Abstract Objective The aim of this study was to perform a histomorphometric evaluation of the repair process in rat teeth replanted after root canals were filled with calcium hydroxide (CH) and mineral trioxide aggregate (MTA). Design Upper right incisors were extracted from 30 rats divided into three groups (n = 10). The teeth were stored dry for 60 min, after which the pulp and periodontal ligament (PDL) were removed and immersed in acidulated-phosphate sodium fluoride solution. In Group I, the root canals were filled with saline; in Group II, they were filled with CH; and in Group III, they were filled with CH, and the foramen was sealed with an MTA plug. The teeth were replanted, and the animals were sacrificed after 60 days. The sections with teeth were removed for histological preparation (haematoxylin and eosin, H&E). The characteristics of the PDL, cementum, dentine, and alveolar bone, as well as the occurrence of inflammatory and replacement root resorption and apical sealing, were subjected to histological and morphometric analysis (P < 0.05). Results Group I was the most affected by root resorption (mean = 67.05%). In Groups II and III, the resorption averaged 42.2% and 11.7%, respectively. Group III was less affected by inflammatory resorption and presented more areas of apical sealing by mineralized tissue (P < 0.05). Conclusion An apical MTA plug improved the repair of the replanted tooth by decreasing surface resorption and repairing mineralized tissue in the periapical region. © 2015 Elsevier Ltd. Source

Glyphosate is the main herbicide used worldwide and is recommended for the control of weeds in various crops. In spraying with winds of 2 m s-1, glyphosate drift can reach up to 160 m beyond the target site, which is considered as harmful to the neighboring crops. The objective of this study was to evaluate the dry matter and nutrient content of common bean (Phaseolus vulgaris L.) cv. Pérola subjected to glyphosate drift. The experiment was conducted in a greenhouse at the State University of North Fluminense Darcy Ribeiro - UENF, Campos dos Goytacazes - RJ using the common bean (Phaseolus vulgaris L.) cv. Pérola, on a Quartzipsamment and a Paleudalf Tb . The experiment was arranged in a randomized block design in a 4 x 2 factorial scheme with four replications, with the first factor comprising the subdoses of 0 , 14.4, 43.2 and 86.4 g ha-1 acid equivalent (e.a) of glyphosate in the form of ammonium salt applied 25 days after sowing (V4 stage) and the second factor consisting of the two soils. Glyphosate drift reduced dry mass of branches and shoots at 20 days after application (DAA), the content of nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg) and sulfur (S) at 10 DAA and N, P, Ca and Mg at 20 DAA of common bean cv.

Background: There is a lack of questionnaires in Brazilian Portuguese to evaluate patient-reported lower limb function. Objective: To translate, cross-culturally adapt to the Brazilian population, and evaluate the psychometric properties of the Lower Extremity Functional Scale (LEFS). Method: The LEFS was translated by two independent assessors and back-translated to English. Then, the LEFS-Brazil was tested on 20 patients who answered the questionnaire in the cross-cultural adaptation phase. For the evaluation of the psychometric properties, 100 patients answered the questionnaire. The reliability was tested by two independent assessors. The Medical Outcomes Study 36-item from Health Survey (SF-36) was used as the criterion method for construct validity. The sensitivity to change was tested for four consecutive weeks. Results: The internal consistency was α=0.96. The intra-observer reliability was CCI (intraclass correlation coefficient)=0.96 and CCI interobserver=0.98; the Bland and Altman mean difference (d) intra-observer=-1.52 and d interobserver=0.46. The correlation between the LEFS and SF-36 in the first week was the following: physical function r=0.82, physical role r=0.57, emotional role r=0.43 and mental health r=0.33. The LEFS was responsive when comparing the mean of the first week to the second, third and fourth weeks and comparing the second to the fourth week. The cut-off point was 11, and the area under the receiving operator curve was 0.96 95% CI [0.88;0.99], with sensitivity=0.96, 1-specificity=0 and standard error=0.02. Conclusion: The LEFS-Brazil is reliable, valid and responsive. Source

Flexibility is a key component of physical fitness. It has been suggested that measures of physical fitness components may vary throughout the day. The aim of this study was to analyse the effects of the time of day on flexibility performance. 26 men (mean age=25.4 years, SD=2.5) were evaluated by hip flexion on kinematic analysis and also by an absolute score in the modified Sit-and-Reach test during a repeated measure design. This was done during 3 experimental sessions, which took place at 8:00a.m., 1:00p.m. and 6:00p.m., in random order. All subjects were previously familiarized with the test parameters. There was a diurnal variation only in the modified Sit-and-Reach test score between 8:00 a.m and 6:00p.m. (P=0.01). There was no significant difference in the hip kinematic analysis between hours. These findings suggest that flexibility performance in the modified Sit-and-Reach test, in absolute scores, is affected by the time of day, with higher performance in the evening. © 2011 Georg Thieme Verlag KG Stuttgart.

NBPT (N-(n-butyl) thiophosphoric triamide), a urease inhibitor, has been reported as one of the most promising compounds to maximize urea nitrogen use in agricultural systems. The objective of this study was to evaluate the performance of irrigated wheat fertilized with urea or urea + NBPT as single or split application. The experiment was conducted from June to October 2006 in Viçosa, MG, Brazil. The experimental design followed a 2×2 factorial scheme, in which urea or urea + NBPT were combined with two modes of application: full dose at sowing (60kg ha-1) or split (20kg ha-1 at sowing + 40kg ha-1 as topdressing at tillering), in randomized blocks with ten replications. The split application of nitrogen fertilization does not improve the yield wheat under used conditions. The use of urease inhibitor improves the grain yield of wheat crop when urea is applied in topdressing at tillering, but its use does not promote difference when urea is applied in the furrow at planting.
