Bacterial community structure is influenced by vegetation, climate and soil chemical properties. To evaluate these influences, terminal restriction fragment length polymorphism (T-RFLP) and cloning of the 16S rRNA gene were used to analyze the soil bacterial communities in different ecosystems in southwestern China. We compared (1) broad-leaved forest,(More)
The effect of superparamagnetic iron oxide particles on magnetic resonance myocardial signal intensity was examined in order to define the ability of this agent to identify normal, ischemic, and reperfused myocardium. Data were obtained from 6 normal rats (group 1) and from 6 heterotopic isogenic rat heart transplants (group 2) at 4.7 T with a multislice(More)
MR contrast agents are used to improve the detectability of pathologic conditions. In this study we clarify the mechanism of action of a newly developed superparamagnetic agent (AMI-25, Advanced Magnetics Inc., Cambridge, MA). Transverse relaxation rates were measured from segments of rat brain, heart, and liver using a CPMG pulse sequence. Relaxation rates(More)
This study describes the effect of superparamagnetic iron oxide on myocardial signal intensity and defines the mechanism of action of this agent. Magnetic resonance images of the heart and relaxation data were obtained in 19 rats, and another three rats were used for measurements of contrast material concentration in the heart, with the contrast agent(More)
OBJECTIVE This prospective randomized study evaluated the efficacy and patient tolerance of dexmedetomidine compared with midazolam for sedation in postoperative patients undergoing flexible bronchoscopy. METHODS A total of 198 postoperative patients were randomized to receive dexmedetomidine (n=99) or midazolam (n=99) to produce conscious sedation for(More)
It has been reported that inactivation occurs before noticeable conformational change can be detected during denaturation of creatine kinase (ATP: creatine N-phosphotransferase, EC 2.7.3.2) and other enzymes by guanidinium chloride or urea. Therefore, Tsou suggested that enzyme active sites may display more conformational flexibility than the enzyme(More)
We investigated whether the administration of recombinant human interleukin-10 (rhIL-10) regulates the production of cytokine-induced neutrophil chemoattractant (CINC) and improves graft survival in rat orthotopic liver transplantation (OLTx). Allograft recipients received injections of rhIL-10 at doses of 2, 10, 20, or 50 micrograms/kg/day. The allograft(More)
OBJECTIVE The study was designed to evaluate the role of neuronal nitric oxide synthase (nNOS) and inducible nitric oxide synthase (iNOS) in ischemia-reperfusion injury (IRI) and acute rejection (AR) in rat intestinal transplantation, by administration of nitric oxide inhibitor N(G)-nitro-L-arginine methyl ester (LNAME). MATERIALS AND METHODS Rats that(More)
OBJECTIVE This study was designed to evaluate the role of nitric oxide (NO) in ischemia-reperfusion injury (IRI) and acute rejection (AR) in rat intestinal transplantation, using administration of the NO inhibitor N(G)-nitro-L-arginine methyl ester (L-NAME). MATERIALS AND METHODS Rats that underwent orthotopic allogeneic intestinal transplantation were(More)
