BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) is a developmental disorder characterised by symptoms of inattention, impulsivity and hyperactivity. The spontaneously hypertensive rat (SHR) is a well-characterised model of this disorder and has been shown to exhibit dopamine dysregulation, one of the hypothesised causes of ADHD. Since stress experienced in the early stages of life can have long-lasting effects on behaviour, it was considered that early life stress may alter development of the dopaminergic system and thereby contribute to the behavioural characteristics of SHR. It was hypothesized that maternal separation would alter dopamine regulation by the transporter (DAT) in ways that distinguish SHR …

A Non-Invasive Assay For Monitoring Stress Responses: A Comparison Between Wild And Captive-Reared Rainbowfish (Melanoteania Duboulayi), Amina Zuberi, Sinan Ali, Culum Brown
Aquaculture Collection
The stress response of wild and captive reared rainbowfish (Melanoteania duboulayi) following chasing by a simulated predator was examined. Cortisol release rate was monitored using a flow through system by measuring water borne hormone levels. Tests using known cortisol concentrations revealed that the technique yielded 95% of the cortisol present in the water. Cortisol release rates increased several fold in both populations after being chased but peaked at different time periods. Wild fish showed a typical stress response with release rate rising to (2.29±0.22 ng g−1 h−1) 2 h after exposure followed by rapid recovery. The captive-reared …

Stress affects various forms of cognition. We found that moderate stress enhanced late reversal learning in a mouse touchscreen-based choice task. Ventromedial prefrontal cortex (vmPFC) lesions mimicked the effect of stress, whereas orbitofrontal and dorsolateral striatal lesions impaired reversal. Stress facilitation of reversal was prevented by BDNF infusion into the vmPFC. These findings suggest a mechanism by which stress-induced vmPFC dysfunction disinhibits learning by alternate (for example, striatal) systems.

Nurses who work with patients with Alzheimer's disease (AD) are especially vulnerable to the effects of stress and burnout. Many are poorly trained to cope with the emotional and behavioral problems of these residents and are repeatedly frustrated by their inability to manage these recurrent problems. Specialized care units (SCUs) reduced stress in the areas of staff knowledge, abilities, and resources. The SCU was designed specifically to provide the special environmental structures, support, and service systems required for the care of persons with AD that would enhance functioning and decrease associated behavioral problems. Support groups can assist nurses to recognize …

Children's distress during medical procedures can be decreased when professionals or parents provide distraction coaching, but the quality of distraction may contribute to the variation in the results. This article describes the development of the Distraction Coaching Index (DCI), a tool for measuring the quality and frequency of distraction coaching. Nominal group technique and consensus agreement were used for concept clarification and development of behavioral indicators and descriptors. Videotapes of untrained parents, trained parents, and expert professional coaches, who provided distraction to children (4-10 years old) undergoing peripheral intravenous catheter insertion, were used to assess interrater reliability and construct validity. …

Children's Responses To Sequential Versus Simultaneous Immunization Injections, M. Horn, Ann Mccarthy
Ann Marie McCarthy
INTRODUCTION: The purpose of this study was to compare distress behaviors and perceptions of distress in 4- to 6-year-old children who received two immunization injections simultaneously with those in children who received their immunizations sequentially. METHOD: This experimental study used a convenience sample of 46 children scheduled for pre-kindergarten examinations. The children were randomly assigned to either a sequential injection or a simultaneous injection group. Direct observation and videotapes were made of the children's behaviors before and after injection. Distress behaviors were analyzed with the Observation Scale of Behavioral Distress-Revised, and perceptions of distress were obtained from both children (with …

Strategies For Salivary Cortisol Collection And Analysis In Research With Children, Kirsten Hanrahan, Ann Mccarthy, Charmaine Kleiber, S. Lutgendorf, E. Tsalikian
Ann Marie McCarthy
Salivary cortisol has emerged in pediatric research as an easy-to-collect, relatively inexpensive, biologic marker of stress. Cortisol is highly variable and is responsive to a wide range of factors that should be considered when incorporating this measure into research with children. Strategies for sample collection include: (1) standardizing the time for sample collection, including baseline samples; (2) using consistent collection materials and methods; (3) controlling for certain drinks, foods, medications, and diagnoses; and (4) establishing procedures and protocols. Other strategies for laboratory analyses include: (1) selecting the appropriate assay and laboratory; (2) identifying units of measure and norms; and (3) …
Parent Behavior And Child Distress During Urethral Catheterization, Charmaine Kleiber, Ann Marie Mccarthy
Parent Behavior And Child Distress During Urethral Catheterization, Charmaine Kleiber, Ann Marie Mccarthy
Charmaine Kleiber
ISSUES AND PURPOSE: Researchers need a clear understanding of the natural behaviors parents use to help their children cope. This study describes the relationships between naturally occurring parent behaviors and child distress behaviors during urethral catheterization. DESIGN AND METHODS: In this descriptive study, researchers videotaped the behaviors of parent-child interactions during urethral catheterization. RESULTS: Parents used distraction to maintain calm behavior during the first part of the procedure and used more reassurance when the children started to become distressed. Seven of the nine children displayed calm behavior at least half the time following distraction. Parental reassurance did not decrease distress …
Narratives Of Family Caregiving: Four Story Types, Lioness Ayres
Narratives Of Family Caregiving: Four Story Types, Lioness Ayres
Lioness Ayres
RESULTS/CONCLUSIONS: This study used a combination of across-case, thematic analysis and within-case, narrative analysis to develop a typology of stories for family caregivers. Both researchers and clinicians can benefit from interpretive methods that offer access s into the processes and products of making meaning though stories. It is often easier to see the possibilities for reinterpretation from outside a story than from within it. It may be that nurses will also be uniquely able to help clients who are in the process of "getting the story straight" to find new, more sustaining meanings and even to live more happily ever …

Preferential Quadriceps Activation In Female Athletes With Incremental Increases In Landing Intensity, Kevin R. Ford, Gregory D. Myer, Laura C. Schmitt, Timothy L. Uhl, Timothy E. Hewett
Physical Therapy Faculty Publications
The purpose of this study was to identify alterations in preparatory muscle activation patterns across different drop heights in female athletes. Sixteen female high school volleyball players performed the drop vertical jump from three different drop heights. Surface electromyography of the quadriceps and hamstrings were collected during the movement trials. As the drop height increased, muscle activation of the quadriceps during preparatory phase also increased (p < .05). However, the hamstrings activation showed no similar increases relative to drop height. Female athletes appear to preferentially rely on increased quadriceps activation, without an increase in hamstrings activation, with increased plyometric intensity. The resultant decreased activation ratio of the hamstrings relative to quadriceps before landing may represent altered dynamic knee stability and may contribute to the increased risk of ACL injury in female athletes.

Adipose-derived stem cells (ASCs) possess significant therapeutic potential for tissue engineering and regeneration. This study investigates the endothelial differentiation and functional capacity of ASCs isolated from elderly patients. Isolation of ASCs from 53 patients (50-89 years) revealed that advanced age or comorbidity did not negatively impact stem cell harvest; rather, higher numbers were observed in older donors (>70 years) than in younger. ASCs cultured in endothelial growth medium-2 for up to 3 weeks formed cords upon Matrigel and demonstrated acetylated-low-density lipoprotein and lectin uptake. Further stimulation with vascular endothelial growth factor and shear stress upregulated endothelial cell-specific markers (CD31, …

The side effects of cancer therapy on normal tissues limit the success of therapy. Generation of reactive oxygen species (ROS) has been implicated for numerous chemotherapeutic agents including doxorubicin (DOX), a potent cancer chemotherapeutic drug. The production of ROS by DOX has been linked to DNA damage, nuclear translocation of p53, and mitochondrial injury; however, the causal relationship and molecular mechanisms underlying these events are unknown. The present study used wild-type (WT) and p53 homozygous knock-out (p53(-/-)) mice to investigate the role of p53 in the crosstalk between mitochondria and nucleus. Injecting mice with DOX (20 mg/kg) causes oxidative stress …

Mechanical Behavior Of Fully Expanded Commercially Available Endovascular Coronary Stents, Josip Tambaca, Suncica Canic, Mate Kosor, R David Fish, David Paniagua
The Texas Heart Institute Journal
The mechanical behavior of endovascular coronary stents influences their therapeutic efficacy. Through computational studies, researchers can analyze device performance and improve designs. We developed a 1-dimensional finite element method, net-based algorithm and used it to analyze the effects of radial loading and bending in commercially available stents. Our computational study included designs modeled on the Express, Cypher, Xience, and Palmaz stents.
We found that stents that did not fully expand were less rigid than the fully expanded stents and, therefore, exhibited larger displacement. Stents with an open-cell design, such as Express-like or Xience-like stents, had a higher bending flexibility. Stents …

Parental And Carer Responses To Angelman Syndrome And Prader-Willi Syndrome, Allyson K. Thomson
Theses: Doctorates and Masters
The research project undertaken as part of this thesis was designed to assess family stress levels and the use of coping strategies among the carers of people with an intellectual disability caused by Angelman syndrome (AS) or Prader-Willi syndrome (PWS). Both syndromes are genomic imprinting disorders that arise from disruptions in genes located within human chromosome 15q11-q13. Although the disease phenotypes are quite distinct, the genetic mechanisms involved are common to both syndromes but involve paternally-derived mutations in PWS as opposed to maternal mutations in AS. Previous investigations in Western Australia (WA) indicated that people with AS and PWS experience …
