A profile of the elderly admitted to the emergency unit of Groote Schuur Hospital : with particular reference to their health care needs
… (i) there is an interrelationship between the ageing process and disease; (ii) a non-disease-specific approach which focusses on the functional status of elderly patients can be used as a predictor of health services consumption; and (iii) any study which promotes understanding of the dynamics …

Molecular interventions to overcome the ageing of CNS stem cells
… transduction down the axon. Increasingly, the process of adult myelination is understood as a key process in learning, memory formation, and promoting overall CNS health. With ageing, the capacity for OPCs to both self- renew and differentiate into myelinating oligodendrocytes is impaired. This …

On the epigenetic ageing clock in humans
… few years as the most accurate biomarkers of the ageing process. However, little is known about the molecular mechanisms that control the rate of such clocks. In this thesis I focus on the study of the epigenetic ageing clock in humans. First, I review and benchmark statistical and computational …

Studies of the surface and bulk reactivity of calcium hydroxide
… to be due to various degrees of atmospheric ageing. The main process involved in the ageing process was confirmed to be carbonatation (or carbonation). This ageing process was then followed by analysing a sample of calcium hydroxide over a long time period (350 days) and by looking at …

Student nurse knowledge and attitudes about ageing, older people and working with them: Does nursing education make a difference?
Aim: The ageing of the population requires student nurses to be adequately prepared to provide a range of care to older people across a variety of care settings. This study involved the development, implementation and evaluation of educational interventions that focus on student learning in …

Promoting multi-omic rejuvenation in human and mouse somatic cells by transient reprogramming
Ageing can be defined as the gradual decline in fitness that occurs in most organisms. The ageing process is characterised by a variety of hallmarks at the cellular and molecular levels including alterations in the epigenome. Notably in the case of the epigenome, these alterations can be measured …

XPS and Carbon-13 NMR spectroscopic analysis of composite rocket propellants
… temperatures was used to simulate the propellant ageing process. In the XPS analysis, changes in the sources for the N(1s) and Cl(2p) photopeaks were investigated. The propellant loses "organic" nitrogen as it ages. Changes in the amount of Cl⁻ present are in doubt due to instrumental …

Respiratory muscle work and inspiratory muscle training on cytokines, oxidative stress and diaphragm fatigue in younger and older populations
… inflammation contributes significantly to the ageing process and age related diseases. Enhanced oxidative stress, glycogen depletion and diaphragmatic fatigue are all potential stimuli for this production. Whole-body exercise training can attenuate systemic inflammation and oxidative stress in …

A systems approach to identify novel ageing regulators in Caenorhabditis elegans
The UK population is ageing, as is true across the industrialised world. To solve this grand challenge, science can provide strategies to potentially improve the way humans age. One of this century’s greatest discovery stipulates that ageing follows not a random decline, but rather a genetically …

Možnosti využití přírody v podpoře duševního zdraví
… the concept of mental health, describes the ageing process, and explores the importance of nature-based interventions, including animal-assisted therapy and horticultural therapy, within the context of social work. The practical part is based on qualitative research conducted through …

Constitutive modelling of the skin accounting for chronological ageing
… biological tissue, is subject to chronological ageing, whereby there is a general breakdown of tissue function and a decline in mechanical properties. In addition to this, skin undergoes extrinsic forms of ageing through exposure to external factors such as ultraviolet radiation, air pollution …

Age-associated changes to calcium handling proteins across the whole heart
… for the development of cardiac problems. The ageing process causes significant changes to cardiac structure and function. These are linked with the elderly heart’s diminished ability to respond to cardiac demand and associated with the increased frequency of myocardial dysfunction and …

An examination of the role of sustained attention and regulatory focus in stereotype threat and older adults and experiences of perceptions of ageing
The ageing process is largely thought of as a purely biological process but there are consequential psychological and social aspects of ageing. Perceptions of ageing are how individuals see older adults and the ageing process. These perceptions can have powerful direct and indirect effects on the …

The Effects of Age on Gait and Functional Movement Characteristics in an Older Adult Population
The maintenance of function in an ageing population is essential to ensure current and future health in older people. The ability to walk independently in a range of situations and environments is key to successful ageing. Age-related gait adaptations including spatial-temporal parameters, joint …

The Negotiation of Midlife: Exploring the Subjective Experience of Ageing
This thesis explores the subjective experience of ageing with a particular focus on midlife. I argue that midlife signifies an important phase of transition in the life course which is often characterised by essential changes in personal circumstances. Although many of these changes are anticipated …

SOLAR MIRRORS CHARACTERIZATION FOR CONCENTRATING SOLAR POWER TECHNOLOGY
… in order to assess: - the most durable to ageing and weathering effects; - the different reflectance behavior with the variation of the solar incident angle. .For these reasons the work here proposed was carried out with an experimental apparatus composed by: - An Agilent Cary 5000 …

The ecology of paper mill by-product and its evaluation as a casing medium in the culture of Agaricus bisporus (Lange) Pilat
… content, derived from chemicals used in pulping processes. After deposition the sludge undergoes an ageing process during which it dries out and its salt content is reduced. This ageing can be reproduced and accelerated by improved drainage under controlled conditions. The paper mill sludge was …

Electrophysiological and Behavioural Markers of Associative Source Memory Decline in Normal Ageing
… M. Johnson, Hashtroudi, & Lindsay, 1993). The ageing process shows a progressive decline in memory (Cabeza, Anderson, Locantore, & Mcintosh, 2002) which is thought to be related to atrophy in regions of the brain which are essential for memory (Pasquier, 1999). Source memory is particularly …

Modelling environmental effects on fracture damage of natural fibre-reinforced polymer composites
… polyester composite subjected to environmental ageing conditions has been studied with the aim of modelling its effect on the composite fracture damage for the purpose of long-term performance prediction. The composite was accelerated aged by hydrothermal ageing by immersing test specimens in …
