PURPOSE To examine the mtDNA control regions in normal and age-related macular degeneration (AMD) retinas. To identify the mtDNA variations associated with AMD. METHODS Retinas from 10 normal and 11 AMD globes were isolated and analyzed for mtDNA rearrangements by long extension-polymerase chain reaction (LX-PCR) and for the nature and frequency of(More)
PURPOSE To determine whether keratoconus (KC) corneas have more mitochondrial (mt)DNA damage than do normal corneas. METHODS Thirty-three normal corneas and 34 KC corneas were studied. Immunohistochemistry for mitochondria-encoded cytochrome c oxidase (complex IV) subunit 1 (CO-Iota) and porins was performed. Total DNA was isolated and mtDNA genome(More)
— An important goal in multiobjective optimisation is to find a good set of non-dominated solutions that is both well-distributed and well-converged. Most multiobjective optimisation algorithms use the conventional Pareto dominance relationship. Over recent years, new approaches for the dominance relationship such as relaxed Pareto dominance, have been(More)
This paper proposes an improved version of volume dominance to assign fitness to solutions in Pareto-based multi-objective optimisation. The impact of this revised volume dominance on the performance of multi-objective evolutionary algorithms is investigated by incorporating it into three approaches, namely SEAMO2, SPEA2 and NSGA2 to solve instances of the(More)
OBJECTIVE The objective of this study was to determine whether advanced practice providers could learn to collect objective functional assessment data accurately and efficiently with commercially available devices that measure kinematics and kinetics (Nintendo Wii Balance Board [WBB] and Level Belt [LB]) to aid in the assessment of fall risk and outcomes(More)
BACKGROUND Laparoscopic Nissen fundoplication has become a mainstay in the surgical treatment of gastroesophageal reflux disease, as it has proved to be a durable, well-tolerated procedure. Despite the safety and efficacy associated with this procedure, surgeons performing this advanced laparoscopic surgery should be well versed in the potential(More)
Hemodynamic responses to cocaine vary greatly between animals, and the variability is related to the incidence of cocaine-induced cardiomyopathies and hypertension. The variability in cardiac output and systemic vascular resistance responses to cocaine in individuals is correlated with the responses to acute startle (air jet). This experiment was designed(More)
PURPOSE To identify inexpensive, noninvasive, portable, clinical assessment tools that can be used to assess functional performance measures that may put older patients at risk for falls such as balance, handgrip strength, and lumbopelvic control. PATIENTS AND METHODS Twenty fragility fracture patients and 21 healthy control subjects were evaluated using(More)
Fragility fractures, or fractures occurring from a low-trauma event, are extremely prevalent among the elderly population worldwide and associated with significant mortality and morbidity. This study evaluated the relationship between FES-I Fear of Falling Survey results, self-reported activity restrictions via the SF-36 survey, and scores recorded by(More)
