Automated quantification of myocardial perfusion SPECT using simplified normal limits
Journal of Nuclear Cardiology, 2005To simplify development of normal limits for myocardial perfusion SPECT (MPS), we implemented a quantification scheme in which normal limits are derived without visual scoring of abnormal scans or optimization of regional thresholds.Normal limits were derived from same-day TI-201 rest/Tc-99m-sestamibi stress scans of male (n = 40) and female (n = 40 ...

Quantification of Early Subclinical Limited Joint Mobility in Diabetes Mellitus
Diabetes Care, 1985Limited joint mobility (LJM) has been described in juvenile diabetic patients by Rosenbloom et al.; similar abnormalities are also present in adult diabetes. This modification may be associated with a high risk of microvascular complications. We tested the use of a goniometer in measuring subclinical joint limitation in 50 adult diabetic patients ...

Evaluation of Approximate Methods for Calculating the Limit of Detection and Limit of Quantification
Environmental Science & Technology, 1999In a previous paper, a computational method was presented for determining statistically rigorous limits of detection and quantification. The main purpose of this study is to evaluate similar but less computationally complex methods. These approximate methods use data at multiple spiking concentrations, are iterative, can be derived from either ...

Limitations of diazomethane for the quantification of 15-Oxo-prostaglandin F2α
Biological Mass Spectrometry, 1977The relatively rapid formation of pyrazoline adducts is a serious side reaction in the esterification of 15-oxo-PGF2alpha with ethereal diazomethane under conditions used routinely in the chemical derivatization of prostaglandins.

Quantification of airflow limitation in chronic obstructive pulmonary disease
Respiratory function technologists/scient, 2018Background: Airflow limitation is a mechanical pathophysiological condition occurring, either during physical exercise or at rest. Objective: Accurate measurement of airflow limitation in COPD patients and correlation between standard FEV1 (as an evidence for diagnosis and grading of airway obstruction) and Ventilatory Flow Limitation (VFL) as an ...

Does regulation kill jobs?: The limits of quantification
Regulation & Governance, 2015AbstractThis essay reviews a new edited volume entitled Does Regulation Kill Jobs? It concludes that this book brings much needed data and realism to the debate about jobs and the environment, showing that government regulation generally has minor impacts on employment. This essay focuses much of its attention on the suggestion, discussed by several of

Narrative and the Fundamental Limitations of Quantification in Crosscultural Research
Medical Care, 2006at least the last 3 decades, international and crosscultural studies of health, religious beliefs, political attitudes, and much else of a fundamentally subjective nature have proliferated. Interest in comparative research emerges from the desire to understand how different cultural, economic, political, and social systems influence individuals' world ...

Hyperpolarized Nano-NMR Platform for Quantification of Mass Limited Samples
Analytical ChemistryMetabolic flux analysis of live cells using NMR enables the study of cancer metabolism and response to treatment. However, conventional NMR platforms require often prohibitively high numbers of cells to achieve significant resolution. In this work, we present a double 1H/13C resonance NMR probe consisting of a solenoid coil with a less than 100 nL ...
