Screening of Mutagenicity of Some Food Snacks Retailed on the Lebanese Market Usage of food additives has become more and more frequent. Possible incorporation of genotoxic chemicals in dietary products, especially in food snacks, urges the need for their assessment. A total of 127 samples of food snacks, retailed on the Lebanese market, were screened for mutagenic activity towards Salmonella typhimurium strains TA98 and TA100 using Muta-ChromoPlate assay. The food items fall into two separate categories: the first category abides by high standards internationally approved; the second category is of a lower cost and a general poor quality. The first category was found to show no mutagenic activity even after exogenous S9- mix activation. However, 35.8% of the second category samples exhibited mutagenicity at 99% of significance, although without metabolic activation. These alarming results imply that drastic measures should be undertaken in order to protect the Lebanese consumers from being exposed to a potential risk of mutagenicity induced by such a dietary source.
黎巴嫩市场上零售的一些食品零食的致突变性筛选食品添加剂的使用越来越频繁。可能在膳食产品中,特别是在食品零食中掺入基因毒性化学物质,迫切需要对其进行评估。采用突变色板法对黎巴嫩市场零售的127份食品零食样品进行鼠伤寒沙门菌TA98和TA100诱变活性筛选。食品项目分为两类:第一类符合国际认可的高标准;第二类是成本较低但质量一般较差的。第一类被发现即使在外源S9-混合物激活后也没有诱变活性。然而,35.8%的第二类样品显示突变性,显着性为99%,尽管没有代谢激活。这些令人震惊的结果表明,应采取严厉措施,以保护黎巴嫩消费者免受这种饮食来源引起的潜在诱变风险。

Eating Disorders, Exercise Dependence and Body Image Dissatisfaction in Female Age Group Ironman Triathletes The purpose of this study was to investigate the prevalence of eating disorders, body image dissatisfaction and exercise dependency in female age group Ironman triathletes. A cross sectional examination was performed to determine whether the difference between preferred or aversive body type (somatotype), was associated with more prevalent eating disorder, body image dissatisfaction, and exercise addiction. Relationships between preferred/aversive somatotype and eating disorders, body image dissatisfaction and exercise dependency were explored. Data was collected from female age-group triathletes at the 2012 Ironman Arizona Triathlon. Body image dissatisfaction, eating disorders and exercise dependency were assessed via electronic capture questionnaires.

Antioxidant Activity of the Leaf Volatile Oil and Extracts of Olea europaea L.cv. Chetoui from Northern Tunisia This study is designed to examine the chemical composition and the in vitro antioxidant activity of the volatile oil and the extracts (polar and non-polar sub-fractions) of the methanol extract of Olea europea L. (cv) chetoui. GC and GC–MS analyses of the volatile oil from the dried leaves of the variety chetoui resulted in the identification of 32 compounds, representing 92.1% of the oil; alcohols (39.5%), aldehydes (19.1%) and ketones (12.2%) were the main groups of volatiles in the studied cultivar, comprising 70.8% of the total oil. Antioxidant activities of the samples were determined by the test system namely DPPH. The weakest radical scavenging activity was exhibited by the volatile oil (49.92%). Antioxidant activity of the non-polar sub-fraction of methanol extract was superior to the all samples tested with an inhibition of the free radical DPPH value of 64.31%. Total phenolic content of the polar and non-polar sub-fractions was 65.35 and 69.17 mg/100 g DW, respectively. In fact, the results showed no significant differences in the levels of polyphenols between sub-fractions of the methanol extract of Olea europea L. Furthermore, the amount of the total orthodiphenols was highest in the non-polar sub-fraction (219.66 mg /100 g DW).
油橄榄叶挥发油及提取物的抗氧化活性研究。本研究旨在研究欧洲油橄榄(Olea europea L., cv) Chetoui甲醇提取物的挥发油和提取物(极性和非极性亚组分)的化学成分和体外抗氧化活性。经气相色谱和气相色谱-质谱分析,鉴定出32种化合物,占总挥发油的92.1%;挥发物主要为醇类(39.5%)、醛类(19.1%)和酮类(12.2%),占挥发油总量的70.8%。采用DPPH测试系统测定样品的抗氧化活性。其中挥发油的自由基清除能力最弱,为49.92%。甲醇提取物非极性亚组分的抗氧化活性优于所有样品,其对自由基DPPH的抑制值为64.31%。极性亚组分和非极性亚组分的总酚含量分别为65.35和69.17 mg/100 g DW。结果表明,油橄榄甲醇提取物各组分间多酚含量差异不显著,而非极性组分中总正二酚含量最高(219.66 mg /100 g DW)。

The Biggest Problem we Face in the US: Obesity Studies show 70% of the US population is either overweight or obese. These staggering numbers have shot up since the non/low fat revolution where sadly sugar intake has doubled. For the first time in history, our children (the next generation) will not out live the current generation. 35% of our children are now overweight and this number grows daily. Studies also show over 600,000 people die a month in this country due to heart disease, cancer and diabetes. I have been a bodybuilder for 33 years and always had a passion for a healthy lifestyle.
我们在美国面临的最大问题:肥胖研究表明,70%的美国人要么超重,要么肥胖。自从非/低脂肪革命以来,这些惊人的数字急剧上升,可悲的是,糖的摄入量翻了一番。历史上第一次,我们的孩子(下一代)不会比这一代人活得久。现在有35%的儿童超重,而且这个数字每天都在增长。研究还显示,这个国家每月有超过60万人死于心脏病、癌症和糖尿病。我做了33年的健美运动员,一直热衷于健康的生活方式。

Role of pH in the Mutagenicity of Aflatoxin B1 in Maize Tortillas during In Vitro Human Digestion Model Aflatoxins (AFs) are potent mutagens, carcinogens and teratogens for humans; thus their presence in food is of great concern. A maize tortilla survey in Mexico revealed that 17% are contaminated with AFs. The initial process to prepare tortillas includes boiling maize grains with lime and to assumpt that AFs in maize tortillas are destroyed, protecting consumers from their mutagenic effects.The purpose of this study was to investigate the mutagenicity of aflatoxin B1 (AFB1) in tortillas during digestion.
黄曲霉毒素(AFs)是人类的强诱变剂、致癌物和致畸物。因此,它们在食物中的存在是非常值得关注的。墨西哥的一项玉米饼调查显示,17%的玉米饼被AFs污染。准备玉米饼的最初过程包括用石灰煮玉米谷物,并假设玉米饼中的AFs被破坏,保护消费者免受其诱变作用。本研究的目的是研究黄曲霉毒素B1 (AFB1)在玉米饼消化过程中的诱变性。

Modeling of Time Dependent Variation of Moisture Content, Density, Porosity and Specific Volume during Drying of Apple and Potato In this work, drying experiments were conducted for one variety of apple (Fuji) and three varieties of potato, namely, Kufri Chipsona-1, Kufri Himsona and Kufri Bahar at temperature 60, 70 and 80oC in the tray dryer. The effect of temperature on drying characteristics and quality parameters of the dried apple and potato slices was determined. For investigating the drying characteristics of apple and potato, an appropriate drying model was presented by modifying existing drying model. A non-linear regression procedure was employed to fit several drying models available in the literature to the experimental data. The models were compared according to chi-square ( χ 2 ), coefficient of determination ( R2 ) and root mean square error (RMSE). Results based on our model had close resemblance with experimental observations. Drying constant was correlated with temperature by using exponential equation.
苹果和马铃薯干燥过程中水分含量、密度、孔隙率和比容随时间变化的建模本研究对1个苹果品种(富士)和3个马铃薯品种(库夫里Chipsona-1、库夫里Himsona和库夫里Bahar)在60、70和80℃的托盘干燥机中进行了干燥试验。研究了温度对干苹果、干马铃薯片干燥特性及品质参数的影响。为研究苹果和马铃薯的干燥特性,在对现有干燥模型进行修正的基础上,提出了合适的干燥模型。采用非线性回归方法对文献中几种干燥模型与实验数据进行拟合。根据χ 2、决定系数R2和均方根误差(RMSE)对模型进行比较。模型的计算结果与实验结果非常接近。用指数方程将干燥常数与温度联系起来。

The Influence of NaCl Salinity on the Physiology and Quality of Four Cherry Tomato Fruits The aim of the present work was to study the effects of increasing salinity (0, 75 and 150 mM) on the physiological (i.e. respiration, and emission of ethylene) and quality parameters (i.e. TSS, pH, acidity, ascorbic acid, dry matter, soluble sugars, sweetness index, lycopene and colour) of four ‘cherry’ tomato hybrids widely used in Greece (i.e. Cherelino F1, Scintilla F1, Delicassi F1, and Zucchero F1). The focus on salinity can be explained by the fact that it is a major environmental stress, especially in arid and semi-arid regions like the Mediterranean ones. To observe the effects of salinity, οne month old seedlings of uniform size plants were grown in a greenhouse in 12.0 L pots filled with a mixture of loamy soil and perlite (3:1 v/v) from April to July 2012. All fruits were harvested at their full ripening stage and, then, sorted into marketable and unmarketable fruits. Random samples of the marketable fruits were used to determine the physiological and quality parameters.
NaCl盐度对四种樱桃番茄果实生理和品质的影响本研究的目的是研究盐度增加(0、75和150 mM)对希腊广泛使用的四种樱桃番茄杂交品种(Cherelino F1、Scintilla F1、Delicassi F1和Zucchero F1)的生理(即呼吸和乙烯排放)和品质参数(即TSS、pH、酸度、抗坏血酸、干物质、可溶性糖、甜味指数、番茄红素和颜色)的影响。对盐度的关注可以用以下事实来解释:盐度是一个主要的环境压力,尤其是在地中海等干旱和半干旱地区。2012年4月至7月,在温室中以12.0 L的盆栽为材料,用壤土和珍珠岩的混合物(3:1 v/v)填充,培养1个月龄、大小均匀的植株。所有的水果都是在完全成熟的阶段收获的,然后分为可销售和不可销售的水果。采用随机抽样的方法,测定了其生理和品质参数。

The focus on salinity can be explained by the fact that it is a major environmental stress, especially in arid and semi-arid regions like the Mediterranean ones. To observe the effects of salinity, οne month old seedlings of uniform size plants were grown in a greenhouse in 12.0 L pots filled with a mixture of loamy soil and perlite (3:1 v/v) from April to July 2012.

An Area at War: Alarming Malnutrition Status and its Predictors among Children Aged 6-60 Months Old in Kokang, Myanmar Aim: Myanmar is a populous and impoverished country with military conflicts for over 40 years and Kokang is one of the most turbulent regions. Malnutrition is a major health problem in this area, however researches are limited. This study aims to evaluate the malnutrition condition of children in Kokang, Myanmar and the factors associated with malnutrition. Methods: Data were obtained from 123 children aged from 6 to 60 months. Anthropometrical assessment was performed and validated questionnaires were used to collect socioeconomic and demographic data. Results: Among the children enrolled in this study, 42.5% were found to be stunting, 22.5% were underweight, 8.3% were wasting, 8.3% were thin, 5.9% had a small head circumference, and 3.3% were wasting with amid-upper arm circumference <12.5 cm. Drinking spring or river water (OR=7.11, 95% CI2.46–20.52) was a predictor of stunting and low family annual income contributed to underweight (OR=8.95, 95% CI 1.63–49.11) in the regression model. Predictors of wasting included age and length of exclusive breastfeeding. Conclusion: This study illustrates the alarming local prevalence of childhood malnutrition and the associated predictors, which require a multipronged approach to find a solution.
目的:缅甸是一个人口众多的贫困国家,军事冲突持续了40多年,果敢是最动荡的地区之一。营养不良是这一领域的主要健康问题,但研究有限。本研究旨在评估缅甸果敢地区儿童的营养不良状况及与营养不良有关的因素。方法:收集6 ~ 60月龄儿童123例资料。进行了人体测量评估,并使用有效的问卷来收集社会经济和人口统计数据。结果:42.5%的儿童发育迟缓,22.5%的儿童体重不足,8.3%的儿童消瘦,8.3%的儿童消瘦,5.9%的儿童头围小,3.3%的儿童消瘦,上臂中围<12.5 cm。在回归模型中,饮用泉水或河水(or =7.11, 95% CI2.46 ~ 20.52)是发育迟缓的预测因子,家庭年收入低是体重不足的预测因子(or =8.95, 95% CI 1.63 ~ 49.11)。消瘦的预测因素包括年龄和纯母乳喂养的时间。结论:本研究表明,当地儿童营养不良的发生率及其相关预测因素令人担忧,需要采取多管齐下的方法来寻找解决方案。
