OBJECTIVE Our purpose was to determine whether breast milk lead (Pb) levels are correlated with maternal blood Pb levels, bone loss, or bone turnover during reproduction. STUDY DESIGN Data were collected prospectively at 0, 1.5, 3, 6, and 12 months after delivery in 15 lactating and 30 bottle-feeding women. Variables included breast milk Pb (inductively(More)
ClC-3 is a voltage-gated Cl- channel that is highly conserved and widely expressed, although its function, localization, and properties remain a matter of considerable debate. In this study, we have shown that heterologous expression of ClC-3 in either Chinese hamster ovary (CHO-K1) or human hepatoma (Huh-7) cells results in the formation of large, acidic(More)
miRNAs are small 19 to 22 nucleotide sequences of RNA that negatively regulate gene expression. miRNA expression profiles may become useful biomarkers for diagnostics, prognosis and prediction of response to treat, and it could be a powerful tool for cancer prevention and therapeutics. Several miRNA expression profiles of(More)
Semaphorins and plexins are implicated in the progression of various types of cancer, although the molecular basis has not been fully elucidated. Here, we report the expression of plexin-B3 in glioma cells, which upon stimulation by its ligand Sema5A results in significant inhibition of cell migration and invasion. A search for the underlying mechanism(More)
Hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) is a rapidly progressing and frequently fatal condition. The aim of this study was to determine whether interleukin- (IL-) 33 and soluble ST2 (sST2) were associated with disease severity and mortality in HBV-ACLF. We found that plasma levels of sST2 but not IL-33 were higher in HBV-ACLF(More)
TGFβ1 is very important in the synthesis and degradation of extracellular matrix, and also in the mediation of human lung fibroblasts proliferation, and miR-29 plays an important role in this process. To explore the interactions of miR-29 family members and TGFβ1, the effects of transforming growth factor TGFβ1 on the expression of miR-29 and whether miR-29(More)
This study aims to compare the advantages and disadvantage of percutaneous endoscopic lumbar discectomy (PELD) and standard discectomy (SD) for the treatment of lumbar intervertebral disc herniation (LDH). We searched in MEDLINE, EMBASE, PubMed, Web of Science and Cochrane databases for relevant trials that compare PELD and SD for the treatment of LDH. The(More)
OBJECTIVE To explore the relationship between posttraumatic stress disorder (PTSD) in flood victim parents and children in Hunan, China. METHODS Using the method of multistage cluster random sampling, we conducted a retrospective investigation on 3,698 families in Hunan, China who suffered from flooding in 1998. Investigators held face-to-face interviews(More)
OBJECTIVE To construct a life-sized eye model using the three-dimensional (3D) printing technology for fundus viewing study of the viewing system. METHODS We devised our schematic model eye based on Navarro's eye and redesigned some parameters because of the change of the corneal material and the implantation of intraocular lenses (IOLs). Optical(More)
Hepatocytes possess chloride channels at the plasma membrane and in multiple intracellular compartments. These channels are required for cell volume regulation and acidification of intracellular organelles. Evidence also supports a role of chloride channels in modulation of apoptosis and cell growth. Swelling- and Ca(2+)-activated chloride channels have(More)
