    • Fetal size in the second trimester is associated with the duration of pregnancy, small fetuses having longer pregnancies 

      Wilsgaard, Tom; Johnsen, Synnøve L.; Rasmussen, Svein; Hanson, Mark A.; Godfrey, Keith M.; Kiserud, Torvid (Journal article; Tidsskriftartikkel; Peer reviewed, 2008-07-16)
      Background: Conventionally, the pregnancy duration is accepted to be 280–282 days. Fetuses determined by ultrasound biometry to be small in early pregnancy, have an increased risk of premature birth. We speculate that the higher rate of preterm delivery in such small fetuses represents a pathological outcome not applicable to physiological pregnancies. Here we test the hypothesis that in ...

(Journal article; Tidsskriftartikkel; Peer reviewed, 2009-07-29)
      Background: Gonadotropin releasing hormone (GNRH1) triggers the release of follicle stimulating hormone and luteinizing hormone from the pituitary. Genetic variants in the gene encoding GNRH1 or its receptor may influence breast cancer risk by modulating production of ovarian steroid hormones. We studied the association between breast cancer risk and polymorphisms in genes that code for GNRH1 ...
