Dysfunction of vascular endothelial cells (VECs), such as increased apoptosis and diminished migration, is closely connected with most cardiovascular diseases and angiogenesis-related events. LncRNAs have been involved in regulation of many pathological processes, but their roles in vascular endothelial function are hardly underreported. Here, we explore the role of a intergenic lncRNA named linc00152 in the apoptosis and migration of VECs. We found that linc00152 was downregulated in human umbilical vein VECs (HUVECs) in a dose- and time-dependent manner following treatment with oxLDL, which is a typical proinflammatory factor in the initiation and progression of vascular endothelial dysfunction...

Gabriele E Lang, Stefan J Lang
Retinal artery occlusions are acute vascular diseases. Very often they are caused by an embolisation. Rarely a thrombosis is caused by an arteriitis. In the acute phase diagnosis in most of the cases can be made by ophthalmoscopy due to the whitish retinal edema and in central retinal artery occlusion the cherry red spot. Difficulties in making the diagnosis can occur in the chronic stage, especially after reperfusion of the retinal vessels, when the fundus colour returned to normal again. Several diagnostic procedures help to make the diagnosis...

Chronic kidney disease (CKD) is a great risk factor for cardiovascular disease events and mortality, and progressively develops to the clinical phenotype called "uremic cardiomyopathy". We describe here an experimental CKD mouse model, named 5/6(th) partial nephrectomy (PNx) with pole ligation, which developed uremic cardiomyopathy at four weeks post-surgery. This PNx model was performed by a two-step surgery. In step-one surgery, both poles of the left kidney were ligated. In step-two surgery, which was performed 7 days after the step-one surgery, the right kidney was removed...

REVIEW
Hong Xu, Juan J Carrero
This review provides an overview of insulin resistance (IR) in patients with chronic kidney disease (CKD). IR is a pathological state in which target tissues fail to respond normally to insulin. IR is understood as a consequence of CKD and its prevalence rises particularly in advanced CKD stages. Mechanisms leading to IR are complex and multifactorial, involving post-receptor signaling defects, unhealthy lifestyles, metabolic acidosis, inflammation, oxidative stress, vitamin D deficiency, anemia, and uremic toxicity, as shown by human and experimental studies over the last 30 years...

Cyclooxygenase-derived thromboxane (TxA2) and prostacyclin (PGI2) regulate atherogenesis in preclinical models. However, the relationship between TxA2 and PGI2 biosynthesis, vascular inflammation, and atherosclerotic cardiovascular disease (ASCVD) progression in humans remains unclear. The association between stable urine metabolites of thromboxane (TxA2-M) and prostacyclin (PGI2-M), circulating levels of cellular adhesion molecules (CAMs: E-selectin, P-selectin), chemokines and C-reactive protein, and the incidence of major adverse cardiovascular events (MACE) were evaluated in 120 patients with stable ASCVD on aspirin therapy...

Polycystic ovary syndrome (PCOS) is a very prevalent endocrine disease affecting reproductive women. Clinically, patients with this disorder are more vulnerable to develop type 2 diabetes mellitus (T2DM), cardiovascular events, as well as metabolic syndrome (MetS). To date, the molecular mechanism underlying PCOS remains largely unknown. Previously, we showed that mitochondrial dysfunction caused by mitochondrial DNA (mtDNA) mutation was an important cause for PCOS. In the current study, we described the clinical and biochemical features of a three-generation pedigree with maternally transmitted MetS, combined with PCOS...

OBJECTIVES: Sleep, which comprises of rapid eye movement (REM) and non-REM stages 1-3 (N1-N3), is a natural occurring state of decreased arousal that is crucial for normal cardiovascular, immune and cognitive function. The principal sedative drugs produce electroencephalogram beta oscillations, which have been associated with neurocognitive dysfunction. Pharmacological induction of altered arousal states that neurophysiologically approximate natural sleep, termed biomimetic sleep, may eliminate drug-induced neurocognitive dysfunction...

BACKGROUND: Alirocumab, a fully human monoclonal antibody to proprotein convertase subtilisin/kexin type 9, has been shown to provide significant reductions in low-density lipoprotein cholesterol (LDL-C). Data about its efficacy and safety in patients from South Korea and Taiwan are limited. OBJECTIVE: ODYSSEY KT assessed the efficacy and safety of alirocumab in patients from South Korea and Taiwan. METHODS: Patients with hypercholesterolemia at high cardiovascular risk who were on maximally tolerated statin were randomized (1:1) to alirocumab (75 mg every 2 weeks, with dose increase to 150 mg every 2 weeks at week 12 if LDL-C ≥70 mg/dL at week 8) or placebo for 24 weeks...

Pregnancy is characterized by a blunted pressor response to angiotensin II that is progressively lost during preeclampsia complicated pregnancies. Renin angiotensin system (RAS) plays a pivotal role in cardiovascular and renal function but its role in normal and pathological pregnancy is far from being clarified. It is not as clear if hypertension and particularly pregnancy-induced hypertension as the initial event, can trigger some of the metabolic syndrome components, and if these changes are angiotensin II mediated...

Colorectal cancer is a worldwide public health problem. Aspirin has been identified as a protective factor against the apparition of colorectal cancer. There are several mechanisms about the actions by aspirin on colorectal tumorogenesis. These are not perfectly known nowadays. On one hand, there are direct mechanisms on colorectal mucosa, on the other hand there are indirect mechanisms through platelet functions. Aspirin also plays a role by its anti-inflammatory action and the stimulation of antitumor immunity...

OBJECTIVES: The authors sought to explore the comparative clinical efficacy of different imaging modalities for guiding percutaneous coronary interventions (PCI). BACKGROUND: Coronary angiography (CA) is the standard imaging modality for intraprocedural guidance of PCI. Intracoronary imaging techniques, including intravascular ultrasound (IVUS) and optical coherence tomography (OCT), can overcome some limitations of CA. METHODS: Comprehensive hierarchical Bayesian network meta-analysis of randomized clinical trials and adjusted observational studies comparing clinical outcomes of PCI with stent implantation guided by CA, IVUS, or OCT...

Iron overload was considered rare in hemodialysis patients until recently, but its clinical frequency is now increasingly recognized. The liver is the main site of iron storage and the liver iron concentration (LIC) is closely correlated with total iron stores in patients with secondary hemosiderosis and genetic hemochromatosis. Magnetic resonance imaging (MRI) is now the gold standard method for estimating and monitoring LIC. Studies of LIC in hemodialysis patients by magnetic susceptometry thirteen years ago and recently by quantitative MRI have demonstrated a relation between the risk of iron overload and the use of intravenous (IV) iron products prescribed at doses determined by the iron biomarker cutoffs contained in current anemia management guidelines...

Kawasaki disease (KD) is an acute, self-limited vasculitis affecting young children. It can result in coronary artery abnormalities in a significant proportion of patients, especially if the diagnosis is missed or treatment gets delayed. Echocardiography is the imaging modality of choice for detection of coronary artery abnormalities and assessment of myocardial function. It is also useful for characterization and risk stratification of patients with KD. Echocardiography should be performed at the time of diagnosis and then again at 1-2 weeks and 4-6 weeks after treatment, for uncomplicated cases who do not have significant coronary artery involvement...
