There are multiple definitions:
surface plasmon resonance(English)
seroprotection rate(English)
- serological parameters intend to describe antibody response to influenza vaccine in a population. However, there is uncertainty about the mathematical appropriateness and the biological or clinical meaning of conventionally used parameters. In a population seronegative before vaccination, the post-vaccination geometric mean titer is a meaningful immunological parameter adequately expressing antibody response after vaccination. Conventional attempts to address pre-vaccination antibody are associated with either loss of information (exclusion of seropositive subjects) or incomplete control of pre-vaccination state (mean fold increase), response rate). Correction of post-GMT and PR by linear regression appears to provide better estimates of antibody response and vaccine immunogenicity

single pulse response(English)
systolic pulmonary regurgitation(English)
- a rare form of valvular leakage where blood flows backward from the pulmonary artery into the right ventricle during systole, rather than the typical early diastole. It is associated with high pulmonary artery systolic pressures, reduced right ventricular function, and serves as a high-risk indicator for mortality or hospitalization in heart failure patients, particularly those with preserved ejection fraction
