“Biological treatment of simulated tannic acid (TA)-containing wastewater by activated sludge was investigated to find the optimal biodegradation conditions and investigate the aerobic biodegradation kinetics. Activated sludge was acclimatized to simulated wastewater with TA concentration up to 950 mg/l Ulixertinib over a period of 27 days. Batch experiments on TA biodegradation under different pH, temperature, aeration conditions and with different initial substrate concentrations were conducted. The initial biomass concentration was kept at 2000mg/l. By comparing the degradation rates under different conditions, the optimal ranges of pH, temperature

and DO for TA biodegradation in the activated sludge system were determined: pH approximate to 7. temperature = 20-35 degrees C, DO > 1.0 mg/l. A biodegradation kinetic model that takes into consideration substrate inhibition and endogenous decay was established, and its kinetic parameters were determined. The estimated values of mu(max), K(s), K(i), k(d) and Y were 0.208 h(-1), 226 mg/l, 522 mg/l, 0.0092 h(-1) and 0.594, respectively. (C) 2008 Elsevier B.V. All rights reserved”
“Porcine circovirus type 2 (PCV2) is the major causative agent of postweaning multisystemic wasting syndrome (PMWS) in Taiwanese pig farms. We analyzed the complete genomes of 571 Taiwanese PCV2 isolates in Taiwan from 2001 to 2011 and divided the isolates into 2 distinct genotypes (PCV2a and PCV2b) with 6 clusters (1A, OICR-9429 solubility dmso 1B, 1C, 2B, 2D, and 2E). Of the 571 Taiwanese PC)12 isolates, 22.9% (131/571) belonged to PCV2a and 77.1% Histone Methyltransf inhibitor (440/571) to PCV2b. In this study, PCV2a isolates were the most common in 2001, and then PCV2b isolates became predominate thereafter and widely distributed

in pig farms since 2003. Sequence comparisons among the 571 isolates indicated that 89.6-100% had nucleotide identity for complete genome and 87.3-100% for open reading frames 2 (ORF2). The results suggest that a higher genetic variation and shift occurred among PCV2 isolates collected from 2001 to 2011 in Taiwan. Crown Copyright (C) 2012 Published by Elsevier Ltd.

“Introduction: Assessment of ventricular activation pattern is critical to the successful ablation of ventricular tachycardia (VT). We have previously shown that the global atrial activation pattern during tachycardia can be rapidly and accurately assessed by calculating the postpacing interval variability (PPIV); PPIV was minimal in circuitous tachycardias and highly variable in centrifugal tachycardias. In the present study, we use the PPIV to determine the ventricular global activation pattern during VT.

Methods: Patients with mappable VT were included.
