Dietary modification can affect sleep quality. Thus, the aim of this present study was to investigate the correlation between adherence to the DASH diet and daytime sleepiness score in adolescent girls.Methods: A total of 535 adolescent girls aged between 12 and 18 years old were recruited from different regions of Khorasan Razavi in northeastern of Iran, using a random cluster sampling method. DASH scores were determined according to the method of Fung et al. A Persian translation of the Epworth Sleepiness Scale (ESS-IR) was used to assess of daytime sleepiness. To investigate the correlation between DASH-style diet and daytime sleepiness score, we applied logistic regression analysis in crude and adjusted models.Results: As may be expected, participants with the greatest adherence to the DASH diet had significantly higher intakes of fruits, vegetables, low-fat dairy products, fish and nuts, and lower consumption of refined grains, red and processed meat, sugar-sweetened beverages and sweets. There was an inverse correlation between adherence to the DASH-style diet and scores for daytime sleepiness in crude model (β= − 0.12; P=0.005). These findings were remained significant after adjustment for confounding variables (β= − 0.08 P=0.04).Conclusion: There is an inverse correlation between adherence to DASH diet and daytime sleepiness score. Further studies, particularly longitudinal studies, are required to determine whether dietary intervention may improve daytime sleepiness.Keywords: DASH diet, sleep, adolescents, daytime functioning

Patients and methods: Thirty male Wistar rats randomly were divided into five experimental groups of six animals each. The animals were received 50, 100, 200, and 400 mg/kg CNPs for 14 consecutive days. At the end of the experiment, the rats were euthanized and histopathological evaluation of the liver and renal tissues, as well ass, the markers of serum oxidative stress including thiobarbituric acid reactive substances, total sulfhydryl content, and antioxidant capacity (using ferric reducing/antioxidant power assay) were assessed. Hematological parameters and the activity of liver function enzymes were also measured. Results: The results of this study showed that CNPs caused no significant changes in the activity of liver enzymes, hepatic and renal histopathology and hematological parameters, while significantly improved serum redox status. Conclusion: Acute administration of pullulan-mediated CNPs is safe and possess antioxidant activity. Keywords: green synthesis, metal oxide, sol-gel, toxicology, radical scavenger

Zinc deficiency and excess copper have been reported to be associated with inflammation. The human T-lymphotropic virus type 1 (HTLV-1) is a retrovirus, which is believed to cause systemic inflammation. The aim of this study is to measure levels of Zn, Cu, SOD, and prooxidant–antioxidant balance (PAB) in HTLV-1-positive patients and investigate the association between serum Zn and Cu concentrations and levels of oxidative stress in them.Methods: The serum samples of 1,116 subjects who had participated in the “Mashhad Stroke and Heart Atherosclerotic Disorder” study, including 279 HTLV-1-positive and 837 HTLV-1-negative patients, were used. Levels of Zn, Cu, SOD, and PAB were measured.Results: Zinc and SOD levels were lower in the HTLV-1-positive group; however, the difference was statistically significant only for the level of SOD (P=0.003). On the other hand, levels of copper and PAB were significantly higher in HTLV-1 positive subjects; P=0.004 and P=0.002, respectively.Conclusion: In HTLV-infected patients, serum Zn concentration is lower and Cu concentration is higher than healthy controls. This altered situation might be either primary or secondary to HTLV-1 infection, which should be investigated in larger studies. We showed that SOD is significantly lower in HTLV-1-infected subjects. As in some other viruses that evolve different mechanisms to potentiate virus replication by changing the physiologic condition of host cells, HTLV-1 too probably decreases the activity of copper–zinc SOD1 by suppressing its gene.Keywords: HTLV-1, trace elements, superoxide dismutase, prooxidant-oxidant balance

It affects people of both genders and all age groups, ethnicity and socioeconomic groups, and in developed and developing countries. Obesity is often accompanied by the metabolic syndrome (MetS). MetS is characterized by a clustering of cardiovascular risk factors, including high blood pressure, adiposity, dyslipidemia and glucose intolerance, which together increase the risk of atherosclerotic cardiovascular disease, type 2 diabetes mellitus and other causes of mortality. Nowadays, there is a growing interest in the use of plant-based agents instead of synthetic drugs to manage chronic diseases such as MetS; one such example is Berberis vulgaris. B. vulgaris contains isoquinonline alkaloids such as berberine, berberrubine and berbamine. Recent studies have proved that berberine exhibits pharmacological activities and positive effects on the risk factors of obesity and MetS. We have reviewed original articles related to the possible molecular mechanisms of action of berberine on obesity and MetS. Berberine suppresses adipocyte differentiation and decreases obesity. It also regulates glucose metabolism via decreasing insulin resistance and increasing insulin secretion. Other effects of berberine include antihyperlipidemic and antihypertensive activities and endothelial protection. Keywords: berberine, syndrome metabolic, obesity

BACKGROUND/OBJECTIVES: Obese infants are more susceptible to develop adulthood obesity and its related comorbidities. Previous studies have shown the presence of hormones and growth factors in maternal breast milk that may influence infant adiposity. The aim of this study was to investigate differences in concentrations of three hormones and two growth factors in the breast milk of mothers with obese and non-obese infants. SUBJECTS/METHODS: In this cross-sectional study, 40 mothers with overweight or obese infants (weight for length percentile >97) and 40 age-matched mothers with normal-weight infant (-10 < weight for length percentile < 85) who were between 2 and 5 months of age were enrolled. Anthropometric indices of infants and mothers were measured by routine methods. Breast milk concentrations of ghrelin and adiponectin, leptin, epithelial growth factor (EGF) and insulin-like growth factor-1 (IGF-1) were measured using enzyme-linked immunosorbent assay methods. RESULTS: The mean breast milk concentration of ghrelin was higher in mothers with normal-weight infants, 137.50 pg/ml, than in mothers with obese infants, 132.00 pg/ml (P =0.001). This was also true regarding the concentration of EGF in mothers with (0/04 ng/ml) and without (0/038 ng/ml) normal-weight infants (P = 0.01). No significant differences were observed in concentrations of leptin, adiponectin and IGF-1 between two groups (P>0.05). There was also a significant positive correlation between EGF and ghrelin in both groups. CONCLUSIONS: This study revealed that there was a correlation between ghrelin and EGF level in breast milk of mothers with obese and non-obese infants, suggesting a possible regulatory effect of these two hormones on weight in infants.

OBJECTIVE: The aim of this study was to investigate the relationship between dietary intake and biomarkers of cardiovascular risk in individuals with and without angiographically defined coronary artery disease. SUBJECTS/METHODS: Coronary angiography was undertaken in 445 individuals who were divided into those with significant disease (>50% occlusion) (Angio+ (n = 273)) and those with RESULTS: Concentrations of starch, saturated fatty acids, polyunsaturated fatty acids, magnesium, iron and copper in the control group were less than those in the other groups (P CONCLUSIONS: These results indicate that the amount of intake of various nutrients can be considered as an independent risk factor for CAD. Further research on the relationship between CAD and nutrient intake, especially intake of essential micronutrients, is needed.

Objective To undertake a randomized controlled trial in 196 obese subjects to examine the effect of electro-acupuncture on serum pro-oxidant antioxidant balance (PAB) values. Methods Subjects received authentic acupuncture (cases) or sham acupuncture (controls) for 6 weeks in combination with a low-calorie diet. In the following 6 weeks, they received the low-calorie diet alone. Serum PAB was measured at baseline, and 6 and 12 weeks later. Results We found that serum PAB values decreased significantly in the group receiving the authentic acupuncture compared to the sham treatment (p<0.001) at week 6, and whilst serum PAB increased significantly (p<0.05) in the second phase of the study, a significant difference between two groups remained at 12 weeks (p<0.05). Conclusions Electro-acupuncture in combination with a low-calorie diet was more effective at reducing serum PAB values in obese subjects compared to diet alone. Further work is required to determine the mechanism by which electro-acupuncture has this effect. [ABSTRACT FROM AUTHOR]

BACKGROUND AND AIM: Obesity is a major risk factor for type 2 diabetes mellitus and cardiovascular disease (CVD). Little is known about the metabolic profile across categories of body mass index (BMI), particularly within Asian populations. We assessed the prevalence and distribution of body size phenotypes among Iranian adults from a representative sample from Mashhad. METHOD: The Mashhad Stroke Heart Atherosclerosis Disorder (MASHAD) study cohort of 9761 adults (3903 men) aged 35-65 years were cross-categorized by BMI and metabolic status into: normal-weight metabolically healthy (NWMH), normal-weight metabolically abnormal (NWMA), overweight metabolically healthy (OvMH), overweight metabolically abnormal (OvMA), obese metabolically healthy (OMH) and obese metabolically abnormal (OMA). Metabolic normality/ abnormality was defined by the presence of any two of the following: 1) elevated blood pressure or known hypertension on treatment, 2) high serum fasted triglycerides; 3) low serum HDL-cholesterol, 4) high blood glucose or the presence of diabetes mellitus, 5) serum CRP > 90th percentile. RESULTS: The distribution of obesity phenotypeswas 11.6% (NWMH), 15.6% (NWMA), 10.6% (OvMH), 31.3% (OvMA), 4.9% (OMH), and 25.5% (OMA) overall. Equivalent figures were 13.1%, 24.0%, 7.7% 37.3%, 1.5% and 16.2% in men; 10.7%, 10.2%, 12.5%, 27.4%, 7.2% and 31.8% inwomen, p < 0.001 for gender differences. Multi variables logistic regression models comprising age gender and each of the metabolic factors was associated with 3.2% to 5.3% variations in BMI categories. CONCLUSION: The present study showed that a considerable proportion normal-weight Iranians display cardiometabolic abnormalities especially men, while a significant percentage of obese individuals, particularly women are metabolically healthy.

Background: Heat shock protein 27 (HSP27) is an intracellular chaperone constitutively expressed in many cell types including cardio myocytes and endothelial cells. Circulating levels of HSP27 and anti-HSP27 antibody are higher in patients with CVD. Anti-HSP27 antibody concentrations were also reported to be increased in atherogenesis. We aimed to evaluate serum anti-HSP27 antibody titers in individuals with, or without, MetS in the MASHAD study cohort with large sample size in 6,568 subjects.
