[Value of serum miR-21-3p in predicting acute kidney injury in children with sepsis].

Objective: To study the value of serum miR-21-3p combined with serum creatinine (Scr), cystatin C (Cys-C), and kidney injury molecule-1 (KIM-1) in predicting acute kidney injury (AKI) in children with sepsis.

Methods: A total of 142 children who were diagnosed with sepsis from January 2016 to March 2019 were enrolled. According to the presence or absence of AKI, they were divided into AKI group with 49 children and non-AKI group with 93 children.

Role of External Field in Polymerization: Mechanism and Kinetics.

The past decades have witnessed an increasing interest in developing advanced polymerization techniques subjected to external fields. Various physical modulations, such as temperature, light, electricity, magnetic field, ultrasound, and microwave irradiation, are noninvasive means, having superb but distinct abilities to regulate polymerizations in terms of process intensification and spatial and temporal controls. Gas as an emerging regulator plays a distinctive role in controlling polymerization and resembles a physical regulator in some cases.

Mediation of Electron Transfer by Quadrupolar Interactions: The Constitutional, Electronic, and Energetic Complementarities in Supramolecular Chemistry.

Studies of intermolecular interactions enhance our knowledge of chemistry across molecular and supramolecular levels. Here, we show that host-guest quadrupolar interaction has a profound influence on the molecular system. With covalently bonded dimolybdenum complex units as the electron donor (D) and acceptor (A) and a thienylene group (CHS) as the bridge (B), the mixed-valence D-B-A complexes are shaped with clefts in the middle of the molecule.

Efficient electron transfer across hydrogen bond interfaces by proton-coupled and -uncoupled pathways.

Thermal electron transfer through hydrogen bonds remains largely unexplored. Here we report the study of electron transfer through amide-amide hydrogen bonded interfaces in mixed-valence complexes with covalently bonded Mo units as the electron donor and acceptor. The rate constants for electron transfer through the dual hydrogen bonds across a distance of 12.

Optically probing the localized to delocalized transition in Mo-Mo mixed-valence systems.

Four thienylene (CHS) bridged Mo dimers, [Mo(DAniF)](μ-OOCCHSCOO) (DAniF = N,N'-di(p-anisyl)formamidinate), [Mo(DAniF)](μ-N(H)SCCHSCN(H)S), [Mo(DAniF)](μ-OSCCHSCSO) and [Mo(DAniF)](μ-SSCCHSCSS), have been synthesized and studied in terms of electronic coupling. The subtle structural differences between these compounds vary largely the extent of electron delocalization; consequently, a systematic transition from Class II to Class III via Class II-III is achieved, which is probed using spectral parameters of intervalence charge transfer (IVCT) absorption (band energy, intensity and shape) for the mixed-valence complexes. Significantly, the species in Class II-III displays a low energy, half cut-off and solvent-dependent IVCT band, while a high energy, less asymmetrical IVCT band is observed for the complex in Class III.

A bifunctional solid oxide electrolysis cell for simultaneous CO utilization and synthesis gas production.

We hereby report on a pioneering and inspiring solid oxide cell which, assisted by natural gas, utilizes a bifunctional electrolysis cell configuration to effectively consume CO to produce CO at the cathode side and simultaneously synthesize highly valuable syngas (mixture of CO and H) at the anode side via a one-step green process.

[MicroRNAs and cancer-associated signal transduction pathways].

Signal transduction pathways play extremely important roles in various processes of cell life including metabolism, growth, proliferation, stress, development and apoptosis. Disruption of these pathways may affect normal cell growth and development, and even gives rise to tumors. MicroRNAs (miRNAs) are a newly discovered class of non-coding small RNAs (approximately 22 nucleotides in length) in eukaryotes that negatively regulate gene expression at the post-transcriptional level.

[Study on trace elements in wuji baifeng wan and its preparation].

We studied the amount of trace elements in the traditional Chinese medicine Wuji Baifeng Wan by cluster analysis, and found that the clustering results of the trace elements in Twelve Wuji Baifeng Wan (the southern preparation) and Wuji Baifeng Wan (the northern preparation) were not in the same group. In this paper, AAS was used for the determination of trace elements in Wuji Baifeng Wan and its preparation. The results showed that there were great differences between Twelve Wuji Baifeng Wan and Wuji Baifeng Wan , while the difference between Chinese Taihe Chicken and Native Chicken was slight.
