The effect of sludge retention time (SRT) on biomass, kinetic parameters, and stoichiometric parameters of ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB) in anaerobic/anoxic/oxic (A(2)O) process were explored in this study. The results showed that the growth rate constants were 1.52, 1.22, and 0.85 day(-1), respectively, for AOB, those were 1.59, 1.19, and 0.87 day(-1), r...
Gastric cancer (GC) is the fourth most common malignant tumor worldwide and the second highest in developing countries (Jemal et al., 2010; Parkin, 2001; Siegel et al., 2012). It also ranks as the second leading cause of cancer death worldwide (Camargo et al., 2012; Yin et al., 2012). Moreover, nearly 47% of worldwide gastric cancer cases occur in China alone (Shen et al., 2013b). Currently rad...
Agents capable of inducing phase II enzymes such as quinone reductase 1 (QR1) are known to have the potential of mediating cancer chemopreventive activity. As part of a program to discover novel phase II enzyme-inducing molecules, we identified a marine-derived actinomycete strain (CNJ-878) that exhibited activity with cultured Hepa 1c1c7 cells. Based on this activity, a new macrolide, juvenimi...
