Abstract Impaired cerebrovascular function contributes to the genesis of age‐related cognitive decline. In this study, hypothesis is tested that impairments in neurovascular coupling (NVC) responses and brain network predict dysfunction older adults. Cerebromicrovascular working memory healthy young ( n = 21, 33.2±7.0 years) aged 30, 75.9±6.9 participants are assessed. To determine NVC functional connectivity (FC) during a (n‐back) paradigm, oxy‐ deoxyhemoglobin concentration changes from frontal cortex using near‐infrared spectroscopy recorded. significantly impaired 2‐back task participants, while networks characterized by higher local global connection strength, dynamic FC p < 0.05). Both increased correlate with decline accuracy task. These findings suggest task‐related states adults require stronger connections compensate for attenuated associated load.

Nitric oxide (NO) plays an important and diverse signalling role in the cardiovascular system, contributing to regulation of vascular tone, endothelial function, myocardial haemostasis, thrombosis, amongst many other roles. NO is synthesised through nitric synthase (NOS)-dependent L-arginine-NO pathway, as well nitrate-nitrite-NO pathway. The three isoforms NOS, namely neuronal (NOS1), inducible (NOS2), (NOS3), have different localisation functions human body, are consequently thought differing pathophysiological Furthermore, we continue develop a deepened understanding roles NOS disease, possibility therapeutically modulating activity has emerged. Indeed, impaired (or dysfunctional), overactive dysregulated) attractive therapeutic targets disease. This review aims describe recent advances elucidating physiological within mechanisms dysfunctional dysregulated We then discuss modulation target development novel therapeutics.

The endothelium is a monocellular layer covering the inner surface of blood vessels. It maintains vascular homeostasis regulating tone and permeability exerts anti-inflammatory, antioxidant, anti-proliferative, anti-thrombotic functions. When exposed to detrimental stimuli including hyperglycemia, hyperlipidemia, neurohormonal imbalance, different biological pathways are activated leading oxidative stress, endothelial dysfunction, increased secretion adipokines, cytokines, endothelin-1, fibroblast growth factor, reduced nitric oxide production, eventually loss integrity. Endothelial dysfunction has emerged as hallmark dysmetabolic impairment contributes effects on cardiac metabolism diastolic development cardiovascular diseases heart failure. Different biomarkers have been proposed predict in order identify microvascular macrovascular damage atherosclerosis, particularly metabolic disorders. also plays an important role severe COVID-19 complications patients after SARS-CoV-2 infection. In this review, we will discuss mechanisms involved dysregulation context cardiometabolic well available promising clinical practice.

Venous thromboembolism, characterized by deep vein thrombosis and pulmonary embolism, is the third cardiovascular disease in world. Deep occurs when a blood clot forms areas of impaired flow, it significantly affected environmental factors. Local hypoxia, caused venous stasis, plays critical role under normal conditions, this effect intensified P o 2 decreases, such as during air travel or high-altitude exposure. The lower oxygen levels reduced pressure at high altitudes further contribute to development. These conditions increase pro-coagulant activity neutrophils, platelets, red cells, which interact on surface activated endothelial promoting formation. Understanding mechanisms involved thrombus formation reduced, with without reduction, crucial for preventing development thromboembolisms identifying innovative therapeutic targets. This literature review explores related discusses consequences induced disturbances.

Abstract Preserving the balance of metabolic processes in endothelial cells (ECs) and vascular smooth muscle (VSMCs), is crucial for optimal function integrity. ECs are metabolically active depend on aerobic glycolysis to efficiently produce energy their essential functions, which include regulating tone. Impaired EC metabolism linked damage, increased permeability inflammation. Metabolic alterations VSMCs also contribute dysfunction atherosclerosis hypertension. Magnesium (Mg 2+ ) second most abundant intracellular divalent cation influences molecular that regulate function, including vasodilation, vasoconstriction, release vasoactive substances.

Growing evidence indicates important role transient receptor potential melastatin‐subfamily member 7 (TRPM7) channel regulation VSMCs. In vasculature, TRPM7 deficiency leads impaired contraction, phenotypic switching VSMCs, fibrosis, characterize phenotype Here we provide a comprehensive overview TRPM7/Mg how VSMC such as glucose homeostasis, redox regulation, phosphoinositide signaling, mineral metabolism.

The endothelium is composed of a monolayer endothelial cells, lining the interior surface blood and lymphatic vessels. Endothelial cells display important homeostatic functions, since they are able to respond humoral hemodynamic stimuli. Thus, dysfunction has been proposed as key early pathogenic mechanism in many clinical conditions. Given relevant repercussions on cardiovascular risk, complex interplay between systemic arterial hypertension matter study recent years. Numerous articles have published this issue, all which contribute providing an interesting insight into molecular mechanisms its role biomarker inflammation, oxidative stress, vascular disease. prognostic therapeutic implications also analyzed setting, with new findings potential applications practice future research. aim review summarize pathophysiology relationship hypertension, focus personalized pharmacological rehabilitation strategies targeting while treating comorbidities.

Hypertension remains a major contributor to cardiovascular disease (CVD), leading cause of global death. One the insults that drive increased blood pressure is inflammation. While it body's defensive response against some homeostatic imbalances, inflammation, when dysregulated, can be very deleterious. In this review, we highlight and discuss causative relationship between inflammation hypertension. We critically how interplay reactive oxygen species evokes endothelial damage dysfunction, ultimately narrowing stiffness vessels. This, along with phenotypic switching vascular smooth muscle cells abnormal increase in extracellular matrix deposition further exacerbates arterial noncompliance. also hyperhomocysteinemia microRNA act as links The premises suggest blue-sky scenarios for targeting underlying mechanisms hypertension necessitate research.
