Knowledge Architecture
BHOC Knowledge Updates timeline launched
The BHOC authority hub now keeps only the three latest significant updates, while this dedicated index preserves the complete chronological record and related internal links.
BHOC Knowledge Updates
What changed, and when.
A chronological record of significant additions to BHOC science, evidence, research concepts, publications and knowledge architecture. This page preserves the history after items rotate out of Latest BHOC Knowledge Updates.
Scope: this timeline records meaningful public knowledge additions and substantial scientific or structural revisions. Routine styling, maintenance, deployment and minor SEO fixes are intentionally excluded.
October 2026
Evidence Library
Approved transplant evidence record PMID 38396887 added
The live evidence library was expanded with an approved source-linked transplantation record and refreshed evidence counts.
Scientific Commentary
One RBC Unit Is Not a Fixed Hemoglobin Dose
A source-linked scientific commentary examined hemoglobin-dose variability in RBC components, standards and interpretation of transfusion outcomes.
Related Scientific Evidence
Hypoxic RBC storage and oxygen delivery in human kidneys
A 2026 ex vivo human-kidney study was added as related evidence connecting RBC storage conditions with organ-level oxygen handling. No BHOC intervention was tested.
BHOC Definition
Product-specific HBOC evidence clarified
The BHOC definition chapter was expanded to state explicitly that investigational HBOCs differ in source, purification, molecular modification, formulation and oxygen-delivery behavior, and that findings for one formulation cannot establish another.
September 2026
Historical Veterinary Evidence
Veterinary real-world data connected to historical sources
Oxyglobin historical case reports and clinical archive links were added to the source-linked historical evidence structure.
Historical Perspective
Levien 2006 historical South Africa perspective published
A source-linked historical perspective was added to connect the South African Hemopure record with the evolution from broad blood-replacement language toward oxygen-delivery function.
AEO & Entity Definition
Direct BHOC definition added before the Knowledge Map
The authority hub gained a concise direct-answer definition of BHOC and aligned structured data to strengthen entity clarity for people and search/AI systems.
Historical Source Record
Navy–Biopure RESUS historical source note published
A source-grounded 2005 U.S. Navy–Biopure RESUS record was added with SEO and historical context for HBOC-201 research.
BHOC Purpose
Why BHOC refined around controlled oxygen delivery
The Why BHOC chapter was revised to emphasize product characterization and controlled oxygen-delivery function rather than a generic blood-replacement proposition.
Preprint
BHOC and Precision Oxygen Therapeutics preprint announced
The publication update connected the formal BHOC definition and the function-first Precision Oxygen Therapeutics concept to the public authority structure.
Application Knowledge
Military & Disaster Medicine application page published
A dedicated application page was added for prolonged casualty care, austere conditions and military/disaster oxygen-delivery context.
Knowledge Architecture
14-topic BHOC Knowledge Map and full chapters published
The authority hub was reorganized into a navigable topic cluster with dedicated chapters while preserving old anchors, approved source material and SEO continuity.
Evidence Watch
Function-based oxygen-delivery Evidence Watch published
Emergency-care and donor-blood access evidence was connected to the scientific question of supporting oxygen-delivery function when blood is delayed or unavailable.
Research Concept · Hypothesis
Size, Compartmentalization & Vascular Control
A testable concept connected molecular scale, red-cell compartmentalization, nitric-oxide kinetics, vascular response, microcirculation and tissue oxygen delivery.
Historical Evolution
Historical Evolution established as a dedicated BHOC authority chapter
The historical path from transfusion and blood banking through artificial oxygen carriers and HBOCs was consolidated into a source-linked authority section.
Research Concept · Hypothesis
Oxygen-Delivery Potency vs Hemoglobin Concentration
A research concept asked whether functional oxygen-delivery potency should be measured rather than inferred from hemoglobin concentration alone.
BHOC Authority
Central BHOC definition and terminology authority page created
The site established a central definition of BHOC as Biological Hemoglobin Oxygen Carrier and began consolidating terminology, historical HBOC language and Precision Oxygen Therapeutics around one authority hub.
