PURPOSE To understand how hydrodynamic and morphologic changes in the aqueous humor outflow pathway contribute to decreased aqueous humor outflow facility after acute elevation of intraocular pressure (IOP) in bovine eyes. METHODS Enucleated bovine eyes were perfused at 1 of 4 different pressures (7, 15, 30, 45 mm Hg) while outflow facility was continuously recorded. Dulbecco PBS + 5.5 mM glu...

in the turfgrass industry, the need for salinity tolerant turfgrasses is increasing because of the increased use of saline and non-potable water. greenhouse container experiments were conducted to determine the relative salinity tolerance and growth responses of eleven native populations of tall fescue (festuca arundinacea schrub) (tf), including: semirom, mashhad, sanandaj, yasuj, yazd abad, d...

The purpose of this study was to compare numerical simulation data derived from finite element analysis (FEA) to experimental data on mini-implant loading. Nine finite element (FE) models of mini-implants and surrounding bone were derived from corresponding experimental specimens. The animal bone in the experiment consisted of bovine rib. The experimental groups were based on implant type, leng...

The present study successfully developed orally deliverable multimodular zinc (Zn) iron oxide (Fe3O4)-saturated bovine lactoferrin (bLf)-loaded polymeric nanocapsules (NCs), and evaluated their theranostic potential (antitumor efficacy, magnetophotothermal efficacy and imaging capability) in an in vivo human xenograft CpG-island methylator phenotype (CIMP)-1(+)/CIMP2(-)/chromosome instability-p...

Studies of the microstructure, phase composition and mechanical characteristics, namely microhardness metal–ceramic composites made Fe 90 wt.%–Cu 10 wt.% powder hydroxyapatite (Fe-Cu-HA), are presented in manuscript. The composite material was obtained using additive manufacturing based on 3D-printing method, with different content levels (40, 45 50%) polymer parts (60, 55 50%). It is shown tha...

Bu çalışmanın amacı, bazı çeltik çeşitlerinde toksik düzeyde demir içerikli tam besin çözeltisi uygulamasının taze yapraklarda glutatyon redüktaz ve askorbat peroksidaz aktiviteleri üzerine etkisini belirlemektir. Kum kültüründe yetiştirilen çeşitlerine sülfat (FeSO4.7H2O) formunda; I) 0, II) 45 µM Fe (yeterli Fe), III) 3.50 mM (toksik IV) + bentonitli ortam) şeklinde olmak üzere dört farklı mu...

Two regional finite element (FE) models of a buried glass-fiber reinforced composite pipe have been developed at the National University of Singapore (NUS). The model replicates an arbitrary site whereby fuel is being transported through the 400 mm diameter line, and comprises of multiple components such as the valve pit, 45 degrees and 90 degrees pipe bends, and a service road consisting of th...

OBJECTIVE The purpose of this study was to evaluate the accuracy of CT angiography with volume rendering for quantifying vascular stenoses in vitro. MATERIALS AND METHODS Vascular models with three degrees of stenosis (33%, 67%, and 83%) were imaged at three orientations to the axial plane (parallel, perpendicular, or 45 degrees ) using helical CT with 2-mm collimation and two pitches (1 or 2...

PURPOSE To characterize scleral biomechanics in both eyes of eight monkeys in which chronic intraocular pressure (IOP) elevation was induced in one eye. METHODS Each posterior sclera was mounted on a pressurization apparatus, IOP was elevated from 5 to 45 mm Hg while the 3D displacements of the scleral surface were measured by speckle interferometry. Finite element (FE) models of each scleral...
