We performed a comprehensive study of protein (total protein, medium-molecular-weight peptides, creatinine, and urea), purine (uric acid), and lipid (cholesterol, triglycerides) metabolism, activity of AST, ALT, and acid phosphatase in blood plasma of white male rats under conditions of restriction of motor activity up to 28 days. Patterns of changes in metabolic profile during hypokinesia were established: prevalence of catabolic processes and atherogenic shifts in the lipid spectrum with maximum manifestation on 14-21 days of the experiment.

Macrophages remove apoptotic cells via phagocytosis, also known as efferocytosis, during inflammation to maintain tissue homeostasis. This process is accompanied by various metabolic changes in macrophages including the production of lipid metabolites by fatty acid oxygenases. Among these, highly reactive metabolites, called lipid-derived electrophiles (LDEs), modify cysteines and other nucleophilic amino acids in intracellular proteins.

Flavonoids are the major medicinally active ingredients that exert potential effects in Amomum tsao-ko. In total, 277 flavonoid metabolites were identified in fresh and dried fruits of three different accessions of A. tsao-ko (Amomum tsao-ko), which could be classified into eight classes with more metabolites classified as flavonol.

This investigation represents a pioneering effort to examine the therapeutic effects of PCB specifically in the context of CFA-induced mice, as well as to elucidate the underlying mechanisms that facilitate such effects. Our study utilized advanced methodologies, namely high-performance liquid chromatography coupled with mass spectrometry (HPLC-MS)-based metabolomics, alongside comprehensive multivariate data analysis, to identify a distinctive metabolic profile associated with acute inflammation. Through our analyses, we discovered that several potential metabolites were significantly implicated in a variety of critical metabolic pathways.

Given the extensive use of plastic materials in modern society, there is an escalating concern about the potential risks associated with exposure to plastic products. This study investigated the impact of plastic leachates from boiled-water-treated cups, including polypropylene (PP), high-density polyethylene (HDPE), low-density polyethylene (LDPE), polystyrene (PS), and polyethylene terephthalate (PET), on male reproductive health. Experimental mice were administered daily doses of the plastic leachates for 180 consecutive days.
