Alzheimer's disease (AD) is characterized by progressive neurodegeneration leading to loss of cognitive abilities and ultimately to death. Postmortem investigations revealed decreased expression of cerebral insulin-like growth factor (IGF)-1 receptor (IGF-1R) and insulin receptor substrate (IRS) proteins in patients with AD. To elucidate the role of(More)
The expression of adrenomedullin (AM) and atrial natriuretic factor (ANF) were investigated in the myocardium of a rat model of chronic ischemic heart failure (CHF) compared with sham-operated controls. In addition, human myocardium of patients with end-stage heart failure due to idiopathic dilated cardiomyopathy compared with myocardium of normal subjects(More)
Fruit allergy is frequently associated with birch pollinosis. The aim of this study was to investigate which kiwi allergens were involved in subjects allergic to fruit alone and in patients allergic to both fruit and birch pollen. Sera of nine patients (five with both kiwi and birch pollen allergy and four with isolated kiwi allergy) were studied by(More)

Video games have challenged this concept, as the distance between game players and characters is greatly reduced, if not completely removed, in virtual environments. Games encourage the internalization and psychological merging of(More)
The internalization of near-infrared fluorescently labeled cargos into living cells and tissues allows a highly sensitive detection without interference from skin, porphins or other fluorescent cell and tissue compounds. In this study, the uptake of labeled bovine serum albumin and an antibody, into fibrosarcoma (HT-1080) cells was triggered by the(More)
