noted for in vivo exposures in developing rats. Surprisingly, the effects of diazinon, dieldrin and Ni(2+) showed basic similarities despite the fact that all three come from different classes of toxicants. Our findings provide some of the first evidence for a specific mechanistic cascade contributing to the cholinesterase-independent developmental neurotoxicant actions of chlorpyrifos and its differences from diazinon, while at the same time identifying mechanistic convergence between otherwise unrelated toxicants that provides predictions about common neurodevelopmental outcomes. These results further show how combined use of cell cultures and microarray technology can guide future in vivo work on diverse developmental neurotoxicants.

Abstract: Abstract: Unrelated developmental neurotoxicants can produce similar neurobehavioral outcomes. We examined whether disparate agents affect neuromodulators that control numerous neurotransmitters and circuits, employing PC12 cells to explore the targeting of neuroactive peptides by organophosphates (chlorpyrifos, diazinon), an organochlorine (dieldrin) and a metal (Ni2+); we utilized microarrays to profile gene expression for the peptides and their receptors. Chlorpyrifos evoked robust upregulation of cholecystokinin, corticotropin releasing hormone, galanin, neuropeptide Y, neurotensin, preproenkephalin and tachykinin 1; this involved a critical period at the commencement of neurodifferentiation, since the effects were much less notable in undifferentiated PC12 cells. Diazinon targeted a similar but smaller repertoire of neuropeptide genes and the magnitude of the effects was also generally less. Surprisingly, dieldrin shared many of the same neuropeptide targets as the organophosphates and concordance analysis showed significant overlap among all three pesticides. However, dieldrin had more notable effects on neuropeptide receptors, and overlap between diazinon and dieldrin for the receptors led to a stronger resemblance of these two agents than of chlorpyrifos and dieldrin. Ni2+ was unique, evoking upregulation of only one of the peptides affected by the other agents, while causing downregulation of several others. Nevertheless, there was still significant concordance between Ni2+ and either diazinon or dieldrin, reflecting similarities toward the receptors. Our results show that neuropeptides are likely to be a prominent target for the developmental neurotoxicity of organophosphates and other neurotoxicants, and further, that the convergence of disparate agents on the same genes and pathways may contribute to similar neurobehavioral outcomes.

1272. ---. Oxidative Stress From Diverse Developmental Neurotoxicants: Antioxidants Protect Against Lipid Peroxidation Without Preventing Cell Loss. 2010 Mar; 32, (2): 124-131.

Rec #: 44189

Notes: Chemical of Concern: CPY
Abstract: Abstract: Oxidative stress has been hypothesized to provide a mechanism by which apparently unrelated chemicals can nevertheless produce similar developmental neurotoxic outcomes. We used differentiating PC12 cells to compare the effects of agents from four different classes and then to evaluate antioxidant amelioration: fipronil, perfluorooctanesulfonamide (PFOSA), dieldrin and chlorpyrifos. The rank order for lipid peroxidation corresponded to the ability to evoke cell loss: fipronil>PFOSA>dieldrin>chlorpyrifos. The same sequence was found for an index of cell enlargement (protein/DNA ratio) but the effects on neurite outgrowth (membrane/total protein) diverged, with fipronil producing a decrease and PFOSA an increase. Cotreatment with antioxidants reduced (ascorbate) or eliminated (Vitamin E) lipid peroxidation caused by each of the agents but failed to protect against cell loss, with the sole exception of chlorpyrifos, for which we earlier showed partial protection by Vitamin E; addition of higher NGF concentrations protected neither against oxidative stress nor cell loss. Despite the failure to prevent cell loss, ascorbate protected the cells from the effects of PFOSA on neuritic outgrowth; NGF, and to a lesser extent, ascorbate, offset the effects of fipronil on both cell enlargement and neuritogenesis. At the same time, the ameliorant treatments also worsened some of the other toxicant effects. Our results point out the problems in concluding that, just because a neurotoxicant produces oxidative stress, antioxidant therapy will be effective in preventing damage. Instead, additional mechanisms for each agent may provide alternative routes to neurotoxicity, or may be additive or synergistic with oxidative stress.

Abstract: Abstract: Age-dependent chlorpyrifos (CPF) metabolism was quantified by in vitro product formation in human hepatic microsomes (ages 13 days to 75 years) and plasma (ages 3 days to 43 years) with gas chromatography-mass spectrometry. Hepatic CPF cytochrome P450 desulfuration [CPF to chlorpyrifos-oxon (CPF-oxon)] and dearylation (CPF to 3,5,6-trichloro-2-pyridinol) V(max) values were 0.35 +/- 0.21 and 0.73 +/- 0.38 nmol . min(-1) . mg microsomal protein (-1) (mean +/- S. D.), respectively. The mean (+/- S.D.) hepatic CPF-oxon hydrolysis (chlorpyrifos-oxonase [CPFOase]) V(max) was 78 +/- 44 nmol . min(-1) . mg microsomal protein (-1). None of these hepatic measures demonstrated age-dependent relationships on a per microsomal protein basis using linear regression models. Ratios of CPF bioactivation to detoxification (CPF desulfuration to dearylation) V(max) values were consistent across ages. CPFOase in plasma demonstrated age-dependent increases on a volume of plasma basis, as did total plasma protein levels. Mean (+/- S.D.) CPF-oxon hydrolysis V(max) values for children <6 months of age and adults (>= 16 years) were 1900 +/- 660 and 6800 +/- 1600 nmol . min(-1) . ml(-1), respectively, and at environmental exposure levels, this high-capacity enzyme is likely to be sufficient even in infants. Plasma samples were phenotyped for paraoxonase status, and frequencies were 0.5, 0.4, and 0.1 for QQ, QR, and RR phenotypes, respectively. These results will be integrated into a physiologically based pharmacokinetic and pharmacodynamic model for CPF and, once integrated, will be useful for assessing biological response to CPF exposures across life stages.

Rec #: 69519
Notes: Chemical of Concern: CPY
Abstract: Abstract: Background: Biomonitoring is used in exposure and risk assessments to reduce uncertainties along the source-to-outcome continuum. Specifically, biomarkers can help identify exposure sources, routes, and distributions, and reflect kinetic and dynamic processes following exposure events. A variety of computational models now utilize biomarkers to better understand exposures at the population, individual, and sub-individual (target) levels. However, guidance is needed to clarify biomonitoring use given available measurements and models. Objective: This article presents a biomonitoring research framework designed to improve biomarker use and interpretation in support of exposure and risk assessments. Discussion: The biomonitoring research framework is based on a modified source-to-outcome continuum. Five tiers of biomonitoring analyses are included in the framework, beginning with simple cross-sectional and longitudinal analyses, and ending with complex analyses using various empirical and mechanistic models. Measurements and model requirements of each tier are given, as well as considerations to enhance analyses. Simple theoretical examples are also given to demonstrate applications of the framework for observational exposure studies. Conclusion: This biomonitoring framework can be used as a guide for interpreting existing biomarker data, designing new studies to answer specific exposure- and risk-based questions, and integrating knowledge across scientific disciplines to better address human health risks.

Abstract: Abstract: Organophosphorus-induced delayed polyneuropathy (OPIDP) is a syndrome induced by certain organophosphorus compounds (OPs) through a mechanism based on the inhibition and further modification (aging) of neuropathy target esterase (NTE). OECD guidelines for testing the capability of OPs to trigger OPIDP include two in vivo tests with hens. Activities of acetylcholinesterase and NTE found in SH-SY5Y human neuroblastoma cells were inhibited by 10 different OPs with kinetics similar to those found with chicken brain enzymes (model system for in vivo and in vitro-ex vivo assays). NTE in SH-SY5Y cells inhibited by these OPs aged and reactivated similarly to that described for hen brain NTE ex vivo. In short, we have developed an alternative methodology for predicting the capability of OPs to induce OPIDP based on the inhibition kinetics of acetylcholinesterase and NTE and on the capability of OPs to age the inhibited NTE from SH-SY5Y cell line. The results obtained always agreed with the previously reported ex vivo results with hen brain. The developed methodology correctly predicted the neuropathic potential of the tested OPs in eight cases. The in vivo-in vitro discrepancies with two of the tested compounds can be explained on the basis of differences between in vivo and in vitro biotransformation. (C) 2010 Elsevier Ltd.

Abstract: Abstract: Serum albumin displays an esterase activity that is capable of hydrolysing the anti-cholinesterase compounds carbaryl, paraoxon, chlorpyrifos-oxon, diazoxon and O-hexyl, O-2,5-dichlorphenyl phosphoramidate. The detoxication of all these anti-cholinesterase compounds takes place at significant rates with substrate concentrations in the same order of magnitude as expected during in vivo exposures, even when these substrate concentrations are between 15 and 1300 times lower than the recorded K(m) constants. Our data suggest that the efficacy of this detoxication system is based on the high concentration of albumin in plasma (and in the rest of the body), and not on the catalytic efficacy itself, which is low for albumin. We conclude the need for a structure-activity relationship study into the albumin-associated esterase activities because this protein is universally present in vertebrates and could compensate for reduced levels of other esterases, i.e., lipoprotein paraoxonase, in some species. It is also remarkable that the biotransformation of xenobiotics can be reliably studied in vitro, although conditions as similar as possible to in vivo situations are necessary.

Abstract: Abstract: The suitability of competitive enzyme-linked immunosorbent assays (ELISAs) with chemiluminescent detection-based immobilized antigen (indirect assay) for rapid and accurate determination of chlorpyrifos in various food matrices was tested. The limit of detection (LOD) values were 1-1.75 ng mL-1, the standard curve midpoint (IC50) was 3.5 ng mL-1, and the assay duration was 1.5 h. Assay application to the analysis of honeybee extract resulted in chlorpyrifos recoveries varying between 62 and 83% in 5-15 ng mL-1 herbicide concentration range.

Abstract: Abstract: This paper reports the construction of the gold/mercaptobenzothiazole/polyaniline/acetylcholinesterase/polyvi nylacetat e (Au/ MBT/PANI/AChE/PVAc) thick-film biosensor for the determination of certain organophosphate pesticide solutions in selected aqueous organic solvent solutions. The Au/MBT/PANI/AChE/PVAc electrocatalytic biosensor device was constructed by encapsulating acetylcholinesterase (AChE) enzyme in the PANI polymer composite, followed by the coating of poly(vinyl acetate) (PVAc) on top to secure the biosensor film from disintegration in the organic solvents evaluated. The electroactive substrate called acetylthiocholine (ATCh) was employed to provide the movement of electrons in the amperometric biosensor. The voltammetric results have shown that the current shifts more anodically as the Au/MBT/PANI/AChE/PVAc biosensor responded to successive acetylthiocholine (ATCh) substrate addition under anaerobic conditions in 0.1 M phosphate buffer, KCl (pH 7.2) solution and aqueous organic solvent solutions. For the Au/MBT/PANI/AChE/PVAc biosensor, various performance and stability parameters were evaluated. These factors include the optimal enzyme loading, effect of pH, long-term stability of the biosensor, temperature stability of the biosensor, the effect of polar organic solvents, and the effect of non-polar organic solvents on the amperometric behavior of the biosensor. The biosensor was then applied to detect a series of 5 organophosphorous pesticides in aqueous organic solvents and the pesticides studied were parathion-methyl, malathion and chlorpyrifos. The results obtained have shown that the detection limit values for the individual pesticides were 1.332 nM (parathion-methyl), 0.189 nM (malathion), 0.018 nM (chlorpyrifos).

ABSTRACT: The oocyte of the domestic dog is unique from that of other mammalian species studied to date. Ovulation occurs either once or twice per year, with the oocyte released at the germinal vesicle stage, and then completing nuclear and cytoplasmic maturation within the oviduct under the influence of rising circulating progesterone. In vivo meiotic maturation of the bitch oocyte is completed within 48-72 h after ovulation, which is longer than 12-36 h required for oocytes from most other mammalian species. Due to these inherently novel traits, in vitro culture systems developed for maturing oocytes of other species have been found inadequate for maturation of dog oocytes. On average, only 15-20% of ovarian oocytes achieve the metaphase II stage after 48-72 h of in vitro culture. Thus far, no offspring have been produced in the dog (or other canids) by transferring embryos derived from in vitro matured oocytes. This review addresses current knowledge about dog reproductive physiology, specifically those factors influencing in vitro developmental competence of the oocyte. This summary lays a foundation for identifying the next steps to understanding the mechanisms regulating meiotic maturation and developmental competence of the dog oocyte.

Abstract: Abstract: This study presents the bioavailability of four spiked compounds to Lumbriculus variegatus, in sediment samples from three river basins in Europe: the Elbe, the Llobregat, and the Scheldt. Twenty sediment samples differing in physical and chemical properties were spiked with chlorpyrifos, pyrene, tetrachloribiphenyl, and tetrabromo diphenyl ether. The main focus of this study was to compare the suitability of two chemical approaches--the rapidly desorbing fraction method based on the Tenax® extraction and the freely dissolved chemical concentration method based on polyoxymethylene passive sampling--for predicting the bioavailability of sediment-associated hydrophobic compounds. It appears that accessible concentration estimated by Tenax extraction does not result in equal freely dissolved concentrations based on polyoxymethylene passive sampling results. The present data show that freely dissolved concentration in pore water mainly determines the uptake by organisms and, therefore, the polyoxymethylene passive sampling method was a successful approach to estimating the bioavailability of sediment-associated lipophilic contaminants (log octanol-water partitioning coefficient >6). The sediment characteristics or river basin differences had only a minor effect on the bioavailability estimates. Overall, passive samplers have not been tested to a sufficient extent in various chemicals or exposure matrixes. For this reason, bioassays are still needed in the risk assessment process in order to verify results based on passive sampling methods. [PUBLICATION ABSTRACT]

Abstract: Abstract: Introduction. Organophosphate poisoning by oral or inhalation routes is characterized by a typical time-course of clinical features. Case presentation. We report a case of subcutaneous chlorpyrifos self-injection leading to a delayed cholinergic phase, prolonged coma, and severe permanent neurologic injury with electrophysiological patterns suggestive of overlapping intermediate syndrome and distal peripheral neuropathy. Time-course and severity of clinical features were not altered by either atropine or pralidoxime administration. Due to prolonged and severe alteration in consciousness, we used brain multimodal nuclear magnetic imaging and auditory cognitive event-related potentials to assess the patient's potential for awakening. Electrophysiological testing used to monitor muscle weakness showed the coexistence of 20 Hz-decremental responses in proximal muscles and severe denervation in distal muscles. Red blood cell acetylcholinesterase activity progressively normalized on day 60, while plasma butyrylcholinesterase activity remained low until day 100. Chlorpyrifos was detectable in serum until day 30 and urine metabolites for up to three months, supporting the hypothesis of a continuous chlorpyrifos release despite repeated surgical debridement. We suggest that adipose and muscle tissues acted as a chlorpyrifos reservoir. At one-year follow-up, the patient exhibited significant neuromuscular sequelae. Conclusion. Subcutaneous chlorpyrifos self-injection may result in severe toxicity with prolonged neurologic injury, atypical overlapping electrophysiological patterns, and a poor final outcome.

Abstract: Abstract: A new analytical method for the determination of 14 pesticide residues in fresh peppermint was developed based on the QuEChERS sample preparation technique followed by gas chromatography coupled to electron capture and nitrogen phosphorus detectors (GC/ECD/NPD). The validation study clearly demonstrated suitability of the method for its intended application. The overall recoveries of the pesticides from peppermint, at the three spiking levels of 0.01, 0.1 and 1.0 mg kg super(-1), were 100 % plus or minus 10 % with relative standard deviations of 6 % plus or minus 5 % on average. The limit of quantification was 0.01 mg kg super(-1) for all the pesticides. The expanded uncertainties were in the range between 7 % and 30 % (14 % on average), which was distinctively less than a maximum default value of plus or minus 50 %. Compared with our previous method, that entailed dichloromethane/acetone extraction and florisil column cleanup with collection of four fractions, the new method was more straightforward, less time and labour intensive as well as more sensitive, selective and accurate, simultaneously.

Abstract: Abstract: The decline of pelagic organisms in the San Francisco Estuary (SFE) (California, USA) is attributed to several factors, including water diversions, invasive species, and exposure to environmental toxicants. The present study evaluated the effects of environmental contaminants on liver vitellogenin, metallothionein, 7-ethoxyresorufin-O-deethylase (EROD), and benzyloxyresorufin O-deethylase (BROD) activity in juvenile striped bass (Morone saxitilis) in the SFE.
