ABSTRACTIntroduction and aimPremature exfoliation or extraction of primary tooth may lead to loss of space due to drifting of the adjacent teeth. This may also lead to undesirable effects, such as impaction of the succedaneous tooth, overeruption of the opposing tooth, and a shift of the midline, with consequent functional impairment. It is prudent to consider space maintenance when primary teeth are lost prematurely. The current study aims to clinically evaluate the effectiveness of space maintainers comparing conventional band and loop space maintainer with glass fiber-reinforced space maintainer following loss of primary teeth in mixed dentition.Materials and methodsA total of 30 children aged 4 to 8 years were randomly assigned into two groups – band-and-loop space maintainer (group I) and glass fiber-reinforced composite (GFRC) space maintainer (group II). Distortion/dislodgment of the loop or the fiber frame, fracture of loop or fiber frame, gingival health, and space loss were evaluated clinically and radiographically at 1, 3, 6, and 12 months interval. Gingival health was assessed by gingival index given by Loe and Silness.ResultsBased on the statistical analysis, overall success rate of group I was found to be 69.2% and of group II was 95.7% (p = 0.026), which was statistically significant.ConclusionThe GFRC space maintainers showed an overall success rate compared with band-and-loop space maintainers.How to cite this articleKataria S, Chunawala Y, Morawala A, Jain K, Ambiye A.

Treatment Outcome with Implant-supported Mandibular Overdenture opposing Natural Dentition
Authors: Kar Sushil , Tripathi Arvind 
Published: October 2019

ABSTRACTAlthough the conventional complete denture has been a standard treatment option for edentulous patients, it may not thoroughly fulfill the esthetic or functional needs of many denture wearers. This situation is commonly encountered, especially in relation to the mandibular ridge. Over the last decade, implant-supported overdenture has emerged as a successful alternative to the more commonly used removable prosthesis. The article discusses the fabrication procedure of an implant-assisted overdenture.How to cite this articleKar S, Tripathi A.

Outra História Global é Possível? Desocidentalizando a história da historiografia e a história antiga
Authors: Da Silva Uiran Gebara 
Published: October 2019

Este artigo traz, em sua primeira parte, uma reflexão sobre a problematização da história global como uma novidade historiográfica feita por Jurandir Malerba ao analisar seu impacto na área da história da historiografia. Ainda nessa parte, o artigo busca ressaltar a centralidade da crítica ao eurocentrismo e do impulso de desocidentalização na história global recente. Na segunda parte, com base numa comparação com os impactos da história global na História Antiga, reflito sobre os quatro pontos críticos apresentados por Malerba em suas considerações finais: o fato de objetos históricos poderem se beneficiar de uma abordagem global; a coerência narrativa e argumentativa possível aos tais objetos; os limites da expertise acadêmica para uma história global; a obsolescência prematura da história global. Na conclusão, afirma-se a singularidade da crítica desocidentalizadora na nova história global e a necessidade de os intelectuais do Sul global articularem suas histórias globais alternativas às dos intelectuais do Norte global.

IntroductionAcute liver failure (ALF) is a syndrome defined by jaundice, coagulopathy (INR > 1.5) and hepatic encephalopathy in patients with no evidence of prior liver disease. Toxins and drugs are a frequent cause of ALF in children.Material and methodsThe aim of our study was to establish the causes of toxic ALF in children followed up in our hospital in the period of January 2000 to August 2018. We retrospectively studied all hospital records of patients who developed ALF after mushroom/drug exposure and had been admitted to our hospital, the main pediatric toxicology center in north-western Romania.ResultsIn the last 18 years, 123 patients were admitted to our clinic with toxic ALF (89 patients secondary to mushroom ingestion and 34 patients after drug exposure). In the 2000-2012 period accidental mushroom poisoning was the leading cause of toxic ALF. Unfortunately, during the last years, voluntary drug ingestions have increased dramatically. The most commonly incriminated drug was acetaminophen (52.94%).ConclusionsALF in mushroom poisoning is associated with a high mortality in children, despite optimal medical therapy. This etiology was one of the most important causes of death in our cohort. The difficulty in accessing emergency liver transplantation is an obstacle common to many Eastern European pediatric centers. Fortunately, in the last 5 years the incidence of mushroom intoxications has decreased in our area. It is worrying that over the last few years there has been an increased incidence of toxic ALF after drug exposure (for suicidal purposes or due to lenient regulations for prescribing hepatotoxic medications).

IntroductionNo significant regression has been reported in revision total hip arthroplasty (THA) rates despite substantial progress in implant technologies and surgical techniques. It is critical to investigate how patient demographics, THA indications, surgical techniques, types of implants, and other factors influence the frequency of early and late revision surgery. The main purpose of the present study was to evaluate the clinical characteristics and 10-year survival rates of revision hip arthroplasties among revision time groups.Material and methodsThe clinical data of 396 patients who underwent revision hip arthroplasty between 2005 and 2011 were evaluated in this multi-centre study. Patients were assigned to one of four revision time groups based on the interval between the index hip arthroplasty and the revision surgery (< 2, 2–5, 5–10, and > 10 years).ResultsThere were significant differences among revision time groups in terms of aetiology for primary hip arthroplasty, indications for revision hip arthroplasty, and types of revision procedures. Patients with hip dysplasia more frequently received revision hip arthroplasty within two years in contrast to those with osteoarthritis. Revision hip arthroplasties due to periprosthetic infection and instability were conducted earlier compared to aseptic loosening. The overall 10-year survival rate of revision hip arthroplasty was 83.2%, and it was highest for the very early revisions (< 2 years).ConclusionsAccording to our results, early revision hip arthroplasty was found to be mostly dependent on surgery-related factors rather than demographic factors. On the other hand, we observed that survival rates of very early revision hip arthroplasties are higher than late revision hip arthroplasties.
Shyness, self-presentation, adonization, and influence tactics in close relationships
Authors: Mandal Eugenia , Wierzchoń Aleksandra 
Published: October 2019

BackgroundEmpirical research reveals the difficulties that shy people must face as part of their social functioning and at-taches a pejorative connotation to shyness in the process of establishing and maintaining interpersonal rela-tions. The purpose of the study was to investigate certain aspects of social functioning of shy people: the pre-ferred self-presentation styles, readiness to adopt adonization and influence tactics in intimate relationships.Participants and procedureThe study was performed on a group of 234 participants (113 females and 121 males), aged 18 to 35 years (M = 24.29). The following questionnaires were used: the Revised Cheek and Buss Shyness Scale, the Self-Presentation Questionnaire, the Questionnaire for Measuring the Attitude toward Adonization, and the Influence in Close Relationships between Women and Men Questionnaire.ResultsThe study found that shy people use self-promotion less frequently than non-shy persons and they tend to adopt self-depreciation more often compared to non-shy individuals. Further, a high level of shyness implies a less pronounced tendency to use adonization but a greater readiness to employ hard social influence tactics in close relationships: Threats and violence, Silent treatment and sulking and Complaining and arguing.ConclusionsCorrelations between shyness, self-presentation styles, adonization and influence tactics in close relationships emphasize the role of this disposition in generating social behaviors. Shyness has a negative impact on an individual’s social functioning and relations with other people. The negative consequences of shyness are par-ticularly conspicuous in the behavior of men.

BackgroundResearch into dieting and mindfulness has primarily focused upon how mindfulness and mindful eating affect dieting. However, the effect is bi-directional, with the process of dieting also impacting on mind-set and eating. We therefore aimed to investigate how people on different diets experience mindfulness and mindful eating. The present research aimed to explore whether or not specific weight loss diets are likely to prompt more of the elements described in mindfulness and mindful eating theory.Participants and procedureA community sample (N = 312) who were dieting at the time of recruitment were asked to fill in mindfulness and mindful eating measures, where commercial weight loss programmes (CWLP), low carbohydrate (LC), and intermittent fasting (IF) were used as dieting methods, as well as general healthy eating (GHE). Analyses of variance were conducted with the intention of comparing those groups in mindfulness and mindful eating, as well as their corresponding sub-constructs. The questionnaires and demographic information were provided through an online database, as well as other information relating to the diet, duration and history of dieting.ResultsThe results showed intermittent fasting dieters to score higher across mindfulness and mindful eating scores, although the differences from the rest of the groups were not significant. Investigating mindful eating further through the subscales revealed that CWLP scores were significantly higher in ‘routine’ when compared to GHE. Trait mindfulness subscales displayed no significant differences, except ‘describe’, which was higher in CWLP over LC dieting.ConclusionsSpecific emphasis is given to future directions, and the potential to identify diets that are theoretically and prac-tically consistent with the theory and practices of mindfulness and mindful eating.
Spatial changes in soil stable isotopic composition in response to carrion decomposition
Authors: Keenan Sarah W. , Schaeffer Sean M. , DeBruyn Jennifer M. 
Published: October 2019

Abstract. Decomposition provides a critical mechanism for returning nutrients to the
surrounding environment. In terrestrial systems, animal carcass, or carrion,
decomposition results in a cascade of biogeochemical changes. Soil microbial
communities are stimulated, resulting in transformations of carbon (C) and
nitrogen (N) sourced from the decaying carrion soft tissues, changes to soil
pH, electrical conductivity, and oxygen availability as microbial
communities release CO2 and mineralize organic N. While many of the
rapid changes to soil biogeochemistry observed during carrion decomposition
return to background or starting conditions shortly after soft tissues are
degraded, some biogeochemical parameters, particularly bulk soil stable
δ15N isotopic composition, have the potential to exhibit
prolonged perturbations, extending for several years. The goal of this study
was to evaluate the lateral and vertical changes to soil stable isotopic
composition 1 year after carrion decomposition in a forest ecosystem.
Lateral transects extending 140 cm from three decomposition “hotspots”
were sampled at 20 cm intervals, and subsurface cores were collected beneath
each hotspot to a depth of 50 cm. Bulk soil stable isotopic composition
(δ15N and δ13C) indicated that 1 year after
complete soft tissue removal and decay, soils were significantly
15N enriched by 7.5±1.0 ‰ compared to
control soils up to 60 cm from the hotspot center, and enrichment extended
to a depth of 10 cm. Hotspot soils also contained 10 % more N compared to
control soils, indicating that decomposition perturbs N pools. Our results
demonstrate that carrion decomposition has the potential to result in
long-term changes to soil biogeochemistry, up to at least 1 year after
soft tissue degradation, and to contribute to bulk soil stable isotopic
composition.
Fatty Liver Disease: A Practical Approach
Authors: Mostafa Mohamed , Abdelkader Amrou , Evans John J. , Hagen Catherine E. , Hartley Christopher P. 
Published: October 2019

Context.—
Fatty liver disease is now one of the most commonly encountered entities in the practice of liver pathology. Distinguishing simple steatosis from steatohepatitis is critical because the latter requires follow-up because of long-term risks that include cirrhosis and hepatocellular carcinoma. An organized approach for evaluating liver biopsies with steatosis is recommended to capture all of the relevant features: (1) degree of steatosis, (2) presence or absence of ballooning degeneration, (3) lobular inflammation, and (4) fibrosis. Herein, we provide a stepwise approach that readers can use to evaluate liver biopsies with steatosis, including examples, pitfalls, differential diagnostic considerations, and suggested diagnostic phrasing.

Objective.—
To provide a stepwise approach for the evaluation of liver biopsies showing significant steatosis (involving ≥5% of liver parenchyma).

Data Sources.—
Biopsies demonstrating fatty liver disease encountered in our daily practice were examined as well as recent literature.

Conclusions.—
Effective evaluation of liver biopsies with steatosis requires careful histologic examination and correlation with clinical history, particularly regarding medications, nutrition status, and alcohol use. Examples of uniform reporting, including appropriate use of the nonalcoholic steatohepatitis Clinical Research Network Activity Score, are provided.
NHC‐Catalyzed Chemoselective Reactions of Enals and Aminobenzaldehydes for Access to Chiral Dihydroquinolines
Authors: Wu Shuquan , Liu Changyi , Luo Guoyong , Jin Zhichao , Zheng Pengcheng , Chi Yonggui Robin 
Published: October 2019

AbstractAn N‐heterocyclic carbene (NHC)‐catalyzed reaction between α‐bromoenals and 2‐aminoaldehydes has been developed. Key steps include chemoselective reaction of the NHC catalyst with one of the aldehyde substrates (the bromoenal) to eventually generate an α,β‐unsaturated acylazolium intermediate. Addition of the nitrogen atom of aminoaldehyde to the unsaturated azolium ester intermediate followed by intramolecular aldol reaction, β‐lactone formation, and decarboxylation leads to chiral dihydroquinolines with high optical purity. The dihydroquinoline products, which are quickly prepared by using this method, can be readily transformed into a diverse set of functional molecules such as pyridines and chiral piperidines.

ABSTRACTThis work reports the synthesis and characterization of a series of new sulfonated copolytriazoles. The polymers were prepared by CuI catalyzed 1,3‐cycloaddition reaction of an equimolar amount of a dialkyne monomer, 1,3‐diethynylbenzene and a mixture of two diazide monomers, namely, 4,4′‐diazidodiphenyl ether and 4,4′‐diazido‐2,2′‐stilbenedisulfonic acid disodium salt. The copolymers showed high inherent viscosity indicating the formation of high molar mass product. The copolymers were characterized by Fourier transform infrared and proton nuclear magnetic resonance spectroscopic techniques. The copolymer membranes displayed moderate water uptake, high dimensional, mechanical, and thermal stability. Transmission electron microscopy micrographs displayed excellent phase‐separated morphology along with very fine ionic clusters. The copolymer PTEOSH‐90 (90% degree of sulfonation) showed much higher proton conductivity value which is up to 196 mS cm−1 at 80 °C in completely hydrated condition compared to that of Nafion (165 mS cm−1). © 2019 Wiley Periodicals, Inc.

Published: October 2019

AbstractNovel thiazolyl hydrazonothiazolamines and 1,3,4‐thiadiazinyl hydrazonothiazolamines were synthesized by a facile one‐pot multicomponent approach by the reaction of 2‐amino‐4‐methyl‐5‐acetylthiazole, thiosemicarbazide or thiocarbohydrazide and phenacyl bromides or 3‐(2‐bromoacetyl)‐2H‐chromen‐2‐ones in acetic acid with good to excellent yields. These new compounds were screened in vitro for their antimalarial activity; among them, four compounds, 4h, 4i, 4k, 4l, showed moderate activity with half‐maximal inhibitory concentration (IC50) values of 3.2, 2.7, 2.7, and 2.8 and 3.2, 3.2, 3.1, and 3.5 μM against chloroquine‐sensitive and ‐resistant strains of Plasmodium falciparum, respectively. Compound 4l inhibited the ring stage growth of P. falciparum 3D7 at an IC90 concentration of 12.5 µM in a stage‐specific assay method, where the culture is incubated with specific stages of P. falciparum for 12 hr, and no activity was found against the trophozoite and schizont stages, confirming that 4l may have potent action against the ring stage of P. falciparum.
Power quality—Evaluation of safe operation of observatories
Authors: Mann Michael , Pribulla Theodor , Döhring Thorsten , Komžík Richard , Sivanič Peter 
Published: October 2019

AbstractThe electric power supply of astronomical observatories has to manage a conflict of interest: Observatories are situated at remote locations, they have a high consumption of electric power while measuring electric signals as sensitively as possible. Within the project SLOBATCO, the question did arise, to what extent observatories have to rely on adequate power quality, for example, the perfectly sinusoidal shape of supply voltage and current, to ensure safe operation and accurate measurement results. International power quality standards are put in perspective with requirement specifications for observatories. This contribution describes the motivation, the underlying mechanisms that lead to issues, comments on the challenge in power systems engineering, proposes the instrumentation and installation, and interprets the first results. Experimental results clearly motivate the need for further measurement campaigns, as power‐quality‐related problems are common. A summary is provided together with an outlook and a motivation for future measurement campaigns.
