Endothelium-derived extracellular particles (CD146) were increased in stable relapsing-remitting multiple sclerosis patients (n = 17) compared to healthy controls (p < 0.05). Extracellular particles from several different cells of origin correlated with each other and clinical parameters (e.g. disease duration, number of relapses, EDSS), though clinical correlations did not withstand corrections for multiple comparisons. Conclusions: Concentrations of erythrocyte-, leukocyte-, and platelet-derived extracellular particles were altered in relapsing multiple sclerosis patients and endothelium-derived extracellular particles were increased in stable relapsing-remitting patients compared to healthy controls. Extracellular particles may provide insights into altered the crosstalk between peripheral blood cells in multiple sclerosis, which may lead to the discovery of novel therapeutic targets.]]> Wed 23 Feb 2022 11:05:08 AEDT ]]> “LONG COVID”—A hypothesis for understanding the biological basis and pharmacological treatment strategy https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47033 Thu 30 Mar 2023 19:16:20 AEDT ]]> Asymmetric dimethylarginine: a possible link between vascular disease and dementia https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:23647 Thu 13 Oct 2016 11:33:45 AEDT ]]> Recombinant perlecan domain V covalently immobilized on silk biomaterials via plasma immersion ion implantation supports the formation of functional endothelium https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50893 Thu 10 Aug 2023 17:07:23 AEST ]]> Anthocyanins attenuate vascular and inflammatory responses to a high fat high energy meal challenge in overweight older adults: A cross-over, randomized, double-blind clinical trial https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:42832 2 SD 3.9) participated in a crossover, randomized, controlled, double-blind clinical trial (registered under Australian New Zealand Clinical Trials Registry, identifier no. ACTRN12620000437965). Participants consumed a HFHE meal with a 250 mL dose of either intervention (anthocyanins-rich Queen Garnet Plum) or control (apricot) juice. Blood samples and blood pressure measures were collected at baseline, 2 h and 4 h following the HFHE meal. Vascular and microvascular function were evaluated at baseline and 2 h after the HFHE meal. Results: Participants had a higher 2 h postprandial flow-mediated dilatation (+1.14%) and a higher microvascular post-occlusive reactive hyperaemia (+0.10 perfusion units per mmHg) when allocated to the anthocyanin compared to the control arm (P = 0.019 and P = 0.049, respectively). C-reactive protein was lower 4 h postprandially in the anthocyanins (1.80 mg/L, IQR 0.90) vs control arm (2.30 mg/L, IQR 1.95) (P = 0.026), accompanied by a trend for lower concentrations of interleukin-6 (P = 0.075). No significant postprandial differences were observed between treatments for blood pressure, triacylglycerol, total cholesterol, serum derivatives of reactive oxidative metabolites, tumor necrosis factor alpha, interleukin-1 beta, or maximum microvascular perfusion following iontophoresis of acetylcholine. Conclusion: Fruit-based anthocyanins attenuated the potential postprandial detrimental effects of a HFHE challenge on parameters of vascular and microvascular function, and inflammatory biomarkers in overweight older adults. Anthocyanins may reduce cardiovascular risk associated with endothelial dysfunction and inflammatory responses to a typical high fat 'Western' meal. Further studies are required to better elucidate the clinical implications of postprandial biomarkers of CVD.]]> Mon 05 Sep 2022 12:31:21 AEST ]]>
