A polyclonal antiserum was generated against a unique peptide fragment in the rat D4 dopamine (DA) receptor. The titer was monitored using solid-phase ELISA and once it was established, specificity was assessed using Chinese Hamster Ovary (CHO) cells, stably transfected with the full-length cDNA for the rat D4 DA receptor. Immunofluorescent staining(More)
Polyclonal antisera have been generated against two unique polypeptide fragments in the rat D1B dopamine (DA) receptor, as deduced from the cDNA sequence. Antisera titers were monitored using solid-phase ELISA. Once the titers were established, antisera specificity was determined using Chinese Hamster ovary (CHO) cells, stably transfected with the(More)
Individuals who volunteer as control subjects for clinical studies are regularly screened for Axis I diagnoses, but seldom screened for Axis II disorders. This study examined the relative rates of Axis II diagnoses among 341 volunteers passing an initial telephone screen for entry into biological research studies. Axis I and II diagnoses by DSM-IV were(More)
Although initial reports of genetic contributions to personality dimensions were promising, continued empirical support remains controversial. The focus has largely revolved around polymorphisms of the serotonin transporter gene-linked polymorphic region and the D4 dopamine receptor subtype. Equivocal findings likely stem from numerous sources including(More)
The striatal cellular coexpression patterns for the D(1A) and D2 dopamine (DA) receptor subtypes and the ionotropic excitatory amino acid (EAA) subunits of the N-methyl-D-aspartate (NMDA-R1) and the alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) (GluR1 and GluR2/3) receptor subunits were examined morphologically. Their coincidence was(More)
Research on intermittent explosive disorder (IED) has been hindered by vague and restrictive DSM-IV diagnostic criteria. Integrated research criteria have been developed for IED (IED-IR) that address the DSM-IV criteria's shortcomings. The purpose of this study was to examine the convergent and discriminant validity of the IED-IR criteria set by comparing(More)
Intermittent explosive disorder (IED) is the sole psychiatric diagnostic category for which aggression is a cardinal symptom. IED focuses on physical aggression, but researchers have argued for the inclusion of verbal aggression (VA) (e.g., arguing, threatening) as a part of the IED criteria set. The utility of VA in identifying clinically relevant(More)
Dopamine (DA) is known to modulate the post-synaptic response of the excitatory amino acid (EAA) neurotransmitters in the striatum. Thus the intrinsic neurons in this nucleus are potential sites of cross-interaction between these two systems. The recent isolation of 5 different DA receptor subtypes and more than 20 EAA subunits argues for a complicated(More)
A self-report questionnaire was developed to assess attributional and emotional responses to aversive, but socially ambiguous, actions by one or more provocateurs. Multiple vignettes were developed and were followed by questions related to attribution of the provocateur's intent and the subject's emotional response to the provocateur's actions. The(More)
No randomized clinical trials have evaluated the efficacy of psychotherapy for intermittent explosive disorder (IED). In the present study, the authors tested the efficacy of 12-week group and individual cognitive-behavioral therapies (adapted from J. L. Deffenbacher & M. McKay, 2000) by comparing them with a wait-list control in a randomized clinical trial(More)
