Conditioned place preference (CPP), a commonly used model for studying the role of contextual cues in drug reward and drug seeking, was employed to explore possible behavioral interactions between (+/-)3,4-methylenedioxymethamphetamine (MDMA; "ecstasy") and cocaine. On each of four occasions, adult male rats received one of three doses of MDMA (0 mg/kg, 5(More)
RATIONALE Intravenous self-administration of cocaine at low doses is increased by chronic low-level exposure to lead during gestation and lactation (perinatal lead exposure). Insofar as drug potency is increased by early lead exposure, it must be considered that cocaine-seeking and relapse after periods of withdrawal similarly may be enhanced by perinatal(More)
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 males. Beginning on postnatal day (PND) 75, control (N=10) and lead-exposed (N=8) animals were trained to(More)
RATIONALE Developmental lead exposure has been found to produce differential patterns of drug self-administration in adult animals. OBJECTIVES The present study examined the effects of perinatal (gestation/lactation) lead exposure on adult patterns of heroin self-administration. METHODS Female rats were gavaged daily with 0 mg or 16 mg lead for 30 days(More)
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 on adult rates of acquisition of intravenous cocaine self-administration using an automated procedure that(More)
OBJECTIVE To evaluate the phenotypic spectrum associated with mutations in TBC1D24. METHODS We acquired new clinical, EEG, and neuroimaging data of 11 previously unreported and 37 published patients. TBC1D24 mutations, identified through various sequencing methods, can be found online (http://lovd.nl/TBC1D24). RESULTS Forty-eight patients were included(More)
Adenylosuccinate lyase (ADSL) deficiency is a rare autosomal recessive neurometabolic disorder that presents with a broad-spectrum of neurological and physiological symptoms. The ADSL gene produces an enzyme with binary molecular roles in de novo purine synthesis and purine nucleotide recycling. The biochemical phenotype of ADSL deficiency, accumulation of(More)
