BACKGROUND Increased thrombogenicity and smooth muscle cell proliferative response induced by the metal struts compromise the advantages of coronary stenting. The objective of this randomized, multicenter study was to assess whether a reduced strut thickness of coronary stents is associated with improved follow-up angiographic and clinical results. METHODS AND RESULTS A total of 651 patients ...

BACKGROUND Lack of re-endothelialization and neointimal coverage on stent struts has been put forward as the main underlying mechanism leading to late stent thrombosis. Incomplete stent apposition (ISA) has been observed frequently in patients with very late stent thrombosis after drug eluting stent implantation, suggesting a role of ISA in the pathogenesis of this adverse event. The aim of thi...

The influence of the in-stream pylon and strut on the performance of scramjet combustor was experimentally and numerically investigated. The experiments were conducted with a direct-connect supersonic model combustor equipped with multiple cavities. The entrance parameter of combustor corresponds to scramjet flight Mach number 4.0 with a total temperature of 947 K. The research results show tha...

Given a lattice Λ ⊂ R, a cylinder anchored at two lattice points is called a strut (or Λ-strut to be precise) if its interior does not contain a lattice point. We are interested in determining the maximum radius for a strut of given length. Optimal Z-struts are constructed for n = 3, 4. We also derive, through a non-constructive but elementary argument, an achievable upper bound on the product ...

Due to the scarcity of rational models for predicting the strength of RC beam-column sandwich joints, a modified simplified softened strut-and-tie model suggests a more rational calculation method for the effective compressive strength and the height of the joint concrete based on the simplified softened strut-and-tie. The shear strength of existing tested 15 sandwich interior joints is calcula...

The roll center is one of the key parameters for designing a suspension. Several driving characteristics are affected significantly by the migration of the roll center during the suspension’s motion. The strut/SLA (strut/short-long-arm) suspension, which is widely used in production cars, combines the space-saving characteristics of a MacPherson strut suspension with some of the preferred handl...

AIM Percutaneous coronary intervention (PCI) for severe calcified lesions is still challenging, and there are few studies of drug-eluting stent (DES) implantation for severe calcified lesions, especially regarding long-term results and hemodialysis patients. The study purpose was to clarify the factors, including DES strut thickness, that affect the long-term outcome of severe calcified lesion ...

OBJECTIVES/HYPOTHESIS The maxillary strut is the bone that separates the foramen rotundum and superior orbital fissure. Tumors involving the lateral wall of the sphenoid sinus, posterior ethmoid, or posterior maxillary sinus may invade this region. The authors detail the anatomy of the strut and present a case series that emphasizes the importance and utility of this useful landmark during an e...

OBJECTIVES This study sought to evaluate the relationship between post-stent strut apposition and follow-up strut coverage using contour plot optical coherence tomographic analysis. BACKGROUND Tracking the fate of interested regions of struts at different time points has not been investigated. METHODS Post-intervention and 6-month follow-up optical coherence tomographic evaluations were per...
