Platelet Satellitism [PDF]

open access: yesBlood, 1974
Abstract Platelet adherence to polymorphonuclear leukocytes, or so-called platelet satellitism, has, to our knowledge, been reported in only four patients. We had the opportunity to study this phenomenon in two patients. Platelet satellitism was only seen in EDTA anticoagulated blood, and the platelets were seen to surround ...

Inferring viral quasispecies spectra from 454 pyrosequencing reads

open access: yesBMC Bioinformatics, 2011
Background RNA viruses infecting a host usually exist as a set of closely related sequences, referred to as quasispecies. The genomic diversity of viral quasispecies is a subject of great interest, particularly for chronic infections, since it can lead ...
