An effective procedure for selective reduction of O2 to H2O2 exploring the use of hydrogen sulfide, an obnoxious industrial pollutant as reductant is reported herein. The reduction of [Ru(III)(EDTA)pz](-) (EDTA(4-) = ethylenediaminetetraacetate; pz = pyrazine) by hydrogen sulfide resulting in the formation of a red [Ru(II)(EDTA)pz](2-) complex (λmax = 462 nm) has been studied spectrophotometric...

Prostate cancer (PCa) is a clinically heterogeneous and multifocal disease with a clinical outcome that is difficult to predict. Notably, predisposition to develop prostate cancer is different among the prostate zones, with the peripheral zone (PZ) or prostate proper as the most frequent site compared to the transitional zone (TZ). Translocations ...

Several plant products are used as antioxidant agents to treat inflammation-related disorders. In recent years, encapsulation of biologic active compounds in lipid vesicles was shown to improve their bioavailability and transdermal delivery. The aim of this study was to prepare two arnica extracts of polyphenols (Pf) and polysaccharides (Pz) and their liposomal formulations (LPf, L-Pz) and to c...

A supramolecular dual emissive system incorporating two classical copper(I)-cluster-based luminophores, namely, Cu(4)I(4) and Cu(3)Pz(3) (Pz = pyrazolate), is reported. The targeted luminescent coordination polymer exhibits reversible thermochromism spanning from green to orange-red.

For a fixed prime p, we consider the set of maps Z/pZ → Z/pZ of the form a 7→ Tn(a), where Tn(x) is the degree-n Chebyshev polynomial of the first kind. We observe that these maps form a semigroup, and we determine its size and structure.

To assess the role of time-intensity curves (TICs) of the normal peripheral zone (PZ) in the identification of biopsy-proven prostate nodules using contrast-enhanced transrectal ultrasound (CETRUS). This study included 132 patients with 134 prostate PZ nodules. Arrival time (AT), peak intensity (PI), mean transit time (MTT), area under the curve (AUC), time from peak to one half (TPH), wash in ...

The prostate gland is conventionally divided into zones or regions. This morphology is of clinical significance as prostate cancer (CaP) occurs mainly in the peripheral zone (PZ). We obtained tissue sets consisting of paraffin-embedded blocks of cancer-free transition zone (TZ) and PZ and adjacent CaP from patients (n = 6) who had undergone radical retropubic prostatectomy; a seventh tissue set...

BACKGROUND Data on the association between the interleukin-1 (IL-1) gene polymorphisms and Graves' disease (GD) risk were conflicting. A meta-analysis was undertaken to assess this association. METHODS We searched for case-control studies investigating the association between the IL1B (-511), IL1B (+3954), IL1RN (VNTR) polymorphisms and GD risk. We extracted data using standardized forms and ...

The main challenges to the commercial deployment of solvent-based post-combustion carbon capture technology include high energy consumption and capital operating costs. New solvents alternative process configurations are being pursued reduce costs process. This paper investigates technical economic performance using piperazine (PZ) solvent for a 250 MWe natural gas combined cycle power plant. T...
