The possible involvement of dopaminergic neurons in dementia of Alzheimer type (AD/SDAT) was studied in autopsied brains from 20 patients with AD/SDAT. Dopamine (DA) concentrations were decreased significantly in the temporal cortex, hippocampal cortex and hippocampus in AD/SDAT patients. Levels of homovanillic acid (HVA) were not altered compared to(More)
To investigate changes in the somatostatinergic neurons of patients with Alzheimer's disease (AD), we determined the somatostatin-like immunoreactivity (SLI) in post-mortem brain tissue of histopathologically confirmed AD patients and in CSF of probable AD patients (according to DSM III). The CSF values were then correlated with psychological test scores.(More)
A retrospective analysis of 321 gastric cancer patients was made to assess the prognostic value of TNM classification, tumour differentiation, Laurén classification, proliferative rate, inflammatory reaction and tumour invasion in vascular or neural structures of the gastric wall. The TNM classification showed the strongest correlation with survival in(More)
The short arm of the chromosome 11, known to harbour a number of putative and established tumour-suppressor genes, is frequently hypermethylated in various human neoplasms. We subjected the promoter regions of two genes residing at 11p, namely the tumour-suppressor gene WT1 (Wilms' tumour gene) (11p13) and the calcitonin gene (11p15.5), to methylation(More)
The loss of transcription factor AP-2alpha expression has been shown to associate with tumourigenicity of melanoma cell lines and poor prognosis in primary cutaneous melanoma. Altogether these findings suggest that the gene encoding AP-2alpha (TFAP2A) acts as a tumour suppressor in melanoma. To learn more of AP-2alpha's down-regulation mechanisms, we(More)
Clinical data from 369 patients with clinical stage I cutaneous malignant melanoma treated in Kuopio University Hospital district between 1974 and 1989 with a mean follow-up of 6.4 years were analysed. Clinical parameters, histology, DNA index, S-phase fraction (SPF) and mitotic indices [mitotic activity index (MAI) and volume-corrected mitotic index (M/V(More)

Environmental releases of insoluble nuclear fuel compounds may occur at nuclear power plants during normal operation, after nuclear power plant accidents, and as a consequence of nuclear weapons testing. For example, the Chernobyl fallout contained extensive amounts of pulverized nuclear fuel composed of uranium and its nonvolatile fission products. The(More)
