Efficacy and safety of dietary polyphenols in rheumatoid arthritis: A systematic review and meta-analysis of 47 randomized controlled trials.
To evaluate safety and efficacy of dietary polyphenols in the treatment of rheumatoid arthritis (RA).. CNKI, Pubmed, Cochrane library, Embase were searched to collect randomized controlled trials (RCTs) of dietary polyphenols in the treatment of RA. The databases were searched from the time of their establishment to November 8nd, 2022. After 2 reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies, Meta-analysis was performed using RevMan5.4 software.. A total of 49 records (47 RCTs) were finally included, involving 3852 participants and 15 types of dietary polyphenols (Cinnamon extract, Cranberry extract, Crocus sativus L. extract, Curcumin, Garlic extract, Ginger extract, Hesperidin, Olive oil, Pomegranate extract, Puerarin, Quercetin, Resveratrol, Sesamin, Tea polyphenols, Total glucosides of paeony). Pomegranate extract, Resveratrol, Garlic extract, Puerarin, Hesperidin, Ginger extract, Cinnamon extract, Sesamin only involve in 1 RCT. Cranberry extract, Crocus sativus L. extract, Olive oil, Quercetin, Tea polyphenols involve in 2 RCTs. Total glucosides of paeony and Curcumin involve in more than 3 RCTs. These RCTs showed that these dietary polyphenols could improve disease activity score for 28 joints (DAS28), inflammation levels or oxidative stress levels in RA. The addition of dietary polyphenols did not increase adverse events.. Dietary polyphenols may improve DAS28, reduce C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), and improve oxidative stress, etc. However, more RCTs are needed to verify or modify the efficacy and safety of dietary polyphenols.. https://www.crd.york.ac.uk/prospero/, identifier CRD42022315645.

Epidemic modeling has been a key tool for understanding the impact of global viral outbreaks for over two decades. Recent developments of the COVID-19 pandemic have accelerated research using compartmental models, like SI, SIR, SEIR, with their appropriate modifications. However, there is a large body of recent research consolidated on homogeneous population mixing models, which are known to offer reduced tractability, and render conclusions hard to quantify. As such, based on our recent work, introducing the heterogeneous geo-spatial mobility population model (GPM), we adapt a modified SIR-V (susceptible-infected-recovered-vaccinated) epidemic model which embodies the idea of patient relapse from R back to S, vaccination of R and S patients (reducing their infectiousness), thus altering the infectiousness of V patients (from Topics: Acute Lung Injury; Adherens Junctions; Animals; Anti-Bacterial Agents; Anti-Inflammatory Agents; Antigens, CD; Antineoplastic Agents, Phytogenic; Antioxidants; Apoptosis; beta Catenin; Brain Ischemia; Cadherins; Carcinogenesis; Catalysis; Cell Line; Cells, Cultured; Curcuma; Curcumin; Dioxoles; Disease Models, Animal; Endothelial Cells; Epithelial Cells; Heme Oxygenase (Decyclizing); Humans; Inflammasomes; Intestinal Diseases; Intestinal Mucosa; Ischemic Stroke; Kidney Neoplasms; Lignans; Lung; Macrophages; Male; Mice; Mice, Inbred C57BL; Mice, Knockout; Microglia; NAD(P)H Dehydrogenase (Quinone); Nanostructures; NF-E2-Related Factor 2; NF-kappa B; NLR Family, Pyrin Domain-Containing 3 Protein; Oxidative Stress; Phosphatidylinositol 3-Kinases; Phytotherapy; Plant Extracts; Pneumonia; PPAR gamma; Proto-Oncogene Proteins c-akt; Pyroptosis; Rats; Rats, Sprague-Dawley; Rats, Wistar; Reperfusion Injury; Respiratory Distress Syndrome; Sepsis; Sesamum; Signal Transduction; Silybin; Silybum marianum; Silymarin; Sirtuin 3; Titanium; Transfection; Treatment Outcome; White Matter | 2021 |
Assessing the neuroprotective effect of antioxidant food factors by application of lipid-derived dopamine modification adducts.
Advances in understanding the neurodegenerative pathologies are creating new opportunities for the development of neuroprotective therapies, such as antioxidant food factors, lifestyle modification and drugs. However, the biomarker by which the effect of the agent on neurodegeneration is determined is limited. We here address hexanoyl dopamine (HED), one of novel dopamine adducts derived from brain polyunsaturated acid, referring to its in vitro formation, potent toxicity to SH-SY5Y cells, and application to assess the neuroprotective effect of antioxidative food factors. Dopamine is a neurotransmitter, and its deficiency is a characterized feature in Parkinson's disease (PD); thus, HED provides a new insight into the understanding of dopamine biology and pathophysiology of PD and a novel biomarker for the assessment of neuroprotective therapies. We have established an analytical system for the detection of HED and its toxicity to the neuroblstoma cell line, SH-SY5Y cells. Here, we discuss the characteristics of the system and its applications to investigate the neuroprotective effect of several antioxidants that originate from food.

Effects of dietary ingredients on function and expression of P-glycoprotein in human intestinal epithelial cells.
The present study was conducted to investigate the functional and transcriptional modulation of P-glycoprotein (MDR-1) by several dietary ingredients (piperine, capsaicin, daidzein, genistein, sesamin, curcumin, taurine) in vinblastine-resistant colon carcinoma LS-180 cells (LS-180V cells). The amount of rhodamine 123 accumulated in LS-180V cells was significantly increased by capsaicin, piperine and sesamin, whereas it was significantly reduced by daidzein and genistein which stimulated the efflux of rhodamine 123. These results suggest that the P-glycoprotein-mediated efflux is inhibited by piperine, capsaicin and sesamin and stimulated by daidzein and genistein. The concurrent addition of piperine and capsaicin seemed to inhibit synergistically the P-glycoprotein-mediated efflux. Pretreatment with sesamin for 48 h caused a significant increase in MDR1 mRNA expression without a significant effect on the expression of P-glycoprotein or accumulation of rhodamine 123. Similar pretreatment with other ingredients had little effect on the expression of MDR1 mRNA or P-glycoprotein, suggesting that they do not cause transcriptional modulation of P-glycoprotein. Piperine, genistein and curcumin have been suggested to stimulate P-glycoprotein-mediated efflux without increasing P-glycoprotein expression. In LS-180V cells, significant increases in mRNA levels of multi-drug resistance associated protein 1 (MRP1) or MRP3 were observed on pretreatment with capsaicin, daidzein, piperine and sesamin. In conclusion, our results suggest that P-glycoprotein-mediated efflux is significantly affected by dietary ingredients. Also, capsaicin, daidzein, piperine and sesamin increased significantly the mRNA expression of MRP1 or MRP3. Thus, the present study provides further evidence that repeated exposure to dietary ingredients can cause drug-food interactions by affecting the function and mRNA expression of intestinal transporters such as P-glycoprotein.

Suppression of ochratoxin biosynthesis by naturally occurring alkaloids.
The effects of four alkaloids on the biosynthesis of ochratoxin A (OTA), ochratoxin B (OTB) and citrinin were examined on four OTA-producing aspergilli: Aspergillus auricomus, A. sclerotiorum and two isolates of A. alliaceus. Piperine and piperlongumine, natural alkaloids of Piper longum, significantly inhibited OTA production at 0.001% (w/v) for all aspergilli examined. Piperine and piperlongumine affected the polyketide synthesis step of OTA production and inhibited production of citrinin. Curcumin, a constituent of tumeric, completely inhibited mycelial growth of A. alliaceus isolate 791 at 0.1% (w/v) and decreased OTA production by approximately 70% at 0.01% (w/v). Sesamin, a constituent of sesame oil, inhibited OTA and OTB production by 60 and 45%, respectively, at 0.1% (w/v), showing its effect was on chloroperoxidase and polyketide synthase activity. The potential advantage of these natural products to reduce ochratoxin contamination of agricultural commodities is discussed.

Effects of dietary phenolic compounds on tocopherol, cholesterol, and fatty acids in rats.
The effects of the phenolic compounds butylated hydroxytoluene (BHT), sesamin (S), curcumin (CU), and ferulic acid (FA) on plasma, liver, and lung concentrations of alpha- and gamma-tocopherols (T), on plasma and liver cholesterol, and on the fatty acid composition of liver lipids were studied in male Sprague-Dawley rats. Test compounds were given to rats ad libitum for 4 wk at 4 g/kg diet, in a diet low but adequate in vitamin E (36 mg/kg of gamma-T and 25 mg/kg of alpha-T) and containing 2 g/kg of cholesterol. BHT significantly reduced feed intake (P < 0.05) and body weight and increased feed conversion ratio; S and BHT caused a significant enlargement of the liver (P < 0.001), whereas CU and FA did not affect any of these parameters. The amount of liver lipids was significantly lowered by BHT (P < 0.01) while the other substances reduced liver lipid concentrations but not significantly. Regarding effects on tocopherol levels, (i) feeding of BHT resulted in a significant elevation (P< 0.001) of alpha-T in plasma, liver, and lung, while gamma-T values remained unchanged; (ii) rats provided with the S diet had substantially higher gamma-T levels (P < 0.001) in plasma, liver, and lung, whereas alpha-T levels were not affected; (iii) administration of CU raised the concentration of alpha-T in the lung (P < 0.01) but did not affect the plasma or liver values of any of the tocopherols; and (iv) FA had no effect on the levels of either homolog in the plasma, liver, or lung. The level of an unknown substance in the liver was significantly reduced by dietary BHT (P < 0.001). BHT was the only compound that tended to increase total cholesterol (TC) in plasma, due to an elevation of cholesterol in the very low density lipoprotein + low density lipoprotein (VLDL + LDL) fraction. S and FA tended to lower plasma total and VLDL + LDL cholesterol concentrations, but the effect for CU was statistically significant (P < 0.05). FA increased plasma high density lipoprotein cholesterol while the other compounds reduced it numerically, but not significantly. BHT, CU, and S reduced cholesterol levels in the liver TC (P < 0.001) and percentages of TC in liver lipids (P < 0.05). With regard to the fatty acid composition of liver lipids, S increased the n-6/n-3 and the 18:3/20:5 polyunsaturated fatty acids (PUFA) ratios, and BHT lowered total monounsaturated fatty acids and increased total PUFA (n-6 + n-3). The effects of CU and FA on fatty acids were not highly significant.

Effects of sesamin and curcumin on delta 5-desaturation and chain elongation of polyunsaturated fatty acid metabolism in primary cultured rat hepatocytes.
Effects of sesamin and curcumin on delta 5-desaturation and chain elongation of polyunsaturated fatty acid (PUFA) were studied in rat primary cultured hepatocytes. When sesamin was added to culture medium containing 20:4 (n-3), rat hepatocytes after 24 h of incubation produced 20:5 (n-3) from 20:4 (n-3), whereas when incubated with 20:3 (n-6), the metabolite by delta 5-desaturation did not accumulate, and consequently, the ratio of 20:3 (n-6)/20:4 (n-6) increased with the amount of sesamin added. Curcumin was more effective than sesamin in this respect. Both sesamin and curcumin interfered with chain elongation of PUFAs. An addition of 18:3 (n-6) or 18:4 (n-3) increased the cellular concentrations of 20:3 (n-6) or 20:4 (n-3), respectively, but the simultaneous addition of sesamin or curcumin inhibited the chain elongation of C18 acids (the fatty acids with 18 carbons) into corresponding C20 and C18 acids. Similarly, the elongation from C20 of n-3 and n-6 families to C22 was also inhibited with sesamin and curcumin. These results suggested that: 1) sesamin and curcumin inhibited delta 5-desaturation of n-6 fatty acid, but not n-3 fatty acid in rat hepatocytes; 2) curcumin was more effective than sesamin; 3) chain elongation was also inhibited by sesamin and curcumin.
