Accumulation of lead (Pb) in brown trout (Salmo trutta) from a lake downstream a former shooting range
Mariussen, Espen; Heier, Lene Sørlie; Teien, Hans-Christian; Pettersen, Marit Nandrup; Holth, Tor Fredrik; Salbu, Brit; Rosseland, Bjørn Olav (2017)An environmental survey was performed in Lake Kyrtjønn, a small lake within an abandoned shooting range in the south of Norway. In Lake Kyrtjønn the total water concentrations of Pb (14 µg/L), Cu (6.1 µg/L) and Sb (1.3 ... -
Assessment of intake of copper and lead by sheep grazing on a shooting range for small arms: a case study.
Johnsen, Ida Vaa; Mariussen, Espen; Voie, Øyvind Albert (2018-04-11)The Norwegian Armed Forces’ shooting ranges contain contamination by metals such as lead (Pb) and copper (Cu) and are often used as grazing pastures for livestock. To determine whether the sheep were at risk from grazing ... -
Brain infection with Staphylococcus aureus leads to high extracellular levels of glutamate, aspartate, γ-aminobutyric acid, and zinc
Hassel, Bjørnar; Dahlberg, Daniel; Mariussen, Espen; Goverud, Ingeborg Løstegaard; Antal, Ellen-Ann; Tonjum, Tone; Mæhlen, Jan (2014)Staphylococcal brain infections may cause mental deterioration and epileptic seizures, suggesting interference with normal neurotransmission in the brain. We injected Staphylococcus aureus into rat striatum and found an ... -
Capacities of metabotropic glutamate modulators in counteracting soman-induced seizures in rats
Myhrer, Trond; Mariussen, Espen; Enger, Siri; Aas, Pål (2013)The mechanisms underlying insulin sensitivity and fat tissue distribution in chronic renal insufficiency remain unclear. Previous studies have shown the benefits of angiotensin II receptor blockers on moderately nourished ... -
Development of neuropathology following soman poisoning and medical countermeasures
Myhrer, Trond; Mariussen, Espen; Aas, Pål (2018)Nerve agent-induced seizures can cause varying degrees of neuropathology depending on level of poisoning and duration of seizing. The intention of this review was to validate a novel approach for establishing effective ... -
Distribution and mobility of lead (Pb), antimony (Sb) and copper (Cu) from ammunition residues on shooting ranges for small arms located on mires
Mariussen, Espen; Johnsen, Ida Vaa; Strømseng, Arnljot Einride (2017)An environmental survey was performed on shooting ranges for small arms located on minerotrophic mires. The highest mean concentrations of Pb (13 g/kg), Cu (5.2 g/kg), Zn (1.1 g/kg), and Sb (0.83 g/kg) in the top soil were ... -
Glioblastoma microenvironment contains multiple hormonal and non-hormonal growth-stimulating factors
Dahlberg, Daniel; Rummel, Jutta; Distante, Sonia; De Souza, Gustavo Antonio; Stensland, Maria; Mariussen, Espen; Rootwelt, Helge; Voie, Øyvind Albert; Hassel, Bjørnar (2022-06-04)Background The growth of malignant tumors is influenced by their microenvironment. Glioblastoma, an aggressive primary brain tumor, may have cysts containing fluid that represents the tumor microenvironment. The aim of ... -
Neurotoxic effects of perfluoroalkylated compounds: mechanisms of action and environmental relevance
Mariussen, Espen (2012)Perfluoroalkylated compounds (PFCs) are used in fire-fighting foams, treatment of clothes, carpets and leather products, and as lubricants, pesticides, in paints and medicine. Recent developments in chemical analysis have ... -
Risk Assessment of Sea Dumped Conventional Munitions
Voie, Øyvind Albert; Mariussen, Espen (2016)Energetic compounds from dumped ammunition are toxic to aquatic organisms. Leakage of ammunition residues will occur when the bombshells are broken and the energetic compounds come into contact with water. The munitions ... -
Selective adsorption of lead, copper and antimony in runoff water from a small arms shooting range with a combination of charcoal and iron hydroxide
Mariussen, Espen; Johnsen, Ida Vaa; Strømseng, Arnljot Einride (2015)Metals and metalloids from ammunition residues at small arms shooting ranges leach into the soil and surrounding watercourses and may pose a threat to exposed wildlife and humans. To reduce the potential impact of heavy ... -
Supralethal poisoning by any of the classical nerve agents is effectively counteracted by procyclidine regimens in rats
Myhrer, Trond; Mariussen, Espen; Enger, Siri; Aas, Pål (2015)A treatment regimen consisting of HI-6, levetiracetam, and procyclidine (termed the triple regimen) has previously been shown to work as a universal therapy against soman poisoning in rats, since it has capacities to ... -
A survey of dioxin-like contaminants in fish from recreational fishing
Heimstad, Eldbjørg Sofie; Grønstøl, Gaute; Hetland, Karl Torstein; Alarcon, Javier Martinez; Rylander, Charlotta; Mariussen, Espen (2015)The dioxin and dioxin-like compounds are regarded as one of the most toxic group of environmental contaminants. Food for the commercial market is regularly monitored for their dioxin levels and the concentration allowed ... -
Toxic effects of gunshot fumes from different ammunitions for small arms on lung cells exposed at the air liquid interface
Mariussen, Espen; Fjellbø, Lise Marie; Frømyr, Tomas Roll; Johnsen, Ida Vaa; Karsrud, Tove Engen; Voie, Øyvind Albert (2021-01-14)Concerns have been raised as to whether gunshot fumes induce prolonged reduced lung capacity or even cancer due to inhalation. Gunshot fumes from three different types of ammunition calibre 5.56 mm × 45 NATO were investigated. ... -
Two medical therapies very effective shortly after high levels of soman poisoning in rats, but only one with universal utility
Myhrer, Trond; Enger, Siri; Mariussen, Espen; Aas, Pål (2013)A treatment regimen consisting of HI-6, scopolamine, and physostigmine (termed the physostigmine regimen) has been based on the serendipitous discovery that it exerts powerful antidotal effects against high levels of soman ... -
