Novel Gpr39 Agonists: Correlation Of Binding Affinity Using Label-Free Back-Scattering Interferometry With Potency In Functional Assays
We describe the application of back-scattering interferometry (BSI) to the characterization of small molecule ligand binding to human GPR39 (a GPCR targeted for type-2 diabetes therapy) overexpressed in crude membrane fractions in free solution, including how BSI-derived affinity and functional assay-derived potency correlate for compounds of varying scaffolds

Simultaneous multi-determination and transfer of eight pesticide residues from green tea leaves to infusion using gas chromatography
Acetonitrile was used as the extraction solvent with sodium chloride to enhance the partitioning of analytes into the organic phase. Recovery indicated good method accuracy and repeatability, and was within the acceptable range for residue determinations. The mere presence of pesticide residues in tea does not necessarily mean that the tea has become toxic and would pose a health hazard. We revealed that only a negligible or small percentage of pesticides in tea is transferred to the infusion.

Analysis of 10 systemic pesticide residues in various baby foods using liquid chromatography-tandem mass spectrometry
The method developed was sensitive and selective, and detected the analytes below the MRL established by the European Commission and the Korea Food and Drug Administration. The combination of QuEChERS sample preparation and LC-MS/MS analysis provided acceptable quantitative and qualitative results in baby food.

Correlation between plasma levels of lutein and oxidized low density lipoproteins: a short human intervention study
The increase of plasma carotenoids, in particular lutein, after dietary treatment for two weeks is associated with a significant protective effect against lipid peroxidation of plasma lipoproteins.

2nd round audit of skeletal surveys in patients with Monoclonal Gammopathy of Undetermined Significance (MGUS)
Action plan post 1st round audit has been successfully implemented. 100% requests for Urine Bence Jones protein and serum kappa/lambda ratio (previously 79 out of 88 (90%) and 33 out of 88 (38%) respectively requested). Only 1 out of 24 patients had an inappropriate referral for skeletal surveys with MGUS.

DETERMINATION OF HOMOCYSTEINE THIOLACTONE IN URINE BY FIELD AMPLIFIED SAMPLE INJECTION AND SWEEPING MEKC METHOD WITH UV DETECTION
* The procedure does not overload the capillary and has positive effect on the increase in peak hight,
* The method allows about 70-fold increase in method sensitivity,
* The limits of detection and quantification are 0.1 nmol and 0.09 nmol of Hcy-thiolactone in 1 mL of urine, respectively,
* Presented assay can be used for the determination of Hcy-thiolactone in biological samples.

GC-MS/MS Analysis of Pesticide Residue in Green Tea Extracted by QuEChERS with Acetonitrile as Final Solvent
QuEChERS involves an initial step when a few grams of the sample are extracted with acetonitrile followed by a clean-up step (with dispersive-SPE) used to remove, to a certain extent, unwanted matrix compound (such as pigments, sugars, organic acids). With QuEChERS, the final extract ends up with the pesticides in acetonitrile, which, being polar solvent, can be
