Abstract
Ischemic heart diseases such as myocardial infarction (MI) are a global health problem and a leading cause of mortality worldwide. Angiogenesis is an important approach for myocardial healing following ischemia. Thus, this study aimed to explore the potential cardiac angiogenic effects of selenium (Se), alone and in combination with the tumor necrosis factor-alpha inhibitor, pentoxifylline (PTXF), via Akt/HIF-1α signaling. MI was induced in rats using two subcutaneous doses of isoprenaline (ISP) at a 24-h interval (150 mg/kg). One week later, rats were orally given Se (150 µg/kg/day), PTXF (50 mg/kg/day), or Se/PTXF combination. ISP-induced myocardial damage was evident by increased HW/TL ratios, ST segment elevation, and increased serum levels of CK-MB, LDH, and troponin-I. ISP increased the cardiac levels of the lipid peroxidation marker MDA; the pro-inflammatory cytokines IL-6, IL-1β, and TNF-α; and the pro-apoptotic protein Bax and caspase-3. In contrast, the cardiac levels of the antioxidant markers GSH and SOD and the anti-apoptotic marker Bcl-2 were reduced. Furthermore, ISP markedly increased the cardiac levels of p-Akt and HIF-1α proteins and the cardiac gene expression of ANGPT-1, VEGF, and FGF-2. Treatment with Se both alone and in combination with PTXF ameliorated the ISP-induced myocardial damage and further increased cardiac angiogenesis via Akt/HIF-1α signaling. Se/PTXF combined therapy was more beneficial than individual treatments. Our study revealed for the first time the cardiac angiogenic effects of Se both alone and in combination with PTXF in myocardial infarction, suggesting that both may be promising candidates for clinical studies.

Abstract
BACKGROUND Bronchial asthma is a severe respiratory condition characterized by airway inflammation, remodeling, and oxidative stress. β-Glucan (BG) is a polysaccharide found in fungal cell walls with powerful immunomodulatory properties. This study examined and clarified the mechanisms behind BG's ameliorativeactivitiesin an allergic asthma animal model. METHOD BG was extracted from Chaga mushroom and characterized using FT-IR, UV-visible, zeta potential, and 1H NMR analysis. The mice were divided into five groups, including control, untreated asthmatic, dexamethasone (Dexa)-treated (1 mg/kg), and BG (30 and 100 mg/kg)-treated groups. RESULTS BG treatment reduced nasal scratching behavior, airway-infiltrating inflammatory cells, and serum levels of IgE significantly. Additionally, BG attenuated oxidative stress biomarkers by lowering malonaldehyde (MDA) concentrations and increasing the levels of reduced glutathione (GSH), glutathione peroxidase (GPx), and catalase (CAT). Immunohistochemical and flow cytometric analyses have confirmed the suppressive effect of BG on the percentage of airway-infiltrating cytotoxic CD8+ T cells. CONCLUSION The findings revealed the role of CD8+ T cells in the pathogenesis of asthma and the role of BG as a potential therapeutic agent for asthma management through the suppression of airway inflammation and oxidative stress.

Abstract
In this study, the protective efficacy of pentoxifylline (PTX) as a xanthine derivative against arsenic trioxide (ATO)-induced kidney and liver damage in mice was investigated. Thirty-six mice were divided into six groups, receiving intraperitoneal injections of saline, ATO, PTX, or a combination for four weeks. Blood samples were analyzed for serum biochemistry, while hepatic tissue underwent examination for histopathological changes and assessment of oxidative stress markers and antioxidant gene expression through Real-Time PCR. ATO exposure significantly increased serum markers (creatinine, ALT, BUN, ALP, AST) and induced histopathological changes in the liver. Moreover, it elevated renal and hepatic nitric oxide (NO) and lipid peroxidation (LPO) levels, and reduced antioxidant enzyme expression (CAT, GSR, GPx, MPO, SOD), total thiol groups (TTGs), and total antioxidant capacity (TAC). Conversely, PTX treatment effectively lowered serum hepatic and renal markers, improved antioxidant markers, and induced histopathological alterations. Notably, PTX did not significantly affect renal and hepatic NO levels. These findings suggest that PTX offers therapeutic potential in mitigating liver and acute kidney injuries induced by various insults, including exposure to ATO.

Abstract
Arsenic (As) is a metal with potentially toxic effects on different organisms. Hydrogen sulfide (H2S) plays a vital role in mitigating heavy metal toxicity by reducing oxidative stress in plants and animals. However, the role of H2S in alleviating arsenic toxicity in yeast cells remains unclear. In this study, the role of NaHS (exogenous physiological H2S) in alleviating As-induced yeast cell death was investigated. Yeast cells in the logarithmic phase were pretreated with 0.05 mmol/L NaHS for 6 h, and then incubated in the YPD medium with or without 1 mmol/L As. After 12 h of treatment, relative survival rate, H2S content, oxidative stress biomarkers, and antioxidant machinery were measured. Our results showed that sodium arsenite-induced yeast cell death and pretreatment with 0.05 mmol/L NaHS significantly alleviated sodium arsenite-induced cell death. Under sodium arsenite conditions, the levels of intracellular reactive oxygen species (ROS) and malondialdehyde (MDA) increased, accompanied by the inhibition of the catalase (CAT) activity and the downregulation of CTT1 expression. However, the activities of the superoxide dismutase (SOD) and glutathion peroxidase (GPX) increased, and the expression of SOD1 and GPX2 was markedly upregulated in the group treated with sodium arsenite. When yeast cells were pretreated with NaHS, the intracellular ROS and MDA levels decreased significantly, and the activities of SOD, CAT, and GPX increased significantly. This was associated with a significant increase in relative survival rate and H2S content compared to the arsenic treatment alone. Our findings indicate that NaHS alleviates sodium arsenite-induced yeast cell death, mainly by enhancing the antioxidant defense system.

Abstract
Heavy metals are among the most important environmental pollutions used in various industries. Their extensive use has increased human susceptibility to different chronic diseases. Toxic metal exposure, especially cadmium, arsenic, and lead, causes oxidative damages, mitochondrial dysfunction, and genetic and epigenetic modifications. Meanwhile, thymoquinone (TQ) is an effective component of Nigella sativa oil that plays an important role in preventing the destructive effects of heavy metals. The present review discusses how TQ can protect various tissues against oxidative damage of heavy metals. This review is based on the research reported about the protective effects of TQ in the toxicity of heavy metals, approximately the last 10 years (2010-2021). Scientific databases, including Scopus, Web of Science, and PubMed, were searched using the following keywords either alone or in combination: cadmium, arsenic, lead, TQ, and oxidative stress. TQ, as a potent antioxidant, can distribute to cellular compartments and prevent oxidative damage of toxic metals. However, depending on the type of toxic metal and the carrier system used to release TQ in biological systems, its therapeutic dosage range may be varied.

Abstract
In the current study, silibinin-loaded nanostructured lipid carriers (Sili-NLCs) was synthesized, and the hepatoprotective effectiveness of Sili-NLCs against diazinon (DZN)-induced liver damage in male mice was evaluated. The emulsification-solvent evaporation technique was applied to prepare Sili-NLCs, and characterized by using particle size, zeta potential, entrapment efficacy (EE %), in vitro drug release behavior, and stability studies. In vivo, studies were done on male mice. Hepatotoxicity in male mice were induced by DZN (10 mg/kg/day, i.p.). Four groups treated with silibinin and Sili-NLCs with the same doses (100 and 200 mg/kg, p.o.). On 31th days, serum and liver tissue samples were collected. Alanine (ALT) and aspartate (AST) aminotransferase levels, oxidative stress biomarkers, inflammatory cytokines, and histopathological alterations were assessed. The Sili-NLCs particle size, zeta potential, polydispersity index (PDI), and EE % were obtained at 220.8 ± 0.86 nm, -18.7 ± 0.28 mV, 0.118 ± 0.03, and 71.83 ± 0.15%, respectively. The in vivo studies revealed that DZN significantly increased the serum levels of AST, ALT, hepatic levels of lipid peroxidation (LPO), and tumor necrosis factor-α (TNF-α), while decreased the antioxidant defense system in the mice's liver. However, Sili-NLCs was more effective than silibinin to return the aforementioned ratio toward the normal situation, and these results were well correlated with histopathological findings. Improvement of silibinin protective efficacy and oral bioavailability by using NLCs caused to Sili-NLCs can be superior to free silibinin in ameliorating DZN-induced hepatotoxicity in male mice.

Abstract
Inhalation of high concentrations of phosgene often causes pulmonary edema, which obstructs the airway and causes tissue hypoxia. There is currently no specific antidote. This study was performed to investigate the effect behind pentoxifylline (PTX) treatment for phosgene-induced lung injury in rat models. Rats were exposed to phosgene. The protein levels of hypoxia-inducible factor-1α (HIF-1α), vascular endothelial growth factor (VEGF), and occludin proteins in lung tissue were determined. The effect of both prophylactic and therapeutic administration of PTX (50 mg/kg and 100 mg/kg) was evaluated. The lung permeability index and HIF-1α protein level increased, the arterial blood oxygenation index (PaO2/FIO2 ratio) and occludin protein level decreased significantly 6 h after phosgene exposure (P < 0.05). PTX exerted protective effects by HIF-1α-VEGF-occludin signaling pathway to some extent. Moreover, prophylactic, but not therapeutic administration of PTX (100 mg/kg), exhibited a significant protective effect. Pretreatment with PTX protected against phosgene-induced lung injury, possibly by inhibiting differential expression of HIF-1α, VEGF, and occludin.

Abstract
Severe acute respiratory disease is associated with chronic secondary infections that exacerbate symptoms and mortality. So far, many drugs have been introduced to treat this disease, none of which effectively control the coronavirus. Numerous studies have shown that mitochondria, as the center of cell biogenesis, are vulnerable to drugs, especially antibiotics. Antibiotics were widely prescribed during the early phase of the pandemic. We performed a literature review to assess the reasons, evidence, and practices on the use of antibiotics in coronavirus disease 2019 (COVID-19) in- and outpatients. The current research found widespread usage of antibiotics, mostly in an empirical context, among COVID-19 hospitalized patients. The effectiveness of this approach has not been established. Given the high death rate linked with secondary infections in COVID-19 patients and the developing antimicrobial resistance, further study is urgently needed to identify the most appropriate rationale for antibiotic therapy in these patients.

Abstract
Over the past few decades, clinical trials conducted worldwide have demonstrated the efficacy of arsenic trioxide (ATO) in the treatment of relapsed acute promyelocytic leukemia (APL). Currently, ATO has become the frontline treatments for patients with APL. However, its therapeutic applicability is severely constrained by ATO-induced cardiac side effects. Any cardioprotective agents that can ameliorate the cardiac side effects and allow exploiting the full therapeutic potential of ATO, undoubtedly gain significant attention. The knowledge and use of natural products for evidence-based therapy have grown rapidly in recent years. Here we discussed the potential mechanism of ATO-induced cardiac side effects and reviewed the studies on cardiac side effects as well as the research history of ATO in the treatment of APL. Then, We summarized the protective effects and underlying mechanisms of natural products in the treatment of ATO-induced cardiac side effects. Based on the efficacy and safety of the natural product, it has a promising future in the development of cardioprotective agents against ATO-induced cardiac side effects.

Abstract
AIM Intrahepatic cholestasis is a common pathological condition of several types of liver disorders. In this study, we aimed to investigate the regulatory effects of quercetin (QU) on selected phosphodiesterase inhibitors against alpha-naphthyl isothiocyanate (ANIT)-induced acute intrahepatic cholestasis. METHODS Cholestasis was induced in Wistar albino rats by ANIT as a single dose (60 mg/kg; P·O.). QU (50 mg/kg, daily, P·O.), sildenafil (Sild; 10 mg/kg, twice daily, P·O.), and pentoxifylline (PTX; 50 mg/kg, daily, P.O.) were evaluated either alone or in combinations for 10 days for their antioxidant, anti-inflammatory, and anti-pyroptotic effects. RESULTS ANIT produced a prominent intrahepatic cholestasis as evidenced by a significant alteration in liver functions, histological structure, inflammatory response, and oxidative stress biomarkers. Furthermore, up-regulation of NF-κB-p65, TLR4, NLRP3, cleaved caspase-1, IKK-β, and IL-1β concurrently with down-regulation of Nrf-2, HO-1, and PPAR-γ expressions were observed after ANIT. QU, Sild, or PTX treatment significantly alleviated the disturbance induced by ANIT. These findings were further supported by the improvement in histopathological features. Additionally, co-administration of QU with Sild or PTX significantly improved liver defects due to ANIT as compared to the individual drugs. SIGNIFICANCE Combined QU with Sild or PTX exhibited promising hepatoprotective effects and anti-cholestatic properties through modulation of Nrf2/ARE, TLR4/NF- κB, and NLRP3/IL-1β signaling pathways.

PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 106:154368. [PMID: 35994850 DOI: 10.1016/j.phymed.2022.154368] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Revised: 05/30/2022] [Accepted: 07/31/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Nonalcoholic fatty liver (NAFL), recognized as one of the most common causes of chronic liver diseases, is increasingly prevalent worldwide. Pentoxifylline, a derivative of theobromine extracted from Theobroma cacao and tea, has been studied for effects on blood viscosity, tissue oxygenation and inflammation. However, its effects on hepatic lipid accumulation and the potential mechanisms remain unclear. PURPOSE This study aimed to investigate the therapeutic effects of pentoxifylline on high-fat diet-induced NAFL and to explore the corresponding molecular mechanisms. METHODS NAFL mice were injected with or without 25, 50 or 100 mg/kg pentoxifylline for 2 weeks. Hepatic steatosis was observed by haematoxylin-eosin staining and Oil Red O staining, the levels of serum total cholesterol, triglyceride were detected by biochemical kits, and insulin resistance was evaluated by glucose and insulin tolerance tests. In addition, we measured the frequencies of macrophage and its polarization subsets in the liver using flow cytometry and immunofluorescence. The expressions of proteins associated with macrophage polarization signaling pathways were assessed by Western blotting and flow cytometry histograms. Molecular docking and cellular thermal shift assay were conducted to identify and verify the target protein of pentoxifylline in macrophage. RESULTS Pentoxifylline significantly alleviated hepatic lipid accumulation, reduced blood lipid levels and improved insulin resistance. Strikingly, the excessive M1 macrophages in NAFL development was abolished by pentoxifylline. And pentoxifylline was further evidenced it failed to reduce hepatocyte lipid accumulation in the absence of macrophages in vitro. Mechanistically, pentoxifylline competed with LPS for binding to toll-like receptor 4, dramatically inhibiting the TLR4/MyD88/NF-κB signaling pathway. CONCLUSION Pentoxifylline attenuated NAFL by inhibiting hepatic macrophage M1 polarization, indicating that pentoxifylline could be a therapeutic candidate for NAFL. This study first observed that M1 macrophages were increased in NAFL mice and then revealed the molecule targeted by pentoxifylline. In addition, we provided evidence that macrophage targeting may be an emerging strategy for NAFL treatment.

PESTICIDE BIOCHEMISTRY AND PHYSIOLOGY 2022; 188:105278. [PMID: 36464381 DOI: 10.1016/j.pestbp.2022.105278] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Revised: 10/25/2022] [Accepted: 11/01/2022] [Indexed: 06/17/2023]
Abstract
Phlebotomy is an effective method in the prevention and treatment of some poisonings, among which iron deficiency is a well-known consequence. Given the role of iron in paraquat (PQ) toxicity, the present study investigated the effectiveness of phlebotomy in PQ pulmonary toxicity. After conducting preliminary studies, the duration time of phlebotomy was set to be seven days. Then, the mice were divided into nine separate groups. Groups 1-3 received a single dose of normal saline, and 5 and 10 mg/kg of PQ, respectively, and phlebotomy was not performed on them (NPG status). The animals in groups 4-6 first underwent phlebotomy for seven days and then received a single dose of normal saline, and 5 and 10 mg/kg of PQ (PBPT status). Groups 7-9 first received a single dose of normal saline, and 5 and 10 mg/kg of PQ and then underwent phlebotomy for seven days (PAPT status). Seven days after acute exposure to PQ, the animals were anesthetized and biochemical biomarkers as well as lung tissue changes were evaluated. The findings showed that phlebotomy before and after PQ toxicity significantly decreased serum iron compared to NPG condition. In the PBPT status, phlebotomy could prevent PQ toxicity by increasing the activity of catalase and superoxide dismutase (SOD) and decreasing the activity of myeloperoxidase (MPO), and the levels of hydroxyproline and lipid peroxidation in the lung tissue. In the PAPT status, a significant improvement was observed in SOD and MPO activities compared to the NPG status. Confirming the biochemical findings, the histological results indicated higher effectiveness of phlebotomy in preventing PQ toxicity (PBPT) compared to its therapeutic effects (PAPT). Considering the role of iron in PQ toxicity, it appears that the reduction of serum iron levels during phlebotomy can be effective in preventing lung injuries caused by PQ and improving the performance of the pulmonary antioxidant system.

Abstract
Melatonin is an indoleamine hormone secreted by the pineal gland. It has antioxidation and anti-apoptosis effects and a clear protective effect against cardiovascular diseases. Our previous studies demonstrated that embryonic exposure to sodium arsenite (NaAsO2) can lead to an abnormal cardiac development. The aim of this study was to determine whether melatonin could protect against NaAsO2-induced generation of reactive oxygen species (ROS), oxidative stress, apoptosis, and abnormal cardiac development in a zebrafish (Danio rerio) model. We found that melatonin decreased NaAsO2-induced zebrafish embryonic heart malformations and abnormal heart rates at a melatonin concentration as low as 10−9 mol/L. The NaAsO2-induced oxidative stress was counteracted by melatonin supplementation. Melatonin blunted the NaAsO2-induced overproduction of ROS, the upregulation of oxidative stress-related genes (sod2, cat, gpx, nrf2, ho-1), and the production of antioxidant enzymes (Total SOD, SOD1, SOD2, CAT). Melatonin attenuated the NaAsO2-induced oxidative damage, DNA damage, and apoptosis, based on malonaldehyde and 8-OHdG levels and apoptosis-related gene expression (caspase-3, bax, bcl-2), respectively. Melatonin also maintained the control levels of heart development-related genes (nkx2.5, sox9b) affected by NaAsO2. In conclusion, melatonin protected against NaAsO2-induced heart malformations by inhibiting the oxidative stress and apoptosis in zebrafish.

The Hydroalcoholic Extract of Nasturtium officinale Reduces Lung Inflammation and Oxidative Stress in an Ovalbumin-Induced Rat Model of Asthma. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:5319237. [PMID: 35774748 PMCID: PMC9239788 DOI: 10.1155/2022/5319237] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/08/2022] [Revised: 05/02/2022] [Accepted: 05/18/2022] [Indexed: 01/09/2023]
Abstract
Background Asthma is known as a disease that causes breathing problems in children and adults and is also associated with chronic inflammation and oxidative stress of the airways. Nasturtium officinale (NO) possesses a wide range of pharmacological properties, particularly anti-inflammation and antioxidant potentials. Thus, this study for the first time was aimed to investigate anti-inflammatory and antioxidative activities of NO extract (NOE) in an ovalbumin-induced rat model of asthma. Materials and Methods Forty-four male Wistar rats were sensitized with ovalbumin (OVA) to induce asthma symptoms. The animals were allocated into five groups: control (C), asthmatic (A), A + NOE (500 mg/kg), NOE (500 mg/kg), and A + dexamethasone (DX, 2.5 mg/kg). After 7 days, blood and tissue samples were taken from the rats. Then, the level of inflammatory markers, oxidative stress parameters, and antioxidant enzymes activity were measured. Results The obtained results showed that OVA-sensitive rats significantly increased the levels of pro-inflammatory cytokines IL-1B, TGF-β, and SMA-α compared to the control group (p < 0.05), while treatment with NOE remarkably reduced the SMA-α gene expression compared to the asthma group (p < 0.05). Furthermore, it decreased the expression of IL-1B and TNF-α genes, although it was not statistically significant. The level of glutathione peroxidase (GPX) significantly reduced in A group compared to the C group (p < 0.05), whereas NOE administration significantly increased this marker (p < 0.05). Moreover, NOE attenuated inflammation and alveolar injury in the lungs of OVA-sensitive rat compared to the nontreated A group. Conclusions Overall, our findings demonstrated that NOE somewhat is able to reduce airway inflammation by reducing inflammatory and increasing GPX activity. Indeed, further experiments investigating the impact of different extract doses are needed to confirm the antioxidant and anti-inflammatory effects of NOE.

Abstract
BACKGROUND AND OBJECTIVE Nephrotoxicity induced by the chemotherapeutic drug arsenic trioxide (ATO) is often overlooked, and the underlying mechanisms remain poorly understood. Based on network pharmacology and experimental validation, this study investigates the protection of 6-gingerol (6G) against ATO-induced nephrotoxicity and the potential mechanisms. METHODS We screened and collected 6G and disease-related targets and then imported the interaction targets into a String database to construct protein-protein interaction (PPI) networks. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were performed using the Database for Annotation, Visualization and Integrated Discovery (DAVID). Mice were injected intraperitoneally with ATO (5 mg/kg) for seven days to induce nephrotoxicity, and then the histological morphology of the kidneys, biochemical indices of serum and tissues, and associated protein expressions were observed. RESULTS The network pharmacology results revealed that the effects of 6G against nephrotoxicity are closely related to apoptosis, and the MAPKs pathway was screened for validation. In animal experiments, 6G improved the histopathological morphology of the kidneys, reduced the levels of renal function markers, enhanced antioxidant activity, and decreased the levels of inflammation. Furthermore, 6G reduced apoptotic cells in kidney tissues, decreased the levels of Bax and c-Caspase-3, and increased the level of Bcl-2. The results of immunohistochemistry and western blotting revealed that 6G significantly inhibited the expressions of p-p38, p-ERK, and p-JNK. CONCLUSION The results comprehensively demonstrate the protective effects of 6G against ATO-induced nephrotoxicity. The effects are related to anti-oxidant, anti-inflammatory, and anti-apoptotic properties, possibly through inhibition of the MAPKs pathway.

Abstract
The wound is a break in the integrity of the skin produced by injury, illness, or operation. Wound healing is an essential dynamic biological/physiological process that occurs in response to tissue damage. The huge health, economic, and social effects of wounds on patients and societies necessitate the research to find novel potential therapeutic agents in order to promote wound healing. Postbiotics, the newest member of the biotics family, are valuable functional bioactive substances produced by probiotics through their metabolic activity, which have several beneficial properties, including immunomodulatory, anti-inflammatory, antimicrobial, and angiogenesis characteristics, resulting in acceleration of wound healing. In the current study, three topical cold cream formulations containing postbiotics obtained from Lactobacillus fermentum, Lactobacillus reuteri, or Bacillus subtilis sp. natto probiotic strains were prepared. The effectiveness and wound healing activity of the developed postbiotics cold cream formulations were investigated compared to cold cream without postbiotics and no treatment via wound closure investigation, hydroxyproline content assay, and histological assessment in 25 Sprague Dawley rats divided into five groups. Interestingly, analysis of the results revealed that all three formulations containing postbiotics significantly accelerated the wound healing process. However, in general, the Bacillus subtilis natto cold cream manifested a better wound healing property. The pleasing wound healing characteristics of the topical postbiotics cold creams through the in vivo experiment suggest that formulations containing postbiotics can be considered as a promising nominee for wound healing approaches.

Abstract
Due to the increase in the aged population and increased life expectancy, the underlying mechanisms involved in the aging process and cell senescence and the ways for modulating these processes in age-related diseases become important. One of the main mechanisms involved in aging and cell senescence, especially in the diseases related to aging, is the oxidative stress process and the following inflammation. Hence, the effects of antioxidants are highlighted in the literature due to their beneficial impacts on inhibiting telomere shortening or DNA damage and other processes related to aging and cell senescence in age-related diseases. Dietary components, foods, and dietary patterns rich in antioxidants can modulate the aging process and delay the progression of some chronic diseases such as cardiovascular diseases, diabetes, and Alzheimer's disease. Foods high in polyphenols, vitamin C, or carotenoids, olive oil, seeds, nuts, legumes, dietary supplements such as CoQ10, and some other dietary factors are the most important nutritional sources that have high antioxidant contents which can positively affect cell senescence and disease progression. Plant dietary patterns including Mediterranean diets can also inhibit telomere shortening following oxidative damages, and this can delay cell aging and senescence in age-related diseases. Further, olive oil can inhibit protein aggregation in Alzheimer's disease. It can be concluded that nutrition can delay the process of cell senescence in age-related diseases via inhibiting oxidative and inflammatory pathways. However, more studies are needed to better clarify the underlying mechanisms of nutrition and dietary components on cell senescence, aging, and disease progression, especially those related to age.
