Several nutritional interventions are performed in order to reduce the impact of EO induced by exercise. Some studies suggest that mate tea (CM) have compounds, which can act as antioxidants reducing EO. The aim of this study was to evaluate the effect of CM induced under the EO after a single bout of aerobic exercise. Methods: We used male Wistar rats (50 days and 200g) distributed in four experimental groups: control (CON); mate tea (CM), Swimming (N); Swimming+mate tea (N + CM) . The CM and N+CM groups received CM diluted in distilled water at 96 ° C for five days, oropharyngeal route (50 mg / kg body weight, 0.5 mL). Both groups were adapted to the aquatic environment prior to experimental day, after a single swimming session, with 5% of body weight attached to the tail, until the animals reached exhaustion. Immediately after the state of exhaustion, peripheral blood was collected for further analysis. Results: The animals of the group N + CM showed improved resistance swimming compared to group C (p < 0.0001). No increase in lipid oxidative damage and production of lactate in group N + CM , compared to group N , may be attributed to the significant increase in plasma uric acid concentrations demonstrated in this study was observed . Conclusion: Therefore, the results indicate that consumption of CM may be natural strategy for improving aerobic exercise endurance and reduce the impact of EO induced by aerobic exercise.

Periodontal disease is the result of the interrelationship between microbiotic aggression and the host’s organic defence. Amongst the microorganisms involved in periodontopathies, Fusobacterium nucleatum is conspicuous by establishing a link between the initial and final colonizers, besides producing toxic compounds and adhering to the host’s cells. Control of bacterial biofilm can be achieved by use of chemical agents, many of which extracted from plants. Thus the object of this study was to evaluate the inhibitory activity in vitro of some teas, generally taken in a normal diet, on Fusobacterium nucleatum and your adherence to host’s cells. Minimum inhibitory and bactericidal concentrations were established and haemagglutinative test in microplaques was effected. It was ascertained that all plant extracts have inhibitory activity and that infusions of Camellia sinensis (black tea and green tea), Mentha piperita (mint) and Pimpinella anixem (aniseed) added to the bacteria/erythrocyte compound reduced significantly the adherence of microorganisms.

In recent decades there has been a significant increase in the consumption of legal and illegal drugs, and most of such compounds are able to induce dependence and this increase was observed mainly in females. This drug addiction increases susceptibility to several infectious agents, especially opportunistic microorganisms. The objective of this study was to evaluate the occurrence of opportunistic bacteria and yeasts in the mouth of drug addiction patients and non-addicted patients with different periodontal conditions. The study included 50 addiction patients and 200 non-addiction subjects. Intra and extraoral clinical examinations were performed and saliva samples were transferred to saline solution and the presence of members of the family Enterobacteriaceae, genera Enterococcus and Pseudomonas, as well fungi of the genus Candida was evaluated by culture. Samples were cultivated onto selective and non-selective media under aerobic conditions, at 37oC, for 24 -48 h. Identification of selected microorganisms were carried out through biochemical tests. Chi-square test was used to evaluate the data when three or more categories were involved. Higher detection frequencies of Candida species, family Enterobacteriaceae, E. faecalis, Pseudomonas sp. and P. aeruginosa in addiction patients were verified. It was found that patients addicted to both genders showed a higher occurrence of members of the Enterobacteriaceae, which were also associated with bone loss only in patients with drug addiction.

Water quality is very important for the health and the population welfare, and the public supply system must provide water quality and suffi cient quantity for the entire population. Water treatment stations, are the main way to obtain water quality. When this doesn’t occur, several problems can affect the population, in this case, using water with poor quality is a constant risk of emergence causing various diseases. The elimination of microorganisms in treated water reduces competition, encouraging the multiplication of chlorine resistant bacteria as Mycobacterium genus frequently isolated from treated and chlorinated water. Considering the lack of indication from examinations of mycobacteria routine laboratory for quality control of drinking water and other human uses, the objective was to verify the presence isolate and identify the environmental mycobacteria in the system water source surface of Araraquara - SP. We analyzed 40 water samples, distributed as follows: ten water gross collected at Station Water Treatment Plant (WTP), harvested after ten fi ltration; ten collected in the reservoir after chlorination and ten in the network distribution. Were recovered 43 isolates of mycobacteria. All isolates were subjected to PCR-PRA. The mycobacteria were identifi ed as M. lentifl avum, M. parafortuitum, M. genavense, M. gordonae, M. fortuitum, M. confl uent, M. duvalii, M. avium subspecies paratuberculosis and M. szulgai. With these results, was concluded that water is an important source of environmental mycobacteria probably related to several human diseases, suggesting the carrying out continuous monitoring of the microorganisms in the system drinking water.

We know the importance of treating water for human consumption because changes in the physicochemical and / or biological has been associated with various health problems, the quality of water intended for human consumption must meet potability standards established by governmental decree 518/2004. The aim of this study was to evaluate the quality of water supplied schools and daycare in the city of São Carlos - SP. We selected 31 schools and kindergartens, and at intervals of 3 months, two water samples taken at three different points - network, tank and fi lter - totaling 186 samples, with an interval of three months, to verify possible differences in sampling points and at different times. The samples were evaluated for the following parameters: presence of total coliform and fecal coliform / E. coli count of heterotrophic bacteria, determination of pH, fl uoride, free residual chlorine, turbidity and color. The largest number of samples outside the standard for coliform was coming from the fi lters and the network, heterotrophic bacteria in most samples was taken out of standard fi lters. In the physical-chemical analysis of samples as many non-standard pH occurred in the network, network, and fl uoride in the fi lter pair in the fi lter to free chlorine and turbidity in the reservoir. The parameter with a larger sample size was inadequate fl uoride. We need more attention to the conservation, cleaning and maintenance of building reservoirs and fi lters in schools and kindergartens of San Carlos, since the water was considered unfi t for consumption.

A doença de Dent é uma tubulopatia ligada ao X causada por mutações no gene que codifica o canal de cloro CLCN-5 e é caracterizada por proteinúria de baixo peso molecular, hipercalciúria, nefrocalcinose e insuficiência renal. Vários casos têm sido descritos, nos quais o único sintoma na apresentação foi proteinúria assintomática e glomerulosclerose global ou segmentar. A insuficiência renal nesses pacientes pode ser causada pela hipercalciúria e proteinúria persistente. Portanto, o inibidor da enzima de conversão da angiotensina e os tiazídicos poderiam ser úteis. O objetivo desta pesquisa é relatar os efeitos destas drogas em dois pacientes com doença de Dent tipo 1 com mutações novas. Neste relato não foram observadas correlações significativas entre dose de hidroclorotiazida e calciúria e entre enalapril e proteinúria. Este achado é importante, pois, sendo pacientes poliúricos, o uso destas drogas poderia prejudicar a função renal
