death and for drug‐related, suicide, and alcohol‐related mortality.ResultsThere was almost a 3‐fold increase in combined drug‐related and suicide mortality hazard among women (HR = 2.63, 95% CI = 1.91‐3.64) and a substantial increase among men (HR = 1.42, 95% CI = 1.13‐1.79). Circulatory disease mortality hazard was elevated for men (HR = 1.25, 95% CI = 1.05‐1.50).ConclusionWorkplace injuries severe enough to require more than a week off work may impair workers' long‐term health and well‐being. Drug‐related deaths and suicides may be important contributors to the long‐term excess mortality of injured workers. Improved workplace conditions, improved pain treatment, better treatment of substance use disorders, and treatment of postinjury depression may substantially reduce mortality consequent to workplace injuries.
Meat eating in wild hamadryas baboons: Opportunistic trade‐offs between insects and vertebrates
Authors: Schreier Amy L. , Schlaht Renate M. , Swedell Larissa 
Published: July 2019

AbstractThe consumption of meat may provide herbivorous animals with important nutrients that are scarce in their plant‐based diet. Seasonal variation in plant food availability has been suggested to motivate dietary flexibility in a range of species and thus primates may seek more prey when key plant resources are unavailable. Alternatively, prey encounter rate may drive meat eating. Here we investigate patterns of meat eating in hamadryas baboons (Papio hamadryas) at Filoha, Awash National Park, Ethiopia. The Filoha baboons rely largely on doum palm fruit (Hyphaene thebaica), which are available most months of the year, and the young leaves of Acacia senegal, which are more abundant during the wet season. We hypothesized that the baboons would consume more meat when H. thebaica and A. senegal were less available, which we tested by comparing meat eating and consumption of these plant food species from March 2005 through February 2006. Our results reveal a high rate of vertebrate meat eating at Filoha (0.028/hour of observation) compared with other hamadryas sites. We found no relationship, however, between meat eating (either insect or vertebrate) and either rainfall or consumption of H. thebaica or A. senegal, indicating that availability of preferred plant resources does not drive meat consumption. Vertebrate consumption and time spent feeding were significantly negatively associated; there was no relationship, however, between the consumption of animal matter and either home range size or daily path length. Vertebrate and insect consumption alternated throughout the year such that the baboons maintained a small amount of animal matter in their diet year‐round. Our results suggest that the baboons do not often actively seek animal matter, but consume it opportunistically, with the presence of locust and dragonfly swarms driving insect consumption, and both prey availability and the availability of feeding time shaping vertebrate predation.

Abstract2D graphitic carbon nitride (g‐C3N4) nanosheets are a promising negative electrode candidate for sodium‐ion batteries (NIBs) owing to its easy scalability, low cost, chemical stability, and potentially high rate capability. However, intrinsic g‐C3N4 exhibits poor electronic conductivity, low reversible Na‐storage capacity, and insufficient cyclability. DFT calculations suggest that this could be due to a large Na+ ion diffusion barrier in the innate g‐C3N4 nanosheet. A facile one‐pot heating of a mixture of low‐cost urea and asphalt is strategically applied to yield stacked multilayer C/g‐C3N4 composites with improved Na‐storage capacity (about 2 times higher than that of g‐C3N4, up to 254 mAh g−1), rate capability, and cyclability. A C/g‐C3N4 sodium‐ion full cell (in which sodium rhodizonate dibasic is used as the positive electrode) demonstrates high Coulombic efficiency (ca. 99.8 %) and a negligible capacity fading over 14 000 cycles at 1 A g−1.

AbstractAn ultrasound‐assisted direct in situ saponification (U‐DS) process was developed to extract unsaponifiable matter (rich in squalene) from the livers of four fish species, sea bass, skipjack tuna, gray bamboo shark, and spot‐tail shark. The conventional solvent extraction method was used for comparison. Box–Behnken experimental design (BBD) was adopted to optimize the independent variables including the biomass/methanol ratio (1:3 to 1:9 w/v), 50% KOH volume (1–12 mL), and sonication time (0–30 min) over the unsaponifiable yield. With the conventional process, the yield of squalene was 0.10 ± 0.02 to 5.52 ± 0.06 g (100 g)−1, whereas the U‐DS process rendered the yield of 0.13 ± 0.03 to 6.86 ± 0.05 g (100 g)−1, depending on the fish species. After extraction, squalene was further concentrated (purity ≥60%) from all fish species via fractional crystallization (yield of squalene concentrate ranged from 48.35% to 74.49%) and purified using a silica gel column with a maximum recovery up to 98%. For all the fractions, components were examined using thin layer chromatography (TLC). Squalene was qualitatively and quantitatively analyzed using reversed‐phase high‐performance liquid chromatography (RP‐HPLC). Entire extraction processes yielded squalene with a purity of ≥94%. Fourier transform infrared (FTIR) analysis confirmed the native structure of squalene with six nonconjugated bonds, suggesting no degradation of squalene taken place during the U‐DS process. Thus, the U‐DS process along with fractionation and purification could be used for recovering the squalene from fish livers.

Published: July 2019

ABSTRACTA new two‐component modified polyurethane (PU) sealant was designed and synthesized for insulating glass. This sealant was designed based on a crosslinked reaction between a p‐chlorophenol‐blocked PU pre‐polymer (Pre‐polymer 2) in Component A and a poly‐functional hyperbranched polyamine polymer (polyamide resin 300#) in Component B. During the synthesis of Pre‐polymer 2, Fourier transform infrared spectral analysis was used to track the process, and the optimal reaction time and temperature were 1.5 h and 80 °C, in the presence of 4, 4′‐diphenylmethane diisocyanate (MDI). Different curing agents also used as deblocking agents were screened and it was found that polyamide resin 300# was a good candidate for the curing reaction. In addition, the low‐temperature curing rate was also improved by using dibutyltin dilaurate (DBTDL) and organobentonite together as a composite catalyst. Finally, the prepared two‐component modified PU sealant for insulating glass was successfully used in an assembly line with good performance. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.

PremiseThe natural population size of Huperzia serrata (Lycopodiaceae) has dramatically decreased and the species has become endangered due to overexploitation. Here, we developed simple sequence repeat (SSR) markers for H. serrata to survey both its genetic diversity and population structure.Methods and ResultsBased on 177 individuals, 120 SSR primer pairs were developed and optimized from five regions of the H. serrata transcriptomic data. Of these primer pairs, 20 were successfully amplified and 10 showed obvious polymorphism. These polymorphic loci were investigated to study the genetic diversity of H. serrata. Two to 11 alleles per locus were identified, the level of observed heterozygosity ranged from 0.00 to 1.00, and the level of expected heterozygosity ranged from 0.19 to 0.79. All loci were successfully amplified in H. crispata, H. sutchueniana, and H. selago.ConclusionsThe 10 polymorphic primer pairs developed here will be valuable for studies of the endangered H. serrata and other related species.

Published: July 2019

AbstractUnderstanding marine mammal distributions is essential for conservation, as it can help identify critical habitat where management action can be taken. The semi‐enclosed Gulf of Corinth, Greece, has been identified as an Important Marine Mammal Area by the International Union for Conservation of Nature (IUCN) Marine Mammal Protected Areas Task Force, based on the regular occurrence of odontocete populations. A 7‐year (2011–17) dataset of boat‐based surveys was used to model and predict the distribution of striped dolphins,Stenella coeruleoalba, common dolphins,Delphinus delphis, and common bottlenose dolphins,Tursiops truncatus, in the entire Gulf (2400 km2).Multiple geographic, bathymetric, oceanographic, and anthropogenic variables were incorporated in a combined generalized additive model and generalized estimation equation (GAM‐GEE) framework to describe dolphin occurrence and produce distribution maps.Modelling indicated that striped and common dolphins prefer deep waters (>300 m) in the central and southern part of the Gulf, whereas bottlenose dolphins prefer shallow waters (<300 m) and areas close to fish farms along the northern–central shore.Model‐based maps of the predicted distribution identified a preferred habitat encompassing most of the Gulf, also revealing: (i) hot spots of dolphin distribution covering about 40% of the Gulf's surface; (ii) an almost complete overlap of striped and common dolphin distribution, consistent with the hypothesis that common dolphins modified their habitat preferences to live in mixed species groups with striped dolphins; (iii) a clear partitioning of striped/common and bottlenose dolphin habitat; and (iv) the important role played by fish farms for bottlenose dolphins, consistent with studies conducted elsewhere in Greece.Evidence provided by this study calls for area‐specific and species‐specific management measures to mitigate anthropogenic impacts.

Published: July 2019

AbstractSerine hydroxymethyltransferase (SHMT) catalyzes the interconversion of serine and tetrahydrofolate (THF) to glycine and methylenetetrahydrofolate. cDNA encoding Bombyx mori SHMT (bmSHMT) was cloned and sequenced. The deduced amino acid sequence consisted of 465 amino acids and was found to share homology with other SHMTs. Recombinant bmSHMT was overexpressed in Escherichia coli and purified to homogeneity. The enzyme showed optimum activity at pH 3.0 and 30°C and was stable under acidic conditions. The Km and kcat/Km values for THF in the presence of Nicotinamide adenine dinucleotide phosphate (NADP+) were 0.055 mM and 0.081 mM−1 s−1, respectively, whereas those toward NADP+ were 0.16 mM and 0.018 mM−1 s−1 and toward l‐serine were 1.8 mM and 0.0022 mM−1 s−1, respectively. Mutagenesis experiments revealed that His119, His132, and His135 are important for enzymatic activity. Our results provide insight into the roles and regulation mechanism of one‐carbon metabolism in the silkworm B. mori.
Inaction inertia in retirement saving

Published: July 2019

AbstractIn retirement saving, many people miss out on early opportunities to save and subsequently fail to take adequate actions for a long time thereafter. We examined whether these two observations—the initial failure to act and the subsequent inertia—could be related through the phenomenon of inaction inertia. In Experiment 1 (N = 180), participants were less likely to save for retirement when the difference in annual return between the current opportunity and the missed opportunity was large versus small. In Experiment 2 (N = 180), participants were less likely to start saving for retirement when reminded of a missed opportunity 10 years ago versus 1 year ago. These data constitute the first demonstration of inaction inertia in retirement saving: People's reluctance to act on attractive saving opportunities may be induced by their previous inaction. In Experiment 3 (N = 340) and Experiment 4 (N = 628), we find that the observed inertia is the product of a tendency to underestimate exponential growth combined with a focus on past opportunities. Building on this mechanism, Experiment 5 (N = 916) provided evidence for a potential remedy; the inaction inertia effect completely disappeared when focus was shifted from required contributions to future outcomes.

Education policy increasingly promotes action groups as a key strategy for student and/or staff participation in school improvement and whole‐school health promotion. Such groups can coordinate multi‐component interventions, increase participation and engagement, and enable local adaptations, but few process evaluations have assessed this. We evaluated fidelity, feasibility and acceptability of action groups as part of a trial of a whole‐school intervention to reduce bullying and aggression and promote health in English secondary schools, which reported multiple health and educational impacts. Action groups involved students and staff, supported by external facilitators, and drew on data on student needs. They aimed to: coordinate implementation of restorative practices and a social and emotional competencies curriculum; review policies and rules; and enact local decisions to modify school environments. Our process evaluation used interviews, focus groups, observations and questionnaires to assess action groups’ fidelity, role in coordination, role in local adaptation, support from external facilitators and data on student needs, and acceptability in engaging members. Fidelity was high in the first two years but lower in the third year when external facilitators withdrew. Student needs data were perceived as useful, but views on external facilitators were mixed. Groups successfully reviewed policies and rules, planned activities and coordinated restorative practices, but were less successful in implementing the curriculum. Success was facilitated by the involvement of school leaders. Members reported high satisfaction and empowerment. Action groups are a promising strategy for leading whole‐school health promotion. Implementation is supported by external facilitation, local data and involvement of senior managers.

AbstractRare‐earth ions play an important role in eco‐friendly solid‐state lighting for the lighting industry. In the present study we were interested in Eu3+ ion‐doped inorganic phosphors for near ultraviolet (UV) excited light‐emitting diode (LED) applications. Eu3+ ion‐activated SrYAl3O7 phosphors were prepared using a solution combustion route at 550°C. Photoluminescence characterization of SrYAl3O7:Eu3+ phosphors showed a 612 nm emission peak in the red region of the spectrum due to the 5D0→7F2 transition of Eu3+ ions under excitation at 395 nm in the near‐UV region and at the 466 nm blue excitation wavelength. These red and blue emissions are supported for white light generation for LED lighting. Structure, bonding between each element of the sample and morphology of the sample were analysed using X‐ray diffraction (XRD) and scanning electron microscopy (SEM), which showed that the samples were crystallized in a well known structure. The phosphor was irradiated with a 60Co‐γ (gamma) source at a dose rate of 7.2 kGy/h. Thermoluminescence (TL) studies of these Eu3+‐doped SrYAl3O7 phosphors were performed using a Nucleonix TL 1009I TL reader. Trapping parameters of this phosphor such as activation energy (E), order of kinetics (b) and frequency factor (s) were calculated using Chen's peak shape method, the initial rise method and Ilich's method.

AbstractPurposeTo investigate the effect of miR‐107 on the growth and metastasis of gastric cancer (GC) and elucidate the probable mechanisms.MethodsThe expression of miR‐107 and FAT4 in GC tissues and cells were detected using qRT‐PCR. Bioinformatics and dual luciferase reporter gene assays were used to analyze the relationship between miR‐107 and FAT4. miR‐NC, miR‐107 inhibitor, pcDNA3.1‐FAT4 and siRNA‐FAT4 were transfected into AGS and MKN‐45 GC cell lines, respectively. The proliferation and migration abilities of GC cells after transfection were evaluated using the MTT assay, scratch test and transwell assay. The expression of epithelial‐mesenchymal transition (EMT) markers: E‐cadherin, N‐cadherin, vimentin and related proteins of the PI3K/AKT signaling pathway were determined using western blot. The xenograft tumors of nude mice were observed to assess the tumorigenicity of GC cells in vivo.ResultsMiR‐107 was up‐regulated, while FAT4 was down‐regulated in GC tissues and cells (P < 0.05); FAT4 was targeted and negatively regulated by miR‐107. Down‐regulating miR‐107 or up‐regulating FAT4 inhibited the GC cells proliferation, migration, invasion and tumorigenicity, and could also reduce the expression of N‐cadherin, vimentin, p‐PI3K and p‐Akt expression and up‐regulate E‐cadherin.ConclusionsmiR‐107 promotes growth and metastasis in GC via activation of PI3K‐AKT signaling by targeting FAT4, which may be a target for GC treatment.
