Detection of DNA Methylation in Genomic DNA by UHPLC-MS/MS
, 2020 DNA methylation serves to mark DNA as either a directed epigenetic signaling modification or in response to DNA lesions. Methods for detecting DNA methylation have become increasingly more specific and sensitive over time. Conventional methods for detecting DNA methylation, ranging from paper chromatography to differential restriction enzyme digestion ...

Development of Meps-UHPLC–MS/MS Multistatin Methods for Clinical Analysis
Bioanalysis, 2016 Statins are the microsomal 3-hydroxy-3methylglutaryl-coenzyme A reductase inhibitors used for the treatment of hypercholesterolemia. Some recent studies revealed also the extra-lipid effects and anticancer activities. Due to the wide incidence of cancer diseases, the number of studies dealing with anticancer statin activities has grown in recent years.

UHPLC–MS/MS based target profiling of stress-induced phytohormones
Phytochemistry, 2014 Stress-induced changes in phytohormone metabolite profiles have rapid effects on plant metabolic activity and growth. The jasmonates (JAs) are a group of fatty acid-derived stress response regulators with roles in numerous developmental processes. To elucidate their dual regulatory effects, which overlap with those of other important defence-signalling

Determination of imidacloprid in beehive samples by UHPLC-MS/MS
Microchemical Journal, 2018 Abstract Imidacloprid is a systemic insecticide belonging to the neonicotinoid family. It was the first neonicotinoid introduced in the mid-1990s, and since then, its use has grown rapidly to control pests in a variety of agricultural crops. Several studies have shown that neonicotinoids translocate to the nectar and pollen of treated plants, which ...

UHPLC-MS/MS-based untargeted lipidomics analysis of septic patients
Clinica Chimica Acta, 2023 Lipids take part in many pathophysiological processes of sepsis, thus, the variation of lipid composition may have clue on the severity and pathogen to sepsis. The objective of our study is to expand the profile of lipid compositions and screen potential biomarkers in intensive care unit (ICU) patients with sepsis.Patients admitted to the ICU clearly ...
