Published: November 2021

Background
Along with the growing geriatric population, the number of odontoid fractures is steadily increasing. However, the effectiveness of immobilizing geriatric odontoid fractures using a cervical collar has been questioned. The aim of the present study is to analyze the physiological and pathological motion in odontoid fractures and to assess limitation of motion in the cervical spine when applying a cervical collar.

Methods
Motion analysis was performed with wireless motion tracker on unfixed geriatric human cadavers. First, a new geriatric type II odontoid fracture model was developed. In this model, the type II odontoid fracture is operated via a transoral approach. The physiological and pathological flexion and lateral bending of the cervical spine resulting from this procedure was measured. The resulting motion after external stabilization using a cervical collar was analyzed.

Results
The new geriatric type II odontoid fracture model was successfully established using seven unfixed human cadavers. The pathological flexion of the cervical spine was significantly increased compared to the physiological flexion (p = 0.027). Furthermore, the flexion was significantly reduced when a cervical collar was applied. In case of flexion the mean remaining motion was significantly reduced (p = 0.0017) from 41° to 14°. For lateral bending the mean remaining motion was significantly reduced (p = 0.0137) from 48° to 18°.

Conclusions
In case of type II odontoid fracture, flexion and lateral bending of the cervical spine are increased due to spinal instability. Thus, if an odontoid fracture is suspected in geriatric patients, the application of a cervical collar should always be considered since external stabilization can significantly reduce flexion and lateral bending.

Published: November 2021

Background
Oral microbiome transplantation (OMT) is a novel concept of introducing health-associated oral microbiota into the oral cavity of a diseased patient. The premise is to reverse the state of oral dysbiosis, and restore the ecological balance to maintain a stable homeostasis with the host immune system. This study will assess the effectiveness, feasibility, and safety of OMT using an interdisciplinary approach.

Methods/Design
To find donors suitable for microbial transplantation, supragingival plaque samples will be collected from 600 healthy participants. Each sample (200μL) will subsequently be examined in two ways: 1) 100μL of the sample will undergo high-throughput 16S rRNA gene amplicon sequencing and shotgun sequencing to identify the composition and characterisation of a healthy supragingival microbiome, 2) the remaining 100μL of the plaque sample will be mixed with 25% artificial saliva medium and inoculated into a specialised in-vitro flow cell model containing a hydroxyapatite disk. To obtain sufficient donor plaque, the samples would be grown for 14 days and further analysed microscopically and sequenced to examine and confirm the growth and survival of the microbiota. Samples with the healthiest microbiota would then be incorporated in a hydrogel delivery vehicle to enable transplantation of the donor oral microbiota. The third step would be to test the effectiveness of OMT in caries and periodontitis animal models for efficacy and safety for the treatment of oral diseases.

Discussion
If OMTs are found to be successful, it can form a new treatment method for common oral diseases such as dental caries and periodontitis. OMTs may have the potential to modulate the oral microbiota and shift the ecological imbalances to a healthier state.

Published: November 2021

Background
Thousands of people worldwide are suffering the consequences of coronavirus disease-2019 (COVID-19), and impulse oscillometry (IOS) and lung ultrasound (LUS) might be important tools for the follow-up of this population. Our objective was to prospectively evaluate abnormalities detected using these two methods in a cohort of COVID-19 survivors with respiratory symptoms.

Methods
In this follow-up study, 59 patients underwent clinical evaluations, spirometry, IOS and LUS in the 2nd (M1) and 5th (M2) months after diagnostic confirmation of COVID-19 by real-time reverse transcriptase–polymerase chain reaction. Aeration scores were obtained from the LUS exams based on the following findings: B-lines >2, coalescent B-lines, and subpleural consolidations.

Results
Fifty-nine (100%) participants had cough and/or dyspnea at M1, which decreased to 38 (64.4%) at M2 (p = 0.0001). Spirometry was abnormal in 26 (44.1%) and 20 (33.9%) participants at M1 and M2, respectively, although without statistical significance (p = 0.10). Normal examination, restrictive patterns, and obstructive patterns were observed in 33 (55.9%), 18 (30.5%), and 8 (13.6%) participants, respectively, at M1 and in 39 (66.1%), 13 (22%), and 7 (11.9%) participants at M2 (p = 0.14). Regarding IOS, considering changes in resistive and reactive parameters, abnormal exams were detected in 52 (88.1%) and 42 (71.2%) participants at M1 and M2, respectively (p = 0.002). Heterogeneity of resistance between 4 and 20 Hz >20% was observed in 38 (64.4%) and 33 (55.9%) participants at M1 and M2, respectively (p = 0.30). Abnormal LUS was observed in 46 (78%) and 36 (61%) participants at M1 and M2, respectively (p = 0.002), with a reduction in aeration scores between M1 and M2 [5 (2–8) vs. 3 (0–6) points, p<0.0001].

Conclusions
IOS and LUS abnormalities are frequent in the first 5 months post-COVID-19 infection; however, when prospectively evaluated, significant improvement is evident in the parameters measured by these two methods.

The New Inscription from Türkmenkarahöyük and its Historical Context
Authors: Hawkins J. David , Weeden Mark 
Published: November 2021

AbstractThe publication of a hieroglyphic inscription found at Türkmenkarahöyük in the Konya region and the associated survey-work in the area have raised numerous questions about the location of the city of Tarhuntassa, the aftermath of the Hittite Empire and the dating of the Hieroglyphic inscriptions which mention a king called Hartapu. In this paper we review the evidence for the location of Tarhuntassa that we deem relevant for deciding whether it could have been situated at Türkmenkarahöyük, and further reconsider the dating of the Hartapu inscriptions, arriving at the conclusion, already warranted by the evidence before the discovery of the new inscription, that there must have been two kings called Hartapu, who lived in very different epochs.
Duty to Read vs Duty to Disclose Fine Print. Does the Market Structure Matter?
Authors: D’Agostino Elena , De Benedetto Marco Alberto , Sobbrio Giuseppe 
Published: November 2021

AbstractFirms use standard contracts and possibly include unfavorable fine print which consumers may read at some positive cost. We propose a comparison between a monopoly and a perfect competition market under (1) an unregulated legal regime (duty to read) and (2) a regulation that mandates clause disclosure (duty to disclose). If consumers bear the duty to read contract terms, regardless of market structure, sellers disclose in equilibrium only if it is cheaper than reading for consumers. Conversely, if sellers bear the duty to disclose contract terms, then such regulation is never welfare improving in either market; it may turn out to be consumer protective only if there are several sellers, whereas it is uneffective on this regard in a monopoly.
The Transgender Imagination in Folk Narratives: The Case of ATU 514, “The Shift of Sex”
Authors: Ready Psyche Z. 
Published: November 2021

Abstract
“The Shift of Sex” is a folktale type that begins with a young woman dressing in men’s clothes to have an adventure, and ends when the protagonist is magically transformed into a man, marries a woman, and lives happily ever after. My goal in this project is to analyze the 26 variants as a group in order to illuminate what they communicate about gender and transgender. ATU 514 has been treated as an aberration or anomaly, a tale that defies categorization. Several feminist scholars have argued that the climactic change of gender reinforces heteronormativity and sexist, patriarchal gender roles. More recent scholarship notes the tale’s transgender possibility, scholarship I build on in this project. My analysis identified two significant patterns in the tales: first, every variant has a happy ending for the protagonist, representing a narrative reward for a character who could variously be read as transgender or gender transgressive. Second, the tales are encoded with details, characters, and events that tell a “secondary narrative” that describes the threat of the patriarchy. I argue that the protagonist of ATU 514 is a transgressive character with transgender capacity and that the tale approves and rewards these transgressions through the concluding happily-ever-after.
Establishing a Sprachbund in the Western Lingnan region: conceptual and methodological issues
Authors: Szeto Pui Yiu , Yurayong Chingduang 
Published: November 2021

AbstractIt is well-known that Tai-Kadai languages have affected the typological profiles of Southern Sinitic varieties. For example, compared with their northern sisters, Southern Sinitic varieties display a stronger tendency towards head-initial structures, as in theN–Ncompounds for expressing the sex of animals and in post-verbal temporal adverbs. Given that the Tai-Kadai languages in China have been in contact with Sinitic for over two millennia, it is quite natural to find signs of Sinitic influence therein. Most remarkably, pre-verbal adjunct phrases and pre-nominal relative clauses, which are extremely atypical ofVOlanguages but distinctive of Sinitic, are attested in some Tai-Kadai languages in Southern China. The prevalence of such typologically unusual traits among different linguistic groups in the Lingnan region of Southern China provides strong support for its status as a linguistic area. Devising and adopting a ‘mutualist’ approach, we analyse the typological data of over 280 language varieties, which we believe illustrates and strongly supports the idea that Western Lingnan qualifies as a linguistic area in its own right according to criteria widely recognized by areal linguists. The approach proposed in this study can be applied to other putative linguistic areas around the world to study the mechanisms and outcomes of contact-induced change under a specific set of ecological conditions.
Valuation of the American put option as a free boundary problem through a high-order difference scheme
Authors: Sari Murat , Gulen Seda 
Published: November 2021

Abstract
Valuation of the American options encountered commonly in finance is quite difficult due to the possibility of early exercise alternatives. Since an exact solution for the American options does not exist, effective numerical methods are needed to understand the behavior of option pricing models. Therefore, in this paper, a new approach based on a high-order difference scheme is proposed to discuss the valuation of an American put option as a free boundary problem. Using a front-fixing approach that transforms the unknown free boundary (optimal stopping) into a fixed one, a sixth-order finite difference scheme (FD6) in space and a third-order strong-stability preserving Runge–Kutta (SSPRK3) in time are applied to the model converted to a nonlinear partial differential equation. The computed results revealed that the combined method is seen to attempt to pull up the capacity of the algorithm to achieve higher accuracy. It is seen that the quantitative and qualitative results produced by the method proposed with minimal computational effort are sufficiently accurate and meaningful. Therefore, this article provides some new insights about the physical characteristics of financial problems and such realistic phenomena.

Published: November 2021

Abstract
Bats spend more than half of their life in roosts, where key life events transpire. Therefore the availability and selection of roosts are important to bats everywhere, and may limit their ability to exploit every habitat, including agricultural landscapes such as paddy fields, orchards and tea plantations. This study aimed to investigate the day roosts used by insectivorous bat species in tea plantations of Sri Lanka. We surveyed 18 tea plantations where we recorded a total of 44 roosts involving five families and nine species of bats (Hipposideros galeritus, Hipposideros lankadiva, Hipposideros speoris, Rhinolophus beddomei, Rhinolophus rouxii, Megaderma spasma, Pipistrellus ceylonicus, Pipistrellus coromandra and Miniopterus cf. fuliginosus). Most (26) of the recorded roosts were geomorphic, (11) were anthropogenic, and (7) were in vegetation. H. lankadiva and M. cf. fuliginosus are the only species known to roost exclusively in geomorphic roosts; all others were opportunistic. Although protecting bat roosts is crucial for their conservation, it is challenging in view of existing tea management practices. Therefore, natural roosts should be maintained and protected. The introduction of artificial roosts might increase the number of bats able to forage over tea plantations and maximize their consumption of agricultural pests, thereby increasing tea production.
Tunable Faraday rotation of ferromagnet thin film in whole visible region coupled with aluminum plasmonic arrays

Published: November 2021

Abstract
To date, the plasmonic nanostructure utilized for magneto-optical (MO) enhancement has been limited to noble metals with resulted enhancement in the green-red part of visible spectrum. In this study, we fabricated a diffractive hexagonal array composed of Al nanoparticles (NPs) with a thin 7.5 nm ferromagnetic film and pushed the enhanced Faraday rotation (FR) into the blue to green range of the visible light. The freedom and ability to control the working spectral region in the whole visible range from 400 to 800 nm were also demonstrated by changing the lattice constant and the dielectric environment of plasmonic nanostructures. Particularly, in the blue range we obtained the maximum FR 0.57° at 410 nm with a broad boosting region around 0.5° from 400 to 500 nm. Moreover, the largest FR 1.66° was shown at 638 nm by tuning the dielectric environment into a higher refractive index medium. The results of our investigation demonstrate the potential of Al-based magnetoplasmonic effect and offer opportunities to push the MO spectral response out of visible range into the ultraviolet-blue range.
Investigating Disinformation in Middle East Mainstream News – Operationalization, Detection, and Implication
Authors: Barkho Leon 
Published: November 2021

AbstractThis paper develops some discursive resources and models to analyze how and why disinformation permeates mainstream media. It draws on certain linguistic strategies and propaganda models helpful to unravel disinformation in mainstream media coverage, with focus placed on two main Arabic speaking 24/7 news channels in the Middle East. These strategies and models are used to conduct exploratory critical analyses of data drawn from the online news websites of the two news outlets. The paper presents the trends characterizing disinformation in the Middle East, but more importantly the discursive and social patterns and practices the media employ when publishing news intended to discredit and harm rather than inform. The study’s contribution is twofold: First, it provides a discursive framework for the analysis of disinformation in traditional news outlets. Second, it provides an analytical framework to investigate how disinformation pervades mainstream media. The study’s data and analysis support the lines of research on how patriotic ethics guide coverage and how the selection of discursive patterns responds to interests of hegemonic powers with a say in media organizations’ affairs.
Synthesis of “(aminomethyl)phosphonic acid-functionalized graphene oxide”, and comparison of its adsorption properties for thorium(IV) ion, with plain graphene oxide

Published: November 2021

Abstract
The current study presents a simple and scalable method for the synthesis of (aminomethyl)phosphonic acid-functionalized graphene oxide (AMPA-GO) adsorbent. The chemical structure of the new material was disclosed by different instrumental analyses (e.g. FTIR, Raman, XPS, AFM, TEM, XRD, CHN, and UV), and two pertinent mechanisms namely nucleophilic substitution and condensation were suggested for its formation. Adsorption experiments revealed that both AMPA-GO and plain GO have a high affinity toward Th(IV) ions, but the AMPA-GO is superior in terms of adsorption capacity, rate of adsorption, selectivity, pH effect, etc. Indeed, the AMPA-GO can uptake Th(IV) nearly instantaneously, and coexisting Na+ ions have no effect on its adsorption. Thanks to Langmuir isotherm, the maximum adsorption capacities of the GO and AMPA-GO were obtained 151.06 and 178.67 mg g−1, respectively. Interestingly, GO and AMPA-GO both showed a higher preference for thorium over uranium so that the average “K

d
(Th)/K

d
(U)” for them was 52 and 44, respectively. This data suggests that chromatographic separation of thorium and uranium is feasible by these adsorbents.
The evaluation of PIK3CA gene variation and serum PI3K level in breast cancer risk and prognosis in Turkish population
Authors: Ulu Elif , Yaylım İlhan , Arıkan Soykan , Cacına Canan 
Published: November 2021

Abstract

Objectives
The PI3K (Phosphatidylinositol 3-kinase) is the member of lipid kinase family that plays important roles in tumorigenesis, cancer development and cell proliferation. In our study, we aimed to investigate the relationships between breast cancer risk and prognosis with PIK3CA rs6443624 (C>A) intron region gene polymorphism and serum PI3K levels.

Methods
A total of 61-patients with breast cancer and 101 controls were included to the study. PIK3CA polymorphism was detected by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) technique. Serum PI3K levels were measured by Enzyme-Linked Immuno Sorbent Assay (ELISA).

Results

PIK3CA (C>A) gene polymorphism genotype and allele distributions were no significant in cases and controls (p>0.05). The serum PI3K levels of breast cancer patients were found significantly higher than the control groups (p=0.033). There were not significant association between PIK3CA (C>A) gene polymorphism and clinic and prognostic parameters in our study group. We also evaluated serum PI3K levels in the term of tumor progression, but we did not observe any significant data.

Conclusions
We suggest that serum PI3K levels may play role in breast cancer risk and larger patient groups may have clinical value in assessment of the genetic risk and tumor progression of breast cancer.

Abstract
Burke, J, Geller, JS, Perez, JR, Naik, K, Vidal, AF, Baraga, MG, and Kaplan, LD. The effect of passing plays on injury rates in the national football league. J Strength Cond Res 35(12S): S1–S4, 2021—The National Football League (NFL) has one of the highest all-cause injury rates in sports, yet our understanding of extrinsic injury risk factors is limited. The objective of this study was to assess the effect of play type on injury incidence in the NFL. We obtained data for every regular season game played during the 2013–2016 seasons from the official NFL game books. There were 2,721 in-game injuries during the 4 seasons examined, with an overall rate of 1.33 injuries per team per game. For statistical analysis, p < 0.05 was considered significant. Passing plays conferred significantly higher odds of injury than running plays (odds ratio [OR] 1.4, 95% confidence interval [CI]: 1.3–1.5, p < 0.0001). This primarily stems from increased risks in quarterbacks (OR 6.9, 95% CI: 3.6–13.3, p < 0.0001), receivers (OR 5.0, 95% CI: 3.7–6.6, p < 0.0001), and defensive backs (OR 2.3, 95% CI: 1.9–2.7, p < 0.0001). Our study suggests that passing plays confer a greater risk of overall injuries in the NFL when compared with running plays, specifically regarding concussions and core or trunk injuries.
