Objective: Acute kidney injury in major surgery is associated with increased postoperative mortality. This study aimed to evaluate renal function after major urologic surgery and intraoperative dexmedetomidine infusion. Methods: Thirty oncologic patients with normal renal function scheduled for prostatectomy or nephrectomy, anesthetized with combined epidural and general anesthesia, were randomized to receive either intraoperative blind infusion of dexmedetomidine (Dexmedetomidine Group, n = 15, 0.5 μg/kg load dose plus 0.7 μg/kg/h) or 0.9% saline (Control Group, n = 15) until the end of surgery. Intraoperative and cumulative 24-hour diuresis, serum creatinine (SCr), calculated creatinine clearance (ClCr) and serum cystatin C (SCys) at postoperative days 1, 2 and 3 and 2 weeks after surgery were evaluated. Results: Mean ± standard deviation values for intraoperative diuresis in Dexmedetomidine and Control Groups were 566 ± 396 mL and 298 ± 153 mL, respectively (p = 0.014). Cumulative 24-hour diuresis in Dexmedetomidine and Control Groups was 1947 ± 266 mL and 1748 ± 237 mL, respectively (p = 0.91). Mean values of SCr, ClCr and SCys were not

Abstract: six brazilian commercial mangoes were analysed by hrgc-o-aeda-ms, viz., carlota, haden, espada, cora??o de boi, rubi and tommy atkins. all them showed ethyl butanoate as the main aroma character impact compound by aeda evaluation. the ethyl esters of 2 and 3-methylbutanoic acids are also important, the main contribution in carlota variety being 2(s) enantiomer. in rubi variety, both 2(r) enantiomer and 3-methyl isomer contributes to the caprylic fruity note observed. in four varieties, viz., haden, espada, rubi and tommy atkins, d-3-carene showed to be the second impact aroma compound presented. in tommy atkins variety, a-pinene also has a significant contribution, mainly due to its (1r,5r)(+)-enantiomer.
