Early atherosclerosis features functional and structural changes in the endothelial barrier function that affect the traffic of molecules and solutes between the vessel lumen and the vascular wall. Such changes are mechanistically related to the development of atherosclerosis.Proatherogenic stimuli and cardiovascular risk factors, such as dyslipidemias, diabetes, obesity, and smoking, all increase endothelial permeability sharing a common signalling denominator: an imbalance in the production/disposal of reactive oxygen species (ROS), broadly termed oxidative stress...

BACKGROUND: Carotid intima-media thickness (cIMT) is a significant early prediction signal for preclinical atherosclerosis. Plasma homocysteine (Hcy) level is an independent risk factor for cardiovascular diseases. Pulse wave velocity (PWV), an index of arterial stiffness (AS), has showed its value in the evaluation of AS in vascular-related diseases. The data regarding the relationships between cIMT and other indices of vascular damage are limited and partly controversial. We aim to investigate the relationships between cIMT and other indices of vascular damage such as Hcy and carotid femoral PWV (CF-PWV)...

BACKGROUND: Endothelial progenitor cells (EPCs) repair damaged vascular endothelium and low circulating EPC levels have been associated with cardiovascular disease (CVD). CD34+/KDR+ EPCs are commonly reported in literature and CD34+/CD133+/KDR+ EPCs are rare in circulation but highly specific for endothelial lineage. HIV-infected (HIV+) adults have chronic inflammation and increased CVD risk, but the relationship between CVD, vascular inflammation and EPCs in HIV remains unclear. METHODS: In a pilot study, EPCs were measured in 57 HIV+ men (≧50 years old, HIV-1 RNA <50 copies/mL on ART) by real-time flow cytometry using cellular immaturity (CD34 and/or CD133) and endothelial commitment (KDR) markers...

Abdominal aortic aneurysm (AAA) is a fatal disease that is associated with chronic inflammation in the vessel wall. Cortistatin is implicated in inflammation, vascular smooth muscle cell migration and other cardiovascular pathologies. But, the hypothetical effect of cortistatin on AAA remains uncertain. We investigated the effect of cortistatin administration to angiotensin (Ang) II-induced AAA formation in apolipoprotein E deficient (Apoe-/-) mice. We showed that cortistatin administration significantly suppresses incidence and severity of AAA in Apoe-/- mice...

OBJECTIVE: It has long been known that hydroxymethylglutaryl-coenzyme A reductase inhibitors (statins) broadly reduce cardiovascular events in patients with peripheral vascular disease. It was the goal of this study to determine whether there is an association between statin therapy and primary patency after stenting of superficial femoral and popliteal arteries. METHODS: The records of all patients undergoing primary nitinol stenting of the femoral and popliteal arteries at a single institution and by a single surgeon during a 10-year period were reviewed...

Effective pharmaceutical treatments for age-related cognitive decline have proved elusive. There is, however, compelling evidence that nutritional status and supplementation could play crucial roles in modifying the expression of cognitive change through the lifespan. Subjective memory impairment and mild cognitive impairment can be harbingers of dementia but this is by no means inevitable. Neurocognitive change is influenced by a variety of processes, many of which are involved in other aspects of systemic health, including cardiovascular function...

Cardiovascular thrombosis is rare in children and usually occurs in the presence of predisposing conditions, such as indwelling vascular catheters, tumors, aneurysms, ventricular dysfunction, or after surgery. Clots can occur in the cardiac chambers, arteries or veins, or inside conduits. Detection of thrombi is feasible with a variety of magnetic resonance imaging (MRI) techniques, including unenhanced methods but also contrast-enhanced MR angiography. In this essay we illustrate the MRI appearance of cardiovascular thrombosis in children and suggest an imaging protocol based on our clinical experience...

BACKGROUND/AIMS: Post-transplant hypertension is highly prevalent in renal transplant recipients and is a risk factor for graft loss, cardiovascular disease and death. Glucocorticoid is used to prevent rejection, but simultaneously increases the risk of post-transplant hypertension. The glucocorticoid-induced transcript 1 (GLCCI1) promoter polymorphism (rs37972) has been reported to be associated with response to glucocorticoid therapy in asthma. We therefore examined the association between GLCCI1 promoter polymorphism and post-transplant hypertension in renal transplant recipients...

Cardiovascular toxicity of lead (Pb) manifests primarily as an effect on blood pressure and eventual increased risk of atherosclerosis and cardiovascular events. Therefore, we investigated vascular inflammatory biomarkers and cardiovascular effects of Pb-exposed children. A total of 590 children (3-7 years old) were recruited from Guiyu (n = 337), an electronic waste (e-waste)-exposed group, and Haojiang (n = 253), a reference group, from November to December 2016. We measured child blood Pb levels (BPbs), and systolic and diastolic blood pressure...

Vasoplegic syndrome, characterized by low systemic vascular resistance and hypotension in the presence of normal or supranormal cardiac function, is a frequent complication of cardiovascular surgery. It is associated with a diffuse systemic inflammatory response and is mediated largely through cellular hyperpolarization, high levels of inducible nitric oxide, and a relative vasopressin deficiency. Cardiopulmonary bypass is a particularly strong precipitant of the vasoplegic syndrome, largely due to its association with nitric oxide production and severe vasopressin deficiency...

AIM: Although many approaches to esophageal replacement have been investigated, these efforts have thus far only met limited success. In-body-tissue-engineered connective tissue tubes have been reported to be effective as vascular replacement grafts. The aim of this study was to investigate the usefulness of an In-body-tissue-engineered collagenous connective tissue membrane, "Biosheet", as a novel esophageal scaffold in a beagle model. METHODS: We prepared Biosheets by embedding specially designed molds into subcutaneous pouches in beagles...

Pulmonary hypertension (PH) frequently occurs in infants with bronchopulmonary dysplasia (BPD), causing increased mortality and right ventricular (RV) dysfunction that persists into adulthood. A first step in developing better therapeutic options is identifying and characterizing an appropriate animal model. Previously, we characterized the short-term morbidities of a model in which C57BL/6J wild-type (WT) mice were exposed to 70% O2 (hyperoxia) during the neonatal period. Here, we aimed to determine the long-term morbidities using lung morphometry, echocardiography (Echo), and cardiac magnetic resonance imaging (cMRI)...

Atherosclerosis accounts for numerous cardiovascular diseases, and cytokines have a critical role in acceleration or suppression of disease. Salusin-α presents a new class of bioactive peptides that can have anti-atherogenic properties. Therefore, the effects of salusin-α on the expression of some pro- and anti-inflammatory cytokines and on TNF-α-induced inflammatory responses in human umbilical vein endothelial cells (HUVECs) were examined. The involvement of the NF-κB pathway in effects of salusin-α in HUVECs was checked using Bay 11-7082 as an NF-κB inhibitor...

Phthalates are one of the main constituents of plastic, reaching up to 40% of the total plastic weight, and their main function is to impart flexibility/elasticity to polymers that would otherwise be rigid. Phthalates are known as endocrine disruptors, since they can interfere with hormone homeostasis. Regarding the cardiovascular system, it was already shown the effects of di-(2-ethylhexyl) phthalate (DEHP) exposure with significant changes in several calcium-handling proteins and an increase in the blood pressure of mice offspring, suggesting that DEHP leads to vasocontraction...

Development of a closed circulatory system requires that large arteries adapt to the mechanical demands of high, pulsatile pressure. Elastin and collagen uniquely address these design criteria in the low and high stress regimes, resulting in a nonlinear mechanical response. Elastin is the core component of elastic fibers, which provide the artery wall with energy storage and recoil. The integrity of the elastic fiber network is affected by component insufficiency or disorganization, leading to an array of vascular pathologies and compromised mechanical behavior...

Cardiovascular (CV) health has emerged as an important consideration in patients with chronic myeloid leukemia (CML) because of improved prognosis. Indeed, the success of BCR-ABL1 tyrosine kinase inhibitors (TKIs) has increased the focus on survivorship and late toxicity in oncological care. Survivorship issues in this population include CV disease prevention, given its prevalence in the general population. The introduction of BCR-ABL1 TKIs represented a unique concept of indefinite cancer therapy, only recently evolving to include "treatment-free remission...

Several studies have demonstrated zebrafish as a useful high-throughput in-vivo model to study the effects of cigarette smoke on early development. It has been shown previously that exposure of zebrafish to cigarette smoke total particulate matter (TPM) leads to several adverse physiological aberrations, including heart deformities and improper angiogenesis. Consequently, this study investigated the effects of TPM on cardiovascular development in zebrafish that were exposed to increasing concentrations of TPM based upon nicotine content from 6h post fertilization (hpf) up to 72hpf...

Exposure to psychosocial stress is a risk factor for cardiovascular disease, including vascular aging and regeneration. Dipeptidyl peptidase-4 (DPP-4) exerts many physiological and pharmacological functions by regulating its extremely abundant substrates [e.g., glucagon-like peptide-1 (GLP-1), stromal cell-derived factor-1α/ C-X-C chemokine receptor type-4, etc.]. Over the past decade, emerging data revealed unexpected roles for DPP-4 and GLP-1 in intracellular signaling, oxidative stress production, lipid metabolism, cell apoptosis, immune activation, insulin resistance, and inflammation...

- Platelet aggregation inhibitors, also known as antiplatelet therapy (APT), are prescribed for the prevention of secondary cardiovascular events (CVE) after endovascular revascularization procedures.- Platelet aggregation inhibitors are not equally effective in all patients. The phenomenon of high residual platelet reactivity despite APT is called 'high on-treatment platelet reactivity' (HTPR); it bears an increased risk of secondary CVE.- Platelet function tests (PFT) can be used to diagnose HTPR. There are various tests available; of those, light transmission aggregometry (LTA) is considered the gold standard...
