During the time of preparation and storage, solutions of the drugs are in permanent contact with packaging materials that can release undesirable substances to the solution. Several factors may influence the release of packing materials, and factorial design (FD) is a useful tool for analyzing the phenomenon. The aim of this study was the determination of quality parameters for Homeopathic solid (globules) and liquid (drops) dosage forms. It was carried out analysis in homeopathic globules for weight variation, mechanical strength, and moisture content uniformity. For liquid preparations, standard solutions were prepared from natural rubber bulbs, which were subjected to exhaustive extraction with two ethanol solutions (30 and 70%) in the ultrasonic bath for 20 minutes at 25?C and 50?C in three successive cycles. Studies of transfer have been made within five days, by spectrophotometric analysis in the UV region at 312 nm with λm?x and 323 nm for samples in 70% ethanol and 30% respectively. PH values were analyzed. We also conducted two FD studies, where the first, the three-level variables were solvent (chloroform, ethanol and nhexane), sample mass (30, 60 and 90mg), particle size (large disk, small disk and powder sample). In the second study, the solvent level variables were different ethanolic degrees (EtOH 30%, 70% and pure). The percentage of lending in the solutions was 5.5%, 12.4%, 24.2% and 41% of the total estimated in the reference solution. The values of rate constants of transfer were determined in the order of 0.0134 days-1 and 0.0232 days-1 in absorbance values, the solutions in ethanol at 30% and 70% respectively. These results suggest that the speed of transfer of materials from rubber is affected both by the nature of the vehicle as by the temperature / Todo medicamento, quer seja alop?tico ou homeop?tico, deve passar por rigoroso controle de qualidade, o qual deve ratificar as suas caracter?sticas ao longo de todo o per?odo de validade. Durante o tempo de preparo e armazenamento, as solu??es dos medicamentos est?o em contato permanente com os materiais de embalagem que podem liberar subst?ncias indesej?veis para a solu??o. V?rios fatores podem influenciar a libera??o de materiais da embalagem, e planejamento fatorial (PF) ? uma ferramenta ?til para analisar o fen?meno. O objetivo deste trabalho foi a determina??o de par?metros de qualidade para Formas Farmac?uticas Homeop?ticas s?lidas (gl?bulos) e liquidas (gotas). Foi efetuada a avalia??o dos gl?obulos homeop?ticos no que diz respeito ? sua varia??o de peso, testes de resist?ncia mec?nica, uniformidade de conte?do e umidade. Para as prepara??es liquidas, preparamos solu??es de refer?ncia a partir de bulbos de borracha natural, os quais foram submetidos ? extra??o exaustiva com duas solu??es de etanol (30 e 70%), em banho de ultrassom durante 20 minutos a 25?C e 50?C, em tr?s ciclos sucessivos de 24 horas. Os estudos de ced?ncia foram efetuados num tempo de cinco dias, atrav?s de an?lise espectrofotom?trica na regi?o UV com λm?x em 312 nm e 323 nm para as amostras em etanol a 70% e 30%, respectivamente. Foram verificados valores de pH. Foram tamb?m realizados dois estudos de PF, onde no primeiro, as tr?s vari?veis de n?vel foram solvente (clorof?rmio, etanol e n-hexano), massa de amostra (30, 60 e 90mg), a forma de amostra (grande disco, disco pequeno, a amostra em p?). No segundo estudo, as vari?veis de n?vel solvente foram gradua??es etan?licas diferentes (EtOH 30%, 70% e puro). O percentual de ced?ncia nas solu??es foi de 5,5%, 12,4%, 24,2% e 41% do total estimado na solu??o de refer?ncia. Os valores das constantes de velocidade de ced?ncia foram determinados na ordem de 0,0134 dia-1 e 0,0232 dia-1, em valores de absorb?ncia, nas solu??es em etanol a 30% e 70%, respectivamente. Esses resultados sugerem que a velocidade de ced?ncia de materiais a partir da borracha ? afetada tanto pela natureza do ve?culo como pela temperatura

In this work, a morphological and immunohistochemical study was carried out in rat parotid glands, which were submitted to obstruction of the main excretory duct suffering atrophy at varied time intervals, with the aim of appraising the behavior of myoepithelial cells during the process of glandular atrophy. It was analized the immunohistochemical expression of calponin which detects myoepithelial cells in the parotids of 28 animaIs, which were divided into 7 groups, each one made up of 4 rats, afier the ductal ligature procedure, in the following time intervals: zero hour (control), 24 hours, 7, 15, 21, 30 and 60 days. Analysis of the immunohistochemicaI profile was carried through in which the calponin expression was veritied through its distribution pattem and numericaI index. All specimens exhibited positivity for calponin in myoepithelial cells which were distributed around the acini and the ductaI structures, a small number of positiveIy marked cells being detected in the controI group and in the 24-hour group when compared to subsequent ones, where it was perceived a Iarge increase in the number of positiveIy marked cens, mainly surrounding the ductiform structures which originated during the obstruction time. Upon application of statistical tests it was verified that the rise in the number the myoepithelial positive cells for calponin, when the control groups (zero hour) was compared to the 7, 15,21, 30 and 60-day groups afier obstruction, was statistica1ly significant. It was concluded then that the detected rise probably carne about due to an elevation in the rate of proliferation of the myoepitheliaI cells subsequent to the ductal obstruction, associated with a growing resistance of these cells to glandular atrophy. / A atrofia glandular ? uma das diversas altera??es que podem acometer as gl?ndulas salivares,causada geralmente por les?es obstrutivas como sialolit?ase,infec??es ou compress?o por processos neopl?sicos,dentre outros.No presente trabalho realizou-se estudo morfol?gico e imuno-histoqu?mico em gl?ndulas par?tidas de ratos submetidos ? obstru??o do ducto excretor principal,sofrendo atrofia em intervalos variados de tempo,visando avaliar o comportamento das c?lulas mioepiteliais durante o processo de atrofia glandular.Analisou-se a express?o imuno-histoqu?mica da calponina,a qual detecta c?lulas mioepiteliais,nas par?tidas de 28 animais divididos em 7 grupos com 4 ratos cada,ap?s o procedimento de ligadura ductal nos seguintes intervalos de tempo:zerohora(controle),24 horas,7,15,21,30 e 60 dias.Procedeu-se a an?lise do perfil imuno-histoqu?mico,onde verificou-se a express?o da calponina atrav?s de seu padr?o de distribui??o e ?ndice num?rico.Todos os esp?cimes exibiram positividade para a calponina nas c?lulas mioepiteliais,as quais se distribu?ram em torno dos ?cidos e estruturas ductais,sendo detectadas poucas c?lulas marcadas positivamente no grupo controle e no de 24 horas quando comparados aos grupos subsequentes,onde percebeu-se um grande aumento no n?mero de c?lulas marcadas positivamente,principlamente circundando as estruturas ductifformes que surgiram com o decorrer do tempo de obstru??o.Aplicados testes estat?sticos,foi verificado que o aumento no n?mero de c?lulas mioepiteliais positivas para a calponina,quando comparados o grupo controle(zero hora) com os grupos de 7,15,21,30 e 60 dias ap?s obstru??o,foi estatisticamente significativo.Concluiu-se que este aumento detectado,provavelmente ocorreu devido a uma eleva??o na taxa de prolifera??o das c?lulas mioepiteliais subsequente ? obstru??o ductal,associado a uma maior resist?ncia destas c?lulas ? arofia glandular.

These neoplasms share some characteristics, such as cellular origin and considerable production of extracellular matrix, however, with distinct biological behavior. The aim of the present study was to compare the expression of D2E1, D3E1 e D5E1 integrins in pleomorphic adenoma from minor and major salivary glands and ACCs. Furthermore, it was investigated possible differences in the expression of these integrins according to histological subtypes of ACC. Fourteen cases of pleomorphic adenoma from major salivary gland, fourteen cases from minor salivary gland and ten cases of ACC were selected. It was taken into consideration the presence or absence, localization and intensity of integrin immunoexpression. The cases of pleomorphic adenoma were grouped in order to compare the expression between the distinct neoplasms. It was observed a highly significant difference (p<0,0001) in relation to D2E1 integrin between the neoplasms since pleomorphic adenoma showed a pronounced immunostaining. It was not possible to perform statistical tests considering the D2E1 integrin expression; nevertheless, it could be observed a tendency of higher staining in pleomorphic adenoma. For comparative reasons the cases ACCs were divided in two groups: solid and tubular/cribriform. It was not detected significant differences in regard to D2E1 integrin; and statistical analysis could not be realized in relation to D3E1 and D5E integrin expression. However, it was also verified a tendency of absence or reduced expression in the solid subtype. It can be concluded that the reduced D2E1 integrin expression observed in CACs may be related to a lesser degree of cell differentiation in this neoplasm and the reduced D5E1 integrin expression can be associated with aggressive biological behavior. Moreover, the absence and/or reduced expression of the studied integrins in solid ACC suggests a role in pathogenesis and more aggressive biological behavior of this histological subtype / O adenoma pleom?rfico e o carcinoma aden?ide c?stico (CAC) representam neoplasias de gl?ndula salivar benigna e maligna, respectivamente, as quais compartilham algumas caracter?sticas como a mesma origem celular e uma marcante presen?a de matriz extracelular, apresentando, por?m, comportamentos biol?gicos distintos. O prop?sito desta pesquisa consistiu em comparar a express?o das integrinas D2E1, D3E1 e D5E1 em adenomas pleom?rficos de gl?ndula salivar menor e maior e CACs. Al?m disso, procurou investigar se havia diferen?as na express?o destas integrinas entre os subtipos histopatol?gicos do CAC. Foram selecionados 14 casos de adenoma pleom?rfico de gl?ndula salivar maior, 14 casos de gl?ndula salivar menor e 10 casos de CACs. Analisou-se a presen?a ou aus?ncia, localiza??o e intensidade de marca??o das integrinas. Os dois grupos de adenomas pleom?rficos foram reunidos em um s? para fazer a compara??o entre os dois tumores. Verificou-se que houve diferen?a estat?stica altamente significativa (p<0,0001) para a integrina D2E1 entre os dois tumores, apresentando o adenoma pleom?rfico, uma marca??o mais intensa para esta integrina. Em rela??o ? integrina D5E1 n?o foi poss?vel a realiza??o de testes estat?sticos, ficando patente, por?m, que houve uma tend?ncia da referida integrina ser mais intensamente expressa no adenoma pleom?rfico. Para an?lise comparativa, os CACs foram subdivididos em 2 grupos: s?lido e tubular/cribriforme. Para a integrina D2E1 observou-se que n?o houve diferen?a estatisticamente significativa e em rela??o ? D3E1 e D5E1 n?o foi poss?vel a realiza??o do teste estat?stico; no entanto, tamb?m foi verificada uma clara tend?ncia para os casos do subtipo s?lido apresentarem express?o ausente ou reduzida das integrinas avaliadas. Concluiu-se que a reduzida express?o da integrina D2E1 observada nos CACs, pode estar relacionada com a menor diferencia??o das c?lulas deste tumor e ? poss?vel que a reduzida express?o da D5E1, possa estar implicada em seu comportamento mais agressivo. Al?m disso, sugere-se que a aus?ncia e/ou redu??o da express?o das integrinas pesquisadas nos casos do subtipo s?lido, pode desempenhar algum papel na patog?nese e no comportamento biol?gico mais agressivo deste subtipo tumoral

L’ostéopétrose est une pathologie osseuse caractérisée par des os denses et fragiles principalement due à l’incapacité des ostéoclastes, cellules d’origine hématopoïétique, à résorber le tissu osseux. La forme la plus sévère de cette maladie génétique est l’ostéopétrose autosomale récessive infantile due à une mutation du gène Ostm1 (Protéine transmembranaire de type 1 associée à l'ostéopétrose). Le gène Ostm1 est exprimé principalement dans la lignée des cellules hématopoïétiques, mais aussi dans le système nerveux central et les mélanocytes. Cette mutation développe plusieurs symptômes comme l’apparition d’une couleur de pelage gris chez la souris, une anémie sévère, une sensibilité aux infections et des troubles neuronaux chez l’homme et la souris. Afin de mieux comprendre cette maladie, nous avons généré des souris transgéniques sur un fond génétique grey-lethal (gl) dans lesquelles l’expression d’Ostm1 est ciblée à un tissu spécifique. Nous avons caractérisé le gène Ostm1 responsable de la mutation ostéopétrotique spontanée gl chez la souris. La complémentation fonctionnelle des défauts hématopoïétiques a été obtenue dans les souris transgéniques PU.1-Ostm1-gl/gl mais ces souris meurent prématurément avec une neurodegénérescence sévère. Cette perte cellulaire affecte le système nerveux central dans son ensemble incluant la rétine. Ce mémoire porte sur le but d’établir le profil d’expression du gène Ostm1 dans la rétine puisque la perte du gène entraine une dégénérescence rétinienne. Pour définir le rôle d’Ostm1 dans la rétine, nous avons caractérisé son expression dans ce tissu (organe). Des analyses PCR, démontrent une expression d’Ostm1 dans l’œil total et enrichie dans la neurorétine et dans l’épithélium pigmentée (RPE). Après avoir caractérisé avec des marqueurs protéiques spécifiques les sous populations cellulaires de la rétine, in situ hybridation détecte l’expression préférentielle d’Ostm1 dans l’épithélium pigmentée (RPE) et la couche nucléaire interne (INL). Basé sur ce profil d’expression, nous avons induit dans un premier temps la perte de fonction d’Ostm1 spécifiquement dans le RPE. Dans un premier temps nous avons vérifié que l’expression de la recombinasse Cre seule n’est pas toxique. Nous avons ensuite induit la perte d’expression d’Ostm1 dans ces cellules et démontré que la perte d’Ostm1 dans le RPE se traduit par une perte graduelle des photorécepteurs avec l’âge. Ces résultats préliminaires suggèrent que l’expression post-natale d’Ostm1 dans le RPE est essentielle au maintien de l’homéostasie des photorécepteurs dans la rétine. / Osteopetrosis is a disease characterized by high bone density and fragility principally caused by impaired activity of osteoclasts, which are cells that reside in bone and dissolve bone tissue. The most severe form of osteopetrosis is infantile autosomal recessive osteopetrosis (ARO) which is caused by mutations in genes Ostm1. As Ostm1(osteopetrosis-associated transmembrane protein 1) is expressed in multiple hematopoietic stem cell lineages, melanocytes and the nervous system, mutations in Ostm1 can cause coat color change in mice as well as bone fragility, anemia, infections and neuronal disorders in humans and mice. To further the understanding of these conditions linked with Ostm1 loss, multiple tissue specific Ostm1 transgenic mice over an Ostm1 knockout (gl/gl) background were constructed. To better understand this disease, we characterized the Ostm1 gene responsible for the spontaneous osteopetrotic mutation grey- lethal (gl) in mice. Functional complementation of hematopoietic defects was obtained in PU.1-Ostm1-gl/gl transgenic mice, but these mice die prematurely with severe neurodegeneration. This indicates that Ostm1 has a crucial role in neuronal and retinal health. As a result, we wished to establish an expression profile of Ostm1 in all the layers of the retina to further decipher the role of Ostm1 in the retina. Polymerase chain reaction (PCR) of reverse-transcribed mRNA of separated sections of the eye demonstrate that Ostm1 is expressed in the whole eye, neuroretina and retinal pigmented epithelium (RPE). Further specific expression analyses were performed by in- situ hybridization which showed that Ostm1 is expressed specifically in the inner nuclear layer of the neuroretina as well as in the RPE. Based on this tissue expression pattern, we have constructed, for the first time, an RPE specific knockdown of Ostm1 expression and verified that the expression of Cre recombinase in this tissue is not toxic. The reduction of Ostm1 in the RPE of the eye resulted in gradual loss of photoreceptors of the retina. These preliminary results suggest that the post-natal expression of Ostm1 in the RPE is essential for maintaining the homeostasis of the photoreceptors of the retina.

It is believed that the expression of this protein denotes metabolic demand of the tumor cells and, thus its influence upon the formation of new blood vessels. Pleomorphic adenoma (PA) and the adenoid cystic carcinoma (ACC) and mucoepidermoid carcinoma (MEC) represent, respectively, the most commom benign and malignant tumors of salivary glands. The aim of this study was to analyze and compare the immunohistochemical expression of GLUT-1 and its correlation with angiogenesis in cases of PAs, ACCs and MECs considering their histological grades. The sample consisted of 20 PAs, 20 ACCs and 10 MECs. The cases were analyzed and classified according to their histological grades. The expression of GLUT-1 was evaluated in the parenchyma lesions, establishing the percentage of immunopositive cells, according to the following scores: 0 (no cell immunomarked), 1 (up to 25% of tumor cells immunostained), 2 (25 - 50% of tumor cells immunostained) and 3 (more than 50% of tumor cells immunostained). The angiogenic index was analyzed by counting the microvessels immunostained by anti-CD34 antibody, in 5 fields (200X). The analysis of the expression of GLUT-1 in tumor parenchyma showed statistically significant differences between benign and malignant groups (p = 0.022). The average number of microvessels in PAs was 40.4, 21.2 in ACCs and 66.5 in MECs, with significant differences between groups (p <0.001). When compared to the expression of GLUT-1 and angiogenic index as a whole, there was no significant correlation between the number of microvessels and the expression of GLUT-1 (r = 0.211, p = 0.141). In conclusion, the results of this study suggest not only that differences in biological behavior between PAs, ACCs and MECs may be associated to the expression of GLUT-1, but also that benign and malignant salivary gland present differences in the average number of microvessels, with higher levels considered more aggressive tumors. Furthermore, the number of newly formed microvessels can be independent of the metabolic demand of the tumor cells / A express?o da prote?na transportadora de glicose tipo 1 (GLUT-1), bem como a angiog?nese, t?m sido relacionadas ao comportamento cl?nico e agressividade em neoplasias de origem diversas. Acredita-se que a express?o desta prote?na denote a demanda metab?lica das c?lulas tumorais e, assim, a sua influ?ncia na forma??o de novos vasos sanguineos. O adenoma pleom?rfico (AP) e o carcinoma adenoide c?stico (CAC) e carcinoma mucoepiderm?ide (CME) representam, respectivamente, a neoplasia benigna e as malignas mais frequentes das gl?ndulas salivares. O prop?sito deste estudo foi comparar a express?o imuno-histoqu?mica da GLUT-1, bem como correlacionar com a angiog?nese em casos de APs, CACs e CMEs levando em considera??o suas grada??es histol?gicas. A amostra foi composta por 20 APs, 20 CACs e 10 CMEs os quais foram classificados de acordo com os graus histol?gicos apresentados. A express?o da GLUT-1 foi avaliada no par?nquima das les?es, estabelecendo-se o percentual de c?lulas imunopositivas, de acordo com os escores: 0 (nenhuma c?lula imunomarcada), 1 (at? 25% das c?lulas tumorais imunomarcadas), 2 (de 25-50% das c?lulas tumorais imunomarcadas) e 3 (mais de 50% das c?lulas tumorais imunomarcadas). O ?ndice angiog?nico foi analisado por meio da contagem de microvasos imunomarcados pelo anticorpo anti-CD34, em 5 campos (200x).

Os resultados do presente estudo sugerem que as diferen?as no comportamento biol?gico entre APs, CACs e CMEs podem estar relacionadas ? express?o da GLUT-1 e que tumores benignos e malignos de gl?ndulas salivares exibem diferen?as no n?mero m?dio de microvasos, com maiores ?ndices nos tumores considerados mais agressivos. Al?m disto, o n?mero de microvasos neoformados pode ser independente da demanda metab?lica das c?lulas tumorais

Diese Arbeit untersucht den Begriff der Liebe interdisziplinär in der Literatur und in der Musik in Deutschland und Russland in der Epoche der Romantik. Ausgegangen wird von der antiken Rede des Sokrates über Liebe und seiner Definition von ihr, welche Platon in seinem „Symposion“ nach Sokrates aufschreibt. Diese wird in die Zeit der Romantik zuerst in die deutsche und russische Literatur und später auf die Musik übertragen und untersucht. Welche Veränderungen treten im Verständnis des Begriffes auf? Welche Unterschiede oder möglichen Parallelen in den zwei auf den ersten Blick unterschiedlichen Kulturen und Mentalitäten sind vorhanden? Welchen Einfluss nehmen die Persönlichkeiten der Künstler auf diese Veränderungen? Die Ergebnisse werden auf einzelne Werke der Schriftsteller, A. Puschkin und E.T.A. Hoffmann, und auf die Vertonungen dieser Werke der Komponisten, P. Tschaikowski und R. Schumann, übertragen. Diese, in erster Linie literaturwissenschaftliche Untersuchung stellt den Begriff der Liebe in den Vordergrund, noch vor der Person oder dem Werk des Künstlers. Somit ist das vorrangige Ziel der Arbeit, der Rezeption der platonischen Liebestheorie während der Epoche der Romantik nachzugehen. Der Gedanke der eigenen Wandelbarkeit und der Entwicklung des Schönen und der Liebe als Stufenweg korrespondiert mit der Erkenntnisphilosophie der Romantiker. Das Thema der Liebe hat auch in der heutigen Zeit eine wichtige Bedeutung, vor allem weil die Medien immer öfter von einer Krise der moralischen Werte sprechen. Die Liebe ist transmedial, sie durchwandert das subjektive Leben des Menschen, die objektiven äußeren Voraussetzungen, die Kultur und die Mentalität, die Literatur und die Musik und sie bleibt eine Sehnsucht, ein Streben, eine Idee. Sie ist aktiv und überbrückt jegliche Schranken als Kommunikationscode oder als höchster Versuch, den die Natur macht, um das Individuum aus sich heraus und zu dem anderen hinzuführen. / This work examines the expression of Love in an interdisciplinary approach to literature and music in Germany and Russia during the Romantic Period. The starting point is Socrates’ classical discourse about Love and his definition of it, which Plato recorded in his Symposium. This will be applied to and examined in the Romantic Period, first in German and Russian literature and later in Music. What changes occur in the reception of this term? What differences or possible parallels can be determined in the two cultures and mentalities that are different at first sight? What is the influence of the respective artists on these changes? The results will be applied to the individual works of the writers A. Pushkin and E.T.A. Hoffmann as well as the musical settings of these works by the composers P. Tchaikovsky and R. Schumann. This examination, which is based primarily on literature and literary criticism, places the concept of Love in the foreground, even above the person or the work of the respective artist. Therefore, the primary goal of this work is to follow the reception of Plato’s “theory of love” during the Romantic Period. The concepts of one’s own inconstancy, the development of beauty, and the path of love correspond with the metacognitive philosophy of the Romantics. The subject of love has particular significance today because of the media’s frequent discussions about the crisis of moral values. Love is transmedial. It transcends the subjective lives of humans, the objective external conditions, culture and mentality, literature and music; and it remains a desire, an ambition, an idea. Love is active and bridges every boundary as a communicational code or as nature’s utmost attempt to lead an individual out of himself and to another.

This thesis deals with library for recording video in the background of 3D application. A library is designed to work under the Microsoft Windows and Linux operation systems.  It records image and also sound. Image recording is supported in OpenGL, Direct3D9, Direct3D10 and Direct3D11. To reduce video data size, library supports image compression using MJPG codec. Audio is recorded by WaveForm audio, Windows Core Audio or ALSA. Recorded sound is for whole operation system. A library is able to record up to two audio streams to accommodate possible microphone input. It can mix audio data together if needed. Output data are then written into AVI file. It is possible to write own text information as overlay that is rendered as part of application screen output.
