Authors: Kimpara Estevão T. , Leite Fabíola Pessoa P. P. , Valandro Luiz Felipe , Gonçalves Juliana , Bottino Marco Antonio
Published: December 2021

The present study evaluated the union resistance among the surface of the ceramic In Ceram Alumina® (Vita Zahnfabrik, Bad-Säckingen, Germany) and two different types of resin cements (Panavia F, Kuraray® e Relyx, 3M®). Six ceramics blocks were made with dimensions of 6x6x5mm following the technical guide lines wich were duplicated in composite resin (W3D MASTER®). One of the faces of the ceramic block (6mmx5mm) was sandblasted with the Rocatec system® and cemented with the two different cements under constant load of 750g to the correspondents faces composite blocks. After the storage of the samples (seven days in distilled water at 37º) each group formed by ceramic, cement and resin was split up in two axis X and Y and it were obtained specimens with adehive area of 1mm² ± 0,1. Two groups (n=27) were obtained: PanaviaF group and RelyX group. Each sample was fixed with cyanocrylate in an adapted device which was attached to a universal testing machine (EMIC) and then subjected to tensile forces at a crosshead of 0.5 mm/min and load cell of 10kgf. The results showed that the medium values of rupture (MPa) for the PanaviaF group (median=30.98 ± standart deviation=5.43) are statistically different comparing to RelyX group (median 12.48 ± standart deviation 3.54) (p-value=0.,001). The conclusion of this study was that the Panavia F had better adhesive resistance than RelyX. All fractures analyzed occurred at the adhesive zone, with no findings of cohesive fracture of the porcelain.

Published: December 2021

The aim of this study was to evaluate the occurrence of Porphyromonas gingivalis in patients with periodontitis in Brazil and investigate whether there is a relationship between your occurrence and gender and age. Analysis was performed of 1,386 results of microbiological examinations of samples of subgingival microbiota in patients with periodontitis. Collection was performed by periodontists in private practice and processed by culture in clinical laboratory of oral microbiology. The chi-square test was used to verify the association of occurrence of P. gingivalis with gender and age. It was observed that 59% of examinations were of female patients and 41% were of male patients, most of which aged more than 40 years (64.3%). The occurrence of P. gingivalis was 17.8%. There was no significant difference in the presence of this bacterium in the different age ranges, yet there was a significantly higher occurrence in males. It was observed that, regardless of the age range, the occurrence of P. gingivalis was always significantly higher in males. It was concluded that the occurrence of P. gingivalis in patients with periodontitis in Brazil was 17.8% and was associated with gender, yet had no association with the age range.

Published: December 2021

A cor das resinas compostas indiretas é um dos mais importantes fatores no sucesso do tratamento protético. Com este material a estabilidade de cor é aspecto preponderante na longevidade deste trabalho. A proposta deste estudo foi avaliar a estabilidade de cor de resina composta indireta (Resilab Master, Wilcos – Brasil) através de um colorímetro digital. Foram confeccionados 32 corpos-de-prova (CP). Realizou-se o registro inicial da cor de cada CP, através de um colorímetro digital, que foram distribuídos em 4 grupos (n=8) e imersos em diferentes soluções. Grupo 1 (controle): água destilada/estufa; Grupo 2: água destilada/termociclagem; Grupo 3 : suco de laranja/termociclagem e Grupo 4: café/termociclagem. Após termociclagem e imersão em estufa (tempo total aproximado de 60 horas), as amostras foram enxaguadas e o registro final da cor foi obtido. Os dados foram submetidos à análise estatística (Teste de Dunnet – p<0,005). Os resultados mostraram que os valores de ΔE (diferença de cor) e desvio padrão dos grupos foram: G1: 2,35±0,84; G2: 2,97±1,21; G3: 8,33±5,87; G4: 22,38±5,33. Foi observado que os grupos 3 e 4 diferiram estatisticamente do grupo 1, exceto o grupo 2 que não foi estatisticamente significante. Baseado nos resultados, conclui-se que a termociclagem contribui para uma alteração de cor da resina composta indireta e a solução de café mancha mais do que o suco de laranja.

Published: December 2021

A técnica de clareamento em consultório com peróxido de hidrogênio em forma de gel, pode ter seu tempo clínico diminuído após exposição a diferentes fontes de luz. Este trabalho avaliou a ação de diferentes fontes de luz na microdureza do esmalte dentário bovino, submetido a clareamento com peróxido de hidrogênio à 35% (Opalescence® XTRA). Foram utilizadas 20 coroas de incisivos, seccionadas em quatro fragmentos e incluídos em resina acrílica. Posteriormente, foi realizado o aplainamento da superfície. As amostras foram divididas em quatro grupos de estudo: laser de diodo (grupo A), LED (grupo B), sem ativação por luz/ controle (grupo C) e laser de Nd:YAG (grupo D). A leitura da microdureza das amostras foi realizada antes e após o tratamento clareador, obtendo-se assim a 1ª e 2ª leituras, respectivamente. Em seguida, as amostras foram armazenadas em saliva artificial por 14 dias à ±37°C, sendo tomada uma 3ª leitura da microdureza após esse período. A análise estatística ANOVA e o teste de Tukey revelaram diferença estatística entre a 1ª e 2ª leitura, nos quatro grupos estudados. Os grupos A, B e C mostraram diferença significativa entre a 1ª e 3ª leitura, com exceção do grupo D. Concluiu-se que o tratamento realizado sem ativação por luz ou com LED, levou a mesma alteração da microdureza do esmalte. O laser de diodo alterou a dureza da superfície de esmalte sem recuperação da microdureza após 14 dias. No grupo do Nd:YAG houve aumento da microdureza da superfície após o período de armazenamento.

Published: December 2021

This study evaluated the effect of desensitizer and rewetting agent on dentin shear bond strength. One hundred thirty five bovine incisive teeth had their buccal surfaces ground down to produce a fl at superficial dentin surfaces and received the following treatments: G1- One Step Plus (OSP) and resin cylinder adhesive fi xation (RI); G2- Gluma One Bond (GOB) and RI; G3- Single Bond (SB) and RI; G4- Aqua-Prep (AP) + OSP and RI; G5- Gluma Desensitizer (GD) + GOB and RI; G6- GD + SB and RI; G7- GD + OSP and RI; G8- AP + GOB and RI; G9- AP + SB and RI. The specimens were stored at 37°C and 100% humidity for 24 hours and a shear bond test was performed with a mechanical testing machine, at a crosshead speed of 0.5 mm⁄min. The data were submitted to one-way ANOVA followed by the Tukey test (p<0.05). The results (MPa) were: G1: 10.75(2.64)a; G2: 10.28(2.58)a; G3: 11.63(4.59)a; G4: 10.93(4.88)a; G5: 10.15(3.95)a; G6: 11.82(4.14)a; G7: 9.85(2.15)a; G8: 5.48(1.94)b; G9: 10.62(2.83)a. The resistance of the GOB adhesive system was negatively affected by AP application. The use of desensitizer and rewetting agent does not compromise the bond strength when they are compatible with the adhesive system used.
Avaliação da influência da espessura e da posição relativa de materiais simuladores de tecidos moles na densidade óptica de radiografias periapicais da região posterior da mandíbula

Published: December 2021

Para avaliar a infl uência da espessura e da posição relativa de materiais simuladores de tecidos moles na densidade óptica de radiografi as periapicais da região posterior da mandíbula, foram realizadas três radiografi as padronizadas de peça anatômica antes e após a dissecação dos tecidos moles, da peça óssea com a interposição vestibular de músculo bovino (20mm), cera utilidade, resina acrílica autopolimerizável e parafi na nas espessuras de 20, 25 e 30mm e da peça óssea com interposição do mesmo material nas seguintes combinações: 5+15 e 10+10mm, sendo o primeiro número referente à espessura do simulador localizado por vestibular e o segundo por lingual. As radiografi as foram digitalizadas e então submetidas à análise da densidade óptica de uma área padronizada. As médias e desvios-padrão da densidade óptica de todos os grupos foram comparadas através da análise da variância, complementada pelo teste de Tukey (α=5%). Omúsculo bovino não reproduziu fi elmente os efeitos dos tecidos moles da região posterior da mandíbula na densidade óptica da imagem radiográfi ca. Quando interposto somente por vestibular, o simulador que mais reproduziu a densidade óptica dos tecidos moles foi a cera, nas espessuras de 25 e 30mm. A posição do material simulador em relação à peça óssea interferiu na densidade óptica resultante. Quando interpostos por vestibular e lingual, o acrlílico em duas lâminas de 10mm de espessura, a parafi na e a cera com lâminas de 5 mm por vestibular e 15mm por lingual foram as combinações que resultaram em densidade óptica que não diferiu signifi cativamente daquela da peça com tecidos moles.

Published: December 2021

O anticorpo monoclonal (Acmo) anti-Streptococcus mutans 56G foi analisado quanto ao efeito na aderência e crescimento da placa bacteriana in vitro, e quanto ao crescimento em caldo e no comprimento da cadeia do estreptococo. O Acmo foi purifi cado em proteína A - Sepharose e testado em ELISA frente a quatro cepas de S. mutans (ATCC 35668, SP, GS5, CD28A). O Acmo reconheceu com maior intensidade a cepa GS5. As placas bacterianas formadas in vitro na presença do Acmo apresentou menos carboidrato total (polissacarídeo extracelular) que o grupo controle e essa diferença foi signifi cante (p>0,001). A placa bacteriana do grupo tratado, formada sobre uma lamínula de vidro, era diferente da placa controle e apresentava agregados menores que cobriam a lamínula quase completamente. O Acmo 56G não infl uenciou o crescimento bacteriano, nem o comprimento da cadeia de S. mutans.Os resultados desse trabalho sugerem que o Acmo testado deve reconhecer a glicosiltransferase (GTF) de S. mutans presente na superfície bacteriana, interferindo na síntese de glucano por essa enzima.

Published: December 2021

A angiogênese tumoral tem sido associada com a agressividade das neoplasias, inclusive nos carcinomas da cavidade oral. O objetivo deste trabalho foi avaliar a correlação existente entre o índice angiogênico e o grau histológico de malignidade em 8 casos de carcinomas de células escamosas de lábio inferior e 10 de língua, analisados segundo o sistema recomendado por Bryne (1998) e classificados como de alto e baixo escore conforme Anneroth et al. (1986). A vascularização foi mensurada através da contagem das células endoteliais imunocoradas pelos anticorpos FvW e CD31 em cinco campos de maior densidade vascular na profundidade tumoral. Os resultados constataram que a marcação com o anticorpo FvW foi mais homogênea e eficiente (100% dos casos positivos), que o CD31 (55,5% de positividade). Não foi evidenciada correlação significativa entre a contagem microvascular (MVC) e a gradação histológica das lesões em ambas localizações. Estes resultados sugerem que a avaliação da angiogênese tumoral não representa um bom marcador para avaliação do comportamento biológico de carcinomas de células escamosas de lábio inferior e língua.

Published: December 2021

Foi analisada a aplicação clínica de dois métodos para estimativa da maturidade esquelética por meio da observação das vértebras cervicais. Telerradiografias em normal lateral e radiografias de mão e punho de 220 pacientes com 9 a 16 anos de idade (107 do gênero masculino e 113 do feminino), foram interpretadas por examinador calibrado segundo os métodos de Baccetti et al. e Hassel & Farman, bem como pelo método de Martins para ossos de mão e punho. Testes de correlação e Kappa (κ) intra-examinador foram utilizados para análise da precisão das estimativas. O dimorfismo entre gêneros foi investigado com a utilização de testes Qui-Quadrado (α = 0,05). Foram obtidos coeficientes de correlação elevados (Rs > 0,70; p < 0,001) e índices κ de 0,70 a 1,00. O dimorfismo foi inicialmente comprovado por ambos os métodos de vértebras na idade de 11 anos. Conforme o método de Baccetti et al., 50% dos meninos foram classificados no estágio CVMS II (p = 0,012), enquanto que aproximadamente 89% das meninas encontravam-se nos estágios CVMS III e CVMS IV. Pelo método de Hassel & Farman, 71,4% dos meninos estavam na fase de Aceleração (p = 0,000), sendo que 36,8% e 26,3% das meninas encontravam-se nas fases de Desaceleração (p = 0,011) e Maturação (p = 0,037), res-pectivamente. Os métodos estudados demonstraram boa reprodutibilidade. Houve dimorfismo nas idades de 11, 12 e 13 anos, pelo método de Hassel & Farman. De acordo com o método de Baccetti et al., diferenças significativas ocorreram nas idades de 11 e 13 anos.

Os portadores da hipertensão arterial sistêmica apresentam uma tendência à perda óssea devido às alterações no me-tabolismo do cálcio. O objetivo deste trabalho foi avaliar e comparar as porcentagens das áreas cortical, trabecular e do canal medular em ratos hipertensos (SHR) e normotensos. Foram utilizados 24 ratos, sendo 12 SHR (6 machos e 6 fêmeas) e 12 normotensos (6 machos e 6 fêmeas). Após o sacrifício e dissecção do fêmur direito, foi realizado um corte transversal (aproximadamente 1mm de espessura) na região de maior diâmetro do osso e o material imerso em hipoclorito de sódio 2% para retirada do tecido mole. As peças foram fotografadas em um estereomicroscópio e as imagens submetidas ao programa Image-J® para mensuração (em mm2) das áreas cortical, trabecular e do canal medular. Os valores encontrados foram transformados em porcentagens e submetidos à ANOVA e ao teste de Tukey (5%). Verificou-se que o valor de porcentagem do canal medular foi maior nos ratos hipertensos, tanto machos (p=0,02) quanto fêmeas (p=0,01). Em relação às médias das porcentagens das áreas cortical e trabecular, os animais hipertensos apresentaram valores menores, embora não estatisticamente significativos. Também não foram encontradas diferenças significativas entre machos e fêmeas. Concluiu-se que os animais hipertensos machos e fêmeas apresentaram aumento da porcentagem da área do canal medular, provavelmente em conseqüência à redução dos ossos cortical e trabecular, o que sugere um aumento na reabsorção óssea nos hipertensos.

Published: December 2021

A proposta deste trabalho foi avaliar radiograficamente 1000 dentes tratados endodonticamente e restaurados com contenção intra-radicular, analisando a qualidade do tratamento, relacionando os com a presença de alteração apical. As imagens radiográficas foram digitalizadas e, então, feita a análise, que teve como critério de tratamento endodôntico satisfatório, quando canais obturados de 1 a 2 mm aquém do ápice radicular, massa obturadora homogênea e material obturador remanescente de no mínimo 3mm. O pino foi considerado satisfatório, quando ocupava 2/3 do remanescente dental ou no mínimo o comprimento da coroa clínica, e o diâmetro apresentasse 1/3 do diâmetro da raiz. O Espaço entre o pino e tratamento endodôntico, a descentralização do pino em relação ao longo eixo da raiz, a trepanação e a fratura radicular, foram considerados como pinos insatisfatórios. Lesões periapicais foram identificadas quando da presença de espessamento ou de área radiolúcida no ápice radicular. Ao final deste estudo, foi possível observar a relação, estatisticamente significante, entre tratamentos endodônticos insatisfatórios e lesão periapical, porém não foi observada esta relação entre pino insatisfatório e lesão periapical.

Authors: Attia Mazen Ahmed , Ebeid Kamal Khaled
Published: December 2021

Objective. The aim of this study was to evaluate the effect of decontamination methods on shear bond strength of resin cement to translucent monolithic zirconia. Material and Methods. Eighty 4-mol yttria-stabilized tetragonal zirconia polycrystal specimens were fabricated. All specimens were subjected to saliva contamination and divided into four groups (n=20) according to the decontamination methods: 70% isopropanol (AL); zirclean (ZC); 5.25% sodium  ypochlorite (NaOCL); and no cleaning (NC). All specimens were bonded by using self-adhesive resin cement. Half of the specimens in each group (n=10) were subjected to thermocycling. All specimens were subjected to shear bond strength test in a universal testing machine. Failure modes were evaluated by using a scanning electron microscope (SEM). The data obtained were statistically analyzed by using one-way ANOVA followed by the HSD Tukey test (P < 0.05). Results. ANOVA test revealed a significant difference among the different decontamination methods (P < 0.05). No significant differences were found among NaOCL, ZC, and AL groups as revealed by the HSD Tukey test (P > 0.05). The effect of thermocycling was significantly different in all groups (P < 0.05); whereas, no significant difference was found in group ZC (P > 0.05). (SEM) analysis showed mixed failures in all groups except in group NC where only adhesive failure was observed. Conclusion. Saliva contamination during clinical evaluation significantly decreases the shear bond strength between self-adhesive resin cement and translucent monolithic zirconia. The cleaning gel has an impact on improving the bond strength between resin cement and translucent monolithic zirconia.

Cancer Risk in Patients With and Relatives of Serrated Polyposis Syndrome and Sporadic Sessile Serrated Lesions
Authors: Kanth Priyanka , Yu Zhe , Keener Megan B. , Koptiuch Cathryn , Kohlmann Wendy K. , Neklason Deborah W. , Westover Michelle , Curtin Karen
Published: December 2021

INTRODUCTION:

Patients with serrated polyposis syndrome (SPS) and their first-degree relatives (FDRs) have increased colorectal cancer (CRC) risk. Patients with sporadic sessile serrated lesion (SSL) have risk for progression to CRC. Yet familial risks of common extracolonic cancers and even CRC in these cohorts are poorly understood. Our aim was to examine cancer risk for patients with SPS and sporadic SSL and their close and more distant relatives using a large population database.

METHODS:

Patients with SPS (n = 59) from hereditary patient registries were eligible for study. Sporadic SSL (n = 754) and sex- and age-matched normal colonoscopy controls (n = 1,624) were selected from clinical data linked to the Utah Population Database. Cox models adjusting for the number of relatives, degree of relatedness, and person-years at risk were used to estimate CRC, extracolonic, and any-site adenocarcinoma/carcinoma cancer risk in patients and their relatives.

RESULTS:

Compared with controls, CRC risk was elevated 10-fold in patients with SPS (P = 0.04) and 5-fold in their FDRs (P = 0.001). Any-site adenoma/carcinoma risk was increased 2.6-fold in FDRs of patients with SPS. No elevated risks of other common extracolonic cancers were observed in SPS and family members. The FDRs, second-degree relatives, and third-degree relatives of patients with both SSL and adenomatous polyps exhibited a 50% increased CRC risk.

DISCUSSION:

Patients with SPS and their FDRs have an increased CRC risk, confirming other reports. Interestingly, patients with SSL were noted to have an increased risk of prostate cancer. Relatives of individuals with both sporadic SSL and adenomas, irrespective of size or dysplasia on examination, may have an elevated CRC risk, suggesting closer colonoscopy surveillance in this population.
A needs survey of overseas Irish language learners
Authors: Connolly Ronan
Published: December 2021

The vast majority of endangered languages are expected to have vanished
from community use within one to two generations (Lackaff & Moner,
2016). One such language, Irish, may die out as a vernacular within a decade
in the Irish-speaking regions of Ireland (Ó Giollagáin & Charlton,
2015). However, there is growing interest in the Irish language overseas,
particularly in the USA (Schwartz, 2020). In this study, a survey was
conducted with 92 respondents to identify the needs of learners living
outside of Ireland. The findings of this needs assessment suggest that
overseas Irish learners would benefit from the provision of an online Irish
language community that connects members through communicative and
collaborative language activities. Positioned in the context of similar
developments and innovations internationally (e.g. Henry, Carroll, Cunliffe,
& Kop, 2018), this research builds on existing literature in online
sociocultural language learning.
The challenges of dynamic teacher training for a short English for
academic purposes course when using multimodal digital platforms: a case
study
Authors: De Lima Guedes Karla K. , Mar-Molinero Vanessa
Published: December 2021

Despite the benefits of multimodal technology in the language classroom
and common practice to introduce digital tools in language teaching,
research has shown that many language teachers do not feel confident to
engage with and create online multimodal learning resources and
environments. This exploratory study examines data from five experienced
English for Academic Purposes (EAP) teachers and discusses the dynamic
challenges faced when training them to engage with multimodal teaching,
learning, and assessment methods, such as digital learning, confidence and
community building, and supporting them in creating multimodal learning
resources. It also discusses the Dynamic Teacher Training model developed as
a result of this experience to support teachers in developing the skills
they needed to fully engage with the different digital teaching tools and
teacher feedback on this.

Authors: Hassan Xavière , Eardley Annie , Combe Christelle
Published: December 2021

Undergraduate language students from the Open University (OU) and master’s degree students from Aix-Marseille Université (AMU) participated in an innovative Virtual Exchange (VE) as part of our institutions’ internationalisation at home strategy. Due to the pandemic, the one-week Residential School (RS) abroad, which is part of the Bachelor of Arts (BA) in modern languages at the OU, was replaced with an Alternative Learning Experience (ALE) – a one-week online intensive programme which included a VE. Its objectives were to support the development of OU students’ French oral skills, and the professionalisation of AMU students, by developing their pedagogical and digital skills. Qualitative and quantitative data collected showed a high level of participants’ interaction and collaboration, and positive feedback highlighting an increase in motivation and confidence to speak French (OU students) and a valued experience in developing professional ethos, and digital teaching skills (AMU students).
Developing intercultural communicative competence in the ClerKing
telecollaborative project
Authors: Madden Oneil , Ashby Soyini
Published: December 2021

Living in the 21st century means living in an era that is increasingly
globalising where cross-cultural communication is essential; thus, students
should be given opportunities to cultivate their Intercultural Communicative
Competences (ICC). This paper reports on Phase 3 of ClerKing, a
Franco-Jamaican telecollaborative project, which involved Applied Foreign
Languages (AFL) students of English from Clermont Auvergne University (UCA),
France, and students of French from the University of the West Indies (UWI),
Mona, Jamaica. WhatsApp and videoconferencing were used to facilitate the
interactions. Using the exploratory approach, we seek to identify different
parameters of ICC, relying on Byram’s (1997) and Deardorff’s (2006) models.
Preliminary findings show that students demonstrated and developed ICC such
as openness and curiosity, culture-specific knowledge, an understanding of
worldviews, sociolinguistic awareness, flexibility and adaptability, and
negotiation of meaning. However, time difference, personal and academic
schedules, connectivity issues, and misjudged/misinterpreted communication
can lead to intercultural conflict.
Intelligent personal assistants and L2 pronunciation development: focus
on English past -ed
Authors: Moussalli Souheila , Cardoso Walcir
Published: December 2021

This study investigates an Intelligent Personal Assistant’s (IPA)
ability to assist English as a Second Language (ESL) learners in developing
their phonological awareness, perception, and production of the allomorphy
in regular past tense marking in English (e.g. talk[t], play[d] and
add[ɪd]). The study addresses the following questions: Can the pedagogical
use of IPAs improve learners’ pronunciation of -ed allomorphy in terms of
phonological awareness, perception, and production? What are learners’
attitudes toward IPAs? The results suggest that participants improved in
their ability to articulate their phonological awareness regarding the
target form, and that their attitudes toward the technology was positive in
terms of the four measures adopted to assess their experience (i.e.
learnability, usability, motivation, and willingness to use). We discuss
these findings and emphasize the pedagogical potential of IPAs for the
development of L2 pronunciation, as well as their ability to personalize
learning and consequently extend the reach of the language
classroom.

The HERO project aims to develop a training program for caregivers to be
working in the elderly care sector. The program is particularly addressed to
caregivers from Middle Eastern and African countries as refugees and intends
to help them integrate into European society. This paper seeks to offer an
overview of the project, including its objectives, underlying principles,
and deliverables. The paper particularly portrays the second intellectual
output (O2) of the project, namely the ‘On the job’ training in language and
terminology curriculum, which has been developed as the end product of O2.
Initially, the methodology adopted to create learning material for language
learning in a specific-purpose context is analyzed. Based on this, the paper
provides a description of the content development by justifying and
showcasing the learning material and laying out the logic behind this,
through the trainers’ guide. E-learning tools have been integrated in the
course material, which also justifies the methodology applied for the
purpose of this project.

acquisition, is a major tool to learning Languages for Specific Purposes
(LSP) necessary to students’ professionalization. One current area of
research is digital game-based language learning because of its motivating
qualities. This paper discusses electronics students’ acquisition of
specific vocabulary as related to the free game-based collaborative platform
Check Your Smile (CYS), which is entirely devoted to learning LSP
terminology. CYS aggregates various types of games that automatically
generate individualized game plays, drawing upon a collaboratively
constructed multilingual dictionary. The study focuses on multiple variables
including attending a selective engineering course taught in English and the
language used to teach the mandatory electronics class. Empirical data shows
that students having used CYS tend to obtain better vocabulary test scores
than students who did not.

Metagenomic insights into plant growth promoting genes inherent in bacterial endophytes of Emilia sonchifolia (Linn.) DC
Authors: Urumbil Sithara K , Anilkumar M
Published: December 2021

Studies on the genome of endophytes reveal the metabolic potential of endophytic microbiome including both culturable and unculturable fractions. The metagenome analysis through the Illumina HiSeq platform gives access to the genetic data encrypted for the molecular machinery, which takes part in plant growth promotion activity of the endophyte in various aspects including production of plant growth hormones and enhancing nutrient availability for the host plant. The present work was undertaken to identify the genes involved in plant growth promotion activities from the endophytes of Emilia sonchifolia(Linn.) DC. through metagenome analysis. Metagenomic studies include the analysis of functional annotations which aid in the detection of biocatalysts taking part in the metabolic pathway of host plants. The annotations of expressed genes in different databases like NCBI Nr, KEGG, eggnog and CAZy resulted in enlisting the vast array of information on the genetic diversity of the endophytic microbiome. The metagenome analysis of endophytic bacteria from the medicinal plant E.sonchifolia unveiled characteristic functional genes involved in plant growth promotion such as nitrogen metabolism (nif) and siderophore production (enterobactin category), ipdC and tnaA (IAA producing), ACC deaminase coding genes (regulation of elevated ethylene levels in host tissues), Mo-Nitrogenase, nitrous-oxide reductase (nosZ), nitrate reductase (narG, napA), nitrite reductase (nirD) (nutrient assimilation and absorption) enterobactin siderophore synthetase components F and D and acid phosphatase genes. This clearly explains the effective plant-microbe relationship and the role of bacterial endophytic microbes in regulating the growth of host plants.

Kalki semantyczne, strukturalne i kolokacyjne z języka rosyjskiego w gwarach polskich na terenie Rosji
Authors: Skorwid Sergiej
Published: December 2021

W artykule przedstawiono rozważania dotyczące systemu leksykalnego polskich gwar przesiedleńczych w Rosji, który uległ silnemu wpływowi dominującego języka ich otoczenia. Autor omawia zagadnienia związane z wyodrębnieniem semantycznych i strukturalnych kalk w tych gwarach i w szczególności z rozróżnieniem kalk i adaptowanych zapożyczeń z języka rosyjskiego. Te problemy powstają na skutek bliskiej pokrewności kontaktujących się słowiańskich odmian językowych. W celu rozwiązania części tych problemów, uwzględniając fakt, że w wielu przypadkach kalki i/lub adaptowane zapożyczenia używane są w ściśle określonych kolokacjach, w artykule zaproponowano wprowadzenie pojęcia „kalki kolokacyjne”, które, zdaniem autora, pozwala na adekwatny opis badanych zjawisk.

Published: December 2021

Multiple methodologies have been reported to facilitate skin-derived precursor (SKP) growth, but the impact of plating density on SKP growth has not been studied. To determine the optimal plating density, we used six plating densities and two types of flasks for mouse SKP (mSKP) culture. On the 14th day, the number, diameter, and viability of mSKP spheres were compared by morphological assessment and cell counting kit 8, and we found the optimal plating density was 2.5 × 105–5 × 105 cells/mL. In addition, we investigated the correlation between the SKP spheres and the adherent cell colonies in the serum-free culture system. We treated the adherent cell colonies with two culture conditions and characterized the cells generated from two conditions by immunocytochemistry and induced differentiation, respectively. The results elucidated that the adherent cell colonies differentiated into either mSKPs or dermal mesenchymal stem cells under appropriate culture conditions. In conclusion, mSKP spheres differentiated from the adherent cell colonies. The optimal plating density significantly promoted and advanced the proliferation of adherent cell colonies, which optimized mSKP growth and yield. The adherent cell colonies possessed the capacity of differentiating into different types of cells under appropriate culture conditions.
ITGB5 mutation discovered in a Chinese family with blepharophimosis-ptosis-epicanthus inversus syndrome

Published: December 2021

Blepharophimosis-ptosis-epicanthus inversus syndrome (BPES) is a rare autosomal-dominant genetic disorder, and mutations in the forkhead box L2 (FOXL2) gene are one of the major genetic causes. As this study shows, there are many patients with BPES who do not have FOXL2 mutations, as the screening results in all family members were negative. Using whole-exome sequence analysis, we discovered another possible mutational cause of BPES in integrin subunit beta 5 (ITGB5). The ITGB5 mutation (c.608T>C, p.Ile203Thr) appears in the base sequence of all BPES+ patients in this family, and it appears to be a three-generation-inherited mutation. It can cause changes in base sequence and protein function, and there may be cosegregation of disease phenotypes. ITGB5 is located on the long arm of chromosome three (3q21.2) and is close to the known pathogenic gene FOXL2 (3q23). This study is the first to report ITGB5 mutations in BPES, and we speculate that it may be directly involved in the pathogenesis of BPES or indirectly through the regulation of FOXL2.
Simulation and Visualization of the electrical Activity of the Heart with focal ventricular tachycardia in a 3D Model
Authors: Quester Christian , Heinke Matthias , Hörth Johannes
Published: December 2021

Patients with focal ventricular tachycardia are at risk of hemodynamic failure and if no treatment is provided the mortality rate can exceed 30%. Therefore, medical professionals must be adequately trained in the management of these conditions. To achieve the best treatment, the origin of the abnormality should be known, as well as the course of the disease. This study provides an opportunity to visualize various focal ventricular tachycardias using the Offenburg heart rhythm model. Modeling and simulation of focal ventricular tachycardias in the Offenburg heart rhythm model was performed using CST (Computer Simulation Technology) software from Dessault Systèms. A bundle of nerve tissue in different regions in the left and right ventricle was defined as the focus in the already existing heart rhythm model. This ultimately served as the origin of the focal excitation sites. For the simulations, the heart rhythm model was divided into a mesh consisting of 5354516 tetrahedra, which is required to calculate the electric field lines. The simulations in the Offenburg heart rhythm model were able to successfully represent the progression of focal ventricular tachycardia in the heart using measured electrical field lines. The simulation results were realized as an animated sequence of images running in real time at a frame rate of 20 frames per second. By changing the frame rate, these simulations can additionally be produced at different speeds. The Offenburg heart rhythm model allows visualization of focal ventricular arrhythmias using computer simulations. By selecting the frame rate, the speed of the simulation results can be adjusted accordingly to visualize the electric field lines of focal ventricular tachycardias in more detail. The static and dynamic simulation results could be used in the future for teaching and research, including the training of medical professionals.
Exploitation of transition temperatures of NiTi- SMA by adjusting SLM parameters
Authors: Schuler Felix , Dany Sebastian , John Christoph , Wild Michael de
Published: December 2021

It is well known that the transition temperatures, e.g. the austenite peak temperature Ap, of NiTi Shape Memory Alloys (SMAs) can be adjusted by changing the alloy composition. This topic recently became more interesting due to the possibilities to produce SMA-parts by additive manufacturing, specifically by Selective Laser Melting (SLM). The potential of new designs and smart structures by so-called 4D-printing with locally adjusted transition temperatures Ap potentially opens up new applications and novel temperature-responsive medical devices. This work focuses on the SLM manufacturing parameters exposure time ET (scanning speed) and laser power P and their impact on the transition temperature Ap beyond the commonly used generic process parameter energy density ED. By systematical variation of process- and scan-parameters, the impact of the P, ET, sample orientation and layer height LH as well as interdependencies between them have been studied. A wide range of transition temperatures Ap between -20°C and 70°C has been reached from one starting material by varying ET. These findings potentially allow the manufacturing of smart devices with multi-stage deformation processes in a single 4Dprinted part.
Verification of an algorithm for actin tail detection of subviral particles by comparison with expert validated data
Authors: Chowanietz Jan , Rausch Andreas , Schanze Thomas
Published: December 2021

The locomotion of subviral particles of Marburg virus has been shown to be primarily actin based. For this work, a virologist selected 14 subviral particles that show actin tails in fluorescence image sequences. Using the tracked coordinates, examination areas around these subviral particles are defined. The brightness of within the examination area behind the subviral particle is analysed. In addition, the speed of the particle in each frame is calculated to investigate potential correlations between actin activity and particle speed. The results show that actin tracks can be automatically detected and analysed. First hints of a correlation between subviral particle movement and actin activity could be gathered with the presented actin tail quantifier.

Authors: Schuhmann Ricardo M. , Rausch Andreas , Schanze Thomas
Published: December 2021

The classification of subviral particle motion in fluorescence microscopy video sequences is relevant to drug development. This work introduces a method for estimating parameters for support vector machines (SVMs) with radial basis function (RBF) kernels using grid search with leave-pout cross-validation for classification of subviral particle motion patterns. RBF-SVM was trained and tested with a large number of combinations of expert-evaluated training and test data sets for different RBF-SVM parameters using grid search. For each subtest, the mean and standard deviation of the accuracy of the RBF-SVM were calculated. The RBF-SVM parameters are selected according to the optimal accuracy. For the optimal parameters, the accuracy is 89% +- 13% for N = 100. Using the introduced computer intensive machine learning parameter adjustment method, an RBF-SVM has been successfully trained to classify the motion patterns of subviral particles into chaotic, moderate and linear movements.
