Biomedical Sciences Faculty Research and Publications
In the central nervous system, cystine import in exchange for glutamate through system xc- is critical for the production of the antioxidant glutathione by astrocytes, as well as the maintenance of extracellular glutamate. Therefore, regulation of system xc- activity affects multiple aspects of cellular physiology and may contribute to disease states. Pituitary adenylate cyclase-activating polypeptide (PACAP) is a neuronally derived peptide that has already been demonstrated to modulate multiple aspects of glutamate signaling suggesting PACAP may also target activity of cystine–glutamate exchange via system xc-. In this study, 24-h treatment of primary cortical …

College of Nursing Faculty Research and Publications
Objective: This study examined mobility, self-efficacy, outcome expectations, neighborhood (density, destinations, and design), and neighborhood walking in older men (n = 106, 60-99 years, M = 76.78, SD = 8.12) and women (n = 216, 60-99 years, M = 75.81, SD = 8.46).
Method/Results: In hierarchical regression, the variables explained 32% of the variance in neighborhood walking in men (p < .001) and 27% of the variance in women (p < .01). Self-efficacy (β = .49, p < .01), density (β= .22, p < .05), and design (β= .21, p = .05) were associated with walking in men. Significant design characteristics included sidewalks (β= .25, p < .05) and crime (β= .36, p < .01). In women, self-efficacy (β= .48, p < .001) and destinations (β= .15, p < .05) were associated with walking. Walking was associated with self-efficacy for walking despite individual barriers in women (β= .38, p < .001) and neighborhood barriers in men (β= .30, p < .05).
Conclusion: Walking interventions targeting older women should incorporate local destinations. In older …

Skeletal muscle fatigue is characterized by the buildup of H+ and inorganic phosphate (Pi), metabolites that are thought to cause fatigue by inhibiting muscle force, velocity, and power. While the individual effects of elevated H+ or Pi have been well characterized, the effects of simultaneously elevating the ions, as occurs during fatigue in vivo, are still poorly understood. To address this, we exposed slow and fast rat skinned muscle fibers to fatiguing levels of H+ (pH 6.2) and Pi (30 mM) and determined the effects on contractile properties. At 30°C, elevated Pi …

There is considerable variability among individuals in musculoskeletal response to long-duration spaceflight. The specific origin of the individual variability is unknown but is almost certainly influenced by the details of other mission conditions such as individual differences in exercise countermeasures, particularly intensity of exercise, dietary intake, medication use, stress, sleep, psychological profiles, and actual mission task demands. In addition to variations in mission conditions, genetic differences may account for some aspect of individual variability. Generally, this individual variability exceeds the variability between sexes that adds to the complexity of understanding sex differences alone. Research specifically related to sex differences of …

Stress-Induced Cocaine Seeking Requires A Beta-2 Adrenergic Receptor-Regulated Pathway From The Ventral Bed Nucleus Of The Stria Terminalis That Regulates Crf Actions In The Ventral Tegmental Area, Oliver Vranjkovic, Paul J. Gasser, Clayton H. Gerndt, David A. Baker, John R. Mantsch
Biomedical Sciences Faculty Research and Publications
The ventral bed nucleus of the stria terminalis (vBNST) has been implicated in stress-induced cocaine use. Here we demonstrate that, in the vBNST, corticotropin releasing factor (CRF) is expressed in neurons that innervate the ventral tegmental area (VTA), a site where the CRF receptor antagonist antalarmin prevents the reinstatement of cocaine seeking by a stressor, intermittent footshock, following intravenous self-administration in rats. The vBNST receives dense noradrenergic innervation and expresses β adrenergic receptors (ARs). Footshock-induced reinstatement was prevented by bilateral intra-vBNST injection of the β-2 AR antagonist, ICI-118,551, but not the β-1 AR antagonist, betaxolol. Moreover, bilateral intra-vBNST injection of …

Estrous cycle-related fluctuations in delta-9-tetrahydrocannabinol (THC)-induced antinociception have been observed in the rat. The aim of this study was to determine which major ovarian hormone modulates the antinociceptive effects of i.c.v. THC, and whether hormone modulation of THC's behavioral effects could be due to changes in brain cannabinoid receptors (CBr). Vehicle (oil) or hormones (estradiol or progesterone, or both) were administered to female rats on days 3 and 7 post-ovariectomy. On the morning or afternoon of day 8 or day 9, vehicle or THC (100 μg) was administered i.c.v. Paw pressure, tail withdrawal, locomotor activity and catalepsy tests were conducted …

Pharyngeal And Cervical Cancer Incidences Significantly Correlate With Personal Uv Doses Among Whites In The United States, Dianne E. Godar, Rong Tang, Stephen Merrill
Mathematics, Statistics and Computer Science Faculty Research and Publications
Because we found UV-exposed oral tissue cells have reduced DNA repair and apoptotic cell death compared with skin tissue cells, we asked if a correlation existed between personal UV dose and the incidences of oral and pharyngeal cancer in the United States. We analyzed the International Agency for Research on Cancer's incidence data for oral and pharyngeal cancers by race (white and black) and sex using each state's average annual personal UV dose. We refer to our data as ‘white’ rather than ‘Caucasian,’ which is a specific subgroup of whites, and ‘black’ rather than African-American because blacks from other countries …

Factors that result in augmented reinstatement, including increased withdrawal period duration and high levels of cocaine consumption, may provide insight into relapse vulnerability. The neural basis of augmented reinstatement may arise from more pronounced changes in plasticity required for reinstatement and/or the emergence of plasticity expressed only during a specific withdrawal period or under specific intake conditions. In this study, we examined the impact of withdrawal period duration and cocaine intake on the magnitude of cocaine-primed reinstatement and extracellular glutamate in the nucleus accumbens, which has been shown to be required for cocaine-primed reinstatement. Rats were assigned to self-administer under …

Central injections of pituitary adenylate cyclase-activating polypeptide (PACAP) into the ventromedial nuclei (VMN) of the hypothalamus produce hypophagia that is dependent upon the PAC1 receptor; however, the signaling downstream of this receptor in the VMN is unknown. Though PACAP signaling has many targets, this neuropeptide has been shown to influence glutamate signaling in several brain regions through mechanisms involving NMDA receptor potentiation via activation of the Src family of protein tyrosine kinases. With this in mind, we examined the Src-NMDA receptor signaling pathway as a target for PACAP signaling in the VMN that may mediate its effects on feeding behavior. …

The mechanisms which contribute to the time-dependent recovery of resting ventilation and the ventilatory CO2 chemoreflex after carotid body denervation (CBD) are poorly understood. Herein we tested the hypothesis that there are time-dependent changes in the expression of specific AMPA, NMDA, and/or neurokinin-1 (NK1R) receptors within respiratory-related brain stem nuclei acutely or chronically after CBD in adult goats. Brain stem tissues were collected acutely (5 days) or chronically (30 days) after sham or bilateral CBD, immunostained with antibodies targeting AMPA (GluA1 or GluA2), NMDA (GluN1), or NK-1 receptors, and optical density (OD) compared. Physiological measurement confirmed categorization of each …

Patient Perceptions Of Patient-Empowering Nurse Behaviours, Patient Activation And Functional Health Status In Postsurgical Patients With Life-Threatening Long-Term Illnesses, Teresa Jerofke-Owen, Marianne E. Weiss, Olga Yakusheva
College of Nursing Faculty Research and Publications
Aim
To explore the trajectory of associations between the nursing care process of patient empowerment during postsurgical hospitalization and postdischarge patient self-management outcomes, specifically patient activation and functional health status.
Background
Patient-centred care models advocate for patient empowerment in long-term illness care. Postsurgical patients with life-threatening long-term illnesses frequently feel powerless, have unmet needs, decreased functional health status and high readmission rates; however, previous studies of patient empowerment have conceptualized empowerment as an outcome primarily in outpatient settings, with little attention paid to provider processes used to empower patients during hospitalizations.
Design
A non-experimental, prospective, correlational study.
Methods
This sample …

Psychometric Properties Of The Index Of Relocation Adjustment, Abir K. Bekhet, Jaclene Zauszniewski
College of Nursing Faculty Research and Publications
More and more American older adults are relocating to retirement communities, and they experience challenges in adjusting to new surroundings that may increase their depression and mortality. An instrument not previously tested in the United States, the Index of Relocation Adjustment (IRA), may help in early identification of poor relocation adjustment. This study examined the psychometric properties of the IRA using secondary data from a convenience sample of 104 older adults who relocated to 6 retirement communities in Northeast Ohio. Cronbach’s alpha was .86. The IRA was correlated with measures of positive cognitions (r = .48, p < .01) and relocation controllability (r = …
