Adopting a healthy lifestyle it is critical for the prevention of high blood pressure and is an indispensable part of the treatment of those with hypertension. High levels of physical activity and greater fitness are associated with reduced incidence of hypertension. However until the beginning of the 1990 decade, the resisted exercise was not inclued at the internacionals statements for people with heart disease. Fortunately, in the past few years, this type of exercise started to take into account as a possible strategy for the first and second prevention of diferents cardiovascular diseases. The aim of this study it is to evaluate, through a systematic review, the contribution of the resisted exercise on the cardiovascular responses in hypertensive male adults. Twenty eight articles were pre-selected for this study, four attend to the requirements. The results were not consistent in this review, only the diastolic blood pressure demonstrated decrease in three of the four studies, in circuit protocol as much as in the conventional protocol. Otherwise one study proved an increase in the VO2max, wich is an important data, because it is an anaerobic exercise and, an improve was not expected. An other article analised the harm issues of the Valsalva manouvre, where it was presented the maximum blood pressure values (345/245 mmHg) and evidences of lower blood pressure rises in the intra-arterial, intrathoracic and intra-abdominal pressures when the exercise was performed without the manouvre, enhancing the necessity to avoid the use of this manouvre in hypertensive individuals.

The aim of this study was to investigate whether aerobic capacity (VO2max) would be modified by antihypertensive therapy in elderly and middle-age women after 12 weeks of exercise training. The volunteers were divided in two groups: normotensive (n=14) and hypertensive (n=14). Aerobic exercise was performed for 3 days/week, during 60 minutes, for 12 weeks with an intensity of 50-70% rest heart hate. Anthropometric parameters (weight and height), body fat index, % of fat mass, cardiopulmonary evaluation to calculated VO2max and a cardiovascular evaluation with blood pressure and rest heart hate were evaluated at baseline and after training program. At the end of study abdominal circumference and Borg scale were also evaluated. Our findings showed the aerobic program of 12 weeks was effective to reduce diastolic blood pressure in both groups. Systolic blood pressure was reduced only hypertensive group. No evidences were found the aerobic capacity was affected by hypertensive therapies. In conclusion, the aerobic program for 12 weeks was effective to reduce blood pressure and there was no influence of antihypertensive therapy on the aerobic capacity in this particular population.

Objective: To evaluate, by means of a microbiologic study, two kinds of soaps suggested by surgeons for presurgical handwashing, comparing a well-known antibacterial soap with a new soap formulated from vegetable oils. Materials and methods: Ten volunteers performed handwashing according to previously established protocols for routine antisepsis in operating rooms using 3 different soaps: a common, commercially marketed soap, serving as the control group (Group 1), with no antibacterial characteristics; a soap with 2% chlorhexidine (Group II); and a new soap formulated from vegetable oils at a concentration of 20%, known as surfactant, which was designed by the Chemistry Institute (Unesp/Araraquara – Grupo de Materiais Fotônicos) (Group III). The microbiological samples were collected immediately before and after handwashing and one hour later with the volunteer wearing surgical gloves. Results: ANOVA revealed that the following significant differences are found in the number of bacterial colonies: between soap types (a smaller number of colonies in the Group II soap), between periods (reduction in the number of colonies in the Group II soap), and the significant effect of the soap versus time interaction. Conclusion: The 2% chlorhexidine soap performed better in reducing the number of bacterial colonies on the hands immediately after handwashing and after one hour with the use of surgical gloves, when compared to the 20% surfactant soap.

The use of new substrates, which do not lead to extinction of important species such as xaxim, has gained special attention to the cultivation of ornamental and exotic plants. This study aimed to evaluate the potential of using corn cob as substrate for growing orchids. Thus, we used plants of Laelia pulcherrima grown in pine bark (control) and corn cob. We evaluated the development and physicochemical characteristics. We assessed also the benefit of fertilization for the development of this species in both substrates. The corn cob had higher nutrient contents and higher water retention capacity than pine bark, as well as pH and porosity more appropriate. Plant development of L. pulcherrima on the cob was comparable to that obtained with pine and the use of fertilizer promoted the best growing, especially when the substrate used was the cob. Thus, it is recommend to use the same for the cultivation of this orchid.

Na busca de novos recursos genéticos capazes de produzir enzimas celulolíticas a baixas/médias temperaturas, o continente Antártico vem demonstrando ser um ambiente bastante promissor. Neste contexto, o objetivo do presente trabalho foi avaliar a influência de diferentes fatores na produção de celulases por fungos filamentosos isolados de amostras da Antártica visando otimização do processo possível aplicação das mesmas na produção de etanol de segunda geração. Foram utilizados os fungos L1-1 e E5B da Central de Recursos Microbianos da UNESP (CRM-UNESP) os quais foram previamente selecionados devido ao potencial celulolítico. O delineamento experimental foi utilizado para analisar a influência de variáveis independentes na produção enzimática. A quantificação da celulase foi realizada pelo método do ácido dinitrosalicílico (ADNS). Antes de iniciar à aplicação dos planejamentos experimentais, foram adotadas estratégias para tentar minimizar e otimizar ao máximo o potencial dos isolados, as quais resultaram no estabelecimento da melhor agitação e a temperatura para a produção de celulase em 150 rpm e 20°C, para os dois isolados estudados. Inicialmente os fungos E5B e L1-1 apresentavam suas produções enzimáticas em 0,233U/mL e 0,342U/mL, respectivamente (antes da aplicação dos desenhos experimentais). Durante a condução do planejamento experimental do tipo Plackett&Burman(PB), foi verificada a preferência dos isolados pela fonte de carbono glicose, com efeito significativo na produção de celulases para os dois isolados. Tendo em vista o seu elevado custo comercial, foram realizados estudos com a sacarose, uma fonte de carbono alternativa e mais barata, bem como indutores enzimáticos. Após três planejamentos experimentais do tipo PB, foi selecionado o isolado L1-1 como o melhor produtor da enzima celulase. Após a condução de um quarto planejamento experimental do tipo Fatorial Fracionado 24-1, as...
