Exposure to ethanol during development can lead to a constellation of congenital anomalies, resulting in prenatal and postnatal failure to thrive, central nervous system (CNS) deficits, and a number of patterning defects that lead to defects in the cardiovascular system, facial structures, and limbs. The cellular, biochemical, and molecular mechanisms by(More)
Methylmercury (MeHg) is a ubiquitous environmental pollutant and has been shown to affect learning in vertebrates following relatively low exposures. Zebrafish were used to model long-term learning deficits after developmental MeHg exposure. Selenomethionine (SeMet) co-exposure was used to evaluate its role in neuroprotection. Embryos were exposed from 2 to(More)
BACKGROUND Methylmercury (MeHg) is a known neurotoxic agent, but the mechanisms by which MeHg may act on reproductive pathways are relatively unknown. Several studies have indicated potential changes in hormone levels as well as declines in vertebrates with increasing dietary MeHg exposure. OBJECTIVES The purpose of this study was to identify alterations(More)
Lead (Pb) caused multiple effects on reproductive behavior and overall reproductive success. Adult fathead minnows (Pimephales promelas) were acclimated at a 16L:8D photoperiod to stimulate reproductive development. Reproductively mature adults were separated as male-female pairs and maintained for 4 weeks in either 0.0 or 0.5 ppm Pb. High lead(More)
There is a large body of evidence indicating important interactions between the adenosine and the opioid systems in regulating pain, opioid dependence and withdrawal. Mice lacking the proenkephalin gene and therefore lacking the endogenous enkephalin peptides have been successfully developed and exhibit decreased locomotor activity, are hyperalgesic and(More)
It is widely recognized that the nature and severity of responses to toxic exposure are age-dependent. Using active avoidance conditioning as the behavioral paradigm, the present study examined the effect of short-term methylmercury (MeHg) exposure on two adult age classes, 1- and 2-year-olds to coincide with zebrafish in relatively peak vs. declining(More)
Developmental bisphenol A (BPA) exposure has been implicated in adverse behavior and learning deficits. The mode of action underlying these effects is unclear. The objectives of this study were to identify whether low-dose, developmental BPA exposure affects larval zebrafish locomotor behavior and whether learning deficits occur in adults exposed during(More)
L-band (1-2 GHz) microwave radiometry is a remote sensing technique that can be used to monitor soil moisture, and is deployed in the Soil Moisture and Ocean Salinity (SMOS) Mission of the European Space Agency (ESA). Performing ground-based radiometer campaigns before launch, during the commissioning phase and during the operative SMOS mission is important(More)
OBJECTIVE To examine whether treatment of periodontal disease with scaling and root planing during pregnancy is associated with a reduction in the preterm birth rate. DESIGN Systematic review and meta-analysis of randomised controlled trials. DATA SOURCES Cochrane Central Trials Registry, ISI Web of Science, Medline, and reference lists of relevant(More)
The humanised anti-epidermal growth factor receptor (EGFR) monoclonal antibody matuzumab (formerly EMD 72000) is active against pancreatic cancer in preclinical studies. This phase I study assessed the safety and potential benefit of combined treatment with matuzumab and standard-dose gemcitabine. Three groups of chemotherapy-naive advanced pancreatic(More)
