BACKGROUND The human endogenous retroviral family W, Env(C7), member 1 gene (HERVWE1) is thought to participate in trophoblast cell fusion, and its expression is diminished in the placentas of singleton intrauterine growth-retarded pregnancies. However, there is limited information about the role of HERVWE1 in discordant fetal growth in twins. This study(More)
It is important to develop functional transmucosal implant surfaces that reduce the number of initially adhering bacteria and they need to be modified to improve the anti-bacterial performance. Commercially pure Ti sheets were anodized in an electrolyte containing ethylene glycol, distilled water and ammonium fluoride at room temperature to produce TiO2(More)
Recombinant β-glucosidase-expressing strains were constructed by integrating different copies of the BGL1 gene from Saccharomycopsis fibuligera into the chromosome of an industrial ethanol-producing strain of Saccharomyces cerevisiae. The engineered strains were evaluated for ethanol fermentation using cellobiose as sole carbon source. The results showed(More)
Intrauterine growth restriction (IUGR) affects the foetus and has a number of pathological consequences throughout life. Recent work has indicated that variations in DNA methylation might cause placental dysfunction, which may be associated with adverse pregnancy complications. Here, we investigated the promoter methylomes of placental shares from seven(More)
DNA methylation plays a critical role in the regulation of gene expression, genomic DNA stability, cell proliferation, and malignant transformation. Common cellular features including fast tissue expansion, invasive growth, and active angiogenesis, have been noticed between placental development and tumorigenesis by many investigators. While the DNA(More)
Mixed-phase TiO2 nanocomposite thin films consisting of anatase and rutile prepared on commercially pure Ti sheets via the electrochemical anodization and annealing treatments were investigated in terms of their photocatalytic activity for antibacterial use around dental implants. The resulting films were characterized by scanning electron microscopy (SEM),(More)
