As a new category of persistent organic pollutants, polybrominated diphenyl ethers (PBDEs) have become ubiquitous global environmental contaminants. No literature is available on the aerobic biotransformation of decabromodiphenyl ether (BDE-209). Herein, we investigated the interaction of PBDEs with aerobic granular sludge. The results show that the removal of BDE-209 from wastewater is mainly ...

Simple model for anaerobic phosphorus release and aerobic uptake batch test was constructed based on ASM2d and analyzed with sensitivity analysis. And it was simulated with estimated parameters. The phosphorus behaviors were mainly influenced by the initial concentration of soluble COD (SA) in anaerobic condition and PHA (XPHA) in aerobic conditions, respectively. Sensitivity analysis suggested...

BACKGROUND This meta-analysis investigates the efficacy of exercise as a treatment for DSM-IV diagnosed anxiety disorders. METHODS We searched PubMED and PsycINFO for randomized, controlled trials comparing the anxiolytic effects of aerobic exercise to other treatment conditions for DSM-IV defined anxiety disorders. Seven trials were included in the final analysis, totaling 407 subjects. The ...

Two laboratory-scale sequencing batch reactors were used to study biological treatment of carbon and nitrogen in a new combined anaerobic-aerobic system. Piggery wastewater was used as a model effluent. The anaerobic reactor, fed with raw wastewater and nitrite/nitrate recycling from the aerobic reactor, carried out denitrification and anaerobic digestion of organic carbon. In the aerobic react...

A promoting effect of large bowel contents on colonic carcinogenesis as seen in the animal model is still incompletely explored in man. We investigated simultaneously deoxycholate absorption (as marker of colonic mucosal exposure to tumour promoting bile salt metabolites), mouth-anus transit time, and the ratio of anaerobic to aerobic bacteria in stool in 10 persons with colonic adenomas and in...

BACKGROUND Exposure to Air pollution PM10 results in lung inflammation increased risk of lung cancer. Regular aerobic exercise improves the inflammatory status in different lung diseases. However, the effects of long-term aerobic exercise on the pulmonary response to PM10 have not been investigated. OBJECTIVES The present study evaluated the effect of aerobic exercise on the lung inflammatory...

Aerobic granules are self-immobilized aggregates of microorganisms and represent a relatively new form of cell immobilization developed for biological wastewater treatment. In this study, both culture-based and culture-independent techniques were used to investigate the bacterial diversity and function in aerobic phenol- degrading granules cultivated in a sequencing batch reactor. Denaturing gr...

“Aerobic Interval Training Versus Continuous Moderate Exercise as a Treatment for the Metabolic Syndrome: A Pilot Study” To the Editor: We read with great interest the article by Tjønna et al1 that addressed the efficacy of different modes of exercise training to reverse features of the metabolic syndrome. The metabolic syndrome, considered an ailment of the 20th century, consists of a clusteri...
