Background: Recently due to adverse effects of synthetic antioxidants, there has been a growing interest in the application of natural essential oil in vegetable oils. 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.
背景：近年来，由于合成抗氧化剂的不良影响，人们对天然精油在植物油中的应用越来越感兴趣。本研究考察了丁香精油及其在芝麻油中的化学成分和抗氧化活性。方法：采用气相色谱-质谱联用技术，制备丁香精油CEO的成分及抗氧化活性。然后测定了总酚含量（TPC）、抗氧化活性和铁还原抗氧化能力（FRAP）。将不同浓度（0.02、0.04、0.06和0.08%）的CEO和TBHQ（0.02%）加入芝麻油中，并将样品在60°C下储存5周。每周测定芝麻油样品中过氧化值（PV）、对苯胺值（p-AV）、总氧化值（TOTOX）和硫代巴比妥酸反应物质（TBARs），连续35天。丁香酚（96.25%）、丁香酚醋酸酯（1.88%）、反式石竹烯（1.66%）、α-胡烯（0.16%）和石竹烯氧化物（0.06%）共5种成分被确定为CEO的主要成分。结果：CEO的TPC为345.95±7.85mgGAE/g。此外，CEO对DPPH（IC50）和FRAP方法的抗氧化活性估计为0.83±0.11 mg/ml和112.37±8.81 mM Fe2SO4。结果表明，在加速条件下储存5周期间，所有芝麻油样品的过氧化物、p-AV、TOTOX和TBARS值均增加。TBHQ具有较好的防油氧化作用，但CEO在0.08%浓度时具有较好的抗氧化作用。结论：植物油中的CEO由于酚类物质含量高，可延缓脂质过氧化。可以提到的是，CEO可以被认为是植物油中合成物的替代品。

In 2019, a new coronavirus causing a flu-like syndrome was discovered in Chinese province of Hubei and there was a subsequent outbreak in Wuhan in December 2019. 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.

Background: Nowadays, increasing the use of pesticides to manage the agriculture production resulted in increased pesticide residues in final products and concerns about environmental pollution and prevalence of emerging diseases. This study aims to investigate the residual amount of Phosalone toxin in the early and late varieties of peach orchards in Saman city located in Chaharmahal and Bakhtiari province. Methods: In this study, 60 samples of early and late peach varieties of peach orchards were selected randomly. Phosalone residues in early and late peach varieties before and after washing, and after peeling were extracted by QUECHERS method and the amount of extracted toxin were measured by high-performance liquid chromatography (HPLC). The data were analyzed using SPSS v.24 software. Results: Phosalone residues in early peach varieties before and after washing were 3.55 ± 0.94 and 0.31 ± 0.29 mg/kg, respectively. The concentration of Phosalone residues in unwashed early and late peach varieties before washing was 3.17 ± 0.97 mg/kg but decreased to 0.64 ±0.74 mg /kg after washing. Peeling reduced 97.79% of the Phosalone residues in late peach. Early and late peaches covered by the plant pathology clinic and unwashed late peaches not covered by plant pathology clinic were significantly (P < 0.05) higher than the Iranian national standard (2 mg/kg). Conclusion: Washing and peeling the peach significantly decreased the toxin residues. In order to minimize the risk of exposure to Phosalone residues, integrated pest control management programs are essential.

Background: Peptic ulcer disease (PUD) is a gastrointestinal ulcer caused by gastric acid. 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. Methods: 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. Results: 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. Conclusions: 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.

Background: Childhood obesity and overweight have become major public health problems worldwide. To combat this problem, effective, sustainable, and consistent strategies are needed. In this study, the long-term effect of a school-based intervention for weight reduction was evaluated in primary school students in Tehran, Iran. Methods: This was a cluster randomized controlled trial (RCT) conducted in 12 primary schools in a low- to middle-class district in Tehran, Iran. The participants were 334 overweight or obese primary school students (girls =164) based on World Health Organization standards, equally distributed in the intervention (n=167) and comparison (n=167) groups. It was a multi-component intervention and included nutrition education and increased physical activity (PA), a lifestyle modification program for parents, and changing the food items sold in canteens of the schools. Body mass index Z-score [BMI-Z] was determined as the primary outcome and measured at baseline, three months after baseline, at post-test (after 18 weeks), and follow-up (13-month). In total, 205 students (59.5%) completed the follow-up. Analyses were carried out based on the intention-to-treat principle using linear mixed models. Results: After 13 months, the BMI Z-score decreased in both intervention and comparison groups. However, the change was more significantly observed in the intervention group (adjusted change: 0.098, 95% CI: (0.03-0.16) compared with comparison group (P=0.003(. The intervention had a more significant effect on BMI Z-score among girls (adjusted change: 0.36, 95% CI: (0.27-0.45) compared with the comparison group (P<0.001)( than among boys (adjusted change: -0.14, 95% CI: (-0.23- -0.05) compared with the comparison group (P=0.002). Conclusion: The intervention was an effective way to reduce BMI in the girls and the effect lasted for a relatively long time.

Background: Water quality is the most important factor for consumers. Therefore, monitoring and controlling water quality is of particular significance in different human communities such as universities. The aim of this study was to investigate the quality of drinking water in some universities in Iran. Methods: In this study, the physicochemical parameters and heavy metals including lead, cadmium, nickel, arsenic, and chromium in drinking water were determined in nine Iranian universities. Then, the efficacy of several treatment methods was evaluated in the removal of heavy metals, including boiling process in two stages, 5 min boiling, 5 h boiling, and filtration process. Results: Physicochemical properties of drinking water in all samples were appropriate. Hardness levels were higher than the World Health Organization standards. However, this parameter was lower than the national standard of Iran (500 mg/l caco3). Nevertheless, cadmium content was not detected in any samples, and nickel and chromium content was below the permissible limit. Lead content was equal to the limit in three samples, and arsenic content was equal to the limit in four samples. Water purification methods including boiling and water purifier were satisfactory and significantly reduced pollutants. Conclusion: It is suggested to check drinking water quality in universities randomly.

Background: Leghemoglobin is an oxygen transporter and a hemoprotein found in nodule roots of nitrogen fixator plants from Leguminosae family. 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. Methods: 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. Results: 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. Conclusion: 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.

Background: Food insecurity is recognized as a serious public health problem worldwide. Since pregnant women are among the most vulnerable groups and their food insecurity may cause complications during pregnancy and on their newborns, the aim of this study is to investigate the relationship between food security and body mass index (BMI) of pregnant women in eastern Iran. Methods: This cross-sectional study was conducted on 335 pregnant women in 10 health centers in the east of Iran. Participants were selected by random cluster sampling. Data were collected using standard questionnaires including 18-item household food security survey module (HFSSM) designed by the U.S. Department of Agriculture (USDA) and nutritional evaluation forms. Results: The mean scores of the HFSSM of all pregnant women were 7.2±4.3. The household food security of pregnant women was significantly related to the occupation of spouses, mother's education, monthly salary, private home, and mother's age (P<0.05). There was no significant relationship between food security and BMI (P=0.98). Conclusions: Based on the results, few people have food security. Pregnancy in older age, lower-income, and education affected the household food security. Appropriate strategies and policies are necessary to combat this problem.

Background: Autochthonous fruits such as Guavijú have beneficial health properties through their bioactive compounds and antioxidant capacity. This study aims to evaluate nutritional composition, phytochemical performance, total content of polyphenols, antioxidant capacity, and bioactive compounds of Guavijú (Eugenia pungens) fruits. Methods: Macronutrients were analyzed using Anthrona method for carbohydrates, Kjeldahl method for proteins, and Soxhlet method for total fat. Phytochemical screening was performed to detect phenols, flavonoids, saponins, alkaloids, steroids and triterpenoids, as well as leukoanthocyanidins and quinones. The total content of polyphenols was obtained using Folin-Ciocalteu method. Antioxidant capacity was determined by ORAC method, and the identification of bioactive compounds was carried out through LC-QqQ MS/MS. Results: Macronutrients were found in proportions of 33.4%, 5.5%, and 4.5% for carbohydrates, proteins, and fats, respectively. Phytochemical screening revealed the presence of phenols and triperthenoids. The total polyphenol content was 46.6 mg/g. Antioxidant capacity was 11394±705 μmol/100 g. Conclusions: The identified bioactive compounds were cyanidin, delphinidin, enotein B, quercetin, and myricitrin. The results revealed that beneficial health properties due to the content of bioactive compounds and antioxidant capacity, which constitutes a food, can prevent diseases.
