Introduction: Some losses resulting from aging can be minimized with the practice of resistive exercises. Objective: To analyze the effects of resistive exercises on flexibility, mobility, muscle strength and balance in the elderly. Method: Twenty elderly individuals were divided between an activity group (AG, n=10; 66.1±6.35 years) and a control group (CG, n=10; 65.4±7.54 years). Mobility, flexibility, muscle strength and balance were evaluated. The AG participated in the training for 13 weeks (one-hour sessions, twice a week). The Wilcoxon non-parametric test (intra-group analysis) was used to analyze the data. A significance level of 5% (p<0.05) was adopted. Results: After training, the AG presented better mobility, lower limb muscle strength, and balance, but no difference in flexibility. Conclusion: The present study allows us to conclude that resistive exercises were able to improve mobility, lower limb muscle strength and balance in elderly individuals.

Introduction: the improvements on the health area increased the brazilians life expectative. Because of it, more people becomes elder, passing through various common processes of aging, as the balance decrease. Resulting form this the risk of fall increase, and this has a negative impact on the quality of life. As more people become elder the institutionalization tax increase. Objectives: compare the balance and quality of life between institutionalized and non-institutionalized elders; correlate the Berg Balance Scale (BBS) with the Timed Up and Go test (TUG) and with the questionnaire “The Medical Outcome Study 36 – Item Short-Form Health Survey” (SF-36). Methods: were evaluated 20 elders, ten institutionalized (GI) and ten non-institutionalized (GNI). To the balance assessment were used the BBS and the TUG, the quality of life was evaluated using the SF-36. The signifi cance level was set to 5% (p<0,05). The GraphPad Prism 5# was used to analyze the data. To identify the distribution of the data was applied the Shapiro-Wilk test. In the comparison between groups, the normal distributed data were analyzed with the Unpaired Student t test. The non-normal distributed data were analyzed with the Mann-Whitney non-parametric test. The correlations were analyzed with the Pearson (normal data) and Spearman’s (non-normal data) tests. Results: the age average for each group was 72,8±8,36 years (GI) e 67,4±3,53 years (GNI). The GNI had a better performance than the GI in the BBS (*p=0,0017) as in the TUG (*p<0,0002). There wasn’t difference between the quality of life. There was correlation between EEB and TUG (-0,8907 for the GI and -0,7180 for the GNI) and between EEB and the functional capacity domain from the SF-36 (0,7657). Conclusion: the non-institutionalized elders presented best balance. It was found good correlation between TUG and BBS. In the studied sample, to be institutionalized didn’t infl uenced the quality of life.

Accidents involving insects of the Hymenoptera order occur very often with both human beings and domestic pets and, in Brazil, they include aggravated cases with Africanized bees (Apis mellifera). The aggravation of deforestation and the lack of awareness regarding the subject are factors that contribute to the rise of the number of bees in the urban environment. This fact has been causing several derangements among the population because, once these insects are bothered, they become very aggressive. Considering the risks to population and the great amount of accidents that could be avoided, the development of researches with the goal of determining repelling substances is rather important. Therefore, this research evaluated the repelling action of essential natural oils obtained from rosemary (Rosmarinus oficinalis), lemongrass (Cymbopogon citratus), thyme (Thymus vulgaris), cedar (Juniperus virginiana), clove (Syzygium aromaticum) and mint (Mentha piperita) on A. mellifera Africanized worker bees in both semi-field and aggressiveness tests. Among the evaluated composites, the lemongrass, mint and clove essential natural oils presented a grater repelling effect, inhibiting the bees’ visitation to the managed feeders almost completely. The cedar essential natural oil was the least effective composite, and the rest of the tested oils presented satisfactory repellency, which became less effective over time, according to non-parametric Mann-Whitney test. However, further tests showed that only the lemongrass essential natural oil caused a less aggressive response from the bees, which can confirm the repelling power of this composite. This way, according to the results obtained through this research, lemongrass presents a greater potential to the development of effective repelling formulas against Africanized bees (Apis mellifera)

Objective: To evaluate if the total bacterial count of vaginal samples with bacterial vaginosis assessed by flow cytometry influences the response to treatment with metronidazol. Methods: In this cross-sectional study, 273 low-risk reproductive aged women were enrolled. Vaginal samples were taken to evaluate the pattern of vaginal flora according to Nugent’s criteria, as well as the presence of trichomoniasis and candidosis. Cases identified of bacterial vaginosis were treated with metronidazole and controlled after 45 days. Cervical infection by Chlamydia trachomatis and Neisseria gonorrhoeae were also assessed. Flow cytometry for total bacterial counting was performed in propidium iodide stained cervicovaginal samples, using fluorescent beads at a known concentration. Non-parametric Mann-Whitney test was used to compare total bacterial count between groups of interest, at p<0.05. Results: From the total of 273 women enrolled, 50 were excluded as they presented at least one of the infections investigated. Bacterial vaginosis was detected in 79 women (35.4%), of which 33 (41.8%) returned for re-evaluation after treatment, being 21 cases successfully treated and 12 with persistent abnormal vaginal flora. Flow cytometric data showed that total bacterial counting does not differ between normal flora and bacterial vaginosis samples (p=0.14). Also, no difference was found between the cases of treated and persistent bacterial vaginosis (p=0.48). Conclusion: Total bacterial counting does not influence the response to metronidazole treatment of bacterial vaginosis

Composite resins are materials that can present color changing when exposed to pigments. Objective: The aim of this study was to evaluate, in vitro, the color changing of composites after immersion in different substances for different periods. Material and methods: Two microhybrid composite resins: Charisma (Heraeus – Kulzer) and Opallis (FGM) were used. Red wine and acai pulp were also used as immersion medium. For this study, 32 specimens with 10 mm of diameter and 2 mm of thickness were used, divided into 4 groups: Group 1 – Opallis composite immersed in red wine solution; Group 2 – Opallis composite immersed in acai berry pulp solution; Group 3 – Charisma composite immersed in red wine solution; Group 4 – Charisma composite immersed in acai berry pulp solution. The specimens were evaluated in the following time periods: T0 – baseline, T1 – 24 hours, T2 – 48 hours, T3 – 72 hours and T4 – 96 hours. For the assessment of staining, a spectrophotometer for colorimetry was used (Color Guide 45 / 0, PCB 6807 BYK-Gardner Gerestsried GmBH, Germany), and the values obtained were transferred to a computer and recorded according to CIELAB system. Results: The data were evaluated using Kruskal- Wallis non-parametric tests with the following mean values for the immersion periods of 24, 48, 72 and 96 hours, respectively: G1 – 7.35, 7.84, 9.04,10.48; G2 – 2.92, 4.15, 4.30, 4.64; G3 – 3.14, 7.35, 8.13, 8.43, G4 – 4.49, 5.99, 6.92, 6.76. Conclusion: Red wine showed a higher tendency toward altering the composite color than acai berry pulp. In addition, no significant difference was found concerning to the behavior of the two composite resins. Concerning to the immersion time periods, significant differences were only observed among the groups in the 24 hour time period.

Aim: To evaluate the dental development of Brazilian children and adolescents with cleft lip and palate. Methods: The sample consisted of 107 panoramic radiographs of children and adolescents with cleft lip and/or palate (cleft group) and 107 panoramic radiographs of children and adolescents without cleft lip and/or palate (control group), with chronological ages ranging from 6 to 15 years, matched in gender and chronological age within 60 days. Radiographs were digitized and masked and dental age was assessed using the method described by Demirjian et al. (1973). Three trained examiners conducted the assessments. Each examiner evaluated the radiographs three times. Data were statistically analyzed using non-parametric tests and univariate linear regression (p<0.05). Results: The dental age was overestimated in relation to the chronological age in both groups (p<0.0001). Compared to the control group, there was a delay in the dental age in the cleft group of 0.17 years (2.1 months). However, no statistically significant difference in the dental age between the cleft and the control group was found even when considering the different cleft types (p=0.152). Conclusions: There was no statistically significant difference in the dental age between the cleft and the control groups. The evaluation of dental development in individuals with cleft lip and palate should be approached in the same way as in individuals without clefts, with a focus on the individualization of diagnosis and treatment planning.
