background and objectives: the development of molecular biological techniques provide a method for direct detection and identification of pathogens. this study attempted to compare bacterial culture and pcr to detect s. agalactiae in cattle milk samples. the pcr method was based on using primers v1 and v2 derived from the 16s rrna gene. materials and methods: one hundred milk samples were colle...

To elucidate the molecular mechanism by which the potent anticancer drug, 5-fluorouracil (5-FUra), inhibits cell proliferation, the effect of its metabolite, 5-fluorouridine triphosphate, on transcription of rat rRNA gene and processing of pre-rRNA was investigated in S-100 extract from the mouse lymphosarcoma cells. The in vitro processing of pre-rRNA substrate synthesized from the T3 promoter...

W represents a message. We will often consider that it is the output of the compressor. The encoder receives W and encodes it to X. The encoder puts X into the channel and Y n is the output the decoder receives. Finally, the decoder tries to estimate W through Y . The decoder’s estimate is denoted by Ŵ . Our goal is to understand what kind of encodings are such that Ŵ is the same as W with high...

Absrruct-This paper studies a speech coder using a tree code generated by a stochastic innovations tree and backward adaptive synthesis filters. The synthesis configuration uses a cascade of two all-pole filters: a pitch (long time delay) filter followed by a formant (short time delay) filter. Both filters are updated using backward adaptation. The formant predictor is updated using an adaptive...

Four yeast strains were isolated from soil in a mixed deciduous forest in Amphoe Wang Nam Khiao, Nakhon Ratchasima province, Thailand. On the basis of morphological, biochemical, physiological and chemotaxonomic characteristics, and the sequence analyses of the D1/D2 domain of the large-subunit (LSU) rRNA gene, small-subunit rRNA gene and internal transcribed spacer (ITS) region, the three stra...

We present the complete sequence of mouse 18 S rRNA. As indicated by comparison with yeast, Xenopus and rat, the conservation of eukaryotic 18 S rRNA sequences is extensive. However, this conservation is far from being uniform along the molecule: most of the base changes and the size differences between species are concentrated at specific locations. Two distinct classes of divergent traces can...
