g., hypotension; these were evident during clonidine infusion. Epidurally, the antinociceptive potency of fadolmidine was weaker (ED50 128 μg) than when intrathecally administered and weaker than that of epidural clonidine (ED50 51 μg). At analgesic doses, fadolmidine injection induced moderate initial hypertension concomitantly with a decrease in heart rate whereas clonidine evoked hypotension and bradycardia. These results suggest that especially when non-opioid long-term pain relief is needed, an intrathecal infusion of fadolmidine can provide long-term antinociception with less of the known use-limiting adverse effects associated with clonidine.INTRODUCTION Esophagectomy for oncological reasons is associated with high morbidity, which was intended to be reduced by a minimally invasive approach. Main problem of the minimally invasive approach is the challenge of a safe intrathoracic anastomosis. To address this problem several methods such as a collar anastomosis instead of an intrathoracic anastomosis with poor functional outcome, hybrid techniques with an open approach to the demanding intrathoracic circular stapled anastomosis ore robotic assistance have been used. We demonstrate the minimally invasive linear stapler technique for the intrathoracic esophagogastrostomy, which can be applied quite easily even without robotic assistance. SURGICAL TECHNIQUE The abdominal part is performed with the patient in French position. After division of the greater omentum along the gastroepiploic arcade and the spleen as well as the perigastric incision of the lesser omentum 6cm from the pylorus a 4,5 cm gastric conduit is created in linear stapler technique. Next an intraabdominal and transhiatal systematic lymphadenectomy is performed. For the thoracic part the patient is repositioned in a left side position. The thoracic lymphadenectomy is completed, and the specimen removed via mini-thoracotomy. For the anastomosis the esophageal stump is incised, and the gastric conduit is opened 5 cm from the oral resection line. Once the stapler is fired and removed the remaining opening is hand-sewn in a modified double-layer technique. RGFP966 purchase DISCUSSION The side-to-side esophagogastrostomy in linear stapler technique seems to be a quite easily feasible and safe alternative for the reconstruction after minimally invasive esophagectomy. To confirm this, the method is currently investigated in a randomized controlled trial.Hypernatremia is a common electrolyte disorder in daily clinical practice. In many cases hypernatremia is caused by a lack of free water or an increased salt load. Out-of-hospital acquired hypernatremia is often caused by an increased loss of water or a decreased water intake. By contrast, hospital-acquired, nosocomial hypernatremia is often induced by an inadequate fluid balance with saline infusions, saline overload, or due to osmotic diuresis. The consequences are structural changes in the cell morphology such as cell shrinkage. Chronic hypernatremia affects all cell functions predominantly with cerebral symptoms and coma; the main complication is a too-rapid compensation of an adapted electrolyte imbalance with development of cerebral edema. The overall osmolality should always be considered. Overall changes in osmolality correspond to the effect on the cellular stress situation and have to be taken into account and balanced slowly. In cases of unknown duration, a chronic disorder should be assumed.This study aimed to model the inactivation of Lactobacillus brevis DSM 6235 while retaining the viability of yeasts during washing brewer's yeast with phosphoric acid and chlorine dioxide. The independent variables in the acid washing were pH (1-3) and temperature (1-9 °C), whereas in the washing with chlorine dioxide, concentration (10-90 mg/L) and temperature (5-25 °C) were assessed. The predictive models obtained for the four response variables γLA, γCl (decimal reduction of L. brevis DSM 6235), Vf/V0LA, and Vf/V0Cl (brewer's yeast viability ratio) were found to have R2 > 0.80 and values of Fcalc > Freference. Then, the models were considered predictive and statistically significant (p  less then  0.10). Our results indicated that phosphoric acid and chlorine dioxide washing resulted in up to 7 and 6.4 (log CFU/mL) decimal reductions of L. brevis DSM 6235, respectively. On the other hand, the viability of the brewer's yeast ranged from 22.3 to 99.4%. L. brevis DSM 6235 inactivation was significantly influenced by parameters pH(Q) and T°C(Q) when phosphoric acid was applied, and by parameters mg/L(L), mg/L(Q), T°C(Q), and mg/L × T°C when ClO2 was applied. The validation of the models resulted in bias (γLA, 0.93/Vf/V0LA, 0.99 - γCl, 1.0/Vf/V0Cl, 0.99) and accuracy values (γLA, 1.12/Vf/V0LA, 1.01 - γCl, 1.08/Vf/V0Cl, 1.03). The results of this study indicate that it might be possible to decontaminate brewer's yeast through acid and chlorine dioxide washing while keeping its viability. This procedure will result in the reduction of costs and the lower generation of brewer's waste.Geobacter sulfurreducens is capable of reducing Pd(II) to Pd(0) using acetate as electron donor; however, the biochemical and genetic mechanisms involved in this process have not been described. In this work, we carried out transcriptome profiling analysis to identify the genes involved in Pd(II) reduction in this bacterium. Our results showed that 252 genes were upregulated while 141 were downregulated during Pd(II) reduction. Among the upregulated genes, 12 were related to energy metabolism and electron transport, 50 were classified as involved in protein synthesis, 42 were associated to regulatory functions and transcription, and 47 have no homologs with known function. RT-qPCR data confirmed upregulation of genes encoding PilA, the structural protein for electrically conductive pili, as well as c-type cytochromes GSU1062, GSU2513, GSU2808, GSU2934, GSU3107, OmcH, OmcM, PpcA, and PpcD under Pd(II)-reducing conditions. ΔpilA and ΔpilR mutant strains showed 20% and 40% decrease in the Pd(II)-reducing capacity, respectively, as compared to the wild type strain, indicating the central role of pili in this process. RT-qPCR data collected during Pd(II) reduction also confirmed downregulation of omcB, omcC, omcZ, and omcS genes, which have been shown to be involved in the reduction of Fe(III) and electrodes. The present study contributes to elucidate the mechanisms involved in Pd(II) reduction by G. sulfurreducens. Graphical Abstract KEY POINTS • Transcriptome analysis provided evidence on Pd(II) reduction by G. sulfurreducens. • Results indicate that electrically conductive pili is involved in Pd(II) reduction. • G. sulfurreducens was not able to grow under Pd(II)-reducing conditions. • The study contributes to a better understanding of the mechanisms in Pd(II) reduction.
