Management of Avascular necrosis of femur head with the help of Arthrox- A case study.
Authors: Mahajan Deepak , Naram Smita , Parekh Hemang
Published: December 2021

Osteonecrosis or bone infarction, which is a death of bone tissue due to interruption of the blood supply, is also called as avascular necrosis (AVN) and the most commonly affected bone is femur. Line of treatment may include some medication, bed rest, stretching, physiotherapy and surgery. As many as 20,000 people develop AVN each year, most ages between 20 and 50 commonest being in male then in female. Due to lack of promising results patient search for alternative therapies and remedies. We can apply basic principles of Ayurveda to treat any modern disease like AVN. This disease can be correlated with Asthi majja gata vata described in the Samhitas and Asthivaha srotodushti vikaras. ). In this article a male patient diagnosed as Asthi Majja gata vata is treated with Arthrox treatment which includes Virechana, Karma Basti and Hip dhara. His symptoms were assessed by two methods: Visual Analog Scale (VAS) change in pain and Harris Hip Score. Both help to ascertain overall quality of life. The patient was also given customized herbal remedies, manufactured by Ayushakti Ayurveda. With the help of this we can avoid the surgery, we can reduce the pain and we can serve a better quality of life for the patients with avascular necrosis of femur head. The recovery in this case was promising and was worth for documentation.

Published: December 2021

Diameter form an integral part of blood flow measurement. This study aimed to explore different three-dimensional (3D) printed materials to develop flow phantom models of the carotid artery in preterm newborn infants and to investigate ideal diameter measurement points using ultrasound that reflected accurate lumen diameter measurement.

Cerebral blood flow measurements data using Doppler ultrasound of the right common carotid artery from 21 randomly selected preterm infants were used to produce a 3D printed Doppler flow phantom model with three different vessel diameters. Diameters were measured by multiple observers blinded to phantom vessel characteristics and each other’s measurements. 9 measurement points were studied. Agreement between observers, inter and intra observer reliability and coefficient of variation (CoV) was examined.

Of the 63 diameter measurements, 45 (71%) were performed on flow phantoms with vessel diameter of 0.196 cm. Bland-Altman plots revealed that measurement performed using leading edge to centre (mean bias 1.8% {95%LOA -4.1% to 7.7%}) and centre to trailing edge (mean bias 1.1% {95%LOA -5.4% to 7.8%}) resulted in the most accurate lumen diameter measurements. Inter and intra-observer reliability was excellent. The mean CoV for inter observer measurements was 1.7% and intra observer measurements was 1.6% and 1.8% for each observer.

We successfully produced a 3D printed flow phantom model of the carotid artery in preterm infants and identified two measurement methods that result in reliable and accurate lumen diameter measurement. Researchers and clinicians can use this information for further studies involving ultrasound diameter measurements in small calibre vessels.
Acid Rider. Idea „komunizmu kwasowego” Marka Fishera a doświadczenie zewnętrzności
Authors: Karalus Andrzej
Published: December 2021

Acid communism pozostaje intrygującym wstępem Marka Fishera do planowanej przezeń historycznej rekonstrukcji radykalnych projektów politycznych wyrosłych na gruncie kultury psychodelicznej. Idea ta nie narodziła się w próżni, lecz stanowi konsekwencję jego poszukiwań teoretycznych. Artykuł próbuje osadzić koncepcję „komunizmu kwasowego” w szerszym kontekście, skupiając się na refleksji poświęconej doświadczeniu psychodelicznemu jako kontakcie z Zewnętrzem. Twierdzę, że istnieje zbieżność między koncepcją komunizmu kwasowego a zagadnieniami poruszanym przez Fishera w książce The Weird And The Eerie, gdzie analizuje potencjalnie transformujący szok zetknięcia z tym, co radykalnie Inne. Omówię przy tym krótko dwa fenomeny muzyczno-kulturowe, które zaistniały już po epoce psychodelii lat sześćdziesiątych. Posłużą one za egzemplifikacje trybów weird oraz eerie, obietnic przyszłości pokapitalistycznej, które nie znalazły politycznej reprezentacji i osunęły się na poziom widma niezrealizowanej przyszłości modernizmu. W końcowej części artykułu spróbuje pokazać jak zagadnienie komunizmu kwasowego wiąże się z kwestią pragnienia postkapitalistycznego oraz z Fisherowską wersją futuro-akceleracjonizmu.
Palingenetic Ultra-Nationalist Christianity: History, Identity, and the Falsity of Peripeteic Dialectics
Authors: Byrd Dustin J.
Published: December 2021

The recent upsurge of European nationalism is partially an attempt to address the ongoing identity crisis that began with the Bourgeois revolution, which expressed itself through positivistic scientism and aggressive secularization, and culminated in the post-World War II “liberal consensus”: representative democracy and free-market capitalism as the “end of history.” Due to the needs of capitalism after World War II, coupled with the liberalization and Americanization of European societies, there has been a growing presence of “non-identical” elements within Europe, which itself is reexamining the very geography of what it means to be European. In this essay, I explore the historical context of the current identity struggles that are facing Europeans. From a Critical Theory perspective, I challenge the idea that Christianity or a Christian age can be resurrected by ultra-nationalists in their attempt to combat the cosmopolitanism of Western modernity. Moreover, I demonstrate how such attempts to return to an idealized Christian identity are rooted in a false possibility: Peripeteic Dialectics, or “dialectics in reverse.”
A Critique of Poverty: Exploring the Underground of Social Philosophy
Authors: Silva Hélio Alexandre
Published: December 2021

Poverty is the primary focus of this paper; more particularly, the critique of poverty and not its mere description. It would not be an overstatement to say that one of the common grounds for poverty theories is that they describe the poor as those who systematically experience their lives in privation, namely around having the minimum when it comes to needs such as housing, food, health, education, free time, etc. There is, therefore, a theoretical and socially accepted orientation that promotes the sedimentation of a deep affinity between poverty and the minimum. Based on this reasoning, what is set on the horizon is a kind of non-explicit acceptance that the overcoming of poverty can be achieved by granting the poor something beyond the minimum, however elementary that “something extra” may be. Thus, if the experience of poverty involves some sort of lack or privation, and if this condition can be fully filled by something that has already been socially produced, then what would justify the fact that some people are able to fully fill it while others (the poor) can only secure the bare minimum? In light of this, perhaps it would be better not to question the acceptable “minimum” but, rather, to ask: Why would the notion of poverty be guided by this normative criterion? Therefore, a way of describing my broader hypothesis on poverty would be to understand that it should be measured based on the level of denial of access to what has been socially produced. The further one is from accessing social wealth, the poorer one is. Finally, this tendency toward assimilation between poverty and the minimum engenders a depressive effect on demands for social change.
Why is Life Worth Saving? Neoliberalism, COVID-19, and Boris Johnson’s Public Statements
Authors: Morelock Jeremiah , Listik Yonathan , Kalia Mili
Published: December 2021

We apply Brown’s Foucauldian framework on neoliberalism to the COVID-19 crisis in the UK, and use qualitative content analysis to interpret the moral logics within 32 of Boris Johnson’s public statements on COVID-19. We present the content analysis in six parts. For the first four parts, we apply four elements of Brown’s framework: economization, governance, responsibilization, and sacrifice. Next, we explain two other moral logics—utilitarian and sympathetic. Johnson’s condensation of logics contains ideological connotations: neoliberal rationality serves the mass of people and the purpose of sympathy. Within Brown’s conceptual framework, the problem is not just the domination of the market, but the logic that grants the market legitimation as a human-centered logic. The adjustment we suggest is in recognizing the human-centered aspect as not a veneer for neoliberalism, but rather as a collection of disparate moral logics, combined with them smoothly on the surface, but messily underneath.
Obchody rocznicy Chopina w roku 1910 a integracja narodowa. Chopin a kultura pamięci
Authors: Budrewicz Tadeusz
Published: December 2021

The article presents the events of the celebration of Chopin’s 100th birthday in 1910. The article is based on the accounts published in the daily press of the time. The growth of Chopin’s cult in Polish lands culturally connected the nation divided both politically and administratively between three countries (Austria, Prussia and Russia). Despite disruptions by the police that inhibited the organisation of the celebrations in Poznan and Warsaw, the Polish people treated them as a nation-wide occasion and used that time to integrate. The key events were the 50th anniversary of Chopin’s death (1899) and the 100th anniversary of his birthday (1910). The year 1910 was also the 500th anniversary of the Battle of Grunwald which saw the Poles defeat the Germans. Chopin’s year had immense patriotic meaning and integrated the nation living under foreign rule.
Literackość korespondencji Fryderyka Chopina
Authors: Samsel Karol
Published: December 2021

In some measure, in opposition to the contemporary studies on Chopin’s letters emphasising their non-literary character, the aim of this study is to point at the multifaceted literariness of the correspondence of the author of the Revolutionary Etude. One of its crucial aspects would be the intertextual one: Chopin’s letters constitute an intriguing community of style, including, above all, the schemes of Fredro-like comedy and Henryk Rzewuski’s gawęda szlachecka (nobility tale). The idea of writing in the spirit of disciplined lightness, rigour of formulating thoughts in a casual, colloquial and easy manner, as Wiktor Weintraub put it, affects Chopin’s planned skill of self-creation and autothematical procedures, always in similar styles that use humour for the purpose of making thing unusual, or even obscene. The arguments collected in the article force one to withdraw Ryszard Przybylski’s conviction about Chopin’s epistolography as representing the language “serving life” only outside of literature and literariness.
„W półsłowa” i „w półdźwięku”… O relacji Zygmunta Krasińskiego i Fryderyka Chopina
Authors: Hoffmann-Piotrowska Ewa
Published: December 2021

The article presents the relationship between Frédéric Chopin and Zygmunt Krasiński both on the biographical level and in the relationship between the word and the sound that Krasiński often wrote about in his letters. A special expression of the dialogue between poetry and music described by the poet are Chopin’s compositions to the words of poets contemporary to him, which is especially true about the words of the motto from Krasiński’s poem Ostatni (The last poem). It is extraordinary in the context of Chopin’s songs as it is not only a musical illustration, but also a sophisticated interpretation of the text through music. The attempts to present poetic content through musical notation presented in the article lead to the conclusion about Chopin as a conscious recipient of a literary work who, like Krasiński, saw in the symbiosis of word and sound the possibility for expressing internal experience.

Published: December 2021

Temperature has a significant influence on the action of pyrethroids, and their effect increases with decreasing ambient temperature. Using gas chromatography, we assessed the degradation rate of λ-cyhalothrin, active ingredients (AI) of Karate Zeon 050 CS from pyrethroid group, in bees incubated for 48 h under different temperature conditions. With RT-qPCR method, we studied expression levels of selected cytochrome P450 genes after exposure to the plant protection product (PPP). The half-life of λ-cyhalothrin decreased from 43.32 to 17.33 h in the temperature range of 21–31°C. In animals incubated at 16°C, the AI half-life was even shorter and amounted to 10.19 h. The increase in temperature increased the expression of Cyp9Q1, Cyp9Q2, and Cyp9Q3 in the group of control bees. We showed a two-fold statistically significant increase in gene expression after treatment with PPP bees. The obtained results indicate that honey bees are characterized by susceptibility to pyrethroids that vary depending on the ambient temperature. This may be due to the different expressions of genes responsible for the detoxification of these PPPs at different temperatures.
Carryover effect of direct-fed microbial supplementation and early weaning on the growth performance and carcass characteristics of growing Najdi lambs
Authors: Amran Ramzi A. , Alhimaidi Ahmad R. , Al-Ghadi Muath Q. , Ammari Aiman A. , Gaafar Abdel-Rhman Z.
Published: December 2021

Growing Najdi lambs were randomly selected from lambs weaned at 30, 45, and 60 days old which were treated with 3 doses of direct-fed microbial (DFM) at 5, 10, and 15 days old to investigate the carryover effect of early weaning and DFM supplementation on their growth performance and carcass characteristics. Ten lambs from each group were transferred to individual pens for a feeding trial using the total mixed ration (Wafi). Lambs treated with DFM and weaned at 60 days old showed numerically higher body weight and average daily gains compared to other groups. Concerning the carcass and meat quality, there were significant differences between all groups in all carcass and tissue measurements, except for the back-fat and body wall thickness. In conclusion, treatment did not have any significant negative effect on body weight, feed intake, and conversion ratio compared with the control, but positively affected Zn and Cu absorption. DFM also played an important role in fat metabolism, which affects fat deposits in carcasses. The most important finding was that early weaning can be performed using DFM supplementation without any negative effect on the lambs’ performance during growth.

Published: December 2021

In this article, we aim to estimate what the cost of Covid-19 has been in terms of unemployment for Spain. We use a simple autoregressive model to simulate what the unemployment rate would have been without the pandemic and we compare this with the actual values. We also forecast the unemployment rate for 2021 and 2022 to analyse the persistence of the pandemic shock to unemployment.
Understanding CLIL from an ELF perspective: language in Taiwanese primary bilingual education
Authors: Pineda Inmaculada , Tsou Wenli
Published: December 2021

Recent global developments have intensified the use of English as a lingua franca (ELF), the principal means of communication employed among speakers of different linguistic backgrounds to interact worldwide. Consequently, there has been a growing interest in the pedagogical implications and applications of ELF in language teaching and learning. Few works, though, have investigated the influence of ELF in bilingual education such as in Content and Language Integrated Learning (CLIL). The current paper describes the design and implementation of a CLIL + ELF observation tool that was used to study a pilot CLIL program in Taiwan and to anticipate CLIL teachers’ training needs. The data collected from the rubric were contrasted with several unstructured interviews. The rubric contains 10 criteria developed from previous CLIL and ELF studies including: learners’ L1 and L2 proficiency; teachers’ L2 proficiency; teachers’ ability to reflect upon their practice; their familiarity with CLIL and ELF methodologies; and the school’s commitment to bilingual education and language policy considerations. Using these criteria, the researchers identified many positive results such as teachers’ growing familiarity with CLIL and their use of class management language, content-related language, and academic communication. The study also suggests areas for improvement such as the need for teacher training regarding ELF.

Published: December 2021

The potential for pollution of rivers is influenced by river-water discharge and the distribution of pollution sources. This research aimed to examine recommendations for water quality management in the Bedadung River segment of the Patrang, Sumbersari, and Kaliwates Districts as an urban area of Jember Regency refer to simulations of the total pollution load capacity for 10 years (2016-2026) using a system dynamics modeling. The preparation of a system dynamics modeling used Powersim 5.0 software. It could represent holistic environmental management modeling. The input data were total suspended solid (TSS), biochemical oxygen demand (BOD), chemical oxygen demand (COD) and the streamflow of the Bedadung River. The model scenarios were the business of usual, moderate, and optimistic scenarios involving environmental and socio-economic aspects. The medium-term and long-term recommendations for water quality management of the Bedadung River based on system dynamics simulation were respectively moderate scenario and optimistic scenario. The strategies of the moderate scenario were application of the best management practice method in agricultural cultivation, improving sanitation and domestic wastewater treatment, implementing clean production in the field of livestock and industry, as well as waste management on riverbanks. These alternative strategies for river water quality management can be used as consideration for protecting surface water sources in urban areas.

Published: December 2021

Extensive utilization of fragile tropical peatlands ecosystem encourages a better understanding of spatiotemporal micronutrients distribution. The distribution of total Fe, Cu, and Zn in peat and their relationship with environmental factors were studied under oil palm plantation, Pangkalan Pisang, Koto Gasib, Riau, Indonesia. Peat samples were taken compositely inside the block using a combination of six factors, including a) the oil palm age (<6, 6-15, >15 years old), b) the peat thickness (< 3 and >3 m), c) season (rainy and dry), d) the distances from the secondary canal (10, 25, 50, 75, 100, and 150 m), e) the distances from an oil palm tree (1, 2, 3, and 4 m), and f) the depth of sample collection (0-20, 20-40, and 40-70 cm from the peat surface). Total Fe, Cu, and Zn were determined by the wet digestion method. These micronutrients observed in this study possessed high variability; however, they were within the expected range in tropical peatland. The entire micronutrients were statistically different by oil palm age, peat thickness, and distance from canal. Meanwhile, total Cu and Zn were also significantly different at each season. The oil palm age, peat thickness, and distance from the canal were the common factors controlling total Fe, Cu, and Zn in peat significantly. Moreover, total Cu and Zn were also dictated by season, distance from the oil palm tree, and depth of sample collection. Based on visual interpretation in PCA (principal component analysis), all micronutrients were categorized into two groups, separated by 2 m distance from the oil palm tree and 20 cm depth from the soil surface. Our study also highlights the dominance of the dilution over the enrichment process in peat, which requires further research to formulate micronutrients fertilization, especially for an extended cultivation time.

Published: December 2021

Historic mining of copper around Musina Town left behind a sizeable unrehabilitated tailing dump. This article reports on the study conducted to investigate the suitability of using copper tailings as sand replacement in recreational projects. The methodology used involved analyzing the particle size distribution and plasticity index (PI) of the tailings and determining their particle density, bulk density, particle shape, total porosity, and permeability coefficient. The pH of the tailings, major element oxides, and heavy metals composition were all analyzed. The tailings were classified as poorly graded sand with silt (SP-SM). Low fines (9.6%) and PI (1.4) values revealed that the copper tailings were texturally suitable for application in rootzones of sports fields, courts for beach volleyball, and bunkers of the golf courses. Their particle density (2.90 g/cm³), bulk density (1.53-1.89 g/cm³), porosity (34.62-47.04%), and permeability (1.42 x 10-3 cm/sec) were all within the recommended range for application in rootzones. The angular particles of the tailings supported their uses in the bunkers. However, their pH (7.9) and high quartz content (69% SiO2) confirmed their suitability for rootzones. However, the high concentration of Cu (1872.0 mg/kg) and Cr (159.5 mg/kg) was identified as a potential risk of using the copper tailings in rootzones. This and the relatively high Al2O3 (11%) and Fe2O3 (8%) suggested that the copper tailings should be first washed or processed before being used in any recreational projects. Developing a suitable technique for processing the studied copper tailings to enhance their properties for different recreational projects was recommended.

Published: December 2021

When groundwater quality is good, it may be a substantial water supply for various applications. However, no systematic research on hydrogeochemistry and water quality features for drinking and irrigation has been undertaken in the present study area. As a result, the current study looked at hydrogeochemical variables and groundwater quality for drinking and irrigation in Tercha district, Dawuro Zone, Southern Ethiopia. Forty-seven groundwater samples were collected and tested to satisfy the required target for various physicochemical properties. The hydrogeochemical features of the groundwater in the study region were assessed using in-situ testing and laboratory analysis of physicochemical parameters. Groundwater samples from the research region were slightly acidic to slightly basic, with the principal cations and anions decreasing in sequence: Na+ > Ca2+ > Mg2+ > K+ and HCO3-> Cl-> SO42-. The hadrochemical facies of the studied region evolved from mildly mineralized dominant highland Ca-HCO3 water types to moderately mineralized mixed Ca-Na-HCO3 water types to highly mineralized deep rift floor Na-HCO3 water types. Additionally, the World Health Organization and the Ethiopian Standard Agency were utilized to compare the drinking water quality. Except for NO3- (4.25 %), Fe (8.51 %), and F- (2.12%), all groundwater samples from the research region were determined to be within permitted limits and appropriate for drinking. According to the Water Quality Index, about 80.86% of groundwater samples are excellent, and 19.14% are good drinking water. Sodium absorption ratio (SAR), sodium (Na) percentage, residual sodium carbonate RSC, permeability index (PI), and magnesium hazard were among the irrigation water quality indicators calculated (MH). The great majority of groundwater samples are suitable for agricultural use.

Published: December 2021

Mycorrhizal fungi play a major role in the functioning of ecosystems. However, their identification has remained a challenge for scientific research. This study presents the first identification report of species of arbuscular mycorrhizal fungi in the rhizosphere of the halophyte Plantago coronopus L. in Algeria. Samples of rhizospheric soil were collected in spring 2018 at three sites in the Bomo-plage dunes west of Oran, Algeria. The spores were isolated by wet sieving, morphologically identified, and quantified. The mean spore density was 107.94 spores 100 g-1 dry soil, which is high compared to other dune ecosystems. Endomycorrhizal spore morphotypes were involved in the following Genus: Glomus, Septoglomus, Rhizophagus, Diversispora, Funneliformis, Dentiscutata, Claroideoglomus, Scutellospora, and Entrophospora, to the following Family: Glomeraceae, Gigasporaceae, Diversisporaceae, Claroideoglomeraceae, and Acaulosporaceae. The Glomeraceae was the most dominant identified family. The identification of indigenous arbuscular mycorrhizal fungi has been shown to be essential for future programs to restore disturbed dune ecosystems.

Published: December 2021

The image of women that is actualized through the construction of gender roles, positions, and adaptation processes in artistic expression through Sintren and Kuda Kepang performances is very different. In this regard, the research aims to: (1) explain the forms of art performances of Sintren and Kuda Kepang; and (2) explain the image of women in the art performances of Sintren and Kuda Kepang in the context of gender reality and aesthetic exploration. The research was conducted on the art of Sintren Ujung Gede in Pemalang Regency and Kuda Kepang Turonggoseto in Semarang Regency. The research data were collected using the techniques of (1) observation, (2) interviews, and (3) document studies. The validity of the research data was carried out using the confirmability technique. The study used an interactive model analysis procedure, which was carried out with the stages of data collection, data reduction, data classification, and drawing conclusions. The results show that: (1) Sintren and Kuda Kepang arts are forms of traditional folk-art performances in which there is a scene of trance. This art is usually performed on stage or open arena by involving women as players; (2) The presence of women in the Sintren performances is a requirement that traditionally must be fulfilled until now. On the other hand, in the Kuda Kepang performances, the presence of women is a new phenomenon that provides opportunities and freedom for women to express themselves through dance. In the Sintren performance, the position of women becomes the center, subject, and object during the performance process. As a result, changes in the function of arts often result in the exploitation of Sintren dancers. On the other hand, in the Kuda Kepang art, the involvement of women with all their adaptations provides a new space for resistance to the existing gender stereotypes.
Changes in Form and Style in Randai Performance at The Minangkabau Diaspora in Malaysia
Authors: Indrayuda Indrayuda , Samsuddin Mohd Effindi
Published: December 2021

This article reveals the changes in form and style of the Randai performance performed by the Minangkabau’s diaspora in Malaysia. The novelty of this research is the study of changes in forms and styles in Randai carried out by the Malaysian Minangkabau diaspora. The disconnection of socio-cultural communication and the long distance between Minangkabau and Peninsular Malaysia impacts the shift in forms and styles of Randai in the Minangkabau diaspora. This research was conducted qualitatively by designing research works such as pre-field studies, by collecting preliminary data based on a diffusion approach. In the field stage, the informants were selected by snowball sampling. The interview and observation instruments were designed based on the performance structure and performance procedures. Researchers conducted data analysis using the techniques recommended by Spradley, namely: (1) domain analysis, (2) taxonomic analysis, (3) componential analysis, and (4) discovering cultural themes. The study results revealed that the forms and styles were caused by mixing cultures between the diaspora and the Malaysian Malays. These changes were done so that the local community could accept Randai. In addition, Randai can be easily learned and cultivated by the Malay Malays and easily expressed by the Malaysian community and the Minangkabau diaspora as the perpetrators of Randai. These changes occur through a process of adaptation and acculturation. The implication of this research is the emergence of a new Randai model, namely Randai, which refers to local culture, both from the aspect of the story, Silat style, and music, as an identity and tradition for the Malaysian Minangkabau diaspora for the future.

Protetik diş hekimliğinde eksik dişlerin tedavisi için yapılan sabit protezlerde çeşitli altyapılara sahip restorasyonlar kullanılmıştır. Bunlardan en çok tercih edilen metal altyapılı seramik restorasyonlardır. Metal alt yapılı porselen sistemlerinin sahip olduğu avantajların dışında bazı dezavantajlar da mevcuttur. Sabit protetik restorasyonlarda bu eksiklikleri gidermek için metal desteksiz porselen sistemleri geliştirilmiştir. Metal-seramik restorasyon sınıflaması standardize edilip, Amerikan Dişhekimleri Birliği (ADA)’nın tüm soy metal alaşımlar için kabul ettiği sınıflama kabul edilirken tam seramik sistemler için birden fazla sınıflama mevcuttur.

Konvansiyonel metal seramik sistemlerdeki dezavantajlar, araştırmacıları farklı restorasyon arayışlarına yöneltmiştir. Estetik, alerjik sebepler ve dişeti sağlığı dikkate alındığında, elektro-kaplama sistemi ve tam seramik sistemler günümüzde konvansiyonel sisteme iyi alternatif oluşturmaktadırlar. Ni-Cr alaşımlar, yüksek gerilme direnci, yüksek sertlik, düşük maliyet ve düşük yoğunluk gibi avantajlarıyla en çok tercih edilen alaşımlardır ama kontrol edilemeyen oksit tabakası oluşumu, alerjik reaksiyon ve döküm zorluğu gibi dezavantajları da mevcuttur. Döküm altın alaşımlar ise döküm netliği, iyi fiziksel özellikler, biouyumluluk gibi avantajlarına karşın maliyetinin yüksek olması nedeniyle sık tercih edilmemektedirler. Elektro-kaplama sistemi, altın alaşımlarla karşılaştırıldığında daha düşük maliyete sahip olması ve üretim kolaylığı avantajları vardır.

Estetik ve biyouyumluluk gibi özelliklerinden dolayı zirkonya, sabit bölümlü protezlerde sıklıkla tercih edilmektedir. Mekanik ve fiziksel özelliklerinin kemik ve dentine benzerliğinden dolayı Polieter Eter Keton dişhekimliğinde birçok alanda kullanılmaktadır.

Fiber ile güçlendirilmiş rezin tutuculu köprüler, ekonomik olarak daha kapsamlı tedavileri karşılayamayan ve uzayan tedavi protokollerini kaldıramayan hastalarda, hasta başı tedavilerinde, uzun vadeli geçici sabit parsiyel protezlerde, başarılı bir şekilde uygulanmaktadır. Yapılan protetik tedavilerde; altyapı seçimi için uygun endikasyonlar ve kontrendikasyonlar göz önünde bulundurularak kullanılacak materyal değerlendirilmelidir.

Amaç: Çalışmamızın amacı; SLA yüzeyli Grade IV Titanyum disklere yapılan atmosferik basınçlı soğuk plazma uygulamasının ıslanabilirlik üzerine etkisini incelemek ve gelecek çalışmalarımızı bu etki doğrultusunda şekillendirmektir.

Gereç ve Yöntem: Çalışmamızda SLA yüzeyli titanyum diskler üzerine 5 farklı uygulama modu ve 15, 30, 45, 60 ve 120 sn olmak üzere farklı uygulama süreleri kullanılarak atmosferik basınçlı soğuk plazma uygulaması yapılmıştır. Uygulama öncesi ve sonrası gonyometre cihazı ile yüzeylere su damlatılarak kontak açısı değişimi bilgisayar programı ile hesaplanmış ve fotoğraflanmıştır.

Bulgular: Plazma uygulaması öncesi kontak açısı 1195.4 olarak ölçülmüştür. En fazla kontak açısı değişimi her modda 120 sn de görülmüştür. 1. modda 120 sn uygulama sonrası kontak açısı 35.629, 3.modda 120 sn uygulama sonrası kontak açısı 8.74, 5. modda 120 sn uygulama sonrası kontak açısı 6.82.1 saptanmıştır. Her bir zaman aralığında uygulama modları karşılaştırıldığında, uygulama öncesine göre kontak açısındaki değişim miktarı 5. Mod > 3. Mod > 1. Mod olarak belirlenmiştir.

Sonuç: Plazma uygulaması özellikle 5. Mod kullanılarak 120 sn uygulama yapıldığında ıslanabilirliği arttırmada etkili bulunmuştur ve süperhidrofilik bir yüzey sağlamıştır. Çalışmamızda kullandığımız ABSP kaynağı geçmişte kullanılan plazma cihazları aksine klinikte hasta başında kullanılabilecek bir cihaz olması nedeniyle tercih edilmiştir ve gelecekte aynı plazma kaynağı kullanılarak yapılacak olan in vitro ve klinik çalışmalarda kullanılacak olan optimum süre ve mod belirlenmesi açısından önem taşımaktadır.

Published: December 2021

Diş hekimliği pratiğinde çürük temizleme, restoratif işlemler, pulpal veya periodontal işlemler, çekimler veya küçük cerrahi işlemlerde kullanılan lokal anestezi ile belirli bir bölgenin innervasyonunu sağlayan sinir dallarının anestezisi amaçlanır. Lokal anestezikler, sinir ağları boyunca hareket ederek buradaki sodyum akışını inhibe ederler. İşlemler sırasında ağrı hissinin oluşmasını önlemek hasta ve diş hekimi arasında güven hissini oluşturmak ve korku, kaygı gibi olumsuz duyguları hafifletmekte yardımcı olmaktadırlar. Diş hekimi tedavinin gerekliliklerine göre en güvenli, en minimal invaziv ve en ön görülebilir anestezi tekniğini seçebilmelidir. Enjeksiyonun ağrılı doğasını önlemenin ve dental işlemlerden önce lokal anestezi yapılmasının daha konforlu ve keyifli bir yolunu bulmak için sürekli araştırmalar yapılmaktadır. Son zamanlarda elde edilen yeniliklere rağmen, geleneksel yöntemlerle uygulanan enjeksiyonlar lokal anestezi sağlamada ilk sıradaki yerini korumayı sürdürmektedir.

Published: December 2021

Background: The aim of this study is to explore the effect of five different plate-screw systems on the stability after LeFort I osteotomy in polyurethane skull models. Also, we aimed secondarily to evaluate the efficiency of the use of micro and bioabsorbable fixation systems especially in the regions where the muscularity is relatively thin, in providing enough stability.

Methods: Standard titanium miniplates, titanium microplates and bioabsorbable plates were applied for the internal fixation of artificially created LeFort I osteotomy on polyurethane skulls. Load applied in inferior-superior direction to simulate bite forces. The load-displacement values were recorded.

Results: Significant differences were observed among the displacement values of five fixation systems at 120, 150, 180 and 200 N of loading (p< 0.05). The highest displacement values were observed in the 4RLt-Micro group with the increasing load. The 4RLt-Mini and 4LLt-Mini groups showed the least displacement values, and the 4LLt-Mini group showed less displacement than the 4RLt-Mini group. The 2Lt/2It- Mini and 2Lt/2Ir-Mini groups showed proximate displacement values with the 4RLt-Mini and 4LLt-Mini groups.

Conclusions: The results of this study show that the left sided L miniplates provide more stable results than the right sided ones. Also, it may be said that while sufficient stability can be obtained, the problem of palpability is also eliminated with the use of bioabsorbable plates in the regions with thin muscularity in combination with standard titanium miniplates. However, further in vitro and in vivo studies with wider advancement values needs to be conducted to confirm these results.

Published: December 2021

Background: The aim of this study was to investigate the relationship between serum mercury and some plasma microRNA (miRNA) levels associated with neurological diseases in patients with amalgam filling and dentists.

Methods: This study included 30 patients with amalgam filling, 30 dentists, and 30 healthy individuals as the control group. Circulating plasma miRNAs (124-3p, 125-5p, and 127-3p) were evaluated using real-time quantitative polymerase chain reaction analysis. The serum mercury levels were measured using inductively coupled plasma-mass spectrometry. ANOVA and Tukey’s multiple comparison tests were used for statistical analyses (α =.05).

Results: A significant difference in serum mercury and plasma miRNA levels was found between the groups. Significant positive correlations between serum mercury and plasma miRNA 125-5p and 127-3p levels were detected in the patient group (r: 0.56 and r: 0.39, respectively). Serum mercury and plasma miRNA-125-5p levels showed a positive correlation in the dentist group (r: 0.37).

Conclusion: Having amalgam filling caused a significant increase in serum mercury and plasma miRNA levels. The presence of a positive correlation suggests that sensitivity to neurological diseases may increase because of mercury exposure. Alternative restorative materials should be preferred for amalgam filling and amalgam fillings should be replaced with other restorative materials under necessary preventions.

Authors: KARCI Bilge , KARCI Muhammet
Published: December 2021

Amaç: Bu çalışmanın amacı; maksiller sinüs cerrahisi öncesinde konik ışınlı bilgisayarlı tomografi (KIBT) kullanılarak Türk toplumundaki maksiller sinüs septasının görülme sıklığı, lokalizasyonu ve yönünü değerlendirmek ve bu varyasyonların yaş, cinsiyet ve dental durumla olan ilişkisini incelemektir.

Gereç ve Yöntemler: Çalışma grubu, Alanya Ağız ve Diş Sağlığı Merkezi arşivinin retrospektif olarak incelenmesi sonucu elde edilen 290 hastanın (580 maksiller sinüs) KIBT görüntüsünden oluşmuştur. Maksiller sinüs septa sayıları, KIBT görüntülerinin aksiyel kesitlerinde belirlenirken; lokalizasyon, yön ve morfolojileri hem aksiyel hem de sagittal kesitlerde belirlenmiştir. Yaş, cinsiyet ve dental durumun septa varlığı üzerine etkisi istatistiksel olarak analiz edilmiştir (p=0.05).

Bulgular: Hastaların %34.4’ünde en az bir septum görülürken, kadın ve erkek hastalar arasında anlamlı bir farklılık görülmemiştir (p˃0.05). Septumun görülme lokalizasyonu ve yönü sırasıyla; orta bölgede (%43.7) ve koronal yönde (%53.9) olarak belirlenmiştir. Septa varlığı ile yaş ve cinsiyet arasında anlamlı bir ilişki gözlenmezken (p˃0.05), dental durum arasında anlamlı bir ilişki görülmüştür (p˂0.05). Septa yönü ve lokalizasyonu ile diğer parametreler arasında da istatistiksel olarak anlamlı ilişki görülmemiştir (p˃0.05).

Sonuç: Bulunan yüksek oranlar, maksiller sinüs septa varyasyonlarının diagnozunda KIBT’nin önemini göstermektedir. Bu nedenle; maksiller arka bölgedeki cerrahi müdahalelerin başarısını arttırmak ve olası komplikasyonları önlemek için bölgenin KIBT ile değerlendirilmesi son derece önemlidir.
