The present study investigated the chemical composition and antioxidant activity of clove essential oil (CEO) and its addition to sesame oil. Methods: composition and antioxidant activity of clove essential oil The CEO was prepared and analyzed by GC-MS. Then, total phenolic content (TPC), antioxidant activity and ferric reducing antioxidant power (FRAP) were determined. The CEO at different concentrations (0.02, 0.04, 0.06, and 0.08%) and TBHQ (0.02%) were added to sesame oil and samples were stored at 60 °C for 5 weeks. Peroxide value (PV), p-Anisidine value (p-AV), total oxidation (TOTOX) value and Thiobarbituric acid reactive substances (TBARs) were determined in sesame oil samples every week for 35 days. A total of 5 components including eugenol (96.25%), eugenol acetate (1.88%), trans-Caryophyllene (1.66%), α-humulene (0.16%), and caryophyllene oxide (0.06%) were determined as the main components of CEO. Results: The TPC of CEO was 345.95±7.85 mg GAE/g. Moreover, the antioxidant activity of CEO for DPPH (IC50) and FRAP methods was estimated 0.83 ± 0.11 mg/ml and 112.37±8.81 mM Fe2SO4. It was shown that peroxide, p-AV, TOTOX, and TBARS values of all sesame oil samples increased during 5 weeks of storage at accelerated conditions. TBHQ showed better function in preventing oil oxidation, but CEO had acceptable function especially in 0.08% concentration. Conclusion: The CEO in vegetable oil due to high phenolic content could retard lipid peroxidation. It could be mentioned that CEO could be considered as an alternative of synthetics ones in vegetable oils.","PeriodicalId":32114,"journal":{"name":"Journal of Nutrition and Food Security","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46542969","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}

The severity and mortality of COVID-19 are affected by several preexisting comorbidities such as type 2 diabetes mellitus (T2DM). A more severe complication of COVID-19 in patients with diabetes could be due to the fact that hyperglycemia and insulin resistance, as important features of diabetes mellitus, are associated with a higher expression rate of angiotensin-converting enzyme-2 (ACE-2). ACE-2 can act as the entry site for SARS-CoV-2 to lung cells. Furthermore, in diabetes mellitus, increased inflammatory responses and impaired immune function are often present. Glycemic index (GI) and glycemic load (GL) are the characteristics of the diet that can affect glycemic control and insulin resistance. These two characteristics could possibly affect infections through their effect on gut microbiota composition, free radical synthesis, and mitochondrial loading. Therefore, it can be proposed that dietary GI and GL might be important factors in the development of COVID-19.","PeriodicalId":32114,"journal":{"name":"Journal of Nutrition and Food Security","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48271792","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}

Aging, smoking and alcohol, stressful life, and family history are directly related to PUD. Oxidative stress and inflammation are the most important mechanisms involved in PUD. The aim of this study is to evaluate the association of dietary inflammatory index (DII) with the risk of PUD. \u0000Methods: In this case-control study, data from 100 newly diagnosed peptic ulcer patients and 150 healthy individuals were analyzed. DII was assessed based on dietary intake data collected through a 174-item validated food frequency questionnaire (FFQ). To calculate DII, 36 nutrients and food components were used after adjusting the energy intake. Adjusted odds ratios (OR) and 95% confidence intervals (CI) regarding the association between DII and PUD risk were estimated by logistic regression. \u0000Results: The mean DII score in patients (0.43±1.88) was significantly higher than the mean DII in healthy individuals (-2.88±2.00) (P=0.005), i.e. patients had received more inflammatory diet. In the crude model of PUD, odds increased significantly in the third and fourth quartiles of DII score compared to the lowest quartile (OR of third quartile vs first quartile: 2.65, 95% CI:1.27-5.52, respectively; and OR of fourth quartile vs first quartile: 2.33, 95% CI:1.12-4.85, respectively; P- trend=0.001). After checking multiple potential confounders, OR in third and fourth quartiles remained high and there was no change in the results. \u0000Conclusions: These findings suggest that more pro-inflammatory diets, indicated by higher DII scores, may increase the risk of PUD. Therefore, anti-inflammatory diet may play a protective role against PUD.","PeriodicalId":32114,"journal":{"name":"Journal of Nutrition and Food Security","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43822771","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}

Leghemoglobin is produced in response to presence of bacteria belonging to Rhizobia family. Structurally, leghemoglobin is similar to hemoglobin and has a kind of heme iron structure. Study of leghemoglobin as a heme iron containing agent can open up a new way for treatment and natural prevention of iron deficiency anemia and substitution with mineral iron salts. \u0000Methods: Five different cultivars of alfalfa plants including Esfahani, Bammi, Yazdy, Nik shahri, and Hamedani were cultivated in gardening farm of the faculty of agriculture in Shahid Chamran University in a linear form. Cultivation was done with biological fertilizer containing Sinorhizobium meliloti for test groups and without fertilizer for sham groups. After 60 days, the samples were harvested, and the amount of leghemoglobin produced in nodules was quantified using LaRue and Child fluorometric method. \u0000Results: The results from five cultivars of alfalfa planted with biological fertilizer showed a significant increase in viscosity of leghemoglobin in nodules of the test group in comparison with sham group (P<0.0001). Moreover, the high viscosity of leghemoglobin in nodules of Bammi cultivar indicated the capacity of this plant to produce leghemoglobin in Ahvaz. \u0000Conclusion: According to the findings of this study, Bammi cultivar of alfalfa is a good option for future studies and even production of high amounts of leghemoglobin in Khuzestan Province.
