Abstract
Oxidative stress is increasingly recognized as a central player in a range of gastrointestinal (GI) disorders, as well as complications stemming from therapeutic interventions. This article presents an overview of the mechanisms of oxidative stress in GI conditions and highlights a link between oxidative insult and disruption to the enteric nervous system (ENS), which controls GI functions. The dysfunction of the ENS is characteristic of a spectrum of disorders, including neurointestinal diseases and conditions such as inflammatory bowel disease (IBD), diabetic gastroparesis, and chemotherapy-induced GI side effects. Neurons in the ENS, while essential for normal gut function, appear particularly vulnerable to oxidative damage. Mechanistically, oxidative stress in enteric neurons can result from intrinsic nitrosative injury, mitochondrial dysfunction, or inflammation-related pathways. Although antioxidant-based therapies have shown limited efficacy, recognizing the multifaceted role of oxidative stress in GI diseases offers a promising avenue for future interventions. This comprehensive review summarizes the literature to date implicating oxidative stress as a critical player in the pathophysiology of GI disorders, with a focus on its role in ENS injury and dysfunction, and highlights opportunities for the development of targeted therapeutics for these diseases.

Abstract
We previously reported that the ethanol extract from polished rice suppresses inflammation and the formation of aberrant crypt foci in the mouse colon and particularly focused on the plant sphingolipid glucosylceramide (GlcCer). Here, we investigated the effects of rice lipid fractions and GlcCer on differentiated Caco-2 cells treated with lipopolysaccharide (LPS), in particular, we evaluated the mechanism of action of GlcCer using related substances and metabolic enzyme inhibitors. Rice-derived polar lipids suppressed the LPS-induced reduction in the number of cells. The polar lipids with higher GlcCer content exerted a better effect than the other fractions. GlcCer-related substances reversed the LPS-induced reduction in the number of cells, and GlcCer-metabolic inhibitors, including a sphingosine kinase inhibitor, suppressed the beneficial effects of GlcCer-related substances. These results suggest that GlcCer is a rice component with intestinal protection. Secondly, GlcCer is metabolized during inflammation and protects intestinal cells by maintaining the sphingolipid levels in cells and producing sphingoid base-1-phosphate.

Multidirectional anti-melanoma effect of galactolipids (MGDG-1 and DGDG-1) from Impatiens parviflora DC. and their synergy with doxorubicin. Toxicol In Vitro 2021; 76:105231.

Abstract
The anti-melanoma potential of galactolipids: MGDG-1 and DGDG-1, isolated from Impatiens parviflora, and their synergistic effect with anticancer drug - doxorubicin (DOX) was investigated. Both compounds demonstrated time- and dose-dependent cytotoxicity against human melanoma cells of different metastatic potential. MGDG-1 was more effective than DGDG-1, with the highest activity against A375 cell line (IC50 = 15.14 μg/mL). Both compounds acted selectively, were devoid of hepatotoxicity or mutagenicity. Additionally, MGDG-1 proved to be a tyrosinase inhibitor. Co-administration of MGDG-1 and DGDG-1 with DOX revealed a synergistic cytotoxic effect on melanoma cells. The cytotoxicity of all tested MGDG-1/DOX and DGDG-1/DOX cocktails was considerably higher than that of each agent administered alone. MGDG-1/DOX (Mix3) reduced the viability of A375 melanoma cells almost totally and this effect was 2-fold more potent as compared to DOX alone. Our study indicates that the overall effect is enhanced with the increasing concentration of MGDG-1 in the cocktail. These results open up a possibility for lowering therapeutic doses of chemotherapeutics such as doxorubicin when co-administrated with galactolipids. Thus, MGDG-1 can be prospectively considered as multidirectional anti-melanoma agent and can be recommended for further in vitro and in vivo studies, especially in search for effective combined therapy.

Abstract
This trial evaluated the effects of thylakoid-rich spinach extract supplementation combined with a hypocaloric diet on body composition and serum levels of neopterin, chemerin, and omentin-1 in obese women with polycystic ovary syndrome (PCOS). In this randomized controlled trial, 48 obese women with PCOS, aged 20-45 years old, were recruited and randomly divided into thylakoid (n = 24) and placebo (n = 24) groups. They received a low-calorie diet with 5 g/day thylakoid-rich spinach extract or a low-calorie diet with 5 g/day placebo for 12 weeks. The mean age of the participants of the thylakoid group was 31.86 years, and the placebo group was 32.04 years. Thylakoid-rich spinach extract supplementation with a low-calorie diet increased serum levels of omentin-1 (10.90 vs. 3.87 ng/L; p < .001) and decreased fat mass (-5.19 vs. -1.35 kg; p < .001) and serum levels of neopterin (-0.66 vs. -0.38 nmol/L; p = .003) and chemerin (-41.24 vs. -11.26 ng/L; p < .001) in the thylakoid group compared to the placebo group. A significant improvement in omentin-1, chemerin, and neopterin by thylakoid-rich spinach extract supplementation was under the influence of weight change and insulin resistance status throughout the study. A significant decrease in the other anthropometric indices and insulin resistance was also observed in the thylakoid group, compared to the placebo group (p < .001, for all parameters). Thylakoid-rich spinach extract combined with a low-calorie diet increased circulating omentin-1 and decreased fat mass, abdominal obesity, as well as circulating chemerin, neopterin, and insulin in obese women with PCOS.

Abstract
Recently, the SARS-CoV-2 (COVID-19) pandemic virus has been spreading throughout the world. Until now, no certified drugs have been discovered to efficiently inhibit the virus. The scientists are struggling to find new safe bioactive inhibitors of this deadly virus. In this study, we aim to find antagonists that may inhibit the activity of the three major viral targets: SARS-CoV-2 3-chymotrypsin-like protease (6LU7), SARS-CoV-2 spike protein (6VYB), and a host target human angiotensin-converting enzyme 2 (ACE2) receptor (1R42), which is the entry point for the viral encounter, were studied with the prospects of identifying significant drug candidate(s) against COVID-19 infection. Then, the protein stability produced score of less than 0.6 for all residues of all studied receptors. This confirmed that these receptors are extremely stable proteins, so it is very difficult to unstable the stability of these proteins through utilizing individual drugs. Hence, we studied the combination and tricombination therapy between bioactive compounds which have the best binding affinity and some antiviral drugs like chloroquine, hydroxychloroquine, azithromycin, simeprevir, baloxavir, lopinavir, and favipiravir to show the effect of combination and tricombination therapy to disrupt the stability of the three major viral targets that are mentioned previously. Also, ADMET study suggested that most of all studied bioactive compounds are safe and nontoxic compounds. All results confirmed that caulerpin can be utilized as a combination and tricombination therapy along with the studied antiviral drugs for disrupting the stability of the three major viral receptors (6LU7, 6VYB, and 1R42).

Abstract
This work aimed at evaluating the inhibitory effect of ten natural bioactive compounds (1-10) as potential inhibitors of SARS-CoV-2-3CL main protease (PDB ID: 6LU7) and SARS-CoV main proteases (PDB IDs: 2GTB and 3TNT) by molecular docking analysis. The inhibitory effect of all studied compounds was studied with compared to some proposed antiviral drugs which currently used in COVID-19 treatment such as chloroquine, hydroxychloroquine, azithromycin, remdesivir, baloxvir, lopinavir, and favipiravir. Homology modeling and sequence alignment was computed to evaluate the similarity between the SARS-CoV-2-3CL main protease and other SARS-CoV receptors. ADMET properties of all studied compounds were computed and reported. Also, molecular dynamic (MD) simulation was performed on the compound which has the highest binding affinity inside 6LU7 obtained from molecular docking analysis to study it is stability inside receptor in explicit water solvent. Based on molecular docking analysis, we found that caulerpin has the highest binding affinity inside all studied receptors compared to other bioactive compounds and studied drugs. Our homology modeling and sequence alignment showed that SARS-CoV main protease (PDB ID: 3TNT) shares high similarity with 3CLpro (96.00%). Also, ADMET properties confirmed that caulerpin obeys Lipinski's rule and passes ADMET property, which make it a promising compound to act as a new safe natural drug against SARS-CoV-2-3CL main protease. Finally, MD simulation confirmed that the complex formed between caulerpin and 3CLpro is stable in water explicit and had no major effect on the flexibility of the protein throughout the simulations and provided a suitable basis for our study. Also, binding free energy between caulerpin and 6LU7 confirmed the efficacy of the caulerpin molecule against SARS-CoV-2 main protease. So, this study suggested that caulerpin could be used as a potential candidate in COVID-19 treatment.

Abstract
Spinach is prone to spoilage in the course of preservation. Spinach leaves stored at different temperatures for different durations will have varying degrees of freshness. In order to monitor the freshness of spinach leaves during storage, a rapid and non-destructive method—hyperspectral imaging technology—was applied in this study. Visible near-infrared reflectance (Vis-NIR) (380–1030 nm) and near-infrared reflectance (NIR) (874–1734 nm) hyperspectral imaging systems were used. Spinach leaves preserved at different temperatures with different durations (0, 3, 6, 9 days at 4 °C and 0, 1, 2 days at 20 °C) were studied. Principal component analysis (PCA) was adopted as a qualitative analysis method. The second-order derivative spectra were utilized to select effective wavelengths. Partial least squares discriminant analysis (PLS-DA), support vector machine (SVM), and extreme learning machine (ELM) were used to build models based on full spectra and effective wavelengths. All three models achieved good results, with accuracies above 92% for both Vis-NIR spectra and NIR spectra. ELM obtained the best results, with all accuracies reaching 100%. The overall results indicate the possibility of the freshness identification of spinach preserved at different temperatures for different durations using two kinds of hyperspectral imaging systems.

Abstract
BackgroundIntestinal mucositis is a major concern related with cancer therapy. It is well established that overproduction of reactive oxygen species and inflammatory mediators plays vital role in the pathogenesis of mucositis. The aim of the study was to investigate the modulatory effect of vitamin E (vit. E) on 5-fluorouracil (5-FU)-induced intestinal mucositis by targeting oxidative stress and inflammatory markers in rats. MethodsRats were randomly divided into four groups of six animals each. All four-group animals received normal standard diet and water throughout the experimental period which last up to 10 days. Rats were gavaged with vit. E (300 mg/kg b. wt.) daily for 10 days (day 1-10) and were given intraperitoneal injection of 5-FU (150 mg/kg b. wt.) or saline (control) on day 8 to induce mucositis. Results We found that vit. E supplementation ameliorated 5-FU-induced lipid peroxidation, myeloperoxidase activity, activation of nuclear factor κB, expression of cyclooxygenase-2, inducible nitric oxide synthase and mucin depletion. Vit. E administration also attenuated 5-FU-induced histological anomalies such as neutrophil infiltration, loss of cellular integrity, villus and crypt deformities. ConclusionsFindings of the study suggest that vit. E inhibits 5-FU-induced mucositis via modulation of oxidative stress, activation of redox sensitive transcription factor and its downstream targets.

Abstract
BACKGROUND The antineoplastic drug 5-fluoruracil (5-FU) is a pirimidine analog, which frequently induces potentially fatal diarrhea and mucositis. Cannabinoids reduce gastrointestinal motility and secretion and might prevent 5-FU-induced gut adverse effects. Here, we asked whether cannabinoids may prevent diarrhea and mucositis induced by 5-FU in the rat. METHODS Male Wistar rats received vehicle or the non-selective cannabinoid agonist WIN 55,212-2 (WIN; 0.5 mg kg-1 injection-1 , 1 injection day-1 , 4 consecutive days) by intraperitoneal (ip) route; on the first 2 days, animals received also saline or 5-FU (150 mg kg-1 injection-1 , cumulative dose of 300 mg kg-1 ). Gastrointestinal motor function was radiographically studied after barium contrast intragastric administration on experimental days 1 and 4. Structural alterations of the stomach, small intestine and colon were histologically studied on day 4. PAS staining and immunohistochemistry for Ki67, chromogranin A and CD163 were used to detect secretory, proliferating, and endocrine cells, and activated macrophages respectively. KEY RESULTS As shown radiographically, 5-FU induced significant gastric emptying delay (on days 1 and 4) and diarrhea (on day 4). WIN did not significantly alter the motility curves obtained for either control or 5-FU-treated animals but tended to reduce the severity of 5-FU-induced diarrhea and increased permanence of barium from day 1 to the beginning of day 4 in 5-FU-treated animals. 5-FU-induced mucositis was severe and not counteracted by WIN. CONCLUSIONS AND INFERENCES 5-FU-induced diarrhea, but not mucositis, was partly prevented by WIN at a low dose. Cannabinoids might be useful to prevent chemotherapy-induced diarrhea.

Abstract
BackgroundSpinacia oleracea known as spinach is a green-leafy vegetable consumed by people across the globe. It is reported to possess potent medicinal properties by virtue of its numerous antioxidant phytoconstituents, together termed as the natural antioxidant mixture (NAO). The present study compares the antacid effect of raw spinach juice with an antioxidant-rich methanolic extract of spinach (NAOE) in an artificial stomach model. MethodsThe pH of NAOE at various concentrations (50, 100 and 200 mg/mL) and its neutralizing effect on artificial gastric acid was determined and compared with that of raw spinach juice, water, the active control sodium bicarbonate (SB) and a marketed antacid preparation ENO. A modified model of Vatier's artificial stomach was used to determine the duration of consistent neutralization of artificial gastric acid for the test compounds. The neutralizing capacity of test compounds was determined in vitro using the classical titration method of Fordtran. Results NAOE (50, 100 and 200 mg/mL), spinach juice, SB and ENO showed significantly better acid-neutralizing effect, consistent duration of neutralization and higher antacid capacity when compared with water. Highest antacid activity was demonstrated by ENO and SB followed by spinach juice and NAOE200. Spinach juice exhibited an effect comparable to NAOE (200 mg/mL). ConclusionsThus, it may be concluded that spinach displays significant antacid activity be it in the raw juice form or as an extract in methanol.

Abstract
Damage to the mucous membrane is a serious issue associated with chemotherapy. Gastrointestinal (GI) toxicity is complex and multistep process and unregulated production of reactive oxygen species (ROS) and inflammatory mediators play vital role in the development of GI toxicity. In the present study we have investigated the attenuating potential of vitamin C (vit. C) on 5 fluorouracil (5-FU) induced GI toxicity by targeting oxidative stress and inflammatory markers in Sprague Dawley (SD) rats. Rats were gavaged with vit. C (500 mg/kg b. wt.) or vehicle daily (day 1-10) and were given intraperitoneal injection of 5-FU (150 mg/kg b. wt.) or saline (control) on day 8 to induce mucositis. We found that vit. C supplementation attenuated 5-FU induced lipid peroxidation, myeloperoxidase (MPO) activity, activation of NF-kB and expression of COX-2. Histological observations further supported the protective potential of vit. C against 5-FU induced intestinal anomalies such as neutrophil infiltration, loss of cellular integrity, villus and crypt deformities. Thus the biochemical, molecular and histological findings of the present study demonstrate that oxidative stress and inflammation play vital role in 5-FU induced GI toxicity and the inhibitory potential of vit. C is may be due to the modulation of oxidative stress, activation of redox sensitive transcription factor and also its downstream target molecules.

Abstract
Gastrointestinal mucositis induced during cancer treatment is considered a serious dose-limiting side effect of chemotherapy and/or radiotherapy. Frequently, interruption of the cancer treatment due to this pathology leads to a reduction in cure rates, increase of treatment costs and decrease life quality of the patient. Natural products such as Bidens pilosa L. (Asteraceae), represent a potential alternative for the treatment of mucositis given its anti-inflammatory properties. In this study, B. pilosa glycolic extract was formulated (BPF) with poloxamer, a mucoadhesive copolymer, was used for treatment of 5-fluorouracil (5-FU)-induced mucositis in mice. As expected, animals only treated with 5-FU (200 mg/kg) presented marked weight loss, reduction of intestinal villi, crypts and muscular layer, which was associated with severe disruption of crypts, edema, inflammatory infiltrate and vacuolization in the intestinal tissue, as compared to the control group and healthy animals only treated with BPF. On the other hand, the treatment of intestinal mucositis-bearing mice with BPF (75, 100 or 125 mg/kg) managed to mitigate clinical and pathologic changes, noticeably at 100 mg/kg. This dose led to the restoration of intestinal proliferative activity through increasing Ki-67 levels; modulated the expression of Bax, Bcl2 and p53 apoptotic markers protecting intestinal cells from cell death. Moreover, this treatment regulated lipid peroxidation and inflammatory infiltration. No acute toxic effects were observed with this formulation. This work demonstrated that BPF was safe and effective against 5-FU-induced intestinal mucositis in mice. Additional studies are already in progress to further characterize the mechanisms involved in the protective effects of this technological formulation toward the development of a new medicine for the prevention and treatment of intestinal injury in patients undergoing chemotherapy/radiotherapy.

Abstract
Objective: The aim of this study was to evaluate the effect of boron on 5-fluorouracil (5-FU)–induced oral mucositis in rats. Materials and Methods: Sixty-four male Wistar albino rats were injected with 5-FU on days 1 and 3. The right cheek pouch mucosa was scratched with the tip of an 18-G needle, dragged twice in a linear movement, on days 3 and 5. The animals were randomly divided into two groups of 32: boron group (BG) and control group (CG). Rats in the CG did not receive any treatment, whereas the others were fed boron (3 mg·kg-1·day-1) by gavage. The animals were sacrificed on day 3 (n = 8), 6 (n = 8), 9 (n = 8), and 12 (n = 8), and the cheek pouch was removed for histopathological analysis. Results: On day 3, both groups showed necrosis and active inflammation, but the inflammation was mild in CG and moderate in BG. On day 6, both BG and CG showed necrosis; in the CG, there was moderate inflammation, and in the BG, there was severe inflammation and granulation tissue around the necrotic area. On day 9, re-epithelization began in both groups, and there were no differences between groups. Re-epithelization was complete in both groups on day 12. Conclusion: We found no beneficial effect of boron in healing oral mucositis. Additional research is warranted to elucidate the pathogenic inflammatory mechanisms involved in mucositis and the prophylactic and therapeutic roles of antioxidants.

Live and heat-killed Lactobacillus rhamnosus GG upregulate gene expression of pro-inflammatory cytokines in 5-fluorouracil-pretreated Caco-2 cells. Support Care Cancer 2014; 22:1647-54.

Abstract
PURPOSE This study investigates whether post-chemotherapeutic use of live and heat-killed Lactobacillus rhamnosus GG can modulate the expression of three pro-inflammatory cytokines in 5-fluorouracil (5-FU)-induced intestinal mucositis in vitro. METHODS Live L. rhamnosus GG and heat-killed L. rhamnosus GG were observed using scanning electron microscopy. To establish the duration required for optimal expression of tumor necrosis factor-α (TNF-α), monocyte chemotactic protein-1 (MCP-1), and interleukin-12 (IL-12), 5 μM of 5-FU was selected to treat 10-day-old Caco-2 cells for 4, 6, 8, and 24 h. Caco-2 cells were treated with 5-FU (5 μM) for 4 h, followed by the administration of live L. rhamnosus GG (multiplicity of infection = 25), and heat-killed L. rhamnosus GG for 2 and 4 h. Finally, total cellular RNA was isolated to quantify mRNA expression of TNF-α, MCP-1, and IL-12 using real-time PCR. RESULTS The results demonstrated that heat-killed L. rhamnosus GG remained structurally intact with elongation. A biphasic upregulated expression of TNF-α, MCP-1, and IL-12 was observed in 5-FU-treated Caco-2 cells at 4 and 24 h. Compared to non-L. rhamnosus GG controls in 5-FU-pretreated Caco-2 cells, a 2-h treatment of heat-killed L. rhamnosus GG significantly upregulated the MCP-1 expression (p < 0.05), and both live and heat-killed L. rhamnosus GG treatments lasting 4 h upregulated the TNF-α and MCP-1 expression (p < 0.05). Only live L. rhamnosus GG upregulated the IL-12 expression (p < 0.05). CONCLUSIONS Post-chemotherapeutic use of live or heat-killed L. rhamnosus GG can upregulate the gene expression of 5-FU-induced pro-inflammatory cytokines in Caco-2 cells. Human intestinal epithelium may be vulnerable to the post-chemotherapeutic use of L. rhamnosus GG in 5-FU-induced mucositis that requires further in vivo studies for clarification.

Abstract
Mucositis is a common side-effect of cancer chemotherapy and radiotherapy. Features of mucositis include erythema, ulceration, and inflammation of the gastrointestinal tract accompanied by clinical symptoms of abdominal pain and digestive disturbances. New treatment strategies are required. Experimental evidence is accumulating showing therapeutic promise for new nutraceutical agents including probiotic bacteria, probiotic-derived factors, prebiotics, and plant extracts. However, the targeted development of new combinations of these agents (synbiotics) to combat mucositis remains largely unexplored. The current review addresses the potential for these nutraceutical agents to reduce the severity of chemotherapy-damaged mucositis by strategically aligning their underlying mechanism of action with features of mucositis pathogenesis. The potential for certain plant extracts to act as prebiotics, in combination with probiotics or their derived factors, is further investigated. These unique synbiotic formulations could form the basis of a new naturally sourced adjunctive approach to cancer chemotherapy.

Abstract
The pathogenesis of chemotherapy-induced gastrointestinal mucositis is not fully elucidated, which makes it extremely difficult to develop effective interventions. Recently, the use of animal models of chemotherapy-induced gastrointestinal mucositis has led to advances in the understanding of cellular mechanisms and clinical pharmacology of various types of chemotherapy drugs. Tumor-bearing models, non-tumor-bearing models, transgenic models and gene knockout models have been developed to assess the effect of chemotherapy on chemotherapy-induced gastrointestinal mucositis. In this paper, we comprehensively analyze the advantages and disadvantages of various methods for developing chemotherapy-induced gastrointestinal mucositis to provide a reference for the choice of animal models for future research of chemotherapy-associated mucosal toxicity and the underlying mechanisms.
