Local Use and Management of Tasba (Senna obtusifolia) in the Traditional Food System of Sanguere Paul, North Cameroon

The purpose of this study is to examine the importance of the wild edible weed tasba (Senna obtusifolia) in Sanguéré Paul, Cameroon by examining how households use and manage the plant. This study found that local management of tasba is minimal compared to other traditional vegetables. Tasba was collected most frequently from en brousse or the communal, fallowed land which is often too degraded for traditional field crops to grow. Women subsistence farmers were closely involved with tasba as they are the ones responsible for food production within the family. Socioeconomic differences between women affects how they manage tasba and other vegetables to form a livelihood strategy to achieve food security within the family. Modifications and changes in management and use of tasba are influenced by time, proximity and income based on her perspective, preferences and resources available. Overall, tasba is an integral part of the traditional food system in Sanguéré Paul, and can play a role in the uncertain ecological and social setting of northern Cameroon.

Cytotoxic Granules In Distinct Subsets Of Cutaneous Lupus Erythematosus.

In cutaneous lupus erythematosus (CLE), the pathogenetic role of cytotoxic granules has been demonstrated in the subacute and discoid subtypes, which show interface dermatitis, but little is known about tumid (T)CLE, which does not show this interface dermatitis, and evolves with minimal epidermal changes. We studied cytotoxic T lymphocytes and cytotoxic granules in discoid (n = 21), subacute (n = 17), and tumid (n = 21) CLE samples. Skin sections were immunohistochemically stained for CD8, CD56, perforin, granzyme A, granzyme B, and granulysin. Inflammatory cells containing the four subtypes of cytotoxic granules were found in all the three CLE forms; however, only the TCLE group showed a positive correlation between the density of CD8+ cells and each subtype of cytotoxic granule-positive cells. In addition, only the TCLE group showed synergy between the densities of cells containing cytotoxic granule subtypes. Cytotoxic granules are important in the pathomechanism of TCLE. They may perform functions other than apoptosis, including maintenance of inflammation and dermal mucinous deposits in TCLE.

Relationship among malocclusion, number of occlusal pairs and mastication

This study evaluated the relationship among malocclusion, number of occlusal pairs, masticatory performance, masticatory time and masticatory ability in completely dentate subjects. Eighty healthy subjects (mean age = 19.40 ± 4.14 years) were grouped according to malocclusion diagnosis (n = 16): Class I, Class Class II-2, Class III and Normocclusion (control). Number of occlusal pairs was determined clinically. Masticatory performance was evaluated by the sieving method, and the time used for the comminute test food was registered as the masticatory time. Masticatory ability was measured by a dichotomic self-perception questionnaire. Statistical analysis was done by one-way ANOVA, ANOVA on ranks, Chi-Square and Spearman tests. Class II-1 and III malocclusion groups presented a smaller number of occlusal pairs than Normocclusion (p < 0.0001), Class I (p < 0.001) and II-2 (p < 0.0001) malocclusion groups. Class I, and III malocclusion groups showed lower masticatory performance values compared to Normocclusion (p < 0.05) and Class II-2 (p < 0.05) malocclusion groups. There were no differences in masticatory time (p = 0.156) and ability (χ2 = 3.58/p= 0.465) among groups. Occlusal pairs were associated with malocclusion (rho = 0.444/p < 0.0001) and masticatory performance (rho = 0.393/p < 0.0001), but malocclusion was not correlated with masticatory performance (rho = 0.116/p= 0.306). In conclusion, masticatory performance and ability were not related to malocclusion, and subjects with Class I, II-1 and III malocclusions presented lower masticatory performance because of their smaller number of occlusal pairs.

Experimental infections with Paracoccidioides brasiliensis obtained from armadillos: comparison to clinical isolates

Paracoccidioides brasiliensis causes paracoccidioidomycosis (PCM) that is one of the most prevalent systemic human mycoses in Latin America. Armadillos show a high incidence of PCM infection and could, therefore, be a natural reservoir for this fungus. In this study were compared the virulence profiles of isolates obtained from nine-banded armadillos (Dasypus novemcinctus) (PbT1 and PbT4) and isolates from PCM patients (Pb265 and Bt83). Pathogenicity was evaluated by fungal load and analysis of colony morphology. Immunity against the fungus was tested by delayed type hypersensitivity test (DTH) and antibody quantification by ELISA. The higher virulence of PbT1 and PbT4 was suggested by higher fungal load in spleen and lungs. Armadillo isolates and Bt83 presented a cotton-like surface contrasting with the cerebriform appearance of Pb265. All isolates induced cellular and humoral immune responses in infected BALB/c mice. DTH reactions were similarly induced by the four isolates, however, a great variability was observed in specific antibody levels, being the highest ones induced by Bt83 and PbT4. The present work confirms that armadillos harbor P. brasiliensis, whose multiplication and induced immunity in experimentally infected mice are heterogeneous, resembling the behavior of isolates from human PCM. This study reinforces the possibility that armadillos play an important role in the biological cycle of this pathogen.

A new bianthron glycoside as inhibitor of Trypanosoma cruzi glyceraldehyde 3-phosphate dehydrogenase activity

A phytochemical investigation of the ethanolic extract of stalks of Senna martiana Benth. (Leguminoseae), native specie of northeast Brazil, resulted in the isolation and spectroscopic characterization of a new bianthrone glycoside, martianine 1 (10,10'-il-chrysophanol-10-oxi10,10'-bi-glucosyl). Its identification was established by HRMS, IR and 2D NMR experiments. The evaluation of martianine trypanocidal activity was carried out against gliceraldehyde 3-phosphate dehydrogenase enzyme from Trypanosoma cruzi. Its inhibitory constant (Ki) is in the low micromolar concentration and it was determined by isothermal titration calorimetry to be 27.3 ± 2.47 µmol L-1. The non-competitive mechanism is asserted to be putative of the mode of action martianine displays against T. cruzi GAPDH. Results show that martianine has a great potential to become new lead molecule by inhibiting this key enzyme and for the development of new drugs against Chagas disease.

Portuguese version of the Delirium Rating Scale-Revised-98: reliability and validity

Objective To assess the validity and the reliability of the Portuguese version of the Delirium Rating Scale-Revised-98 (DRS-R-98). Methods The scale was translated into Portuguese and back-translated into English. After assessing its face validity, five diagnostic groups (n = 64; delirium, depression, dementia, schizophrenia and others) were evaluated by two independent researchers blinded to the diagnosis. Diagnosis and severity of delirium as measured by the DRS-R-98 were compared to clinical diagnosis, Mini-Mental State Exam, Confusion Assessment Method, and Clinical Global Impressions scale (CGI). Results Mean and rnedian DRS-R-98 total scores significantly distinguished delirium from the other groups (p < 0.001). Inter-rater reliability (ICC between 0.9 and 1) and internal consistency (alpha = 0.91) were very high. DRS-R-98 severity scores correlated highly with the CGI. Mean DRS-R-98 severity scores during delirium differed significantly (p < 0.01) from the post-treatment values. The area under the curve established by ROC analysis was 0.99 and using the cut-off Value of 20 the scale showed sensitivity and specificity of 92.6% and 94.6%, respectively. Conclusion The Portuguese version of the DRS-R-98 is a valid and reliable measure of delirium that distinguishes delirium from other disorders and is sensitive to change in delirium severity, which may be of great value for longitudinal studies.

Noninvasive Brain Stimulation With High-Frequency and Low-Intensity Repetitive Transcranial Magnetic Stimulation Treatment for Posttraumatic Stress Disorder

Objective: We aimed to investigate the efficacy of 20 Hz repetitive transcranial magnetic stimulation (rTMS) of either right or left dorsolateral prefrontal cortex (DLPFC) as compared to sham rTMS for the relief of posttraumatic stress disorder (PTSD)-associated symptoms. Method: In this double-blind, placebo-controlled phase II trial conducted between October 2005 and July 2008, 30 patients with DSM-IV-diagnosed PTSD were randomly assigned to receive 1 of the following treatments: active 20 Hz rTMS of the right DLPFC, active 20 Hz rTMS of the left DLPFC, or sham rTMS. Treatments were administered in 10 daily sessions over 2 weeks. A blinded rater assessed severity of core PTSD symptoms, depression, and anxiety before, during, and after completion of the treatment protocol. In addition, a battery of neuropsychological tests was measured before and after treatment. Results: Results show that both active conditions-20 Hz rTMS of left and right DLPFC induced a significant decrease in PTSD symptoms as indexed by the PTSD Checklist and Treatment Outcome PTSD Scale; however, right rTMS induced a larger effect as compared to left rTMS. In addition, there was a significant improvement of mood after left rTMS and a significant reduction of anxiety following right rTMS. Improvements in PTSD symptoms were long lasting; effects were still significant at the 3-month follow-up. Finally, neuropsychological evaluation showed that active 20 Hz rTMS is not associated with cognitive worsening and is safe for use in patients with PTSD. Conclusions: These results support the notion that modulation of prefrontal cortex can alleviate the core symptoms of PTSD and suggest that high-frequency rTMS of right DLPFC might be the optimal treatment strategy.

Immunization with pVAXhsp65 Decreases Inflammation and Modulates Immune Response in Experimental Encephalomyelitis

Background: A DNA vaccine (pVAXhsp65) containing the gene of a heat-shock protein (hsp65) from Mycobacterium leprae showed high immunogenicity and protective efficacy against tuberculosis in BALB/c mice. A possible deleterious effect related to autoimmunity needed to be tested because hsp65 is highly homologous to the correspondent mammalian protein. In this investigation we tested the effect of a previous immunization with DNAhsp65 in the development of experimental autoimmune encephalomyelitis (EAE), a rat model of multiple sclerosis. Methods: Female Lewis rats were immunized with 3 pVAXhsp65 doses by intramuscular route. Fifteen days after the last DNA dose the animals were evaluated for specific immunity or submitted to induction of EAE. Animals were evaluated daily for weight loss and clinical score, and euthanized during the recovery phase to assess the immune response and inflammatory infiltration at the central nervous system. Results: Immunization with pVAXhsp65 induced a specific immune response characterized by production of IgG(2b) anti-hsp65 antibodies and IFN-gamma secretion. Previous immunization with pVAXhsp65 did not change EAE clinical manifestations (weight and clinical score). However, the vaccine clearly decreased brain and lumbar spinal cord inflammation. In addition, it downmodulated IFN-gamma and IL-10 production by peripheral lymphoid organs. Conclusion: Our data demonstrated that this vaccine does not trigger a deleterious effect on EAE development and also points to a potential protective effect. Copyright (C) 2010 S. Karger AG, Basel

Ticks Infesting Wildlife Species in Northeastern Brazil With New Host and Locality Records

From September 2008 to March 2010, 397 ticks (315 larvae, 33 nymphs, 23 females, and 26 males) were collected from captive and free-living wildlife species in northeastern Brazil. Six tick species were identified, including Amblyomma auricularium (Conil) on Tamandua tetradactyla (L.),Amblyomma dubitalum Neumann on Hydrochaeris hydrochaeris (L.), Nectomys rattus (Pelzen) and T. tetradactyla, Amblyomma parvim A ragao on T. tatradactyla, Amblyomma rotundatum Koch on Boa constrictor L., Chelonoidis carbonaria (Spix), Kinosternon scorpioides (L.) and Rhinella jimi (Stevaux), Amblyomma cerium Koch on Bradypus variegatus Schinz, and Rhipicephalus sanguineus (Latreille) on Lycalopex vetulus (Lund). Nectomys rattus and T. tetradactyla are new hosts for A. dubitatum This study extends the known distribution of A. dubitatum in South America and provides evidence that its geographical range has been underestimated because of the lack of research. Four (A. dubitatum, A. parvum, A. rotundatum, and R. sanguineus) of six tick species identified in this study have previously been found on humans in South America, some of them being potentially involved in the transmission of pathogens of zoonotic concern.

Grupo informativo multidisciplinar em pr??-operat??rio de cirurgia card??aca: a informa????o e a multidisciplinariedade no hospital terci??rio como contribui????o ?? qualidade e ?? humaniza????o no atendimento p??blico de sa??de

A informa????o, atrav??s da Educa????o em sa??de, ?? elemento b??sico para que o cidad??o possa ser participante ativo do processo de busca de maior qualidade de vida, atrav??s do tratamento oferecido. Entretanto, a dificuldade de acesso ao sistema, a falta de vagas e o tempo de espera por uma cirurgia card??aca s??o fatores t??o emergenciais no setor, que o direito ?? um sistema de transmiss??o sistem??tica de informa????o sobre o tratamento nem sempre ?? levado em conta no pr??-operat??rio. Portanto, na busca de um atendimento mais humanizado ao paciente e seus familiares, torna-se importante n??o perder de vista que o cidad??o que procura o hospital traz uma complexidade que alia a doen??a a uma s??rie de vari??veis a serem vistas al??m do lado cl??nico, o que demonstra a necessidade de uma proposta multidisciplinar que possa oferecer informa????es sobre o processo a ser vivenciado no pr?? e p??s-cir??rgico, de forma a oferecer um tratamento ainda melhor

Estado, transnacionalidade e pol??ticas globais

Refletir sobre o Estado moderno requer a compreens??o do processo de globaliza????o, que se consolida por meio de atores transnacionais. Dessa maneira, ?? importante discutir a forma de intera????o entre o Estado e o setor n??o-governamental que, atuando como grupos de press??o, cria pol??ticas globais que debilitam gradualmente a centralidade do Estado e geram uma crise de governabilidade. Como as pol??ticas globais s??o realizadas em inst??ncias locais, a abordagem beyond the state se torna vulner??vel na medida em que o Estado ?? agente, se n??o definidor, implementador dessas pol??ticas. Para tanto, faz-se oportuna uma associa????o entre o Estado e o setor n??o-governamental, permitindo que um processo descentralizador e participativo favore??a os elementos para o redesenho do Estado.

A poesia nos livros didáticos : contribuição para um projeto educativo emancipatório

Este estudo tem por objetivo analisar poemas transcritos em livros didáticos do Ensino Médio adotados por escolas públicas, a partir do ano 2012, o estudo que as obras fazem dos poemas, o conteúdo das obras relacionado à poesia e à literatura e o trabalho que os professores fazem com os poemas em suas aulas, para verificar o possível potencial desestabilizador desses textos, relacionado à orientação dos discentes quanto à desigualdade e à exclusão social, em consonância com a ideologia de um Projeto Educativo Emancipatório sugerido por Boaventura de Sousa Santos. A pesquisa fundamenta-se nos pressupostos do “método crítico” de Bloch e as análises efetivadas possuem aspecto quantitativo e qualitativo. As informações dos docentes foram colhidas por meio de uma entrevista semiestruturada. Foi possível identificar que os poemas, em geral, nas duas obras, ocorrem em grande quantidade, contudo, em um número reduzido, se considerados aqueles que abordam situações de desigualdade e exclusão social; que há fragilidades importantes no estudo que as obras fazem deles, como uma pobre ou inexistente exploração do sentido textual, que dificulta um trabalho educativo crítico com os alunos; que os conteúdos relacionados à poesia e à literatura estão dispostos de forma fragmentada e desarticulada nas obras, comprometendo a aquisição de um conhecimento global pelos alunos; e que há, por parte dos docentes, um significativo trabalho com poemas, em geral, e um considerável trabalho com poemas do livro didático no sentido de orientar os alunos quanto à realidade social. Concluímos, então, que, apesar das inconsistências indicadas, nos poemas e nas obras, se os professores, conforme nos orienta Dalvi, encararem o livro didático como espaço de rasura e construírem novas visões sobre os seus conteúdos, de maneira a “trapacear” a “trapaça” que ele faz, podem torná-lo mais acessível e educativo para os alunos. Afinal, temos a potência da poesia do livro didático e a possibilidade dos docentes, que sinalizam para a possível tarefa de mostrar aos discentes situações de desigualdade e exclusão do passado, com o intuito de desestabilizá-los, no presente, em consonância com a ideia do supracitado Projeto.
