RESUMO O artigo abre o Dossiê Governança das Florestas Nativas discutindo os avanços alcançados pela governança florestal brasileira nos últimos 30 anos a partir de uma análise do Projeto Floram, das palestras apresentadas no “Web-Seminário Internacional Construindo Diálogos sobre Governança Florestal: Conservação, Manejo Sustentável e Restauração de Paisagens” e dos artigos que fazem parte do dossiê. Discute-se a passagem de modelos hierárquicos e centralizados para modelos de cogestão de sistemas socioecológicos florestais multiescalares, envolvendo uma diversidade maior de atores sociais públicos e privados, organizados em redes, que inovam a partir da co-construção de conhecimento, novas instituições e políticas públicas.

ABSTRACT The article opens the Native Forests Governance Dossier discussing advances in Brazilian forest governance in the last 30 years, based on an analysis of the Floram Project, on lectures presented at the “International Webinar Building Dialogues on Forest Governance: Conservation, Sustainable Management and Restoration of Landscapes,” and on the articles that are part of the dossier. The shift from hierarchical and centralized models to co-management models of multi-scale socio-ecological forest systems is discussed, involving a greater diversity of public and private social players, organized in networks, which innovate through the co-construction of knowledge, new institutions and public policies.

RESUMO Considerando o debate contemporâneo sobre as questões florestais, este artigo faz uma análise dos principais pontos comuns que foram destacados durante o Web-Seminário “Construindo Diálogos sobre Governança Florestal” e através dos artigos reunidos no Dossiê Governança florestal da revista Estudos Avançados do Instituto de Estudos Avançados da Universidade de São Paulo. Destacamos que a governança florestal se apresenta como um processo em constante evolução e deverá seguir promovendo a aproximação dos multiatores nos diversos níveis e escalas de decisão sobre as florestas e paisagens multifuncionais, e assim, fortalecer uma agenda de governança interdisciplinar e promotora de soluções com base nas melhores relações da sociedade com os sistemas socioecológicos.

ABSTRACT Considering the contemporary debate on forest issues, this article analyzes the main common points highlighted during the Webinar “Building Dialogues on Forest Governance” and in the articles of the Forest Governance Dossier of the Estudos Avançados journal of Institute of Advanced Studies of the University of São Paulo. We emphasize that forest governance is a process in constant evolution and should continue to help to bring together multiple stakeholders at different levels and scales of decision on forests and multifunctional landscapes, and thus, strengthen an interdisciplinary governance agenda that promotes solutions based on the best relations between society with socio-ecological systems.

Abstract Papillary intralymphatic angioendothelioma (Dabska tumor) is a rarely metastasizing lymphatic vascular neoplasm that usually affects children and young adults. The majority of these cases occur in soft tissues of extremities, and to date less than 40 cases have been described. Despite the generally indolent evolution, can be locally invasive with the potential to metastasize. We describe a case of a young woman presenting with a plantar lesion, for 9 months and histological diagnosis of Dabska tumor. This neoplasm should be considered in the differential diagnosis of vascular dermatoses, allowing early diagnosis and treatment. Long-term follow-up should be performed.

ABSTRACT It is essential for health care providers to be familiared with the full spectrum of clinical presentations of syphilis. We present herein a case of syphilide psoriasiforme, an uncommon but well recognized clinical presentation of secondary syphilis. A 46-year-old HIV-infected female patient was referred to our attention with a presumptive diagnosis of palmoplantar psoriasis. On examination, there were exuberant pinkish-red papules and plaques covered with a thick silvery scale in the palms, flexor surfaces of the wrists, and the medial longitudinal arches of the feet. Serological and histopathological analyses uncovered the diagnosis of syphilis. Clinical remission was obtained after treatment. A detailed review of the literature on syphilide psoriasiforme, including descriptions from older syphilology textsis provided. The present case report emphasizes the need for clinicians to have a heightened awareness of the varied and unusual clinical phenotypes of syphilis.

Resumo Os Conselhos Gestores são considerados instrumentos de gestão inovadores e importantes ao exercício da democracia no campo socioambiental. Este artigo buscou integrar a evolução dos marcos regulatórios dos Conselhos Gestores de Unidades de Conservação e a visão de servidores envolvidos nos processos de formulação das normas, a fim de compreender a trajetória de negociação desses processos. Os resultados mostram que a participação social está formalmente garantida em diversos aspectos das normas analisadas, o que representa uma conquista para a gestão ambiental mais democrática e inclusiva de Unidades de Conservação. Ainda assim, foram identificados paradoxos e desafios, relativos a aspectos de representatividade, independência, influência e compartilhamento genuíno de poder em processos de tomada de decisões. Os resultados sociais da participação pressupõem processos contínuos de aprendizagem e negociação, que se refletem no aprimoramento dos arranjos jurídicos analisados.

Abstract Management councils of Protected Areas are an important tool to the exercise of social participation of individuals and groups struggling for social-environmental causes in Brazil’s democracy. This paper aims to integrate the main regulations guiding the social participation in Management Councils of Protected Areas in Brazil and the perception of managers and technicians in order to understand the process of elaboration of the rules, the behind the scenes, and negotiations. Our findings highlight that social participation has been formally ensured in many aspects, revealing democratic advancements in the field of Protected Areas management in Brazil. However, despite remarkable progress, many challenges remain, including aspects of representation, independency, level of influence, and sharing power in decision-making processes. The outcomes of participation are ongoing processes of learning and negotiation, which are reflected in the improvement of the legal arrangements analyzed.

Resumen Los Consejos Gestores han sido considerados instrumentos institucionales de administración, que son innovadores al ejercicio de la democracia brasileña en el campo socio ambiental. Este artículo buscó integrar la evolución de los marcos regulatorios de los consejos gestores de áreas protegidas de Brasil y la visión de servidores involucrados en los procesos de formulación de las normas, a fin de comprender la trayectoria de negociación de esos procesos. Los resultados muestran que la participación social está formalmente garantizada en diversos aspectos de las normas analizadas, lo que debe considerarse una conquista para la gestión de áreas protegidas en Brasil. Sin embargo, se señalan algunas paradojas y desafíos, incluyendo cuestiones de representatividad, independencia, influencia y compartimentos genuinos de poder en la toma de decisiones. Los resultados sociales de la participación presuponen procesos continuos de aprendizaje y negociación, que se reflejan en el perfeccionamiento de los arreglos jurídicos analizados.

ABSTRACT Mycobacterium haemophilum is a nontuberculous mycobacterium that causes localized or disseminated disease, mainly in immunocompromised hosts. We report the case of a 35-year-old HIV-infected woman who presented with several enlarging cutaneous lesions over the arms and legs. Histopathological examination revealed the diagnosis of a cutaneous mycobacterial disease. Mycobacterial analyses unveiled M. haemophilum infection. Six months after completion of a successful antimycobacterial treatment, she developed an immune reconstitution inflammatory syndrome (IRIS). This paradoxical relapse presented as tenderness, redness and swelling at the precise sites of the healed lesions and took place in the setting of significant recovery of the CD4 cell count (from 05 to 318 cells/mm 3 ). Microbiological analyses of these worsening lesions were negative, and they spontaneously remitted without the initiation of a novel antimycobacterial treatment cycle. M. haemophilum infection should always be considered as a cause of skin lesions in immunocompromised subjects. Physicians should be aware of the possibility of IRIS as a complication of successful antiretroviral therapy in HIV-infected patients with M. haemophilum infection.

Abstract The compatibilization of recycled PP/PET blend with high and low concentration (20 and 5 phr) of elastomer functionalized by maleic anhydride (SEBS-g-MA) was achieved. Recycled polypropylene from plastic industry and recycled PET from post-consumer bottles was used. PP/PET blends: 80:20 w/w, 50:50 w/w and 20:80 w/w were prepared in an internal mixer for mechanical properties, thermal properties, morphology and rheological properties. SEBS-g-MA promoted compatibilization of the PP/PET blends and improved their properties. With an increasing compatibilization level, the refinement of morphology was observed in the PET rich blend. Compatibilized blends showed negative deviation in the PET glass transition temperature related to neat PET, demonstrating that compatibilization was very successful. PET crystallization was accelerated in the blends due to PP presence that enhanced nucleation. It was found that the 50/50/20 blend showed huge potential for textile fiber application and that of 80/20/20 showed more intermediary properties than neat polymers.

ABSTRACT Bacillary angiomatosis (BA) is an angioproliferative disease of immunocompromised patients that usually presents as vascular tumors in the skin and subcutaneous tissues. It is caused by chronic infections with either Bartonella henselae or B. quintana. Oral cavity BA is exceedingly rare and even rarer without simultaneous cutaneous disease. We report herein the case of a 51-year-old HIV-infected man who presented severe odynophagia and an eroded lesion on the hard palate that progressed to an oronasal fistula. No cutaneous lesions were recorded. Doxycycline led to complete resolution. To the best of our knowledge, only six previous cases of oral BA without tegumentary disease have been previously reported and none of them progressed to fistula.

RESUMO: A espécie florestal Dimorphandra gardneriana Tul. é bastante utilizada para diversos produtos farmacológicos, mesmo assim há poucos estudos básicos para compreender seus atributos ecológicos e fisiológicos sob condições de estresse. Desta forma, o objetivo nesta pesquisa foi avaliar a germinação e o vigor de suas sementes quando submetidas a diferentes potenciais osmóticos e temperaturas. A restrição hídrica foi simulada com solução de polietilenoglicol 6000 (PEG 6000) nos potenciais osmóticos de 0; -0,2; -0,4; -0,6; -0,8 e -1,0MPa nas temperaturas constantes de 20, 25, 30 e 35°C. Na avaliação do efeito dos tratamentos, determinou-se a germinação e o vigor (índice de velocidade de germinação, comprimento e fitomassa seca de parte aérea e raízes) das sementes, em delineamento inteiramente ao acaso, em quatro repetições. A partir de -0,4MPa ocorre redução drástica da germinação e vigor das sementes, fatores estes menos afetados na temperatura de 25°C até-0,2MPa.

ABSTRACT: The forest species Dimorphandra gardneriana Tul. is widely used for various pharmacological products, yet few basic studies have been undertaken to understand their ecological and physiological attributes under stress conditions. The goal of this research was to evaluate the seed germination and vigor when subjected to different osmotic potentials and temperatures. Water restriction was simulated with polyethylene glycol 6000 solution (PEG 6000) with osmotic potentials of 0; -0,2; -0,4; -0,6; -0,8, and -1,0MPa at temperatures of 20, 25, 30, and 35°C. The effect of the treatment was determined by the germination and vigor (germination speed index, length and phytomass of dry shoot and roots) of the seeds, in an entirely random design with four repetitions. From-0, 4MPa it occurs a drastic reduction in germination and vigor of seeds although these factors were less affected at temperature of 25°C up to -0, 2MPa.

RESUMO: Este estudo teve por objetivo avaliar os efeitos da administração por via oral de Alopurinol em potros nascidos de éguas com placentite. Vinte potros foram divididos em dois grupos: potros saudáveis (n=10), nascidos de éguas sem placentite, e potros placentite (n=10), nascidos de éguas com placentite. Cinco potros de cada grupo foram selecionados aleatoriamente para compor o grupo tratado ou controle. Os grupos tratados receberam Alopurinol (40mg kg-1 PO na sexta hora de vida). Foram coletadas amostras sanguíneas para realização de análise hematológica e avaliação das concentrações séricas de cálcio, cloretos, creatinina, fósforo, glicose, lactato e magnésio. Os potros placentite apresentaram leucopenia e neutropenia, comparado com os potros saudáveis no momento do nascimento. O grupo placentite não tratado apresentou leucopenia no momento 12 horas. Não foram observados efeitos adversos relacionados ao uso do Alopurinol. O grupo placentite tratado apresentou maiores concentrações de cálcio e glicose em relação ao grupo placentite não tratado, nas 12 horas. A administração de Alopurinol por via oral em dose única em potros nascidos de éguas com placentite não resultou em efeitos adversos e pode ter contribuído para a estabilização dos níveis de cálcio e glicose.

ABSTRACT: The aim of this study was to evaluate the effects of Allopurinol in foals born from mares with placentitis. Twenty foals were assigned into two groups: Healthy foals (n=10), born from healthy mares and Placentitis foals (n=10), born from mares with placentitis. Five foals from each group were randomly assigned to a treatment or control group. Treatment groups received Allopurinol (40mg kg-1 orally six hours after birth). Blood samples were collected for estimation of hematological variables and serum concentration of calcium, chloride, creatinine, phosphorus, glucose, lactate and magnesium. Placentitis foals presented leukopenia and neutropenia when compared with Healthy foals, at birth. The white blood cell (WBC) count was lower in the Placentitis foals untreated at 12 hours. No adverse effects related to the use of Allopurinol were detected. Treated Placentitis foals showed higher serum calcium and glucose levels within 12 hours than untreated Placentitis foals. Administration of Allopurinol PO in foals born from mares with placentitis did not result in adverse effects and can help in stabilizing serum calcium and glucose levels.

Esta pesquisa foi conduzida com o objetivo de avaliar o efeito in vitro e in vivo do óleo de eucalipto (Corymbia citriodora) sobre o carrapato bovino (Rhipicephalus (Boophilus) microplus). Na experimentação in vitro, foi utilizado o grupo controle negativo e oito concentrações de óleo de eucalipto (0,5; 1; 2; 5; 10; 20; 50; 100%), em fêmeas ingurgitadas de carrapato. A eficácia de controle foi de 0; 30,5; 75,5; 91; 100; 100; 100; 100 e 100%, respectivamente. Para a experimentação in vivo, foram constituídos três grupos (controle negativo; óleo de eucalipto a 3,5% - nível estimado mediante análise de regressão, correspondendo a 95% de eficácia de controle do carrapato da pesquisa in vitro e amitraz a 0,025%), com dezoito vacas da raça Holandesa. Antes (média dos dias -3, -2,-1) e após a aplicação do produto (1, 2, 3, 5, 7, 10, 14, 21dias), foram contadas fêmeas ingurgitadas de carrapato. A eficácia de controle foi de 0; 96,4 e 69%, respectivamente, 21 dias após o tratamento. Na 1ª e na 2ª ordenha após a aplicação dos tratamentos, foram avaliadas variáveis fisiológicas e coletadas amostras de leite para avaliar as propriedades organolépticas no leite e no iogurte (controle negativo x tratamento fitoterápico). O teste de aceitação sensorial do leite e das variáveis fisiológicas avaliadas foram similares entre os tratamentos.

This research was aimed at evaluating in vitro and in vivo effects of eucalyptus (Corymbia citriodora) oil on cattle ticks (Rhipicephalus (Boophilus) microplus). Negative control group and eight concentrations of eucalyptus oil (0.5; 1; 2; 5; 10; 20; 50; 100%), were used on in vitro trials with engorged female ticks. The efficacy of control ticks was 0; 30.5; 75.5; 91; 100; 100; 100; 100 and 100%, respectively. At the in vivo trial eighteen Holstein cows were allocated to three groups (negative control, eucalyptus oil at 3.5% - level estimated by regression analysis, accounting for 95% efficacy of control ticks on in vitro trial and amitraz at 0.025%). Engorged female ticks were counted before (mean of days -3, -2, -1) and after treatment (1, 2, 3, 5, 7, 10, 14, 21 days). The efficacy control tick was 0; 96.4 and 69%, respectively, at 21 days after treatment. On the 1st and 2nd milked after treatments, physiologic variables were evaluate and milk samples were collected to evaluate organoleptic properties in milk and yoghurt (negative control x phytotherapic treatment). Similar results were found with sensorial acceptance test of milk and physiologic variables.

Com as contínuas pesquisas sobre virada na natação são verificadas necessidades de padronizar métodos e protocolos utilizados para a avaliação. Este estudo objetivou propor uma padronização para a distância de análise do desempenho da virada na natação. Participaram 11 nadadores (16±3 anos) velocistas de ambos os sexos. Com uma plataforma de força foram obtidas as variáveis: Pico de Força (PF) e Tempo de Contato (TC). Com cinco filmadoras obteve-se tempo de virada em 15 m (TV15m), tempo de virada em 10 m (TV10m), distância antes da virada (DAV), distância de retomada de nado (DRN) e tempo sem nado (TSN). Foi utilizada estatística com p<0,01. O valor médio para o PF foi de 1075 N e para o TC de 0,32 s. As variáveis TV10m e TV15m registraram média de 5,52 e 8,81 s, respectivamente. As variáveis PF e TC tiveram relação com o desempenho da virada nas distâncias de 10 e 15 m. Entretanto esta relação apresenta-se mais forte ao analisar o tempo sem nado, que contempla as fases da virada. Confirmou-se que as variáveis PF e TC têm relação com o desempenho da virada para as distâncias de 10 e 15 m. Foi observado que a 10 m é suficiente avaliar atletas com características técnicas semelhantes aos deste estudo. Outros nadadores com diferentes características técnicas, tal como um maior aproveitamento da fase submersa sugere-se ao pesquisador utilizar a medida de 15 metros (5 m antes e 10 m após a virada).

The ongoing research on freestyle flip turns requires the standardization of assessment methods and protocols. The objective of this study was to propose a standardization of the distance used for the analysis of flip-turn performance. Eleven swimmers of both genders (16±3 years) participated in the study. Peak force (PF) and contact time (CT) were measured using a force platform. Five camcorders were installed to determine the flip-turn time at a distance of 15 (TT15) and 10 m (TT10), distance before the turn, distance to regain stroke, and time without stroke. Each swimmer performed eight flip turns. The level of significance was set at p<0.01. Mean PF was 1075 N and mean CT was 0.32 s. Mean TT10 and TT15 were 5.52 and 8.81 s, respectively. PF and CT were associated with flip-turn performance at distances of 10 and 15 m. However, this association was stronger when analyzing time without stroke, which is part of the flip-turn phases. In conclusion, PF and CT were associated with flip-turn performance at distances of 10 and 15 m. A distance of 10 m was found to be sufficient to evaluate athletes with technical characteristics similar to those of this study. The use of the 15-m distance is recommended for swimmers with different technical characteristics, such as a longer underwater phase.
