Since prolyl-leucyl-glycinamide (MIF-1) modifies the behavior of adult rats after treatment with neuroleptics, we examined whether MIF-1 would also modify adult behavior after treatment of neonatal rats with 6-hydroxydopamine (6-OHDA). Rats received 6-OHDA (100 μg i.c.v.) or diluent at 3 days after birth and either MIF-1 (2.0 mg/kg per day s.c. × 10 days) or diluent beginning at 28 or 29 days after birth. At 5 weeks, a low dose (0.1 mg/kg s.c.) of apomorphine increased the distance traveled, time in ambulation, number of stereotypic movements, and number of movements per time in stereotypy, but decreased the time in stereotypy in the 6-OHDA group. MIF-1 (× 7 or 8 days) showed a tendency to attenuate the increased number of movements and significantly (P < 0.05) reduced all of the other effects of neonatal 6-OHDA. Behavior induced by higher doses of apomorphine in the 6-OHDA group (reduced licking and head nodding; increased paw treading, taffy pulling and self-biting) were not attenuated by MIF-1. At 38 or 39 days, total in vitro binding of [3H]SCH-23390 and [3H]spiroperidol to striatal homogenates was not altered in any of the groups. The findings demonstrate that specific early developmental alterations in apomorphine-induced behaviors can be modified by treatment of adult rats with MIF-1, even in the absence of overt changes in the binding of striatal dopamine D-1 and D-2 receptors.

Reinfection is very common among patients, causing symptoms such as cold or allergy. However, in children, immunosuppressed patients and elderly infection is exacerbated leading to hospitalization and in some case, even death. The number of hospitalizations each year is alarming, even more so because up to now there is still no vaccine for RSV. Tissue damage in the lung caused by RSV leads to an immune response, where infected cells signal activation of signaling pathways, production of reactive oxygen species (ROS), and massive production of inflammatory mediators. Among this production is the macrophage migration inhibitory factor (MIF), which is a pro-inflammatory cytokine, which has been shown to play an important role in the immune response. Knowing this importance, we evaluated MIF expression macrophages from BALB/c mice. The cells were infected with different concentrations of RSV and analyzed by western blot, real-time PCR and Cytometric Bead Array (CBA). After confirmation of MIF expression by the infection, different inhibitors of signaling pathways and ROS were used to evaluate its importance for the expression of MIF. From the results obtained, we showed the dependence of ROS, 5-lipoxygenase (5-LOX), COX, PI3K and partially of P38 MAPK, for MIF expression, besides the need for viral activity. MIF was shown to be important for the release of cytokines such as TNF?, MCP-1 and IL-10. Based on this information MIF may play an important role in the exacerbation of infection, so it was extremely important to explore mechanisms involved in the expression of MIF in relation to RSV. / O V?rus sincicial respirat?rio (VSR) ? a maior causa de infec??o em crian?as at? os cinco anos de idade. A reinfec??o ? muito comum entre os pacientes, causando sintomas como de uma gripe ou alergia, no entanto, em crian?as, pacientes imunossuprimidos e idosos a infec??o ? muito mais exacerbada, o que acaba levando a necessidade de interna??o, podendo levar o paciente a ?bito. O n?mero de interna??es a cada ano ? alarmante, ainda mais que at? os dias atuais ainda n?o se tem uma vacina para o VSR. O dano tecidual no pulm?o, causado por VSR leva a uma resposta imune, onde c?lulas infectadas sinalizam para que ocorra a ativa??o de vias de sinaliza??o, produ??o de esp?cies reativas de oxig?nio (EROs) e tamb?m uma produ??o massiva de mediadores inflamat?rios. Dentre essa produ??o, est? o fator inibidor de migra??o de macr?fagos (MIF), que ? uma citocina pr?-inflamat?ria, que tem demonstrado um importante papel na resposta imune. Sabendo dessa import?ncia, avaliamos a express?o de MIF em macr?fagos de camundongos BALB/c. As c?lulas foram infectadas com diferentes concentra??es de VSR e analisadas por western blot, PCR em tempo real e Cytometric Bead Array (CBA). Ap?s a confirma??o da express?o de MIF pela infec??o, foram utilizados diferentes inibidores de vias de sinaliza??o e de EROs, para que fosse poss?vel avaliar sua import?ncia para a express?o de MIF. A partir dos resultados obtidos mostramos a depend?ncia de EROS, 5-lipoxigenase (5-LOX), COX, PI3K e parcialmente de P38 MAPK, para a express?o de MIF, al?m da necessidade de atividade viral. MIF se mostrou importante para a libera??o de citocinas como TNF ?, MCP-1 e IL-10. Baseado nessas informa??es MIF pode desempenhar um papel importante na exacerba??o da infec??o, sendo assim, foi de extrema import?ncia explorar mecanismos envolvidos na express?o de MIF em rela??o ao VSR.

A mensuração da função é importante na otimização do tratamento fisioterapêutico e alta hospitalar destes pacientes. Este estudo teve como objetivo descrever os resultados da reabilitação em pacientes submetidos a tratamento cirúrgico de clipagem aneurismática admitidos no Hospital das Clínicas da Universidade Estadual de Campinas. Os pacientes foram avaliados por meio dos seguintes instrumentos: escala clínica de Hunt ¿ Hess (na internação hospitalar), que avalia o estado clínico do paciente; a escala neurorradiográfica de Fisher (na internação hospitalar), que avalia a quantidade de sangue no espaço subaracnóide; medida de independência funcional (MIF) (no pós-operatório e alta hospitalar) e escala de prognóstico de Glasgow (na alta hospitalar). Os pacientes foram submetidos ao tratamento fisioterapêutico durante todo o período de internação (dois atendimentos diários). Para comparar os valores da MIF entre admissão e alta foi realizado o teste de Wilcoxon, para verificar a correlação entre os instrumentos de avaliação foi utilizado o coeficiente de correlação de Spearman. Foram avaliados 13 pacientes, 12 (92.31%) mulheres e um homem, com predomínio de aneurismas na artéria cerebral média (53.85%). A idade média foi de 51.62 (DP 13.04) anos. Ocorreu diferença estatística significativa entre as avaliações da MIF (admissão 56.92 ± 23.42; alta 91.77 ± 20.32; p < 0.001). Não foi encontrada correlação significativa entre a MIF e a escala clínica de Hunt-Hess (r = - 0.16282; p = 0.5951), escala neurorradiografica de Fisher (r = 0.06935; p = 0.8219) e a escala de prognóstico de Glasgow (r = 0.24972; p = 0.4106). Os pacientes apresentaram melhoras funcionais após o procedimento cirúrgico e tratamento fisioterapêutico demonstradas de forma quantitativa por meio da MIF e não foi encontrada relação das medidas clínicas com os resultados funcionais / Abstract: Subarachnoid hemorrhage results in critical motor and cognitive impairment which leads to dysfunctions causing a negative impact in quality of life. The functional independence measure (FIM) scale is the most widely accepted functional assessment measure in use in the rehabilitation community. The aim of this study was to describe the rehabilitation outcome after a surgical aneurysm occlusion realized in patients admitted in the Clinical Hospital of Campinas State University ¿ UNICAMP. Patients were submitted to the Hunt-Hess and Fisher assessment scales after admission in to the hospital; to the FIM after surgery; and to FIM and Glasgow Outcome Scale (GOS) after hospital discharge. The days in the hospital were counted, patients had physical therapy twice a day and the injured arteries were identified. Thirteen patients, 12 woman¿s (92,31%) with aneurysm predominant in middle cerebral artery (53,85%) were evaluated. The mean age was 51, 62 (DP 13,04) years old. The mean FIM rate, between the admission and the discharge period, was 34,85 (DP 20,85), with average of 5-69 points (p<0,001). There was non significant correlation between the FIM, Hunt-Hess, Fisher and GOS. The subarachnoid hemorrhage is a catastrophic neurologic event that results in motor and cognitive impairment. The FIM could have an important role in predict the neurorehabilitation outcome in acute aneurysmal subarachnoid hemorrhage / Mestrado / Ciencias Biomedicas / Mestre em Ciências Médicas

l-Prolyl-l-leucyl-glycinamide (MIF-1) is known to attenuate apomorphine-induced stereotypies in adult rats that are lesioned as neonates with 6-hydroxydopamine (6-OHDA). To test whether MIF-1 would affect dopamine (DA) agonist-induced and serotonin (5-HT) agonist-induced oral activity, both intact and neonatal 6-OHDA-treated rats were studied. Rats at 3 days from birth were injected with desipramine (20 mg/kg, IP), 1 h before 6-OHDA HBr (100 μg, salt form, in each lateral ventricle) or its vehicle, saline-ascorbic acid (0.1%). At approximately 6 months rats were treated with MIF-1 (0.1, 1.0, or 10.0 mg/kg, IP), 10 min before SKF 39393 HCl (1.0 mg/kg, IP) or m-chlorophenylpiperazine 2HCl (m-CPP 2HCl; 0.5 mg/kg, IP), DA D1 and 5-HT1C,2 receptor agonists, respectively. Although both agonists increased oral activity in control and neonatal 6-OHDA-treated rats, MIF-1 did not modify the response. In rats that received either of the three doses of MIF-1 for 21 consecutive days, there was still no observed effect of MIF-1 on the oral response of control and 6-OHDA-lesioned rats to SKF 38393 and m-CPP. These findings indicate that MIF-1 does not modify the oral activity response of supersensitized D1 and 5-HT1C receptors in adult rats that are lesioned neonatally with 6-OHDA.

Metal-organic frameworks (MOFs) have been intensely researched over the past 20 years. In this dissertation, metal-inorganic frameworks (MIFs), a new class of porous and nonporous materials using inorganic complexes as linkers, in lieu of traditional organic linkers in MOFs is reported. Besides novel MIF regimes, the previously described fluorous MOF "FMOF-1", is re-categorized herein as "F-MIF1". F-MIF-1 is comprised of [Ag4Tz6]2- (Tz = 3,5-bis-trifluoromethyl-1,2,4-triazolate) inorganic clusters connected by 3-coordinate Ag+ metal centers. Chapter 2 describes isosteric heat of adsorption studies of F-MIF1 for CO2 at near ambient temperatures, suggesting promise for carbon capture and storage. We then successfully exchanged some of these Ag(I) centers with Au(I) to form an isostructural Au/F-MIF1. Other, nonporous MIFs have been synthesized using Ag2Tz2 clusters with bridging diamine linkers 4,4'-bipyridine, pyrazine, and a Pt(II) complex containing two oppositely-situated non-coordinating pyridines. This strategy attained luminescent products better-positioned for photonic devices than porous materials due to greater exciton density. Chapter 3 overviews work using an entirely inorganic luminescent complex, [Pt2(P2O5)4]4- (a.k.a. "PtPOP") to form new carbon-free MIFs. PtPOP is highly luminescent in solution, but as a solid shows poor quantum yield (QY ~0.02) and poor stability under ambient conditions. By complexing PtPOP to various metals, we have shown a dramatic enhancement in its solid-state luminescence (by an order of magnitude) and stability (from day to year scale). One embodiment (MIF-1) demonstrates microporous character. Chapter 4 overviews the design and application of new MIF linkers. Pt complexes based upon (pyridyl)azolates, functionalized with carboxylic acid groups, have been synthesized. These complexes, and their esterized precursors, show strong luminescence on their own. They have been used to generate new luminescent MIFs. Such new MIFs may be useful toward future inorganic (LEDs) or organic (OLEDs) light-emitting diodes, respectively. The electronic communication along their infinite coordination structures is desirable for color tuning and enhanced conductivity functions, compared to the small molecules used in such technologies, which rely on intermolecular interactions for these functions.

Mémoire numérisé par la Direction des bibliothèques de l'Université de Montréal. / Les personnes âgées sont hébergées en milieu institutionnel suite à une diminution de leur niveau d'indépendance fonctionnelle. La majorité des résidents vivant dans un centre d'hébergement utilise un fauteuil roulant afin d'augmenter leur indépendance dans les déplacements ainsi que pour la réalisation des activités quotidiennes. Un nombre important de ces personnes âgées font l'expérience de problèmes en lien avec l'utilisation de leur fauteuil roulant. Afin de pouvoir démontrer la qualité des produits, des services et des interventions dans le domaine des aides techniques, il importe d'en mesurer les résultats. La satisfaction des usagers est le but ultime recherché par l'ensemble des partenaires impliqués dans le processus d'attribution des aides techniques. Toutefois, peu d'instruments de mesure spécifiques, valides et fidèles sont disponibles pour mesurer la satisfaction des usagers envers leur aide technique. La satisfaction des personnes âgées hébergées envers leur fauteuil roulant demeure donc encore inconnue ainsi que les caractéristiques des utilisateurs, de l'aide technique et de l'environnement influençant leur degré de satisfaction. Cette étude a été réalisée dans le cadre des activités de la Chaire industrielle du Conseil de la Recherche en Science Naturelle et en Génie (CRSNG) sur les aides techniques à la posture de l'École Polytechnique de Montréal. Son but était d'évaluer la satisfaction des personnes âgées vivant en institution envers leur fauteuil roulant et d'identifier si leur degré de satisfaction est influencé par leur niveau d'indépendance fonctionnelle. L'Évaluation de la Satisfaction envers une Aide Technique (ÉSAT) a donc été utilisée afin de répondre à quatre questions de recherche. Ces questions avaient comme objectif d'identifier les degrés d'importance et de satisfaction accordés par les personnes âgées aux variables de l'ÉSAT en regard de leur fauteuil roulant, de déterminer les caractéristiques des sujets et du fauteuil roulant influençant leur degré satisfaction ainsi que de vérifier la relation existant entre l'indépendance fonctionnelle des personnes âgées hébergées et leur satisfaction envers leur fauteuil roulant. Trente-deux sujets ont été recrutés au sein de trois établissements de soins de longue durée de la région de Montréal. Deux instruments de mesure ont été employés lors de la collecte de données : la Mesure de l'Indépendance Fonctionnelle (MIF) et I'ÉSAT. Des informations sur le niveau d'indépendance fonctionnelle, sur les caractéristiques des sujets et de leur fauteuil roulant ainsi que sur les degrés d'importance et de satisfaction accordés aux 24 variables de l'ESAT ont été recueillies. Les résultats ont démontré que les variables les plus importantes étaient la durabilité, le confort, le service professionnel, la polyvalence et le suivi des services c’est alors que les moins importantes étaient la réaction des autres, l’apparence, le poids, l'entraînement et le soutien de l'entourage. Les variables les plus satisfaisantes étaient la facilité d'utilisation, le service professionnel, la sécurité, l’apparence et l’efficacité alors que les moins satisfaisantes étaient les ajustements, le confort, le suivi des services, le poids et les dimensions. L'âge et le type de fauteuil roulant (manuel ou motorisé) étaient tes caractéristiques les plus susceptibles d'avoir un impact sur la satisfaction des usagers. Les sujets plus âgés et ceux utilisant un fauteuil roulant manuel étaient généralement plus satisfaits de leur fauteuil roulant. De plus, une relation positive entre le niveau d'indépendance fonctionnelle et la satisfaction a été identifiée. L'indépendance fonctionnelle permettait d'expliquer 15% de la variation entre la satisfaction des sujets. Ainsi, les sujets ayant un plus haut niveau d'indépendance fonctionnelle était habituellement plus satisfaits de leur fauteuil roulant. Cette étude exploratoire a favorisé l'acquisition d'une meilleure connaissance de la clientèle âgée vivant en institution envers leur fauteuil roulant. Malgré certaines limites, elle présente plusieurs recommandations pertinentes ainsi que des pistes recherches futures pour la mesure des résultats des aides techniques et pour l'amélioration de la satisfaction des personnes âgées vivant en institution envers leur fauteuil roulant.

The classical populist theories are not enough to analyze such phenomena, though we combine with it developmentist theory in order to clarify the meaning. The basic sources for this work was reports, letters, memorandum, and other documents produced by Secretaria de Estado das Relações Exteriores during Juscelino Kubitschek government / O núcleo das preocupações teóricas desta dissertação é analisar sob o prisma do populismo-desenvolvimentista o Brasil no processo de rompimento com o Fundo Monetário Internacional. As clássicas teses de perspectivas populistas demonstraram insuficiências em seus alguns de seus apontamentos. Desta forma, conciliamos à leitura populista as perspectivas desenvolvimentistas do período com o intuito de uma abordagem mais contemplativa sobre o período. Nesta tentativa, analisamos o processo de rompimento desta luz teórica, os nossos subsídios empíricos. Fazem parte do corpo documental, relatórios, cartas, ofícios que obtivemos na Secretaria de Estado das Relações Exteriores. No primeiro capítulo, discorremos sobre o processo de implementação do desenvolvimento acelerado do Plano de Metas de Juscelino Kubitschek. No segundo capítulo, abordamos as conseqüências deste modelo de desenvolvimento para os desentendimentos com o FMI. No terceiro e último capítulo, problematizamos os efeitos, causas e resultados do processo de rompimento com o FMI

Atualmente no Brasil, crescem em importância os estudos sobre cuidados domiciliários à saúde de pessoas com perdas funcionais e dependência e seus cuidadores, em razão das transições demográfica e epidemiológica do país. Na Atenção Básica, com a implementação do Programa Saúde da Família (PSF), o cadastramento das famílias feito pelos agentes comunitários de saúde tornou visíveis as necessidades de saúde desses pacientes, antes confinados a seus lares, e de seus cuidadores. Este estudo teve como objetivo avaliar a qualidade de vida de cuidadores familiares de pacientes com perdas funcionais e dependência, atendidos por equipes de saúde da família, relacionando-a a características sociodemográficas, condições de saúde, grau de sobrecarga percebida e o grau de independência funcional do paciente. Foram entrevistados 66 cuidadores familiares atendidos por equipes de PSF na região sul do município de São Paulo. Os instrumentos utilizados foram: 1) caracterização do cuidador familiar e do paciente; 2) WHOQOL-bref, para avaliação de qualidade de vida subjetiva; 3) Zarit Burden Interview (ZBI), para avaliação da sobrecarga do cuidador, e 4) Escala de Medida de Independência Funcional (MIF), para avaliação da capacidade funcional dos pacientes. Os cuidadores eram, em sua maioria, mulheres (83,3%), casadas (62,2%) com média de idade de 50,5 anos. Na condição de filhas ou filhos (37,9%) e esposas ou esposos (24,2%), cuidavam de pacientes com até 50% de dependência para atividades básicas da vida diária (MIF total = 57,82) e estavam moderadamente sobrecarregados (Zarit total = 32,12). Apresentaram melhor escore de qualidade de vida no domínio físico (66,72) e pior no domínio meio ambiente (52,51). A escala de sobrecarga, a presença de companheiro e a presença de doença no cuidador mostraram-se estatisticamente relacionadas à ´qualidade e vida geral´, no modelo de regressão múltipla final. Os resultados permitiram concluir que a qualidade de vida do cuidador correlacionou-se estatisticamente à sobrecarga percebida, indicando que quanto menores os escores em todos os domínios do WHOQOL-bref, maior a sobrecarga. Não houve associação estatística significativa entre o grau de independência funcional e a qualidade de vida do cuidador. Políticas públicas efetivas, destinadas a oferecer uma rede de serviços de suporte às famílias de pessoas com perdas funcionais e dependência, são primordiais para a diminuição da sobrecarga do cuidador e conseqüente melhora da sua qualidade de vida e de seus familiares / In Brazil, the study of home health care of people with disabilities and dependency and their caregivers is growing in importance due to demographic and epidemiological changes in the country. With the introduction of the Family Health Program, the registration of families in Primary Care by community health agents brought to light the health needs of these patients, who were previously confined to their homes and to their caregivers. The objective of this study was to evaluate the quality of life of family caregivers of patients with disabilities and dependency, served by family healthcare teams, in terms of socio-demographic characteristics, health conditions, level of perceived burden and degree of functional independence of the patient. Family Health Care Program teams interviewed 66 family caregivers in the southern region of the city of São Paulo. The tools employed were: 1) characterization of the family caregiver and patient; 2) WHOQOL-bref, for the subjective evaluation of quality of life; 3) Zarit Burden Interview (ZBI), to evaluate caregiver burden, and 4) Functional Independence Measure Scale (FIM), to evaluate the functional capacity of patients. The caregivers were mostly women (83.3%), married (62.2%) with an average age of 50.5 years. Caregivers were daughters (37.9%) and spouses (24.2%), who cared for patients with up to 50% dependence for instrumental activities of daily living (MIF total = 57.82) and were moderately burdened (Zarit total = 32.12). The physical domain received the best quality of life score (66.72) and the worst score went to the environment domain (52.51). The amount of burden, presence of companion and presence of caregiver illness were statistically associated with general quality of life in the final multiple regression model. The results showed that caregiver quality of life is statistically correlated with perceived burden, indicating that the lower the score in all WHOQOL-bref domains, the higher the burden. No significant statistical association between degree of functional independence and caregiver quality of life was found. Effective public policies designed to offer a network of support services for families of people with dependence and functional loss are essential to reduce the burden placed on caregivers and consequently improve quality of life for them and their families
