The objective of this study was to evaluate alterations in serum metabolites of transition dairy cows affected by biotin (BIO) and nicotinamide (NAM) supplementation. A total of 40 multiparous Holsteins were paired and assigned randomly within a block to one of the following four treatments: control (T0), 30 mg/day BIO (TB), 45 g/day NAM (TN), and ...
Volumetric absorptive microsampling (VAMS) enables the collection of small and accurate quantities of biological fluids. Therefore, this sampling technique is of great interest for volume-limited samples or serial collection of samples. Here, we present and discuss the potential of VAMS for targeted mass spectrometry (MS)-based metabolomics. In tot...

Rutaecarpine (RUT), evodiamine (EOD) and dehydroevodiamine (DHED), are the three main bioactive indoloquinazoline alkaloids isolated from Euodia ruticarpa, a widely prescribed traditional Chinese medicine. Here, the structure-activity relationships of these analogues for aryl hydrocarbon receptor (AHR) activation were explored by use of Ahr-deficie...

A heteropolysaccharide, named L2, from Lentinula edodes has been proved to possess immunostimulating and anti-ageing activities in previous studies, but its acting mechanism was not completely understood. In this study, 1H NMR spectroscopy approach was employed to investigate the metabolic profiles of the urine from adult mice after L2 intervention...

Bacteria respond to stressful growth conditions through a conserved phenomenon of stringent response mediated by synthesis of stress alarmones ppGpp and pppGpp [referred to as (p)ppGpp]. (p)ppGpp synthesis is known to occur by ribosome-associated RelA. In addition, a dual-function protein, SpoT (with both synthetase and hydrolase activities), maint...

Results demonstrated that metabolomics may be useful for elucidating biological mechanisms associated with the development and severity of PN symptoms, specifically pain and fatigue, in women with early-stage breast cancer.
Diabetes mellitus currently affects over 422 million people globally and over 80% of patients with diabetes will develop diabetic retinopathy. Patients with diabetic retinopathy initially develop background retinopathy, which does not cause significant deterioration of visual function; however, background retinopathy may progress and lead to prolif...
