A PET/MRI study towards finding the optimal [18F]Fluciclovine PET protocol for detection and characterisation of primary prostate cancer.
(Journal article; Peer reviewed, 2016)Purpose: [18F]Fluciclovine PET imaging shows promise for the assessment of prostate cancer. The purpose of this PET/MRI study is to optimise the PET imaging protocol for detection and characterisation of primary prostate ... -
A pig model of acute right ventricular afterload increase by hypoxic pulmonary vasoconstriction
(Journal article; Peer reviewed, 2017)Background: The aim of this study was to construct a non-invasive model for acute right ventricular afterload increase by hypoxic pulmonary vasoconstriction. Intact animal models are vital to improving our understanding ... -
A Preoperative Multimarker Approach to Evaluate Acute Kidney Injury After Cardiac Surgery.
(Journal article; Peer reviewed, 2016)Objective To investigate whether a multimarker strategy combining preoperative biomarkers representing distinct pathophysiologic pathways enhances preoperative risk assessment of acute kidney injury after cardiac surgery ... -
A Prospective Population Study of Resting Heart Rate and Peak Oxygen Uptake (the HUNT Study, Norway)
(Journal article; Peer reviewed, 2012)Objectives: We assessed the prospective association of resting heart rate (RHR) at baseline with peak oxygen uptake (VO2peak) 23 years later, and evaluated whether physical activity (PA) could modify this association. ... -
A prospective three-year follow-up study on the clinical significance of anti-neuronal antibodies in acute psychiatric disorders
(Peer reviewed; Journal article, 2019)The clinical significance of anti-neuronal antibodies for psychiatric disorders is controversial. We investigated if a positive anti-neuronal antibody status at admission to acute psychiatric inpatient care was associated ... -
A randomised controlled study of the long-term effects of exercise training on mortality in elderly people: Study protocol for the generation 100 study
(Journal article; Peer reviewed, 2015)Introduction: Epidemiological studies suggest that exercise has a tremendous preventative effect on morbidity and premature death, but these findings need to be confirmed by randomised trials. Generation 100 is a randomised, ... -
A single simulated heliox dive modifies endothelial function in the vascular wall of ApoE knockout male rats more than females
(Journal article; Peer reviewed, 2019)Introduction: The number of divers is rising every year, including an increasing number of aging persons with impaired endothelial function and concomitant atherosclerosis. While diving is an independent modulator of ... -
A Single-Arm, Multicenter Validation Study of Prostate Cancer Localization and Aggressiveness With a Quantitative Multiparametric Magnetic Resonance Imaging Approach.
(Journal article; Peer reviewed, 2019)Objectives: The aims of this study were to assess the discriminative performance of quantitative multiparametric magnetic resonance imaging (mpMRI) between prostate cancer and noncancer tissues and between tumor grade ... -
A small molecule activator of AKT does not reduce ischemic injury of the rat heart
(Journal article; Peer reviewed, 2015)Background Activation of protein kinase AKT is required for cardioprotection by ischemic preconditioning, and transgenic overexpression of AKT protects the heart against ischemia. However, it is unknown whether acute ... -
Abdominal aerobic endurance exercise reveals spot reduction exists : a randomized controlled trial
(Peer reviewed; Journal article, 2023)The existence of spot reduction, exercise-induced local body fat reduction, has been debated for half a century. Although the evidence is equivocal, no study has applied aerobic endurance training closely matching interventions ... -
Absent exercise-induced improvements in fat oxidation in women with polycystic ovary syndrome after high-intensity interval training
(Peer reviewed; Journal article, 2021)Background: Polycystic ovary syndrome (PCOS) and metabolic inflexibility are linked to insulin resistance, and women with PCOS appear to be metabolic inflexible in the rested, insulin-stimulated state. Exercise training ... -
Absolute and relative accelerometer thresholds for determining the association between physical activity and metabolic syndrome in the older adults: The Generation-100 study
(Journal article; Peer reviewed, 2017)Background When assessing population adherence to physical activity (PA) recommendation using accelerometers, absolute intensity threshold definition is applied despite having limited validity in those with low cardiorespiratory ... -
Accuracy of breast cancer lesion classification using intravoxel incoherent motion diffusion-weighted imaging is improved by the inclusion of global or local prior knowledge with bayesian methods
(Journal article; Peer reviewed, 2019)Background Diffusion‐weighted MRI (DWI) has potential to noninvasively characterize breast cancer lesions; models such as intravoxel incoherent motion (IVIM) provide pseudodiffusion parameters that reflect tissue perfusion, ... -
Accuracy of electromagnetic tracking with a prototype field generator in an interventional OR setting
(Journal article; Peer reviewed, 2012)Purpose: The authors have studied the accuracy and robustness of a prototype electromagnetic window field generator (WFG) in an interventional radiology suite with a robotic C-arm. The overall purpose is the development ... -
Accuracy of heart rate watches: Implications for weight management
(Peer reviewed; Journal article, 2016)Background Wrist-worn monitors claim to provide accurate measures of heart rate and energy expenditure. People wishing to lose weight use these devices to monitor energy balance, however the accuracy of these devices ... -
Accuracy of Longitudinal Assessment of Visceral Adipose Tissue by Dual-Energy X-Ray Absorptiometry in Children with Obesity
(Peer reviewed; Journal article, 2019)Background. Increased visceral adipose tissue (VAT) is strongly associated with cardiometabolic risk factors. Accurate quantification of VAT is available through magnetic resonance imaging (MRI), which incurs a significant ... -
Acute and potentially persistent effects of scuba diving on the blood transcriptome of experienced divers
(Journal article; Peer reviewed, 2013)During scuba diving, the circulatory system is stressed by an elevated partial pressure of oxygen while the diver is submerged and by decompression-induced gas bubbles on ascent to the surface. This diving-induced stress ... -
Acute Diffusion Tensor and Kurtosis Imaging and Outcome following Mild Traumatic Brain Injury
