Defects in migration and invasion caused by dysregulation of trophoblast epithelial-mesenchymal transformation (EMT) are one of the key factors in the pathogenesis of preeclampsia (PE). RNA-binding motif protein 25 (RBM25) is an RNA-binding protein involved in a variety of cellular processes, including cell proliferation, apoptosis, cell migration and invasion, and EMT. However, the expression and function of RBM25 in placental of PE remain unclear.

It was found that L/DG-Cm self-assembled into short nanotubes in toluene, while it formed longer nanotubes together with an obvious helix nanobelt structure for L/DG-Cm in DMSO, demonstrating that the nanotubes were formed by nanobelt rolling. The CD and CPL spectra revealed the same chiral property of the L/DG-Cm assemblies formed in toluene and DMSO.

Ordered mesoporous TiO materials are successfully synthesized via a sol-gel route using butyl titanate as a precursor and sodium dodecyl benzene sulfonate surfactants as soft templates. The as-prepared TiO samples possess a relatively high surface area of 40.03 m/g and the center of pore diameter distribution of 13.

Objective: To screen for mutations of deafness-related genes among ethic Chinese women of child-bearing age.
Methods: In 324 women, 9 mutational sites in 4 deafness-related genes (SLC26A4, GJB3, GJB2 and mtDNA 12s rRNA) were screened using a gene chip.
Results: Twenty women (6.
Hearing loss is the most common sensory disorder, and at least 50% of cases are due to a genetic etiology. Two-thirds of individuals with congenital deafness are nonsyndromic. Among the nonsyndromic forms, the large majority are monogenic autosomal recessive traits.

Comparative sonocatalytic degradation experiments were carried out in different conditions under ultrasonic irradiation by using rhodamine B (RhB) as the model substrate, indicating that Sr(OH)2·8H2O was highly sonocatalytic. Total organic carbon experiment demonstrated Sr(OH)2·8H2O with mass mineralization of organic carbon.

Background And Aim: The FAS and FASL system play an important role in regulating apoptotic cell death. This study was designed to investigate the correlation of FAS-1377 G/A, -670 A/G and FASL-844 T/C polymorphisms with susceptibility to gastric cardiac adenocarcinoma in a population of a high-incidence region of Hebei Province.
Methods: FAS-1377 G/A, -670 A/G and FASL-844 T/C polymorphisms were genotyped by polymerase chain reaction-restriction fragment length polymorphism analysis in 262 gastric cardiac carcinoma (GCA) patients and 524 healthy controls.

Objective: To investigate the effect of CDH1 3'-UTR + 54C/T single nucleotide polymorphism (SNP) on expression of luciferase reporter gene and its association with susceptibility to cervical cancer.
Methods: The luciferase gene expression vectors containing CDH1 3'-UTR+54C/T SNP C or T allelotype were constructed. The effect of CDH1 3'-UTR+54C/T SNP on expression of luciferase reporter gene in 293 T cells were tested by daul luciferase reporter assay system.
The aim of the present study was to investigate the association of single nucleotide polymorphisms (SNPs) in matrix metalloproteinase (MMPs) with the risk of gastric cardia adenocarcinoma (GCA) and esophageal squamous cell carcinoma (ESCC). Genotypes were analyzed by polymerase chain reaction-restriction fragment-length polymorphism method in 592 patients and 624 healthy individuals. Significant differences in allele and genotype distributions of MMP-2 -1306C --> T SNP were observed between ESCC and controls (P = 0.
