Abstract:

Thesis (MPH.) --University of Limpopo, 2015<br>Background: Uncorrected refractive errors remain a public health problem among different population and age groups worldwide, including South Africa. Refractive error has serious visual and functional impacts on those affected. In children, refractive errors may negatively affect the academic pursuits and activities of daily living such as reading. Aims and Objectives: To determine and document the prevalence, types and magnitude together with age and gender differences of refractive errors among primary school children in Motherwell Township, Ea

Abstract:

This research investigated the visual demands in modern primary school classrooms and also the impact of common refractive anomalies on a child's ability to perform academic-related tasks. The results showed that relatively high levels of visual acuity, contrast demand and sustained accommodative-convergence are required to perform optimally in the modern classroom environment. It was also demonstrated that relatively low magnitudes of uncorrected refractive error may have a detrimental impact on children's ability to perform academic-related activities at school, with sustained near work furt

Abstract:

A Thesis submitted to The University of Arizona College of Medicine - Phoenix in partial fulfillment of the requirements for the Degree of Doctor of Medicine.<br>Background: Esotropic strabismus is a condition in which the eyes are not properly aligned with each other. In children, uncorrected esotropia may result in permanent loss of vision due to amblyopia, a condition where the nonpreferred, crossing eye is suppressed. Early identification and treatment of esotropia in children is critical, as doing so may prevent permanent loss of vision.

Abstract:

Peripheral retinal characteristics have been shown recently to have an influence upon refractive error development, specifically myopia. Studies of peripheral refraction have shown that emmetropic subjects typically display a myopic peripheral refraction, whereas myopic subjects have been found to have relative hyperopic refraction in the periphery. Myopic and hyperopic subjects were recruited for the experiments detailed in this thesis, from the student population at Glasgow Caledonian University. Previous studies on human subjects have generally made comparisons between myopic and emmetropic

This thesis makes a contribution to that part of the economics literature that explores how behavioural economics can inform environmental economics. Theoretically, the thesis develops the concept of environmental morale. Empirically, the study investigates the role of environmental morale on individuals’ behaviour within two different contexts: recycling participation and intertemporal choices over different goods (i.e., money, environment, and health) and outcomes (i.e., gains and losses). Major objectives of this analysis are: to shed light on how environmental morale interplays with indivi

Abstract:

Purpose: Myopia is a common eye disorder affecting up to 90% of children in South East Asia and 30% of the population worldwide. Myopia of high severity is a leading cause of blindness around the world (4th to 5th most common). Changes and remodelling of the sclera i.e. increase cellular proliferation & increase protein synthesis within scleral cells (↑ scleral DNA) and thinning and lose of extracellular matrix of sclera (↓ scleral GAG synthesis) have been linked to myopic eye growth in animal models. Signals acting on the sclera are thought to originate in the retina, and are modulated by the

An association between major surgery in the elderly and precipitation of Alzheimers disease (AD) has been reported. Hyperoxia (100%) oxygen is commonly administered after surgery to increase the oxygen content of blood. However, hyperoxia is a potent cerebral vasoconstrictor and generator of free radicals, as is [beta]amyloid (A[beta];). This study was aimed at examining behavioral, neuropathological, and neurochemical effects of hyperoxia treatments in APPsw transgenic mice (Tg+), which have elevated brain A[beta]; levels by 3-4 months of age but are not yet cognitively-impaired.

Objectifs : Comparer les effets de la plongée à l'air et en apnée sur la vasodilatation d'origine endothéliale et le stress oxydant. Ensuite, tenter de prévenir la dysfonction endothéliale post-plongée par une supplémentation en antioxydants. Méthodes : La fonction endothéliale des grosses artères est évaluée par la dilatation flux-dépendante (FMD) et celle des petites par pléthysmographie. Les concentrations plasmatiques de monoxyde d'azote (NO) furent évaluées en mesurant les nitrites/nitrates par colorimétrie. Les effets de 30g de chocolat noir furent testés en supplémentation 1h30 avant la

Abstract:

La dysoxie (hypoxie/hyperoxie) résulte de l’inadéquation entre la consommation en oxygène et ses apports, provoquant altérations du métabolisme cellulaire et impact physiopathologique majeur. L’hypoxie et l’inflammation font intervenir les facteurs HIF-1a et NF-kB qui activent le système adénosinergique. L’hypoxie augmente la concentration d’adénosine, entraîne une surexpression d’A2AR et induit une immunosuppression lymphocytaire T. Nous avons fait l‘hypothèse que l’inflammation via NF-kB influençait la suppression lymphocytaire adénosinergique; qu’une hyperhomocystéinémie favoriserait l’infl

Abstract:

This study determines effects of oxygen levels on morphology and VEGF expression of developing chicken lungs following incubation in normoxia (21% O2), hypoxia (15% O2) or hyperoxia (30% O2), until developmental days 16 or 18. Lung morphology was assessed using light microscopy, while VEGF expression was determined with ELISA. In hypoxia, the proportion of parabronchial tissue and parabronchi including lumina increased from day 16 to 18 (61 to 68% and 74.2 to 82.2%, respectively). Non-parabronchial tissue was higher in hypoxia than in hyperoxia on day 16 (26 to 20%). However, by day 18, there

Abstract:

The alveolar epithelium is a key functional component of the air-blood barrier in the lung. Comprised of two morphologically distinct cell types, alveolar epithelial type I (ATI) and type II (ATII) cells, effective repair of the alveolar epithelial barrier following injury appears to be an important determinant of clinical outcome. The prevailing view suggests this repair is achieved by the proliferation of ATII cells and the transdifferentiation of ATII cells into ATI cells. Supplemental oxygen and mechanical ventilation are key therapeutic interventions in the supportive treatment of respira
