Attention-deficit/hyperactivity disorder (ADHD) is a chronic neurobiological disorder exhibited by difficulty maintaining attention, as well as hyperactivity and impulsive behavior. Central nervous system (CNS) stimulants are the first line of treatment for ADHD. With the increase in number of adults on CNS stimulants, the question that arises is how well do we understand the long-term cardiova...

Amphetamine (Amp) increases exercise duration. It is thought to do so by masking fatigue, but there have been very few studies looking at the effect of amphetamine on VO2MAX and running economy. Furthermore, it is unknown if amphetamine's effect on exercise duration occurs in a warm environment. We conducted separate experiments in male Sprague-Dawley rats testing the effect of amphetamine on m...

Drugs and other forms of experience (e.g., complex housing) share the ability to alter the dendritic fields of cortical and subcortical neurons. Although such modifications are typically considered advantageous, recent research has demonstrated that psychomotor stimulants (cocaine and amphetamine) block subsequent experience-dependent structural plasticity in the nucleus accumbens (NAcc) and pa...

Attention-deficit/hyperactivity disorder (ADHD) is a behavioral disorder characterized by atypical levels of inattention, hyperactivity, and impulsivity that impair daily living activities. Although commonly associated with children and adolescents, current literature and practice now demonstrate the impairment the disorder may impose on adults as well. Central nervous system (CNS) stimulant me...

5,6,7,8-Tetrahydro-1,3-dioxolo[4,5-g]isoquinoline (TDIQ) is a conformationally restricted phenylalkylamine related in structure to amphetamine and N-methyl-1-(3,4-methylenedioxyphenyl)-2-aminopropane (MDMA) that does not act as a locomotor stimulant. To further evaluate this agent, a group of six rats was trained to discriminate 5.0 mg/kg of TDIQ from vehicle and tests of stimulus generalizatio...

Repeated intermittent amphetamine enhances efflux of dopamine through the dopamine transporter in rat basal ganglia and through the norepinephrine transporter in rat pheochromocytoma PC12 cells. Extracellular Ca2+ is required for the detection of this enhancement in the rat. In this study, we examined the role of Ca2+ and Ca2+ channels in the enhanced amphetamine-induced dopamine efflux that de...

attention-deficit/hyperactivity disorder (adhd) is a highly heritable neuropsychiatric disorder associated with significant impairments in occu pational, academic, neuropsychological, and social functioning. central nervous system (cns) stimulants are recommended as first-line medication therapy for children. cns stimulants include formulations of methylphenidate and amphetamine derivatives and...

Andersen - Tawil syndrome (ATS) is an autosomal - dominant or sporadic disorder characterized by ventricular arrhythmias, periodic paralysis, and distinctive facial and skeletal dysmorphism. Mutations in KCNJ2, which encodes the α-subunit of the potassium channel Kir2.1, were identified in patients with ATS. This genotype has been designated as type-1 ATS (ATS1). KCNJ2 mutations are detectable ...

INTRODUCTION Fatal poisonings among drug addicts in Denmark in 2012 were examined. Cause of death, abuse pattern and geographic differences are discussed and data are compared with previous studies. METHODS All fatal poisonings examined at the three institutes of forensic medicine in Denmark in 2012 were included in the study. RESULTS A total of 188 fatal intoxications were recorded. The me...
