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.

This study was aimed to identify volatile compounds of 31 green coffee bean samples and evalute their correlation with altitude of the coffee plants grown in two zones (Gedeo and Jimma) in Ethiopia. A total of 81 different compounds were detected. The contents of dominant volatile compounds in green coffee beans were in the range: trans-linalooloxide (3.24-19.13%), linalool (1.56-21.76%), 2-methoxy-4-vinylphenol (2.34-15.08%) and cis-linalooloxide (1.03-13.27%). In addition, benzene acetaldehyde (0.45-10.97%), 2-heptanol (0.67-8.49%), alpha-terpineol (0.64-6.52%), phenylethyl alcohol (0.44-4.98%) and furfural (0.92-5.3%) were the next dominant compounds. The volatile compounds identified in the green coffee beans are groups of alcohols, aldehydes, ketones, pyrazines, pyridines, and furans. The volatile compounds in green coffee beans showed either weak positive or weak negative correlation with the altitude of coffee plants indicating that variation in altitude of the coffee plants does not significantly influence the volative compounds of green coffee beans.

Four new coordination compounds of nickel (II) with derivatives of N,N-bis(pyrazol-1-ylmethyl)propylamine were synthesized; their composition and structure were confirmed with IR-spectroscopy and elemental analysis. The structures of products 13 and 15 were unambiguously established in an X-ray diffraction study. Compounds 13 and 15 crystallize in the orthorhombic space groups Pna2(1) and P2(1)2(1)2(1) correspondingly and represent a monomeric octahedral nickel complexes, that are typical for tridentate scorpion-type ligands. New method for immobilization of nickel complexes with derivatives of N,N-bis(pyrazol-1-ylmethyl)propylamine on silica gel modified with aminopropyl groups was proposed. The EXAFS/XANES analysis indicated that Ni atom in the supported complexes adopt almost octahedral geometry, being partly surrounded by nitrogen atoms from organic ligand and partly grafted to silica surface through silanol groups, with Br- in outer coordination sphere. Both the original and the supported complexes, when activated with Et2AlCl or Et3Al2Cl3, catalyze ethylene oligomerization with the predominant formation of butene isomers. Generally, the immobilized complexes show higher activity and better selectivity towards 1-butene formation.

3-Aminothieno[2,3-b]pyridine-2-carboxylic acid esters readily reacted with 3,5-dimethyl-1-(cyanoacetyl)-1H-pyrazole to give previously unknown N-(thieno[2,3-b]pyridin-3-yl)cyanoacetamides. Reactions of the latter with 2-(arylmethylidene)malononitriles were nonselective, and mixtures of different heterocyclization products were generally formed. The cyclization of ethyl 4,6-dimethyl-3-[(cyanoacetyl)amino]thieno[2,3-b]pyridine-2-carboxylate afforded 2,4-dihydroxy-7,9-dimethylthieno[2,3-b : 4,5-b’]dipyridine-3-carbonitrile whose tautomeric equilibrium was studied by DFT quantum chemical calculations. In silico analysis of biological activity of the synthesized compounds was performed.

We have reported the synthesis, characterization, and catalytic applications of amorphous iron nanoparticles (FeNPs) using aqueous leaves extract of renewable natural resourceBoswellia serrataplant. Synthesized FeNPs were stabilized in situ by the addition of aqueous pod extracts ofAcacia concinnaas a biosurfactant (pH 3.11). The structural investigation of biosynthesized nanoparticles was performed using UV-visible spectroscopy, X-ray diffraction analysis, selected area electron diffraction, energy-dispersive X-ray spectroscopy, scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, thermogravimetric analysis, and BET analysis. The FeNPs were amorphous in nature with average particle size similar to 19 nm and successfully employed as heterogeneous catalyst for the synthesis of quinoxaline, benzimidazole, and pyrazole derivatives in aqueous medium at ambient conditions. The FeNPs could be recycled up to five times with modest change in the catalytic activity. [GRAPHICS] .

Catalyst deactivation caused by the aggregation of active metal species in the reaction process poses great challenges for practical applications of supported metal catalysts in solid-liquid catalysis. Herein, we develop a hypercrosslinked polymer integrated with N-heterocyclic carbene (NHC) as bifunctional support to stabilize palladium in heterogeneous C-C bond formations. This polymer supported palladium catalyst exhibits excellent stability in the one-pot fluorocarbonylation of indoles to four kinds of valuable indole-derived carbonyl compounds in cascade or sequential manner, as well as the representative Suzuki-Miyaura coupling reaction. Investigations on stabilizing effect disclose that this catalyst displays a molecular fence effect in which the coordination of NHC sites and confinement of polymer skeleton contribute together to stabilize the active palladium species in the reaction process. This work provides new insight into the development of supported metal catalysts with high stability and will also boost their efficient applications in advanced synthesis.

We report the promoting effect of graphitic carbon nitride in Cu-catalyzed N-arylation. The abundance of pyridinic coordination sites in this host permits the adsorption of copper iodide from the reaction medium. The key to achieving high activity is to confine active Cu species on the surface, which is accomplished by introducing atomically dispersed metal dopants to block diffusion into the bulk of the carrier. The alternative route of incorporating metal during the synthesis of graphitic carbon nitride is ineffective as Cu is thermodynamically more stable in inactive subsurface positions. A combination of X-ray absorption, X-ray photoelectron, and electron paramagnetic resonance spectroscopy, density functional theory, and kinetic Monte Carlo simulations is employed to determine the location and associated geometry as well as the electronic structure of metal centers. N-Arylation activity correlates to the surface coverage by copper, which varies during the reaction due to an interplay between site formation via adsorption from the reaction medium and deactivation by diffusion into the bulk of the material, and is highest when an Fe dopant is used to hinder such movement through the lattice.

A lithium chloride catalyzed aza-Michael reaction of pyrazoles to alpha,beta-unsaturated imides has been developed. A range of aromatic and aliphatic alpha,beta-unsaturated imides are found to be suitable for the established method, providing the corresponding aza-Michael adducts in up to 93% yields. The inexpensive catalyst, good substrate tolerance, and ease of scale-up make this procedure highly practical.

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.

A series of new 9,9-diethylfluorenes consisting of three side-arms each bearing a heterocyclic, bis(carboxymethyl)amino, bis(carbamoylmethyl)amino, bis(ethoxycarbonylmethyl)amino or an amino group were prepared on the basis of 2,4,7-tris(bromomethyl)-9,9-diethylfluorene. Imidazolyl, benzimidazolyl, pyrazolyl, pyrrolyl, 1,3-dioxoisoindolyl and pyridinium groups were taken into account as heterocyclic units, attached to the aromatic skeleton via -CH2-, -CH2NHCH2- or -CH2N=CH- linkers. In addition to the seventeen 2,4,7-trisubstituted 9,9-diethylfluorenes, two macrocyclic compounds were prepared on the basis of 2,7-bis(aminomethyl)-9,9-diethylfluorene. The excellent yield of the macrocyclization reaction is worth a special mention. Both the acyclic and the macrocyclic fluorene-based compounds have, among other things, the potential to act as artificial receptors for different substrates in analogy to the known receptors consisting of a benzene or biphenyl core.
