In vitro effects of the organochlorine pesticide β-hexachlorocyclohexane on bovine peripheral blood mononuclear cells

Italian Journal of Animal Science, 2014
The β-hexachlorocyclohexane (β-HCH) is a very stable and accumulable isomer of Lindane, a well known organochlorine pesticide. The HCHs were banned in all developed countries but to date high concern still exists for environment, animal and human health ...

Bioremediation of halogenated compounds: comparison of dehalogenating bacteria and improvement of catalyst stability [PDF]

, 2006
Five bacterial strains were compared for halogenated compounds conversion in aqueous media. Depending on the strain, the optimal temperature for dehalogenase activity of resting cells varied from 30 to 45 degrees C, while optimal pH raised from 8.4 to 9 ...

GENETICS AND BIOCHEMISTRY OF DEHALOGENATING ENZYMES [PDF]

, 1994
Microorganisms that can utilize halogenated compounds as a growth substrate generally produce enzymes whose function is carbon-halogen bond cleavage. Based on substrate range, reaction type and gene sequences, the dehalogenating enzymes can be classified

Persistent β-Hexachlorocyclohexane Exposure Impacts Cellular Metabolism with a Specific Signature in Normal Human Melanocytes

Cells
Background: Cutaneous melanoma arises from skin melanocytes and has a high risk of metastatic spread. Despite better prevention, earlier detection, and the development of innovative therapies, melanoma incidence and mortality increase annually.
