Abstract Electrochemical aptamer-based (EAB) sensors enable the continuous, real-time monitoring of drugs and biomarkers in situ blood, brain, peripheral tissues live subjects. The concentration information produced by these provides unique opportunities to perform closed-loop, feedback-controlled drug delivery, which plasma a can be held constant or made follow specific, time-varying profile. Motivated observation that site action many is solid not here we experimentally confirm maintaining concentrations also produces interstitial fluid (ISF). Using an intravenous EAB sensor performed feedback control over doxorubicin, anthracycline chemotherapeutic, rats. second placed subcutaneous space, find ISF rapidly (30–60 min) match then accurately (RMS deviation 8–21%) remain at concentration, validating use are action. We expanded pairs ISF, outputs individual track one another with good precision (R2 = 0.95–0.99), confirming performance vivo matches prior, vitro validation studies. These observations suggest could prove powerful new approach high-precision personalization dosing.

Recent advances have greatly improved our understanding of the molecular mechanisms behind atherosclerosis pathogenesis. However, there is still a need to systematize this data from general pathology perspective, particularly with regard atherogenesis patterns in context both canonical and non-classical inflammation types. In review, we analyze various typical phenomena outcomes cellular pro-inflammatory stress atherosclerosis, as well role endothelial dysfunction local systemic manifestations low-grade inflammation. We also present features immune development productive stable unstable plaques, along their similarities differences compared There are numerous factors that act inducers inflammatory process including vascular endothelium aging, metabolic dysfunctions, autoimmune, some cases, infectious damage factors. Life-critical complications such cardiogenic shock severe strokes, associated acute hyperinflammation. Additionally, critical atherosclerotic ischemia lower extremities induces paracoagulation chronic Conversely, sepsis, other conditions, diseases contribute atherogenesis. summary, can be characterized an independent form inflammation, sharing but having fundamental variants (classic vasculitis).

Endothelial dysfunction (ED) is characterized by an imbalance between vasodilatory and vasoconstrictive factors, leading to impaired vascular tone, thrombosis, inflammation. These processes are critical in the development of cardiovascular diseases (CVDs) such as atherosclerosis, hypertension ischemia/reperfusion injury (IRI). Reduced nitric oxide (NO) production increased oxidative stress key contributors ED. Aging further exacerbates ED through mitochondrial oxidative/nitrosative stress, heightening CVD risk. Antioxidant systems like superoxide-dismutase (SOD), glutathione-peroxidase (GPx), thioredoxin/thioredoxin-reductase (Trx/TXNRD) pathways protect against stress. However, their reduced activity promotes ED, vulnerability IRI. Metabolic syndrome, comprising insulin resistance, obesity, hypertension, often accompanied Specifically, hyperglycemia worsens endothelial damage promoting Obesity leads chronic inflammation changes perivascular adipose tissue, while associated with increase The NLRP3 inflammasome plays a significant role being triggered factors reactive oxygen nitrogen species, ischemia, high glucose, which contribute inflammation, injury, exacerbation Treatments, N-acetyl-L-cysteine, SGLT2 or inhibitors, show promise improving function. Yet complexity suggests that multi-targeted therapies addressing metabolic disturbances essential for managing CVDs syndrome.

Chronic Venous Disease (CVD) refers to several pathological and hemodynamic alterations of the veins lower limbs causing a wide range symptoms signs with high prevalence in general population disabling consequences most severe forms. The etiology pathophysiology CVD is complex multifactorial, involving genetic, proteomic, cellular mechanisms that result changes venous structure functions. Expressions genes associated angiogenesis, vascular development, regulation are responsible for susceptibility CVD. Current evidence shows extracellular matrix (ECM) could be identified some cases pharmacologically targeted.

Maintaining tissue perfusion in sepsis depends on vascular integrity provided by the endothelial glycocalyx, critical layer covering luminal surface of blood vessels. The glycocalyx is composed proteoglycans, glycosaminoglycans, and functional plasma proteins that are for antithrombogenicity, regulating tone, controlling permeability, reducing interactions with leukocytes platelets. Degradation substantial due to thromboinflammation, treatments septic shock may exacerbate endotheliopathy via additional injury. As a result, therapeutic strategies aimed at preserving should be considered, including modifications fluid volume resuscitation, minimizing catecholamine use, hyperglycemia, potential use corticosteroids anticoagulants. In this review, we explore treatment aligned recommendations outlined Surviving Sepsis Campaign Guidelines 2021 special emphasis evidence regarding protection.

The endothelial glycocalyx encompasses the entire cell, transducing extracellular signals and regulating vascular permeability barrier functions. apical glycocalyx, which forms lumen of vessel, basal at smooth muscle cell interface, are often investigated separately as they exposed to vastly different stimuli. directly senses fluid shear forces transmitting them intracellularly through connection cytoskeleton cell. has demonstrated sensitivity due blood flow transmitted cytoskeleton, promoting alternate signaling processes. In this review, we discuss current literature on glycocalyx’s response stress in context mechanotransduction remodeling. possible implications degradation pathologies also explored. Finally, review seeks highlight how addressing gaps discussed would improve our wholistic understanding its role maintaining homeostasis.

There is increasing evidence for blood-brain barrier (BBB) alterations in Parkinson's disease (PD), the second most common neurodegenerative disorder with rapidly rising prevalence. Altered tight junction and transporter protein levels, accumulation of α-synuclein increase inflammatory processes lead to extravasation blood molecules vessel degeneration. This could result a self-perpetuating pathophysiology inflammation BBB alteration, which contribute neurodegeneration. Toxin exposure or over-expression animal models has been shown initiate similar pathologies, providing platform study underlying mechanisms therapeutic interventions. Here we provide comprehensive review current knowledge on PD patients how rodent that replicate some these changes can be used mechanisms. Specific challenges assessing healthy controls are discussed. Finally, potential role pathogenesis possible implications therapy explored. The interference novel strategies requires more attention. Brain region-specific also open up opportunities target specifically vulnerable neuronal subpopulations.

The maintenance of the integrity entire endothelium, glycocalyx included, and, therefore, tissue aorta’s homeostasis, depends on expressions several molecular pathways and their interactions, such as syndecan molecules. Alterations in syndecans, i.e., quantitative alterations or linking to shedding, contributes invoking endothelium dysfunction, which causes damage vessel wall due increased production growth-stimulating pro-inflammatory gene products. Inflammatory processes negatively affect endothelial glycocalyx, a dynamic layer luminal portion cells composed proteoglycans, glycoproteins, glycosaminoglycans, syndecans. In turn, structural influence coagulative state, increasing pro-thrombotic processes. family syndecans constitutes major component or, more accurately, source cell surface heparan sulfate. It encompasses four components: syndecan-1, syndecan-2, syndecan-4 (with syndecan-3 only expressed neural tissue), have fundamental role regulating events acute chronic aorta subsequently correlated with formation aneurysms.
