Dual parallel mass spectrometry for lipid and vitamin D analysis.
There are numerous options for mass spectrometric analysis of lipids, including different types of ionization, and a wide variety of experiments using different scan modes that can be conducted. Atmospheric pressure chemical ionization (APCI) and electrospray ionization (ESI) provide complementary types of information that are both desirable. However, the duty cycle of the mass spectrometer pla...
متن کاملSensitometric characteristics of D-, E- and F-speed dental radiographic films in manual and automatic processing
BACKGROUND: The purpose of this study was to evaluate the sensitometric characteristics of Ultraspeed, Ektaspeed Plus and Insight dental radiographic films using manual and automatic processing systems. METHODS: In this experimental invitro study, an aluminum step-wedge was used to construct characteristic curves for D-, E- and F-speed radiographic films (Kodak Eastman, Rochester, USA). All fil...
متن کاملTesting vitamin D levels.
Evidence • A systematic review1 on 25-hydroxyvitamin D (25[OH] D) suggests levels greater than 75 nmol/L “are not consistently associated with increased benefit”; greater than 50 nmol/L are “practically sufficient for all persons”; between 30 and 50 nmol/L “places some, but not all, persons at risk for inadequacy”; and less than 30 nmol/L puts one “at risk relative to bone health.” • No RCTs in...
متن کاملOptimizing specimen collection for processing in clinical testing laboratories
We study the logistics of specimen collection for a clinical testing laboratory that serves sites dispersed in an urban area. The specimens that accumulate at the customer sites throughout the working day are transported to the laboratory for processing. The problem is to construct and schedule a series of tours to collect the accumulated specimens from the sites throughout the day. Two hierarc...
متن کاملComparing manual and automated extraction of chemical entities from documents
The chemical information landscape is changing rapidly with a yearly increase of over 1 million new compounds and more than 700,000 publications related to chemistry [1]. Exploring the chemical space covered by relevant journals and patents is a crucial step in early stage medicinal chemistry projects. Extracting chemical entities from unstructured text is a complex task and different approache...
