Characterization and genomic analysis of an oceanic cyanophage infecting marine Synechococcus reveal a novel genus

open access: yesFrontiers in Microbiology, 2023
Cyanophages play a crucial role in the biogeochemical cycles of aquatic ecosystems by affecting the population dynamics and community structure of cyanobacteria. In this study, a novel cyanophage, Nanhaivirus ms29, that infects Synechococcus sp. MW02 was

Evolution of triage systems [PDF]

open access: yesEmergency Medicine Journal, 2006
The French word "trier", the origin of the word "triage", was originally applied to a process of sorting, probably around 1792, by Baron Dominique Jean Larrey, Surgeon in Chief to Napoleon's Imperial Guard. Larrey was credited with designing a flying ambulance: the Ambulance Volante.
