Biotoxicity of Halide Perovskites in Mice.

Halide perovskites are crystalline semiconductors with exceptional optoelectronic properties, rapidly developing toward large-scale applications. Lead (II) (Pb ) is the core element used to prepare halide perovskites. Pb can displace key 2+ elements, including calcium, zinc and iron, that regulate vital physiological functions.

Reduced electron relaxation time of perovskite films g-CN quantum dot doping for high-performance perovskite solar cells.

Perovskite film-quality is a crucial factor to improve the photovoltaic properties of perovskite solar cells, which is closely related to the morphology of crystallization grain size of the perovskite layer. However, defects and trap sites are inevitably generated on the surface and at the grain boundaries of the perovskite layer. Here, we report a convenient method for preparing dense and uniform perovskite films, employing g-CN quantum dots doped into the perovskite layer by regulating proper proportions.

Pupil Diameter Changes after Anesthesia with Different Doses of Sufentanil under Ultrasound Monitoring.

Objective: This study aims to observe the changes in pupil diameter (PD) after anesthesia with different doses of sufentanil with the ultrasound method and observe whether pupil contraction is correlated with hemodynamic changes and bispectral index (BIS) values.

Methods: A total of 124 patients between the ages of 18-65 with ASA I-II undergoing general anesthesia for surgery were enrolled in the study. According to the sufentanil dose initially injected, they were randomly divided into groups P, S1, S2, and S3, with 31 cases in each group.

Complete Chloroplast Genome Sequence of , Insights into Comparative Chloroplast Genomics, Divergence Time Estimation and Phylogenetic Relationships among Dipsacales.

, ( L., Caprifoliaceae, Dipsacales) are widely distributed in China while mainly occurrs in northeast China. Few reports have been determined on the genus .

Pressure-induced Fermi resonance between fundamental modes in phthalic anhydride.

high-pressure Raman spectra of phthalic anhydride (PA) have been measured up to 16 GPa through diamond anvil cell technique. The results show that all the Raman bands are blue-shifted with the increase of pressure, accompanied by appearance of some new bands. A Fermi resonance phenomenon of the two Raman fundamental modes of PA at 773 cmand 801 cmis proposed at pressures above 6.

Dispersal into the Qinghai-Tibet plateau: evidence from the genetic structure and demography of the alpine plant .

Maxim., an alpine plant, is traditionally used for several medicinal purposes. Here, both chloroplast DNA sequences and nuclear low copy sequence markers were used to investigate the genetic diversity and population structure of .

Exosomal microRNA-19b targets FBXW7 to promote colorectal cancer stem cell stemness and induce resistance to radiotherapy.

Colorectal cancer (CRC) continues to be one of the most malignant cancers with a high mortality rate to date. Promoting the radio-responsiveness of CRC is of great importance for local control and prognosis. In this study, we examined the roles of exosomal microRNA-19b (miR-19b) in CRC radioresistance.

The complete chloroplast genome of (Caprifoliaceae), a perennial alpine herb.

is a perennial herb which is distributed in the eastern Himalayas, Hengduan Mountains, and central China. The complete chloroplast genome of is studied for the first time, which is 154,579 bp in length and is divided into four regions: two inverted repeat (IRA and IRB) regions of 23,370 bp, a small single copy (SSC) region of 18,682 bp and a large single copy (LSC) region of 89,157 bp. The plastid genome contains 133 genes, including 86 protein-coding genes, 39 tRNA genes, and 8 rRNA genes.

Westwards and northwards dispersal of (Caprifoliaceae) from the Hengduan Mountains region based on chloroplast DNA phylogeography.

The varying topography and environment that resulted from paleoorogeny and climate fluctuations of the Himalaya-Hengduan Mountains (HHM) areas had a considerable impact on the evolution of biota during the Quaternary. To understand the phylogeographic pattern and historical dynamics of (Caprifoliaceae), we sequenced three chloroplast DNA fragments (, , and ) from 238 individuals representing 20 populations. Nineteen haplotypes (H1-H19) were identified based on 23 single-site mutations and eight indels.

Gene Flow Results in High Genetic Similarity between (Rosaceae) Species in the Qinghai-Tibetan Plateau.

Studying closely related species and divergent populations provides insight into the process of speciation. Previous studies showed that the complex's evolutionary history on the Qinghai-Tibetan Plateau (QTP) was confusing and could not be distinguishable on the molecular level. In this study, the genetic structure and gene flow of and on the QTP was examined across 45 populations using 8 microsatellite loci.
