Abstract: during the maturation and harvest of soybean (glycine max (l.) merr.) seed the ideal climatic conditions include dryness and lower temperatures. using winter-sown (july to september) soybean we verified the effects of irrigation on the physiological quality of soybean seeds during maturity using a factorial treatment design with three varieties (iac-19, conquista and iac 8-2) and two irrigation interruption times (starting at stage r7 and irrigating until 14 days after stage r8). the samples were taken at stage r7 and at 3 days, 7 days, 10 days, 14 days (stage r8) and 28 days after starting stage r7. we evaluated the percentage germination, vigor using accelerated aging and electric conductivity tests, and the percentage of spotted and imperfect seeds and found that irrigation after stage r7 does not reduce seed quality but can improve the physiological potential of the seeds.

Abstract: background and objectives: the administration of powerful and short duration anesthetic agents is essential for patients undergoing bariatric surgical procedure. the dexmedetomidine, an a 2-adrenergic agonist, has appeared as an adjuvant option of the venous anesthesia technique. this study aimed at assessing the efficacy of dexmedetomidine associated with the venous anesthesia in morbid obese patients undergoing gastroplasty procedures. methods: retrospective analysis of morbid obese patients undergone open bariatric surgical intervention under anesthesia with propofol and alfentanil, with or without dexmedetomidine. patients were allocated into two groups: control (propofol and alfentanil) and dexmedetomidine (propofol, alfentanil and dexmedetomidine). for both groups, the anesthetic maintenance was as follows: propofol = 0.075 to 0.1 mg.kg-1.min-1 and alfentanil = 0.75 to 1 μg.kg-1.min-1; in the dexmedetomidine (dmd) group, initial dose of 1 μg.kg-1 in 10 min and maintenance with 0.4 to 0.7 μg.kg-1.h-1. the variables studied were: age, gender, body mass index (bmi), surgical time and recovery time, heart rate (hr), systolic and diastolic blood pressure (sbp and dbp), hemoglobin peripheral saturation (spo-2), propofol and alfentanil consumption and side effects. results: the dexmedetomidine group has shown a significant reduction in propofol and alfentanil consumption. the heart rate presented a significant variation only in the dexmedetomidine group. both spb and dbp presented a statistically significant reduction in both groups for the first 20 minutes, and subsequent stabilization. no side effects were observed in both groups of patients. conclusions: this study has shown the efficacy of dexmedetomidine administration in combination with venous anesthesia with propofol and alfentanil, thus promoting reduction in venous anesthetic drugs consumption, cardiovascular stability and time to recovery similar to that of the technique without dexmedetomidine. no side ef

Abstract: background and objectives: different oxygenation techniques aim at promoting denitrogenation before apnea during induction. the main reason why cio2 = 100% cannot be reached is the lack of adequate face mask coupling, allowing the entry of room air. although anesthesiologists know this principle, not all of them apply it correctly, facilitating the entry of air in fresh gases flow and consequently diluting cio2. this prospective study was performed to comparatively evaluate, through the variation of oxygen expired concentration (ceo2), the efficacy of the oxygenation technique via face mask in the conditions routinely used by anesthesiologists, simulating situations of progressive leaks. methods: oxygen end-tidal concentrations of 15 volunteers, physical status asa i, were studied with 8 deep breaths (vital capacity) in 60 s with fresh gas flow of 10 l.min-1. the face mask was: tightly fitted with 100% cio2 (tf100) or varying from 50% to 90%, (tf50, tf60, tf70, tf80, tf90); gravity-coupled to face and 100% cio2 (grav) and moved 1 cm away from face with 100% cio2 (aw). ceo2 was recorded at 10 s intervals. p < 0.05 was considered statistically significant. results: ceo2 has increased for all groups (p < 0.001), but only tf100 reached values close to ideal (82.20 - 87). comparing mean ceo2 of grav and tf100 at the end of 60s, (82.20 and 65.87) there was a difference of approximately 20% between both techniques, since gravity-coupled mask only did not provide adequate oxygenation. there were no significant differences between groups tf70 and grav (65.87 and 62.67) in all studied moments, suggesting that the latter simulates a 70% cio2 at 60 s. mean aw group ceo2 increased to 47.20 at 60s showing that this technique may be associated to unacceptable risk of hypoxemia. conclusions: all situations of face mask coupling gradually increased ceo2, although with decreased oxygenation efficacy due to situations of face mask malposition. this study has shown the need for attenti
