We provide a simple, semi-quantitative method to investigate biofilm formation in vitro. This method takes advantage of the Zeiss stemi 2000-C Dissecting Microscope (with camera attachment) to monitor both the timing and pattern of biofilm formation, as assessed by the development of wrinkled colonies.

We describe the reduction of reperfusion injury by 670 nm irradiation in a mouse model of ischemia and reperfusion by tourniquet placement. This 670 nm irradiation reduced the inflammatory response, decreased the number of proinflammatory macrophages, and increased the protective macrophages.
