Efficient and cost-effective method to destroy complex dyes is warranted to combat increasing water pollution. In the present study, homogeneous photocatalytic oxidation (PCO) of Reactive Black 5 (RB5) dye was studied using ferric ions (Fe(III)) under visible light (VL) irradiation and sunlight (SL). In the presence of 5 mM ferric ions and at pH 2.6, more than 80% of initial 20 mg/L RB5 was decolourized in 60 min under artificial VL. Decolourization followed pseudo first-order kinetics with the reaction rate constant 0.0356 min-1. 79% of initial COD was removed at the end of 60 min, suggesting mineralization of RB5 as the main cause of decolourization. Using similar experimental conditions under SL, more than 90% RB5 was decolourized in 15 min with an almost 10-fold increase in the reaction rate constant (0.34 min-1). Rate and extent of RB5 destruction significantly decreased in the presence of •OH scavenger indicating photoreduction of Fe-hydroxo species and generation of •OH as the main mechanism of RB5 degradation. RB5 removal increased from ca. 30% to 84% with the increase in Fe(III) concentration from 0.5 to 5 mM. The corresponding 1st-order rate constants increased linearly from 0.006 to 0.036 min-1. RB5 degradation decreased linearly (R2 = 0.98) from 91.7% to 63.3% with the increase in initial RB5 concentration from 10 to 40 mg/L. Fe(III) induced homogenous PCO appears to be a reliable and low-cost method of advanced oxidation without the need for costly reagent such as H2O2.The COVID-19 economic crisis makes it vitally important that workers who earned defined benefit pensions receive them at retirement. Unfortunately, billions of dollars that could help cushion the financial shock are sitting unclaimed, because the people who they belong to cannot locate the company responsible for paying them. As defined benefit pension plans have been terminated, merged and moved over the years, large numbers of deferred vested participants have not been notified about their benefits. The widespread and growing practice of insurance company pension buy-outs can be especially problematic for participants without notice. Broader use of electronic disclosures for pensions also threatens to make the situation worse. In the wake of COVID-19, policy makers should take steps to ensure that pension benefits are part of the economic recovery.Objective. To assess outcome and safety of 571 hybrid natural orifice transluminal endoscopic surgery (NOTES) cholecystectomies. https://www.selleckchem.com/products/LBH-589.html Methods. We retrospectively analyzed all consecutive NOTES cholecystectomies performed at our center between June 2009 and January 2018. All procedures were performed using a hybrid transvaginal technique, including an umbilical small-size trocar. End points, calculated at discharge, 30 and up to 90 days postoperatively, included intra- and postoperative morbidity assessed by the validated Clavien-Dindo classification and the Comprehensive Complication Index (CCI). Special focus was held on outcome and necessity of pre- and postoperative gynecological examinations. Results. We performed 571 hybrid NOTES cholecystectomies within 9 years. The vast majority were elective, 9.6% were emergency cholecystectomies. 6.7% of patients developed at least one complication until discharge, most of them minor (≤grade II). 30- and 90-day complication rates were 10.7% and 11%, respectively. Mean CCI at discharge and postoperative days 30 and 90 was 1.45 (±6.4), 2.3 (±7.7), and 2.4 (±7.8), respectively. Major complications (≥grade IIIa) occurred in 1.6% of patients, and 4 patients required emergency reoperation. No mortality was observed. In 9.8%, an additional abdominal trocar was placed. All patients underwent routine gynecological examination, whereof only 5 were rejected for transvaginal access preoperatively. In no case transvaginal access was discontinued intraoperatively due to gynecological disease. Conclusion. Hybrid NOTES transvaginal cholecystectomy represents a safe and feasible alternative to standard laparoscopic cholecystectomy. Preoperative gynecological examination is no longer routinely necessary, as intraoperative assessment is adequate.Chitosan adhesive hydrogels have attracted interest because of their unique properties. However, it is still a challenge to use simple and unmodified chitosan to synthesize multifunctional hydrogels with adhesive, self-healing and strain sensing properties. Here, a multifunctional hydrogel of Ca2+-chitosan/polyacrylamide（Ca2+- CS/PAAm）with adhesive self-healing and strain sensing properties was carried out by one-step preparation method. The hydrogel has the ability to adhere to a variety of materials, wherein the adhesion strength to rubber surface is 48.4 kPa. The hydrogel has excellent strain sensing capability on finger bending or cyclic stretching, the sensitivity factor is 0.41 ± 0.015. The cut hydrogel healed completely at room temperature within 4 h, and the healing hydrogel can be stretched to 5 times of its original length. This makes Ca2+-CS/PAAm hydrogel to be great potential in the application of strain sensors, wound dressing and skin adhesives.Background High frequency chest wall oscillation (HFCWO) has long been used for airway clearance for patients with cystic fibrosis. Only limited research has evaluated this therapy in adult patients with non-cystic fibrosis bronchiectasis (NCFB). Methods Data from 2596 patients from a registry of adult bronchiectasis patients using HFCWO therapy was used to evaluate hospitalization patterns before and after initiation of HFCWO therapy, as well as antibiotic use and self-reported metrics of quality of life. Self-reported outcomes were also reviewed by cross-checking with sampled patient charts and found to be consistent. Results The number of patients who had at least one respiratory-related hospitalization decreased from 49.1% (192/391) in the year before to 24.0% (94/391) in the year after starting HFCWO therapy (p-value less then 0.001). At the same time, the number of patients who required three or more hospitalizations dropped from 14.3% (56/391) to 5.6% (22/391). Patients currently taking oral antibiotics for respiratory conditions decreased from 57.
