KRAS G12C-mutant non-small-cell lung cancer: biology, developmental therapeutics, and molecular testing

KRAS mutation is the most typical oncogenic driver in superior non-small cell lung most cancers (NSCLC), occurring in roughly 30% of lung adenocarcinomas. Over 80% of oncogenic KRAS mutations happen at codon 12 the place the glycine residue is substituted by completely different amino acids, resulting in genomic heterogeneity of KRAS-mutant tumors. The KRAS glycine-to-cysteine…

Spinochrome Identification and Quantification in Pacific Sea Urchin Shells, Coelomic Fluid and Eggs Using HPLC-DAD-MS

Spinochrome Identification and Quantification in Pacific Sea Urchin Shells, Coelomic Fluid and Eggs Using HPLC-DAD-MS

The high-performance liquid chromatography technique coupled with diode array and mass spectrometric detector (HPLC-DAD-MS) technique for quinonoid pigment identification and quantification in sea urchin samples was developed and validated. The composition and quantitative ratio of the quinonoid pigments of the shells of 16 species of sea urchins, collected within the temperate (Sea of Japan) and…
