Whole genomes from the extinct Xerces Blue butterfly can help identify declining insect species.

The Xerces Blue () is considered to be the first butterfly to become extinct in historical times. It was notable for its chalky lavender wings with conspicuous white spots on the ventral wings. The last individuals were collected in their restricted habitat, in the dunes near the Presidio military base in San Francisco, in 1941.

Genetic data from the extinct giant rat from Tenerife (Canary Islands) points to a recent divergence from mainland relatives.

Evolution of vertebrate endemics in oceanic islands follows a predictable pattern, known as the island rule, according to which gigantism arises in originally small-sized species and dwarfism in large ones. Species of extinct insular giant rodents are known from all over the world. In the Canary Islands, two examples of giant rats, † and †, endemic to Tenerife and Gran Canaria, respectively, disappeared soon after human settlement.

Evolutionary History, Genomic Adaptation to Toxic Diet, and Extinction of the Carolina Parakeet.

As the only endemic neotropical parrot to have recently lived in the northern hemisphere, the Carolina parakeet (Conuropsis carolinensis) was an iconic North American bird. The last surviving specimen died in the Cincinnati Zoo in 1918 [1]. The cause of its extinction remains contentious: besides excessive mortality associated to habitat destruction and active hunting, their survival could have been negatively affected by its range having become increasingly patchy [2] or by the exposure to poultry pathogens [3, 4].

French lyophilized plasma versus fresh frozen plasma for the initial management of trauma-induced coagulopathy: a randomized open-label trial.

Unlabelled: Essentials An immediate supply of plasma in case of trauma-induced coagulopathy is required. The Traucc trial compared French Lyophilised Plasma (FLyP) and Fresh Frozen Plasma (FFP). FLyP achieved higher fibrinogen concentrations compared with FFP.

[Is the research of posttransfusional alloantibodies still relevant?].

Unlabelled: The decision of November 6th, 2006 defining the principles of best practices recommends that posttransfusional red cell alloantibodies research is performed after one to three months after. In the University hospital of Brest, the haemovigilance unit takes charge of sending the medical prescription within the required time and centralizing the results. We wished to estimate if the realization of this research still remains relevant.
