Systemic fibrinogen and neopterin are related to inflammation. We investigated the prognostic utility and possible interactions of these biomarkers in stable coronary artery disease (SCAD) patients undergoing coronary angiography. We included 3,545 patients with suspected stable angina with a median follow-up of 7.3 and 10.2 years for incident acute myocardial infarction (AMI) and all-cause mortality, respectively. Prospective associations were explored by Cox regression. Potential effect modifications were investigated according to strata of fibrinogen, neopterin or high-sensitivity troponin T (hsTnT) below and above the median, as well as gender and smoking habits...

Introduction: Le Fort I and sagittal split ramus osteotomies are the most commonly performed orthognathic surgery procedures on the maxilla and mandible, respectively. Techniques: Despite progress in the techniques, these procedures may still be associated with morbidity, expressed as inflammation, inadequate bony union, periodontal damages or in extreme cases even total bone loss. Discussion: Through a comprehensive review of the literature, the influences of maxillary and mandibular surgery on Pulpal Blood Flow (PBF), pulp sensitivity and pulp vitality are examined...

Resolvins are innate, immune responsive, bioactive mediators generated after myocardial infarction (MI) to resolve inflammation. The MI-induced bidirectional interaction between progressive left ventricle (LV) remodeling and kidney dysfunction is known to advance cardiorenal syndrome (CRS). Whether resolvins limit MI-induced cardiorenal inflammation is unclear. Thus, to define the role of exogenous resolvin D (RvD)-1 in post-MI CRS, we subjected 8-12-wk-old male C57BL/6 mice to coronary artery ligation. RvD1 was injected 3 h after MI...

Immune activation and inflammation participate in the progression of chronic heart failure (CHF). Th17 cells and CD4+CD25+ regulatory T (Treg) cells both come from naive Th cells and share reciprocal development pathways but exhibit opposite effects. We hypothesized that the Th17/Treg balance was impaired in patients with CHF, and exercise can improve it. Rats with ischemic cardiomyopathy were prepared by ligaturing the left anterior descending branch of the left coronary artery. Rats in training group were trained with treadmill; Th17 cells increased significantly while Treg cells significantly decreased in s by flow cytometry, and the peripheral blood level of IL-6, IL-17, and TNF-α was obviously elevated by ELISA assay...

The effect of circulating biomarkers in predicting coronary artery disease (CAD) is not fully elucidated. This study aimed to determine the relationship with CAD and the predictive capacity of nine biomarkers of inflammation (TNF-α, IL-10, IL-6, MCP-1, CRP), oxidation (GHS-Px), and metabolism (adiponectin, leptin, and insulin). This was a case-cohort study, within the REGICOR population-cohorts (North-Eastern Spain), of 105 CAD cases and 638 individuals randomly selected from a cohort of 5,404 participants aged 35-74 years (mean follow-up = 6...

BACKGROUND: There are inconsistent data about the role of serum phospholipid fatty acid composition in patients with type 2 diabetes (T2DM) and atherosclerotic cardiovascular disease (ASCVD). The aim of the study was to investigate the relationship between serum phospholipid fatty acid composition, systemic low-grade inflammation, and glycemic control in high-risk T2DM patients. METHODS: Seventy-four patients (26% women, mean age 65.6 ± 6.8 years) with T2DM (median diabetes duration 10 years) and documented ASCVD (74 with coronary artery disease, 26 with peripheral arterial disease) were enrolled in the study...

To determine whether arterial responsiveness is impaired among patients with gout, and whether arterial responsiveness inversely correlates with serum urate and inflammatory measures. This is a cross-sectional study of untreated gout subjects (n = 34) and non-gout healthy controls (n = 64). High-resolution dynamic ultrasound-measured flow-mediated dilation (FMD) and nitroglycerin-mediated dilation (NMD) assessed endothelium-dependent and endothelium-independent arterial responsiveness respectively. Serum urate (sUA) and high-sensitivity C-reactive protein (hsCRP) were measured in the gout group, and correlated with FMD and NMD responses...

Genetic defects in bone morphogenetic protein type-II receptor (BMPRII) signalling and inflammation contribute to the pathogenesis of pulmonary arterial hypertension (PAH). The receptor is activated by BMP ligands, which also enhance BMPR2 transcription. A small molecule BMP upregulator with selectivity on vascular endothelium would represent a desirable therapeutic intervention for PAH.We assayed compounds identified in the screening of BMP2 upregulators for their ability to increase expression of Inhibitor of DNA binding 1 (Id1), using a dual reporter driven specifically in human embryonic stem cell (hESC)-derived endothelial cells (ECs)...

Heart failure and related morbidity and mortality are increasing at an alarming rate, in large part, because of increases in aging, obesity, and diabetes mellitus. The clinical outcomes associated with heart failure are considerably worse for patients with diabetes mellitus than for those without diabetes mellitus. In people with diabetes mellitus, the presence of myocardial dysfunction in the absence of overt clinical coronary artery disease, valvular disease, and other conventional cardiovascular risk factors, such as hypertension and dyslipidemia, has led to the descriptive terminology, diabetic cardiomyopathy...

Mesenchymal stem cells (MSC) have been experimentally used for kidney repair, but modest retention limits their efficacy. Cell-surface coating allows modulating MSC homing and interaction with target cells. We coated mouse adipose tissue-derived MSC with antibodies directed against kidney injury molecule-1 (ab-KIM1), which is upregulated in injured kidneys, and tested the hypothesis that this would enhance their therapeutic effects in ischemic kidney injury. Untreated MSC, ab-KIM1-coated MSC (KIM-MSC), or vehicle, were injected systemically into the carotid artery of 2-kidneys, 1-clip mice 2 weeks after surgery...

PURPOSE OF REVIEW: Atherosclerosis is an inflammatory disorder of the arterial wall, in which several players contribute to the onset and progression of the disease. Besides the well-established role of lipids, specifically cholesterol, and immune cell activation, new insights on the molecular mechanisms underlying the atherogenic process have emerged. RECENT FINDINGS: Meta-inflammation, a condition of low-grade immune response caused by metabolic dysregulation, immunological memory of innate immune cells (referred to as "trained immunity"), cholesterol homeostasis in dendritic cells, and immunometabolism, i...

BACKGROUND: Obesity contributes significantly to the development and evolution of cardiovascular disease (CVD) which is believed to be mediated by oxidative stress, inflammation and endothelial dysfunction. However, the vascular health of metabolically obese and normal weight (MONW) individuals is not completely comprehended. OBJECTIVES: The purpose of our study was to evaluate vascular function on the basis of a high fat diet (HFD)-MONW rabbit model. SUBJECTS: Twenty four male rabbits were randomly assigned to receive either a regular diet (CD, n = 12) or a high-fat diet (18% extra fat on the regular diet, HFD, n = 12) for 6 weeks...

Atherosclerosis is a dynamic and progressive inflammatory process in the intimal layer of large and medium-sized arteries, and it is the major contributor to the atherosclerotic cardiovascular disease (ACVD), the leading cause of death worldwide. In an atherosclerotic plaque, phagocytosis of apoptotic cells occurs through an intricate process designated efferocytosis. Defective efferocytosis has emerged as a causal factor in the etiopathogenesis of atherosclerosis and its progression into overt ACVD. Both specialized phagocytes (macrophages and dendritic cells) and non-specialized cells with phagocytic capabilities (smooth muscle and endothelial cells) are involved in the efferocytotic process...

Cardiovascular diseases (CVDs) are currently among the leading causes of death worldwide. Platelet aggregation is a key cellular component of arterial thrombi and major cause of CVDs. Protease-activated receptors (PARs), including PAR1, PAR2, PAR3 and PAR4, fall within a subfamily of seven-transmembrane G-protein-coupled receptors (GPCR). Human platelets express PAR1 and PAR4, which contribute to the signaling transduction processes. In association with CVDs, PAR4 not only contributes to platelet activation but also is a modulator of cellular responses that serve as hallmarks of inflammation...

Thrombospondin-1 (TSP-1), a matricellular protein and one of the first endogenous anti-angiogenic molecules identified, has long been considered a potent modulator of human diseases. While the therapeutic effect of TSP-1 to suppress cancer was investigated in both research and clinical settings, the mechanisms of how TSP-1 is regulated in cancer remain elusive, and the scientific answers to the question of whether TSP-1 expressions can be utilized as diagnostic or prognostic marker for patients with cancer are largely inconsistent...

Acute respiratory distress syndrome (ARDS) mainly involves acute respiratory failure. In addition to this affected patients feel progressive arterial hypoxemia, dyspnea, and a marked increase in the work of breathing. The only clinical solution for the above pathological state is ventilation. Mechanical ventilation is necessary to support life in ARDs but it itself worsen lung injury and the term is known clinically as 'ventilation induced lung injury' (VILI). At the cellular level, respiratory epithelial cells are subjected to cyclic stretch, i...
