Temporal trends of mercury levels in fish (dab, Limanda limanda) and sediment from the German Bight (North Sea) in the period 1995-2020.

As a toxic and harmful global pollutant, mercury (Hg) enters the marine environment through natural sources, and human activities. It bioaccumulates through the food chain and therefore, Hg is of great importance for environmental monitoring. This study aims to answer the question if Hg contamination in fish and sediment from the German Bight follows temporal trends.

The influence of limited postoperative weight-bearing on the outcome of drilling in osteochondritis dissecans tali.

Introduction: This prospective study was performed to assess the influence of limited weight-bearing on the outcome of osteochondral drilling in the treatment of an osteochondritis dissecans tali.

Materials And Methods: Of a total of 85 patients, 68 (80%; 37 male, 31 female, average age 28 years) were followed up after open or arthroscopic drilling between July 1990 and March 2000. The total outcome of 6 weeks limited postoperative weight-bearing (n=26) was compared with the outcome of 12 weeks limited weight-bearing (n=42).
