Expression and prognostic value of the CD44 splicing variants v5 and v6 in gastric cancer
1997
In the present study, the expression and prognostic role of the CD44 splicing variants v5 and v6 were immunohistochemically investigated in 418 curatively resected gastric carcinomas. CD44v5 was expressed in 65·3 per cent (n=273) and CD44v6 in 77·0 per cent (n=322) of the tumours. Whereas the expression of CD44v5 was correlated with advanced pT categories, with lymph node involvement, and with the presence of blood and lymphatic vessel invasion, such a correlation could not be found for the variant v6. As shown by univariate analysis, patients with CD44v5-positive tumours had a significantly shorter overall survival than patients with CD44v5-negative tumours (P=0·049). In contrast, expressi…

Assessment of sleep disturbance in oral lichen planus and validation of PSQI: A case-control multicenter study from the SIPMO (Italian Society of Ora…
2021
Background: The wellbeing of oral lichen planus patients (OLPs) may be strongly influenced by a poor quality of sleep (QoS) and psychological impairment. The aims were to analyze the prevalence of sleep disturbance, anxiety, and depression in OLPs and to validate the Pittsburgh Sleep Quality Index (PSQI) in OLPs. Methods: Three hundred keratotic OLPs (K-OLPs), 300 with predominant non-keratotic OLP (nK-OLPs), and 300 controls were recruited in 15 Italian universities. The PSQI, Epworth Sleepiness Scale (ESS), Hamilton Rating Scales for Depression and Anxiety (HAM-D and HAM-A), Numeric Rating Scale (NRS), and Total Pain Rating Index (T-PRI) were administered. Results: Oral lichen planus pati…

The masticatory system has often proved very useful for the identification of unkown bodies. The technique of excising the mandible and the maxilla is explained. The evaluation and the preparation of models are described. For registration of the findings a new form has been developed. It is based on the old form "KP 16" as well as on the PA status.

Significance of Various Enzymes in the Control of Mutagenic and Carcinogenic Metabolites Derived from Aromatic Structures
1984
One important early contribution to the control of chemical carcinogenesis is provided by the enzyme pattern responsible for the generation and disposition of reactive metabolites. Especially well studied is the important group of enzymes responsible for the control of reactive epoxides. Many natural as well as man-made foreign compounds, including Pharmaceuticals, possess olefinic or aromatic double bonds. Such compounds can be transformed to epoxides by microsomal monooxygenases present in very many mammalian organs. By virtue of their electrophilic reactivity such epoxides may spontaneously react with nucleophilic centers in the cell and thus covalently bind to DNA, RNA, and protein. Su…
Variations of components of the plasminogen activation system with the cell cycle in benign prostate tissue and prostate cancer
2001
Background: Components of the fibrinolytic system are involved in tumor cell invasion and metastasis. Previous investigations suggested a cell cycle-dependent expression of urokinase-type plasminogen activator (u-PA) in epithelial cells. In order to determine a correlation of cell cycle phases with the fibrinolytic system, we investigated the expression of u-PA, tissue-type plasminogen activator (t-PA), and plasminogen activator inhibitor type 1 (PAI-1) in normal and tumor-containing prostate extracts and analyzed a possible relationship with flow cytometry-determined proliferative activity of the samples. Cell cycle phases were correlated with fibrinolytic parameters in prostate tissue. Me…

Persistent lipsticks and their lip prints: new hidden evidence at the crime scene
2000
Latent lip print test results produced by permanent lipsticks are presented in this work. This cosmetic product, contrary to conventional lipsticks, does not leave visible prints and can thus be overlooked at the crime scene. As print vehicles the study used ceramics, glass, cotton fabric and paper. Lip prints were left to dwell for different periods and were later developed using aluminum powder, cobalt oxide powder and magnetic powder. The results show that identifiable lip prints can be obtained up to 30 days after being produced.
