▼ Utilization of polarized light for improved specificity and sensitivity in disease diagnosis is occurring more often in fields of sensing, measurement, and medical diagnostics. This dissertation focuses on two distinct areas where polarized light is applied in biomedical sensing/monitoring: The first portion of worked reported in this dissertation focuses on addressing several major obstacles that exist prohibiting the use of polarized light as a means of developing an optical based non-invasive polarimetric glucose sensor to improve the quality of life and disease monitoring for millions of people currently afflicted by diabetes mellitus. In this work there are two key areas, which were focused on that require further technical advances for the technology to be realized as a viable solution. First, in vivo studies performed on New Zealand White (NZW) rabbits using a dual-wavelength polarimeter were conducted to allow for performance validation and modeling for predictive glucose measurements accounting for the time delay associated with blood aqueous humor glucose concentrations in addition to overcoming motion induced birefringence utilizing multiple linear regression analysis. Further, feasibility of non-matched index of refraction eye coupling between the system and corneal surface was evaluated using modeling and verified with in vitro testing validation. The system was initially modeled followed by construction of the non-matched coupling configuration for testing in vitro. The second half of the dissertation focuses on the use of polarized light microscopy designed, built, and tested as a low-cost high quality cellphone based polarimetric imaging system to aid medical health professionals in improved diagnosis of disease in the clinic and in low-resource settings. Malaria remains a major global health burden and new methods for, low-cost, high-sensitivity diagnosis of malaria are needed particularly in remote low-resource areas throughout the world. Here, a cost effective optical cell-phone based transmission polarized light microscope system is presented utilized for imaging the malaria pigment known as hemozoin. Validation testing of the optical resolution required to provide diagnosis similar to commercial polarized imaging systems will be conducted and the optimal design will be utilized in addition to image processing to improve the diagnostic capability.

O principal efeito da microabrasão no esmalte dental é uma erosão significativa. Porém, existe uma lacuna na literatura no que concerne à avaliação validada e reprodutível da profundidade de desgaste na superfície dental natural. OBJETIVOS: Avaliar a profundidade de desgaste e a perda mineral do esmalte dentário resultante da técnica de microabrasão na superfície coronária original de dentes humanos. MATERIAIS E MÉTODOS: 40 terceiros molares humanos extraídos foram divididos aleatoriamente em 4 grupos, de 10 espécimes cada, de acordo com o material microabrasivo utilizado: AC - ácido clorídrico a 18% e pedra-pomes, AF - ácido fosfórico a 37% e pedra-pomes, OP - Opalustre e WRM - Whiteness RM. Cada elemento teve as laterais da face vestibular protegidas para que apenas a área central fosse exposta aos agentes microabrasivos. Após o procedimento de microabrasão, cortes transversais não desmineralizados foram preparados e submetidos à radiomicrografia e análise em Microscopia de Luz Polarizada. Uma terminologia própria foi formulada para a morfologia da interface esmalte normalmicroabrasionado. Esta serviu de base à introdução de uma Técnica de Perfilometria com Análise de Imagens Digitais, com o intuito de obter a profundidade de desgaste ao longo da área microabrasionada. O teste de correlação intraclasse foi aplicado para testar a reprodutibilidade da técnica. A quantidade da perda mineral e a profundidade em que esta ocorreu foram analisadas em transversais traçadas em pontos eqüidistantes do limite esmalte normal-microabrasionado. Os dados obtidos foram analisados com o teste ANOVA (p <0,05). RESULTADOS: A Técnica de Perfilometria obteve uma boa reprodutibilidade (coeficiente de correlação intraclasse de 0,9998) e foi validada internamente. O grupo AC foi o mais agressivo, apresentando a maior profundidade de desgaste (110,51 41,21 μm), e a maior perda mineral (13 3 peso %), com diferenças significantes em relação aos grupos WRM (p <0,05; 9,41 4,4 peso %) e OP (p <0,05; 9,0 3,8 peso %). O grupo OP, por outro lado, foi o menos agressivo com os menores valores para todos os parâmetros analisados, apresentando uma profundidade de desgaste menor em relação aos grupos AC (p <0,0001), WRM (p <0,001; 86,24 27,99 μm) e AF (p <0,05; 74,46 42,06 μm). Os outros dois grupos apresentaram resultados intermediários para profundidade de desgaste e quantidade de perda mineral. Não houve diferença quanto à profundidade de perda mineral CONCLUSÃO: Com base em uma terminologia própria para a interface esmalte normal-microabrasionado e na aplicação de uma nova Técnica de Perfilometria, os agentes testados mostraram uma significativa diferença quanto à profundidade de desgaste, que foi condizente com a perda mineral. A nova Técnica de Perfilometria propõe o preenchimento de uma lacuna na literatura, permitindo a determinação física de profundidade de desgaste em superfícies naturalmente curvas de tecidos biológicos duros.

▼ The synthesis of biomimetic hydroxyapatite-collagen composites is desirable from the perspective of graft elimination and load-bearing support when treating damaged or diseased bone. Bone is an organized network of carbonated hydroxyapatite mineralized collagen, whose strength and toughness is dependent on the organized array of mineralized collagen fibers that align with applied physiologic stresses. The apatitic calcium phosphate phase, hydroxyapatite, is promising for the biomimetic mineralization of collagen. Hydroxyapatite-collagen composites are osteoconductive and resorbable. However, the mechanical properties of these composites are one or more orders of magnitude less than bone. The aim of this study was to produce a bone-like hydroxyapatite-collagen composite with an induced collagen fiber alignment in order to improve the mechanical properties of the composite. In this study, environmental and temporal effects on the synthesis of a hydroxyapatite-collagen composite were characterized and compared to bone. Three dimensional hydroxyapatite-collagen composite scaffolds were fabricated by a combined extrusion and compaction process producing three different levels of collagen fiber alignment, which were quantified and correlated to the resultant mechanical properties. The levels of collagen fiber alignment corresponded to an expected random alignment, low longitudinal alignment, and high longitudinal alignment. The results showed that a bone-like hydroxyapatite-collagen composite is best synthesized in physiologic to alkaline pH (7.4 - 8.0) and allowed to react for 6 hours. Composite scaffolds fabricated with the low longitudinal alignment method produced the highest degree of alignment among the fabrication methods. Degree of collagen alignment produced the best strain and toughness responses. Compaction aided strength related mechanical properties. This study gives proof of concept for a collagen fiber alignment process and indicates that the mechanical properties of a three dimensional HAp/C composite scaffold fabricated by this process are dependent on the degree of collagen fiber alignment.

Visando compreender como se comporta a organização das fibras colágenas do estroma corneal de cães por meio de propriedades birrefringentes, objetivou–se com a pesquisa mapear a supraorganização das fibras do estroma corneal de cães, de maneira setorizada e comparativa, nos diferentes sítios e fragmentos. Córneas (n=22) foram removidas de 11 cães submetidos a eutanásia por razões não relacionadas à pesquisa. Quatro córneas foram estudadas in totum, após confecção de montagens totais, e 18 foram incluídas em parafina e transversalmente seccionadas para 7 µm. Todo o material foi estudado sob microscópio de luz polarizada (Olympus BX-53 Pol, Tóquio, Japão) munido de luz policromática e monocromática de 546 nm, compensadores de Sénarmont e Brace-Köhler, e sistema para vídeo-análise de imagens. As fibras colágenas foram posicionadas a 45 e 90 graus do plano da luz polarizada (PLP) e avaliadas setorialmente, ou seja, nas regiões anterior, média e profunda dos estromas superior, inferior, central, nasal e temporal das córneas. A supraorganização das fibras colágenas foi estabelecida a partir dos valores da diferença do caminho óptico (OPD) quantificados pelo método de Sénarmont e Brace-Köhler. O tensor de estrutura, foi processado com auxílio do plugin Java “OrientationJ”. Diferenças com P<0,05 foram consideradas significativas. Não foram observadas diferenças em alinhamento das fibras colágenas entre as regiões superior, inferior e central da córnea (P>0,05). As fibras colágenas nos sítios anterior e médio dos fragmentos nasal e temporal das córneas foram menos alinhadas e mais onduladas do que as fibras colágenas dos demais fragmentos corneais (P<0,05). As fibras colágenas dos fragmentos centrais das córneas apresentaram valores altos de OPD, ou seja, foram mais compactadas, se comparadas com as fibras das outras regiões da córnea (P<0,01). Em contraste, as fibras do fragmento inferior foram menos compactadas (valores<OPD) do que nos outros fragmentos (P<0,01). As fibras colágenas estromais da córnea canina apresentam birrefringência de forma (BF) positiva. A contribuição da BF para a Birrefringência total (BT) foi superior a 80%. Relativamente a birrefringência intrínseca (BI), fibras colágenas nos fragmentos corneais central e inferior apresentaram, respectivamente, o menor e o maior valor. Em…

The transeptal fibers are located in the lamina propria of the gingiva between adjacent teeth. They are often described as a group of collagen fibers embedded in the cementum of one tooth that follows a straight path over the alveolar bone crest and embeds itself in the cementum of the adjacent tooth. In a distinct way, it was reported in the literature that the transeptal fibers are not continuous over its full length but originates from the adjacent teeth interlacing in the central area of the interproximal gingiva. The present study aimed to evaluate and quantitate the gingival transseptal fibers arrangement by histomorphometry and histochemistry of sagittally cut tissue sections of the interdental region between first and second maxilar molar teeth of 12 male Wistar rat. The collagen fibers were stained with Picrosirius red staining and assessed with linear polarized light microscopy, digital image processing and analysis based on Fourier transform measurements and filtering techniques. Histomorphometrical parameters like fiber orientation, area fraction and fractal dimension were measured. The maximal brilliance presented by the fibers was evaluated using intensity histogram measurements. These quantitative parameters were compared among three different regions of interest along the length of the interdental gingiva using one-way analysis of variance (ANOVA) and Bonferronis or Tamhanes T2 post hoc tests. There was an increase (p <0.05) in area fraction and fractal dimension parameters in the central region compared to regions near the teeth, and no difference in the orientation and maximal brilliance of fibers among the tree regions. Our results quantitative demonstrated a denser arrangement of the fibers in the central region reinforcing the model of an interlacement of the transseptal fibers in that region

As fibras transeptais situam-se na lâmina própria da gengiva entre dois dentes adjacentes. São comumente descritas como um grupo de fibras colágenas inseridas no cemento de um dente que seguem diretamente por sobre a crista óssea alveolar inserindo-se em uma região correspondente no cemento do dente adjacente. De maneira distinta, relatou-se na literatura que as fibras transeptais não são contínuas ao longo de toda sua extensão; são originadas dos dentes adjacentes, entrelaçando-se na região central do espaço interproximal. Com o presente estudo, objetivou-se avaliar e quantificar o arranjo das fibras gengivais transeptais empregando-se análise histomorfométrica e histoquímica em cortes histológicos sagitais da região entre primeiro e segundo molares da maxila de 12 ratos Wistar machos. As fibras colágenas foram coradas pelo método de picro-sirius e analisadas por microscopia de luz polarizada linear, processamento e análise digital de imagem baseados em métodos de filtragem e medição por transformada de Fourier. Foram realizadas medidas histomorfométricas de orientação, densidade e dimensão fractal das fibras. O brilho máximo apresentado pelas fibras foi mensurado pelo histograma de intensidade. Os…

▼ Aims: The aims of this study were to test the hypothesis that PS-OCT can be used to nondestructively measure and quantify the severity of the early demineralization of buccal and occlusal enamel surfaces and assess the effect of fluoride varnish in inhibiting demineralization in vivo.Material & Methods: Twenty subjects requiring bilateral premolar extractions were used. A cariogenic challenge was introduced by cementing orthodontic bands with a buccal window to these premolars and by making incisions on their occlusal surface. Bands were removed after 30 days and PS-OCT scans were acquired in vivo of occlusal and buccal areas. A split mouth design was used to test the effects of fluoride varnish. Teeth were extracted, serial sectioned and analyzed using Polarized Light Microscopy and Microradiography for comparison with the PS-OCT images.Results: High quality PS-OCT images were acquired in vivo, with excellent optical penetration through the sound enamel to the dentin. Both occlusal and buccal surfaces showed a significant difference between the "sound" and "carious" enamel groups. The "sound" group had an average ΔR = 67.72 dB * μm, and the "carious" group had an average ΔR = 206.64 dB * μm. Both PLM and PS-OCT lesion depth measurements showed a significant difference between the "sound" and "carious" enamel groups for the occlusal surface, but not for the buccal surface, when calculated with PS-OCT. There was not a significant difference between the fluoride varnish and control groups in both TMR and PS-OCT tests.Conclusion: This is the first clinical study to show the great potential of PS-OCT as a clinical tool, to nondestructively measure the depth and severity of early enamel demineralization including the high risk areas of occlusal surfaces and around orthodontic appliances, and to assess the efficacy of chemical intervention. With further studies, PS-OCT can prove to be valuable in the clinical setting due to its: ease of use, high contrast of early detection compared to traditional x rays or visual evaluation, and value of early detection in taking preventive action.

L’architecture des cellules myocardiques en trois dimensions du cœur normal et malformé est un sujet de recherche initié depuis plusieurs siècles, mais il existe encore des questions non résolues. Cette thèse apporte de nouveaux éléments de réponse grâce à l'utilisation d'une technique originale d'Imagerie en Lumière Polarisée et l'étude d'une période précise du développement des tissus cardiaques, celle de l'adaptation postnatale. Dans cette thèse, nous introduisons deux nouvelles représentations de l'information : un paramètre d'Isotropie régional et la dissection virtuelle à la base de représentation en LIC-3D qui permet l'exploration à volonté des masse ventriculaires selon des angles de coupes arbitraires.Le remodelage ventriculaire physiologique postnatal (étudié sur 16 cœurs) s'accompagne globalement d'une diminution de l'isotropie régionale et localement par l'apparition de zones fortement isotropes dont la topologie est identique aux plans de clivage décrits dans le modèle de Torrent - Guasp. Cette étude apporte pour la première fois des éléments complémentaires pour la description des composantes profondes de la voie de sortie du ventricule droit. L'architecture 3D du septum de sortie, du repli ventriculo-infundibulaire et des « fibres » latitudinales de la paroi de deux ventricules est documentée et précisée dans dix cœurs normaux. Dans une étude de 11 cœurs malformés représentant 7 pathologies différentes, 3 patrons topologiques ont été décrits : 1) le patron normal : Alignement du repli ventriculo-infundibulaire et du septum de sortie, dans les malformations de type de communication interventriculaire ou canal atrio-ventriculaire ; 2) le patron parallèle : le repli ventriculo-infundibulaire et septum de sortie sont parallèles dans la Tétralogie de Fallot ; 3) le patron en V : le repli ventriculo-infundibulaire dans les cœurs avec discontinuité musculaire mitro-artérielle.En conclusion, nous apportons des nouveaux éléments de compréhension de la mise en place de l'architecture du myocarde en situation normale et pathologique. Cependant, ces données nouvelles devront être consolidées statistiquement sur un plus grand nombre de cas. Elle devront être confrontées aux données physiologiques observables grâce au méthodes d'imagerie fonctionnelle.

The 3D architecture of the ventricular mass is poorly known, although in vivo imaging techniques show the physiological inhomogeneity of transmural myocardial mechanics. Polarized light imaging makes it possible to quantitatively analyse the myocardial cell orientation to study the regional isotropy of myosin filaments (a new parameter) and to provide virtual dissection (a new tool) of the myocardial ventricular mesh. This deep inside is complementary of superficial anatomical description.Sixteen normal hearts of human term stillbirths, newborns and infants were studied. During the first months of postnatal age, the median regional isotropy values decreased in the ventricular three-dimensional mesh. There was a progressive appearance of a particularly inhomogeneous…

▼ This dissertation thesis concerns with Analysis of Influence of Collagen Organization on Mechanical Properties of Arteries and it is divided into three main parts. Motivation for this dissertation thesis was in a study reviewing effect of material model upon resulting stresses in AAA. The effect was calculated in 70 patient-specific geometries of AAA, which exceeds the number of geometries in other scientific papers by one order. Within this study, two material models were used, i.e. real one and 100× stiffer, and obtained stresses were mutually compared. It was quantified that peak stress difference can be higher than 20 % in 10% of patients and therefore the real material model should be preferred over the artificial one although operation with this model is more demanding. The second part of this thesis deals with an identification of structural parameters (orientation and dispersion of collagen fibres) of porcine aortic tissue by using adjusted Fast Fourier Transform based algorithm. The extracted structural parameters were inserted into two-layer structure-motivated constitutive model Martufi-Gasser. This model was validated and its predictive capabilities were also tested with fine results. The most important information obtained from the digital image processing of ~9000 micrographs is existence of only one family of dispersed collagen fibres which breaks the current dogma present in many scientific papers about two families of collagen fibres. The third part concerns with a proposal of an automated phase-correlation based algorithm for obtaining collagen fibre direction from polarized light microscopy images. The proposed algorithm was verified and validated and it yields histograms of collagen fibre directions with overall number of measured points larger than it would be possible to get from any manual measurement. The limitation of the original proposed algorithm is in 90° period of polarized light intensity, thus the method results in angles in the range of 0°–90. Therefore the end of the thesis is dedicated resolving this problem and obtaining real angles in a span of 0°–180°. To this end, the microscope set-up was changed and the algorithm was adjusted accordingly. The original and the adjusted algorithms are collagen-specific, fast and an operator independent. Despite all the author´s effort put into collagen fibre waviness quantification directly from the histograms, the waviness has not been quantified yet in this way and it remains at the stage of research.

Measurements on coccolith abundance and mass can be used as a signal of primary productivity and pelagic calcification in response to environmental change. The Leeuwin Current (LC) is known to transport warm and low-salinity waters from the Indo-Pacific Warm Pool (IPWP) southwards along the coast of West Australia. Along with the onset of continental aridity during late Neogene, increased strength of the LC may have played a role in reef expansion on the Northwest Shelf. In this study the morphological variation in size and mass of reticulofenestrid coccoliths was assessed in material from IODP Site U1461 in the eastern Indian Ocean spanning the past 500 ka. Both the absolute abundance of all reticulofenstrid coccoliths (Emiliania huxleyi, Reticulofenestra spp., Gephyrocapsa spp. and Pseudoemiliania spp.) was determined, as well as the relative abundance of large versus small coccoliths. Coccolith size and mass were measured quantitatively under circularly polarized light. The data was compared to variations in sea surface temperatures (SST) of the LC, and to continental aridity of Australia. SST fluctuations could influence coccolithophore productivity by affecting their metabolic rate, whereas continental aridity may influence the influx of terrestrial matter by wind. The investigated interval is dominated by small species of Gephyrocapsa. Peak values of absolute abundance and mass were observed during Marine Isotope Stage (MIS) 11, an interglacial period of extended warmth and humidity. These results coupled with high densities of aragonite needles in the same samples indicate the sediments were diluted by material overflowing from the adjacent shallow- water carbonate platform, analogous to the whiting events observed in the modern-day Bahamas. A decrease in abundance of Gephyrocapsa caribbeanica at 240 ka can be linked to the timing of their last common occurrence (LCO), within MIS 7. The subsequent shift to Gephyrocapsa oceanica as the dominant large species may indicate an ecological replacement of G. caribbeanica, or signify warm and low-salinity waters.

▼ Objectives: The aim of this in vitro study was to assess the effect of toothpastes containing three different sodium fluoride concentrations and a calcium sodium phosphosilicate system on root dentin demineralization and remineralization. Methods: Pre softened bovine root dentin specimens followed two major experimental directions namely the protocols A and Β. During protocols A and Β the slabs were subjected to a ten and to a fourteen day pH cycling procedure respectively simulating low and high in vivo caries experience respectively. The slabs were immersed twice daily either after the demineralization periods (protocol A) or before and after the demineralization period (protocol B) for 2mm in the following toothpaste slurries (a) non fluoridated (control), (b) 7.5% calcium sodium phosphosilicate, (c) 1450ppm F, (d) 2800ppm F and (e) 5000ppm F. Subsequently the specimens were subjected to a 15 h (protocol A) and to a 50 h (protocol B) acid resistance test. In protocol A surface KHN was assessed initially and during the pH cycling and the acid resistance test period. Repeated measurements in each group were analyzed through appropriate regression models for longitudinal data. In protocol Β KHN microhardness measurements were carried out in specimens cross sections and comparisons between the toothpaste groups were performed through ANOVA based tests and by regression analysis of the derived statistic of integrated vol% mineral loss. Also lesions were evaluated qualitatively using transmission and polarized light microscopy. Results: In low canogenic conditions all fluoride groups during pH cycling showed significantly less surface microhardness loss and subsequently exhibited increased acid resistance compared to the control. The 5000ppm F and 2800ppm F toothpastes inhibited demineralization significantly more effectively than the 1450ppm F and the calcium sodium phosphosihcate toothpaste while no significant differences were found between the two high fluoride groups. The calcium sodium phosphosilicate group during pH cycling performed marginally superior compared to control (p=0 079) but its acid resistance behavior was similar to control’s. In high canogenic environment the 5000ppm F group during pH cycling presented significantly less total vol% mineral loss and subsequently exhibited considerably increased surface acid resistance compared to all the other tested groups. The calcium sodium phosphosilicate group during pH cycling presented significantly less microhardness loss of the surface layers than the control nevertheless subsequently the acid resistance of the calcium sodium phosphosilicate group was similar to that of the control group. These observations were confirmed by microscopic examination of the lesions. Conclusions: Under the present experimental conditions in low canogenic environment 5000ppm F and 2800ppm F toothpastes promoted remineralization and/or inhibited demineralization more effectively than the other tested toothpastes whereas in high canogenic environment the 5000ppm F toothpaste…

O objetivo do presente trabalho é classificar pixels co-registrados de pilhas de imagens de luz polarizada de minério de ferro nos seus respectivos grãos cristalinos ou poros, produzindo assim imagens segmentadas por grãos que podem ser analisados quanto às suas distribuições de tamanho, forma e orientação, bem como sua porosidade, tamanho e forma dos poros. Seções polidas de amostras de minério de ferro rico em hematita foram imageadas difratalmente em um microscópio com polarizador giratório em ângulos variados de polarização. Uma pilha de imagens foi produzida para cada campo na qual cada imagem corresponde a uma orientação do polarizador. Cada ponto na amostra foi registrado nas mesmas coordenadas em todas as imagens da pilha. O conjunto resultante de intensidades de cada pixel está diretamente relacionado com a orientação do cristal amostrado na posição correspondente. A análise multivariada dos conjuntos de intensidades leva à classificação dos pixels nos seus respectivos grãos cristalinos. Grãos individuais de hematita do minério de ferro, bem como os seus poros foram segmentados. Os resultados foram comparados com aqueles obtidos pelo método de contagem dos pontos, ou seja, por inspeção visual.

The aim of the present work is to classify co-registered pixels of stacks of polarized light images of iron ore into their respective crystalline grains or pores, thus producing grain segmented images that can be analyzed by their size, shape and orientation distributions, as well as their porosity and the size and morphology of the pores. Polished sections of samples of hematite-rich ore are digitally imaged in a rotating polarizer microscope at varying planepolarization angles. An image stack is produced for every field of view, where each image corresponds to a polarizer position. Any point in the sample is registered to the same pixel coordinates at all images in the stack. The resulting set of intensities for each pixel is directly related to the orientation of the crystal sampled at the corresponding position. Multivariate analysis of the sets of intensities leads to the classification of the pixels into their respective crystalline grains. Individual hematite grains of iron ore, as well as their pores, are segmented. The results are compared to those obtained by visual point counting methods.

▼ Introdução: O fuso meiótico dos oócitos de mamíferos pode se despolimerizar quando exposto a pequenas variações de temperatura. Este fato já está bem estabelecido e estudado em oócitos maduros em metáfase II (MII). No entanto, pouco se sabe a respeito da influência da diminuição da temperatura sobre o fuso meiótico dos oócitos imaturos. Desse modo, este estudo tem como objetivos: 1) avaliar a influência da diminuição da temperatura sobre o fuso meiótico de oócitos de camundongas maturados in vitro e 2) avaliar o fuso meiótico em oócitos humanos maturados in vitro submetidos à criopreservação pela técnica de congelação lenta ou por vitrificação quando em estágio de vesícula germinativa. Métodos: Realizaram-se dois experimentos, denominados 1 e 2, sendo o primeiro em oócitos de camundongas e o segundo em oócitos humanos. No experimento 1 oócitos imaturos de camundongas nos estágios de metáfase I (MI), telófase I(TI) e MII foram cultivados nas seguintes temperaturas: 37º C (controle), temperatura ambiente (22 °C) e 4º C por 0, 10, 30 e 60 minutos. Após este período de tempo o fuso meiótico oocitário foi avaliado por meio de microscopia de luz polarizada (MLP) (LC-Polscope-Oosight image software) e imunocitoquímica (IC). No experimento 2 oócitos em estágio de vesícula germinativa (GV) coletados de pacientes submetidas à indução da ovulação e fertilização in vitro, foram divididos de forma randômica em três grupos: oócitos a fresco (A), oócitos congelados pela técnica de congelação lenta (B) e oócitos congelados pela técnica de vitrificação (C). Os oócitos a fresco, os descongelados e os aquecidos foram maturados in vitro até estágio de (MII). A análise do fuso meiótico foi realizada por microscópio invertido equipado com uma câmera de vídeo analógica e um sistema de imagens que combina luz polarizada em cristal líquido (ICSI Guard Octax). Resultados: Experimento 1: No tempo 0 e à 37º C, todos os oócitos apresentavam o fuso meiótico visível tanto pela MLP quanto pela IC. À 4º C, o número de oócitos em MI com fuso meiótico visível por meio da MLP foi menor do que com a IC, e descresceu com o tempo, fato que também ocorreu, em menor proporção, com os oócitos em TI. No entanto, a 4º C, o reconhecimento do fuso meiótico dos oócitos em TI foi semelhante tanto para MLP como para IC. Quando os oócitos MII foram expostos à 4º C, a detecção do fuso meiótico teve descréscimo diretamente proporcional ao tempo de cultura quando foi utilizada a MLP, sendo que o mesmo ocorreu para a IC, porém de forma menos pronunciada. À temperatura ambiente houve um pequeno descéscimo na visualização do fuso meiótico tanto por MLP quanto por IC, porém este não foi estatisticamente significativo para os oócitos em TI. Experimento 2: A taxa de sobrevivência imediatamente após o descongelamento/ aquecimento foi de 44,6% para o grupo B e de 79% para o grupo C. Após 24 horas em cultura , estas taxas passaram para 29,2% e 69%, respectivamente. A mediana de tempo para maturação foi de 26 horas para os grupos A e C, e de 27 horas para o grupo B.

▼ Eräs keino parantaa huonosti veteen liukenevan lääkeaineen vesiliukoisuutta on valmistaa siitä ja yhdestä tai useammasta kantajapolymeeristä amorfinen kiinteä dispersio. Amorfiset kiinteät dispersiot ovat kuitenkin usein epästabiileja. Stabiilius ja lääkeaineen amorfisoituminen riippuvat esim. dispersion komponenttien sekoittuvuudesta. Lisäksi alkuvaiheen lääkekehityksessä lääkeainetta ja analyysiaikaa on rajoitetusti. Tässä työssä ensisijaisena tavoitteena oli kehittää amorfisen dispersion valmistamiseksi (liuotinmenetelmä) ja analysoimiseksi (MTDSC, moduloidun lämpötilan erotteleva pyyhkäisykalorimetri) nämä kaksi vaihetta yhdistävä menetelmä. Menetelmäkehitysosassa tutkittiin myös MTDSC-menetelmän analyysiparametrien vaihtelun mahdollisia vaikutuksia saataviin tuloksiin. Kehitetyllä menetelmällä valmistettiin ja analysoitiin amorfisia kiinteitä dispersioita, jotka koostuivat huonosti veteen liukenevasta itrakonatsolista sekä hydroksipropyylimetyyliselluloosa asetaatti sukkinaatista (HPMC-AS) ja/tai polyvinyylipyrrolidonista (PVP K30). Tulosten tulkinnan helpottamiseksi ja kehitetyn menetelmän toimivuuden varmistamiseksi dispersioita tutkittiin myös röntgen diffraktometrialla (XRPD, X-ray powder diffractometry) ja polarisoidun valon mikroskopian (PLM, polarized light microscopy) avulla. Työn toissijaisena tavoitteena on etsiä eroja polymeerien sekoittuvuudessa itrakonatsolin kanssa sekä pyrkiä selvittämään kahden polymeerin yhteiskäytön mahdollista hyödyllisyyttä. Kehitetyllä menetelmällä voitiin pienellä lääkeainemäärällä valmistaa sekoittunut amorfinen dispersio useissa tapauksissa 10-20 % itrakonatsolipitoisuudella. Käytettyjen analyysimenetelmien detektiorajan puitteissa käytetty pieni lääkeainemäärä riitti ainakin melko hyvin. MTDSC-menetelmän analyysiparametreilla ei havaittu olevan suurta vaikutusta menetelmällä saatuihin tuloksiin tässä tutkimuksessa, mikä helpottaa kyseisen menetelmän käyttöä. Käytettyjen analyysimenetelmien antamat tulokset olivat osittain ristiriitaisia, minkä takia on suositeltavaa käyttää useita analyysimenetelmiä rinnakkain tai sellaisia menetelmiä, jotka yhdistävät useita analyysitekniikoita. Työssä havaittiin, että sekoittuneiksi ja amorfisiksi tulkituista dispersioista suuremmassa osassa oli enemmän HPMC-AS:ää kuin PVP K30:tä. Tämän arveltiin johtuvan itrakonatsolin ja HPMC-AS:n välille mahdollisesti muodostuvista ionisidoksista sekä PVP K30:n hygroskooppisuuden aiheuttamasta liikkuvuuden lisääntymisestä ja siten itrakonatsolimolekyylien törmäysten lukumäärän kasvusta. Polymeerien yhteiskäytöstä näytti olevan hyötyä erityisesti silloin, kun PVP K30:n määrä oli pieni (90/10 polymeerisuhde). Tämän havainnon syyksi arveltiin käytettyjen liuottimien (DCM ja metanoli) eriaikaista haihtumista sekä haihduttamisvaiheen hitautta. Havaitun ilmiön selittämiseksi ja varmentamiseksi tehtiin NMR-mittaukset (nuclear magnetic resonance), joilla pyrittiin selvittämään liuotinjäämien koostumusta ja liuottimien haihtumista. Dispersioita ja itrakonatsolia yksin tutkittaessa havaittiin, että…

The main effect of the microabrasion in the enamel is significant erosion. However, there is a gap in the literature about validated and reproducible assessment of the depth of erosion in the enamel surface which is originally curve. AIMS: Evaluate depth of erosion and mineral loss of enamel produced by microabrasion technique in original coronary surface of human teeth. METHODS AND MATERIALS: 40 extracted human molars were randomly spited in four groups, with 10 specimens each, in accordance with the microabrasive treatment: AC- 18% hydrochloric acid and pumice, AF 37% phosphoric acid and pumice, OP Opalustre and WRM Whiteness RM. Each specimens had buccal surface´s laterals isolated so that the central area received the microabrasion treatment. After this procedure, transverse slices not demineralized were prepared and submitted to microradiography and analysis in Polarized Light Microscope. One own terminology had created for the morphology of the interface enamel normal-microabrasioned. This served as base to introduction of a profilometry technique with analysis of digital images, in order to get the depth of erosion on microabrasion´s area. The Intraclass Correlation Test was applied to test technique´s reproducibility. The mineral loss and the depth which it happened had analyzed by transverses plotted at equidistant points of the limit enamel normal-microabrasioned. The dates were analyzed with ANOVA test (p < 0.05). RESULTS: The profilometry technique achieved a good reproducibility (Intraclass Correlation Test of 0,9998) and was validated internally. The AC group was the most aggressive, with a greater depth of erosion (110,51 ± 41,21 μm), and a greater mineral loss (13 ± 3 peso %), with significant difference between WRM group (p < 0,05; 9,41± 4,4 peso %) and OP group (p < 0,05; 9,0 ± 3,8 peso %). The OP group, on the other hand, was the less aggressive, with the lowest values in all parameters analyzed, presenting depth of erosion less than AC group (p < 0,0001), WRM group (p < 0,001; 86,24 ± 27,99 μm) and AF group (p < 0,05; 74,46 ± 42,06 μm). The others two groups achieved intermediate results for depth of erosion and mineral loss. The depth of mineral loss was greater than on AF group (31,38 ± 20,30 μm), however, there wasn´t statistical difference between the groups. CONCLUSIONS: Based on own terminology for the interface enamel normalmicroabrasioned and on the implementation of new technique of profilometry, the agents tested showed a significant…

▼ Enamel is one of the most important structures of the tooth, both from a functional and esthetic point of view. Primary enamel carries registered information regarding metabolic and physiological events that occurred during the period around birth and the first year of life. Detailed knowledge of normal development and the structure of enamel is important for the assessment of mineralization defects. The aim of the thesis is to add more detailed information regarding the structure of primary enamel. The structural appearance of the neonatal line and the quantitative developmental enamel defect, enamel hypoplasia, was thoroughly investigated with a polarized light microscope, microradiography and scanning electron microscope. X-ray microanalysis of some elements was also performed across the enamel and the neonatal line. Postnatal mineralization of enamel at different ages and from different individuals was studied regarding the chemical content, by using secondary ion mass spectrometry. The enamel’s response to demineralization was investigated in relation to the individual chemical content and the degree of mineralization of the enamel, by using polarized light microscope, microradiography, scanning electron microscope and X-ray microanalysis. The neonatal line is a hypomineralized structure seen as a step-like rupture in the enamel matrix. The neonatal line is due to disturbances in the enamel secretion stage. The enamel prisms in the postnatal enamel appeared to be smaller than the prenatal prisms. The hypoplasias showed a rough surface at the base and no aprismatic surface layer was seen in the defect. The enamel of the rounded border of hypoplasia appeared to be hypomineralized, with the bent prisms not being densely packed. Mineralization of enamel is a gradual process, still continuous at 6 months postnatally in the primary mandibular incisors. The thickness of the buccal enamel is reached at 3-4 months of age. Demineralization of enamel depends on the degree of mineralization and the chemical content of the enamel exposed. In a more porous enamel, deeper lesions will develop. The posteruptive maturation has a beneficial effect on the enamel’s resistance to demineralization.

▼ Os bisfosfonatos representam uma classe de drogas que agem sobre o metabolismo ósseo e são amplamente utilizadas na prevenção e tratamento de estados osteopênicos e osteoporóticos. Os objetivos do presente estudo foram avaliar, in vivo, o efeito do uso sistêmico de alendronato sódico: na densidade mineral óssea de ratos, por meio da densitometria óptica radiográfica e da técnica de absortometria radiológica de dupla energia (DXA); e nas estruturas dentárias mineralizadas de incisivos murinos, por meio da espectrometria na região do infravermelho, espectroscopia de fluorescência, microdureza transversal, microscopia eletrônica de varredura e microscopia de luz polarizada. Foram utilizados 45 ratos Wistar, com 36-42 dias de idade, pesando em média 200-230g, os quais foram divididos em dois grupos: experimental (n= 25) e controle (n= 20). No grupo experimental foram administradas duas doses semanais de 1mg/Kg de alendronato de sódio quimicamente puro diluído em água destilada, via gavagem, enquanto que os animais do grupo controle receberam apenas água destilada. Decorrido o período de 60 dias, os animais foram mortos por sobredose anestésica e, em seguida, foram extraídos os incisivos superiores e removidas as tíbias. As tíbias foram submetidas à avaliação da densidade mineral óssea por meio de análise radiográfica e da técnica de absortometria radiológica de dupla energia (DXA). Os incisivos superiores foram submetidos às seguintes avaliações: análise química por espectrometria na região do infravermelho e espectroscopia de fluorescência, microdureza transversal do esmalte e da dentina; microscopia eletrônica de varredura e microscopia de luz polarizada. Os resultados numéricos obtidos foram submetidos à análise estatística por meio do teste não-paramétrico de Kruskal-Wallis, utilizando o software SAS (Statistical Analysis System) for Windows versão 9.1.3. O nível de significância adotado foi de 5%. O grupo experimental apresentou valores de densidade mineral óssea superiores (p<0,05) em relação ao grupo controle, pelos métodos da densitometria óptica radiográfica e DXA. A análise química pelos métodos de espectrometria na região do infravermelho e espectroscopia de fluorescência permitiu detectar a presença do alendronato na estrutura dentária mineralizada do grupo experimental e que a porcentagem dessa incorporação foi de 0,0018% por elemento dental. Os resultados da microdureza transversal do esmalte e da dentina não revelaram diferença estatisticamente significante entre os grupos experimental e controle (p>0,05). Não foram observadas diferenças morfológicas significativas entre as amostras de ambos os grupos por meio da análise por microscopia eletrônica de varredura e microscopia de luz polarizada. Com base nos resultados obtidos, conclui-se que o tratamento com alendronato sódico provocou aumento na densidade mineral óssea da metáfise proximal da tíbia e que o alendronato incorporou-se nas estruturas dentárias mineralizadas, porém sem provocar efeitos significativos na microdureza e na morfologia… Advisors/Committee Members: Paulo Nelson Filho, Maria de Lourdes de Andrade Massara, Raquel Assed Bezerra da Silva.

▼ ABSTRACT Preterm birth is associated with medical complications and treatments postnatally and disturbances in growth and development. Primary and permanent teeth develop during this postnatal period. The overall aim of the present thesis was to elucidate the effects of preterm birth and postnatal complications on oral health and the dentoalveolar development during adolescence, and to study the effects of preterm birth on caries during childhood, in a well-defined group of preterm infants. In the same group, explore the development of the primary and permanent teeth and compare the results with a matched control group and control teeth. The subjects consisted of 40(45) of 56 surviving infants, born <29 weeks of gestational age (GA), and matched healthy children born at term. The material consisted of 44 teeth from 14 of the preterm adolescents and 36 control teeth from healthy children. Clinical examinations and dental cast analysis were performed during adolescence and morbidity was noted. Retrospective information from medical and dental records was obtained. Dental enamel was analyzed in a polarized light microscopy, and scanning electron microscopy. Further, chemical analyses of enamel and dentin were performed with X-ray microanalysis. The results showed that during adolescence, more preterms had plaque and gingival inflammation, lower salivary secretion, more S. mutans and severe hypomineralization. Retrospectively, less caries was noted at six years of age, but more children had hypomineralization in the primary dentition. Angle Class II malocclusion, large over-bite and deep bite associated with medical diagnoses were frequent. Furthermore, smaller dental arch perimeters in girls, at 16 years of age, and smaller tooth size in the incisors, canines and first molars were found. The morphological findings were confirmed in the XRMA analyses. In postnatal enamel, varying degrees of porosities >5% and incremental lines were seen. Lower values of Ca and Ca/C ratio and higher values of C were found. Ca/P ratio in both enamel and dentine indicates normal hydroxyapatite in both groups. No single medical diagnosis, postnatal treatment or morbidity in adolescents could explain the findings. As a conclusion, there are indications for poor oral outcome in this group of preterm infants during adolescence, and disturbed mineralization in primary teeth

The aim of the present work is to classify co-registered pixels of stacks of polarized light images of iron ore into their respective crystalline grains or pores, thus producing grain segmented images that can be analyzed by their size, shape and orientation distributions, as well as their porosity and the size and morphology of the pores. Polished sections of samples of hematite-rich ore are digitally imaged in a rotating polarizer microscope at varying planepolarization angles. An image stack is produced for every field of view, where each image corresponds to a polarizer position. Any point in the sample is registered to the same pixel coordinates at all images in the stack. The resulting set of intensities for each pixel is directly related to the orientation of the crystal sampled at the corresponding position. Multivariate analysis of the sets of intensities leads to the classification of the pixels into their respective crystalline grains. Individual hematite grains of iron ore, as well as their pores, are segmented. The results are compared to those obtained by visual point counting methods.

O objetivo do presente trabalho é classificar pixels co-registrados de pilhas de imagens de luz polarizada de minério de ferro nos seus respectivos grãos cristalinos ou poros, produzindo assim imagens segmentadas por grãos que podem ser analisados quanto às suas distribuições de tamanho, forma e orientação, bem como sua porosidade, tamanho e forma dos poros. Seções polidas de amostras de minério de ferro rico em hematita foram imageadas difratalmente em um microscópio com polarizador giratório em ângulos variados de polarização. Uma pilha de imagens foi produzida para cada campo na qual cada imagem corresponde a uma orientação do polarizador. Cada ponto na amostra foi registrado nas mesmas coordenadas em todas as imagens da pilha. O conjunto resultante de intensidades de cada pixel está diretamente relacionado com a orientação do cristal amostrado na posição correspondente. A análise multivariada dos conjuntos de intensidades leva à classificação dos pixels nos seus respectivos grãos cristalinos. Grãos individuais de hematita do minério de ferro, bem como os seus poros foram segmentados. Os resultados foram comparados com aqueles obtidos pelo método de contagem dos pontos, ou seja, por inspeção visual.

FAPEMIG - Fundação de Amparo à Pesquisa do Estado de Minas Gerais

As fibras transeptais situam-se na lâmina própria da gengiva entre dois dentes adjacentes. São comumente descritas como um grupo de fibras colágenas inseridas no cemento de um dente que seguem diretamente por sobre a crista óssea alveolar inserindo-se em uma região correspondente no cemento do dente adjacente. De maneira distinta, relatou-se na literatura que as fibras transeptais não são contínuas ao longo de toda sua extensão; são originadas dos dentes adjacentes, entrelaçando-se na região central do espaço interproximal. Com o presente estudo, objetivou-se avaliar e quantificar o arranjo das fibras gengivais transeptais empregando-se análise histomorfométrica e histoquímica em cortes histológicos sagitais da região entre primeiro e segundo molares da maxila de 12 ratos Wistar machos. As fibras colágenas foram coradas pelo método de picro-sirius e analisadas por microscopia de luz polarizada linear, processamento e análise digital de imagem baseados em métodos de filtragem e medição por transformada de Fourier. Foram realizadas medidas histomorfométricas de orientação, densidade e dimensão fractal das fibras. O brilho máximo apresentado pelas fibras foi mensurado pelo histograma de intensidade. Os parâmetros quantitativos foram comparados entre três regiões de interesse ao longo da extensão da gengiva interproximal ocupada pelas fibras transeptais utilizando-se análise de variância (ANOVA) seguida de testes post hoc de Bonferroni ou Tamhane T2. Houve um aumento significativo (p < 0,05) nos parâmetros de densidade de ocupação e dimensão fractal das fibras pertencentes à região central quando comparada às regiões próximas aos dentes, sem haver diferença na orientação e na intensidade de brilho das fibras. Os resultados demonstraram quantitativamente um arranjo mais denso de fibras na região central, reforçando o conceito de que as fibras transeptais entrelaçam-se nesta região.

The transeptal fibers are located in the lamina propria of the gingiva between adjacent teeth. They are often described as a group of collagen fibers embedded in the cementum of one tooth that follows a straight path over the alveolar bone crest and embeds itself in the cementum of the adjacent tooth. In a distinct way, it was reported in the literature that the transeptal fibers are not continuous over its full length but originates from the adjacent teeth interlacing in the central area of the interproximal gingiva. The present study aimed to evaluate and quantitate the gingival transseptal fibers arrangement by histomorphometry and histochemistry of sagittally cut tissue sections of the interdental region between first and second maxilar molar teeth of 12 male Wistar rat. The collagen fibers were stained with Picrosirius red staining and assessed with linear polarized light microscopy, digital image processing and analysis based on Fourier transform measurements and filtering techniques. Histomorphometrical parameters like fiber orientation, area fraction and fractal…

▼ Implant prostheses have complications that compromise peri-implant health and marginal bone. In addition to pathogenic bacterial biofilm, other determinants, such as implant surface deterioration, Ti particulates in peri-implant tissues, and functional stress have been reported as influencing peri-implant tissue stability. Aim: This thesis investigated the origin and presence of Ti particles in healthy and diseased peri-implant human tissues. Three trials evaluated the effect of acid-forming bacteria and mechanical instrumentation on Ti discs, and the effect of loading on implant surfaces on human participants. Methods: Four experiments involving a combination of in vitro and in vivo trials were performed. The first identified Ti particles in peri-implantitis tissues. Tissue specimens were analyzed under polarized light-microscopy (LM), scanning-electron-microscopy (SEM) and energy-dispersive X-ray spectrometry (EDS) analysis. In the second, a microbiological protocol incubated Ti discs achieving viable biofilm, which were investigated in-vitro for microbial-induced-corrosion. The third was an in-vitro trial evaluating topographic and composition changes by ultrasonic instrumentation on TI discs. Surface changes were evaluated using SEM, confocal-laser-scanning-microscopy (CLSM), and EDS. Rinsing solutions were evaluated using induced-coupled-plasma-mass-spectroscopy (ICPMS). The fourth experiment was a human trial on single implant crowns after five years. Exfoliative cytology samples from peri-implant mucosa and junctional epithelial, and control tooth mucosa sites were evaluated using LM, SEM and EDS. ICPMS was carried out on the exfoliative cytology microbrushes. Clinical peri-implant parameters were determined. Results: Firstly, the presence of Ti particles in peri-implantitis tissues was confirmed in 88% of the samples. Granular foreign material was scattered within the connective tissue and the epithelium layer. In most cases the inflammatory infiltrate contained a mixture of acute and chronic inflammatory cells. In the second experiment acid-forming bacterial colonisation of the disc surface was evident after 24 hours and maintained throughout the 7-day observation period. Although Ti isotopes should some variation in the inoculated growth media, ICPMS measurements were hindered due to the high concentrations of sodium (Na) and phosphorus (P) in the broth, this created backscattering during the analyses. The third experiment ultrasonic instrumentation of Ti discs demonstrated significant surface topographical alterations. ICPMS analysis of the rinsing solutions identified Ti and other metal traces. In the fourth experiment, the exfoliative internal and external cytology smears showed black scattered foreign material, which were also noted with SEM and EDS. More particles were identified at the level of the implant-abutment interface when compared to the external mucosal smears. The presence of these particles did not influence peri-implant health. Conclusions: Peri-implantitis biopsies… Advisors/Committee Members: Duncan, Warwick (advisor).
