Abstract:

Background: Vascular remodeling is a pathological process central to many cardiovascular diseases (CVDs). Vascular injury promotes a complex interplay between distinct cell populations in the vessel wall that results in endothelial dysfunction and local inflammation, which in turn stimulate vascular smooth muscle cell (SMC) proliferation and extracellular matrix (ECM) deposition, leading to neointimal thickening and stenosis. Different signaling pathways, including the melanocortin system (MCS), modulate vascular inflammation and oxidative stress. The MCS refers to a set of hormonal and paracr

Abstract:

A case control study comparing fasting lipid and apolipoprotein concentrations in NIDDM patients and normal control subjects matched for age, sex and body mass, reveals abnormalities of high density lipoproteins and apolipoprotein B containing lipoproteins despite hypoglycaemic therapy. HDL cholesterol concentration is reduced in these NIDDM patients, whilst apolipoprotein concentrations are similar to the controls. Therefore HDL particles may be cholesterol poor, possibly reflecting reduced reverse cholesterol transport. LDL cholesterol concentration may also be reduced in these patients whil

Abstract:

Cardiovascular disease (CVD) is the leading cause of global mortality, with the incidence of cardiovascular related pathologies remaining a public health burden. CVD encompasses pathologies of the vascular tree and heart, including, for example, peripheral artery disease, coronary heart disease and ischaemic stroke. Atherosclerosis is the primary pathological process leading to CVD and is characterised by a multifactorial pathophysiology that first manifests in the vascular endothelium. Termed endothelial dysfunction, this early marker of atherosclerosis has become a focus of interest for iden

Abstract:

People with type 2 diabetes are at increased risk of age-related cognitive impairment. Previous literature has focused on case-control studies comparing rates of cognitive impairment in patients with and without diabetes. Investigations of potential risk factors for cognitive impairment (including those with increased prevalence in diabetes, such as macrovascular disease, and diabetes-specific factors such as hypoglycaemia) in study populations consisting exclusively of patients with type 2 diabetes have been largely neglected. Moreover, previous studies have failed to take advantage of the ex

Abstract:

Insulin-like growth factor and insulin are phylogenetically closely related polypeptides and have large structural and biological similarities. Low circulating insulin-like growth factor-I (IGF-I), diabetes as well as insulin resistance have been implicated in the pathogenesis of cardiovascular disease, but the mechanisms involved are still not clear. Furthermore, little is known about direct effects of insulin-like growth factor-I (IGF-I) and insulin on human micro- and macrovascular cells. In these studies we investigated the expression and function of insulin-like growth factor-I receptors

Factors which may account for the high frequency of macrovascular disease in diabetics are age, sex, cigarette smoking, hypertension, obesity, lack of exercise, diet, hyperglycaemia, hyperinsulinaeroia, hypercholesterolaemia, hypertriglyceridaemia, low HDL-cholesterol concentration, elevated free fatty acid concentration and enhanced platelet aggregation. Twenty seven (13 men and 14 women) non-insulin-dependent diabetics and thirty eight age, height and weight matched healthy subjects (10 men and 28 women) were studied.

Abstract:

This dissertation provides a detailed exploration and valuable insights of type 2 diabetes management in the real-world setting. Incretin-based therapies and thiazolidinedione were found to provide higher chances of sustainable glycaemic and cardiovascular risk factor control, compared to older anti-diabetic treatment options. The project highlights alarming rates of the existing cardio-metabolic burden at the population level. Proper control in terms of timely intensification with anti-hyperglycaemic, anti-hypertensive, and anti-dyslipidemic therapies when needed, remains a key aspect to impr

Abstract:

Numerous investigators have presented evidence of increased mortality in patients with diabetes mellitus due to cardiovascular disease. The reasons for a predisposition to vascular pathology that, in the advanced state, can lead to atherosclerosis are still unclear. Our hypotheses were: 1) the condition of diabetes mellitus in a streptozocin animal model may show vascular changes similar to early pathology in macrovessels, 2) since the model is normotensive, inducing hypertension will result in early atherogenic pathology, 3) the response to diabetic and/or hypertensive circumstances
