The objective of the present study provides further data comparing retention, marginal integrity and caries preventive effects of two fissure sealants (glass ionomer based; GC Fuji VII Capsule [Fuji VII] and ormocer based; Admira Seal [AS]) in children. This study was designed as a randomized single-blind clinical trial. The permanent first molars (PFMs) of 50 children, 7-13 years of age (mean age: 8.9<1.3 years), were sealed with a split-mouth design. Fissure sealants applied to the PFMs according to the manufacturer's recommendations by one pediatric dentist. Clinical evaluation of the sealants was carried out to record retention, marginal integrity and presence of caries at 6, 12, 18 and 24 months after placement by the other pediatric dentist. Kaplan-Meier survival analysis and Cox's regression models were used to estimate the probability of two sealants success. Results: Alpha and Bravo retention rates at the end of follow-up were 13% and 80% for Fuji VII and 3% and 83% for AS, respectively. For retention and marginal integrity between fissure sealants was found similar survival rates (p>0.05). After 24 months, presence of caries was 16% for Fuji VII and 32% for AS (p<0.05). Conclusion: Fuji VII and AS exhibited similar retention and marginal integrity during 24 months. However, Fuji VII was showed better results than AS for caries preventive effect. Consequently, Fuji VII sealants may be a better choice for preventing occlusal caries.

Glass ionomer cements possess several properties that support their consideration in a wide variety of clinical applications including Pit and fissure sealants. The aim of this study was to compare and evaluate Fuji III and Fuji VII glass ionomer sealants in terms of retention, caries incidence and salivary fluoride release between two groups of children aged 6 and-8 years respectively. One hundred and ten first permanent molars were sealed and the clinical evaluation showed no incidence of caries. There was partial or complete retention of the sealant in 80% of the treated teeth in both groups at the one-year evaluation. Irrespective of the sealant used, the pattern of fluoride release remained consistent, with an initial high fluoride release followed by low prolonged leakage before returning to baseline value at the end of one year.

Introduction: As one of the most important dental diseases, caries cannot be treated with classic therapeutic measures, but very often, there is a need for preventive and prophylactic measures. Aim: The aim of this study was to assess clinical efficiency of composite materials and glass-ionomer cements as pit and fissure sealants in caries prevention. Materials and Methods: The study comprised 50 patients (141 teeth), both sexes, 6-7 years old with at least two erupted first permanent molars. The main diagnostic criterion was smooth enamel surface with no probe faltering on the tooth. Materials tested in this study were two composite materials (Heiloseal-Opak and Helioseal-Transparent) and two glass-ionomers (Fisurit and Fuji VII). For clinical assessment of these materials, modified Cvar-Ryge criteria were used. Results: The obtained results showed no statistically significant differences among materials in respect to retention, marginal adaptation, discoloration and secondary caries. The difference was significant in respect to surface roughness between Fuji VII and Fisurit and Fuji VII and Helioseal-Opak (p<0.05). Conclusion: Composite sealant Heiloseal-Opak and glass-ionomer Fuji VII showed better clinical results in respect to all tested parameters compared to Helioseal-Transparent and Fisurit. .

Abstract Aim The anatomical pits and fissures of the teeth have long been recognized as susceptible areas for the initiation of dental caries. The extreme vulnerability to decay of these pits and fissures on the occlusal surfaces has prompted dental scientists to seek methods of caries prevention. Motivated by the role of pit and fissure sealants in caries prevention, the aim of this study was to compare the efficacy of Fuji VII® glass ionomer sealant and Concise® resin-based sealant. Methods and Materials An in vitro study was undertaken using forty premolars extracted for orthodontic reasons. The teeth were divided into two groups and sealants were applied. One was an experimental group using Fuji VII® as a pit and fissure sealant and the other a control group using Concise®. The teeth were kept in gentian violet dye for 24 hours, the sectioned samples were observed for the extent of dye penetration, and scores were based on established scoring criteria. Results The comparison of the performance of the two groups showed a statistically significant difference. Conclusion The Concise® resin-based sealant performed better in terms of sealing ability than did the Fuji VII® glass ionomer sealant. Citation Ganesh M, Shobha T.

Objectives: Fluoride release/recharge properties of fissure sealants are important for their longterm inhibition of caries. This study was conducted to examine the relationship between fluoride release and recharge of pit-and-fissure sealants.Methods: Specimens were prepared from 5 different sealant materials: Fissurit F, a conventional resin; Fuji VII, a glass-ionomer cement (GIC); Fuji II LC, a resin-modified GIC; Ionosit, a polyacidmodified composite resin (PMRC); and Aelite Flo, a flowable composite resin. Specimens stored in a polyethylene test tube containing 5.0 ml ultrapure water. On day 21, specimens were exposed to 1.23% APF gel. Fluoride release was measured using a fluoride-specific ion electrode at 1-7, 14, 21, 22, 28, 35 and 42 days.Results: The glass-ionomer based sealants Fuji VII and Fuji II LC had significantly higher fluoride release than the other materials at all times tested (P<.05). Fluoride release of all materials tested increased following exposure to APF gel (P<.05).Conclusions: Within the limitations of this short-term study, glass ionomer-based sealants were shown to have higher initial fluoride release as well as higher fluoride recharge capacity than other sealants.

In view of the need for aesthetics, restorations of teeth will typically be completed using tooth colored restorative materials. With the advent of biomimetic restorative materials, such as glass ionomer cements (GIC), much greater emphasis is now being placed on how well such materials can resist the challenge of acids that are present in foods and drinks, or gastric contents that are regurgitated. This laboratory study compared the dissolution and behavior of five GIC materials (GC Fuji® VII, GC Fuji® Bulk, GC Fuji® IX Fast, Fuji® IX Extra and GC Equia® Forte Fil) when exposed to three acids (citric acid, phosphoric acid and lactic acid), versus ultrapure deionized water, which was used as a control. Discs of each material GIC were submerged in solutions and percentage weight changes over time determined. Subsequently, the GIC materials were also placed as a part of standardized Class II sandwich restorations in bovine teeth (n = 20), and submerged in the solutions, and the extent of GIC dissolution and protection of the adjacent tooth was scored. Weight loss increased with time and with acid concentration. Overall, the most soluble material was GC Fuji® IX Extra, while GC Fuji® IX Fast and GC Fuji® Bulk were less soluble, and the least soluble material was GC Equia® Forte Fil. The most destructive solution for both the discs and for GIC restorations in teeth was 10% citric acid, while the least destructive acid was 0.1% lactic acid. The more recent GIC materials GC Fuji® Bulk and GC Equia® Forte Fil showed increased acid resistance over the older GIC materials, and this further justifies their use in open sandwich Class II restorations in more hostile environments.

>Purpose: To compare the occlusal and gingival microleakage of Class-II composite restorations utilizing etch-and-rinse and self-etch adhesives and different liner materials in primary and permanent teeth. Study design: Standardized class-II cavities were prepared in freshly-extracted sound primary and permanent molars (n=80/each), with all cavosurface margins involving enamel. The main experimental groups were; A. Single Bond 2/primary teeth; B. Adper SE Plus/primary teeth; C. Single Bond 2/permanent teeth; and D. Adper SE Plus/permanent teeth. Each group comprised 4 subgroups (n=10/each) with respect to the liner material employed (n=10/subgroup): 1. Fuji VII; 2. Fuji Triage; 3. Filtek Supreme XT Flowable Composite, and 4. No liner. All teeth were restored with Filtek Supreme XT Universal Nanofilled Composite. Following thermocycling and immersion in basic fuchsin, the extent of microleakage was measured on crown sections using image analysis. The data were analyzed with Wilcoxon Signed Ranks Test, Mann-Whitney U-Test and Kruskal-Wallis One-Way ANOVA at ?=0.05. Results: In both primary and permanent teeth the use of etch-and-rinse adhesive resulted in similar occlusal and gingival microleakage values (p>0.05). As for the self-etch adhesive, similar results were observed (p>0.05) with the exception of significantly less occlusal leakage in the Fuji Triage VII and Fuji Triage subgroups of primary teeth than those of permanent teeth (pÃ0.05). When the effects of liner material and the type of adhesive were disregarded, significantly more gingival microleakage was observed in primary teeth than in permanent teeth (pÃ0.01), while the occlusal microleakage values were similar (p>0.05). Irrespective of the tooth type and adhesive material, comparison of subgroups containing a liner material with those without one revealed no significant differences for both occlusal and gingival microleakage values (p>0.05). Conclusions: Occlusal microleakage was similar in both primary and permanent teeth, while a lesser extent of gingival seal was observed in primary teeth. Overall, placement of a liner material did not improve resistance to microleakage.

Neutronic analysis on the Molten Salt Reactor FUJI-12 using the fissile material 235U in LiF-BeF2-UF4 has been carried out. The problem faced in the use of thorium-based fuel is that the amount of 233U is small and not available in nature. 233U was produced through the 232Th breeding at a cost of $46 million/kg. That is a very high price when compared to 235U enrichment, which is only $100/kg. The MSR FUJI-12 used in this study is a generation IV reactor with a mixture of liquid salt fuel LiF-BeF2-ThF4-UF4 and thorium-based fuel (232Th+233U). In this study, neutronic analysis was carried out by replacing thorium-based fuel with uranium-based fuel (235U+238U). Neutronic analysis was performed using the OpenMC 0.13.0 code, which is a Monte Carlo simulation-based neutron analysis code. The nuclear data library used for neutronic calculations is ENDF B-VII/1. The fuel is used in a LiF-BeF2-UF4 molten salt mixture with three eutectic compositions: fuel 1, fuel 2, and fuel 3. Each fuel composition is optimized by enriching 235U in UF4 by 3 % to 8 %. The optimization results show the stability of the reactor criticality value, which is the main parameter so that the reactor can operate for the specified time. The optimization results show that fuel 1 cannot reach its optimal state in each variation of 235U enrichment. Fuel 2 and fuel 3 can reach optimal conditions at a minimum enrichment of 8 % and 7 % 235U. The results of the analysis of the distribution of the neutron flux in the reactor core show the distribution of nuclear reactions that occur in the core. The distribution of flux values in fuel 1 shows that the fission chain reaction is not running perfectly. Fuel 2 and fuel 3 are more stable by maintaining maximum flux at the center of the reactor core.

Abstract: Glass ionomer cement (GIC) is a restorative material used in child dental care with anti-cariogenic properties and fluoride release. However, this GIC has some disadvantages, such as high solubility due to acid particles that can cause surface roughness. Children at a young age typically drink milk, such as Ultra High Temperature (UHT) milk or soy milk which may affect the restorative material. This study aimed to evaluate the surface roughness of GIC immersed in UHT milk, soy milk, and artificial saliva. This was an experimental laboratory study. Samples were GICs (GC Fuji VII, Japan) in a cylindrical shape with a diameter of 10 mm and a thickness of 2 mm. A total of 18 samples were divided into three groups, one group (n=6) was immersed in UHT milk, and the other two groups were immersed in soy milk and artificial saliva. The samples were tested using a surface roughness tester (Surtronic S-128) that was reviewed before and after immersion. The results showed that the surface roughness value of GIC was increased after being immersed in UHT milk (0.12±0.02), soy milk (0.12±0.06), and artificial saliva (0.06±0.03). The Kruskal Wallis test showed no significant difference in surface roughness of GICs immersed in the three groups. In conclusion, UHT milk and soy milk did not significantly affect the surface roughness of GICs.Keywords: glass ionomer cement; surface roughness; UHT milk; soy milk Abstrak: Semen ionomer kaca (SIK) merupakan bahan restorasi pada perawatan gigi anak yang memiliki sifat antikariogenik dan dapat melepaskan fluoride.

Aim: The purpose of this in vivo study was to compare the effectiveness of a new light cured resin based dicalcium/tricalcium silicate pulp capping material (TheraCal LC, Bisco), pure Portland cement, resin based calcium hydroxide or glass ionomer in the healing of bacterially contaminated primate pulps. Study design: The experiment required four primates each having 12 teeth prepared with buccal penetrations into the pulpal tissues with an exposure of approximately 1.0 mm. The exposed pulps of the primate teeth were covered with cotton pellets soaked in a bacterial mixture consisting of microorganisms normally found in human pulpal abscesses. After removal of the pellet, hemostasis was obtained and the pulp capping agents applied. The light cured resin based pulp capping material (TheraCal LC) was applied to the pulpal tissue of twelve teeth with a needle tip syringe and light cured for 15 seconds. Pure Portland cement mixed with a 2% Chlorhexidine solution was placed on the exposed pulpal tissues of another twelve teeth. Twelve additional teeth had a base of GIC applied (Triage, Fuji VII GC America) and another twelve had a pulp cap with VLC DYCAL (Dentsply), a light cured calcium hydroxide resin based material. The pulp capping bases were then covered with a RMGI (Fuji II LC GC America). The tissue samples were collected at 4 weeks. The samples were deminerilized, sectioned, stained and histologically graded. Results: There were no statistically significant differences between the groups in regard to pulpal inflammation (H= 0.679, P=1.00). However, both the Portland cement and light cured TheraCal LC groups had significantly more frequent hard tissue bridge formation at 28 days than the GIC and VLC Dycal groups (H= 11.989, P=0.009). The measured thickness of the hard tissue bridges with the pure Portland and light cured TheraCal LC groups were statistically greater than that of the other two groups (H= 15.849, P=0.002). In addition, the occurrence of pulpal necrosis was greater with the GIC group than the others. Four premolars, one each treated according to the protocols were analyzed with a microCT machine. The premolar treated with the light cured TheraCal LC demonstrated a complete hard tissue bridge. The premolar treated with the GIC did not show a complete hard tissue bridge while the premolar treated with VLC Dycal had an incomplete bridge. The pure Portland with Chlorhexidine mixture created extensive hard tissue bridging. Conclusion: TheraCal LC applied to primate pulps created dentin bridges and mild inflammation acceptable for pulp capping.

Introduction: In contemporary preventive dentistry there are numerous experimental in vitro and clinical studies on the growing number of materials for sealing pits and fissures. Aim: the aim of this study was to evaluate the impact of occlusal tooth morphology on penetrating abilities of two types of fissure sealants and measure the unfilled space at the bottom of occlusal groove using scanning electron microscopy (SEM). Materials and methods: The sample consisted of 10 freshly extraced intact premolars and 10 molars randomly divided into 4 groups. In group I (5 premolars), and group II (5 molars) glass ionomer Fuji VII was used as fissure sealant, while in groups III (5 premolars) and IV (5 molars) resin-based sealant (Helioseal-F) was used. Six sections of each tooth were prepared for SEM. Sealant penetration was observed at 30x magnification and the unfilled space at the bottom of the groove at 500x. Sealant penetration in relation to the absolute depth of occlusal grooves was recorded and the unfilled space beneath the sealant was expressed through its greatest diameter. Results were statistically analyzed using ?2 test. Results: There was no statistically significant difference in penetration ability and the unfilled space between tested materials or teeth groups. The average depth of penetration for glass ionomer was 83% and for resin-based sealant 81% of fissure depth. Mean diameters of the unfilled space beneath the sealants were 95 ?m (glass ionomer) and 93 ?m (resin-based sealant). Shallower penetration of both sealing materials was observed in deep pits and fissures with greater diameter of unfilled space (p<0.05). Conclusion: Based on results of the present study it can be concluded that penetration of contemporary fissure sealants largely depends on occlusal tooth anatomy.

One of the most efficient prophylactic measures in caries prevention is sealing pits and fissures. After improvements of physical and mechanical properties, glass-ionomers are frequently used as sealing materials. The aim of this study was to evaluate the prophylactic efficiency of Fuji VII, a glass-ionomer fissure sealant, through adaptation ability and fluoride reeasing potential assessment using scanning electron microscopic and energy dispersive spectroscopic techniques. The sample consisted of 20 extracted intact human teeth, 10 premolars and 10 molars. Six sections of each tooth were analyzed using SEM. EDS analysis was conducted one week and three months after material placement. The parameters used for the evaluation included: adaptation ability, penetration depth, material structure, integrity of the interfacial zone and ion exchange extent. The sealant penetration depth was observed at 30 X magnification, and the interfacial zone between the material and the enamel at 500-10000 X. EDS was used for quantitative analysis of the material structure, interfacial zone and the enamel surface. The results were statistically analyzed the using chisquare test and descriptive statistical methods. SEM analysis revealed the zone of interaction between the enamel surface and the glass-ionomer with predominant cohesive failures within the sealant material, and satisfactory adaptation ability of the sealing material. The mean value of the penetration was 83% of the total fissure depth, without a statistically significant difference between the tested teeth groups. A lower penetration ability was observed in deep pits and fissures with a larger diameter of unfilled space (p<0.05). EDS analysis revealed the potential of the glass-ionomer for ion exchange with dental tissues. The presence of fluoride ions was detected in 2 sections 3 months after material placement. Glass-ionomers, chemically cured, biocompatible materials demonstrate satisfactory prophylactic characteristics.

ABSTRACT Objectives Fluoride plays a pivotal role in oral health promotion and is the corner stone in the prevention of dental caries. The purpose of this study was to evaluate the effects of temperature, time interval and storage conditions on fluoride release by three commercial glass ionomer cements (GIC). Materials and Methods Three commercial glass ionomers: GC Gold Label Universal Restorative (conventional), GC Gold Label Light-Cured Universal Restorative and GC Fuji VII (GC Corporation, Tokyo, Japan) were used to investigate fluoride release. The 6 × 2 mm disk-shaped specimens prepared from each material were immersed in distilled water or artificial saliva at temperatures 4°C, 37°C or 55°C. The amount of fluoride release from these specimens was studied for the period of 1, 7, 14 and 28 days with the help of fluoride selective ion electrode. Results The amount of fluoride release was significantly (p < 0.001) high in distilled water when compared to artificial saliva in all the three types of GIC studied. The highest level of fluoride release was observed on the first day of the study, followed by days 7 and 14, with least release on days 28. It was also observed that at 55°C, the amount of fluoride release was significantly (p < 0.001) high in all three GIC. However, there was no significant difference among the three GIC studied. Conclusion The amount of fluoride release depends on temperature, time interval and storage condition. The result from the study concludes that GIC in the oral cavity serve as fluoride reservoir and contribute a low fluoride release in oral fluids. Clinical significance The clinical use of GIC that release fluoride is relevant mainly in patients at risk of or with caries activity, thereby preventing initiation of secondary caries and failure of restorations. It may also be important in developing regimes for improving the delivery of tropical fluoride products. This study would be helpful to make some considerations about clinical indication and longevity of restorative materials studied. How to cite this article Madhyastha P, Kotian R, Pai V, Khader AMA.

"Synthetic dietary inulin, Fuji FF, delays development of diet-induced obesity by improving gut microbiota profiles and increasing short-chain fatty acid production."

Background Dietary fiber, including inulin, promotes health via fermentation products, such as short-chain fatty acids (SCFAs), produced from the fiber by gut microbiota. SCFAs exert positive physiological effects on energy metabolism, gut immunity, and the nervous system. Most of the commercial inulin is extracted from plant sources such as chicory roots, but it can also be enzymatically synthesized from sucrose using inulin producing enzymes. Studies conducted on rodents fed with a cafeteria diet have suggested that while increasing plasma propionic acid, synthetic inulin modulates glucose and lipid metabolism in the same manner as natural inulin. Therefore, this study aimed to determine the effects of a synthetic inulin, Fuji FF, on energy metabolism, fecal SCFA production, and microbiota profiles in mice fed with a high-fat/high-sucrose diet. Methods Three-week-old male C57BL/6J mice were fed a high-fat/high-sucrose diet containing cellulose or Fuji FF for 12 weeks, and the effects on energy metabolism, SCFA production, and microbiota profiles were evaluated. Results Body weight gain was inhibited by Fuji FF supplementation in high-fat/high-sucrose diet-fed C57BL/6J mice by reducing white adipose tissue weight while increasing energy expenditure, compared with the mice supplemented with cellulose. Fuji FF also elevated levels of acetic, propionic and butyric acids in mouse feces and increased plasma propionic acid levels in mice. Moreover, 16S rRNA gene amplicon sequencing of fecal samples revealed an elevated abundance of Bacteroidetes and a reduced abundance of Firmicutes at the phylum level in mice supplemented with Fuji FF compared to those supplemented with cellulose. Fuji FF also resulted in abundance of the family Bacteroidales S24-7 and reduction of Desulfovibrionaceae in the feces. Conclusion Long term consumption of Fuji FF improved the gut environment in mice by altering the composition of the microbiota and increasing SCFA production, which might be associated with its anti-obesity effects.

AbstractKnown locally as the water mountain, for millennia Japan’s iconic Mt Fuji has provided safe drinking water to millions of people via a vast network of groundwater and freshwater springs. Groundwater, which is recharged at high elevations, flows down Fuji’s flanks within three basaltic aquifers, ultimately forming countless pristine freshwater springs among Fuji’s foothills. Here we challenge the current conceptual model of Fuji being a simple system of laminar groundwater flow with little to no vertical exchange between its three aquifers. This model contrasts strongly with Fuji’s extreme tectonic instability due to its unique location on top of the only known continental trench–trench–trench triple junction, its complex geology and its unusual microbial spring water communities. On the basis of a unique combination of microbial environmental DNA, vanadium and helium tracers, we provide evidence for prevailing deep circulation and a previously unknown deep groundwater contribution to Fuji’s freshwater springs. The most substantial deep groundwater upwelling has been found along Japan’s most tectonically active region, the Fujikawa-kako Fault Zone. Our findings broaden the hydrogeological understanding of Fuji and demonstrate the vast potential of combining environmental DNA, on-site noble gas and trace element analyses for groundwater science.

The retention force of cemented crowns on implant abutments with various luting materials was evaluated. Cobalt–chromium crowns were cemented onto tapered titanium abutments (Camlog) with eugenol-free temporary cement (RelyX TempBond NE), composite-based temporary cement (Bifix Temp), zinc phosphate cement (Harvard Cement), glass-ionomer cements (Meron, Fuji I), and resin-modified glass-ionomer cements (Fuji II, Fuji Plus, Ketac Cem Plus). Specimen aging via hydrostress was performed in artificial saliva at 37 °C for 14 days (S1), followed by hydrothermal stress with thermocycling (S2). The crowns were removed, and the force was recorded (T1). Subsequently, the crowns were recemented, aged, and removed, and the force was recorded (T2, T3). The retention forces differences were statistically significant according to the storage conditions at T1 (p = 0.002) and T3 (p = 0.0002). After aging (S1), Ketac Cem Plus had the highest retention force median value difference (T3 versus T1) (−773 N), whereas RelyX TempBond NE had the lowest (−146 N). After aging (S2), Meron had the highest retention force median value difference (−783 N), whereas RelyX TempBond NE had the lowest (−168 N). Recementation decreased the retention force of the implant-supported cobalt–chromium crowns cemented and recemented with the same luting materials. Luting materials (at T1) and aging conditions significantly impacted the retention force.

Fine-grained urban flow inference (FUFI) aims to infer the coarse-grained (CG) urban flow map to the corresponding fine-grained (FG) one, which plays an important role in efficient traffic monitoring and management in smart cities. In FUFI, the CG map can be obtained with only a small number of monitoring devices, greatly reducing the overhead of deploying devices and the costs of maintenance, labor, and electricity. Existing FUFI methods are mainly based on techniques from image super-resolution (SR) models, which cannot fully consider the influence of external factors and face the ill-posed problem in SR tasks. In this paper, we propose UFI-Flow, a novel approach for addressing the FUFI problem by learning the conditional distributions of CG and FG map pairs. Given the CG map and the latent variables, the corresponding FG map is inferred by invertible transformations. In addition, an augmented distribution fusion mechanism is further proposed to constrain the urban flow distribution within the influence of external factors. We provide a new large-scale real-world FUFI dataset and show that UFI-Flow significantly outperforms the strong baselines.

Apple core rot, an economically important disease worldwide, appears both before and during harvest. Current gaps in understanding of the infection cycle impede progress toward more effective management of this disease. The fungus Trichothecium roseum is the main pathogen of core rot on apple in China. In this study, we used fluorescent labeling to trace colonization of T. roseum in floral tissues, characterizing routes of penetration to the core of ‘Fuji’ apples. T. roseum infected petals, anthers, filaments, stigmas and separated styles of flowers, and floral debris served as inoculum for core infection. In field inoculations, T. roseum entered styles initially through stylar fissures and colonized pluricellular hairs of these fissures during early stages of fruit development. Subsequently, hyphae grew along the extending fissures, which are continuations of stylar fissures located between stylar bases and carpel cavities. The hyphae remained in the extending fissures from mid-June to late July. When fruit developed an open sinus in late July, the sinus eventually fused with extending fissures and carpel cavities in late August, hyphae invaded carpel cavities, and ultimately fruit flesh via cracks on carpel cavity walls. Our results revealed for the first time the routes by which T. roseum penetrates apple fruit, and provided significant insights for strategic management of core rot.

Abstract This paper presents a frame-based constructional approach to argument structure satisfaction via unselected adjuncts, by focusing on one such case in Japanese. It points out an intriguing constructional phenomenon whereby causal adjunct clauses marked with node ‘because’, as used with main-clause predicates that evoke communication frames (such as Telling and Warning), serve to satisfy main-clause argument structure. The node clause precedes the main-clause speech act of telling/warning, and can be interpreted as a speech-act causal (Sweetser 1990). The node clause at the same time conveys the content of informing or warning, i.e., the core Frame Element message, which is absent as a main-clause complement. This analysis of argument structure satisfaction via unselected adjuncts provides evidence for a Frame Semantic approach to argument structure that incorporates Construction Grammar.

O presente trabalho resgata a importância de Sabina Spielrein, uma das primeiras mulheres da história da psicanálise, recordando sua trajetória biográfica e proposições sobre o conceito de pulsão de morte, e examinando contribuições à compreensão freudiana relativa a esse conceito. As principais referências foram textos de Spielrein e de Freud e documentos históricos, como as cartas trocadas entre Freud, Jung e Spielrein, o diário pessoal da autora e as “Atas da Sociedade Psicanalítica de Viena”. Percebemos que há entre Freud e Spielrein uma trajetória de questões semelhantes acerca da psicose, que fomenta o estudo da pulsão de morte. O artigo assinala que ambos valeram-se do pensamento biológico para suas proposições e que apresentam considerações semelhantes sobre o sadismo e o masoquismo. Quanto à pulsão de morte, para Freud trata-se de pulsão que objetiva a redução absoluta das tensões, conduzindo o ser vivo de volta ao estado inorgânico pela via do desligamento e da destruição. Para Spielrein, a pulsão de morte está oculta na pulsão sexual e, apesar de visar à destruição, objetiva a transformação, morte para o antigo e vida para o que vai surgir.

Radix Aconiti Lateralis Preparata (fuzi) is the processed product of Aconitum carmichaelii Debeaux tuber, and has great potential anti-myocardial infarction effects, including improving myocardial damage and energy metabolism in rats. However, the effects of Radix Aconiti Lateralis Preparata extracts in a rat model of myocardial infarction have not yet been fully illustrated. Herein, Radix Aconiti Lateral Preparata was used to prepare Radix Aconiti Lateralis Preparata extract (RAE), fuzi polysaccharides (FPS), and fuzi total alkaloid (FTA). Then, we aimed to compare the effects of RAE, FPS, and FTA in MI rats and further explore their influence on small molecules in the heart. We reported that Radix Aconiti Lateralis Preparata extract (RAE) and fuzi total alkaloid (FTA) significantly improved left ventricular function and structure, and reduced myocardial damage and infarct size in rats with myocardial infarction by the left anterior descending artery ligation. In contrast, fuzi polysaccharides (FPS) was less effective than RAE and FTA, indicating that alkaloids might play a major role in the treatment of myocardial infarction. Moreover, via matrix-assisted laser desorption/ionization–mass spectrometry imaging (MALDI–MSI), we further showed that RAE and FTA containing alkaloids as the main common components regulated myocardial energy metabolism-related molecules and phospholipids levels and distribution patterns against myocardial infarction. In particular, it was FTA, not RAE, that could also regulate potassium ions and glutamine to play a cardioprotective role in myocardial infarction, which revealed that an appropriate dose of alkaloids generated more obvious cardiotonic effects. These findings together suggested that Radix Aconiti Lateralis Preparata extracts containing an appropriate dose of alkaloids as its main pharmacological active components exerted protective effects against myocardial infarction by improving myocardial energy metabolism abnormalities and changing phospholipids levels and distribution patterns to stabilize the cardiomyocyte membrane structure. Thus, RAE and FTA extracted from Radix Aconiti Lateralis Preparata are potential candidates for the treatment of myocardial infarction.

Purpose – The purpose of this paper is to determine the development and knowledge flows of dye-sensitized solar cells (DSSCs) via the use of patent inventor database. Moreover, this study aims to explore patentees and inventors’ companies to help readers and practitioners to be able to understand the patentees, technology development and activities of knowledge flows from four countries. DSSCs, which are known as one of the key technologies of green energy, have been applied ever more widely to many different industries, and their use has quickly grown with a number of scientific publications and patent applications. Design/methodology/approach – This paper was based on the US patent database collection of third-generation DSSCs in four typical countries such as USA, Japan, Germany and Taiwan to map the knowledge network of DSSC technology via the social network analysis method. Findings – The knowledge network of 132 DSSC patents was explored. Among the four countries, Japan leads, with the main patent number being H01G009. This paper also indicates the knowledge flow situation of Japanese inventors of DSSCs. For example, patented inventors Wariishi and Koji (JP) served the Fuji Photo Film Co., Ltd. (JP) in 2002, and then in 2008, transferred to the Fuji Film Corporation (JP). This means that the knowledge of technology was transferred by people who moved to another company for a new job. Research limitations/implications – This study is based on US Patent and Trademark Office patent database to do exploration. Practical implications – This study was expected to provide information for the industry, government and academia, so that they will understand the trajectory of the technology inventor, specialist cultivation and technology development in the DSSC industry. Originality/value – This study provides useful information for the green energy industry, government and academia to understand the importance of the knowledge flows and future development of DSSC technology of the solar cell industry. Thereby, they can intensify industrial competence and innovation by externally collaborating in this field as well as to increase the industrial competence by reimbursing the funds from government and other research institutes.

With the continuous innovation and development of technologies for breeding varieties of fruits, there are more than 8000 varieties of apples in existence. The accurate identification of apple varieties can promote the healthy and stable development of the global apple industry and protect the breeding property rights of rights-holders. To avoid economic losses due to the improper identification of varieties at the seedling-procurement stage, this paper proposes the classification of varieties using images of apple leaves in conjunction with the network models of traditional classification methods, supplemented with deep-learning methods, such as AlexNet, VGG, and ResNet, to account for their shortcomings in robustness and generalizability. We used the Multi-Attention Fusion Convolutional Neural Network (MAFNet) classification method for apple leaf images. The convolutional block distribution pattern of [2,2,2,2] is used to drive the feature extraction layer to have a symmetric structure. According to the characteristics of the dataset, the model is based on the ResNet model to optimize the feature extraction module and integrate a variety of attention mechanisms to achieve the weight distribution of channel features, reduce the interference information before and after feature extraction, complete the accurate extraction of image features, from low-dimensional to high-dimensional, and finally obtain the apple classification results through the Softmax function. The experiments were conducted on a mixture of leaves from 30 apple varieties at 2 growth stages: tender and mature. A total of 14,400 images were used for training, 2400 for validation, and 7200 for testing. The model’s classification accuracy was 98.14%, which improved the accuracy and reduced the classification imputation time as compared with the previous model. Among them, the accuracy rate of “Red General”, “SinanoGold”, and “Jonagold” reached 100%, and the accuracy rate of the bud variant of the Fuji line (“Fuji 2001”, “Red General”, “Yanfu 0”. and “Yanfu 3”) also had an accuracy rate of over 90%. The method proposed in this paper not only significantly improves the classification accuracy of apple cultivars, but it also achieves this with a low cost and a high efficiency level, providing a new way of thinking and an essential technical reference for apple cultivar identification by growers, operators, and law enforcement supervisors in the production practice.

This work is to consider Furuta type inequalities and their applications. Firstly, some Furuta type inequalities underA≥B≥0are obtained via Loewner-Heinz inequality; as an application, a proof of Furuta inequality is given without using the invertibility of operators. Secondly, we show a unified satellite theorem of grand Furuta inequality which is an extension of the results by Fujii et al. At the end, a kind of Riccati type operator equation is discussed via Furuta type inequalities.

In apple cultivation, dwarf rootstocks are chosen for dense planting and intensive cultivation, which is beneficial to production management. Dwarf rootstocks are widely used in apple production in China. However, the dwarfing mechanisms of dwarf interstock are still unclear. Here, M9 and SH40 were selected as the dwarf interstocks for potted Fuji apples. The key transcription factor MdWRKY24 was screened via transcriptional sequencing. The open reading frame sequence of the MdWRKY24 gene was 657 bp in length, encoded 218 amino acids, and was located on the cell membrane. The MdWRKY24-overexpressing Arabidopsis line showed a dwarf phenotype and delayed flowering. The DELLA protein RGA-like (RGL) gene is a repressor of the gibberellin signaling pathway. Yeast two-hybrid analysis revealed that MdWRKY24 could interact with MdRGL1/2/3. The results indicated that MdWRKY24 might affect plant dwarfing through the synergistic effect of MdRGL1/2/3.

Antitranspirant N-2001 (10%), Great Lakes Chemical Corporation, was applied as a soil drench to `Fuji'/EMLA7' apple plants growing in 15 cm pots in a 25/22±3°C (D/N) greenhouse. After bringing pots to field capacity, chemical application was made and water was withheld thereafter. One hour after chemical application, stomatal conductance of treated and control plants was 0.25 and 0.70 cm/sec, respectively. Stomatal conductance of treated plants was maintained at approximately 0.25 cm/sec throughout the test period (28 days). Stomatal conductance of the control plants decreased to 0.25 cm/sec 13 days after treatment due to desiccation. The stem xylem water potential of the treated and control plants was -2.0 and -5.5 MPa, respectively, 28 days after treatment. The relative water content of leaves of treated plants was 45% greater than controls. The average loss of water via transpiration of treated plants was 32% less than the control plants.

Experiments were carried out for 3 years on `Gala' and `Fuji' apple cultivars. The efficacy of the compounds applied during blooming (ATS, Armothin) and at 10 mm king fruit diameter (BA, CPPU, and NAA) was studied. Results showed a poor efficacy of the chemicals applied during bloom, while compounds applied at fruit set showed interesting results. Among the new chemicals, citokinins were the most effective, although their effects were related to the cultivar: BA performs better than CPPU on `Fuji' while vice versa on `Gala'. In addition, both chemicals induced a slightly higher °Brix content, and acidity level showed the tendency to increase L/D ratio of the fruits as compared to controls. Fruit thinning and the strategies to enhance fruit size are applied early in the season and the problem remains, to assess their effectiveness as early as possible in order to adapt the management techniques (e.g., further thinning, if applicable, or fine-tuning of nutrition and irrigation, etc.) to enable the fruit to reach their maximum potential development. A modelling approach proposed by Lakso et al. (1995) postulates that apples grow in weight according to an equation termed “expolinear” (Goudriaan and Monteith, 1990) because after an initial phase of exponential growth (cell division), the apple enters a phase of linear growth (cell expansion) lasting up to harvest. The effectiveness of a thinning agent can therefore be evaluated-and explained-in terms either of the number of cells of the cortex tissue, or of their volume, or both. In addition, assessing the slope of the linear phase as early as possible might provide a prediction tool to evaluate size at harvest. This paper presents data from apple thinning trials on several cultivars. The effectiveness of these applications has been evaluated via an analysis of the cell parameters (number, volume and intercellular spaces) of the fruit's parenchyma cortex tissue. Also, fruit growth data have been used to test the possibility to predict fruit size at harvest once the fruit reaches the phase of linear growth.

Introduction. The low solubility of active pharmaceutical ingredients (APIs) in the physiological pH range of the intestinal tract can adversely affect their absorption and bioavailability. Various methods of increasing the solubility of APIs have been proposed in recent decades. Among them there are preparation of solid dispersions, micronization, solubilization and other methods, including ones based on the amorphization of the crystalline substances, such as, spray drying, hot melt extrusion, absorption on mesoporous carriers such as magnesium aluminosilicate, silica, etc.Aim. Study the technological methods effect on dissolution at physiological temperature and pH range of practically insoluble API efavirenz amorphized by absorption on mesoporous carriers.Materials and methods. Efavirenz form І (EFA) (LLC "AMEDART", Russia, batch 010520). Efavirenz reference standard (USP № R09740). Mesoporous carriers (MC): Silica – Syloid® 244FP (244), Syloid® XDP 3150 (3150) (W.R. Grace&Co.-Conn, USA); FujiSil™ (FSL) (Fuji Chemical Industries Co., Ltd., Japan); Aeroperl® 300 (APL) (Evonik, Germany); Parteck® SLC (SLC) (Merck Millipore, USA); Synthetic magnesium aluminometasilicate – Neusilin® US2 (US2), Neusilin® UFL (UFL) (Fuji Chemical Industry Co., Ltd., Japan). The API absorption on MC was performed via solvent wetting and hot melt extrusion methods.Results and discussion. The dissolution increases in the MC series as the following: SLC > FSL > UFL = US2 > 244 = 3150. The data are consistent with an increase in the surface area and a decrease in the pore size of MC. The crystalline state of the system API efavirenz-Aeroperl® is caused by the largest pore size. It is obvious according to the data that the solvent wetting method gives better results in comparison with the hot melt extrusion as the method of obtaining X-ray amorphous systems API efavirenz-MC.Conclusion. Solvent wetting technology is recommended for increasing the dissolution of practically insoluble APIs. The preferable mesoporous carriers are silica Parteck® SLC or synthetic magnesium aluminometasilicate Neusilin® US2.

Trans-ferulic acid-4-β-glucoside (C16H20O9, TFA-4β-G) is a monomer extracted from the Chinese medicine called radix aconiti carmichaeli (Fuzi). To date, research on this substance is lacking. Here, we found that trans-ferulic acid-4-β-glucoside effectively promoted cold acclimatization in mice via increased heat production and alleviation of oxidative stress in a cold environment. Thus, our work indicates that ferulic acid-4-β-glucoside is a potential therapeutic candidate for prevention and treatment of cold stress injury.

To investigate the toxicity of water and ethanol “Fuzi” (FZ) extracts and to explore the toxicity mechanism in rats. Water and ethanol extracts were prepared. Three groups of rats received the water extract, ethanol extract, or water by oral gavage for seven days. Pathological section staining of heart tissue. Colorimetric analysis was used to determine serum lactate dehydrogenase. The metabolic expression of small molecules in rats was measured by a metabolomics method. Western blotting was used to detect the expression of phosphoinositide 3-kinase (PI3K), protein kinase B (Akt), mammalian target of rapamycin (mTOR), transforming growth factor-β1 (TGF-β1), and caspase-3. Immunohistochemistry was used to detect the expression of CTnI, mTOR, and TGF-β1. The water and ethanol FZ extracts exert cardiotoxic effects via activating the PI3K/Akt/mTOR signaling pathway to induce cardiomyocyte apoptosis.

Fuzi (Aconitum carmichaelii Debx) has been traditionally used for the treatment of ulcerative colitis (UC) in China for thousands of years. The total alkaloids of A. carmichaelii (AAC) have been considered as the main medicinal components of fuzi, whereas its underlying anti-UC mechanisms remain elusive. In the present study, the dextran sulfate sodium (DSS)-induced UC mice model, which was consistent with the symptoms and pathological features of human UC, was established to comprehensively evaluate the anti-UC effects of AAC. The results indicated that AAC effectively improved the weight loss, disease activity index (DAI), spleen hyperplasia, and colon shortening, and thus alleviated the symptoms of UC mice. Meanwhile, AAC not only inhibited the MPO enzyme and the abnormal secretion of inflammatory cytokines (TNF-α, IL-1β, IL-6, IFN-γ, and IL-17A) and suppressed the overexpression of inflammatory mediators (TNF-α, IL-1β, and IL-6) of mRNA but also reduced the phosphorylation of p38 MAPK, ERK, and JNK, and the protein expressions of NF-κB, IκB-α, STAT3, and JAK2 in the colon tissue. Furthermore, the LC-MS/MS quantitative determination suggested that the three low toxic monoester alkaloids were higher in both contents and proportion than that of the three high toxic diester alkaloids. Additionally, molecular docking was hired to investigate the interactions between alkaloid-receptor complexes, and it suggested the three monoester alkaloids exhibited higher binding affinities with the key target proteins of MAPK, NF-κB, and STAT3. Our finding showcased the noteworthy anti-UC effects of AAC based on the MAPK/NF-κB/STAT3 signaling pathway, which would provide practical and edge-cutting background information for the development and utilization of A. carmichaelii as a potential natural anti-UC remedy.

Singlet fission (SF) is expected to exceed the Shockley–Queisser theoretical limit of efficiency of organic solar cells. Spin-entanglement in the triplet pair state via one singlet exciton is a promising phenomenon for several energy conversion applications including quantum information science. However, direct observation of the electron spin polarization by transports of entangled spin-states has not been demonstrated. Furthermore, vibronic mechanisms of the dissociation of the triplet excitons are poorly understood. In this study, time-resolved electron paramagnetic resonance has been utilized to observe the transportations of the singlet and quintet characters generating spin-correlated correlated triplet pair (SCTP) by probing the electron spin polarization (ESP) generated in thin films of 6,13-bis(triisopropylsilylethynyl)pentacene.[1] We have clearly demonstrated that the ESP detected in resonance field positions of the individual triplet excitons are dependent on morphology and on detection delay time after laser flash to cause SF. The ESPs were clearly explained by quantum superposition[1,2,3] of singlet-triplet-quintet wavefunctions via picosecond triplet-exciton dissociation as the electron spin polarization transfer from strongly exchange-coupled singlet TT states to the weakly-coupled SCTP via spin-spin dipolar couplings with preserving conformations of the excitons. Although the coherent superposition of the spin eigenstates was not directly detected, the present interpretation of the spin correlation of the separated T+T exciton pair may pave new avenues not only for elucidating the vibronic role on the de-coupling[2,3] between the two excitons but also for scalable quantum information processing using quick T+T dissociation via one-photon excitation.
