Article Abstract
This study aimed to investigate the changes in intestinal homeostasis and metabolism in mice after methamphetamine (MA) administration and exercise intervention. In this study, male C57BL/B6J mice were selected to establish a model of methamphetamine-induced addiction, and the gut microbiota composition, short-chain fatty acids (SCFAs), and amino acid levels were assessed by 16S rRNA, liquid chromatography-tandem mass spectrometry, and gas chromatography-tandem mass spectrometry, respectively. The results showed that 23 dominant microbiota, 12 amino acids, and 1 SCFA were remarkably higher and 9 amino acids and 6 SCFAs were remarkably lower in the exercise model group than in the control group. Among the top 10 markers with opposite trends between the exercise intervention group and model group, the differential microbiomes included , , , , , , and ; amino acids included proline; and SCFAs included isovaleric acid and pentanoic acid. Proline was negatively correlated with and positively correlated with pentanoic acid. The results suggested that moderate-intensity aerobic exercise may modulate changes in the composition of the gut microbiota and the levels of amino acids and SCFAs induced by MA administration.

Neuronal development and function are orchestrated by a plethora of regulatory mechanisms that control the abundance, localization, interactions, and function of proteins. A key role in this regard is assumed by post-translational protein modifications (PTMs). While some PTM types, such as phosphorylation or ubiquitination, have been explored comprehensively, PTMs involving ubiquitin-like modifiers (Ubls) have remained comparably enigmatic (Ubls).

Elevated expense of chemical media spurs a shift to non-chemical media in microalgal cultivation, while ensuring the safety of the resulting powder poses a challenge. No previous studies have evaluated the safety and application of Spirulina subsalsa powder cultivated in monosodium glutamate wastewater (MSGW) and seawater. In this study, an analysis of basic nutritional components in Spirulina subsalsa powder indicated that this algal powder had high protein content, low lipid content and rich mineral content.

Background: There is considerable variation in the anabolic action of ingesting protein-dense foods on the stimulation of postprandial myofibrillar protein synthesis rates (MPS) despite ingesting similar amounts of protein and essential amino acids (EAA) OBJECTIVES: To determine the effects of consuming high-fat pork (HFP), low-fat pork (LFP), or a carbohydrate control (CHO) on the MPS response METHODS: In a semi-crossover design, sixteen physically active adults (25 ± 5 y; 25.0 ± 2.3 kg·m; 12M, 4F) received primed-constant infusions of L-[ring-C]phenylalanine and performed an acute bout of resistance exercise.
