  • The role of adrenoceptors in the central nervous system in male and female rat sexual behavior 

    Snoeren, Eelke (Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2014-09-10)
    Three different phases can be distinguished in rats’ sexual cycle, the introductory (precopulatory), the copulatory and the executive (ejaculatory) phases. In this review, a new analysis of existing pharmacological data is made, both in male and female rats, in which the different aspects of sexual behavior are taken into account. An effort is made to distinguish pharmacological effects on sexual ...
  • Hjemmedødens lovlighet 

    Wackers, Ger (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-20)
    <i>Den døendes rom</i> er kanskje et av de mest private rommene vi kjenner til; hjemme sannsynligvis i enda større grad enn i sykehus eller sykehjem. Også det som skjer innenfor det private territoriet av den døendes rom hjemme, skal være innenfor lovens rammer. En <i>post hoc</i> vurdering av et dødsfalls lovlighet, gjennom en dødsattest, er ikke tilstrekkelig. Hjemmedødens lovlighet må også sikres ...
