No full textTo provide a general overview of the microbial communities in environmentally conserved estuaries, the top 5 cm of sediment was sampled from the sandy estuary of the Shirakawa River and from the muddy estuary of the Midorikawa River. Higher amounts of organic matter were detected in the Midorikawa estuary sample than in the Shirakawa estuary sample. Measurement of redox potential revealed that the Shirakawa estuary was aerobic and the Midorikawa estuary was much less aerobic. Clone analysis was performed by targeting partial 16S rRNA gene sequences and using extracted DNA from the samples as a template. Various bacteria were detected, among which Gammaproteobacteria was dominant at both estuaries. Unclassified clones were detected in the Gammaproteobacteria group, mainly among samples from the Midorikawa estuary. Other detected bacterial groups were Alphaproteobacteria, Deltaproteobacteria, Chloroflexi, Actinobacteria, and Bacteroidetes. All the Deltaproteobacteria clones were anaerobic sulfate-reducing bacteria. Those aerobic and anaerobic bacteria coexisted in the top 5 cm of the estuary sediments indicating the surface layer have active sulfur and carbon cycle. Abundance of aerobic Gammaproteobacteria may be an indicator for conserved estuaries

No full textNeurotransmitter is released at synapses by fusion of synaptic vesicles with the plasma membrane. To sustain synaptic transmission, compensatory retrieval of membranes and vesicular proteins is essential. We combined capacitance measurements and pH-imaging via pH-sensitive vesicular protein marker (anti-synaptotagmin2-cypHer5E), and compared the retrieval kinetics of membranes and vesicular proteins at the calyx of Held synapse. Membrane and Syt2 were retrieved with a similar time course when slow endocytosis was elicited. When fast endocytosis was elicited, Syt2 was still retrieved together with the membrane, but endocytosed organelle re-acidification was slowed down, which provides strong evidence for two distinct endocytotic pathways. Strikingly, CaM inhibitors or the inhibition of the Ca2+-calmodulin-Munc13-1 signaling pathway only impaired the uptake of Syt2 while leaving membrane retrieval intact, indicating different recycling mechanisms for membranes and vesicle proteins. Our data identify a novel mechanism of stimulus-and Ca2+-dependent regulation of coordinated endocytosis of synaptic membranes and vesicle proteins
A comparative study of postoperative complications after hepatectomy in patients with and without chronic liver disease
No full textBACKGROUND:
Although hepatic resection is the most reliable treatment for hepatocellular carcinoma, impaired liver function because of cirrhosis or chronic hepatitis contributes to relatively high rates of postoperative complications. We have reviewed a series of hepatectomies at our institution and investigated risk factors for complications after hepatectomy in patients with impaired liver compared with patients with normal liver.
METHODS:
From October 1994 to March 1998, 277 hepatectomies for hepatocellular carcinoma, cholangiocellular carcinoma, metastatic liver tumors, and other hepatic diseases were performed. In an attempt to clarify the safety of hepatectomy for the impaired liver at our institution, we did a comparative study of postoperative complications after hepatectomy in 2 groups: patients with impaired livers (187 hepatectomies) and patients with normal livers (90 hepatectomies).
RESULTS:
Of the 277 hepatectomies, bile leakage occurred in 25 patients (16 in impaired livers vs 9 in normal livers), abdominal infection in 45 patients (30 vs 15 patients), wound infection in 13 patients (9 vs 4 patients), pleural effusion in 52 patients (35 vs 17 patients), atelectasis in 26 patients (17 vs 9 patients), pneumonia in 4 patients (3 vs 1 patients), ileus in 6 patients (3 vs 3 patients), intra-abdominal hemorrhage in 3 patients (0 vs 3 patients), and hyperbilirubinemia in 5 patients (4 vs 1 patients). Hepatic insufficiency and hospital death were not experienced in this series. The mean postoperative hospital stay was 22.9 days (23.5 vs 23.1 days), and except for intra-abdominal hemorrhage there was no statistically significant difference between the 2 groups.
CONCLUSIONS:
Hepatectomy for the impaired liver is now as safe a procedure as for the normal liver, provided the overall guidelines outlined in our algorithm are followed

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Inflammatory pseudotumors of the liver: prevalence and clinical impact in surgical patients
No full textProgress in diagnostic imaging has increased the number of focal liver lesions detected and reports of an occasional finding of inflammatory pseudotumors of the liver are becoming numerous. To estimate their prevalence and clinical impact in surgical series we evaluate retrospectively our experienc
Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
