Aims: To evaluate the implications of an Absorb bioresorbable vascular scaffold (Absorb BVS) on the morphology of the superficial plaques. Methods and results: Forty-six patients who underwent Absorb BVS implantation and 20 patients implanted with bare metal stents (BMS) who had serial optical coherence tomographic examination at baseline and follow-up were included in this analysis. The thin-capped fibroatheromas (TCFA) were identified in the device implantation regions and in the adjacent native coronary segments. Within all regions, circumferential locations of TCFA and calcific tissues were identified, and the neointimal thickness was measured at follow-up. At six to 12-month follow-up, only 8% of the TCFA detected at baseline were still present in the Absorb BVS and 27% in the BMS implantation segment (p=0.231). Sixty percent of the TCFA in native segments did not change their phenotype at follow-up. At short-term follow-up, significant reduction in the lumen area of the BMS was noted, which was higher compared to that reported in the Absorb BVS group (-2.11±1.97 mm2 vs. -1.34±0.99 mm2, p=0.026). In Absorb BVS, neointima tissue continued to develop at midterm follow-up (2.17±0.48 mm2 vs. 1.38±0.52 mm2, p<0.0001) and covered the underlying tissues without compromising the luminal dimensions (5.93±1.49 mm2 vs. 6.14±1.49 mm2, p=0.571) as it was accommodated by the expanded scaffold (8.28±1.74 mm2 vs. 7.67±1.28 mm2, p<0.0001). Conclusions: Neointimal tissue develops following either Absorb BVS or BMS implantation and shields lipid tissues. The neointimal response in the BMS causes a higher reduction of luminal dimensions compared to the Absorb BVS. Thus, Absorb BVS may have a value in the invasive re-capping of high-risk plaques.

UNLABELLED Adenovirus dodecahedron (Dd), a nanoparticulate proteinaceous biodegradable virus-like particle (VLP), was used as a vector for delivery of an oncogene inhibitor to hepatocellular carcinoma (HCC) rat orthotopic model. Initiation factor eIF4E is an oncogene with elevated expression in human cancers. Cell-impermeant eIF4E inhibitor, cap structure analog (cap) and anti-cancer antibiotic doxorubicin (Dox) were delivered as Dd conjugates. Dd-cap and Dd-dox inhibited cancer cell culture proliferation up to 50 and 84%, respectively, while with free Dox similar results could be obtained only at a 5 times higher concentration. In animal HCC model the combination treatment of Dd-cap/Dd-dox caused 40% inhibition of tumor growth. Importantly, the level of two pro-oncogenes, eIF4E and c-myc, was significantly diminished in tumor sections of treated rats. Attachment to Dd, a virus-like particle, permitted the first demonstration of cap analog intracellular delivery and resulted in improved doxorubicin delivery leading to statistically significant inhibition of HCC tumor growth. FROM THE CLINICAL EDITOR Adenovirus dodecahedron, a nanoparticulate proteinaceous biodegradable virus-like particle was used in this study as a vector for the concomitant delivery of cap structure analog and doxorubicine to hepatocellular carcinoma in a rat model, resulting in significant inhibition of tumor growth.
