Mythes, symboles, rituels. Le pouvoir historique des « signes » en Europe du Sud-Est aux XIX et XXe siècles, colloque, Bonn, 15-17 septembre 1997

L’Europe du sud-est jouit depuis plusieurs années de l’attention toute particulière des sciences sociales. Hélas, cet intérêt est également provoqué par les événements qui se sont déroulés ces dernières années dans l’ancienne Yougoslavie. Une partie des recherches sur l’Europe du sud-est concerne les débats et les effets des mythes parmi les nations de cette partie de l’Europe. Le colloque de Bonn devait précisément contribuer à la recherche sur les courants sociaux en Europe du sud-est. Orga..

Interplay between Comprehensive Inflammation Indices and Redox Biomarkers in Testicular Germ-Cell Tumors

Sustained and dysregulated inflammation, concurrent tumor-induced immune suppression, and oxidative stress are profoundly involved in cancer initiation, presentation, and perpetuation. Within this prospective study, we simultaneously analyzed the preoperative indices of systemic inflammatory response and the representative byproducts of oxidative DNA, protein, and lipid damage with the aim of evaluating their clinical relevance among patients diagnosed with testicular germ-cell tumors (GCT). In the analytical cohort (n = 88, median age 34 years), neutrophil-to-lymphocyte ratio (NLR), derived neutrophil-to-lymphocyte ratio (dNLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), systemic immune-inflammation index (SII), systemic inflammation response index (SIRI), and C-reactive protein (CRP) were significantly altered in patients with a higher tumor stage (p < 0.05). Highly suggestive correlations were found between NLR, dNLR, and SII and modified nucleoside 8-OHdG. CRP and albumin-to-globulin ratio (AGR) significantly correlated with thiols group level and maximal tumor dimension (p < 0.05). Based on receiver operating characteristic (ROC) curve analyses, all the evaluated pre-orchiectomy inflammation markers demonstrated strong performance in predicting metastatic disease; optimal cut-off points were determined for each indicator. Although further large-scale studies are warranted, inflammatory and redox indices may both complement the established tumor markers and standard clinicopathological prognostic variables and contribute to enhanced personalized risk-assessment among testicular GCT patients

Mechanochemical synthesis Ba0.8Sr0.2TiO3

Ba0.8Sr0.2TiO3 was prepared from the starting materials BaCO3, SrCO3 and TiO2 through solid state reaction. Mixture of these oxides was mechanically activated using a high-energy ball mill at different time intervals from 0 to 120 minutes. The crystal structure was determined by X-ray diffraction to obtain information about the composition of phase variation. It was observed that after 40 minutes occurred early synthesis Ba0.8Sr0.2TiO3. Particle size distribution along with scanning electron microscopy gave very useful information about powder morphology
