Abstract:
SummaryTen patients for elective cholecystectomy were studied pre-, per- and postoperatively. All had neurolept anesthesia. Plasma concentrations of β-TG, TXB2 and 5-HT and intraplatelet 5-HT were measured. Aggregation to ADP was recorded.Serum cortisol concentration was used as index of the stress response, showing peroperative increase and postoperative decrease. Closely related to this we observed a significant increase in P-β-TG and P-TXB2 with postoperative normalization in 6 patients without complications. P-5-HT had a peak peropera-tively and remained elevated postoperatively. A negative correlation between P--5-HT and decreasing intraplatelet 5-HT postoperatively was observed.High postoperative levels of P--5-HT seem to be related to low arterial Po2 and pulmonary dysfunction. In 3 patients with complications a second increase in P-β-TG, P-TXB2 and partly in P--5-HT was found. Platelets were temporarily refractory to ADP immediately following surgery and showed increased aggregabil-ity postoperatively. We conclude that platelets are activated in surgical stress.

Abstract:
Little is known about neutrophil function, an important component of innate immunity, in relation to psychosocial factors. This thesis investigated the effect of acute and chronic psychological stressors on human neutrophil function among young and older adults. The first two studies examined the effects of an acute laboratory psychological stress task on neutrophil function in young and older adults, respectively. Blood samples to determine neutrophil function were taken at resting baseline, during acute stress and during recovery. In the first study (N=40), there was an acute increase in phagocytic ability and a reduction of superoxide production associated with the stress task relative to baseline. In study two (N =17), there was a significant reduction of neutrophil superoxide production associated with the stress task. Study three (N=48) examined the effect of chronic stress, a recent bereavement (<2 months), on neutrophil function in elders. Cortisol and dehydroepiandrosterone-sulphate (DHEAS) levels were determined in serum to assess potential mechanisms. Superoxide production was significantly reduced among the bereaved group when challenged with E. Coli; also, the bereaved had a significantly higher cortisol:DHEAS ratio compared to controls. Overall, this thesis shows that human neutrophil function is sensitive to both acute and chronic psychological stress exposures; however, more research is needed to determine the specific underlying mechanisms behind the observed alterations.

The primary aim of this dissertation was to evaluate the factors that contribute to the cardiorespiratory and vascular responses following exercise conditioning and microgravity deconditioning. The first study of this dissertation (Chapter 2) revealed that exercise training in the head down tilt posture, which places increases central blood volume compared to upright, results in cardiorespiratory adaptations in both upright and head down tilt postures which are not completely expressed with exercise training in the upright posture. These findings suggest that augmentation of the ventricular volume load during exercise training may result in adaptations that transfer across multiple body positions. In the second and third studies measurements of blood velocity and flow were performed via Doppler ultrasound. In Chapter 3 we observed that in the brachial and femoral arteries blood moves with a slightly blunted parabolic velocity profile that is very stable across a range of mean arterial pressures and downstream limb resistances. We concluded that these findings support the current calculations of shear rate based on the assumptions of laminar flow. With these assumptions confirmed, the investigation in Chapter 4 could be performed. We observed that acute exposure to a sustained antegrade shear rate, via unilateral forearm heating, increased measurements of flow-mediated dilation and the overall rate of adjustment for forearm blood flow and vascular conductance during dynamic handgrip exercise. These findings suggest that one potential stimulus for improvements in vascular function and health following exercise conditioning may be exposure to elevations in antegrade shear. Lastly in Chapter 5 we changed focus to the cardiorespiratory deconditioning following long-duration microgravity exposure. We retrospectively reviewed and analyzed previous investigations of microgravity deconditioning and demonstrated that the decrease in maximal O2 consumption ( O2max) occurs as a function of duration of exposure and that both convective and diffusive O2 transport pathways substantially contribute to this decline. In addition we reviewed the current literature and highlighted potential mechanisms, across several organ systems, which may contribute to this decline in O2max. Collectively, these studies revealed the breath of plasticity for cardiorespiratory adaptations to a variety of stressors.

Abstract:
Recently, adhesively bonded joints (ABJs) has found more rapidly increasing applications in aerospace and aeronautical structures, ground vehicles, and flexible electronics than mechanical fastening and welding technologies. However, outstanding issues still exist. This work was to develop a systematic semi-analytic method for accurate prediction of the interfacial shear and normal stresses of ABJs. Two unknown shear and peeling stress functions at each interface was first introduced in formulation, which satisfies all the traction boundary conditions. A set of governing ordinary differential equations (ODEs) was determined via triggering the theorem of minimum complimentary strain energy. Matlab? code was programmed to execute the proposed method. Furthermore, the present method was validated by finite element method and compared with those models in the literature. The present method is applicable for convenient scaling analysis and optimal design of ABJs and other types of ABJs such as adhesively bonded tubular and composite joints, etc.

Abstract:
Stress is one of the most critical influences on behavior, performance and disease. Recent findings from our laboratory have shown that stress represents a major modulator of motor function in the intact and damaged brain. The mechanisms by which stress and stress hormones affect motor system function, however, have not yet been determined. The objective of this thesis was to determine the route of action of stress and stress hormones on the motor system in a rat model. The first experiment investigates whether corticosterone is involved in mediating stress-induced motor impairments. The second experiment compares the role of glucocorticoid and mineralocorticoid receptors in regard to modulating the motor response to stress. The third experiment determines the differential effects of stress on motor function in males and females. The final experiment systematically describes changes in neuronal cell signaling that affect normal function of motor areas. The results indicate that disturbance of fine motor control by stress is not associated with stress hormone increases. Furthermore, it is modulated through the glucocorticoid and mineralocorticoid receptors. Stress differentially impairs motor function in males and females. These changes in motor behaviour could possibly be the result of changes in neuronal cell signaling within the motor system. This research provides new insights into physiological influences in motor system function and disorders of the motor system.

McCulloch, Andrew C. "The stress radionuclide assessment of diastolic function." Thesis, University of Glasgow, 2010. http://theses.gla.ac.uk/1878/.

Full text
Abstract:
Background Many patients are referred from primary care with suspected heart failure and are found to have preserved systolic function. These patients may be labelled as having normal ejection fraction or diastolic heart failure, the diagnosis of which is both controversial and difficult. Previous work has identified a large proportion of these patients to have an alternative, pre- existing diagnosis. This thesis prospectively assesses the prevalence of undiagnosed ischaemic heart disease and respiratory disease in this patient group and assess diastolic function using multiple methods. The central hypothesis being tested was that first third fractional filling, a radionuclide ventriculogram (RNVG) parameter previously used to assess diastolic function at rest, would identify diastolic dysfunction more accurately under stress conditions. Methods Patients were recruited from an open access echocardiography service. Echocardiography, including tissue Doppler assessment, was carried out independently by 2 experienced observers. Confounding diagnoses including coronary artery disease and respiratory disease were actively sought by myocardial perfusion imaging and spirometry. N-terminal proBNP was measured. List mode radionuclide ventriculography was performed at rest supine and during upright bicycle exercise with simultaneous measurement of VO2 max. Validation of the reliability and reproducibility of first third fractional filling, peak filling rate, time to peak filling and other radionuclide parameters of systolic and diastolic function was undertaken. This demonstrated that it was possible to measure both first third fractional filling and peak filling rate with the short acquisition times necessary for assessment during stress. Time to peak filling was poorly reproducible under these conditions. A normal range for first third fractional filling at rest and during exercise was established. Due to a strong inverse relationship between heart rate and first third fractional filling, a continuous reference range was constructed using an exponential model. This unique approach enables the calculation of the lower limit of normal at any heart rate. A more conventional mean ± 2 standard deviations was used for the other RNVG parameters. Results Eighty three patients were recruited and completed an extensive multi-modality assessment of systolic and diastolic function. As with previous work in this field, the patients were predominantly female (82%) and elderly (mean age 66.7). Mild left ventricular systolic dysfunction as determined by RNVG was missed by echocardiography in one third of patients. Systolic dysfunction more significant than this was not observed. N-terminal proBNP was elevated in 21 of 82 patients where it was available with no significant difference in left ventricular ejection fraction between those with normal and elevated levels. Myocardial perfusion scanning was normal in 46 of 83 patients and showed significant ischaemia in 20 of 83. Spirometry was normal in 58 of 82 patients, with mild airflow obstruction in 20 patients and moderate obstruction in 4. In only one patient were no alternative diagnoses present. There was poor correlation between indices of diastolic function at rest including first third fractional filling, echocardiographic parameters and NT-proBNP. The assessment of diastolic function using stress radionuclide ventriculography did not improve the correlation between measured indices. On stress, however, low first third fractional filling predicted exercise intolerance as an inability to reach anaerobic threshold. Conclusions Alternative diagnoses to diastolic dysfunction are present almost universally in patients with suspected normal ejection fraction heart failure. This is true even where these diagnoses are not previously established. This thesis underlines the need to fully assess this patient group to allow appropriate targeting of therapy. It is also clear that echocardiography alone is potentially misleading and it is suggested that it is better placed within a tiered assessment process. The assessment of diastolic function using stress radionuclide ventriculography, although an appealing concept, does not improve diagnostic accuracy within this patient group. The marked heterogeneity of this patient group is likely to have played a role in this and it may be of interest to reassess stress radionuclide ventriculography in a more acute heart failure population.

Full text
Abstract:
Complaints of poor memory by individuals with posttraumatic stress disorder (PTSD) have engendered research into attention and memory functioning in this disorder. Due to numerous methodological difficulties encountered in research with this group, results have been inconclusive. In Chapter 1 of this thesis the existing literature is reviewed to ascertain whether there is any evidence of a specific pattern of memory disorder associated with PTSD. Studies are reviewed for evidence of cognitive deficits relating to the structures of the limbic system. dysfunction in which has been implicated in PTSD. It is concluded that there is relatively good evidence of deficits related to probable frontal lobe functions. However, there is very little evidence of hippocampal related disorders and no studies have investigated memory functions relating to hypothesised roles of the amygdala in this group. In chapters 2 and 3 experiments are described that aim to investigate cognitive abilities related to amygdala functioning in PTSD. Chapter 2 investigates an hypothesised role of the amygdala in the consolidation of memory for emotional material. The results confirm the possibility of amygdala dysfunction in PTSD by showing that on a test of free recall participants with PTSD forgot emotional word stimuli at a faster rate than control participants, whereas non-emotional stimuli were forgotten at a more normal rate. Chapter 3 investigated a second hypothesised role for the amygdala in the recognition of facial expressions of fear and anger. Results showed that PTSD participants were somewhat impaired in their recognition of these expressions, which contrasted with an enhanced ability, associated with symptoms of hyperarousal, in identifying other negative facial expressions. In Chapter 4, the relevance of neuropsychological research to Clinical Psychology is discussed. It is argued that such research is vital if we are to fully understand the difficulties clients could face on a day-to-day basis.

Full text
Abstract:
The prefrontal cortex (PFC) is a brain region thought to mediate cognitive functions such as working memory. Chronic stress has been shown to reduce working memory. In this thesis study, the effect of chronic stress on PFC functions was assessed in adult rats.
First, contrary to previous evidences, chronic stress induces working memory performance alterations differentially in two populations of rats. One group displayed a decrease of performance only at 30 second delay, while the other had a decrease and increase at 0 and 30 seconds respectively.
Then, the effect of chronic stress on synaptic plasticity induction in the hippocampus-PFC network was investigated. High-frequency tetanic stimulation (HFS) of the dorsal hippocampus that induced long-term potentiation (LTP) in the prelimbic and infralimbic cortex in normal conditions was unable to induce LTP after chronic stress in the infralimbic cortex, whereas long-term depression (LTD) instead of LTP was induced in the prelimbic cortex.
Given that synaptic plasticity has been shown to depend on NMDA receptors in the PFC, NMDA subunit expressions before and after chronic stress was examined. There was a decrease of NR1 subunits expression in the prelimbic, but not infralimbic cortex. In contrast, the NR2A/NR2B ratio was increased in the infralimbic, but not prelimbic cortex. These results suggest that chronic stress disrupts PFC functions through dynamic modulation of distinct neural networks within the PFC.
Le cortex préfrontal (PFC) est une région du cerveau qui contrôle les fonctions cognitives comme la mémoire de travail. Dans cette thèse, l'effet du stress chronique sur des fonctions du PFC a été analysé chez des rats adultes.
Premièrement, les performances de la mémoire de travail ont été mesurées avant et après exposition au stress chronique. Nous avons constaté que le stress chronique induit des changements de performances de la mémoire de travail différemment selon deux populations de rats. Une des populations a démontré une diminution de performance seulement à 30 secondes de délai. Au contraire, l'autre a démontré une diminution de performance à 0 seconde et une amélioration de performance à 30 secondes.
En plus, nous avons évalué l'effet du stress chronique sur l'induction de la plasticité synaptique dans le réseau reliant l'hippocampe au PFC. Dans les conditions initiales, une stimulation tétanique à haute fréquence (HFS) dans l'hippocampe dorsal provoquait une potentialisation à long terme (LTP) dans le cortex prélimbique et infralimbique Or après exposition au stress chronique, une stimulation tétanique à haute fréquence n'a pas entraîné de potentialisation à long terme dans le cortex infralimbique. De plus, une exposition au stress chronique a provoqué l'apparition dans le cortex prélimbique d'une dépression à long terme (LTD) plutôt qu'une potentialisation à long terme.
Étant donné que la plasticité synaptique dépend des récepteurs de NMDA dans le PFC, nous avons examiné l'expression de sous-unité de NMDA avant et après exposition au stress chronique. En accord avec les changements synaptiques distincts de plasticité entre le cortex prélimbique et infralimbique après exposition au stress chronique, nous avons observé que l'expression de la sous-unité NR1 a diminué dans le prélimbique, mais non dans l'infralimbique. En revanche, le ratio de NR2A/NR2B a augmenté dans le cortex infralimbique, mais non dans le prélimbique. Ces résultats suggèrent que le stress chronique perturbe les fonctions du PFC par la modulation dynamique des réseaux distincts neurologiques dans le PFC.

Full text
Abstract:
Drives to develop more efficient pressure vessel and piping systems has led to complex geometry containing discontinuities such as holes, grooves, gaskets, crevices, notches etc. A multiaxial state of stress often develops in complex engineering components subject to creep conditions. Under multiaxial creep, the rupture life and creep ductility are not consistent with uniaxial creep experiments. A common practice to account for multiaxial creep is to introduce a scalar representative stress or strain that describes the multiaxial state within the materials enabling accurate predictions of rupture and creep ductility. Many functions have been proposed in literature and international pressure vessel and piping codes and standards. The ASME B&PV III, French RCC-MR, and British R5 recommends different phenomenological approaches to multiaxial creep. In this study, seven representative stress and eight representative strain functions are evaluated. The skeletal point approach to calibrating these functions is discussed. The incompressibility of the representative stress functions is analyzed. Rupture surfaces of the representative stress functions under biaxial stress conditions are generated to compare the advantages and limitations of the functions. Several functions are found to exhibit divide by zero errors and/or imaginary number errors leading to unstable and discontinuous rupture surfaces. It is observed that the selection of an appropriate representative function is dependent on loading condition, geometry, and material properties. The Hayhurst and Huddleston representative stress functions are found as the most suitable functions to predict multiaxial rupture for a general multiaxial stress states. Finally, a guideline to the selection of the appropriate representative stress function and the associated incompressibility condition is presented.

Abstract:
Temperature fluctuation from incomplete fluid mixing can induce fatigue cracks on structures of nuclear components, which should be prevented. For rational analysis of this phenomenon, the authors have developed a frequency transfer function that translates fluid temperature fluctuation to stress intensity factors. This function is formulated by a product of the effective heat transfer and the stress intensity factor functions, and enables us to quickly calculate stresses intensity factors induced by fluid temperature fluctuations. Furthermore, it can evaluate sensitivities of stress intensity factors to frequencies of temperature fluctuation, Biot number and constraint conditions of structures. Applicability of this function was verified through comparison with stress intensity factors calculated by the finite element method.

Abstract:
Propagation of a critical unstable crack under the action of static or varying stresses is determined by the intensity of strain field at tips of the crack. Stress intensity factor (SIF) is an important parameter in fracture mechanics, which is used as a criterion to judge the unstable propagation of a crack and plays an important role in calculating crack propagation life. SIF is related to both geometrical form and loading condition of a structure. In the paper, a weight function method is introduced to study crack propagation of center through cracks and edge cracks in a finite-size plate. In addition, finite element method, linear regression, and polynomial interpolating technique are used to simulate and verify the proposed method. Comparison studies among the proposed and current methods are performed as well. The results show that the weight function method can be used to calculate SIF easily.

Abstract:
The BARD program includes two main parts. In the first, experiments were conducted to complete our understanding of the mechanisms responsible for the impairment of reproductive functions under heat stress. Experiments focused on follicular development and function, since results obtained in our previous BARD project indicate that the preovulatory follicle is susceptible to heat stress. The theca cells, sensitive to thermal stress, produced less androgen during the summer, as well as during the autumn. Similarly, luteinized theca cells obtained from cows in summer produced much less progesterone than in winter. Granulosa cells and luteinized granulosa cells were less susceptible to heat stress. A delayed effect of heat stress on follicular development, on suppression of dominance and on steroid production by theca and granulosa cells was noted. This may be related to the low fertility of cows during the cool months of autumn. In the second part, experiments were conducted aiming to improve fertility in summer. The timed AI program was developed using two injections of GnRH coupled with PGF2a. It was found effective in improving reproductive performance in lactating cows. Limitations induced by heat stress on estrus detection were eliminated with the timed AI management program. Replacing the second injection of GnRH with hCG instead of GnRH agonist increased plasma progesterone levels post ovulation but did not improve fertility. Use of the timed AI program in summer, shortened days open and increased the net revenue per cow, however, it did not protect the embryo fiom temperature-induced embryonic mortality. Incorporation of a GnRH-agonist implant into the timed AJ program was examined. The implant increased plasma progesterone and LH concentrations and altered follicular dynamics. The use of a GnRH-implant enhanced pregnancy rate in cows with low body conditions. In a timed embryo transfer experiment, the use of fresh or frozen in vitro produced embryos was compared in the summer to improve fertility. The use of flesh embryos (but not frozen ones) improved pregnancy rate, however, substantial embryonic death occurred between 21 and 45 days. The timed AI program, which is now being used commercially, shortened days open, and increased pregnancy rate during summer. Other approaches which were found to improve fertility in small-scale studies, need to be tested again in large-scale field trials.
