Article Abstract
Blood plasma is one of the most commonly analyzed and easily accessible biological samples. Here, we describe an automated liquid-liquid extraction platform that generates accurate, precise, and reproducible samples for metabolomic, lipidomic, and proteomic analyses from a single aliquot of plasma while minimizing hands-on time and avoiding contamination from plasticware. We applied mass spectrometry to examine the metabolome, lipidome, and proteome of 90 plasma samples to determine the effects of age, time of day, and a high-fat diet in mice. From 25 μl of mouse plasma, we identified 907 lipid species from 16 different lipid classes and subclasses, 233 polar metabolites, and 344 proteins. We found that the high-fat diet induced only mild changes in the polar metabolome, upregulated apolipoproteins, and induced substantial shifts in the lipidome, including a significant increase in arachidonic acid and a decrease in eicosapentaenoic acid content across all lipid classes.
We recently reported factors leading to different severity of ruminal pH drop in primiparous cows fed the same diet during transition and early lactation. The present study evaluates the effects of those severities on performance and several blood and balance parameters in the same 24 primiparous cows from 3 wk before calving until wk 10 in lactation. Dietary concentrate was increased for all cows from 32 before calving to 60% (DM basis) over the first wk in lactation, resulting in a diet with 40% non-fiber carbohydrates (NFC), and 14.
Background And Objectives: Maternal western-style diets that are high in glucose and fat have well-known cardiovascular effects on offspring, yet the combined influence of such diets during pregnancy is relatively less comprehended. This study investigates the impact of maternal high glucose and fat diet (HGF) on vascular constriction in offspring and the underlying mechanisms.
Methods And Results: Pregnant Sprague-Dawley rats were provided with either HGF or control diets.
Objective: To analyze the fatty acid content of Jiangnan dishes in Hangzhou.
Methods: Based on the order frequency records from an online platform, two popular Jiangnan cuisine restaurants were selected for monitoring. Fat extraction was performed on three types of dishes: purely vegetarian, mixed vegetarian and non-vegetarian, and purely non-vegetarian, using acid hydrolysis.

Aims: Semaglutide, a novel long-acting GLP-1RA, stimulates insulin and suppresses islet-secreted glucagon to reduce glucose levels. It has been unveiled that m6A mRNA modification plays a pivotal role in regulating β cell function. However, it remains unclear whether semaglutide can elicit protective effects through manipulating m6A modification and the underlying mechanism.
Alcohol-associated liver disease (ALD), primarily caused by chronic excessive alcohol consumption, is a leading cause of chronic liver disease worldwide. ALD includes alcohol-associated steatotic liver, alcohol-associated hepatitis (AH), fibrosis, cirrhosis, and can even progress to hepatocellular carcinoma (HCC). Existing research indicates that the risk factors of ALD are quite numerous.
