OBJECTIVE: Cardiovascular disease (CVD) caused by atherosclerosis remains a worldwide burden. Hydrogen sulfide is a promising new therapeutic avenue for the treatment of CVD, however reports show exogenous H2S has both vasodilator and vasoconstrictor effects depending on organ examined, and in vitro studies in animal models which are not resistant to developing atherosclerosis are limited. We sought to determine if rabbit arteries constricted or dilated to hydrogen sulfide. MATERIAL AND METHODS: The aorta, carotid, renal and iliac arteries were harvested from New Zealand White rabbits (n=4) and subjected to a concentration response curve to the fast H2S releaser NaHS...

Low levels of paraoxonase 1 (PON1) have been associated with the development of several pathological conditions, whereas high levels have been shown to be anti-atherosclerotic in mouse models. These findings suggest that PON1 could be a good surrogate biomarker. The other members of the family, namely PON2 and PON3, the role of which has been much less studied, deserve more attention. This paper provides a systematic review of current evidence concerning dietary supplements in that regard. Preliminary studies indicate that the response to dietary supplements may have a nutrigenetic aspect that will need to be considered in large population studies or in clinical trials...

Major reactive oxygen species (ROS)-producing systems in vascular wall include NADPH (reduced form of nicotinamide adenine dinucleotide phosphate) oxidase, xanthine oxidase, the mitochondrial electron transport chain, and uncoupled endothelial nitric oxide (NO) synthase. ROS at moderate concentrations have important signaling roles under physiological conditions. Excessive or sustained ROS production, however, when exceeding the available antioxidant defense systems, leads to oxidative stress. Animal studies have provided compelling evidence demonstrating the roles of vascular oxidative stress and NO in atherosclerosis...

INTRODUCTION: Aortic valve sclerosis has been shown to be associated with increased incidence, chances of developing myocardial infarction and even death. The epidemiological risk factors causing calcification of aortic valves have also been found to cause atherosclerosis. AIM: To analyse the epidemiological risk factors causing aortic valve sclerosis which have been studied in details and analysed to see whether they cause any significant increase in the incidence of cardiovascular events...

Phytoestrogens are estrogen-like compounds of plant origin. The pharmacological activities of phytoestrogens are predominantly due to their antioxidant, anti-inflammatory and lipid-lowering properties, which are mediated via the estrogen receptors (ERs): estrogen receptor alpha (ERα) and estrogen receptor beta (ERβ) and possibly G protein-coupled estrogen receptor 1 (GPER). Gypenoside XVII (GP-17) is a phytoestrogen that is widely used to prevent cardiovascular disease, including atherosclerosis, but the mechanism underlying these therapeutic effects is largely unclear...

Soy-leaf extracts exert their cardioprotective effects by inducing endothelium-dependent vasodilation in the arteries, and they favorably modulate the serum lipid profile. In this study, we investigated the atheroprotective effects of an ethanol extract of soy leaf (ESL) in human umbilical vein endothelial cells (HUVECs) and high-cholesterol diet (HCD)-fed low-density lipoprotein receptor deficient (LDLR-/-) mice. ESL induced the expression of Krüppel-like factor 2 (KLF2), an endothelial transcription factor, and endothelial nitric oxide synthase (eNOS), and suppressed the expression of vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1) through moderate inflammatory signal activation, not only in tumor necrosis factor-α (TNF-α)-stimulated HUVECs but also in 7-ketocholesterol (7-KC)-stimulated HUVECs...

RATIONALE: Chronic obstructive pulmonary disease (COPD) is the third-leading cause of death in the United States. Emphysema on computed tomography (CT) is associated with increased morbidity and mortality in patients with and without spirometrically defined COPD but no available medications target emphysema.  Transforming growth factor beta (TGF-β) and endothelial dysfunction are implicated in emphysema pathogenesis, and angiotensin II receptor blockers (ARB) inhibit TGF-β, improve endothelial function and restore airspace architecture in murine models...

Rheumatoid arthritis (RA) is an inflammatory circumstance, which has been associated with increased risk of cardiovascular disease (CVD). Although RA management has been promoted, mortality rate due to CVD remains remarkable. Approximately, 50% of premature death cases in RA are attributable to CVD. RA patients develop atherosclerosis in a greater amount than the general population. Moreover, atherosclerotic lesions develop rapidly in RA patients and might be more susceptible to rupture. The inflammatory condition of RA, such as cytokines, abnormally activated immune cells, play a role in the initiation, perpetuation and exacerbation of atherosclerosis...

Atherosclerosis is characterized by a proliferation of vascular smooth muscle cells (VSMCs) and their migration to the intima, which induces thickening of the intima itself, but the mechanism remains poorly understood. Low molecular weight heparin (LMWH) inhibits the proliferation of VSMCs. Previous studies have shown that a LMWH, parnaparin (PNP), acts on the processes of atherogenesis and atheroprogression in experimental animal models. The aim of this study was to investigate the involvement of oxidative stress, inflammation and VSMCs in the regulation of vascular wall homeostasis...

Sitosterolemia is a rare, autosomal recessively inherited disorder of lipid metabolism caused by mutations in the "ATP-binding cassette, subfamily G" member 5 and 8 proteins (encoded by the ABCG5 and ABCG8 genes, respectively), which play critical roles in the intestinal and biliary excretion of plant sterols. We report the clinical features and treatment outcomes of an 18-month-old Japanese girl with sitosterolemia, who presented with multiple linear and intertriginous xanthomas around the joint areas. Serum lipid analyses revealed elevated levels of total cholesterol (T-Chol: 866 mg/dL), low density lipoprotein-cholesterol (LDL-C: 679 mg/dL), and plant sterols (sitosterol: 24...

AIM: We investigated the relationships of serum uric acid levels with the progression of atherosclerosis in patients with peripheral arterial disease (PAD) after treatment. METHODS: Subjects were male patients diagnosed with PAD. Atherosclerosis at the common carotid artery was evaluated based on its intima-media thickness (IMT). Leg arterial flow was evaluated by measuring ankle-brachial index (ABI) and exercise-induced decrease in ABI. RESULTS: Among various risk factors including age, blood pressure, adiposity, estimated glomerular filtration rate, and blood lipid, blood glucose, uric acid, fibrinogen and C-reactive protein levels, only uric acid levels showed significant correlations with ABI [Pearson's correlation coefficient, -0...

Atherosclerosis is a leading cause of death worldwide; in addition to lipid dysfunction, chronic arterial wall inflammation is a key component of atherosclerosis. Techniques that target cell adhesion molecules, which are overexpressed during inflammation, are effective methods to detect and treat atherosclerosis. Specifically, research groups have identified vascular cell adhesion molecule-1, intercellular adhesion molecule-1, platelet endothelial cell adhesion molecule, and selectins (E-selectin and P-selectin) as correlated to atherogenesis...

Atherosclerosis is the primary cause of coronary heart disease (CHD), ischemic stroke, and peripheral arterial disease. Despite effective lipid-lowering therapies and prevention programs, atherosclerosis is still the leading cause of mortality in the United States. Moreover, the prevalence of CHD in developing countries worldwide is rapidly increasing at a rate expected to overtake those of cancer and diabetes. Prominent risk factors include the hardening of arteries and high levels of cholesterol, which lead to the initiation and progression of atherosclerosis...

Apoptosis plays a critical role in normal vascular development and atherosclerosis. However, high glucose has been reported to generate a certain level of ROS that can inhibit vascular smooth muscle cell (VSMC) apoptosis, with the underlying mechanism remaining unclear. In this study, a synthetic peptide AREGEM (Ala-Arg-Glu-Gly-Glu-Met) exhibited antioxidative effects and was used to investigate its function in VSMCs during hyperglycaemia. MTT assay results demonstrated that AREGEM significantly attenuated high glucose-induced VSMCs proliferation...

Hyperlipidemia is a group of disorders characterized by excessive lipids in the bloodstream. It is associated with the incidence of cardiovascular diseases and recognized as the most important factor underlying the occurrence of atherosclerosis. This study was conducted to investigate whether pretreatment with quercetin can protect against possible memory impairment and deterioration of the cholinergic system in hyperlipidemic rats. Animals were divided into ten groups (n=7): saline/control, saline/quercetin 5mg/kg, saline/quercetin 25mg/kg, saline/quercetin 50mg/kg, saline/simvastatin (0...

It is well established that atherosclerosis, the pathological basis of cardiovascular disease (CVD), begins in childhood and progresses steadily between the ages of 15 to 35 years. These adolescent and young adult years are also marked by significant physiological, psychological, and sociodemographic changes that impact both CVD risk factor development and CVD prevention and treatment strategies. In this review, we highlight the importance of the primordial prevention of CVD risk factors before they ever occur and the primary prevention of CVD by treating CVD risk factors in this age group...
