The Light Cycler technique combines rapid in vitro amplification of DNA in glass capillaries with real-time species determination and quantification of DNA load. We have established a quantitative PCR protocol for two clinically important pathogens, Candida albicans and Aspergillus fumigatus. The sensitivity of the assay was comparable to those of(More)
In 1988 and 1989, thousands of harbor seals (Phoca vitulina) died in the North Sea from phocine distemper infection. The morphology of thyroid glands from 40 harbor seals found dead on the North Sea coastlines of Schleswig-Holstein, Federal Republic of Germany, during an epizootic of phocine distemper, was compared with the morphology of thyroid glands from(More)
The phenotypical characteristics of human epithelial and lymphoid cells have been studied with immunohistochemical methods on frozen sections of 12 thymomas. On the basis of the cytohistological characteristics of thymoma epithelial cells (EC) the thymomas were divided in cortical, medullary and mixed types, according to recently developed light(More)
Quantification and normalization of RT-qPCR data critically depends on the expression of so called reference genes. Our goal was to develop a strategy for the selection of reference genes that utilizes microarray data analysis and combines known approaches for gene stability evaluation and to select a set of appropriate reference genes for research and(More)
PURPOSE The cell adhesion molecule CEACAM1 is involved in intercellular adhesion and subsequent signal transduction events in a number of epithelia. CEACAM1 downregulation has been demonstrated in colorectal and prostate carcinomas. This study sought to analyze whether its expression in malignant melanoma is associated with metastasis. PATIENTS AND(More)
PURPOSE About 50% of prostate cancers have TMPRSS2-ERG fusions with concurrent ERG overexpression. The aim of this study was to determine whether clinical differences exist between ERG-positive and ERG-negative cancers in surgically treated patients not exposed to antihormonal therapy. A secondary aim was to search for differences between these tumor(More)
Modulation of cell adhesion molecule expression plays a key role in melanoma metastasis. In particular, the expression of the cell adhesion molecule L1 has been associated with the metastatic phenotype in a murine model of malignant melanoma. However, no such association between L1 expression and metastasis has been investigated in a clinical study.(More)
Aiming at more precise detection of melanoma cells in sentinel lymph nodes and better understanding of the mechanisms underlying metastatic spread, expression of L1, CEACAM1, and binding of the lectins HPA, ML-I and PNA, was assessed in benign nevi (n=12), primary melanomas (PTs: n=67), their corresponding sentinel lymph nodes (SLNs: n=40), and distant(More)
Resection specimens from 145 patients with primary B-cell gastric lymphoma at stage IE (n = 88) and at stage IIE (n = 57) were investigated. Histologically, low-grade malignant B-cell lymphomas arising from the mucosa-associated lymphoid tissue, including immunocytoma (n = 71), could be distinguished from high-grade malignant B-cell lymphomas with (n = 25)(More)
