Abstract
The dysregulation of glucose-G6P (glucose-6-phosphate) interconversion is thought to be one of the main reasons for the low glucose disposal of carnivorous fish, but is not yet well understood in largemouth bass Micropterus salmoides (LMB). In this study, the full length cDNA sequences of genes encoding glucokinase (Gck, catalyzing glucose phosphorylation) and glucose-6-phosphatase catalytic subunit (G6pc, catalyzing glucose dephosphorylation) were cloned by the RACE method from the liver of LMB. Subsequently, the distribution of g6pc and gck as well as their transcriptional regulation by dietary starch levels and a glucose load were investigated. Only one gck gene was identified, while the tandem duplication of g6pca.1 gene was named as g6pca.2 in LMB. The full cDNA sequences of g6pca.1, g6pca.2 and gck in LMB were 1585, 1813 and 2115 bp in length, encoding 478, 352 and 359 amino acids, respectively. Gck was predicted to contain two hexokinase domains, an ATP-binding domain and multiple functional sites, while G6pca.1 and G6pca.2 contained nine transmembrane helices, a PAP2 (type-2 phosphatidic acid phosphatase) domain and multiple functional amino acid sites. Both g6pca.1 and g6pca.2 were predominantly distributed in the liver and to some extent in the intraperitoneal fat, intestine and pyloric caeca, while gck was mainly transcribed in the liver and to some extent in the heart, intestine and brain. Both feeding a high starch diet and a glucose load stimulated the mRNA expression of gck in the liver of LMB. An increase of dietary starch from 9% to 14% down-regulated the transcription of g6pca.1 in the liver of LMB. However, both the mRNA levels of hepatic g6pca.1 and g6pca.2 were sharply up-regulated in LMB during 1-3 h after a glucose load. Overall, the results of this study suggested that the functions of G6pc (G6pca.1 and G6pca.2) and Gck in LMB were highly conserved in evolution. Though hepatic glucose-G6P interconversion was well regulated at the transcript level in LMB fed high starch diets, a futile cycle between glucose and G6P was induced in the liver after a glucose load.

Abstract
Solar-driven water evaporation is a promising technology of freshwater production to address the water scarcity. However, the photothermal material and the distilled water would be contaminated in the evaporation of wastewater including organic pollutants. In this work, MOF-derived C/TiO2 composites (carbonized UiO-66-NH2 (Ti)) with simultaneous photothermal and photocatalytic functions are designed for producing freshwater from sewage. With advantageous features of porous structure with large specific area, excellent sunlight absorption and super-hydrophilicity, the carbonized UiO-66-NH2 (Ti) layer exhibits high water evaporation efficiency of 94% under 1.0 sun irradiation. Meanwhile, the layer can simultaneously decompose the organic pollutants with degradation efficiency of 92.7% in the underlying water during solar-driven water evaporation. This bifunctional material will provide a new approach for solar-driven water evaporation and photocatalytic degradation of organic pollutant synergistically.

Abstract
Renewable yet biodegradable natural fiber (e.g., cellulose nanofiber (CNF)) reinforced bio-based polymers (e.g., polylactic acid (PLA)) are being applied for the manufacture of clean packaging products. The interface incompatibility between hydrophilic CNF and hydrophobic PLA still restricts the promotion of high-performance bio-based products. Herein, a polycondensate-coated CNF hybrid, wherein silane, aluminate, and titanate coupling agent monomers were in-situ polymerized onto the CNF surface via dehydration self-condensation, was designed and further employed as strengthening/toughening nanofillers for fabricating the CNF-reinforced PLA composite. Results showed that the polycondensate coatings could efficiently promote the dispersion of CNFs and enhance interfacial compatibility between CNFs and PLA. Attributing to the synergistic effect of polycondensate coatings and CNFs, a considerable improvement in processing, mechanical and thermal properties was obtained in resultant CNF/PLA composites. With adding 2.5 wt% polycondensate-coated CNFs, the tensile strength, Young's modulus, and tensile toughness of CNF-reinforced PLA composites was raised by about 27 %, 51 % and 68 %, respectively; also, such composite possessed greater elasticity and higher melt strength than pure PLA. This study provides a novel interface control strategy to fabricate low-cost yet high-performance PLA-based composites for sustainable packaging application.

Abstract
Interfacial thermal resistance is the main barrier restricting the heat dissipation of thermal management materials in electronic equipment. The interface structure formed by covalent bonding is an effective way to promote interfacial heat transfer. Herein, an integrated composite with multi-aspect covalent bonding beneficial for heat transmission is constructed by polyimide (PI) polymerization with maleimide modified graphene nanosheets (M@GNS). The interfacial structure with low thermal resistance built by covalent bonding and oriented graphene arrangement initiated by the coating process makes the in-plane thermal conductivity of the composite as high as 16.10 W m-1 K-1. Finite element simulation and 1000 bending tests are carried out to further verify the performance advantages of the integrated structure in the internal thermal diffusion and long-term use of the composite. M@GNS/PI with integrated structure provides extra heat transfer channels for heat dissipation, possibly providing an effective way to address the traditional thermal accumulation issue of electronic devices.

Abstract
It is well acknowledged that the microphase-separated morphology of anion exchange membranes (AEMs) is of vital importance for membrane properties utilized in alkaline fuel cells. Herein, a rigid macromolecule poly(methyldiallylamine) (PMDA) is incorporated to regulate the microphase morphology of hyperbranched AEMs. As expected, the hyperbranched poly(vinylbenzyl chloride) (HB-PVBC) is guided to distribute along PMDA chains, and longer PMDA cha leads to a more distinct microphase morphology with interconnected ionic channels. Consequently, high chloride conductivity of 10.49 mS cm-1 at 30 °C and suppressed water swelling ratio lower than 30% at 80 °C are obtained. Furthermore, the β-H of pyrrolidinium cations in the non-antiperiplanar position increases the energy barrier of β-H elimination, leading to conformationally disfavored Hofmann elimination and increased alkaline stability. This strategy is anticipated to provide a feasible way for preparing hyperbranched AEMs with clear microphase morphology and good overall properties for alkaline fuel cells.

Abstract
Evidence-based practice (EBP) requires that clinicians possess skills in appraisal of evidence. Journal club (JC) is demonstrated to increase EBP skills in medicine, nursing, and occupational therapy. Study in physical therapy remains elusive. The objective of this study was to examine the impact of JC on appraisal skills in student physical therapists (SPTs) and explore factors enhancing or hindering the utility of JC. One hundred fifteen SPTs from three cohorts participated in this mixed-methods study. In the first year, participants completed a survey assessing self-reported confidence level on EBP skills before and after attending multiple JCs. Cohorts I and II continued participation in the second year. Additionally, 36 participants attended focus-group interviews after completing 2 years of JC. All cohorts' confidence level increased. Wilcoxon signed-rank test revealed a significant increase (p < 0.001) for cohort III. Remaining cohorts' confidence continuously increased in the subsequent year. Thematic analysis revealed themes on benefits and barriers of JC, strategies for improvements, and connection of JC to clinical practice. The findings indicate that integration of JC promotes SPTs' confidence in EBP skills and connects with practice. Utilizing JC as a pedagogical strategy impacts curricular design and strengthens future health professionals' EBP skills pivotal for delivering quality healthcare.

Abstract
Solar-driven evaporation of water is a sustainable and promising technology for addressing the crisis of clean water. Herein, novel vertically arranged carbon nanotube (V-CNT) aerogels with a tree branch structure is facilely synthesized through an ice templating method. The V-CNT-based photothermal evaporator exhibits efficient broadband light trapping and super-hydrophilicity. Owing to the unique structure and ultrafast water transportation, a high evaporation rate of 3.26 kg m-2 h-1 was achieved by the three-dimensional V-CNT-based evaporator under a solar illumination of 1 kW m-2. More significantly, the V-CNT shows excellent recycling stability and salt-resistant performance in seawater and may provide a novel strategy to the practical sustainable technique of water purification applications.

Abstract
Heat dissipation efficiency and electromagnetic interference (EMI) shielding performance are vital to integration, miniaturization, and application of electronic devices. Flexible and designable polymer-based composites are promising candidates but suffer from unavoidable interfacial thermal resistances, anisotropic thermal conductivity, and low shielding of EMI limiting application. Herein, multifunctional epoxy resin (EP)-based composites with an interconnected carbon fibers (CFs) network structure containing a low thermal resistance interfacial were prepared by high-temperature calcination and infiltration. The coherent heat and electron transfer pathways constructed with self-oriented CFs cloth connected by carbon nanotubes (CNTs) converted from leaf-shaped zeolitic imidazolate frameworks (ZIF-L) and stable magnetic property provided by cobalt nanoparticles contained in the CNTs made composites to an integrated in-plane thermal conductivity of up to 7.50 W m-1 K-1, a through-plane thermal conductivity of 1.96 W m-1 K-1, and an EMI shielding effectiveness of 38.4 dB. Furthermore, the mechanical properties of CFs and the junction effect of CNTs endowed the composites with stability of mechanical property, thermal conductivity, and EMI shielding effectiveness after multiple bendings. The finite element simulation further verified the advantage of CFs network linked by CNTs on heat transfer. This work provides the desired design for the construction of a multifunctional polymer-based composite used in advanced electronic equipment.

Abstract
Every metal and metallurgical industry is associated with the generation of wastewater, influencing the living and non-living environment, which is alarming to environmentalists. The strict regulations about the dismissal of acid and metal into the environment and the increasing emphasis on the recycling/reuse of these effluents after proper remedy have focused the research community's curiosity in developing distinctive approaches for the recovery of acid and metals from industrial wastewaters. This study reports the synthesis of UiO-66-(COOH)2 using dual ligand in water as a green solvent. Then, the prepared MOF nanoparticles were introduced into the DMAM quaternized QPPO matrix through a straightforward blending approach. Four defect-free UiO-66-(COOH)2/QPPO MMMs were prepared with four different MOF structures. The BET characterization of UiO-66-(COOH)2 nanoparticles with a highly crystalline structure and sub-nanometer pore size (~7 Å) was confirmed by XRD. Because of the introduction of MOF nanoparticles with an electrostatic interaction and pore size screening effect, a separation coefficient (SHCl/FeCl2) of 565 and UHCl of 0.0089 m·h-1 for U-C(60)/QPPO were perceived when the loading dosage of the MOF content was 10 wt%. The obtained results showed that the prepared defect-free MOF membrane has broad prospects in acid recovery applications.

Abstract
PURPOSE To explore the underlying risk factors and to prevent misdiagnosis of cervical intraepithelial neoplasia (CIN) coexisted with vaginal intraepithelial neoplasia (VaIN). METHODS Clinical data of patients pathologically diagnosed with CIN were collected from January 2017 to December 2018. A total of 446 cases were analyzed, including 406 cases of single lesions ('CIN single' group) and 40 cases complicated with VAIN ('VAIN concurrent' group). RESULTS The median age of the VAIN concurrent group was 53 years (46.25-59 years), and the median age of the CIN single group was 44 years (36-50 years). Regarding menopausal status, there were 28 cases (70.0%) in the VAIN concurrent group and 89 cases (21.9%) in the CIN single group (P < 0.005). The median load of high-risk human papillomavirus (Hr-HPV) in the VAIN concurrent and CIN single group was 923.4 relative light units/cutoff (RLU/CO) (145-2172.2 RLU/CO) and 229.155 RLU/CO (18.615-638.1275 RLU/CO), respectively (P = 0.037). The results revealed that the menopausal status was an independent risk factor for VAIN occurrence in CIN patients. The risk of VAIN in menopausal patients was higher than that in non-menopausal CIN patients (OR = 8.311, 95% CI 4.062-17.005). Age and HPV load were also related to the concurrence of VAIN and CIN. CONCLUSION Examinations regarding vaginal screening are of great importance in the diagnosis of perimenopausal and postmenopausal CIN patients, especially patients with Hr-HPV load. Colposcopy and tissue biopsy should also be performed, when necessary, to avoid misdiagnosis and the appearance of vaginal lesions.

Abstract
OBJECTIVES To investigate the prevalence of sarcopenia and dysphagia in nursing homes and to analyze the associations between sarcopenic parameters and dysphagia. DESIGN A cross-sectional study. SETTING Nursing homes in Chengdu, Sichuan, China. PARTICIPANTS The study included 365 participants (122 men and 243 women) aged 60 years or older who could walk independently or with walking aids for at least 50 meters. MEASUREMENTS Dysphagia was defined by the water swallow test and sarcopenia and its components were evaluated by the criteria of the Asian Working Group for Sarcopenia, 2019. The values and percentages of sarcopenia associated parameters in relation to dysphagia were analyzed in both male and female residents. The Benjamini-Hochberg method was used to adjust for multiple comparisons. The relationship between sarcopenic components and dysphagia was analyzed using multivariate logistic regression analysis by sex. RESULTS A total of 365 residents (mean age: 84.28 years; 122 men and 243 women) were included in the study. Sarcopenia was diagnosed in 63.0% (n=230) and dysphagia in 75.3% (n = 275) of residents. For men, the percentage of sarcopenia was higher in residents with dysphagia. However, the sarcopenia percentage did not differ significantly between women with and without dysphagia. In both men and women, the handgrip strength (HGS) values were significantly lower in the dysphagic residents. The calf circumference (CC) value and appendicular skeletal muscle index (ASMI) were significantly lower in dysphagic men, while the SARC-CalF scores were higher. In women, the SPPB score was lower in residents with dysphagia. Furthermore, multivariate logistic regression analysis showed that low calf circumference (OR 4.415, 95% CI 1.561-12.490) and sarcopenia (OR 2.968, 95% CI 1.121-7.858) were significantly associated with dysphagia in men after adjusting for co-factors. CONCLUSION There is a high percentage of both dysphagia and sarcopenia in nursing home residents in West China. Low calf circumference and sarcopenia had strong associations with dysphagia among male nursing home residents.

Abstract
Mitochondrial DNA copy number (mtDNA-CN) measured from blood specimens is a minimally invasive marker of mitochondrial function that exhibits both inter-individual and intercellular variation. To identify genes involved in regulating mitochondrial function, we performed a genome-wide association study (GWAS) in 465,809 White individuals from the Cohorts for Heart and Aging Research in Genomic Epidemiology (CHARGE) consortium and the UK Biobank (UKB). We identified 133 SNPs with statistically significant, independent effects associated with mtDNA-CN across 100 loci. A combination of fine-mapping, variant annotation, and co-localization analyses was used to prioritize genes within each of the 133 independent sites. Putative causal genes were enriched for known mitochondrial DNA depletion syndromes (p = 3.09 × 10-15) and the gene ontology (GO) terms for mtDNA metabolism (p = 1.43 × 10-8) and mtDNA replication (p = 1.2 × 10-7). A clustering approach leveraged pleiotropy between mtDNA-CN associated SNPs and 41 mtDNA-CN associated phenotypes to identify functional domains, revealing three distinct groups, including platelet activation, megakaryocyte proliferation, and mtDNA metabolism. Finally, using mitochondrial SNPs, we establish causal relationships between mitochondrial function and a variety of blood cell-related traits, kidney function, liver function and overall (p = 0.044) and non-cancer mortality (p = 6.56 × 10-4).

Abstract
With a trend of continuing improvement in the development of electronic devices, a problem of serious heat accumulation has emerged which has created the need for more efficient thermal management. Graphene sheets (GNS) have drawn much attention with regard to heat transfer because of their excellent in-plane thermal conductivity; however, the ultrahigh interfacial thermal resistance between graphene lamellae has seriously restricted its practical applications. Herein, we describe heat transfer membranes composed of graphene which have been modified by intrinsic thermally conductive polymers with different molecular weights. The presence of macromolecular surface modifiers not only constructed the graphene heat transfer interface by π-π interactions, but also significantly enhanced the membranes' in-plane thermal conductivity by utilizing their intrinsic heat transfer properties. Such results indicated that the in-plane thermal conductivity of the fabricated membrane exhibits a high in-plane thermal conductivity of 4.17 W m-1 K-1, which, containing the GNS modified with 6000 g/mol (Mn) of poly(3-hexylthiophene) (P3HT), was 26 times higher that of poly (vinylidene fluoride) (PVDF). The P3HT molecular chain with specific molecular weight can form more matching structure π-π interactions, which promotes thermal conductivity. The investigation of different molecular weights has provided a new pathway for designing effective interfacial structures to relieve interface thermal resistance in thermally conductive membranes.

Abstract
Fusarium head blight (FHB) causes yield loss, quality reduction, and grain mycotoxin accumulations. A novel pydiflumetofen-containing fungicide, Miravis Ace, was recently registered in North America. The main objective of this study was to assess the efficacies of Miravis Ace and the timing of application alongside industry standard triazole fungicides (Prosaro, Caramba, Proline and Folicur) on suppressing FHB, reducing mycotoxins and improving wheat agronomic performance. The assessment was conducted across six natural environments on commercial farm fields and in two artificially inoculated-misted environments. All environments included 5 fungicides (Miravis Ace and the four triazole fungicides) and 3 application timings (Zadoks GS 59, 65, 69-71). Additionally, for the ZGS 65 timing, the experiment in the natural environment included a quinone outside inhibitor (QoI) fungicide pyraclostrobin (Headline). In general, Miravis Ace tended to be more effective on FHB suppression than the triazole fungicides across all environments. However, any biological differences tended to be statistically non-significant, likely because of a lack of statistical power. Miravis Ace reduced total deoxynivalenol (DON) concentration by 52-73% compared to the non-treated control. If applied at ZGS 59-65, Miravis Ace was more effective in increasing yield and test weight than the triazoles tested. Across fungicides, applications made at ZGS 65 were most effective in FHB suppression compared to earlier or later application timings. There was no evidence that pyraclostrobin increased mycotoxin concentrations. Overall, compared to the triazole fungicides, the novel pydiflumetofen-containing fungicide tended to have lower FHB suppression and mycotoxins, higher grain yield and test weight, and higher harvest moisture, but differences were not always statistically significant. Because the main active ingredient in Miravis Ace has a different mode of action than the triazoles, we speculate that this fungicide will be competitive with industry standards, and benefit strategies for fungicide resistance management.

Abstract
Abstract
In this work, a series of bimodal polymethyl methacrylate (BPMMA) was fabricated via solution-blending two neat PMMA resins. Rheology, DMTA, thermal infrared imager measurements were used in an attempt to probe the internal structure of the as-prepared BPMMA. It was demonstrated that the thermorheological behavior of the BPMMA was heavily dependent on shear rate, temperature as well as blending ratio. In addition, a typical “V-shaped” response, namely, a dip in storage modulus (G′) followed by an upturn in the plot of G′ versus measuring temperature for D4 (with lower weight-average molecular weight) was observed, characteristic of occurrence of thermorheological complexity. Our experimental results of physical–mechanical testings suggested that the BPMMA had better comprehensive properties than those of their neat PMMA counterparts.

Abstract
Vascular dementia is the second-most cause of dementia, characterized by cerebral infarcts, white matter lesions, myelin loss and often amyloid angiopathy. Hence, vascular damage is a critical cause of neuronal loss and synaptic disintegration. Abnormal neuroinflammation, autophagy and apoptosis are the prerequisite factors for endothelial and neuronal cell damage. This leads to the onset and progression of cerebrovascular disorders and cognitive dysfunction. The innate immune cells, pattern recognition receptors, Toll-like receptor-4 and related inflammatory mechanisms disrupt cerebrovascular integrity via glial activation and increased pro-inflammatory interleukins and TNFα. Inflammasome polymorphisms and multi-faceted neuro-immune interactions further integrate systemic and central inflammatory pathways, which induce vascular tissue injury and neurodegeneration. Specifically, chronic cerebral hypoperfusion disrupts the self-cannibalization mechanism of autophagy via altered expression of autophagy-specific proteins, Beclin-1, LC3 and P62. The deregulated autophagy pathway causes neuronal loss, hippocampal shrinkage, and ultimate loss in synaptic plasticity. The vascular dementia models typically exhibit downregulated anti-apoptotic Bcl-2 and upregulated pro-apoptotic Bax, cleaved caspase-3, and cleaved-PARP levels in the brain, for which modulated p38 MAPK and JNK phosphorylation pathways play a vital role. Endoplasmic stress-induced apoptosis, calcium overload and glutamate excitotoxicity in combination with ASK1-MAPK signaling mechanism also contribute to the cerebrovascular pathology. Vascular injury reduces neurological scores and increases the infarct volume, DNA damage and neuronal apoptosis in ischemia/reperfusion injury. Additionally, synergistic and additive interactions between inflammasome, autophagy and apoptotic signaling pathways augment symptoms of vascular neurodegeneration. Overall, the current review enlightens the key risk factors and underlying mechanism triggering vascular dementia. The review additionally informs the challenges associated while treating vascular dysfunction, and highlights the need for targeted drugs for reducing cerebrovascular damage.

Abstract
OBJECTIVE Glioma is a highly aggressive and lethal brain tumor. Anesthetics have been shown to have important effects on the biological characteristics of cancer cells. Nevertheless, the molecular mechanism of anesthetic-mediated glioma cells progression remains unclear. MATERIALS AND METHODS Sevoflurane (sev) was employed to treat glioma cells. The biological characteristics (viability, colony formation, apoptosis, cell cycle, migration, and invasion) of glioma cells were determined via Cell Counting Kit-8 (CCK-8), cell colony formation, flow cytometry, PI cytometry, or transwell assays. The protein levels of Cell Cycle Dependent Kinase (CDK) 2, CDK4, E-cadherin, N-cadherin, Vimentin, and Transforming Growth Factor Beta (TGFB) induced factor homeobox 2 (TGIF2) were assessed through Western blot analysis. Glucose consumption and lactate production were measured using special commercial kits. The expression of circular RNA has_circ_0012129 (circ_0012129) and miR-761 was detected via quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The relationship between circ_0012129 or TGIF2 and miR-761 was verified with Dual-Luciferase reporter assay. Sevoflurane-mediated molecular mechanisms have been confirmed via xenograft assay. RESULTS Sevoflurane suppressed viability, colony formation, cell cycle, migration, and invasion and promoted apoptosis of glioma cells in vitro, and impeded tumor growth in vivo. Circ_0012129 and TGIF2 were downregulated and miR-761 was upregulated in sevoflurane-treated glioma cells. Circ_0012129 elevation abolished sevoflurane-mediated biological characteristics of glioma cells. MiR-761 served as target for circ_0012129 and miR-761 targeted TGIF2. Moreover, both miR-761 overexpression and TGIF2 suppression restored circ_0012129 enhancement-mediated biological characteristics of sevoflurane-treated glioma cells. CONCLUSIONS Sevoflurane mediated the progression of glioma via regulating the circ_0012129/miR-761/TGIF2 axis.

Abstract
Background To explore the prevalence of dental anxiety (DA) in patients with third molar extractions and its influence factors and the correlation between DA levels and postoperative pain.
Material and Methods A prospective and descriptive clinical study was performed. All patients who underwent the impacted third molar extraction from October 2017 to February 2019 were enrolled. DA levels were assessed by virtue of the modified dental anxiety scale (MDAS) and pain was assessed with a visual analog scale (VAS).
Results A total of 150 patients were investigated and 136 valid questionnaires were retrieved, with an effective rate of 90.7%. The independent sample t-test and ANOVA results showed that the anxiety level of patients with the third molar extractions was statistically different in gender, teeth extraction experience and self-assessment oral health status. Multiple linear regression analysis with DA as a dependent variable showed that gender and teeth extraction experience were independent factors influencing DA in patients with third molar extractions. Pearson's test showed that there was a significant correlation between DA level in patients and the postoperative pain on the first day (r=0.542, p=0.000).
Conclusions For patients (females, poor oral hygiene and no teeth extraction experience), surgeon should pay more attention to DA of such patients and take measures to reduce the anxiety when removing the third molars. Furthermore, surgeon can recommend oral administration ibuprofen sustained release capsules after surgery. Key words:Dental anxiety, modified dental anxiety scale, visual analogue scale, postoperative pain.

Abstract
Abstract
Introduction/Objective
Duodenal epithelial polyps are reported in up to 3% of patients referred for upper endoscopy. Most include non-neoplastic lesions such as Brunner gland nodule/polyp and pancreatic or gastric heterotopia.
Neoplastic lesions such as pyloric gland adenomas (PGA) are less frequently encountered and have the propensity to progress to adenocarcinoma. Herein we report a duodenal submucosal glandular lesion that has a morphologic resemblance to PGA, but very different in several aspects. We compare and contrast the characteristics of these two lesions.
Methods
This was a 63-year-old man referred for an upper GI endoscopy for complaints of indigestion, dyspepsia, and weight fluctuation. Endoscopy showed a 13 mm polypoid lesion in the second portion of the duodenum, opposite to and separate from the ampulla. An en-bloc hot snare was used to resect the polyp. Histopathologic examination showed features reminiscent of PGA, namely a complex submucosal proliferation of tightly packed variably dilated glands and villous fronds lined by a monolayer of columnar cells with basally located round nuclei and prominent nucleoli. In contrast, however, the columnar cells in most of the lesion contained abundant mucinous cytoplasm resembling Brunner’s glands as well as areas of prominent paneth cell differentiation. The characteristic amphophilic ground glass cytoplasm of PGAs was only noted in a minor component of the lesion. MUC6 and MUC5AC, immunostains that are typically expressed in PGA, were negative. Additionally, p53 showed a wild-type pattern, beta- catenin showed normal membranous staining, and the Ki-67 index was low.
Results
After review of the literature and expert consultation, we were not able to fully classify this lesion under any documented entity, however, we believe that it could be akin to PGA. Authors hypothesized that PGAs may originate from stem cells within Brunner glands as a response to chronic injury. These cells may then differentiate upwards, forming gastric foveolar metaplasia or downwards giving rise to Brunner gland hyperplasia.
Conclusion
Based on this hypothesis, the proliferating cells are prone to mutations resulting in a hyperplasia/metaplasia to dysplasia sequence that leads to the formation of PGAs or lesions such as the one demonstrated here.

Abstract
Fusarium head blight (FHB) is a devastating disease to cereal crops worldwide that decreases grain yield, grain quality, and causes mycotoxin contamination. FHB resulted in an estimated $2 billion USD loss in the US between 1993 and 2001, and 520 million Canadian dollars (CAD) in Canada in the 1990s. In the wheat producing areas in Canada and the United States, it is perceived that significant progress has been made to manage FHB, but the economic impact of various innovations has not been quantified. Therefore, the main objective of this study was to assess the economic impact of various practices deployed in the province of Ontario, Canada, on managing deoxynivalenol and improving agronomic performance in winter wheat since an epidemic in 1996. The impacts of four hypothetical FHB management scenarios on total deoxynivalenol (DON) concentration and grain yield were estimated in field experiments that compared old (mid-1990s) and modern era (mid-2010s) production practices. Management scenarios included old and new cultivars varying in susceptibility to FHB, fungicide application and nitrogen rates. These impacts were applied to farm survey data collected in 1996 to estimate farm revenue and profit. A similar economic estimate was conducted for the recent FHB epidemic in 2013. If a modern MR cultivar, a modern fungicide, and the combination were deployed in the epidemic of 1996, farm revenue would have increased by 26-32, 23-36 and 48-60%, and profit increased by 88-157, 42-59 and 165-207 CAD per ha, respectively, depending on the nitrogen rate. In the province of Ontario, up to 68 million CAD of revenue losses could have been avoided in 1996 with the use of modern agronomic and FHB management practices. Our study has quantified some of the major economic advances in managing FHB and DON since 1996, but further research is needed to develop better cultivars and management strategies.

Abstract
The stability of polymeric micelles is a key property for anticancer drug delivery. In this study, a novel amphiphilic triblock copolymer, methoxy poly(ethylene glycol)-b-poly(allyl glycidyl ether)-b-poly(ε-caprolactone) (mPEG-b-PAGE-b-PCL), with different hydrophobic lengths was designed and synthesized using the combination of two successive ring-opening polymerizations. The products were characterized using 1H NMR and gel permeation chromatography (GPC). The triblock copolymers could self-assemble into micelles to encapsulate doxorubicin (DOX). The diameter of the DOX-loaded micelles increased from 63 to 92 nm with increasing PCL block length in the copolymer composition. The interface of the mPEG-b-PAGE-b-PCL micelles was crosslinked by a thiol-ene reaction with 1,4-butanedithiol. The stability, drug release and in vitro cytotoxicity of the DOX-loaded micelles were studied. The results showed that the DOX-loaded micelles could be effectively endocytosed by cancer cells and have good antitumor efficacy. In addition, the crosslinked micelles (CLMs) had better tumor accumulation than the noncrosslinked micelles (NCLMs) after intravenous injection using the lipophilic dye DiR.

Abstract
It remains a challenge to develop highly polymer-based nanocomposite thermal interface materials, which can effectively remove heat developed during the miniaturization of electronic instruments. It has been reported that a large number of graphene-based nanocomposites exhibit excellent performance. However, it is still an issue to construct thermal conductive pathways by orientation arrangements with a low filler volume fraction. Herein, a high-thermal conductivity filler of magnetic carbon nanotube-grafted graphene polyhedra (Co@Co3O4-G) was exploited via the annealing of metal–organic frameworks (ZIF-67). Co@Co3O4-G can improve the thermal conductivity of nanocomposites obviously by forming oriented pathways for phonon transport in an external magnetic field. Therefore, the resulting nanocomposite displayed a high thermal conductivity of 2.11 W m−1 K−1 for only 8.7 vol%, which is 10 times higher than that of the pure epoxy resin. Core-shell magnetic cobalt oxide (Co@Co3O4) was encapsulated in situ in the nanoarchitecture to avoid falling off. Moreover, the equilibrium molecular dynamics (EMD) simulation verifies that Co@Co3O4-G had high thermal conductivity to effectively improve the heat dissipation of nanocomposites. This strategy provides an approach for developing high-performance thermal management materials and opens up the possibility for the pioneering applications of encapsulated magnetic-oriented thermal conductive fillers. A high-thermal conductivity filler of magnetic carbon nanotube-grafted graphene polyhedra is exploited via annealing of a metal–organic framework (ZIF-67).![]()

Abstract
Background The main aim of this systematic review was to assess the dry socket management using plasma rich in growth factor (PRGF) in terms of pain relief, alveolar fossa healing, inflammation, the incidence of dry socket.
Material and Methods PubMed, Cochrane Library, Elsevier Science Direct, China Biology Medicine (CBM), China National Knowledge Infrastructure (CNKI) and VIP database were searched for the related articles without language limitation. Two reviewers independently searched and evaluated relevant studies. This review has been registered in the website PROSPERO (CRD42018087252).
Results 28 articles were retrieved on PubMed and 98 on other electronic databases in the initial search. In the end, 4 randomized controlled trials (RCTs) were included, with a total of 139 patients enrolled. The descriptive results indicated that the use of PRGF may help reduce pain and inflammation after tooth extraction. To some extent, it is beneficial to the management of dry socket after extraction.
Conclusions Quality assessment indicated all the included studies were judged to be at high risk of bias with low quality. Hence, it was impossible to make a recommendation for clinical use of PRGF based on the current evidence. Clearly, a multicenter clinical randomized controlled trial is needed urgent to evaluate the safety and efficacy of PRGF for dry socket management. Key words:plasma rich in growth factor, PRGF, dry socket, systematic review.

Abstract
Abstract
Polystyrene-based wood plastic composites (WPCs) containing ammonium polyphosphate (APP) and iron (Fe) powder were prepared in this work by solution blending with the aid of an alternating magnetic field. The mechanical, electrical, thermal and fire performances of the WPCs were analyzed through mechanical testing, thermogravimetry and CONE calorimeter. The addition of Fe powder decreased the tensile strength and increased the impact strength. The APP promoted the formation of sufficient char on the material’s surface and enhanced the flame retardant properties. Furthermore, an alternating magnetic field was used to align the Fe powders. After the magnetic treatment, the electrical conductivity and thermal properties were found to increase considerably compared with those without treatment. The Agari model presented the most reasonable prediction of thermal conductivity as a function of Fe content among three classical thermal conduction models. According to the morphological observations, the iron particles in the composites tended to rearrange along the direction of the magnetic field after treatment, resulting in the enhancement of both thermal and electrical conductivities. The prepared WPCs in this study exhibited good flame retardant properties together with the acceptable mechanical properties of the composites.

Abstract
Colorization for fabricating aluminum pigments has broad application prospects in recent years. In this study, yellow-colored aluminum pigments with the double-layer structure Al@SiO2@PFMV were prepared using a sol-gel method. A crosslinked copolymeric dye (PFMV) was firstly synthesized by radical polymerization using vinyl triethoxysilane (VTES) and a small molecular dye (FGMAC) as monomers. Then, colored aluminum pigments were prepared by hydrolysis and condensation of the copolymers on the surface of aluminum pigments. SEM, AFM, FTIR, and XPS were used to characterize the surface morphology and chemical structure of the colored aluminum pigments. It was found that the colored aluminum pigments have a heterogeneous and smooth surface layer. The anticorrosion results showed that the colored aluminum pigments had better chemical stability with significantly improving corrosion resistance compared to raw aluminum pigments and Al@SiO2 with the single-layer coating. Chromatism analysis indicated that the lightness of Al@SiO2@PFMV pigments decreased slightly and the color changed from silver-gray to yellow.

Abstract
Boronic acid copolymers with a large number of functional groups were obtained via a free radical polymerization method. The corresponding composite membranes for alkaline diffusion dialysis (DD) were prepared by a crosslinking reaction between polyvinyl alcohol (PVA) and the as-obtained boronic acid copolymers. The composite membranes possessed water uptake (WR) of 122.1–194.4%, ion exchange capacities (IECs) of 0.79–1.17 mmol/g, as well as both good mechanical stability (tensile strength of 40.7–49.9 MPa and elongation at break of 52.1–121.1%) and thermal stability. The as-prepared membranes were stable in 2 M NaOH solution at 65 °C with a swelling degree and mass loss of as-prepared membranes in the range of 305–368% and 9.2–22%, respectively. A NaOH/Na2WO4 mixture was used to investigate the separation properties of as-prepared membranes via the DD process. Results indicated that the dialysis coefficients of OH− (UOH) were in the range of 0.0079–0.0150 m/h, while the separation factors (S) were in the range of 26.6–53.2. The functional groups from boronic acid copolymer and –OH from PVA were demonstrated to promote the ion transport synergistically.

Abstract
OBJECTIVE The objective of the present study was to explore the significance of human β-defensin 3 (HBD-3) through establishment and evaluation of the model of implant-related biofilm infection of the femoral condyle of the outer knee using Sprague-Dawley (SD) rats. MATERIALS AND METHODS Age-matched SD rats were divided into three groups, the HBD-3 group, HBD-3 fluorescent liposome group, and the HBD-3 liposome-microbubble fluorescent composite carrier group. After biofilm infection for 24 h, the fluorescent composite vector was injected intraperitoneally 2 times/day. After the first injection, rats in each group were sacrificed on the 7th, 14th, and 28th day. The lower end of the femur bone was harvested after removing the surrounding soft tissue. H&E and immunohistochemical staining were applied and light microscopy was used for observation. Fluorescent markers including tetracycline and calcein were used to follow the formation of new bone in vivo. Undecalcified specimens were embedded in epoxy resin (thickness of roughly 150 m), and confocal microscopy was used for observation. RESULTS By assessing cell proliferation with cell counting kit-8, the proliferation ability of cells in the HBD-3 liposome-microbubble fluorescent composite carrier group was significantly increased compared with the other groups (p<0.05). qPCR was used to measure the levels of alkaline phosphatase (ALP), type I collagen, osteocalcin (OCN), osteopontin (OPN), and bone sialoprotein (BSP) in each group. The levels of these genes in the HBD-3 liposome-microbubble fluorescent composite carrier group were significantly higher than those in other groups (p<0.05). CONCLUSIONS The application of the HBD-3 liposome-microbubble fluorescent composite carrier can significantly promote osteogenesis in rats infected with Staphylococcus aureus, and increase the expression levels of ALP, type I collagen, OCN, OPN, and BSP.

Abstract
Numerous studies have investigated the distribution of methylenetetrahydrofolate reductase (MTHFR) C677T and A1298C polymorphisms and their associations with diseases in China. In this study we conducted a systematic review and meta-analysis of these studies (715 eligible studies in total).Results revealed that the frequencies of the MTHFR C677T and A1298C polymorphisms varied markedly in different areas and ethnicities, and even showed geographical gradients. The MTHFR C677T polymorphism was significantly associated with 42 clinical disorders (p < 0.05), mostly relating to the diseases of circulatory system, birth defects and cancers. The association of the A1298C polymorphism with three diseases (coronary heart disease, breast cancer and neural tube defects fathers) was statistically significant (p < 0.05). However, according to the Venice criteria, only the associations of the C677T polymorphism with breast and ovarian cancers were assessed as having strong epidemiological credibility. This is the first study to provide a comprehensive assessment of the current status and gaps in genetic epidemiological study of the two polymorphisms in China, and its findings may be useful for medical and public health practices. Future studies are warranted to focus on the interactions of MTHFR genes with environmental exposure and with other genes, and to improve their methodological quality and reporting of findings.
