BACKGROUND: Dipyridamole is used for stress (82)rubidium chloride ((82)RbCl) PET because of its long hyperemic duration. Regadenoson has advantages of a fixed dose and favorable symptom profile, but its mean maximal hyperemia is only 2.3 minutes. To determine its suitability for (82)RbCl PET, we imaged subjects using a regadenoson protocol based ...

Neurofibromatosis type 2 (NF2) is an autosomal-dominant disorder affecting about 1:33 000 newborns, mainly characterized by the development of tumors of the nervous system and ocular abnormalities. Around 85% of germline NF2 mutations are point mutations. Among them, ∼25% affect splicing and are associated with a variable disease severity. In the ...

At the beginning of the last century obesity and type 2 diabetes were treated quite successfully using low-carbohydrate diets. Following the discovery of insulin, the carbohydrate content of the diabetic diet became more liberal, as glycaemia and glycosuria could be controlled, more or less well, with hypoglycaemic medication and insulin ...

Phenoxy radical coupling reactions are involved in the biosynthesis of lignans in planta. Interestingly, the reaction can be guided by dirigent proteins, which mediate the stereoselective formation of either (+) or (-)-pinoresinol from coniferyl alcohol. So far, the mechanism is poorly understood, and for detailed mechanistic studies, a heterologous expression ...

BACKGROUND: The hormone and neuropeptide arginine-vasopressin is designated to the maintenance of osmotic homoeostasis and blood pressure regulation. While experimental data show vasopressin V(1A) receptors to regulate aquaporin (AQP)4 water channel dependent brain water movement, the specific role in vasogenic and cytotoxic edema formation remains unclear. The present study was ...

Habitat fragmentation has been shown to disrupt ecosystem processes such as plant-pollinator mutualisms. Consequently, mating patterns in remnant tree populations are expected to shift towards increased inbreeding and reduced pollen diversity, with fitness consequences for future generations. However, mating patterns and phenotypic assessments of open-pollinated progeny have rarely been combined ...
