Planar V/Q, V/Q-SPECT, and Q-LDCT were all highly effective for diagnosing CTEPH, with no significant differences in sensitivity or specificity observed among the three techniques (Planar V/Q [sensitivity/specificity] 94.20%/92.81%; V/Q-SPECT 97.10%/91.37%, Q-LCDT 95.65%/90.65%). However, V/Q-SPECT was significantly more sensitive (V/Q-SPECT 79.21%; Planar V/Q 75.84%, P = 0.012; Q-LDCT 74.91%, p less then 0.001), and Planar V/Q was significantly more specific (Planar V/Q 54.14%; V/Q-SPECT 46.05%, p less then 0.001; Q-LDCT 46.05%, P = 0.001) than the other two techniques for identifying perfusion defects in individual lung segments. Conclusion Both Planar V/Q and V/Q-SPECT were highly effective for diagnosing CTEPH, and Q-LDCT may be a reliable alternative method for patients who are unsuitable for ventilation imaging.

Diatoms differ from the green lineage of oxygenic organisms by their photosynthetic pigments and light-harvesting complex (Lhc) proteins, the latter of which are also called fucoxanthin-chlorophyll proteins (FCP). These are composed of three groups of proteins Lhcf as the main group, Lhcr that are PSI-associated, and Lhcx that are involved in photoprotection. The FCP complexes are assembled in trimers and higher oligomers. Several studies have investigated the biochemical properties of purified FCP complexes, but limited knowledge is available about their interaction with the photosystem cores. In this study, isolation of stable supercomplexes from the centric diatom Thalassiosira pseudonana was achieved. To preserve in vivo structure, the separation of thylakoid complexes was perform
