    • Longitudinal Evidence for Smaller Hippocampus Volume as a Vulnerability Factor for Perceived Stress 

      Lindgren, Lenita; Bergdahl, Jan; Nyberg, Lars (Journal article; Tidsskriftartikkel; Peer reviewed, 2016)
      Hippocampal volume has been found to be smaller in individuals with stress-related disorders, but it remains unclear whether smaller volume is a consequence of stress or rather a vulnerability factor. Here, we examined this issue by relating stress levels to hippocampal volumes in healthy participants examined every 5 years in a longitudinal population-based study. Based on scores of 25- to ...

    • Five-minute Apgar score ≤ 5 and molar incisor hypomineralisation (MIH) - a case control study 

      Sidaly, Rivan; Schmalfuss, Andreas Jørn; Skaare, Anne B; Sehic, Amer; Stiris, Tom; Espelid, Ivar (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-07-22)
      Background: The aetiology of molar incisor hypomineralisation (MIH) is unclear. The asymmetric distribution of MIH in the dentition may indicate that an insult of short duration that affects ameloblasts at a vulnerable stage could be a causative factor. Apgar ≤ 5 at 5 min may indicate asphyxia (hypoxic-ischemic insult) during birth. It was hypnotised that low Apgar score during birth may cause MIH. ...
