ABSTRACT

O alopurinol, de uso contínuo oral, é o tratamento de escolha para os distúrbios hereditários do glicogênio. Apesar de não ser comum, a reação de hipersensibilidade ao alopurinol se torna um problema quando esta é a única medicação disponível para o controle da doença de base. Nestes casos, a dessensibilização é uma alternativa viável. No presente relato, descrevemos o caso de um paciente com diagnóstico de doença de depósito de glicogênio tipo I, com exantema pruriginoso generalizado ao alopurinol, tratado com um protocolo de dessensibilização oral acelerado. Este tratamento permitiu o uso contínuo deste medicamento sem novas reações em longo prazo.


Continuous oral allopurinol use is the first-line treatment for hereditary glycogen disorders. While hypersensitivity reactions to allopurinol are uncommon, they can pose challenges when this medication is the only available option for the long-term treatment of the underlying disorder. In such cases, desensitization emerges as a viable alternative. We report the case of a patient with glycogen storage disease type I who developed a generalized pruritic rash due to allopurinol. Drug intolerance was successfully managed using a rapid oral desensitization protocol, which allowed an uneventful long-term use of allopurinol.

ABSTRACT

Grape skin is a wine by-product with a high fiber and phenolic compound content, with potential application as an ingredient in food products. This work aimed to study the hedonic and sensory perception of the consumer using the Check-all-that-apply about cereal bars made with grape skin flour (GSF) obtained from wine residue. Grape skin flour with different granulometric ranges (coarse and fine) was added to the cereal bars in different proportions (10, 15, and 20%) to replace the oat flakes present in the formulation. Sensory acceptance results showed that all bars had good acceptance scores (>6.42) and presented different sensory profiles. The cereal bar containing 15% of coarse GSF had good sensory acceptance with attributes "few dark spots," "light color," and "softer," with desirable sensory characteristics and from the nutritional point of view with high fiber content and bioactive compounds and it was considered the best formulation. Therefore, the incorporation of wine by-products in cereal bars showed excellent acceptability and the possibility of insertion in the market.

ABSTRACT

Introdução: A prevalência de cesarianas cresceu no Brasil. Gestação e parto são influenciados por aspectos culturais e econômicos da sociedade em que a gestante está inserida. Objetivo: Analisar fatores que influenciam a escolha da via de parto pela gestante. Métodos: Trata-se de revisão narrativa da literatura incluindo artigos publicados entre 2009 e 2020. Foram feitas buscas nas bases de dados Pubmed, LILACS e SciELO, com descritores "Bioética", "Cesárea", "Comportamento de escolha", "Decisão", "Direitos da mulher", "Gravidez", "Parto", "Parto normal", "Sistema único de saúde". Resultados: Foram encontradas taxas de cesariana no setor privado maiores do que no público. Menor idade materna e escolaridade, raça negra, residência em meio rural e nas regiões Norte e Nordeste foram associados a menor prevalência de cesariana. Obesidade materna, cesariana prévia, intercorrências na gravidez, apresentação fetal não cefálica, macrossomia estiveram mais relacionados a cesariana. Dor, previsibilidade, relação da mãe com o recém-nascido, alta hospitalar, vida sexual e retorno às atividades foram relacionados a escolha do parto vaginal. Discussão: A disparidade de cesarianas no setor público e privado sugere o impacto de aspectos financeiros na escolha. Variáveis socioeconômicas são importantes nessa decisão. Conclusões: A escolha da via de parto é influenciada por vários fatores. [au]


Introduction: The prevalence of caesarean sections has grown in Brazil. Pregnancy and childbirth are influenced by cultural and economic aspects of the society in which the pregnant woman is inserted. Objective: To analyze factors that influence the choice of the mode of delivery by the pregnant woman. Methods:This is a narrative literature review including articles published between 2009 and 2020. Searches were made in Pubmed, LILACS and SciELO databases, with descriptors "Bioethics", "Caesarean section", "Choice behavior", "Decision", "Women's rights", "Pregnancy", "Childbirth", "Normal delivery" and "The Unified Brazilian Health Care System". Results: Caesarean section rates were found to be higher in the private sector than in the public sector. Lower maternal age and education, black race, residence in rural areas and in the North and Northeast regions were associated with lower prevalence of caesarean section. Maternal obesity, previous caesarean section, complications in pregnancy, non-cephalic fetal presentation and macrosomia were more related to caesarean section. Pain, predictability, mother's relationship with the newborn, hospital discharge, sexual life and return to activities were related to the choice of vaginal delivery. Discussion: The disparity of caesarean sections in the public and private sectors suggests the impact of financial aspects on the choice. Socioeconomic variables are important in this decision. Conclusions: The choice of mode of delivery is influenced by several factors. [au]

ABSTRACT

The COVID-19 pandemic has created an unprecedented need for epidemiological monitoring using diverse strategies. We conducted a project combining prevalence, seroprevalence, and genomic surveillance approaches to describe the initial pandemic stages in Betim City, Brazil. We collected 3239 subjects in a population-based age-, sex- and neighborhood-stratified, household, prospective; cross-sectional study divided into three surveys 21 days apart sampling the same geographical area. In the first survey, overall prevalence (participants positive in serological or molecular tests) reached 0.46% (90% CI 0.12-0.80%), followed by 2.69% (90% CI 1.88-3.49%) in the second survey and 6.67% (90% CI 5.42-7.92%) in the third. The underreporting reached 11, 19.6, and 20.4 times in each survey. We observed increased odds to test positive in females compared to males (OR 1.88 95% CI 1.25-2.82), while the single best predictor for positivity was ageusia/anosmia (OR 8.12, 95% CI 4.72-13.98). Thirty-five SARS-CoV-2 genomes were sequenced, of which 18 were classified as lineage B.1.1.28, while 17 were B.1.1.33. Multiple independent viral introductions were observed. Integration of multiple epidemiological strategies was able to adequately describe COVID-19 dispersion in the city. Presented results have helped local government authorities to guide pandemic management.

ABSTRACT

ETHNOPHARMACOLOGICAL RELEVANCE: In Brazil, ethnopharmacological studies show that Libidibia ferrea (Mart. ex Tul.) L. P. Queiroz is commonly used in folk medicine as an antifungal, antimicrobial and anti-inflammatory. In the Amazon region, the dried fruit powder of L. ferrea are widely used empirically by the population in an alcoholic tincture as an antimicrobial mouthwash in oral infections and the infusion is also recommended for healing oral wounds. However, there are few articles that have evaluated the antimicrobial activity against oral pathogens in a biofilm model, identifying active compounds and mechanisms of action. AIM OF THE STUDY: The aim of this study was to evaluate the antimicrobial and anti-adherence activities of the ethanolic extract, fractions and isolated compounds (gallic acid and ethyl gallate) of the fruit and seed of L. ferrea against Streptococcus mutans. The inhibition of acidicity/acidogenicity and the expression of the S. mutans GTF genes in biofilms were also evaluated. MATERIALS AND METHODS: Minimal Inhibitory Concentration (MIC), Minimum Bactericidal Concentration (MBC) and Minimum Inhibitory Concentration of Cell Adhesion (MICA) were evaluated with ethanolic extract (EELF), fractions, gallic acid (GA) and ethyl gallate (EG) against S. mutans. Inhibition of biofilm formation, pH drop and proton permeability tests were conducted with EELF, GA and EG, and also evaluated the expression of the GTF genes in biofilms. The compounds of dichloromethane fraction were identified by GC-MS. RESULTS: This is the first report of shikimic, pyroglutamic, malic and protocatechuic acids identified in L. ferrea. EELF, GA and EG showed MIC at 250 µg/mL, and MBC at 1000 µg/mL by EELF. EELF biofilms showed reduced dry weight and acidogenicity of S. mutans in biofilms. GA and EG reduced viable cells, glucans soluble in alkali, acidogenicity, aciduricity and downregulated expression of gtfB, gtfC and gtfD genes in biofilms. SEM images of GA and EG biofilms showed a reduction of biomass, exopolysaccharide and microcolonies of S. mutans. CONCLUSIONS: The ethanolic extract of fruit and seed of L. ferrea, gallic acid and ethyl gallate showed great antimicrobial activity and inhibition of adhesion, reduction of acidogenicity and aciduricity in S. mutans biofilms. The results obtained in vitro validate the use of this plant in ethnopharmacology, and open opportunities for the development of new oral anticariogenic agents, originated by plants that can inhibit pathogenic biofilm that leads to the development of caries.

ABSTRACT

Trichilia ramalhoi Rizz. is a species from Meliaceae family and its chemical composition and biological activities are still unknown. This work describes the chemical composition and biological activities of the organic extracts of this plant. Therefore, methanolic extract of stem barks and leaves were prepared and submitted to chromatographic procedures. Besides, T. ramalhoi extracts biological evaluation showed antioxidant, antinociceptive and, anti-inflammatory activities. Usual chromatographic procedures of the active extracts permitted to isolate methyl 5-O-caffeoylquinate, apocynin C, cinchonains Ia and Ib, besides ß-sitosterol, stigmasterol and lupeol. The identification of the isolates was based on 13C and 1H NMR (1 D and 2 D) spectroscopic data and mass spectrometry. Although the flavalignans cinchonains Ia and Ib were previously isolated from T. catigua, this is the first occurrence of apocynin C in the Meliaceae family.

ABSTRACT

Em ectotérmicos, respostas defensivas a predadores geralmente dependem de relações de custo-benefício entre risco de morte e a energia necessária para fugir. Neste estudo, investigamos lagartos na Amazônia para testar a hipótese de que a distância mínima de aproximação de predadores (DAP) é influenciada pela temperatura e camuflagem. Nós testamos a hipótese de que estimativas de DAP para espécies com diferentes modos de termorregulação respondem diferentemente à temperatura e camuflagem. Nós amostramos 35 lagartos de uma espécie heliotérmica e uma não heliotérmica, para as quais simulamos um predador terrestre visualmente orientado. Usando um modelo linear de efeitos fixos, a temperatura afetou positivamente as estimativas de DAP, mas a camuflagem não contribuiu para o modelo. Usando um modelo linear de efeitos mistos, a camuflagem afetou negativamente as estimativas de DAP, independentemente de temperatura. Nossos resultados sugerem que alta exposição a predadores em hábitats abertos pode ser compensada por fuga rápida otimizada por altas temperaturas, e o baixo desempenho de fuga, usualmente causado por temperaturas relativamente mais baixas em habitats sombreados, pode ser compensado pela camuflagem. No entanto, a identificação do melhor preditor de DAP dependeu muito de considerar o modo de termorregulação nos testes de hipóteses, apesar de que os resultados obtidos por ambos os modelos de efeitos fixos e mistos podem ser relevantes para conservação.

ABSTRACT

BACKGROUND: The rising concern with environmental preservation has led to increasing interest in biodegradable polymer composites from renewable sources, such as cellulose and its derivatives. The use of nanocellulose is an innovative food packaging trend. DISCUSSION: This paper presents an overview and discusses the state of the art of different nanocellulose materials used in food and food packaging, and identifies important patents related to them. It is important to consider that before marketing, new products must be proven safe for consumers and the environment. CONCLUSION: Several packaging materials using nanocellulose have been developed and shown to be promising for use as active and intelligent materials for food packaging. Other nanocellulose products are under investigation for packaging and may enter the market in the near future. Many countries have been adjusting their regulatory frameworks to deal with nanotechnologies, including nanocellulose packaging.

ABSTRACT

Bacterial cellulose (BC) has been largely used in biomedical and technological fields. The use of agro-industrial byproducts as alternative source of carbon and nitrogen in culture media reduces the BC cost production, adds value to the byproducts and minimizes the environmental impact. In this study, the use of cashew apple juice and soybean molasses were evaluated to produce BC by Gluconacetobacter xylinus in comparison to the usual Hestrin and Schramm medium (HS). BC produced in static cultivation was characterized by X-ray diffraction, Fourier transform infrared spectroscopy and thermogravimetric analysis. The BC production (4.50 g L-1) obtained from the medium using cashew apple juice as carbon source (20 g L-1) with soybean molasses as nitrogen source (10 g L-1) was superior than HS medium (4.03 g L-1). Morphological analysis showed that bacterial celluloses produced with agro-industrial byproducts combined were similar to those found for the pellicle obtained from HS medium.

ABSTRACT

In ectotherms, defensive responses to predators usually depend on cost-benefit relationships between death risk and the energy required to flee. In this study we investigate Amazonian lizards to test the hypothesis that the minimum predator approach distance (PAD) is influenced by temperature and camouflage. We test the hypothesis that PAD estimated for species with different thermoregulation modes respond differently to temperature and camouflage. We sampled 35 lizards of a heliotherm and a non-heliotherm species, for which we simulated a terrestrial visually oriented predator. Using a fixed-effects linear model, temperature positively affected PAD estimates, but the camouflage did not contribute to the model. Using a mixed linear model assuming thermoregulation mode as a random factor, camouflage negatively affected PAD estimates, independently of temperature. Our findings suggest that high exposure to predators in open habitats may be compensated by rapid fleeing optimized by high temperatures, and low fleeing performance, usually caused by relatively low temperatures in shaded habitats, may be compensated by camouflage. However, identifying the best PAD predictor greatly depended on accounting for thermoregulation mode in hypothesis testing, although the results obtained by both fixed and mixed-effects models may be relevant for conservation.(AU)

ABSTRACT

BACKGROUND: Sepsis is a set of serious organic manifestations caused by an infection, whose progression culminates in exacerbated inflammation and oxidative stress, poor prognosis, and high hospital costs. Antioxidants used against sepsis have been evaluated, including essential oils such as ß-caryophyllene (BCP), and polyunsaturated fatty acids, such as docosahexaenoic acid (DHA). The aim of this study was to evaluate the anti-inflammatory activity of the association of these two compounds. RESULTS: Treatment with BCP-DHA, at a dose of 200 µL/animal, significantly inhibited the migration of neutrophils in a Cg-induced peritonitis model. After Staphylococcus aureus infection, in the groups treated with BCP-DHA there was a significant decrease in the total and differential count of leukocytes, increased expression of cytokines TNF-α and IFN-γ in treated groups, an increase of IL-4 and IL-5 in B/D and B/D + SA groups, and an augmentation of IL-6 and IL-12 groups in B/D + SA groups. Histological and bacterial analysis revealed lower neutrophil migration and lower bacterial load in the infected and treated groups. CONCLUSION: In general, the BCP-DHA association presented anti-inflammatory activity against two different models of acute inflammation and infection, showing promising potential as a therapeutic adjuvant in sepsis. © 2019 Society of Chemical Industry.

ABSTRACT

PURPOSE: Lactobacillus plantarum Lp62 is a lactic acid bacteria strain that has been isolated from cocoa beans and exhibited probiotic potential. The influence of oral administration of L. plantarum Lp62 on the growth of rat's pups; on yield, cytokines and milk composition was studied. METHODS: Lactobacillus plantarum Lp62 is a lactic acid bacteria strain that has been isolated from cocoa beans. It was administered daily by gavage to Wistar rats (n = 8), from the 7th day before delivery and for 20 days during lactation, in a concentration of 1.44 × 109 CFU/rat. The dam and pups were weighed and milk was collected at 12th and 19th day for determination of protein, triglycerides, cholesterol and lactose by colorimetric assays. TGF-ß1 milk levels were analyzed by ELISA. The mammary glands of rats were removed for histological analysis. To detect statistical differences between the groups, tests of mean differences at a significance level of 5% was performed. RESULTS: Supplementation with L. plantarum L62 resulted in significant higher weight of pups (p < 0.05), with similar weight on dams (p > 0.05). The milk yield was not altered by L. plantarum treatment, but the levels of protein, triglycerides and cholesterol were increased (p < 0.05), with no difference in lactose concentration (p > 0.05). Levels of TGF-ß1 were higher in the milk of L. plantarum treatment (p < 0.05). CONCLUSIONS: The treatment of dams at the end of pregnancy and lactation with L. plantarum Lp62 increased nutritional content of milk, probably contributing to the higher weight of the pups. The higher levels of TGF-ß1 in the milk, could promote immune benefits to the pups. Further studies in this field are needed to prove the potential use of L. plantarum Lp62 as a probiotic.

ABSTRACT

ABSTRACT Zootherapy (the use of the therapeutic potential of animals) is at least 6,000 years old, and has been kept active throughout generations until modern days. Animal fat is commonly used in the zootherapeutic folk medicine from South America, specially the green anaconda's fat, which is widely promoted as a natural medicine to treat wounds, even though there is no scientific evidence showing its efficacy. In this study we compared the total healing time and the proportional daily reduction of dorsal epithelial incisions in adult male Wistar rats treated with nitrofural (a commercial cicatrizing ointment) and with anaconda fat. We applied the treatments every two days and measured the incision diameter daily, during ten consecutive days. Differences among the groups in the total healing time and in the proportional daily reduction of the incision consistently showed that the fat-based treatment resulted in a faster healing process compared to the commercial ointment tested. The literature suggests that the efficacy of animal fat on healing may be primarily related to the presence of fatty acids, which have been widely demonstrated to be important for biochemical reactions involved in healing processes. Our findings are widely socially relevant, considering that traditional Amazonian communities that use anaconda fat in folk medicine do not have easy access to pharmacies and hospitals.


RESUMO Práticas ancestrais de zooterapia (uso das potencialidades terapêuticas da fauna) existem há pelo menos 6000 anos, e têm sido mantidas ao longo de gerações até os tempos modernos. Gordura de animais é comumente utilizada na zooterapia tradicional da América do Sul, e a gordura de serpentes sucuris é amplamente comercializada como cicatrizante natural, embora não existam evidências científicas que mostrem sua eficácia terapêutica. Neste estudo comparamos o tempo de cicatrização epitelial total e a redução proporcional diária de uma incisão dorsal em ratos Wistar machos adultos, entre um grupo controle, um grupo tratado com nitrofural (uma pomada cicatrizante comercial) e um grupo tratado com gordura de sucuri. Nós aplicamos os tratamentos a cada dois dias e medimos o diâmetro da incisão diariamente por dez dias consecutivos. Diferenças entre os grupos no tempo de cicatrização total e na redução proporcional diária da incisão consistentemente mostraram que gordura de sucuri teve ação cicatrizante mais eficiente que a pomada comercial testada. A literatura sugere que a eficácia de gordura animal em processos de cicatrização pode estar principalmente relacionada à presença de ácidos graxos, os quais têm sido amplamente demonstrados como importantes para reações bioquímicas envolvidas em processos de cicatrização. Os resultados têm ampla relevância social, considerando que as comunidades tradicionais amazônicas que utilizam a gordura de sucuris como zooterápico não têm acesso fácil a farmácias e hospitais.

ABSTRACT

Diabetes mellitus (DM) is an emerging global healthcare problem and its prevalence is increasing at an alarming rate. Despite improvements in both medical and pharmacological therapies, a complex medical condition may demand a diversified approach, such as: drug therapy, healthy diet and exercises, diabetes education programs, adherence to medical treatment and active participation of the patients in their lifestyle changes, such as stress management. The concept of mindfulness is here defined as the awareness that unfolds from the intention to attentively observe the current experience in a non-judgmental and non-evaluative way. This state of awareness can be enhanced through the use of mindfulness-based interventions (MBIs), which have been associated to many physical and psychological health indicators. The aim of this overview is to offer the rationale and potential benefits of mindfulness in the control of DM and its complications. METHODS: a narrative review of the current and updated literature available on online database and which came up using the terms "mindfulness" and "diabetes mellitus". Mindfulness-based Interventions (MBIs) can be seen as preventive and complementary interventions in DM, particularly for the relief of symptoms related to depression and anxiety in diabetic patients and also in the management of other factors, including mindful eating, physical exercises and treatment adherence. Although many studies only present research protocols, mindfulness seems to have beneficial effects on all aspects of diabetes, including incidence, control and complications. Furthermore, longer term and more carefully controlled trials are necessary in order to draw consistent conclusions on the beneficial role of MBIs on DM.

ABSTRACT

RESUMO: Neste trabalho, foi avaliado o desempenho de duas linhagens de Aspergillus niger (mutante 11T53A14 e selvagem C) previamente selecionadas como promissoras para a produção de lipases, utilizando meios de cultivo formulados a partir da torta de dendê (palmiste) e da borra alcalina do refino do óleo de dendê (borra de dendê), resíduos provenientes da agroindústria do óleo de dendê (palma) por fermentação em estado sólido (FES). Os experimentos de produção da enzima em FES foram conduzidos em colunas aeradas, incubadas em banho-maria a 32ºC com entrada controlada de ar não umedecido de 1,0vvm. Os melhores resultados foram obtidos com a cepa mutante A. niger 11T53A14 em meio contendo torta de dendê umedecida com solução sulfato de amônio (1,2%) e com a adição de 3% da borra de dendê. O valor máximo da atividade da lipase neste meio foi de 72,57U gss-1 em 48 horas. Esse valor foi 47,5% superior ao obtido no meio sem a borra de dendê. A comparação do desempenho da cepa mutante com a cepa selvagem mostrou que o meio composto por torta de dendê adicionado com sulfato de amônio e borra de dendê induziu ambas as linhagens a produzir lipases com bons níveis de atividade, além de reduzir o tempo de processo de fermentação.


ABSTRACT: In this paper it was evaluated the performance of two strains of Aspergillus niger (mutant 11T53A14 and wild type C) previously selected as promising for lipase production, from cultivation media formulated from palm kernel cake (kernel) and alkaline sludge from refining were evaluated palm oil (palm oil sludge), palm oil (palm) waste industrialization by solid state fermentation (SSF). Experiments of enzyme production in SSF were conducted in aerated columns, incubated in a water bath at 32°C with controlled inlet of 1.0vvm. The best results were obtained with the mutant strain A. niger 11T53A14 in medium containing palm kernel cake moistened with a solution of ammonium sulfate (1.2%) and with the addition of 3% of palm oil sludge. The maximum lipase activity in this medium was 72.57U gdw-1 in 48 hours and 47.5% higher than in the medium without sludge palm. A comparison of the performance of the mutant strain with the wild-type strain showed that the medium composed of palm kernel cake added with ammonium sulfate and blurs palm induced both strains to produce lipases with good activity levels and reduced the time of the fermentation process.

ABSTRACT

Neste trabalho, foi avaliado o desempenho de duas linhagens de Aspergillus niger (mutante 11T53A14 e selvagem C) previamente selecionadas como promissoras para a produção de lipases, utilizando meios de cultivo formulados a partir da torta de dendê (palmiste) e da borra alcalina do refino do óleo de dendê (borra de dendê), resíduos provenientes da agroindústria do óleo de dendê (palma) por fermentação em estado sólido (FES). Os experimentos de produção da enzima em FES foram conduzidos em colunas aeradas, incubadas em banho-maria a 32ºC com entrada controlada de ar não umedecido de 1,0vvm. Os melhores resultados foram obtidos com a cepa mutante A. niger 11T53A14 em meio contendo torta de dendê umedecida com solução sulfato de amônio (1,2%) e com a adição de 3% da borra de dendê. O valor máximo da atividade da lipase neste meio foi de 72,57U gss-1 em 48 horas. Esse valor foi 47,5% superior ao obtido no meio sem a borra de dendê. A comparação do desempenho da cepa mutante com a cepa selvagem mostrou que o meio composto por torta de dendê adicionado com sulfato de amônio e borra de dendê induziu ambas as linhagens a produzir lipases com bons níveis de atividade, além de reduzir o tempo de processo de fermentação.(AU)

ABSTRACT

The bark of Mimosa tenuiflora (Willd.) Poiret (Leguminosae family), popularly known as "jurema preta" in Brazil, is used by the population of Contendas of Sincorá (Bahia State, Brazil) for the treatment of coughs and wound healing. Thus, the aim of this study was to evaluate the antinociceptive and anti-inflammatory activities of the bark ethanol extract (EEMT) and solvent soluble fractions (hexane-H, DCM-D, EtOAc-E and BuOH-B) of the extract in vivo. Additionally, we synthesized 5,7-dihidroxy-4'-methoxyflavanone (isosakuranetin) and isolated the compound sakuranetin, and both compounds were also tested. The anti-inflammatory and antinociceptive assays performed were: writhing test; nociception induced by intraplantar formalin injection; leukocyte recruitment to the peritoneal cavity; evaluation of vascular permeability (Evans blue test); and evaluation of mechanical hypernociception (von Frey test). Production of TNF-α, IL-10, myeloperoxidase and the expression of ICAM-1 were also evaluated. Statistical analysis was performed by one-way ANOVA followed by the Bonferroni post-test (n = 8), with P < 0.05. The EEMT showed antinociceptive activities in writhing test (100-200 mg/kg), in the second phase of the formalin test (50-200 mg/kg), and in mechanical hypernociception (100 mg/kg). EEMT showed an anti-inflammatory effect by reducing neutrophil migration to the peritoneal cavity and in the plantar tissue detected by the reduction of myeloperoxidase activity (100 mg/kg), reduction of IL-10 levels and expression of ICAM-1 in the peritoneal exudate and the mesentery (100 mg/kg), respectively. The four soluble EEMT fractions showed good results in tests for antinociceptive (H, D, E, B) and anti-inflammation (H, D, E). Only sakuranetin showed reduction of the writhing and neutrophil migration (200 mg/kg). Thus, the EEMT and soluble fractions of M. tenuiflora bark demonstrated great antinociceptive and anti-inflammatory activities, as also sakuranetin. More studies should be conducted to elucidate the mechanism of action of this compound. To the best of our knowledge, this is the first report on the antinociceptive activity of the M. tenuiflora fractions and the bioactive isolated compound sakuranetin in vivo.

ABSTRACT

Background: Bipolar disorder is marked by alterations in coping skills which in turn impacts the disease course. Personality traits are associated with coping skills and for this reason it has been suggested that personality traits of patients with BD may have influence over their coping skills. Objective: To investigate possible associations between coping skills and personality in individuals with bipolar disorder (BD). Methods: Thirty-five euthymic subjects with BD were compared with 40 healthy controls. Coping skills were evaluated using Ways of Coping Checklist Revised and Brief-COPE. Personality traits were assessed by Neo Personality Inventory. MANCOVA was used for between groups comparison. Results: Regarding coping, individuals with BD reported more frequent use of emotion-focused strategies than problem-focused strategies, and high levels of neuroticism and low levels of extroversion and conscientiousness on personality measures. Neuroticism influenced negatively the use of problem-focused strategies, and positively emotion-focused coping. Conscientiousness influenced the use of problem-focused strategies in both groups. There was a significant difference between emotion focused coping and personality traits between BD and control groups. Discussion: Personality traits seem to modulate coping skills and strategies in BD which may be took into account for further interventions...


Contexto: O transtorno de humor bipolar (THB) é marcado por estratégias de enfrentamento, ou coping, que determinam comportamentos que podem influenciar negativamente o curso da doença. Traços de personalidade são altamente associados com estratégias de coping, portanto se faz a hipótese de que traços de personalidade influenciem as estratégias de coping de portadores de THB. Objetivo: Este estudo buscou investigar associações entre traços de personalidade e estratégias de coping em pacientes com THB. Métodos: Trinta e cinco participantes eutímicos diagnosticados com THB e 40 controles saudáveis participaram deste estudo. Estratégias de coping foram avaliadas com a Ways of Coping Checklist Revised and Brief – COPE – e traços de personalidade foram avaliados com o Neo Personality Inventory. Resultados: Participantes com THB possuíram padrão de estratégias de coping significativamente mais baseados na emoção. Em termos de traços de personalidade, participantes com THB tiveram significativamente mais características de neuroticismo e reduzidas características de extroversão e consciência. Foram encontradas associações positivas entre índices de neuroticismo e estratégias de coping baseadas em emoções e associações negativas com estratégias baseadas no problema. Conclusão: Traços de personalidade são fundamentais para as estratégias de coping de pacientes com THB, portanto traços de personalidade devem ser considerados alvos terapêuticos para a psicopatologia...
