Application of Solid oxide proton-conducting electrolytes for amperometric analysis of hydrogen in H-2+N-2+H2O gas mixtures
(2014)Amperometric hydrogen sensors based on proton-conducting solid electrolytes of La0.95Sr0.05YO3, CaTi0.95Sc0.05O3 and CaZr0.9Sc0.1O3 compositions are prepared and investigated in the present work. The influence of the sensor ... -
Atypical CRM1-dependent nuclear export signal mediates regulation of hypoxia-inducible factor-1 alpha by MAPK
(2008)Hypoxia-inducible factor 1 (HIF-1) is the key transcriptional activator of hypoxia-inducible genes and an important anti-cancer target. Its regulated subunit, HIF-1 alpha, is controlled by oxygen levels and major signaling ... -
Benthic protists and fungi of Mediterranean deep hypsersaline anoxic basin redoxcline sediments
(2014)Some of the most extreme marine habitats known are the Mediterranean deep hypersaline anoxic basins (DHABs; water depth 3500 m). Brines of DHABs are nearly saturated with salt, leading many to suspect they are uninhabitable ... -
CeO2 based materials doped with lanthanides for applications in intermediate temperature electrochemical devices
(2011)The present work aims at the investigation of the influence of different dopants' ionic radius and concentration on the lattice parameters and the density of Ce(1-x)Ln(x)O(2-delta) (x = 0-0.20; Ln = La, Nd, Sm, Eu, Gd, Dy, ... -
Comparative effects of hypoxia on normal and immortalized human diploid fibroblasts
(2006)Hypoxia, a condition of reduced oxygen concentration, is observed in many physiological and pathophysiological states. However, there is rather limited information regarding hypoxic effects in the processes of immortalization ... -
Hydrogen production by ethanol steam reforming over a commercial Pd/-gamma-Al2O3 catalyst
(2004)In the present work the reaction of biomass-derived ethanol steam reforming for hydrogen rich gas streams production, over a commercial alumina supported palladium catalyst was investigated. In particular, the dependence ... -
Hypoxia-inducible factor-1 alpha (HIF-1 alpha) expression in placentae of women with iron deficiency anemia and beta-thalassemia trait
(2015)Objective: To investigate hypoxia-inducible factor-1 alpha (HIF-1 alpha) expression in placentae of women with iron-deficiency anemia and beta-thalassemia trait and to correlate the results with hematological parameters ... -
Increased HIF-1 alpha immunostaining in psoriasis compared to psoriasiform dermatitides
(2009)Background Expression of hypoxia inducible factor 1 (HIF-1) alpha can be linked to inflammation through reciprocal interactions with several cytokines. This finding is in accordance with the previously noted HIF-1 alpha ... -
Low-Frequency Fatigue as an Indicator of Eccentric Exercise-Induced Muscle Injury: The Role of Vitamin E
(2012)This study investigates whether vitamin E can attenuate eccentric exercise-induced soleus muscle injury as indicated by the amelioration of in situ isometric force decline following a low-frequency fatigue protocol ... -
Mussel farming impacts on trophic status and benthic community structure in Maliakos Gulf (Eastern Mediterranean)
(2014)The impact of shellfish farming on the water column nutrient concentration and the benthic community structure was investigated seasonally at a mussel farm (Mytilus galloprovincialis L.) of Maliakos Gulf (Eastern Mediterranean). ... -
Soluble fms-Like Tyrosine Kinase-1 (sFlt-1) and Serum Placental Growth Factor (PlGF) as Biomarkers for Ectopic Pregnancy and Missed Abortion
(2011)Context: Diagnosis of early pregnancy failure is hampered by the lack of reliable serological markers. Objective: We assessed whether a single serum measurement of placental growth factor (PlGF) and the soluble Flt-1 ...
