Abstract: The present invention provides a method for inducing angiogenesis at a target locus in a mammal using morphogenic proteins. In addition, this invention also features a method for improving the angiogenic capability of a morphogenic protein at a target locus in a mammal. In this method, the morphogenic protein is capable of inducing angiogenesis when accessible to a progenitor cell in the mammal, and the morphogenic protein stimulatory factor enhances that capability. The morphogenic protein and morphogenic protein stimulatory factor can be administered simultaneously to the target locus. Alternatively, the two components are administered separately, in any order.

IPC: G06F/
Filed: 2002-12-10
Abstract: A method for raising awareness of sustainable development issues involves the identification of a number of indicators which are representative of the sustainability issues relating to an activity, for example an industrial or infrastructural development activity. Data relevant to each of the indicators is collected and analyzed, and a value is then assigned to each indicator which is based on the collected data. The indicator values are then converted to indicator scores which may be either qualitative or quantitative, in order to determine to overall impact of the activity on sustainability. The analysis can be repeated over time to determine the overall impact of the activity on sustainability, and the results can be aggregated to monitor an organization's progress toward sustainability.
