Abstract:

Stress activates a number of endocrine pathways that alter an animal's physiology in a manner which can result in undesirable meat quality. Animals frequently exhibit meat quality defects, including ecchymosis, at slaughter due to the stress of slaughter. This thesis explores how stress related hormones interact with adrenergic receptors to alter muscle and vascular physiology. Fallow deer were exposed to either a transciptional regulator (hydrocortisone), a beta adrenergic recptor agonist (clenbuterol) or a beta adrenergic receptor antagonist (propranolol).

Abstract:

The myocardial depression found during septic shock has been a subject of intense study for many years. Many theories exist as to the precise cause of this condition but in this thesis the role of the β-adrenergic receptor is examined. Some investigators have found reduced response to β-adrenergic stimulation in models of septic shock in animals. This is of interest to the clinician since adrenergic stimulation is a key manipulation in the management of septic shock. An animal model of septic shock was established using a comparatively small dose of <i>Escherichia coli</i> endotoxin infused in

Abstract:

Although a long standing convention maintained that G Protein Coupled Receptors (GPCRs) exist in the plasma membrane solely as monomers, substantial work over the last two decades has demonstrated that these ubiquitous receptors can and in many cases, preferentially, exist as homodimers, heterodimers, or higher order oligomers. Often, two GPCRs of the same class heterodimerize; it is less common for two GPCRs of different signaling pathways to interact. The work presented here studied the physical and functional interaction of two GPCRs from discrete classes, the Beta 2 Adrenergic Receptor

Abstract:

Congenital myasthenic syndromes (CMS) are a rare group of heterogeneous disorders, characterised by compromised neuromuscular transmission and symptoms of fatiguable muscle weakness. CMS is caused by mutations in genes that affect the structure and function of the neuromuscular junction (NMJ). In about 20% of CMS cases, patients have mutations in the gene DOK7; the protein product, DOK7, is crucial for maintaining the dense aggregation of acetylcholine receptor (AChR) clusters at the NMJ. DOK7-CMS patients do not respond to treatment with acetylcholinesterase inhibitors which are the first lin

It is well established that the steady-state accommodative response is characterised by temporal changes in lens power having 2 dominant frequency components: a low frequency component (LFC: < 0.6Hz) and a high frequency component (HFC: 1.0-2.2Hz). This thesis investigates various aspects of these microfluctuations of accommodation. The HFC of accommodative fluctuations was shown to be present in central and peripheral lens zones, although the magnitude of the rms of accommodative microfluctuations was found to be reduced in the lens periphery. These findings concur with the proposal that the

Thesis (MScMedSc)--Stellenbosch University, 2015.<br>ENGLISH ABSTRACT: It is well-established that transient activation of the β-adrenergic signalling pathway with ligands such as isoproterenol, formoterol and dobutamine, elicits cardioprotection against subsequent long periods of ischaemia. Initially the focus was on the β1- and β2-adrenergic receptors (β1-AR, β2-AR), but recently the β3-AR also emerged as a potential target in the treatment of heart disease. In heart failure, β1- and β2-AR are typically known to be down-regulated while β3-ARs, on the other hand, are up-regulated (Moniotte et

Abstract:

A time-of-day variation in myocardial contraction and its response to sympathetic stimulation of β-adrenoceptors (b-ADR) exists, which is reflected by time-of-day variations in intracellular calcium [Ca2+]i regulation and electrical activity. There are three isoforms of β-ADR (β1/β2/β3) and the functional outcome of each receptor differs. β1/β2-ADRs result in positive inotropism, whereas β3-ADR induces a negative inotropic effect, associated with nitric oxide (NO) signalling. The aims of this thesis were to determine the role of the β3-ADR in the time-of-day variation in the response to sympat

Abstract:

Desensitisation is defined as a failure of a signaling pathway to respond to chronic or repeated stimulation. The β-adrenergic receptor signaling pathway of the healthy adult heart is known to desensitise, and then regain the sensitivity to stimulation if given enough time to rest between stimulations (resensitisation). The fetal heart does not desensitise, and in animal models of heart failure, a permanent desensitisation have been observed. No isolated element of the signaling pathway have yet been proven to be the sole modulator of the desensitisation behavior. Therefore a mathematical mode

Abstract:

The bovine polymorphonuclear leukocyte (neutrophil) is a central component of the acute inflammatory response, and is capable of reacting to a myriad of pro-inflammatory chemical signals that have been characterized in the context of bovine respiratory disease (BRD). Human neutrophils and bovine macrophages are known to react to pro-inflammatory signals as well; however, they are also capable of responding to anti-inflammatory signals from the autonomic nervous system. In particular, activation of the beta2-adrenergic receptor on these cells decreases several aspects of inflammatory activity

Abstract:

Hypertension, or chronic blood pressure elevation, affects approximately a third of American adults and is responsible for $70 billion dollars annually in medical costs. Recent studies have attempted to identify genetic variants that influence cardiopulmonary function, including blood pressure regulation. This study seeks to determine whether a polymorphism in position -182 of the gene encoding the phenylethanolamine N-methyltransferase (PNMT) enzyme, which converts norepinephrine to epinephrine, influences catecholamine levels and cardiovascular function. Secondly, this study seeks to exp

Abstract:

A síndrome isquêmica miocárdica instável (SIMI) leva a importantes alterações neurovasculares, tais como à hiperativação simpática e a diminuição do fluxo sanguíneo muscular (FSM) tanto em repouso como durante manobras fisiológicas como o exercício. A presença de alguns polimorfismos na genética humana, como o dos receptores \'beta\'2-adrenérgicos Gln27Glu, apresenta importante associação com a funcionalidade cardiovascular em indivíduos saudáveis. Contudo, não é conhecido se em pacientes com SIMI, a presença dos polimorfismos do receptor \'beta\'2-adrenérgico leva a respostas neurovasculares
