Tissues of bowhead, beluga, and gray whales were analyzed for Ag, Cd, Cu, Se, Zn, THg and MeHg (belugas only). Delta15N and delta13C in muscle were used to estimate trophic position and feeding habitat, respectively. Trace element concentrations in t

Because prepubertal female rats maternally exposed to lead (Pb) exhibit suppressed serum levels of insulin-like growth factor-1 (IGF-1) and delayed puberty, we investigated the ability of centrally administered IGF-1 to stimulate luteinizing hormone

Concentrations of selected trace elements (Ag, Cu, Cd, Se, Zn, THg, and MeHg) were measured in tissues of subsistence-harvested ringed (Pusa hispida (Schreber, 1775)), bearded (Erignathus barbatus (Erxleben, 1777)), and spotted (Phoca largha Pallas,

The rate of acquisition of drug self-administration may serve as a predictor of later drug-taking behavior, possibly influencing the vulnerability to use drugs. The present study examined the effects of perinatal (gestation/lactation) lead exposure o

The present investigation examined the effects of perinatal lead exposure on cocaine self-administration following a GABAA antagonist pretreatment. Female rats were exposed to either 0 or 16 mg lead daily for 30 days prior to breeding with unexposed

This investigation examined the effects of perinatal cadmium exposure on subsequent self-administration of cocaine during the adult cycle. Female Sprague–Dawley rats were gavaged daily with 0.0 (14% sucrose solution, w/v) or 5.0 mg cadmium chloride
