The mechanisms by which exercise benefits patients with non-alcoholic fatty liver disease (NAFLD), the most common worldwide, remain poorly understood. A non-targeted liquid chromatography-mass spectrometry (LC-MS)-based metabolomics analysis was used to identify metabolic changes associated NAFLD in humans upon intervention (without diet change) across four different sample types-adipose tissue (AT), plasma, urine, and stool. Altogether, 46 subjects participated this randomized controlled...

Abstract The essential role of gut microbiota in health and disease is well recognized, but the biochemical details that underlie beneficial impact remain largely undefined. To maintain its stability, participates an interactive host-microbiota metabolic signaling, impacting phenotypes host. Dysbiosis results alteration certain microbial host metabolites. Identifying these markers could enhance early detection diseases. We report LC–MS based non-targeted profiling demonstrates a large effect...

The current epidemics of cardiovascular and metabolic noncommunicable diseases have emerged alongside dramatic modifications in lifestyle living environments. These correspond to changes our "modern" postwar societies globally characterized by rural-to-urban migration, modernization agricultural practices, transportation, climate change, aging. Evidence suggests that these are related each other, although the social biological mechanisms as well their interactions yet be uncovered....

Long-term lifestyle interventions in childhood and adolescence can significantly improve cardiometabolic health, but the underlying molecular mechanisms remain poorly understood. To address this knowledge gap, we conducted an 8-year diet physical activity intervention a general population of children. The research revealed that influenced 80 serum metabolites over two years, with 17 continuing to be affected after eight years. primarily impacted fatty amides, including palmitic amide,...

Cold-induced brown adipose tissue (BAT) activation is considered to improve metabolic health. In murine BAT, cold increases the fundamental molecule for mitochondrial function, nicotinamide adenine dinucleotide (NAD+), but limited knowledge of NAD+ metabolism during in human BAT exists. We show that serum metabolites salvage pathway (nicotinamide and 1-methylnicotinamide) humans. Additionally, individuals with cold-stimulated have decreased levels from de novo biosynthesis (tryptophan,...

Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as non-alcoholic fatty (NAFLD), is the most prevalent globally, yet no therapies are approved. The effects of Escherichia coli Nissle 1917 expressing aldafermin, an engineered analog intestinal hormone FGF19, in combination with dietary change were investigated a potential treatment for MASLD. MASLD was induced C57BL/6J male mice by American lifestyle-induced obesity syndrome diet and then switched to standard...

We investigated whether changes in the metabolome precede incident diagnoses of alcohol-related diseases.This is a prospective population-based cohort study where participants were 42- to 60-year-old males at baseline (years 1984 1989). Subjects who received diagnosis for an disease during follow-up defined as cases (n = 92, mean 13.6 years before diagnosis). Diagnoses obtained through linkage national health...
