The objective of the present study was to systematically assess the association between dioxin/2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and cancer incidence and mortality. Systematic literature searches were conducted until July 2015 in Pubmed, Embase and Cochrane library to identify relevant studies. A random-effects model was applied to estimate the pooled odds ratio (OR), risk ratio (RR), ...

Hydrocarbon exposure has been shown to play an important role in the development of renal dysfunction in several occupational settings. In this study, renal screening was performed in a group of paint sprayers with exposure to hydrocarbon-based paints, recruited from a car manufacturing plant where personal protective equipment was widely used. The hydrocarbon exposure scores and various marker...

Brevibacillus panacihumi strain W25 was isolated from hydrocarbon-contaminated saline soil. Here, we report the 5.5-Mb draft genome sequence of this strain, which may provide insights into the mechanism of microbial hydrocarbon degradation in saline environments.

Plastics are not easily biodegradable; and because of these characteristics they can remain under landfill and water for a very long period of time. All over the world only 6% of waste plastics are recycled and the rest of all waste plastics are dumped into landfills. An experiment was conducted in a laboratory scale batch process under Labconco’s fume hood utilizing low density polyethylene (L...

We investigated the effect of resveratrol, a constituent of the human diet that has been shown to inhibit aryl hydrocarbon-induced carcinogenesis in animals, on the carcinogen activation pathway regulated by the aryl hydrocarbon receptor. Resveratrol inhibited the metabolism of the environmental aryl hydrocarbon benzo[a]pyrene (B[a]P) catalyzed by microsomes isolated from B[a]P-treated human he...

Multi-variable predictive control (MVPC) can now be considered to be a mature technology with proven benefits, particularly in the Hydrocarbon Processing Industries. This paper outlines the current status of this technology and its typical applications. New directions are described, including multi-unit optimisation, the use of non-linear models in linear control, improved tools for inferential...

The glomerular sheet of the olfactory bulb (OB) forms odorant receptor maps that are parceled into zones. We previously reported the molecular receptive range (MRR) property of individual glomeruli in the dorsal zone (zone 1) of the OB and showed that polar functional groups play a major role in activating glomeruli in this zone. However, the MRR property of glomeruli in zones 2-4 is not well u...

The potential for biotransformation of weathered hydrocarbon residues in soils collected from two commercial oil refinery sites (Soil A and B) was studied in microcosm experiments. Soil A has previously been subjected to on-site bioremediation and it was believed that no further degradation was possible while soil B has not been subjected to any treatment. A number of amendment strategies inclu...

A kerosene type hydrocarbon fraction (equivalent to 7 L m(-2)) was added to enclosures in the surface layer of high-arctic intertidal beach sediment. The experimental spill was repeated in two consecutive years in the period July-September. The rate and extent of hydrocarbon removal and the accompanying bacterial response were monitored for 79 days (2002) and 78 days (2003). The bulk of added k...
