This study applied Illumina high-throughput sequencing to explore the microbial communities and functions in anaerobic digestion sludge (ADS) from two wastewater treatment plants based on a metagenomic view. Taxonomic analysis using SILVA SSU database indicated that Proteobacteria (9.52–13.50 %), Bacteroidetes (7.18 %–10.65 %) and Firmicutes (7.53 %–9.46 %)(More)
Seven ACE inhibitors were studied for possible differences in distribution to aorta, brain, heart, lung, and kidney after administration of single oral doses to spontaneously hypertensive rats (SHR). Doses, normalized for differences in inhibitory potency and molecular weight, were expected to deliver equivalent levels of ACE-inhibitory activity to the(More)
We determined the relationship between cardiac angiotensin-converting enzyme (ACE) inhibition and anti-ischemic efficacy of several structurally different ACE inhibitors or their prodrug esters perfused through the isolated rat heart. Seven ACE inhibitors inhibited cardiac ACE to varying degrees due to differences in uptake during perfusion through(More)
1. Seven drugs (captopril, zofenopril, enalapril, ramipril, lisinopril, fosinopril, and SQ 29,852) were compared in vitro in homogenates of aorta, brain, heart, lung, and kidney and in sera of spontaneously hypertensive rats (SHR) both with respect to potencies of their active moieties as inhibitors of angiotensin-converting enzyme (ACE), and, where(More)
Sewage discharge could be a major source of polycyclic aromatic hydrocarbons (PAHs) in the coastal waters. Stonecutters Island and Shatin Sewage Treatment Works (SCISTW and STSTW) in Hong Kong, adopted chemically enhanced primary treatment and biological treatment, respectively. This study aimed at (1) determining the removal efficiencies of PAHs, (2)(More)
The effectiveness and treatment conditions of FeCl3- and AlCl3-coagulated municipal sewage sludge from chemically enhanced primary treatment (CEPT) using anaerobic digestion (AD) and the structure of microbial community were investigated. The results based on 297 measurements under different operational conditions demonstrate good average AD performance of(More)
Anterior knee laxity of 100 Chinese male subjects who had no history of previous injuries to their knees was examined with an instrumented knee arthrometer (MEDmetric Knee Arthrometer, model KT-1000). Two measurements were used to evaluate the anterior laxity: 1) anterior displacement produced by anterior force of 89 newtons (20 lbs); and 2) anterior(More)
Conventional membrane bioreactor (MBR) systems have increasingly been studied in recent decades. However, their applications have been limited due to their drawbacks such as low flux, membrane fouling, and high operating cost. In this study, a compact macro-filtration MBR (MfMBR) process was developed by using a large pore size membrane to mitigate the(More)
This study was to investigate removal efficiencies and profiles of 14 polybrominated diphenyl ether (PBDE) congeners by two different types of sewage treatment work (STW) in Hong Kong: Stonecutters Island STW (SCISTW) which uses chemically enhanced primary treatment (CEPT) process and Sha Tin STW (STSTW) which adopts biological treatment. The results(More)
