A UPLC-MS/MS coupled with GC-MS method was developed to quantify twenty-one chemical ingredients in multiple tissues from rat after administration of SJP. Protein precipitation and liquid-liquid microextraction were both utilized in sample pretreatment.

The established method was successfully applied in the tissue distribution study of SJP in rats. As a result, the distribution characteristics of ten analytes were clearly elucidated, including borneol, isoborneol, ligustilide, senkyunolide A, ferulic acid, senkyunolide I, levistolide A, neocnidilide, senkyunolide H and angelicide.

Bibliometrics was used to search literature related to “depression” and “SNP” in Web of Science. The obtained SNP information was screened using the PharmGKB database. By designing and optimizing primers and conducting a compound amplification system, a method was established based on MALDI-TOF MS to detect polymorphisms associated with the antidepressant drugs, including sertraline, fluoxetine, citalopram, escitalopram, venlafaxine, fluvoxamine, paroxetine, and mirtazapine.

In humans, these compounds are detected in blood and urine, with significantly higher levels in blood. Their potential as biomarkers of anemia and other diseases is currently being investigated, as their levels change according to the biochemical processes associated with the disease. The most widely used biomarker of anemia is serum ferritin, but it is unreliable in patients with inflammatory bowel disease (IBD) because its levels can be altered by acute inflammation and/or infections. There is therefore a need to look for new markers to help diagnose anemia in IBD patients. This work develops and validates a method for the determination of three protoporphyrins in human urine: protoporphyrin IX (PPIX), protoporphyrin IX complex with Zn (ZnPPIX) and protoporphyrin IX complex with Fe (II) (FePPIX), the latter also known as heme. The aim is to evaluate their potential as biomarkers of anemic disease in patients diagnosed with IBD. The proposed analytical method is based on high performance liquid chromatography (HPLC) with dual detection based on photodiode array (PDA) and fluorescence (FD). Quantification of the analytes at very low concentrations is possible due to the efficient preconcentration provided by dispersive liquid-liquid microextraction (DLLME) and the sensitivity of the detection systems. The method was validated by evaluating linearity (25–1000 ng mL⁻¹), matrix effect, sensitivity (limits of quantification were between 5 and 11 ng mL⁻¹), selectivity, accuracy, carry-over, dilution integrity, stability and precision (&lt; 12.1 %).

Developing topical medications with acetazolamide requires robust analytical methods for its detection in biological samples. In this context, this study aimed to develop a method to quantify acetazolamide in rabbit vitreous humor samples. The method involved a simple, fast, inexpensive, and environmentally friendly protein precipitation step for sample preparation, needing just 50 μL of sample and 200 μL of organic solvent, with adequate recovery. This was combined with high-performance liquid chromatography coupled to tandem mass spectrometry, enabling highly sensitive (LOQ of 5 ng/mL) quantification within only 5 min.

This validated assay was implemented in a proof-of-concept study to compare three low volume sampling devices (Mitra, Tasso-M20 and TassoOne Plus) with serum collected via venipuncture from healthy volunteers receiving etrolizumab. We observed significantly higher concentration of sMAdCAM-1 in dried blood samples collected using Mitra and Tasso-M20 compared to serum in some paired samples, which was attributed to interference from the dried blood extraction buffer. To mitigate this interference, samples required substantial dilution into the appropriate buffer, which negatively impacted the detectability of sMAdCAM-1 with the Gyrolab assay. By employing the Quanterix single molecule array (Simoa), known for its superior assay sensitivity, the interference was minimized in the diluted samples. Both liquid blood collected in TassoOne Plus and dried blood collected using Mitra and Tasso-M20 demonstrated great concordance with serum for sMAdCAM-1 measurement. However, a bias was observed in Mitra dried blood samples, presumably due to the different sample collection sites in comparison with venipuncture and Tasso devices.
