Density functional theory calculations are employed to study the mechanism of photoselective catalytic reduction of 4-bromobenzaldehyde (4-BBA) in acetonitrile and in ethanol solvents. A totally relaxed Ti3O9H6 cluster model is proposed to represent titanium dioxide (TiO2) surfaces. The reduction selectivity of an adsorbed 4-BBA molecule on Ti3O9H6 has been investigated. Owing to the difference in the proton and H atom donating capabilities between explicit CH3CN and C2H5OH solvent molecules, the photocatalytic reduction of 4-BBA is the debromination process in acetonitrile, whereas in ethanol it is the carbonyl reduction process...

The prevalence of lower urinary tract symptoms (LUTS) and benign prostatic hyperplasia (BPH) increases with age. While a variety of treatments are available for these men, endoscopic treatments are generally preferred for men with small to moderate size glands. Novel treatment options are continually introduced into this large market. However, the practicing urologist should have a well tested surgical option in regular practice that is applicable to a wide range of patients. Herein we discuss two well recognized surgical options that can be used for the majority of men with LUTS due to BPH who have failed medical management...

Benign prostatic hyperplasia (BPH) is a common pathology causing lower urinary tract symptoms (LUTS) and may significantly impact quality of life. While transurethral resection of the prostate (TURP) remains the gold standard treatment, there are many evolving technologies that are gaining popularity. Photoselective vaporization of the prostate (PVP) is one such therapy which has been shown to be non-inferior to TURP. We aimed to review the literature and discuss factors to optimise patient outcomes in the setting of PVP for BPH...
