BACKGROUND In-stent restenosis rates have been closely linked to the wall shear stress distribution within a stented arterial segment, which in turn is a function of stent design. Unfortunately, evaluation of hemodynamic performance can only be evaluated with long term clinical trials. In this work we introduce a set of metrics, based on statistical moments, that can be used to evaluate the hem...

PURPOSE We present a new morphometric measure of trabecular bone microarchitecture, called mean node strength (NdStr), which is part of a newly developed approach called long range node-strut analysis. Our general aim is to describe and quantify the apparent "latticelike" microarchitecture of the trabecular bone network. METHODS Similar in some ways to the topological node-strut analysis intr...

The vertical rotation method is a special option for steel tower construction in fabricated bridge. tall prefabricated on the ground and then pulled to its designed position using wires. Traditional always uses taller temporary structure provide an upward pull force lift member; however, would spend much time, cost, work high above ground. For instance, Jinwu Bridge tower’s weight was so heavy ...

To the Editor: Kastrati et al recently reported1 significantly less restenosis with lesions randomized to deployment of one stent design (ACS RX Multi-Link, [ML]) than with a related design (Multi-Link RX Duet, [DT]) from the same manufacturer (Guidant). They attributed the difference in restenosis to the difference in strut thickness. Although the two stent designs do differ significantly in s...

While older age associates with adverse percutaneous coronary intervention (PCI) outcomes, detailed information relating age to stent strut coverage and neointimal characteristics is lacking. One hundred nineteen patients with 123 sirolimus-eluting stents (SESs) were divided into 3 groups: group A (≤55 years), group B (56-65 years), and group C (>65 years). At 6 and 12 months of follow-up, opti...

OBJECTIVES/HYPOTHESIS Characterizing the mechanical properties of structural cartilage grafts used in rhinoplasty is valuable because softer engineered tissues are more time- and cost-efficient to manufacture. The aim of this study is to quantitatively identify the threshold mechanical stability (e.g., Young's modulus) of columellar, L-strut, and alar cartilage replacement grafts. STUDY DESIG...

PURPOSE To evaluate the effect of statin treatment on strut coverage after drug-eluting stent (DES) implantation. MATERIALS AND METHODS In this study, 60 patients were randomly assigned to undergo sirolimus-eluting stent (SES) or biolimus-eluting stent (BES) implantation, after which patients were randomly treated with pitavastatin 2 mg or pravastatin 20 mg for 6 months. The degree of strut c...

UNLABELLED We present a case of sternal steel strut dislodgement and migration in a patient undergoing Ravitch repair for pectus excavatum (PE) 37 years ago. Broken struts perforated the right ventricle and right ventricular outflow tract (RVOT) and additionally migrated into the left upper lobar bronchus.Dislodged sternal struts represent rare complications after surgical repair of patients su...

Enchondroma of the hand is a common lesion with a recurrence rate of up to 13.3% after curettage and bone grafting. Pathologic fractures often occur. Although allograft bone chips are widely used in the surgical treatment of enchondroma, the use of structural allograft bone has not been reported before. This case report presents a recurrent enchondroma of the fifth metacarpal with pathologic fr...
