OBJECTIVE: Surgical treatment choice for coronary artery disease is coronary artery bypass grafting (CABG) surgery. Left internal mammary artery (LIMA) is frequently used as an arterial graft in CABG operations. Perioperative spasm of LIMA can result in increased morbidity and mortality. Pharmacological interventions are routinely used for prevention and treatment of LIMA spasm. In this study, we aimed to investigate the effects of carvedilol, an alpha- and beta-adrenergic receptor blocker, on responses to endogenous vasoconstrictors which play a role in graft spasm and the possible interaction between carvedilol and diltiazem/papaverine which are vasodilators commonly used in CABG surgery...

Platelet-derived microvesicles (pMVs) are small, heterogeneous vesicles released from platelet membranes as a result of activation. These microvesicles possess a wide range of properties, including prothrombotic, proatherogenic, proinflammatory, immunomodulatory, and even anticoagulant activity. The elevated release of these microvesicles has been observed in various metabolic, inflammatory, thrombotic, and vascular diseases, including ischemic heart disease, stroke, hypertension, diabetes, and connective tissue disease...

In vascular diseases, including hypertension and atherosclerosis, vascular endothelial dysfunction (VED) occurs secondary to altered function of endothelial nitric oxide synthase (eNOS). A novel redox regulated pathway was identified through which eNOS is uncoupled due to S-glutathionylation of critical cysteine residues, resulting in superoxide free radical formation instead of the vasodilator molecule, nitric oxide. In addition, the redox sensitive cofactor tetrahydrobiopterin, BH4, is also essential for eNOS coupling...

Uncoupling protein 2 (UCP2) is an inner mitochondrial membrane protein that belongs to the uncoupling protein family and plays an important role in lowering mitochondrial membrane potential and dissipating metabolic energy with prevention of oxidative stress accumulation. In the present article, we will review the evidence that UCP2, as a consequence of its roles within the mitochondria, represents a critical player in the predisposition to vascular disease development in both animal models and in humans, particularly in relation to obesity, diabetes, and hypertension...

The retention of lipoprotein particles in the intima, in particular to glycosaminoglycan side chains of proteoglycans, is a critical step in atherosclerosis initiation. Administration of chP3R99, a chimeric mouse/human monoclonal antibody inducing an anti-idiotypic network response against glycosaminoglycans was previously shown to prevent atherosclerotic lesion progression, yet its effect in the late-stage progression of lesions remains unknown. This study investigated the effect of chP3R99 at a late stage of disease development in apolipoprotein E-deficient mice and the vascular mechanisms involved...

Metabolic dysfunction is a well-established feature of Alzheimer's disease (AD), evidenced by brain glucose hypometabolism that can be observed potentially decades prior to the development of AD symptoms. Furthermore, there is mounting support for an association between metabolic disease and the development of AD and related dementias. Individuals with insulin resistance, type 2 diabetes mellitus (T2D), hyperlipidemia, obesity, or other metabolic disease may have increased risk for the development of AD and similar conditions, such as vascular dementia...

SIGNIFICANCE: Obesity and type 2 diabetes mellitus are increasing globally. There is also increasing associated complications, such as non-alcoholic fatty liver disease (NAFLD) and vascular complications of diabetes. There is currently no licensed treatment for NAFLD and no recent treatments for diabetic complications. New approaches are required, particularly addressing mechanism-based risk factors for health decline and disease progression. Recent advances: Dicarbonyl stress is the abnormal accumulation of reactive dicarbonyl metabolites such as methylglyoxal leading to cell and tissue dysfunction...

Tissue hypoxia has been proposed as an important factor in the pathophysiology of both chronic kidney disease and acute kidney injury, initiating and propagating a vicious cycle of tubular injury, vascular rarefaction, and fibrosis and thus exacerbation of hypoxia. Here, we critically evaluate this proposition by systematically reviewing the literature relevant to the following six questions: (1) Is kidney disease always associated with tissue hypoxia? (2) Does tissue hypoxia drive signaling cascades that lead to tissue damage and dysfunction? (3) Does tissue hypoxia per se lead to kidney disease? (4) Does tissue hypoxia precede pathology? (5) Does tissue hypoxia co-localize with pathology? (6) Does prevention of tissue hypoxia prevent kidney disease? We conclude that tissue hypoxia is a common feature of both acute kidney injury and chronic kidney disease...

BACKGROUND: Over 150 000 cases of suspected transient ischaemic attack (TIA) are referred to outpatient clinics in England each year. The majority of referrals are made by GPs. AIM: This study aimed to identify how many patients referred to a TIA clinic actually have TIA (that is, calculate the positive predictive value [PPV] of first-contact healthcare referral) and to record the alternative diagnoses in patients without TIA, in order to determine the optimal service model for patients with suspected TIA...

Risk assessment for transcatheter aortic valve implantation (TAVI) patients remains challenging, especially in elderly and high-risk candidates. Although several risk factors contribute to increased morbidity and mortality after TAVI, simple risk scores for routine use are lacking. Applying the CHA2DS2-VASC (congestive heart failure, hypertension, age ≥ 75 years, diabetes, prior stroke, vascular disease, age 65-74 years, sex [female] category) score as a novel risk stratification tool for conditions other than atrial fibrillation and stroke prevention has been previously examined; however, its usefulness in a population of patients with aortic stenosis after TAVI has not been established...

Neonatal liver disease is an important source of morbidity in the pediatric population. The manifestation of liver disease in young infants may be different than in older patients, and there are a number of diagnoses that are unique to this age group. Familiarity with these entities is important as imaging plays a key role in the diagnostic workup, and prompt diagnosis is necessary to prevent complications. This article reviews the spectrum of liver pathologies that can manifest in the first 6 months of life and is intended to educate the general radiologist who may be faced with interpretation of neonatal liver imaging...

Endothelial cells are a critical component of the bone marrow (BM) stromal network, which maintains and regulates hematopoietic cells. Vascular regeneration precedes, and is necessary for, successful hematopoietic stem cell (HSC) transplantation, the only cure for most hematopoietic diseases. Recent data suggest that mature hematopoietic cells regulate BM stromal-cell function. Whether a similar cross-talk regulates the BM vasculature is not known. Here we found that donor hematopoietic cells act on sinusoidal endothelial cells and induce host blood vessel and hematopoietic regeneration after BM transplantation in mice...

Endothelial progenitor cells (EPCs) contribute to neovasculogenesis and reendothelialization of damaged blood vessels to maintain the endothelium. Dysfunction of EPCs is implicated in the pathogenesis of vascular injury induced by homocysteine (Hcy). We aimed to investigate the role of Cyclin A in Hcy-induced EPCs dysfunction and explore its molecular mechanism. In this study, by treatment of EPCs with Hcy, we found that the expression of Cyclin A mRNA and protein were significantly downregulated in a dose-dependent manner...

Prostaglandin E2 (PGE2 ) increases cell proliferation and stimulates migratory and angiogenic abilities in prostate cancer cells. However, the effects of PGE2 on non-transformed prostate epithelial cells are unknown, despite the fact that PGE2 overproduction has been found in benign hyperplastic prostates. In the present work we studied the effects of PGE2 in immortalized, non-malignant prostate epithelial RWPE-1 cells and found that PGE2 increased cell proliferation, cell migration, and production of vascular endothelial growth factor-A, and activated in vitro angiogenesis...

Cell-cycle dysfunction and faulty DNA repair are closely intertwined pathobiological processes that may contribute to several neurodegenerative disorders. CDKN1A interacting zinc finger protein 1 (CIZ1) plays a critical role in DNA replication and cell-cycle progression at the G1/S checkpoint. Germline or somatic variants in CIZ1 have been linked to several neural and extra-neural diseases. Recently, we showed that germline knockout of Ciz1 is associated with motor and hematological abnormalities in young adult mice...

Objective An increasing emphasis on preventive medicine has been supported by the recent reforms in United States health care system. Majority of the patients seen in vascular surgery clinics are elderly with more extensive medical comorbidities compared to the general population. Thus, these patients would be expected at higher risk for common malignant pathologies such as colon, breast and cervical cancer, and nonmalignant diseases such as diabetic retinopathy. This study looked at the screening compliance of vascular patients compared to data provided by Centers for Disease Control on the national and state levels...

Cerebral stroke is a kind of acute cerebrovascular disease with high incidence, morbidity and disability. Treatments against various types of cerebral stroke are limited at preventive measurements due to the lack of effective therapeutic method. The present study aimed to investigate the protective effect of cryptotanshinone (CPT) on cerebral stroke, and investigate the possible mechanism involved in order to develop a novel therapy against stoke. The phosphoinositide 3‑kinase membrane translocation of cerebral stroke rats pretreated with CPT at various concentrations were measured, as well as the phosphorylation of protein kinase B (AKT) and endothelial nitric oxide synthase (eNOS)...
