Presto P, Sehar U, Kopel J, Reddy PH. Mechanisms of pain in aging and age-related conditions: Focus on caregivers. Ageing Res Rev 2024; 95:102249. [PMID: 38417712 DOI: 10.1016/j.arr.2024.102249] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Revised: 02/13/2024] [Accepted: 02/22/2024] [Indexed: 03/01/2024]
Abstract
Pain is a complex, subjective experience that can significantly impact quality of life, particularly in aging individuals, by adversely affecting physical and emotional well-being. Whereas acute pain usually serves a protective function, chronic pain is a persistent pathological condition that contributes to functional deficits, cognitive decline, and emotional disturbances in the elderly. Despite substantial progress that has been made in characterizing age-related changes in pain, complete mechanistic details of pain processing mechanisms in the aging patient remain unknown. Pain is particularly under-recognized and under-managed in the elderly, especially among patients with Alzheimer's disease (AD), Alzheimer's disease-related dementias (ADRD), and other age-related conditions. Furthermore, difficulties in assessing pain in patients with AD/ADRD and other age-related conditions may contribute to the familial caregiver burden. The purpose of this article is to discuss the mechanisms and risk factors for chronic pain development and persistence, with a particular focus on age-related changes. Our article also highlights the importance of caregivers working with aging chronic pain patients, and emphasizes the urgent need for increased legislative awareness and improved pain management in these populations to substantially alleviate caregiver burden.

Saleem A, Khalid H, Akhtar MF, Zeb A. Appraisal of anti-arthritic potential of Coronopus didymus (L.) Sm. aqueous extract and its safety study in Wistar rats. Inflammopharmacology 2023; 31:3167-3182. [PMID: 37962695 DOI: 10.1007/s10787-023-01374-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2023] [Accepted: 10/09/2023] [Indexed: 11/15/2023]
Abstract
The current study aimed to find out the anti-arthritic activity and safety study of Coronopus didymus aqueous extract (CDAE) as well as its chemical characterization by HPLC-DAD. Safety study including acute and subacute toxicity studies of the plant aqueous extract was also performed. In complete Freund's adjuvant-induced arthritic model (CFA), 0.15 ml CFA was injected in the left hind paw at day 1 in all rats except normal rats. Treatment with CDAE at 200, 400, and 800 mg/kg and methotrexate (1 mg/kg) was administered at day 8 and continued till 28th day using oral gavage. The CDAE considerably (p < 0.05) reduced the paw swelling and arthritic score, and reinstated the body weight and blood parameters. The CDAE considerably modulated superoxide dismutase, catalase, reduced glutathione, and malondialdehyde level in liver homogenate in contrast to disease control. The CDAE at 400 mg/kg considerably reduced IL-6, IL -1β, COX-2, and NF-ĸβ, whereas elevated IL-10, IL-4, and I-kappa β as equated to disease and standard groups. The LD50 of CDAE > 2000 mg/kg. In subacute toxicity study, CDAE at 200-800 mg/kg did not exhibit clinical signs of toxicity, mortality, hematological, biochemical, and histological alteration in the liver heart, kidney, and lungs in contrast to the normal group. It was concluded that the presence of delphinidine-3-glucoside, diosmetin, 3-feruloyl-4,5-dicaffeoyl quinic acid, and gallic acid in CDAE might be accountable for its anti-arthritic activity and safe use for a long period.

Abstract
Liquiritigenin (LTG) and its bioprecursor isoliquiritigenin(ISL), the main bioactives from roots of Glycyrrhiza genus are progressively documented as a potential pharmacological agent for the management of chronic diseases. The aim of this study was to evaluate the pharmacological potential of liquiritigenin, isoliquiritigenin rich extract of Glycyrrhiza glabra roots (IVT-21) against the production of pro-inflammatory cytokines from activated macrophages as well as further validated the efficacy in collagen-induced arthritis model in rats. We also performed the safety profile of IVT-21 using standard in-vitro and in-vivo assays. Results of this study revealed that the treatment of IVT-21 and its major bioactives (LTG, ISL) was able to reduce the production of pro-inflammatory cytokines (TNF-α, IL-6) in LPS-activated primary peritoneal macrophages in a dose-dependent manner compared with vehicle-alone treated cells without any cytotoxic effect on macrophages. In-vivo efficacy profile against collagen-induced arthritis in Rats revealed that oral administration of IVT-21 significantly reduced the arthritis index, arthritis score, inflammatory mediators level in serum. IVT-21 oral treatment is also able to reduce the NFкB-p65 expression as evidence of immunohistochemistry in knee joint tissue and mRNA level of pro-inflammatory cytokines in paw tissue in a dose-dependent manner when compared with vehicle treated rats. Acute oral toxicity profile of IVT-21 demonstrated that it is safe up to 2000 mg/kg body weight in experimental mice. This result suggests the suitability of IVT-21 for further study in the management of arthritis and related complications.

Abstract
Red wine is a well-known alcoholic beverage, and is known to have phenolic compounds (PCs), which contribute to its antioxidant activity and have other beneficial advantages for human health. The aim of this study was to evaluate the effect of the simulated gastro-intestinal digestion and the Caco-2 transepithelial transport assay on the PCs, bioavailability, and the antioxidant capacity of red wines. The contents of PCs in red wine were significantly reduced during most of the digestion phases. Phenolic acid had the greatest permeability, while the flavonols had the weakest. The bioavailability of PCs ranged from 2.08 to 24.01%. The result of the partial least squares structural equation model showed that the three phenols were positively correlated with the antioxidant activity of red wine. The contribution of anthocyanins was the largest (0.8667).

Macrophage-Targeted Punicalagin Nanoengineering to Alleviate Methotrexate-Induced Neutropenia: A Molecular Docking, DFT, and MD Simulation Analysis. MOLECULES (BASEL, SWITZERLAND) 2022; 27:molecules27186034.

Abstract
Punicalagin is the most bioactive pomegranate polyphenol with high antioxidant and free-radical scavenging activity and can potentially cure different ailments related to the cardiovascular system. The current research work was envisioned to predict the targeting efficiency of punicalagin (PG) nanoparticles to the macrophages, more specifically to bone marrow macrophages. For this, we selected mannose-decorated PLGA-punicalagin nanoparticles (Mn-PLGA-PG), and before formulating this nanocarrier in laboratory settings, we predicted the targeting efficiency of this nanocarrier by in silico analysis. The analysis proceeded with macrophage mannose receptors to be acquainted with the binding affinity and punicalagin-based nanocarrier interactions with this receptor. In silico docking studies of macrophage mannose receptors and punicalagin showed binding interactions on its surface. PG interacted with hydrogen bonds to the charged residue ASP668 and GLY666 and polar residue GLN760 of the Mn receptor. Mannose with a docking score of −5.811 Kcal/mol interacted with four hydrogen bonds and the mannose receptor of macrophage, and in PLGA, it showed a −4.334 Kcal/mol docking score. Further, the analysis proceeded with density functional theory analysis (DFT) and HOMO–LUMO analysis, followed by an extensive 100 ns molecular dynamics simulation to analyse the trajectories showing the slightest deviation and fluctuation. While analysing the ligand and protein interaction, a wonderful interaction was found among the atoms of the ligand and protein residues. This computational study confirms that this nanocarrier could be a promising lead molecule to regulate the incidence of drug-induced neutropenia. Furthermore, experimental validation is required before this can be stated with complete confidence or before human use.

Abstract
Rheumatoid arthritis (RA) is a chronic inflammatory and autoimmune disorder. RA is progressive and needs long-term treatment. Vitexin is a naturally-occurring flavonoid that is identified in various plant sources. Vitexin is demonstrated to produce antioxidant effects with numerous pharmacological activities. This experimental in vivo study assessed the antiarthritic and apoptotic role of a natural plant extract, vitexin, on RA. Collagen-induced arthritis (CIA) rat model Sprague Dawley males were grouped into five sets with six rats each: control, CIA, CIA + vitexin (10 mg/kg bw), CIA + Methotrexate (1 mg/kg bw), and vitexin (10 mg/kg bw) alone. The body weight, organ weight, biochemical assay, inflammatory enzymes, apoptosis, and cytokines levels were evaluated and compared among groups. Janus kinase (JAK)/signal transducer and activator of transcription (STAT)/suppressors of cytokine signaling (SOCS) levels and histopathology of ankle joints were also studied and compared. Significance was considered at a p < 0.05. Vitexin (10 mg/kg bw) significantly reduced the inflammatory enzyme markers, interleukin (IL)-1β, IL-6, IL-17, IL-4, IL-10, tumor necrosis factor-α, interferon-γ, and iNOS levels in arthritis rats (p < 0.05). Vitexin significantly improved collagen-induced arthritic histological changes (p < 0.05). Vitexin also reduced JAK/STAT expressions associated with inflammation and significantly increased elevated SOCS levels (p < 0.05). Aberration in apoptosis, inflammatory mediators, C-reactive protein, and rheumatoid factor levels in the arthritic rats reverted to normal with vitexin. These results emphasize that vitexin possesses anti-inflammatory and apoptotic activity via the regulation of JAK/STAT/SOCS signaling in CIA in a rat model. Hence, vitexin is a promising auxiliary drug for RA treatment.

Concerted regulation of OPG/RANKL/ NF‑κB/MMP-13 trajectories contribute to ameliorative capability of prodigiosin and/or low dose γ-radiation against adjuvant- induced arthritis in rats. Int Immunopharmacol 2022; 111:109068. [PMID: 35944459 DOI: 10.1016/j.intimp.2022.109068] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2022] [Revised: 07/08/2022] [Accepted: 07/14/2022] [Indexed: 11/22/2022]
Abstract
BACKGROUND Prodigiosin (PDG) is a microbial red dye with antioxidant and anti-inflammatory properties, although its effect on rheumatoid arthritis (RA) remains uncertain. Also, multiple doses of low dose γ- radiation (LDR) have been observed to be as a successful intervention for RA. Thus, the purpose of this study was to investigate the ameliorative potential of PDG and/or LDR on adjuvant-induced arthritis (AIA) in rats. METHODS The anti-inflammatory and anti-arthritic effects of PDG and/or LDR were examined in vitro and in vivo, respectively. In the AIA model, the arthritic indexes, paw swelling degrees, body weight gain, and histopathological assessment in AIA rats were assayed. The impact of PDG (200 µg/kg; p.o) and/or LDR (0.5 Gy) on the levels of pro- and anti-inflammatory cytokines (IL-1β, TNF-α, IL-6, IL-18, IL-17A, and IL-10) as well as the regulation of osteoprotegrin (OPG)/ receptor activator of nuclear factor κB ligand (RANKL)/ nuclear factor-κB (NF-κB)/MMP-13 pathways was determined. Methotrexate (MTX; 0.05 mg/kg; twice/week, i.p) was administered concurrently as a standard anti-arthritic drug. RESULTS PDG and/or LDR markedly diminished the arthritic indexes, paw edema, weigh loss in AIA rats, alleviated the pathological alterations in joints, reduced the levels of pro-inflammatory cytokines IL-1β, TNF-α, IL-6, IL-18, IL-17A, and RANKL in serum and synovial tissues, while increasing anti-inflammatory cytokines IL-10 and OPG levels. Moreover, PDG and/or LDR down-regulated the expression of RANKL, NF-κBp65, MMP13, caspase-3, and decreased the RANKL/OPG ratio, whereas OPG and collagen II were enhanced in synovial tissues. CONCLUSION PDG and/or LDR exhibited obvious anti-RA activity on AIA.

Abstract
Background Rheumatoid arthritis (RA) is a chronic, systemic inflammatory, and debilitating autoimmune illness. The objective of the present study was to evaluate the relationship between animal flesh foods consumption and rheumatoid arthritis. Methods Meat consumption was assessed by using a semi-quantitative Food Frequency Questionnaire (168 items) in a case-control study of 297 subjects (100 newly diagnosed cases and 197 healthy controls). An expert rheumatologist diagnosed patients based on the American College of Rheumatology definitions, 2010. Multivariate logistic regression, adjusted for lifestyle and nutritional confounders, was used to evaluate the relationship between dairy consumption and rheumatoid arthritis. Results Participants with greater consumption of fish and seafood were less likely to have RA (OR 0.52; 95% CI 0.27–0.98). Conversely, a higher processed meat intake was associated with increased odds of RA (OR 3.45; 95% CI 1.78–6.68). However, no significant association was found between red meats and poultry consumption and the risk of RA in the fully adjusted model. Conclusions The present study suggests an inverse association between fish and seafood consumption and the risk of RA. On the contrary, a higher amount of processed meat intake was associated with increased odds of RA. However, further studies are warranted to confirm the veracity of our findings.

Abstract
Coronopus didymus (L.) Sm. (CD) has been traditionally used to treat pain, rheumatism, and inflammation. This study was planned to appraise the anti-oxidant, anti-inflammatory and anti-arthritic potentials of CD (whole plant) aqueous ethanolic (CDAEE) and aqueous extracts (CDAE) and chemical characterization by high-performance liquid chromatography-diode array detector. In vivo anti-inflammatory (Carrageenan induced paw edema, and Xylene induced ear edema assays) and anti-arthritic potentials were evaluated in Wistar rats. Both extracts showed significant (p < 0.0001) in vitro free radical scavenging and in vitro anti-arthritic potentials by inhibition of protein denaturation and stabilization of the HRBC membrane and anti-oedematogenic potential, whereas more activity was expressed by CDAEE. In complete Freund's adjuvant-induced arthritic model, the CDAEE at 200, 400, and 800 mg kg-1 and methotrexate (1 mg kg-1) profoundly (p < 0.05) reduced the arthritic score and paw edema, restored body and immune organ weight, and altered blood parameters and oxidative stress biomarkers. The qRT-PCR analysis revealed that CDAEE at 400 mg kg-1 significantly (p < 0.0001) downregulated TNF-α (2.22 ± 0.16 fold), IL-6 (2.29 ± 0.05 fold), IL-1β (2.10 ± 0.01 fold), COX-2 (2.45 ± 0.02 fold), and NF-ĸβ (2.72 ± 0.06 fold) and considerably upregulated IL-10 (58.84 ± 0.67%), IL-4 (76.16 ± 2.79%) and I-kβ (75.45 ± 0.17%) in arthritic rats in contrast to disease control and methotrexate as evidenced from the joint histology. These findings suggested the antioxidant, anti-inflammatory and anti-arthritic activities of C. didymus, which might be due to the presence of quercetin, ferulic acid, dihydromyricetin, apigenin, vitexin, and kaempferol in CDAEE.

Abstract
Dietary polyphenols including phenolic acids, flavonoids, catechins, tannins, lignans, stilbenes, and anthocyanidins are widely found in grains, cereals, pulses, vegetables, spices, fruits, chocolates, and beverages like fruit juices, tea, coffee and wine. In recent years, dietary polyphenols have gained significant interest among researchers due to their potential chemopreventive/protective functions in the maintenance of human health and diseases. It is believed that dietary polyphenols/flavonoids exert powerful antioxidant action for protection against reactive oxygen species (ROS)/cellular oxidative stress (OS) towards the prevention of OS-related pathological conditions or diseases. Pre-clinical and clinical evidence strongly suggest that long term consumption of diets rich in polyphenols offer protection against the development of various chronic diseases such as neurodegenerative diseases, cardiovascular diseases (CVDs), cancer, diabetes, inflammatory disorders and infectious illness. Increased intake of foods containing polyphenols (for example, quercetin, epigallocatechin-3-gallate, resveratrol, cyanidin etc.) has been claimed to reduce the extent of a majority of chronic oxidative cellular damage, DNA damage, tissue inflammations, viral/bacterial infections, and neurodegenerative diseases. It has been suggested that the antioxidant activity of dietary polyphenols plays a pivotal role in the prevention of OS-induced human diseases. In this narrative review, the biological/pharmacological significance of dietary polyphenols in the prevention of and/or protection against OS-induced major human diseases such as cancers, neurodegenerative diseases, CVDs, diabetes mellitus, cancer, inflammatory disorders and infectious diseases have been delineated. This review specifically focuses a current understanding on the dietary sources of polyphenols and their protective effects including mechanisms of action against various major human diseases.

Abstract
Tea polyphenols have been extensively studied for their preventive properties against cardiometabolic diseases. Nevertheless, the evidence of these effects from human intervention studies is not always consistent, mainly because of a large interindividual variability. The bioavailability of tea polyphenols is low, and metabolism of tea polyphenols highly depends on individual gut microbiota. The accompanying reciprocal relationship between tea polyphenols and gut microbiota may result in alterations in the cardiometabolic effects, however, the underlying mechanism of which is little explored. This review summarizes tea polyphenols-microbiota interaction and its contribution to interindividual variability in cardiometabolic effects. Currently, only a few bacteria that can biodegrade tea polyphenols have been identified and generated metabolites and their bioactivities in metabolic pathways are not fully elucidated. A deeper understanding of the role of complex interaction necessitates fully individualized data, the ntegration of multiple-omics platforms and development of polyphenol-centered databases. Knowledge of this microbial contribution will enable the functional stratification of individuals in the gut microbiota profile (metabotypes) to clarify interindividual variability in the health effects of tea polyphenols. This could be used to predict individual responses to tea polyphenols consumption, hence bringing us closer to personalized nutrition with optimal dose and additional supplementation of specific microorganisms.

[PMID: 33922896 PMCID: PMC8146333 DOI: 10.3390/nu13051452] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Revised: 04/12/2021] [Accepted: 04/22/2021] [Indexed: 11/19/2022] Open
Abstract
Why measure and leverage food motives and values? Every failure and every success in dietary change can be connected to motivation. Therefore, this research question naturally arises: How can food motives and values be measured and leveraged to improve diet outcomes from the individual to populations? There are four ways that food motives and values (FMVs) can assist researchers and health professionals. First, FMVs can help to create a personalized approach to dietary change. Second, FMVs can inform content for dietary interventions. Third, these FMV measures can be used in data analysis to elucidate differences in adherence and outcomes among participants. Fourth, public health nutrition messages can be tailored using information on FMVs. Each of these uses has the potential to further the literature and inform future efforts to improve diet. A central aim of our study is to provide specific examples and recommendations on how to measure and leverage FMVs. To do so, we reviewed 12 measures included in the literature citing the Food Choice Questionnaire by Steptoe, Pollard, and Wardle, which was identified as the earliest, highly cited article appearing under the search terms “food motives” AND “food values” AND “eating behavior” AND “measure”. Specific details on how articles were selected from the citing literature are described in the Methods section. We also expound on our reasoning for including the Three-Factor Eating Questionnaire, which made for 13 measures in total. Our main finding is that each measure has strengths and shortcomings to consider in using FMVs to inform nutritional recommendations at different levels.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ershiwuwei Lvxue Pill (ELP, མགྲིན་མཚལ་ཉེར་ལྔ།), a traditional Tibetan medicine preparation, has been used hundreds of years for the clinical treatment of rheumatoid arthritis (RA) in the highland region of Tibet, China. However, the underlying mechanism of its therapeutic effect remains unclear. AIM OF THE STUDY The present study aimed to investigate the potential pharmacological mechanisms of anti-arthritic effect of ELP. MATERIALS AND METHODS The main chemical constituents of ELP were analyzed by ultra-performance liquid chromatography quadrupole-time-flight mass spectrometry (UPLC-Q-TOF-MS). Forty-eight male Wistar rats (220 ± 20 g) were randomly divided into six groups: normal group, collagen-induced arthritis (CIA) group, methotrexate group (1.05 mg/kg), ELP groups (115, 230 and 460 mg/kg). CIA rat models were assigned to evaluate the anti-RA activity of ELP by determining the paws swelling, arthritis score, organ coefficients of spleen and thymus, and histopathological analysis of knee joints of synovial tissues. The levels of TNF-α, IL-10, IL-6 and IL-17 in serum were measured by ELISA. In addition, mRNA and protein expression levels associated with JAK2/STAT3 signaling pathway in synovial tissues of CIA rats were detected by qRT-PCR, immunohistochemistry and Western blot analyses. RESULTS Fourteen main chemical constituents of ELP were quantitatively determined by UPLC-Q-TOF-MS analysis. Treatment with ELP reduced the paw swelling, arthritis score and organ coefficients of spleen and thymus. Histopathological examination revealed the protective effects of ELP on CIA rats with knee joint injury. The levels of serum pro-inflammatory cytokines (TNF-α, IL-6 and IL-17) were markedly reduced while the anti-inflammatory cytokine IL-10 was significantly increased with the treatment of ELP. Further investigations showed ELP down-regulated the mRNA and protein expression levels of Bcl-2, whereas up-regulated Bax, SOCS1 and SOCS3. Meanwhile, the ratios of p-JAK2/JAK2 and p-STAT3/STAT3 proteins from synovial tissues were dramatically decreased with the treatment of ELP, whereas no changes of the mRNA and protein expression levels of JAK2 and STAT3 were observed. CONCLUSION These results indicated that ELP reduced the severity of arthritis and joint swelling, suggesting an antirheumatic effect on CIA rats. The possible mechanism is related to inhibiting inflammatory response and inducing apoptosis in synovial tissues by regulating JAK2/STAT3 signaling pathway. However, further in vivo and in vitro investigations are still needed to clarify the underlying mechanism of ELP in treating RA.

Abstract
BACKGROUND Rheumatoid arthritis (RA) is associated with joint damage. For treatment, non-steroidal anti-inflammatory drugs (NSAIDs), steroidal agents, and immune-suppressants are used. Their side-effects require a safe and effective natural alternative. ANIMALS AND METHODS Thirty-six male albino rats, half kept under observation for 1 week (group I) and others for 2 weeks (group II) were used. Each group was subdivided into: normal (A), RA (B), and oral mandarin-peel extract (MPE) treated (C). Ankle diameter, serum levels of RF, interleukin (IL)-1β, TNFα, IL-4, IL-10, liver homogenates malondialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD), and nitric oxide (NO) were measured together with the histopathological examination. RESULTS MPE treatment was associated with increased serum IL-4, IL-10, liver homogenates GSH, and SOD, and decreased ankle diameter, serum RF, IL-1β, TNFα, liver homogenates MDA, NO, inflammatory cell infiltrate, and necrosis. Two weeks' treatment was better. CONCLUSIONS MPE has useful effects in alleviating the disturbed ankle diameter, serum pro- and anti-inflammatory mediators, oxidative stress, and ankle joint histopathology in rheumatic rats.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Rhamnella gilgitica Mansf. et Melch. (སེང་ལྡེང་།, RG) is a traditional Tibetan medicinal plant that is currently grown throughout Tibet. According to the theory of Tibetan medicine, RG is efficient for removing rheumatism, reducing swelling, and relieving pain. Hence, it has been used for the treatment of rheumatoid arthritis (RA) in Tibet for many years. However, there are no previous reports on the anti-RA activities of ethyl acetate extract of RG (RGEA). AIM OF THE STUDY This study aimed to explore the anti-RA effect and mechanism of RGEA on collagen-induced arthritis (CIA) in rats. MATERIALS AND METHODS The CIA model was established in male Wister rats by intradermal injection of bovine type II collagen and Complete Freund's Adjuvant at the base of the tail and left sole, respectively. The rats were orally administered with RGEA (9.71, 19.43, or 38.85 mg/kg) for 23 days. The body weight, swelling volume, arthritis index score, thymus and spleen indices, and pathological changes were observed to evaluate the effect of RGEA on RA. Furthermore, the inflammatory cytokines in serum, such as interleukin1 beta (IL-1β), tumor necrosis factor alpha (TNF-α), interleukin6 (IL-6), interleukin17 (IL-17), interferon-γ (INF-γ), interleukin4 (IL-4), and interleukin10 (IL-10) were measured by enzyme linked immunosorbent assay (ELISA) to explore the anti-inflammatory effects of RGEA. The terminal deoxynucleotidyl transferase dUTP nick-end labelling (TUNEL) staining was used to examine apoptosis. Finally, the protein and gene expression of B-cell lymphoma-2-associated X (Bax), B-cell lymphoma 2 (Bcl-2), Caspase3, janus-activated kinase 2 (JAK2), signal transducer and activator of transcription 3 (STAT3), suppressor of cytokine signaling1 (SOCS1), and 3 (SOCS3) in synovial tissue were detected using immunohistochemistry and real-time quantitative polymerase chain reaction (RT-qPCR). RESULTS After the treatment with RGEA, the body weight of rats was restored, both the arthritis index and paw swelling were suppressed, and spleen and thymus indices were decreased. RGEA reduced the inflammatory cells and synovial hyperplasia in the synovial tissue of the knee joint, and suppressed bone erosion. Meanwhile, RGEA decreased the levels of IL-1β, IL-6, IL-17, TNF-α, and INF-γ, while increased the levels of IL-4 and IL-10. TUNEL fluorescence apoptosis results confirmed that RGEA obviously promoted the apoptosis of synovial cells. Further studies showed that RGEA inhibited the proteins and mRNAs expression of JAK2 and STAT3 as well as increased the proteins and mRNAs expression of SOCS1 and SOCS3. In addition, RGEA upregulated the expression of Bax and Caspase3, and downregulated the expression of Bcl-2. CONCLUSION The anti-RA effectof RGEA might be related to the promotion of apoptosis and inhibition of inflammation, which regulated the JAK-STAT pathway.

Abstract
Consumers increasingly prefer and seek food and beverages, which, due to their natural characteristics, bring health benefits, both in the prevention of diseases and in their curative power. In this way, the production of nutraceutical foods and beverages gains more and more importance in the market. On the other hand, and because the eyes also eat, producing attractive foods due to their color, texture, appearance, and sensory characteristics is a permanent challenge in the food industry. Being able to gather healthy and attractive items in a single food is an even greater challenge. The long list of benefits associated with phenolic compounds, such as antioxidant, anticancer, anti-inflammatory, and antiaging properties, among others, fully justifies their use in the enrichment of various food products. Thus, in this review, we propose to summarize the potential use of phenolic compounds used as ingredients of pleasant and functional beverages.

A New Peracetylated Oleuropein Derivative Ameliorates Joint Inflammation and Destruction in a Murine Collagen-Induced Arthritis Model via Activation of the Nrf-2/Ho-1 Antioxidant Pathway and Suppression of MAPKs and NF-κB Activation. Nutrients 2021; 13:nu13020311.

Abstract
Oleuropein (OL), an olive tree secoiridoid and its peracetylated derivate (Per-OL) have exhibited several beneficial effects on LPS-stimulated macrophages and murine experimental systemic lupus erythematosus (SLE). This study was designed to evaluate dietary Per-OL in comparison with OL supplementation effects on collagen-induced arthritis (CIA) murine model. Three-weeks-old DBA-1/J male mice were fed from weaning with a standard commercial diet or experimental enriched-diets in 0.05 % (w/w) OL, 0.05% and 0.025% Per-OL. After six weeks of pre-treatment, arthritis was induced by bovine collagen type II by tail base injection (day 0) and on day 21, mice received a booster injection. Mice were sacrificed 42 days after the first immunization. Both Per-OL and OL diets significantly prevented histological damage and arthritic score development, although no statistically significant differences were observed between both compounds. Also, serum collagen oligomeric matrix protein (COMP), metalloprotease (MMP)-3 and pro-inflammatory cytokines levels were ameliorated in paws from secoiridoids fed animals. Mitogen-activated protein kinases (MAPK)s and nuclear transcription factor-kappa-B (NF-κB) activations were drastically down-regulated whereas nuclear factor E2-related factor 2 (Nrf2) and heme-oxygenase-1 (HO-1) protein expressions were up-regulated in those mice fed with OL and Per-OL diets. We conclude that both Per-OL and its parent compound, OL, supplements might provide a basis for developing a new dietary strategy for the prevention of rheumatoid arthritis.

Abstract
Rheumatoid arthritis (RA) is a chronic, systemic, inflammatory autoimmune disease that affects about 1% of the global population, with a female–male ratio of 3:1. RA preferably affects the joints, with consequent joint swelling and deformities followed by ankylosis. However, evidence has accumulated showing that patients suffering from RA can also develop extra-articular manifestations, including cardiovascular disease states, neuropathies, and multiorgan dysfunction. In particular, peripheral nerve disorders showed a consistent impact in the course of the disease (prevalence about 20%) mostly associated to vasculitis of the nerve vessels leading to vascular ischemia, axonal degeneration, and neuronal demyelination. The pathophysiological basis of this RA-associated microvascular disease, which leads to impairment of assonal functionality, is still to be better clarified. However, endothelial dysfunction and alterations of the so-called brain-nerve barrier (BNB) seem to play a fundamental role. This review aims to assess the potential mechanisms underlying the impairment of endothelial cell functionality in the development of RA and to identify the role of dysfunctional endothelium as a causative mechanism of extra-articular manifestation of RA. On the other hand, the potential impact of lifestyle and nutritional interventions targeting the maintenance of endothelial cell integrity in patients with RA will be discussed as a potential option when approaching therapeutic solutions in the course of the disease.

Abstract
BACKGROUND This study sought to assess the effect of hesperidin on serum inflammatory cytokines and oxidative damage in liver of complete Freund's adjuvant (CFA)-induced arthritic rats. METHOD Fifty-six adult female Wistar rats (220-250 g) were acclimatized for two weeks. Intraplantar injection of CFA was done for the induction of arthritis and confirmed on the 14th day prior to oral administration of 40 and 80 mg/kg of hesperidin or dexamethasone for 45 days. RESULT The result showed that treatment with both doses of hesperidin and dexamethasone in the joint of arthritic rats significantly (p < .05) diminished paw swelling/edema and arthritis score as well as enhanced latency in thermal hyperalgesia test. In addition, hesperidin treatment in arthritis rats showed significant (p < .01) improvement in red blood cells and platelets counts as well as hemoglobin and hematocrit compared to the arthritis control rat group. Furthermore, hesperidin treatment significantly (p < .05) reduced serum interferon gamma (IFN-γ) and interleukin-4 (IL-4) levels in arthritic rat. In addition, treatment with hesperidin significantly (p < .05) decreased the liver of thiobarbituric acid reactive species and reactive oxygen species levels but raised the levels of total and non-protein thiols of rat induced with CFA. The reduced activities of liver δ-aminolevulinate dehydratase, catalase, glutathione-S transferase in arthritic rats were significantly (p < .05) increased with hesperidin treatment in arthritic rats. This study suggests that hesperidin demonstrated an anti-arthritic effect via modulation of serum IFN-γ and IL-4 levels as well as protection against oxidative damage. CONCLUSION Hence, hesperidin could be a potential immune-modulatory, anti-inflammatory and anti-oxidant agent.

Abstract
Pain is one of the main problems for modern society and medicine, being the most common symptom described by almost all patients. When pain becomes chronic, the life of the patients is dramatically affected, being associated with significant emotional distress and/or functional disability. A complex biopsychosocial evaluation is necessary to better understand chronic pain, where good results can be obtained through interconnected biological, psychological, and social factors. The aim of this study was to find the most relevant articles existent in the PubMed database, one of the most comprehensive databases for medical literature, comprising dietary patterns to alleviate chronic pain. Through a combined search using the keywords "chronic pain" and "diet" limited to the last 10 years we obtained 272 results containing the types of diets used for chronic pain published in the PubMed database. Besides classical and alternative methods of treatment described in literature, it was observed that different diets are also a valid solution, due to many components with antioxidant and anti-inflammatory qualities capable to influence chronic pain and to improve the quality of life. Thirty-eight clinical studies and randomized controlled trials are analyzed, in an attempt to characterize present-day dietary patterns and interventions to alleviate chronic pain.

Abstract
This chapter introduces some types of animal models which are used for better understanding the disease mechanisms and its treatment. These experimental models fall into two categories: spontaneous models and induced models. Among the diseases, rheumatoid arthritis (RA) as an autoimmune disease was considered. To study the pathogenesis of RA, we explained collagen-induced arthritis as an animal model that reflects a characteristic feature of RA patients. In addition, experimental allergic encephalomyelitis (EAE) as an experimental model for multiple sclerosis (MS) was explained in detail to represent a standard method to investigate in its mechanism, finding the way for the amelioration of this incurable neurological disorder.

Abstract
The Mediterranean diet is considered as the foremost dietary regimen and its adoption is associated with the prevention of degenerative diseases and an extended longevity. The preeminent features of the Mediterranean diet have been agreed upon and the consumption of olive oil stands out as the most peculiar one. Indeed, the use of olive oil as the nearly exclusive dietary fat is what mostly characterizes the Mediterranean area. Plenty of epidemiological studies have correlated that the consumption of olive oil was associated with better overall health. Indeed, extra virgin olive oil contains (poly)phenolic compounds that are being actively investigated for their purported biological and pharma-nutritional properties. On 18 and 19 May 2018, several experts convened in Jaen (Spain) to discuss the most recent research on the benefits of olive oil and its components. We reported a summary of that meeting (reviewing several topics related to olive oil, not limited to health) and concluded that substantial evidence is accruing to support the widespread opinion that extra virgin olive oil should, indeed, be the fat of choice when it comes to human health and sustainable agronomy.

Abstract
Glioma is one of the most perplexing cancers because of its infiltrating nature, molecular signaling, and location in central nervous system. Blood-brain barrier acts as a natural barrier to the glioma making it difficult to access by conventional chemotherapy. Clinicians are using natural compounds or their derivatives for several diseases including different cancers. However, the feasibility of using natural compounds in glioma is not explored in details. Natural compounds can act over a wide variety of signaling pathways such as survival and metabolic pathways and induce cell death. Some of the natural agents have additional benefits of crossing biological barriers such as blood-brain barrier with ease having few or no impact on the surrounding healthy cells. All of these benefits make natural compounds a prospective candidate for the glioma management. This article evaluates the benefits of using natural compounds for glioma therapy and their possible mechanism of actions. We have discussed the natural compounds assessed currently for glioma therapy and proposed a few novel natural compounds with potential antiglioma effect based on their mechanism of action.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The whole plant of Glycine tabacina (Labill.) Benth has been used as a traditional herbal medicine to treat rheumatism, ostealgia and nephritis in China. It is also one of the sources of the renowned native herbal medicine 'I-Tiao-Gung' in Taiwan. AIM OF THE STUDY This study aimed to investigate the anti-arthritic effect of ethanol extract of G. tabacina (GTE) in a collagen-induced arthritis (CIA) rat model. MATERIALS AND METHODS The chemical profile of GTE was analyzed by HPLC-UV. The CIA was induced in male Wistar rats by intradermal injection of bovine type II collagen at tail root, back and ankle joints. The rats were orally administrated daily with GTE (1.11, 2.22 and 4.44 g dry weight of herb powder per kg body weight) from day 0 and continued for 30 days. Swelling volume and thickness of paw, arthritis index, X-radiographs and histopathological changes were examined to assess the severity of arthritis. Furthermore, the levels of pro-inflammatory cytokines, such as interleukin1β (IL-1β), IL-6 and tumor necrosis factor α (TNF-α), total superoxide dismutase (T-SOD) activity and malonaldehyde (MDA) level were measured to preliminarily explore the possible mechanisms. RESULTS Oral administration of GTE significantly ameliorated the arthritic symptoms in CIA rat model, as indicated by the effects on paws swelling and arthritis index. X-radiographic analysis and histopathological examinations demonstrated that GTE effectively protected the bone and cartilage of joints from erosion, lesion and deformation. The efficacy of GTE treatment on CIA was comparable to that of indomethacin (positive drug). Besides, the overproduction of IL-1β, IL-6 and TNF-α was remarkably inhibited in the serum of all GTE treatment groups. The restoration of serum T-SOD activity and MDA level proved that GTE administration alleviated the oxidative stress in CIA rats. CONCLUSIONS GTE exhibited strong anti-CIA activity through inhibiting pro-inflammatory cytokines and oxidation in rats, suggesting its potential preventive and therapeutic effects on rheumatoid arthritis (RA).

Abstract
The polyphenolic extract (PE) from extra virgin olive oil (EVOO) has been shown to possess important anti-inflammatory and joint protective properties in murine models of rheumatoid arthritis (RA). This study was designed to evaluate the effects of PE on IL-1β-activated human synovial fibroblasts SW982 cell line. PE from EVOO treatment inhibited IL-1β-induced matrix metalloproteases (P<0·001), TNF-α and IL-6 production (P<0·001). Similarly, IL-1β-induced cyclo-oxygenase-2 and microsomal PGE synthase-1 up-regulations were down-regulated by PE (P<0·001). Moreover, IL-1β-induced mitogen-activated protein kinase (MAPK) phosphorylation and NF-κB activation were ameliorated by PE (P<0·001). These results suggest that PE from EVOO reduces the production of proinflammatory mediators in human synovial fibroblasts; particularly, these protective effects could be related to the inhibition of MAPK and NF-κB signalling pathways. Taken together, PE from EVOO probably could provide an attractive complement in management of diseases associated with over-activation of synovial fibroblasts, such as RA.

Abstract
Ulcerative colitis is an idiopathic inflammatory bowel disease characterized by intestinal inflammation; blocking this inflammatory process may be the key to the development of new naturally occurring anti-inflammatory drugs, with greater efficiency and lower side effects. The objective of this study is to explore the effects of bergenin (BG) in TNBS (2,4,6-trinitrobenzenesulfonic acid)-induced acute colitis model in rats in order to assist in the studies for the development of novel natural product therapies for inflammatory bowel disease. 48 Wistar rats were randomized into six groups: (i) Control and (ii) TNBS control; (iii) 5-ASA 100 mg/kg/day (iv) BG 12 mg/kg/day (v) BG 25 mg/kg/day and (vi) BG 50 mg/kg/day. Colitis was induced by instillation of TNBS. Colitis was evaluated by an independent observer who was blinded to the treatment. Our results revealed that bergenin decreased the macroscopic and microscopic damage signs of colitis, and reduced the degree of neutrophilic infiltration in the colon tissue; also, it was capable to down-regulate COX-2, iNOS, IkB-α, and pSTAT3 protein expression. Similarly, using a protocol for indirect ELISA quantification of cytokines, bergenin treatment reduced IL-1β, IFN-γ and IL-10 levels, and inhibited both canonical (IL-1) and non-canonical (IL-11) NLRP3/ASC inflammasome signaling pathways in TNBS-induced acute colitis. Conclusion: Our study has provided evidence that administration of bergenin reduced the damage caused by TNBS in an experimental model of acute colitis in rats, reduced levels of pro-inflammatory proteins and cytokines probably by modulation of pSTAT3 and NF-κB signaling and blocking canonical and non-canonical NLRP3/ASC inflammasome pathways.

Abstract
Rheumatoid arthritis (RA) is a systemic chronic inflammatory disease associated with a potential imbalance between the growth and death of rheumatoid arthritis fibroblast-like synoviocytes (RA-FLSs). Imperatorin (IPT) is a naturally occurring furanocoumarin found in umbelliferous vegetables, citrus fruits, and some herbs. The effects of IPT on the proliferation and apoptosis of RA-FLSs and its potential underlying mechanisms have remained unclear. RA-FLSs obtained from RA patients were induced by interleukin-1β (IL-1β) and treated with IPT. Cell viability was determined by MTT assay. Apoptotic cell death was analyzed by Annexin V-FITC/PI double staining and Hoechst 33342 staining. The loss in the mitochondrial membrane potential (ΔΨm) was visualized on the basis of JC-1 staining via fluorescence microscopy, and protein expression changes were assessed by western blot, whereas in vivo studies were conducted in male Wistar rats followed by histopathological assessment via TUNEL assay and HE staining of tissues. The results showed that IPT significantly reduced cell viability, accelerated cell apoptosis and decreased matrix metalloproteinases-1/-3 expression in IL-1β-induced RA-FLSs. Furthermore, IPT exposure was found to disrupt the ΔΨm compared to the IL-1β-induced treatment. Moreover, IPT increased the release of mitochondrial cytochrome C, the ratio of Bax/Bcl-2, and the cleavage of caspase-9, caspase-3 and poly (ADP-ribose) polymerase. In vivo studies showed that IPT not only significantly reduced the collagen induced arthritis by reducing synovial hyperplasia, and pannus formation but also enhanced the apoptotic index of ankle joint cells. Conclusively, our findings suggest that IPT inhibits cell proliferation and induces apoptosis in RA-FLSs that may be associated with mitochondrial/caspase-mediated signalling pathways.

Abstract
Nowadays, it is clear that an unhealthy diet is one of the prime factors that contributes to the rise of inflammatory diseases and autoimmunity in the populations of both developed and developing countries. The Mediterranean diet has been associated with a reduced incidence of certain pathologies related to chronic inflammation and the immune system. Olive oil, the principal source of dietary lipids of the Mediterranean diet, possesses a high nutritional quality and a particular composition, which is especially relevant in the case of Extra Virgin Olive Oil (EVOO). EVOO is obtained from olives solely by mechanical or other physical preparation methods, under conditions that do not alter the natural composition. EVOO is described as a key bioactive food with multiple beneficial properties and it may be effective in the management of some immune-inflammatory diseases. In this review, the key research is summarised which provides evidence of the beneficial effects of EVOO and its minor components focusing on their mechanisms on immune-inflammatory diseases such as rheumatoid arthritis, systemic lupus erythematosus, inflammatory bowel disease and sclerosis.

Abstract
OBJECTIVES GuiZhi-ShaoYao-ZhiMu decoction (GSZD), a traditional Chinese herbal medication for the management of rheumatoid arthritis (RA), has a long history of use and modern scientific research support for efficacy, but the studies have not been systematically evaluated. Therefore, this study systematically reviewed the efficacy of GSZD using the available human clinical trials and conducted a meta-analysis. METHODS The available databases were searched using proper languages of English, Korean, and Chinese. The key erms used for searching were "GSZD," "Cassia Twig," "Guizhi," "Paeonia lactiflora," "Shaoyao," "Anemarrhena Rhizome," "Zhimu," "rheumatoid arthritis," "randomized," "controlled trial," and "clinical trial." Randomized clinical trials (RCTs) using GSZD were included in the review and meta-analysis. According to heterogeneity, odds ratio and confidence intervals in the pooled RCTs were assessed by a fixed or random model in meta-analysis. Risk of bias was evaluated for all included studies. RESULTS Thirteen RCTs met the inclusion criteria and were included in the meta-analysis. All studies evaluated the efficacy of GSZD for treating RA, but the herbal formulations varied since some studies added herbs to the basic GSZD formulation. However, all formulations contained the essential herbs: Guizhi, Shaoyao, and Zhimu. Each RCT included an experimental group (GSZD with or without Western-style medicine) and a control group (either standard Western-style medicines or placebo). When compared to placebo, the GSZD treatment was found to be three to six times more effective than standard Western drugs for some symptoms. Furthermore, only two studies reported any adverse events associated with the GSZD group, whereas several reported serious adverse events in the control groups. CONCLUSIONS The Traditional Chinese Medicine, GSZD, may have equal or superior effectiveness and safety for treating RA compared to Western RA drugs. It should be considered a viable alternative to Western medicine. However, more long-term research is needed in larger patient groups to better establish its safety and efficacy.
