Metal ion-doped zero-dimensional halide perovskites provide good platforms to generate broadband emission and explore the fundamental dynamics of emission regulations. Recently, Sb-doped zero-dimensional halide perovskites have attracted considerable attention for the high quantum yield of yellow emission; however, the triplet state recombination is activated and the singlet state emission is usually absent. Herein, we fabricate an Sb-doped zero-dimensional [(CH)N]SnCl perovskite that can induce singlet and triplet emission.

The surface modification of the SiO cores with (3-mercaptopropyl)trimethoxysilane was found to be critical to generate a homogeneous coverage of ZnInS. The SiO@ZIS core-shell nanoparticles exhibited the best coverage but poor crystallinity when synthesized in pure ethanol, whereas best crystallinity but poor coverage was observed when synthesized in an aqueous solution.

Methods: This study includes singleton fetuses with the estimated fetal weight (EFW) using the formula of Hadlock C below the 10th percentile for gestational age. FGRs without structural anomalies were selected, and the ones at high risk of noninvasive prenatal testing for trisomy 13, 18 and 21 would be excluded.
Titanium dioxide (TiO) has gained increasing interest in materials research due to its outstanding properties and promising applications in a wide range of fields. From this perspective, we report the synthesis of custom-designed anatase TiO submicrometer particles coated with partial Au shells (ATiO-AuShl). The synthetic strategy used herein yields uniformly shaped monodisperse particles.

Methods: Human prostate cancer Du145 cells were injected into the subcutaneous layers on the back of nude mice. After a week, the mice bearing subcutaneous tumor graft were randomly divided into solanine treatment group and saline control group for treatment for 3 weeks.
Gold-silver nanoshells (GS-NSs) having a tunable surface plasmon resonance (SPR) were employed to facilitate charge separation of photoexcited carriers in the photocalytic production of hydrogen from water. Zinc indium sulfide (ZnIn2S4; ZIS), a visible-light-active photocatalyst, where the band gap varies with the [Zn]/[In] ratio, was used as a model ZIS system (E(g) = 2.25 eV) to investigate the mechanisms of plasmonic enhancement associated with the nanoshells.

Objective: To assess the value of fluorescence in situ hybridization (FISH) in the diagnosis of common chromosome number aberration in spontaneously aborted fetuses.
Method: A total of 100 spontaneously aborted fetuses were analyzed by G-banding and by FISH to test chromosome number aberration mainly for chromosomes 13, 18, 21, X and Y, and the results of FISH test was assessed according to those by G-banding test.
Results: FISH results were well consistent with those by G-banding test.

Objective: To investigate the value of real-time fluorescence quantitative PCR in the diagnosis of chromosome anepuploidy.
Methods: ABCC4 gene on chromosome 13, TYMS gene on chromosome 18, DSCR3 gene on chromosome 21, HPRT2 gene on chromosome X, and SRY gene on Y chromosome were used as the target genes, with GAPDH gene on chromosome 12 as the control gene. Using double-standard curve fluorescent relative quantitative PCR method with SYBR Green as the fluorescent dye, the gene expression levels were detected and the results were compared with those of karyotype analysis.

Objective: To investigate the value of fetal chromosomal karyotype analysis in cases of early spontaneous abortion.
Methods: Chorionic villus specimens obtained from 110 cases of early spontaneous abortion were cultured for karyotype analysis.
Results: Of the 110 cases, chorionic villus was successfully cultured in 103 cases (93.
