Comportamento de oviposição em Chrysomya megacephala (F.) (Diptera: Calliphoridae): distinção quantitativa frente a posturas prévias?

Chrysomya megacephala (Fabricius), has considerable medical, veterinary and forensic importance. In insects in general, the ability to track the food substrate is due to highly sensitive organs adapted for detecting odors, particularly in the case of blowflies, which is one of carcass main consumers. Eggs of blowflies are usually aggregated in function of the behavior of other pheromone mediated by females laying eggs in place on the same substrate. One of the main reasons for studying oviposition behavior is because it may indirectly affect individual qualification, population dynamics and community structure. It has been suggested that female blowflies can evaluate the number of eggs on a substrate, decreasing the size of oviposition in very saturated substrates with larvae or eggs leading to a lower intraspecific competition. The present study investigated the oviposition behavior of females of C. megacephala, and wished to consider whether they are able to distinguish quantitatively (size of the mass) eggs previously put into a place of posture and hence indicate whether there is a limit beneficial (to avoid competition among larvae) for its oviposition on the same substrate or if that place would already be saturated, requiring find another substrate without eggs or less for futures ovipositions. With 20 females and five males, five treatments were applied, repeated ten times and analyzed using the Mann-Whitney test. Each treatment consists in placing, inside the cage, a flask with 50g of ground beef and another one in the other side, with the same amount of substrate with a certain amount of prior oviposition for a period of 5 hours. The masses prior eggs were used 0.03 g, 0.05 g, 0.1 g, 0.2 g and 0.3 g (respectively, T1, T2, T3, T4 and T5). The other part of the work consisted in the use of a “Y” olfactometer, a device used to determine the choice of an invertebrate against... (Complete abstract click electronic access below)

Imagem corporal de adultos jovens e adultos idosos praticantes de dança

Introdução: Até o presente momento, nenhum estudo analisou a relação entre imagem corporal (IC) e dança em adultos jovens e adultos idosos. Dados dessa natureza podem auxiliar no entendimento da influência da dança na imagem corporal, bem como evidenciar seus benefícios em diferentes populações. Objetivo: Investigar a IC de adultos jovens e adultos idosos praticantes de dança. Método: Participaram deste estudo 10 adultos jovens e 10 adultos idosos do gênero feminino praticantes regulares de diversas modalidades de dança que responderam, voluntariamente, à versão brasileira do Body Shape Questionnaire (BSQ) adaptado pela autora para a dança e à Escala de Silhuetas para Adultos (ES) e foram questionados sobre seu peso e estatura para cálculo do Índice de Massa Corporal (IMC). O grupo controle foi composto por 10 adultas jovens e 10 idosas fisicamente ativas que responderam à versão brasileira do BSQ (sem adaptação) e à Escala de Silhuetas e também foram questionados sobre seu peso e estatura. Na análise estatística final, para a comparação entre os grupos foi utilizado o Mann-Whitney Test. Resultados: No instrumento BSQ, para as variáveis idade e dança, o Mann- Whitney Test não apontou diferença significativa (p≤0,05). No instrumento ES, para as variáveis idade e dança, o Mann-Whitney Test também não apontou diferença significativa (p≤0,05). Conclusão: Tanto a atividade física quanto a dança apresentaram ser um bom instrumento para melhora da IC. Entretanto, considera-se de extrema relevância a realização de mais pesquisas nesta área. Uma amostra maior também poderia confirmar os dados já encontrados neste estudo e na literatura, em termos de significância estatística

Efeito do treinamento com pesos nos distúrbios do sono e na qualidade de vida de pacientes com demência de Alzheimer

The Alzheimer's dementia (AD) is the most prevalent form of dementia in the elderly. Among the harmful changes arising from the DA, there may be sleep disturbance and impaired quality of life. Physical activity is an important non-pharmacological feature that would provide positive effects for the treatment of disease. However, there are still few studies that clarify the effects of resistance training in this population. Thus, the present study has as objective analyzes the effects of the resistance training in sleep disturbance and quality of life of patients with AD. Participated in this study 22 patients with clinical diagnosis of AD divided into two groups: Training Group (TG) and Social Interaction Group (SIG). The subjects of TG underwent a resistance training protocol, appropriate to the individual conditions, during three days no consecutive in the week, with duration of 60 minutes each session, for 16 weeks. The SIG won't participate in any systematized physical activity, but they realized other activities, such as reading, poetry, hiking and painting, among others. This protocol also was realized three times in week for 16 weeks, with duration of 60 minutes each session. Both groups were assessed at the beginning of the program and after 16 weeks. For the assessment of sleep disturbance was used the Mini Sleep Questionnaire and to assess of quality of life was used the Scale for Assessment of Quality of Life in Alzheimer's disease (QL), versions: patient, caregiver, family and the final score. Due to the scalar nature of the data and small sample, all variables were analyzed by nonparametric statistics. The U-Mann Whitney test, Wilcoxon test and Spearman correlation test was used, except for the Modified Baecke... (Complete abstract click electronic access below)

Total bacterial counting and the response to treatment of bacterial vaginosis with metronidazole

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

Dental caries in children participating in a dentistry for infants program

To assess the impact of the "Dentistry for Infants" early dental care program run by Jacareí County (SP) by comparing the caries of individuals participating and not participating in this program. Methods: In total, 300 children between 0 and 48 months old were assessed in the following two groups: infants not participating in the program (G1, n = 100) and infants participating in the program (G2, n = 200). Each group was further divided according to age in subgroups of 0 to 24 months and 25 to 48 months. All children were clinically assessed for carious lesions using the visual-tactile method. The data were statistically analyzed using a paired Student's t-test, Mann-Whitney test, and c 2 test at a 5% significance level. Results: There was a significant difference in the prevalence (P) and mean index of deciduous teeth (deft) (C) that were decayed, indicated for extraction and filled, and the highest values were observed in G1 (p < 0.0001). The values were as follows: PG1, 73%; PG2, 22%; CG1, 3.45 ± 3.84; and CG2, 0.66 ± 1.57. Conclusion: Participating in the program positively impacted the infants' oral health.

Atividade antimicrobiana de enxaguatórios bucais sem álcool à base de clorexidina sobre candida albicans

The aim of this study was to evaluate the antimicrobial activity of alcohol-free mouthwashes on Candida albicans. Twenty clinical isolates of C. albicans and one reference strain (ATCC 18804) were evaluated after exposure to two 0.12% chlorhexidine-based and alcohol-free (“Ca” and “Or”) in comparison to gluconate chlorhexidine with ethanol (positive control). The maximum inhibitory dilution (MID) and maximum fugal dilution (MFD) were determined by the microdilution method. Twelve serial dilutions (from 50 to 0.02%) were prepared in duplicate. Then, 100 µL of C. albicans suspension (106 cells.mL–1) were added to the wells. After incubation (37 °C/24 hours), MID was determined by reading the optical density. For MFD determination, the content of the wells were plated on Saouraud agar. For MID, there were no differences between groups Or and control, but Ca group showed a MID statistically higher (Kruskal-Wallis, p = 0.0012). For MFD, there were no differences between Ca and control (Mann-Whitney test, p = 0.1631). It can be concluded that Ca group showed a fungicid activity against C. albicans similar to the control, but lower fungistatic activity when compared to the control. Group Or showed only a fungistatic action similar to control.

Diagnóstico radiográfico diferencial das reabsorções radiculares internas e externas entre especialistas em endodontia e clínicos gerais

Objectives: The objective of this study was to evaluate the ability of endodontists and general practioners to perform the differential radiographic diagnosis between internal and external root resorptions, using digitized periapical radiographs. Methods: Thirty periapical radiographic images of external and internal resorption were selected. The evaluators were comprised of 15 endodontists and 29 general practitioners who answered a questionnaire with the following question: “What type of resorption in the following radiographics do you diagnose?” (1) Inflammatory external root resorption. (2) Internal root resorption. Statistical analysis was performed based on the Mann-Whitney test, with significance level of 5%. Results: There was no statistically significant difference in the percentage of correct answers from specialists in endodontics and general practitioners. Conclusions: Both groups demonstrated satisfactory skill in the radiographic interpretation of internal and external resorption and there was a higher percentage of correct diagnosis of internal resorption than the external.

Bond strenght of dental adhesive systems irradiated with ionizing irradiation

The aim of the present paper was to determine the effect of different types of ionizing radiation on the bond strength of three different dentin adhesive systems. Materials and Methods: One hundred twenty specimens of 60 human teeth (protocol number: 032/2007) sectioned mesiodistally were divided into 3 groups according to the adhesives systems used: SB (Adper Single Bond Plus), CB (Clearfil SE Bond) and AP (Adper Prompt Self-Etch). The adhesives were applied on dentin and photo-activated using LED (Lec 1000, MMoptics, 1000 mW/cm2). Customized elastomer molds (0.5 mm thickness) with three orifices of 1.2 mm diameter were placed onto the bonding areas and filled with composite resin (Filtek Z-250), which was photoactivated for 20 s. Each group was subdivided into 4 subgroups for application of the different types of ionizing radiation: ultraviolet radiation (UV), diagnostic x-ray radiation (DX), therapeutic x-ray radiation (TX) and without irradiation (control group, CG). Microshear tests were carried out (Instron, model 4411), and afterwards the modes of failure were evaluated by optical and scanning electron microscope and classified using 5 scores: adhesive failure, mixed failures with 3 significance levels, and cohesive failure. The results of the shear bond strength test were submitted to ANOVA with Tukey's test and Dunnett's test, and the data from the failure pattern evaluation were analyzed with the Mann Whitney test (p = 0.05). Results: No change in bond strength of CB and AP was observed after application of the different radiation types, only SB showed increase in bond strength after UV (p = 0.0267) irradiation. The UV also changed the failure patterns of SB (p = 0.0001). Conclusion: The radio-induced changes did not cause degradation of the restorations, which means that they can be exposed to these types of ionizing radiation without weakening the bond strength.
