Vitamin c to Improve Tissue healing by Administration of Multiple INtravenous dosages

PrimaryImproved woundhealing in 30 days in patients with an open revascularisation of the lower extremities after treatment with 4 dosages of 2 grams ascorbic acid on 4 consecutive days. (First dosage 1 hour preoperative)SecondaryWith preoperative…

Prevent CardioKids

The aim of Prevent CardioKids is to evaluate to what extend disturbed vascular function markers are present in children of different weight categories and whether these are age dependent. Also differences * and relationships between * vascular…

Cardiovascular Riskprofile in Women: Microvascular Status

To gain further insight into the interaction and possibly shared pathophysiological mechanisms of female-specific cardiovascular risk factors and events we will quantify white matter hyperintensities on brain MRI and assess endothelial function in…

Prevention of skeletal muscle and myocardial free-fatty acid induced microvascular dysfunction in skeletal muscle and myocardium by exercise

We hypothesize that the amount of physical activity correlates with insulin-induced microvascular recruitment during free-fatty acid infusion in skeletal muscle as well as in the heart. In this study we aim to test this hypothesis.

Human intestinal ischemia and reperfusion

This study aims at (further) revealing the pathophysiology of intestinal IR in man, with a specific interest for the role of proteases and protease-activated receptor-2 (PAR-2), cellular and inflammatory changes, barrier function and intestinal…

Double-blinded, randomised, placebo-controlled, multicentre , Phase IIa study to investigate the effect, safety and tolerability of phosphorylcholine human monoclonal antibody (PC-mAb) 3G10 on arterial inflammation, together with safety and tolerability, in subjects with elevated lipoprotein a (Lp[a ])

1. The primary objective is to assess the effects of four 250 mg PC-mAB (also referred to as "3G10") once monthly intravenous injections on monocyte function ex vivo. The secondary objectives are to:1. assess the functional effects of 3G10…

Concomitant presence of celiac disease in patients with type 1 diabetes mellitus; investigation of the microvascular function

Aim of the study is to determine the microvascular function in type 1 diabetes patients with concomitant celiac disease

The RVCL-ID study - Identifying biomarkers and disease stages of Retinal Vasculopathy with Cerebral Leukodystrophy (RVCL), a monogenic vascular migraine model

1. To identify presymptomatic and symptomatic profiles including (early) disease stages and early biomarkers of disease progression and to elucidate pathophysiological mechanisms, we will investigate RVCL patients at different ages (both symptomatic…

Glycocalyx in cerebral small vessel disease

Measuring the thickness of the microvascular glycocalyx, and make a comparement between lacunar stroke patients and healthy controls.We also compare glycocalyx between patients with and without concomitant silent signs of cSVD on brain MRI.

Pulse Transit Time in patients with Complex Regional Pain Syndrome

To develop pulse transit time into a diagnostic device which can be used to assess an altered cold/heat mediated vasomotor response (CHMV) (central component) and the flow-mediated dilatation (FMD) (peripheral component) in CRPS patients.

New Hoorn Study:
*Cause and consequences of disturbed microcirculation: effects of glucose tolerance status*

1. Do body fatness and/or body fat distribution show a linear association withmicrovascular function in normal as well as IGT subjects?2. Is the effect of body composition on the microvasculature mediated by alteredadipokine profile, low-grade…

Macrophage infiltration and adipocytokine expression in subcutaneous and visceral fat tissue in patients with Cushing's syndrome.

To describe the differences in macrophage infiltration and mRNA expression of adipocytokines in subcutaneous, omental and perirenal fat tissue in Cushing's syndrome compared to healthy controls.

Residual effects of Cushing*s syndrome after long term remission: Impact on adipose tissue, insulin resistance, exercise intolerance and increased risk of cardiovascular disease.

To identify some of the mechanisms in patients in remission of Cushing*s syndrome that contribute to the persistence of visceral obesity, systemic inflammation, insulin resistance, sarcopenia, a low muscle oxidative capacity and increased risk of…

Are AGEs, as a predictor of increased risk for cardiometabolic syndrome, increased in shift workers?

The aim of this study is to investigate skin AGEs, as a predictor of increased risk for cardiometabolic syndrome, in a shift work population as compared to non-shift workers to assess its potential as an early assessment of the actual risk for…

The effect of cervical spinal cord stimulation on the cerebral blood flow

Effect of SCS on CBF

The effect of hesperidin administration on endothelial function and gut barrier function

To determine the chronic and acute effects of daily administration of hesperidin on cardiovascular and intestinal health as assessed by investigation of endothelial function, blood pressure, heart rate, glucose/insulin metabolism, lipid metabolism…

ANCA associated vasculitis is a relapsing disease; the role of regulatory B cells

Our overall objective is to better understand the role of regulatory B cells in disease pathogenesis and to better predict disease flares in order to individualize treatment.

The RVCL-MRI study: neuroimaging findings and cerebrovascular reactivity in preclinical and clinical disease stages of Retinal Vasculopathy with Cerebral Leukodystrophy (RVCL), in migraine patients and healthy controls.

1. To assess neuroimaging hallmarks of RVCL disease stages;2. To evaluate cerebrovascular reactivity as a biomarker of endothelial (dys)function in RVCL patients, in migraine patients and healthy controls;3. To identify shared pathophysiological…

Postprandial insulin release and the impact on muscle perfusion

We hypothesize, that during an oral glucose tolerance test, the OPS arterial flow measured sublingual will be comparable within the same subject, but different between young, elderly and type 2 diabetic patients. Objective is to quantify differences…
