and B Sperling, merits attention because it describes the novel application of two non-invasive techniques to address the relationship between vessel dilatation and the pain of headache. Ten migraineurs with unilateral headache were subjected to transcranial doppler sonography (to measure blood velocity within the middle cerebral artery) and single photon emission computerized tomography (to me...

Abstract Vascular epiphytes represent almost 10% of all terrestrial plant diversity. Despite the extensive research on functional ecology and challenges epiphytic growth, there is still very little known how exposure to mechanically induced stress affects growth development epiphytes. Therefore, this study investigated effect such mechanical biomass allocation bromeliads. Juvenile plants two sp...

Tissue engineering, using either polymer or biological based scaffolds, represents the newest approach to overcoming limitations of small diameter prosthetic vascular grafts. Their disadvantages include thromboembolism and thrombosis, anticoagulant related haemorrhage, compliance mismatch, neointimal hyperplasia, as well as aneurysm formation. This current review represents an overview about pr...

AIMS Vascular peroxidase 1 (VPO1) is a newly identified haem-containing peroxidase that catalyses the oxidation of a variety of substrates by hydrogen peroxide (H(2)O(2)). Considering the well-defined effects of H(2)O(2) on the vascular remodelling during hypertension, and that VPO1 can utilize H(2)O(2) generated from co-expressed NADPH oxidases to catalyse peroxidative reactions, the aims of t...
