The newly isolated Pseudomonas sp. ZUTSKD was evaluated for its ability to degrade nicotine in tobacco waste extract (TWE). The strain degraded nicotine completely when the concentration of reducing sugar in TWE was lower than 8 gL(-1). Yeast extract and phosphate additions improved nicotine degradation in 5% TWE. At 30 degrees C and pH 7.0, with additional(More)
Reconstituted tobacco sheet process has been developed to treat and reuse tobacco wastes in the industry. During this process, microorganisms in original and concentrated tobacco waste extract (TWE) might play important roles in the final quality of the reconstituted tobacco. However, microbial communities in TWE remain largely unknown. In the present(More)
We describe a novel functional imaging approach for quantitative analysis of right ventricular (RV) blood flow patterns in specific experimental animals (or humans) using real-time, three-dimensional (3-D) echocardiography (RT3D). The method is independent of the digital imaging modality used. It comprises three parts. First, a semiautomated segmentation(More)
Functional imaging computational fluid dynamics simulations of right ventricular (RV) inflow fields were obtained by comprehensive software using individual animal-specific dynamic imaging data input from three-dimensional (3-D) real-time echocardiography (RT3D) on a CRAY T-90 supercomputer. Chronically instrumented, lightly sedated awake dogs (n = 7) with(More)
Intraventricular diastolic right ventricular (RV) flow field dynamics were studied by functional imaging using three-dimensional (3D) real-time echocardiography with sonomicrometry and computational fluid dynamics in seven awake dogs at control with normal wall motion (NWM) and RV volume overload with diastolic paradoxical septal motion. Burgeoning flow(More)
Nicotine is a key harmful component of tobacco and cigarettes, and the development of low-nicotine cigarettes is of increasing importance in the market. The objectives of this study are to isolate native nicotine-degrading strains and evaluate their feasibility for nicotine reduction during the aging (or fermentation) of tobacco leaves. A novel(More)
OBJECTIVE Limitations in clinical understanding of right ventricular relaxation can be attributed to the paucity of information from basic studies in animal models of right ventricular disease. This study examined, in the conscious state, right ventricular relaxation dynamics under normal conditions (n = 15) and in subacute (2-5 weeks) canine models of(More)
Tanshinone IIA is extracted from the root of Salvia miltiorrhiza and used in traditional Chinese medicine for its anti-inflammatory activity and antioxidant effects. The aim of the present study was to investigate the potential protective effects of tanshinone IIA against fibrosis in a rat model of cirrhosis and to elucidate the underlying mechanisms. Male(More)
By limiting filling, abnormalities of right ventricular (RV) diastolic function may impair systolic function and affect adaptation to disease. To quantify diastolic RV pressure-volume relations and myocardial compliance (MC), a new sigmoidal model was developed. RV micromanometric and sonomicrometric data in alert dogs at control (n = 16) and under(More)
PURPOSE To increase opportunities for advanced clinical training, a few medical schools in China have created U.S.-style, temporary-contract residency programs for medical graduates, but nearly nothing is known about what proportion of residents successfully complete these programs or what factors affect attrition. METHOD By directly surveying and(More)
