FeWx/Ce0.68Zr0.32O2 (x = 0, 0.35, 0.7, 1.03, 1.38) catalysts with different molar ratios (x) of W/Fe wereprepared for NH3-SCR. The experimental results showed that catalytic performances of catalysts wereobviously improved by adjusting the molar ratio of W/Fe. FeW1.03/Ce0.68Zr0.32O2 catalyst with W/Fe of1.03 displayed the best catalytic performance, it could obtain higher than 95% NOx conversion and nearly100% N2 selectivity in the temperature range of 250–435 8C. The characterization results indicated thatmore active species of Fe3+, chemical adsorbed oxygen species and surface acid sites would togethercontribute to the excellent NH3-SCR performance of FeW1.03/Ce0.68Zr0.32O2 catalyst.
Purpose: OnabotulinumtoxinA is used widely for the treatment of neurogenic detrusor overactivity. We conducted a systematic review and meta-analysis to assess its efficacy and safety for neurogenic detrusor overactivity treatment. Methods: A systematic literature review was performed to identify all published randomized double-blind, placebo-controlled trials of onabotulinumtoxinA for neurogenic detrusor overactivity treatment. MEDLINE, Embase, and the CENTRAL were employed. Reference lists of retrieved studies were reviewed carefully. Results: Six publications involving 871 patients, which compared onabotulinumtoxinA with a placebo were analyzed. Efficacy of onabotulinumtoxinA treatment was shown as a reduction of the mean number of urinary incontinence episodes per day (mean difference, -1.41; 95% confidence interval [CI], -1.70 to -1.12; P<0.00001), maximum cystometric capacity (135.48; 95% CI, 118.22–152.75; P<0.00001), and maximum detrusor pressure (-32.98; 95% CI, -37.33 to -28.62; P<0.00001). Assessment of adverse events revealed that complications due to onabotulinumtoxinA injection were localized primarily to the urinary tract. Conclusions: This meta-analysis suggests that onabotulinumtoxinA is an effective treatment for neurogenic detrusor overactivity with localized advent events
The changes in antioxidant capacity and phenolics of persimmon during alcoholic fermentation, acetification, and short aging were investigated. An increase in the antioxidant activity was observed when persimmon was transformed from puree to vinegar. The total content of phenolics remained stable, in contrast to the concentration of condensed tannin, which significantly (p\0.05) increased during alcoholic and acetic fermentations, although followed by a decrease after aging. The phenolic compounds were characterized and quantitated. Gallic acid was the main phenolic compound, and its content increased by 14.4% during alcoholic fermentation and reduced by 53.5% during acetic fermentation. Additionally, the flavan- 3-ol compounds increased during alcoholic fermentation and acetification. Vanillyl alcohol, (-)-epigallocatechin, and p-coumaric acid were not observed in persimmon puree but detected in persimmon wine and vinegar. These results indicate that alcoholic and acetic fermentation can improve the antioxidant capacity of persimmon fruit.
Purpose: Penile erection requires integrative interactions between vascular endothelial cells, pericytes, smooth muscle cells, and autonomic nerves. Furthermore, the importance of the role played by pericytes in the pathogenesis of angiopathy has only recently been appreciated. However, global gene expression in pericytes in diabetes mellitus-induced erectile dysfunction (DMED) remains unclear. We aimed to identify potential target genes related to DMED in mouse cavernous pericytes (MCPs). Materials and Methods: Mouse cavernous tissue was allowed to settle under gravity in collagen I-coated dishes, and sprouted cells were subcultivated for experiments. To imitate diabetic conditions, MCPs were treated with normal-glucose (NG, 5 mM) or high-glucose (HG, 30 mM) media for 3 days. Microarray technology was used to evaluate gene expression profiles, and RT-PCR was used to validate sequencing data. Histological examinations and Western blot were used to validate final selected target genes related to DMED. Results: Decreased tube formation and increased apoptosis were detected in MCPs exposed to the HG condition. As shown by microarray analysis, the gene expression profiles of MCPs exposed to the NG or HG condition differed. A total of 2,523 genes with significantly altered expression were classified into 15 major gene categories. After further screening based on gene expression and RT-PCR and histologic results, we found that Hebp1 gene expression was significantly diminished under the HG condition and in DM mice. Conclusions: This gene profiling study provides new potential targets responsible for diabetes in MCPs. Validation studies suggest that Hebp1 may be a suitable biomarker for DMED.
Purpose: We performed a meta-analysis to evaluate the efficacy and safety of mirabegron add-on therapy to solifenacin for patients with overactive bladder (OAB). Methods: We conducted a systematic literature review to identify all randomized, double-blind, controlled trials (RCTs) of this combination (mirabegron and solifenacin) for OAB. Embase, MEDLINE, and the Cochrane Central Register of Controlled Trials were searched. A manual search was also performed to investigate relevant references from the retrieved studies. Results: Four publications describing 5 RCTs that compared combination therapy with solifenacin, including a total of 3,309 patients, were analyzed. The mean number of micturitions per 24 hours (mean difference [MD], -0.45; 95% confidence interval [CI], -0.65 to -0.26; P<0.00001), number of episodes of incontinence per 24 hours (MD, -0.71; 95% CI, -0.14 to -0.02; P=0.04), volume voided per micturition, and number of urgency episodes per 24 hours demonstrated that combination therapy was more effective than solifenacin therapy alone. Safety assessments, including common treatment-emergent adverse events (odds ratio, 1.09; 95% CI, 0.95–1.27; P=0.23) and discontinuations due to adverse events (P=0.30), demonstrated that the combination therapy was well tolerated. Conclusions: This meta-analysis suggests that mirabegron therapy as an add-on to solifenacin provides a satisfactory therapeutic effect for OAB symptoms with a low occurrence of side effects.
Purpose: The aim of this meta-analysis was to evaluate the efficacy and safety of imidafenacin for overactive bladder (OAB) induced by benign prostatic hyperplasia (BPH) in men receiving alpha-blocker monotherapy.Methods: We performed a systematic research of the PubMed, Embase, and Cochrane Library databases, and searched for studies about alpha-blocker with or without imidafenacin treatment for OAB in patients with BPH. We also investigated the original references of the included texts.Results: Four randomized controlled trials including 779 participants with BPH (389 in the alpha-blocker+imidafenacin group and 390 in the alpha-blocker only group) were studied. The main efficacy endpoint was the Overactive Bladder Symptom Score, which showed a mean difference of -1.88 (95% confidence interval, -2.32 to -1.44; P<0.00001), suggesting that alpha-blocker and imidafenacin treatment was effective in treating men with OAB. As other primary efficacy end points, the International Prostate Symptom Score (IPSS) total score (P=0.47), the IPSS storage symptom score (P=0.07), the IPSS voiding symptom score (P=0.60), and the IPSS quality of life score (P=0.18) indicated that 2 methods had no significant differences in treating men with OAB. In terms of safety, which was assessed using postvoid residual volume (P=0.05) and maximum flow rate (P=0.53), the analysis suggested that combination treatment was very well tolerated.Conclusions: This study suggested that imidafenacin plus alpha-blocker was an efficacious and safe treatment for OAB symptoms in BPH patients.
Sedimentation is a major issue in juice production. This paper aims to study the mechanisms of precipitateformation during the storage of cloudy litchi juice. Thesediment concentration, relative turbidity, and f potentialwere analyzed. The supernatant and sediment were separatedto determine the contents of proteins and phenolics. The results showed that the amount of sediment increasedduring the storage. In addition, the total protein and totalphenolic content in the supernatant decreased, whereas theglutelin and total phenolic contents in the sedimentincreased significantly (p\0.05). Moreover, our resultsshowed that the amounts of procyanidin B2 and quercetin-3-O-rutinose-7-O-rhamnoside in the supernatant decreasednoticeably. However, these two substances could not bedetected in the sediment. In summary, the formation ofsediment from litchi juice is mainly caused by the slowdenaturation of proteins and the oxidation of procyanidinB2 and quercetin-3-O-rutinose-7-O-rhamnoside.
