The poster describes similarities and differences of the effects aquaculture effluents have on the nitrogen composition in estuarine waters of two sites in southern China

We characterised iPS cell-derived human neural progenitor cells (hNPCs) and their progeny produced using optimised methods to examine their suitability for neurobiology research.

MAB Discovery GmbH developped a highly integrated process which provides diverse antibodies by starting with a high number of B cells and filtering the relevant antibodies by an early-on functional screening.

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

A sharp, narrow, and sensitive peak is a pre-condition for a sensitive GC analysis. Therefore, a protectant is needed to protect the analyte from any type of distortion for integration and to prevent overestimation. Existing solutions do not overcome these problems completely due to limitations. As the matrix enhancement problem originated from matrix components, its solution should come from similar components.

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.

The dSPE of QuEChERS was replaced with an SPE cartridge, which provided a very clean chromatogram, although a small recovery percentage was obtained. The method fulfilled all validation criteria and was useful for monitoring etoxazole residues in red pepper. It can also be used and optimized for other fruit and vegetable matrices.

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.

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.

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.
