Scenario simulations of future salinity and ecological consequences in the Baltic Sea and adjacent North Sea areas-implications for environmental monitoring.

Substantial ecological changes occurred in the 1970s in the Northern Baltic during a temporary period of low salinity (S). This period was preceded by an episodic increase in the rainfall over the Baltic Sea watershed area. Several climate models, both global and regional, project an increase in the runoff of the Northern latitudes due to proceeding climate change.

Four-millimeter implants supporting fixed partial dental prostheses in the severely resorbed posterior mandible: two-year results.

Background: Reduced alveolar bone volume complicates implant dentistry.

Purpose: In this prospective multicenter study, a new, 4-mm long Straumann SLActive implant (Ø 4.1 mm) supporting a fixed dental prosthesis (FDP) in the severely resorbed posterior mandible was evaluated for two years.

Infiltration of morphine into an abnormal wound; effects on pain relief and endocrine/immune response.

We wanted to evaluate pain relief and endocrine/immune response after local administration of morphine into an abdominal wound. In a randomised double blind design 29 patients undergoing hysterectomy received two blinded injections of morphine and saline. Before surgery the patients in the control group (n = 15) got 10 mg of subcutaneous morphine into an arm and at skin incision 30 ml of saline was infiltrated directly into the wound.
