Percutaneous coronary intervention in the elderly: changes in case-mix and periprocedural outcomes in 31758 patients treated between 2000 and 2007 [PDF]

open access: yes, 2010
<p>Background: The elderly account for an increasing proportion of the population and have a high prevalence of coronary heart disease. Percutaneous coronary intervention (PCI) is the most common method of revascularization in the elderly.

Investigating the Spillover Mechanisms of Payment Incentives on the Outcomes for Non‐Targeted Patients

open access: yesHealth Economics, EarlyView.
ABSTRACT Payment reforms in healthcare can have spillover effects on the care experienced by non‐targeted patients treated by the same provider. Few empirical studies have quantitatively investigated the mechanisms behind these effects. We formulate theory‐driven hypotheses to investigate the spillover mechanisms of a regional payment reform in the ...

Transfer and Development Length of Prestressing Tendons in Full-Scale AASHTO Prestressed Concrete Girders Using Self-Consolidating Concrete [PDF]

open access: yes, 2009
Self-consolidating concrete (SCC) is a highly workable concrete that flows through densely reinforced or complex structural elements under its own weight. The benefits of using SCC include: a) Reducing labor costs by eliminating the need for mechanical

Microvascular dysfunction in the immediate aftermath of chronic total coronary occlusion recanalization [PDF]

open access: yes, 2016
Objectives The aim of this study was to compare microvascular resistance under both baseline and hyperemic conditions immediately after percutaneous coronary intervention (PCI) of a chronic total occlusion (CTO) with an unobstructed reference vessel in ...

Downconversion Master Slave OCT With a Bidirectional Sweeping Laser

open access: yesJournal of Biophotonics, EarlyView.
ABSTRACT This paper explores the challenges of signal processing when using optical coherence tomography (OCT) imaging instruments driven by asymmetric MHz bidirectional sweeping lasers. A downconversion master–slave (DMS) method is proposed as a viable alternative to the traditional OCT protocol.

Improved and Automated Detection of Papillary Muscle Infarction Using Joint Bright‐ and Black‐Blood Late Gadolinium Enhancement MRI

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Papillary muscle infarction (PMI) has been linked to significantly increased mortality and is associated with ventricular arrhythmias and mitral regurgitation. Reference bright‐blood late gadolinium enhancement (LGE) imaging provides poor scar‐to‐blood contrast, making PMI visualization challenging. Black‐blood LGE imaging overcomes

Participatory crop improvement: the challenges of and opportunities for institutionalisation in the Indian public research sector [PDF]

open access: yes, 2014
This thesis considers Participatory Crop Improvement (PCI) methodologies and examines the reasons behind their continued contestation and limited mainstreaming in conventional modes of crop improvement research within National Agricultural Research ...

Tailorable Nanoparticles for Magnetic Water Cleaning of Polychlorinated Biphenyls

open access: yesSmall Methods, EarlyView.
Polychlorinated biphenyls (PCBs) are human‐made persistent organic pollutants omnipresent in the earth's hydrosphere, which are reported hazardous to humans as well as wildlife. This study presents surface functionalized magnetic nanoparticles that can remove such contaminants from water with an adjustable preference for most concerning compounds ...

Photocarrier injection and the I-V characteristics of La0.8Sr0.2MnO3/SrTiO3:Nb heterojunctions

open access: yes, 2004
Oxide heterojunctions made of p-type L0.8Sr0.2MnO3 (LSMO) and niobium-doped n-type SrTiO3 (STO:Nb) have been fabricated by the pulsed laser deposition (PLD) technique and are characterized under UV light irradiation by measuring the current-voltage ...
