Objective:

To summarize recent advancements and findings in mass spectrometry and related fields.

Approach:

• MEATiCode Introduction: A comprehensive proteomic LC-MSMS method for meat authentication.
• DMSP Lyase Activity Analysis: Development of a simplified method using a gas dissolved gas extraction device with SIFT-MS.
• Novel Biomarker Discovery: UPLC-MS/MS identifies 2-phenoxyethanol as a biomarker for active periodontal disease.
• Minocycline Hydrochloride Analysis: Separation and identification of substances in minocycline tablets using 2D-LC-Q-TOF/MS.
• Metabolic Shifts in Glaucoma: UPLC-MS/MS measures tryptophan and related compounds in eye fluid of glaucoma patients.
• Glucose as a Regulator: Research from Stanford Medicine shows glucose regulates tissue differentiation by binding to proteins.
