Stiffening of large elastic arteries with age increases the risk of cardiovascular diseases (CVD), but the underlying mechanisms are incompletely understood. We investigated the role of mitochondrial quality control (QC, i.e., mitophagy and biogenesis) in arterial stiffening with aging. In C57BL6 mice, aging was associated with impaired aortic expression of ...

Pulmonary arterial hypertension (PAH) is a vascular remodeling disease of the lungs resulting in heart failure and premature death. Although, until recently, it was thought that PAH pathology is restricted to pulmonary arteries, several extrapulmonary organs are also affected. The realization that these tissues share a common metabolic abnormality (i.e., ...

Our aim was to investigate the role played by endothelial nitric oxide (NO) during acute vascular response to hypoxia, as a modulator of both vascular tone (through guanylate cyclase (sGC) activation) and mitochondrial O2 consumption (through competitive inhibition of cytochrome-c-oxydase (CcO)). Organ bath experiments were performed and O2 consumption (Clark ...

BACKGROUND: Evidence suggestive of endoplasmic reticulum (ER) stress in the pulmonary arteries (PA) of patients with pulmonary arterial hypertension (PAH) has been described for decades but has never been therapeutically targeted. ER stress is a feature of many conditions associated with PAH like hypoxia, inflammation or loss-of-function mutations. ER stress ...

Cytomegalovirus (CMV) infections are associated with vascular diseases in the human population. We have previously shown vascular dysfunction in systemic and uterine arteries dissected from non-pregnant (NP) mouse CMV (mCMV)-infected mice that was further impaired during late pregnancy (LP). CMV attachment alone through glycoprotein B (GB) can generate signals that ...

An imbalance between glutamate and glycine signalling may contribute to sepsis-associated encephalopathy by causing neuronal excitotoxicity. In this study, we therefore investigated the transcerebral exchange kinetics of glutamate and glycine in a human-experimental model of systemic inflammation. Cerebral blood flow (CBF) and arterial to jugular venous concentration differences of glutamate ...

Inhaled NO (iNO) is used to treat pulmonary hypertension and is being investigated for prevention of bronchopulmonary dysplasia in neonates. Extrapulmonary effects of iNO are widely recognized, but the underlying chemistry and pharmacology are poorly understood. Growing evidence suggests that, in addition to diffusion of NO, NO-derived nitrosants can react ...

The lectin-like oxidised LDL receptor-1 (OLR1) gene encodes a scavenger receptor implicated in the pathogenesis of atherosclerosis. Although functional roles have been suggested for two variants, epidemiological studies on OLR1 have been inconsistent. We tested the association between the non-synonymous substitution K167N (rs11053646) and intima media thickness of the common ...

Prior to the eighteenth century, the vertebral venous plexus (VVP) received scant mention, had no clinical relevance and was largely ignored by anatomists, most likely due to its location and non - distensible nature. Gilbert Breschet in 1819 provided the first detailed anatomical description of the VVP, describing it as ...

The author presents the case of a child with bilateral thumb hypoplasia. Pollicization of the left index finger with grade 4 thumb hypoplasia was attempted and abandoned, apparently because of anomalous vascular anatomy. A secondary procedure identified a substantial second dorsal metacarpal artery that connected with a palmar-ulnar digital vessel ...

Coronary artery fistulas are uncommon anomalies. They occur in 0.1-0.2% of patients undergoing coronary arteriography. The origin of the fistulas is the right coronary artery followed by the left anterior descending and lastly by the circumflex artery (17%). Termination into the right heart side occurs in 90% of cases. Termination ...

Neointimal hyperplasia (NIH) and impaired dilatation are important contributors to arteriovenous fistula (AVF) failure. It is unclear whether chronic kidney disease (CKD) itself causes adverse remodeling in arterialized veins. Here we determined if CKD specifically triggers adverse effects on vascular remodeling and assessed whether these changes affect the function of ...
