Artherosclerosis

Coronary artery disease (CAD) is a severe comorbidity in chronic kidney disease (CKD) due to heavy calcification in the medial layer and inflamed plaques. Chronic inflammation, endothelial dysfunction and vascular calcification are major contributors that lead to artherosclerosis in CKD. The lack of specific symptoms and signs of CAD and decreased accuracy of noninvasive diagnostic tools result in delayed diagnosis leading to increased mortality. MicroRNAs (miRNAs) are post-transcriptional regulators present in various biofluids throughout the body...

BACKGROUND: Patients with gout carry an excess risk for cardiovascular disease (CVD), but the contribution of subclinical atherosclerosis to the CVD risk has never been reported. In this study, we aimed to explore the predictive factors for incident major adverse cardiovascular events (MACE) in gout patients without a previous history of CVD or cerebral vascular disease. METHODS: A single-center, long-term follow-up cohort analysis was performed to assess subclinical atherosclerosis at baseline since 2008...

We describe a rare case of coronary artery aneurysm (CAA) with recurrent ST-elevation myocardial infarction (STEMI) despite being on standard dual antiplatelet therapy (DAPT). A 47-year-old male presented with chest pain and was found to have inferior wall STEMI along with diffuse right coronary artery (RCA) ectasia and proximal RCA aneurysm, thrombotic occlusion, and dissection. He was managed with extensive thrombectomy, angioplasty, prolonged Heparinization, and DAPT. The patient went on to have a similar presentation nine months later with a recurrent inferior wall STEMI with proximal RCA aneurysm and thrombotic occlusion managed with thrombectomy and bare metal stent placement...

The aim of the present European Stroke Organisation guideline is to provide clinically useful evidence-based recommendations on the management of patients with intracranial atherosclerotic disease (ICAD). The guidelines were prepared following the Standard Operational Procedure of the European Stroke Organisation guidelines and according to GRADE methodology. ICAD represents a major cause of ischemic stroke worldwide, and patients affected by this condition are exposed to a high risk for future strokes and other major cardiovascular events, despite best medical therapy available...

Advances in magnetic materials have enabled the development of new therapeutic agents which can be localised by external magnetic fields. These agents offer a potential means of improving treatment targeting and reducing the toxicity-related side effects associated with systemic delivery. Achieving sufficiently high magnetic fields at clinically-relevant depths in vivo, however, remains a challenge. Similarly, there is a need for techniques for real-time monitoring that do not rely on magnetic resonance imaging (MRI)...

BACKGROUND: Some researchers have suggested that parents' exposure to poor socioeconomic conditions during childhood can increase their offspring's risk of cardiovascular disease, primarily through poor maternal nutrition and growth. However, epidemiological data on this association are limited. In an intergenerational cohort from rural India, we examined the association of parental childhood socioeconomic conditions and stature with offspring's cardiovascular risk, hypothesising an inverse association between the two...

Osteoarthritis (OA) is one of the most common degenerative joint diseases worldwide. Chondrocytes are activated in OA patients, accompanied by excessive chondrogenic proliferation and production of inflammatory cytokines. MiR-467b is implicated in the regulation of artherosclerosis and pro-inflammatory cytokine secretion. However, the precise role of miR-467b in OA remains unclear. In the present study, we induced inflammation in chondrogenic ATDC5 cells using lipopolysaccharide (LPS). LPS treatment significantly elevated the production of interleukin-6 (IL-6), IL-1β and tumour necrosis factor-α (TNF-α) in ATDC5 cells, accompanied by decreased miR-467 level...

Detecting myeloperoxidase (MPO) activity in living organisms is important because MPO contributes to the pathogenesis of many diseases such as rheumatoid arthritis and other inflammatory diseases, artherosclerosis, neurodegenerative disease, and some cancers. However, rapid and effective methods for the detection of basal MPO activity in living systems have not yet been reported. Herein, we report a near-infrared (NIR) emissive "turn-on" probe FD-301 that can specifically bind to MPO and accurately measure MPO activity in living cells and in vivo via a rapid response to initial hypochlorous acid (HOCl), produced by MPO...

Introduction: Diabetes mellitus (DM) and its related sensory peripheral neuropathy (SPN) are the biggest risk factors for foot ulcer formation and lower limb amputation. Reduced vibration perception results in less sensitivity to pressure and is a known risk factor for diabetic foot ulcers. Improving vibration perception in the feet of people with SPN could be protective against foot ulcers. The aim of this study was to determine if a therapeutic vibrating insole, used for 35 consecutive days, could improve vibration perception in a patient with type 2 DM...

Inflammation, which plays a critical role in atherosclerosis and the occurrence of acute cardiovascular events, may be a new target for treatment of coronary artery disease (CAD) to reduce residual cardiovascular risk. Recently, Antiinflammatory Therapy with Canakinumab for Atherosclerotic Disease (CANTOS), the largest scale clinical trial that targeted inflammation but not lipids, has affirmed for the first time the inflammatory hypothesis of artherosclerosis and marked the advent of an exciting era of targeting inflammation for the prevention and treatment of cardiovascular diseases...

Migration inhibitory factor (MIF) has been shown to be critical in the pathology of early artherosclerosis; this article aim to investigate the plasma levels of MIF in hypertension plus hyperlipidemia patients.A total of 39 hypertension plus hyperlipidemia patients without any previous treatment were enrolled (HTN-HLP). Twenty-five healthy subjects were enrolled as the healthy control group (HEALTHY). Plasma MIF was measured by ELISA; laboratory and clinical characteristics were analyzed. HUVECs were treated with pooled plasma from HTN-HLP and HEALTHY groups, and the protein levels of adhesion molecules VCAM-1 and ICAM-1 were determined by ELISA...

BACKGROUND: Nitric oxide (NO) is the most powerful vasodilator that inhibits leukocyte adhesion, platelet aggregation, and vascular smooth muscle cell proliferation. However, excessive NO can cause lipid peroxidation and direct endothelial cell damage. Therefore, investigation of the role of NO in artherosclerosis development is important. Wen-Xin Decoction (WXD) has been shown to relieve myocardial ischemia reperfusion injury and prevent leukocyte adhesion and invasion; in addition, it can accelerate angiogenesis and prevent platelet activation and aggregation...

Vascular cell adhesion molecule 1 (VCAM1) is a member of the Immunoglobulin superfamily and encodes a cell surface sialoglycoprotein expressed in cytokine-activated endothelium. This type I membrane protein mediates leukocyte-endothelial cell adhesion, facilitates the downstream signaling, and may play a role in the development of artherosclerosis and rheumatoid arthritis. Accumulating evidence has demonstrated that VCAM1 exerts an anti-apoptotic effect in several tumor tissues such as ovarian cancer and breast cancer...

Over the past years, a growing number of studies have indicated that patients suffering from inflammatory bowel disease (IBD) have an increased risk of developing cardiovascular disease. Both are chronic inflammatory diseases and share certain pathophysiological mechanisms that may influence each other. High levels of cytokines, C-reactive protein (CRP), and homocysteine in IBD patients may lead to endothelial dysfunction, an early sign of atherosclerosis. IBD patients, in general, do not show the typical risk factors for cardiovascular disease but changes in lipid profiles similar to the ones seen in cardiovascular events have been reported recently...

In this study an in vitro model of simulated blood vessel injury was used to study the effects of bone marrow-derived mesenchymal stem cells (BMSCs) morphology and to detect vascular smooth muscle actin (SM α-actin) expression in the presence of adventitial fibroblasts. BMSCs from rats with DAPI-labeled nuclei were co-cultured with adventitial fibroblasts for 7 days, while BMSCs cultured alone served as controls. Cell morphology of BMSCs was assessed by laser confocal microscopy and SM α-actin or calponin expression in BMSCs was detected by immunofluorescence staining...

BACKGROUND: Apelin, and its receptor APJ, are a peptidic system playing a crucial role in vascular diseases. However, the role of apelin in atherogenesis and smooth muscle cell (SMC) proliferation remains unclear. We isolated 2 distinct SMC phenotypes from porcine coronary artery: spindle-shaped (S) and rhomboid (R). Biological features of R-SMCs (i.e. enhanced proliferative and migratory activities as well as poor level of differentiation) explain their capacity to accumulate into the intima...
