Characteristics of multi-mode lasing in cesium lead bromide perovskite microwires with an isosceles right triangle cross-section.

The CsPbBr microwires with unique isosceles right triangle cross-sections are commonly observed via chemical vapor deposition method. In this work, we study the correlations between measured multi-mode lasing behaviors and the simulation of the mode patterns inside the triangular-rod microcavity. We confirm that lasing action with higher-order transverse modes can well sustain, even when these modes experience large optical loss due to the isosceles triangle cross-section.

Wdhd1 is essential for early mouse embryogenesis.

WD repeat and HMG-box DNA binding protein 1 (Wdhd1) is the mouse ortholog of budding yeast Chromosome Transmission Fidelity 4 (CTF4), the protein product of which integrates the MCM2-7 helicase and DNA polymerase α/primase complex to initiate DNA replication. Previous work in fruit flies, Xenopus egg extracts, and human cell lines suggest that Wdhd1 is required for efficient DNA synthesis. However, rigorous in vivo functional studies on Wdhd1 in mammals are unavailable.

High-Performance Perovskite-Based Light-Emitting Diodes from the Conversion of Amorphous Spin-Coated Lead Bromide with Phenethylamine Doping.

Large-grained and well-oriented methylammonium lead tribromide (MAPbBr) perovskite was formed from the conversion of amorphous lead bromide (PbBr) doped with phenethylamine (PEA). The addition of PEA ions (with an optimized molar ratio of 0.008%) to the PbBr solution assisted the formation of a smooth PEA-doped PbBr layer by spin-coating.

Role of Dicer in regulating oxaliplatin resistance of colon cancer cells.

Colorectal cancer (CRC) is a major health problem due to its high mortality rate. The incidence of CRC is increasing in young individuals. Oxaliplatin (OXA) is an approved third-generation drug and is used for first-line chemotherapy in CRC.

The EGF/hnRNP Q1 axis is involved in tumorigenesis via the regulation of cell cycle-related genes.

Heterogeneous nuclear ribonucleoprotein (hnRNP) Q1, an RNA-binding protein, has been implicated in many post-transcriptional processes, including RNA metabolism and mRNA splicing and translation. However, the role of hnRNP Q1 in tumorigenesis remains unclear. We previously performed RNA immunoprecipitation (RIP)-seq analysis to identify hnRNP Q1-interacting mRNAs and found that hnRNP Q1 targets a group of genes that are involved in mitotic regulation, including Aurora-A.
