Limitations of diazomethane for the quantification of 15-Oxo-prostaglandin F2α

Biological Mass Spectrometry, 1977
The 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, 2018
Background: 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 ...

Narrative and the Fundamental Limitations of Quantification in Crosscultural Research

Medical Care, 2006
at 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 Chemistry
Metabolic 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 ...
