Effect of local injection of injectable platelet-rich fibrin on eruption rate of teeth (Rabbit animal model)
Authors: Al-Jwary Enas Talb , Al-Saleem Niam Riyadh
Published: September 2023

OBJECTIVE:

This study aimed to evaluate the effect of the local injection of injectable platelet-rich fibrin (i-PRF) on the eruption rate of the teeth and evaluation of the effect of i-PRF on the number of odontoblast, cementoblast, osteoblast, osteocyte, and osteoclast cells.

MATERIALS AND METHODS:

The samples consisted of 20 male albino rabbits and were divided randomly into the control group (5 rabbits) and i-PRF groups (15 rabbits) sub-divided into week 1, week 2, and week 3 sub-groups. The labial surface of lower right incisors was marked by drilling a hole at the level of the free gingival margin in the mid-line of each tooth with a small round bur, and the eruption rates were measured by measuring the distance from the most apical point of the free gingival margin and the center of the hole with a digital caliper. i-PRF was prepared by centrifuging autologous blood of each rabbit at 1000 rpm for 5 minutes; then the i-PRF layer was collected. The control group received no treatment, whereas i-PRF groups received i-PRF in the following manner: For week 1 groups, a single dose was given at 0 day; for week 2 groups, double doses were given at 0 and 7 days; and for week 3 groups, three doses were given at 0, 7, and 14 days. At the end of experiments for each group, animal scarification was performed, and histological steps were performed.

RESULTS:

There was a significant increase in the rate of tooth eruption in i-PRF groups when compared to the control group, and the eruption rate was increased in 107.3%, 144.7%, and 167.5% for week 1, week 2, and week 3, respectively. Concerning the histological finding, the i-PRF groups gave rise to a higher number of odontoblast, cementoblast, osteoblast, osteocyte, and osteoclast cells with a significant difference when compared to the control groups (P ≤ 0.05).

CONCLUSIONS:

Applying i-PRF significantly increased the rate of teeth eruption at all-time intervals. Platelet-rich fibrin injection can be an effective method for acceleration of teeth eruption.

Published: September 2023

OBJECTIVE:

To evaluate in-vitro surface characteristics and frictional properties of orthodontic stainless steel and beta-titanium archwires after surface modification with different concentrations and coating time of titanium oxide (TiO2) nanoparticles by Sol-gel dip coating method.

MATERIALS AND METHODS:

The experiment was carried out with 4 different concentrations (1:2, 1:4, 1:6, and 1:8) and three different dipping durations (24 hours, 48 hours, and 72 hours) over ten main test groups of SS and TMA archwires with uncoated wires acting as control in both dry and wet conditions. Phase analysis and surface characterization of TiO2 was analyzed by X-ray Diffractometry, surface evaluation with the help of scanning electron microscopy (SEM), and frictional characteristics were evaluated.

RESULTS:

Among all the concentrations 1:6 ratio with 48 hours of dipping duration showed better surface characteristics. A statistically significant difference in frictional coefficient was observed in both SS and TMA wires than their respective controls (p = 0.001). Intragroup comparison among SS and TMA groups showed that groups with 1:6 ratio and 48 hours dipping duration had least frictional coefficient in both dry and wet conditions (p = 0.001). Intergroup comparison between SS and TMA showed that SS group had significantly reduced friction than TMA (p = 0.001) except in few groups.

CONCLUSION:

TiO2 nanoparticle with a concentration ratio of 1:6 and 48 hours dipping duration is recommended for surface modification of orthodontic archwires.

AIM:

The aim of this in-vitro study was to observe and analyze the various enamel surface changes that occur due to laser debonding of metal and ceramic brackets, done by means of Er, Cr:YSGG laser.

MATERIALS AND METHODS:

90 extracted premolars were randomly allocated into one of six groups with 15 teeth each. The groups represent metal brackets (Groups A1, A2, A3) and ceramic brackets (Groups B1, B2, B3). Each sub-group represents the mode of debonding used in the study. Debonded teeth were analyzed under scanning electron microscopy (SEM) at 80X and at 1000X magnification at three sites. The adhesive remnant index (ARI) scores were analyzed and the presence of enamel damage was observed.

RESULT:

ARI showed high score in Groups A1 and B1. SEM images of large composite remnants at the site of bracket in Groups A1 and B1 at the site of bracket and multiple enamel microcracks and fractures at interface and enamel adjacent to bracket in Groups A1 and B1. SEM images of minimal composite remnants at the site of bracket in Groups A2, A3, B2, and B3 and little to no presence of enamel microcracks or fractures at interface and enamel adjacent to bracket in Groups A2, A3, B2, and B3.

CONCLUSION:

The use of Er, Cr:YSGG laser in orthodontic practice, especially in the debonding procedures of orthodontic brackets provide quality care to patient with minimal post-treatment damages.
Corneal epithelial changes in a patient treated with belantamab mafodotin
Authors: Inferrera Leandro , Giglio Rosa , Tognetto Daniele
Published: September 2023

The aim of the study is to report a case of corneal epithelial changes in a patient with refractory multiple myeloma (MM) who was treated with belantamab mafodotin (BM). A 55-year-old man diagnosed with refractory MM was referred to our hospital for treatment with BM, an antibody-drug conjugate targeting B-cell maturation antigen. After 33 days of treatment, the patient experienced a bilateral reduction in visual acuity (VA), along with dry eye symptoms such as itchy eyes and a sensation of having a foreign body. Slit-lamp examination revealed the presence of diffuse microcystic epithelial changes throughout the cornea. BM treatment was discontinued by the oncologist. Sixty days after stopping belantamab, VA gradually improved and the microcystic epithelial alterations progressively diminished. Ninety days after discontinuation of therapy, only a few microcystic epithelial alterations remained, and the patient had 20/20 VA in both eyes. While BM is an effective therapy for refractory MM, corneal epithelial changes are among the most common side effects of this treatment. Close collaboration between ophthalmologists and oncologists is crucial for assessing ocular adverse effects and tailoring treatment accordingly.

Published: September 2023

PURPOSE:

To assess the change of interleukin-6 (IL-6) levels in tears and ocular clinical parameters in corneal ulcer patients with moderate-to-severe infection after adjunctive therapy with platelet-rich fibrin (PRF) lysate-eyedrops compared with autologous serum eyedrops.

MATERIALS AND METHODS:

This study was a randomized double-blind controlled trial, which compared two groups of patients at Dr. Sardjito Hospital, Yogyakarta. A total of 42 patients (42 eyes) were divided into the control group (21 patients) and the intervention group (21 patients). All patients received antibacterial/antifungal therapy based on the etiology, and an adjunctive eyedrop therapy: autologous serum eyedrops for the control group and PRF lysate eyedrops for the intervention group. The IL-6 levels and clinical changes in patients, such as the area of corneal defects, pericorneal injection, and the level of blepharospasm were measured at the baseline, day 6, and day 13 after starting the treatment.

RESULTS:

Compared to baseline, the mean IL-6 level in day 13 decreased by 426.6 ± 665.4 pg/ml (P = 0.005) and 1283.7 ± 1569.1 pg/ml (P = 0.079) in the intervention and control groups, respectively. However, the difference between the two groups was not statistically significant (P = 0.164). In term of corneal defect area, there was a significant decrease at day 6 and day 13 in both groups but there was no statistically significant difference between the two groups in all time points. Similarly, the proportion of blepharospasm and pericorneal injection severity appeared to improve especially on day 13 in both groups but were not statistically different between the two.

CONCLUSION:

There was a statistically significant decrease in IL-6 levels in the tears in patient using PRF lysate, but there was no significant difference when compared to those using autologous serum. The difference in defect area, degree of blepharospasm, and pericorneal injection was not statistically significant between the two treatment options.
Advantages of femtosecond laser in various corneal transplantation procedures: A narrative literature review
Authors: Han Sang Beom
Published: September 2023

The ability of the femtosecond laser (FSL) to create tissue incisions at desired depth and location with minimal collateral damage to surrounding tissue may offer potential advantages for corneal transplantation surgery. FSL may enable the precise and accurate preparation of both donor and recipient tissue, which can potentially result in enhanced wound integrity, facilitation of wound healing, and improved visual outcomes. Many studies have suggested that FSL may be a viable option in various corneal transplantation procedures, such as, penetrating keratoplasty, anterior lamellar keratoplasty, endothelial keratoplasty, and novel techniques, including Bowman layer transplantation and stromal lenticule addition keratoplasty. In this review, the author presents a brief overview on the application of FSL in various corneal transplantation procedures and discusses the results of studies regarding the safety and efficacy of FSL-assisted corneal transplantation procedures.

Authors: Jurdjevic Velimir
Published: September 2023

Настоящая работа продолжает имеющее долгую историю исследование увлекательных связей алгебр и групп Ли с задачами прикладной математики. Оно берет свое начало с открытия того, что математический формализм, инициированный Г. Кирхгофом для моделирования равновесных конфигураций упругого стержня, можно распространить на группы изометрий некоторых римановых многообразий с помощью методов теории управления и принципа максимума, что приводит к большому классу гамильтоновых систем, которые по-новому связывают геометрию с физикой. Основное внимание в работе уделяется связи аффинно-квадратичной задачи типа Кирхгофа с задачей о геодезической качения, возникающей при качении однородных многообразий $G/K$, снабженных $G$-инвариантной метрикой, по их касательным пространствам. Показано, что между этими двумя задачами существует замечательная связь, проявляющаяся в общей изоспектральной кривой в алгебре Ли $\mathfrak g$ группы $G$. По ходу рассуждений будет также раскрыта роль кривизны для теории эластик.

Mobile Air Conditioning System Refrigerant Emissions Estimate for Mobile Air Conditioning Refrigerants
Authors:   Interior Climate Control Vehicle OEM Committee
Published: September 2023

The system emissions chart contained herein is intended to serve as a means of estimating the annual refrigerant emission rate (grams per year) from new production A/C systems equipped with specified component technologies. It provides emission values for various component technologies that are currently available and can be expanded as new technologies are commercialized. This document provides the information to develop an Excel file template system emissions chart for system emission analysis. The chart includes automotive compressor technologies for conventional mobile air conditioning systems, as well as those using semi-hermetic compressors. Fully hermetic compressors contain the working electric compressor within a welded housing that allows little if any typical emissions and the emission value for this type of compressor is added as low, fixed value. This standard can be considered a companion document to SAE J2763. SAE J2727 estimates system emissions, taking into account production assembly variation and accounts for components that are 100% helium leak tested prior to vehicle final assembly. The results from SAE J2064 are used to better represent permeation emissions from different hose material and coupling configurations in this version. SAE J2763 may be used to quantify emissions from properly assembled systems.

This estimate is does not apply to systems that use sealing technology that has not been characterized and included in the spreadsheet calculation, such as R-744 sealing designs.

Mieke Matthyssen: Ignorance is Bliss—The Chinese Art of Not Knowing
Authors: Gao Zhipeng
Published: September 2023

Matthyssen’s monograph has an intriguing title: Ignorance is Bliss: The Chinese Art of Not Knowing. The art of not knowing is encapsulated in a pithy Chinese expression: Nande hutu (难得糊涂), which literally translates to “Hard to attain muddleheadedness”. In practice, Nande hutu entails deliberate performance of not knowing, or “playing dumb”, for one to cope with challenging circumstances. For example, a government official might pretend not to see corruption so as to keep a distance from it. More than a survival strategy, Nande hutu also allows one to maintain moral integrity or even achieve spiritual transcendence. As simple as the notion of Nande hutu might appear to be, it requires steadfast self-cultivation in the long run and skilful self-control during social interactions. For all these reasons, Nande hutu became a maxim that for centuries inspired Chinese individuals from varied walks of life. Capturing the sheer complexity of Nande hutu, Matthyssen treats it as the entrance into a labyrinth of Chinese philosophy, politics, social relations, and a cultural history spanning from ancient times to today.
Dissolution of the Self
Authors: Rošker Jana S.
Published: September 2023

This article explores the connection between digital technology and privacy and intimacy in Europe and the Sinophone regions, with a particular focus on the changing role and constitution of human personhood. It argues that digital technology has fundamentally altered the ways in which individuals construct and maintain their personal boundaries, resulting in the erosion of traditional notions of the human self. Through an analysis of cultural and historical factors, the article demonstrates how this phenomenon manifests itself differently in Europe and mainland China, Hong Kong and Taiwan respectively, highlighting the specific challenges and opportunities that arise in each context. The article also considers the cultural differences between the European and Chinese cultures regarding privacy and intimacy, and the ways in which digital technology has amplified these differences. It argues that while digital technology has created new opportunities for connection and intimacy, it has also exposed individuals to new risks and vulnerabilities, including the loss of privacy and the erosion of selfhood.
Overall, the article aims to contribute to our understanding of the cultural and social implications of digital technology. It highlights the need for a more nuanced approach to the regulation of digital technology, one that takes into account cultural differences and the complex ways in which technology is reshaping our sense of self and our relationships with others.
The use of CANVAS LMS in remote academic EFL writing classes: Its benefits and limitations
Authors: Cho Youngsang , Richards Andrew , Jones Stuart
Published: September 2023

The purpose of this study is to explore how English instructors at a Korean university utilized the CANVAS learning management system (LMS) when teaching EFL academic writing classes online, and their perceptions of its effectiveness and limitations. Seventeen instructors working at a university located on the outskirts of Seoul participated. Data were collected through a survey questionnaire consisting of a combination of multiple choice, a 5-point Likert scale, and open ended questions, all of which were used as the primary data collection method. Data analysis was conducted using general qualitative analysis for the open ended questions and descriptive statistics for the multiple choice and 5-point Likert scale questions. The findings of the study indicate such tools and functions as Lecture Contents, Inbox, Announcements, Assignments, Learn Status, Assignment Comment, and Speed Grader were used frequently on CANVAS, which was also related to the instructors’ high levels of satisfaction with this LMS in the areas of sharing course content, managing a classroom (e.g., monitoring students’ learning activities and communicating with students), and administering assignments and exams. On the other hand, the instructors reported that they used such tools and functions as Collaborations and Discussion less on Canvas, which matched their relatively low satisfaction with CANVAS in writing related areas such as grading, giving feedback, sharing peer feedback, and doing collaborative writing activities. Administrational and educational implications of these findings are discussed.
Research on the Development of an Educational Model Integrating Debate and Argumentative Writing
: Focusing on face-to-face debates and online debates
Authors: Lee Ran
Published: September 2023

The purpose of this study is to develop an integrated education model of debate-argumentative writing and to specifically suggest the teaching and learning method in the model. For this, I proposed a circulative model of debating and argumentative writing including the processes of the topic formation, outline creation, debating, argumentative writing, feedback, online debating, and term paper evaluation. One of the main characteristics of this study is that the two activities circulate repetitively. In the repetition of the two activities, the target aims such as argumentative thinking skills, creativity, and speech and writing competences, can be achieved in an equally balanced manner. Another characteristic is that diverse patterns of debates such as formal debates, informal debates and online debates, are utilized for the learner’s active participation. Finally, since interactions can be strengthened between learners and a teacher, learners and learners, and learners and materials, feedback and information search can be strongly activated. For further study, intensified research is suggested regarding the analysis, as well as an effective teaching method involving the diversity of the communicative aspects in multi-layered debating message postings.

Складне прощання з імперією: практики подолання тоталітарного минулого в Україні
Authors: Кордун О.О.
Published: September 2023

Подолання тоталітарного минулого в Україні є складним багатоаспектним процесом, під час якого необхідно було паралельно і комплексно вирішувати такі завдання як декомунізація, дерадянізація та деколонізація/дерусифікація. До того ж у 90-х рр. ХХ ст. вони були частиною ще більш складних загальних процесів пострадянських трансформацій в Україні, коли у короткий період часу довелося одночасно вирішувати ще цілий комплекс інших – економічних, політичних, соціальних, світоглядних та ін. – проблем різного ступеню складності, спрямованості та інтенсивності.

На такому тлі процеси реальної декомунізації та дерадянізації виглядали мало не другорядними щодо згаданого комплексу проблем. Їх реалізація була підпорядкована необхідності легітимації незалежності і збереження територіальної цілісності держави; формуванню лояльності населення до влади та підтримки її політичного курсу.

З огляду на це, прощання з тоталітарним минулим носило компромісний характер, відбувалися стихійно, несистемно, непослідовно, без належного інформаційного, наукового та політичного забезпечення – під впливом поточної політичної кон’юнктури, породженої компромісом між посткомуністичною номенклатурою та ліберально-демократичними політиками. Ці процеси були неоднорідними в територіальному вимірі, різнилася на загальнонаціональному та місцевому рівні та визначалися динамікою співвідношення політичних сил у місцевих радах, викликаючи палкі наукові та політичні дискусії чи зазнаючи латентного або навіть відвертого саботажу та опору з боку політиків або громадян. Спостерігалося значне відставання у часі та глибині таких процесів від країн Європи, які належали свого часу до т.зв. «соціалістичного табору».

Складовими цих процесів стали реабілітація жертв політичних репресій, повернення кримських татар, повернення імен українських політичних та культурних діячів, стихійні процеси «демокомунізації» на кшталт знесення пам’ятників Леніну та іншим діячам ВКПБ-КПСС (т. зв. «ленінопад»).

Значна частина процесів деколонізації та дерадянізації, які мали б відбутися ще протягом першого десятиліття української незалежності, не є завершеними навіть на нинішньому етапі і активізувалися лише в умовах активної фази російської агресії щодо України у 2014 та 2022 р. Як наслідок, неподолане, непроговорене і не переосмислене повною мірою тоталітарне минуле часто і досі стоїть на заваді розвитку України як європейської демократичної держави.
Тоталітарний характер політичної системи сучасного Туркменістану: історико-політичний аспект
Authors: Цапко О.М.
Published: September 2023

У статті розкриваються основні ознаки сучасної політичної системи Туркменістану, які дають нам підстави стверджувати, що ця система має тоталітарний характер. До таких ознак відносяться наступні: жорстке підпорядкування всіх основних сфер діяльності туркменського суспільства, особливо економіки, тотальному контролю з боку держави; формування культу особи керівників держави; відсутність в країні будь-якої опозиції та ЗМІ, що надавали б суспільству альтернативну інформацію; грубе порушення прав людини;нинішня зовнішня політика нейтралітету, яка з часом перетворилася у політику ізоляції Туркменістану від навколишнього світу. Прикриваючись цією політикою, правлячі кола Туркменістану фактично утаємничують від світової спільноти, зокрема від міжнародних правничих організацій, інформацію про реальний стан в країні.

Вищезазначені характеристики політичної системи Туркменістану доповнюються наявністю в ній підривного політичного інституту корупції. Остання має системний характер і від боротьби з якою Туркменістан, на відміну від решти пострадянських держав, фактично відмовився.

Окрім того, більш як тридцятилітній період незалежного розвитку Туркменістану засвідчив відсутність поступу країни до демократичних цінностей. Натомість сформувався режим, який ґрунтується на інших ціннісних установках. В країні відсутня реальна демократична конкуренція, яка витіснена переважно конкуренцією кланів. А сам політичний процес у державі, спрямований на задоволення інтересів лише певної частини політичної верхівки країни за рахунок низів. Все це сприяє дедалі більшій зовнішньополітичній відособленості країни від сучасних світових глобалізаційних процесів.

Останні президентські вибори в Туркменістані загалом дозволяють нам зробити висновок про те, що в низці пострадянських країн намітилася своєрідна тенденція перетворення посади президента країни у спадкову, яка передається від батька до сина.

Theoretical Evaluation on Inelastic Lepton Scattering of Nuclear Effects.
Authors: Likta Emmanuel , Ngadda Yakubu , Yakubu Nura
Published: September 2023

Inelastic scattering is a process in which the kinetic energy of an incident particle is not conserved due to the interaction between an electron and a photon causing an unstable nuclear state. Upon the interaction of the incident photon with matter, Raman scattering occurs where the frequency of the photon shifts towards red or blue. Electron scattering of a profoundly inelastic nature emanating from protons provides the primary evidence for the presence of quarks, neutrons undergo inelastic scattering that excites the nucleus and causes it to emit corpuscular and electromagnetic particles. The aim of this work was to theoretically obtain the nuclear effect on the scattering of inelastic leptons and to observe the nuclear dependence. The methods, cross-section four-momentum transfer squared function and the Lorentz scalar product, were used. The correlation between low energy parameters and quark valence was obtained, the indicative value in quantum chromodynamics is 5% and infinite nuclear material does not lead to any finite size report. The origin of the nuclear effects is not yet evident; however, the structural functions and the effects of finite size were theoretically tested.

Authors: Maulani Irna Sari , Syamsuri Heris
Published: September 2023

Plastic waste is an inseparable part of human life. People's habit of burning accumulated plastic waste can release heavy metal content in plastic and toxic chemicals such as dioxins which can interfere with the respiratory process. There is another way to reduce plastic waste, namely by melting plastic waste into paving blocks. The process of melting plastic waste is carried out in a melting furnace. The purpose of this study is to analyze the heat transfer that occurs in the smelting furnace. The method used in this research is heat transfer analysis using FEM analysis and heat transfer analysis through experimental studies. The results obtained in the FEM analysis, the heat generated by the smelting furnace ranges from 212-300 ⁰C. While the heat generated in the measurement process is 280 ⁰C. Analysis of heat transfer that occurs in the smelting furnace obtained a figure of 1.95 Watt. The value of the wasted heat from the smelting furnace is 6.77 W. This means that the wasted heat is greater than the heat generated from the smelting furnace, this will result in a waste of energy. To overcome wasted heat, it is recommended to add insulating material to the furnace around smelting.

A vertical axis wind turbine (VAWT) is a power generator that uses wind power to generate torque. The VAWT can be pointed in any direction, meaning it doesn't need to be pointed into the wind to generate power. Thus, there is potential for large power plants using VAWTs as their size can be significantly increased. However, there are also some drawbacks to the VAWT. VAWT has the characteristics of self-starting. But still, an additional power source is needed to start the turbine rotation until a certain rotation speed is reached or it must operate at high wind speeds. The main objective of our work is to create a 5 W VAWT model (helical type) to optimize self-starting of vertical axis wind turbines. The outline of this report is regarding the design of our VAWT model, which will have self-starting characteristics. To increase the self-starting status, our efforts are to optimize the type, dimensions and material of the turbine blades. We also optimized the rotor dimensions. As a result, a model helical three-blade turbine was built and tested. The blade turbine made of composites has been balanced with the rotor prior to testing. The test uses 2 fans with a speed of 3-5m/s, the test is carried out to obtain wind turbine performance data.

Published: September 2023

In an effort to evaluate the current use of case studies as a teaching technique in postsecondary agricultural education and to develop a model for integrating technologies into the case study technique (CST), a qualitative study was conducted that explored the current use of case studies, examined the effectiveness of the technique, and explored the technology skills held by instructors. Study findings revealed benefits and limitations to the use of CST within postsecondary agricultural education as well as methods for integrating technology into the process. Benefits of CST to students included (a) preparation for real-world application of knowledge, (b) development of higher-order thinking skills, and (c) communication skills improvement. Limitations of CST included (a) students’ lack of prior experience, (b) difficulty for instructors to find quality cases, and (c) the need for skilled facilitators. Ways to address these limitations were identified through the research and involved the integration of technology. Research findings provided a foundation for the development of a model to integrate technology with CST. While further research is needed to confirm the effectiveness of the model, the research implies that the use of the resulting model could increase the use of CST and improve teaching effectiveness.

Urge incontinence and childhood nocturnal enuresis are two related urinary conditions that significantly affect individuals and their quality of life, varying prevalence between age and obesity. This systematic review examines the literature on the relationship between childhood nocturnal enuresis and urge incontinence in adulthood, including the potential mechanisms linking these conditions. Ten studies met the inclusion criteria and were included in the review. The results showed a consistent association between childhood nocturnal enuresis and urge incontinence in adulthood. The pooled analysis demonstrated that childhood nocturnal enuresis was a risk factor for adult urge incontinence, with odds ratios ranging from 1.75 to 2.7. This relationship’s potential mechanisms include nocturnal polyuria, detrusor overactivity, and arousal thresholds. However, the exact mechanisms still need to be fully understood and further investigated. Clinical implications of these findings suggest the importance of early identification and intervention for childhood nocturnal enuresis to potentially reduce the risk of developing urge incontinence in adulthood. Future research should focus on longitudinal studies to better understand the association between these conditions and explore potential risk factors and preventive strategies. Overall, this review highlights the need for increased awareness and management of childhood nocturnal enuresis to minimize the socioeconomic burden and improve the outcomes for individuals with urge incontinence.
