Acute auditory stimulation with different styles of music influences cardiac autonomic regulation in men

No clear evidence is available in the literature regarding the acute effect of different styles of music on cardiac autonomic control. The present study aimed to evaluate the acute effects of classical baroque and heavy metal musical auditory stimulation on Heart Rate Variability (HRV) in healthy men. In this study, HRV was analyzed regarding time (SDNN, RMSSD, NN50, and pNN50) and frequency domain (LF, HF, and LF / HF) in 12 healthy men. HRV was recorded at seated rest for 10 minutes. Subsequently, the participants were exposed to classical baroque or heavy metal music for five minutes through an earphone at seated rest. After exposure to the first song, they remained at rest for five minutes and they were again exposed to classical baroque or heavy metal music. The music sequence was random for each individual. Standard statistical methods were used for calculation of means and standard deviations. Besides, ANOVA and Friedman test were used for parametric and non-parametric distributions, respectively. While listening to heavy metal music, SDNN was reduced compared to the baseline (P = 0.023). In addition, the LF index (ms(2) and nu) was reduced during exposure to both heavy metal and classical baroque musical auditory stimulation compared to the control condition (P = 0.010 and P = 0.048, respectively). However, the HF index (ms(2)) was reduced only during auditory stimulation with music heavy metal (P = 0.01). The LF/HF ratio on the other hand decreased during auditory stimulation with classical baroque music (P = 0.019). Acute auditory stimulation with the selected heavy metal musical auditory stimulation decreased the sympathetic and parasympathetic modulation on the heart, while exposure to a selected classical baroque music reduced sympathetic regulation on the heart.

Effects of β-(1→3,1→6)-d-glucan and density of diets on the blood profiles of immunologically challenged weaned piglets

An experiment was conducted to evaluate the effects of two levels of the β-(1→3,1→6)-d-glucan (0 and 500ppm) from yeast Saccharomyces cerevisiae and two levels of energy (3300 and 3450kcalMEkg(-1)) on the hematological, immunological and, biochemical profiles of thirty-six 21-days-old weaned piglets, challenged with 150μgkg(-1) of BW lipopolysaccharide (LPS) from Escherichia coli serotype 055:B5. The experimental design was a randomized complete block design in a 2×2 factorial arrangement with nine replicates per treatment and, one animal per experimental unit. The data were analyzed in accordance with the multivariate analysis procedure of SAS and, the treatment means of parametric and non-parametric data were compared by Bonferroni's test (P<0.05) and, by Dunn's test (P<0.05), respectively. The data of the blood profiles of alanine aminotransferase, alkaline phosphatase and, creatinine showed that LPS did not cause kidney or liver damage in the animals. The addition of beta-glucan in the diets did not prove the robustness of its effect and biological relevance when provided with low nutrient-density. However, its addition combined with the high-nutrient-density diets showed less marked hypoglobulinemia in piglets, which may have contributed to the decreasing of the synthesis of inflammatory mediators.

In vitro study of cyclosporine A 0.05 % on primary and recurrent pterygium fibroblasts

To compare the cyclosporine 0.05 % exposure effect on fibroblasts from primary and recurrent pterygium. Primary culture of fibroblasts from primary and recurrent pterygium was performed until the third passage, which was exposed to cyclosporine 0.05 % in a group and the other remaining unexposed (control group), in triplicates. After 3, 6, 12, and 17 days of exposure the viable cell counting was performed by hemocytometer. The results were statistically analyzed using the technique of analysis of non-parametric variance model for repeated measures with three factors. There was a significant reduction in both fibroblast proliferation, in primary as in the recurrent pterygium cultures exposed to cyclosporine when compared not exposed cultures, with statistical significance (P < 0.05). Comparing primary and recurrent pterygium that received the drug, there was no significant difference in cell proliferation in relation to primary or recurrent pterygium. Cyclosporine 0.05 % is effective in inhibiting fibroblast proliferation in culture, both in primary and as in recurrent pterygium.

Molhabilidade de material reembasador: efeito dos agentes químicos de limpeza

Risk of mechanical injuries contraindicate brushing and elect chemical agents as appropriate for daily cleaning of dentures relined with resilient materials. It was evaluated the effect of denture cleansers on the wettability of denture relining material (Dentusoft, Dental Medrano). We used 20 discs of acrylic resin thermoactivated VipiCril ® with 30mm diameter and 4mm thick, covered by 2mm Dentusoft ®. Divided into 4grupos were stored in artificial saliva at 37 +1 º C for 30 days, immersed daily for 15minutes in distilled water (GI), Corega ® Tabs (GII), a solution of sodium bicarbonate (GIII) or solution of sodium hypochlorite (GIV) after which, on the soft liner were poured 2 ml of type IV gypsum (Durone IV, Dentsply). Reached the final setting of the gypsum specimens were sectioned vertically and medially, settled water with sandpaper No. 400 and mounted on suitable device for reading (in the right and left) of the contact angle Carl Zeiss microscope (precision, 001). The results were submitted to analysis, showed non-normal distribution, opting for non-parametric test. Kruskal Wallis test performed at 5% significance, there was statistical difference between the groups with lower average contact angle for GII. It was concluded that the chemical cleaning Corega Tabs ® allowed a better adaptation of relining the gypsum studied.

Efeitos do treinamento misto na promoção da saúde e sua interferência no perfil lipidêmico em indivíduos diabéticos tipo 2

Diabetes is a chronic disease that currently affects 171 million individuals approximately worldwide, with projection to reach 366 million people in 2030, increasing the prevalence of 2.8% in 2000 to 4.4%. The dyslipidemia is certainly one of the associated metabolic alterations most important, if we consider the main cause of death in Diabetes - the cardiovascular disease (CVD). One of the prevention and help factors in the Diabetes treatment and in the fall of associated complications is the physical exercise, which contributes to a better life quality to the diabetic. The main objective of the work was to evaluate the effect of a mixed physical exercises training program (aerobic/anaerobic with pause-active), including walking exercises, weightlifting and swiss ball, about possible changes in the blood lipid profile of adult individuals type 2 diabetics. The methodology used an experimental model of pre-test and post-test applied to the group. The data were first analyzed in a descriptive way for the normalization and the elaboration of averages and sample diversions. The sample was subdivided in two moments, being one pre and other post then weeks of training. After these procedures, the results of the values of the lipidic profile and glycemia were compared between the pairs pre and post training (test T Student, pair data), non-parametric. With the study, we can conclude that in despite of the low uptake of participants in the search, for reasons already cited, and the great age difference between them, the found results were partially satisfactory, because we achieved significant changes only in the glycemic variables, but we suggest future studies in the molds here proposed.

Influência do tempo sedentário na qualidade de vida e na percepção dos estados de ânimo em idosos fisicamente ativos

Introduction: Sedentary behavior is characterized by individuals who designed much of the day sitting or lying down activities, even if such conduct regular physical activity. Over the years people tend to be less active, worsening the quality of life. For healthy aging is necessary for the individual to be constantly active, and moving activities improve mood and quality of life, though little is known of the influence of sedentary behavior in these variables. Aim: To investigate the association between sedentary time, quality of life and mood states of elderly women engaged in physical activity. Methodology: The study included 68 elderly women who belong to the Physical Activity Program for the Elderly (PROFIT), for at least 6 months. These answered the Sedentary Behaviour Questionnaire, the Pentacle Welfare and IPAQ Short Version. The Pep States List Reduced and Illustrated (LEA-RI) was applied before and after a workout and before and after three times of sedentary behaviors. To evaluate the difference of sedentary behavior time average for each domain of quality of life was conducted the analysis of the 95% confidence interval for the STATA program version 12.0 and to the moods list data a non-parametric test - test binomial using SPSS version 17.0 program and has adopted a p≤0,05. Results: A moderate intensity physical activity was the most practiced (939.5 ± 650.2 min / week) and the activity most frequently performed in sedentary time was watching television (187.6 ± 96,4min / day). In general, the quality of life for the elderly is considered good (98.39%) and the disease is most prevalent hypertension (29.47%). After a physical activity older felt less useless, less shy and less fear and after a sedentary behavior, felt less agitated and less useless. In relation between the domains of QOL and sedentary behavior time, there were no statistical differences. Conclusion: Elderly active even after a sedentary behavior...
