Fundamental questions regarding UPJO's mechanism, assessment, and treatment still remain unanswered. The aim of the present study was to elucidate potential differences through serum metabolic profiling of surgical cases of infants with UPJO compared to both nonsurgical cases and healthy age-matched controls. Early diagnosis of renal dysfunction in this cohort based on highlighted biomarkers was the ultimate goal. Thus, serum samples were collected from 20 patients preoperatively, 19 patients with mild stenosis treated conservatively, and 17 healthy controls. All samples were subjected to targeted metabolomics analysis by hydrophilic interaction liquid chromatography coupled to mass spectrometry (HILIC LC-MS/MS). Both univariate and multivariate statistical analyses were performed. Principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA) score plots showed that the studied groups differed significantly, with a panel of metabolites, including creatinine, tryptophan, choline, and aspartate, distinguishing patients who required surgery from those followed by systematical monitoring as well as from healthy controls, showing high performance as indicators of UPJO disease.Erythrodiol, a typical pentacyclic triterpenic diol in olive oil and its byproduct, olive pomace, frequently appears in food additives for the prevention of cardiovascular disease because of its antioxidation, anti-inflammatory and antitumor activities. To develop new derivatives of erythrodiol (1), preparative biotransformations were investigated through Streptomyces griseus ATCC 13273, Penicilium griseofulvum CICC 40293, Bacillus subtilis ATCC 6633, and ten new (1a-1j) and one known metabolites were isolated. Their structures were elucidated by HR-ESI-MS and 1D and 2D NMR spectroscopy. Furthermore, relative to 1, most metabolites exhibited lower toxicity and more potent inhibitory activities against nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. In particular, the glycosylated metabolite 1k showed a dramatically increased inhibitory effect with an IC50 value of 2.40 μM, which is even lower than that of quercetin. Thus, biotransformation of erythrodiol is a viable strategy for discovering new triterpenes as food supplements with anti-inflammatory properties.A novel method for the one-pot synthesis of diannulated 1,4,2-diazaphospholium triflate salts by a Me3SiOTf-mediated self-condensation of dichlorophosphanyl aza-(Poly)cyclic Aromatic Hydrocarbons (aza-(P)AHs; namely pyridine, quinoline, phenan-thridine and benzo[d]thiazole) is reported. The diannulated 1,4,2-diazaphospholium triflate salts are characterized by multi nuclear NMR spectroscopy, X-ray analysis as well as their calculated NICS values, underlining their aromatic character. Quantum mechan-ical calculations shed light on the intermolecular reaction mechanism. Follow up chemistry, such as halogenation reaction with XeF2 or SO2Cl2 with the dipyridinium derivative selectively yields the respective dihalo-σ4,λ5- and tetrahalo-σ5,λ6-diazaphospholium triflate salts. The dihalo-σ4,λ5-diazaphospholium triflate salt serves well as surrogate for the introduction of the cationic 2-(1,2'-bipyridin)-1-iumyl ligand (1,2'-bipyl), the monocationic structural isomer of the prototypical 2,2'-bipyridine ligand (2,2'-bipy).Acyl fluorides are subjected to methoxylation with tris(2,4,6-trimethoxyphenyl)phosphine (TMPP) to afford the corresponding methyl esters in good to excellent yields. This transformation is featured by C(sp2)-OMe bond cleavage under metal-free conditions. Unprecedented utilization of TMPP as a methoxylating agent realized the installation of an OMe group into the desired products.Free-standing (Co, Ni)2P/LaF3 hollow nanotube arrays are directly grown on Ni foam (NF) (denoted as (Co, Ni)2P-La4/NF, where "4" refers to 4 g L-1 of La3+ in the starting material), which exhibits efficient electrocatalytic activity for hydrogen evolution reaction (HER) with an overpotential of 94 mV at 10 mA cm2, Tafel slope of 88 mV dec-1, and superior long-term durability in alkaline electrolyte. Investigated was La dosage-induced compositional and morphological evolution of (Co, Ni)2P/LaF3, and it was found that suitable La dosage is beneficial for the epitaxial growth of (Co, Ni)2P on LaF3 nanosheets (the thickness direction of LaF3 nanosheet is along the (03i̅) facet), leading to the formation of porous (Co, Ni)2P/LaF3 nanotube walls, giving rise to hollow nanotube arrays. The binder-free (Co, Ni)2P-La4/NF electrode with unique morphology not only provides more active sites exposure to electrolyte ions and accessible ion diffusion path but also favors electron and charge transfer. Density functional theory calculation and experimental data reveal the doping of La into metal phosphide can lead to electron transfer from metal centers to P atoms, make the ΔGH on the P sites closer to zero with lower H2O adsorption energy (-0.58 eV), thus improving the HER behavior. The present work gives a novel strategy to design hollow nanotubular microstructure as non-noble-metal HER electrocatalyst.Numerous ion-selective and reference electrodes have been developed over the years. Following the need for point-of-care and wearable sensors, designs have transitioned recently from bulky devices with an aqueous inner filling solution to planarizable solid-contact electrodes. However, unless the polymeric sensing and reference membranes are held in place mechanically, delamination of these membranes from the underlying solid to which they adhere physically limits sensor lifetime. Even minor external mechanical stress or thermal expansion can result in membrane delamination and, thereby, device failure. To address this problem, we designed a sensing platform based on poly(ethylene terephthalate) substrates to which polyacrylate-based sensing and polymethacrylate-based reference membranes are attached covalently. Ion-selective membranes with covalently attached or freely dissolved ionophore and ionic liquid-doped reference membranes can be directly photopolymerized onto surface-functionalized poly(ethylene terephthalate), resulting in the formation of covalent bonds between the underlying substrate and the attached membranes.
