miR-1247-3p regulation of CCND1 affects chemoresistance in colorectal cancer.

The effectiveness of chemotherapy involving 5-fluorouracil and cisplatin (DDP) for the treatment of colorectal cancer (CRC) is often limited due to the emergence of drug resistance. An increasing body of research highlights the crucial role of abnormally expressed microRNAs (miR/miRNAs) in fostering drug resistance in various types of cancer. The present study was the first to explore the potential roles and mechanisms of the small non-coding RNA miR-1247-3p in CRC, particularly its association with DDP resistance in CRC.

3D Ordered Macroporous Mn, Zr-Doped CaCO Nanomaterials for Stable Thermochemical Energy Storage.

Developing high-performance Ca-based materials that can work for long-term heat transfer and storage in concentrated solar power plants is crucial to achieve the large-scale conversion of solar photon fluxes to dispatchable electricity. This work demonstrates that a series of Mn, Zr co-doped CaCO nanomaterials with the 3D ordered macroporous (3DOM) skeletons are successfully prepared by a novel strategy of templated metal salt co-precipitation. The characterization results indicate that a majority of Zr and Mn are atomically dispersed into the highly-crystallized CaCO framework, whereas a minor amount of Mn is present in the form of CaMnO nanoparticles (NPs).

Theoretic Study of Sulfur-Doped Graphdiynes by X-ray Spectroscopy.

Sulfur-doped graphdiyne at different sites has a tremendous impact on its electronic structure and properties. Due to the large number of S-doping sites, there is no comprehensive and systematic experimental and theoretical study regarding the identification of S-doped graphdiyne configurations. In this paper, X-ray photoelectron (XPS) and near-edge X-ray absorption fine structure (NEXAFS) spectra as well as geometries of 10 sulfur-doped graphdiyne molecules have been simulated at the density functional theory (DFT) level.

SiCN monolayer as a universal anode for alkali metal-ion batteries.

Our density functional theory calculations show that silicon doping in g-CN (SiCN) can improve the electrochemical performance of g-CN as an anode of alkali metal-ion batteries and solve the problems of too high adsorption ability and migration energy barrier commonly found in porous carbon nitride. The stability of SiCN was verified by molecular dynamics simulations and phonon spectroscopy. Elastic constant calculations revealed that the Si doping in g-CN can improve its mechanical properties.

Positive coping style reduction in elderly end-stage renal disease patients: mediating role of white matter mean diffusivity.

Purpose: The aim of this study was to explore elderly patients with end-stage renal disease (ESRD) white matter changes, the relationship between white matter (WM) abnormalities and emotional regulation strategies, coping styles in elderly ESRD patients.

Methods: Twenty-eight elderly ESRD patients and twenty-eight sex and age matched healthy controls (HC) were included in this study. Tract-based spatial statistic (TBSS) was used to investigate the microstructural changes of WM.
