Reference genes (RG) as sample internal controls for gene transcript level analyses by quantitative RT-PCR (RT-qPCR) must be stably expressed within the experimental range. A variety of in vitro cell culture settings with primary human hepatocytes, and Huh-7 and HepG2 cell lines, were used to determine candidate RG expression stability in RT-qPCR analyses. Employing GeNorm, BestKeeper and Normf...

Among 13 patients with recurrent colorectal cancer (recurrence group: RG), immunohistochemical expression of Topo-1 was high in 4 patients (30.8%) and low in 9 patients (69.2%), while the non-recurrence group (N-RG) (n=8) showed high expression in 1 patient (12.5%) and low expression in 7 patients (87.5%) (NS). Regarding immunohistochemical expression of Bax/ERCC-1, high Bax/low ERCC-1 expressi...

N-methylpyrrole-RG (RG = Ar, Kr) complexes are investigated using resonance-enhanced multiphoton ionization (REMPI) and zero-electron-kinetic-energy (ZEKE) spectroscopy. The RG atom makes the electronic transition to S1 state allowed, REMPI spectrum is blue-shifted compared N-methylpyrrole origin, with no bands associated vibrational excitation of moiety. nature structure discussed. Binding ene...

OBJECTIVES Deep-inspiration breath-hold (DIBH) PET/CT with short-time acquisition and respiratory-gated (RG) PET/CT are performed for pulmonary lesions to reduce the respiratory motion artifacts, and to obtain more accurate standardized uptake value (SUV). DIBH PET/CT demonstrates significant advantages in terms of rapid examination, good quality of CT images and low radiation exposure. On the ...

Hematopoietic progenitor cell levels were monitored in the peripheral blood and bone marrow of 30 cancer patients receiving recombinant human granulocyte-colony stimulating-factor (rG-CSF) in a phase I/II clinical trial. The absolute number of circulating progenitor cells of granulocyte-macrophage, erythroid, and megakaryocyte lineages showed a dose-related increase up to 100-fold after four da...

To investigate the extent to which the proportion of schizophrenia's additive genetic variation tagged by SNPs is shared by populations of European and African descent, we analyzed the largest combined African descent (AD [n = 2,142]) and European descent (ED [n = 4,990]) schizophrenia case-control genome-wide association study (GWAS) data set available, the Molecular Genetics of Schizophrenia ...

The major neural stem cell population in the developing cerebral cortex is composed of the radial glial cells, which generate glial cells and neurons. The mechanisms that modulate the maintenance of the radial glia (RG) stem cell phenotype, or its differentiation, are not yet completely understood. We previously demonstrated that the transforming growth factor-β1 (TGF-β1) promotes RG differenti...

We have engineered polymers called ReGeneraTing Agents (RGTAs), which mimic the protecting and potentiating properties of heparan sulfates toward heparin-binding growth factors (HBGF). RGTAs have been shown to optimize cell growth and regulate collagen production in vitro. Here, we studied relationships between RGTA structure and collagen-type expression in aortic smooth muscle cells by using t...

5 of 49 topics: with r g~5:8 km, br5 1.656 0.15 and k5 350km (Fig. 1d, see Supplementary Information for statistical validation). Lévy flights are characterized by a high degree of intrinsic heterogeneity, raising the possibility that equation (2) could emerge from an ensemble of identical agents, each following a Lévy trajectory. Th refore, we determined P(rg) for an ensemble of agents followi...
