Pathology of uremic vascular diseases: calciphylaxis and arteriovenous fistula
… in the world, and those diagnosed with cardiovascular disease (CVD) are at a higher risk of mortality. Accumulated uremic toxins increases the risks of CVD in CKD patients and symptoms of CVD include endothelial injury, inflammatory reaction, vessel calcification and occlusion, and blood clot. …

Integrating inflammatory stimuli with macromolecules for therapy and sensing of vascular diseases
… with macromolecules for therapy and sensing of vascular diseases. To do so, specific features of nanoparticles were studied in Chapter 2 to engineer solutions for the prevailing problems in ischemia and cancer. This thesis presents three approaches in investigating the combination of these …

Unsupervised Representation Learning from Intravascular Ultrasound Videos
Vascular diseases such as atherosclerosis are a leading cause of mortality and morbidity worldwide. Intravascular Ultrasound (IVUS) is an imaging technology that has the distinctive ability to offer real-time endovascular information of the coronary vasculature. However, its low signal-to-noise …

Vascular Disease Pathogenesis In Smooth Muscle Dysfunction Syndrome and Majewski Osteodysplastic Primordial Dwarfism Type Ii
<p>Vascular diseases are a leading cause of morbidity and mortality world-wide. Understanding their pathogenesis is crucial to better diagnosis and management of these life-threatening conditions. Through the study of rare mutations that lead to early onset and severe vascular diseases, we can …

Endothelial cell plasticity as a marker of vascular disease and predictor of adverse outcomes to stress
… environments, a process crucial for maintaining vascular homeostasis. Loss of this plasticity is implicated in vascular diseases, where endothelial dysfunction and maladaptive responses exacerbate disease progression and limit therapeutic efficacy. We investigated the role of endothelial cell …

Smooth Muscle Hyperplasia Due to Acta2/Myh11 Mutations: Identification of Novel Pathology and Pathways Leading to Aneurysms and Diverse Vascular Occlusive Diseases
… (â-myosin heavy chain) cause diffuse and diverse vascular diseases, including thoracic aortic aneurysms and dissections (TAAD) and early onset coronary artery disease and stroke. The mechanism by which these mutations lead to dilatation of some arteries but occlusion of others is unknown. We …

Clinical Aspects on Chimney Stent Graft Technique in Endovascular Repair of the Aorta.
… and in patients unfit for major surgery. Endovascular aortic repair is safe, durable and effective when there is adequate proximal and distal sealing zone for the aortic stent graft. Fenestrated and branched stent grafts have made the repair possible for complex but elective cases that do not …

Depressive Symptoms and Subclinical Vascular Disease: A Cross-Cultural Comparison
… & Kessler, 2005). Markers of subclinical cardiovascular disease have been associated with depression, and rates of most cardiovascular risk factors are higher in African Americans than Caucasians (Shaya, Gu, & Saunders, 2007). Whereas rates of atherosclerosis are similar across these groups …

Uso do ácido acetilsalicílico na prevenção de doenças cardiovasculares.
Cardiovascular disease (CVD) is the leading cause of death both in developed and developing countries. Many efforts have been made towards the prevention of these diseases and the use of acetylsalicylic acid (ASA) is one such measure. The present work aims to compile updated information on the …

Stimulation of angiogenesis through growth factor delivery from synthetic heparinised hydrogels
Objectives: Vascular diseases are one of the leading causes of death. Due to minimal regenerative capability of the heart, alternative therapies have been sought after with engineered biomaterials being extensively investigated in this area. In this study, enzymatically degradable heparinised …

Finite element and mechanobiological modelling of vascular devices
There are two main surgical treatments for vascular diseases, (i) percutaneous stent deployment and (ii) replacement of an atherosclerotic artery with a vascular graft or tissue engineered blood vessel. The aim of this thesis was to develop computational models that could assist in the design of …

Aktivität und Bedeutung der erythrozytären NOS bei kardiovaskulären Risikofaktoren
In cardiovascular diseases changes in the metabolism of L-arginine-NO cause endothelial dysfunction with reduced bioavailability of NO. Besides endothelial cells, RBC also obtain an active NOS in the vascular system. NO synthesis by RBC-NOS is regulated by similar mechanism and modulates RBC …

The Role of Lipoprotein(a)/Apolipoprotein(a) in Endothelial Dysfunction: Mechanistic Studies in Vascular Endothelium
… risk factor for the development of a number of vascular diseases including coronary heart disease and stroke. Lp(a) consists of a low-density lipoprotein (LDL)-like moiety and an unique glycoprotein, apolipoprotein(a) (apo(a)), that is covalently attached to the apolipoproteinB-100 (apoB-100) …
