Genetic Parameters for Growth Traits of Mediterranean Buffaloes from Brazil, Estimated By Bayesian Inference

Quantitative analysis of growth genetic parameters is not available for many breeds of buffaloes making selection and breeding decisions an empirical process that lacks robustness. The objective of this study was to estimate heritability for birth weight (BW), weight at 205 days (W205) and 365 days (W365) of age using Bayesian inference. The Brazilian Program for Genetic Improvement of Buffaloes provided the data. For the traits BW, W205 and W365 of Brazilian Mediterranean buffaloes 5169, 3792 and 3883 observations have been employed for the analysis, respectively. In order to obtain the estimates of variance, univariate analyses were conducted using the Gibbs sampler included in the MTGSAM software. The model for BW, W205 and W365 included additive direct and maternal genetic random effects, random maternal permanent environmental effect and contemporary group that was treated as a fixed effect. The convergence diagnosis was performed employing Geweke, a method that uses an algorithm from the Bayesian Output Analysis package that was implemented using R software environment. The average values for weight traits were 37.6 +/- 4.7 kg for BW, 192.7 +/- 40.3 kg for W205 and 298.6 +/- 67.4 kg for W365. The heritability posterior distributions for direct and maternal effects were symmetric and close to those expected in a normal distribution. Direct heritability estimates obtained using the modes were 0.30 (BW), 0.52 (W205) and 0.54 (W365). The maternal heritability coefficient estimates were 0.31, 0.19 and 0.21 for BW, W205 and W365, respectively. Our data suggests that all growth traits and mainly W205 and W365, have clear potential for yield improvement through direct genetic selection.

Níveis de sobrecarga, ansiedade e depressão de cuidadores de pacientes com doença de Alzheimer participantes e não participantes de grupos de apoio

Currently , as a result of the significant increase in the number of elderly, one can observe an increase in the number of chronic diseases , among them Alzheimer's disease (AD) , which affects both patients and their caregivers , that due care with the patient , just overwhelmed , anxious and depressed. Therefore, this study aims to draw a profile of caregivers of Alzheimer's patients, correlating the physical activity of patients with levels of overload, anxiety, depression caregivers. For both sample consisted of 40 patients with AD to characterize the physical activity levels and perform activities of daily living. In addition, we evaluated 40 caregivers. Patient assessment was made through a medical history, beyond the score Clinical Dementia Rating (CDR), Mini - Mental State Examination (MMSE), Modified Baecke Questionnaire for Older Adults (MBQ) , Functional Activities Questionnaire PFEFFER (QAFP) , and the Self Perception Performance in Activities of Daily Living (EAPAVD). For assessing the caregiver was also used an interview, then the Neuropsychiatric Inventory (NPI), anxiety and depression scale (HAD) Scale and the Zarit caregiver burden (Zarit). The data were processed using descriptive procedures for the analysis of characterization of samples, such as cognitive screening and physical activity level and profile of caregivers. There was a normal distribution of the data using the Shapiro Wilk, For data with normal distribution were used parametric descriptive procedures using One Way ANOVA to compare groups and applying a post hoc Bonferroni. As for the data that showed the destruction not normal was used to standardize the test by Z -score , and then treated by means of parametric statistical procedures , as presented earlier . The Pearson correlation was used to identify possible associations between variables. It was assumed significance level of 5 % (p ≤ 0.05) for all analyzes. Given these results, we conclude that...

Dimensões das furcas de primeiros pré-molares superiores e sua relação com curetas periodontais

The aim of this in vitro study was to comparatively evaluate the mesio and distal furcation entrance measurements of first maxillary premolar. The measurements were compared with different curette blades. A caliper was used by an examinator to acquire the measurements of root trunk (TR); 1 mm (D1) and 2 mm (D2) both below the furcation entrance. For this study Gracey, Mini Gracey, Padua Lima (PL) and Goldman Fox 4 curettes (Millenium) were selected. Measurements of DT - total distance of the active blade length, DI - width of the active blade, DM - width of the medium part of the active blade were obtained for the curettes. The measurements were obtained in both the coronary face and in the lateral face. The data TR, D1 and D2 presented normal distribution and were statistically analyzed by paired t-test. Statistically significant differences were found in the mesial root trunk region (TR) of both premolars. The mean of the measurements was greater than the distal. Mean and standard deviation were obtained, and both Gracey and Mini Gracey showed mean measurements compatible with the closer furcation entrance (D1 - 1 mm). Goldman Fox 4 showed adaptation only in the mesial face, and Padua Lima showed no access to any of the faces. Thereby it is concluded that the access of the furcation is narrow (D1). The mesial face of the root trunk (TR) showed mean measurement greater than distal face. Gracey and Mini Gracey curettes demonstrated to be compatible for both faces, mesial and distal of the first maxillary premolars studied.
