Fluorometric high-performance liquid chromatography of N-acetyl- and N-glycolylneuraminic acids and its application to their microdetermination in human and animal sera, glycoproteins, and glycolipids.

S Hara et al.

Analytical biochemistry, 164(1), 138-145 (1987-07-01)

A simple, rapid, and highly sensitive high-performance liquid chromatographic method is described for the determination of N-acetyl- and N-glycolylneuraminic acids in human and animal sera, glycoproteins, and glycolipids. The neuraminic acids, released by acid hydrolysis of these biological samples, are

An efficient assay for identification and quantitative evaluation of potential polysialyltransferase inhibitors.

Xiaoxiao Guo et al.

The Analyst, 145(13), 4512-4521 (2020-05-16)

The polysialyltransferases (polySTs) catalyse the polymerisation of polysialic acid, which plays an important role in tumour metastasis. While assays are available to assess polyST enzyme activity, there is no methodology available specifically optimised for identification and quantitative evaluation of potential

Studies of the humoral factors produced by layered chondrocyte sheets.

K Hamahashi et al.

Journal of tissue engineering and regenerative medicine, 9(1), 24-30 (2012-11-21)

The authors aimed to repair and regenerate articular cartilage with layered chondrocyte sheets, produced using temperature-responsive culture dishes. The purpose of this study was to investigate the humoral factors produced by layered chondrocyte sheets. Articular chondrocytes and synovial cells were

Left hippocampus-amygdala complex macro- and microstructural variation is associated with BDNF plasma levels in healthy elderly individuals.

Antonietta Manna et al.

Brain and behavior, 5(7), e00334-e00334 (2015-07-30)

Deep brain gray matter (GM) structures are involved in several neurodegenerative disorders and are affected by aging. In this study, we investigated the potential relationship between levels of brain-derived neurotrophic factor (BDNF), a putative biomarker of age- and clinically relevant
