: surgical cutting, shaping, and smoothing of the front or lower surface of the acromion to relieve compression of the rotator cuff between the acromion and head of the humerus when the arm is raised overhead In a procedure called acromioplasty, surgeons shave away some of the bone to make more room for the rotator cuff, in hopes of alleviating pain ...
FLUVIRINÂ® (Influenza Virus Vaccine) is an inactivated subunit influenza virus vaccine indicated for active immunization of persons aged 4 years and older against influenza disease caused by influenza virus subtypes A and B included in the vaccine.1.
Influenza is a lipid-enveloped, pleomorphic virus. We combine electron cryotomography and analysis of images of frozen-hydrated virions to determine the structural organization of filamentous influenza A virus. Influenza A/Udorn/72 virions are capsule-shaped or filamentous particles of highly uniform diameter.n the present study, we investigate the structural basis for filamentous morphology in influenza virus. Filamentous morphology is typical of clinical isolates of influenza virus, whereas a spherical morphology is observed in many laboratory-passaged influenza strains (18, 19).
