The primary cause of cerebrovascular disease is atherosclerosis, to which many factors contribute. At first many saw atherosclerosis as a lipid-driven disease. Recently inflammation has appeared as a significant factor in the disease. Innate immune cells, for example monocytes and macrophages, are important in atherosclerosis. Toll-like receptors (TLRs) are the best-studied family of receptor in the immune system. Read More

Matrix metalloproteinases (MMP) comprise a family of at least 25 zinc-dependent endopeptidases that play a pivotal role in the physiopathology of the mammalian central nervous system. In the first phases after stroke, the dysregulation of MMPs has been described to increase acute neurovascular disruption and cerebral injury. In particular, MMP-mediated alterations lead to blood-brain barrier (BBB) leakage, cerebral Read More

During the last decades, the improvements in the assessment and management of cardiovascular risk have been successful in the reduction of acute cardiovascular outcomes. Among different prevention and therapeutic strategies, treatments targeting HDL increase have been indicated as promising interventions from both basic research and clinical studies. Although this therapeutic approach still requires confirmatory findi Read More

Stroke, a leading cause of death or disability worldwide, is frequently dependent on the rupture of carotid atherosclerotic plaques. It is therefore extremely important to study the mechanisms of formation, progression and eventually rupture of the plaques. Vulnerability of the plaque, the intrinsic tendency to lose its integrity and consequently to induce a dramatic atherothrombotic or embolic event, is still an elusive conce Read More

Plaque vulnerability due to inflammation has been shown to be a participating factor in the degenerative process in the arterial wall that contributes to stenosis and embolism. This is believed to have an important role to play also in the genesis of stroke or cerebrovascular diseases. In order to appropriately screen patients for treatment, there is an absolute need to directly or indirectly visualize both the normal carotid Read More

Inflammation, endothelial dysfunction, and platelet activation contribute to the prothrombotic pro-inflammatory state associated with AF. Inflammatory biomarkers, such as C-reactive protein and interleukin 6, promote the production of tissue factor (TF) and von Willebrand factor (vWF) and aggravate endothelial dysfunction leading to increased coagulation and depressed fibrinolytic activity. The interaction of vWF Read More

Dyslipidemia represents one of the major risk factors for atherosclerosis affecting the arteries of large and medium caliber and consequently causing ischemia in the brain, heart, or legs. Coronary artery disease and cerebral stroke represent the major causes of morbidity and mortality among the elderly and middle aged subjects. The change of lifestyle can reduce the risk of cardiovascular disease but available drug the Read More

Hypoxia, a condition of insufficient oxygen availability to support metabolism, occurs when the vascular supply is interrupted, as in stroke. The identification of the hypoxic and viable tissue in stroke as compared with irreversible lesions (necrosis) has relevant implications for the treatment of ischemic stroke. Traditionally, imaging by positron emission tomography (PET), using 15O-based radiotracers, allowed the measurem Read More

Neuroinflammation is a complex biological response to any injury occurring to the central nervous system. It is mainly characterized by the recruitment of immune system cells, namely the microglial cells, in the site of injury. Once activated, microglia expresses a cholesterol transporter protein (TSPO), previously also known as peripheral type benzodiazepine receptor. PK11195 is a ligand for TSPO and, labelled with a posi Read More

Prospective observational studies have shown that arterial stiffness is a strong and independent predictor of cardiovascular disease in hemodialysis patients. Recent evidence further supports that arterial hardening predicts cardiovascular and all-cause mortality in peritoneal dialysis patients, renal transplant recipients and patients with chronic kidney disease (CKD) not on dialysis. Of note, dissociation of arterial stiffness with bl Read More

Objective: To evaluate the impact of statins on carotid restenosis (CR) >50% and future cardiovascular events (CVE), in patients undergoing carotid endarterectomy (CEA). Methods: 570 consecutive patients (656 CEAs) operated between 1990 and 2009, were included in this retrospective study. The study cohort was followed for an average of 82 months (median 80, range 12- 180 months). Endpoints were the development of CR Read More

Warfarin inhibits vitamin-K dependent proteins involved in bone mineralization and the prevention of vascular calcification (bone Gla protein BGP, matrix Gla protein MGP). In this multicenter, cross-sectional study with 3-year follow-up, data from 387 patients on hemodialysis for ≥1 year at 18 dialysis units were analyzed. Patients on warfarin treatment for > 1 year (11.9% of the population) were compared with the remaining c Read More

Objective: Soluble receptor for advanced glycation end products (sRAGE) levels have been found to be decreased in chronic inflammatory diseases including atherosclerosis, hypertension and renal failure. This study evaluated the relationship between sRAGE concentrations and urinary albumin excretion in patients with essential hypertension. Methods: A total of 200 consecutive patients with essential hypertension were enrolled Read More

Background: Kallistatin (KS) is a serine proteinase. The result of KS on ‘Renal Ischemia- Reperfusion Injury’ (IRI) has not clearly been researched. In this study, investigative research has been conducted to draw results on the administration of human KS on kidney response conducted within a mouse model of IRI. Materials and Methods: BALB/c mice were used and given 30 min ischemia that was injected into the kidney which Read More
