Direct assay of serum folate by mixing serum with a mixture of L. casei and medium without autoclaving was found to provide serum folate results similar to those by extraction of serum with heat. This procedure was found more reliable than that using the same technique with chloramphenicol and a strain of L. casei adapted to grow in this material. A portion of apparent folate activity assayed i...

We describe the approach to event extraction which the JULIELab Team from FSU Jena (Germany) pursued to solve Task 1 in the “BioNLP’09 Shared Task on Event Extraction”. We incorporate manually curated dictionaries and machine learning methodologies to sort out associated event triggers and arguments on trimmed dependency graph structures. Trimming combines pruning irrelevant lexical material fr...

Measurement precision is often required in the process of material parameter extraction. This fact is applicable to terahertz time-domain spectroscopy (THz-TDS), which is able to determine the optical/dielectric constants of material in the T-ray regime. Essentially, an ultrafast-pulsed THz-TDS system is composed of several mechanical, optical, and electronic parts, each of which is limited in ...

A simple and effective extraction method based on matrix solid-phase dispersion (MSPD) was developed to determine thirteen pyrethroid insecticide residues in goat tissues (liver, kidney, muscle and heart) and milk using gas chromatography electron ionization mass spectrometry method (GC-MS). The samples were pre-concentrated using C18 packing material (dispersion adsorbent), followed by clean u...
