This study aimed to evaluate the effect of muscle strengthening in the balance, mobility and quality of life (QoL) in individuals with Parkinson's disease (PD), and to check the correlation between muscle strengthening and QoL. Nine subjects belonging to both sexes, diagnosed with PD, participated in this study. Initially, they went through an evaluation of their balance and functional mobility through the Berg Balance Scale (BBS), the ­Timed Up and Go (TUG) test, and a QoL test through the Parkinson's Disease Questionnaire (PDQ-39). The subjects also performed a test for determining the maximum load (one-repetition maximum) for the muscle groups trained. After the normality and homogeneity of the data were verified, the Student's t-test and Spearman correlation test were carried out. A significance level of p<0.05 was considered. We verified an improvement in balance (p=0.008) and QoL (p=0.013), and a negative correlation between balance and QoL (evaluation: r=-0.65 and p=0.05, revaluation: r=-0.82 and p=0.005). It was concluded that muscle strengthening was efficient in the improvement of balance and QoL in individuals with PD.

OBJETIVO: Foi avaliar a frequência e os fatores de risco de quedas em mulheres na pós-menopausa. MÉTODOS: Estudo clínico, transversal, envolvendo 358 mulheres (idade entre 45 e 65 anos e amenorreia >12 meses) com tempo de pós-menopausa <10 anos. Os critérios de exclusão foram: doença neurológica ou músculo esquelético, vestibulopatias, hipertensão arterial não controlada, hipotensão postural, déficit visual sem correção, uso de medicamentos (sedativos e hipnóticos). A queda foi definida como mudança de posição inesperada, não intencional, que faz com que o indivíduo permaneça em nível inferior à posição inicial. Foram analisados o histórico de quedas (últimos 24 meses) e as características clínicas, antropométricas (índice de massa corpórea (IMC) e circunferência da cintura (CC)) e densidade mineral óssea. Na comparação segundo grupo de mulheres com e sem histórico de queda, foi empregado o Teste do Qui-quadrado ou Exato de Fisher e regressão logística com cálculo do odds ratio (OR). RESULTADOS: Entre as mulheres incluídas, 48,0% (172/358) referiram queda, com fratura em 17,4% (30/172). A queda ocorreu dentro de casa em 58,7% (101/172). A média de idade foi 55,7±6,5 anos, tempo de menopausa de 5,8±3,5anos, IMC 28,3±4,6 kg/m² e CC 89,0±11,4 cm. Foi observada maior frequência de tabagismo e diabetes entre as mulheres com histórico de quedas quando comparadas àquelas sem queda, de 25,6 versus 16,1% e 12,8 versus 5,9%, respectivamente (p<0,05). Na análise multivariada em função das variáveis clínicas influentes, o risco de queda aumentou com o tabagismo atual (OR 1,93; IC95% 1,01-3,71). Demais variáveis clínicas e antropométricas não influenciaram no risco de queda. CONCLUSÕES: Em mulheres na pós-menopausa inicial houve expressiva frequência de quedas. O tabagismo foi indicador clínico de risco para queda. Com o reconhecimento de fatores determinantes para queda, medidas preventivas são importantes, como a orientação de abolir o tabagismo.

Newcastle disease, salmonellosis and mycoplamosis are the most important infectious diseases in poultry. Toxoplamosis is a common disease in urban environment. The present study investigated serologic evidence of these diseases in captive and wildlife birds, with rapid plate agglutination test, haemagglutination inhibition test, and modified agglutination test. In a total of 117 blood serum samples, 20 showed the presence of Toxoplasma gondii, Mycoplasma gallisepticum, and Salmonella spp. antibodies. Amazona aestiva was the specie with the highest number of positive individuals (13/20). We also verified the first detection of T. gondii antibodies in birds of prey from Mivalgo chimachima and Rupornis magnirostris species.

The castor bean (Ricinus communis L.) is a tropical oilseed species, and the oil extracted from its seeds is one of the most versatile oils in the nature, showing various industrial uses. Even though it is a rustic species, the castor bean is subjected to several diseases such as the gray mold, caused by the fungus Amphobotrys ricini. Genetic breeding would be the best alternative for the disease control, but a long time is required to obtain resistant cultivars. Thus, the use of control strategies based on chemical, alternative or biological methods shows viable in the short term. The aim of this study was to investigate gray mold control efficiency, in castor bean crop, using chemical, alternative and biological methods. The pathogen control efficiency was evaluated both in vitro and in vivo using fungicides, essential oils and biological control agents. As regards the in vitro inhibition of the pathogen mycelial growth, the best treatments with essential oils were those based on C. martini and C. zeylanicum at all five tested concentrations. For both oils, the average diameter of colonies was 0.7 cm against 4.79 cm for the control treatment. For the fungicides, at all four tested levels, the most efficient active ingredients were methyl tiophanate, carbendazim, tebuconazole and iprodione. The ED50 of these fungicides was <1uL/L, yielding 100% mycelial growth inhibition at all concentrations. As to the inhibition of A. ricini conidium germination, the fungicides tebuconazole and chlorotanolyl were the best at all tested concentrations, and the average of germinated conidia with these fungicides was 0.0 and 0.15%, respectively, against 100% for the control treatment. In the field, treatment with the fungicide iprodione was the best for the disease control when compared to biological and alternative treatments. Under field conditions, the average disease severity for the treatment with iprodione was 15.76% against 95.81% for the inoculated control.

Five commercial rubber tree clones in a clonal nursery were assessed for resistance to powdery mildew, as well as for the disease fluctuation and its correlation with the climate conditions in the study period. For this assessment, a diagrammatic scale was developed from 150 central leaflets randomly collected at different ages and attack levels. Validation of scale was done by five assessors. Results indicated that all clones showed susceptibility to the pathogen, and the attack was higher for younger leaflets. According to the climate data, mild temperatures and relative humidity below 60% favored the epidemic.
