Background: Transrectal ultrasound-guided prostate biopsy (TRBx) or transperineal Bx (TPBx) are considered alternative approaches for the diagnosis of prostate cancer (PCa). However, urinary tract infection (UTI) or other complications could be more frequent in the TRBx approach. Objective: To determine the complication rate following different antimicrobial prophylaxis (AMP; fosfomycin trometamol [FT] vs beta-lactame or fluorochinolones [FQ]) in patients undergoing TRBx or TPBx. Design, setting, and participants: The analyses were based on prospectivelycollected data of a cohort of patients who underwent TRBx or TPBx for elevated prostate-specific antigen (PSA; >= 4 ng/ml) or clinical suspicion of PCa, between September 2016 and March 2017. Patients received a single dose of 3 g oral FT (group A) or, alternatively, FQ or beta-lactame (group B). Intervention:TRBx versus TPBx. Outcome measurements and statistical analysis: Adjustment variables consisted of age, PSA, biopsy technique (TPBx vs TRBx), and antibiotic prophylaxis (FT vs beta-lactame or FQ) using 1:1 propensity-score matching. Overall, 526 patients were considered, of whom 258 received FT (group A) and the other 258 received beta-lactame or FQ (group B). Results and limitations: Overall complications occurred in 390 (75.58%) and major complications in 67/516 (12.98%). Lower prevalence of UTIs was detected in group A (34.1%) compared with that in group B (43.4%; p = 0.03), while similar rates of haematuria (54.7% vs 55.4%), haemospermia (39.5% vs 33.0%), and acute urinary retention (11.6% vs 9.3%) were detected in groups A and B. We found that group B (odds ratio [OR]: 1.54; p = 0.03), I grade haematuria (OR: 6.17; p < 0.01), and II grade haematuria (OR: 5.13; p < 0.01) were significantly associated with increased risk of UTIs. Conclusions: AMP with fluoroquinoles or beta-lactam antibiotics increased the rate of UTIs, when compared with FT, in patients undergoing TRBx or TPBx. The appearance of haematuria or haemospermia is associated with UTIs, suggesting the possibility of tailoring the strategy for prophylaxis in this category of patients. Patient summary: In this study, comparing complications after transrectal ultrasound-guided prostate biopsy versus transperineal biopsy, prophylaxis with fluoroquinoles or beta-lactam antibiotics increased the rate of urinary tract infections when compared with fosfomycin trometamol, regardless of the type of biopsy approach.

A practical means to quantify the response of the rates of net N mineralization and denitrification over a wide range of soil water contents is generally lacking. This study examined the potential to use a nitrification inhibitor (NI) assay system to simultaneously estimate the rates of net N mineralization and denitrification, and applied the NI assay to assess the effect of water content on net N mineralization and denitrification rates in two soils with contrasting soil texture. The compound 3,5-dimethylpyrazole (DMP) applied at a rate of 200 mg kg(-1) was found to provide essentially complete inhibition of nitrification over the duration of the soil incubation for two soils with contrasting soil texture (clay loam vs. sandy loam) and over a range of soil water contents (35%, 55%, and 85% water-filled pore space). This allowed net N mineralization to be estimated as the accumulation of soil ammonium (NHthorn 4) and of denitrification as the disappearance of added nitrate (NO3-). Addition of DMP resulted in a small increase in soil respiration rate but did not appear to influence the rate of net soil N mineralization. The NI assay provides a practical means to quantify the rates of net N mineralization and denitrification simultaneously over a wide range of soil water contents. The assay can be readily scaled up to routinely test multiple soils in an efficient manner, has limited material costs, and is also relatively simple to perform.

Poly(3,4-ethylenedioxythiophene) (PEDOT) doped with a new sulfonated derivate from bis(3,5-dimethylpyrazol-1-yl)methane (LSA) was electrochemically synthesized and characterized by cyclic voltammetry, chronoamperometry, scanning electron microscopy, Raman spectroscopy and ultraviolet/visible spectroscopy. In addition, LSA was also fully characterized. A PEDOT:LSA modified electrode was used to study the electrochemical detection of dopamine in the presence of ascorbic and uric acid. The use of this new dopant increased the sensitivity and reduced the detection limit compared with the values observed for PEDOT doped with perchlorate.

The study of the relationship between intermolecular interactions present in the solvation process and the magnitude of thermodynamic properties is extended from imidazole to pyrazole derivatives. The enthalpies of solution of pyrazole, 3,5-dimethylpyrazole and 3,4,5-trimethylpyrazole were calorimetrically determined in the solvents water, methanol and acetonitrile. The enthalpy of solution values for the three compounds in the three solvents are endothermic and spontaneous with an increase in entropy. As in the case with imidazole derivatives, the formation of a solution of pyrazole derivatives creates liquids that are more structured thermodynamically. The enthalpy of sublimation for 3,4,5-trimethylpyrazole, which is not available in the literature, was determined by the Knudsen effusion method. The combination of these thermodynamic properties has allowed the corresponding enthalpies of solvation to be obtained for the three pyrazole derivatives in the three selected solvents. With the use of the Pierotti equations and the enthalpies of solvation, the enthalpies of cavity formation were calculated along with the corresponding solute-solvent enthalpies of interaction. The infrared spectra and molecular volumes, as estimated through the electronic density, were used to obtain molecular insights into the solvation sensible sites within the studied solute molecules. The discussion of the solvation process and enthalpies of interaction of the pyrazole derivatives is based on the molecular structural features of solutes, specific intermolecular interactions and protic or aprotic nature of the solvents. The use of any empirical parameters in the discussion of the results was avoided. (C) 2020 Elsevier B.V. All rights reserved.

Electrocatalytic hydrogenation is a particularly attractive approach for converting the most unstable compounds in biogenic feedstocks at ambient conditions without external H-2. Here, we synthesized a variety of carbon-supported transition metal catalysts and characterized their activity for the electrocatalytic hydrogenation of a series of model compounds and pyrolysis bio-oil. Carbonyl compounds, especially aromatic aldehydes, such as furfural and benzaldehyde, are particularly inclined to hydrogenation driven by an applied current. This was verified with pure solutions of the model compounds and with pyrolysis bio-oil, where we achieved stable and steady continuous operation on Pd. When optimal catalyst composition was chosen, the conversion of benzaldehyde shifted from alcohol production (e.g., on Pd and Cu) to dimerization (e.g., on Co, Ni, and Zn). Pd and Cu were shown to offer the best compromise between reaction rates and efficiency although, in general, base metals offer similar conversions but better efficiencies than noble metals. Thus, the present work offers foundational results and guidelines for choosing the optimal metal catalyst and the applied potential for processing organic feedstocks as a function of its composition.

Bisphenol A (BPA) is a potential endocrine disruptor. It causes hormonal imbalances and also affects aquatic organisms when discharged in untreated form into the ecosystems. Many attempts have been made to degrade BPA in the liquid phase using chemical and or biological methods, which often require multiple steps and are not effective to any great extent. In this study, solution plasma process (SPP) was adopted for the degradation of BPA in liquid phase. BPA at a constant concentration (100 mg. mL(-1)) was degraded using SPP at various of discharge times (0-45 min) and various pH (3-6). Physical conditions for SPP were voltage at 800 V, frequency 35 kHz with bandwidth of 2 mu S and unipolar and bipolar power supplies were used. The degraded BPA was extracted and investigated for the degradation adopting Gas chromatography-Mass Spectroscopy (GC-MS). During SPP, intermediates were formed at 15 min of treatment, and degradation was achieved to a maximum of 86% at 18 min. The GC-MS results revealed that dimethyl ester (91%), hydroxyl-bicyclooctenone (56%), imidazole (23%), pyridine (10%) and benzene (9%) fragments were formed abundantly due to plasma treatment. Plasma-treated BPA was not toxic to aquatic fern, Lemna minor as revealed in relative growth rate (RGR(area)) analysis. SPP causes release of free radicals, which are actively involved in BPA degradation without any additive chemicals. The approach in this study could be projected as an effective SPP-based clean-technology for degradation of toxicants in the aquatic ecosystems and also for effective wastewater treatment.
