The missing pieces for better future predictions in subarctic ecosystems: A Torneträsk case study.

Arctic and subarctic ecosystems are experiencing substantial changes in hydrology, vegetation, permafrost conditions, and carbon cycling, in response to climatic change and other anthropogenic drivers, and these changes are likely to continue over this century. The total magnitude of these changes results from multiple interactions among these drivers. Field measurements can address the overall responses to different changing drivers, but are less capable of quantifying the interactions among them.

[The number and histopathologic type of ovarian tumors operated during cesarean section at the Polish Mother's Health Institute between 1990-2000].

Objectives: The differences exist in concerning the estimation of number and histopathological type of ovarian tumors in pregnancy.

Material And Methods: From all 41,661 labours which took place in our Institute between 1990-2000 retrospective analysis of medical documentation of 11,050 caesarean sections (CS) as well as histopathological protocols were performed.

Results: The prevalence of ovarian tumors removed during CS performed between 28-41 weeks of gestation was 0.
