Authors: Bai Yingchun , Gao Jiayu , Huang Chengxiang 
Published: October 2022

Abstract
Shell-infill structures consist of exterior solid shell and interior lattice infill, whose closed feature leads to superior comprehensive mechanical performances yet light weight. Additive manufacturing (AM) increases the industrial popularities of shell-infill structures due to its capability to fabricate such complicated integrated structures. However, mechanical performances of integrated manufactured shell structures with lattice infill are still lack of systematic investigation to guide practical application. In this paper, mechanical properties and energy absorption of AlSi10Mg shell structures with BCC (Body Center Cubic) lattice infill by additive manufacturing are investigated. Both quasi-static compressive experiments and corresponding finite element analysis are conducted to investigate the mechanical behaviors. In addition, two different finite element modelling methods are compared to determine the appropriate modelling strategy because combination of shell structures and BCC lattice infill increases the simulations challenges to predict the shell and lattice deformation simultaneously. The results show that the shell-infill structures have a large improvement compared to the lattice structure. The exterior solid shell can enhance the equivalent Young’s modulus by up to 2.3 times. Meanwhile, increasing the infill strut diameter is more conducive to improvement of specific energy absorption by up to 1.6 times.

Abstract
Phytophthora crown rot (PhCR) caused by P. cactorum is one of the most damaging diseases of strawberry worldwide. Mefenoxam is one of the major fungicides currently applied to manage PhCR. However, the emergence and spread of resistant isolates have made controlling the pathogen in the field problematic. In the present study, using whole genome sequencing analysis, mutations associated with mefenoxam-resistant isolates were identified in six different genomic regions of P. cactorum. The 95.54% reads from a sensitive isolate pool and 95.65% from a resistant isolate pool were mapped to the reference genome of P. cactorum P414. Four point mutations were in coding regions while the other two were in noncoding regions. The genes harboring mutations were functionally unknown. All mutations present in resistant isolates were confirmed by sanger sequencing of PCR products. For the rapid diagnostic assay, SNP-based high-resolution melting (HRM) markers were developed to differentiate mefenoxam-resistant P. cactorum from sensitive isolates. The HRM markers R3-1F/R3-1R and R2-1F/R2-1R were suitable to differentiate both sensitive and resistant profiles using clean and crude DNA extraction. Our findings may contribute to a better understanding of the mechanisms of resistance of mefenoxam in oomycetes as well as contribute to the monitoring of P. cactorum populations for the sustainable use of this product.

Abstract
Upstream unrefined petroleum resources and complex operating environments pose a significant threat to the integrity and safety of gathering pipelines. In this work, we proposed a novelty risk assessment method for gathering pipelines. Specifically, the historical failure data were used to develop the fishbone diagram of hazard factors and quantitatively analyze the primary indexes of internal corrosion failure. The risk assessment method was established combined the KENT method and information entropy theory, including models of failure probability and failure consequence coefficient. Subsequently, The welding institute (TWI) risk classification method was adopted to develop the risk classification calculation method for different areas, combined with the area-level safety design coefficient. Finally, the proposed method was applied to 81 gathering pipelines. Research results showed that the risk assessment method proposed in this paper could meet the real safe operation of gathering pipelines, improving upstream energy security.

Published: October 2022

Abstract
Background

The aim of this study was to compare the radiopacity of calcium silicate sealers using a digital imaging method.

Methods

Four calcium silicate-containing sealers, NeoMTA2, BioMTA, ProRoot MTA, and Biodentine, were used in this study. Standard disk-shaped samples were prepared from each root canal filling material and placed on a plexiglass plate. An aluminum penetrometer was placed on a digital radiograph to obtain the irradiation parameters of 70 kVp, 8 mA, and 0.32 seconds. The object-beam distance was adjusted to 30 cm. The grayness values of the tested materials were measured digitally with the system software and compared with a penetrometer to determine the equivalent aluminum thickness.

Results

The radiopacity values of the studied materials in decreasing order, expressed in millimeters of aluminum equivalent, were ProRoot MTA (4.32), Biodentine (2.29), Bio MTA (3.92), and NeoMTA2 (3.83). Statistically significant differences were found between the mean radiographic density values of the tested materials (p < 0.005).

Conclusion

ProRoot MTA was the most radiopaque root canal filling material among the tested materials in this study. All materials, except Biodentine, are compliant with the minimum radiopacity standard recommended by the International Organization for Standardization and the American National Standards Institute/American Dental Association.
Cost-effective climate mitigation via conservation incentives targeting poverty: Bolsa Verde's impact in Brazilian Amazonia settlements
Authors: Costedoat Sebastien , Pfaff Alexander , Coutinho Bruno , Mascia Michael 
Published: October 2022

Abstract
Conservation incentives have been implemented globally to support forests and the ecosystem services they provide (e.g., greenhouse-gas sequestration). Paying forest managers can increase local acceptance of conservation, while also targeting local poverty. Evidence shows that the impacts of incentives vary across contexts and scheme designs, from zero to high. We assess whether deforestation is avoided in sites where households enrolled in Bolsa Verde, a Brazilian governmental conservation program implemented between 2011 and 2018. For enrolled settlements in Amazonia, we estimate that Bolsa Verde reduced deforestation by a total of ~80’000 ha, implying 35 megatons fewer CO2 emissions over the program’s duration and with no evidence of a rebound in forest loss after the program. We find no evidence of avoided deforestation in other program sites – either settlements outside Amazonia or protected areas inside or outside Amazonia. Still, the monetized value of the climate-mitigation benefits for settlements in Amazonia only may well exceed the program’s cost across all its regions.

Abstract
Objective: We aim to investigate the mediating effects of positive coping for the relationship between anxiety, depression and job involvement among medical staff for emergency assistance in Shanghai, China.
Methods: A total of 69 medical staff for emergency assistance were studied in April 2022.We analyzed the data using the multivariate regression model and mediation analysis method.
Results: Anxiety (r=-0.54, p<0.001) and depression (r=-0.63, p<0.001) are negatively correlated with job involvement. It was found that positive coping was significantly correlated with job involvement (r=0.46, p<0.001). The mediation effect of positive coping on the relationship between anxiety and job involvement (=0.87, 95% CI: 0.39~1.34), as well as between depression and job involvement (=0.63, 95% CI: 0.16 ~1.11).
Conclusion: Our results revealed that anxiety/depression could directly affect job involvement. Positive coping played a mediating role between anxiety/depression and job involvement among medical staff. Public health implications: Hospital administrators should provide professional mental health interventions to relieve the anxiety/depression of medical staff , increase their self-confidence and coping ability in handling COVID- 19 practice, enhance positive coping and motivate job involvement.

Abstract
In order to improve Anna apples resistance to hot and dry summer stresses (abiotic stresses) to enhancement the productivity and marketability, Anna apple trees were treated with three growth regulators [naphthalene acetic acid (NAA), 1-methlcyclopropen (1-MCP), and aminoethoxyvinylglycine (AVG)] alone or in combination in two successive seasons. All treatments significantly increased the yield per tree, average fruit volume, fruit diameter and fruit weight compared to control (growing under hot and dry summers which received no treatment). All treatments significantly reduced apple, total soluble solid (TSS) content, fruit softening, anthocyanin content, carotenoid content, total sugar solids, and sugar percentage compared to control. Trees treated with 320-ppm 1-MCP + 250-ppm AVG exhibited maximum yield per tree, fruit firmness, and no-reducing sugars and starch. While 20-ppm NAA produced the maximum TSS content, total sugars, and reducing sugar percentage, carotenoid and anthocyanin fruit content, and (TSS)/acidity ratio. In terms of fruit marketability, the application of all growth regulators remarkably declines the fruit weight loss, fruit firmness loss, and breakdown percentage, as well as decreasing polyphenol oxidase and peroxidase activity at 1-week post-harvest, except for 20-ppm NAA. Additionally, the application of 320-ppm 1-MCP + 250-ppm AVG effectively delayed the harvest for 14 days, whereas the application of NAA effectively moved the harvest date 2 days forward with respect to control. Our results show that specific growth regulator sprays have a significant effect on the productivity and marketability of Anna apples under abiotic stresses

Abstract
Background
Enlarged perivascular spaces (EPVS) of the brain may be involved in dementia, such as Alzheimer’s disease and cerebral small vessel disease (CSVD). Hypertension has been reported to be a risk factor for dementia and CSVD, but the association between blood pressure (BP) and perivascular spaces is still unclear. The aim of this study was to determine the association between BP and EPVS volumes and to examine the interactions of relevant factors.
Methods
A total of 9,296 community-dwelling subjects aged ≥ 65 years participated in a brain magnetic resonance imaging and health status screening examination. Perivascular volume was measured using a software package based on deep learning that was developed in-house. The associations between BP and the EPVS volumes were examined by analysis of covariance and multiple regression analysis.
Results
The mean EPVS volumes increased significantly with rising systolic and diastolic BP levels (p for trend = 0.003, p for trend < 0.001, respectively). In addition, the mean EPVS volumes increased significantly for every 1-mmHg-increment in systolic and diastolic BPs (both p values < 0.001). These significant associations were still observed in the sensitivity analysis after excluding subjects with dementia.
Conclusions
The present data suggest that higher systolic and diastolic BP levels are associated with greater EPVS volumes in cognitively normal older people.

Published: October 2022

Abstract
Extensive evidence supports the claim that serum neurofilament light chain (sNfL) can be used as a biomarker for monitoring disease severity in patients with spinocerebellar ataxia type 3 (SCA3). However, little is known about the associations between sNfL levels and neurochemical alterations in SCA3 patients. Serum samples were collected from ATXN3 mutation carriers (n = 20) and normal controls (n = 14). sNfL levels, measured by a single-molecule array, were compared between SCA3 patients and controls. We explored the relationship between sNfL levels and metabolic changes via magnetic resonance spectroscopy (MRS) scans. sNfL levels in SCA3 patients were higher than those in healthy controls, and these levels were correlated with disease severity. Associations emerged between the elevation of sNfL levels and lower brain metabolite changes, reflected as N-acetyl aspartate/creatine (NAA/Cr). These associations remained significant after multiple comparison corrections. Our results confirmed that serum sNfL levels are increased in SCA3 and are correlated with cerebellar hemisphere metabolic changes. Brain metabolic changes and sNfL levels show promise as potential complementary biomarkers for clinical trials for patients with SCA3.

Published: October 2022

Abstract
Introduction
Abusive head trauma (AHT) is a worldwide leading cause of fatal head injuries in children under 2 years. This study aims to present the development of child protection medical service in Taiwan in the past decade.
Material and methods
This study reviews the evolution of the pediatric protection network and the cross-system professional training in Taiwan from 2013 to 2022. The recommendations of Taiwan Pediatric Association on the prevention and management of AHT and the Medical professionals Manual of Child Abuse and Neglect proposed by the Ministry of Health and Welfare were reviewed.
Results
Considering the impact of the high incidence of severe sequelae and the mortality caused by of AHT, 10 regional centers for child protection medical service were founded in Taiwan to identify, recognize, and properly manage cases of AHT, which is easily overlooked by the healthcare providers. The child protection network across the healthcare, social welfare administration, and judicial systems facilitate the early detection, management, and proper disposition of the children with AHT.
Conclusion
An increasing of the incidence of AHT is expected after the setting up of the child protection network and the continuing cross-system professional trainings. There is more consensus of the diagnosis and management of AHT than before in Taiwan. However, there is no end to protecting children from AHT.

Published: October 2022

Abstract
Carex meyeriana Kunth is a renewable cellulose resource with abundant reserves in nature and has a large research space, but its application is limited and still under development. Hence, Carex meyeriana Kunth is worth developing. Carex meyeriana Kunth's cellulose is abbreviated as CMKC. This study aims to produce cellulose nanofibers (CMKN) from CMKC by electrostatic spinning. The electrostatic spinning solution was prepared by mixing the self-made cellulose solution with 15% polyacrylonitrile, and a CMKN was obtained by electrostatic spinning. The influence of adding cellulose concentration, voltage, the receiving distance, and the pushing speed on the fiber surface morphology was considered. In the tests, the feed rate of the spinning parameters varied in the range of 0.2–1.0 mL/h, the distance from the tip to the acquisition board varied in the range of 10–25 cm, the voltage was 15–25 kV, and the relative humidity was 65%. The fibers were characterized by scanning electron microscopy, X-ray diffraction (XRD), and Fourier transform infrared spectroscopy. The optimal process route was explored. At 21 kV, 20-cm receiving distance, and 0.5 mL/h pushing speed, the spun nanofibers have a smooth surface, a high overall orientation, strong uniformity, and fiber diameter. According to XRD, infrared spectroscopy, and the single-fiber tensile strength test, the crystallinity of cellulose decreases and the tensile strength increases after the transformation from cellulose to nanofiber. Through chemical and mechanical means, we effectively removed the non-cellulose components and increased the cellulose content. The cellulose in the nanofiber is type I. Response surface diagrams help to understand the interaction of these parameters. Langmuir adsorption isotherm is the best fitting model for MB removal by CMKN. The kinetic model is better explained using a pseudo-second-order model. It can be seen from the experiment that the best dye removal conditions are 30℃, MB solution concentration 40mg/L, shock time 90min, 15% cellulose nanofilm removal rate is 63.24%.

AbstractPatterns of the rockcodNotothenia coriicepsinfection with helminths were analysed to understand the dynamics of helminth communities in Antarctic fish and to test their stability over time. The study was performed using helminth samples (30,951 specimens in total) collected from 183N. coriicepsin 2014–2015 and 2020–2021 in the vicinity of the Ukrainian Antarctic station (UAS) "Akademik Vernadsky", Galindez Island, Argentine Islands, West Antarctica. Overall, 25 helminth taxonomical categories (nine trematodes, four cestodes, five nematodes, and seven acanthocephalans) were distinguished and analysed. A direct comparison of the helminth taxonomic categories' prevalences and intensities showed that nine significantly changed their infection parameters during the six years between the samples. Seven of them (Pseudoterranovasp.,Contracaecumsp.,Ascarophis nototheniae, monolocular metacestodes, bilocular metacestodes,Metacanthocephalus rennicki, andDiphyllobothriumsp.) were found to have a significant impact on the differences between helminth infracommunities in 2014–2015 and 2020–2021. The range of changes in meteorological parameters (water and air temperature and water salinity) was not sufficient to significantly impact the helminth community’s patterns; most community patterns showed a stable trend and observed fluctuations were close to the steady trend. Slight but significant changes in the infection patterns observed in this study might have been caused by changes in the populations of intermediate, paratenic, and definitive hosts of helminths (marine invertebrates, mammals, and birds), which participate in helminth transmission in Antarctic ecosystems.
On the Metabolic Conversion of Salicortin-like Chemical Defenses (Salicortinoids) in the Lepidopteran Specialist Herbivore Cerura vinula (Notodontidae)
Authors: Schnurrer Florian , Paetz Christian 
Published: October 2022

Abstract
The lepidopteran specialist herbivore Cerura vinula (Notodontidae) has adapted to thrive on poplar and willow species (Salicaceae). Previous research showed that C. vinula uses a unique mechanism to detoxify the host plant’s defense compounds. After discovering a reductively transformed derivative of tremulacin (6’-O-benzoyl-salicortinol) isolated from the frass of C. vinula, we assessed the chemical stability of salicortin-like defenses (salicortinoids) and analyzed their decomposition products over time and at different pH values. We then incubated uniformly 13C-labeled compounds in vitro with mid-gut homogenates of C. vinula larvae to determine the metabolism of salicortinoids. The key to the metabolic process, we found, is the initial reductive transformation of the salicortinoids; this step reduces the formation of toxic catechol.

Abstract
Spontaneous meningoencephaloceles are often associated with cerebrospinal fluid leak and intracranial hypertension. There is a data scarcity concerning the need for insertion of a cerebrospinal diversion device in these situations. Therefore, we provided an analysis of our patients with spontaneous skull base meningoencephaloceles (MEC) whether their definitive surgical treatment requires management of elevated intracranial pressure (ICP) or not. Retrospective evaluation and data collection of 10 subjects with spontaneous MEC was held. Among others, attention was paid to measuring of ICP, prior interventions, treatment with acetazolamide, characteristics for long term elevated ICP, etc. Our own indications for cerebrospinal fluid (CSF) diversion and use of postoperative external lumbar drain (ELD) underwent analysis as well. The sphenoid region was the most common location of MEC. CSF leak was diagnosed in all subjects. The most common graphical signs of elevated ICP were empty sella and arachnoid pits, both of which were presented in 90% of cases. A lumbar puncture with opening pressure measurement was performed in 7 patients. Ventriculoperitoneal shunt insertion was indicated in 4 cases prior to and in two cases after skull base repair. Two postoperative CSF leaks were managed with ELD and subsequent shunt installation. Spontaneous MECs are often associated with CSF leak. The ICP assessment should be a standard of care to ensure MEC operative repair success. Insertion of a CSF diversion device must be considered where direct or indirect signs of ICH are presented.
