Nigella glandulifera seeds are used as a spice or remedy for the treatment of various inflammatory diseases. This study aimed to investigate analgesic (writhing test), anti-inflammatory (ear-induced edema, vascular permeability test), antioxidant, and antitumor activities of total saponins from this plant (TSN). TSN (6, 12, and 24 mg/kg) were exhibited analgesic and anti-inflammatory activities...

After the beginning of metal processing at the transition from the Neolithic to the Bronze Age, further knowledge of ore mining and smelting had spread from the Near East to central Europe. In the copper ore deposits of Schwaz, in the central part of the Alps, the oldest traces of copper mining derive from the early to middle Bronze Ages. Investigation of a middle to late Bronze Age (1410–920 c...
