Long noncoding RNAs (lncRNAs) have been reported to play an important role in diabetic nephropathy (DN). However, the molecular mechanism involved this process remains poorly understood. Thus, present study aimed explore function and of dysregulated lncRNA X-inactive specific transcript (XIST) DN. DN mouse models were established by streptozotocin treatment, human renal tubular epithelial HK-2 cells exposed high glucose produce vitro model. XIST was highly expressed tissues patients with DN,...
Abstract A cobalt porphyrin complex with a pendant imidazole base ([(L 1 )Co II ]) is an efficient catalyst for the homogeneous catalytic two‐electron reduction of dioxygen by 1,1′‐dimethylferrocene (Me 2 Fc) in presence triflic acid (HOTf), as compared without ]). The ligand plays crucial role not only to provide imidazolinium proton proton‐coupled electron transfer (PCET) from [(L ] O HOTf but also facilitate (ET) absence HOTf. kinetics analysis and detection intermediates stoichiometric...
Introduction of Brønsted acids into biomimetic nonheme reactions promotes the oxidative ability metal-oxygen complexes significantly. However, molecular machinery promoted effects is missing. Herein, a comprehensive investigation styrene oxidation by cobalt(III)-iodosylbenzene complex, [(TQA)CoIII(OIPh)(OH)]2+ (1, TQA = tris(2-quinolylmethyl)amine), in presence and absence triflic acid (HOTf) was performed using density functional theory calculations. Results revealed for first time that...
In this paper, we report the preparation, spectroscopic and theoretical characterization, reactivity studies of a Co(IV)-oxo complex bearing an N4-macrocyclic coligand, 12-TBC (12-TBC = 1,4,7,10-tetrabenzyl-1,4,7,10-tetraazacyclododecane). On basis ligand structure Co(II) precursor, [CoII(12-TBC)(CF3SO3)2], one would assume that species corresponds to tetragonal complex, but data do not support notion. Co K-edge XAS show treatment precursor with iodosylbenzene (PhIO) as oxidant at -40 °C in...
Abstract A mononuclear nonheme cobalt(III) iodosylbenzene complex, [Co III (TQA)(OIPh)(OH)] 2+ ( 1 ), is synthesized and characterized structurally spectroscopically. While a sluggish oxidant in oxidation reactions, it becomes competent oxygen atom transfer such as olefin epoxidation, the presence of small amount proton. More interestingly, shows nucleophilic reactivity aldehyde deformylation reaction, demonstrating that has an amphoteric reactivity. Another interesting observation can be...
Acute cerebrovascular accidents, long-term hypoperfusion, and/or remote neuronal degeneration may lead to structural alterations in patients with moyamoya disease (MMD). This study sought comprehensively investigate the distribution characteristics of subcortical gray matter volume and their correlations angiographic changes intracranial artery MMD.One hundred forty-two MMD 142 age- sex-matched healthy controls underwent 3-dimensional high-resolution magnetic resonance imaging. Volumes...
We report the synthesis and characterization of a mononuclear nonheme cobalt(III)-imidyl complex, [Co(NTs)(TQA)(OTf)]+ (1), with an S = 3/2 spin state that is capable facilitating exogenous substrate modifications. Complex 1 was generated from reaction CoII(TQA)(OTf)2 PhINTs at −20 °C. A flow setup ESI-MS detection used to explore kinetics formation, stability, degradation pathway in solution by treating Co(II) precursor PhINTs. Co K-edge XAS data revealed distinct shift compared precursor,...

Abstract Thermolysis of Ru 3 (CO) 12 with carboxylic acids directly accessed a large variety low valence ruthenium carbonyl complexs. Under the conditions reaction firstly reported by J. Lewis, equivalents were employed to assembly sawhorse‐type dirutheniumtetra complex. Six ‐Ru 6 clusters unexpectedly isolated in 1 equivalent under thermal condition. The ten kind systematically investigated. reactions non‐coordinative afforded β‐H 2 4 13 ( ), (μ ‐C)(μ‐CO)(CO) 16 ) and then (η ‐C H 5 CH...
