The influence of extracellular matrix on human periodontal ligament stem cell properties
Authors:   , Nan Daneeya
Published: June 2024

The periodontal ligament (PDL) is a crucial tissue connecting teeth to surrounding alveolar bone, withstanding the mechanical forces of mastication, speech, and deglutition. The extracellular matrix (ECM) of the PDL plays a critical role in maintaining PDL cell stability and function in response to external forces. Mechanotransduction, the process by which cells convert mechanical signals into biochemical signals, is essential for PDL cells to sense and respond to mechanical stimuli. The ECM is a critical mediator of mechanotransduction, as it is responsible for transmitting mechanical forces to cells and regulating cellular responses to mechanical stress. Matricellular proteins, such as periostin (PN) and osteopontin (OPN), are two important components of the PDL ECM that play significant roles in regulating PDL function and bone remodeling under mechanical stress. PN is primarily located in areas exposed to mechanical loading, such as teeth and bone, and functions as a matrix-cell attachment protein that regulates cell adhesion and motility. OPN is involved in cell adhesion, migration, and biomineralization in the PDL and bone, and can regulate cellular responses to external stimulation through multiple pathways.

 This dissertation focuses on the role of matricellular proteins in outside-in signaling from the surrounding ECM, specifically in maintaining the homeostasis of PDL tissue. Firstly, we investigated the importance of the OPN protein on the osteogenic capacity of human periodontal ligament stem cells (hPDLSCs). Additionally, we demonstrated the role of PN as a mediator of hPDLSCs mechanotransduction. Finally, we extended our understanding of the profile of PDL-ECM components under the influence of mechanical force using a rat occlusal hypofunction model.

Understanding the role of the ECM in PDL mechanotransduction is critical for developing new insights into the prevention and treatment of tooth loss. Further studies are needed to fully elucidate the mechanisms underlying ECM mechanotransduction and the roles of ECM protein in regulating osteogenic differentiation, bone formation, and remodeling.
Radiosynthesis of novel 68ga-labelled-α-cyclodextrin for pet imaging
Authors:   , Sriaumpai Sirapop
Published: June 2024

Cyclodextrins (CDs) are cyclic oligosaccharides composed of glucose units linked by α-1,4 glycosidic bond. CDs are commonly used as pharmaceutical excipients and they offer versatile benefits in various industries. Recently, CDs have been promising for the application of medical imaging, especially nuclear medicine imaging. Herein, we aim to radiosynthesize 68Ga-alpha-cyclodextrin (68Ga-αCD) by directly radiolabeling Ga-68 to αCD. Briefly, Ga-68 was eluted, mixed with αCD solution and heated at 100 °C for 20 min. Subsequently, the reaction was allowed to cool down at room temperature. The resulting 68Ga-αCD was characterized using mass spectrometry (MS) and elucidated by in silico computational studies. Radioactivity was measured using instant thin layer chromatography. The radiochemical purity (RCP) was calculated. The pH of the resulting solution was measured using a pH meter. The radiosynthesis process was then optimized and purified to increase the RCP of 68Ga-αCD. The radiostabilizers, i.e., sodium ascorbate or ascorbic acid, were selected, various concentrations of αCD solutions (0.25–5 mg/ml) and αCD polymer were included to optimize the process and C-18 cartridge was employed to purify 68Ga-αCD solution. Initially, the RCP of 68Ga-αCD is very low (0.24 ± 0.03%). Upon the optimization using sodium ascorbate as radiostabilizer together with 1 mg/ml αCD solution and further purification using C-18 cartridge, the RCP is significantly increased. Ultimately, we have successfully achieved an RCP of 18.4 ± 1.1%. Subsequently, miconazole or cyclosporin A was introduced into the αCD cavity prior to radiolabeling, but no significant impact on the binding affinity between Ga-68 and αCD was observed. This is subsequently confirmed by MS and computational studies that the stoichiometry ratio of Ga-68 and αCD is 1:1 complex and binding site of Ga-68 is on either primary or secondary rim of αCD.

Published: June 2024

Objective: The purpose of this study was to examine the effect of aprotic solvents, which were tetrahydrofuran, pyridine, and morpholine, compared to hydrogen peroxide on surface roughness of fiber-reinforced composite post and microtensile bond strength between fiber-reinforced composite post surfaces and the composite core. Material and methods: A total of 75 FRC posts plus, and 75 D.T. light posts were divided into 3 groups (non-thermocycling, 5,000-cycle and 10,000cycle thermocycling groups). Each group was divided into five subgroups according to the post-surface treatment: C: non-treatment group; H2O2: immersing with 35% hydrogen peroxide; THF: immersing with tetrahydrofuran; PY: immersing with pyridine; MP: immersing with morpholine. After 1 minute of immersion, all specimens were rinsed with deionized water, dried with an air blow, silane and bonding agent application, placed in the bottom of the plastic cap, filled with composite core material and prepared specimens for the microtensile bond test. After microtensile testing, Stereo microscope was used to evaluate mode of failure on all specimens at 40x magnification. White light interferometry and scanning electron microscopy (SEM) were utilized to evaluate surface roughness for each surface treatment. A one-way ANOVA was used to analyze all of 3 groups

Authors:   , Rodmanee Nonsee
Published: June 2024

Feline blood-borne pathogens are infectious agents which knowledge of prevalence and risk factors for infection is important to recognize pathogens that should be screened in blood. A total of 298 samples (GROUP A) and 112 archived samples (GROUP B) were collected from client-owned cats attending the veterinary hospital of Chulalongkorn University, and private veterinary hospitals in Bangkok and vicinity. A total of 55 and 12 samples were positive for hemoplasmas in GROUP A and B, respectively. The species were ‘Candidatus Mycoplasma haemominutum’ and Mycoplasma haemofelis. DNA of Bartonella were detected in 10 and 12 samples from GROUP A and B, respectively. Bartonella henselae and Bartonella clarridgeiae were revealed. Risk factor analysis showed that male sex, Domestic Shorthair breed, sickness, and feline immunodeficiency virus infection were risk factors of ‘Candidatus Mycoplasma haemominutum’ infection; however, kitten was a protective factor. In addition, risk factors of any hemoplasma species infection were similar to those of 'Candidatus Mycoplasma haemominutum'. Moreover, possible risk factors for hemoplasma infection were outdoor access, mature adult or senior, anemia, and feline leukemia virus infection. The current study advocates for screening hemoplasmas and Bartonella spp. in all feline blood donors prior to blood transfusion.

Surveillance and genetic characterization of severe acute respiratory Coronavirus type 2 (SARS-CoV-2) infections in domestic animals and wildlife in Thailand
Authors:   , Jairak Waleemas
Published: June 2024

SARS-CoV-2 caused a pandemic outbreak since December 2019 with global implications for public health, economy, and society. This dissertation entitled “Surveillance and genetic characterization of severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) infections in domestic animals and wildlife in Thailand” investigates the transmission incidence and characterization of the virus between humans and animals. This thesis comprises 4 studies of the surveillance of SARS-CoV-2 in animals and wildlife species in Thailand from 2017 to 2023. The first investigation (Chapter 2) involved a survey of SARS-CoV-2 in domestic dogs and cats in Samut Sakhon province during the second wave of the COVID-19 outbreak in Thailand in February 2021. Although no viral RNA was detected in the swab samples, 3.14% (5/159) of studied animals tested positive for anti-N-IgG antibody, indicating possible SARS-CoV-2 exposure in high-risk areas. During the third wave of the pandemic, from April to May 2021, the second investigation (Chapter 3) provided active surveillance of SARS-CoV-2 among dogs and cats from COVID-19 households. The detection of SARS-CoV-2 RNA and antibodies in four of the 44 animals confirmed SARS-CoV-2 infection. According to phylogenetic analyses, the viral strains belonged to the Alpha VOCs (B.1.1.7 lineage). The third study (chapter 4) described a cross-sectional survey conducted in Bangkok and vicinities during Thailand’s 4th wave of the COVID-19 outbreak. SARS-CoV-2 infections were discovered in a dog and a cat from COVID-19 positive households. The viral genomes were classified as Delta variant (B.1.617.2 lineage). This study raised awareness of the spillover of variants of concern in domestic animals. The fourth study (Chapter 5), expanded the surveillance of wildlife species in captive and free-ranging habitats during pre and post-COVID-19 (2017 to 2023). Seven lions of a zoo tested positive for SARS-CoV-2 immunity, and a retrospective investigation in the same zoo confirmed the virus infection in a tiger. Human-to-animal transmission has been proposed in the tiger and lions. The finding emphasized the importance of monitoring COVID-19 exposure history in animal species through passive and active surveillance. The summary information of this dissertation contributes to public awareness, risk communication, and the understanding of SARS-CoV-2 dynamics in domestic animals and wildlife populations.

En el contexto de los procesos de vinculación tecnológica para la mejora del hábitat, la co-construcción del conocimiento y su apropiación, adquieren una relevancia fundamental. Este estudio presenta el análisis de la construcción de un edificio de la sede de la Asociación de Campesinos de Tucumán con las técnicas de tierra alivianada encofrada y revoques de tierra. El objetivo de este estudio radica en proponer una serie de categorías de implementación que permiten evaluar el nivel de asimilación (o apropiación) de las técnicas de construcción. Para ello, se obtuvo información mediante entrevistas a actores clave y encuestas a los participantes de las actividades, donde se registraron sus perspectivas sobre el proceso, el producto y las formas de organización. Se propusieron cuatro categorías para caracterizar el proceso de apropiación de las técnicas: independencia, reformulación, transmisión y apreciación técnica. Las capacitaciones de los técnicos y las realizadas internamente entre miembros de la asociación, las reformulaciones de las técnicas constructivas, y su capacidad de organización en torno a la construcción dan la pauta de un aprendizaje significativo de nuevas destrezas y asimilación de las técnicas constructivas propuestas, que retornan al equipo de investigación en la construcción de una agenda de investigación a futuro.
Deep Monte-Carlo EM for Semantic Segmentation using Weakly-and-Semi-Supervised Learning Using Very Few Expert Segmentations
Authors: Gaikwad Akshay V , Awate Suyash
Published: June 2024

Typical methods for semantic image segmentation rely on large training sets comprising per-pixel semantic segmentations. In medical-imaging applications, obtaining a large number of expert segmentations can be difficult because of the underlying demands on the experts’ time and the budget. However, in many such applications, it is much easier to obtain image-level information indicating the class labels of the objects of interest present in the image. We propose a novel deep-neural-network (DNN) framework for the semantic segmentation of images relying on weakly-and-semi-supervised learning from a training set comprising (i) very few images having per-pixel semantic segmentations and (ii) all images having class labels for the objects of interest present within. To enable weakly-and-semi-supervised learning, our framework proposes to couple the tasks of semantic segmentation and image classification, by incorporating a semantic-segmenter DNN followed by a translator DNN with end-to-end learning. We propose variational learning relying on Monte-Carlo expectation maximization, infering a posterior distribution on the hidden variable that models the segmenter-DNN’s latent space. We propose a Metropolis-Hastings sampler for the posterior distribution, along with sample reparametrizations to enable end-to-end backpropagation. Results on three publicly available real-world microscopy datasets show the benefits of our framework over existing methods, along with empirical insights into the workings of various approaches.

Published: June 2024

Pathological lymph node delineation is crucial in cancer diagnosis, progression assessment, and treatment planning. The MICCAI 2023 Lymph Node Quantification Challenge published the first public dataset for pathological lymph node segmentation in the mediastinum. As lymph node annotations are expensive, the challenge was formed as a weakly supervised learning task, where only a subset of all lymph nodes in the training set have been annotated. For the challenge submission, multiple methods for training on these weakly supervised data were explored, including noisy label training, loss masking of unlabeled data, and an approach that integrated the TotalSegmentator toolbox as a form of pseudo labeling in order to reduce the number of unknown voxels. Furthermore, multiple public TCIA datasets were incorporated into the training to improve the performance of the deep learning model. Our submitted model achieved a Dice score of 0.628 and an average symmetric surface distance of 5.8~mm on the challenge test set. With our submitted model, we accomplished the third rank in the MICCAI2023 LNQ challenge. A finding of our analysis was that the integration of all visible, including non-pathological lymph nodes improved the overall segmentation performance on pathological lymph nodes of the test set. Furthermore, segmentation models trained only on clinically enlarged lymph nodes, as given in the challenge scenario, could not generalize to smaller pathological lymph nodes. The code and model for the challenge submission are available at https://gitlab.lrz.de/compai/MediastinalLymphNodeSegmentation

Background/Aims: Advanced pancreatic and biliary tract cancers can invade the duodenum and cause duodenal hemorrhagic stenosis. This study aimed to evaluate the efficacy of covered self-expandable metal stents in the treatment of cancer-related duodenal hemorrhage with stenosis.Methods: Between January 2014 and December 2016, metal stents were placed in 51 patients with duodenal stenosis. Among these patients, a self-expandable covered metal stent was endoscopically placed in 10 patients with hemorrhagic duodenal stenosis caused by pancreatobiliary cancer progression. We retrospectively analyzed the therapeutic efficacy of the stents by evaluating the technical and clinical success rates based on successful stent placement, degree of oral intake, hemostasis, stent patency, and overall survival.Results: The technical and clinical success rates were 100%. All 10 patients achieved a gastric outlet obstruction scoring system score of three within two weeks after the procedure and had no recurrence of melena. The median stent patency duration and overall survival after stent placement were 52 days (range, 20–220 days) and 66.5 days (range, 31–220 days), respectively.Conclusions: Endoscopic placement of a covered metal stent for hemorrhagic duodenal stenosis associated with pancreatic or biliary tract cancer resulted in duodenal hemostasis, recanalization, and improved quality of life.

Published: June 2024

The Italian language and Italian culture have left lasting and profound marks on the languages and cultures of most European countries, including Bulgaria. In many cases, however, we do not see the aspects of this influence and do not know the factors that have led to it. This text examines the main areas of use in which words of Italian origin have a significant presence. We have tried to indicate the historical preconditions and circumstances that lead to the Italian language becoming established in certain thematic areas. We have cited as an example a number of lexical units, some of which are part of everyday Bulgarian, while others are highly specialized terms used by experts in the given field.

МНОГОГРАННОСТЬ КОНЦЕПЦИИ «ИНКЛЮЗИВНЫЙ ТУРИЗМ»
Authors: Азимова Шахло
Published: June 2024

«Инклюзивный туризм» является ключевым понятием в современных дискуссиях, но его часто недостаточно ясно интерпретируют, в частности из-за его связи с различными родственными терминами в сфере. В силу своей многогранности концепция инклюзивного туризма возникает в рамках более широкого спектра пересекающихся концепций, направленных на улучшение как самой индустрии туризма, так и её воздействия на опыт путешественников посредством предоставления универсальных туристических продуктов, услуг и среды для участия в туристическом опыте. Однако, несмотря на данную перспективу, концептуализация термина остается неясной. Проблема отсутствия четкого определения термина «инклюзивный туризм» отчасти связана с тенденцией рассматривать синонимичные термины в сфере туризма, как взаимозаменяемые, уделяя основное внимание обеспечению доступа для лиц с инвалидностью к туристическим продуктам и услугам

Antropofagia, tempo e dívida
Authors: Gorni Bittencourt Ana Paula
Published: June 2024

Este artigo aborda a relação entre a dívida e a temporalidade no pensamento de Oswald de Andrade a partir da interlocução do pensamento do autor com a obra de Nietzsche, especialmente a Segunda Dissertação da Genealogia da Moral. Para isso, serão discutidos alguns aspectos do papel da relação credor-devedor na ascensão da má-consciência na perspectiva nietzscheana, processo que possui convergências com o que Oswald de Andrade denominou de “queda”, ou passagem do Matriarcado ao Patriarcado. Um dos objetivos deste trabalho é, portanto, elucidar a relação espaço-temporal como critério da classificação cultural oswaldiana entre matriarcado e patriarcado, considerando que o modo como essa relação é estabelecida passa pela relação credor-devedor. O patriarcado, que é caracterizado pela cultura messiânica e individualista, é definido como expressão social do ser humano em seu estado de negatividade. A negatividade do ser humano é, para Oswald de Andrade, a quarta dimensão do cosmos: o próprio tempo.  Também corresponde à quarta dimensão uma propriedade devorativa restritiva que se opõe à propriedade devorativa da dimensão positiva, que é a dimensão espacial. Ao contrário da devoração negativa, a antropofagia (ou devoração positiva) teria a propriedade de transformar permanentemente o tabu em totem- o negativo em positivo.  Como contraponto ao desvio do sentido da dívida que configura o patriarcado, é possível identificar o ócio, a arte e o vínculo com a terra.

Hoy en día el trabajo artesanal se enfrenta a desafíos de calidad y productividad; el hablar de innovación es hablar de la conceptualización de ideas a partir de la propuesta de solución de problemas, más aún, el hablar de patentamientos para la solución de problemas en el sector artesanal pudiera ser paradójico. En  las comunidades del norte del estado de Veracruz, en la región conocida como Huasteca Alta, existen comunidades indígenas que realizan diversas actividades tipo artesanal, desde la elaboración de pan, licor de miel y diversos artículos como morrales, tapetes, petates, entre otras artesanías que son hechas de palma, zapupe y piel; sin embargo, en el proceso de elaboración de las mismas, existen problemáticas de tipo ergonómico, social y con relación a la productividad; es por ello que  partir de esa premisa, surge la necesidad de aplicar herramientas de ingeniería industrial y principios mejora de procesos e innovación para lograr la conceptualización, el diseño de herramientas o prototipos  diseñados para cubrir las necesidad del entorno y obtener mejoras en los procesos antes mencionados. El objetivo de este trabajo es mostrar la importancia del papel de la mujer en la ingeniería y la optimización de procesos y la mejora continua, ya que estos trabajos de diseño y conceptualización han sido liderados por un grupo de ingenieras industriales especialistas en diseño e innovación, manufactura y propiedad industrial, logrando modelos de utilidad y registros de software ante e IMPI e INDAUTOR.

Published: June 2024

1980’li yıllarla beraber popüler olan ve günümüze dek dönem dönem öne çıkan mali sürdürülebilirlik kavramı, günümüzün artan kriz ve konjonktürel dalgalanmalarının da etkisiyle tekrar gündeme gelmiştir. Ekonomik istikrarın tesisinde olmazsa olmazlar arasında yer alan mali sürdürülebilirlik kavramı, tüm ekonomiler açısından olduğu gibi bu çalışmanın ampirik analizinin yatay kesitini oluşturan ülke grubu, Kırılgan Beşliler içinde büyük önem taşımaktadır. 2008 küresel finans krizi ve 2019 yılında baş gösteren COVID 19 Pandemisi, diğer ülke ya da ülke gruplarında olduğu gibi Kırılgan Beşli olarak adlandırılan ülkeleri de önemli ölçüde etkilemiştir. Ülkeler yaşanan bu iki olumsuz gelişmenin yarattığı derin ekonomik krizin olumsuz etkilerini bertaraf etmek amacıyla, para politikası uygulamalarının yanı sıra maliye politikası araçlarını da etkin bir biçimde kullanmışlardır. Bu çalışmada, yabancı yatırımlara olan gereksinimleri yüksek, dışsal mali şoklardan önemli ölçüde etkilenen, derinleşen dış borç yükleri ile yüksek bütçe ve cari denge açıklarına sahip, Amerikan yatırım bankalarından Morgan Stanley’in 2013’de yayınladığı raporda dile getirilen Brezilya, Endonezya, Güney Afrika, Hindistan ve Türkiye’nin oluşturduğu Kırılgan Beşli ülke grubunun, 2000 ve 2022 yılları arası döneme ait yıllık verileri kullanılarak (2 model aracılığıyla) mali sürdürülebilirlikleri araştırılmaktadır. Çalışmanın ampirik kısmında panel regresyon analizi gerçekleştirilmiş ve yapılan tahminlerin değişen varyans ve otokorelasyon problemine karşı dirençli olmalarına özen gösterilmiştir. Ulaşılan sonuçlara göre, model 1’de yer alan değişkenlerden kamu gelir ve harcamaları açısından Kırılgan Beşli ülkelerinde mali sürdürülebilirliğin zayıf olduğu, model 2’de kullanılan değişkenlerden birincil bütçe dengesi ve kamu borç stokunun milli gelir içerisindeki payı arasındaki ilişki açısından ise mali sürdürülebilirliğin olmadığı sonucu elde edilmiştir.

Dünya küreselleşmeyle birlikte birçok alanda dönüşüm sürecine girmiştir. Bilişim teknolojilerinde küreselleşmeyle başlayan gelişmeler beraberinde bu teknolojileri kullanan kamu kurumlarını da etkilemiş; başta e-devlet kavramı ve bu kavramın yerel yönetimlere yansıması olan e-belediyecilik kavramlarının oluşmasını sağlamıştır. E-belediyecilik kavramının yerel yönetimlerden büyükşehir belediyelerine doğru uyarlanıp uyarlanmadığını, yalnızca bilgi verme ya da yerel yönetimlerin tanıtımının mı yapıldığı yoksa asıl amacına uygun olarak vatandaşın faydalanmak istediği hizmeti en doğru şekilde sunmak mı olduğunu tespit etmek maksadıyla büyükşehir belediyelerinin bu konudaki yeterlilik düzeyleri içerik analizi tekniğiyle incelenmiştir. Bu çalışmada Türkiye’de bulunan 30 büyükşehir belediyesinin web siteleri 4 ana ölçüt ve bu ölçütlere bağlı 50 alt ölçütlere göre analiz edilip büyükşehir belediyelerinin e-belediyecilik kapsamında yeterlilik düzeylerinin belirlenmesi amaçlanmaktadır. Çalışma sonunda elde edilen verilere bakıldığında e-belediyecilik konusunda büyükşehir belediyelerin son zamanlarda oluşturdukları web sitelerinin genelinin yeterli düzeyde olduğu ve eksikliklerin olduğu konularda da büyükşehir belediyelerine önerilerde bulunulmuştur.

Stimulating the growth and development of toddlers is a very important thing given by parents. If stimulation is inadequate, the growth and development of toddlers will be disrupted. However, in reality there are still many parents who do not understand the importance of screening and stimulating growth and development in children. Screening is carried out to detect irregularities early so that it will be easier to overcome them. One of the efforts to overcome this is by educating parents about stimulating growth and development using the KPSP format. KPSP is a tool/instrument used to determine whether a child's development is normal or whether there are deviations. The aim of this community service is to socialize monitoring of children's growth and development using KPSP among parents. The method used in this community service activity is active and participatory learning through several stages, namely the preparation stage, implementation stage and evaluation stage with a total of 20 parents participating. The results obtained were an increase in parental knowledge, in this case mothers, after being given education about monitoring children's growth and development using the Pre-Developmental Screening Questionnaire (KPSP). It is recommended that health workers need follow-up action from the Community Health Center so that they can facilitate supporting facilities for parents to independently screen their child's development.
