A yeast model of 5‐oxoproline accumulation reveals a general toleration to 5‐oxoproline
FEBS Open Bio, EarlyView.Using a yeast model, we show that even high accumulation of 5‐oxoproline causes only mild cellular stress and does not trigger oxidative stress. Instead, cells adapt by activating efflux pumps and diverse protective pathways, suggesting that previously proposed harmful effects of 5‐oxoproline may arise from indirect metabolic imbalances rather than the

Aromatic Monomer Analysis by UHPLC-MS/MS v1
, 2023 An analysis method was developed to allow for quantitation of aromatic compounds by ultra high pressure liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) detection. This was achieved by using reverse phase chromatography and multiple reaction monitoring (MRM) in negative ion mode using electrospray ionization (ESI).

FEBS Open Bio, EarlyView.Time‐restricted feeding (TRF) in mice increased liver fatty acid oxidation and decreased fatty acid biosynthesis. These alterations persisted when TRF was discontinued and the host was infected with Mycobacterium tuberculosis. Pre‐exposure to TRF did not alter tissue (lung and spleen) mycobacterial burden but significantly reduced CD3+ T cells in lungs

Analysis of Vitamin D Components in Serum of Minors by UHPLC-MS/MS
Journal of Nutritional Science and Vitaminology, 2021 Serum 25-hydroxyvitamin D [25(OH)D] concentration represents the body's reserves of vitamin D, which is mostly used by clinicians to evaluate the storage status of vitamin D in the body. The present study aimed to investigate the serum vitamin D components in different health status of minors to correctly evaluate the vitamin D storage in vivo. A total
