      Raatiniemi, Lasse; Steinvik, Tine; Liisanantti, Janne; Ohtonen, Pasi; Martikainen, Matti; Alahuhta, Seppo; Dehli, Trond; Wisborg, Torben; Bakke, Håkon Kvåle (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-01-08)
      Background: Finland has the fourth highest injury mortality rate in the European Union. To better understand the causes of the high injury rate, and prevent these fatal injuries, studies are needed. Therefore, we set out to complete an analysis of the epidemiology of fatal trauma, and any contributory role for alcohol, long suspected to promote fatal injuries. As a study area, we chose the ...

    • Peripheral chemoreflex activation and cardiac function during hypoxemia in near-term fetal sheep without placental compromise 

      Lantto, Juulia; Erkinaro, Tiina; Haapsamo, Mervi; Huhta, Heikki; Alanne, Leena; Kokki, Merja; Ohtonen, Pasi; Bhide, Amarnath; Acharya, Ganesh; Rasanen, Juha (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-09)
      A drop in arterial oxygen content activates fetal chemoreflex including an increase in sympathetic activity leading to peripheral vasoconstriction and redistribution of blood flow to protect the brain, myocardium, and adrenal glands. By using a chronically instrumented fetal sheep model with intact placental circulation at near-term gestation, we investigated the relationship between peripheral ...
