ABSTRACT The aim of this study was to analyse patterns of spatial dispersal in Ceratitis capitata using two types of attractive traps and propose a predictive model of pest dispersal with the aim of determining management zones for decision-making. The experiment was conducted in an orchard of the ‘Palmer’ mango in the district of Belo Campo, Bahia. Sampling was carried out using McPhail and Jackson traps. The pattern of spatial dispersal in C. capitata was determined using the Perry and Mead Index of Dispersion, the Morisita Index, and the Local Moran index (LISA). The spatial variability of the abundance of C. capitata was obtained by geostatistical analysis, with the indicator kriging method used to prepare the location and spatial distribution maps. The Perry and Mead Index of Dispersion and the Morisita Index showed an aggregated pattern of spatial dispersal, whereas the Moran Local index showed a random pattern from 7 DFSH (days from the start of the harvest) to 35 DFSH, and an aggregated pattern at 42 DFSH. The SDI was strong at 7 and 35 DFSH and moderate at 14, 28 and 42 DFSH. The dispersal patterns of C. capitata allow an exponential predictive model to be produced, outlining strategies for exponential management zones of C. capitata, and detecting which places have the highest risk of the pest occurring.

Abstract In the Amazonian Forest, diverse plants have bioactive compounds, which can potentially be used as modulators of ruminal fermentation. Despite the importance, few studies have been developed to evaluate the use of extracts from Amazonian plants as natural feed additives in ruminant nutrition. Thus, the objective of this study is to present a brief overview of the scientific data in the literature regarding the effects of the use of extracts of açaí, copaíba, sage-do-marajó, peach palm, and bacuri on the ruminal fermentation and their potential for use in the diet of ruminants. Açaí (Euterpe oleracea Mart.) has 16.08 mg/g of dry matter of flavonoids, compounds with potent antimicrobial activity. Studies with açaí oil supplementation have shown modulatory effects on rumen fermentation and milk production in sheep and cows. Additionally, the copaiba oleoresin (Copaifera spp.) and the bacuri (Platonia insignis Mart.) seed butter have 88% and 41% of terpenes, respectively; the phytochemical composition of marajó sage oil (Hyptis crenata Pohl ex Benth) is not completely resolved, but this source is mostly composed of the terpenes, camphor (33.62%), 1,8-cineole (19.76%) and α-pinene (15.24%), which have in vitro antimicrobial effects against different bacterial strains. The findings of this review demonstrate the potential of Amazonian extracts in maximizing animal production, due to the possible effects on the modulation of ruminal fermentation, being encouraged to carry out additional studies aiming at a greater exploration of them. Although, there are no current studies associated with the effects of açaí, sage, peach palm, and bacuri on rumen fermentation, it is inferred that, due to their phytochemical composition, they may have a similar effect to ionophores on ruminant production.

Resumen En la selva amazónica, innumerables plantas poseen compuestos bioactivos, que potencialmente pueden ser utilizados como moduladores de la fermentación ruminal. A pesar de la importancia, han sido desarrollados pocos estudios evaluando el uso de extractos de plantas amazónicas como aditivos alimentarios naturales en la nutrición de rumiantes. Así, el objetivo de este estudio es presentar un breve panorama de los datos científicos en la literatura sobre los efectos del uso de extractos de açaí, copaíba, salvia-do-marajó, chontaduro y bacuri en la fermentación ruminal y su potencial de uso en la dieta de los rumiantes. Açaí (Euterpe oleracea Mart.) tiene 16,08 mg/g de materia seca de flavonoides, compuestos con potente acción antimicrobiana. Los estudios con suplementos de aceite de açaí han demostrado efectos moduladores sobre la fermentación ruminal y la producción de leche en ovejas y vacas. Adicionalmente, la oleorresina de copaiba (Copaifera spp.) y la mantequilla de semilla de bacuri (Platonia insignis Mart.) poseen 88% y 41% de terpenos, respectivamente; la composición fitoquímica del aceite de salvia de marajó (Hyptis crenata Pohl ex Benth) no está completamente resuelta, sin embargo esta fuente está mayoritariamente compuesta de los terpenos alcanfor (33,62%), 1,8-cineol (19,76%) y α-pineno (15,24%), los cuales poseen efecto antimicrobiano in vitro frente a diferentes cepas bacterianas. Los hallazgos de esta revisión demuestran el potencial de los extractos amazónicos en la maximización de la producción animal, debido a sus posibles efectos sobre la modulación de la fermentación ruminal, siendo incentivados a realizar estudios adicionales con el objetivo de una mayor exploración de estos. Aunque actualmente no existen estudios asociados a los efectos del açaí, la salvia, el chontaduro y el bacuri en la fermentación ruminal, se supone que, por su composición fitoquímica, podrían tener un efecto similar a los ionóforos en la producción de rumiantes.

Resumo Na flora amazônica, incontáveis plantas possuem compostos bioativos, que potencialmente podem ser utilizados como moduladores da fermentação ruminal. Apesar da importância, poucos estudos têm sido desenvolvidos para avaliar a utilização de plantas amazônicas como aditivos alimentares naturais na nutrição de ruminantes. Assim, objetiva-se apresentar um panorama dos dados científicos da literatura sobre os efeitos do uso dos extratos de açaí, copaíba, salva-do-marajó, pupunha e bacuri na fermentação ruminal e os seus potenciais de utilização na dieta de ruminantes. O açaí (Euterpe oleracea Mart.), possui 16,08 mg/g de matéria seca de flavonoides, compostos com potente ação antimicrobiana. Estudos com suplementação do óleo de açaí tem mostrado efeitos modulatórios na fermentação ruminal e na produção de leite de ovelhas e vacas. Adicionalmente, a oleoresina de copaíba (Copaifera spp.) e a manteiga das sementes de bacuri (Platonia insignis Mart.), possuem, respectivamente, 88% e 41% de terpenos; a composição fitoquímica do óleo de salva-do-marajó (Hyptis crenata Pohl ex Benth) ainda não está completamente caracterizada, mas esta fonte está majoritariamente composta por terpenos cânfora (33,62%), 1,8-cineol (19,76%) e α-pineno (15,24%), que apresentam atividade in vitro antimicrobiana, capaz de reduzir a produção total de gás em ambiente ruminal in vitro. A pupunha, fruto da pupunheira (Bactris gasipaes Kunth.), possui 355,95 mg/kg de carotenoides, com efeito antimicrobiano in vitro contra algumas cepas bacterianas. Os achados desta revisão demonstram as potencialidades dos extratos amazônicos na maximização da produção animal, em razão dos possíveis efeitos na modulação da fermentação ruminal, sendo encorajada a realização de estudos adicionais visando uma maior exploração deles. Embora, atualmente, não existam estudos associados aos efeitos do açaí, salva-do-marajó, pupunha e bacuri na fermentação ruminal, pressupõe-se que pela sua composição fitoquímica, poderiam ter um efeito semelhante aos ionóforos na produção de ruminantes.

Resumo O artigo aborda a retirada compulsória de filhos de mulheres em situação de vulnerabilidade no Brasil. Objetivou-se refletir sobre a violação do direito à maternidade; apresentar os limites impostos, especialmente às mulheres pobres, negras e indígenas e as estratégias de controle sobre sua vida e de seus filhos; e os movimentos de resistência que se contrapõem às segregações. Foram fontes da pesquisa: narrativas de mulheres em situação de vulnerabilidade, de familiares e trabalhadores da saúde; entrevistas com atores estratégicos; análise documental; diários de campo. Evidenciou-se que vulnerabilidades atreladas à criminalização da pobreza e ao preconceito racial têm justificado as separações. A desresponsabilização do Estado e da sociedade quanto à formação de uma rede de apoio às mulheres, a desvalorização de produções não hegemônicas de maternidades e o reforço de uma razão de mundo que produz a violência como ferramenta para exclusão vão conformando limites práticos quanto ao direito à maternidade. Mulheres e seus filhos são desconsiderados em suas singularidades. Os movimentos de resistência mostraram que diálogos intersetoriais são uma alternativa para superar discriminações e vulnerabilidades.

Abstract This article addresses the compulsory seizing of children from vulnerable women in Brazil. Its objectives were: to discuss the violation of the right to maternity; to present the imposed restrictions especially on poor, black and indigenous women; the strategic control over their lives and children, and the resistance movements that oppose segregation. The sources of the research were: narratives of women in vulnerable situations, family members and health workers; interviews with strategic actors; document analysis; field journal. It became evident that vulnerabilities -linked to the criminalization of poverty and racial prejudice- have justified these separations. The lack of responsibility that State and society practice towards the support network for women, the devaluation of non-hegemonic productions of maternity, and the reinforcement of a ‘reason of the world’, that produces violence as a tool for exclusion establishing practical limits on the right to maternity. Women and children are disregarded in their singularities. Resistance movements have shown that intersectoral dialogues are an alternative to overcome discrimination and vulnerabilities.

Abstract The aim of this scoping review was to provide sufficient information about the effectiveness of ozone gas in virus inactivation of surfaces and objects under different environmental conditions. The review was performed according to the list of PRISMA SrC recommendations and the JBI Manual for Evidence Synthesis for Scoping Reviews. The review was registered in Open Science Framework (OSF). EMBASE (Ovid), Lilacs, LIVIVO, MEDLINE (PubMed), SciELO, Scopus and Web of Science were primary sources, and “gray literature” was searched in OpenGray and OpenThesis. A study was included if it reported primary data on the effect of ozone gas application for vehicle-borne and airborne virus inactivation. No language or publication date restriction was applied. The search was conduct on July 1, 2020. A total of 16,120 studies were screened, and after exclusion of noneligible studies, fifteen studies fulfilled all selection criteria. Application of ozone gas varied in terms of concentration, ozone exposure period and the devices used to generate ozone gas. Twelve studies showed positive results for inactivation of different virus types, including bacteriophages, SARS-CoV-2 surrogates and other vehicle-borne viruses. Most of the studies were classified as unclear regarding sponsorship status. Although most of the population has not yet been vaccinated against COVID-19, disinfection of environments, surfaces, and objects is an essential prevention strategy to control the spread of this disease. The results of this Scoping Review demonstrate that ozone gas is promising for viral disinfection of surfaces.

ABSTRACT Hand-foot-and-mouth disease (HFMD) is a highly contagious viral disease commonly associated to Enteroviruses (EV). During 2018, Brazil faced massive HFMD outbreaks spread across the country. This study aimed to characterize the EV responsible for the HFMD outbreak that occurred in Paraiba State, Brazilian Northeastern region, in 2018, followed by a phylogenetic analysis to detail information on its genetic diversity. A total of 49 serum samples (one from each patient) collected from children ≤ 15 years old, clinically diagnosed with HFMD were tested for EV using conventional RT-PCR and RT-qPCR. EV infection was confirmed in 71.4% (35/49) of samples. The mean and median ages were 1.83 years and one year old, respectively. Twenty-two EV-positive samples were successfully sequenced and classified as EV-A species; 13 samples were also identified with the CV-A6 genotype. The phylogenetic analysis (VP1 region) of three samples revealed that the detected CV-A6 strains belonged to sub-lineage D3. The CV-A6 strains detected here clustered with strains from South America, Europe and West Asia strains that were also involved in HFMD cases during the 2017-2018 seasons, in addition to the previously detected Brazilian CV-A6 strains from 2012 to 2017, suggesting a global co-circulation of a set of different CV-A6 strains introduced in the country at different times. The growing circulation of the emerging CV-A6 associated with HFMD, together with the detection of more severe cases worldwide, suggests the need for a more intense surveillance system of HFMD in Brazil. In addition, this investigation was performed exclusively on serum samples, and the analysis of whole blood samples should be considered and could have shown advantages when employed in the diagnosis of enteroviral HFMD outbreaks.

Abstract: Solubility, pH, ion release, cytotoxicity, and osteoclastogenesis inhibition in bone marrow-derived monocyte macrophages (BMMs) were evaluated in EndoSequence BC Sealer (END), Bio-C Sealer (BC), and Sealer Plus BC (SPBC). pH was determined after immersion of the sealers in deionized water (DW) and Minimum Essential Medium Alpha (α-MEM). Solubility was obtained by mass loss. Ion release was measured by using X-ray fluorescence spectroscopy (XRF). Cytotoxicity was evaluated by MTT assay. Inhibition of osteoclastogenesis was evaluated by tartrate-resistant acid phosphatase (TRAP). Data were analyzed using the t-test, ANOVA and Tukey/Dunnett's post-hoc tests (α = 0.05). END had the highest pH in DW (p < 0.05), and BC, in α-MEM (p < 0.05). Solubility in DW was the lowest for SPBC (p < 0.005). The highest calcium release was observed for BC in DW at 12 h (p < 0.05), and in α-MEM at 12 and 24 h (p < 0.05). The lowest toxicity was detected for END (p < 0.05). BC had the highest inhibitory effect on osteoclasts (p < 0.05). Overall, the highest solubility and pH values were found in DW. However, the calcium silicate-based sealer showed higher solubility than the ISO standards. Calcium release was the highest for BC. END showed the highest cell viability, and BC, the highest osteoclast inhibition.

Abstract Cheese whey is the main by-product obtained in the production of cheese. Despite its high nutritional value, approximately half of the whey volume generated is still disposed incorrectly, which causes damage to the ecosystem due to the high cheese whey pollutant load. Therefore, it is important to use this by-product and its components in an increasing number of applications, especially as food ingredient. This review aimed to show the technology of production of butter from whey cream, as well as showing the physico-chemical, sensory, and nutritional characteristics of the product. There were no significant variations in the physico-chemical composition of milk cream butter and whey cream butter in the literature available. As the technology to produce whey butter is quite simple, this by-product has potential to be exploited by the dairy industry. Additionally, further studies on production process, characterization, and sensory analysis are required to enable its large-scale production.

Resumo O soro de queijo é o principal coproduto obtido durante o processo de fabricação de queijos. Apesar de possuir um valor nutricional elevado, cerca da metade do volume de soro gerado ainda é descartada de forma incorreta, constituindo-se uma prática prejudicial para o ecossistema devido à enorme carga poluente do soro de queijo. Dessa forma, é importante a utilização desse coproduto e de seus componentes em um número maior de aplicações, especialmente como ingrediente alimentício. O objetivo deste artigo de revisão é apresentar a tecnologia para produção da manteiga a partir do reúso do creme de soro de queijo, demonstrando as características físico-químicas, sensoriais e nutricionais do produto, e apontando as alternativas e possíveis utilizações para os principais componentes do soro. Na comparação entre a manteiga de creme de leite e a manteiga de creme de soro, na literatura disponível, os resultados não apresentam variações significativas em relação à sua composição físico-química. Dada a simplicidade da tecnologia de produção, a manteiga de soro possui potencial para ser explorada pelas indústrias lácteas. Além disso, mais estudos sobre o processo de fabricação, caracterização e análise sensorial são necessários para viabilizar sua produção em maior escala.

RESUMO Objetivo: Analisar os efeitos da estimulação elétrica neuromuscular do quadríceps femoral associado ou não à suplementação com whey protein na atividade eletromiográfica e distribuição de massa corporal em voluntários submetidos à reconstrução do ligamento cruzado anterior. Métodos: 24 voluntários foram divididos em três grupos: controle basal, whey protein associado com estimulação elétrica neuromuscular e estimulação elétrica neuromuscular isolada. Resultados: Na avaliação pós-operatória, durante o miniagachamento, o grupo controle basal demonstrou diminuição da atividade eletromiográfica do vasto medial (p = 0,005, olhos abertos; p = 0,003, olhos fechados), vasto lateral (p = 0,005, olhos abertos; p = 0,020, olhos fechados) e reto femoral (p = 0,075, olhos abertos; p = 0,074, olhos fechados) e da distribuição de massa corporal no membro operado (p < 0,001, olhos abertos; p < 0,001, olhos fechados) e membro lesionado (p < 0,001, olhos abertos; p < 0,001, olhos fechados). Conclusão: O uso precoce de estimulação elétrica neuromuscular do quadríceps femoral, independentemente do uso de whey protein, foi eficaz para manter a atividade eletromiográfica dos músculos vasto medial e vasto lateral, e prevenir assimetrias na distribuição de massa corporal 15 dias após a reconstrução do ligamento cruzado anterior. Nível de Evidência I, Ensaio randomizado de alta qualidade.

ABSTRACT Objective: To analyze the effects of neuromuscular electrical stimulation of the femoral quadriceps associated or not with whey protein supplementation on the electromyographic activity and body mass distribution in volunteers undergoing anterior cruciate ligament reconstruction. Methods: 24 volunteers were randomly divided into three groups: basal control, whey protein in association with neuromuscular electrical stimulation, and neuromuscular electrical stimulation alone. Results: In the postoperative evaluation, during the mini squat, the basal group showed a decrease in the electromyographic activity of the vastus medialis (p = 0.005, eyes open; p = 0.003, eyes closed), vastus lateralis (p = 0.005, eyes open; p = 0.020; eyes closed) and rectus femoris (p = 0.075, eyes open; p = 0.074, eyes closed) and of body mass distribution in the injured limb (p < 0.001, eyes open; p < 0.001, eyes closed), and in the healthy limb (p < 0.001, eyes open; p < 0.001, eyes closed). Conclusion: The early use of neuromuscular electrical stimulation of the quadriceps femoris maintained the electromyographic activity of the vastus medialis and vastus lateralis muscles and prevented asymmetries in body mass distribution 15 days after anterior cruciate ligament reconstruction. Level of Evidence I, High quality randomized trial.

Resumo O objetivo deste artigo é investigar a relação da violência física entre parceiros íntimos (VFPI) e a oferta de leite materno (LM), os substitutos do leite materno (SLM) e o uso de mamadeiras entre crianças entre 12 e 15 meses. Estudo transversal com mães em unidades de saúde do município do Rio de Janeiro, realizado entre junho de 2005 e dezembro de 2009. A VFPI foi identificada pela versão brasileira da Conflict Tactics Scales 1- Form R e as práticas de alimentação foram identificadas por recordatório de 24 horas. As associações foram verificadas por regressão logística mediante estimativas de razão de chances (RC) e intervalos de confiança de 95%. O leite materno foi ofertado a 58,5% das crianças e os substitutos do leite materno a 88,5%, e 70,5% das crianças usavam mamadeira. A violência física foi observada em 26,7% dos casais. Em lares onde os casais se agridem fisicamente há uma maior chance de não ofertar leite materno, maior chance de ofertar substitutos do leite materno e de usar mamadeira comparado aos lares onde não existe violência física. Os resultados chamam atenção para a necessidade de se investigar as relações intrafamiliares em casos que são identificadas práticas inadequadas de aleitamento, e de capacitar os profissionais de saúde para apoiar as famílias em situações de conflito.

Abstract This article aims to investigate the relationship between intimate partner physical violence (IPPV) and breastfeeding (BF), use of breastmilk substitutes (BMS) and bottle-feeding among children aged 12 to 15 months. This is a cross-sectional study with mothers in primary care facilities of the city of Rio de Janeiro. IPPV was identified by the Brazilian version of the Conflict Tactics Scales 1-Form R and feeding practices were identified by a 24-hour Dietary Recall. Associations were verified by logistic regression with odds ratio (OR) estimates and 95% confidence intervals. BF was offered to 58.5% of the children and BMS to 88.5%. Also, 70.5% of the children used a baby bottle. Physical violence was observed in 26.7% of couples. Households where couples physically abuse each other are more likely to not breastfeed (OR=2.14, p-value=0.030), to use breastmilk substitutes (OR=5.15, p-value=0.03) and bottle-feed (OR=2.71; p-value=0.01), when compared to households without physical violence. The results highlight the need to investigate intrafamily relationships in cases where inadequate breastfeeding practices are identified, and to enable health professionals to support families in conflict situations.

ABSTRACT Objectives: To evaluate the performance of telemonitoring in detecting clinical and psychological needs and adherence to the protective measures imposed by the COVID-19 pandemic in addition to providing remote assistance for patients with type 1 diabetes (T1D) in a public university center in Brazil. Subjects and methods: Telemonitoring protocol included phone calls and e-mails. Patients were asked to rate COVID-19-like symptoms, psychological symptoms, epidemiological issues, and adherence to diabetes management (insulin, exercise, and diet) using a 0-to-10 scale. An e-mail address and phone number were offered for further contact if needed. Clinical, demographic, and laboratorial data from the consultations before the pandemic were collected from medical records. Results: Among 321 patients with a previously scheduled consultation over the first 15 weeks of social distancing, 237 (73.8%) could be successfully contacted. Of these, 207 (87.3%) were exclusively evaluated by telemonitoring (190 only by phone or text message and 17 who were also reached by email), and 30 (12.7%) patients attended the consultation for medical reasons detected during the telephone screening. Overall, 44 (18.5%) patients reported COVID-19-like symptoms. One (2.3%) patient was hospitalized and subsequently died. Psychological symptoms were reported by 137 (60.4%) patients and 30 (12.7%) required remote psychological assistance. Appropriate social distancing was performed by 203 (87.9%) patients, and 221 (97.8%) referred use of masks. Conclusions: Telemonitoring T1D patients during the pandemic helped reduce the need for in-person consultations, detect clinical and psychological needs, and offer support to patients in addition to monitoring suspected COVID-19 cases and the adherence to protective measures.

RESUMO A busca por proteases de origem vegetal aumenta gradualmente devido à sua diversidade e estabilidade em ampla faixa de pH e temperatura. As flores da alcachofra são uma fonte vegetal proteolítica já estudada, porém suas folhas são escassas nesse aspecto. Assim, o objetivo dessa pesquisa foi a obtenção de extratos das folhas da alcachofra com diferentes tampões e métodos de extração como fonte alternativa proteolítica e coagulante vegetal, bem como a separação e comparação do perfil proteico desses extratos. A metodologia utilizada foi baseada na extração com tampão de citrato de sódio (pH 3), acetato de sódio (pH 5) e tris-HCl (pH 7), por agitação mecânica (AM) e ultrassom (US); determinação de proteínas; atividade proteolítica (AP) e atividade específica (AE); atividade de coagulação do leite (ACL) e potencial de substituição do coalho (PSC); análise de cromatografia liquida de alta eficiência (HPLC) com detector UV-Vis e análise de componentes principais (ACP). Os extratos das folhas Cynara scolymus apresentaram resultados elevados no extrato com Citrato-US para os parâmetros AP (14,38), AE (19,71), ACL (440) e PSC (30,60) comparados aos demais tratamentos. Os extratos com citrato e acetato tiveram tempo de coagulação rápido (máx 3 min). A análise de HPLC possibilitou a separação dos diferentes compostos proteicos presentes nos extratos e picos mais expressivos nas amostras com Citrato-AM e Acetato-AM; e picos isolados para o Citrato-US. Conclui-se que os extratos das folhas da alcachofra com o tampão citrato e acetato atribuíram resultados satisfatórios para atuarem como coagulante vegetal, bem como para realização de novos estudos para purificação de enzimas proteolíticas e aplicação em queijos.

ABSTRACT The search for origin plant-based proteases increases gradually due to their diversity and stability over a wide range of pH and temperature. Artichoke (Cynara scolymus) flowers are a proteolytic vegetable source already studied, but their leaves are scarce in this respect. Thus, the objective of this research was to obtain extracts of artichoke leaves with different buffers and extraction methods as an alternative proteolytic source and plant coagulant, as well as the separation and comparison of the protein profile of these extracts. The methodology used was based on extraction with sodium citrate buffer (pH 3), sodium acetate (pH 5) and Tris-HCl (pH 7) by mechanical stirrer (MS) and ultrasound (US); protein determination; proteolytic activity (PA) and specific activity (SA); milk clotting activity (MCA) and rennet substitution potential (RSP); high- performance liquid chromatography analysis (HPLC) with UV-Vis detector and principal component analysis (PCA). Extracts of Cynara scolymus leaves showed high results with Citrate-US for the parameters PA (14.38), SA (19.71), MCA (440) and RSP (30.60) compared to other treatments. The extracts with citrate and acetate presented a quick coagulation time (max 3 min). The HPLC analysis enabled the separation of the different protein compounds present in the extracts and most expressive peaks in the samples with Citrate-MS and Acetate-MS; and isolated peaks for Citrate-US. It was concluded that extracts of artichoke leaves with citrate and acetate buffer attributed satisfactory results to act as plant coagulant, as well as to carry out further studies for the purification of proteolytic enzymes and application in cheeses.

Abstract This study evaluated the effect of a cyclopentenone-type PG, 15-Deoxy-Δ12,14-PG J2 (15d-PGJ2), and lectin (ScLL) on the viability of human gingival fibroblasts (HGFs), and on IL-6 and TGFβ-1 release by these fibroblasts, stimulated with lipopolysaccharide (LPS). HGFs were stimulated with LPS 10 μg/ml and treated with 15d-PGJ2 1 and 2 μg/ml, and ScLL 2 and 5 μg/ml, for 1 and 3h, and then evaluated for viability by MTT assay. Supernatant was collected to detect IL-6 and TGFβ-1 release, by ELISA. Positive control was cells kept in Dulbecco’s Modified Eagle’s Medium, and negative control was those kept in LPS. Data were analyzed by ANOVA and Dunnett’s test (α = 0.05). No significant difference was found in viability among experimental groups at 1h (p > 0.05). Percentage of ScLL 5 µg/ml viable cells was similar to that of positive control at evaluated periods (p > 0.05), whereas the other groups had lower levels than the positive control (p < 0.05). IL-6 release was statistically higher for ScLL 5 μg/ml and 15d-PGJ2 2 µg/ml at 1h, compared with the other treated groups and positive control (p < 0.05). No significant differences were found among the groups at 3h (p > 0.05), except for ScLL 2 µg/ml and 15d-PGJ2 1 µg/ml, which showed lower IL-6 release compared with that of negative control (p < 0.05). No significant difference was found among the groups for TGFβ-1 release (p > 0.05). Results indicated that ScLL 5 μg/ml did not interfere in viability, and ScLL 2 µg/ml and 15d-PGJ2 1 µg/ml demonstrated reduced IL-6 release. Tested substances had no effect on TGFβ-1 release.

RESUMO A caatinga corresponde a um dos dois maiores núcleos das Florestas Tropicais Sazonalmente Secas (FTSS) e se encontra totalmente inserida no território brasileiro. Objetivou-se com este estudo avaliar a estrutura de dois micro-habitats relacionando-a com as variáveis ambientais. Foram alocadas 24 parcelas, nas quais mensuramos o CAP e fizemos a identificação botânica de todos os indivíduos arbóreos com CAP ≥ 10 cm. Com a presença de lajedos de calcário na área, foi possível distinguir dois micro-habitats. A CCA e a análise de espécies indicadoras mostraram uma nítida distribuição das espécies de acordo com os micro-habitats. Concluímos que a presença dos lajedos de calcário proporcionou a formação dos micro-habitats, influenciando na distribuição e composição das espécies arbustiva-arbóreas, caracterizando a unidade fitoecológica aqui denominada como “furados”.

ABSTRACT Caatinga represents one of the two major centers of Seasonally Dry Tropical Forests (SDTF) and is completely inserted in the Brazilian territory. The present work aimed to evaluate the structure of two micro-environments and relate them to environmental variables. Twenty 20 × 20 m plots were placed in which we measured the height and CBH and made the botanical identification of all trees with CBH ≥10 cm. The CCA and indicator species analysis presented a clear distribution of species according to the micro-environments. We concluded that the presence of limestone slabs provided the formation of microhabitats, thus influencing the distribution and composition of tree species, what characterized the phytoecological unit here referred as “furados”.
