Seed quality is extremely important for the entire production chain, given that good quality seeds contribute to obtaining vigorous and productive plants. For this reason, it is necessary to evaluate the quality of batches through vigor tests to complement the results obtained from the standard germination test. Because snap bean (Phaseolus vulgaris L.) is propagated through seed, this work was undertaken to standardize the methodology of accelerated aging test for snap bean seed compared to the standard germination test to differentiate batches in terms of physiological quality. The study utilized the cvs "Top Seed" and "Feltrin," with 48, 72 or 96 h exposure periods and temperatures ranging from 15 to 40°C. There were four replications of 50 seeds for each condition. During the germination test, the percentage of first germination count and total germination were analyzed, and the vigor was expressed as a percentage during the accelerated aging test. The accelerated aging test for snap bean seed should be conducted at a temperature of 41°C, with an exposure period of 72 h, considering that this methodology allows differentiating seed batches in terms of physiological quality, contributing to decision-making in the seed production chain. The accelerated aging test was more efficient than the standard germination test in differentiating batches of snap bean seed, proving to be a possible alternative to evaluating the physiological quality of batches of snap bean seed.

Objective: To evaluate the effects of the use of respiratory physiotherapy in children admitted with acute viral bronchiolitis (AVB)., Methods: A literature review was done searching the Pubmed, LILACS, PEDro, and Scielo databases. The following key words were used: bronchiolitis, physiotherapy, techniques, physical therapy, and chest physiotherapy. Both controlled and uncontrolled clinical trials, without limits as to date, were selected., Results: Fifteen articles were included and the use of different techniques of respiratory physiotherapy showed positive results in eight studies. Most (11) were controlled clinical trials, and only two had a double-blind design. Of the 14 studies with a control group, in six this group was submitted to nasopharyngeal aspiration. The most widely used techniques were manual vibration and postural drainage (eight studies), and then tapping/percussion (seven studied). The maneuvers considered as current, e.g., prolonged slow expiration, expiratory flow acceleration, and rhinopharyngeal retrograde clearance, were used in four, four, and two studies, respectively., Conclusions: The use of respiratory physiotherapy in children with AVB remains controversial. The heterogeneity of techniques evaluated in the studies limits the interpretation of efficacy, although its use was considered safe. Recent findings indicating a reduction in the length of the hospital stay remain to be confirmed., (Copyright © 2018 Elsevier Masson SAS. All rights reserved.)
