TARGETING DNA DAMAGE AND REPAIR TO OVERCOME THERAPY MEDIATED TUMOR IMMUNE EVASION AND HETEROGENEITY IN THE CONTEXT OF ONCOLYTIC VIRUS VACCINATIONKesavan, Sreedevi January 2021 (has links)
Due to the inevitable reality that most patients diagnosed with cancer will eventually relapse, modern oncology research has been forced to tackle this outcome primitively using combination therapies. Adoptive T-cell transfer with Oncolytic Virus Vaccination represents a new class of combination therapies that can facilitate the crosstalk of multiple aspects of the immune system such that they work in concert to prevent this outcome for many types of cancer. Despite this, immunosuppressive systems like those characterized in the B16F10-gp33 melanoma model pose a new problem for this approach. Typically, this model has total regression but is subsequently followed by relapse. Previous work from the Wan lab has suggested that this may be an outcome of total target gene deletion. Here we present two approaches to tackle this through the targeting of DNA repair pathways of the host cell. Our data can show that both VSV and Vaccinia infection/ propagation does lead to the generation of DNA damage but in the case of VSV this leads to incomplete cell lysis, and ultimately target gene loss via double-stranded DNA repair mechanisms. We were able to tackle the phenomenon following VSV administration by adding DNA repair inhibitors to the mix and showed that the proportion of cells that escaped after the loss of the target antigen was decreased by half when compared to the standard procedures. Additionally, this work also gave a preliminary understanding of how Vaccinia may achieve a similar outcome to this via its unique cytoplasmic replication mechanisms. / Thesis / Master of Science (MSc)

Uplatňování propagandy a metod řízení a regulace regionálního tisku v Československu 1948-1956 (na příkladu direktiv KV a OV KSČ a libereckého regionu) / xGroman, Martin January 2011 (has links)
English abstract The use of propaganda and methods of governing and regulation of the regional press in Czechoslovakia during 1948-1956 (using the example of the guidelines of KV and OV KSČ and the region around Liberec) The presented study follows the development of censorship and the methods of media and press control in Czechoslovakia from 1948 to1953, and in particular during 1956. This study focuses mainly on the methods and processes used by the Czechoslovak Communist Party to dominate the media and how it concentrated namely on the relationship between local and regional media and the centralized governance under the powerful influence of the Czechoslovak Communist Party. After February of 1948, the mass media in Czechoslovakia took on a different role than the one it had up until that time. Even so, up until 1953, there was no official censorship office and the media fell under the jurisdiction of the Party apparatus, or alternately under the Ministries of Education, Science and Arts or Information, which accordingly managed and influenced media content. However, it was still under the curatorship of the UV Czechoslovak Communist Party, as the following work will show. As will also be shown, after February of 1948 the Communist Party was unable to gain influence over society at various levels and...

Previous issue date: 2014-12-12 / Objetivos: Estimar a preval?ncia de altera??es do filme lacrimal e da doen?a
do olho seco (DOS), comparar as mudan?as na press?o intraocular (PIO) e
comparar as espessuras macular e da camada de fibras nervosas da retina
(CFNR), entre mulheres com s?ndrome dos ov?rios polic?sticos (SOP) e
mulheres saud?veis, estratificando-as em condi??es cl?nicas, metab?licas e
inflamat?rias. Metodologia: O estudo incluiu 45 mulheres com SOP e 47
mulheres saud?veis ovulat?rias submetidas a avalia??es cl?nico-ginecol?gicas
e oftalmol?gicas, incluindo proped?uticas para a avalia??o do filme lacrimal e
medida da PIO, e medi??o da espessura macular, da CFNR e par?metros do
disco ?ptico usando tomografia de coer?ncia ?ptica. Resultados: Tempo de
ruptura do filme lacrimal (TRFL; p=0.001) e impregna??o por fluoresce?na
(p=0.006) apresentaram diferen?as estatisticamente significantes entre os
grupos estudados. A preval?ncia de DOS foi de 44,4% nas portadoras de
SOP. Houve redu??o estatisticamente significativa do TRFL na presen?a de
SOP (p=0.001). Al?m disso, houve efeito estatisticamente significativo de
intoler?ncia ? glicose e s?ndrome metab?lica/inflama??o na impregna??o por
fluoresceina (p=0.004; p=0.015, respectivamente). A PIO encontrou-se
estatisticamente mais elevada no grupo SOP que no grupo controle (p=0.011).
Houve um aumento na m?dia do IPC (?ndice press?o-c?rnea) com a
associa??o entre SOP e da s?ndrome metab?lica (p = 0.005); A m?dia da
espessura da CNFR superior ao redor do nervo ?ptico foi estatisticamente mais
espessa nas volunt?rias com SOP que nas volunt?rias saud?veis (p=0.036);
Ap?s estratifica??o pela presen?a de resist?ncia insul?nica, as m?dias dos
subcampos das espessuras maculares ?macular interno temporal, macular
interno inferior, macular interno nasal e macular externo nasal, foram mais
espessas no grupo SOP que no grupo controle (p<0.05); Houve associa??o
significativa entre obesidade e resist?ncia insul?nica (p=0.037), e intoler?ncia ?
glicose (p=0.001), com aumento m?dio do componente principal 1 (CP1), e, na
presen?a de s?ndrome metab?lica (p<0.0001), com aumento m?dio do
componente principal 2 (CP2), respectivamente, em rela??o ? espessura
macular total. Na presen?a de obesidade e inflama??o, houve redu??o no
escore m?dio da CP2 (p=0.034), em rela??o ? espessura da CFNR na m?cula.
xviii
Conclus?es: H? uma associa??o da SOP, suas altera??es metab?licas e
inflamat?rias com altera??es do filme lacrimal e com mudan?as na PIO. A
diminui??o na espessura da CFNR macular e aumento da espessura total
macular est?o possivelmente associadas ?s altera??es metab?licas, e, o
aumento na espessura da CFNR ao redor do nervo ?ptico est?o provavelmente

Previous issue date: 2015-03-30 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / Conselho Nacional de Desenvolvimento Cient?fico e Tecnol?gico - CNPq / Os c?nceres que acometem os ?rg?os genitais masculinos e femininos, em conjunto com
o c?ncer de mama, s?o respons?veis por cerca de 20% dos ?bitos por c?ncer no mundo.
Conhecer os padr?es de mortalidade por esses c?nceres no Brasil, as mudan?as que se
produziram ao longo do tempo, os grupos mais vulner?veis e a carga de mortalidade que
se apresentar? no futuro s?o elementos b?sicos para a estrutura??o das a??es
assistenciais e de vigil?ncia do c?ncer. O objetivo desse estudo foi analisar as tend?ncias
de mortalidade pelos c?nceres que acometem ?rg?os que s?o espec?ficos a cada g?nero e
projetar a mortalidade por esses c?nceres at? o ano de 2030, para o Brasil, regi?es e
estados da federa??o. Trata-se de um estudo ecol?gico de base populacional que
analisou os ?bitos, ocorridos no per?odo 1996 a 2010, decorrentes dos c?nceres de colo
do ?tero, corpo do ?tero, mama feminina, ov?rios, vulva, vagina, pr?stata, p?nis e
test?culos, registrados no Sistema de Informa??o sobre Mortalidade; as informa??es
sobre popula??o foram obtidas do Instituto Brasileiro de Geografia e Estat?stica. Foi
aplicada a Regress?o loglineal (Joinpoint regression) com taxas padronizadas
(popula??o mundial: ASR-W) para estimar o Annual Percentage Change (APC), o
Average Annual Percentage Change (AAPC), o intervalo de confian?a 95% e os pontos
de inflex?o da curva; as proje??es foram calculadas atrav?s do programa Nordpred,
inscrito no programa R, utilizando o modelo idade-per?odo-coorte, analisando
posteriormente se as mudan?as que se produzir?o no futuro ser?o decorrentes da
exposi??o aos fatores de risco e/ou da estrutura da popula??o exposta ao risco. Todas as
an?lises tamb?m foram aplicadas para o conjunto de todos os ?bitos por c?ncer (com
exce??o dos c?nceres de pele n?o-melanoma). Para o Brasil, a mortalidade pelos
c?nceres de p?nis (APC=1,5% IC95% 0,7;2,3 p<0,05), test?culos (APC=1,6% IC95%
0,5;2,8 p<0,05) e ov?rios (APC=0,8% IC95% 0,1; 1,5 p<0,05), mostraram tend?ncia de
aumento, enquanto os c?nceres de vulva e vagina (APC=-0,1% IC95% -0,9; 0,7 p=0,8),
corpo de ?tero (APC= -0,3 IC95% -1,0; 0,5 p=0,4), mama (APC=0,4% IC95% -0,2;1,0
p=0,2) e de pr?stata (AAPC= 1,1% IC95% -0,2; 2,4 p=0,1) apresentaram tend?ncia de
estabilidade. A mortalidade por c?ncer de colo de ?tero apresentou tend?ncia de redu??o
(APC=-1,7% IC95%-2,2; -1,1 p<0,05). A an?lise do agrupamento de todos os ?bitos por
c?ncer observou tend?ncia de aumento na mortalidade para o sexo masculino at? o ano
de 2006 (APC= 1,2% IC95% 0,6;1,8 p<0,01), seguido de um per?odo de estabilidade.
Para o sexo feminino, a tend?ncia ? de estabilidade (APC=0,4% IC95% -0,2;-1,8
p=0,2). As taxas de mortalidade para todos os c?nceres analisados mostraram, de
maneira geral, tend?ncia de redu??o nas regi?es sul e sudeste, tend?ncia de aumento nas
regi?es norte e nordeste, e estabilidade para a regi?o centro oeste. Na proje??o da
mortalidade para o ano 2030, as regi?es norte e nordeste responder?o pelas maiores
taxas de mortalidade para os c?nceres analisados; todavia, para as demais regi?es, ser?
observada redu??o nas taxas em compara??o com o ?ltimo per?odo observado. Destacase
o c?ncer de test?culo, para o qual ser? observado aumento de 33% na carga da
mortalidade at? o ano 2030. Para os demais c?nceres, n?o ser?o observadas varia??es
consider?veis nas taxas de mortalidade para o Brasil entre o ?ltimo per?odo observado e
o ?ltimo per?odo projetado. A estrutura e o tamanho da popula??o brasileira ser?o os
fatores que explicar?o os padr?es de mortalidade por esses c?nceres no futuro, embora
para a regi?o nordeste, as varia??es ser?o explicadas, em maior medida, pelo aumento
do risco para esses c?nceres. Conclui-se, portanto, que existe uma marcante
desigualdade na distribui??o da mortalidade pelos c?nceres espec?ficos ao g?nero no
Brasil, onde as regi?es mais pobres apresentam um quadro de aumento significativo do
n?mero de ?bitos ao longo de uma s?rie hist?rica, e que em 2030, essas regi?es
responder?o pelas maiores taxas de mortalidade no pa?s, com ?nfase para os c?nceres de
p?nis, test?culos e ov?rios.

Primene polugrupa operatora u nekim klasama Košijevih početnih problema / Applications of Semigroups of Operators in Some Classes of Cauchy ProblemsŽigić Milica 22 December 2014 (has links)
<p>Doktorska disertacija je posvećena primeni teorije polugrupa operatora na rešavanje dve klase Cauchy-jevih početnih problema. U prvom delu smo<br />ispitivali parabolične stohastičke parcijalne diferencijalne jednačine (SPDJ-ne), odredjene sa dva tipa operatora: linearnim zatvorenim operatorom koji<br />generiše <em>C</em><sub>0</sub>−polugrupu i linearnim ograničenim operatorom kombinovanim<br />sa Wick-ovim proizvodom. Svi stohastički procesi su dati Wiener-Itô-ovom<br />haos ekspanzijom. Dokazali smo postojanje i jedinstvenost rešenja ove klase<br />SPDJ-na. Posebno, posmatrali smo i stacionarni slučaj kada je izvod po<br />vremenu jednak nuli. U drugom delu smo konstruisali kompleksne stepene<br /><em>C</em>-sektorijalnih operatora na sekvencijalno kompletnim lokalno konveksnim<br />prostorima. Kompleksne stepene operatora smo posmatrali kao integralne<br />generatore uniformno ograničenih analitičkih <em>C</em>-regularizovanih rezolventnih<br />familija, i upotrebili dobijene rezultate na izučavanje nepotpunih Cauchy-jevih problema viš3eg ili necelog reda.</p> / <p>The doctoral dissertation is devoted to applications of the theory<br />of semigroups of operators on two classes of Cauchy problems. In the first<br />part, we studied parabolic stochastic partial differential equations (SPDEs),<br />driven by two types of operators: one linear closed operator generating a<br /><em>C</em><sub>0</sub>−semigroup and one linear bounded operator with Wick-type multipli-cation. All stochastic processes are considered in the setting of Wiener-Itô<br />chaos expansions. We proved existence and uniqueness of solutions for this<br />class of SPDEs. In particular, we also treated the stationary case when the<br />time-derivative is equal to zero. In the second part, we constructed com-plex powers of <em>C</em>−sectorial operators in the setting of sequentially complete<br />locally convex spaces. We considered these complex powers as the integral<br />generators of equicontinuous analytic <em>C</em>−regularized resolvent families, and<br />incorporated the obtained results in the study of incomplete higher or frac-tional order Cauchy problems.</p>

Rehabilitación Virtual Motora: una Evaluación al tratamiento de pacientes con Daño Cerebral AdquiridoAlbiol Pérez, Sergio 30 June 2014 (has links)
El uso de la Realidad Virtual dentro del campo de la Rehabilitaci on Motora en
pacientes con Da~no Cerebral Adquirido (DCA) es un hecho cient camente contrastado
en los ultimos a~nos. Los prometedores y satisfactorios resultados que se
est an obteniendo en esta l nea de investigaci on (tanto a nivel cognitivo, como a
nivel motor), en conjunci on con los procesos terap euticos tradicionales, proporcionan
el auge de un nuevo hito dentro de la rehabilitaci on tradicional conocido
como Virtual Motor Rehabilitation cuyo acr onimo es (VMR), describi endolo como
Rehabilitaci on Virtual Motora (RVM).
Hoy en d a, el Da~no Cerebral Adquirido es uno de los principales problemas de
discapacidad y muerte en el mundo, donde las metodolog as propuestas dentro del
campo de la rehabilitaci on tradicional, proporcionan resultados prometedores y
esperanzadores. No obstante, este tipo de terapias presentan inconvenientes como
son la falta de motivaci on del paciente, que lleva a una limitada adherencia al
tratamiento, o las limitaciones de tiempo, espacio o coste que surgen en el proceso
rehabilitador.
Tradicionalmente, los principales experimentos realizados dentro del campo de la
Rehabilitaci on Motora, se han realizado en pacientes DCA post-agudos y agudos,
con escasas publicaciones basadas en el proceso rehabilitador motor de pacientes
DCA cr onicos. En la presente tesis se han desarrollado sistemas de Rehabilitaci on
Virtual para que, gracias al uso de dispositivos de bajo coste y las aportaciones
obtenidas por los especialistas cl nicos, se haya validado la hip otesis:
Mediante t ecnicas de rehabilitaci on virtual es posible obtener en pacientes
cr onicos una recuperaci on del equilibrio estad sticamente signi-
cativa, y similar a la que es posible obtener en pacientes agudos.
Los experimentos realizados en el proceso rehabilitador, junto con las validaciones
cl nicas realizadas en el Hospital Valencia al Mar, y el Instituto Valenciano de la
Discapacidad, han servido para obtener unos resultados contrastables y satisfactorios,
que corroboran la hip otesis de trabajo planteada. / Albiol Pérez, S. (2014). Rehabilitación Virtual Motora: una Evaluación al tratamiento de pacientes con Daño Cerebral Adquirido [Tesis doctoral]. Universitat Politècnica de València. https://doi.org/10.4995/Thesis/10251/38450

Extracts of <em> G. resinaceum </em> were allocated as a potential nephro- and hepatoprotective agents.<br />In summary, the overall biological potential of the analyzed species of the genus <em>Ganoderma</em> based on results for chemical and biological characterization indicate that they could be used as a nutraceuticals and food supplements in the future, with further the necessity of additional mycochemical investigation (especially terpenoids and polysaccharides) and other biological activity such as neuroprotective.</p>
