Cystic Fibrosis
Blood Flow and Vascular Function in Cystic Fibrosis
Cystic fibrosis (CF) has many health consequences. A reduction in the ability to perform exercise in patients with CF is related to greater death rates, steeper decline in lung function, and more frequent lung infections.

- Testing
- Sildenafil (Acute-1 hour), Sildenafil (Subchronic-4 weeks)
- Where
- United States
- Volunteers
- 19 people, healthy volunteers welcome

Atherosclerosis
Arterial Function and Atherosclerosis in Essential Thrombocythemia
The aim of the study is to examine (a) whether patients with JAK2 V617F positive ET in comparison to age-and sex-matched, apparently healthy control subjects show more advanced progression of arterial stiffness, pulse-wave…

Efficacy of Polyphenols From Milk and Dark Chocolate
Dark chocolate is one of the richest sources of polyphenols though it has been hypothesised that the bioavailability and therefore probably the bioefficacy of epicatechin from milk chocolate was reduced compared to dark.

- Testing
- Dark Chocolate, Milk Chocolate, Control (polyphenol-free) "Chocolate"
