The mode of action of COVID-19 consists of three phases, i.e. viral replication, immune hyperactivity and pulmonary destruction. However, angiotensin-converting enzyme is an essential receptor that causes COVID-19. After infecting any individual, COVID-19 develops in specific pattern with the following stages: replication stage and adaptive immunity stage. After adaptive immunity stage, the clinical symptoms of patient include cough, fever, runny nose, shortness of breath and many more. To cope with this COVID-19, food and nutrition played an important role.

The biological effects of SAEE on PANC-1 and 293/KDR cells were investigated using MTT (3–(4, 5-dimethylthiazole-2-yl)-2,5-diphenyl tetrazolium bromide) assay, DAPI (4',6-diamidino-2-phenylindole) and AnnexinV/propidium iodide (PI) staining.

These results suggest that SAEE could induce apoptosis in cancer cells via a mitochondrial dependent pathway. Furthermore, GC-MS analysis showed that the SAEE is rich in γ-sitosterol and γ-tocopherol.

Statistical analysis was conducted to evaluate differences among groups before and after the intervention.\u0000\u0000\u0000Findings\u0000Treatment with two different doses FFCL (50 and 100 mg/200 g BW/d) and one dose of allopurinol (1.8 mg/200 g BW/d) for 2 weeks significantly reduced UA from 8.04 ± 0.23 to 3.88 ± 0.10; 8.03 ± 0.18 to 2.87 ± 0.10; 8.23 ± 0.21 to 2.53 ± 0.19 (p < 0.05), respectively. The oxidative stress marker malondialdehyde levels were reduced (p = 0.001) from 9.68 ± 0.28 to 4.06 ± 0.58; 10.01 ± 0.23 to 2.12 ± 0.09; 9.88 ± 0.21 to 2.02 ± 0.17 (p = 0.001). The inflammatory marker tumor necrosis factor-α (TNF-α) levels were also reduced from 26.43 ± 0.87 to 12.20 ± 0.32; 27.38 ± 0.53 to 9.60 ± 0.53; 27.55 ± 0.68 to 8.83 ± 0.21 with p = 0.001. The 100 mg/200 g BW/d FFCL decreased UA levels, oxidative stress and inflammatory markers more extensively compared to 50 mg/200 g BW/d FFCL.\u0000\u0000\u0000Research limitations/implications\u0000This study includes some limitations that may affect the generalizability of its findings. First, the flavonoid levels of FFCL were not measured. Second, other oxidative stress biomarkers (e.g. superoxide dismutase) and inflammatory biomarkers (e.g. IL-6) were not investigated. Finally, the experiments were conducted on the model animals over a relatively short period of time. Further research is needed to evaluate the effect in humans at chronic use.\u0000\u0000\u0000Practical implications\u0000Chayote (Sechium edule (Jacq.) Sw) leaves are rich in flavonoids, especially apigenin and luteolin, which can improve oxidative stress and inflammation conditions caused by hyperuricemia.\u0000\u0000\u0000Social implications\u0000Hyperuricemia is a risk factor for non-communicable diseases, mostly caused by oxidative stress and inflammation in the body due to high levels of UA, one of the treatment strategies is through diet modification.\u0000\u0000\u0000Originality/value\u0000The results of this investigation imply that the administration of the flavonoid fraction of chayote leaves has significant effects on UA and oxidative stress and inflammatory markers. Further research is necessary to confirm the results.\u0000","PeriodicalId":19376,"journal":{"name":"Nutrition & Food Science","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2021-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47518057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
