BACKGROUND Prostate cancer is characterized by heterogeneity in the clinical course that often does not correlate with morphologic features of the tumor. Metastasis reflects the most adverse outcome of prostate cancer, and to date there are no reliable morphologic features or serum biomarkers that can reliably predict which patients are at higher risk of(More)
We analyze online gaming as a site of collaboration in a digital-physical hybrid. We ground our analysis in findings from an ethnographic study of the online game World of Warcraft in China. We examine the interplay of collaborative practices across the physical environment of China's Internet cafes and the virtual game space of World of Warcraft. Our(More)
The effect of different amplification and labeling methods on DNA microarray expression results has not been previously delineated. To analyze the variation associated with widely accepted T7-based RNA amplificationand labeling methods, aliquots of the Stratagene Human Universal Reference RNA were labeled using three eukaryotic target preparation methods(More)
OBJECTIVE Lack of physical activity (PA) is common in patients with chronic insomnia. Studies to increase PA and decrease sedentary behavior in those patients are limited. Therefore, we investigated the efficacy of "PA counseling combined with sleep restriction (SR) therapy (PASR)" vs only SR in the patients with chronic insomnia. METHODS Seventy-one(More)
—Change detection techniques are widely used in environmental monitoring, however, the issue of best suitability of change detection techniques for a specific application, even study area is still unanswered. In case of reconstruction monitoring, difference-based change detection methods are compared and evaluated in detecting changes on the study area(More)

METHODS One hundred and sixty eighty patients with primary insomnia as research group and 149 healthy people as control group were recruited during November 2013 to December 2014 in the psychiatry department of the Third Affiliated Hospital, Sun(More)
S-adenosylhomocysteine/Methylthioadenosine nucleosidase (SAHN E.C. does not exist in mammalian cells but is essential for methyl recycling in numerous bacterial and protozoan species. Inhibition of this enzyme could limit synthesis of autoinducers of bacterial quorum sensing (QS), and hence, causes reduction in biofilm formation and may attenuate(More)
