We present analysis and photoionization modeling of the Chandra high resolution spectrum of Mrk 279. There is clear evidence of an absorbing outflow which is best fit by a two component model, one with a low ionization parameter and one with a higher ionization parameter. The column density of the X-ray warm absorber, about logNH = 20, is the smallest known of all AGNs in which X-ray absorbing ...
Differentiated embryo-chondrocyte expressed gene 1 (DEC1, also known as sharp2, stra13, or BHLHB2) is a mammalian basic helix-loop-helix protein that is involved in many aspects of gene regulation through acting as a transcription factor. Changes in DEC1 expression levels have been implicated in the development of cancers. Using COS-7 cell, we showed that DEC1 can be modified by the small ubiqu...
More and more studies have focused on microRNAs (miRNAs) expression in the pest Helicoverpa armigera (Lepidoptera: Noctuidae) recently. Quantitative real-time PCR (qRT-PCR) is being widely used in miRNA expression studies. Suitable reference genes are necessary for the correct analysis of results. In this study, 10 candidate genes of H. armigera were selected and analyzed for their expression s...
The epitopes of human thyroid-stimulating hormone (hTSH) recognized by two murine monoclonal antibodies (MAbs), designated MAb 279 and MAb 299, have been characterized. These MAbs are highly specific for the beta-subunit of TSH. The epitope recognized by MAb 279 appears to be completely conserved between bovine and human TSH and partially conserved in the porcine species. The TSH beta-subunit e...
We present a new technique for directly measuring the distances to superluminal radio sources. By comparing the observed proper motions of components in a parsec scale radio jet to their measured Doppler factors, we can deduce the distance to the radio source independent of the standard rungs in the cosmological distance ladder. This technique requires that the jet angle to the line of sight an...
