The demir kapija ophiolite, Macedonia (FYROM): A Snapshot of subduction initiation within a back-arc
2013
The Demir Kapija ophiolitic complex in southern Macedonia–FYROM (Former Yugoslav Republic of Macedonia) represents the southernmost exposure of the Tethyan Eastern Vardar ophiolitic unit in the Eastern Mediterranean. It consists of a mafic volcanic sequence (pillow basalts, sheeted dyke diabases and gabbros) that was subsequently intruded by island arc magmas with and without adakitic affinity. The mafic volcanic sequence is characterized by slightly increased ratios of large ion lithophile elements to high field strength elements (LILE/HFSE), flat rare earth element (REE) patterns, radiogenic 143Nd/144Nd (up to 0·51272) and high TiO2 contents (which reflect Pl + Ol + Cpx fractionation). Th…

Immunological insights into the pathogenesis of active CMV infection in non-immunosuppressed critically ill patients.
2011
Dissociation of cytomegalovirus (CMV) DNA loads between the lower respiratory tract and blood, with high levels in the former compartment and low or undetectable levels in the latter, commonly occurs during active CMV infection in critically ill patients despite the presence of high frequencies of CMV-specific IFN-γ-producing CD8+ and CD4+ T cells in blood. Data presented in this case report suggest that inter-compartmental differences in interleukin-10 (IL-10) levels may, in part, explain the pathobiology of this phenomenon. In the absence of ganciclovir treatment, a significant correlation was observed between IL-10 levels and CMV DNA loads in lower respiratory tract specimens (P = 0.016)…
LATE-BREAKING ABSTRACT: MUC1 downregulation induces corticosteroid resistance in asthma'sin vitroandin vivomodels
2016
Background: Corticosteroids are in the first-line of Asthma treatment. However a subset of asthmatic patients is insensitive to anti-inflammatory effects of corticosteroids. Our previous data demonstrated that MUC1 downregulation correlates corticosteroid resistance in Nasal Polyposis and COPD. We hypothesized that MUC1 is also involved in corticosteroid resistance in Asthma. Objective: To analyze the role of MUC1 in the corticosteroid effectiveness in Asthma9s in vitro and in vivo models. Methods: 20 patients with steroid resistant Asthma were recruited. The expression of MUC1 was determined by real-time PCR in inflammatory cells from peripheral blood. HMVEC-L and U937 cells knockdown with…
Effects of waterborne iron overload and simulated winter conditions on acute physiological stress response of whitefish, Coregonus lavaretus
2003
Two-year-old whitefish (Coregonus lavaretus) were exposed for 30 days to episodic iron overload in iron-rich humic water (5%) supplemented with inorganic iron (5 mg FeL(-1)). Two parallel laboratory exposures were performed, one under conditions simulating winter and the other under conditions simulating spring. After exposure, some of the fish were subjected to acute handling stress in the form of a short air challenge to reveal possible modification of the primary and secondary stress responses. In whitefish sampled without additional handling, iron accumulated in the liver (under spring conditions) and gills (under winter and spring conditions); plasma catecholamine and beta-estradiol (b…
Oxycarenus lavaterae (FABRICIUS, 1787) (Hemiptera: Heteroptera: Oxycarenidae) – gatunek nowy dla fauny Polski
2016
Oxycarenus lavaterae (Hemiptera: Heteroptera: Oxycarenidae) has been collected from a Platanus acerifolia in Rzeszów-Słocina, Southeastern Poland. This is the first record of this species from Poland.
Dane na temat rozprzestrzeniania się inwazyjnego gatunku Oxycarenus lavaterae (Fabricius, 1787) (Heteroptera: Lygaeoidea: Oxycarenidae) w południowo-…
2019
Oxycarenus lavaterae (Fabricius, 1787), the invasive true bug species, were recorded from Poland for the first time in 2014 (SE Poland, Rzeszów; Hebda & Olbrycht, 2016). Since that time it was recorded also in Cieszyn (Western Beskid Mts) and Brzeg (Lower Silesia) in August 2018 (Gierlasiński et al., 2018). In October, November and December 2018 and January 2019, many new populations of this species were reported in south-west regions of Poland (Lower Silesia: Jawor, Legnica, Nysa, Opole, Oława, Racibórz, Świdnica, Wrocław; Upper Silesia: Zdzieszowice) what confirms the species expansion to the north of Poland.
From the bulla of Julius II (1504) to the conclusions of Fray Pedro de Álava (1594) : the long process of validating the second marriage of Rodrigo d…
2021
Tratamos en este trabajo sobre los matrimonios de Rodrigo de Mendoza, primer marqués del Cenete, sus azarosas circunstancias y sus consecuencias a través de un largo proceso que se inició en 1492, mediante las capitulaciones matrimoniales por su boda con Leonor de la Cerda, y finalizó en 1594, tras las conclusiones de fray Pedro de Álava con respecto a la legitimación de su segunda unión con María de Fonseca, casi un siglo después de esta. Acontecimientos que nos sirven para ir reconstruyendo el perfil biográfico de uno de los nobles más peculiares y controvertidos de su tiempo a caballo entre el Medioevo y el Renacimiento, hijo primogénito a su vez del Gran Cardenal de España, Pedro Gonzál…
The control of lava flow during the 1991–1992 eruption of Mt. Etna
1993
Abstract All the actions carried out in 1992 to protect the village of Zafferana Etnea from being invaded by lava are described. An earthen barrier 234 m long and 21 m high was firstly built in January 1992 by accumulating with mechanical escavators 370,000 m 3 of earth, scoriae and stones. This embankment contained the lava for about one month and was overflowed by April 9, 1992. Three additional smaller earthen barriers (lenght: 90–160 m; height: 6–12 m) were built in April to gain time while the lava front was descending towards Zafferana from the overflowed first embankment. The major effort of the 1992 operation consisted of several attempts at stopping the lava front advance by divert…
Protection by beverages, fruits, vegetables, herbs, and flavonoids against genotoxicity of 2-acetylaminofluorene and 2-amino-1-methyl-6-phenylimidazo…
2002
Abstract Chinese hamster lung fibroblasts, genetically engineered for the expression of rat cytochrome P450 dependent monooxygenase 1A2 and rat sulfotransferase 1C1 (V79-rCYP1A2-rSULT1C1 cells), were utilized to check for possible protective effects of beverages of plant origin, fruits, vegetables, and spices against genotoxicity induced by 2-acetylaminofluorene (AAF) or 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP). Antigenotoxic activities of juices from spinach and red beets against AAF could be monitored with similar effectivity by the HPRT-mutagenicity test (IC50=0.64%; 2.57%) and alkaline single cell gel electrophoresis (comet assay; IC50=0.12%; 0.89%) which detects DNA stran…
