ABSTRACT
Exposure to paraquat is possibly involved with the development of several conditions, including neurodegenerative diseases, such as Parkinson's disease (PD). This condition is mainly characterized by the loss of dopaminergic neurons in the nigrostriatal pathway and the development of classical motor symptoms. Etiology includes exposure to environmental factors, such as the paraquat exposure, and inflammatory diseases may exacerbate paraquat neurotoxicity. The aim of the study was to investigate whether the exposure to paraquat associated with the presence of periodontal disease is able to induce motor and biochemical changes in rats similar to that observed in PD. Adult male Wistar rats were sent to ligature. After 48 h, they were sent to daily treatment paraquat (1 mg/kg/day; 2 mL/kg; intragastric) or vehicle for 4 weeks. Twenty-four hours after the last administration, the open field test was performed. The rats were euthanized and the left hemimandibles and striatum were dissected for the analysis of dopaminergic and inflammatory markers. Only the combination of periodontal disease model plus paraquat exposure induced motor impairments. Remarkably, the paraquat exposure increased the ligature-induced alveolar bone loss in hemimandibles. Moreover, only the combination of periodontal disease and paraquat exposure induced the loss of dopaminergic neurons and astrocyte activation in the striatum.

Diante da escassez de dados sobre a topografia e a sintopia das vísceras abdominopélvicas do tamanduá-bandeira (Myrmecophage tridactyla - Linnaeus, 1758), o presente estudo teve como objetivo elucidar essas características e compará-las com as demais espécies animais, mormente as domésticas. Utilizaram-se três espécimes, dois machos e uma fêmea, provenientes de doação da Polícia Militar Ambiental de Franca ao Laboratório de Anatomia Veterinária da Universidade de Franca, após óbitos por atropelamentos. Os animais foram fixados e mantidos em solução aquosa de formaldeído a 10%, seguidos de dissecação convencional das cavidades abdominopélvicas para posterior inspeção direta e descrição topográfica das vísceras, visando a análises comparativas com outras espécies, cujo posicionamento e cujas particularidades já são bem estabelecidos na literatura. Observou-se que a maioria das vísceras dessas cavidades possuem localização e sintopia similares aos animais domésticos, exceto os rins e os testículos. Diante da metodologia estabelecida e dos resultados obtidos, admite-se que mais espécimes de tamanduás-bandeiras, de ambos os gêneros, devam ser avaliados e registrados cientificamente, visando à confirmação dos dados da atual pesquisa e à preconização anatômica da cavidade abdominopélvica, visto que variações anatômicas individuais são passíveis entre animais da mesma espécie.(AU)
Objetivou-se avaliar a fauna vetorial e os aspectos ambientais e climáticos relacionados à transmissão das leishmanioses. Foi realizado um estudo eco-epidemiológico prospectivo de coleta sistemática de flebotomíneos e inquérito censitário sorológico canino em áreas de um município do Brasil. Para determinar a taxa de prevalência de LVC, foram examinadas amostras de sangue de 1752 cães. Na avaliação entomológica, foram instaladas 24 armadilhas luminosas em 12 residências distribuídas, instaladas no ambiente de peridomicílio e intradomicílio durante 12 meses. Para análise dos aspectos climáticos, utilizou-se a correlação simples de Spearman e para análise espacial foram utilizadas a Lógica Fuzzy e a Função K. A taxa de prevalência em cães foi de 4,1% e 7,1%. No estudo entomológico, foram capturados 431 flebotomíneos. A maior parte (74%) dos espécimes foi capturada no peridomicílio. Em relação à infecção natural, 5,6 % das amostras analisadas por biologia molecular apresentaram positividade à infecção por Leishmania spp.. Em 100% das amostras positivas, encontrou-se infecção por Leishmania infantum. Na análise espacial uma Área apresentou maior concentração de pontos de sobreposição de alta densidade de Lutzomyia longipalpis e cães sororreagentes, indicando maior risco na ocorrência concomitante dos dois eventos. Os resultados mostram que a interface parasito-reservatório-vetor está ativa nas áreas estudadas.(AU)

Recurrent hepatitis C (HCV) after liver transplantation (LT) is an important cause of morbidity and mortality. Antiviral treatment is recommended to avoid unfavorable outcomes. Direct-acting antivirals (DAA) have transformed HCV treatment, with higher efficacy and fewer side-effects than interferon-based therapies traditionally used. To evaluate DAA treatment outcomes at a Brazilian transplant unit, data of patients who finished HCV treatment at the Liver Transplant Unit of the University of Campinas were analyzed. Treatment consisted of sofosbuvir, daclatasvir, and ribavirin, for 12 or 24 weeks, according to the national guidelines. Fifty-five patients completed antiviral treatment and 54 had HCV-viral load results available. The majority of patients were male (78%), 58 years old on average, 65% had hepatocellular carcinoma (HCC) before LT, and 67% were interferon treatment-experienced. Most patients had HCV genotype 1 (65%), 35% had genotype 3, and started treatment on an average of 38 months after LT (range: 2-228). Fifty-eight percent were treated for 12 weeks and 42% for 24 weeks, using a mean dose of ribavirin of 10.1 mg/kg (4.2-16.1). There were no treatment interruptions due to serious side effects. The sustained virological response rate was 98%. Only one patient relapsed, a genotype 3 cirrhotic treated for 12 weeks. The average follow-up after starting antivirals was 20 months. There were no recurrences of HCC, but there was one rejection episode and one cirrhosis decompensation episode, both 12 weeks after treatment. DAA treatment is safe and effective in the post-LT setting and was not associated to HCC recurrence in the cohort studied.

BACKGROUND: Rhabdomyolysis is a syndrome characterized by impaired metabolic integrity of myocytes, causing the release of intracellular constituents into the circulation, and can be a serious side effect of drug intake. CASE REPORT: This report describes a unique case of rabdomyolysis secondary in which ciprofibrate, sirolimus, cyclosporine, and pegylated interferon-α in a liver transplant patient was used. A 47-year-old male liver transplant recipient in 2009, who had hepatitis C and incidental hepatocellular carcinoma, underwent immunosuppressive therapy (cyclosporine and sirolimus). The patient is currently in treatment for viral recurrence with pegylated interferon-α and ribavirin; he had a history of hypertriglyceridemia treated with ciprofibrate. He had development of severe and generalized myalgia and fever after the eighth application of pegylated interferon-α and increasing doses of cyclosporine. Laboratorial tests showed acute renal failure and significant increase in creatine kinase. Rhabdomyolysis secondary to interaction of fibrate-cyclosporine-pegylated interferon-α was postulated. CONCLUSIONS: Medical professionals should be aware of possible drug interactions and should monitor patients receiving these drugs.

A membrana de látex natural (NRL - Natural Rubber Latex), manipulada a partir do látex extraído da seringueira Hevea brasiliensis, tem apresentado grande potencial de aplicação no campo da biomedicina e dos biomateriais. Graças a sua biocompatibilidade e baixa taxa de rejeição, ela tem sido utilizada para próteses e enxertos, atuando como estimulante da angiogênese, adesão celular e barreira física a agentes infecciosos. Além dessas aplicações, as membranas são utilizadas como matriz de sistemas de liberação para avaliar o comportamento da liberação de fármacos e extratos de origem vegetal que apresentam propriedades medicinais. O sistema extrato-membrana tem como objeto de estudo uma nova abordagem dessas substâncias no tratamento de feridas visando à cicatrização e regeneração do tecido envolvido. Casearia sylvestris, conhecida popularmente como guaçatonga, pertence à família Salicaceae, conhecida na medicina popular pelos seus efeitos antiulcerogênicos, cicatrizantes, antiofídicos, anti-inflamatórios e antissépticos, propriedades já comprovadas por estudos. Trabalhos recentes demonstraram que a liberação controlada de fármacos e extratos utilizando membranas de látex natural é uma alternativa interessante e promissora para aplicações biomédicas. Assim, o objetivo deste projeto foi estudar a liberação do extrato de Casearia sylvestris incorporado à membrana de látex em soluções com diferentes valores de pH, com o propósito de estudar seu comportamento e sua liberação de forma controlada. A taxa de liberação do extrato do sistema extrato-membrana foi monitorada e analisada utilizando-se o método de espectroscopia ótica (UV). O pH básico age desestabilizando a membrana indicando que o polímero possui a habilidade de proteger o extrato de ser liberado em valores de pH ácidos, direcionando sua aplicação para o sítio de melhor absorção. Além disso, a liberação segue uma função bi-exponencial...
Natural Rubber Latex (NRL) membrane, made from latex extracted from the rubber tree Hevea brasiliensis, has shown great potential for use in the biomedicine and biomaterials area. Thanks to its biocompatibility and low rejection rate, it has been used for implants and grafts, acting as a stimulant of angiogenesis and cell adhesion and as a barrier against infectious agents. Besides these applications, the membranes are used as model release systems, to assess the release behavior of drugs and plant extracts that exhibit medicinal properties. The extract-membrane system represents a new approach to studying these substances, as aids to wound healing and tissue regeneration. Casearia sylvestris, popularly known as guaçatonga, belongs to the family Salicaceae, known in popular medicine for its anti-ulcerogenic, wound healing, anti-ophidian, antiinflammatory and antiseptic properties, all of which are proven by scientific studies. Recent studies have also shown that the controlled release of drugs and extracts from natural latex membranes is an interesting and promising process for biomedical applications. The objective of this project was thus to study the release of Casearia sylvestris extract incorporated into natural rubber membranes. The main concern was to study and optimize the controlled release of the extract at various pHs. The rate of release was monitored and analyzed by the method of optical spectroscopy (UV). Basic pHacts to destabilize the membrane, indicating that the polymer has the ability to protect the extract from being released at acidic pH values. The controlled release follows a bi-exponential function...

Ethanolic extract of Casearia sylvestris is thought to be antimutagenic. In this study, we attempted to determine whether this extract and casearin X (a clerodane diterpene from C. sylvestris) are protective against the harmful effects of airborne pollutants from sugarcane burning. To that end, we used the Tradescantia micronucleus test in meiotic pollen cells of Tradescantia pallida, the micronucleus test in mouse bone marrow cells, and the comet assay in mouse blood cells. The mutagenic compound was total suspended particulate (TSP) from air. For the Tradescantia micronucleus test, T. pallida cuttings were treated with the extract at 0.13, 0.25, or 0.50 mg/ml. Subsequently, TSP was added at 0.3mg/ml, and tetrads from the inflorescences were examined for micronuclei. For the micronucleus test in mouse bone marrow cells and the comet assay in mouse blood cells, Balb/c mice were treated for 15 days with the extract-3.9, 7.5, or 15.0 mg/kg body weight (BW)-or with casearin X-0.3, 0.25, or 1.2 mg/kg BW-after which they received TSP (3.75 mg/kg BW). In T. pallida and mouse bone marrow cells, the extract was antimutagenic at all concentrations tested. In mouse blood cells, the extract was antigenotoxic at all concentrations, whereas casearin X was not antimutagenic but was antigenotoxic at all concentrations. We conclude that C. sylvestris ethanolic extract and casearin X protect DNA from damage induced by airborne pollutants from sugarcane burning.

Trichophyton rubrum is a dermatophyte, which can cause infections in human skin, hair and nail. Pothomorphe umbellata (L.) Miq. (Piperaceae) is a native Brazilian plant, in which phytochemical studies have demonstrated the presence of steroids, 4-nerolidylcatechol, sesquiterpenes and essential oils. The objective of this study was to analyze the in vitro activity of extracts and fractions of P. umbellata on resistant strains of T. rubrum. The microdilution plate method was utilized to test Tr1, H6 and ΔTruMDR2 strains of T. rubrum; ΔTruMDR2 strain was obtained from H6 by TruMDR2 gene rupture, which is involved in multiple drugs resistance. The highest antifungal activity to all strains was observed for dichloromethane and hexane fractions of the 70% ethanolic extract which showed minimal inhibitory concentration (MIC) and minimal fungicide concentration (MFC) of 78.13 µg/mL. This antifungal activity was also obtained by 70% ethanolic extract, which presented MIC and MFC of 78.13 µg/mL to ΔTruMDR2, whereas the MIC values for Tr1 and H6 were 78.13 and 156.25 µg/mL, respectively. Our results suggest the potential for future development of new antifungal drugs from P. umbellata, especially to strains presenting multiple resistance.

Casearia sylvestris Swartz (Salicaceae) é uma espécie vegetal arbórea ou arbustiva, disseminada pelo território brasileiro e bastante utilizada em nossa medicina popular. Diversos diterpenos clerodânicos bioativos típicos do gênero Casearia foram isolados desta espécie (ex. casearinas e casearvestrinas). O objetivo principal deste trabalho foi avaliar a presença de diterpenos clerodânicos em diferentes órgãos de C. sylvestris, utilizando técnicas analíticas cromatográficas e espectroscópicas. Os extratos dos diferentes órgãos foram analisados por cromatografia em camada delgada, cromatografia líquida de alta eficiência com detector de arranjo de diodos e ressonância magnética nuclear de 1H. Nas análises cromatográficas foram utilizados diterpenos clerodânicos isolados de C. sylvestris como padrões, incluindo rel-19S-acetóxi- 18R- butanoilóxi- 18,19- epóxi -6S -hidróxi -2R- (2-metilbutanoilóxi) -5S, 8R, 9R, 10S -cleroda-3,13(16),14-trieno, isolado do caule pela primeira vez. Foram obtidos perfis fitoquímicos dos órgãos avaliados. Os resultados indicaram a presença de diterpenos clerodânicos em toda planta, prevalecendo em maior número nas folhas. Além disso, os resultados também indicam que em caules, flores e raízes há predomínio de diterpenos clerodânicos com padrão diênico diferente daqueles obtidos de folhas de C. sylvestris.
Casearia sylvestris Swartz (Salicaceae) is a tree or shrub distributed widely in Brazil, where it is used in popular medicine. Several bioactive clerodane diterpenes typical of Casearia have been isolated from this species (e.g. casearins and casearvestrins). The main objective of this study was to identify clerodane diterpenes in various organs of C. sylvestris, using chromatographic and spectroscopic analytical techniques. The extracts of the different plant parts were analyzed by thin layer chromatography, high performance liquid chromatography with diode array detector and 1H nuclear magnetic resonance. In the chromatographic analysis, clerodane diterpenes isolated from C. sylvestris were used as standards, including rel-19Sacetóxi- 18R- butanoilóxi-18,19- epóxi -6S -hidróxi -2R- (2-metilbutanoilóxi) -5S, 8R, 9R, 10S -cleroda-3,13(16),14- triene, isolated for the first time from the stems. Phytochemical profiles of the organs were produced, which indicated the presence of clerodane diterpenes in all parts of the plant, notably in the leaves. The results also suggest that the main clerodane diterpenes in the stems, flowers and roots had conjugated double-bond patterns that differed from those found in the leaves.

PURPOSE: To analyze the association between black people and left ventricular hypertrophy (LVH) in the absence of hypertension and/or other cardiopulmonar disease. METHODS: Data were collected from necropsies carried out in the Anatomopathologic Service (APS). Hospital Edgard Santos from 1970 to 1986, Salvador. It were included only subjects at ages > or = 20 years and free of hypertension and any cardiopulmonar disease. A LV wall > 1.6cm was considered as LVH (standardized criteria of the APS). Controls variables were age, sex, and absence of the mentioned diseases. It was used a case-control epidemiological study design and the association measured by "odds ratio" (OR) for no matched case-control study. RESULTS: From the 208 subjects studied, 48 (23.1%) had LVH. There was no difference in the frequency of right ventricular hypertrophy between cases and controls (p > 0.05). The mean of heart weight was higher for LVH cases (p < 0.001), but there was no evidence of association between blacks and LVH (OR = 1.05, p > 0.05 and confidence interval at 95% = 0.8, 1.31. The highest odds possible for the association in this study (assuming that all 3 LVH losses were black subjects) would be 1.5, also no statistically significant. CONCLUSION: In the absence of hypertension and other cardiopulmonar diseases, LHV is common in necropsies in Salvador, Brazil, with similar frequencies in blacks, whites and mullatos and seems not be a risk factor for hypertension in black people.
