Honey and Apoptosis in Human Gastric Mucosa

Background: Gastric cancer is the fourth most common malignancy in the world. Honey is acomplex mixture of special biological active constituents. Honey possesses antioxidant and antitumorproperties. Nutritional studies have indicated that consumption of honey modulates therisk of developing gastric cancer. On the other hand, apoptosis has been reported to play a decisiverole in precancerous changes. Our chief study was conducted to assess the relationship betweenconsumption of honey and apoptosis in human gastric mucosa.Method: This cross-sectional study was conducted on 98 subjects over 18 years old, referred totwo hospitals in Tabriz, Iran. Subjects were undergone an upper gastrointestinal endoscopy, 62subjects were finally enrolled. Honey consumption was assessed by a Food Frequency Questionnaire(FFQ) and apoptosis was detected by TUNEL technique. We tested polynomial curve tofind the best fit between honey consumption and apoptosis.Results: A positive relation between honey consumption and apoptosis was found (P=0.024).Our results indicated that the final and the best fit curve was: apoptosis = 1.714+1.648(honeyamount) - 0.533(honey amount)2 +1.833×10-5(honey amount)7.Conclusion: Honey consumption had positive effects on gastric cancer by inducing apoptosis ingastric mucosa

The impact of Supplementation With Fish Oil on Lipid Profile of Pregnant Mothers: A Randomized Controlled Trial

Objective: The impact of supplementation with omega-3 fatty acid during gestational period on lipid profile levels remains unknown. The objective of this trial was to investigate the impact of supplementation with fish oil on maternal lipid profile. Materials and Methods: This research was a randomized triple blinded controlled trial. The study population was comprised healthy pregnant subjects who had family records at health care centers in Tabriz, Iran. A total of 150 women who were eligible for study were randomized into two groups, one group took fish oil supplement capsules (1000 mg/day), and another group took placebo. A total of 92 women fulfilled the study which 45 participants were in the supplemented group and 47 participants were in the placebo group. Consumption of fish oil capsules and placebo was daily one capsule from the beginning of the 21th week of gestation until delivery which was about 20 weeks. At the start of trial (16th-20th weeks) and in the fifth care of gestation (during 35th-37th weeks) 3 cc blood samples collected and sent to the laboratory for evaluation of lipid profile levels. Results: Despite substantial increases in total cholesterol, triglycerides and Low-density lipoprotein (LDL) levels with advancing pregnancy, there was no statistically significant discrepancy between the intervention and placebo groups. (P = 0.345, 0.299, 0.109, respectively). Despite a significant decrease in the levels of high-density lipoprotein (HDL) cholesterol with advancing pregnancy, there was no statistically meaningful difference between two groups (P = 0.786) Conclusion: We found no effect of supplementation with fish oil during gestation on plasma lipid profile of pregnant mothers

Oleoylethanolamide Supplementation Reduces Inflammation and Oxidative Stress in Obese People: A Clinical Trial

Purpose: Obesity as a serious public health problem worldwide, results in the incidence of many chronic diseases. Obesity has been recognized as a chronic low-grade inflammation disorder. Altered endocannabinoid system tone is also involved in the pathogenesis of obesity. The present study aimed to investigate the effects of oleoylethanolamide supplementation on inflammatory biomarkers and oxidative stress in obese people. Methods: This randomized, double-blind, placebo-controlled clinical trial was carried out on 60 healthy obese people in 2016 in Tabriz, Iran. Eligible subjects were randomly divided into intervention (received daily, two 125 mg OEA capsules) and control groups (the same amounts of starch) and treated for 8 weeks. Blood samples (5 ml) were taken in fasting state at the baseline and at the end of the study. The concentrations of MDA and TAS were measured using a spectrophotometer. A high sensitive-C reactive protein level was measured by Immunoturbidimetry assay using the commercial kit. IL-6 and TNF-α levels were assayed by the ELISA method. The differences between groups were assessed by ANCOVA and statistical significance was determined at p0.05). Conclusion: The use of OEA as a complementary pharmacotherapy agent could be effective in improving inflammation and oxidative stress in obese people. Future studies are needed to confirm the obtained results

Effects of Zinc Supplementation on the Anthropometric Measurements, Lipid Profiles and Fasting Blood Glucose in the Healthy Obese Adults

Purpose: The aim of this study was to assess the effects of zinc supplementation on anthropometric measures, improving lipid profile biomarkers, and fasting blood glucose level in obese people. Methods: This randomized, double- blind clinical trial was carried out on 60 obese participants in the 18-45 age range for one month. The participants were randomly divided into the intervention group, who received 30 mg/d zinc gluconate, and the placebo group who received 30mg/d starch. Anthropometric measurements (body mass index (BMI), weight and waist circumference) were recorded before and at the end of study. Lipid profile biomarkers and fasting blood glucose were determined using enzymatic procedure. Analysis of Covariance (ANCOVA) test was run to compare the post-treatment values of the two groups, and t-test was conducted to compare within group changes. Results: Serum zinc concentration was increased significantly in intervention group (p=0.024). BMI and body weight was significantly decreased (p=0.030 and p=0.020, respectively). Lipid profile biomarkers and fating blood glucose did not change significantly but triglyceride level was significantly decreased (p=0.006) in the intervention group. Conclusion: The obtained results indicate that zinc supplementation improves BMI, body weight, and triglyceride concentration without considerable effects on lipid profile and glucose level. Zinc can be suggested as a suitable supplementation therapy for obese people, but more studies are needed to verify the results

The Efficacy of Nigella sativa L. and Curcumin Nanomicelle Alone or Together on Lipid Profile, Glycemic Control Indices, and Serum 17-Β Estradiol in Postmenopausal Women

Introduction: Menopause is a condition for metabolic disorders. This study aimed to evaluate the effect of Nigella sativa (NS), curcumin nanomicelle (CN), lipid profile, glycemic status and 17-β estradiol (ES) levels in postmenopausal women. Methods: Triple-blind randomized clinical trial was conducted on 120 postmenopausal women. Participants were randomly assigned to four groups: 1) NS capsule 1000 mg and CN placebo, 2) 80 mg CN capsule and NS placebo, 3) both NS and CN capsules and 4) NS and CN placebo. Participants received a single dose daily for 6 months. The serum lipid profile, glycemic control biomarkers, and ES were measured pre-and post-intervention using biochemical methods. Results: Total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL) and low-density lipoprotein (LDL) cholesterol, fasting blood sugar (FBS), fasting insulin (FI), insulin resistance (IR), and ES showed significant improvement in NS group. CN significantly reduced TC, FI, and IR, and significantly increased ES. The combination of NS-CN significantly decreased TC, LDL, FI, and IR, and increased HDL and ES. The comparison of the studied with the placebo groups showed that these changes were significant in glycemic indices and NS significantly increased estrogen. Conclusion: NS, CN and NS-CN improved lipid profiles, blood sugar, and hormone levels. However, this improvement was significant in glycemic indices and estrogen levels compared to the placebo group. No superiority of combined NS-CN over NS or CN was found in this trial

In this paper, we seek to use the Fuzzy analytical network process (FANP) for analysis of food insecurity surveillance and selecting the best strategies for improving it. This cross-sectional study was conductedon 300 subjects (132 male and 168 female) selected randomly in the Asadabadi area of the northwest of Iran.The method is validated using the structural validation approach

Does long sleep duration increase risk of metabolic syndrome in Azar cohort study population?

Background: We decided to assess the correlation between metabolic syndrome (MetS) risks,sleep and napping duration in Azar cohort population according to the increasing incidence of MetS in the world and inconsistence results about sleep duration and MetS. Methods: In this cross-sectional study, MetS and sleep habits of 14916 subjects (35-70 years old) who inhabited in Shabestar city were determined by ATPIII and Pittsburg questionnaire respectively. Inclusion criteria were subjects with 35-70 years old and living in Shabestar for at least 9 months of the year.Results: According to the results, age, living place, body mass index, hypnotic drug use, sleep and napping duration and TV time were the risk factors of MetS. In this regard, long sleep duration (>9 h/24 h), napping (0.25-2 h/day), hypnotic drug use and watching TV (2 h/day)increased the risk of MetS by 1.18 (1.05-1.33), 1.16(1.07-1.26), 1.35(1.13-1.60), and 1.13(1.04-1.23) respectively.Conclusion: According to these results, it appears that proper education for improvement of sleep habit is necessary to reduce incidence of MetS and its consequences. However, there is need for more longitudinal researches and using objective method of sleep habits evaluation for more precise results

The Influence of β-Alanine Supplementation on Recovery Biomarkers in Adults: A Systematic Review and Meta-Analysis

Background: Clinical studies, investigating the effect of β-Alanine (BA) supplementation on recovery biomarkers in physically active individuals, have generated inconsistent results. This systematic review and meta-analysis study aimed to clarify the clinically relevant dietary effects of BA supplementation. Methods: A comprehensive search was done in the electronic databases of Scopus, PubMed, ISI Web of Science and Embase from inception to 2022. Meta-analysis was done using the random-effects model. Pooled effect size was evaluated using standard mean difference (SMD) and 95% confidence intervals (CI). Heterogeneity of between-study was evaluated according to Cochran’s Q test and I2 . Subgroup analysis was conducted to identify the potential sources of heterogeneity. Results: Overall, 32 studies were included in the current study. The results suggested that BA supplementation increases carnosine level significantly (SMD: 0.22mmol/L, 95%CI: -0.17, 0.61, P=0.27) but no effect was shown about lactate, fatigue, VO2 , pH and bicarbonate (HCO3 - ) (P>0.05). Subgroup analysis revealed a significant association of VO2, carnosine and fatigue with supplementation dosage, gender and duration of administration respectively. Conclusion: BA supplementation emerged its beneficial effects on enhancing carnosine level which highlights its ergogenic effects. In contrast, no significant effects had been shown in term of fatigue delay and blood levels of lactate, HCO3 - , pH, and VO2 value. These results warrant more investigation in a prospective design to clarify the exact mechanism in this way

Prealbumin/CRP Based Prognostic Score, a New Tool for Predicting Metastasis in Patients with Inoperable Gastric Cancer

Background. There is a considerable dissimilarity in the survival duration of the patients with gastric cancer. We aimed to assess the systemic inflammatory response (SIR) and nutritional status of these patients before the commencement of chemotherapy to find the appropriate prognostic factors and define a new score for predicting metastasis. Methods. SIR was assessed using Glasgow Prognostic Score (GPS). Then a score was defined as prealbumin/CRP based prognostic score (PCPS) to be compared with GPS for predicting metastasis and nutritional status. Results. 71 patients with gastric cancer were recruited in the study. 87% of patients had malnutrition. There was a statistical difference between those with metastatic (n=43) and those with nonmetastatic (n=28) gastric cancer according to levels of prealbumin and CRP; however they were not different regarding patient generated subjective global assessment (PG-SGA) and GPS. The best cut-off value for prealbumin was determined at 0.20 mg/dL and PCPS could predict metastasis with 76.5% sensitivity, 63.6% specificity, and 71.4% accuracy. Metastatic and nonmetastatic gastric cancer patients were different in terms of PCPS (P=0.005). Conclusion. PCPS has been suggested for predicting metastasis in patients with gastric cancer. Future studies with larger sample size have been warranted
