Reductions in regional cerebral perfusion, particularly in the posterior temporo-parietal lobes, are well recognized in Alzheimer's disease. We set out to correlate perfusion changes, using (99m)Tc-HMPAO single photon emission tomography (SPET), with the pathological stage of Alzheimer's disease. The 'Braak stage' of the distribution of neurofibrillary(More)
The effect of the apolipoprotein E genotype on the development of late onset Alzheimer's disease is still debated. Neuropathological studies of Alzheimer's disease have found a great extent of amyloid deposition in cortex and blood vessel walls in association with the apolipoprotein E epsilon 4 genotype [Rebeck G. W. et al. (1993) Neuron 11, 575-580;(More)
Peroxisome proliferator-activated receptor γ (PPARγ) is a lipid-activated transcription factor regulating lipid metabolism and inflammatory response in macrophages and dendritic cells (DCs). These immune cells exposed to distinct inflammatory milieu show cell type specification as a result of altered gene expression. We demonstrate here a mechanism how(More)
OBJECTIVE Survival analysis of a series of 366 consecutive patients with systemic sclerosis (SSc). METHODS Clinical and laboratory data were evaluated from 1983 until 2005 using a standard protocol. The female/male ratio was 315/51. The mean (SD) age of the patients was 56.8 (12.2) years. The duration of disease was 12 (5-19) years with a median follow-up(More)
The presence of megacapillaries and a decreased capillary density are the hallmarks of the scleroderma capillary pattern, which can be detected by nailfold capillarmicroscopy. One hundred and eighty-six patients with Raynaud's phenomenon, 65 cases with undifferentiated connective tissue disease (UCTD), 47 patients with systemic lupus erythematosus (SLE), 26(More)
We have performed a quantitative analysis of the amyloid load (plaques), neuritic plaques and neurofibrillary tangles (NFT) in the frontal, temporal and parietal association cortices of autopsied brains from 49 prospectively evaluated patients with Alzheimer's disease (AD) diagnosed according to three sets of published pathological criteria. These patients(More)
The diagnosis of Alzheimer disease (AD) according to current criteria is a combined clinical and pathological exercise. The clinical discrimination of AD from other types of dementia may be complicated when the patient suffers from more than one disease. In particular the concomitant presence of other neurological conditions may significantly influence the(More)
Angiogenesis has been shown to be related to tumour behaviour, prognosis and response to treatment in many different tumour types. The aim of this study was to examine the relationship between angiogenesis and tumour behaviour and response to treatment in pituitary adenomas. The microvessel density (MVD) of pituitary tumours was assessed by counting blood(More)
Tumor endothelial markers (TEMs) that are highly expressed in human tumor vasculature compared with vasculature in normal tissue hold clear therapeutic potential. We report that the C-type lectin CLEC14A is a novel TEM. Immunohistochemical and immunofluorescence staining of tissue arrays has shown that CLEC14A is strongly expressed in tumor vasculature when(More)
