This report argues that historic landscape preservation efforts need to embrace biodiversity planning. Historic landscape preservation sites need to develop biodiversity plans because they are uniquely qualified to provide the continuous monitoring that successful biodiversity planning requires. Not only will biodiversity monitoring at various historic landscape sites contribute to a nationwide collection of biodiversity planning data, but it will also provide a rich source of information that can be presented to draw a wider audience into the biodiversity discussion. After considering three precedents: Old Sturbridge Village, Old World Wisconsin, and Tucson Botanical Gardens, the report focuses on the Kino Heritage Fruit Trees Project and its real and potential impacts on biodiversity planning in southern Arizona and more broadly. Finally, the report considers how seed libraries and seed swaps might serve a similar purpose in other parts of the country. / text

In 1988, Galle Fort in Sri Lanka was declared a world heritage site by UNESCO. The new historic-preservation regulatory setup that came with this designation displaced its inhabitants in their own homes. This thesis examines on how these inhabitants negotiate preservation regulations and the government’s effort to maintain a “world heritage” status based on their view. It focuses on how people adapt to the newly regulated environment and create spaces for their own daily practices. This study identifies that there are people who follow the government rules and transform themselves into subjects, while others break government rules and create the lived spaces they want. In-between are the majority of people who both become subjects of the space and also negotiate with the government rules to create their (negotiated) living environments. Although the government has more power, the people with less power have been transforming the space to meet their own needs and create a sense of place. / Department of Urban Planning

INTRODUÇÃO: O transplante traqueal continua um desafio. Contudo, avanços nas técnicas de revascularização dos enxertos traqueais e no conhecimento da imunobiologia da traquéia, indicam que esta técnica pode ser utilizada com freqüência no futuro próximo. A depuração mucociliar (DM) é o mecanismo de defesa inato mais importante das vias aéreas. A traquéia age como um órgão de defesa devido à DM. A DM ocorre por ação do batimento ciliar do epitélio respiratório que impele o muco que atapeta as vias respiratórias, carreando substâncias nocivas. Idealmente, a DM deve ser preservada em enxertos traqueais passíveis de utilização para transplante traqueal. Nosso intuito foi: 1) avaliar os efeitos da isquemia fria sobre a DM; e 2) avaliar a ação de soluções de preservação administradas por via tópica na manutenção da DM após isquemia fria. MÉTODOS: De 109 ratos Wistar foram obtidos 217 segmentos traqueais. Os segmentos foram distribuídos entre três grupos experimentais e um grupo Controle. Cada segmento foi submergido em LPD-glicose (grupo LPD), histidina-triptofano-cetoglutarato (grupo HTK) ou solução salina (grupo Salina). Avaliou-se a DM após 6,10,16 ou 24 horas de isquemia fria. No grupo Controle os segmentos foram analisados imediatamente após a extração, não havendo isquemia fria, nem submersão em soluções. A velocidade de transporte mucociliar (VTM) foi medida através de microscópio de luz, pela observação do movimento das partículas de muco na superfície dos segmentos traqueais. A freqüência de batimento ciliar (FBC) foi obtida pela sincronização entre o movimento ciliar observado pelo microscópio de luz e um estroboscópio. Em seguida, os segmentos foram corados com hematoxilina-eosina para analisar a integridade epitelial (IE) e a inflamação subepitelial (IS). Foi realizada análise quantitativa do muco intracelular por um programa de computador após coloração com azul de alcião (MI-AA) e PAS (MI-PAS). As amostras mais significativas foram analisadas qualitativamente por microscopia eletrônica de transmissão (ME). Foram realizadas duas análises: 1) grupo Controle e tempos de isquemia; e 2) grupo Controle e soluções de preservação (agrupado pelo tempo de isquemia). RESULTADOS: 1) grupo Controle e tempos de isquemia: O grupo controle foi melhor que os grupos submetidos a isquemia fria quanto à VTM (p=0,0001) e FBC (p=0,012). Contudo, não houve diferença na IE, IS e MI entre o grupo Controle e os demais grupos. 2) grupo Controle e soluções de preservação: O grupo controle apresentou melhor VTM que os grupos LPD, HTK e Salina após isquemia de 6h (p=0,001), 16h (p=0,009) e 24h (p=0,001). O grupo controle apresentou melhor FBC que os grupos LPD, HTK e Salina após isquemia de 24h (p=0,001). Não houve diferença entre os grupos na IE e IS. O grupo Controle apresentou melhor MI-AA que os grupos LPD após 16h (p=0,02) e HTK após 24h de isquemia (p=0,04). Não houve diferença entre os grupos à MI-PAS. À ME, o grupo Salina apresentou maiores alterações secundárias à isquemia do que os demais grupos. CONCLUSÕES: 1) A isquemia fria piora a DM; e 2) O uso de soluções de preservação administradas por via tópica não contribui para manutenção da DM após isquemia fria / INTRODUCTION: Tracheal transplantation is a challenging problem. Recent advances in graft revascularization, and reepithelialization renewed the interest on airway transplantation. Mucociliary clearance (MC) is the most important innate defense mechanism of the respiratory system. MC works by mucous transport carried out by ciliary beating function of the airway epithelium. Trachea acts as a defense organ in the respiratory system through the MC. Ideally, MC should be preserved in tracheal grafts used for transplantation. Preservation solutions improve organ preservation by decreasing ischemic injury. The purpose of the study was: 1) to evaluate the effects of cold ischemia on MC; and 2) to evaluate the impact of topically-applied preservation solutions on MC after cold ischemia. METHODS: From 109 male Wistar rats we obtained 217 tracheal segments. The segments were allocated to one of four groups. Segments were submerged in LPD-glucose (LPD group), histidine-tryptophan-ketoglutarate (HTK group), or saline solution (Saline group), and stored at 4C. MC was analyzed after 6, 10, 16 or 24h of ischemia. Control group have only segments that were analyzed right after extraction, not submitted to cold ischemia or submersion in preservation solutions. The mucociliary transport velocity (MTV) was measured by observation of mucous particle under the surface of the segments, through a light microscope. Ciliary beating frequency (CBF) was achieved by synchronization between cilia movement and a stroboscope flashlight. Tracheas were stained with hematoxylin-eosin in order to analyze the epithelial integrity (EI) and the subepithelial inflammation (SI). A quantitative analysis of the intracellular mucus stained with alcian blue (IM -AB) and PAS (IM-PAS) was achieved by a software. The most significant samples of the tracheal segments were qualitatively analyzed by transmission electronic microscopy (TEM). Two analyses were made: 1) Control group and ischemic time; and 2) Control group and preservation solutions. RESULTS: 1) Control group and ischemic time: Control group had better VTM (p=0,0001) and CBF (p=0,012) than the groups submitted to cold ischemia. However, there was no difference among Control group and the other groups on EI, SI, IM-AB, and IM-PAS. 2) Control group and preservation solutions: Control group showed better MTV than the LPD, HTK, and Saline groups after 6h (p=0,001), 16h (p=0,009) and 24h (p=0,001) of cold ischemia. Control group showed better CBF than the LPD, HTK, and Saline groups after 24h of ischemia (p=0,001). There was no difference among groups on EI and SI. Control group showed better IM-AB than both the LPD group after 16h of cold ischemia (p=0,02), and the HTK group after 24h of cold ischemia (p=0,04). There was no difference among the groups on IM-PAS. TEM showed more findings of ischemic lesion on Saline group. CONCLUSIONS: 1) Cold ischemia impairs MC; and 2) Topically-applied preservation solutions do not ameliorate MC after cold ischemia

INTRODUÇÃO: A lesão de isquemia-reperfusão continua sendo considerada a maior causa de mortalidade relacionada ao transplante de pulmão e sua gravidade é influenciada por diversos fatores, dentre eles, a preservação pulmonar. OBJETIVO: Comparar duas soluções de preservação pulmonar, Perfadex® e Celsior®, quanto a capacidade de preservação de tecido pulmonar isquêmico. MÉTODOS: Sessenta pulmões de ratos preservados com Perfadex®, Celsior® ou solução salina após períodos de isquemia hipotérmica de 6 ou 12 horas, foram reperfundidos com sangue homólogo em modelo experimental ex-vivo durante 60 minutos consecutivos. A cada 10 minutos os dados de gasometria, hematócrito, mecânica ventilatória, hemodinâmica e peso do bloco cardiopulmonar foram registrados. Ao final da reperfusão o pulmão esquerdo foi pesado e acondicionado por 48h a 70oC para obtenção da razão peso úmido/peso seco, bem como amostras de tecido pulmonar foram retiradas para histopatologia, microscopia eletrônica e TUNEL. A análise estatística incluiu a comparação entre as soluções e os tempos de isquemia, utilizando ANOVA e Kruskall-Wallis. O nível de significância foi de 5%. RESULTADOS: A comparação entre as complacências de pulmões preservados com Celsior® e Perfadex® nos tempos de isquemia de 6 e 12 horas não apresentou significância estatística (p=0,161 e p=0,316, respectivamente). Os pulmões submetidos a 6 horas de isquemia apresentaram complacência pulmonar superior aos de 12 horas (Perfadex® p=0,02; Celsior® p=0,019; Salina p=0,016). Os valores de pressão arterial pulmonar foram semelhantes entre as três soluções nos dois tempos de isquemia, bem como na comparação entre os tempos de 6 e 12 horas, independente da solução. A Capacidade Relativa de Oxigenação não demonstrou diferença estatística entre as três soluções, independentemente do tempo de isquemia. Na comparação entre os dois tempos de isquemia, o desempenho da oxigenação foi significativamente pior nos pulmões preservados com salina por 12 horas (p=0,001). A razão peso úmido/peso seco não apresentou diferença estatística significante entre as três soluções nos dois tempos de isquemia, porém na comparação entre os tempos de isquemia, os pulmões preservados com Perfadex® apresentaram uma relação peso úmido/peso seco maior no tempo de isquemia mais longo (p=0,001). À microscopia óptica, pulmões preservados com salina apresentaram mais edema que os demais, independentemente do tempo de isquemia. A avaliação da apoptose celular através do método de TUNEL não mostrou diferença estatisticamente significativa na comparação entre os grupos. CONCLUSÃO: Os pulmões preservados com Perfadex® e Celsior® apresentaram desempenho similar em relação às trocas gasosas e parâmetros hemodinâmicos e de mecânica ventilatória. Os pulmões preservados com Perfadex® por 12 horas apresentaram mais edema. Os achados histopatológicos não diferiram entre os grupos estudados / INTRODUCTION: Ischemia-reperfusion injury remaisn the leading cause of mortality related to lung transplantation. Its severity is influenced by several factors including lung preservation. OBJECTIVE: To compare two lung preservation solutions, Perfadex® and Celsior® and its ability to preserve ischemic lung tissue. METHODS: Sixty rat lungs were preserved with Perfadex®, Celsior® or saline after a cold ischemic period of 6 or 12 hours and were then reperfused with homologous blood in an ex vivo experimental model for 60 consecutive minutes. At 10-minute intervals during reperfusion of the heart-lung blocks, data were collected for blood gases, hematocrit, mechanical ventilation, hemodynamic and the heart-lung block weight was recorded. At the end of reperfusion, the left lung was weighed and packaged kept at 70oC for 48h to obtain the wet-to-dry weight ratio. Lung tissue samples were processed for histology, electron microscopy and TUNEL. Statistical analysis included a comparison of the solutions and ischemic times, using ANOVA and Kruskal-Wallis. The significance level was set at 5%. RESULTS: The comparison between the compliance of lungs preserved with Celsior® and Perfadex® in ischemic times of 6 and 12 hours was not statistically significant (p=0.161 and p=0.316, respectively). The lungs subjected to 6 hours of ischemia showed higher lung compliance compared to 12 hours (p=0.02 Perfadex®; Celsior® p=0.019; saline p=0.016). The pulmonary artery pressure values were similar between the three solutions in two stages of ischemia and comparing the times of 6 and 12 hours, regardless of the solution. The Relative Oxygenation Capacity showed no significant difference between the three solutions tested, regardless of the ischemic time. The comparison between the two ischemic times showed that oxygenation capacity was significantly worse in lungs preserved with saline for 12 hours (p=0.001). The wet-to-dry weight ratio showed no statistically significant difference between the three solutions in both ischemic times. However, when ischemic times were compared, Perfadex® showed greater wet-to-dry weight ratio in lungs submitted to 12 hours of ischemia (p=0.001). Light microscopy showed that lungs preserved with saline had more edema than the others, regardless of the ischemic time. Assessment of apoptosis by the TUNEL assay showed no statistically significant difference in the comparison between the groups. CONCLUSIONS: The lungs preserved with Celsior® and Perfadex® performed evenly in regards to gas exchange, hemodynamics and ventilatory mechanics. The lungs preserved with Perfadex® for 12 hours were more edematous. Histopathology findings did not differ between the groups

The preservation of graft is the cornerstone for the OLT with cadaveric donor. In this context, it is important to evaluate the effectiveness of different solutions used for it. Our objective was to compare the results of OLT, carried out with cadaveric donor, preserved with the solutions of preservation ViaSpan® or Celsior®. Casuistic and Method: we evaluated retrospectively 72 recipients of the OLT. Of these, 36 had their graft preserved with ViaSpanâ solution (Group A) and 36 with Celsiorâ solution (Group B) as follows: the donor was perfused in situ of 1000 ml in the portal vein of ViaSpanâ or Celsiorâ and 3000 ml of Euro-Collins in aortic artery; in the table managed ViaSpanâ or Celsiorâ 500 ml in the portal vein, 250 ml in hepatic artery and 250 ml in the biliary duct. The following variables in groups A and B were evaluated: cost of the solutions, characteristics of the donors, characteristics of the recipients, intraoperative details, reperfusion injury and esteatose of graft with biopsy carried out after the reperfusion. As results of the OLT were evaluated: grafts with primary nonfunction (PNF), initial poor function (IPF), rejection, complications of the biliary duct, complications of the hepatic artery, retransplantation, follow up of the receiver in the first year after the OLT. Results: bigger warm ischemia and duration of surgery in group A (p= 0,002 and 0.001 respectively). The cost of the Celsior solution was lower (less than U$ 266.00 per litre). The remaining: characteristics of the donors, characteristics of the recipients, reperfusion injury, steatosis, PNF, PDF, rejection, retransplantation and recipients survival had not shown significant difference in statistics. Stenosis of the biliary duct was 3 cases (8.3%) in group A and 8 (22.2%) in group B (p= 0.19) and thrombosis of the hepatic artery were 4 cases (11.1%) in group B and none in group A (p= 0.11). Conclusion: the result of OLT, performed with cadaveric donor, preserved with ViaSpanâ or Celsiorâ solutions was similar. However we observe a trend of bigger number of stenosis of the biliary duct and thrombosis of the hepatic artery in the recipients of agencies preserved with the Celsiorâ solution. Thus, we believe that more research is necessary to clarify this relation. / O transplante de fígado (TxF) é hoje o padrão ouro para o tratamento da doença hepática terminal. A preservação do enxerto é a pedra fundamental para o TxF com doador cadáver. Nesse contexto, é importante avaliar a eficácia das diferentes soluções de preservação. Nosso objetivo foi comparar os resultados de TxF, realizados com órgãos de doadores cadáver, preservados com as soluções de preservação ViaSpan® ou Celsior®. Casuística e Método: Avaliamos retrospectivamente 72 pacientes submetidos a TxF. Desses, 36 tiveram seus enxertos preservados com a solução ViaSpan (Grupo A) e 36 com Celsior (Grupo B) da seguinte forma: perfusão in situ de 1000 ml na veia porta de ViaSpan ou Celsior e 3000 ml de Euro-Collins na aorta; e na mesa administrou-se 500 ml de ViaSpan ou Celsior na veia porta, 250 ml na artéria hepática e 250 ml na via biliar. Avaliamos as seguintes variáveis nos grupos A e B: custo das soluções, dados dos doadores, dados dos receptores, dados do intra-operatório, lesão de preservação e esteatose do enxerto com biópsia realizada após a reperfusão. Como resultado do TxF avaliamos: falência primária (FPE) e disfunção primária do enxerto (DPE), rejeição, complicações da via biliar, complicações da artéria hepática, retransplante, sobrevida do receptor no primeiro ano de pós-transplante. Resultados: O tempo de isquemia quente e tempo cirúrgico maiores no grupo A (p= 0,002 e 0,001 respectivamente). O custo da solução Celsior foi menor (R$ 400,00 a menos por litro). O restante dos dados dos doadores, dados dos receptores, lesão de preservação e esteatose do enxerto com biópsia realizada após a reperfusão, FPE e DPE, retransplante, sobrevida do receptor não mostraram diferença estatística. A estenose da via biliar foi de 3 (8,3%) casos no grupo A e 8 (22,2%) no grupo B (p= 0,19) e a trombose da artéria hepática foi 4 (11,1%) casos no grupo B e ausente no grupo A (p= 0,11). Conclusão: O resultado de TxF, realizado com doador cadáver, preservado com as soluções ViaSpan® ou Celsior® foi similar. Contudo observamos um maior número de estenose de via biliar e trombose arterial nos receptores de órgãos preservados com a solução Celsior. Assim, acreditamos que sejam necessários novos trabalhos para esclarecer esta relação.
