The etiologies and pathogenesis of dilated cardiomyopathy (DCM) with heart failure (HF) remain to be defined. Thus, exploring specific diagnosis biomarkers and mechanisms is urgently needed to improve this situation. In this study, three gene expression profiling datasets (GSE29819, GSE21610, GSE17800) and one single-cell RNA sequencing dataset (GSE95140) were obtained from the Gene Expression Omnibus (GEO) database. GSE29819 and GSE21610 were combined into the training group, while GSE17800 was the test group. We used the weighted gene co-expression network analysis (WGCNA) and identified fifteen driver genes highly associated with DCM with HF in the module. We performed the least absolute shrinkage and selection operator (LASSO) on the driver genes and then constructed five machine learning classifiers (random forest, gradient boosting machine, neural network, eXtreme gradient boosting, and support vector machine). Random forest was the best-performing classifier established on five Lasso-selected genes, which was utilized to select out NPPA, OMD, and PRELP for diagnosing DCM with HF. Moreover, we observed the up-regulation mRNA levels and robust diagnostic accuracies of NPPA, OMD, and PRELP in the training group and test group. Single-cell RNA-seq analysis further demonstrated their stable up-regulation expression patterns in various cardiomyocytes of DCM patients. Besides, through gene set enrichment analysis (GSEA), we found TGF-β signaling pathway, correlated with NPPA, OMD, and PRELP, was the underlying mechanism of DCM with HF. Overall, our study revealed NPPA, OMD, and PRELP serving as diagnostic biomarkers for DCM with HF, deepening the understanding of its pathogenesis.</p

Urea Coordinated Titanium Trichloride Ti^III[OC(NH)₂]₆Cl₃: A Single Molecular Precursor Yielding Highly Visible Light Responsive TiO₂ Nanocrystallites

A coordination complex, TiIII[OC(NH2)2]6Cl3, was first synthesized via reacting hot alcoholic solutions of TiCl3 and urea, which was subsequently employed as a molecular precursor for nanocrystalline TiO2 via thermal decomposition. Fourier transform IR spectroscopy confirmed CO→Ti coordination bond formation, while Rietveld refinement revealed a hexagonal crystal structure (space group:  P3̄c1) for the complex with a = b = 16.438(4) Å, c = 15.423(3) Å, α = β = 90°, γ = 120°, and V = 3608.9(13) Å3. Thermal decomposition and phase evolution processes of the complex were investigated in air by combined means of elemental analysis, Fourier transform IR, differential thermal analysis/thermogravimetry, X-ray diffraction, and Raman spectroscopy. Characterizations of the resultant TiO2 powders were achieved by scanning electron microscopy, high-resolution transmission electron microscopy, the Brunauer−Emmett−Teller analysis, thermal desorption spectroscopy, and UV−vis spectroscopy. Simultaneous doping of C, N, and Cl was realized upon pyrolyzing the molecular precursor in air, leading to significantly lowered direct and indirect interband transition energies of the resultant TiO2. As a consequence, the anatase nanopowders obtained at 450 and 500 °C, with specific surface areas of 97.8 and 64.1 m2/g, respectively, exhibit significantly higher efficiency than Degussa P25 in the bleaching of methyl orange solution under visible light (mainly consisting two wavelengths of 405 and 436 nm at 81:100 intensity ratio) irradiation, either at a fixed weight of TiO2 loading or at a fixed surface area of the loaded TiO2 powder
