Small, regulatory, non-coding RNA (ncRNA) is involved in various cell functions in both prokaryotes and eukaryotes. However, information on ncRNA in cyanobacteria is still scarce. We studied ncRNA genes by computational screening to compare the intergenic regions of the Synechococcus elongatus PCC 6301 genome with the genomes of three freshwater(More)
Previous studies have reported that the signal attenuation of diffusion weighted magnetic resonance imaging for tumor tissues displays a non-monoexponential biexponential decay, and the apparent diffusion coefficients (ADCs) can be divided into a fast and slow diffusion component by using a simple biexponential decay model. The purpose of this study is to(More)
BACKGROUND Previous studies have reported that the signal attenuation of diffusion-weighted magnetic resonance imaging (DWI) for normal breast tissue and tumor were well fitted by a monoexponential and a biexponential function, respectively. The aim of this study was to investigate the optimal b-value to detect breast tumors from DWI signal attenuations. (More)
