Abstract
OBJECTIVE Orofacial pain with high prevalence is one of the substantial human health issues. The importance of this matter became more apparent when it was revealed that orofacial pain, directly and indirectly, affects cognition performances. Currently, researchers have focused on investigating pharmaceutics to alleviate pain and ameliorate its subsequent cognitive impairments. DESIGN In this study, the rats were first treated with the central administration of methyl jasmonate (MeJA), which is an antioxidant and anti-inflammatory bio-compound. After 20 min, orofacial pain was induced in the rats by the injection of capsaicin in their dental pulp. Subsequently, the animals' pain behaviors were analyzed, and the effects of pain and MeJA treatments on rats learning and memory were evaluated/compared using the Morris water maze (MWM) test. In addition, the expression of tumor necrosis factor-α (TNF-α), IL-1β, BDNF, and COX-2 genes in the rats' hippocampus was evaluated using real-time polymerase chain reaction. RESULTS Experiencing orofacial pain resulted in a significant decline in the rats learning and memory. However, the central administration of 20 μg/rat of MeJA effectively mitigated these impairments. In the MWM, the performance of the MeJA-treated rats showed a two- to threefold improvement compared to the nontreated ones. Moreover, in the hippocampus of pain-induced rats, the expression of pro-inflammatory factors TNF-α, IL-1β, and COX-2 significantly increased, whereas the BDNF expression decreased. In contrast, MeJA downregulated the pro-inflammatory factors and upregulated the BDNF by more than 50%. CONCLUSIONS These findings highlight the notable antinociceptive potential of MeJA and its ability to inhibit pain-induced learning and memory dysfunction through its anti-inflammatory effect.

Abstract
Objectives Active plant ingredients have been successfully used in modern medicine to control appetite and energy hemostasis. This study was designed to evaluate the efficacy of the phytohormone methyl jasmonate (MJ) on food-related behaviors in rats. Materials and Methods Adult male Wistar rats were randomly divided into different groups (7 rats) and infused intracerebroventricularly (i.c.v.) with MJ vehicle (DMSO) or MJ (2.5, 5 and 10 μg/rat). Then, the individual rats were placed in an automated open field-like apparatus to assess a 12-h food-related activity in light and dark times. After behavioral tests, immunofluorescence staining of the orexin 1 receptor (Orx1R) was studied in the hypothalamus of rats. Results MJ (2.5, 5, and 10 μg/rat) administration significantly decreased food intake in the light and dark phases compared with the control group. Moreover, all the MJ-treated groups exhibited a decrease in visits to food containers at the light and dark times (p < 0.001). In addition, rats infused with MJ at 5 μg and 10 μg spent less time in the ports of food containers in the light and dark phases in comparison with control rats. Time in zone-related to food and locomotor activity was significantly decreased in the MJ (5 μg) groups during the light time and in all MJ-injected groups in the dark time. Moreover, hypothalamic expression of Orx1R in rats treated with MJ (5 μg) was significantly lower as compared to the control group. Conclusion Overall, the results indicated the potential of MJ to modulate feeding-related behavior and Orx1R expression in the hypothalamus of rats.

Neuroprotective effects of methyl jasmonate in male Wistar rats exposed to delayed acetic acid-induced ulcerative colitis: involvement of antioxidant status, GFAP, and IBA-1 immunoreactivities. Metab Brain Dis 2023; 38:671-686.

Abstract
Neurobehavioral deficits have been severally reported as a comorbid outcome in inflammatory bowel diseases (IBDs). This study evaluated neurological changes in the experimental model of IBDs, as well potential protective effects of methyl jasmonate (MJ). The study used the acetic acid model of colitis and thereafter delayed the healing process by the administration of indomethacin (Indo) (2 mg/kg, SC). Thirty male Wistar rats (120-160 g) were divided into 5 groups (n = 6). Control, Colitis, Colitis + Indo, MJ (50 mg/kg, IP) + Colitis and MJ + Colitis + Indo. Colitis was induced by intrarectal administration of 2 mL, 4% acetic acid. Neurobehavioral studies were carried out to assess memory function, depression, and anxiety on day 7 of post-colitis induction. Animals were thereafter sacrificed to collect the brain tissues for routine histology, immunoreactivity of GFAP and IBA-1, and biochemical assays. Neurobehavioral tests showed anxiety, depression, and memory deficits, especially in the Colitis + Indo group which were accompanied by increased IBA-1 and GFAP count. MJ reversed these effects and reduced GFAP count in the hippocampus and amygdala as well as IBA-1 count in the hippocampus, amygdala, and cortex. Histological observations of these areas showed no significant histopathological changes across all groups. GPx and CAT levels were significantly reduced, while MPO was significantly increased in colitis and Colitis+indo groups when compared with control, which was attenuated in groups administered with MJ. These findings tuggest that MJ possesses neuroprotective, anti-oxidant, and neuron-regeneration properties. Therefore, it could be considered as a potential treatment for behavioral deficits associated with ulcerative colitis.

Abstract
The purpose of our study was to explore potential characteristic biomarkers in patients with sepsis. Peripheral blood specimens from sepsis patients and normal human volunteers were processed by liquid chromatography-mass spectrometry-based analysis. Outlier data were excluded by principal component analysis and orthogonal partial least squares-discriminant analysis using the metabolomics R software package metaX and MetaboAnalyst 5.0 ( https://www.metaboanalyst.ca/home.xhtml ) online analysis software, and differential metabolite counts were identified by using volcano and heatmaps. The obtained differential metabolites were combined with KEGG (Kyoto Gene and Kyoto Encyclopedia) analysis to screen out potential core differential metabolites, and ROC curves were drawn to analyze the changes in serum metabolites in sepsis patients and to explore the potential value of the metabolites in the diagnosis of sepsis patients. By metabolomic analysis, nine differential metabolites were screened for their significance in guiding the diagnosis and differential diagnosis of sepsis namely: 3-phenyl lactic acid, N-phenylacetylglutamine, phenylethylamine, traumatin, xanthine, methyl jasmonate, indole, l-tryptophan and 1107116. In this study, nine metabolites were finally screened based on metabolomic analysis and used as potential characteristic biomarkers for the diagnosis of sepsis.

Abstract
For immobile plants, the main means of protection against adverse environmental factors is the biosynthesis of various secondary (specialized) metabolites. The extreme diversity and high biological activity of these metabolites determine the researchers' interest in plants as a source of therapeutic agents. Oxylipins, oxygenated derivatives of fatty acids, are particularly promising in this regard. Plant oxylipins, which are characterized by a diversity of chemical structures, can exert protective and therapeutic properties in animal cells. While the therapeutic potential of some classes of plant oxylipins, such as jasmonates and acetylenic oxylipins, has been analyzed thoroughly, other oxylipins are barely studied in this regard. Here, we present a comprehensive overview of the therapeutic potential of all major classes of plant oxylipins, including derivatives of acetylenic fatty acids, jasmonates, six- and nine-carbon aldehydes, oxy-, epoxy-, and hydroxy-derivatives of fatty acids, as well as spontaneously formed phytoprostanes and phytofurans. The presented analysis will provide an impetus for further research investigating the beneficial properties of these secondary metabolites and bringing them closer to practical applications.
