Kinetics of Biphenyl and Polychlorinated Biphenyl Metabolism in Soil [PDF]

open access: yesApplied and Environmental Microbiology, 1985
The metabolism of 14 C-labeled PCBs (polychlorinated biphenyls), which comprised the Aroclor 1242 mixture, was greatly enhanced by the addition of biphenyl (BP) to soil. After 49 days, only 25 to 35% of the original PCBs remained in the soil, and 48 to 49% was converted to 14 CO 2

Environmental Exposures and Parkinson's Disease. [PDF]

open access: yes, 2016
Parkinson's disease (PD) affects millions around the world. The Braak hypothesis proposes that in PD a pathologic agent may penetrate the nervous system via the olfactory bulb, gut, or both and spreads throughout the nervous system. The agent is unknown,

Placental transfer of a hydroxylated polychlorinated biphenyl and effects on fetal and maternal thyroid hormone homeostasis in the rat [PDF]

open access: yes, 2002
Earlier studies at our laboratory indicated that several hydroxylated polychlorinated biphenyls (OH-PCBs) detected in human blood could specifically inhibit thyroxine (T4) transport by competitive binding to the thyroid hormone transport protein ...

Classical molecular dynamics investigations of biphenyl-based carbon nanomembranes

open access: yesBeilstein Journal of Nanotechnology, 2014
Background: Free-standing carbon nanomembranes (CNM) with molecular thickness and macroscopic size are fascinating objects both for fundamental reasons and for applications in nanotechnology. Although being made from simple and identical precursors their

Biphenyl-3,3′,4,4′-tetraamine [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2010
The title compound, C(12)H(14)N(4), has a crystallographically imposed centre of symmetry. Inter-molecular N-H⋯N hydrogen bonds between amino groups link adjacent mol-ecules into a three-dimensional network where ten-membered hydrogen-bonded rings are observed.

Serum concentrations of polybrominated biphenyls (PBBs), polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) in the Michigan PBB Registry 40 years after the PBB contamination incident

open access: yesEnvironment International, 2020
Widespread polybrominated biphenyls (PBBs) contamination occurred in Michigan from 1973 to 1974, when PBBs were accidentally substituted for a nutritional supplement in livestock feed. People who lived in the state were exposed to PBBs via several routes

Exposure to polychlorinated biphenyls and hexachlorobenzene, semen quality and testicular cancer risk [PDF]

open access: yes, 2015
PURPOSE: We carried out a case-control study to investigate the possible role of occupational and environmental exposure to endocrine disruptors in the onset of testicular cancer (TC). METHODS: We evaluated 125 TC patients and 103 controls.

Organochlorine pesticides accumulation and breast cancer: A hospital-based case–control study

open access: yesTumor Biology, 2017
The aim of this study is to detect the accumulation status of organochlorine pesticides in breast cancer patients and to explore the relationship between organochlorine pesticides contamination and breast cancer development. We conducted a hospital-based
