The purpose of this study was to predict ONFH-induced collapse based on the percentage of the proximal sclerotic rim. In total, 101 patients satisfying the inclusion criteria who received treatment at Guang’anmen Hospital were enrolled. Bilateral hip-joint computed tomography (CT) of the necrotic tissue was performed, and the largest layer within the(More)
STUDY QUESTION Does in vitro fertilization (IVF) induce comprehensive and consistent changes in gene expression associated with mitochondrial biogenesis and function in mouse embryos from the pre- to post-implantation stage? SUMMARY ANSWER IVF-induced consistent mitochondrial dysfunction in early mouse embryos by altering the expression of a number of(More)
Small heat shock proteins (sHSPs) are a class of molecular chaperones that bind to and prevent aggregation of proteins. To assess the potential role of sHSPs in protection against abiotic stresses, we conducted a screening of sHSP genes from the desiccation-tolerant resurrection plant Boea hygrometrica, which is widespread in East Asia in alkaline,(More)
Along with the rapid development of the Internet, Web has become most importmant resource of information. It is getting more difficult to fast and accurately find useful information from the gigantic amount of data provided by Web. The Web usage mining is the process inferring valuable knowledge by analyzing users' access information, which is of great(More)
Although efficient transcervical transfer of embryos in mice would provide many advantages over a surgical method, the low success rate of transcervical transfer has hampered its acceptance and use. Here, we describe a novel device and protocol for transcervical embryo transfer in mice. Blastocysts from CD1 female mice were transferred into the uteri of(More)
A simple method of changing pre-treatment temperature in the course of film formation was used to tune the surface structures of PVA membranes. Surface structure and property of the resulting membranes were characterized by X-ray photoelectron spectroscopy (XPS), sum frequency generation (SFG) vibrational spectroscopy, and contact angle measurements. The(More)
Adverse environmental conditions cause endoplasmic reticulum (ER) stress in plants. To mitigate ER stress damage, ER associated transcription factors and inositol-requiring enzyme-1 (IRE1)-mediated bZIP60 mRNA splicing are activated in plants. A drought-induced gene, encoding the ortholog of AtbZIP60, was identified in the resurrection plant Boea(More)
OBJECTIVES To explore the effects of traditional Chinese medicine (TCM) constitutions on repair capacity after osteonecrosis of the femoral head (ONFH). DESIGN AND SETTING Ninety-six patients with TCM constitutions of yang-deficiency, dampness-heat and/or blood-stasis were recruited from the orthopedic outpatient clinic of the Guang'anmen Hospital of the(More)
The title compound, C(19)H(20)O(5), is approximately planar; the dihedral angle between the benzene rings is 3.82 (8)°, and the central propenone C(=O)-C=C plane makes dihedral angles of 1.95 (10) and 3.17 (11)° with the two benzene rings. In the crystal structure, intra- and inter-molecular C-H⋯O hydrogen bonds are observed.
A mesophilic, Gram-negative, arsenite[As(III)]-oxidizing and arsenate[As(V)]-reducing bacterial strain, Pseudomonas sp. HN-2, was isolated from an As-contaminated soil. Phylogenetic analysis based on 16S rRNA gene sequencing indicated that the strain was closely related to Pseudomonas stutzeri. Under aerobic conditions, this strain oxidized 92.0%(More)
