Histopatologia da leishmaniose tegumentar por Leishmania braziliensis braziliensis: 4. Classificação histopatológica

Os A A. analisaram as alterações histológicas encontradas em 162 casos de Leishmaniose Tegumentar da localidade de Três Braços, Estado da Bahia, dos quais 131 (80,9%) eram de portadores de lesões cutâneas e 31 (19,1%) de portadores de lesões mucosas. Analisaram, também, o comportamento clínico dos cinco padrões histopatológicos, já antes descritos, em relação à terapêutica. O melhor prognóstico esteve sempre ligado ao padrão de Reação Exsudativa e Granulomatosa, ou seja, a uma fase na qual o organismo, tendo lançado mão de um mecanismo endógeno de lise parasitária, já circunscreveu a área de necrose por uma reação granulomatosa, e esta é agora apenas o elemento residual. A ação terapêutica nessa fase somente acelera a resolução natural do caso. O grupo seguinte é amplo, e compreende os casos em que a lesão pertence aos padrões de Reação Exsudativa Celular (formas cutâneas), Reação Exsudativa e Necrótica e Reação Exsudativa e Necrótico-Granulomatosa. Nesses casos, o mecanismo de auto-controle da lesão encontra-se ainda em curso, e a ação terapêutica encurta o período de evolução natural. Os f.asos do padrão de Reação Exsudativa e Tuberculóide tiveram um prognóstico variável. Houve boa resposta à terapêutica quando o granuloma tuberculóide característico desse padrão surgiu em pacientes jovens, com curto tempo de evolução da doença e intradermorreação não exacerbada. Nos demais casos tuberculóides —. principalmente em pacientes adultos, com longo tempo de evolução da doença e intradermorreação exacerbada —, a resposta foi menos satisfatória. Em último lugar, com prognóstico reservado, ficaram os casos da forma mucosa que apresentaram o padrão de Reação Exsudativa Celular, onde o infiltrado pode estar desempenhando papel de auto-agressão. O presente estudo evoluiu para a proposição de uma classificação da Leishmaniose Tegumentar, baseada nos padrões histopatológicos observados. Esta classificação, estritamente morfológica, deverá ser de fácil aplicação para o Patologista e, como apresenta também uma correspondência clínico-evolutiva poderá constituir auxílio valioso ao médico envolvido no diagnóstico e tratamento da Leishmaniose Tegumentar.

Synthesis of Short Oligonucleotides on a Soluble Support by the Phosphoramidite Method

In the last decades, the chemical synthesis of short oligonucleotides has become an important aspect of study due to the discovery of new functions for nucleic acids such as antisense oligonucleotides (ASOs), aptamers, DNAzymes, microRNA (miRNA) and small interfering RNA (siRNA). The applications in modern therapies and fundamental medicine on the treatment of different cancer diseases, viral infections and genetic disorders has established the necessity to develop scalable methods for their cheaper and easier industrial manufacture. While small scale solid-phase oligonucleotide synthesis is the method of choice in the field, various challenges still remain associated with the production of short DNA and RNA-oligomers in very large quantities. On the other hand, solution phase synthesis of oligonucleotides offers a more predictable scaling-up of the synthesis and is amenable to standard industrial manufacture techniques. In the present thesis, various protocols for the synthesis of short DNA and RNA oligomers have been studied on a peracetylated and methylated β-cyclodextrin, and also on a pentaerythritol-derived support. On using the peracetylated and methylated β-cyclodextrin soluble supports, the coupling cycle was simplified by replacement of the typical 5′-O-(4,4′-dimethoxytrityl) protecting group with an acid-labile acetal-protected 5′-O-(1-methoxy-1-methylethyl) group, which upon acid-catalyzed methanolysis released easily removable volatile products. For this reason monomeric building blocks 5′-O-(1-methoxy-1-methylethyl) 3′-(2-cyano-ethyl-N,N-diisopropylphosphoramidite) were synthesized. Alternatively, on using the precipitative pentaerythritol support, novel 2´-O-(2-cyanoethyl)-5´-O-(1-methoxy-1-methylethyl) protected phosphoramidite building blocks for RNA synthesis have been prepared and their applicability by the synthesis of a pentamer was demonstrated. Similarly, a method for the preparation of short RNAs from commercially available 5´-O-(4,4´-dimethoxytrityl)-2´-O-(tert-butyldimethyl-silyl)ribonucleoside 3´-(2-cyanoethyl-N,N-diisopropylphosphoramidite) building blocks has been developed

Combined systemic and local morpholino treatment rescues the phenotype of the SMA Delta 7 mouse model

Spinal muscular atrophy (SMA) is a childhood fatal motor neuron disease caused by mutations in the Survival Motor Neuron 1 (SMN1) gene, currently without effective treatment. One possible therapeutic approach is the use of antisense oligonucleotides (ASOs) to redirect the splicing of a paralogous gene, SMN2, to increase the production of functional SMN protein. A range of ASOs with different chemical properties is suitable for these applications, including a morpholino (MO) variant, which has a particularly excellent safety, and efficacy profile. We used a 25- nt MO oligomer sequence against the ISS-N1 region of SMN2 (HSMN2Ex7D(-10-34)) with superior efficacy to previously described sequences also in transgenic SMA Δ7 mice. The combined local and systemic administration of MO (bare or conjugated to octa-guanidine) is necessary to increase full-length SMN expression, leading to robust neuropathological features improvement and survival rescue. Additionally, several snRNA levels that are dysregulated in SMA mice could be restored by MO treatment. These results demonstrate that MO therapy is efficacious and can result in phenotypic rescue. These data provide important insights for the development of therapeutic strategies in SMA patients.

Effect of Combined Systemic and Local Morpholino Treatment on the Spinal Muscular Atrophy Δ7 Mouse Model Phenotype

BACKGROUND: Spinal muscular atrophy (SMA) is a fatal motor neuron disease of childhood that is caused by mutations in the SMN1 gene. Currently, no effective treatment is available. One possible therapeutic approach is the use of antisense oligos (ASOs) to redirect the splicing of the paralogous gene SMN2, thus increasing functional SMN protein production. Various ASOs with different chemical properties are suitable for these applications, including a morpholino oligomer (MO) variant with a particularly excellent safety and efficacy profile. OBJECTIVE: We investigated a 25-nt MO sequence targeting the negative intronic splicing silencer (ISS-N1) 10 to 34 region. METHODS: We administered a 25-nt MO sequence against the ISS-N1 region of SMN2 (HSMN2Ex7D[-10-34]) in the SMAΔ7 mouse model and evaluated the effect and neuropathologic phenotype. We tested different concentrations (from 2 to 24 nM) and delivery protocols (intracerebroventricular injection, systemic injection, or both). We evaluated the treatment efficacy regarding SMN levels, survival, neuromuscular phenotype, and neuropathologic features. RESULTS: We found that a 25-nt MO sequence against the ISS-N1 region of SMN2 (HSMN2Ex7D[-10-34]) exhibited superior efficacy in transgenic SMAΔ7 mice compared with previously described sequences. In our experiments, the combination of local and systemic administration of MO (bare or conjugated to octaguanidine) was the most effective approach for increasing full-length SMN expression, leading to robust improvement in neuropathologic features and survival. Moreover, we found that several small nuclear RNAs were deregulated in SMA mice and that their levels were restored by MO treatment. CONCLUSION: These results indicate that MO-mediated SMA therapy is efficacious and can result in phenotypic rescue, providing important insights for further development of ASO-based therapeutic strategies in SMA patients.

Self-assembly into nanoparticles is essential for receptor mediated uptake of therapeutic antisense oligonucleotides

Antisense oligonucleotides (ASOs) have the potential of revolutionizing medicine due to their ability to manipulate gene function for therapeutic purposes. ASOs are chemically modified and/or incorporated with nanoparticles to enhance their stability and cellular uptake; however, one of the biggest challenges is the poor understanding of their uptake mechanism, which is needed for designing better ASOs with high activity and low toxicity. Here, we study the uptake mechanism of three therapeutically relevant ASOs (peptide-conjugated phosphorodiamidate morpholino (P-PMO), 2?Omethyl phosphorothioate (2?OMe) and phosphorothioated tricyclo DNA (tcDNA) that have been optimized to induce exon skipping in models of Deuchenne muscular dystrophy (DMD). We show that P-PMO and tcDNA have high propensity to spontaneously self-assemble into nanoparticles. P-PMO forms micelles of defined size and their net charge (zeta potential) is dependent on the medium and concentration. In biomimetic conditions and at low concentrations P-PMO obtains net negative charge and its uptake is mediated by class A scavenger receptor subtypes (SCARAs) as shown by competitive inhibition and RNAi silencing experiments in-vitro. In-vivo, the activity of P-PMO was significantly decreased in SCARA1 knock-out mice compared to wild-type animals. Additionally, we show that SCARA1 is involved in the uptake of tcDNA and 2?OMe as shown by competitive inhibition and co-localization experiments. Surface plasmon resonance binding analysis to SCARA1 demonstrated that P-PMO and tcDNA have higher binding profiles to the receptor compared to 2?OMe. These results demonstrate receptor-mediated uptake for a range of ASO chemistries, a mechanism that is dependent on their self-assembly into nanoparticles.

Alternative service organizations: Funding environment, strategies, and patterns of adaptation

This study explored the strategies that community-based, consumer-focused advocacy, alternative service organizations (ASOs), implemented to adapt to the changes in the nonprofit funding environment (Oliver & McShane, 1979; Perlmutter, 1988a, 1994). It is not clear as to the extent to which current funding trends have influenced ASOs as little empirical research has been conducted in this area (Magnus, 2001; Marquez, 2003; Powell, 1986). ^ This study used a qualitative research design to investigate strategies implemented by these organizations to adapt to changes such as decreasing government, foundation, and corporate funding and an increasing number of nonprofit organizations. More than 20 community informants helped to identify, locate, and provide information about ASOs. Semi-structured interviews were conducted with a sample of 30 ASO executive directors from diverse organizations in Miami-bade and Broward Counties, in South Florida. ^ Data analysis was facilitated by the use of ATLAS.ti, version 5, a qualitative data analysis computer software program designed for grounded theory research. This process generated five major themes: Funding Environment; Internal Structure; Strategies for Survival; Sustainability; and Committing to the Cause, Mission, and Vision. ^ The results indicate that ASOs are struggling to survive financially by cutting programs, decreasing staff, and limiting service to consumers. They are also exploring ways to develop fundraising strategies; for example, increasing the number of proposals written for grants, focusing on fund development, and establishing for-profit ventures. Even organizations that state that they are currently financially stable are concerned about their financial vulnerability. There is little flexibility or cushioning to adjust to "funding jolts." The fear of losing current funding levels and being placed in a tenuous financial situation is a constant concern for these ASOs. ^ Further data collected from the self-administered Funding Checklist and demographic forms were coded and analyzed using Statistical Package for the Social Sciences (SPSS). Descriptive information and frequencies generated findings regarding the revenue, staff compliment, use of volunteers and fundraising consultants, and fundraising practices. The study proposes a model of funding relationships and presents implications for social work practice, and policy, along with recommendations for future research. ^

Historical analysis of two contemporary issues at the International Community School of Abidjan, Cote d'Ivoire: Local -hired and overseas -hired teacher relationships. Community perceptions of the U.S. Embassy at ICSA

This study was a qualitative investigation to ascertain and describe two of the current issues at the International Community School of Abidjan, examine their historical bases, and analyze their impact on the school environment.^ Two issues emerged during the inquiry phase of this study: (1) the relationship between local-hired and overseas-hired teachers in light of the January 1994 devaluation which polarized the staff by negating a four-year salary scale that established equity, (2) the school community's wide variance in the perceived power that the U.S. Embassy has on school operations based on its role as ICSA's founding sponsor.^ A multiple studies approach was used in gathering data. An extensive examination of the school's archives was used to reconstruct an historical overview of ICSA. An initial questionnaire was distributed to teachers and administrators at an educational conference to determine the scope of the 1994 devaluation of the West and Central African CFA and its impact on school personnel in West African American-sponsored overseas schools (ASOS). Personal interviews were conducted with the school staff, administration, school board members, and relevant historical participants to determine the principal issues at ICSA at that time. The researcher, an overseas-hired teacher, also used participant observations to collect data. Findings based on these sources were used to analyze the two issues from an historical perspective and to form conclusions.^ Findings in this study pertaining to the events induced by the French and African governments' decision to implement a currency devaluation in January 1994 were presented in ex post-facto chronological narrative form to describe the events which transpired, describe the perception of school personnel involved in these events, examine the final resolution and interpret these events within a historical framework for analysis.^ The topic of the U.S. Embassy and its role at ICSA emerged inductively from open-ended personal interviews conducted over the course of a year. Contradictory perspectives were examined and researched for accuracy and cause. The results of this inquiry presented the U.S. Embassy role at ICSA from a two-sided perspective, examined the historical role of the Embassy, and presented means by which the role and responsibility of the U.S. Embassy could best be communicated to the school community.^ The final chapter provides specific actions for mediation of problems stemming from these issues, implications for administrators and teachers currently involved in overseas schools or considering the possibility, and suggestions for future inquiries.^ Examination of a two-tier salary scale for local-hired and overseas-hired teachers generated the following recommendations: movement towards a single salary scale when feasible, clearly stated personnel policies and full disclosure of benefits, a uniform certification standard, professional development programs and awareness of the impact of this issue on staff morale.^ Divergent perceptions and attitudes toward the role of the U.S. Embassy produced these recommendations: a view towards limiting the number of Americans on ASOS school boards, open school board meetings, selection of Embassy Administrative Officers who can educate school communities on the exact role of the Embassy, educating parents through the outreach activities that communicate American educational philosophy and involve all segments of the international community, and a firm effort on the part of the ASOS to establish the school's autonomy from special interests. ^

Playgrounds going wrong: study of the adult style and children's rights during recess in an early childhood and primary education center

Recent perspectives on Pedagogy for Early Childhood Education emphasize children's participation in line with the Children's Rights Convention. The study aimed to analyse how children's rights are dealt with during recess in a school (Early Childhood and Primary Education) in Portugal. The aims were: to characterize the style of the adult (teaching assistants) and the interactions that are established with the children at the playground/recess, and analyse them in terms of children's rights. The qualitative approach was based on the observation during the recess for three weeks. The Adult Style Observation Schedule for Early Childhood Education (ASOS-ECE) was used to register and code the dynamics of six teaching assistants (3 ECE and 3 PE). Critical incidents were also registered. Statistical analysis of the ASOS-ECE levels were complemented with the content analysis of the notes. The playground space was quite limited and affected children's play and well-being. The outdoor playground was never used for the Early Childhood classes, only for Primary Education students but with little supervision. Children were often deprived of playground time by decision of the teaching assistants, as punishment. The results obtained through the Adult Style Observation Schedule for Early Childhood Education (ASOS-ECE) are not satisfactory and are below what would meet the minimum quality value (3,5). For Early Childhood Education, sensibility is the most valued dimension but with very low levels (<2,5). For Primary Education it was autonomy that scored highest (<2,5). The analysis of the notes/critical incidents highlighted articles 12 (expression of own views), 13 (freedom of expression), 19 (protection against violence), 29 (development of personality) and 31 (rest and leisure, play and recreational activities) as being put into question by actions of the adults responsible for the children. Children's rights and well-being need to be put forward in the knowledge base for all adults working with children so that Pedagogy can fulfil its purpose fully.
