Consensus guidelines for the use and interpretation of angiogenesis assays

The formation of new blood vessels, or angiogenesis, is a complex process that plays important roles in growth and development, tissue and organ regeneration, as well as numerous pathological conditions. Angiogenesis undergoes multiple discrete steps that can be individually evaluated and quantified by a large number of bioassays. These independent assessments hold advantages but also have limitations. This article describes in vivo, ex vivo, and in vitro bioassays that are available for the evaluation of angiogenesis and highlights critical aspects that are relevant for their execution and proper interpretation. As such, this collaborative work is the first edition of consensus guidelines on angiogenesis bioassays to serve for current and future reference

Hidatsa Social and Ceremonial Organization

This ethnographic paper, dated January 1, 1963, sponsored by the Smithsonian Institution Bureau of American Ethnology is a detailed description of Hidatsa Social and Ceremonial practices as told by ethnographer Alfred W. Bowers based on data collected in the 1930s. All the Hidatsa informants of this project were born about 1850-1860 and were alive at the time of the Custer massacre. Bowers indicates that he pushed informants to share sacred religious lore for the sake of this project. The paper is an extensive account of Hidatsa social organization, kinship systems, societies, ceremonies, and other details about the history and social practices as collected at the time. The paper includes illustrations, text figures, charts, photographs, and maps.https://commons.und.edu/indigenous-gov-docs/1109/thumbnail.jp
