University of Waterloo’s Professor Qing-Bin Lu has discovered a large, all-season ozone hole in the lower stratosphere over the tropics (30 deg N – 30 deg S). The depth of this tropical ozone hole is comparable to that of the well-known springtime ozone hole over Antarctica, while its area is about seven times that of the latter. Qing-Bin Lu reveals a new ozone hole that exists in the lower stratosphere over the tropics across the seasons...

Schematic overview of the mechanism of action of the implemented snake venom proteins. Ecarin, a procoagulant snake venom protein bypasses the activation of series of clotting factors via intrinsic and extrinsic clotting pathway and directly activates prothrombin to thrombin thereby producing a fibrin blood clot. Once the clot is formed, clot breakdown (fibrinolysis) is initiated by the activation of plasminogen mainly by tissue plasminogen activator (tPA), forming active plasmin which proteolytically acts on the fibrin blood clot. Textilinin, an antifibrinolytic snake venom protein binds to plasmin with high specificity and inhibits the action of plasmin, stabilizing the fibrin blood clot.
