Purpose To determine the relationship between pulmonary artery (PA) stiffness and both right ventricular (RV) mass and function with cardiac magnetic resonance (MR) imaging. Materials and Methods The study was approved by the local research ethics committee, and all participants gave written informed consent. Cardiac MR imaging was performed at 1.5 T in 156(More)
This paper describes a practical procedure to establish a sensitive radioimmunoassay for the measurement of human thyroglobulin (HTg) in serum. The assay enables a clear distinction to be made between levels of HTg indicating the presence or absence of functioning thyroid tissue. It compares the use of HTg serum levels with the conventional I-131 scintigram(More)
Background Exercise CMR is an emerging technique for understanding the effects of physiological stress on the cardiovascular system in health and disease. Accurate assessment of cardiovascular performance during exercise is challenging due to high heart rates and respiratory motion therefore new imaging tools are required for real-time measurement of(More)
Background Hypoxia induces pulmonary vasoconstriction leading to an increase in pulmonary vascular resistance and acute pulmonary hypertension (PH). It is known that with acute hypoxia, cardiac output (CO) is maintained with an increase in heart rate (HR) but a blunted stroke volume (SV) response. To our knowledge, the response of the healthy heart to acute(More)
The production of an agricultural commodity involves a sequence of processes: planting/growing, harvesting, sorting/grading, postharvest treatment, packing, and exporting. A Bayesian network has been developed to represent the level of potential infestation of an agricultural commodity by a specified pest along an agricultural production chain. It reflects(More)
