Human health and chemical mixtures: an overview
Autor: Kathleen F. Arcaro, William D. Niemi, Dilip D. Vakharia, S Pang, David O. Carpenter, Brian Bush
Publikováno v: Environmental Health Perspectives
Unlike laboratory animals, people are rarely exposed to a single hazardous chemical. However, most of the information documenting adverse human health effects from environmental and occupational contaminants has come from studies focused on exposure

PCBs reduce long-term potentiation in the CA1 region of rat hippocampus
Autor: David O. Carpenter, Jennifer Audi, William D. Niemi, Brian Bush
Publikováno v: Experimental neurology. 151(1)
Prenatal exposure to polychlorinated biphenyls (PCBs) has been associated with a lower IQ in childhood. We have examined the effects of acute exposure to PCB mixtures and two single congeners on synaptic transmission between Schaffer collaterals and

Propylthiouracil treatment reduces long-term potentiation in area CA1 of neonatal rat hippocampus
Autor: David O. Carpenter, Robert Rej, Kelly Slivinski, William D. Niemi, Jennifer Audi
Publikováno v: Neuroscience letters. 210(2)
Rat pups were made hypothyroid by exposure to propylthiouracil in drinking water beginning at 1 week of age, and the degree of long-term potentiation (LTP) in hippocampal area CA1 determined from brain slices of animals ranging in age from 2 to 6 wee

DDT and sodium transport in the eel electroplaque
Autor: William D. Niemi, George D. Webb
Publikováno v: Pesticide Biochemistry and Physiology. 14:170-177
DDT inhibits the ATPase activity of the intact eel electroplaque. At a concentration of 10 −5 M , DDT inhibited 46% of the total ATPase activity, and 10 −4 M DDT inhibited 62% of the total ATPase activity and 62% of the ouabain-sensitive ATPase a

Veratridine enhancement of agonist-induced synaptic membrane depolarization in electroplax
Autor: Terrone L. Rosenberry, William D. Niemi
Publikováno v: Life sciences. 19(5)
Veratridine in low concentrations (20 μ M ) and at high pH (pH 9) acts as a synergist for carbamylcholine-induced depolarizations in the electroplax of electric eel. This potentiation is not sensitive to tetrodotoxin, but is significantly reduced by

Studies of the blood chemistry of Electrophorus electricus and a new physiological saline solution based thereon
Autor: George D. Webb, Burt B. Hamrell, William D. Niemi, Donald A. Farquharson
Publikováno v: Biochimica et biophysica acta. 297(2)
Based upon analyses of the composition of electric eel blood serum we suggest a new physiological saline solution as follows: 188 mM NaCl, 5 mM KCl, 2 mM MgCl 2 , 2 mM CaCl 2 , 0.15 mM NaH 2 PO 4 , 1.45 mM Na 2 HPO 4 and 5 mM glucose; pH 7.4. The maj
