The Impact Of The Chip Program On Depression And Well-Being: A Pilot Study, Carmen Diehl Thieszen
The Impact Of The Chip Program On Depression And Well-Being: A Pilot Study, Carmen Diehl Thieszen
Loma Linda University Electronic Theses, Dissertations & Projects
Reliable studies have demonstrated that intensive and comprehensive lifestyle changes can reduce coronary risk, which, in turn, can prevent, postpone, and reverse coronary heart disease (CHD) and affect its underlying atherosclerotic lesions. These well-established studies have focused their interventions on moderating biophysical risk factors. In the past 10 years, however, burgeoning research is supporting the idea that psychological factors, such as depression and well-being, are also important CHD risk factors. Little research has addressed, in a non-subjective way, how an intervention program focused on modifying biophysical risk factors may influence psychological factors. Using the Beck Depression Inventory-Short Form, the Dartmouth …
The Relationship Between Psychopathology In Caregivers And Their Children With Asthma, Jaime L. Benson
The Relationship Between Psychopathology In Caregivers And Their Children With Asthma, Jaime L. Benson
Honors Capstone Projects - All
Asthma is the leading chronic illness among children, and children with asthma have an increased risk not only for physical problems, but also for social and emotional difficulties related to their asthma. These risks are compounded when children have a caregiver who is depressed. The effects of maternal depression for children are complex and have been shown to persist into adolescence and adulthood. This is especially important because children with asthma, who are already at risk for psychopathology, may have increased internalizing and externalizing problems when their primary caregivers have depression or display depressive symptoms. Because depression affects cognitive functioning …
Intimacy, Orgasm Likelihood Of Both Partners, Conflict, And Partner Response Predict Sexual Satisfaction In Heterosexual Male And Female Respondents, R. Vernon Haning
Intimacy, Orgasm Likelihood Of Both Partners, Conflict, And Partner Response Predict Sexual Satisfaction In Heterosexual Male And Female Respondents, R. Vernon Haning
Theses, Dissertations and Capstones
Anonymous data provided by 417 female and 179 male sexually active heterosexual respondents showed that in long term sexual relationships sexual satisfaction was positively correlated with two different intimacy variables, the respondent’s orgasm likelihood, and the partner’s orgasm likelihood and negatively correlated with conflict in the relationship. All were significant predictors together in a multiple linear regression model. Empathic sexuality was defined as sexual response modulated by the sexual arousal or lack of arousal of the partner. Of 696 respondents, 90.3% reported empathic turn-on, 68% reported empathic turn-off, and 63.4% reported both empathic turn-on and turn-off, findings significantly different from …
Actions Of A Partial D2-Like Agonist During Low Or High Dopaminergic Tone: A Neurochemical Study Using Preweanling Rats, Shelly Taeko Yoshida
Actions Of A Partial D2-Like Agonist During Low Or High Dopaminergic Tone: A Neurochemical Study Using Preweanling Rats, Shelly Taeko Yoshida
Theses Digitization Project
The neurochemical effects of partial D2-like agonists (i.e., terguride) to alter striatal DOPA accumulation under high and low dopaminergic tone was examined in preweanling rats. The results indicate that terguride has agonist-like (quinpirole-like) effects under a low dopaminergic tone and antagonist-like (haloperidol-like) effects under a high dopaminergic tone during the preweanling period.
Effect Of Preweanling Methylphenidate Exposure On The Induction, Extinction And Reinstatement Of Morphine-Induced Conditioned Place Preference In Rats, Kellie Lynn Kucher
Effect Of Preweanling Methylphenidate Exposure On The Induction, Extinction And Reinstatement Of Morphine-Induced Conditioned Place Preference In Rats, Kellie Lynn Kucher
Theses Digitization Project
This study examined the effect of preweanling methyphenidate exposure on later drug reward. We examined the induction, extinction, and reinstatement of morphine induced conditioned place preference (CPP) in rats that received methylphenidate pretreatment during the preweanling period.
The Effect Of Early Psychostimulant Treatment On Abuse Liability And Dopamine Receptors, Steven Wayne Villafranca
The Effect Of Early Psychostimulant Treatment On Abuse Liability And Dopamine Receptors, Steven Wayne Villafranca
Theses Digitization Project
Examines whether the reinforcing properties of drugs of abuse were altered in adulthood by methylphenidate, more commonly known as Ritalin. Subjects were 108 rats of Sprague-Dawley descent (Harlan). Methylphenidate, or saline was administered daily to the subjects from the postnatal period (11-20 days old). The rats preference for morphine during early adulthood was measured using conditioned place preference. The number of dopamine D₂ receptors was measured in each rat and the correlation between receptor number and morphine preference was determined. Results indicate that rats pretreated with methylphenidate showed greater preference for morphine than saline pretreated rats and suggests that exposure …
192 Igg-Saporin Lesions Of The Nucleus Basalis Magnocellularis Impair Serial Reversal Learning In Rats, Sara Michelle Cabrera
192 Igg-Saporin Lesions Of The Nucleus Basalis Magnocellularis Impair Serial Reversal Learning In Rats, Sara Michelle Cabrera
Theses Digitization Project
In order to assess flexibility in acquiring and using conflicting response rules, rats with selective lesions of the NBM or sham-lesion controls were subjected to serial reversal training in a simple operant discrimination paradigm. The NBM lesion group did not differ from the control group in acquisition of the original rules; the NBM lesion group required more time to master the changes in rules in the first reversal, but not in subsequent reversals.
Cholinergic Basal Forebrain Involvement In The Acquisition Of Differential Reinforcement Of Low Rate Responding Tasks In Rats, Sean Ryan Corley
Cholinergic Basal Forebrain Involvement In The Acquisition Of Differential Reinforcement Of Low Rate Responding Tasks In Rats, Sean Ryan Corley
Theses Digitization Project
It was hypothesized that 192 IgG-saporin lesions of the basal forebrain cholinergic system (BFCS) would disrupt differential reinforcement of low rate (DRL) learning in an uncued DRL task, but would not impair acquisition and performance in the cued version of the task. Results suggest that BFCS lesions impair vigilance to the external cues despite continued practice in the cued DRL, whereas continuous attention to internally produced cues recovers with extended practice in the uncued DRL.
The Effects Of Neonatal Manganese Exposure On Impulsivity, Unlearned Motoric Function, And Reward, Carmela Marie Reichel
The Effects Of Neonatal Manganese Exposure On Impulsivity, Unlearned Motoric Function, And Reward, Carmela Marie Reichel
Theses Digitization Project
This study examined the effects of low to moderate doses of manganese (0, 250, or 750 _g per day from PD 1-21) on a comprehensive battery of behaviors in rats during the neonatal period, preweanling period, and in adulthood.
The Effect Of Delta9-Tetrahydrocannabinol (Thc) And Cb1 Antagonists On Sucrose And Quinine Palatability: Direct Measurement With The Taste Reactivity Test, Maegan Jarrett
Theses and Dissertations (Comprehensive)
Anecdotal reports suggest that cannabinoid agonists enhance palatability and that antagonists reduce palatability; however there has been little direct experimental evidence for these claims. The taste reactivity (TR) test is a direct measure of palatability in rats (Grill & Norgren, 1978). In Experiments 1 and 4, the taste reactivity (TR) test was used to evaluate the potential of delta-9-tetrahydrocannabinol (THC) to modify both sucrose and quinine palatability. The TR test revealed that THC (0.5 mg/kg) increases the palatability of sucrose solutions at 120 min post-injection, regardless of the sucrose concentration. THC (0.5 mg/kg) also decreased the aversiveness of the quinine …
