At thallium imaging, 91 (33%) segments had normal uptake, 16 (6%) showed reversible defects, and the remaining 166 (61%) irreversible defects.
Of these 166 irreversible defects, 74 (45%) had moderate (≥58% of peak activity) and 92 (55%) severe (<58% of peak activity) reduction of thallium uptake.
Of particular interest for the treatment of inherited retinal degenerations, subretinal delivery of these nanoparticles transfected nearly all of the photoreceptor population and did not cause irreversible defects in retinal function (as measured by electroretinogram (ERG)) [14].
The isolated atg7 −/− keratinocytes may have acquired irreversible defects before treatment, potentially influencing the experimental outcome.
Perfusion defect (segmental tracer activity <50% of maximum) was identified on the stress image first and was divided into ischemia (reversible defects: >10% increase in tracer uptake on the rest image compared with stress image) or scar (irreversible defects).
Significant predictors of future coronary events after pharmacologically induced stress MPI include large defects, defects in multiple coronary artery territory suggestive of multi-vessel disease, major irreversible defects, left ventricular dilatation and decreased resting left ventricular ejection fraction [ 86].
38, 40 This could be attributed to excess damage of RGO flakes caused at the harsh environment in the autoclave during the vigorous process of reduction hybridization and to irreversible defects induced during the oxidation process of initial graphite powder.
This points to crucial, early developmental events dependent on Mpi and suggests that an absence of mannose supplementation early in development might manifest later as defects, including irreversible defects such as liver fibrosis, that are actual consequences of early Mpi dysfunction.
