A novel and rapid voltammetric assay for the simultaneous determination of monolinuron (MLN) and linuron (LIN) using an electrochemically pretreated pencil graphite electrode (PGE*) is reported for the first time. Enhanced oxidation peak currents of MLN and LIN were observed at PGE* when compared with electrochemically non-pretreated PGE. Differential pulse voltammetric (DPV) results showed distinct anodic peaks at 1.064 V and 1.170 V for MLN and LIN, respectively. Under optimum conditions, the detection limits were 3.7 x 10(-7) mol L-1 and 5.8 x 10(-7) mol L-1 for MLN and LIN respectively. The DPV method was applied for the quantitative determination of the mentioned compounds in spiked tap water samples enriched by solid phase extraction. The voltammetric results were in good agreement with high-performance liquid chromatography data.

Study Objective: To investigate whether the rate of increase in the performance of abdominal myomectomy over a laparoscopic approach after the US Food and Drug Administration (FDA) safety communication regarding morcellator use for myomectomy differs among races. Design: Retrospective cohort study. Setting: The American College of Surgeons National Surgical Quality Improvement data. Patients: Patients aged 18 to 55 years who underwent either laparoscopic or abdominal myomectomy, excluding malignant cases, emergency cases, operations performed by nongynecologic specialists, and cases in which myomectomy was performed during cesarean section. Interventions: None. Measurements and Main Results: The odds ratios of abdominal myomectomy over laparoscopic myomectomy before and after the release of the FDA communication were calculated in 3 race categories: white, African American, and other races. In a logistic regression analysis adjusted for possible confounders, including all races, the odds ratio of abdominal myomectomy before and after the FDA communication was 1.30 (95% confidence interval [CI], 1.20-1.41; p <. 001). In a logistic regression analysis with a product term of FDA communication exposure and race as a possible effect modifier, the African American population showed a significantly greater change in the odds of abdominal myomectomy over laparoscopic myomectomy in comparison with the white population (1.22; 95% CI, 1.02-1.47; p =.03). In contrast, other races showed no significant change (.83; 95% CI,.64-1.08; p =.17). Conclusion: After the FDA communication, the odds ratio of abdominal myomectomy was disproportionately increased in the African American population.

This study reports an innovative pathway for successfully synthesizing composite panels using various waste input. For this purpose, seven types of powder from waste or widely available filler i.e. Quartz off-cut, sand, waste seashell, dolomite, limestone aggregates, concrete waste and limestone dust were used. The study aims to assess the effectiveness and mechanical properties of the various waste powder in the production of powder-resin composites. The panels were then compared with the novel polymeric glass composite (PGC) in the previous study (Heriyanto et al., 2018). Following the same procedure in PGC, the filler was individually grounded to 64-108 mu m and chemically treated with amino silane coupling agent (CA). The powder filler (untreated or treated) is then mixed with the resin binder with a ratio of 80/20 respectively, followed by hot pressing the mixture at the pressure of 550 bar at 65 degrees C for 1 h. The final composite slab is then further cut for mechanical testing. It was found in the study that when CA was not added, surface roughness of the powder particles affected the flexural strength of the final panel significantly. High surface roughness particles such as in Quartz, sand and seashell adhere effectively with the resin binder which led to higher strength. On the contrary, other factors like smooth particle morphology in glass, dolomite and limestone as well as porous structure in concrete and clump of very fine powder in limestone dust degrade the strength of the final panels. With CA addition, adhesion between resin and powder filler were improved significantly. Flexural strength after the CA treatment was found to be much affected by particle characteristics. Silica-based panels i.e. quartz, sand and glass which consist of high strength and hardness of silica particles perform better compared to that of calcium carbonate-based panels. Compression strength, toughness, stiffness, scratch resistance, density and water absorption were also reported in this study. The properties of all the treated panels are found to be comparable, or if not, much better than natural stones. These new approaches of using waste filler in powder – resin based composites can be a new alternative to produce green materials that deliver economic and environmental benefits.

Solid-contact ion-selective electrodes (SC-ISEs) have shown great potential for routine and portable ion detection. The introduction of nanomaterials as ion-to-electron transducers and the adoption of different performance-enhancement strategies have significantly promoted the development of SC-ISEs. Herein, new solid-contact ion-selective electrodes, along with the implementation of multiwalled carbon nanotubes (MWCNTs) as ion-to-electron transducers and potassium tetrakis (p-chlorophenyl) borate (KTpClB) as lipophilic ionic additives, were presented for the detection of isoproturon (IPU) and diuron (DU) herbicides. Molecularly imprinted polymers (MIPs), with special molecule recognition properties for isoproturon (IPU) and diuron (DU), were prepared, characterized, and introduced as sensory recognition materials in the presented electrodes. Sensors revealed a near-Nernstian response for both isoproturon (IPU) and diuron (DU) with slopes of 53.1 +/- 1.2 (r(2) = 0.997) and 57.2 +/- 0.3 (r(2) = 0.998) over the linear ranges of 2.2 x 10(-6)-1.0 x 10(-3) M and 3.2 x 10(-6)-1.0 x 10(-3) M with detection limits of 8.3 x 10(-7) and 1.4 x 10(-6) M, respectively. The response time of the presented sensors was found to be <5 s and the lifetime was at least eight weeks. The sensors exhibited good selectivity towards isoproturon (IPU) and diuron (DU) in comparison with some other herbicides, alkali, alkaline earth, and heavy metal ions. The presented sensors were successfully applied for the direct determination of isoproturon (IPU) and diuron (DU) in real water samples. Recommanded Product: 64-10-8.

OBJECTIVE In patients with type 2 diabetes uncontrolled with metformin, exenatide once weekly (QW) plus dapagliflozin produced greater reductions in glycemic parameters (glycated hemoglobin [HbA(1c)], fasting plasma glucose [FPG], and 2-h postprandial glucose [2-h PPG]), weight, and systolic blood pressure (SBP) than exenatide QW or dapagliflozin alone after 28 weeks of treatment in DURATION-8. Following a 24-week extension period, improvements were sustained at 52 weeks. In this study, we investigated efficacy and safety at 104 weeks after randomization. RESEARCH DESIGN AND METHODS DURATION-8 was a 104-week, multicenter, double-blind, randomized, active-controlled, phase 3 trial. In total, 695 adults (aged >= 18 years) with type 2 diabetes and inadequate glycemic control (HbA(1c)8.0-12.0% [64-108 mmol/mol]) despite stable metformin monotherapy (>= 1,500 mg/day) were randomly assigned (1:1:1) to receive exenatide 2 mg QW plus once-daily dapagliflozin 10 mg, exenatide QW plus placebo, or dapagliflozin plus placebo. All 104-week evaluations were exploratory. RESULTS At week 104, 431 (62.0%) patients completed treatment. The adjusted least squares mean change (SE) from baseline to week 104 in HbA(1c)was greater with exenatide QW plus dapagliflozin (-1.70% [0.11]) versus exenatide QW plus placebo (-1.29% [0.12];P= 0.007) and dapagliflozin plus placebo (-1.06% [0.12];P< 0.001). Clinically relevant changes in FPG, 2-h PPG, weight, and SBP were also observed with exenatide QW plus dapagliflozin. There were no unexpected safety findings, and exenatide QW plus dapagliflozin was well tolerated, with no episodes of major hypoglycemia. CONCLUSIONS In this exploratory analysis, among those individuals who completed the trial without rescue therapy, there was clinically relevant efficacy over 2 years with exenatide QW plus dapagliflozin, with no unexpected safety findings.

Objectives: Brain metastases are common among patients with non-squamous non-small-cell lung cancer (NSCLC) and result in a poor prognosis. Consequently, such patients are often excluded from clinical trials. In Italy an expanded access program (EAP) was used to evaluate nivolumab efficacy and safety in this sub population outside a clinical trial. Materials and methods: In this EAP, nivolumab was available for patients with non-squamous NSCLC in progression after at least one systemic treatment for stage IIIB/IV disease. Nivolumab 3 mg/kg was administered intravenously every 2 weeks. Patients with brain metastases could be included if they were asymptomatic, neurologically stable and either off corticosteroids or on a stable or decreasing dose of <= 10 mg/day prednisone. Results: 409 out of 1588 patients included had asymptomatic or controlled brain metastases. A median of 7 doses (range 1-45) were delivered. Median follow-up was 6.1 months (range 0.1-21.9). The disease control rate was 39%: 4 patients had a complete response, 64 a partial response and 96 showed stable disease. At baseline, 118 patients were on corticosteroids and 74 were undergoing concomitant radiotherapy. The median overall survival in this subpopulation was 8.6 months (95% CI: 6.4-10.8). 337 discontinued treatment for various reasons, 23 (7%) of whom due to adverse events, in line with that observed in the overall population and in previous studies. Conclusions: Our results confirm that nivolumab is active in non-squamous NSCLC patients with brain metastases, despite their poor prognosis. Its safety profile is also concordant with results in the EAP overall population and in patients with other malignancies. SDS of cas: 64-10-8.

Most of the known methods for the synthesis of heterocyclic compounds have disadvantages, such as a long reaction time and aggressive conditions. We have developed a new, rather simple and efficient method for the synthesis of a number of glycoluryls and hydantoins in water using a etidronic acid (HEDP) as Green catalyst. So, for the first time, the condensation reaction of ureas with 1, 2-dicarbonyl compounds was carried out in the presence of HEDP. Also based on NMR studies, a chemism of these reactions, which is stepwise, is proposed. It has been established that the optimal conditions for the synthesis of glycoluryls and hydantoins using HEDP are: temperature 80 degrees C-90 degrees C, 40-20 minutes, and the ratio of urea and HEDP is 1:1. In all cases, the remaining aqueous filtrate containing HEDP after the reaction can be reused for other cycles synthesis of glycoluril and other compounds, because HEDP is not converted during the reaction.

Four polar stationary phases (ethylene-bridged hybrid silica, cyanopropyl, 2-ethylpyridine, and zwitterionic sulfobetaine) have been characterized in supercritical fluid chromatography (SFC) by linear free energy relationships (LFER) method with an extended set of Abraham’s descriptors. Temperature (25-55 degrees C) and pressure (110-180 bar) effects on analyte retention, separation selectivity and LFER-coefficients of chromatographic systems have been studied using the 89 test compounds of various chemical classes and carbon dioxide – methanol (9:1 v/v) binary solvent as a mobile phase. It was found that for the selected stationary phases temperature and pressure had only moderate effects on selectivity. The retention times of all analytes decrease, as can be expected, if the pressure rises at the isothermal conditions due to the increase of the fluid density and its eluting power. The effect of temperature on retention is complicated and depends both on the chemical class of analyzed compounds and the stationary phase type. Temperature and pressure variations lead to small changes in the LFER-coefficients, and general trends observed do not depend much on the stationary phase type. It may be difficult to interpret the LFER-analysis results because of the evident, more significant chromatographic phenomena. (C) 2019 Elsevier B.V. All rights reserved.
