Twenty years has passed since the first discovery of microRNA (miRNA) lin-4 in Caenorhabditis elegans. Over the last decade, the study of miRNA biology has attracted tremendous attention. Increasing evidence has demonstrated that miRNA dysregulation could lead to a large number of genetic diseases and miRNA expressions are closely associated with the pathogenesis of most human malignancies. Recent...
Hollandite-type MnO 2 (HMDO) with hydronium as tunnel counter ion was synthesized by oxidation of MnSO 4 with ozone in a concentrated sulfuric acid solution.Its composition and structure were analyzed and characterized by inductive coupled plasma atomic emission spectrometry (ICP-AES), titration, Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and scanning...
