The purpose of this investigation was to determine and compare the effects of leucine (Leu), valine (Val), isoleucine (Ilue), and combined branched chain amino acids (BCAA) supplementation, on markers of muscle damage following resistance exercise. It was hypothesized that supplementation would attenuate the levels of indirect muscle damage markers and muscle soreness following exercise-induced muscle damage, and facilitate the restoration of muscle function. A total of 50 untrained males were randomly divided into five groups; Leu (n = 10), Ilue (n = 10), Val (n = 10), BCAA (n = 10), and placebo (n = 10). The muscle damage protocol specific to non-athletes is used in the current study. A 500 ml of group-specific solution was given to each group in two time points, 30 minutes before and immediately after performing the exercise. Multivariate analysis showed significant time differences for LDH in all groups (p<0.05); there were significant multivariate time differences in all groups regarding creatine kinase (CK) (p=0.000 for all groups). A significant time differences observed in all groups regarding repetition maximum [RM] (p<0.01) and pain (p=0.000 for all groups). The results of this investigation show that compared to combined BCAA, Ilue or Val; Leu provides more protective effect on attenuating the immediate increase in biochemical markers of muscle damage following eccentric-based resistance exercise, while combined BCAA may aid to maintain the range of motion. Additionally the results showed that perceived pain by individuals in the placebo group was significantly higher compared to all other groups. Hence, BCAA intake, especially Leu, in the dosage used in this investigation is ergogenic for untrained males.

Patients with Chronic Obstructive Pulmonary Disease (COPD) usually have a decreased muscle function capacity and pulmonary functions. The purpose of this study was to determine the effect of enteral nutrition support given in addition to diet on muscle function capacity, forced expiratory volume in second (FEV1) and tiffeneau index (FEV1/FVC) in malnourished patient with COPD. Forty patients with body mass indexes (BMI) below 18.5 kg/m2 were included in the study. Nutrition education was given to all patients then the patients were divided into two groups as treatment and control. Treatment group consumed two bottles of enteral nutrition product in addition to oral nutrition for three months. The muscle powers of the patients were measured with handgrip dynamometer and their FEV1 and FVC values were determined with pulmonary function tests, and tiffeneau indexes were calculated in the beginning and at the end of the study. In conclusion, enteral nutrition support increased hand grip strength and FEV1 without any significant effect on FEV1/FVC values in malnourished patients with COPD.

Background. High-protein diets are often used as a quick and easy way to achieve weight loss in those who are overweight or obese. People using for a long time this type of diet are not aware that it can cause serious health problems, therefore it is very important to monitor the effects of long-term use of high-protein diets. Aim. The aim of this study was to evaluate the high–protein diet (Dukan Diet) and after its completion, as well as to assess the nutritional status of women on the basis of biochemical parameters of blood: morphology, blood sugar, lipid profile and hepatic profile, in order to determine the health consequences of the high-protein diet. Material and Methods. The study included 32 women aged 19 to 56, who had followed the Dukan Diet in the past (2 year ago). A 7-day nutrition diary was used to assess nutrition after the Dukan Diet, where 5 days were working days and 2 days were non-working days. Nutritional status was assessed on the basis of anthropometric measurements and the morphological and biochemical parameters of blood: blood count, fasting blood glucose levels, lipid profile, the profile of the hepatic were analyzed in an accredited analytical laboratory, and these values were determined using haematological and biochemical indicators measured on an Analyzer at Sysmex K-1000 and Vitalab Flexor, respectively. Results. The resulting analysis shows that women did not receive adequate amounts of energy from the diets. Diets were deficient in terms of most nutrients, while in other cases the values exceeded the recommended standards. Analysis has shown that the Dukan Diet is deficient in many vitamins, including vitamins C and B, nor does this diet provide a sufficient amount of dietary fiber. It has been observed of minerals deficiency (iron, magnesium, copper) both during and after the protein diet. Moreover, subjects revealed an increased concentration of eosinophils, basophils, monocytes, triglycerides, LDL cholesterol, glucose in the blood. Conclusions. The diet of women after the end of high-protein diet is still abnormal as evidenced by improper blood chemistry markers. Women should be under the control of a dietitian.

New functional foods are increasingly sought to improve the treatment of diseases related to glucose and lipid metabolism. The present study was designed to investigate the possible antidiabetic and antioxidant effects of goldenberry and lupin on brain and muscle tissues of streptozotocin-induced type II diabetic rats. Type II diabetes was produced in albino rats by the streptozotocin injection. Wistar albino rats were divided into four groups, each one containing 10 rats: non-diabetic control group, STZ- type II Diabetes group, STZ- type II Diabetes+goldenberry group, and STZ- type II Diabetes+lupin group. After one week from the injection, goldenberry and lupin were injected to rats for 2 months. Malondialdehyde, glutathione, cholesterol, and fatty acid levels, which are signs of lipid peroxidation, were measured in brain and muscle tissues. In type II diabetes, malondialdehyde increased compared to the control group. Glutathione decreased in the both tissues and all of the streptozotocin-induced diabetic groups. In type II diabetes, brain cholesterol levels decreased. Treatment with similar doses of goldenberry and lupin significantly reduced oxidative stress, augments antioxidant system and altered fatty acid metabolism in these tissues, thereby maintaining favourable fatty acid distribution affected by diabetic complications. These results validate the use of goldenberry and lupin fruits as a treatment against diabetes mellitus and its complications and suggest it is suitable to continue studies for its safe therapeutic use.

Background/aims: This research aimed to investigate the relationship between eating attitudes and body satisfaction among adolescents attending high school in Ankara, the capital city of Turkey. Methods: The participants were 718 males and 761 females, in total 1479 adolescents aged between 13 and 18 years. The Eating Attitude Test-26 (EAT-26) and Body Cathexis Scale (BCS) were used to assess eating attitudes and body satisfaction respectively. Data from the study were evaluated statistically by chi-square test. Results: Our results showed that 2.93 % of males and 40.07 of females faced a high risk of having an eating disorder. Our findings confirm that females are more at risk of eating disorders. The BCS of males (90.8 ± 20.8) was found significantly higher than females (81.3 ± 16.8) ( p<0.001), which indicates that females are less content than about their appearance. We also found that 6.3 % of males and 18.2 % of females thought that they were overweight, and 22.9% of females and 4.3 % of males perceived themselves as obese. While 58.6 % of males perceived their body image as correct, 65.8 % of females did not (p<0.05). Conclusion: Together these results confirm that female adolescents tend to be less satisfied with their weight and more likely to display disordered eating attitudes.

The aim of this study to investigate the effect of an immunonutritional (IN) oral formula enriched with arginine, omega-3 fatty acids and nucleotides in methotrexate (MTX)-induced experimental intestinal mucositis model. In the study, 32 rats were divided into four groups consisting eight animals in each. Control group fed for 5 days with only saline with gavage, IN group fed for 5 days with an oral IN formula three times a day, MTX group with an intraperitoneal single dose MTX (20 mg/kg), followed by saline with gavage, MTX-IN group with a single dose of MTX, followed by an oral IN formula three times a day. The blood and jejunal tissue sample were collected and then the rats were sacrificed on the sixth day of the study. The level of TNF-α, IL-1β in serum, luminol, lusigenin, glutathione, myeloperoxidase, malondialdehyde and Na-K+ATPase in the jejunal tissue samples were analyzed. Histopathological examination was performed in the jejunal tissue samples. In the MTX group, TNF-α, IL-1β levels in serum, and luminol, lusigenin, malondialdehyde levels, and myeloperoxidase activity in tissue samples were found significantly higher than the control group. Glutathione and Na-K+ATPase levels were lower in the jejunal tissue of the MTX group compared to control group. However, the supplementation of IN with the MTX resulted in a significant increase in glutathione and Na-K+ATPase levels. Severe epithelium loss and inflammatory cell increase were observed in the MTX group on histological examination, whereas these parameters were regressed in the MTX-IN group. Increasing in the mitosis rate of enterocytes and inflammatory cell density decreased with the IN. In conclusion, this study shows that chemotherapy has adverse effects on intestinal mucosa and the IN formula has a protective effect of on MTX-associated intestinal damage.

In the present research, efforts were made to enhance protein content of muffins using non-conventional protein sources. In this context, wheat flour was enriched with varying levels (5, 10, 15, 20 and 25%) of sesame protein isolates (SPI). Flour blends were used to prepare protein enriched muffins that were further evaluated for chemical composition, gross energy, color & textural analysis, and sensorial appraisal. The results were quite conclusive that nutritional quality of the muffins was improved with addition of SPI. Moreover, color analysis showed decreasing trend for L* & b* value, chroma and hue angle, while increasing trend was noticed for a* value. Likewise, the texture profile of muffins showed that firmness increased while elasticity decreased with gradual increase in protein contents. Sensory evaluation showed that muffins containing 15% SPI were rated better by the trained panelists. Conclusively, owing to high nutritive value and balanced nutritional profile, the use of sesame protein isolates can be handy tool to improve the nutritional quality of wheat based bakery products. These protein enriched products i.e. muffins can also help to fulfill the nutritional requirements of masses especially in developing countries.

Background: The purpose of this study was to examine the association between health belief model (HBM) constructs and a modified version of diet quality index in Iranian adolescents. Methods: One thousand and fifty five adolescents aged 13-15 years old completed this cross-sectional study. Participants were selected from secondary schools in Shiraz, one of the megacities of Iran, using stratified random sampling. A modified version of revised children’s diet quality index (M-RCDQI), was calculated for each adolescents and its association with the model construct was assessed using linear regression. Results: Mean M-RCDQI score was 58.91±8.58 out of the total of 90 points. Among the M-RCDQI components, the worse scores were obtained by dairy intake, dietary fiber and vegetables in which less than 20% of the students reached maximum score. Among HBM constructs, cues to action (B=0.194, p=0.003) and self-efficacy (B=0.04, p=0.007) had positive, significant association with adolescents’ diet quality. Also there was a positive, significant association between cues to action and fruits consumption (B=0.026, P=0.026), and a negative significant association was seen between cues to action and total fat intake (B=-0.629, p=0.021). Furthermore, self-efficacy had a direct significant association with dairy intake. Conclusion: M-RCDQI could be a suitable tool for assessment of diet quality index and it is recommended for use in further studies in similar populations. Cues to action and self-efficacy would both be effective mediators in improvement of nutritional behavior among adolescents.

Obesity is one of the most common nutritional disorders. Some studies suggest that obesity may be related to eating patterns, such as meal frequency, temporal distribution of eating events during the day, meal skipping and the frequency of out of meals. Therefore, in this cross-sectional study was investigated the relationships between meal frequency, anthropometric measurements, energy-macro/micronutrient intakes and meal skipping frequency for 1829 volunteer (520 men, 1309 women) adults aged between 40 and 64 years old, from Ankara, Turkey. The median meal frequency of women and men were 4 and 3, respectively. Approximately 57% of men and 61% of women have skipped meals and 76.8% of them were skipped their lunch. The meal frequency positively correlated with waist/ hip ratio in women (p<0.05). Additionally, there were positively significant correlations between meal frequency and saturated fatty acids, fiber, vitamin A, tiamine, riboflavin, folate, vitamin B6, vitamin C, calcium, magnesium, iron and copper intake (p<0.05). As a conclusion, the data indicate that increased meal frequency may have a beneficial effect on micronutrients intakes and some anthropometric measurements among adults.

Background: Cardiovascular diseases (CVD) are among the most common complications of diabetes. Lipid abnormalities in diabetic patients are not only related to higher risk of CVD, but also accelerate the progression of diabetic nephropathy. To the best of our knowledge, there is no study that has assessed the effects of probiotic soy milk on lipid profile in type 2 diabetic patients with nephropathy. Objective: The current study was designed to examine the effects of consumption of soy milk containing lactobacillus plantarum A7 compared with conventional soy milk on lipid panel in type 2 diabetic patients with nephropathy. Methods: A total of 44 type 2 diabetic patients with nephropathy were randomly assigned to receive 200 ml/day of either probiotic soy milk (n=22) or conventional soy milk (n=22) for eight weeks, in this randomized double-blind clinical trial. Fasting blood samples were taken at the beginning and after eight weeks of the intervention for analysis of lipid profile and other relevant variables. P values < 0.05 were considered as statistically significant. Results: Consumption of probiotic soy milk for 8 weeks led to an increase in serum genistein (17.6±15.3 vs. 4.5±2.3, p=0.002) and eGFR (15.9±10.8 vs. 3.2±8.4, p<0.001) compared with conventional soy milk. Additionally probiotic soy milk resulted in decreased LDL-cholesterol (-9.2±10.4 vs. -2.2±5.2, p=0.01), total cholesterol (-12.4±4.8 vs. -4.87±14.7, p=0.04), non-HDL cholesterol (-15.3±4.5 vs. -5.9±14.7, p=0.01) and serum TG (-14.6±12.5 vs. -3.9±9.3, p=0.007) compared with control group. We did not detect any significant effect of probiotic soy milk on serum HDL-cholestrol (1.11±3.38 vs. 0.90±2.7, p=0.8) and serum phosphorus (-0.14±0.10 vs. 0.05±0.5, p=0.1). Conclusion: Administration of soy milk containing lactobacillus plantarum A7 in type 2 diabetic patients with nephropathy had beneficial effects on lipid profile and glomerular function, but did not affect HDL-cholesterol. In addition probiotic soy milk did not result in a significant elevation in the serum phosphorus concentration. This trial was registered at http://www.irct.ir as IRCT201601027479N2.
背景:心血管疾病是糖尿病最常见的并发症之一。糖尿病患者血脂异常不仅与CVD发生风险增高有关，而且还会加速糖尿病肾病的进展。据我们所知，目前还没有研究评估益生菌豆浆对2型糖尿病肾病患者血脂的影响。目的:本研究旨在比较食用含有植物乳杆菌A7的豆浆与普通豆浆对2型糖尿病肾病患者脂质面板的影响。方法:在随机双盲临床试验中，44例2型糖尿病肾病患者被随机分配为200 ml/天的益生菌豆浆(n=22)或常规豆浆(n=22)，为期8周。在干预开始时和干预八周后采集空腹血样，分析血脂和其他相关变量。P值< 0.05认为有统计学意义。结果:与常规豆浆相比，饮用益生菌豆浆8周后血清染料木素(17.6±15.3比4.5±2.3,p=0.002)和eGFR(15.9±10.8比3.2±8.4,p<0.001)升高。此外，与对照组相比，益生菌豆浆降低了低密度脂蛋白胆固醇(-9.2±10.4比-2.2±5.2,p=0.01)、总胆固醇(-12.4±4.8比-4.87±14.7,p=0.04)、非高密度脂蛋白胆固醇(-15.3±4.5比-5.9±14.7,p=0.01)和血清TG(-14.6±12.5比-3.9±9.3,p=0.007)。我们未发现益生菌豆浆对血清高密度脂蛋白胆固醇(1.11±3.38 vs 0.90±2.7,p=0.8)和血清磷(-0.14±0.10 vs 0.05±0.5,p=0.1)有显著影响。结论:2型糖尿病肾病患者服用植物乳杆菌A7豆浆对其血脂和肾小球功能有改善作用，但对hdl -胆固醇无影响。此外，益生菌豆浆没有导致血清磷浓度的显著升高。该试验在http://www.irct.ir注册，注册号为IRCT201601027479N2。
