An Atlantic cod (Gadus morhua L.) pituitary model system for reproductive and reprotoxic testing in vitro
von Krogh, Kristine (PhD Thesis;2021:14, Doctoral thesis, 2021)Due to factors such as overfishing, climate changes and pollution, most fish stocks are in decline. This is also the case for the commercially important marine species, Atlantic cod (Gadus morhua). As a result, the last ... -
Cocktails of persistent organic pollutants lead to behavioural and reproductive toxicity
Khezri, Abdolrahman (PhD thesis;2017:30, Doctoral thesis, 2017)Persistent organic pollutants (POPs) are chemicals that widely distributed in the environment and biota that could cause neurobehavioural and reproductive toxicity. As humans and animals are exposed to a complex mixture ... -
Effects of persistent organic pollutants (POPs) on the steroidogenesis of primary neonatal porcine Leydig cells
Bjørklund, Cesilie Granum (PhD thesis;2019:7, Doctoral thesis, 2019)After World War II the production of manmade chemicals has increased immensely. They are made to give desired practical properties and functions. Some are added to consumer products to provide conductivity, increase flame ... -
Exploring the short and long-term effects of developmental exposure in zebrafish exposed to anthropogenic chemicals
Christou, Maria (PhD Thesis;2020:44, Doctoral thesis, 2020)Persistent organic pollutants (POPs) are anthropogenic chemicals omnipresent in the environment and animal tissues. Due to their persistency they are rarely found as single compounds within organisms but rather in complex ... -
Neurodevelopmental toxicity of a human relevant mixture of persistent organic pollutants (POPs) and perfluorooctane sulfonic acid (PFOS)
Yadav, Ajay (PhD Thesis;2021:63, Doctoral thesis, 2021)Persistent organic pollutants (POPs) are ubiquitous in the environment. Humans are continuously exposed to chemical mixtures through food and the environment. Exposure to POPs have been associated with several adverse ... -
Persistent organic pollutants and effects on developmental and functional processes in mice
Johanson, Silje Modahl (PhD Thesis;2020:45, Doctoral thesis, 2020)Initial exposure to persistent organic pollutants (POPs) occurs by placental and lactational transfer during fetal and neonatal life and continues during the adult stage through ingestion, inhalation and dermal absorption. ... -
Reproductive potential and quality of SpermVital semen used for artificial insemination in cattle
Berg, Halldor Felde (PhD thesis;2020:17, Doctoral thesis, 2020)Utfallet av kunstig sædoverføring (KS) avhenger av flere faktorer, blant annet sædkvalitet, metoden for sædprosessering og miljøet i kjønnsorganet hos det inseminerte hunndyret. Vellykket KS hos storfe krever også riktig ... -
Studies of boar taint, with an emphasis on testicular function and development
Lervik, Siri (PhD Thesis;2015:43, Doctoral thesis, 2015)Boar taint is an odour reminiscent of sweat, urine or faeces, perceived as off-flavour when meat from entire male swine is heated. The compunds that cause boar taint are androstenone and skatole/indole. Androstenone is ... -
Vaginal Temperature and Activity Variations in Relation to Fecal Progestagens of Captive Moose (Alces alces)
Høy-Petersen, Jennifer (Student paper, others, 2022)Accurate detection of specific reproductive events presents a challenge to scientists studying wild species, including moose. There are several established methods for monitoring reproductive activity in domestic ruminants, ...
