2-Oxoglutarate-dependent oxygenases control hepcidin gene expression
(2008)Background/Aims: Hepcidin is a liver-produced hormone that regulates systemic iron homeostasis. Hepcidin expression is stimulated upon iron overload or inflammation while iron deficiency, anemia and tissue hypoxia are ... -
Assessment of trace element pollution in northern and western Iranian agricultural soils: a review
(2021)The pollution of Iranian agricultural soils with trace elements (Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and Zn) was assessed and compared with other agricultural soils around the world. Experimental data on trace element content ... -
Cobalt induces hypoxia-inducible factor-1 alpha (HIF-1 alpha) in HeLa cells by an iron-independent, but ROS-, PI-3K- and MAPK-dependent mechanism
(2006)The iron-chelator desferrioxamine (DFO) and the transition metal cobalt induce hypoxia-inducible factor-1 alpha (HIF-1 alpha) in normoxia. DFO stabilizes HIF-1 alpha from proteolysis by inhibiting the activity of iron-dependent ... -
Endograft Specific Haemodynamics After Endovascular Aneurysm Repair: Flow Characteristics of Four Stent Graft Systems
(2019)Objectives: The implication of haemodynamics in the occurrence of complications after endovascular aneurysm repair (EVAR) has been raised in the literature. Different aortic stent graft configurations may lead to different ... -
Enhanced oxygen reduction and methanol oxidation reaction over self-assembled Pt-M (M = Co, Ni) nanoflowers
(2022)Herein, we introduce a facile approach to synthesize a unique class of Pt-M (M = Ni, Co) catalysts with a nanoflower structure for boosting both oxygen reduction reaction (ORR) and methanol oxidation reaction (MOR). By ... -
Exposure of differentiated airway smooth muscle cells to serum stimulates both induction of hypoxia-inducible factor-1 alpha and airway responsiveness to ACh
(2007)Airway smooth muscle (ASM) cells are characterized by phenotypic plasticity and can switch between differentiated and proliferative phenotypes. In rabbit tracheal ASM cells that had been differentiated in vitro by serum ... -
Monitoring potentially toxic element pollution in three wheat-grown areas with a long history of industrial activity and assessment of their effect on human health in central Greece
(2021)Agricultural lands, especially those where wheat is cultivated, in the vicinity of intense anthropogenic activities may be laden with potentially toxic elements (PTEs), resulting in increased risk for human health. In this ... -
Pollution assessment of potentially toxic elements in soils of different taxonomy orders in central Greece
(2019)Four hundred fifty soil samples of the orders of Alfisols, Inceptisols, Endisols, and Vertisols from Karditsa, Trikala, and Larissa (Central Greece) were collected over a three-year period. In these samples we analyzed ... -
Release of toxic elements in fishpond sediments under dynamic redox conditions: Assessing the potential environmental risk for a safe management of fisheries systems and degraded waterlogged sediments
(2020)Waterlogged soils and sediments contaminated with potentially toxic elements (PTEs) constitute a complicated case of degraded areas; their management requires understanding of the dynamic redox-driven PTE mobilization. ... -
Soil and maize contamination by trace elements and associated health risk assessment in the industrial area of Volos, Greece
(2019)Agricultural lands adjacent to industrial activities are vulnerable due to the risk of trace elements (TEs) being accumulated into crops and subsequently humans. One such case concerns the industrial area of Volos, Greece, ... -
Soil contamination by potentially toxic elements and the associated human health risk in geo- and anthropogenic contaminated soils: A case study from the temperate region (Germany) and the arid region (Egypt)
(2020)Soil contamination was very high in the studied soils (pollution load index ranged from 1.1 to 5.2), especially in the German and Egyptian Fluvisols; health risk for children was higher than for adults, and As, Al, Cr, Cu, ...
