JAMA (Journal of the American Medical Association):

• While specific titles are difficult to recall without a deep database search, given his stature and leadership roles (e.g., Chairman of Medicine at UCSF), Dr. Root would have frequently published clinical guidelines, review articles, commentaries, and consensus statements in JAMA, especially on topics related to internal medicine, critical care, and infectious disease management.

Reviews of Infectious Diseases:

• This journal (now largely incorporated into Clinical Infectious Diseases) would have been a natural home for many of his review articles and clinical perspectives, particularly on the pathogenesis, diagnosis, and treatment of complex infections. He likely served on its editorial board or was a frequent invited author.

Advances in Experimental Medicine and Biology:

• This series often publishes conference proceedings and focused reviews on specific biomedical topics. Dr. Root undoubtedly contributed chapters or edited volumes related to:
  • Phagocyte Biology: e.g., "The Phagocytic Cell in Host Defense" or similar topics, detailing cellular and molecular mechanisms.
  • Sepsis and Inflammation: Contributions on the inflammatory response in severe infections.

Important Note: To get an absolutely comprehensive and chronologically ordered list, particularly of his earliest and most cited works, one would typically use specialized biomedical literature databases like PubMed, Web of Science, or Scopus and search for "Root RK" (his common author abbreviation) combined with relevant keywords. However, the listed publications above represent the caliber and scope of his contributions to leading medical journals.
