Abstract
Hydrogen-bonded aggregates of B(C6F5)3 and water are proven as strong Brønsted acid catalysts, which have the advantages of low toxicity and broad compatibility. Sulfoxonium ylides are stable surrogates of diazo compounds, which participate in various reactions due to their versatile reactivity. Based on these characteristics, a strategy for C-N bond or C-C bond construction of aromatic amines with sulfoxonium ylides under metal-free catalytic conditions was established. This method has advantages of mild conditions and excellent yield, which is suitable for the N-H or C-H functionalization of various aromatic amine compounds.

Zhao J, Chen W, Liu J. Lycopene ameliorates locomotor activity and urinary frequency induced by pelvic venous congestion in rats. Open Med (Wars) 2023; 18:20230638. [PMID: 36865495 PMCID: PMC9971737 DOI: 10.1515/med-2023-0638] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 11/17/2022] [Accepted: 12/19/2022] [Indexed: 02/27/2023] Open
Abstract
Decreased locomotor activity and altered urinary frequency are induced by bilateral common iliac vein ligation in rats. As a carotenoid, lycopene has a strong anti-oxidative function. This research investigated the function of lycopene in the pelvic venous congestion (PC) rat model and the underlying molecular mechanism. Lycopene and olive oil were administered intragastrically on a daily basis for 4 weeks after successful modeling. Locomotor activity, voiding behavior, and continuous cystometry were analyzed. The levels of 8-hydroxy-2'-deoxyguanosine (8-OHdG), nitrate and nitrite (NO x ), and creatinine in the urine were measured. Gene expression in the bladder wall was analyzed by quantitative reverse transcription polymerase chain reaction, enzyme-linked immunosorbent assay, and Western blot. Locomotor activity, single voided volume, the interval between the bladder contractions, and urinary NO x /cre ratio were all decreased in rats with PC, while the frequency of urination, urinary 8-OHdG/cre ratio, inflammatory responses, and nuclear factor-κB (NF-κB) signal activity were all increased. Lycopene treatment increased locomotor activity, decreased frequency of urination, elevated urinary NO x level, and decreased urinary 8-OHdG level in the PC rat model. Lycopene also inhibited PC-enhanced pro-inflammatory mediator expression and NF-κB signaling pathway activity. In conclusion, lycopene treatment ameliorates PC-induced phenotypes and shows an anti-inflammatory effect in the PC rat model.

Correlation Between Nitric Oxide and Urodynamics in Men With Bladder Outlet Obstruction. Int Neurourol J 2021; 26:S15-21.

Abstract
Purpose To investigate the correlation between nitric oxide (NO) and urodynamics in men with bladder outlet obstruction (BOO) by analyzing nitric oxide synthase (NOS) in the urothelium. Methods We prospectively enrolled 25 men who planned to undergo surgical treatment for benign prostatic obstruction and identified as BOO in the preoperative urodynamics. Bladder tissue was taken during surgical prostate resection. Expressions of endothelial NOS (eNOS), inducible NOS (iNOS), and neuronal NOS (nNOS) in the urothelium were analyzed, and their correlation with urodynamic parameters was also assessed in all patients. We also compared the expressions of eNOS, iNOS, and nNOS between BOO with detrusor underactivity (DU) group and BOO without DU group. Results In all patients, the level of eNOS positively correlated with maximal flow rate and with maximum cystometric capacity (MCC). The level of iNOS positively correlated with MCC. nNOS levels were positively correlated with detrusor pressure at maximal flow and with bladder contractility index in all patients. The level of eNOS, iNOS, and nNOS did not significantly differ between BOO without DU group and BOO with DU group. Conclusions This study suggests that NO was correlated with bladder dysfunction in men with BOO. Particularly, nNOS may reflect the change in detrusor function.
