Published: January 2021

Objectives: This study aimed to evaluate the fracture resistance of over flared endodontically treated bovine central incisors restored with prefabricated and custom-made glass fiber posts, using the multi-post approach.
Materials and Methods: Sixty-eight crownless over flared endodontically treated incisors were used for this study. The depth of prepared post space was 10 mm, and the remaining dentin thickness of the roots was 1 mm. The samples were randomly divided into four groups (n=17): Group 1: two prefabricated glass fiber posts; group 2: prefabricated glass fiber post + braided glass fiber; group 3: braided glass fiber; group 4: no post. Static load was applied at a crosshead speed of 0.5 mm/min at 135º angle relative to the root longitudinal axis until fracture. The data were analyzed using one-way ANOVA and post hoc Tukey’s test at a significance level of P<0.05.
Results: Groups 3 and 4 exhibited the maximum (981 N) and minimum (461 N) fracture strength values, respectively. The differences between group 4 and other groups were significant (P<0.001), but the differences between groups 1, 2, and 3 were not significant (P>0.05).
Conclusion: Multiple prefabricated and custom-made glass fiber posts significantly increased the fracture resistance of crownless endodontically treated central incisors with over flared root canals.

Authors: Saeed Amna , Rehman Aiman 
Published: January 2021

Purpose of the study: The present study aims to analyze the text This House of Clay and Water (2017) by Mansab, through the Existentialist Feminist lens in the light of Simone de Beauvoir’s theory as explained in her revolutionary work, The Second Sex (2009). The purpose of the study is not only to highlight women’s oppression/ othering in marriage due to patriarchy but also to mark the role of the ‘husband’ as crucial to the understanding of women’s emotional abandonment in marriage.
Methodology: The study is qualitative and uses a descriptive analysis of the selected text. The method of literary analysis used in the text is based on a close reading of the narrative description and events of alienation of the identity persona of the protagonist in the text.
Main Findings: The present study draws on Simone de Beauvoir’s ideas about how women are treated as others by the male subject in marriage resulting in a feeling of frustration, identity loss alienation, and existential crisis. Moreover, the role of the husband is crucial to avoid this crisis in women after marriage.
Application of the study: This study can have many applications in various fields. The study demonstrates the impacts of social and cultural stereotypes on women as well as the role of patriarchy and resulting alienation. This study can have many applications in gender and feminist studies. This study can also be helpful in the academic setting for research purposes especially in feminism, gender studies, and female existentialism.
The novelty of the study: The present study demonstrates how the protagonist feels entrapped and suffocated in her home, forced to live a life of false hope due to the impositions placed on her by her parents, her husband, her in-laws, and the patriarchal society which resultantly creates a feeling of alienation. The study concludes how dissuading a woman from her true self and forcing her to exist as an object results in a feeling of dissatisfaction, existential crisis, and alienation. The selected text has not been explored through the lens of Existential Feminism before.

Abstract
Radical polymerization of methylmethacrylate in an aqueous emulsion was carried out using the complex oxide RbTe 1.5 W 0.5 O 6 as a photoinitiator under visible light irradiation with λ= 400-700 nm. Studies of the process and reaction products using modern methods of physical and chemical analysis (GPC, IR, NMR, etc.) have shown that several directions of monomer transformations occur simultaneously in the reaction mixture. Polymethylmethacrylate, produced in the organic phase and characterized by Mn ~ 140-145 kDa, is a result of polymerization initiation by a hydroxyl radical formed due to complex transformations of electron-hole pairs during irradiation of the photocatalyst. Moreover, the interaction of the hydroxyl radical with OH groups on the complex oxide RbTe 1.5 W 0.5 O 6 surface and the subsequent formation of oxygen-centered radicals lead to grafting polymer macromolecules onto the photocatalyst surface. In addition, methylmethacrylate is able to oxidize to a cyclic dimer with terminal double bonds and then form a polymer with cyclic dimer links due to coordination by double bonds on the complex oxide RbTe 1.5 W 0.5 O 6 surface. The high activity of the hydroxyl radical made it possible to obtain the graft copolymer PMMA-pectin by grafting the polymer product onto the surface of the natural polymer-pectin. Comparison of the sponge morphology of the graft copolymer PMMA-pectin and the initial pectin samples using the scanning electron microscopy method showed a noticeable difference in their structural and topological organization. This fact is especially interesting in terms of studying the properties of the graft copolymer as a material for the scaffolds.
Paleo-earthquake Evidence and Earthquake Recurrence for Düzce Fault, Turkey
Authors: Komut Tolga , Karabudak Ersin 
Published: January 2021

Abstract
Paleoseismological trenching was performed along the Düzce fault providing some preliminary insight about its seismogenic behavior. Dating was based on radiocarbon analysis of peat samples collected from the trenches and suggested seven earthquakes have occurred since 1740 BC. Integrating date constraints of events exposed in the trenches suggests a periodical earthquake recurrence model. According to a linear sequential event serial that has minimum misfit determined by considering the probability curve limits of the sample dates, the earthquake recurrence interval is between 384 and 460 years (or possibly between AD 394 and 400). A probability curve was also calculated for the date of the last earthquake (1999 Düzce earthquake) considering the probability distributions of sample dates based on the same event serial. This probability-distribution-based method, similarly, predicted that the 1999 Düzce earthquake occurred between 1933–2005 (± 36 years) with a 68 % probability. After this verification. Using this method, it was estimated that the next earthquake along the Düzce fault has a 68 % probability of occurring between 2328–2392. According to this calculation, the earthquake recurrence interval is about 391 ± 34 years with a 68 % probability and the AD 967 historical earthquake likely ruptured the Düzce fault. Assuming an average slip of 350 cm (the average slip of the 1999 earthquake), the slip rate was estimated to be between 8.7–11.2 mm/a.

Abstract
BackgroundGlioblastoma (GBM) is a tumor of the central nervous system carries an extremely poor prognosis. Unfortunately, it also is the most frequently encountered tumor in this region. These tumors arise from glioblastoma stem cells (GSCs), which are glioma cells that are known to possess high degrees of stemness. GBM invades through the process of EMT, which features loss of cell differentiation and polarity. Survivin is a type of apoptotic inhibitor that has been characterized in several malignancies such as glioma. Normal tissues rarely express survivin. On the other hand, 3-benzyl-5-((2-nitrophenoxy) methyl) dihydrofuran-2(3H)-one (3BDO) represents an autophagy inhibitor and activates the mTOR pathway. It has been reported that 3BDO shows anti-cancer activities in lung carcinoma. However, the effects of 3BDO on GBM reminds unknown. Therefore, the purpose of this study was to explore the role and molecular mechanisms that 3BDO mediates in GBM.MethodCCK-8 experiments and clone formation assay were performed to detect the cell proliferation. Transwell assay was conducted to examined cell migration and invasion. Western blotting and immunofluorescence staining was used to analyze protein expression levels. Xenograft mouse model was used to evaluate the effect of 3BDO in vivo.ResultsWe found that 3BDO inhibited U87 and U251 cell proliferation in a dose-dependent manner. Additonally, 3BDO decreased the sphere formation and stemness markers (sox2, nestin and CD133) in GSCs. 3BDO also inhibited migration, invasion and suppressed EMT markers (N-cadherin, vimentin and snail) in GBM cells. Moreover, we found that 3BDO downregulated survivin expression of survivin both in GBM cells (U87, U251) and GSCs. Furthermore, overexpression of survivin reduced the therapeutic effects of 3BDO on GBM cell EMT, invasion, migration and proliferation, as well as decreased stemness in GSCs. Finally, we demonstrated that 3BDO inhibited tumor growth in a tumor xenograft mouse model constructed using U87 cells. Similar to the in vitro findings, 3BDO diminished suvivin expression, stemness and levels of EMT makers in vivo.Conclusionsour results demonstrated that 3BDO repressed GBM via downregulating survivin-mediated stemness and EMT both in vitro and in vivo.
Estimating the Incidence of Conjunctivitis by Comparing the Frequency of Google Search Terms With Clinical Data: Retrospective Study
Authors: Kammrath Betancor Paola , Tizek Linda , Zink Alexander , Reinhard Thomas , Böhringer Daniel 
Published: January 2021

Background
Infectious conjunctivitis is contagious and may lead to an outbreak. Prevention systems can help to avoid an outbreak.

Objective
We aimed to evaluate if Google search data on conjunctivitis and associated terms can be used to estimate the incidence and if the data can provide an estimation for outbreaks.

Methods
We obtained Google search data over 4 years for the German term for conjunctivitis (“Bindehautentzündung”) and 714 associated terms in 12 selected German cities and Germany as a whole using the Google AdWords Keyword Planner. The search volume from Freiburg was correlated with clinical data from the Freiburg emergency practice (Eye Center University of Freiburg).

Results
The search volume for the German term for conjunctivitis in Germany as a whole and in the 12 German cities showed a highly uniform seasonal pattern. Cross-correlation between the temporal search frequencies in Germany as a whole and the 12 selected cities was high without any lag. Cross-correlation of the search volume in Freiburg with the frequency of conjunctivitis (International Statistical Classification of Diseases and Related Health Problems [ICD] code group “H10.-”) from the centralized ophthalmologic emergency practice in Freiburg revealed a considerable temporal association, with the emergency practice lagging behind the frequency. Additionally, Pearson correlation between the count of patients per month and the count of searches per month in Freiburg was statistically significant (P=.04).

Conclusions
We observed a close correlation between the Google search volume for the signs and symptoms of conjunctivitis and the frequency of patients with a congruent diagnosis in the Freiburg region. Regional deviations from the nationwide average search volume may therefore indicate a regional outbreak of infectious conjunctivitis.
A Novel Remote Follow-Up Tool Based on an Instant Messaging/Social Media App for the Management of Patients With Low Anterior Resection Syndrome: Pilot Prospective Self-Control Study
Authors: Liu Fan , Guo Peng , Su Xiangqian , Cui Ming , Jiang Jianlong , Wang Suo , Yu Zhouman , Zhou Runhe , Ye Yingjiang 
Published: January 2021

Background
Low anterior resection syndrome (LARS) is a common functional disorder that develops after patients with rectal cancer undergo anal preservation surgery. Common approaches to assess the symptoms of patients with LARS are often complex and time-consuming. Instant messaging/social media has great application potential in LARS follow-up, but has been underdeveloped.

Objective
The aim of this study was to compare data between a novel instant messaging/social media follow-up system and a telephone interview in patients with LARS and to analyze the consistency of the instant messaging/social media platform.

Methods
Patients with R0 resectable rectal cancer who accepted several defecation function visits via the instant messaging/social media platform and agreed to a telephone interview after the operation using the same questionnaire including subjective questions and LARS scores were included. Differences between the 2 methods were analyzed in pairs and the diagnostic consistency of instant messaging/social media was calculated based on telephone interview results.

Results
In total, 21 questionnaires from 15 patients were included. The positive rates of defecation dissatisfaction, life restriction, and medication use were 10/21 (48%), 11/21 (52%), and 8/21 (38%) for telephone interview and 10/21 (48%), 13/21 (62%), and 5/21 (24%) for instant messaging/social media, respectively. No statistically significant difference was observed between instant messaging/social media and telephone interview in terms of total LARS score (mean 22.4 [SD 11.9] vs mean 24.7 [SD 10.7], P<.21) and LARS categories (Z=–0.264, P=.79); however, instant messaging/social media showed a more negative tendency. The kappa values of 3 subjective questions were 0.618, 0.430, and 0.674, respectively. The total LARS scores were consistent between both groups (Pearson coefficient 0.760, P<.001; category correlation coefficient 0.570, P=.005). Patients with major LARS had highly consistent results, with sensitivity, specificity, kappa value, and P value of 77.8%, 91.7%, 0.704, and .001, respectively.

Conclusions
Instant messaging/social media can be a major LARS screening method. However, further research on information accuracy and user acceptance is needed before implementing a mature system.
