Standardized, innovative terms, including those for reproductive and endocrine effects, enrich the developed ontology. The database is intended to support analyses of correlation and concordance through the connection between the levels of observed and non-observed effects. Importantly, it supplies a substantial collection of drug information for the pharmaceutical sector and scientific research. Reported analyses of toxicological information are supported by the ontology, especially for endpoints related to reproduction and endocrine systems. It can also be used to encode existing data or to create new ontologies. The potential of the new database and ontology extends to the support of alternative non-animal approaches, the exploration of toxicity mechanisms, and the evaluation of human relevance. A free IUCLID database is accessible at https//iuclid6.echa.europa.eu/us-fda-toxicity-data, offering a wealth of information. Excess free fatty acids, specifically saturated fatty acids like palmitic acid, lead to lipotoxicity, a crucial component of the pathogenesis in nonalcoholic fatty liver disease (NAFLD). The toxicity of saturated fatty acids (SFAs) can be countered by unsaturated fatty acids (UFAs), such as oleic acid (OA), which are nontoxic and can reduce cell apoptosis, diminish endoplasmic reticulum stress (ER stress), and improve lipid metabolism. Although, whether OA is capable of regulating autophagy is largely undetermined. Our study examines the mechanisms by which OA-mediated modulation of autophagy occurs in hepatocytes and NAFLD mice. Within a 48-hour period in vitro, palmitic acid (PA)/tunicamycin (TM) or/and oleic acid (OA) were applied to human hepatoma HepG2 cells, normal human liver L-02 cells, and normal mouse liver AML12 cells. Through in vivo feeding of a high-fat diet (HFD), C57/BL6 mice developed NAFLD. A partial replacement of the HFD with olive oil was carried out to observe the potential protective effects of olive oil. Treatment with PA/TM exhibited a negative impact on cell viability and elicited a cellular apoptotic response in both HepG2 and L-02 cell cultures. The influence of PA/TM on autophagy is negatively correlated with the decrease in TFEB nuclear translocation and the suppression of CTSB enzyme activity. However, OA demonstrably ameliorated the PA/TM-induced apoptosis and autophagy deficits within hepatocytes. In parallel with this, the re-establishment of autophagy activity proves capable of diminishing endoplasmic reticulum stress. Furthermore, a 20-week HFD regime effectively created NAFLD in C57/BL6 mice, and the consequential result was a substantial decline in liver autophagy. Remarkably, a 30% swap of HFD for olive oil led to a profound reversal of NAFLD. Significant enhancement of steatosis improvement was observed, along with a reduction in liver tissue autophagy dysfunction, ER stress, and apoptosis. The data unequivocally demonstrate that OA can effectively ameliorate autophagy dysfunction caused by both PA and ER stress-induced lipotoxicity. OA's impact on lysosomal dysfunction through TFEB is prominent, suggesting that manipulation of the ER stress-autophagy pathway is essential in OA's protective mechanism in NAFLD. Metabolic syndrome (MetS) is strongly associated with altered endocrine-metabolic and cardiac functions, making individuals more susceptible to cardiovascular disease, dyslipidemia, and type-2 diabetes mellitus. L-Arginine's dietary inclusion promotes fat loss, conversely, chronic aerobic exercise proves effective in mitigating the cardiovascular, autonomic, and metabolic complications of obesity. Despite this, the correlation between these two techniques has not been elucidated. This study examined the potential benefits of physical training, with or without l-arginine supplementation, on cardiovascular, autonomic, and metabolic parameters in rats with Metabolic Syndrome (MetS), which was developed by subcutaneous administration of monosod
