A large-scale groundwater contamination characterises the Pleistocene groundwater system of the former industrial and abandoned mining region Bitterfeld/Wolfen, Eastern Germany. For more than a century, local chemical production and extensive lignite mining caused a complex contaminant release from local production areas and related dump sites. Today, organic pollutants (mainly organochlorines) ...

Hemodialysis (HD)-induced myocardial ischemia is associated with an elevated cardiac troponin T, and is common in asymptomatic patients undergoing conventional HD. Remote ischemic preconditioning (RIPC) has a protective effect against myocardial ischemia-reperfusion injury. We hypothesized that RIPC also has a protective effect on HD-induced myocardial injury. Chronic HD patients were ...
