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)
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 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)
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)
Angiogenesis is essential for tumor growth beyond a few millimeters in diameter, and the intratumoral microvessel count that represents a measure of angiogenesis has been correlated with tumor behavior in a variety of different tumor types. To date no systematic study has assessed pituitary tumors of different secretory types, correlating vascular count(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)
Intracellular beta-galactosidase from Penicillium chrysogenum NCAIM 00237 was purified by procedures including precipitation with ammonium sulfate, ion-exchange chromatography on DEAE-Sephadex, affinity chromatography, and chromatofocusing. These steps resulted a purification of 66-fold, a yield of about 8%, and a specific activity of 5.84 U mg(-1) protein.(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)
