Effects Of Neonatal Clomipramine Treatment On Photic And Non-Photic Circadian Phase Shifting In Rats, Suzanne M. Dwyer
Effects Of Neonatal Clomipramine Treatment On Photic And Non-Photic Circadian Phase Shifting In Rats, Suzanne M. Dwyer
Electronic Theses and Dissertations
Neonatal exposure to monoaminergic antidepressant drugs produces a wide variety of effects on the behavior and physiology of adult rats which parallel those observed in human depression. Monoaminergic neurotransmitter systems are involved in the regulation of both affective and circadian behaviors, and alterations in circadian rhythmicity have been observed in depressed patients and in several other animal depression models. The purpose of the present study was to explore circadian phase shifting following neonatal antidepressant treatment. Neonatal rats were divided into three treatment groups; a clomipramine-treated group, a saline-treated group, and an unhandled group. Daily injections of clomipramine (25 mg/kg SC), …
The Cardiac Correlates Of Attention In The Denervated Heart: A Study Of Infant Heart Transplant Recipients, Stephanie Dianne Griffone
The Cardiac Correlates Of Attention In The Denervated Heart: A Study Of Infant Heart Transplant Recipients, Stephanie Dianne Griffone
Loma Linda University Electronic Theses, Dissertations & Projects
The cardiac correlate of attention is a deceleration in heart rate, controlled by the parasympathetic division of the autonomic nervous system. This has been extensively studied in infants; the findings indicate that this deceleration is affected by a number of factors, several mediated by the vagus nerve. However, the effects of denervation on this response are not known. Studies with adult heart transplant recipients have shown attenuated acceleration in response to stressful mental tasks. This study investigated the cardiac response to attention in infants who had received a heart transplant, using a habituation paradigm. The hypothesis that they would show …
Locus Of Control, Coping, And Anticipatory Nausea In Women With Breast Cancer, Melinda L. Nielsen
Locus Of Control, Coping, And Anticipatory Nausea In Women With Breast Cancer, Melinda L. Nielsen
Loma Linda University Electronic Theses, Dissertations & Projects
Many cancer patients experience adverse chemotherapy-related side effects. The present study examined whether the perception that one can control and effectively cope with her treatment for breast cancer mitigate against any nausea and vomiting that she may experience in anticipation of chemotherapy treatments. Seventy-five women with breast cancer completed the Multidimensional Health Locus of Control Scale - Form C, the Krantz Health Opinion Survey, the Ways of Coping Scale - Revised, and the Morrow Assessment of Nausea and Emesis. As hypothesized, internal health locus of control was significantly positively related to positive reappraisal coping strategies. This relationship was moderated by …

Role Of The Dopamine D₁-Like Receptor In Amphetamine-Induced Behavioral Sensitization: A Study Using Dopamine D₁A-Receptor Deficient Mice, Patrick Eugene Karper
Role Of The Dopamine D₁-Like Receptor In Amphetamine-Induced Behavioral Sensitization: A Study Using Dopamine D₁A-Receptor Deficient Mice, Patrick Eugene Karper
Theses Digitization Project
The ability of the indirect dopamine agonist, amphetamine, to produce behavioral sensitization was assessed in adult D₁A-deficient and wild-type mice. It was originally predicted that : 1) dopamine (DA) D₁-like receptors are necessary for the occurrence of short- and long-term amphetamine-induced behavioral sensitization, 2) DA D₁-like receptors are necessary for environmental conditioning factors associated with amphetamine-induced behavioral sensitiazation, and 3) DA D₅ receptors are required for amphetamine-induced behavioral sensitization. Locomotor activity and sterotyped sniffing were assessed in each of three experiments.
