    Respiration of sugars by non-Saccharomyces yeasts has been recently proposed for lowering alcohol levels in wine. Development of industrial fermentation processes based on such an approach requires, amongst other steps, the identification of yeast strains which are able to grow and respire under the relatively harsh conditions found in grape must. This work describes the characterization of a collection of non-Saccharomyces yeast strains in order to identify candidate yeast strains for this specific application. It involved the estimation of respiratory quotient (RQ) values under aerated conditions, at low pH and high sugar concentrations, calculation of yields of ethanol and other relevant metabolites, and characterization of growth responses to the main stress factors found during the first stages of alcoholic fermentation. Physiological features of some strains of Metschnikowia pulcherrima or two species of Kluyveromyces, suggest they are suitable for lowering ethanol yields by respiration. The unsuitability of Saccharomyces cerevisiae strains for this purpose was not due to ethanol yields (under aerated conditions they are low enough for a significant reduction in final ethanol content), but to the high acetic acid yields under these growth conditions. According to results from controlled aeration fermentations with one strain of M. pulcherrima, design of an aeration regime allowing for lowering ethanol yields though preserving grape must components from excessive oxidation, would be conceivable.

    Because childhood obesity is such a threat to the physical, mental, and social health of youth, there is a great need to identify effective strategies to reduce its prevalence. The objective of this study was to estimate the mean calories from added sugars that are saved by switching sugar-sweetened beverages (including soda, fruit-flavored drinks, and sport drinks) and flavored milks consumed to unflavored low-fat milk (calories from added sugars both at and away from school. Overall, these changes translated to a mean of 205 calories or a 10% savings in energy intake across all students (8% among children in elementary school and 11% in middle and high schools). Eighty percent of the daily savings were attributed to beverages consumed away from school, with results consistent across school level, sex, race/ethnicity, and weight status. Children's consumption of sugar-sweetened beverages at home contributed the greatest share of empty calories from added sugars. Such findings indicate that parental education should focus on the importance of reducing or eliminating sugar-sweetened beverages served at home. This conclusion has implications for improving children's food and beverage environments for food and nutrition educators and practitioners, other health care professionals, policy makers, researchers, and parents.

    Full Text Available Summary. Was studied the technology of producing aerated candies "Souffle" with replacement of sugar to molasses with increased shelf life, molded by "jetting" with a vacuum syringe with continuous action, which is used in the meat industry, into metallized film type "flow-pack ". Studied the process of foaming disperse systems. Studied the process of gelation and gelation affected by various factors. To establish a relationship between the effective viscosity and jelly mass of gelation ability of agar were achieved the dependence according to the effective viscosity of the jelly mass shear rate and a shear rate on the shear stress at temperature of 65 ˚C and a mass fraction of solids of 78%. Viscosity reduction has a positive effect on the process of molding molasses candies by the "extrusion". Were definede values of the plastic strength of jelly masses and found that replacing sugar to molasses reduces the plastic strength, but it does not affect a good form-stable ability. Cinnamon was added into the prescription whipped composition to improve the nutritional value of products. Were defined organoleptic, physical and chemical qualities, calculated energy value of the products. High hygroscopic souffle on molasses requires hermetic packaging. Proposed a new progressive method of forming a souffle with a vacuum syringe with continuous action, which is used in the meat industry to form sausages. Curing and structure foarming implemented directly in the shell for 2 h, which is an important advantage of this method. Whipped products on molasses are functional.

    This study aimed to analyze 123 genotypes of Capsicum baccatum L. originating from 22 countries, at two stages of fruit development, for vitamin C content and its relationship with reducing sugars in fruit pericarp. Among the parametric population, vitamin C and reducing sugar concentrations ranged between 2.54 to 50.44 and 41-700mgg(-1) DW of pericarp, respectively. Overall, 14 genotypes accumulated 50-500% of the RDA of vitamin C in each 2g of fruit pericarp on a dry weight basis. Compared with ripened fruits, matured (unripened) fruits contained higher vitamin C and lower reducing sugars. About 44% variation in the vitamin C content could be ascribed to levels of reducing sugars. For the first time, this study provides comprehensive data on vitamin C in the world collection of C. baccatum genotypes that could serve as a key resource for food research in future.

    Beverage taxes came into light with increasing concerns about obesity, particularly among youth. Sugar-sweetened beverages have become a target of anti-obesity initiatives with increasing evidence of their link to obesity. Our paper offers a method for estimating revenues from an excise tax on sugar-sweetened beverages that governments of various levels could direct towards obesity prevention. We construct a model projecting beverage consumption and tax revenues based on best available data on regional beverage consumption, historic trends and recent estimates of the price elasticity of sugar-sweetened beverage demand. The public health impact of beverage taxes could be substantial. An estimated 24% reduction in sugar-sweetened beverage consumption from a penny-per-ounce sugar-sweetened beverage tax could reduce daily per capita caloric intake from sugar-sweetened beverages from the current 190-200 cal to 145-150 cal, if there is no substitution to other caloric beverages or food. A national penny-per-ounce tax on sugar-sweetened beverages could generate new tax revenue of $79 billion over 2010-2015. A modest tax on sugar-sweetened beverages could both raise significant revenues and improve public health by reducing obesity. To the extent that at least some of the tax revenues get invested in obesity prevention programs, the public health benefits could be even more pronounced. Copyright © 2011 Elsevier Inc.

    In the present investigation, the changes in sucrose, reducing and total sugar content due to water-deficit stress in rice leaves were modeled using visible, near infrared (VNIR) and shortwave infrared (SWIR) spectroscopy. The objectives of the study were to identify the best vegetation indices and suitable multivariate technique based on precise analysis of hyperspectral data (350 to 2500 nm) and sucrose, reducing sugar and total sugar content measured at different stress levels from 16 different rice genotypes. Spectral data analysis was done to identify suitable spectral indices and models for sucrose estimation. Novel spectral indices in near infrared (NIR) range viz. ratio spectral index (RSI) and normalised difference spectral indices (NDSI) sensitive to sucrose, reducing sugar and total sugar content were identified which were subsequently calibrated and validated. The RSI and NDSI models had R2 values of 0.65, 0.71 and 0.67; RPD values of 1.68, 1.95 and 1.66 for sucrose, reducing sugar and total sugar, respectively for validation dataset. Different multivariate spectral models such as artificial neural network (ANN), multivariate adaptive regression splines (MARS), multiple linear regression (MLR), partial least square regression (PLSR), random forest regression (RFR) and support vector machine regression (SVMR) were also evaluated. The best performing multivariate models for sucrose, reducing sugars and total sugars were found to be, MARS, ANN and MARS, respectively with respect to RPD values of 2.08, 2.44, and 1.93. Results indicated that VNIR and SWIR spectroscopy combined with multivariate calibration can be used as a reliable alternative to conventional methods for measurement of sucrose, reducing sugars and total sugars of rice under water-deficit stress as this technique is fast, economic, and noninvasive.

    To test the efficacy of nutritional guidelines for school lunch cooks aiming to reduce added sugar in school meals and their own sugar intake. A controlled randomized cluster trial was carried out in twenty public schools in the municipality of Niteroi in Rio de Janeiro, Southeastern Brazil, from March to December 2007. A nutrition educational program was implemented in the schools in question through messages, activities and printed educational materials encouraging reduced levels of added sugar in school meals and in the school lunch cooks' own intake. The reduced availability of added sugar in schools was evaluated using spreadsheets including data on the monthly use of food item supplies. The cooks' individual food intake was evaluated by a Food Frequency Questionnaire. Anthropometric measurements were taken according to standardized techniques and variation in weight was measured throughout the duration of the study. There was a more marked reduction in the intervention schools compared to the control schools (-6.0 kg versus 0.34 kg), but no statistically significant difference (p = 0.21), although the study power was low. Both groups of school lunch cooks showed a reduction in the consumption of sweets and sweetened beverages, but the difference in sugar intake was not statistically significant. Weight loss and a reduction in total energy consumption occurred in both groups, but the difference between them was not statistically significant, and there was no alteration in the percentages of adequacy of macronutrients in relation to energy consumption. The strategy of reducing the use and consumption of sugar by school lunch cooks from public schools could not be proved to be effective.

    Tubers of Russet Burbank potatoes from 0, 181.8 and 363.6 kg/ha nitrogen were irradiated with 0, 0.05, 0.1 and 0.2 kGy of gamma rays (Co 60 source) and stored for three months at temperatures of 10 and 15.5°C. Changes in reducing sugars and sucrose contents were significantly influenced by nitrogen and irradiation levels while storage temperatures had no significant effect. Nitrogen and irradiation significantly decreased reducing and non-reducing sugars while temperature had no significant effect. Reducing sugars decreased with increasing levels of nitrogen and irradiation. Tubers from zero fertilizer regime developed 1.5% reducing sugars. Irradiation at 0.2 kGy dosage decreased reducing sugars from 1.7 to 0.9%. The breakdown of non-reducing sugars increased with increasing nitrogen levels but decreased with irradiation. Tubers from the maximum nitrogen plot had a 36% decrease of non-reducing sugars. Irradiation at 0.1 kGy dosage had the least change (4.9% decrease) of non-reducing sugars. (author)

    Only a quarter of adults and 7% of children consume recommended amounts of vegetables each day. Often vegetables are not initially palatable due to bitterness, which may lead children and adults to refuse to taste or eat them. The objective of this research was to determine if very small amounts of sugar or salt (common household ingredients) could lead to significant reductions in bitterness intensity and increased hedonic ratings of green vegetable purees. For Experiment 1, three different green vegetable purees (broccoli, spinach, and kale) were prepared with different levels of sugar (0%, 0.6%, 1.2%, and 1.8%) or salt (0 and 0.2%). Samples were evaluated using standard descriptive analysis techniques with nine adults who completed more than 20 h of green vegetable specific training as a group. For Experiment 2, each vegetable puree was prepared with either 0% or 2% sugar, and bitterness was assessed via a forced choice task with 84 adults. For Experiment 3, each vegetable puree was prepared with 0%, 1%, or 2% sugar and rated for liking on standard 9 point hedonic scales by 99 adults. Experiments 1 and 2 showed that addition of small amounts of sugar and salt each reduced the bitterness (and increased sweetness and saltiness) from all three vegetables without altering other sensory properties (e.g. texture or aroma). Experiment 3 showed that adding sugar to vegetable purees increased hedonic ratings for adult consumers. We also found parents had mixed attitudes about the idea of adding sugar to foods intended for infants and toddlers. Further research on the effects of bitterness masking especially for specific populations (e.g., infants and young children or adults who have higher sensitivity to bitter taste) is warranted.

    This study aimed to gain an in-depth understanding of children's perceptions of sugar-sweetened beverages (SSBs). Nine focus groups were conducted in grade 5 and 6 elementary schoolchildren. Nine urban and rural elementary schools in London, Ontario, Canada. Fifty-one children, 58% of which were male, 52% of whom were in grade 5, and 84% of whom were Caucasian. Children's views on sugar-sweetened beverages. Three researchers conducted inductive content analysis on the data independently using the principles of the immersion-crystallization method. Participants had a high level of awareness of beverages and their health effects, which was primarily targeted at the sugar content. Dominant factors that influenced children's beverage choices and consumption patterns included taste, parental control practices, accessibility, and advertising. Participants identified a wide array of strategies to reduce SSB consumption in children, including educational strategies for both children and parents and policy-level changes at both the government and school levels. Despite a high level of awareness of SSBs, children believed that further education and policies regarding SSBs were warranted. These data may prove helpful in designing effective interventions targeted at children and parents to reduce SSB consumption by children.

    Reassimilation of internal CO 2 via woody tissue photosynthesis has a substantial effect on tree carbon income and wood production. However, little is known about its role in xylem vulnerability to cavitation and its implications in drought-driven tree mortality. Young trees of Populus nigra were subjected to light exclusion at the branch and stem levels. After 40 d, measurements of xylem water potential, diameter variation and acoustic emission (AE) were performed in detached branches to obtain acoustic vulnerability curves to cavitation following bench-top dehydration. Acoustic vulnerability curves and derived AE 50 values (i.e. water potential at which 50% of cavitation-related acoustic emissions occur) differed significantly between light-excluded and control branches (AE 50,light-excluded  = -1.00 ± 0.13 MPa; AE 50,control  = -1.45 ± 0.09 MPa; P = 0.007) denoting higher vulnerability to cavitation in light-excluded trees. Woody tissue photosynthesis represents an alternative and immediate source of nonstructural carbohydrates (NSC) that confers lower xylem vulnerability to cavitation via sugar-mediated mechanisms. Embolism repair and xylem structural changes could not explain this observation as the amount of cumulative AE and basic wood density did not differ between treatments. We suggest that woody tissue assimilates might play a role in the synthesis of xylem surfactants for nanobubble stabilization under tension. © 2017 The Authors.

    Sugars affect central aspects of plant physiology, including photosynthesis, stomatal behavior and the loss of water through the stomata. Yet, the potential effects of sugars on plant aquaporins (AQPs) and water conductance have not been examined. We used database and transcriptional analyses, as well as cellular and whole-plant functional techniques to examine the link between sugar-related genes and AQPs. Database analyses revealed a high level of correlation between the expression of AQPs and that of sugar-related genes, including the Arabidopsis hexokinases 1 (AtHXK1). Increased expression of AtHXK1, as well as the addition of its primary substrate, glucose (Glc), repressed the expression of 10 AQPs from the plasma membrane-intrinsic proteins (PIP) subfamily (PIP-AQPs) and induced the expression of two stress-related PIP-AQPs. The osmotic water permeability of mesophyll protoplasts of AtHXK1-expressing plants and the leaf hydraulic conductance of those plants were significantly reduced, in line with the decreased expression of PIP-AQPs. Conversely, hxk1 mutants demonstrated a higher level of hydraulic conductance, with increased water potential in their leaves. In addition, the presence of Glc reduced leaf water potential, as compared with an osmotic control, indicating that Glc reduces the movement of water from the xylem into the mesophyll. The production of sugars entails a significant loss of water and these results suggest that sugars and AtHXK1 affect the expression of AQP genes and reduce leaf water conductance, to coordinate sugar levels with the loss of water through transpiration. © 2017 The Authors The Plant Journal © 2017 John Wiley & Sons Ltd.

    Full Text Available The objective of this work was to study the acid and enzymatic hydrolysis of cassava bagasse for the recovery of reducing sugars and to establish the operational costs. A statistical program "Statistica", based on the surface response was used to optimize the recovery of reducing sugars in both the processes. The process economics was determined considering the values of reducing sugars obtained at laboratory scale, and the operations costs of a cylindrical reactor of 1500 L, with flat walls at the top and bottom. The reactor was operated with 150 kg of cassava bagasse and 1350 kg of water. The yield of the acid hydrolysis was 62.4 g of reducing sugars from 100 g of cassava bagasse containing 66% starch. It represented 94.5% of reducing sugar recovery. The yield of the enzymatic hydrolysis was 77.1 g of reducing sugars from 120 g of cassava bagasse, which represented 97.3% of reducing sugars recovery. Concerning to the time, a batch of acid hydrolysis required 10 minutes, plus the time to heat and cool the reactor, and a batch of the enzymatic hydrolysis needed 25 hours and 20 minutes, plus the time to heat and to cool the reactor. Thus, the acid hydrolysis of 150 kg of cassava bagasse required US$ 34.27, and the enzymatic hydrolysis of the same amount of cassava bagasse required US$ 2470.99.

    Nectar-feeding animals have among the highest recorded metabolic rates. High aerobic performance is linked to oxidative damage in muscles. Antioxidants in nectar are scarce to nonexistent. We propose that nectarivores use nectar sugar to mitigate the oxidative damage caused by the muscular demands of flight. We found that sugar-fed moths had lower oxidative damage to their flight muscle membranes than unfed moths. Using respirometry coupled with δ 13 C analyses, we showed that moths generate antioxidant potential by shunting nectar glucose to the pentose phosphate pathway (PPP), resulting in a reduction in oxidative damage to the flight muscles. We suggest that nectar feeding, the use of PPP, and intense exercise are causally linked and have allowed the evolution of powerful fliers that feed on nectar.

    2014-01-01

    Objectives. We estimated the effect of a simulated cap-and-trade policy to reduce added sugar in the food supply. Methods. Using nationally representative data on added-sugar content and consumption, we constructed a mathematical model of a cap-and-trade policy and compared its health implications to those of proposals to tax sugar sweetened beverages or added sugars. Results. Capping added-sugar emissions into the food supply by food manufacturers at a rate of 1% per year would be expected to reduce the prevalence of obesity by 1.7 percentage points (95% confidence interval [CI] = 0.9, 2.4; a 4.6% decline) and the incidence of type 2 diabetes by 21.7 cases per 100 000 people (95% CI = 12.9, 30.6; a 4.2% decline) over 20 years, averting approximately $9.7 billion in health care spending. Racial and ethnic minorities would be expected to experience the largest declines. By comparison, equivalent price penalties through excise taxes would be expected to generate smaller health benefits. Conclusions. A cap-and-trade policy to reduce added-sugar intake may reduce obesity and type 2 diabetes to a greater extent than currently-proposed excise taxes. PMID:25365146

    The objective of this study was to obtain insight into the actual effectiveness of lowering reducing sugars concentration in par-fried potato strips on the concentration and variation of acrylamide in French fries prepared in real-life situations in food service establishments. Acrylamide, frying time, frying temperature, and reducing sugars were measured and characteristics of fryers were recorded. Data showed that the use of par-fried potato strips with lower concentrations of reducing sugars than the commonly used potato strips was an effective measure to reduce acrylamide concentrations in French fries prepared under standardised frying conditions. However, there was still large variation in the acrylamide concentrations in French fries, although the variation in reducing sugars concentrations in low and normal types of par-fried potato strips was very small and the frying conditions were similar. Factors that could affect the temperature-time profile of frying oil were discussed, such as setting a lower frying temperature at the end than at the start of frying, product/oil ratio and thawing practice. These need to be controlled in daily practice to reduce variation in acrylamide. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Full Text Available An investigation was carried out to develop lassi from sour dahi using different levels of sugar (10, 15, 20 and 25% and 15% water. Lassi quality was assayed through the study of physical, chemical and microbiological parameters. Results revealed that significant difference existed in overall physical score of lassi samples and the highest score was found in 15% sugar lassi whereas, the lowest score was found in 25% sugar lassi. Total solids, carbohydrate, fat, protein and ash contents differed significantly among various levels of sugar added lassi. From chemical test, it appears that, 15% sugar added lassi possess the highest fat and protein values whereas, the highest total solids and carbohydrate values posses in 25% sugar added lassi. No significant difference (p>0.05 revealed in terms of pH value and acidity percentage among lassi types. Lassi made from 10% sugar was most inferior than other levels of sugar added lassi in respect of microbiological quality- total viable count (×104 cfu/mL content was 95.67±2.08 and coliform (×10 cfu/mL content was 1.00±0.00. Considering above mentioned quality aspects, it might be resolved that lassi could be prepared successfully from sour dahi with 15% sugar keeping water level constant at 15%.

    2016-01-01

    Individuals who adhere to reduced-sodium diets come to prefer less salt over time, but it is unclear whether sweet taste perception is modulated by reduced sugar intake. The objective was to determine how a substantial reduction in dietary intake of simple sugars affects sweetness intensity and pleasantness of sweet foods and beverages. Healthy men and women aged 21-54 y participated for 5 mo. After the baseline month, 2 subject groups were matched for demographic characteristics, body mass index, and intake of simple sugars. One group (n = 16; 13 of whom completed key experimental manipulations) was randomly assigned to receive a low-sugar diet during the subsequent 3 mo, with instructions to replace 40% of calories from simple sugars with fats, proteins, and complex carbohydrates. The other (control) group (n = 17; 16 of whom completed the study) did not change their sugar intake. During the final month, both groups chose any diet they wished. Each month subjects rated the sweetness intensity and pleasantness of vanilla puddings and raspberry beverages that varied in sucrose concentration. ANOVA showed no systematic differences between groups in rated sweetness during the baseline or first diet month. During the second diet month, the low-sugar group rated low-sucrose pudding samples as more intense than did the control group (significant group-by-concentration interaction, P = 0.002). During the third diet month, the low-sugar subjects rated both low and high concentrations in puddings as ∼40% sweeter than did the control group (significant effect of group, P = 0.01). A weaker effect on rated sweetness was obtained for the beverages. Rated pleasantness was not affected for either of the stimuli. This experiment provides empirical evidence that changes in consumption of simple sugars influence perceived sweet taste intensity. More work is needed to determine whether sugar intake ultimately shifts preferences for sweet foods and beverages. This trial was

    Full Text Available In commercial apiculture, beekepers usually remove honey from hives and replenish food reserves with sugar syrup. When honeybees use sugar syrup (sucrose solution, they break down sucrose into glucose and fructose. These processes exhaust and weaken bees. In order to prevent bee exhaustion resulting from this processing, bees should preferably be supplied with ready made food before winter, i.e., with syrup in which sucrose has already been inverted. Feeding with inverted syrups is the most popular way of honeybee feeding. Beekeepers usually prepare inverted syrups by adding a weak organic acid (citric, oxalic, acetic or lactic acid to sucrose solution at elevated temperatures. Inverted syrup production under uncontrolled pH, temperature and time conditions can cause the formation of 5-hydroxymethyl-2-furaldehyde (HMF, a compound harmful to bees. High quality inverted syrup can be obtained through the hydrolytic decomposition of sucrose by the enzyme invertase. Due to its invertase content, honey can be used as a biocatalyst for sucrose inversion. Invertase activity depends on the type, method and time of honey storage. This study evaluates the catalytic effect of acacia honey on formation of reducing sugars during hydrolysis of 50 wt.% sucrose solution. The ratio of reducing sugars and sucrose at 40°C, after 5 days of hydrolysis at a concentration of honey and 10 wt.% was 0.30 g reducing sugars/g of sucrose. The highest content of reducing sugars was achieved at a temperature of 35°C, after 48 h of invertion. In all samples of hydrolysates obtained at different temperatures (35–65°C, HMF was detected at concentrations of less than 4.32 mg kg–1. A high degree of negative correlation (coefficient of linearity –0.94 was established between parameters of volumetric and polarimetric measurements during the hydrolysis of sucrose.

    Full Text Available Due to problems in storage, transportation and price fluctuation of fresh potato, production of ready-to-use products like French fries is of particular importance. French fries quality mainly depends on the appearance, taste, color, texture and oil uptake. One of the important steps in product processing is blanching. This step improves product texture and color due to the decrease in reducing sugar content, and causes reduction of oil uptake due to the gelatinization of surface starch. Therefore, by selecting a suitable method and condition, the improvement of product quality is possible. In order to investigate the effect of blanching temperature on kinetic of the reducing sugar content and changes in potato stick color and texture, sticks with 0.8 0.8 8 cm dimensions were prepared and blanching was carried out with hot water at different temperatures (60, 70, 80 and 90°C and various times up to 120 minutes. Color, texture and reducing sugar content of samples were measured during blanching. The results showed that reducing sugar content was reduced during the blanching as a function of temperature and time. Also, product color and texture were mainly affected by blanching temperature, with the low temperature being more suitable to improve potato stick quality. According to the results, there was no significant difference between blanching at 80, 90°C and 60°C for reducing sugar content. Also, for this parameter, there was no significant difference between times of 100 and 5 minutes at 60°C. The least texture damage was obtained by blanching at 60°C in a short time. It could be concluded that to preserve potato stick color and texture and reduce energy consumption, blanching can be done at 60°C for 5 minutes if enzymes are inactivated.

    Full Text Available As the fossil energy decrease such as petroleum and natural gas, that are encourages a lot of research to develop new sources of energy from renewable raw materials. One of the source is through reducing sugar (glucose and xylose obtained from coffee pulp waste; this is due to abundant production of coffee pulp every year reaching 743 kg/ha. In addition, this waste has not been used optimally and the cellulose and hemicellulose content of the coffee is high. The purpose of this study is to get the optimal operating condition for reducing sugar production from coffee pulp waste. The method used for optimization is Response Surface Methodology with Central Composite Design. The optimum operation condition obtained was pH 4.63 at 34ºC for 16.29 hours of hydrolysis. As a result, the predicted yield gained was 0.147 grams of reducing sugars / gram of cellulose+hemicellulose. The result indicates the gained yield was 0.137 grams of reducing sugars / gram of cellulose+hemicellulose.

    The demand for zero and reduced-sugar food products containing cocoa is expanding continuously. The present study was designed to evaluate the feasibility of producing high-quality chocolate sweetened with a crude extract of Stevia rebaudiana (Bertoni) prepared by a green microwave-assisted water-steam extraction procedure. Seven approximately isosweet chocolate formulations were developed, mixing cocoa paste, sucrose, commercial stevioside, crude green extract and maltitol in different proportions. All samples were analyzed for the determination of polyphenol and flavonoid content, antioxidant activity, and sensory acceptability. The use of a crude stevia extract allowed low-sugar, high-quality chocolates to be obtained that were also acceptable by consumers and had a significant increased antioxidant activity. Moreover, consumers' segmentation revealed a cluster of consumers showing the same overall liking for the sample with 50% sucrose replaced by the stevia crude extract as that obtained with the commercial stevioside and the control sample (without sucrose replacement). The results provide information that can contribute to promoting the development of sweet food products, with advantages in terms of an improved nutritional value (reduced sugar content and increased antioxidant activity) and a reduced impact of the production process on the environment. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

  16. Evaluation of weed control methods on sugar beet (Beta vulgaris L. yield at different levels of nitrogen

    Full Text Available Introduction: Weed competition is one of the major factors which limit sugar beet production in the world. Weed – crop interactions are based on competition for water, nutrients and light and allelopathic effects may also play a small role. In sugar beet weed interference, all these factors are important too, but the light is of prime importance. Due to the fact that a lot of weeds can grow above the sugar beet canopy and reduce the amount of photosynthetic radiation reaching the crop, these weeds are stronger competitors compared to smaller weeds. In much sugar beet growing areas dicot weeds of the families Chenopodiaceae, Asteraceae, Brassicaceae and Polygonaceae are of major importance. The monocots are less important compared to dicot weeds. Competition from uncontrolled annual weeds that emerge within 8 weeks of sowing or within 4 weeks of the crop reaching the two-leaf stage can reduce root yields by 26–100% .Weeds that emerge 8 weeks after sowing, and particularly after the sugar beet plants have eight or more leaves, are less likely to affect yield. Although tractor hoeing and hand labour are still used in many production areas, herbicides have been the primary method of weed control in sugar beet. The effectiveness of pre-emergence residual herbicides decreases with reductions in rainfall or soil wet content. Therefore, less than 10 % of the total sugar beet crop is treated with pre-emergence herbicides. The remaining 90 % depends solely on a selection of post-emergence herbicides to maintain season-long weed control. The major herbicides are phenmedipham, chloridazon, metamitron. Mixtures of post-emergence, broad spectrum herbicides have to be applied to control the wide range of weed species in sugar beet crops. Materials and Methods: To study the effects of weeds control by hand weeding and herbicides combination with two selective herbicides at different levels of nitrogen application on sugar beet yield and quality

    Coconut husk wastes are abundantly available in Indonesia. It has a potential to be used into alternative renewable energy sources such as hydrogen using enzymatic hydrolysis followed by a fermentation process. Unfortunately, enzymatic hydrolysis is hampered by the complex structure of lignocellulose, so the cellulose component is hard to degrade. In this study, Combined Subcritical Water (SCW) and enzymatic hydrolysis are applied to enhance fermentable, thereby reducing production of sugar from coconut husk. There were two steps in this study, the first step was coconut husk pretreated by SCW in batch reactor at 80 bar and 150-200°C for 60 minutes reaction time. Secondly, solid fraction from the results of SCW was hydrolyzed using the mixture of pure cellulose and xylanase enzymes. Analysis was conducted on untreated and SCW-treated by gravimetric assay, liquid fraction after SCW and solid fraction after enzymatic hydrolysis using DNS assay. The maximum yield of reducing sugar (including xylose, arabinose glucose, galactose, mannose) was 1.254 gr per 6 gr raw material, representing 53.95% of total sugar in coconut husk biomass which was obtained at 150°C 80 bar for 60 minutes reaction time of SCW-treated and 6 hour of enzymatic hydrolysis using mixture of pure cellulose and xylanase enzymes (18.6 U /gram of coconut husk).

    The consumption of sugar is relatively high in Denmark - and other industrial countries - and many persons have a consumption which exceeds the recommended level of maximally 10% of energy intake. A high sugar consumption may reduce the nutrient density of the diet and increase the risk of vitamin...... and mineral deficiency, especially in low energy consumers. The sugar intake and the fat intake, expressed as percentage of energy, usually show an inverse association. This has lead to the statement that a diet with both a low sugar content and a low fat content is incompatible, but we will argue...... that this is not the fact. The significance of sugar for the development of obesity is not clarified. A high fat content in the diet seems to promote the development of obesity, while a high carbohydrate content tends to reduce obesity. It is not known if sugar in this connection is comparable to the other carbohydrates...

  19. Effectiveness of sugar-sweetened beverages taxes to reduce obesity: evidence brief for policy

    The high prevalence of obesity in Chile, along with the increasing consumption of sugary drinks in the country, has made apparent the need to propose fiscal measures, through taxes on specific foods, as a complementary alternative to approach this problem. Since 2014, an additional 5% increase in the tax on sugar-sweetened nonalcoholic beverages has been in effect in Chile, an amount that may be insufficient to produce an impact on obesity levels. The evidence of the effectiveness of fiscal measures upon sugary beverages, in terms of price modification, generally reflects a high transfer of the tax to the final consumers, which is variable according to local conditions. After the analysis of the literature, a sensitivity of the demand to the changes in prices of sugary drinks was evidenced, by means of negative elasticity close to -1, for different groups observed, besides a decrease in the consumption of these products. On the other hand, effects on body weight after the application of these taxes were analyzed by several simulation studies, reporting a decrease on prevalence of obesity between 0.99% and 2.4%. Within the acceptability of a fiscal measure of this nature, there were variable support figures between 36% and 60% among general population. Regarding possible negative effects on employment, an international study even evidenced a rise in the figures for employment in two locations following the application of a tax on sugary drinks. The research showed that there is evidence to support the implementation of a fiscal measure upon sugary beverages in Chile; however, there is a lack of local simulation studies to explore the possible effects and implications of a new tax of this kind in the country. Taxation measures upon foods seem to be both viable and effective alternatives to address the problem of obesity in Chile, but they should be considered as part of an overall strategy with the clear goal of reducing the prevalence of national obesity.

    2010-07-01

    Full Text Available Abstract Background To reduce the production cost of bioethanol obtained from fermentation of the sugars provided by degradation of lignocellulosic biomass (i.e., second generation bioethanol, it is necessary to screen for new enzymes endowed with more efficient biomass degrading properties. This demands the set-up of high-throughput screening methods. Several methods have been devised all using microplates in the industrial SBS format. Although this size reduction and standardization has greatly improved the screening process, the published methods comprise one or more manual steps that seriously decrease throughput. Therefore, we worked to devise a screening method devoid of any manual steps. Results We describe a fully automated assay for measuring the amount of reducing sugars released by biomass-degrading enzymes from wheat-straw and spruce. The method comprises two independent and automated steps. The first step is the making of "substrate plates". It consists of filling 96-well microplates with slurry suspensions of micronized substrate which are then stored frozen until use. The second step is an enzymatic activity assay. After thawing, the substrate plates are supplemented by the robot with cell-wall degrading enzymes where necessary, and the whole process from addition of enzymes to quantification of released sugars is autonomously performed by the robot. We describe how critical parameters (amount of substrate, amount of enzyme, incubation duration and temperature were selected to fit with our specific use. The ability of this automated small-scale assay to discriminate among different enzymatic activities was validated using a set of commercial enzymes. Conclusions Using an automatic microplate sealer solved three main problems generally encountered during the set-up of methods for measuring the sugar-releasing activity of plant cell wall-degrading enzymes: throughput, automation, and evaporation losses. In its present set-up, the

    Excess intake of sugar sweetened beverages (SSBs) has been shown to result in weight gain. To address the growing epidemic of obesity, one option is to combine programmes that target individual behaviour change with a fiscal policy such as excise tax on SSBs. This study evaluates the literature on SSB taxes or price increases, and their potential impact on consumption levels, obesity, overweight and body mass index (BMI). The possibility of switching to alternative drinks is also considered. The following databases were used: Pubmed/Medline, The Cochrane Database of Systematic Reviews, Google Scholar, Econlit, National Bureau of Economics Research (NBER), Research Papers in Economics (RePEc). Articles published between January 2000 and January 2013, which reported changes in diet or BMI, overweight and/or obesity due to a tax on, or price change of, SSBs were included. Nine articles met the criteria for the meta-analysis. Six were from the USA and one each from Mexico, Brazil and France. All showed negative own-price elasticity, which means that higher prices are associated with a lower demand for SSBs. Pooled own price-elasticity was -1.299 (95% CI: -1.089 - -1.509). Four articles reported cross-price elasticities, three from the USA and one from Mexico; higher prices for SSBs were associated with an increased demand for alternative beverages such as fruit juice (0.388, 95% CI: 0.009 - 0.767) and milk (0.129, 95% CI: -0.085 - 0.342), and a reduced demand for diet drinks (-0.423, 95% CI: -0.628 - -1.219). Six articles from the USA showed that a higher price could also lead to a decrease in BMI, and decrease the prevalence of overweight and obesity. Taxing SSBs may reduce obesity. Future research should estimate price elasticities in low- and middle-income countries and identify potential health gains and the wider impact on jobs, monetary savings to the health sector, implementation costs and government revenue. Context-specific cost-effectiveness studies would

    Density and viscosity are properties that exert great influence on the body of wines. The present work aimed to evaluate the influence of the alcoholic content, dry extract, and reducing sugar content on density and viscosity of commercial dry red wines at different temperatures. The rheological assays were carried out on a controlled stress rheometer, using concentric cylinder geometry at seven temperatures (2, 8, 14, 16, 18, 20 and 26 °C). Wine viscosity decreased with increasing temperature and density was directly related to the wine alcohol content, whereas viscosity was closely linked to the dry extract. Reducing sugars did not influence viscosity or density. Wines produced from Italian grapes were presented as full-bodied with higher values for density and viscosity, which was linked to the higher alcohol content and dry extract, respectively. The results highlighted the major effects of certain physicochemical properties on the physical properties of wines, which in turn is important for guiding sensory assessments. © 2014 Society of Chemical Industry.

    Full Text Available The aim of this research was to investigate the effect of hydrocolloid carrageenan, native tapioca starch and powdered whey on viscosity and thermophysical properties of model ice-cream mixtures with reduced content of sugar and fat. Measurements were performed immediately after mixture preparation and after two months of storage at -18 °C. Results showed that rheological properties of model ice-cream mixtures with reduced content of sugar and fat can be improved by addition of starch and whey, particularly at low temperatures (0 and -5 °C. Improvement of properties at low temperatures is particularly important for before mentioned group of products, as well as the fact that raw materials used in the recipes are cost effective and have high nutritive value. Two-month storage at -18 °C resulted in increase of rheological parameters of all investigated samples. Freeze and thaw temperatures of model mixtures were not changed significantly after two months of storage. On the other hand, enthalpies of freezing and thawing have after storage in the most cases decreased.

    In this study, sugar alcohols, dietary fibers, syrups and natural sweeteners were used as sucrose alternatives in the production of reduced sugar chocolates (50% of cocoa parts) with enhanced bioactive profile. Formulated chocolates were evaluated for their physical (particle size distribution, texture) and sensory properties, sugar composition, polyphenolic compounds content and antioxidant capacity. All produced reduced sugar chocolates ensured >20% lower calorific value than conventional chocolate (prepared with sucrose). Formulated chocolates containing stevia leaves and peppermint exhibited the best sensory properties (especially with regard to mouthfeel, sweetness and herbal aroma), as well as the highest polyphenolic content and antioxidant capacity. Particle size and hardness of chocolates increased in comparison to conventional chocolate, in particular when the combination of fructose and isomalt or lactitol was used. The bioactive profile of produced chocolates was enriched with phenolic acids, flavone (luteolin and apigenin) and flavonol (quercetin) derivatives, which were not identified in control chocolate.

    Enough life-support systems are necessary to stay in space for a long term. The management of the meal for astronauts is in particular very important. When an astronaut gets sick in outer space, it means death. To astronauts, the delicious good balance space foods are essential for their work. Therefore, this study was aimed at evaluating space foods menu for the healthy space-life by measuring blood sugar level. We made space foods menu to referred to Japanese nutrition standard in 2010. We made space foods menu which are using "brown rice, wheat, soy bean, sweet potato and green-vegetable" and " loach and insects which are silkworm pupa, snail, mud snail, turmait, fly, grasshopper, bee". We use ten health adults as subjects. Ten subjects performed the sensory test of the questionnaire method. There was the sensuality examination in the item of "taste, a fragrance, color, the quantity" and acquired a mark at ten points of perfect scores. The blood sugar level was measured with peripheral blood, before and after a meal for each 15 minutesduring 120 minutes. Statistical analysis was analysed by Excel statistics. As a result of having measured blood sugar level, the space foods menu understood that hyperglycosemia value after a meal was hard to happen. As a result of sensuality exam-ination of the subject, ten points of evaluation of the taste exceeded eight points in a perfect score. The healthy space foods which were hard to go up of the blood sugar level were made deliciously. We can evaluate space foods leading to good health maintenance of the balance by measuring blood sugar level. An astronaut must be healthy to stay in the space for a long term. Therefore the development of the delicious space foods which increase of the health is essential.

    2014-05-01

    Obesity and overweight prevalence soared to unprecedented levels in the United States, with 1 in 3 adults and 1 in 6 children currently categorized as obese. Although many approaches have been taken to encourage individual behavior change, policies increasingly attempt to modify environments to have a more positive influence on individuals' food and drink choices. Several policy proposals target sugar-sweetened beverages (SSBs), consumption of which has become the largest contributor to Americans' caloric intake. Yet proposals have been criticized for unduly inhibiting choice, being overly paternalistic, and stigmatizing low-income populations. We explored the ethical acceptability of 3 approaches to reduce SSB consumption: restricting sale of SSBs in public schools, levying significant taxes on SSBs, and prohibiting the use of Supplemental Nutrition and Assistance Program (formerly food stamps) benefits for SSB purchases.

    "Nudging"-modifying environments to change people's behavior, often without their conscious awareness-can improve health, but public acceptability of nudging is largely unknown. We compared acceptability, in the United Kingdom (UK) and the United States of America (USA), of government interventions to reduce consumption of sugar-sweetened beverages. Three nudge interventions were assessed: i. reducing portion Size, ii. changing the Shape of the drink containers, iii. changing their shelf Location; alongside two traditional interventions: iv. Taxation and v. Education. We also tested the hypothesis that describing interventions as working through non-conscious processes decreases their acceptability. Predictors of acceptability, including perceived intervention effectiveness, were also assessed. Participants (n = 1093 UK and n = 1082 USA) received a description of each of the five interventions which varied, by randomisation, in how the interventions were said to affect behaviour: (a) via conscious processes; (b) via non-conscious processes; or (c) no process stated. Acceptability was derived from responses to three items. Levels of acceptability for four of the five interventions did not differ significantly between the UK and US samples; reducing portion size was less accepted by the US sample. Within each country, Education was rated as most acceptable and Taxation the least, with the three nudge-type interventions rated between these. There was no evidence to support the study hypothesis: i.e. stating that interventions worked via non-conscious processes did not decrease their acceptability in either the UK or US samples. Perceived effectiveness was the strongest predictor of acceptability for all interventions across the two samples. In conclusion, nudge interventions to reduce consumption of sugar-sweetened beverages seem similarly acceptable in the UK and USA, being more acceptable than taxation, but less acceptable than education. Contrary to prediction, we

    Production of sugar cane in Brazil is 222 million tonnes (harvested wet weight)/year and is processed to sugar (7.5 million tonnes) and ethanol (11.8 million m 3 ) in 1990. The use of fossil fuels in sugar cane production is 271 MJ/t of cane. Sugar cane bagasse and ethanol substitute for fuel oil in the food and chemical industry (including sugar production) and for gasoline (9.75 million m 3 /year), thus avoiding CO 2 emissions from fossil fuels. Considering the fast carbon cycling in sugar cane production and use, net emissions of 9.45 million tonnes of C/year are avoided; this corresponds roughly to 18% of the total CO 2 emissions from fossil fuels in Brazil.

    Full Text Available Kiwifruit (KF effects on the human glycaemic response to co-ingested wheat cereal were determined. Participants (n = 20 consumed four meals in random order, all being made to 40 g of the same available carbohydrate, by adding kiwifruit sugars (KF sug; glucose, fructose, sucrose 2:2:1 to meals not containing KF. The meals were flaked wheat biscuit (WB+KFsug, WB+KF, WB+guar gum+KFsug, WB+guar gum+KF, that was ingested after fasting overnight. Blood glucose was monitored 3 h and hunger measured at 180 min post-meal using a visual analogue scale. KF and guar reduced postprandial blood glucose response amplitude, and prevented subsequent hypoglycaemia that occurred with WB+KFsug. The area between the blood glucose response curve and baseline from 0 to 180 min was not significantly different between meals, 0–120 min areas were significantly reduced by KF and/or guar. Area from 120 to 180 min was positive for KF, guar, and KF+guar, while the area for the WB meal was negative. Hunger at 180 min was significantly reduced by KF and/or guar when compared with WB. We conclude that KF components other than available carbohydrate may improve the glycaemic response profile to co-ingested cereal food.

    Real-time spectroscopic methods can provide a valuable window into food manufacturing to permit optimization of production rate, quality and safety. There is a need for cutting edge sensor technology directed at improving efficiency, throughput and reliability of critical processes. The aim of the research was to evaluate the feasibility of infrared systems combined with chemometric analysis to develop rapid methods for determination of sugars in cereal products. Samples were ground and spectra were collected using a mid-infrared (MIR) spectrometer equipped with a triple-bounce ZnSe MIRacle attenuated total reflectance accessory or Fourier transform near infrared (NIR) system equipped with a diffuse reflection-integrating sphere. Sugar contents were determined using a reference HPLC method. Partial least squares regression (PLSR) was used to create cross-validated calibration models. The predictability of the models was evaluated on an independent set of samples and compared with reference techniques. MIR and NIR spectra showed characteristic absorption bands for sugars, and generated excellent PLSR models (sucrose: SEP 0.96). Multivariate models accurately and precisely predicted sugar level in snacks allowing for rapid analysis. This simple technique allows for reliable prediction of quality parameters, and automation enabling food manufacturers for early corrective actions that will ultimately save time and money while establishing a uniform quality. The U.S. snack food industry generates billions of dollars in revenue each year and vibrational spectroscopic methods combined with pattern recognition analysis could permit optimization of production rate, quality, and safety of many food products. This research showed that infrared spectroscopy is a powerful technique for near real-time (approximately 1 min) assessment of sugar content in various cereal products. © 2012 Institute of Food Technologists®

    To examine the associations between maternal educational level and preschoolers' consumption of high-calorie snacks and sugar-containing beverages, and to assess the mediating effects of variables relating to the family food environment. We analyzed data from 2814 native Dutch preschoolers enrolled in a birth cohort study in Rotterdam (the Netherlands), between 2002 and 2006. Logistic regression models were used to calculate odds ratios of snacking ≥ 2 times/day and consuming sugar-containing beverages ≥ 3 glasses/day for children of mothers with low, mid-low, and mid-high educational levels (reference group: high educational level), before and after adjustment for mediators. Children of low and mid-low educated mothers were significantly more likely to consume excessive amounts of high-calorie snacks and sugar-containing beverages compared with children of high educated mothers, with the highest odds in children of low educated mothers (OR: 2.44; 95% CI: 1.84, 3.23 and OR: 2.46; 95% CI: 1.87, 3.24 respectively). Parental feeding practices, parental consumption of sugar-containing beverages, and children's television time partly explained these associations. Maternal educational level is inversely related to preschoolers' consumption of high-calorie snacks and sugar-containing beverages. Targeting the family food environment may be an effective way of reducing educational inequalities in children's unhealthy dietary behaviors. © 2013.

    Pectin methyl esterase (PME) has been postulated to catalyse the transacylation reaction between pectin molecules. The present study aimed to prove the occurrence of this reaction. The feasibility of applying PME-catalysed transacylation between high-methoxy pectin molecules in making fruit jam with reduced sugar content was also investigated. PME treatment increased the turbidity and particle size in pectin solution and the molecular weight of pectin, while it decreased the number of methoxy ester linkages and the intensity of the CH₃ absorption peak in the Fourier transform infrared spectrum without changes in the number of total ester linkages in pectin molecules. These findings support the occurrence of PME-catalysed transacylation between pectin molecules. Higher values of hardness, gumminess and chewiness were found in a jam containing PME-treated citrus pectin (10 g L⁻¹) and sugar (350 g L⁻¹) as compared with either a jam containing untreated citrus pectin (10 g L⁻¹) and sugar (350 g L⁻¹) or strawberry jam containing pectin (10 g L⁻¹) from the fruit and sugar (650 g L⁻¹). The demand for sugar in jam making can be greatly reduced by the use of PME-treated high-methoxy pectin. Copyright © 2012 Society of Chemical Industry.

    Full Text Available Background: A study to investigate the level of the neurobiochemical marker, Neuron-Specific Enolase (NSE, at the time of admission and its correlation with the blood sugar level in ischemic stroke patients. Patients and Methods: We investigated 90 patients with complete stroke who were admitted to the Stroke Unit of the Department of Neurology at Sri Aurobindo Institute of Medical Sciences. NSE was measured with commercially available quantitative ′sandwich′ enzyme-linked immunosorbent assay kits obtained from R and D Systems. Hyperglycemia was defined as blood glucose concentration ≥ 7 mmol / L, and measured using the glucose oxidase method immediately. Results: Significantly increased NSE and lipid profile levels were found in ischemic stroke patients as compared to the control. Hyperglycemic ischemic stroke patients had increased levels of NSE, lipid profile, and National Institute of Health stroke scale scores (NIHSS score compared to normoglycemic ischemic stroke patients. In addition the serum NSE level of hyperglycemic stroke patients was also positively correlated with the blood sugar level (r = 0.734 P < 0.001. Conclusions: Hyperglycemia predicts an increased risk of poor outcome after ischemic stroke and it is reflected by a significantly increased level of Neuron-Specific Enolase.

    Spent mushroom substrate (SMS) was pretreated with alkaline reagents including potassium hydroxide, lime and ammonia to enhance enzymatic saccharification. Under the best pretreatment conditions (1M KOH, 80 °C, 90 min; 1M lime, 80 °C, 120 min; 10 M ammonia, 70 °C, 120 min), the total reducing sugar (TRS) yield reached 258.6, 204.2 and 251.2 mg/g raw SMS, which were respectively 6.15, 4.86, and 5.98 times of untreated SMS. The effects of pretreatment by above alkaline reagents and sulfuric acid on the composition and structure of SMS were evaluated to provide comparative performance data. A new process, combined alkali and acid (CAA) pretreatment followed by enzymatic hydrolysis, was innovatively proposed to improve the cost-effectiveness and avoid environmental problems. The SMS residue after CAA pretreatment-enzymatic hydrolysis process was converted to biofertilizer with Pichia farinose FL7 and a cell density of 3.0×10(8) cfu/g in biomass was attained.

    Full Text Available Tea (Camellia sinensis is a widely consumed beverage and recognised for its potential enhancing effect on human health due to its rich polyphenol content. While a number of studies have investigated the quantity and type of polyphenols present in different tea samples, no study has reported the potential effect of digestive enzymes on the availability of tea polyphenols for human absorption or the subsequent impact on glycaemic response. The objectives of the present study were to assess the total polyphenol content of different teas, to assess the bioaccessibility of polyphenols in whole and bagged teas, and to determine the effect of black, white, and green tea infusions on sugar release. All of the teas were a significant source of polyphenols (10–116 mg Gallic acid equivalents/g. There was an overall increase in the release of polyphenols from both the bagged and the whole teas following in vitro digestion. Bagged green tea significantly ( reduced rapidly digestible starch from white bread samples compared to control and black and white bagged teas. The present study confirms that tea is a rich source of polyphenols and highlights the potential benefits it may have on modulating glycaemic response in humans.

    Lignocellulosic biomass is a highly rigid and recalcitrant structure which requires pretreatment to loosen chemical bonds to make accessible monomeric sugars for biofuel production. In this study, locally available biomass, that is hemp (Cannabis sativa), a low cost feedstock for ethanol production, has been used for the production of fermentable sugars. Hemp hurd biomass (HHB) was exposed to five different pretreatments which included dilute acid (H{sub 2}SO{sub 4}), alkaline (NaOH), alkaline peroxide, hot water and one stage dilute acid (H{sub 2}SO{sub 4}). Different pretreatments resulted in loosening and degradation of HHB structure thus facilitating enzymatic saccharification at optimized parameters (pH–4.8 and 50 °C). The changes in the reactive groups (hydroxyl or acetyl) of the HHB were confirmed by attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy. Scanning electron microscopy (SEM) was employed to characterize the surface morphology of untreated and treated HHB. Finally, enzymatic saccharification demonstrated maximum yield of total sugars (743 mg g{sup −1}) that are suitable for biofuel production. -- Highlights: • Hemp hurd biomass (HHB) was used for producing fermentable sugars. • Alkaline pretreatment resulted in loosening and degradation of hemp structure. • Pretreated HHB was characterized using FTIR studies. • SEM studies evaluated the opening of fiber bundles in pretreatment, thereby increasing cellulose access to enzymes. • Enzymatic saccharification of pretreated HHB demonstrated maximum yield of reducing sugars.

    Full Text Available Dietary energy for chickens normally includes cereal grains and fat. This innovative study investigated the effect of replacing part of the corn and fat in broiler chicken rations with graded levels of sugar syrup on growth performance and biochemical parameters. Experimental treatments consisted of feeding a corn-soy basal diet alone, or with graded levels of sugar syrup in increments of 5%, 10% and 15%. All starter diets were isonitrogenous and isocaloric. Body weight gain and efficiency of feed utilization of chicks fed the control diet alone were not significantly (P < 0.05 different from chicks fed diets supplemented with either 5% or 15% sugar syrup. Supplementation of sugar syrup to broiler diets had no significant effect on blood glucose, creatinine, total protein, or liver enzymes. Adding 5% sugar syrup to broiler rations significantly decreased blood cholesterol and triglycerides in chickens fed the sugar syrup diet compared with birds fed the control diet. In conclusion, the results shows sugar syrup can be used in poultry ration to replace part of the corn as a source of energy. These results allowed the authors to recommend the safe usage of sugar syrup in broiler rations.

    Full Text Available The lack of suitable plum rootstocks for Baltic conditions has become a problem during recent years due to changing climatic conditions. Rapid temperature fluctuations between freezing and thawing are occurring more frequently. The winter-hardiness of rootstocks is essential for overwintering of trees in such conditions. The content of accumulated reducing sugars is an important physiological factor influencing wintering ability of trees. The dynamics of reducing sugars was investigated during two winter seasons (2010/2011 and 2011/2012 in one-year-old ‘Kubanskaya Kometa’ (Prunus x rossica Erem. hybrid plum shoots from two orchards planted in 2001 at Pūre Horticultural Research Centre (Latvia and Polli Horticultural Research Centre (Estonia. Cultivar ‘Kubanskaya Kometa’ was grafted on eight clonal rootstocks: ‘St. Julien A’, ‘Brompton’ cuttings, ‘Ackermann’, ‘Pixy’, GF8/1, G5/22, GF655/2, ‘Hamyra’ and eight seedling rootstocks: ‘St. Julien INRA 2’, ‘St. Julien d’Orleans’, ‘St. Julien Noir’, ‘Brompton’ seedlings, ‘Wangenheims Zwetsche’, ‘St. Julien Wädenswill’, ‘Myrobаlan’ and Prunus cerasifera var. divaricata. Trees were planted at 5×3 m spacing in four replications per rootstock with three trees per plot. Shoot samples were harvested five times during the winter period. The concentration of reducing sugars (mg g-1 dry weight was determined with Bertran’s method. Significant differences in concentration of reducing sugar were found between samples coming from different locations and in two seasons. The maximum concentration of reducing sugar was found in December or January depending on growing location and meteorological conditions

    Full Text Available Background Flavonoids have been reported as mammalian alpha-amylase inhibitors, a property which could be useful in the management of postprandial hyperglycemia in diabetes and its related disorders. Objectives In the present study the inhibitory effect of aspalathin as a flavonoid on alpha amylase activity and levels of sugar and lipids in rats, has been investigated. Methods In this experimental study, type inhibition of aspalatin on amylase and in the part of in vivo, the effect of aspalathin orally doses 5, 10, 20 and 40 mg/kg body weight on sugar and lipids levels was tested in a streptozotocin-induced model of diabetes and normal rats. The data were analyzed by one-sample Kolmogrov-Smirnov, Levene and ANOVA tests through SPSS version 22. Results The results showed that aspalathin is a competitive inhibitor for alpha amylase with Ki = 37.0 μM. In both diabetic and normal groups in all doses nearly dose dependent manner reduced blood glucose levels and beneficial effect on dyslipidemia were observed in diabetic rats, as well as reduction of disturbing consequences of diabetes such as high urine volume and water intake. Aspalathin was observed to have a weight loss-inductive effect, alongside with a reduction in food intake. Conclusions It seems that, this compound could be proposed as an antihyperglycemic and antihyperlipidemic agent in diabetes and potential therapeutic in obesity.

    Sugar-sweetened beverages are a major source of free sugar intake in both children and adults, and are an important contributor to obesity and obesity-related diseases, including type 2 diabetes. We proposed an incremental and stepwise reduction in free sugars added to sugar-sweetened beverages by 40% over 5 years without the use of artificial sweeteners and assessed the effect of the proposed strategy on energy intake and weight status. In this modelling study, we used nationally representative data from the National Diet and Nutrition Survey rolling programme (NDNS RP) from 2008-12 and British Soft Drinks Association annual reports to calculate sugar-sweetened beverage consumption (both with and without fruit juices) and its contribution to free sugar and energy intake in the UK population. We then estimated the predicted reduction in energy intake resulting from the proposed strategy at an individual level. We further predicted the reduction in steady-state bodyweight for each adult using a weight loss model. By scaling up the distribution of the predicted bodyweight in the NDNS RP to the UK adult population, we estimated reductions in the number of overweight and obese adults, and the number of adults with type 2 diabetes. A 40% reduction in free sugars added to sugar-sweetened beverages over 5 years would lead to an average reduction in energy intake of 38·4 kcal per day (95% CI 36·3-40·7) by the end of the fifth year. This would lead to an average reduction in steady-state bodyweight of 1·20 kg (1·12-1·28) in adults, resulting in a reduction in the prevalence in adults of overweight by 1·0 percentage point (from 35·5% to 34·5%) and obesity by 2·1 percentage points (from 27·8% to 25·7%). This reduction would lead to a reduction of roughly 0·5 million adults from being overweight and 1 million adults from being obese, which in turn would prevent about 274,000-309,000 incident cases of obesity-related type 2 diabetes over the two decades after the

    Sugar-free (SF), sugar-reduced (SR), or low-glycemic-index (low GI) cereal products could be helpful for the dietary treatment of disorders related to glucose homeostasis. However, access and economic aspects are barriers that could hamper their consumption. Thus, the availability and price of such cereal products were evaluated in Northwestern México. The products were categorized in 10 groups. The data were collected in five cities by store visitation (from November 2015 to April 2016). The availability in specialized stores and supermarkets was expressed as availability rates based on the total number of products. The price of the SF, SR, and low GI products were compared with their conventional counterparts. Availability rates were higher in supermarkets than in specialized stores by product numbers (14.29% versus 3.76%, respectively; p snacks, and tostadas/totopos) had higher prices than their conventional counterparts ( p < 0.05). In conclusion, in Northwestern Mexico, the availability of SF, SR, and low GI cereal-based foods is relatively low, and these foods are more expensive than their conventional counterparts.

    The reduction of free or added sugar intake (sugars added to food and drinks as a sweetener) is almost universally recommended to reduce the risk of obesity-related diseases and dental caries. The World Health Organisation recommends intakes of free sugars of less than 10% of energy intake. However, estimating and monitoring intakes at the population level is challenging because free sugars cannot be analytically distinguished from naturally occurring sugars and most national food composition...

    analyzed using statistical package SAS and means were compared using LSD test at the level of statistical significance of P˂0.05. Results and Discussion: The results indicated that GA3 affected all the measured characteristics except carotenoids in comparison with thiamine and ascorbic acid. Meanwhile, the combined application of GA3 and ascorbic acid affected stem growth, root growth and flower diameter. Simultaneous use of GA3 and thiamine was effective on pigments, reducing sugar, carotenoids and flower number. The simultaneous application of three chemicals resulted in a considerable increase in growth and development traits, such as stem and root growth, flower number and diameter, pigments and reducing sugar compared to control. Generally, gibberellic acid will increase vegetative growth with impress cellular processes, including stimulation cell division and cell elongation. It was reported that the uses of ascorbic acid and gibberellic acid in Thyme (Thymus vulgaris increased plant height and root length. Ascorbic acid makes a set of functions such as cell division and enlargements, cell wall development and other developmental processes in plants. Ascorbic acid affects plasma membrane proton pump and according to the acidic theory stimulates weaking cell wall and consequently will increase cell wall development and cell enlargement. It was found that thiamine significantly increased flower number in chrysanthemum . Conclusion: The results indicated that the synergistic effects of this material can be used to enhance the growth and development of petunia. On the other hand, in arid and semiarid areas of the country, that drought and salinity stresses somewhat inevitable, these materials, especially vitamins are effective in reducing stress and increase flowering period.

    The prevalence of diabetes is rapidly rising all over the globe at an alarming rate. In India, more than 61.3 million people have been presently diagnosed with type 2 diabetes mellitus. It is possible to control the circulating blood glucose levels by reducing life style risk factors through physical activities comprising of muscle stretches, aerobic training, resistance exercises (REs), yoga, etc. The aim of this study is to identify and compare the immediate effect of passive static stretching (PSS) versus RE on blood glucose level in individuals with type 2 diabetes mellitus. The present study included 51 participants between the age of 40-65 years with type 2 diabetes mellitus, to study the immediate effect of 60-min PSS (n=25) and 60-min RE (n=26). The outcome measure was blood glucose level which was checked by glucometer (free-style neo). Blood sugar was assessed at 3 points of time that included fasting blood sugar level, 2 hr after the meal and immediately after the exercise regimen. Results of this study showed significant reduction in blood glucose level in subjects according to glucometer with PSS ( P =0.000) and RE ( P =0.00). However, both groups demonstrated equal effect in terms of lowering blood sugar level immediately after the exercise. The conclusion is both PSS and RE are effective in reducing postprandial blood glucose level in type 2 diabetes mellitus and must be prescribed for the patients who demonstrate difficulty in controlling post prandial spike.

    Tooth decay is the most common paediatric disease and there is a serious paediatric tooth decay epidemic in Alaska Native communities. When untreated, tooth decay can lead to pain, infection, systemic health problems, hospitalisations and in rare cases death, as well as school absenteeism, poor grades and low quality-of-life. The extent to which population-based oral health interventions have been conducted in Alaska Native paediatric populations is unknown. To conduct a systematic review of oral health interventions aimed at Alaska Native children below age 18 and to present a case study and conceptual model on multilevel intervention strategies aimed at reducing sugar-sweetened beverage (SSB) intake among Alaska Native children. Based on the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) Statement, the terms "Alaska Native", "children" and "oral health" were used to search Medline, Embase, Web of Science, GoogleScholar and health foundation websites (1970-2012) for relevant clinical trials and evaluation studies. Eighty-five studies were found in Medline, Embase and Web of Science databases and there were 663 hits in GoogleScholar. A total of 9 publications were included in the qualitative review. These publications describe 3 interventions that focused on: reducing paediatric tooth decay by educating families and communities; providing dental chemotherapeutics to pregnant women; and training mid-level dental care providers. While these approaches have the potential to improve the oral health of Alaska Native children, there are unique challenges regarding intervention acceptability, reach and sustainability. A case study and conceptual model are presented on multilevel strategies to reduce SSB intake among Alaska Native children. Few oral health interventions have been tested within Alaska Native communities. Community-centred multilevel interventions are promising approaches to improve the oral and systemic health of Alaska Native

    While experimental and observational studies suggest that sugar intake is associated with the development of type 2 diabetes, independent of its role in obesity, it is unclear whether alterations in sugar intake can account for differences in diabetes prevalence among overall populations. Using econometric models of repeated cross-sectional data on diabetes and nutritional components of food from 175 countries, we found that every 150 kcal/person/day increase in sugar availability (about one can of soda/day) was associated with increased diabetes prevalence by 1.1% (p <0.001) after testing for potential selection biases and controlling for other food types (including fibers, meats, fruits, oils, cereals), total calories, overweight and obesity, period-effects, and several socioeconomic variables such as aging, urbanization and income. No other food types yielded significant individual associations with diabetes prevalence after controlling for obesity and other confounders. The impact of sugar on diabetes was independent of sedentary behavior and alcohol use, and the effect was modified but not confounded by obesity or overweight. Duration and degree of sugar exposure correlated significantly with diabetes prevalence in a dose-dependent manner, while declines in sugar exposure correlated with significant subsequent declines in diabetes rates independently of other socioeconomic, dietary and obesity prevalence changes. Differences in sugar availability statistically explain variations in diabetes prevalence rates at a population level that are not explained by physical activity, overweight or obesity.

    The impact of fructose, commonly consumed with sugars by humans, on blood pressure and uric acid has yet to be defined. A total of 267 weight-stable participants drank sugar-sweetened milk every day for 10 weeks as part of their usual, mixed-nutrient diet. Groups 1 and 2 had 9% estimated caloric intake from fructose or glucose, respectively, added to milk. Groups 3 and 4 had 18% of estimated caloric intake from high fructose corn syrup or sucrose, respectively, added to the milk. Blood pressure and uric acid were determined prior to and after the 10-week intervention. There was no effect of sugar type on either blood pressure or uric acid (interaction P>.05), and a significant time effect for blood pressure was noted (Pfructose at the 50th percentile level, whether consumed as pure fructose or with fructose-glucose-containing sugars, does not promote hyperuricemia or increase blood pressure. © 2014 Wiley Periodicals, Inc.

    Several uremic toxins have been identified and related to higher rates of morbidity and mortality in dialysis patients. Bisphenol A (BPA) accumulates in patients with chronic kidney disease. The aim of this study is to demonstrate the usefulness of online hemodiafiltration (OL-HDF) in reducing BPA levels. Thirty stable hemodialysis patients were selected to participate in this paired study. During three periods of 3 weeks each, patients were switched from high-flux hemodialysis (HF-HD) to OL-HDF, and back to HF-HD. BPA levels were measured in the last session of each period (pre- and post-dialysis) using ELISA and HPLC. Twenty-two patients (mean age 73 ± 14 years; 86.4% males) were included. Measurements of BPA levels by HPLC and ELISA assays showed a weak but significant correlation (r = 0.218, P = 0.012). BPA levels decreased in the OL-HDF period of hemodialysis, in contrast to the HF-HD period when they remained stable (P = 0.002). In conclusion, OL-HDF reduced BPA levels in dialysis patients. © 2016 International Society for Apheresis, Japanese Society for Apheresis, and Japanese Society for Dialysis Therapy.

    Excess sugar consumption may promote adverse changes in hepatic and total body insulin resistance. Debate continues over the effects of sugars at more typically consumed levels and whether the identity of the sugar consumed is important. In the present study participants (20-60 years old) were randomly assigned to one of five groups, three that consumed low fat milk with added fructose containing sugars in amounts equivalent to the 50th percentile of fructose consumption (US), one which consumed low-fat milk sweetened with glucose, and one unsweetened low-fat milk control group. The intervention lasted ten weeks. In the entire study population there was less than 1 kg increase in weight (73.6 ±13.0 vs. 74.5 ± 13.3 kg, p 0.05). There were no changes in fasting glucose (49 ± 0.4 vs. 5.0 ± 0.5 mmol/L), insulin (56.9 ± 38.9 vs. 61.8 ± 50.0 pmol/L), or insulin resistance, as measured by the Homeostasis Model Assessment method (1.8 ± 1.3 vs. 2.0 ± 1.5, all p > 0.05). These data suggest that added sugar consumed at the median American intake level does not produce changes in measures of insulin sensitivity or glucose tolerance and that no sugar has more deleterious effects than others.

    To determine the barriers and enablers to behavioural change to reduce free sugar intake related to dental caries in a sample of UK adults who identify their ethnicity as White. Qualitative study comprising semi-structured interviews of 27 participants. Interviews were recorded, transcribed and analysed using thematic analysis methods. The Capability-Opportunity-Motivation-Behaviour model (COM-B) and the Theoretical Domains Framework (TDF) were used to guide the derivation of themes. Data saturation occurred at 27 interviews. The COM-B Model and TDF domains captured various factors that may influence the consumption of free sugar. TDF elements which are reflected in the study are: Knowledge; Psychological skills; Memory, attention, and decision processes; Behavioural regulation; Physical skills; Social influence; Environmental context and resources; Social and professional role and identity; Beliefs about capabilities; Beliefs about consequence; Intentions and goals reinforcement; and Emotions. COM-B Model elements which are reflected in the study are: psychological capabilities, physical capabilities, social opportunities, physical opportunities, reflective motivation, and automatic motivation. The COM-B model and TDF framework provided a comprehensive account of the barriers and facilitators of reducing sugar intake among white ethnic groups.

    The aim of the study was to determine the influence of pressure in high-pressure-high-temperature (HPHT) processing on Maillard reactions and protein aggregation of whey protein-sugar solutions. Solutions of whey protein isolate containing either glucose or trehalose at pH 6, 7, and 9 were treated by HPHT processing or conventional high-temperature (HT) treatments. Browning was reduced, and early and advanced Maillard reactions were retarded under HPHT processing at all pH values compared to HT treatment. HPHT induced a larger pH drop than HT treatments, especially at pH 9, which was not associated with Maillard reactions. After HPHT processing at pH 7, protein aggregation and viscosity of whey protein isolate-glucose/trehalose solutions remained unchanged. It was concluded that HPHT processing can potentially improve the quality of protein-sugar-containing foods, for which browning and high viscosities are undesired, such as high-protein beverages.

    The CAM plant Aloe vera was vegetatively propagated and grown under three irradiances: full sun, partial and deep shade (30% and 10% of ambient light, respectively) to determine the effect on growth, biomass allocation, and sugar concentration. After one year, the plants were harvested to determine final dry weight and the sugar concentration of the leaf mucilaginous gel. Plants grown under full sun produced twice the total dry weight of those grown under partial shade, with the difference equally partitioned between the shoot and root. Plants grown under full sun also produced thicker leaves, and more numerous and large auxiliary shoots. The dry weight of plants grown under deep shade was 8.6% that of plants grown under full sun, which was directly proportional to the irradiance received. Partial shade increased the number and length of leaves produced on the primary shoot, but the allocation of carbon to roots was the lowest of all treatments. Partial shade reduced the total sugar concentration of the leaf gel matrix to 34% that of plants under full sun, due to reductions in all sugars measured. Glucose was the most abundant soluble sugar, with its relative contribution to the total pool increasing under shade. In summary, the proportional effects of partial shading were greater on soluble sugar concentrations than on the total plant biomass produced.

    The frequent and high consumption of sugar products, particularly sucrose, is one of the causative factors of dental caries. Meta-analyses assessing the relationship between sugar intake and dental caries revealed that a restricted sugar intake to less than 10% of the daily energy intake results in substantial health benefits. Sugar consumption in Poland is 2-fold higher than recommended by the WHO. As change in dietary habits is slow, knowledge of whether a gradual reduction of sugar consumption influences beneficially the dental condition is important. Assessment of the relationship between caries experience and sugar consumption in 12-year-old children. The data obtained from the Statistical Agricultural Yearbooks of the Central Statistical Office in Poland regarding the average yearly sugar intake by a person in the years 1995-2013, and caries prevalence (frequency and DMFT) resulting from the national epidemiological studies of the 12-year-old children conducted by the Ministry of Health in those years were analyzed. The data was analyzed by linear regression. Regression function parameters and coefficients of determination were assessed for a possible link between sugar consumption and dental caries frequency and severity was expressed as DMFT value. The mean yearly sugar intake by a statistical Pole ranged from 43.6 kg (2002) to 35.3 kg (2006). Despite a slight trend to lower the sugar consumption, its mean intake in 1995 and 2013 was the same (41.9 kg). Caries frequency and DMFT decreased in 2012 compared to 1995 from 90.5% to 79.6% and from 4.3 to 3.53 kg in 2012, respectively. The increased sugar intake by 1 kg/year caused the increase of caries frequency by 1% and DMFT value by 0.2. Even a relatively low decrease in sugar consumption can exert some beneficial influence on the dental condition in adolescents, particularly upon the severity of caries.

    Objective: To investigate the changes of serum leptin, insulin levels and blood sugar contents in pregnant women with gestational glucose metabolism disturbances. Methods: Fasting and 3h after oral 50g glucose serum levels of leptin were measured with RIA in 36 pregnant women with glucose metabolism disturbances (gestational diabetes mellitus or gestational impaired glucose tolerance) and 34 controls. Also, fasting serum insulin levels (with CLIA) and blood sugar contents 1h after oral 50 glucose (with glucose oxidase method) were determined in all these subjects. Results: 1. Serum levels of leptin in pregnant women with glucose metabolism disturbances were 14.9 ± 4.3 μg/L (vs controls 9.8 ± 1.7 μg/L, P<0.01). 2. The serum levels of insulin and 1 h post - 50g glucose blood sugar contents in pregnant women with glucose metabolism disturbances were 12.9±4.3mU/L and 11.0±1.4mmol/L respectively, which were both significantly positively correlated with the serum leptin levels (r=0.835, r=0.758 respectively) (vs levels in controls: 8.45±3.0mU/L and 7.84±1.3mmol/L). Conclusion: Elevation of fasting serum levels of leptin was demonstrated in pregnant women with glucose metabolism disturbances and the level of leptin was positively correlated with that of insulin and blood sugar.

    2013-06-01

    While childhood obesity is a global problem, the extent and severity of the problem in United States, has resulted in a number of new initiatives, including recent hospital initiatives to limit the sale of sweetened beverages and other high calorie drinks in hospital vending machines and cafeterias. These proposed policy changes are not unique to United States, but are more comprehensive in the number of proposed hospitals that they will impact. Meanwhile, however, it is advised, that these initiatives should focus on banning sugar sweetened beverages, including sodas, 100% fruit juice and sports drinks, from hospital cafeterias and vending machines instead of limiting their presence, so as to ensure the success of these programs in reducing the prevalence of childhood obesity. If US hospitals comprehensively remove sugar sweetened beverages from their cafeterias and vending machines, these programs could subsequently become a model for efforts to address childhood obesity in other areas of the world. Hospitals should be a model for health care reform in their communities and removing sugar sweetened beverages is a necessary first step. ©2013 Foundation Acta Paediatrica.

    The dosage liquid, added at the final stage of sparkling wine production, imparts residual sweetness to the wine. No study has yet analyzed the influence of dosage composition on the final wine's sensory profile or consumer acceptance. In this study, dosage composition was altered through the addition of different sugar types (ST; fructose, glucose, or sucrose) to produce seven sparkling wines of varying residual sugar levels (RSL), including no sugar added, brut (5.3-8.4gST/L) or demi sec (34.9-37.8gST/L). As evaluated by a trained panel (n=9), the interaction between ST and RSL influenced the perception of caramelized/vanilla/honey (CVH) flavor, sweet taste, and sour taste attributes (pConsumers (n=126) also evaluated the sparkling wines and ST, RSL, and their interaction influenced consumer acceptance of different attributes, as well as the perception of the "refreshing" aspect of the wine (pconsumer acceptance of sparkling wines was highly correlated (r 2 ≤0.88) to CVH, floral, and fruity flavors, as well as sweet taste and creamy mouthfeel. External preference mapping revealed two clusters of consumers. Both consumer clusters liked wines sweetened with fructose, but Cluster 1 liked the demi sec sparkling wine sweetened with fructose (32.8g/L fructose) while Cluster 2 preferred the brut wine sweetened with fructose (8.4g/L fructose). These results suggest that consumer preference for sparkling wine was segmented based on sweetness preference. The results of this study offer winemakers knowledge about the influence of dosage composition on the sensory profile of sparkling wine. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Three lignocelluloses substrates have been used, as following: Mischantus, Maize stalk and Wheat bran, in order to obtain fermentescible sugars, which will be transformed into bioethanol. The substrates were hydrolysed using commercial enzymes: MethaPlus (b-glucanase, xylanase, cellulase, Veron 191 (xylanase, Hep C (cellulase. The hydrolysis was performed at 550 C, for 20 h, at pH = 5,5. The best results were obtained by using MethaPlus enzyme. The efficiency of hydrolysis was 110.80 % for Miscanthus, 126.15 % for maize stalk and 118.76 % for wheat bran, reported to the control. The most enhanced quantities of reducing sugars were obtained in maize stalk, namely: 126.15 % using MethaPlus, 112.07 % using Veron 191 and 113.52 % using Hep C. The wheat bran was hydrolysed with enzymatic mixtures, for emphasizing the reducing sugars’ grow, coming from residual starch’s content (flour. In comparison to the control, the efficiency of hydrolysis was of: 181.004 % for MethaPlus-Veron M4 mixture, 168.83 % for MethaPlus-Veron 393 mixture, 205.86 % for MethaPlus-BG a-malt mixture and of 176.57 % for MethaPlus-Veron MX mixture. The enzymatic mixture which contains BG a-malt was the most productive, the hydrolysis efficiency being superior to all other variants.

    2017-05-01

    The effect of ripening on the formation of acrylamide in deep fried plantain chips made from Nendran variety (Musa paradisiaca) was investigated. The precursors of acrylamide formation, reducing sugars (glucose and fructose) and ten major amino acids, were quantified during different stages of ripening using HPLC and correlated with acrylamide formation. The total phenolic content and total flavonoid content were also estimated and correlated with acrylamide formation. Both glucose and fructose increased during ripening and demonstrated a positive correlation on formation of acrylamide (correlation coefficient of r=0.95 and 0.94 respectively (p0.05). The decreased levels of phenolic content during ripening of plantain were negatively correlated with acrylamide formation in the deep fried chips prepared. Thus the selection of proper ripening stage renders reduced formation of acrylamide in plantain chips to a reasonable extend. Copyright © 2016 Elsevier Ltd. All rights reserved.

There were no changes in fasting glucose (49 ± 0.4 vs. 5.0 ± 0.5 mmol/L, insulin (56.9 ± 38.9 vs. 61.8 ± 50.0 pmol/L, or insulin resistance, as measured by the Homeostasis Model Assessment method (1.8 ± 1.3 vs. 2.0 ± 1.5, all p > 0.05. These data suggest that added sugar consumed at the median American intake level does not produce changes in measures of insulin sensitivity or glucose tolerance and that no sugar has more deleterious effects than others.

    Excess sugar consumption in children has led to the removal of chocolate milk from some schools. Lower-sugar formulations, if accepted, would provide the benefits of milk consumption. In a cross-over trial, milk consumption was measured in 8 schools over 6 weeks in 2 phases: phase 1 provided standard 1% chocolate milk and plain 2% milk choices for the first 3 weeks, and phase 2 provided reduced-sugar 1% chocolate milk and plain 2% milk for the next 3 weeks. Milk selection and milk wasted were measured by sex and grade (1-8). Children chose chocolate milk more often than white milk in both phases (phase 1, 8.93% ± 0.75% vs. 0.87% ± 0.11% (p chocolate milk in phase 2 (p chocolate milk over plain milk even when a reduced-sugar formula was offered; however, switching to reduced-sugar chocolate milk led to a decrease in the number of students choosing milk. Longer-duration studies are required to determine if students would purchase reduced-sugar chocolate milk at the same rate as they would purchase regular chocolate milk.

    Food security has been defined as the "availability, stability, access and utilization of safe foods". Diabetes has been known as one of the biggest health and medical problems throughout the world and is clearly related to lifestyle, and particularly, improper food consumption. The aim of this study was to determine the relationship between food security with sugar and blood pressure in patients suffering from type 2 diabetes who refer to diabetes centers in Tehran. This cross-sectional study was conducted in 2015 on type 2 diabetes patients in Tehran, Iran. From two diabetes centers in the eastern and southern parts of Tehran, 243 type 2 diabetes patients were selected. Necessary information (demographic and food security information) about all the studied persons was collected using the standard questionnaire verified by US Department of Agriculture (USDA). The data was analyzed by SPSS version 16, statistical comparisons were made using analysis of variance (ANOVA) and Chi-square and Tukey tests and a significant level of food security (p=0.372). No significant relation was observed between food security and fasting blood pressure, HbA1C, and systolic blood pressure (p>0.05), but there was a significant relationship between food security and diastolic blood pressure (p= 0.030). According to the relationship between diastolic blood pressure and food security and the role of blood pressure in the irreparable diabetic complications, it is recommended to perform appropriate food advice.

    This study aimed to examine the effect of a multicomponent intervention program on consumption of sugar-sweetened beverages (SSBs), and lifestyle factors associated with SSB intake, in Hispanic children from low-income families. A five-wave longitudinal study using a quasi-experimental design was conducted. Five elementary schools in West Texas served as the setting. Participants included 555 predominantly Hispanic children (ages 5-9 years) from low-income families and their parents (n = 525). A multicomponent intervention program was implemented. Children's anthropometric measures were obtained. Their weight status was determined based on body mass index for age and gender. Parents responded to a demographic questionnaire, a shelf inventory, an acculturation scale, and a family survey. Growth curve analyses were used to test differences between intervention and comparison participants' SSB intake and to examine potential covariates. Comparison group children's daily SSB intake significantly increased over time (B = 1.06 ± .40 ounces per month, p food intake, and more types of SSBs available at home were associated with higher SSB intake. Risk factors of childhood obesity were associated with each other. The intervention program produced a modest reduction in SSB consumed by economically disadvantaged and predominantly Hispanic children. © 2016 by American Journal of Health Promotion, Inc.

    Vecino-Ortiz, Andres I; Arroyo-Ariza, Daniel

    2018-05-26

    Colombia has a high prevalence of overweight (56%) and obesity (19%) among adults and is experiencing a growing trend in the prevalence of associated chronic conditions. Evidence suggests that sugar sweetened beverages (SSB) are associated to overweight/obesity, and that taxes on these beverages could reduce their associated health consequences. This paper assesses the potential effect of different levels of a SSB tax in Colombia on overweight and obesity prevalence. Using peer-reviewed local data on own-price elasticity of SSB, we applied a comparative risk assessment strategy to simulate the effect of the SSB tax on a nationally representative nutritional survey with 7140 adults in 2010 (ENSIN, 2010). Our results varied depending on the tax scenario, pass-through assumption and household socio economic strata (SES). We found that among individuals belonging to lower SES households, the SSB tax would reduce overweight and obesity between 1.5-4.9 and 1.1-2.4 percentage points (p tax rate of at least 75 cents of Colombian peso (0.75 COP) per milliliter (24% of the average price) is needed to have statistically significant effects on both overweight and obesity prevalence among lower SES households. The results of this study suggest that a SSB tax could reduce the overweight and obesity prevalence in Colombia, especially among lower SES households. This study shows that SSB taxes have a particularly beneficial effect in the most vulnerable population. Additional social and individual benefits, or individual costs arising from the tax are not assessed in this research, implying that even larger health gains could be observed.

  20. Pectinase activity determination: an early deceleration in the release of reducing sugars throws a spanner in the works!

    Directory of Open Access Journals (Sweden)

    Alessandra Biz

    Full Text Available Recently, it has been suggested that pectinases could be used to hydrolyze pectin in biorefineries based on pectin-rich agro-industrial wastes. However, for this to be viable, the cost of their production would need to be lowered significantly. In fact, over the last few decades, there have been many attempts to improve pectinase production by existing strains or to screen for new strains from environmental isolates. In these studies, it is necessary to measure pectinase activities. Many researchers use single-time-point assays that involve incubation of pectinolytic extracts with pectic substrates for a fixed time, followed by determination of the liberated reducing sugars. However, different researchers use quite different conditions for this assay. Furthermore, no attention has been given to the reaction profile during the assay. In the current work, we show, for the first time, that a significant deceleration of the rate of liberation of reducing sugars occurs over the first ten minutes of the reaction. As a consequence, the incubation time used in a single-time-point assay has a large effect on the value obtained for the activity. In fact, we demonstrate that, depending on the particular combination of incubation time, pectin concentration and reaction temperature, the same extract could be reported to have activities that differ by an order of magnitude. In addition, we show that the relative activities obtained with polygalacturonic acid do not correlate with those obtained with pectin. We conclude that it is currently impossible to make meaningful comparisons between pectinase activities reported in the literature by workers who have used different assay conditions. Therefore there is an urgent need for the development of a standardized assay for evaluating the saccharification potential of pectinase complexes.

    Previous research on male white rat with provision of Eurycoma longifolia until the 3rd days has increased significantly on the formation of final spermatid from spermatozoon, and testosterone, and increase activity of pituitary cell producing the LH hormone. However, these researches yet studied on possibility of side effects caused by provision of Eurycoma longifolia for 6 days on male EC goat. The research aims to measure the effect of Eurycoma longifolia on the levels of: 1). Blood sugar, 2). Cholesterols, and 3). Uric acid of Male Etawa Crossbreed (EC) goat. This research was conducted through two treatment groups, namely : 1). Control group (provision of aquadest) for 1 day, 3 days, and 6 days, 2) Eurycoma longifolia group with a dose of 90 mg/kg body weight (bb) for 1 day, 3 days, and 6 days. Measurements on the sugar blood, cholesterol and uric acid level were conducted in the 1st, 2nd and 6th days. The obtained data were analyzed using Duncan test with confidence level by 95% (α=0,05) comparing the sugar blood, cholesterol and uric acid measured from the control group in the 1st, 3rd and 6th days with the same compound level measured from the Eurycoma longifolia treatment group in the 1st, 3rd and 6th days. The result obtained there were no significant changes on the sugar blood, cholesterol and uric acid levels between all Eurycoma longifolia treatment groups compared to the control group in the 1st, 3rd and 6th days. Thus, the Eurycoma longifolia provision until in the 6th day did not provide any negative side effects and can be applied in the Etawa crossbreed goat farm.

    To report dietary sugars consumption and their different types and food sources, in European adolescents. Food consumption data of selected groups were obtained from 1630 adolescents (45.6% males, 12.5-17.5 years) from the HELENA study using two nonconsecutive 24-h recalls. Energy intake, total sugars and free sugars were assessed using the HELENA-DIAT software. Multiple regression analyses were performed adjusting for relevant confounders. Total sugars intake (137.5 g/day) represented 23.6% and free sugars (110.1 g/day), 19% of energy intake. Girls had significantly lower intakes of energy, carbohydrates, total sugars and free sugars. 94% of adolescents had a consumption of free sugars above 10% of total energy intake. The main food contributor to free sugars was 'carbonated, soft and isotonic drinks,' followed by 'non-chocolate confectionary' and 'sugar, honey, jam and syrup.' Older boys and girls had significantly higher intakes of free sugars from 'cakes, pies and biscuits.' Free sugars intake was negatively associated with low socioeconomic status for 'non-chocolate confectionary' and 'sugar, honey and jam' groups; with low maternal educational level for carbonated and 'soft drinks,' 'sugar, honey and jam,' 'cakes and pies' and 'breakfast cereals' groups; and with high paternal educational level for 'carbonated and soft drinks' and 'chocolates' group. The majority (94%) of studied adolescents consumed free sugars above 10% of daily energy intake. Our data indicate a broad variety in foods providing free sugars. Continued efforts are required at different levels to reduce the intake of free sugars, especially in families with a low educational level.

    Specimen damage by electron radiation is one of the factors that limits high resolution electron microscopy of biological specimens. A method was developed to record images of periodic objects at a reduced electron exposure in order to preserve high resolution structural detail. The resulting image would tend to be a statistically noisy one, as the electron exposure is reduced to lower and lower values. Reconstruction of a statistically defined image from such data is possible by spatial averaging of the electron signals from a large number of identical unit cells. (U.S.)

    Nectar composition within a plant pollinator group can be variable, and bird pollinated plants can be segregated into two groups based on their adaptations to either a specialist or an occasional bird pollination system. Specialist nectarivores rely primarily on nectar for their energy requirements, while occasional nectarivores meet their energy requirements from nectar as well as from seeds, fruit and insects. Avian blood plasma glucose concentration (PGlu) is generally high compared with mammals. It is also affected by a range of factors including species, gender, age, ambient temperature, feeding pattern, reproductive status, circadian rhythm and moult status, among others. We examined whether sugar content affected PGlu of two avian nectarivores, a specialist nectarivore the Amethyst Sunbird Chalcomitra amethystina, and an occasional nectarivore the Cape White-eye Zosterops virens, when fed sucrose-hexose sugar solution diets of varying concentrations (5%-35%). Both species regulated PGlu within a range which was affected by sampling time (fed or fasted) and not dietary sugar concentration. The range in mean PGlu was broader in Amethyst Sunbirds (11.52-16.51mmol/L) compared with Cape White-eyes (14.33-15.85mmol/L). This suggests that these birds are not constrained by dietary sugar concentration with regard to PGlu regulation, and consequently selective pressure on plants for their nectar characteristics is due to reasons other than glucose regulation. © 2013.

    Sugar maple (Acer saccharum Marsh.) seedlings often have poor survival on acidic unglaciated portions of the Allegheny Plateau. Greater survival is found after lime treatment of unglaciated sites or on glaciated areas of the Plateau. The difference in survival rate may depend in part on the acidity or chemical composition of the soil.

    The effect of reducing sugars on formation of PhIP in fried pork was investigated, and the underlying mechanisms were revealed by studying the reaction pathways between α-dicarbonyl compounds (α-DCs) and PhIP. The addition of reducing sugars (such as glucose) greatly reduced the amount of PhIP in fried pork from 15.5 ng/g to less than 1.0 ng/g. The amount of PhIP decreased significantly with an increasing level of added α-DCs in model systems. Similarly, the addition of methylglyoxal (MGO) decreased significantly the levels of phenylalanine (Phe) and creatinine (Crn) but increased significantly the level of phenylacetaldehyde (PEA). 2-Amino-1-methyl-5-(2-oxopropylidene)-imidazol-4-one and N-(1-methyl-4-oxoimidazolidin-2-ylidene) amino propionic acids were identified in MGO/Crn and MGO/Crn/Phe model systems and fried pork with glucose. These results revealed that the degradation products of reducing sugars-α-DCs-play an important role in inhibiting formation of PhIP by reacting with key precursors of PhIP and itself.

    Full Text Available Palm sugar-like flavouring (PSLF is a type of flavour product that is formed by heating amino acids and sugar under specific heating conditions. Unfortunately, PSLF has a salty taste and contains high amounts of acrylamide. Hence, the objective of this research was to reduce saltiness and acrylamide without negatively affecting the aroma properties of PSLF. A decrease in the sodium phosphate (NaHPO4 buffer concentration from 0.20 to 0.02 M was found to reduce sodium to approximately 15% of the level found in original PSLF. A further decrease (~25% in the sodium content was achieved by removing monobasic sodium phosphate (NaH2PO4 from the buffer system. Meanwhile, the addition of CaCl2 at 20–40 mg/L reduced the acrylamide content in PSLF by as much as 58%. A CaCl2 concentration of 20 mg/mL was most favourable as it most efficiently suppressed acrylamide formation while providing an acceptably high flavour yield in PSLF. In view of the high acrylamide content in PSLF, additional work is necessary to further reduce the amount of acrylamide by controlling the asparagine concentration in the precursor mixture.

    Full Text Available Investigated the extent of adsorption removal of calcium carbonate pigments - products of conversion of the reducing substances in different conditions of the preceding limestone processing flow. Also carried out experiments on the influence of the conditions of conversion of the reducing substances in the process of lime treatment on the filtration characteristics of the solutions after the first carbonation. As the criterion was accepted the value of the filtration coefficient. Found that by subjecting the conversion of reducing substances in the process managed lime processing, it is necessary in the course of the subsequent carbonization to ensure maximum adsorption of the formed secondary products – it is possible to achieve a satisfactory filtration of the investigated solutions. It is shown that the largest absolute removal of the dyes obtained after high temperature lime treatment, however, the composition of the products of disintegration to a greater extent accumulate high molecular weight compounds which deteriorate the filtration performance of solutions. In the solutions after the combination of the lime treatment in the process of carbonization is achieved the maximum effect of adsorption with the minimum remaining shares of conversion products, including high-molecular substances, which favorably affect the parameters of the filtering. The combination possibilities of the model of purification of diffusion juice with warm-hot lime treatment is limited to receive the filtered juice in the processing of raw materials with a purity of beet juice 82 % or less, you need to enter a 3.5% Cao, which is unacceptable. To ensure sustainable results of the adsorption of conversion products reducing substances and satisfactory filtering carbonated solutions are to intensify the processes of combined lime processing diffusion juice at the optimum distribution of the reagent.

    Mass media campaigns are a commonly used approach to reduce sugary drink consumption, which is linked to obesity in children and adolescents. The present study investigated the direct and mediated effects of emotional appeals in public service advertisements (PSAs) that aired between 2010 and 2012 on adolescents' intention to reduce their sugar-sweetened beverage (SSB) consumption. An online randomized experiment was conducted with a national sample of adolescent respondents ages 13 to 17 years old (N = 805). Participants were randomly assigned to 1 of 4 conditions. Three experimental conditions represented PSAs with different emotional appeals: humor, fear, and nurturance, plus a fourth control condition. The outcome was adolescents' intention to cut back on SSBs. The direct effect of fear appeals on intention was mediated through adolescents' perception of the PSAs' argument strength; perceived argument strength was also the key mediator for the indirect effects of humor and nurturance on intention. Several hypothesized mediators influenced by the appeals were not associated with intention. This is the first study to test the effect of persuasive emotional appeals used in SSB-related PSAs. The perceived strength of the PSAs' arguments is important to consider in the communication of messages designed to reduce SSB consumption.

    Radon concentration can be reduced by using polymeric compositions which fill pores inside building materials and decrease the coefficient of permeation of radon atoms and water molecules in building materials (concrete, gypsum, etc.). Polymeric silico-organic compounds were investigated and selected as the chemicals to prevent radon seeping indoors. Gas (air, Ar, 222 Rn, H 2 O) permeability of concrete and gypsum after treatment with chemicals was examined. The effect of the cement and sand types, preliminary treatment with various chemicals, type of the polymeric silico-organic compounds, time between treatments, moisture of concrete, time between the preparation of chemicals and the treatment of concrete (ageing of chemicals), time between the treatment of concrete and testing (ageing of treated concrete) were examined. Surfaces of the samples were treated by spraying. The experiments gave evidence that the chosen method of treatment of the construction materials allows reducing the coefficient of gas permeability in 200 - 400 times. Treatment of the floor, walls and ceiling of the basement of 5 buildings reduced the radon concentration in the premises of the first floor from 400-600 Bq/m 3 to the background value of 17-20 Bq/m 3

    Full Text Available This study aims to produce reducing sugar hydrolyzed from substrate, coconut coir dust pretreated by recycled ionic liquid and its combination with alkaline. The 1H NMR and FTIR were performed to ver-ify the synthesized ionic liquid methylmethylimidazolium dimethyl phosphate ([mmim][dmp]. The structure of pretreated substrates was analyzed by XRD measurement. The used ionic liquid was recy-cled twice to re-employ for substrate pretreatment. The treated- and untreated-coconut coir dust were hydrolyzed into sugars using pure cellulase. The reaction, which called an enzymatic hydrolysis, was conducted at 60 °C, pH 3, for 48 h. The yields of sugar hydrolyzed from fresh IL-pretreated, 1R*IL-pretreated and 2R*IL-pretreated substrates were of 0.19, 0.15 and 0.15 g sugar / g cellu-lose+hemicellulose, respectively. Pretreatment with NaOH or the combination of NaOH+IL resulted in yields of reducing sugars of 0.25, 0.28 g/g, respectively. When alkaline combined with the recycled ionic liquids, NaOH+1R*IL, NaOH+2R*IL in the pretreatment, the yields of sugar were relatively similar to those obtained using alkaline followed by fresh ionic liquid. If the mixture enzymes, cellu-lase+xylanase, used to liberate sugars from fresh IL-pretreated, or recycled IL-pretreated substrates, the amount of sugar (concentration or yield increased slightly compared to that employing a single cel-lulase. These findings showed that recycled IL pretreatment of the high-lignin lignocellulose, coconut coir dust, is a new prospect for the economical manufacture of fermentable sugars and biofuel in the coming years. © 2015 BCREC UNDIP.

    Childhood obesity remains a significant threat to America's children. Health care leaders have increasingly called upon oral health professionals to integrate healthy weight promotion and enhanced sugar-sweetened beverage counseling into their professional practices. The aim of this scoping review is to examine recent evidence regarding the effectiveness of primary care childhood obesity interventions that have potential for adoption by oral health professionals. Medine, and PubMed were searched from 2010 to 2016 for review articles and studies reporting patient outcomes or policy outcomes relevant to primary care childhood obesity interventions for children ages 2-11 years. Additional articles were accessed through relevant websites, journals, and references. Our screening criteria included interventions that could be adopted by oral health professionals. Forty-two articles met inclusion criteria. Effective interventions fell into four domains: family-based programs, motivational interviewing, office-based practice tools, and policy interventions. Despite strong evidence linking the consumption of sugar-sweetened beverages to childhood obesity, our review did not find evidence of primary care programs effectively targeting and reducing childhood sugary drinks. Effective primary care interventions for addressing childhood obesity have been identified, although only short-term effectiveness has been demonstrated. Dissemination of these practices as well as further research and advocacy are needed. Childhood obesity and poor oral health share many common risk factors. Additional research should focus on the benefits and feasibility of widespread interdisciplinary medical-oral health collaboration in addressing the two most prevalent diseases of childhood. © 2017 American Association of Public Health Dentistry.

  14. Silencing a sugar transporter gene reduces growth and fecundity in the brown planthopper, Nilaparvata lugens (Stål) (Hemiptera: Delphacidae).

    The brown planthopper (BPH), Nilaparvata lugens, sugar transporter gene 6 (Nlst6) is a facilitative glucose/fructose transporter (often called a passive carrier) expressed in midgut that mediates sugar transport from the midgut lumen to hemolymph. The influence of down regulating expression of sugar transporter genes on insect growth, development, and fecundity is unknown. Nonetheless, it is reasonable to suspect that transporter-mediated uptake of dietary sugar is essential to the biology of phloem-feeding insects. Based on this reasoning, we posed the hypothesis that silencing, or reducing expression, of a BPH sugar transporter gene would be deleterious to the insects. To test our hypothesis, we examined the effects of Nlst6 knockdown on BPH biology. Reducing expression of Nlst6 led to profound effects on BPHs. It significantly prolonged the pre-oviposition period, shortened the oviposition period, decreased the number of eggs deposited and reduced body weight, compared to controls. Nlst6 knockdown also significantly decreased fat body and ovarian (particularly vitellogenin) protein content as well as vitellogenin gene expression. Experimental BPHs accumulated less fat body glucose compared to controls. We infer that Nlst6 acts in BPH growth and fecundity, and has potential as a novel target gene for control of phloem-feeding pest insects.

This significant decrease in crystallinity was related to the alteration of the substrate from the cellulose I structure to the cellulose II structure. The pretreated substrates were hydrolyzed to convert them to reducing sugars by pure cellulase and xylanase,and the reaction was conducted at 60°C, pH 3, for 12 or 48 hours. The yields of sugar hydrolyzed from untreated and NaOH-pretreated substrates were 0.07 and 0.12 g sugar/g lignocellulose, respectively. Pretreatment with IL or the combination of NaOH+IL resulted in yields of reducing sugars of 0.11 and 0.13 g/g, respectively. These findings showed that IL pretreatment of the high-lignin lignocellulose is a new prospect for the economical manufacture of reducing sugars and bioethanol in the coming years.

    Adapting to changes in food availability is a central challenge for survival. Glucose is an important resource for energy production, and therefore many organisms synthesize and retain sugar storage molecules. In insects, glucose is stored in two different forms: the disaccharide trehalose and the branched polymer glycogen. Glycogen is synthesized and stored in several tissues, including in muscle and the fat body. Despite the major role of the fat body as a center for energy metabolism, the importance of its glycogen content remains unclear. Here, we show that glycogen metabolism is regulated in a tissue-specific manner under starvation conditions in the fruit fly Drosophila The mobilization of fat body glycogen in larvae is independent of Adipokinetic hormone (Akh, the glucagon homolog) but is regulated by sugar availability in a tissue-autonomous manner. Fat body glycogen plays a crucial role in the maintenance of circulating sugars, including trehalose, under fasting conditions. These results demonstrate the importance of fat body glycogen as a metabolic safeguard in Drosophila . © 2018. Published by The Company of Biologists Ltd.

    Consumer understanding of nutrition and health claims is a key aspect of current regulations in the European Union (EU). In view of this, qualitative and quantitative research techniques were used to investigate consumer awareness and understanding of product claims in the UK, focusing particularly on nutrition claims relating to sugars. Both research methods identified a good awareness of product claims. No added sugars claims were generally preferred to reduced sugars claims, and there was a general assumption that sweeteners and other ingredients would be added in place of sugars. However, there was little awareness of the level of sugar reduction and the associated calorie reduction in products when reduced sugars claims were made on pack. In focus groups, participants felt deceived if sugar reduction claims were being made without a significant reduction in calories. This was reinforced in the quantitative research which showed that respondents expected a similar and meaningful level of calorie reduction to the level of sugar reduction. The research also identified consumer confusion around the calorie content of different nutrients, including over-estimation of the calorie content of sugars. This is crucial to consumers' expectations as they clearly link sugar to calories and therefore expect a reduction in sugar content to deliver a reduction in calorie content.

    Aloe vera peel contains flavonoids, alkaloids, tannins, saponins, and sterols as its secondary metabolites. This research explores the effect of Aloe vera peel extract on blood glucose levels of alloxan-induced Wistar rats in a laboratory experimental scale. Blood glucose examination was performed by using GOD-PAP method. Twenty five 2 months old-white rat (Rattus norvegicus) male wistar strain weigh 150-200 grams body weight, and in healthy condition, was randomly divided into five groups. Those five groups were negative control group (K-), positive control group (K+), treatment group 1 (P1), treatment group 2 (P 2), and treatment group 3 (P 3). Each group was fed by standard diet and ad-libitum drinking. Treatments were given for 28 days. On the day 29, blood glucose level of all groups were analyzed. The results showed that the highest blood glucose levels in control group rat were positive (191.2 mg/dl). Aloe vera extract was able to decrease blood sugar level up to 104,6mg/dl in P3 group treatment rats (served Aloe vera extract 350 mg/kg BW/day). It comes to the conclusion that giving Aloe vera peel extract for 28 days decreases blood sugar level of hyperglycemic rat.

    We introduce a new pretreatment called co-solvent-enhanced lignocellulosic fractionation (CELF) to reduce enzyme costs dramatically for high sugar yields from hemicellulose and cellulose, which is essential for the low-cost conversion of biomass to fuels. CELF employs THF miscible with aqueous dilute acid to obtain up to 95 % theoretical yield of glucose, xylose, and arabinose from corn stover even if coupled with enzymatic hydrolysis at only 2 mgenzyme  gglucan (-1) . The unusually high saccharification with such low enzyme loadings can be attributed to a very high lignin removal, which is supported by compositional analysis, fractal kinetic modeling, and SEM imaging. Subsequently, nearly pure lignin product can be precipitated by the evaporation of volatile THF for recovery and recycling. Simultaneous saccharification and fermentation of CELF-pretreated solids with low enzyme loadings and Saccharomyces cerevisiae produced twice as much ethanol as that from dilute-acid-pretreated solids if both were optimized for corn stover. © 2015 WILEY-VCH Verlag GmbH & Co.

    Gamma irradiation enhanced the leaching of reducing sugars from barley seeds into the water in which the seeds were shaken. Treatments prior to shaking in water, such as overnight soaking in water at 5 0 C and subsequent germination in Petri dishes for 1 or 2 days at 20 0 C, showed pronounced effects on the leaching. The highest effect, which was obtained at 500 krad irradiation, was four times higher than that of the non-irradiated control. Gamma irradiation also stimulated the leaching of inorganic phosphate and slightly that of amylases from barley seeds. When seeds from which the embryos has been removed were shaken into water, no stimulating effect on the leaching of sugars was noted. These results, combined with the irradiation effect on the embryo, suggest that the stimulated leaching of reducing sugars is due to the extreme difference in sensitivity to gamma irradiation between the production of reducing sugars in the endosperm and the development and growth of the embryo.

    Full Text Available This study evaluated the clinical effects of two different amounts of melon, with a high sugar content, suddenly offered to unadapted sheep. Twelve rumem cannulated crossbred 8-months-old sheep , weighing 25 kg each, were used. These sheep had never been fed with food concentrated with sugar or fruits. The animals were kept in collective pens with a basal diet of roughage and then randomly divided into two equal groups. The sheep in the two groups received 25% and 75% of dry matter (DM of the diet the crushed melon, administered by the rumen cannula. Physical examination and measurement of rumen fluid pH was performed at the following times: 0, 3, 6, 12, 18 and 24 h. The animals of G25% did not present clinical signs despite subacute acidosis expected after administration of the melon. However, in the G75%, sheep developed clinical manifestation indicative of lactic acidosis with rumen fluid pH lower than 5.0 from T6h, but did not present with dehydration. In sheep from G75 %, tachycardia was observed at 3 h and continued until the end of the study; tachypnea was also observed at 3 h, which was caused by increased abdominal circumference. Based on the results obtained, the supplementation of high amounts of melon (75% DM in the diet is not recommended for sheep, although the use of 25% DM is safe. However, greater amounts of this fruit could be used in the diet of sheep with gradual adaptation to the substrate.

    The reduction of free or added sugar intake (sugars added to food and drinks as a sweetener) is almost universally recommended to reduce the risk of obesity-related diseases and dental caries. The World Health Organisation recommends intakes of free sugars of less than 10% of energy intake. However, estimating and monitoring intakes at the population level is challenging because free sugars cannot be analytically distinguished from naturally occurring sugars and most national food composition databases do not include data on free or added sugars. We developed free and added sugar estimates for the New Zealand (NZ) food composition database (FOODfiles 2010) by adapting a method developed for Australia. We reanalyzed the 24 h recall dietary data collected for 4721 adults aged 15 years and over participating in the nationally representative 2008/09 New Zealand Adult Nutrition Survey to estimate free and added sugar intakes. The median estimated intake of free and added sugars was 57 and 49 g/day respectively and 42% of adults consumed less than 10% of their energy intake from free sugars. This approach provides more direct estimates of the free and added sugar contents of New Zealand foods than previously available and will enable monitoring of adherence to free sugar intake guidelines in future.

    Eight monosaccharides were found to be released from both tall and short forms of Spartina alterniflora during tidal submergence including: 2-d ribose, rhamnose, ribose, mannose, arabinose, fructose, galactose and xylose. Glucose was not detected in the leachate of either growth form. Two additional monosaccharides were found but were not identified. Losses of total reducing sugars (TRS) and total dissolved organic carbon (TDOC) ranged from 14-54 μgCg -1 dry wth -1 and 42 to 850 μgCg -1 dry wth -1, respectively. Losses of individual monosaccharides were generally <5μgCg -1 dry wth -1 and varied from 0·5-17 μgCg -1 dry wth -1. Differences were observed in seasonal patterns of losses between tall and short Spartina. Tall Spartina TRS losses peaked in midsummer, while in short Spartina TRS losses peaked in the spring and fall. TDOC losses in both tall and short Spartina followed similar patterns with peak losses occurring in the spring and fall. Periods of net uptake of TDOC were observed in both growth forms in midsummer. Uptake rates varied from 142-930 μgCg -1 dry wth -1. Estimated annual losses of TDOC from tall and short Spartina were between 100-150 and 5-10 gCm -2 year -1, respectively. The magnitude and seasonal pattern of TDOC losses reported here support Turner's conclusions that losses of labile DOM from Spartina are substantial in Georgia salt marshes and related to seasonal patterns of estuarine metabolism.

    The rapid increase in the prevalence of obesity worldwide has been partially attributed to the overconsumption of added sugars. Recent guidelines call for limiting the consumption of simple sugars to less than 10% of daily caloric consumption. High intensity sweeteners are regulated as food additives and include aspartame, acesulfame-k, neotame, saccharin, sucralose, cyclamate and alitame. Steviol glycosides and Luo Han Guo fruit extracts are high intensity sweeteners that are designated as generally recognized as safe (GRAS). Commonly used non-caloric artificial sweeteners may have unfavorable effect on health including glucose intolerance and failure to cause weight reduction. The nutritive sweeteners include sugar alcohols such as sorbitol, xylitol, lactitol, mannitol, erythritol, trehalose and maltitol. Naturally occurring rare sugars have recently emerged as an alternative category of sweeteners. These monosaccharides and their derivatives are found in nature in small quantities and lack significant calories. This category includes d-allulose (d-psicose), d-tagatose, d-sorbose and d-allose. Limiting consumption of any sweetener may well be the best health advice. Identifying natural sweeteners that have favorable effects on body weight and metabolism may help achieving the current recommendations of restricting simple sugar consumption.

  12. Expression of Arabidopsis FCS-Like Zinc finger genes is differentially regulated by sugars, cellular energy level, and abiotic stress

    2015-09-01

    Full Text Available Cellular energy status is an important regulator of plant growth, development, and stress mitigation. Environmental stresses ultimately lead to energy deficit in the cell which activates the SNF1-RELATED KINASE 1 (SnRK1 signaling cascade which eventually triggering a massive reprogramming of transcription to enable the plant to survive under low-energy conditions. The role of Arabidopsis thaliana FCS-Like Zinc finger (FLZ gene family in energy and stress signaling is recently come to highlight after their interaction with kinase subunits of SnRK1 were identified. In a detailed expression analysis in different sugars, energy starvation, and replenishment series, we identified that the expression of most of the FLZ genes is differentially modulated by cellular energy level. It was found that FLZ gene family contains genes which are both positively and negatively regulated by energy deficit as well as energy-rich conditions. Genetic and pharmacological studies identified the role of HEXOKINASE 1- dependent and energy signaling pathways in the sugar-induced expression of FLZ genes. Further, these genes were also found to be highly responsive to different stresses as well as abscisic acid. In over-expression of kinase subunit of SnRK1, FLZ genes were found to be differentially regulated in accordance with their response towards energy fluctuation suggesting that these genes may work downstream to the established SnRK1 signaling under low-energy stress. Taken together, the present study provides a conceptual framework for further studies related to SnRK1-FLZ interaction in relation to sugar and energy signaling and stress response.

    Excessive consumption of added sugars in the human diet has been associated with obesity, type 2 diabetes (T2D), coronary heart disease (CHD) and other elements of the metabolic syndrome. Recent studies have shown that non-alcoholic fatty liver disease (NAFLD) is a critical pathway to metabolic syndrome. This model assesses the health and economic benefits of interventions aimed at reducing intake of added sugars. Using data from US National Health Surveys and current literature, we simulated an open cohort, for the period 2015-2035. We constructed a microsimulation model with Markov chains for NAFLD (including steatosis, non-alcoholic steatohepatitis (NASH), cirrhosis and hepatocellular carcinoma (HCC)), body mass index, T2D and CHD. We assessed reductions in population disease prevalence, disease-attributable disability-adjusted life years (DALYs) and costs, with interventions that reduce added sugars consumption by either 20% or 50%. The model estimated that a 20% reduction in added sugars intake will reduce prevalence of hepatic steatosis, NASH, cirrhosis, HCC, obesity, T2D and CHD. Incidence of T2D and CHD would be expected to decrease by 19.9 (95% CI 12.8 to 27.0) and 9.4 (95% CI 3.1 to 15.8) cases per 100 000 people after 20 years, respectively. A 20% reduction in consumption is also projected to annually avert 0.767 million (M) DALYs (95% CI 0.757M to 0.777M) and a total of US$10.3 billion (B) (95% CI 10.2B to 10.4B) in discounted direct medical costs by 2035. These effects increased proportionally when added sugars intake were reduced by 50%. The decrease in incidence and prevalence of disease is similar to results in other models, but averted costs and DALYs were higher, mainly due to inclusion of NAFLD and CHD. The model suggests that efforts to reduce consumption of added sugars may result in significant public health and economic benefits. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Objective: To approach the correlation between the bone density measured by quantitative CT and the blood sugar level of the aged patients with non-insulin-dependent diabetes mellitus, and observe the effects of the blood sugar level on the bone density. Methods: The lumbar bone densities and the blood sugar levels of 160 aged patients with non-insulin-dependent diabetes mellitus (hyperglycemia group 80 cases, euglycemia group 80 cases ) and the healthy aged people (80 cases) were detected by quantitative CT and serum biochemical detection; the correlation between the blood sugar level and the bone density and the osteoporosis occurrence status of aged people in various groups were analyzed. Results: The bone density in the non-insulin-dependent diabetes and hyperglycemia group was lower than those in normal (control) group and non-insulin-dependent diabetes and euglycemia group (P<0.05); the morbility of osteoporosis in the non-insulin-dependent diabetes and hyperglycemia group was higher than those in normal (control) group and non-insulin-dependent diabetes and euglycemia group (P<0.05); negative correlation was found between the bone density and the blood sugar level (aged male group: r=-0.7382, P=0.0013; aged female group: r=-0.8343, P=0.0007). Conclusion: The blood sugar level affects the bone density of the aged patients with non-insulin-dependent diabetes mellitus; the higher the blood sugar level, the lower the bone density. The non-insulin-dependent diabetes aged patients with hyperglycemia have the liability of osteoporosis. (authors)

    2016-01-01

    The term 'added sugars' refers to sugars and syrup added to foods during processing or preparation, and sugars and syrups added at the table. Calls to limit the daily intakes of added sugars and its sources arose from evidence analysed by WHO, the American Heart Association and other organizations. The present review examined the best available evidence regarding levels of added sugar consumption among different age and sex groups in Malaysia and sources of added sugars. Information was extracted from food balance sheets, household expenditure surveys, nutrition surveys and published studies. Varying results emerged, as nationwide information on intake of sugar and foods with added sugar were obtained at different times and used different assessment methods. Data from the 2003 Malaysian Adult Nutrition Survey (MANS) using food frequency questionnaires suggested that on average, Malaysian adults consumed 30 grams of sweetened condensed milk (equivalent to 16 grams sugar) and 21 grams of table sugar per day, which together are below the WHO recommendation of 50 grams sugar for every 2000 kcal/day to reduce risk of chronic disease. Published studies suggested that, for both adults and the elderly, frequently consumed sweetened foods were beverages (tea or coffee) with sweetened condensed milk and added sugar. More accurate data should be obtained by conducting population-wide studies using biomarkers of sugar intake (e.g. 24-hour urinary sucrose and fructose excretion or serum abundance of the stable isotope 13C) to determine intake levels, and multiple 24 hour recalls to identify major food sources of added sugar.

    Mesotoga prima strain PhosAc3 is a mesophilic representative of the phylum Thermotogae comprising only fermentative bacteria so far. We show that while unable to ferment glucose, this bacterium is able to couple its oxidation to reduction of elemental sulfur. We demonstrate furthermore that M. prima strain PhosAc3 as well as M. prima strain MesG1 and Mesotoga infera are able to grow in syntrophic association with sulfate-reducing bacteria (SRB) acting as hydrogen scavengers through interspecies hydrogen transfer. Hydrogen production was higher in M. prima strain PhosAc3 cells co-cultured with SRB than in cells cultured alone in the presence of elemental sulfur. We propose that the efficient sugar-oxidizing metabolism by M. prima strain PhosAc3 in syntrophic association with a hydrogenotrophic sulfate-reducing bacterium can be extrapolated to all members of the Mesotoga genus. Genome comparison of Thermotogae members suggests that the metabolic difference between Mesotoga and Thermotoga species (sugar oxidation versus fermentation) is mainly due to the absence of the bifurcating [FeFe]-hydrogenase in the former. Such an obligate oxidative process for using sugars, unusual within prokaryotes, is the first reported within the Thermotogae. It is hypothesized to be of primary ecological importance for growth of Mesotoga spp. in the environments that they inhabit. © 2017 Society for Applied Microbiology and John Wiley & Sons Ltd.

    Full Text Available Although the 2015 Dietary Guidelines Advisory Committee concluded that there was moderate evidence that substituting sugar-containing sweeteners with low-calorie sweeteners (LCS reduces calorie intake and weight, dietary recommendations encourage substituting only water for sugar-sweetened beverages during weight management. This cross-sectional study evaluated the relation of water and no- and low-calorie sweetened beverage (LCSB intake with nutrient intakes and prediabetes criteria using data from the National Health and Nutrition Examination Survey (NHANES 2001–2012 in 25,817 adults that were free of diabetes. Although linear trends were observed with both beverages, higher LCSB intake was associated with significantly lower consumption of carbohydrates (−9.1 g/day vs. −1.4 g/day, total sugars (−10.9 g/day vs. −2.2 g/day, and added sugars (−2.0 tsp eq vs. −0.8 tsp eq than those associated with higher water intake. Higher intake of both beverages was significantly associated with lower insulin levels (p < 0.01; however, higher intake of LCSB was also associated with lower hemoglobin A1c (HbA1c and lower homeostatic model assessment of insulin resistance (HOMA-IR (p < 0.01. We observed lower odds ratios for elevated HbA1c (adjusted odds ratio [OR] 0.79, 95% CI 0.64–0.98, HOMA-IR (0.68, 0.53–0.87, and insulin levels (0.63, 0.49–0.80 in LCSB among the higher (2+ servings intake group compared to the lowest (<1 serving intake group. Contrary to conventional wisdom, LCSB consumption was associated with equal, if not better, dietary intake and glycemic response than water consumption. Although observational in nature, these results contribute to the growing body of evidence from human studies suggesting that in addition to water, LCSBs can also be sensible choices for reducing sugars and carbohydrate intake, with no adverse associations to measures of glycemic response.

  3. Comparison of sugar molecule decomposition through glucose and fructose: a high-level quantum chemical study.

    Efficient chemical conversion of biomass is essential to produce sustainable energy and industrial chemicals. Industrial level conversion of glucose to useful chemicals, such as furfural, hydroxymethylfurfural, and levulinic acid, is a major step in the biomass conversion but is difficult because of the formation of undesired products and side reactions. To understand the molecular level reaction mechanisms involved in the decomposition of glucose and fructose, we have carried out high-level quantum chemical calculations [Gaussian-4 (G4) theory]. Selective 1,2-dehydration, keto-enol tautomerization, isomerization, retro-aldol condensation, and hydride shifts of glucose and fructose molecules were investigated. Detailed kinetic and thermodynamic analyses indicate that, for acyclic glucose and fructose molecules, the dehydration and isomerization require larger activation barriers compared to the retro-aldol reaction at 298 K in neutral medium. The retro-aldol reaction results in the formation of C2 and C4 species from glucose and C3 species from fructose. The formation of the most stable C3 species, dihydroxyacetone from fructose, is thermodynamically downhill. The 1,3-hydride shift leads to the cleavage of the C-C bond in the acyclic species; however, the enthalpy of activation is significantly higher (50-55 kcal/mol) than that of the retro-aldol reaction (38 kcal/mol) mainly because of the sterically hindered distorted four-membered transition state compared to the hexa-membered transition state in the retro-aldol reaction. Both tautomerization and dehydration are catalyzed by a water molecule in aqueous medium; however, water has little effect on the retro-aldol reaction. Isomerization of glucose to fructose and glyceraldehyde to dihydroxyacetone proceeds through hydride shifts that require an activation enthalpy of about 40 kcal/mol at 298 K in water medium. This investigation maps out accurate energetics of the decomposition of glucose and fructose molecules

    To examine behavioural intention to reduce soda consumption after exposure to the Choose Health LA 'Sugar Pack' campaign in Los Angeles County, California, USA. A cross-sectional street-intercept survey was conducted to assess knowledge, attitudes, health behaviours and behavioural intentions after exposure to the 'Sugar Pack' campaign. A multivariable regression analysis was performed to examine the relationships between the amount of soda consumed and self-reported intention to reduce consumption of non-diet soda among adults who saw the campaign. Three pre-selected Los Angeles County Metro bus shelters and/or rail stops with the highest number of 'Sugar Pack' campaign advertisement placements. Riders of the region's Metro buses and railways who were the intended audience of the campaign advertisements. The overall survey response rate was 56 % (resulting n 1041). Almost 60 % of respondents were exposed to the advertisements (619/1041). The multivariable logistic regression analysis suggested that the odds of reporting intention to reduce soda consumption among moderate consumers (1-6 sodas/week) were 1·95 times greater than among heavy consumers (≥1 soda/d), after controlling for clustering and covariates. Respondents with less than a high-school education and who perceived sugary beverage consumption as harmful also had higher odds; in contrast, respondents aged ≥65 years had lower odds. Results suggest that future campaigns should be tailored differently for moderate v. heavy consumers of soda. Similar tailoring strategies are likely needed for younger groups, for those with less educational attainment and for those who do not perceive consumption of soda as harmful.

    Full Text Available Cercospora leaf spot (CLS is one of the most serious leaf diseases for sugar beet (Beta vulgaris L. worldwide. The breeding of sugar beet cultivars with both high CLS resistance and high yield is a major challenge for breeders. In this study, we report the nuclear magnetic resonance (NMR-based metabolic profiling of field-grown leaves for a subset of sugar beet genotypes harbouring different levels of CLS resistance. Leaves were collected from 12 sugar beet genotypes at four time points: seedling, early growth, root enlargement, and disease development stages. 1H-NMR spectra of foliar metabolites soluble in a deuterium-oxide (D2O-based buffer were acquired and subjected to multivariate analyses. A principal component analysis (PCA of the NMR data from the sugar beet leaves shows clear differences among the growth stages. At the later time points, the sugar and glycine betaine contents were increased, whereas the choline content was decreased. The relationship between the foliar metabolite profiles and resistance level to CLS was examined by combining partial least squares projection to latent structure (PLS or orthogonal PLS (OPLS analysis and univariate analyses. It was difficult to build a robust model for predicting precisely the disease severity indices (DSIs of each genotype; however, GABA and Gln differentiated susceptible genotypes (genotypes with weak resistance from resistant genotypes (genotypes with resistance greater than a moderate level before inoculation tests. The results suggested that breeders might exclude susceptible genotypes from breeding programs based on foliar metabolites profiled without inoculation tests, which require an enormous amount of time and effort.

    This study investigated acrylamide and 5-hydroxymethylfurfural (HMF) formation during biscuit baking. Four types of wheat flour with different molar ratios of total fructose and glucose to asparagine were investigated. Nevertheless, the molar ratio in all four biscuit doughs exceeded one after proofing due to enzyme action. Data obtained after baking were used to develop a mechanistic model, based on the asparagine-related pathway, for acrylamide and HMF formation in the four baked biscuit types. Asparagine reacted with fructose to form a Schiff base before decarboxylation to produce acrylamide without Amadori rearrangement product and sugar fragmentation. Fructose contributed considerably to acrylamide formation and to HMF formation via caramelization in all four biscuit types. No clear correlation was found between acrylamide and HMF in baked biscuits, nor between asparagine and the sum of glucose and fructose concentrations in the wheat flour.

    Full Text Available The aim of the study was to evaluate the effect of feeding two levels of crude protein (CP (low: 142 g CP/kg DM; and high: 156 g CP/kg DM and two nitrogen sources (soybean meal and urea to dairy cows using sugar cane as forage on microbial protein synthesis, the composition of the milk nitrogen fraction, nitrogen (N balance and blood parameters. Twelve Holstein cows with an average milk yield of 22.0 ± 2.3 kg/day, and with 235 ± 40 days in milk were included in this study. The animals were grouped into three balanced and contemporary 4x4 Latin squares for an experimental period of 21 days. On the 15th day of each period, milk and urine samples were collected for microbial protein synthesis determination. Total excretion of urine (L/day, milk urea nitrogen (MUN and blood urea were higher for the diets with high CP, regardless of the nitrogen source. Nitrogen efficiency was higher for cows fed diets with low CP. Cows in the final third of lactation can be fed diets with reduced CP levels, regardless of the nitrogen source, soybean meal or urea, without influencing the synthesis of microbial protein or the composition of the nitrogen fraction of milk.

    Bayesian statistics proposes an approach that is very flexible in the number of samples and distribution of data. Bayesian Mixture Model (BMM) is a Bayesian approach for multimodal models. Diabetes Mellitus (DM) is more commonly known in the Indonesian community as sweet pee. This disease is one type of chronic non-communicable diseases but it is very dangerous to humans because of the effects of other diseases complications caused. WHO reports in 2013 showed DM disease was ranked 6th in the world as the leading causes of human death. In Indonesia, DM disease continues to increase over time. These research would be studied patterns and would be built the BMM models of the DM data through simulation studies where the simulation data built on cases of blood sugar levels of DM patients in RSUD Saiful Anwar Malang. The results have been successfully demonstrated pattern of distribution of the DM data which has a normal mixture distribution. The BMM models have succeed to accommodate the real condition of the DM data based on the data driven concept.

    Sugar reduction in processed foods is a pressing and complex problem, as sugars contribute important sensory and physical properties to foods. Composed of sugars and lipids, caramel coating systems, like the coating in caramel popcorns, exemplify this challenge. In order to probe the feasibility and consequences of sugar reduction, both sensory and physical properties were measured for 3 types of caramel coating systems. Four commonly used sugar alcohols, isomalt, maltitol, mannitol, and sorbitol, with different thermal properties and relative sweetness values were chosen to replace sugar in the caramel coating systems at 25% and 50% sugar reduction levels. Full sugar (control) and reduced sugar caramel coating samples were prepared in duplicate. Ten trained panelists participated in a 6-wk descriptive analysis panel to define and quantify the intensity of important sensory characteristics. All 24 sensory terms generated by the panel differed significantly across caramel type and sugar replacer. Thermal properties were measured through differential scanning calorimetry, and textural properties were measured through texture profile analysis. Replacement of sugar with sugar alcohols was found to decrease the glass transition temperature and systematically alter the hardness and resilience of caramel samples. Principal component analysis of sensory and physical data revealed that caramel coating type dictates caramel aroma, aroma by mouth, taste, and aftertaste, while sugar replacer and replacement level dictate texture. This research represents the first comprehensive study of the effects of sugar reduction in a caramel coating system and suggests successful strategies for sugar reduction and key parameters to control in reduced sugar systems. © 2017 Institute of Food Technologists®.

    Full Text Available Chronic inflammation associated with inflammatory bowel disease (IBD results in increased oxidative stress that damages the colonic microenvironment. Low levels of serum bilirubin, an endogenous antioxidant, have been associated with increased risk for Crohn's disease (CD. Therefore, the aim of this study was to examine whether total serum bilirubin levels are associated with ulcerative colitis (UC. We identified a retrospective case-control population (n = 6,649 from a single tertiary care center, Penn State Hershey Medical Center (PSU and a validation cohort (n = 1,996 from Virginia Commonwealth University Medical Center (VCU. Cases were age- and sex-matched to controls (PSU: CD n = 254, UC n = 187; VCU: CD n = 233, UC n = 124. Total serum bilirubin levels were obtained from de-identified medical records and segregated into quartiles. Logistic regression analysis was performed on each quartile of total serum bilirubin compared to the last quartile (highest bilirubin levels to determine the association of total serum bilirubin with UC. Similar to CD patients, UC patients demonstrated reduced levels of total serum bilirubin compared to controls at PSU and VCU. The lowest quartile of total serum bilirubin was independently associated with UC for the PSU (OR: 1.98 [95% CI: 1.09-3.63] and VCU cohorts (OR: 6.07 [95% CI: 3.01-12.75]. Lower levels of the antioxidant bilirubin may reduce the capability of UC patients to remove reactive oxygen species leading to an increase in intestinal injury. Therapeutics that reduce oxidative stress may be beneficial for these patients.

    2013-12-01

    Employees working in cubicles of open-plan offices in Indonesia were studied in regard to their perception on the ability of indoor greenery to reduce noise levels. Sansevieria trifasciata and Scindapsus sp were used. Each was placed in the cubicle and noise levels were measured without plants, with Sansevieria, and with Scindapsus in place. The meters showed very insignificant difference. However, responses to surveys indicated a perception of lower noise in the presence of greenery. This seemed to be supported by prior knowledge and preconception and may be useful in creating a "quieter" indoor environment.

    Is consumption of sugar-sweetened beverages (SSB) associated with semen quality? Higher consumption of SSB was associated with lower sperm motility among healthy, young men. The existing literature on the potential role of SSBs on male reproductive function is scarce and primarily focused on the relation between caffeinated beverages and semen quality. However, a rodent model suggests that SSBs may hamper male fertility. The Rochester Young Men's Study; a cross-sectional study of 189 healthy young men carried out at the University of Rochester during 2009-2010. Men aged 18-22 years provided semen and blood samples, underwent a physical examination and completed a previously validated food frequency questionnaire (FFQ). Linear regression was used to analyze the association of SSBs with sperm parameters and reproductive hormone levels while adjusting for potential confounders. SSB intake was inversely related to progressive sperm motility. Men in the highest quartile of SSB intake (≥1.3 serving/day) had 9.8 (95% CI: 1.9,17.8) percentage units lower progressive sperm motility than men in the lowest quartile of intake (beverages. While our findings are in agreement with recent experimental data in rodents, more studies are required to draw conclusions on the relation of SSB with semen quality or male infertility.

  6. [Phytosterols: another way to reduce LDL cholesterol levels].

    Science.gov (United States)

    Bitzur, Rafael; Cohen, Hofit; Kamari, Yehuda; Harats, Dror

    2013-12-01

    Phytosterols are sterols found naturally in various oils from plants. Phytosterols compete with cholesterol for a place in the mixed micelles, needed for cholesterol absorption by the small intestine. As a result, cholesterol absorption, either from food or from bile salts is lowered by about 50%, leading to a towering of about 10% of blood cholesterol level, despite an increase in hepatic cholesterol synthesis. This reduction is achieved when phytosterols are given both as monotherapy, and in addition to statin therapy. The average Western diet contains about 400-800 mg of phytosterols per day, while the dose needed for lowering the blood cholesterol level is about 2-3 grams per day. Therefore, for the purpose of reducing blood cholesterol, they should be given either as phytosterol-enriched food or as supplements. The reduction in the level of LDL-choLesterol achieved with phytosterols may reduce the risk of coronary disease by about 25%. Hence, the American Heart Association recommended the consumption of phytosterols, as part of a balanced diet, for towering blood cholesterol levels.

    Full Text Available Experiments were carried out at El-Riad district, Kafr El-Sheikh Governorate in two successive growing seasons (2009/10 and 2010/11 to study the effect of intercropping of faba bean, maize and cabbage with sugar beet on the population density of Empoasca spp. (nymphs and adults, Aphis spp. (nymphs and adults, Bemisia tabaci (adults, Pegomyia mixta (eggs and larvae, Cassida vittata (larvae, pupae and adults and predators in sugar beet plantations compared with the non-intercropped plants and the resulting yield. The toxicity of certain compounds: fenitrothion, super misrona, sour orange oil, acidless orange oil, and Bermectine in reducing the population density of P. mixta and C. vittata larvae infesting sugar beet was evaluated. The rate of infestation was higher in the sole sugar beet plants than in those intercropped with faba bean, maize and cabbage plants which caused reduction of sucking pests and P. mixta eggs in the two seasons. The intercropping of faba bean plants led to higher infestation rate of P. mixta larvae in the two seasons and C. vittata (larvae, pupae and adults in the first season. The intercropping with maize led to a higher population density of Chrysoperla carnea, Paederus alfierii and Scymnus spp. in the two seasons. Low population density of true spiders was observed in sole sugar beet (control when compared with faba bean, maize and cabbage plants intercropped in the two seasons. Concerning the obtained root yield, the intercropping with maize and cabbage plants reduced the resultant yield of sugar beet roots in the two seasons. Bermectine and fenitrothion were the most effective toxicants followed by super misrona and then, sour orange that induced the lowest reduction in P. mixta larvae. Also, fenitrothion and Bermectine were the most potent compounds in reducing the population density of C. vittata larvae followed by super misrona and then, plant oil extracts.

    The objective of the present study was to test the effectiveness of financial incentives and traffic-light labels to reduce purchases of sugar-sweetened beverages in a community supermarket. In this randomized controlled trial, after a 2-month baseline period (February-March 2014), in-store traffic-light labels were posted to indicate healthy (green), less healthy (yellow) or unhealthy (red) beverages. During the subsequent five months (April-August 2014), participants in the intervention arm were eligible to earn a $US 25 in-store gift card each month they refrained from purchasing red-labelled beverages. Urban supermarket in Chelsea, MA, USA, a low-income Latino community. Participants were customers of this supermarket who had at least one child living at home. A total of 148 customers (n 77 in the intervention group and n 71 in the control group) were included in the final analyses. Outcomes were monthly in-store purchases tracked using a store loyalty card and self-reported consumption of red-labelled beverages. Compared with control participants, the proportion of intervention participants who purchased any red-labelled beverages decreased by 9 % more per month (P=0·002). More intervention than control participants reduced their consumption of red-labelled beverages (-23 % v. -2 % for consuming ≥1 red beverage/week, P=0·01). Overall, financial incentives paired with in-store traffic-light labels modestly reduced purchase and consumption of sugar-sweetened beverages by customers of a community supermarket.

    The safety of rare sugar syrup obtained from high-fructose corn syrup under slightly alkaline conditions was studied. Mutagenicity of rare sugar syrup was assessed by a reverse mutation assay using Salmonella typhimurium and Escherichia coli, and an in vitro chromosomal aberration assay using Chinese hamster lung cell line (CHL/IU). No mutagenicity of rare sugar syrup was detected under these experimental conditions. Oral administration of single dose (15,000 mg/kg) of rare sugar syrup to rats caused no abnormalities, suggesting no adverse effect of rare sugar syrup. In humans, the acute non-effect level of rare sugar syrup for causing diarrhea was estimated as 0.9 g/kg body weight as dry solid base in both males and females.

    Some dietary factors could inhibit lead toxicity. The aim of this study was to evaluate the effect of dietary compounds rich in unsaturated fatty acids (FA) on blood lead level, lipid metabolism, and vascular reactivity in rats. Serum metallothionein and organs' lead level were evaluated with the aim of assessing the possible mechanism of unsaturated FA impact on blood lead level. For three months, male Wistar rats that were receiving drinking water with (100 ppm Pb) or without lead acetate were supplemented per os daily with virgin olive oil or linseed oil (0.2 mL/kg b.w.) or egg derived lecithin fraction: “super lecithin” (50 g/kg b.w.). Mesenteric artery was stimulated ex vivo by norepinephrine (NE) administered at six different doses. Lecithin supplementation slightly reduced pressor responses of artery to NE. Lead administered to rats attenuated the beneficial effect of unsaturated FA on lipid metabolism and vascular reactivity to adrenergic stimulation. On the other hand, the super lecithin and linseed oil that were characterized by low omega-6 to omega-3 ratio (about 1) reduced the blood lead concentration. This effect was observed in lead poisoned rats (p < 0.0001) and also in rats nonpoisoned with lead (p < 0.05). PMID:26075218

    This study evaluates a citywide media campaign that targeted reducing sugar-sweetened beverage (SSB) consumption as a strategy for addressing obesity. Rolling cross-sectional survey data, collected before and during the media campaign, with 1367 parents to assess exposure to and effect of a televised public service advertisement (TV PSA) developed using a reasoned action approach. Televised public service advertisement campaign created by the Philadelphia Department of Public Health and disseminated on cable television channels within the Philadelphia market. Philadelphia parents/primary caregivers with a child between the ages of 3 and 16. Linear regression analysis shows that exposure to the TV PSA was significantly associated with intention to substitute nonsugary drinks for SSBs for the parent ( P = .04) and the child ( P = .02). The effect of exposure on intention to reduce child's SSB consumption increased the longer the campaign was in the field. Exposure was also significantly associated with the belief that reducing SSB consumption decreases the risk of diabetes ( P = .04) and was significantly negatively related to the belief that reducing SSB consumption would make mealtimes less enjoyable ( P = .04). These findings suggest that a theory-based mass media campaign can achieve positive changes in intention related to SSB consumption by changing relevant and salient underlying beliefs.

    Full Text Available Wine Pesticide residues, even when below grape regulatory limit, are a concern for consumers and have an impact on the export potential of wine in certain markets. A consortium of European SMEs (www.adfimax.com has developed a product that reduces the level of mycotoxins and pesticides in wine while keeping all other wine parameter identical. The product is derived from renewable vegetable fiber. The production process includes both activation and micronisation. The usage recommendation is to substitute only the pre-coat, typically perlite, by the product at 1 or 1.5 kg⋅m−2 without changing the other layer (body feed typically kieselguhr. This paper describes the results of numerous industrial trials that were performed in France, Luxemburg, Germany and Spain. The impact of the product on the wine oenological characteristics was evaluated for different wine (white, red and rosé in different countries and for different grape variety (including Cabernet sauvignon, Merlot and Gamay. Results showed a reduction of the test wine pesticide level of 50% to 60% for all pesticides compared to the blank. Level of pesticide analyzed in the cake where extremely high at a level of a 1,000 times greater than the filtered wine showing the ability of the product to selectively capture the pesticides molecules.

    In the present study, one hundred pure and adulterated honey samples obtained from feeding honeybee colonies with different levels (5, 20 and 100 L/colony) of various commercial sugar syrups including High Fructose Corn Syrup 85 (HFCS-85), High Fructose Corn Syrup 55 (HFCS-55), Bee Feeding Syrup (BFS), Glucose Monohydrate Sugar (GMS) and Sucrose Sugar (SS) were evaluated in terms of the δ(13)C value of honey and its protein, difference between the δ(13)C value of protein and honey (Δδ(13)C), and C4% sugar ratio. Sugar type, sugar level and the sugar type*sugar level interaction were found to be significant (Phoney, Δδ(13)C (protein-honey), and C4% sugar ratio were used as criteria according to the AOAC standards. However, it was possible to detect the adulteration by using the same criteria in the honeys taken from the 20 and 100 L/colony of HFCS-85 and the 100L/colony of HFCS-55. Adulteration at low syrup level (20 L/colony) was more easily detected when the fructose content of HFCS syrup increased. As a result, the official methods (AOAC, 978.17, 1995; AOAC, 991.41, 1995; AOAC 998.12, 2005) and Internal Standard Carbon Isotope Ratio Analysis could not efficiently detect the indirect adulteration of honey obtained by feeding the bee colonies with the syrups produced from C3 plants such as sugar beet (Beta vulgaris) and wheat (Triticium vulgare). For this reason, it is strongly needed to develop novel methods and standards that can detect the presence and the level of indirect adulterations. Copyright © 2014 Elsevier Ltd.

    2002-01-01

    In order to mitigate indoor radon level, a new fast-setting, solvent-free, polyurethane-based coating material was developed. The permeability of radon gas in the new material was estimated with a simple radon permeation test system set up in this study. It was found that the permeation velocity depended on the thickness of the coating material, and a thickness of 2.0 mm of the coating material seems sufficient for preventing radon permeation. The permeability of radon in the coating material was estimated to be (2.2± 0.8)x10 -10 m 2 ·s -1 for a thickness of about 1.0 mm. The value is much lower than those reported for membrane materials and caulking compounds. For its performance test, the coating material was used in an existing room with high radon level. By spraying a thickness of 1.5 mm of the material, the indoor radon level reduced by about 80%

    Full Text Available This work evaluated the inclusion of phytase in diets with reduced nonphytate phosphorus (NPP levels in relation to the performance and carcass yield of broilers and litter characteristics. The experimental design was completely randomized in a 2 x 3 factorial arrangement – two phytase levels (0 and 25U/kg and three NPP levels (100, 85 and 70% of the requirement, in a total of six treatments with fi ve replicates. The reduction of the NPP to 70% of the requirement decreased the weight gain and feed intake and increased the feed:gain ratio. Phytase inclusion increased the weight gain and the feed intake at 21 days. The NPP x phytase interaction was signifi cant with regard to the weight gain at 42 days. The reduction of NPP to 70% diminished the feed intake at 42 days and increased the liver and heart relative weight. Nitrogen content was lower in the litter of broilers fed diets with phytase and decreased phosphorus content, due to the NPP reduction in the diets. It was concluded that diets with 85% of NPP, supplemented with 25U/kg of phytase, can be used with no negative effect on performance or carcass and litter characteristics.

    Existing pressure equipment in High Level Waste does not have a documented technical baseline. Based on preliminary reviews, the existing equipment seems to be based on system required capacity instead of system capability. A planned approach to establish a technical baseline began September 1992 and used the Works Management System preventive maintenance schedule. Several issues with relief valves being undersized on steam reducing stations created a need to determine the risk of maintaining the steam in service. An Action Plan was developed to evaluate relief valves that did not have technical baselines and provided a path forward for continued operation. Based on Action Plan WER-HLE-931042, the steam systems will remain in service while the designs are being developed and implemented

    Oxidative damage is implicated in the etiology of cancer, cardiovascular disease, and other degenerative disorders. Recent nutritional research has focused on the antioxidant potential of foods, while current dietary recommendations are to increase the intake of antioxidant-rich foods rather than supplement specific nutrients. Many alternatives to refined sugar are available, including raw cane sugar, plant saps/syrups (eg, maple syrup, agave nectar), molasses, honey, and fruit sugars (eg, date sugar). Unrefined sweeteners were hypothesized to contain higher levels of antioxidants, similar to the contrast between whole and refined grain products. To compare the total antioxidant content of natural sweeteners as alternatives to refined sugar. The ferric-reducing ability of plasma (FRAP) assay was used to estimate total antioxidant capacity. Major brands of 12 types of sweeteners as well as refined white sugar and corn syrup were sampled from retail outlets in the United States. Substantial differences in total antioxidant content of different sweeteners were found. Refined sugar, corn syrup, and agave nectar contained minimal antioxidant activity (sugar had a higher FRAP (0.1 mmol/100 g). Dark and blackstrap molasses had the highest FRAP (4.6 to 4.9 mmol/100 g), while maple syrup, brown sugar, and honey showed intermediate antioxidant capacity (0.2 to 0.7 mmol FRAP/100 g). Based on an average intake of 130 g/day refined sugars and the antioxidant activity measured in typical diets, substituting alternative sweeteners could increase antioxidant intake an average of 2.6 mmol/day, similar to the amount found in a serving of berries or nuts. Many readily available alternatives to refined sugar offer the potential benefit of antioxidant activity.

  1. Strategy for reducing ozone levels in the northeast United States

    International Nuclear Information System (INIS)

    Bradley, M.

    1992-01-01

    In the northeast USA, ozone episodes are frequent during the summer; most of these episodes last 3-4 days. The duration and frequency of these episodes is mainly determined by weather conditions. The persistence of ozone episodes in the region is explained by the fact that emissions of ozone precursors (nitrogen oxides (NOx) and volatile organic compounds (VOC)) are like those of other regions of the USA affected by acute ozone problems. The population density, industry, and use of automobiles are other factors contributing to the difficulty of maintaining acceptable ozone levels. The ozone problem is especially severe in the New York metropolitan area and most of New Jersey. Strategies for combating ozone precursors have relied entirely on reducing emissions of VOCs, while little has been done to reduce NOx, except for automobile emissions. The Clean Air Act of 1990 provides for significant reductions of NOx and VOC from mobile sources and insists on VOC emissions reductions from stationary sources. In California, stricter emission standards for VOC and NOx have been implemented for new vehicles, requiring wider use of low- or zero-emission vehicles. The Northeast States for Coordinated Air Use Management (NESCAUM) organization, formed by the state agencies responsible for air quality, is aiding the northeast states to evaluate the advantages of adopting California standards for vehicles. Twelve northeast states propose to adopt the Californian low-emission vehicle program and are examining other options such as reformulated gasolines, improved maintenance and verification programs, and measures to reduce the number of miles travelled. 1 fig., 1 tab

    Full text: Radon is a naturally occurring gas seeping into homes and underground structures (buildings, tunnels, hangars, garages, etc.) from the surrounding soil through walls, floor, etc. and emanating from construction materials such as concrete, granite, etc. The level of radon is especially great in regions with the heightened content of uranium in soil and water and with geological breaks of the earth's crust. Concentrations of uranium higher than 10 g per ton of soil have been found in 14 percent of territory of Uzbekistan. As a result, for instance, concentration of radon 10-100 times exceeds the regulation level in 14 percent of premises in Tashkent, 41 percent of premises in Almalik town and 44 percent in Yangiabad town. The purpose of this work was creating a method to reduce concentration of radon gas in buildings and underground structures. We suppose that the most effective technique is a treatment of walls, floors, etc. of basement and underground structures by special chemicals which seal micropores inside the construction materials. Sealing the pores stops radon diffusion and in addition, it blocks another radon pathway - water migration and emanation from concrete, gypsum or other construction materials. In the paper polymeric silico organic compounds are investigated and selected as the chemicals to prevent radon seeping indoors. Gas (air, Ar, Rn 222, H 2 O) permeability of concrete and gypsum after treatment by chemicals has been examined. Influence of types of cement and sand, preliminary treatment by different chemicals, different types of polymeric silico organic compounds, time between treatments, moisture of concrete, time between preparation of chemicals and treatment of concrete (aging of chemicals), time between treatment of concrete and testing (aging of treated concrete) have been examined. Surfaces of the samples were treated by spray. Experiments have shown that chosen method of treatment of the construction materials allows reducing

  4. Population characteristics may reduce the levels of individual call identity.

    Directory of Open Access Journals (Sweden)

    María del Mar Delgado

    Full Text Available Individual variability influences the demographic and evolutionary dynamics of spatially structured populations, and conversely ecological and evolutionary dynamics provide the context under which variations at the individual level occur. Therefore, it is essential to identify and characterize the importance of the different factors that may promote or hinder individual variability. Animal signaling is a prime example of a type of behavior that is largely dependent on both the features of individuals and the characteristics of the population to which they belong. After 10 years studying the dynamics of a population of a long-lived species, the eagle owl (Bubo bubo, we investigated the emergence and maintenance of traits that reveal individual identity by focusing on vocal features. We found that individuals inhabiting a high density population characterized by a relative lack of heterogeneity (in terms of prey availability and breeding success among breeding sites might be selected for reducing the levels of identity. Two non-mutually exclusive hypotheses may explain the structural call patterns we detected: (1 similarity in calls may be principally a consequence of the particular characteristics of the population; and (2 high density may encourage individuals to mimic each other's vocalizations in a cascade effect, leading to a widespread and unique communication network.

    The aim of this work was to study the ultrasound-assisted water extraction of sugar from sugar beet cossettes. The ultrasound bath device (25 kHz, 200 W) was used. The sonication accelerated sugar diffusion at both temperatures 18 deg C and 77.6 deg C and gave the higher level of dry matter content SS (4-6 percent) and sugar content CK (7-22 percent) in juice. The SS and CK depended on time of exposition, time and temperature of extraction. In particular, the effects of 5 min ultrasound-assisted extraction were equal to 20 min extraction in traditional conditions. The shorter time, lower temperature, higher efficiency and purity of juice could be the effects of sugar extraction with ultrasound. The change of thickness of diffusion membrane, microflows in tissue as well as it's environment caused by ultrasound was the reason of acceleration of sugar extraction

    Interventions targeting portion size and energy density of food and beverage products have been identified as a promising approach for obesity prevention. This study modelled the potential cost-effectiveness of: a package size cap on single-serve sugar sweetened beverages (SSBs) >375 mL (package size cap), and product reformulation to reduce energy content of packaged SSBs (energy reduction). The cost-effectiveness of each intervention was modelled for the 2010 Australia population using a multi-state life table Markov model with a lifetime time horizon. Long-term health outcomes were modelled from calculated changes in body mass index to their impact on Health-Adjusted Life Years (HALYs). Intervention costs were estimated from a limited societal perspective. Cost and health outcomes were discounted at 3%. Total intervention costs estimated in AUD 2010 were AUD 210 million. Both interventions resulted in reduced mean body weight (package size cap: 0.12 kg; energy reduction: 0.23 kg); and HALYs gained (package size cap: 73,883; energy reduction: 144,621). Cost offsets were estimated at AUD 750.8 million (package size cap) and AUD 1.4 billion (energy reduction). Cost-effectiveness analyses showed that both interventions were “dominant”, and likely to result in long term cost savings and health benefits. A package size cap and kJ reduction of SSBs are likely to offer excellent “value for money” as obesity prevention measures in Australia. PMID:28878175

    Full Text Available In order to produce bioethanol from yellow poplar sawdust without detoxification, deacetylation (mild alkali treatment was performed with aqueous ammonia solution. To select the optimal conditions, deacetylation was carried out under different conditions: NH4OH loading (2–10% (w/v and a solid-to-liquid ratio of 1:4–1:10 at 121 °C for 60 min. In order to assess the effectiveness of deacetylation, fractionation of deacetylated yellow poplar sawdust was performed using dilute acid (H2SO4, 0.5–2.0% (w/v at a reaction temperature of 130–150 °C for 10–80 min. The toxicity-reduced hemicellulosic hydrolyzates that were obtained through a two-step treatment at optimized conditions were fermented using Pichia stipitis for ethanol production, without any further detoxification. The maximum ethanol production was 4.84 g/L, corresponding to a theoretical ethanol yield of 82.52%, which is comparable to those of intentionally made hydrolyzates as controls.

    Atmospheric carbon dioxide (CO(2)) concentration is an environmental factor currently undergoing dramatic changes. The objective of the present study was to determine the effect of doubling the ambient CO(2) concentration on plant photochemistry as measured by photochemical quenching coefficient (qP), soluble sugars and volatiles in broccoli. Elevated CO(2) concentration increased qP values in leaves by up to 100% and 89% in heads, while glucose and sucrose in leaves increased by about 60%. Furthermore, in broccoli heads elevated CO(2) concentration induced approximately a 2-fold increase in concentrations of three fatty acid-derived C(7) aldehydes ((E)-2-heptenal, (E,Z)-2,4-heptadienal, (E,E)-2,4-heptadienal), two fatty acid-derived C(5) alcohols (1-penten-3-ol, (Z)-2-pentenol), and two amino acid-derived nitriles (phenyl propanenitrile, 3-methyl butanenitrile). In contrast, concentrations of the sulfur-containing compound 2-ethylthiophene and C(6) alcohol (E)-2-hexenol decreased. Finally, elevated CO(2) concentration increased soluble sugar concentrations due to enhanced photochemical activity in leaves and heads, which may account for the increased synthesis of volatiles.

    Cluster headache (CH) is a debilitating disorder characterized by unilateral, severe pain attacks with accompanying autonomic symptoms, often waking the patient from sleep. As it exhibits strong chronobiological traits and genetic studies have suggested a link with the hypocretin (HCRT) system, the objective of this study was to investigate HCRT-1 in CH patients. Cerebrospinal fluid HCRT-1 concentration was measured in 12 chronic and 14 episodic CH patients during an active bout, and in 27 healthy controls. The patients were well characterized and clinical features compared to the HCRT concentration. We found significantly lower HCRT levels both in chronic (p = 0.0221) and episodic CH (p = 0.0005) patients compared with controls. No significant relationship was found with other clinical features. This is the first report of significantly reduced HCRT concentrations in CH patients. We speculate that decreased HCRT may reflect insufficient antinociceptive activity of the hypothalamus. The mechanism of the antinociceptive effect of HCRT is not known and requires further investigation. This study supports the hypothesis of a connection between arousal regulation and CH. © International Headache Society 2014.

    Cytokinins are phytohormones that play multiple roles to control plant growth and development. In this study, leaf biomass and the production of andrographolide compounds in a medicinal plant Andrographis paniculata were significantly increased after exogenously treating with the synthetic cytokinin cytokinin-1-(2-chloro-4-pyridyl)-3-phenylurea (CPPU) at 0 (water), 5, or 10 mg L -1 and observed the results for 24 h, 48 h, and 7 days of treatment. It was found that CPPU could significantly enhance new axillary bud formation and further promote branching 4.6-5.6-fold higher, resulting in higher fresh weight (FW) and dry weight (DW) than the control. Application of CPPU at 5 mg L -1 significantly promoted the highest contents of total reducing sugar at 2.5-fold in leaves and at 1.5-fold in roots. Although treatments of CPPU significantly affected the increasing contents of chlorophyll and carotenoid (1.2-1.6-fold), CPPU at 10 mg L -1 slightly caused leaf stress and chlorophyll reduction. Interestingly, 5 mg L -1 CPPU could enhance andrographolide content, an active anti-infectious compound in Andrographis paniculata (2.2-fold higher than the control) that reached the highest content at 24 h after treatment. This study suggested that CPPU should be suitable for field application to promote leaf yields and induce the production of useful pharmaceutical compounds in Andrographis paniculata.

    In the current investigation, statistical approaches were adopted to hydrolyse non-edible seed cake (NESC) of Pongamia and optimize the hydrolysis process by response surface methodology (RSM). Through the RSM approach, the optimized conditions were found to be 1.17%v/v of HCl concentration at 54.12 min for hydrolysis. Under optimized conditions, the release of reducing sugars was found to be 53.03 g/L. The RSM data were used to train the artificial neural network (ANN) and the predictive ability of both models was compared by calculating various statistical parameters. A three-layered ANN model consisting of 2:12:1 topology was developed; the response of the ANN model indicates that it is precise when compared with the RSM model. The fit of the models was expressed with the regression coefficient R 2 , which was found to be 0.975 and 0.888, respectively, for the ANN and RSM models. This further demonstrated that the performance of ANN was better than that of RSM.

  14. Reducing ethylene levels along the food supply chain: a key to reducing food waste?

    Blanke, Michael M

    2014-09-01

    Excessive waste along the food supply chain of 71 (UK, Netherlands) to 82 (Germany) kg per head per year sparked widespread criticism of the agricultural food business and provides a great challenge and task for all its players and stakeholders. Origins of this food waste include private households, restaurants and canteens, as well as supermarkets, and indicate that 59-65% of this food waste can be avoided. Since ∼50% of the food waste is fruit and vegetables, monitoring and control of their natural ripening gas - ethylene - is suggested here as one possible key to reducing food waste. Ethylene accelerates ripening of climacteric fruits, and accumulation of ethylene in the supply chain can lead to fruit decay and waste. While ethylene was determined using a stationary gas chromatograph with gas cylinders, the new generation of portable sensor-based instruments now enables continuous in situ determination of ethylene along the food chain, a prerequisite to managing and maintaining the quality and ripeness of fruits and identifying hot spots of ethylene accumulation along the supply chain. Ethylene levels were measured in a first trial, along the supply chain of apple fruit from harvest to the consumer, and ranged from 10 ppb in the CA fruit store with an ethylene scrubber, 70 ppb in the fruit bin, to 500 ppb on the sorting belt in the grading facility, to ppm levels in perforated plastic bags of apples. This paper also takes into account exogenous ethylene originating from sources other than the fruit itself. Countermeasures are discussed, such as the potential of breeding for low-ethylene fruit, applications of ethylene inhibitors (e.g. 1-MCP) and absorber strips (e.g. 'It's Fresh', Ryan'), packages (e.g. 'Peakfresh'), both at the wholesale and retail level, vents and cooling for the supply chain, sale of class II produce ('Wunderlinge'), collection (rather than waste) of produce on the 'sell by' date ('Die Tafel') and whole crop purchase (WCP) to aid reducing

    Various sugar substitutes have been introduced and are widely used in confections and beverages to avoid tooth decay from sugar and other fermentable carbohydrates. One group of sugar substitutes are sugar alcohols or polyols. They have been specifically used in foods for diabetic patients because polyols are not readily absorbed in the intestine and blood stream, preventing post-prandial elevation of glucose level. Additionally they may lower caloric intake. We searched PubMed, Cochrane Controlled Trials Registry, Cochrane Oral Health Review, Centre for Reviews and Dissemination in the UK, National Library for Public Health and a Centre for Evidence Based Dentistry website up to the end of October 2010, using the search terms 'sugar alcohol' or 'sugar-free' or 'polyols' and combined with a search with terms 'dental caries' or 'dental erosion'. Xylitol, a polyol, has been approved by the US Food and Drug Administration for its non-cariogenic properties that actually reduce the risk of dental decay and recently, the European Union also officially approved a health claim about xylitol as a 'tooth friendly' component in chewing gums. Although the presence of acidic flavourings and preservatives in sugar-free products has received less attention, these additives may have adverse dental health effects, such as dental erosion. Furthermore, the term sugar-free may generate false security because people may automatically believe that sugar-free products are safe on teeth. We concluded that polyol-based sugar-free products may decrease dental caries incidence but they may bring another dental health risk, dental erosion, if they contain acidic flavouring. There is a need for properly conducted clinical studies in this area.

    Full Text Available Abstract Background Reducing sugar-sweetened beverage (SSB intake is an important dietary target among underserved children at high risk for obesity and associated morbidities. Community-based approaches to reduce SSB intake are needed. The use of narrative-based approaches (presenting messages within the context of a story can facilitate connection with target health messages and empower children as behavior change agents within their families. The H2GO! program is a community-based behavioral intervention that integrates narrative-based strategies to reduce SSB consumption and promote water intake among school-age youth and parents. Methods Guided by the Social Cognitive Theory and the Social Ecological Model, the H2GO! intervention consists of 6 weekly sessions that target beverage knowledge, attitudes, and behaviors through youth-produced messages and narratives to reduce SSB intake and encourage water intake and parent–child activities. To reach underserved youth and families, we identified Boys & Girls Clubs (B&GC (youth-based community centers that serve an ethnically diverse and predominantly low socioeconomic status population as a community partner and study setting. Participants (children ages 9–12 years and their parents will be recruited from B&GC sites in Massachusetts, USA. Intervention efficacy will be assessed through a site-randomized trial (N = 2 youth-based community sites, pair-matched for size and racial/ethnic composition with 54 parent–child pairs (N = 108 enrolled per site (N = 216 total. The comparison site will carry on with usual practice. Child and parental SSB and water consumption (primary outcomes and parent and child beverage knowledge and attitudes (secondary outcomes will be measured via self-report surveys. Additional outcomes include children’s anthropometric data, additional dietary behaviors, and physical activity. Measures will be collected at baseline, 2 and 6 months follow-up. With

    Full Text Available A high amount of sugar is used in bakery products, which may cause diabetes, high blood glucose levels and obesity. Due to these reasons, sugar is being replaced with substitutes. There is different carbohydrate-based sugar substitutes (polyols that can efficiently replace sugar. Among polyols, sorbitol is an efficient replacer that can mimic sugar with minimal effects on cookie quality. Effects of different sorbitol levels (0 to 12.5% were seen on the dough rheology. Mixographic studies showed that peak height and mixing time reduced with the addition of sorbitol. Farinographic studies showed that water absorption and the mixing tolerance index of dough reduced with the supplementation of sorbitol, whereas dough development time, arrival time, dough stability time and softening of dough increased. Extensographic studies revealed that sorbitol substitution produced hard, cohesive, adhesive and elastic dough. Sugar in cookies formulations was reduced from 100 to 50% by replacing with sorbitol 0 to 50%. Physical analysis of sorbitol containing cookies showed that the diameter and spread factor of cookies decreased with higher levels of sorbitol, whereas thickness, color, hardness and water activity of cookies increased. The calorific value of cookies decreased with the increasing levels of sorbitol. At upto 20% replacement of sugar, other parameters of cookies were not affected. Sensory evaluation of the cookies showed that hedonic points for sensory evaluation parameters reduced with the increasing levels of sorbitol, T2 (20% replacement showed maximum overall acceptability.

    Objectives To investigate the free sugars and calorie content of carbonated sugar-sweetened beverages (CSSB) available in the main UK supermarkets. Study design We carried out a cross-sectional survey in 2014 of 169 CSSB. Methods The free sugars (sugars g/100 mL) and calorie (kcal/100 mL) were collected from product packaging and nutrient information panels of CSSB available in 9 main UK supermarkets. Results The average free sugars content in CSSB was 30.1±10.7 g/330 mL, and 91% of CSSB would receive a ‘red’ (high) label for sugars per serving. There was a large variation in sugars content between different flavours of CSSB and within the same type of flavour ranging from 3.3 to 52.8 g/330 mL. On average, ginger beer (38.5±9.9 g/330 mL) contained the highest amounts of sugars and ginger ale (22.9±7.7 g/330 mL) contained the lowest. Cola flavour is the most popular flavour in the UK with an average free sugars content of 35.0±1.1 g/330 mL. On average, the supermarket own brand contained lower levels of sugars than branded products (27.9±10.6 vs 31.6±10.6 g/330 mL, p=0.02). The average calorie content in CSSB was 126.1±43.5 kcal/330 mL. Cola flavour had a calorie content of 143.5±5.2 kcal/330 mL. Among the 169 products surveyed, 55% exceeded the maximum daily recommendation for free sugars intake (30 g) per 330 mL. Conclusions Free sugars content of CSSB in the UK is high and is a major contributor to free sugars intake. There is a wide variation in the sugars content of CSSB and even within the same flavour of CSSB. These findings demonstrate that the amount of free sugars added to CSSB can be reduced without technical issues, and there is an urgent need to set incremental free sugars reduction targets. A reduction in sugars content and overall CSSB consumption will be very beneficial in reducing obesity, type 2 diabetes and dental caries. PMID:28186923

  3. Health benefits of reducing sugar-sweetened beverage intake in high risk populations of California: results from the cardiovascular disease (CVD policy model.

    Tekeshe A Mekonnen

    Full Text Available Consumption of sugar-sweetened beverage (SSB has risen over the past two decades, with over 10 million Californians drinking one or more SSB per day. High SSB intake is associated with risk of type 2 diabetes, obesity, hypertension, and coronary heart disease (CHD. Reduction of SSB intake and the potential impact on health outcomes in California and among racial, ethnic, and low-income sub-groups has not been quantified.We projected the impact of reduced SSB consumption on health outcomes among all Californians and California subpopulations from 2013 to 2022. We used the CVD Policy Model - CA, an established computer simulation of diabetes and heart disease adapted to California. We modeled a reduction in SSB intake by 10-20% as has been projected to result from proposed penny-per-ounce excise tax on SSB and modeled varying effects of this reduction on health parameters including body mass index, blood pressure, and diabetes risk. We projected avoided cases of diabetes and CHD, and associated health care cost savings in 2012 US dollars.Over the next decade, a 10-20% SSB consumption reduction is projected to result in a 1.8-3.4% decline in the new cases of diabetes and an additional drop of 0.5-1% in incident CHD cases and 0.5-0.9% in total myocardial infarctions. The greatest reductions are expected in African Americans, Mexican Americans, and those with limited income regardless of race and ethnicity. This reduction in SSB consumption is projected to yield $320-620 million in medical cost savings associated with diabetes cases averted and an additional savings of $14-27 million in diabetes-related CHD costs avoided.A reduction of SSB consumption could yield substantial population health benefits and cost savings for California. In particular, racial, ethnic, and low-income subgroups of California could reap the greatest health benefits.

    Sugar intake has been associated with an increased prevalence of obesity, other noncommunicable diseases, and dental caries. The WHO recommends that free sugars should be ENSANUT (National Health and Nutrition Survey) 2012], which represents 3 geographic regions and urban and rural areas. Dietary information was obtained by administering a 24-h recall questionnaire to 10,096 participants. Total sugar intake was estimated by using the National Institute of Public Health (INSP) food-composition table and an established method to estimate added sugars. The mean intakes of total, intrinsic, and added sugars were 365, 127, and 238 kcal/d, respectively. Added sugars contributed 13% of TEI. Sugar-sweetened beverages (SSBs) were the main source of sugars, contributing 69% of added sugars. Food products high in saturated fat and/or added sugar (HSFAS) were the second main sources of added sugars, contributing 25% of added sugars. The average intake of added sugars in the Mexican diet is higher than WHO recommendations, which may partly explain the high prevalence of obesity and diabetes in Mexico. Because SSBs and HSFAS contribute >94% of total added sugars, strategies to reduce their intake should be strengthened. This includes stronger food labels to warn the consumer about the content of added sugars in foods and beverages. © 2016 American Society for Nutrition.

    Full Text Available Abstract Background This study describes the continuation of a program to constrain health care costs by limiting inpatient hospital programs among the hospitals of Syracuse, New York. Through a community demonstration project, it identified components of individual hospital programs for reduction of complications and their impact on the frequency and rates of these outcomes. Findings This study involved the implementation of interventions by three hospitals using the Potentially Preventable Complications System developed by 3M™ Health Information Systems. The program is noteworthy because it included competing hospitals in the same community working together to reduce adverse patient outcomes and related costs. The study data identified statistically significant reductions in the frequency of high and low volume complications during the three year period at two of the hospitals. At both of these hospitals, aggregate complication rates also declined. At these hospitals, the differences between actual complication rates and severity adjusted complication rates were also reduced. At the third hospital, specific and aggregate complication rates remained the same or increased slightly. Differences between these rates and those of severity adjusted comparison population also remained the same or increased. Conclusions Results of the study suggested that, in one community health care system, the progress of reducing complications involved different experiences. At two hospitals with relatively higher rates at the beginning of the study, management by administrative and clinical staff outside quality assurance produced significant reductions in complication rates, while at a hospital with lower rates, management by quality assurance staff had little effect on reducing the rate of PPCs.

    2017-11-01

    Non-glucose sugars derived from lignocellulose cover approximately 40% of the total carbohydrates of lignocellulose biomass. The conversion of the non-glucose sugars to the target products is an important task of lignocellulose biorefining research. Here we report a fast and complete conversion of the total non-glucose sugars from corn stover into the corresponding sugar acids by whole cell catalysis and aerobic fermentation of Gluconobacter oxydans. The conversions include xylose to xylonate, arabinose to arabonate, mannose to mannonate, and galactose to galactonate, as well as with glucose into gluconate. These cellulosic non-glucose sugar acids showed the excellent cement retard setting property. The mixed cellulosic sugar acids could be used as cement retard additives without separation. The conversion of the non-glucose sugars not only makes full use of lignocellulose derived sugars, but also effectively reduces the wastewater treatment burden by removal of residual sugars.

    We used functional MRI and the anesthetic agent propofol to assess the relationship among neural responses to speech, successful comprehension, and conscious awareness. Volunteers were scanned while listening to sentences containing ambiguous words, matched sentences without ambiguous words, and signal-correlated noise (SCN). During three scanning sessions, participants were nonsedated (awake), lightly sedated (a slowed response to conversation), and deeply sedated (no conversational response, rousable by loud command). Bilateral temporal-lobe responses for sentences compared with signal-correlated noise were observed at all three levels of sedation, although prefrontal and premotor responses to speech were absent at the deepest level of sedation. Additional inferior frontal and posterior temporal responses to ambiguous sentences provide a neural correlate of semantic processes critical for comprehending sentences containing ambiguous words. However, this additional response was absent during light sedation, suggesting a marked impairment of sentence comprehension. A significant decline in postscan recognition memory for sentences also suggests that sedation impaired encoding of sentences into memory, with left inferior frontal and temporal lobe responses during light sedation predicting subsequent recognition memory. These findings suggest a graded degradation of cognitive function in response to sedation such that “higher-level” semantic and mnemonic processes can be impaired at relatively low levels of sedation, whereas perceptual processing of speech remains resilient even during deep sedation. These results have important implications for understanding the relationship between speech comprehension and awareness in the healthy brain in patients receiving sedation and in patients with disorders of consciousness.

    Enzyme-functionalized dual-peak long-period fiber grating (LPFG) inscribed in 80-μm-cladding B/Ge codoped single-mode fiber is presented for sugar-level and specific glucose detection. Before enzyme functionalization, the dual-peak LPFG was employed for refractive index sensing and sugar-level detection and high sensitivities of ˜4298.20 nm/RIU and 4.6696 nm/% were obtained, respectively. Glucose detection probe was attained by surface functionalization of the dual-peak LPFG via covalent binding with aminopropyl triethoxysilane used as a binding site. Optical micrographs confirmed the presence of enzyme. The surface-functionalized dual-peak LPFG was tested with D-(+)-glucose solution of different concentrations. While the peak 2 at the longer wavelength was suitable only to measure lower glucose concentration (0.1 to 1.6 mg/ml) recording a high sensitivity of 12.21±0.19 nm/(mg/ml), the peak 1 at the shorter wavelength was able to measure a wider range of glucose concentrations (0.1 to 3.2 mg/ml) exhibiting a maximum resonance wavelength shift of 7.12±0.12 nm/mg/ml. The enzyme-functionalized dual-peak LPFG has the advantage of direct inscription of highly sensitive grating structures in thin-cladding fibre without etching, and most significantly, its sensitivity improvement of approximately one order of magnitude higher than previously reported LPFG and excessively tilted fibre grating (Ex-TFG) for glucose detection.

    Sweet sorghum juice (Sorghum bicolor L. Moench) has characteristics similar to sugar cane juice and potentially used for sugar substitutes that can support food security. Nevertheless the sweet sorghum juicecontain starch which impede sorghum sugar crystallization. Therefore, research on the enzymatic process is needed to convert starch into reducing sugar. The experimental design used was the Factorial Randomized Design with the first factor was alpha amylase enzyme concentration (0, 20, 40, 60, 80, 100, 120 μL/100 mL) and second factor was incubation time (0, 30, 60, 90 minute) at temperature 100°C. The experiment was conducted on fresh sweet sorghum. The results showed that the addition of the alpha amylase enzyme increased the content of reducing sugar and decreased levels of starch. Elevating concentration of alpha amylase enzyme will increase the reducing sugar content in sweet sorghum juice. The optimum alpha amylase enzyme concentration to produce the highest total sugar was 80 μL/100 mL of sweet sorghum juice with the optimum incubation time was 90 minutes. The results of this study are expected to create a new sweetener for sugar substitution. From the economic prospective aspect, sorghum is a potential crop and can be relied upon to support the success of the food diversification program which further leads to the world food security

    To evaluate the relationship between insulin resistance-associated metabolic parameters and anthropometric measurements with sugar-sweetened beverage intake and physical activity levels. A cross-sectional analysis of the National Health and Nutrition Examination Survey data collected by the National Center for Health Statistics. Nationally representative samples of US adolescents participating in the National Health and Nutrition Examination Survey during the years 1999-2004. A total of 6967 adolescents aged 12 to 19 years. Sugar-sweetened beverage consumption and physical activity levels. Glucose and insulin concentrations, a homeostasis model assessment of insulin resistance (HOMA-IR), total, high-density lipoprotein, and low-density lipoprotein cholesterol concentrations, triglyceride concentrations, systolic and diastolic blood pressure, waist circumference, and body mass index (calculated as weight in kilograms divided by height in meters squared) percentile for age and sex. Multivariate linear regression analyses showed that increased sugar-sweetened beverage intake was independently associated with increased HOMA-IR, systolic blood pressure, waist circumference, and body mass index percentile for age and sex and decreased HDL cholesterol concentrations; alternatively, increased physical activity levels were independently associated with decreased HOMA-IR, low-density lipoprotein cholesterol concentrations, and triglyceride concentrations and increased high-density lipoprotein cholesterol concentrations. Furthermore, low sugar-sweetened beverage intake and high physical activity levels appear to modify each others' effects of decreasing HOMA-IR and triglyceride concentrations and increasing high-density lipoprotein cholesterol concentrations.

    Public health organizations in the United States have recently increased focus on reducing population consumption of added sugars. The objective of this study is to provide in-depth information on national trends in added sugars consumption and to examine both the mean and distribution of added sugars intake from 1977 to 2012. We conducted a descriptive study using six cross-sectional nationally representative surveys of food intake in the United States: the 1977-1978 National Food Consumption Survey (n=29,668), the 1989-1991 Continuing Survey of Food Intake by Individuals (n=14,827), the 1994-1998 Continuing Survey of Food Intake by Individuals (n=19,027), the 2003-2004 National Health and Nutrition Examination Survey (NHANES; n=8,273), the 2009-2010 NHANES (n=9,042), and the 2011-2012 NHANES (n=16,451). We examined the key dependent variables, calories from added sugars and percentage of total energy intake from added sugars, at the mean and by quintiles of added sugars consumption for children (2 to 18 years) and adults (19 years and older) across the survey years. We also examined trends in added sugars intakes from foods and beverages. We used ordinary least squares regression to examine linear trends between survey years and multinomial logistic regressions to examine sociodemographic characteristics by quintile of added sugars consumption. We adjusted estimates by race, income, sex, and education. The US mean adjusted intake of added sugars remains high. In 2011-2012, children and adults consumed 326 kcal/day and 308 kcal/day, respectively, of added sugars, or 14% and 17%, respectively, of total their energy. For both children and adults, there was a considerable increase in calories from added sugars from 1977 to 2003, followed by a substantial decline from 2003 to 2012. There was no decline in the percentage of total energy intake from added sugars from 2003 to 2012. Changes over time were consistent across each quintile of added sugars consumption. The

Objective The objective of this study is to provide in-depth information on national trends in added sugars consumption and examine both the mean and the distribution of added sugars intake from 1977 to 2012. Design We conducted a descriptive study using 6 cross-sectional nationally representative surveys of food intake in the United States: the 1977–1978 National Food Consumption Survey (NFCS; n = 29,668), the 1989–1991 Continuing Survey of Food Intake by Individuals (CSFII; n = 14,827), the 1994–1998 CSFII (n = 19,027), the 2003–2004 National Health and Nutrition Examination Survey (NHANES; n = 8,273), the 2009–2010 NHANES (n = 9,042), and the 2011–2012 NHANES (n = 16,451). Analysis We examined the key dependent variables calories from added sugars and percentage of total energy intake from added sugars at the mean and by quintiles of added sugars consumption for children (2–18 years) and adults (≥ 19 years) across the survey years. We also examined trends in added sugars intakes from foods and beverages. We used ordinary least squares regression to examine linear trends between survey years and multinomial logistic regressions to examine sociodemographics by quintile of added sugars consumption.

    The aim of this study is to investigate and understand the dynamic changes and the possible functions of hormones, water and sugar content during the development of C. oleifera. We analyzed and compared WWC, WSS and five endogenous hormones (DHZR, ZR, GA, IAA and ABA) contents between May and August in C. oleifera plants at different ages from the same orchard. The results showed that WWC, WSS, DHZR, ZR, GA, IAA and ABA contents varied from 61.64%-74.15%, 21.24mg/g-62.44mg/g, 6.237ng/g-38.342ng/g, 6.215ng/g-16.721ng/g, 5.668ng/g-18.024ng/g, 24.753ng/g-147.507ng/g and 66.541ng/g-156.212ng/g, respectively. WWC showed a decrease-increase-decrease variation pattern, while the WSS contents demonstrated a generally increasing trend with increasing tree age. The levels of ABA in leaves sampled in August was higher than that in May, but the opposite was found for the GA and IAA levels. Tree ages were negatively correlated with ZR and GA concentration at the 1% or 5% significance level. The results of this study broaden our understanding of the interrelationships between phytohormones, WWC, and WSS content in the growth and development of C. oleifera. (author)

    Full Text Available Strip-till save costs by reducing tillage on the area of sugar beet rows only. The seeding system is characterized by a deep loosening of soil with a tine combined with a share and by following tools generating fine-grained soil as seed bed. In cooperation with the Kverneland company group Soest/Germany a strip tiller combined with precision seeder was designed and tested in field experiments. Tilling and seeding was performed in one path on fields with straw and mustard mulch. Even the plant development was slower as compared to conventional sawn sugar beets the yield was on equivalent level. Further field experiments are planned to attest constant yield, cost and energy efficiency of the seeding system.

  4. Starches, Sugars and Obesity

    Full Text Available The rising prevalence of obesity, not only in adults but also in children and adolescents, is one of the most important public health problems in developed and developing countries. As one possible way to tackle obesity, a great interest has been stimulated in understanding the relationship between different types of dietary carbohydrate and appetite regulation, body weight and body composition. The present article reviews the conclusions from recent reviews and meta-analyses on the effects of different starches and sugars on body weight management and metabolic disturbances, and provides an update of the most recent studies on this topic. From the literature reviewed in this paper, potential beneficial effects of intake of starchy foods, especially those containing slowly-digestible and resistant starches, and potential detrimental effects of high intakes of fructose become apparent. This supports the intake of whole grains, legumes and vegetables, which contain more appropriate sources of carbohydrates associated with reduced risk of cardiovascular and other chronic diseases, rather than foods rich in sugars, especially in the form of sugar-sweetened beverages.

  5. Sugar Price Supports and Taxation

    2017-01-01

    Domestic US sugar production has been protected by government policy for the past 82 years, resulting in elevated domestic prices and an estimated annual (2013) $1.4 billion dollar “tax” on consumers. These elevated prices and the simultaneous federal support for domestic corn production have ensured a strong market for high-fructose corn syrup. Americans have dramatically increased their consumption of caloric sweeteners during the same period. Consumption of “empty” calories (ie, foods with low-nutrient/high-caloric density)—sugar and high-fructose corn syrup being the primary sources—is considered by most public health experts to be a key contributing factor to the rise in obesity. There have been substantial efforts to tax sugar-sweetened beverages (SSBs) to both reduce consumption and provide a source of funds for nutrition education, thereby emulating the tobacco tax model. Volume-based SSB taxes levy the tax rate per ounce of liquid, where some are only imposed on beverages with added sugar content exceeding a set threshold. Nonetheless, volume-based taxes have significant limitations in encouraging consumers to reduce their caloric intake due to a lack of transparency at the point of purchase. Thus, it is hypothesized that point-of-purchase, nutrient-specific excise taxes on SSBs would be more effective at reducing sugar consumption. However, all SSB taxes are limited by the possibility that consumers may compensate their decreased intake from SSBs with other high-calorie junk foods. Furthermore, there are no existing studies to provide evidence on how SSB taxes will impact obesity rates in the long term. The paradox of sugar prices is that Americans have paid higher prices for sugar to protect domestic production for more than 80 years, and now, Americans are being asked to pay even more to promote public health. The effective use of sugar taxes should be considered based on their merits in reducing sugar consumption and making available a new

    Sugars are important nutrients for many animals, but are also proposed to contribute to overnutrition-derived metabolic diseases in humans. Understanding the genetic factors governing dietary sugar tolerance therefore has profound biological and medical significance. Paralogous Mondo transcription factors ChREBP and MondoA, with their common binding partner Mlx, are key sensors of intracellular glucose flux in mammals. Here we report analysis of the in vivo function of Drosophila melanogaster Mlx and its binding partner Mondo (ChREBP) in respect to tolerance to dietary sugars. Larvae lacking mlx or having reduced mondo expression show strikingly reduced survival on a diet with moderate or high levels of sucrose, glucose, and fructose. mlx null mutants display widespread changes in lipid and phospholipid profiles, signs of amino acid catabolism, as well as strongly elevated circulating glucose levels. Systematic loss-of-function analysis of Mlx target genes reveals that circulating glucose levels and dietary sugar tolerance can be genetically uncoupled: Krüppel-like transcription factor Cabut and carbonyl detoxifying enzyme Aldehyde dehydrogenase type III are essential for dietary sugar tolerance, but display no influence on circulating glucose levels. On the other hand, Phosphofructokinase 2, a regulator of the glycolysis pathway, is needed for both dietary sugar tolerance and maintenance of circulating glucose homeostasis. Furthermore, we show evidence that fatty acid synthesis, which is a highly conserved Mondo-Mlx-regulated process, does not promote dietary sugar tolerance. In contrast, survival of larvae with reduced fatty acid synthase expression is sugar-dependent. Our data demonstrate that the transcriptional network regulated by Mondo-Mlx is a critical determinant of the healthful dietary spectrum allowing Drosophila to exploit sugar-rich nutrient sources.

    Key recommendations in the 2010 Dietary Guidelines for Americans and US Department of Agriculture's MyPlate are to reduce the intake of added sugars, particularly from sugar-sweetened beverages, and drink water instead of "sugary" beverages. However, little is known about consumer knowledge, perceptions, and behaviors regarding sugars in beverages. We hypothesized that consumers would have limited or inaccurate knowledge of the sugars in beverages and that their beverage consumption behaviors would not reflect their primary concerns related to sugars in beverages. An online survey was completed by 3361 adults 18 years and older residing throughout the United States. Water was consumed in the highest amounts followed by (in descending amounts) other beverages (includes coffee and tea), added sugar beverages, milk, diet drinks, and 100% fruit juice and blends. Participants primarily associated the term "sugary" with beverages containing added sugars; however, almost 40% identified 100% fruit juice as sugary. Some participants misidentified the types of sugars in beverages, particularly with respect to milk and 100% fruit juices. Generally, beverage choices were consistent with stated concerns about total, added, or natural sugars; however, less than 40% of participants identified added sugars as a primary concern when choosing beverages despite public health recommendations to reduce the intake of added sugars and sugar-sweetened beverages. Results suggest that there may be a considerable level of consumer misunderstanding or confusion about the types of sugars in beverages. More consumer research and education are needed with the goal of helping consumers make more informed and healthy beverage choices. Copyright © 2014 Elsevier Inc. All rights reserved.

    To analyze the added sugars in kids' meals from Canadian chain restaurants in relation to the World Health Organization's proposed sugar recommendation (less than 5% of total daily calories should come from added sugars) and current recommendation (less than 10% of total daily calories should come from added sugars). Total sugar levels were retrieved from the websites of 10 fast-food and 7 sit-down restaurants in 2010. The added sugar levels in 3178 kids' meals from Canadian chain restaurants were calculated in 2014 (in Toronto, Canada) by subtracting all naturally occurring sugars from the total sugar level. The average amount of added sugars in restaurant kids' meals (25 ± 0.36 g) exceeded the WHO's proposed daily recommendation for sugar intake. There was a wide range of added sugar levels in kids' meals ranging from 0 g to 114 g. 50% of meals exceeded the WHO's proposed daily sugar recommendation, and 19% exceeded the WHO's current daily sugar recommendation. There is a wide range of sugar levels in kids' meals from restaurants, and many contain more than a day's worth of sugar.

    Recently, one of the rare sugars, D-allose, has received attention from many researchers because of its availability for mass production and its various physiological functions. Among these, an antioxidative effect has been strongly suggested. In this study, we investigated whether this effect is also applicable to the field of skin surgery. In ischemia-reperfusion injury model using the rat abdominal skin island flap (male Wistar rats, n = 110), D-allose was injected intravenously 15 min before 8-h ischemia. The survival area (%) was measured by digital photographic assessment 1 wk after surgery, and multiple comparisons (Fisher's protected least significant difference) were carried out. Histopathological examination (neutrophilic infiltration into dermis in hematoxylin and eosin stain) and immunostaining (of ectodermal dysplasia-1 (ED1)-positive cells/flap) were assessed. Myeloperoxidase (MPO) activity in the skin flap (sampling at the time of 8 h after reperfusion) was measured spectrophotometrically, and Student t-test was performed. D-allose extended the survival of the remaining flaps, and a dose greater than 30 mg (0.1 mg/g) was necessary to be effective. The flap survival rates in the 30, 60, and 150 mg groups were significantly higher than that in the control (saline) group: 75.87 ± 5.90, 79.27 ± 7.81, and 77.87 ± 6.20 versus 50.53 ± 9.66, respectively (P rare sugars are safer for our bodies as well as the environment; therefore, this rare sugar project is expected to lead to the development of a safer antioxidant for skin flap surgery.

    2013-09-01

    To investigate what level of sugar reduction is accepted in flavored yogurt, we conducted a hedonic test focusing on the degree of liking of the products and on optimal sweetness and aroma levels. For both flavorings (strawberry and coffee), consumers preferred yogurt containing 10% added sugar. However, yogurt containing 7% added sugar was also acceptable. On the just-about-right scale, yogurt containing 10% sugar was more often described as too sweet compared with yogurt containing 7% sugar. On the other hand, the sweetness and aroma intensity for yogurt containing 5% sugar was judged as too low. A second test was conducted to determine the effect of flavoring concentration on the acceptance of yogurt containing 7% sugar. Yogurts containing the highest concentrations of flavoring (11% strawberry, 0.75% coffee) were less appreciated. Additionally, the largest percentage of consumers perceived these yogurts as "not sweet enough." These results indicate that consumers would accept flavored yogurts with 7% added sugar instead of 10%, but 5% sugar would be too low. Additionally, an increase in flavor concentration is undesirable for yogurt containing 7% added sugar. Copyright © 2013 American Dairy Science Association. Published by Elsevier Inc.

  13. Operant licking for intragastric sugar infusions: differential reinforcing actions of glucose, sucrose and fructose in mice

    Science.gov (United States)

    Sclafani, Anthony; Ackroff, Karen

    2015-01-01

    Intragastric (IG) flavor conditioning studies in rodents indicate that isocaloric sugar infusions differ in their reinforcing actions, with glucose and sucrose more potent than fructose. Here we determined if the sugars also differ in their ability to maintain operant self-administration by licking an empty spout for IG infusions. Food-restricted C57BL/6J mice were trained 1 h/day to lick a food-baited spout, which triggered IG infusions of 16% sucrose. In testing, the mice licked an empty spout, which triggered IG infusions of different sugars. Mice shifted from sucrose to 16% glucose increased dry licking, whereas mice shifted to 16% fructose rapidly reduced licking to low levels. Other mice shifted from sucrose to IG water reduced licking more slowly but reached the same low levels. Thus IG fructose, like water, is not reinforcing to hungry mice. The more rapid decline in licking induced by fructose may be due to the sugar's satiating effects. Further tests revealed that the Glucose mice increased their dry licking when shifted from 16% to 8% glucose, and reduced their dry licking when shifted to 32% glucose. This may reflect caloric regulation and/or differences in satiation. The Glucose mice did not maintain caloric intake when tested with different sugars. They self-infused less sugar when shifted from 16% glucose to 16% sucrose, and even more so when shifted to 16% fructose. Reduced sucrose self-administration may occur because the fructose component of the disaccharide reduces its reinforcing potency. FVB mice also reduced operant licking when tested with 16% fructose, yet learned to prefer a flavor paired with IG fructose. These data indicate that sugars differ substantially in their ability to support IG self-administration and flavor preference learning. The same post-oral reinforcement process appears to mediate operant licking and flavor learning, although flavor learning provides a more sensitive measure of sugar reinforcement. PMID:26485294

    Background: Gestational diabetes mellitus (GDM) is emerging as an important public health problem in India owing to its increasing prevalence since the last decade. The issue addressed in the study was whether the management of blood sugar levels in GDM cases can predict maternal and fetal outcomes. Materials and Methods: A prospective cohort study was done for 1 year from October 1, 2013, to September 31, 2014, at 652 diabetic screening units as a part of the Gestational Diabetes Prevention and Control Project approved by the Indian Government in the district of Kanpur, state of Uttar Pradesh. A total of 57,108 pregnant women were screened during their 24–28th weeks of pregnancy by impaired oral glucose test. All types of maternal and perinatal outcomes were followed up in both GDM and non-GDM categories in the 2nd year (2013–2014) after blood sugar levels were controlled. Results: It was seen that for all kinds of maternal and fetal outcomes, the differences between GDM cases and non-GDM cases were highly significant (P 1 in every case). Moreover, perinatal mortality also increased significantly from 5.7% to 8.9% when blood sugar levels increased from 199 mg/dl and above. Perinatal and maternal outcomes in GDM cases were also significantly related to the control of blood sugar levels (P < 0.0001). Conclusion: Blood sugar levels can be an indicator of maternal and perinatal morbidity and mortality in GDM cases, provided unified diagnostic criteria are used by Indian laboratories. However, to get an accurate picture on this issue, all factors need further study. PMID:27186155

    Full Text Available Background: Sugar-sweetened beverage (SSB consumption is associated with the increasing prevalence of overweight and obesity in the United States; however, little is known about how less-healthy eating behaviors influence high levels of SSB consumption among rural adults. Objective: We assessed the frequency of SSB consumption among rural and urban adults, examined the correlates of frequent SSB consumption, and determined difference in correlates between rural and urban adults in a large region of Texas. Design: A cross-sectional study using data on 1,878 adult participants (urban = 734 and rural = 1,144, who were recruited by random digit dialing to participate in the seven-county 2006 Brazos Valley Community Health Assessment. Data included demographic characteristics, eating behaviors (SSB consumption, frequency of fast-food meals, frequency of breakfast meals, and daily fruit and vegetable intake, and household food insecurity. Results: The prevalence of any consumption of SSB and the prevalence of high consumption of SSB were significantly higher among rural adults compared with urban counterparts. The multivariable logistic regression models indicated that a high level of SSB consumption (≥3 cans or glasses SSB/day was associated with demographic characteristics (poverty-level income and children in the home, frequent consumption of fast-food meals, infrequent breakfast meals, low fruit and vegetable intake, and household food insecurity especially among rural adults. Conclusions: This study provides impetus for understanding associations among multiple eating behaviors, especially among economically and geographically disadvantaged adults. New strategies are needed for educating consumers, not only about how to moderate their SSB intake, but also how to simultaneously disrupt the co-occurrence of undesirable eating and promote healthful eating.

  18. Sugar beet for bioethanol production: An approach based on environmental agricultural outputs

    2013-01-01

    The EU imports both bioethanol and the raw material needed to produce it. Thirty percent of bioethanol is produced from sugar beets in the EU. However, sugar beet cultivated area and yields have fallen due to the 2006 sugar regime reform. Given the potential uncertainty about the future for sugar beet farmers, biofuels may represent an alternative market. This paper analyses potential contribution to the efficiency, in terms of environmental output, of the sugar beet crop both when production is oriented toward bioethanol and regarding the use of input. An empirical application is performed in Spain by Data Envelopment Analysis (DEA). The results show that 4% of farms have full technical efficiency, while the rest have an average efficiency of 55.9%. The figures show that inputs can be reduced over 40%, and also show the low average level of input-use efficiency. In addition, it cannot be said that there is a relationship between efficiency and farm scale. The consideration of aspects such as the environmental advantages of using sugar beet production for bioethanol can open new lines of action to support this crop in the EU. In addition, boosting sugar beet production may reduce potential dependency on importation. - Highlights: ► Analysing environmental outputs from agricultural input use and production orientation to bioethanol. ► DEA is applied to model farms’ efficiency in GHG emission and nitrous oxides emissions. ► A very low level of efficiency is found in sugar beet farms. ► Efficiency increase should be supported to reduce fertilizers and pesticides. ► Environmental advantages of addressing sugar beet to bioethanol open new lines to support crops

    Sugars are used by the industry to enhance the attractiveness of foods and drinks. These added sugars, or 'free sugars', are not easily identified in food or drink labels. Certain manufactured foods and drinks with 'safe' names, such as dried fruit and fruit juice, still contain free sugars and can be confusing. Guidance states that daily consumption of free sugars should be less than 10% of total energy intake (no more than 5% in the UK). However, it is found that both tooth decay and obesity are associated with consumption of free sugars in large quantities and at inappropriate times.

    Limited evidence has been gathered on the real-world impact of sugar-sweetened beverage price changes on purchasing behavior over time or in community-retail settings. Our aim was to determine changes in beverage purchases, business outcomes, and customer and retailer satisfaction associated with a retailer-led sugar-sweetened beverage price increase in a convenience store. We hypothesized that purchases of less-healthy beverages would decrease compared to predicted sales. A convergent parallel mixed methods design complemented sales data (122 weeks pre-intervention, 17 weeks during intervention) with stakeholder interviews and customer surveys. Electronic beverage sales data were collected from a convenience store in Melbourne, Australia (August through November 2015). Convenience store staff completed semi-structured interviews (n=4) and adult customers exiting the store completed surveys (n=352). Beverages were classified using a state government framework. Prices of "red" beverages (eg, nondiet soft drinks, energy drinks) increased by 20%. Prices of "amber" (eg, diet soft drinks, small pure fruit juices) and "green" beverages (eg, water) were unchanged. Changes in beverage volume, item sales, and revenue during the intervention were compared with predicted sales. Sales data were analyzed using time series segmented regression while controlling for pre-intervention trends, autocorrelation in sales data, and seasonal fluctuations. Beverage volume sales of red (-27.6%; 95% CI -32.2 to -23.0) and amber (-26.7%; 95% CI -39.3 to -16.0) decreased, and volume of green beverages increased (+26.9%; 95% CI +14.1 to +39.7) in the 17th intervention week compared with predicted sales. Store manager and staff considered the intervention business-neutral, despite a small reduction in beverage revenue. Fifteen percent of customers noticed the price difference and 61% supported the intervention. A 20% sugar-sweetened beverage price increase was associated with a reduction

    A number of intravenous immunoglobulin preparations are stabilized with sugar additives that may lead over time to undesirable glycation reactions especially in liquid formulation. This study aimed to evaluate the reactivity of sugar excipients on such preparations in condition of temperature, formulation and concentration commonly used for pharmaceutical products. Through an innovative LC-MS method reported to characterize post-translational modifications of IgGs Fc/2 fragments, a stability study of IVIg formulated with reducing and non-reducing sugars has been undertaken. The rate of polyclonal IgGs glycation was investigated during 6months at 5, 25, 30 and 40°C. High levels of glycation were observed with reducing sugars such as glucose and maltose in the first months of the stability study from 25°C. Non-reducing sugars presented a low reactivity even at the highest tested temperature (40°C). Furthermore, a site by site analysis was performed by MS/MS to determine the glycation sites which were mainly identified at Lys246, Lys248 and Lys324. This work points out the high probability of glycation reactions in some commercialized products and describes a useful method to characterize IVIg glycated products issued from reducing sugar excipients.

    Animal data indicate that greater intake of fats and sugars prevalent in a Western diet impairs hippocampal memory and tests of behavioral inhibition known to be related to hippocampal function (e.g., feature negative discrimination tasks). It has been argued that such high-fat high-sugar diets (HFS) impair the hippocampus, which then becomes less sensitive to modulation by physiological state. Thus retrieval of motivationally salient memories (e.g., when seeing or smelling food) occurs irrespective of state. Here we examine whether evidence of similar effects can be observed in humans using a correlational design. Healthy human participants (N = 94), who varied in their habitual consumption of a HFS diet, completed the verbal paired-associate (VPA) test, a known hippocampal-dependent process, as well as liking and wanting ratings of palatable snack foods, assessed both when hungry and when sated. Greater intake of a HFS diet was significantly associated with a slower VPA learning rate, as predicted. Importantly, for those who regularly consumed a HFS diet, though reductions in liking and wanting occurred between hungry and sated states, the reduction in wanting was far smaller relative to liking. The latter effect was strongly related to VPA learning rate, suggestive of hippocampal mediation. In agreement with the animal literature, human participants with a greater intake of a HFS diet show deficits in hippocampal-dependent learning and memory, and their desire to consume palatable food is less affected by physiological state-a process we suggest that is also hippocampal related.

    The impact of sugar restriction on subsequent sugar intake by overweight adolescents is unknown. Our aim was to examine the effect of sugar restriction on subsequent ad libitum sugar intake by overweight adolescents and whether habitual sugar intake and impulsivity influence the effect of sugar restriction on subsequent sugar intake. This was an in-laboratory crossover feeding trial with sugar-exposure and sugar-restriction conditions. Eighty-seven overweight Latino and African-American adolescents underwent both meal conditions in two separate 8-hour in-laboratory visits. Participants had access to ad libitum snack trays for 3 hours after the condition-specific meals. Ad libitum sugar intake during the snack period was measured at each visit. Habitual sugar intake and impulsivity were assessed at baseline. Repeated measures analysis of covariance was used to examine the within-person effect of meal condition on ad libitum sugar intake. Mixed models were used to examine the moderating effects of habitual sugar intake and impulsivity on the meal condition-ad libitum sugar intake relationship. Participants consumed more ad libitum sugar during the snack period in the sugar-restriction condition than in the sugar-exposure condition (sugar restriction=78.63±38.84 g, sugar exposure=70.86±37.73 g; F=9.64, P=0.002). There was no relationship between habitual sugar intake and how much ad libitum sugar participants consumed during either condition. Higher impulsivity was associated with greater ad libitum sugar intake during both conditions (sugar restriction: b=.029, standard error=.01, Poverweight adolescents restricted from sugar intake consume greater amounts of sugar when they are later given access to high-sugar foods. Overweight adolescents with higher impulsivity appear to consume greater amounts of sugar regardless of previous levels of sugar consumption. Compensatory sugar intake and trait impulsivity may have implications for dietary interventions in this

  5. The Effect of Price and Socio-Economic Level on the Consumption of Sugar-Sweetened Beverages (SSB): The Case of Ecuador.

    2016-01-01

    The objective of this article is to estimate the own-price, cross-price and income elasticities of demand for SSB in Ecuador, as an indispensable step for predicting a reduction in the consumption of said beverages caused by the potential implementation of taxes in Ecuador. In addition, the own-price, cross-price and income elasticities of sugar-free substitutes like mineral water and diet soft drinks and juices are also estimated. The data from the 2011-2012 ENIGHUR, which contains detailed information on household consumption and socioeconomic variables, was used. The estimates are done using Deaton's Almost Ideal Demand System (AIDS) which accounts for differences in the quality of goods purchased. This demand system is estimated for different socio-economic groups, according to total household expenditure. The results reveal own-price elasticities for SSB between -1.17 and -1.33 depending on the socio-economic group, in line with the existing evidence for developed countries. Own-price elasticity for non-SSB is between -1 and -1.24. Income elasticities reveal that both SSB and non-SSB are normal goods with elasticities decreasing for higher socio-economic groups. These results show that the consumption of SSB is sensitive to price changes, meaning that the implementation of taxes on said beverages could be effective in reducing their consumption. The fact that non-SSB are also sensitive to price changes would indicate that subsidies could be implemented for the production of some of them.

    Sugars regulate the expression of many genes at the transcriptional level. In Arabidopsis thaliana, sugars induce or repress the expression of >1800 genes, including the STP1 (SUGAR TRANSPORTER PROTEIN 1) gene, which encodes an H+/monosaccharide cotransporter. STP1 transcript levels decrease more rapidly after the addition of low concentrations of sugars than the levels of other repressed genes, such as DIN6 (DARK-INDUCED 6). We found that this regulation is exerted at the transcriptional level and is initiated by phosphorylatable sugars. Interestingly, the sugar signal that modulates STP1 expression is transmitted through a HEXOKINASE 1-independent signalling pathway. Finally, analysis of the STP1 5′ regulatory region allowed us to delimit a region of 309bp that contains the cis elements implicated in the glucose regulation of STP1 expression. Putative cis-acting elements involved in this response were identified. PMID:25281700

    In a field experiment Sugar beet Beta vulgaris was grown as a spring crop during the growing seasons of 2004 and 2006, in salt affected soil, previously planted with sesbania and barley (2005 and 2003) to evaluate the response of sugar beet to two irrigation methods, (drip fertigation and surface irrigation), different levels of nitrogen fertilizer and its effect on yield and quality. Different rates of nitrogen fertilizers (0, 50, 100, 150 and 200 kg N/ ha) as urea (46% N) were injected for drip irrigation or broadcasted for the surface-irrigated treatments in four equally split applications. The 15 N labelled urea was applied to sub-plots of 1.0 m 2 in each experimental unit in a manner similar to that of unlabeled urea. Irrigation scheduling was carried out using the direct method of neutron scattering technique. Sugar beet was irrigated when soil moisture in the upper 25 cm was 80% of the field capacity (FC) and such practice continued until the six leaf stage. From the latter stage until harvest, sugar beet was irrigated when soil moisture in the upper 50 cm reached 80% of the FC. The amount of irrigation water applied, electrical conductivity of the soil paste, dry matter and fresh roots yield, total nitrogen uptake and N derived from fertilizer were also determined. Furthermore, Nitrogen use as well as water use-efficiencies for dry matter and roots yield were also calculated. Results revealed that sugar beets and dry matter yield increased with increasing N input up to 100-150 kg N/ha which was indicated by the higher dry matter yield, and sugar beet yield. Sugar percentage was also increased relative to the average percentage recorded in Syria. Crop water use efficiencies, for both the drip-fertigated and surface-irrigated treatments were increased in most cases with increasing rate of nitrogen fertilizer. During the course of this study, small increases in soil salinity under both irrigation methods were observed. Higher increases in soil salinity was

    2015-02-21

    Sugar-sweetened beverages (SSBs) have been stressed as relevant targets of public health interventions considering the negative outcomes derived from their excessive intake. Though the evidence from published literature grows to support a cause-and-effect association of SSBs with obesity and other diseases, little is known on the effectiveness that strategies alone or as part of multi-component programmes have had to influence this particular dietary behaviour across all ages. Therefore, this review and meta-analysis aim to evaluate the effect that interventions have had to decrease their consumption or increase water intake in children and adults so as to guide the design of future programmes and inform policy making. Included studies in this review will be randomised controlled trials and quasi-experimental interventions (with a control group) that have reported baseline and post-intervention intakes of SSBs or water and that have been published from 1990 in any language. A thorough search will be performed in MEDLINE, EMBASE, Scopus, Web of Science, Cochrane's central register of controlled trials, and the Global Health Library. Two independent reviewers will conduct initial screening of potentially included articles and will later extract data to analyse domains of intervention design and delivery (with emphasis on behaviour change techniques used as rationale), as well as results in changes on consumption patterns and behavioural determinants. Internal and external validity of each study will also be appraised. A meta-analysis will be performed if a sufficient number of studies are available, and if not, a narrative review will be conducted instead. The results from this review aim to strengthen public health initiatives tackling obesity through improvements in non-alcoholic drinking patterns. As a subject of growing attention globally, this review will help determine which strategies available are the most effective in different contexts. Knowledge gained

    Full Text Available Background and Aim: Kombucha tea is made through fermentation of sweet tea by Kombucha fungus. It has beneficial therapeutic effects in the treatment of many diseases. The present study aimed at examining the effect of Kombucha tea extract on blood sugar and blood lipid profiles in diabetes. Materials and Methods: Twenty-eight Wistar rats weighing about 250g were divided into 4 equal groups and then injected intraperitoneally (IP with alloxan to induce diabetes. The administered concentrations were 20 and 80 mg/kg of Kombucha tea and 20 mg/kg of black ordinary tea for one month. The rats’ blood sugar and weight were tested before and after the intervention period but blood lipid parameters per either administration were also assessed at the end of the period. Results: Mean blood sugar in the diabetic rats receiving Kombucha tea was reduced. Maximum reduction in blood sugar was observed in the group receiving Kombucha tea with concentration of 80 mg/kg. However, black tea significantly reduced blood sugar. Conclusion: Kombucha tea consumption for a month only reduced blood sugar levels in diabetic patients. But increased the weight and not have favorable effects on lipid profile.

    To contribute evidence and make recommendations to assist in achieving free sugars reduction, with due consideration to the broader picture of weight management and dietary quality. An expert workshop in July 2016 addressed options outlined in the Public Health England report 'Sugar reduction: The evidence for action' that related directly to the food industry. Panel members contributed expertise in food technology, public heath nutrition, marketing, communications, psychology and behaviour. Recommendations were directed towards reformulation, reduced portion sizes, labelling and consumer education. These were evaluated based on their feasibility, likely consumer acceptability, efficacy and cost. The panel agreed that the 5% target for energy from free sugars is unlikely to be achievable by the UK population in the near future, but a gradual reduction from average current level of intake is feasible. Progress requires collaborations between government, food industry, non-government organisations, health professionals, educators and consumers. Reformulation should start with the main contributors of free sugars in the diet, prioritising those products high in free sugars and relatively low in micronutrients. There is most potential for replacing free sugars in beverages using high-potency sweeteners and possibly via gradual reduction in sweetness levels. However, reformulation alone, with its inherent practical difficulties, will not achieve the desired reduction in free sugars. Food manufacturers and the out-of-home sector can help consumers by providing smaller portions. Labelling of free sugars would extend choice and encourage reformulation; however, government needs to assist industry by addressing current analytical and regulatory problems. There are also opportunities for multi-agency collaboration to develop tools/communications based on the Eatwell Guide, to help consumers understand the principles of a varied, healthy, balanced diet.

  20. Sugars as tobacco ingredient: Effects on mainstream smoke composition.

    Science.gov (United States)

    2006-11-01

    Sugars are natural tobacco components, and are also frequently added to tobacco during the manufacturing process. This review describes the fate of sugars during tobacco smoking, in particular the effect of tobacco sugars on mainstream smoke composition. In natural tobacco, sugars can be present in levels up to 20 wt%. In addition, various sugars are added in tobacco manufacturing in amounts up to 4 wt% per sugar. The added sugars are usually reported to serve as flavour/casing and humectant. However, sugars also promote tobacco smoking, because they generate acids that neutralize the harsh taste and throat impact of tobacco smoke. Moreover, the sweet taste and the agreeable smell of caramelized sugar flavors are appreciated in particular by starting adolescent smokers. Finally, sugars generate acetaldehyde, which has addictive properties and acts synergistically with nicotine in rodents. Apart from these consumption-enhancing pyrolysis products, many toxic (including carcinogenic) smoke compounds are generated from sugars. In particular, sugars increase the level of formaldehyde, acetaldehyde, acetone, acrolein, and 2-furfural in tobacco smoke. It is concluded that sugars in tobacco significantly contribute to the adverse health effects of tobacco smoking.

  1. THE FACTORS FORMING QUALITY OF GRANULATED SUGAR

    Directory of Open Access Journals (Sweden)

    N. G. Kulneva

    2015-01-01

    Full Text Available Sugar, with good taste and high caloric, is one of the most popular human food. Consumers sugar must be sure that the sugar under normal conditions of use is of high quality and is not harmful to the health of the product. One reason for the decline in the quality of sugar is bacterial contamination. This is because the sugar industry products are good targets for the development of different groups of microorganisms, e.g., Bacillus subtilis, Clostridium perfringes, Leuconostoc dextranicum, Torula alba, Pseudomonas fluorescens, Sarcina lutea and others. These organisms are affected with beets, and then with sugar beet chips and diffusion juice fall into the processing line of sugar production. Their number in the diffusion juice varies and depends on many facto rs such as the quality of raw materials, the quality of cleaning beet root colonization of transporter-washing and the supply of water to the diffusion process, the temperature of the diffusion and others. In the diffusion unit has the most favorable conditions for the development of micro-organisms. Some of them, especially resistant bacteria and thermophilic bacteria or their spores, forming a capsule which protects against external influences occur in the final product sugar. When injected into the fresh crop of product (juice, syrup, they begin to multiply rapidly, causing difficulties in the process. The higher seeding beet microorganisms, the more they decompose and emit sucrose metabolism byproducts. To reduce the negative impact of microbiological and reduce losses from decomposition of sucrose conducted research on the possibility of using chlorine-containing substances in the sugar industry. It was established experimentally that the investigated chlorinated drug has bacteriostatic action and can be recommended for use in sugar beet production.

  2. Characteristics of sugar uptake by immature maize embryos

    1986-01-01

    Characteristics of sugar uptake by immature maize embryos were determined in vitro utilizing a 14 C-sugar solution incubation method. Hexose uptake rates were greater than those for sucrose, however, all showed biphasic kinetics. Glucose and fructose saturable components were evidence at <50 mM and sucrose at <5 mM. Chemical inhibitors (CCCP, DNP, NaCN, and PCMBS) and low temperature reduced sugar uptake. Sucrose influx was pH dependent while glucose was not. Embryos maintained a high sucrose to hexose ratio throughout development. At 25 days after pollination sucrose levels exceeded 200 mM while hexose levels remained below 5 mM. Glucose was rapidly converted to sucrose upon transport into the embryo. These circumstantial data indicate that sugar uptake by immature maize embryos is metabolically dependent and carrier mediated. Furthermore, sucrose transport appears to occur against its concentration gradient involving a H+/sucrose cotransport mechanism, while glucose influx is driven by its concentration gradient and subsequent metabolism

    Lignocellulose is an alternative fiber source for dogs; however, it has not yet been studied as a feed ingredient for the nutrition of dogs. Eight adult Beagles were involved in the study, which consisted of 3 feeding periods of 8 to 12 wk each. All dogs received 3 different diets, which either had the same concentration of fiber sources (2.7% sugar beet pulp or lignocellulose) or were formulated for a similar concentration of approximately 3% crude fiber: 12% sugar beet pulp (highSBP; 3.1% crude fiber), 2.7% sugar beet pulp (lowSBP; 0.96% crude fiber), or 2.7% lignocellulose (LC; 2.4% crude fiber). Feces samples were collected at the end of each feeding period, and the apparent nutrient digestibility, daily amount, and DM content of feces and fecal cell numbers of relevant bacteria were analyzed. The daily feces amount was lower and the feces DM was higher when dogs were fed the LC diet and the lowSBP diet compared with the highSBP diet ( dogs fed LC and lowSBP had lower concentrations of acetate ( dogs fed highSBP. The concentration of -butyrate was higher in the feces of dogs fed with LC compared with dogs fed high and low sugar beet pulp (SBP; dogs was highest followed by lowSBP- and highSBP-fed dogs ( dog feed has different impacts on the fecal microbiota and the apparent digestibility of nutrients. Therefore, different areas of application should be considered.

    A number of recommendations for policy and program interventions to limit excess free sugar consumption have emerged, however there are a lack of data describing the amounts and types of sugar in foods. This study presents an assessment of sugar in Canadian prepackaged foods including: (a) the first systematic calculation of free sugar contents; (b) a comprehensive assessment of total sugar and free sugar levels; and (c) sweetener and free sugar ingredient use, using the University of Toronto’s Food Label Information Program (FLIP) database 2013 (n = 15,342). Food groups with the highest proportion of foods containing free sugar ingredients also had the highest median total sugar and free sugar contents (per 100 g/mL): desserts (94%, 15 g, and 12 g), sugars and sweets (91%, 50 g, and 50 g), and bakery products (83%, 16 g, and 14 g, proportion with free sugar ingredients, median total sugar and free sugar content in Canadian foods, respectively). Free sugar accounted for 64% of total sugar content. Eight of 17 food groups had ≥75% of the total sugar derived from free sugar. Free sugar contributed 20% of calories overall in prepackaged foods and beverages, with the highest at 70% in beverages. These data can be used to inform interventions aimed at limiting free sugar consumption. PMID:27657125

This study presents an assessment of sugar in Canadian prepackaged foods including: (a the first systematic calculation of free sugar contents; (b a comprehensive assessment of total sugar and free sugar levels; and (c sweetener and free sugar ingredient use, using the University of Toronto’s Food Label Information Program (FLIP database 2013 (n = 15,342. Food groups with the highest proportion of foods containing free sugar ingredients also had the highest median total sugar and free sugar contents (per 100 g/mL: desserts (94%, 15 g, and 12 g, sugars and sweets (91%, 50 g, and 50 g, and bakery products (83%, 16 g, and 14 g, proportion with free sugar ingredients, median total sugar and free sugar content in Canadian foods, respectively. Free sugar accounted for 64% of total sugar content. Eight of 17 food groups had ≥75% of the total sugar derived from free sugar. Free sugar contributed 20% of calories overall in prepackaged foods and beverages, with the highest at 70% in beverages. These data can be used to inform interventions aimed at limiting free sugar consumption.

    To identify and review evidence on 1) the effectiveness of statutory and self-regulatory actions to reduce the volume, exposure or wider impact of advertising for foods high in fat, sugar and salt (HFSS) to children, and 2) the role of educational measures. A systematic review of three databases (Medline, CINAHL and PsycINFO) and grey literature was carried out. Relevant evidence included studies evaluating advertising bans and restrictions, advertising literacy programmes and parental communication styles. Relevant media included TV, internet, radio, magazines and newspaper advertising. No studies were excluded based on language or publication date. Forty-seven publications were included: 19 provided evidence for the results of statutory regulation, 25 for self-regulation, and six for educational approaches. Outcome measures varied in approach, quality and results. Findings suggested statutory regulation could reduce the volume of and children's exposure to advertising for foods HFSS, and had potential to impact more widely. Self-regulatory approaches showed varied results in reducing children's exposure. There was some limited support for educational measures. Consistency in measures from evaluations over time would assist the development and interpretation of the evidence base on successful actions and measures to reduce the volume, exposure and impact of advertising for foods HFSS to children.

    Sugar cane is a major source of food and fuel worldwide. Biotechnology has the potential to improve economically-important traits in sugar cane as well as diversify sugar cane beyond traditional applications such as sucrose production. High levels of transgene expression are key to the success of improving crops through biotechnology. Here we describe new molecular tools that both expand and improve gene expression capabilities in sugar cane. We have identified promoters that can be used to drive high levels of gene expression in the leaf and stem of transgenic sugar cane. One of these promoters, derived from the Cestrum yellow leaf curling virus, drives levels of constitutive transgene expression that are significantly higher than those achieved by the historical benchmark maize polyubiquitin-1 (Zm-Ubi1) promoter. A second promoter, the maize phosphonenolpyruvate carboxylate promoter, was found to be a strong, leaf-preferred promoter that enables levels of expression comparable to Zm-Ubi1 in this organ. Transgene expression was increased approximately 50-fold by gene modification, which included optimising the codon usage of the coding sequence to better suit sugar cane. We also describe a novel dual transcriptional enhancer that increased gene expression from different promoters, boosting expression from Zm-Ubi1 over eightfold. These molecular tools will be extremely valuable for the improvement of sugar cane through biotechnology.

    Full Text Available The sugar industry uses much water and produces a significant amount of wastewater for disposal. Efficient utilization of water is vital in the process industries not only to reduce the cost of the supply and discharge of freshwater associated with the process but also to minimize environmental problems associated with the use and discharge of water. This paper presents the analysis of fresh water used and wastewater discharged in a sugar manufacturing process. In order to reduce the load of the cooling water system. The system was modified to an open recirculation cooling water system. Also the excess condensate internal water and the discharged water from cooling water system were analyzed and optimized using pinch analysis and mathematical optimization techniques by Resource Conversation Networks spreadsheet software.

    Full Text Available Sugar, which can be extracted from sugar cane and sugar beet, is one of the most important ingredients of food. Conducting more research to increase the extraction efficiency of sugar is necessary due to high production of sugar beet and its numerous processing units in northern Khorasan province. In this research, the effect of temperature, time and the frequency of ultrasonic waves on mechanical properties of sugar beet and its extraction rate of sugar in moisture content of 75% were studied. In this regard, an ultrasonic bath in laboratory scale was used. The studied parameters and their levels were frequency in three levels (zero, 25 and 45 KHz, temperature in three levels (25, 50 and 70 ° C and the imposed time of ultrasonic waves in three levels (10, 20 and 30 min. Samples were prepared using planned experiments and the results were compared with control sugar beet samples. A Saccharimeter was used to measure the concenteration of sugar in samples. Two different types of probe including semi-spherical end and the other one with sharpened edges were used to measure mechanical properties. The studied parameters of frequency, temperature and time showed significant effect on sugar extraction and their resulted effect in optimized levels revealed up to 56% increase in sugar extraction compared with control samples. The obtained values of elastic modulus and shear modulus showed a decreasing trend. The obtained values of total energy of rupture, the total energy of shear, the maximum force of rupture, and the yield point of rupture showed an increasing trend. The frequency had no significant effect on the yield point of rupture and shear force.

    This study investigated the effect of increased high-intensity interval training (HIT) at the expense of total training volume on the stress and recovery levels of elite swimmers. Forty-one elite swimmers participated in the study and were randomly assigned to either a HIT or a control group (CON....... The Recovery Stress Questionnaire - Sport was used to measure the swimmers' stress and recovery levels. After the 12 week intervention, the general stress level was 16.6% (2.6-30.7%; mean and 95% CI) lower and the general recovery level was 6.5% (0.7-12.4%) higher in HIT compared to the CON, after adjusting...... for baseline values. No significant effects could be observed in sports-specific stress or sports-specific recovery. The results indicate that increasing training intensity and reducing training volume for 12 weeks can reduce general stress and increase general recovery levels in competitive swimmers....

    The mouse locomotor activation test of opiate action in a 2+2 dose parallel line assay was used in a repeated testing paradigm to determine the test, opiate and hexose specificities of a previously reported antagonism of morphine-induced antinocociception by hyperglycemia. In opiate specificity studies, fructose (5 g/kg, i.p.) significantly reduced the potency ratio for morphine and methadone, but not for levorphanol, meperidine or phenazocine when intragroup comparisons were made. In intergroup comparisons, fructose significantly reduced the potencies of levorphanol and phenazocine, but not methadone or meperidine. In hexose/polyol specificity studies, tagatose and fructose significantly reduced the potency ratio for morphine, whereas glucose, galactose, mannose and the polyols, sorbitol and xylitol, caused no significant decrease in potency. Fructose, tagatose, glucose and mannose (5 g/kg, i.p.) were tested for effects on brain morphine levels 30 min after morphine (60 min after sugar), and all four sugars significantly increased brain morphine relative to saline-pretreated controls. It is concluded that the antagonism of morphine by acute sugar administration shows specificity for certain sugars and occurs despite sugar-induced increases in the distribution of morphine to the brain. Furthermore, the effects of fructose show an opiate specificity similar to that of glucose on antinociception observed previously in our laboratory, except that methadone was also significantly inhibited in the present study, when a repeated-testing experimental design was used.

    Lower levels of 5-hydroxytryptamine (5-HT; serotonin) in the brain elicit sugar craving, while ingestion of sugar rich diet improves mood and alleviates anxiety. Gender differences occur not only in brain serotonin metabolism but also in a serotonin mediated functional responses. The present study was therefore designed to investigate gender related differences on the effects of long term consumption of sugar rich diet on the metabolism of serotonin in the hypothalamus and whole brain which may be relevant with the hyperphagic and anxiety reducing effects of sugar rich diet. Male and female rats were fed freely on a sugar rich diet for five weeks. Hyperphagic effects were monitored by measuring total food intake and body weights changes during the intervention. Anxiolytic effects of sugar rich diet was monitored in light-dark transition test. The results show that ingestion of sugar rich diet decreased serotonin metabolism more in female than male rats. Anxiolytic effects were elicited only in male rats. Hyperphagia was comparable in both male and female rats. Finings would help in understanding the role of sugar rich diet-induced greater decreases of serotonin in sweet craving in women during stress.

    The obesity epidemic has focused attention on relationships of sugars and sugar-sweetened beverages (SSB) to cardiovascular risk factors. Here we report cross-sectional associations of SSB, diet beverages, sugars with blood pressure (BP) for UK and USA participants of the International Study of Macro/Micro-nutrients and Blood Pressure (INTERMAP). Data collected includes four 24-h dietary recalls, two 24-h urine collections, eight BP readings, questionnaire data for 2,696 people ages 40-59 from 10 USA/UK population samples. Associations of SSB, diet beverages, and sugars (fructose, glucose, sucrose) with BP were assessed by multiple linear regression. Sugar-sweetened beverage intake related directly to BP, P-values 0.005 to Sugar-sweetened beverage intake higher by 1 serving/day (355 ml/24-h) was associated with systolic/diastolic BP differences of +1.6/+0.8 mm Hg (both P sugar-sodium interactions: for individuals with above-median 24-h urinary sodium excretion, fructose intake higher by 2 SD (5.6 %kcal) was associated with systolic/diastolic BP differences of +3.4/+2.2 mm Hg (both P sugar-BP differences for persons with higher sodium excretion, lend support to recommendations that intake of SSB, sugars, and salt be substantially reduced.

    Full Text Available Like many other industries, the sugar and sugar-bioproduct industries are facing important sustainability issues and opportunities. The relatively low and fluctuating profit for sugar, surpluses of sugar, world-wide trend to produce alternative, renewable bio-based fuels and chemicals to those derived from petroleum and reduce greenhouse gases, water- and energy-intensive factories and refineries, and increased consumer demands for sustainably manufactured products are putting pressure on the industries to diversify for sustainability. Sugar crops, including sugar and energy cane (Saccharum officinarum, sugar and energy beets (Beta vulgaris, and sweet sorghum (Sorghum bicolor L. Moench, are excellent, renewable biomass feedstocks because of their availability, their being amongst the plants that give the highest yields of carbohydrates per hectare, and high sugar contents. While much research has been focused on conversion technologies for advanced biofuels and bioproducts, attention is now focused on developing sustainable supply chains of sugar feedstocks for the new, flexible biorefineries, with customers wanting maximum feedstock reliability and quality, while minimizing cost. All biomass from sugar crops are potential feedstocks. The cogeneration of bioelectricity from bagasse and leaf residues is being increasingly manufactured in more countries and, due to the high carbon content of bagasse and leaves, can also be converted into value-added products such as biochar. Sugar crops are superior feedstocks for the production of platform chemicals for the manufacture of a range of end-products, e.g., bioplastics, chemicals, and biomaterials. In several countries and regions, green sustainability criteria are now in place and have to be met to count against national biofuel targets. Processes to convert high-fiber sugar crop biomass into biofuel have been developed but there has only been limited commercialization at the large-scale.

    Full Text Available Root rot diseases of sugar beet caused by Rhizoctonia solani (AG 2-2 IIIB and AG 2-2 IV, R. crocorum, Aphanomyces cochlioides, Phoma betae, Macrophomina phaeseolina, Fusarium oxysporum f.sp. radicis-betae, Pythium aphanidermatum Phytophthora drechsleri, Rhizopus stolonifer, R. arrhizus and Sclerotium rolfsii cause significant losses wherever sugar beets are grown. However, not all these soil-borne pathogens have been reported in all sugar beet production areas. Losses include reduced harvestable tonnage and reduced white sugar recovery. Many of these pathogens also cause post harvest losses in storage piles. Control for diseases caused by these pathogens include disease resistant cultivars, avoidance of stresses, cultural practices such as water management and the use of fungicides.

    The objective of the current study was to explore our hypothesis that average consumption of fructose and fructose containing sugars would not increase risk factors for cardiovascular disease (CVD) and the metabolic syndrome (MetS). A randomized, double blind, parallel group study was conducted where 267 individuals with BMI between 23 and 35 kg/m² consumed low fat sugar sweetened milk, daily for ten weeks as part of usual weight-maintenance diet. One group consumed 18% of calories from high fructose corn syrup (HFCS), another group consumed 18% of calories from sucrose, a third group consumed 9% of calories from fructose, and the fourth group consumed 9% of calories from glucose. There was a small change in waist circumference (80.9 ± 9.5 vs. 81.5 ± 9.5 cm) in the entire cohort, as well as in total cholesterol (4.6 ± 1.0 vs. 4.7 ± 1.0 mmol/L, p < 0.01), triglycerides (TGs) (11.5 ± 6.4 vs. 12.6 ± 8.9 mmol/L, p < 0.01), and systolic (109.2 ± 10.2 vs. 106.1 ± 10.4 mmHg, p < 0.01) and diastolic blood pressure (69.8 ± 8.7 vs. 68.1 ± 9.7 mmHg, p < 0.01). The effects of commonly consumed sugars on components of the MetS and CVD risk factors are minimal, mixed and not clinically significant.

    Ng, Shu Wen; Ostrowski, Jessica D; Li, Kuo-Ping

    2017-07-01

    Background: The US Food and Drug Administration's updated nutrition labeling requirements will include added sugars starting in July 2018, but no measure currently exists to identify the added sugar content of products and what it represents among purchases. Beverages are one of the first targets for reducing added sugar consumption, and hence are the focus here. Objective: Our goal was to estimate trends in added sugars in nonalcoholic packaged beverage products available in the United States and to estimate amounts of added sugars obtained from these beverages given the purchases of US households overall and by subpopulations. Design: On the basis of nutrition label data from multiple sources, we used a stepwise approach to derive the added sugar content of 160,713 beverage products recorded as purchased by US households in 2007-2012 (345,193 observations from 110,539 unique households). We estimated the amounts of added sugars obtained from packaged beverages US households reported buying in 2007-2008, 2009-2010, and 2011-2012, overall and by subpopulations based on household composition, race/ethnicity, and income. The key outcomes are added sugars in terms of per capita grams per day and the percentage of calories from packaged beverages. Results: Packaged beverages alone account for per capita consumption of 12 g/d of added sugars purchased by US households in 2007-2012, representing 32-48% of calories from packaged beverages. Whereas the absolute amount of added sugars from beverages has not changed meaningfully over time, the relative contribution of added sugars to calories from beverages has increased. Non-Hispanic black households and low-income households obtain both higher absolute and relative amounts of added sugars from beverages than non-Hispanic white households and high-income households (all P beverages at both the product level and the population level in the United States and can be used for comparisons after the revised nutrition labels are

    Full Text Available The American Heart Association (AHA and World Health Organization (WHO have recommended restricting calories from added sugars at lower levels than the Institute of Medicine (IOM recommendations, which are incorporated in the Dietary Guidelines for Americans 2010 (DGAs 2010. Sucrose (SUC and high fructose corn syrup (HFCS have been singled out for particular concern, because of their fructose content, which has been specifically implicated for its atherogenic potential and possible role in elevating blood pressure through uric acid-mediated endothelial dysfunction. This study explored the effects when these sugars are consumed at typical population levels up to the 90th percentile population consumption level for fructose. Three hundred fifty five overweight or obese individuals aged 20–60 years old were placed on a eucaloric diet for 10 weeks, which incorporated SUC- or HFCS-sweetened, low-fat milk at 8%, 18% or 30% of calories. There was a slight change in body weight in the entire cohort (169.1 ± 30.6 vs. 171.6 ± 31.8 lbs, p < 0.01, a decrease in HDL (52.9 ± 12.2 vs. 52.0 ± 13.9 mg/dL, p < 0.05 and an increase in triglycerides (104.1 ± 51.8 vs. 114.1 ± 64.7 mg/dL, p < 0.001. However, total cholesterol (183.5 ± 42.8 vs. 184.4 mg/dL, p > 0.05, LDL (110.3 ± 32.0 vs. 110.5 ± 38.9 mg/dL, p > 0.05, SBP (109.4 ± 10.9 vs. 108.3 ± 10.9 mmHg, p > 0.05 and DBP (72.1 ± 8.0 vs. 71.3 ± 8.0 mmHg, p > 0.05 were all unchanged. In no instance did the amount or type of sugar consumed affect the response to the intervention (interaction p > 0.05. These data suggest that: (1 when consumed as part of a normal diet, common fructose-containing sugars do not raise blood pressure, even when consumed at the 90th percentile population consumption level for fructose (five times the upper level recommended by the AHA and three times the upper level recommended by WHO; (2 changes in the lipid profile are mixed, but modest.

  3. Reduced heme levels underlie the exponential growth defect of the Shewanella oneidensis hfq mutant.

    Directory of Open Access Journals (Sweden)

    Christopher M Brennan

    Full Text Available The RNA chaperone Hfq fulfills important roles in small regulatory RNA (sRNA function in many bacteria. Loss of Hfq in the dissimilatory metal reducing bacterium Shewanella oneidensis strain MR-1 results in slow exponential phase growth and a reduced terminal cell density at stationary phase. We have found that the exponential phase growth defect of the hfq mutant in LB is the result of reduced heme levels. Both heme levels and exponential phase growth of the hfq mutant can be completely restored by supplementing LB medium with 5-aminolevulinic acid (5-ALA, the first committed intermediate synthesized during heme synthesis. Increasing expression of gtrA, which encodes the enzyme that catalyzes the first step in heme biosynthesis, also restores heme levels and exponential phase growth of the hfq mutant. Taken together, our data indicate that reduced heme levels are responsible for the exponential growth defect of the S. oneidensis hfq mutant in LB medium and suggest that the S. oneidensis hfq mutant is deficient in heme production at the 5-ALA synthesis step.

  5. Restricted cell elongation in Arabidopsis hypocotyls is associated with a reduced average pectin esterification level.

    Science.gov (United States)

    Derbyshire, Paul; McCann, Maureen C; Roberts, Keith

    2007-06-17

    Cell elongation is mainly limited by the extensibility of the cell wall. Dicotyledonous primary (growing) cell walls contain cellulose, xyloglucan, pectin and proteins, but little is known about how each polymer class contributes to the cell wall mechanical properties that control extensibility. We present evidence that the degree of pectin methyl-esterification (DE%) limits cell growth, and that a minimum level of about 60% DE is required for normal cell elongation in Arabidopsis hypocotyls. When the average DE% falls below this level, as in two gibberellic acid (GA) mutants ga1-3 and gai, and plants expressing pectin methyl-esterase (PME1) from Aspergillus aculeatus, then hypocotyl elongation is reduced. Low average levels of pectin DE% are associated with reduced cell elongation, implicating PMEs, the enzymes that regulate DE%, in the cell elongation process and in responses to GA. At high average DE% other components of the cell wall limit GA-induced growth.

    To evaluate the efficacy of operant conditioning in sustaining reduced noise levels in the neonatal intensive care unit (NICU). Quasi-experimental study on quality of care. Level III NICU of a teaching hospital in south India. 26 staff employed in the NICU. (7 Doctors, 13 Nursing staff and 6 Nursing assistants). Operant conditioning of staff activity for 6 months. This method involves positive and negative reinforcement to condition the staff to modify noise generating activities. Comparing noise levels in decibel: A weighted [dB (A)] before conditioning with levels at 18 and 24 months after conditioning. Decibel: A weighted accounts for noise that is audible to human ears. Operant conditioning for 6 months sustains the reduced noise levels to within 62 dB in ventilator room 95% CI: 60.4 - 62.2 and isolation room (95% CI: 55.8 - 61.5). In the preterm room, noise can be maintained within 52 dB (95% CI: 50.8 - 52.6). This effect is statistically significant in all the rooms at 18 months (P = 0.001). At 24 months post conditioning there is a significant rebound of noise levels by 8.6, 6.7 and 9.9 dB in the ventilator, isolation and preterm room, respectively (P =0.001). Operant conditioning for 6 months was effective in sustaining reduced noise levels. At 18 months post conditioning, the noise levels were maintained within 62 dB (A), 60 dB (A) and 52 dB (A) in the ventilator, isolation and pre-term room, respectively. Conditioning needs to be repeated at 12 months in the ventilator room and at 18 months in the other rooms.

    Full Text Available Summary. Producing high quality intermediate products in the boiling-crystallization station is an actual problem of sugar production. In the production of white sugar brown sugar syrup is not further purified that decreases the quality of the end product. Studies have been conducted using cellulose as an adsorbent for the purification of concentrated sugar solutions, having affinity to dyes and other impurities. Research have been carried out with the intermediate products of the Lebedyan sugar plant. Test results have shown cellulose ability to adsorb the dyes in sugar production. The influence of the adsorbent concentration and the mass fraction of solids in the syrup on the decolorization effect has been studied; rational process parameters have been obtained. It has been found that proceeding an additional adsorption purification of brown sugars syrup allows to reduce the solution color, increase the amount and quality of the end product. Adsorbing means, received from production wastes on the basis of organic resources, have many advantages: economical, environmentally friendly for disposal, safe to use, reliable and efficient in use. Conducted research on using cellulose as adsorbent for treatment of concentrated sugar solutions, having an affinity for colouring matter and other impurities. The experiments were carried out on the intermediates Lebedyanskiy sugar factory. The test results showed the ability of cellulose to adsorb coloring matter of sugar production. To evaluate the effect of bleaching depending on the mass fraction of dry substances prepared yellow juice filtration of sugar concentration of 55, 60, 65 % with subsequent adsorption purification of cellulose. The results of the experiment built adsorption isotherm of dyestuffs. The influence of the concentration of the adsorbent and a mass fraction of solids of juice filtration on the efficiency of decolorization obtained by rational parameters of the process. It is

  8. Increasing the maximally random jammed density with electric field to reduce the fat level in chocolate

    Tao, R.; Tang, H.

    Chocolate is one of the most popular food types and flavors in the world. Unfortunately, at present, chocolate products contain too much fat, leading to obesity. For example, a typical molding chocolate has various fat up to 40% in total and chocolate for covering ice cream has fat 50 -60%. Especially, as children are the leading chocolate consumers, reducing the fat level in chocolate products to make them healthier is important and urgent. While this issue was called into attention and elaborated in articles and books decades ago and led to some patent applications, no actual solution was found unfortunately. Why is reducing fat in chocolate so difficult? What is the underlying physical mechanism? We have found that this issue is deeply related to the basic science of soft matters, especially to their viscosity and maximally random jammed (MRJ) density φx. All chocolate productions are handling liquid chocolate, a suspension with cocoa solid particles in melted fat, mainly cocoa butter. The fat level cannot be lower than 1-φxin order to have liquid chocolate to flow. Here we show that that with application of an electric field to liquid chocolate, we can aggregate the suspended particles into prolate spheroids. This microstructure change reduces liquid chocolate's viscosity along the flow direction and increases its MRJ density significantly. Hence the fat level in chocolate can be effectively reduced. We are looking forward to a new class of healthier and tasteful chocolate coming to the market soon. Dept. of Physics, Temple Univ, Philadelphia, PA 19122.

    Full Text Available Abstract Background Chronic kidney disease (CKD is a newly recognized high-risk condition for cardiovascular disease (CVD, and previous studies reported the changes in inflammation and oxidative stress in advanced stages of CKD. We compared the levels of serum biomarkers for inflammation and oxidative stress between subjects with normal and mildly reduced glomerular filtration rate (GFR. Methods The subjects were 182 participants of a health check-up program including those with normal (≥ 90 mL/min/1.73 m2, N = 79 and mildly reduced eGFR (60-89 mL/min/1.73 m2, N = 103 which was calculated based on serum creatinine, age and sex. We excluded those with reduced eGFR 2. No one had proteinuria. We measured serum levels of C-reactive protein (CRP and thioredoxin (TRX as the markers of inflammation and oxidative stress, respectively. Results As compared with subjects with normal eGFR, those with mildly reduced eGFR had increased levels of both CRP and TRX. Also, eGFR was inversely correlated with these biomarkers. The associations of eGFR with these biomarkers remained significant after adjustment for age and sex. When adjustment was done for eight possible confounders, CRP showed significant association with systolic blood pressure, high density lipoprotein cholesterol (HDL-C and non-HDL-C, whereas TRX was associated with sex significantly, and with eGFR and systolic blood pressure at borderline significance. Conclusions We showed the increased levels of CRP and TRX in subjects with mildly reduced eGFR. The eGFR-CRP link and the eGFR-TRX link appeared to be mediated, at least partly, by the alterations in blood pressure and plasma lipids in these subjects.

  10. Oxidative stress reduces levels of dysbindin-1A via its PEST domain.

    Oxidative stress resulting from the generation of reactive oxygen species has been proposed as an etiological factor in schizophrenia. The present study tests the hypothesis that oxidative stress can affect levels of dysbindin-1A, encoded by Dtnbp1, a genetic risk factor for schizophrenia, via its PEST domain. In vitro studies on SH-SY5Y cells indicate that oxidative stress triggers proteasomal degradation of dysbindin-1A, and that this requires interactions with its PEST domain, which may be a TRIM32 target. We specifically found (a) that oxidative stress induced in SH-SY5Y cells by 500 µM hydrogen peroxide reduced levels of full-length dysbindin-1, but did not reduce levels of that protein lacking its PEST domain and (b) that levels of full-length dysbindin-1, but not dysbindin-1 lacking its PEST domain, were higher in cells treated with the proteasome inhibitor MG132. Oxidative stress thus emerges as the first known cellular factor regulating dysbindin-1 isoforms with PEST domains. These findings are consistent with the previously noted fact that phosphorylation of PEST domains often marks proteins for proteasomal degradation, and raises the possibility that treatments reducing oxidative stress in the brain, especially during development, may lower schizophrenia risk.

    Regulatory changes in Canada will require food labels to have a benchmark [% Daily Value, %DV] for total sugars, based on 100 g/day, while US labels will require a %DV for added sugars, based on 50 g/day. The objective of this study was to compare two labelling policies, a total sugars DV (100 g/day) and a free sugars DV (50 g/day) on food labels. This cross-sectional analysis of the Food Label Information Program database focussed on top sources of total sugars intake in Canada (n = 6924 foods). Products were categorized as "less healthy" using two sets of criteria: a) free sugars levels exceeding the WHO guidelines (≥10% energy from free sugars); and b) exceeding healthfulness cut-offs of the Food Standards Australia New Zealand Nutrient Profiling Scoring Criterion (FSANZ-NPSC). The proportion of "less healthy" products with ≥15%DV (defined as "a lot" of sugars i.e. high in sugars, based on Health Canada's %DV labelling footnote and educational message for dietary guidance) were compared for each sugar labelling scenario. The free sugars DV showed better alignment with both methods for assessing "healthfulness" than the total sugars DV. The free sugars DV identified a greater proportion of "less healthy" foods with ≥15%DV, based on both the FSANZ-NPSC (70% vs. 45%, p chocolate bars, confectionery, and frozen desserts categories. Compared to total sugars DV labelling, using a free sugars DV identified more "less healthy" foods. Findings support the adoption of free sugars labelling. Copyright © 2018 Elsevier Inc.

    Excess sugar intake increases risk for obesity and related comorbidities among children. The World Health Organization (WHO), American Heart Association (AHA) and the 2015 USDA dietary recommendations have proposed guidelines for added sugar intake to reduce risk for disease. WHO and USDA recommendations are presented as a percentage of daily calories from added sugar. This approach is not easily understood or translated to children, where energy needs increase with age. The AHA recommendation is based on a fixed value of 25 g of added sugar for all children 2-19 years of age. This approach does not take into account the different levels of intake across this wide age range. Due to these limitations, we adapted current recommendations for added sugars based on daily energy needs of children 2-19 years. We used those values to derive simple regression equations to predict grams or teaspoons of added sugars per day based on age that would be equivalent to 10% of daily energy needs. This proposed approach aligns with the changing nutritional needs of children and adolescents during growth. © 2017 World Obesity Federation.

    Dental caries affects ≤80% of the world’s population with almost a quarter of US adults having untreated caries. Dental caries is costly to health care and negatively affects well-being. Dietary free sugars are the most important risk factor for dental caries. The WHO has issued guidelines that recommend intake of free sugars should provide ≤10% of energy intake and suggest further reductions to caries risk, which showed evidence of moderate quality from cohort studies that limiting free sugars to ≤10% of energy reduced, but did not eliminate, dental caries. Even low levels of dental caries in children are of concern because caries is a lifelong progressive and cumulative disease. The systematic review therefore explored if there were further benefits to dental health if the intake of free sugars was limited to caries when free sugar intake was 5% but ≤10% of energy. The WHO recommendations are intended for use by policy makers as a benchmark when assessing intake of sugars by populations and as a driving force for policy change. Multiple strategies encompassing both upstream and downstream preventive approaches are now required to translate the recommendations into policy and practice. PMID:26773022

    Graphical abstract: Self-glazing red mud based ceramic materials (RMCM) were produced by normal pressure sintering process using the main raw materials of red mud. The properties of the RMCM samples were investigated by the measurements of mechanical properties, radiation measurement, X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results show that the self-glazing RMCM have good mechanical properties (water absorption and apparent porosity approached zero; bulk density, 2.94 g/cm{sup 3}; compressive strength, 78.12 MPa). The radiation level has clear change regularity that the radioactivity levels of red mud (6360 Bq) are obvious declined, and can be reduced to that of the natural radioactive background of Guilin Karst landform, China (3600 Bq). It will not only consume large quantities of red mud, but also decrease the production cost of self-glazing RMCM. And the statement of this paper will offer effective ways to reduce the radioactivity level of red mud.

  16. Inhibition of hyaluronan synthesis reduces versican and fibronectin levels in trabecular meshwork cells.

    Directory of Open Access Journals (Sweden)

    Full Text Available Hyaluronan (HA is a major component of the extracellular matrix (ECM and is synthesized by three HA synthases (HAS. Similarities between the HAS2 knockout mouse and the hdf mutant mouse, which has a mutation in the versican gene, suggest that HA and versican expression may be linked. In this study, the relationship between HA synthesis and levels of versican, fibronectin and several other ECM components in trabecular meshwork cells from the anterior segment of the eye was investigated. HA synthesis was inhibited using 4-methylumbelliferone (4MU, or reduced by RNAi silencing of each individual HAS gene. Quantitative RT-PCR and immunoblotting demonstrated a reduction in mRNA and protein levels of versican and fibronectin. Hyaluronidase treatment also reduced versican and fibronectin levels. These effects could not be reversed by addition of excess glucose or glucosamine or exogenous HA to the culture medium. CD44, tenascin C and fibrillin-1 mRNA levels were reduced by 4MU treatment, but SPARC and CSPG6 mRNA levels were unaffected. Immunostaining of trabecular meshwork tissue after exposure to 4MU showed an altered localization pattern of HA-binding protein, versican and fibronectin. Reduction of versican by RNAi silencing did not affect HA concentration as assessed by ELISA. Together, these data imply that HA concentration affects synthesis of certain ECM components. Since precise regulation of the trabecular meshwork ECM composition and organization is required to maintain the aqueous humor outflow resistance and intraocular pressure homeostasis in the eye, coordinated coupling of HA levels and several of its ECM binding partners should facilitate this process.

    The clinical resistance of non-small cell lung cancer (NSCLC) to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) has been linked to EGFR T790M resistance mutations or MET amplifications. Additional mechanisms underlying EGFR-TKI drug resistance remain unclear. The present study demonstrated that icotinib significantly inhibited the proliferation and increased the apoptosis rate of HCC827 cells; the cellular mRNA and protein expression levels of phosphatase and tensin homolog (PTEN) were also significantly downregulated. To investigate the effect of PTEN expression levels on the sensitivity of HCC827 cells to icotinib, PTEN expression was silenced using a PTEN-specific small interfering RNA. The current study identified that the downregulation of PTEN expression levels may promote cellular proliferation in addition to decreasing the apoptosis of HCC827 cells, and may reduce the sensitivity of HCC827 cells to icotinib. These results suggested that reduced PTEN expression levels were associated with the decreased sensitivity of HCC827 cells to icotinib. Furthermore, PTEN expression levels may be a useful marker for predicting icotinib resistance and elucidating the resistance mechanisms underlying EGFR-mutated NSCLC.

    2011-09-01

    The application (WO2010141855) is in the field of glycobiology, and involves the control of the rate of fucosylation of proteins by exogenous factors. It aims at controlling the rate of protein fucosylation with inhibitors (drugs or nucleic acid antagonists) of enzymes involved in the synthesis of GDP-fucose. Mammalian cell lines were cultured in the presence of inhibitors, for example, siRNA. The rates of GDP-fucose in cells and during protein fucosylation were characterized. The level of protein fucosylation decreases rapidly in response to a decrease in GDP-fucose level. The relationship between the rate of fucosylation of proteins and the level of GDP-fucose in a cell is non-linear. Reduction in the rate of protein fucosylation can be achieved with a minimal reduction of the level of GDP-fucose in cells. The paradigm may be used to synthesize proteins and antibodies, with a reduced rate of fucosylation. The application claims that the use of drugs or nucleic acid antagonists that inhibit the enzymes involved in GDP-fucose biosynthesis optimizes the level of GDP-fucose present in cells, and reduces the rate of fucosylation of glycoproteins.

    The climate benefit and economic cost of an international mechanism for reducing emissions from deforestation and degradation (REDD) will depend on the design of reference levels for crediting emission reductions. We compare the impacts of six proposed reference level designs on emission reduction levels and on cost per emission reduction using a stylized partial equilibrium model (the open source impacts of REDD incentives spreadsheet; OSIRIS). The model explicitly incorporates national incentives to participate in an international REDD mechanism as well as international leakage of deforestation emissions. Our results show that a REDD mechanism can provide cost-efficient climate change mitigation benefits under a broad range of reference level designs. We find that the most effective reference level designs balance incentives to reduce historically high deforestation emissions with incentives to maintain historically low deforestation emissions. Estimates of emission reductions under REDD depend critically on the degree to which demand for tropical frontier agriculture generates leakage. This underscores the potential importance to REDD of complementary strategies to supply agricultural needs outside of the forest frontier.

    Long-term exposure to stress or high glucocorticoid levels leads to depression-like behavior in rodents; however, the cause remains unknown. Increasing evidence shows that astrocytes, the most abundant cells in the central nervous system (CNS), are important to the nervous system. Astrocytes nourish and protect the neurons, and serve as glycogen repositories for the brain. The metabolic process of glycogen, which is closely linked to neuronal activity, can supply sufficient energy substrates for neurons. The research team probed into the effects of chronic corticosterone (CORT) exposure on the glycogen level of astrocytes in the hippocampal tissues of male C57BL/6N mice in this study. The results showed that chronic CORT injection reduced hippocampal neurofilament light protein (NF-L) and synaptophysin (SYP) levels, induced depression-like behavior in male mice, reduced hippocampal glycogen level and glycogen synthase activity, and increased glycogen phosphorylase activity. The results suggested that the reduction of the hippocampal glycogen level may be the mechanism by which chronic CORT treatment damages hippocampal neurons and induces depression-like behavior in male mice.

    Full Text Available When there is a mismatch between the cardinality of a periodic task set and the priority levels supported by the underlying hardware systems, multiple tasks are grouped into one class so as to maintain a specific level of confidence in their accuracy. However, such a transformation is achieved at the expense of the loss of schedulability of the original task set. We further investigate the aforementioned problem and report the following contributions: (i a novel technique for mapping unlimited priority tasks into a reduced number of classes that do not violate the schedulability of the original task set and (ii an efficient feasibility test that eliminates insufficient points during the feasibility analysis. The theoretical correctness of both contributions is checked through formal verifications. Moreover, the experimental results reveal the superiority of our work over the existing feasibility tests by reducing the number of scheduling points that are needed otherwise.

    Sugar consumption, especially added sugars, is under attack. Various government and health authorities have suggested new sugar recommendations and guidelines as low as 5% of total calories from free sugars. Definitions for total sugars, free sugars, and added sugars are not standardized, nor are there accepted nutrient databases for this information. Our objective was to measure total sugars and added sugars in sample meal plans created by the United States Department of Agriculture (USDA) and the Academy of Nutrition and Dietetics (AND). Utilizing the Nutrition Data System for Research (NDSR) nutritional database, results found that plans created by the USDA and AND averaged 5.1% and 3.1% calories from added sugar, 8.7% and 3.1% from free sugar, and 23.3% and 21.1% as total sugars respectively. Compliance with proposed added sugar recommendations would require strict dietary compliance and may not be sustainable for many Americans. Without an accepted definition and equation for calculating added sugar, added sugar recommendations are arbitrary and may reduce intakes of nutrient-rich, recommended foods, such as yogurt, whole grains, and tart fruits including cranberries, cherries, and grapefruit. Added sugars are one part of excess calorie intake; however, compliance with low added sugar recommendations may not be achievable for the general public.

    Full Text Available Lung diseases constitute an important public health problem and its growing level of concern has led to efforts for the development of new therapies, particularly for the control of lung inflammation. Low Level Laser Therapy (LLLT has been highlighted as a non-invasive therapy with few side effects, but its mechanisms need to be better understood and explored. Considering that pollution causes several harmful effects on human health, including lung inflammation, in this study, we have used formaldehyde (FA, an environmental and occupational pollutant, for the induction of neutrophilic lung inflammation. Our objective was to investigate the local and systemic effects of LLLT after FA exposure. Male Wistar rats were exposed to FA (1% or vehicle (distillated water during 3 consecutive days and treated or not with LLLT (1 and 5 hours after each FA exposure. Non-manipulated rats were used as control. 24 h after the last FA exposure, we analyzed the local and systemic effects of LLLT. The treatment with LLLT reduced the development of neutrophilic lung inflammation induced by FA, as observed by the reduced number of leukocytes, mast cells degranulated, and a decreased myeloperoxidase activity in the lung. Moreover, LLLT also reduced the microvascular lung permeability in the parenchyma and the intrapulmonary bronchi. Alterations on the profile of inflammatory cytokines were evidenced by the reduced levels of IL-6 and TNF-α and the elevated levels of IL-10 in the lung. Together, our results showed that LLLT abolishes FA-induced neutrophilic lung inflammation by a reduction of the inflammatory cytokines and mast cell degranulation. This study may provide important information about the mechanisms of LLLT in lung inflammation induced by a pollutant.

Thorough shredding of the beets then need no longer form part of the operation, and the protein compounds, which give rise to fuel oils, are extracted in small amounts only.

  14. Hydrogen gas alleviates oxygen toxicity by reducing hydroxyl radical levels in PC12 cells.

    Full Text Available Hyperbaric oxygen (HBO therapy through breathing oxygen at the pressure of above 1 atmosphere absolute (ATA is useful for varieties of clinical conditions, especially hypoxic-ischemic diseases. Because of generation of reactive oxygen species (ROS, breathing oxygen gas at high pressures can cause oxygen toxicity in the central nervous system, leading to multiple neurological dysfunction, which limits the use of HBO therapy. Studies have shown that Hydrogen gas (H2 can diminish oxidative stress and effectively reduce active ROS associated with diseases. However, the effect of H2 on ROS generated from HBO therapy remains unclear. In this study, we investigated the effect of H2 on ROS during HBO therapy using PC12 cells. PC12 cells cultured in medium were exposed to oxygen gas or mixed oxygen gas and H2 at 1 ATA or 5 ATA. Cells viability and oxidation products and ROS were determined. The data showed that H2 promoted the cell viability and inhibited the damage in the cell and mitochondria membrane, reduced the levels of lipid peroxidation and DNA oxidation, and selectively decreased the levels of •OH but not disturbing the levels of O2•-, H2O2, or NO• in PC12 cells during HBO therapy. These results indicated that H2 effectively reduced •OH, protected cells against oxygen toxicity resulting from HBO therapy, and had no effect on other ROS. Our data supported that H2 could be potentially used as an antioxidant during HBO therapy.

    Recent neuroscience research suggests that tinnitus may reflect synaptic loss in the cochlea that does not express in the audiogram but leads to neural changes in auditory pathways that reduce sound level tolerance (SLT). Adolescents (N = 170) completed a questionnaire addressing their prior experience with tinnitus, potentially risky listening habits, and sensitivity to ordinary sounds, followed by psychoacoustic measurements in a sound booth. Among all adolescents 54.7% reported by questionnaire that they had previously experienced tinnitus, while 28.8% heard tinnitus in the booth. Psychoacoustic properties of tinnitus measured in the sound booth corresponded with those of chronic adult tinnitus sufferers. Neither hearing thresholds (≤15 dB HL to 16 kHz) nor otoacoustic emissions discriminated between adolescents reporting or not reporting tinnitus in the sound booth, but loudness discomfort levels (a psychoacoustic measure of SLT) did so, averaging 11.3 dB lower in adolescents experiencing tinnitus in the acoustic chamber. Although risky listening habits were near universal, the teenagers experiencing tinnitus and reduced SLT tended to be more protective of their hearing. Tinnitus and reduced SLT could be early indications of a vulnerability to hidden synaptic injury that is prevalent among adolescents and expressed following exposure to high level environmental sounds.

    Summary Background Dislipidaemia and increased levels of apolipoprotein B (apoB) in individuals with obesity are risk factors for development of cardiovascular disease (CVD). The aim of this study was to investigate the effect of weight loss and weight maintenance with and without liraglutide treatment on plasma lipid profiles and apoB. Methods Fifty‐eight individuals with obesity (body mass index 34.5 ± 3.0 kg/m2 [mean ± SD]) were included in this study. After 8 weeks on a very low‐calorie diet (800 kcal/day), participants were randomized to weight maintenance with meal replacements with or without liraglutide (1.2 mg daily) for 1 year. Plasma samples from before and after weight loss and after 1 year of weight maintenance were subjected to nuclear magnetic resonance‐based lipidomics analysis. Results After an 8‐week low‐calorie diet, study participants lost 12.0 ± 2.9 kg (mean ± SD) of their body weight, which was reflected in their lipid profiles (80 out of 124 lipids changed significantly), including reduced levels of apoB, total cholesterol, free cholesterol, remnant cholesterol, triglycerides, low‐density lipoprotein and very low‐density lipoprotein subclasses. After 1 year of maintained weight loss, the majority of the lipids had returned to pre‐weight loss levels even though weight loss was successfully maintained in both groups. Interestingly, apoB levels remained low in the liraglutide treated group (apoB change: 0.03 ± 0.02 mmol/L, p = 0.4) in contrast to an increase in the control group (apoB change: 0.06 ± 0.07 mmol/L, p = 0.02). Conclusion An 8‐week low‐calorie diet, in individuals with obesity, reduced plasma levels of lipids and the atherogenic marker apoB. After 1 year of weight maintenance, only study participants treated with liraglutide maintained reduced levels of apoB, despite similar body weight maintenance. Treatment with liraglutide may therefore reduce apoB levels and thus reflect lower

    The use of biomass as primary fuel for power and steam production using modern conversion technology such as the Biomass Integrated Gas Turbine/Combined Cycle (BIG/CC) has both technical and commercial potential. Brazil is implementing a BIG/CC Demonstration Plant to burn wood from eucalyptus short rotation forest and to test sugar cane bagasse as feedstock. The purpose of this project is to demonstrate the commercial viability of using biomass as a feedstock for power generation, its suitability for applications in developing countries, and the possibilities it offers for commercial activities in regions which currently have a low level of economic activities. The purpose of this paper is to show the potential applicability of this technology in the sugar cane industries of Developing Countries such as Brazil. The same quantity of sugar cane already processed in each sugar mill can produce sizable quantities of electric power at competitive costs, in addition to the traditional products -- sugar and/or ethanol, which will cause an economical impact, duplicating the revenue of these industries. The application of the BIG/CC technology in the Sugar Cane Industry may lead to the following scenario in developing countries: (1) power shall be produced at very competitive prices by specialized private firms associated with sugar mills; (2) plant sizes will be smaller -- 15 to 100 MW -- when based on biomass, a compared to large fossil fuel plants now prevailing; (3) ethanol and sugar production costs will be reduced due to more efficient and economical processes and due to the additional revenue from power production; (4) becoming more competitive with gasoline, ethanol production tends to increase, which will influence the automobile industry and improve the quality of life in big cities.

    To analyse available review-level evidence on the effectiveness of population-level interventions in non-clinical settings to reduce alcohol consumption or related health or social harm. Health, social policy and specialist review databases between 2002 and 2012 were searched for systematic reviews of the effectiveness of population-level alcohol interventions on consumption or alcohol-related health or social outcomes. Data were extracted on review research aim, inclusion criteria, outcome indicators, results, conclusions and limitations. Reviews were quality-assessed using AMSTAR criteria. A narrative synthesis was conducted overall and by policy area. Fifty-two reviews were included from ten policy areas. There is good evidence for policies and interventions to limit alcohol sale availability, to reduce drink-driving, to increase alcohol price or taxation. There is mixed evidence for family- and community-level interventions, school-based interventions, and interventions in the alcohol server setting and the mass media. There is weak evidence for workplace interventions and for interventions targeting illicit alcohol sales. There is evidence of the ineffectiveness of interventions in higher education settings. There is a pattern of support from the evidence base for regulatory or statutory enforcement interventions over local non-regulatory approaches targeting specific population groups. © 2013.

Using differentiated HL60 cells as a neutrophil model, here we show that generation of extracellular O2 (. - by the nicotinamide adenine dinucleotide (NADPH oxidase complex is increased by intracellular glutathione depletion.

    Grape contains flavonoids with antioxidant properties which are believed to be protective against various types of cancer. This antioxidative protection is possibly provided by the effective scavenging of reactive oxygen species (ROS), thus defending cellular DNA from oxidative damage and potential mutations. This study of healthy adults tested whether a daily regimen of grape juice supplementation could reduce cellular DNA damage in peripheral lymphocytes and reduce the amount of free radicals released. Sixty-seven healthy volunteers (16 women and 51 men) aged 19-57 years were given 480 ml of grape juice daily for 8 weeks in addition to their normal diet, and blood samples were drawn before and after the intervention. The DNA damage was determined by using the single cell gel (comet) assay with alkaline electrophoresis and was quantified by measuring tail length (TL). Levels of free radicals were determined by reading the lucigenin-perborate ROS generating source, using the Ultra-Weak Chemiluminescence Analyzer System. Grape juice consumption resulted in a significant decrease in lymphocyte DNA damage expressed by TL (before supplementation: 88.75±1.55 μm versus after supplementation: 70.25±1.31 μm; P=0.000 by paired t-test). Additionally, grape juice consumption for 8 weeks reduced the ROS/photon count by 15%, compared to the beginning of the study. The preventive effect of grape juice against DNA damage was simultaneously shown in both sexes. These results indicate that the consumption of grape juice may increase plasma antioxidant capacity, resulting in reduced DNA damage in peripheral lymphocytes achieved at least partially by a reduced release of ROS. Our findings support the hypothesis that polyphenolic compounds contained in grape juice exert cancer-protective effects on lymphocytes, limiting oxidative DNA damage possibly via a decrease in free radical levels

    Accumulation of reducing sugars (i.e. glucose and fructose) in plant roots has been consistently correlated with forest dieback and decline and, therefore, has potential as a biological indicator of ecosystem stress. In this study, the relationships between acidic deposition and `natural` (temperature, mycorrhizae, and nutrition) factors with first-year sugar maple seedling root sugar concentrations and growth were assessed in two sugar maple dominated forests in Michigan. Seedlings at the southern site (Wellston) had greater root growth, phosphorus, total sugar, and sucrose concentrations in roots, but lower reducing sugar concentration in roots. In addition, percent root length colonized by vesicular-arbuscular mycorrhizal fungi was less than that found for seedlings growing at the northern site (Alberta). Throughfall deposition of nitrate, sulfate, and hydrogen ions was not significantly correlated with seedling total or reducing sugar concentration. Total sugar concentration in seedling roots was positively correlated with air and soil temperatures at the southern site, but not at the northern site. Seedling tissue phosphorus concentration was correlated with total sugars at both sites, with sucrose at the southern site, and reducing sugars at the northern site. Mycorrhizal colonization rates at the Alberta site were positively correlated with reducing sugar concentration in seedling roots and negatively correlated with sucrose concentration. The results suggest that differences in seedling root sugar concentrations in these two forests are related to seedling root growth and are most likely due to ecological variables, such as available soil phosphorus, temperature, and growing season length through some complex interaction with mycorrhizae rather than acidic deposition stress. 56 refs., 3 figs.

    Equine protozoal myeloencephalitis (EPM) is a disease of horses that is primarily associated with infection with the apicomplexan Sarcocystis neurona. Infection with this parasite alone is not sufficient to induce the disease, and the mechanism of neuropathogenesis associated with EPM has not been reported. Nitric oxide (NO) functions as a neurotransmitter, a vasodilator, and an immune effector and is produced in response to several parasitic protozoa. The purpose of this work was to determine if the concentration of NO metabolites (NOx−) in the cerebrospinal fluid (CSF) is correlated with the development of EPM. CSF NOx− levels were measured before and after transport-stressed, acclimated, or dexamethasone-treated horses (n = 3 per group) were experimentally infected with S. neurona sporocysts. CSF NOx− levels were also compared between horses that were diagnosed with EPM after natural infection with S. neurona and horses that did not have clinical signs of disease or that showed no evidence of infection with the parasite (n = 105). Among the experimentally infected animals, the mean CSF NOx− levels of the transport-stressed group, which had the most severe clinical signs, was reduced after infection, while these values were found to increase after infection in the remaining groups that had less severe signs of EPM. Under natural conditions, horses with EPM (n = 65) had a lower mean CSF NOx− concentration than clinically normal horses with antibodies (Abs) against S. neurona (n = 15) in CSF, and horses that developed ataxia (n = 81) had a significantly lower mean CSF NOx− concentration than horses that did not have neurologic signs (n = 24). In conclusion, lower CSF NOx− levels were associated with clinical EPM, suggesting that measurement of CSF NOx− levels could improve the accuracy of diagnostic tests that are based upon detection of S. neurona-specific Abs in CSF alone and that reduced NO levels could be causatively related to the development

    The purpose of this research is to know the effect of garlic extract (GE) in reducing cholesterol level of broiler chicken by analyzing cholesterol level of broiler chicken blood. Two hundred one day broiler age were used in this study for 35 days. The chickens were randomly divided into four treatments, each treatment consist of five replications and each repetition consist of ten chickens. This research is used completely randomized design, such as: T0: 0% EBP, T1: 2%, T2: 4% and T3: 6%. Furthermore, at age 35 days each chicken was taken blood to be analyzed cholesterol levels, low density lipoprotein (LDL), high density lipoprotein (HDL) and calculated the ratio of LDL and HDL levels. The data obtained were analyzed using software from Statistical Product and Service Solution (SPSS 16.0). The results of significant analysis continued by Duncan’s New Multiple Range Test. Addition of GE from the 2% level decreases (P <0.05) of LDL and total cholesterol, and increases HDL and HDL-LDL ratio. The conclusions is obtained garlic extract plays an important role in lowering cholesterol levels of broiler meat.

    Full Text Available We have previously shown that the administration of fenofibrate to high-drinker UChB rats markedly reduces voluntary ethanol intake. Fenofibrate is a peroxisome proliferator-activated receptor alpha (PPARα agonist, which induces the proliferation of peroxisomes in the liver, leading to increases in catalase levels that result in acetaldehyde accumulation at aversive levels in the blood when animals consume ethanol. In these new studies, we aimed to investigate if the effect of fenofibrate on ethanol intake is produced exclusively in the liver (increasing catalase and systemic levels of acetaldehyde or there might be additional effects at central level. High drinker rats (UChB were allowed to voluntary drink 10% ethanol for 2 months. Afterward, a daily dose of fenofibrate (25, 50 or 100 mg/kg/day or vehicle (as control was administered orally for 14 days. Voluntary ethanol intake was recorded daily. After that time, animals were deprived of ethanol access for 24 h and administered with an oral dose of ethanol (1 g/kg for acetaldehyde determination in blood. Fenofibrate reduced ethanol voluntary intake by 60%, in chronically drinking rats, at the three doses tested. Acetaldehyde in the blood rose up to between 80 μM and 100 μM. Considering the reduction of ethanol consumption, blood acetaldehyde levels and body weight evolution, the better results were obtained at a dose of 50 mg fenofibrate/kg/day. This dose of fenofibrate also reduced the voluntary intake of 0.2% saccharin by 35% and increased catalase levels 2.5-fold in the liver but showed no effects on catalase levels in the brain. To further study if fenofibrate administration changes the motivational properties of ethanol, a conditioned-place preference experiment was carried out. Animals treated with fenofibrate (50 mg/kg/day did not develop ethanol-conditioned place preference (CPP.In an additional experiment, chronically ethanol-drinking rats underwent two cycles of ethanol

    Background: In January 2014, Mexico implemented a tax on sugar-sweetened beverage (SSB) purchases of 1 peso/L. Objective: We examined the heterogeneity of changes in nonalcoholic beverage (SSB and bottled water) purchases after the tax was implemented by household income, urban and rural strata, and household composition. Methods: We used 4 rounds of the National Income and Expenditure Surveys: 2008, 2010, 2012, and 2014. Changes in purchases in per capita liters per week were estimated with the use of 2-part models to adjust for nonpurchases. We compared absolute and relative differences between adjusted changes in observed purchases in 2014 with expected purchases in 2014 based on prior trends (2008-2012). The models were adjusted for sociodemographic characteristics of the households, place of residence, and lagged gross domestic product per capita. Results: We found a 6.3% reduction in the observed purchases of SSBs in 2014 compared with the expected purchases in that same year based on trends from 2008 to 2012. These reductions were higher among lower-income households, residents living in urban areas, and households with children. We also found a 16.2% increase in water purchases that was higher in low- and middle-income households, in urban areas, and among households with adults only. Conclusions: SSB purchases decreased and water purchases increased after an SSB tax was imposed in Mexico. The magnitude of these changes was greater in lower-income and urban households. © 2017 American Society for Nutrition.

    Artificially sweetened beverages (ASBs) are promoted as healthy alternatives to sugar-sweetened beverages (SSBs) in order to reduce sugar intake, but their effects on weight control and glycaemia have been debated. This study examines associations of SSBs and ASBs with energy and sugar intake and cardiometabolic measures. One thousand six hundred eighty-seven children aged 4-18 participated in the National Diet and Nutrition Survey Rolling Programme (2008/9-2011/12) in the UK. Linear regression was used to examine associations between SSBs and ASBs and energy and sugar, overall and from solid foods and beverages, and body mass index, waist-to-hip ratio and blood analytes. Fixed effects linear regression examined within-person associations with energy and sugar. Compared with non-consumption, SSB consumption was associated with higher sugar intake overall (6.1%; 4.2, 8.1) and ASB consumption with higher sugar intake from solid foods (1.7%; 0.5, 2.9) but not overall, mainly among boys. On SSB consumption days, energy and sugar intakes were higher (216 kcal; 163, 269 and 7.0%; 6.2, 7.8), and on ASB consumption days, sugar intake was lower (-1.0%; -1.8, -0.1) compared with those on non-consumption days. SSB and ASB intakes were associated with higher levels of blood glucose (SSB: 0.30 mmol L -1 ; 0.11, 0.49 and ASB: 0.24 mmol L -1 ; 0.06, 0.43) and SSB intake with higher triglycerides (0.29 mmol L -1 ; 0.13, 0.46). No associations were found with other outcomes. Sugar-sweetened beverage intake was associated with higher sugar intake and both SSBs and ASBs with a less healthy cardiometabolic profile. These findings add to evidence that health policy should discourage all sweetened beverage consumption. © 2017 World Obesity Federation.

  15. Restricted cell elongation in Arabidopsis hypocotyls is associated with a reduced average pectin esterification level

    Full Text Available Abstract Background Cell elongation is mainly limited by the extensibility of the cell wall. Dicotyledonous primary (growing cell walls contain cellulose, xyloglucan, pectin and proteins, but little is known about how each polymer class contributes to the cell wall mechanical properties that control extensibility. Results We present evidence that the degree of pectin methyl-esterification (DE% limits cell growth, and that a minimum level of about 60% DE is required for normal cell elongation in Arabidopsis hypocotyls. When the average DE% falls below this level, as in two gibberellic acid (GA mutants ga1-3 and gai, and plants expressing pectin methyl-esterase (PME1 from Aspergillus aculeatus, then hypocotyl elongation is reduced. Conclusion Low average levels of pectin DE% are associated with reduced cell elongation, implicating PMEs, the enzymes that regulate DE%, in the cell elongation process and in responses to GA. At high average DE% other components of the cell wall limit GA-induced growth.

    Priming a high level construal has been shown to enhance self-control and reduce preference for indulgent food. Subtle visual cues have been shown to enhance the effects of a priming procedure. The current study therefore examined the combined impact of construal level and a visual cue reminder on the consumption of energy-dense snacks. A student and community-based adult sample with a wide age and body mass index (BMI) range (N = 176) were randomly assigned to a high or low construal condition in which a novel symbol was embedded. Afterward participants completed a taste test of ad libitum snack foods in the presence or absence of the symbol. The high (vs. the low) construal level prime successfully generated more abstract responses (p snacks in the presence of a visual cue-reminder. This may be a practical technique for reducing overeating and has the potential to be extended to other unhealthy behaviors. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

    Marine organisms that occur in urbanised bays can be exposed to low-level chronic pollution that results in sublethal changes to behavior or reproduction. The effects of low levels of copper on the reproductive success of a mobile invertebrate were assessed. Free living flatworms are common predators of bivalves and barnacles. Flatworms (Stylochus pygmaeus) were exposed to low levels of copper ranging from 0 to 25 microg L(-1) in the presence and absence of their barnacle prey (Balanus variegatus). Flatworms laid fewer egg batches when exposed to copper and the hatching success of the eggs was also reduced. Exposure to 25 microg L(-1) copper for 10 d reduced the reproductive success of flatworms by up to 80%. Results were consistent regardless of the presence or absence of prey (barnacles). Barnacles were only moderately affected by copper but exhibited major avoidance behavior (feeding inhibition) in the presence of flatworm predators. This is the first ecotoxicological study on marine flatworms. Experiments are required to quantify the effects of flatworm predator populations on sessile invertebrate community structure in the field.

  18. Global 5-Hydroxymethylcytosine Levels Are Profoundly Reduced in Multiple Genitourinary Malignancies.

    Full Text Available Solid tumors are characterized by a plethora of epigenetic changes. In particular, patterns methylation of cytosines at the 5-position (5mC in the context of CpGs are frequently altered in tumors. Recent evidence suggests that 5mC can get converted to 5-hydroxylmethylcytosine (5hmC in an enzymatic process involving ten eleven translocation (TET protein family members, and this process appears to be important in facilitating plasticity of cytosine methylation. Here we evaluated the global levels of 5hmC using a validated immunohistochemical staining method in a large series of clear cell renal cell carcinoma (n = 111, urothelial cell carcinoma (n = 55 and testicular germ cell tumors (n = 84 and matched adjacent benign tissues. Whereas tumor-adjacent benign tissues were mostly characterized by high levels of 5hmC, renal cell carcinoma and urothelial cell carcinoma showed dramatically reduced staining for 5hmC. 5hmC levels were low in both primary tumors and metastases of clear cell renal cell carcinoma and showed no association with disease outcomes. In normal testis, robust 5hmC staining was only observed in stroma and Sertoli cells. Seminoma showed greatly reduced 5hmC immunolabeling, whereas differentiated teratoma, embryonal and yolk sack tumors exhibited high 5hmC levels. The substantial tumor specific loss of 5hmC, particularly in clear cell renal cell carcinoma and urothelial cell carcinoma, suggests that alterations in pathways involved in establishing and maintaining 5hmC levels might be very common in cancer and could potentially be exploited for diagnosis and treatment.

    Full Text Available The aim of this work was to determine the sugar, organic acid and mineral compositions of the whole fruit and fractions (skin, pulp and seed of the Paulista (Plinia cauliflora and Sabará (Plinia jaboticaba jabuticaba tree genotypes, as well as the oil compositions of their skin and seeds. High levels of sugar, especially fructose, followed by glucose and sucrose, were encountered in the fruit. In the Paulista genotype, higher levels of total and reducing sugars were found in the pulp and skin, which was not observed when comparing the whole fruit of both genotypes. Five organic acids were found in the whole fruit and in the fractions of the two jabuticaba genotypes in quantitative order: citric acid > succinic acid > malic acid > oxalic acid > acetic acid. Potassium was the most abundant mineral found. This fruit was also shown to be rich in magnesium, phosphorus, calcium and copper. The seed oil had nearly the same constitution as the oil extracted from the skin in both genotypes and the major compounds were an unidentified phytosterol, palmitic, linoleic and oleic acids, and squalene.

    This study was conducted to evaluate the efficacy of a scald additive, RP scald, to reduce Salmonella Typhimurium (ST) levels on inoculated poultry carcasses. The RP scald (contains sodium hydroxide) in a 1% solution has a pH of 11.0, which may reduce bacteria levels on carcasses. In this study, 600 broilers (Ross 708 straight run, 6 wk of age) with 300 broilers in each of 2 experimental trials were divided into 4 scald treatments (inoculated with ST) and 2 noninoculated groups. The treatment groups included 4 scald treatments (n = 50 per experimental group per trial): soft scald (SS; 50 degrees C for 90 s), soft scald with 1.0% added RP scald (SSRP), hard scald (56.6 degrees C for 45 s; HS), and hard scald with 1.0% added RP scald. The noninoculated groups (n = 50 per group per trial) are represented by SS0 and HS0. After defeathering, carcass rinses were collected for ST detection. Results indicated that inoculated broilers from hard scald with 1.0% added RP scald had the lowest Salmonella recovery, whereas carcasses from the SS treatment with no RP additive had the highest ST recovery. In trial 1, the SSRP was more effective in reducing ST than HS alone; however, this trend was not consistent. In trial 2, HS alone was more effective in ST reduction than SSRP. Within each scald temperature, the addition of RP scald increased ST reduction; therefore, RP scald may be effective in reducing ST on broiler carcasses in poultry scalder applications, particularly when hard scald temperatures are used.

    Correlating symptoms and physical examination findings with surgical levels based on common imaging results is not reliable. In patients who have no concordance between radiological and clinical symptoms, the surgical levels determined by conventional magnetic resonance imaging (MRI) and neurogenic examination (NE) may lead to a more extensive surgery and significant complications. We aimed to confirm that whether the use of diffusion tensor imaging (DTI) and paraspinal mapping (PM) techniques can further prevent the occurrence of false positives with conventional MRI, distinguish which are clinically relevant from levels of cauda equina and/or nerve root lesions based on MRI, and determine and reduce the decompression levels of lumbar spinal stenosis than MRI + NE, while ensuring or improving surgical outcomes. We compared the data between patients who underwent MRI + (PM or DTI) and patients who underwent conventional MRI + NE to determine levels of decompression for the treatment of lumbar spinal stenosis. Outcome measures were assessed at 2 weeks, 3 months, 6 months, and 12 months postoperatively. One hundred fourteen patients (59 in the control group, 54 in the experimental group) underwent decompression. The levels of decompression determined by MRI + (PM or DTI) in the experimental group were significantly less than that determined by MRI + NE in the control group (p = 0.000). The surgical time, blood loss, and surgical transfusion were significantly less in the experimental group (p = 0.001, p = 0.011, p = 0.001, respectively). There were no differences in improvement of the visual analog scale back and leg pain (VAS-BP, VAS-LP) scores and Oswestry Disability Index (ODI) scores at 2 weeks, 3 months, 6 months, and 12 months after operation between the experimental and control groups. MRI + (PM or DTI) showed clear benefits in determining decompression levels of lumbar spinal stenosis than MRI + NE. In patients with lumbar spinal

    The organochlorine pesticide methoxychlor (MXC) is a known endocrine disruptor that affects adult rodent females by causing reduced fertility, persistent estrus, and ovarian atrophy. Since MXC is also known to target antral follicles, the major producer of sex steroids in the ovary, the present study was designed to test the hypothesis that MXC decreases estradiol (E 2 ) levels by altering steroidogenic and metabolic enzymes in the antral follicles. To test this hypothesis, antral follicles were isolated from CD-1 mouse ovaries and cultured with either dimethylsulfoxide (DMSO) or MXC. Follicle growth was measured every 24 h for 96 h. In addition, sex steroid hormone levels were measured using enzyme-linked immunosorbent assays (ELISA) and mRNA expression levels of steroidogenic enzymes as well as the E 2 metabolic enzyme Cyp1b1 were measured using qPCR. The results indicate that MXC decreased E 2 , testosterone, androstenedione, and progesterone (P 4 ) levels compared to DMSO. In addition, MXC decreased expression of aromatase (Cyp19a1), 17β-hydroxysteroid dehydrogenase 1 (Hsd17b1), 17α-hydroxylase/17,20-lyase (Cyp17a1), 3β hydroxysteroid dehydrogenase 1 (Hsd3b1), cholesterol side-chain cleavage (Cyp11a1), steroid acute regulatory protein (Star), and increased expression of Cyp1b1 enzyme levels. Thus, these data suggest that MXC decreases steroidogenic enzyme levels, increases metabolic enzyme expression and this in turn leads to decreased sex steroid hormone levels. - Highlights: → MXC inhibits steroidogenesis → MXC inhibits steroidogenic enzymes → MXC induces metabolic enzymes

    This report presents the results of scoping studies carried out to determine the feasibility of the following candidate options to reduce high-level waste volume: (1) low-fluoride, low-volume glass, (2) glass-ceramic and ceramic, (3) Modified Zirflex, (4) inerts removal by neutralization, and (5) modified Fluorinel processes. The results of the scoping studies show that the glass-ceramic/ceramic waste forms and neutralization process with potential HLW volume reductions ranging from 60 to 80% appear feasible, based on laboratory-scale tests. The presently used Fluorinel process modified by reducing HF usage also appears to be feasible and could result in up to a 10% potential volume reduction. If the current process start-up tests verify the practicality, reduced HF usage will be implemented. The low-volume glass and Modified Zirflex processes may also be feasible, based on laboratory tests, but would require significantly more process development and/or modifications and could result in only a 20 to 30% potential volume reduction. Based on these scoping studies, it is recommended that (1) the glass-ceramic/ceramic and neutralization processes be developed further, (2) reduced HF use for the Modified Fluorinel process be implemented as soon as practical and other options reducing chemical usage for criticality control be evaluated, (3) basic development for the glass process be continued as a back-up technology, and (4) laboratory-scale radioactive fuel dissolution testing for the Modified Zirflex process be completed with further process development discontinued unless needed in the future

    Pinholes or other defect sites in a protective oxide coating provide pathways for atomic oxygen in low Earth orbit to reach underlying material. One concept of enhancing the lifetime of materials in low Earth orbit is to apply a leveling coating to the material prior to applying any reflective and protective coatings. Using a surface tension leveling coating concept, a low viscosity epoxy was applied to the surface of several composite coupons. A protective layer of 1000 A of SiO2 was deposited on top of the leveling coating, and the coupons were exposed to an atomic oxygen environment in a plasma asher. Pinhole populations per unit area were estimated by counting the number of undercut sites observed by scanning electron microscopy. Defect density values of 180,000 defects/sq cm were reduced to about 1000 defects/sq cm as a result of the applied leveling coating. These improvements occur at a mass penalty of about 2.5 mg/sq cm.

    People with autism spectrum disorder (ASD) show superior performance for tasks requiring detail-focused processing. Atypical neural connectivity and reduced interhemispheric communication are posited to underlie this cognitive advantage. Given recent conceptualization of autism as a continuum, we sought to investigate whether people with normal but high levels of autism like traits (AQ) also exhibit reduced hemispheric interaction. Sixty right-handed participants completed the AQ questionnaire (Baron-Cohen, Wheelwright, Skinner, Martin, & Clubley, 2001) and a lateralised letter matching task that assessed unilateral and bilateral performance in response to simple (physical) and complex (identity) matches. Whereas people with low self-rated AQ scores showed a bilateral advantage for the more complex task, indicating normal interhemispheric interaction, people in the high AQ group failed to show a bilateral gain for the computationally demanding stimuli. This finding of disrupted interhemispheric interaction converges with a dimensional conceptualisation of ASD, suggesting that the structural anomalies of ASD extend to non-autistic individuals with high levels of autism traits.

    Background. Transmissible spongiform encephalopathies (TSEs) are a group of fatal neurodegenerative diseases caused by novel infectious agents referred to as prions. Prions appear to be composed primarily, if not exclusively, of a misfolded isoform of the cellular prion protein. TSE infectivity is remarkably stable and can resist many aggressive decontamination procedures, increasing human, livestock and wildlife exposure to TSEs. Findings. We tested the hypothesis that UV-ozone treatment reduces levels of the pathogenic prion protein and inactivates the infectious agent. We found that UV-ozone treatment decreased the carbon and prion protein content in infected brain homogenate to levels undetectable by dry-ashing carbon analysis or immunoblotting, respectively. After 8 weeks of ashing, UV-ozone treatment reduced the infectious titer of treated material by a factor of at least 105. A small amount of infectivity, however, persisted despite UV-ozone treatment. When bound to either montmorillonite clay or quartz surfaces, PrPTSE was still susceptible to degradation by UV-ozone. Conclusion. Our findings strongly suggest that UV-ozone treatment can degrade pathogenic prion protein and inactivate prions, even when the agent is associated with surfaces. Using larger UV-ozone doses or combining UV-ozone treatment with other decontaminant methods may allow the sterilization of TSE-contaminated materials. ?? 2009 Aiken et al; licensee BioMed Central Ltd.

    1. The effect of different levels of dietary iron on phytase activity and its subsequent effect on broiler performance were investigated in a 3 × 2 factorial arrangement. A total of 360 day-old Ross 308 male broiler chicks were distributed to 6 experimental diets, formulated with three levels of Fe (60, 80 and 100 mg/kg) and two levels of phytase (0 and 500 FTU/kg). 2. Phytase supplemented to mid-Fe diets increased feed consumption more than the non-supplemented diet at d 24. From hatch to d 35, Fe × phytase interaction significantly influenced the feed intake (FI), body weight gain (BWG) and feed conversion ratio (FCR). The high-Fe diet supplemented with phytase significantly reduced FI and BWG of broilers than those supplemented with low- or mid-Fe diets. The overall FCR was significantly better in birds fed on the mid-Fe diets with phytase supplementation. 3. A significant improvement in ileal digestibility of N, P, Mg and Fe was observed in birds feed diets containing 60 mg Fe/kg, with significant interaction between Fe and phytase. 4. Phytase improved the bone breaking strength when supplemented to low- or mid-Fe diets, compared to the non-supplemented diets. There was a significant Fe × phytase interaction effect. Tibia Fe content was higher in birds fed on phytase-free diets with high Fe but the reverse was the case when phytase was added and their interaction was significant. High dietary Fe significantly increased the accumulation of Fe in liver. 5. Phytase improved Ca-Mg-ATPase, Ca-ATPase and Mg-ATPase activities in jejunum when supplemented to the diet containing 80 mg Fe/kg. 6. This study indicates that high (100 mg/kg) dietary Fe inhibited phytase efficacy and subsequently reduced the overall performance and nutrient utilisation of broilers.

    The oncoprotein c-Myc is often overexpressed in cancer cells, and the stability of this protein has major significance in deciding the fate of a cell. Thus, targeting c-Myc levels is an attractive approach for developing therapeutic agents for cancer treatment. In this study, we report the anti-cancer activity of the macrocyclic peptides [D-Trp]CJ-15,208 (cyclo[Phe-D-Pro-Phe-D-Trp]) and the natural product CJ-15,208 (cyclo[Phe-D-Pro-Phe-Trp]). [D-Trp]CJ-15,208 reduced c-Myc protein levels in prostate cancer cells and decreased cell proliferation with IC 50 values ranging from 2.0 to 16 µM in multiple PC cell lines. [D-Trp]CJ-15,208 induced early and late apoptosis in PC-3 cells following 48 hours treatment, and growth arrest in the G2 cell cycle phase following both 24 and 48 hours treatment. Down regulation of c-Myc in PC-3 cells resulted in loss of sensitivity to [D-Trp]CJ-15,208 treatment, while overexpression of c-Myc in HEK-293 cells imparted sensitivity of these cells to [D-Trp]CJ-15,208 treatment. This macrocyclic tetrapeptide also regulated PP2A by reducing the levels of its phosphorylated form which regulates the stability of cellular c-Myc protein. Thus [D-Trp]CJ-15,208 represents a new lead compound for the potential development of an effective treatment of prostate cancer.

E-mail klr324@psu.eduUnderstanding and projecting future sea-level changes poses nontrivial challenges. Sea-level changes are driven primarily by changes in the density of seawater as well as changes in the size of glaciers and ice sheets. Previous studies have demonstrated that a key source of uncertainties surrounding sea-level projections is the response of the Antarctic ice sheet to warming temperatures. Here we calibrate a previously published and relatively simple model of the Antarctic ice sheet over a hindcast period from the last interglacial period to the present. We apply and compare a range of (pre-) calibration methods, including a Bayesian approach that accounts for heteroskedasticity. We compare the model hindcasts and projections for different levels of model complexity and calibration methods. We compare the projections with the upper bounds from previous studies and find our projections have a narrower range in 2100. Furthermore we discuss the implications for the design of climate risk management strategies.

    Purpose: While several studies have investigated the tradeoffs between radiation dose and image quality (noise) in CT imaging, the purpose of this study was to take this analysis a step further by investigating the tradeoffs between patient radiation dose (including organ dose) and diagnostic accuracy in diagnosis of appendicitis using CT. Methods: This study was IRB approved and utilized data from 20 patients who underwent clinical CT exams for indications of appendicitis. Medical record review established true diagnosis of appendicitis, with 10 positives and 10 negatives. A validated software tool used raw projection data from each scan to create simulated images at lower dose levels (70%, 50%, 30%, 20% of original). An observer study was performed with 6 radiologists reviewing each case at each dose level in random order over several sessions. Readers assessed image quality and provided confidence in their diagnosis of appendicitis, each on a 5 point scale. Liver doses at each case and each dose level were estimated using Monte Carlo simulation based methods. Results: Overall diagnostic accuracy varies across dose levels: 92%, 93%, 91%, 90% and 90% across the 100%, 70%, 50%, 30% and 20% dose levels respectively. And it is 93%, 95%, 88%, 90% and 90% across the 13.5-22mGy, 9.6-13.5mGy, 6.4-9.6mGy, 4-6.4mGy, and 2-4mGy liver dose ranges respectively. Only 4 out of 600 observations were rated "unacceptable" for image quality. Conclusion: The results from this pilot study indicate that the diagnostic accuracy does not change dramatically even at significantly reduced radiation dose.

    containing up to 30% Ereq sucrose or HFCS, and the conclusions from several meta-analyses suggest that fructose has no specific adverse effects relative to any other carbohydrate. Consumption of excess sugar may also promote the development the development of CVD and T2DM indirectly by causing increased body weight and fat gain, but this is also a topic of controversy. Mechanistically, it is plausible that fructose consumption causes increased energy intake and reduced energy expenditure due to its failure to stimulate leptin production. Functional magnetic resonance imaging of the brain demonstrates that the brain responds differently to fructose or fructose-containing sugars compared with glucose or aspartame. There are epidemiological studies which show sugar consumption is associated with body weight gain, and there are intervention studies in which consumption of ad libitum high sugar diets promoted increased body weight gain compared with consumption of ad libitum low sugar diets. However, there are no studies in which energy intake and weight gain were compared in subjects consuming high or low sugar, blinded, ad libitum diets formulated to ensure both groups consumed a comparable macronutrient distribution and the same amounts of fiber. There is also little data to determine whether the form in which added sugar is consumed, as beverage or as solid food, affects its potential to promote weight gain. It will be very challenging to obtain the funding to conduct the clinical diet studies needed to address these evidence gaps, especially at the levels of added sugar that are commonly consumed. Yet, filling these evidence gaps may be necessary for supporting the policy changes that will help to turn the food environment into one that does not promote the development of obesity and metabolic disease.

    To explore the possible regulatory effect of Pulsatilla decoction on Th17 cells and inflammatory cytokines of vulvovaginal candidiasis (VVC) mice. Seventy-two female Kunming mice were randomly assigned into six groups: a blank control group, a VVC model group, a fluconazole group and three Pulsatilla decoction groups (dose levels: 22.5, 15.0 and 7.5 g/kg, respectively). The VVC mouse models were established by vaginal inoculation with Candida albicans (C. albicans) in female mice in pseudoestrus state caused by estradiol injection. After 7-day treatment on VVC mice, the vaginal C. albicans burden was assessed using dilution spread plate method; the vaginal C. albicans morphology was observed by Gram staining method; the levels of interleukin 6 (IL-6), IL-17, IL-21 and tumor necrosis factor α (TNF-α) in sera were detected by ELISA. The content of the transcription factor retinoid related orphan receptor gamma t (RORγt) in vaginal tissues was detected by immunohistochemistry. The VVC mouse models were successfully developed. After treatment, the vaginal C. albicans burden of the fluconazole group and 22.5 g/kg Pulsatilla decoction group dropped significantly compared with that of the VVC model group. Gram staining showed that the VVC mice had lots of C. albicans hyphae in vaginal discharge, that 7.5 g/kg Pulsatilla decoction group remained the mycelia-phase C. albicans, and that 15.0 g/kg Pulsatilla decoction group had the majority of yeast-phase C. albicans and a few of mycelia-phase, while no hyphae and only very few of yeast-phase C. albicans were observed in 22.5 g/kg Pulsatilla decoction group and fluconazole group. After 7-day treatment, compared with the model group, the levels of IL-6, IL- 17, IL-21 and TNF-α in the sera of the fluconazole group, 15.0 and 22.5 g/kg Pulsatilla decoction groups were reduced significantly and the levels of RORγt in the vaginal tissues of the fluconazole group, 15.0 and 22.5 g/kg Pulsatilla decoction groups also decreased

    Lacosamide, a histone deacetylase (HDAC) inhibitor, has been approved for the treatment of epilepsy. Some HDAC inhibitors have been proven effective for the treatment of memory disorders. The present investigation was designed to evaluate the effect of lacosamide on memory and brain HDAC levels. The effect on memory was evaluated in animals with scopolamine-induced amnesia using the elevated plus maze, object recognition test, and radial arm maze. The levels of acetylcholinesterase and HDAC in the cerebral cortex were evaluated. Lacosamide at doses of 10 and 30mg/kg significantly reduced the transfer latency in the elevated plus maze. Lacosamide at a dose of 30mg/kg significantly increased the time spent with a familiar object in the object recognition test at the 24h interval and decreased the time spent in the baited arm. Moreover, at this dose, the number of errors in the radial arm maze at 3 and 24h intervals was minimized and a reduction in the level of HDAC1, but not acetylcholinesterase, was observed in the cerebral cortex. These effects of lacosamide are equivalent to those of piracetam at a dose of 300mg/kg. These results suggest that lacosamide at a 30mg/kg dose improves disrupted memory, possibly by inhibiting HDAC, and could be used to treat amnesic symptoms of Alzheimer's disease.

    Full Text Available Oxidized LDL (ox-LDL lipoproteins are proposed as important modified particles triggering pro-inflammatory events through receptor-mediated pathways. We evaluated the circulating ox-LDL level on the concept that the chronic immune events may affect ox-LDL clearance as the vessel stenosis develops in coronary arteries. One hundred sixty five subjects underwent coronary angiography and then, subdivided into four subgroups controls (n=85; SVD, 2VD and 3VD (n=80. The serum ox-LDL level and other biochemical parameters were measured using ELISA method and routine laboratory techniques, respectively. The serum ox-LDL level in the control group (4.81±1.41 mU/mg was significantly higher than patients (4.28±1.73 mU/mg, P<0.05. The ox-LDL/LDL ratio was conversely reduced with the extent of stenosis as compared with the controls (P<0.05. Furthermore, no difference was observed in the ox-LDL/LDL ratio between the 2VD and 3VD patients. We suggested the atherosclerosis process increases the total clearing capacities of the circulating ox-LDL particles.

    There is a direct link between a variety of addictions and mood states to which exercise could be relieving. Sugar addiction has been recently counted as another binge/compulsive/addictive eating behavior, differently induced, leading to a high-significant health problem. Regularly exercising at moderate intensity has been shown to efficiently and positively impact upon physiological imbalances caused by several morbid conditions, including affective disorders. Even in a wider set of physchiatric diseases, physical exercise has been prescribed as a complementary therapeutic strategy. A comprehensive literature search was carried out in the Cochrane Library and MEDLINE databases (search terms: sugar addiction, food craving, exercise therapy, training, physical fitness, physical activity, rehabilitation and aerobic). Seeking high-sugar diets, also in a reward- or craving-addiction fashion, can generate drastic metabolic derangements, often interpolated with affective disorders, for which exercise may represent a valuable, universal, non-pharmachological barrier. More research in humans is needed to confirm potential exercise-mechanisms that may break the bond between sugar over-consumption and affective disorders. The purpose of this review is to address the importance of physical exercise in reversing the gloomy scenario of unhealthy diets and sedentary lifestyles in our modern society.

    Full Text Available Abstract Background The objective was to provide a systematic review of the effectiveness of community-level interventions to reduce maternal mortality. Methods We searched published papers using Medline, Embase, Cochrane library, CINAHL, BNI, CAB ABSTRACTS, IBSS, Web of Science, LILACS and African Index Medicus from inception or at least 1982 to June 2006; searched unpublished works using National Research Register website, metaRegister and the WHO International Trial Registry portal. We hand searched major references. Selection criteria were maternity or childbearing age women, comparative study designs with concurrent controls, community-level interventions and maternal death as an outcome. We carried out study selection, data abstraction and quality assessment independently in duplicate. Results We found five cluster randomised controlled trials (RCT and eight cohort studies of community-level interventions. We summarised results as odds ratios (OR and confidence intervals (CI, combined using the Peto method for meta-analysis. Two high quality cluster RCTs, aimed at improving perinatal care practices, showed a reduction in maternal mortality reaching statistical significance (OR 0.62, 95% CI 0.39 to 0.98. Three equivalence RCTs of minimal goal-oriented versus usual antenatal care showed no difference in maternal mortality (1.09, 95% CI 0.53 to 2.25. The cohort studies were of low quality and did not contribute further evidence. Conclusion Community-level interventions of improved perinatal care practices can bring about a reduction in maternal mortality. This challenges the view that investment in such interventions is not worthwhile. Programmes to improve maternal mortality should be evaluated using randomised controlled techniques to generate further evidence.

    Dissection is a very useful method of learning veterinary anatomy. However, formaldehyde, which is widely used to preserve cadavers, is an irritant, and it has recently been classified as a carcinogen. In 1997, the Instituto Nacional de Seguridad e Higiene en el Trabajo [National Institute of Workplace Security and Hygiene] found that the levels of formaldehyde in our dissection room were above the threshold limit values. Unfortunately, no optimal substitute for formaldehyde is currently available. Therefore, we designed a new ventilation system that combines slow propulsion of fresh air from above the dissection table and rapid aspiration of polluted air from the perimeter. Formaldehyde measurements performed in 2004, after the introduction of this new system into our dissection laboratory, showed a dramatic reduction (about tenfold, or 0.03 ppm). A suitable propelling/aspirating air system successfully reduces the concentration of formaldehyde in the dissection room, significantly improving safety conditions for students, instructors, and technical staff during gross anatomy learning.

    A number of previous studies have identified antigen-presenting cells (APCs) as key targets of Ebola virus (EBOV), but the role of APCs in human Ebola virus disease (EVD) is not known. We have evaluated the phenotype and kinetics of monocytes, neutrophils, and dendritic cells (DCs) in peripheral blood of patients for whom EVD was diagnosed by the European Mobile Laboratory in Guinea. Acute EVD was characterized by reduced levels of circulating nonclassical CD16 + monocytes with a poor activation profile. In survivors, CD16 + monocytes were activated during recovery, coincident with viral clearance, suggesting an important role of this cell subset in EVD pathophysiology. © The Author 2016.

  10. Dual Z-Source Inverter With Three-Level Reduced Common-Mode Switching

    DEFF Research Database (Denmark)

    Gao, Feng; Loh, Poh Chiang; Blaabjerg, Frede

    2007-01-01

    This paper presents the design of a dual Z-source inverter that can be used with either a single dc source or two isolated dc sources. Unlike traditional inverters, the integration of a properly designed Z-source network and semiconductor switches to the proposed dual inverter allows buck......-boost power conversion to be performed over a wide modulation range, with three-level output waveforms generated. The connection of an additional transformer to the inverter ac output also allows all generic wye-or delta-connected loads with three-wire or four-wire configuration to be supplied by the inverter....... Modulationwise, the dual inverter can be controlled using a carefully designed carrier-based pulsewidth-modulation (PWM) scheme that will always ensure balanced voltage boosting of the Z-source network while simultaneously achieving reduced common-mode switching. Because of the omission of dead-time delays...

  11. Using electrochemical separation to reduce the volume of high-level nuclear waste

    International Nuclear Information System (INIS)

    Slater, S.A.; Gay, E.C.

    1998-01-01

    Argonne National Laboratory (ANL) has developed an electrochemical separation technique called electrorefining that will treat a variety of metallic spent nuclear fuel and reduce the volume of high-level nuclear waste that requires disposal. As part of that effort, ANL has developed a high throughput electrorefiner (HTER) that has a transport rate approximately three times faster than electrorefiners previously developed at ANL. This higher rate is due to the higher electrode surface area, a shorter transport path, and more efficient mixing, which leads to smaller boundary layers about the electrodes. This higher throughput makes electrorefining an attractive option in treating Department of Energy spent nuclear fuels. Experiments have been done to characterize the HTER, and a simulant metallic fuel has been successfully treated. The HTER design and experimental results is discussed

    2005-01-01

    Using Model 1027 continuous radon monitor, a test of reducing radon level by ventilation in underground space was done. Four different types of ventilation, i.e. by air pump (P), by air intake blower (B), by air pump and air intake blower simultaneously (PBS), and by air pump and air intake blower in turn (PBT), were examined. The authors found that efficiency of PBS is the highest among these ventilation type. Having ventilated the underground space with PBS for 1, 2 or 3 hours in three different days, and having observed the radon concentration change in the following 24 hours, the authors can conclude that it is safe for people to stay there during the eight working hours if the underground space is ventilated for 2 hours everyday in the morning.

    A system using optical two-level orthogonal-frequency-division-multiplexing (OFDM) - amplitude-shift-keying (ASK) modulation is proposed and demonstrated to reduce the processing latency for the optical mobile fronthaul networks. At the proposed remote-radio-head (RRH), the high data rate OFDM signal does not need to be processed, but is directly launched into a high speed photodiode (HSPD) and subsequently emitted by an antenna. Only a low bandwidth PD is needed to recover the low data rate ASK control signal. Hence, it is simple and provides low-latency. Furthermore, transporting the proposed system over the already deployed optical-distribution-networks (ODNs) of passive-optical-networks (PONs) is also demonstrated with 256 ODN split-ratios.

    Full Text Available The use of other inducers as substitutes for pectin was studied aiming to reduce the production costs of pectic enzymes. The effects of sugar-cane juice on the production of pectin lyase (PL and polygalacturonase (PG by Penicillium griseoroseum were investigated. The fungus was cultured in a mineral medium (pH 6.3 in a rotary shaker (150 rpm for 48 h at 25oC. Culture media were supplemented with yeast extract and sucrose or sugar-cane juice. Sugar-cane juice added singly to the medium promoted higher PL activity and mycelial dry weight when compared to pectin and the use of sugar-cane juice and yeast extract yielded levels of PG activity that were similar to those obtained with sucrose-yeast extract or pectin. The results indicated that, even at low concentrations, sugar-cane juice was capable of inducing pectin lyase and polygalacturonase with no cellulase activity in P. griseoroseum.

  18. Reducing the likelihood of future human activities that could affect geologic high-level waste repositories

    International Nuclear Information System (INIS)

    1984-05-01

    The disposal of radioactive wastes in deep geologic formations provides a means of isolating the waste from people until the radioactivity has decayed to safe levels. However, isolating people from the wastes is a different problem, since we do not know what the future condition of society will be. The Human Interference Task Force was convened by the US Department of Energy to determine whether reasonable means exist (or could be developed) to reduce the likelihood of future human unintentionally intruding on radioactive waste isolation systems. The task force concluded that significant reductions in the likelihood of human interference could be achieved, for perhaps thousands of years into the future, if appropriate steps are taken to communicate the existence of the repository. Consequently, for two years the task force directed most of its study toward the area of long-term communication. Methods are discussed for achieving long-term communication by using permanent markers and widely disseminated records, with various steps taken to provide multiple levels of protection against loss, destruction, and major language/societal changes. Also developed is the concept of a universal symbol to denote Caution - Biohazardous Waste Buried Here. If used for the thousands of non-radioactive biohazardous waste sites in this country alone, a symbol could transcend generations and language changes, thereby vastly improving the likelihood of successful isolation of all buried biohazardous wastes

    Sibutramine is a selective inhibitor of the reuptake of monoamines. Plasma levels of brain natriuretic peptide (BNP) appear to be inversely associated with body mass index (BMI) in subjects with and without heart failure for reasons that remain unexplained. The aim of this study was to investigate the possible influence of sibutramine treatment on BNP levels in severely obese patients. Fifty-two severely obese female patients with BMI > 40 kg/m(2) were included to this study. The women were recommended to follow a weight-reducing daily diet of 25 kcal/kg of ideal body weight. During the treatment period, all patients were to receive 15 mg of sibutramine once a day. Blood chemistry tests were performed before the onset of the medication and after 12 weeks of treatment. None of the subjects was withdrawn from the study because of the adverse effects of sibutramine. Body weight (108.8 +/- 13.3 kg vs. 101.7 +/- 15.6 kg, p sibutramine treatment. Total cholesterol (5.19 +/- 0.90 mmol/l vs. 4.82 +/- 1.05 mmol/l respectively; p sibutramine treatment. Further randomised studies are needed to be conducted to clarify the relationship between sibutramine and BNP.

    In the reward circuitry of the brain, alpha-7-nicotinic acetylcholine receptors (α7nAChRs) modulate effects of delta-9-tetrahydrocannabinol (THC), marijuana’s main psychoactive ingredient. Kynurenic acid (KYNA) is an endogenous negative allosteric modulator of α7nAChRs. Here we report that the kynurenine 3-monooxygenase (KMO) inhibitor Ro 61-8048 increases brain KYNA levels and attenuates cannabinoid-induced increases in extracellular dopamine in reward-related brain areas. In the self-administration model of drug abuse, Ro 61-8048 reduced the rewarding effects of THC and the synthetic cannabinoid WIN 55,212-2 in squirrel monkeys and rats, respectively, and it also prevented relapse to drug-seeking induced by re-exposure to cannabinoids or cannabinoid-associated cues. The effects of enhancing endogenous KYNA levels with Ro 61-8048 were prevented by positive allosteric modulators of α7nAChRs. Despite a clear need, there are currently no medications approved for treatment of marijuana dependence. Modulation of KYNA provides a novel pharmacological strategy for achieving abstinence from marijuana and preventing relapse. PMID:24121737

    2010-09-01

    Full Text Available Abstract Background Stearoyl-CoA desaturase 1 (SCD1 is an ER resident enzyme introducing a double-bond in saturated fatty acids. Global knockout of SCD1 in mouse increases fatty acid oxidation and insulin sensitivity which makes the animal resistant to diet-induced obesity. Inhibition of SCD1 has therefore been proposed as a potential therapy of the metabolic syndrome. Much of the work has focused on insulin target tissue and very little is known about how reduced levels of SCD1 would affect the insulin-producing β-cell, however. The aim of the present study was therefore to investigate how reduced levels of SCD1 affect the β-cell. Results Insulin-secreting MIN6 cells with reduced levels of SCD1 were established by siRNA mediated knockdown. When fatty acid oxidation was measured, no difference between cells with reduced levels of SCD1 and mock-transfected cells were found. Also, reducing levels of SCD1 did not affect insulin secretion in response to glucose. To investigate how SCD1 knockdown affected cellular mechanisms, differentially regulated proteins were identified by a proteomic approach. Cells with reduced levels of SCD1 had higher levels of ER chaperones and components of the proteasome. The higher amounts did not protect the β-cell from palmitate-induced ER stress and apoptosis. Instead, rise in levels of p-eIF2α and CHOP after palmitate exposure was 2-fold higher in cells with reduced levels of SCD1 compared to mock-transfected cells. Accordingly, apoptosis rose to higher levels after exposure to palmitate in cells with reduced levels of SCD1 compared to mock-transfected cells. Conclusions In conclusion, reduced levels of SCD1 augment palmitate-induced ER stress and apoptosis in the β-cell, which is an important caveat when considering targeting this enzyme as a treatment of the metabolic syndrome.

    were seen in the underweight and wasting levels. However, significant improvements in the median height-for-age z-score (HAZ) were found in levels of stunting on Day-1 (-2.37 SD, n = 381) vs. 6-month follow-up (-1.99 SD, n = 314)(Z = -7.683, p<0.0001). Unfortunately, there were significant increases in the levels of stunting on Day-1 (-2.37 SD, n = 381) vs. 1-Year follow-up (-2.70 SD, n = 242)(Z = -2.21, p = 0.027). CONCLUSION: An integrated blanket supplementary feeding program could possibly reduce levels of stunting in just 6-months, but continued monitoring is required of the children even if the children are discharged from the program to ensure their rehabilitation is sustained at home. The increase in levels of stunting at 1-Year follow-up may have been due to the fact that many of the rehabilitated children were discharged and not followed up for the study. Thus, further research is needed to assess the effects of integrated blanket supplementary feeding programs on reducing levels of stunting. (author)

    To assess the effects of different levels of spontaneous breathing during biphasic positive airway pressure/airway pressure release ventilation on lung function and injury in an experimental model of moderate acute respiratory distress syndrome. Multiple-arm randomized experimental study. University hospital research facility. Thirty-six juvenile pigs. Pigs were anesthetized, intubated, and mechanically ventilated. Moderate acute respiratory distress syndrome was induced by repetitive saline lung lavage. Biphasic positive airway pressure/airway pressure release ventilation was conducted using the airway pressure release ventilation mode with an inspiratory/expiratory ratio of 1:1. Animals were randomly assigned to one of four levels of spontaneous breath in total minute ventilation (n = 9 per group, 6 hr each): 1) biphasic positive airway pressure/airway pressure release ventilation, 0%; 2) biphasic positive airway pressure/airway pressure release ventilation, > 0-30%; 3) biphasic positive airway pressure/airway pressure release ventilation, > 30-60%, and 4) biphasic positive airway pressure/airway pressure release ventilation, > 60%. The inspiratory effort measured by the esophageal pressure time product increased proportionally to the amount of spontaneous breath and was accompanied by improvements in oxygenation and respiratory system elastance. Compared with biphasic positive airway pressure/airway pressure release ventilation of 0%, biphasic positive airway pressure/airway pressure release ventilation more than 60% resulted in lowest venous admixture, as well as peak and mean airway and transpulmonary pressures, redistributed ventilation to dependent lung regions, reduced the cumulative diffuse alveolar damage score across lungs (median [interquartile range], 11 [3-40] vs 18 [2-69]; p ventilation more than 0-30% and more than 30-60% showed a less consistent pattern of improvement in lung function, inflammation, and damage compared with biphasic positive airway

    Full Text Available Background: The outcome of patients with spontaneous supratentorial intracerebral hemorrhage (SSICH is unsatisfactory. Inflammatory response secondary to brain injury as well as those resulted from surgical procedure were considered responsible of this outcome. This study was intended to elucidate the anti-inflammatory activity of tigecycline by measuring TNF-α level and its neuroprotective effect as represented by inhospital mortality rate.Methods: Patients with SSICH who were prepared for hematoma evacuation were randomized to receive either tigecycline (n=35 or fosfomycine (n=37 as prophylactic antibiotic. TNF-α level was measured in all subjects before surgery and postoperatively on day-1 and day-7. A repeated brain CT Scan was performed on postoperative day-7. The Glasgow outcome scale (GOS and length of stay (LOS were recorded at the time of hospital discharge. Data were analyzed using Mann-Whitney and Chi square test. Relative clinical effectiveness was measured by calculating the number needed to treat (NNT.Results: There was a significant difference regarding the proportion of subject who had  reduced TNF-α level on postoperative day-7 between the groups receiving tigecycline and fosfomycine (62% vs 29%, p=0.022. Decrease brain edema on CT control (86% vs 80%, p=0.580. Tigecycline administration showed a tendency of better clinical effectiveness in lowering inhospital mortality (17% vs 35%; p=0.083; OR=0.49; NNT=5 and worse clinical outcome / GOS ≤ 2 (20% vs 38% ; p=0.096; OR=0.41; NNT=6.

    Despite at least 40 years of promising empirical performance, very few clinical natural language processing (NLP) or information extraction systems currently contribute to medical science or care. The authors address this gap by reducing the need for custom software and rules development with a graphical user interface-driven, highly generalizable approach to concept-level retrieval. A 'learn by example' approach combines features derived from open-source NLP pipelines with open-source machine learning classifiers to automatically and iteratively evaluate top-performing configurations. The Fourth i2b2/VA Shared Task Challenge's concept extraction task provided the data sets and metrics used to evaluate performance. Top F-measure scores for each of the tasks were medical problems (0.83), treatments (0.82), and tests (0.83). Recall lagged precision in all experiments. Precision was near or above 0.90 in all tasks. Discussion With no customization for the tasks and less than 5 min of end-user time to configure and launch each experiment, the average F-measure was 0.83, one point behind the mean F-measure of the 22 entrants in the competition. Strong precision scores indicate the potential of applying the approach for more specific clinical information extraction tasks. There was not one best configuration, supporting an iterative approach to model creation. Acceptable levels of performance can be achieved using fully automated and generalizable approaches to concept-level information extraction. The described implementation and related documentation is available for download.

    We generated transgenic tobacco plants with high levels of fructose-1,6-bisphosphatase expressing cyanobacterialfructose-1,6-/sedoheptulose-1,7-bisphosphatase in the cytosol. At ambient CO(2) levels (360 ppm), growth, photosynthetic activity, and fresh weight were unchanged but the sucrose/hexose/starch ratio was slightly altered in the transgenic plants compared with wild-type plants. At elevated CO(2) levels (1200 ppm), lateral shoot, leaf number, and fresh weight were significantly increased in the transgenic plants. Photosynthetic activity was also increased. Hexose accumulated in the upper leaves in the wild-type plants, while sucrose and starch accumulated in the lower leaves and lateral shoots in the transgenic plants. These findings suggest that cytosolic fructose-1,6-bisphosphatase contributes to the efficient conversion of hexose into sucrose, and that the change in carbon partitioning affects photosynthetic capacity and morphogenesis at elevated CO(2) levels.

    Dramatic increase in NaCl consumption lead to sodium intake beyond health guidelines. KCl substitution helps reduce sodium intake but results in a bitter-metallic off-taste. Two disaccharides, trehalose and sucrose, were tested in order to untangle the chemical (increase in effective concentration of KCl due to sugar addition) from the sensory effects. The bitter-metallic taste of KCl was reduced by these sugars, while saltiness was enhanced or unaltered. The perceived sweetness of sugar, regardless of its type and concentration, was an important factor in KCl taste modulation. Though KCl was previously shown to increase the chemical activity of trehalose but not of sucrose, we found that it suppressed the perceived sweetness of both sugars. Therefore, sensory integration was the dominant factor in the tested KCl-sugar combinations. Copyright © 2018 Elsevier Ltd. All rights reserved.

    The study aimed to determine the opinions and attitudes of a university population regarding the regulation of sugar-sweetened beverages in a university setting, primarily looking at differences in opinion between younger adults (under 30 years of age) and older adults (30 years of age or older). An online survey was conducted at an Australian university in April-May 2016 using a convenience sample of students and staff between the ages of 16 and 84 years. The survey included questions about consumption of sugar-sweetened beverages and level of agreement and support of proposed sugar-sweetened beverage interventions. Quantitative response data and qualitative open-ended response data were analysed. Nine hundred thirteen responses from students and staff were analysed. In this population, consumption of sugar-sweetened beverages was low and awareness of the health risks of sugar-sweetened beverages was high. Overall, the surveyed population indicated more support for interventions that require higher levels of personal responsibility. The population did support some environment-centred, population-based interventions, such as increasing access to drinking water and reducing the price of healthier beverage alternatives. However there was less support for more restrictive interventions such as removing sugar-sweetened beverages from sale. Young adults tended to be less supportive of most interventions than older adults. These findings indicate there is some support for environment-centred, population-based approaches to reduce the availability and appeal of sugar-sweetened beverages in an adult environment such as a university setting. However these results suggest that public health may need to focus less on educating populations about the harms associated with sugar-sweetened beverages. Instead, there should be greater emphasis on explaining to populations and communities why environment-centred approaches relating to the sale and promotion of sugar

    Full Text Available Sugars and sugar-alcohols are demonstrated to be important constituents of the ambient aerosol water-soluble organic carbon fraction, and to be tracers for primary biological aerosol particles (PBAP. In the present study, levels of four sugars (fructose, glucose, sucrose, trehalose and three sugar-alcohols (arabitol, inositol, mannitol in ambient aerosols have been quantified using a novel HPLC/HRMS-TOF (High Performance Liquid Chromatography in combination with High Resolution Mass Spectrometry – Time of Flight method to assess the contribution of PBAP to PM>sub>10 and PM2.5. Samples were collected at four sites in Norway at different times of the year in order to reflect the various contributing sources and the spatial and seasonal variation of the selected compounds.

    Sugars and sugar-alcohols were present at all sites investigated, underlining the ubiquity of these highly polar organic compounds. The highest concentrations were reported for sucrose, reaching a maximum concentration of 320 ng m−3 in PM10 and 55 ng m−3 in PM2.5. The mean concentration of sucrose was up to 10 times higher than fructose, glucose and the dimeric sugar trehalose. The mean concentrations of the sugar-alcohols were typically lower, or equal, to that of the monomeric sugars and trehalose. Peak concentrations of arabitol and mannitol did not exceed 30 ng m−3 in PM10, and for PM2.5 all concentrations were below 6 ng m−3.

    Sugars and sugar-alcohols were associated primarily with coarse aerosols except during wintertime at the suburban site in Elverum, where a shift towards sub micron aerosols was observed. It is proposed that this shift was due to the intensive use of wood burning for residential heating at this site during winter, confirmed by high concurrent concentrations of levoglucosan. Elevated concentrations of sugars in PM2

    To screen for and characterize lactic acid bacteria strains with the ability to produce fermented milk and reduce cholesterol levels. The strains were isolated from traditional fermented milk in China. In vitro and in vivo evaluation of cholesterol-reduction were used to identify and verify strains of interest. Characteristics were analyzed using spectrophotometry and plate counting assays. The isolate HLX37 consistently produced fermented milk with strong cholesterol-reducing properties was identified as Lactobacillus plantarum (accession number: KR105940) and was thus selected for further study. The cholesterol reduction by strain HLX37 was 45.84%. The isolates were acid-tolerant at pH 2.5 and bile-tolerant at 0.5% (w/v) in simulated gastric juice (pH 2.5) for 2h and in simulated intestinal fluid (pH 8.0) for 3h. The auto-aggregation rate increased to 87.74% after 24h, while the co-aggregation with Escherichia coli DH5 was 27.76%. Strain HLX37 was intrinsically resistant to antibiotics such as penicillin, tobramycin, kanamycin, streptomycin, vancomycin and amikacin. Compared with rats in the model hyperlipidemia group, the total cholesterol content in the serum and the liver as well as the atherogenic index of rats in the viable fermented milk group significantly decreased by 23.33%, 32.37% and 40.23%, respectively. Fewer fat vacuoles and other lesions in liver tissue were present in both the inactivated and viable fermented milk groups compared to the model group. These studies indicate that strain HLX37 of L. plantarum demonstrates probiotic potential, potential for use as a candidate for commercial use for promoting health.

    Do phthalates create a male reproductive hormone imbalance by down-regulating the secretion of testosterone and insulin-like factor 3 (INSL3)? Our study suggests that exposure to phthalates is related to a reduction in the secretion of testosterone and INSL3 in adult males. There is evidence that exposure to phthalates, an abundant group of industrial plasticizers, negatively affects testosterone biosynthesis, but little is known about the mechanism in men. The hypothesis that exposure to phthalates reduces the levels of testosterone and INSL3, a marker of Leydig cell function, is underexplored. This case-control study of 176 men ran from 2010 to 2012. Infertile men were recruited through infertility clinics in Taiwan, fertile men were recruited from childbirth preparation classes and all were categorized based on the World Health Organization definition of infertility and by the diagnoses of obstetricians. Urinary concentrations of 11 phthalate metabolites were measured, along with serum levels of FSH, LH, total testosterone (TT), estradiol, sex hormone-binding globulin and Inhibin B. Androgen status indices including free testosterone (fT) and the free androgen index (FAI) were calculated. The circulating INSL3 level was evaluated using a radioimmunoassay. Non-parametric analyses, trend tests and linear regression models were used. Urinary mono-n-butyl phthalate (MnBP), mono-(2-ethylhexyl) phthalate (MEHP) and mono-2-ethyl-5-carboxypentyl phthalate were significantly higher in infertile than in fertile men. Serum Inhibin B, the Inhibin B : FSH ratio, the TT : LH ratio and INSL3 were significantly lower in infertile men. In multiple regression models controlled for potential confounders, there is an inverse association between urinary levels of mono-methyl phthalate (MMP), mono-iso-butyl phthalate (MiBP), MEHP, MEHP% and serum TT (P = 0.001, 0.007, 0.042 and 0.012, respectively). The inverse associations were also found between urinary levels of MiBP, monobenzyl

  17. The Evidence for Saturated Fat and for Sugar Related to Coronary Heart Disease.

    Dietary guidelines continue to recommend restricting intake of saturated fats. This recommendation follows largely from the observation that saturated fats can raise levels of total serum cholesterol (TC), thereby putatively increasing the risk of atherosclerotic coronary heart disease (CHD). However, TC is only modestly associated with CHD, and more important than the total level of cholesterol in the blood may be the number and size of low-density lipoprotein (LDL) particles that contain it. As for saturated fats, these fats are a diverse class of compounds; different fats may have different effects on LDL and on broader CHD risk based on the specific saturated fatty acids (SFAs) they contain. Importantly, though, people eat foods, not isolated fatty acids. Some food sources of SFAs may pose no risk for CHD or possibly even be protective. Advice to reduce saturated fat in the diet without regard to nuances about LDL, SFAs, or dietary sources could actually increase people's risk of CHD. When saturated fats are replaced with refined carbohydrates, and specifically with added sugars (like sucrose or high fructose corn syrup), the end result is not favorable for heart health. Such replacement leads to changes in LDL, high-density lipoprotein (HDL), and triglycerides that may increase the risk of CHD. Additionally, diets high in sugar may induce many other abnormalities associated with elevated CHD risk, including elevated levels of glucose, insulin, and uric acid, impaired glucose tolerance, insulin and leptin resistance, non-alcoholic fatty liver disease, and altered platelet function. A diet high in added sugars has been found to cause a 3-fold increased risk of death due to cardiovascular disease, but sugars, like saturated fats, are a diverse class of compounds. The monosaccharide, fructose, and fructose-containing sweeteners (e.g., sucrose) produce greater degrees of metabolic abnormalities than does glucose (either isolated as a monomer, or in chains as starch

    Full Text Available     Loss of sugars contributes to accelerate postharvest senescence of broccoli. Several treatments have been developed to delay senescence, but in many cases their effects on sugar metabolism were not analyzed. We studied the effect of harvest at different times of day (08:00, 13:00 and 18:00 h and of several postharvest treatments as heat treatment (HT, modified atmosphere (MA and 1-methylcylcopropene (1-MCP on sugar levels and activities of enzymes related to sucrose and starch degradation. Harvesting at the end of day delayed the loss of chlorophylls and caused the lowest decrement in sugars, although no differences in invertase, sucrose synthase and β-amylase activities were detected among samples. Treatments of MA and 1-MCP caused a lower loss of glucose and fructose, while HT caused a lower decrement of sucrose. Treated samples maintained higher levels of chlorophylls. The treatments reduced the activity of invertase and sucrose synthase and induced higher levels of β-amylase activity. Harvesting at the end of day and performing simultaneously a MA treatment could be a good combination to maintain the green color of the inflorescence and sugar levels during postharvest of broccoli.

    Nationwide, emergency response systems depend on 9-1-1 telecommunicators to prioritize, triage, and dispatch assistance to those in distress. 9-1-1 call center telecommunicators (TCs) are challenged by acute and chronic workplace stressors: tense interactions with citizen callers in crisis; overtime; shift-work; ever-changing technologies; and negative work culture, including co-worker conflict. This workforce is also subject to routine exposures to secondary traumatization while handling calls involving emergency situations and while making time urgent, high stake decisions over the phone. Our study aims to test the effectiveness of a multi-part intervention to reduce stress in 9-1-1 TCs through an online mindfulness training and a toolkit containing workplace stressor reduction resources. The study employs a randomized controlled trial design with three data collection points. The multi-part intervention includes an individual-level online mindfulness training and a call center-level organizational stress reduction toolkit. 160 TCs will be recruited from 9-1-1 call centers, complete a baseline survey at enrollment, and are randomly assigned to an intervention or a control group. Intervention group participants will start a 7-week online mindfulness training developed in-house and tailored to 9-1-1 TCs and their call center environment; control participants will be "waitlisted" and start the training after the study period ends. Following the intervention group's completion of the mindfulness training, all participants complete a second survey. Next, the online toolkit with call-center wide stress reduction resources is made available to managers of all participating call centers. After 3 months, a third survey will be completed by all participants. The primary outcome is 9-1-1 TCs' self-reported symptoms of stress at three time points as measured by the C-SOSI (Calgary Symptoms of Stress Inventory). Secondary outcomes will include: perceptions of social work

    Full Text Available Cooking of massecuites has been study in the connection with different particle size distribution of white sugar. During the crystallization is possible to operate with parameters which have influence on particle size of white sugar. Dry matter of juice in crystallizer, volume of the standard syrup in crystallizer and heating curve of crystallization process are constant parameters in this process. Quantity of slurry (seed magma crystallizate and volume of slurry massecuite are parameters which can be changed for control the particle size distribution of white sugar. Five variants of viable parameters have been trying for obtain ideal particle size distribution of white sugar. As a best has been evaluated variant with 1100 cm3 of slurry and 20 % of volume of slurry massecuite in crystallizer. This variant has had the crystals proportions captured by the sieves between 1.00 and 0.40 mm with minimal differences in weight. More results have been related to reduction of losses of sugar in molasses with the right setting for the line of cooling crystallization process. The looses of sugar can be reduced by adding two coolers in the end of cooling crystalization process what will decrease a temperature to 40 ° C. This temperature will lead to more efficient crystallization in the cooling crystallization process.doi:10.5219/122

    Immune and inflammatory pathways play important roles in the pathogenesis of metabolic disorders. This study investigated the role of toll-like receptor 4 (TLR4) in orosensory detection of dietary lipids and sugars. Taste preferences of TLR4 knockout (KO) and wild-type (WT) male mice under a standard and a high-fat, high-sugar diet were assessed with two-bottle tests. Gene expression of taste signaling molecules was analyzed in the tongue epithelium. The role of TLR4 in food intake and weight gain was investigated in TLR4 KO and WT mice fed a high-fat and high-sugar diet for 12 weeks. Compared to WT mice, TLR4 KO mice showed reduced preference for lipids, sugars, and umami in a two-bottle preference test. The altered taste perception was associated with decreased levels of key taste regulatory molecules in the tongue epithelium. TLR4 KO mice on a high-fat and high-sugar diet consumed less food and drink, resulting in diminished weight gain. TLR4 signaling promotes ingestion of sugar and fat by a mechanism involving increased preference for such obesogenic foods. © 2017 The Obesity Society.

  2. Communication impairments in mice lacking Shank1: reduced levels of ultrasonic vocalizations and scent marking behavior.

    Markus Wöhr

    Full Text Available Autism is a neurodevelopmental disorder with a strong genetic component. Core symptoms are abnormal reciprocal social interactions, qualitative impairments in communication, and repetitive and stereotyped patterns of behavior with restricted interests. Candidate genes for autism include the SHANK gene family, as mutations in SHANK2 and SHANK3 have been detected in several autistic individuals. SHANK genes code for a family of scaffolding proteins located in the postsynaptic density of excitatory synapses. To test the hypothesis that a mutation in SHANK1 contributes to the symptoms of autism, we evaluated Shank1(-/- null mutant mice for behavioral phenotypes with relevance to autism, focusing on social communication. Ultrasonic vocalizations and the deposition of scent marks appear to be two major modes of mouse communication. Our findings revealed evidence for low levels of ultrasonic vocalizations and scent marks in Shank1(-/- mice as compared to wildtype Shank1(+/+ littermate controls. Shank1(-/- pups emitted fewer vocalizations than Shank1(+/+ pups when isolated from mother and littermates. In adulthood, genotype affected scent marking behavior in the presence of female urinary pheromones. Adult Shank1(-/- males deposited fewer scent marks in proximity to female urine than Shank1(+/+ males. Call emission in response to female urinary pheromones also differed between genotypes. Shank1(+/+ mice changed their calling pattern dependent on previous female interactions, while Shank1(-/- mice were unaffected, indicating a failure of Shank1(-/- males to learn from a social experience. The reduced levels of ultrasonic vocalizations and scent marking behavior in Shank1(-/- mice are consistent with a phenotype relevant to social communication deficits in autism.

Core symptoms are abnormal reciprocal social interactions, qualitative impairments in communication, and repetitive and stereotyped patterns of behavior with restricted interests. Candidate genes for autism include the SHANK gene family, as mutations in SHANK2 and SHANK3 have been detected in several autistic individuals. SHANK genes code for a family of scaffolding proteins located in the postsynaptic density of excitatory synapses.

Ultrasonic vocalizations and the deposition of scent marks appear to be two major modes of mouse communication. Our findings revealed evidence for low levels of ultrasonic vocalizations and scent marks in Shank1 −/− mice as compared to wildtype Shank1 +/+ littermate controls. Shank1 −/− pups emitted fewer vocalizations than Shank1+/+ pups when isolated from mother and littermates. In adulthood, genotype affected scent marking behavior in the presence of female urinary pheromones. Adult Shank1 −/− males deposited fewer scent marks in proximity to female urine than Shank1+/+ males. Call emission in response to female urinary pheromones also differed between genotypes. Shank1+/+ mice changed their calling pattern dependent on previous female interactions, while Shank1 −/− mice were unaffected, indicating a failure of Shank1 −/− males to learn from a social experience. The reduced levels of ultrasonic vocalizations and scent marking behavior in Shank1 −/− mice are consistent with a phenotype relevant to social communication deficits in autism. PMID:21695253

    There is considerable political and public awareness of new recommendations to reduce sugars and sugar-sweetened beverages in our diets. It is therefore timely to review the most recent changes in guidelines, with a focus on evidence for metabolic health, recent research in the area and gaps in our knowledge. Sufficient evidence links a high intake of sugar to dental caries and obesity, and high intakes of sugar-sweetened beverages in particular to increased risk of type 2 diabetes. This has led to the updating of dietary recommendations related to added sugars in the diet. The effects of specific sugars at usual intakes as part of an isoenergetic diet are less clear. The glycaemic response to food is complex and mediated by many factors, but sugar intake is not necessarily the major component. There are many challenges faced by healthcare professionals and government bodies in order to improve the health of individuals and nations through evidence-based diets. Sufficiently powered long-term mechanistic studies are still required to provide evidence for the effects of reducing dietary sugars on metabolic health. However, there are many challenges for research scientists in the implementation of these studies.

    Zolpidem is a short-acting imidazopyridine hypnotic that binds at the benzodiazepine binding site on specific GABA(A) receptors to enhance fast inhibitory neurotransmission. The behavioral and receptor pharmacology of zolpidem has been studied extensively, but little is known about its neuronal substrates in vivo. In the present within-subject, double-blind, and placebo-controlled study, blood oxygen level-dependent functional magnetic resonance imaging (BOLD fMRI) at 3 Tesla was used to assess the effects of zolpidem within the brain. Healthy participants (n=12) were scanned 60 min after acute oral administration of zolpidem (0, 5, 10, or 20mg), and changes in BOLD signal were measured in the visual cortex during presentation of a flashing checkerboard. Heart rate and oxygen saturation were monitored continuously throughout the session. Zolpidem (10 and 20mg) reduced the robust visual system activation produced by presentation of this stimulus, but had no effects on physiological activity during the fMRI scan. Zolpidem's modulation of the BOLD signal within the visual cortex is consistent with the abundant distribution of GABA(A) receptors localized in this region, as well as previous studies showing a relationship between increased GABA-mediated neuronal inhibition and a reduction in BOLD activation.

    Full Text Available Negative emotional responses to the daily life stresses have cumulative effects which, in turn, impose wide-ranging negative constraints on emotional well being and neurocognitive performance (Kalueff et al, 2007, Charles et al, 2013, Nadler et al, 2010. Crucial cognitive functions such as memory and problem solving, as well more short term emotional responses (e.g., anticipation of- and response to- monetary rewards or losses are influenced by mood. The negative impact of these behavioural responses is felt at the individual level, but it also imposes major economic burden on modern healthcare systems. Although much research have been undertaken to understand the underlying mechanisms of depressed mood and design efficient treatment pathways, comparatively little was done to characterize mood modulations that remain within the boundaries of a healthy mental functioning. In one placebo-controlled experiments, we applied daily prefrontal transcranial Direct Current Stimulation (tDCS at five points in time, and found reliable improvements on self-reported mood evaluation. We replicated this finding in an independent double-blinded placebo-controlled experiment and showed that stimulation over a shorter period of time (3 days is sufficient to create detectable mood improvements. Taken together, our data show that repeated bilateral prefrontal tDCS can reduce psychological distress in nondepressed individuals.

    Concentrating solar power (CSP) has the potential to become a leading sustainable energy technology for the European electricity system. In order to reach a substantial share in the energy mix, European investment in CSP appears most profitable in North Africa, where solar potential is significantly higher than in southern Europe. As well as sufficient solar irradiance, however, the majority of today's CSP plants also require a considerable amount of water, primarily for cooling purposes. In this paper we examine water usage associated with CSP in North Africa, and the cost penalties associated with technologies that could reduce those needs. We inspect four representative sites to compare the ecological and economical drawbacks from conventional and alternative cooling systems, depending on the local environment, and including an outlook with climate change to the mid-century. Scaling our results up to a regional level indicates that the use of wet cooling technologies would likely be unsustainable. Dry cooling systems, as well as sourcing of alternative water supplies, would allow for sustainable operation. Their cost penalty would be minor compared to the variance in CSP costs due to different average solar irradiance values. - Highlights: → Scaling up CSP with wet cooling from ground water will be unsustainable in North Africa. → Desalination and alternative cooling systems can assure a sustainable water supply. → On large-scale, the cost penalties of alternative cooling technologies appear minor.

    α-Syntrophin is a component of the dystrophin-glycoprotein complex that interacts with various intracellular signaling proteins in muscle cells. The α-syntrophin knock-down C2 cell line (SNKD), established by infecting lentivirus particles with α-syntrophin shRNA, is characterized by a defect in terminal differentiation and increase in cell death. Since myoblast differentiation is accompanied by intensive mitochondrial biogenesis, the generation of intracellular reactive oxygen species (ROS) is also increased during myogenesis. Two-photon microscopy imaging showed that excessive intracellular ROS accumulated during the differentiation of SNKD cells as compared with control cells. The formation of 4-hydroxynonenal adduct, a byproduct of lipid peroxidation during oxidative stress, significantly increased in differentiated SNKD myotubes and was dramatically reduced by epigallocatechin-3-gallate, a well-known ROS scavenger. Among antioxidant enzymes, catalase was significantly decreased during differentiation of SNKD cells without changes at the mRNA level. Of interest was the finding that the degradation of catalase was rescued by MG132, a proteasome inhibitor, in the SNKD cells. This study demonstrates a novel function of α-syntrophin. This protein plays an important role in the regulation of oxidative stress from endogenously generated ROS during myoblast differentiation by modulating the protein stability of catalase. © 2017 Federation of European Biochemical Societies.

    Although the use of prayer as a religious coping strategy is widespread and often claimed to have positive effects on physical disorders including pain, it has never been tested in a controlled experimental setting whether prayer has a pain relieving effect. Religious beliefs and practices are complex phenomena and the use of prayer may be mediated by general psychological factors known to be related to the pain experience, such as expectations, desire for pain relief, and anxiety. Twenty religious and twenty non-religious healthy volunteers were exposed to painful electrical stimulation during internal prayer to God, a secular contrast condition, and a pain-only control condition. Subjects rated expected pain intensity levels, desire for pain relief, and anxiety before each trial and pain intensity and pain unpleasantness immediately after on mechanical visual analogue scales. Autonomic and cardiovascular measures provided continuous non-invasive objective means for assessing the potential analgesic effects of prayer. Prayer reduced pain intensity by 34 % and pain unpleasantness by 38 % for religious participants, but not for non-religious participants. For religious participants, expectancy and desire predicted 56-64 % of the variance in pain intensity scores, but for non-religious participants, only expectancy was significantly predictive of pain intensity (65-73 %). Conversely, prayer-induced reduction in pain intensity and pain unpleasantness were not followed by autonomic and cardiovascular changes.

    Full Text Available Abstract Background Methotrexate (MTX uptake is mediated by the reduced folate carrier (RFC. Defective drug uptake in association with decreased RFC expression is a common mechanism of MTX resistance in many tumor types. Heavy promoter methylation was previously identified as a basis for the complete silencing of RFC in MDA-MB-231 breast cancer cells, its role and prevalence in RFC transcription regulation are, however, not widely studied. Methods In the current study, RFC promoter methylation was assessed using methylation specific PCR in a panel of malignant cell lines (n = 8, including MDA-MB-231, and M805, a MTX resistant cell line directly established from the specimen of a patient with malignant fibrohistocytoma, whom received multiple doses of MTX. A quantitative approach of real-time PCR for measuring the extent of RFC promoter methylation was developed, and was validated by direct bisulfite genomic sequencing. RFC mRNA levels were determined by quantitative real-time RT-PCR and were related to the extent of promoter methylation in these cell lines. Results A partial promoter methylation and RFC mRNA down-regulation were observed in M805. Using the quantitative approach, a reverse correlation (correlation coefficient = -0.59, p Conclusion This study further suggests that promoter methylation is a potential basis for MTX resistance. The quantitative correlation identified in this study implies that promoter methylation is possibly a mechanism involved in the fine regulation of RFC transcription.

    Full Text Available This article deals with an analysis of the world sugar market, and specifically focuses on the supply and demand of refined sugar and their main determinants. The article first identifies the main determinants of the world supply of and demand for sugar, and further, their effect on such variables is quantified. Further, the component correlations on the selected market are analyzed. This consists of the identification of the factors affecting the production of refined sugar, as one of the main elements of the supply of sugar, as well as an analysis of the world price of sugar, as one of the significant factors affecting the world sugar market. The said correlations are quantified with the utilization of regression analysis on the basis of time series of the individual variables within the years 1980–2010. On the basis of the conducted analysis, the main determinants of the sugar supply on the world market within the analyzed period, for which an effect has been established both from an economic viewpoint, as well as from a statistical viewpoint, can be considered to be sugar reserves, its price and the acreage of sugarcane. The main determinant of the demand for sugar is, according to the conducted analysis, the global GDP on a new value level, as well as converted to one inhabitant. Further, the analysis also established the effect of the price of sugar and its reserves on the world production of refined sugar, and, last but not least, also the long-term tendency in the development of the world price of sugar. The analysis has proven significant influence of refined sugar supply, reserves of refined sugar, its price and area of sugar cane on sugar supply. Then, the analysis detected GDP as the main determinant of the sugar demand and the long memory in sugar prices. Finally, the influence of delayed price, reserves and delayed reserves on production has been proven.

    Do BRCA1/2 mutation carriers have a compromised ovarian reserve compared to proven non-carriers, based on serum anti-Müllerian hormone (AMH) levels? BRCA1/2 mutation carriers do not show a lower serum AMH level in comparison to proven non-carriers, after adjustment for potential confounders. It has been suggested that the BRCA genes play a role in the process of ovarian reserve depletion, although previous studies have shown inconsistent results regarding the association between serum AMH levels and BRCA mutation status. Hence, it is yet unclear whether BRCA1/2 mutation carriers may indeed be at risk of a reduced reproductive lifespan. STUDY DESIGN, SIZE, DURATION: A multicenter, cross-sectional study was performed between January 2012 and February 2015 in 255 women. We needed to include 120 BRCA1/2 mutation carriers and 120 proven non-carriers to demonstrate a difference in AMH levels of 0.40 µg/l (SD ± 0.12 µg/l, two-sided alpha-error 0.05, power 80%). Healthy women aged 18-45 years who were referred to the Clinical Genetics Department and applied for predictive BRCA1/2 testing because of a familial BRCA1/2 mutation were asked to participate. A cross-sectional assessment was performed by measuring serum AMH levels and filling out a questionnaire. Multivariate linear regression analyses adjusted for age, current smoking and current hormonal contraceptive use were performed on log-transformed serum AMH levels. Out of 823 potentially eligible women, 421 (51.2%) were willing to participate, and of those, 166 (39%) did not meet our inclusion criteria. Two hundred and fifty-five women were available for analyses; 124 BRCA1/2 mutation carriers and 131 proven non-carriers. The median [range] AMH level in carriers was 1.90 µg/l [0.11-19.00] compared to 1.80 µg/l [0.11-10.00] in non-carriers (P = 0.34). Adjusted linear regression analysis revealed no reduction in AMH level in the carriers (relative change = 0.98 (95%CI, 0.77-1.22); P = 0.76). Participants

  15. Gestational or acute restraint in adulthood reduces levels of 5α-reduced testosterone metabolites in the hippocampus and produces behavioral inhibition of adult male rats

    Full Text Available Stressors, during early life or adulthood, can alter steroid-sensitive behaviors, such as exploration, anxiety, and/or cognitive processes. We investigated if exposure to acute stressors in adulthood may alter behavioral and neuroendocrine responses of male rats that were exposed to gestational stress or not. We hypothesized that rats exposed to gestational and acute stress may show behavioral inhibition, increased corticosterone, and altered androgen levels in the hippocampus. Subjects were adult, male offspring of rat dams that were restrained daily on gestational days 14-20, or did not experience this manipulation. Immediately before testing, rats were restraint-stressed for 20 minutes or not. During week 1, rats were tested in a battery of tasks, including the open field, elevated plus maze, social interaction, tailflick, pawlick, and defensive burying tasks. During week 2, rats were trained and tested 24 hours later in the inhibitory avoidance task. Plasma corticosterone and androgen levels, and hippocampal androgen levels, were measured in all subjects. Gestational and acute restraint stress increased plasma levels of corticosterone, and reduced levels of testosterone’s 5α-reduced metabolites, dihydrotestosterone and 3α-androstanediol, but not the aromatized metabolite, estradiol, in plasma or the hippocampus. Gestational and acute restraint stress reduced central entries made in the open field, and latencies to enter the shock-associated side of the inhibitory avoidance chamber during testing. Gestational stress reduced time spent interacting with a conspecific. These data suggest that gestational and acute restraint stress can have actions to produce behavioral inhibition coincident with increased corticosterone and decreased 5α-reduced androgens of adult male rats. Thus, gestational stress altered neural circuits involved in the neuroendocrine response to acute stress in early adulthood.

    Grape berry composition mainly consists of primary and secondary metabolites. Both are sensitive to environment and viticultural management. As a consequence, climate change can affect berry composition and modify wine quality and typicity. Leaf removal techniques can impact berry composition by modulating the source-to-sink balance and, in turn, may mitigate some undesired effects due to climate change. The present study investigated the balance between technological maturity parameters such as sugars and organic acids, and phenolic maturity parameters such as anthocyanins in response to source-sink modulation. Sugar, organic acid, and anthocyanin profiles were compared under two contrasting carbon supply levels in berries of cv. Cabernet Sauvignon and Sangiovese collected at 9 and 14 developmental stages respectively. In addition, whole-canopy net carbon exchange rate was monitored for Sangiovese vines and a mathematic model was used to calculate the balance between carbon fixation and berry sugar accumulation. Carbon limitation affected neither berry size nor the concentration of organic acids at harvest. However, it significantly reduced the accumulation of sugars and total anthocyanins in both cultivars. Most interestingly, carbon limitation decreased total anthocyanin concentration by 84.3% as compared to the non source-limited control, whereas it decreased sugar concentration only by 27.1%. This suggests that carbon limitation led to a strong imbalance between sugars and anthocyanins. Moreover, carbon limitation affected anthocyanin profiles in a cultivar dependent manner. Mathematical analysis of carbon-balance indicated that berries used a higher proportion of fixed carbon for sugar accumulation under carbon limitation (76.9%) than under carbon sufficiency (48%). Thus, under carbon limitation, the grape berry can manage the metabolic fate of carbon in such a way that sugar accumulation is maintained at the expense of secondary metabolites.

    Inverted liquid sugar is a mixture of sucrose, glucose and fructose, which shows its relevant characteristic on high sweetness power. Ionizing radiation has been applied to different kind of food and ingredients for different reasons, such as pathogens reduction, disinfestations, quarantine purposes, ripening delay among others. Radiation from an electron beam can be utilized as a technique to treat this ingredient because it can process a great volume of material per unit of time. The main goal of this paper was to verify the effect of radiation on the properties of inverted liquid sugar. This ingredient was irradiated in an electron accelerator (Radiation Dynamics) at a dose ranging from 5 to 50 kGy. Sucrose content measurements were reduced by 23% at 30 kGy when compared to control and the reduced sugar content increased around 11%. Density and moisture values were not affected by radiation. The total soluble solids (Brix degrees) rose in function of the absorbed dose. (authors)

    Increased consumption of sugar-sweetened beverages (SSBs) is a critical nutrition problem in the U.S. and has been identified as a key contributor to the current epidemic of obesity among adolescents. Up to date, little is known on how this high level of SSBs consumption can be reduced. Recently, environmental and policy interventions have been advocated as powerful strategies to address the epidemic. While there is a growing consensus that food environments and policies play important roles ...

    Excess consumption of added dietary sugars is related to multiple metabolic problems and adverse health conditions. Identifying the modifiable social cognitive and motivational constructs that predict sugar consumption is important to inform behavioral interventions aimed at reducing sugar intake. We tested the efficacy of an integrated dual-process, dual-phase model derived from multiple theories to predict sugar consumption. Using a prospective design, university students (N = 90) completed initial measures of the reflective (autonomous and controlled motivation, intentions, attitudes, subjective norm, perceived behavioral control), impulsive (implicit attitudes), volitional (action and coping planning), and behavioral (past sugar consumption) components of the proposed model. Self-reported sugar consumption was measured two weeks later. A structural equation model revealed that intentions, implicit attitudes, and, indirectly, autonomous motivation to reduce sugar consumption had small, significant effects on sugar consumption. Attitudes, subjective norm, and, indirectly, autonomous motivation to reduce sugar consumption predicted intentions. There were no effects of the planning constructs. Model effects were independent of the effects of past sugar consumption. The model identified the relative contribution of reflective and impulsive components in predicting sugar consumption. Given the prominent role of the impulsive component, interventions that assist individuals in managing cues-to-action and behavioral monitoring are likely to be effective in regulating sugar consumption.

    Magnesium has been reported to improve glucose utilization in diabetes mellitus. However, information on its effects on anemic and inflammatory markers in diabetes mellitus is limited. This study investigated the effect of oral magnesium (Mg) treatment on some markers of anemia and inflammation in 25 male Wistar rats. Rats (200 ± 15 g) were randomly divided into five groups (n = 5). Group 1 was control (received orally 0.2 mL distilled water daily), group 2 (Diabetic Untreated), group 3 (Diabetic Mg treated-100 mg/kg bw), group 4 (Diabetic Mg treated-250 mg/kg bw), group 5 (Diabetic Insulin treated-1 IU/kg bw). Diabetes was induced with a single dose of alloxan (100 mg/kg intraperitoneal (i.p.)). All treatments were done for 14 days. Anemic and inflammatory markers were investigated on blood samples obtained from each animal using standard laboratory methods. Significant increase (p DMg 100 (5.86 ± 0.74 × 10 9 /L) and DMg 250 (5.06 ± 0.78 × 10 9 /L). Hemoglobin concentration, packed cell volume (PCV) and red blood cell (RBC) count was decreased (p DMg 100, and DI rats. Erythrocyte sedimentation rate (ESR) was significantly increased (p DMg 100, DMg 250, and DI groups. Fibrinogen level was increased (p DMg 100 (0.30 ± 0.03 g/dL), DMg 250 (0.22 ± 0.04 g/dL), and DI (0.36 ± 0.02 g/dL) rats were comparable to control (0.26 ± 0.02 g/dL). Total protein, albumin, and globulin levels were decreased in DU rats compared to normal control, DMg 100, DMg 250, and DI rats. In conclusion, anemia and increased hematologic and metabolic inflammatory markers may be associated with untreated diabetes mellitus. Treatment of alloxan-induced diabetic rats with magnesium improved the anemic state and reduced hematologic and metabolic inflammatory markers.

    Hydroxychloroquine (HCQ) was suggested to play a role in lowering antiphospholipid antibody titers and preventing thrombotic recurrences in patients with systemic lupus erythematosus, but few data are available in patients with primary antiphospholipid syndrome (PAPS). In this retrospective, propensity score-matched cohort study, we evaluated the impact of HCQ on aPL titers and the incidence of thrombotic events in 57 exposed patients compared to 57 not exposed patients. These were matched for sex/type of disease onset/follow-up duration, age at the beginning of the follow-up ±10 years and initial date of the follow-up ±5 years. At baseline, no significant differences in demographical, clinical and serological features were observed between the two groups except for positive anti-extractable nuclear antigen antibodies (21 % in HCQ exposed vs 0 % in HCQ not exposed, P = 0.001). Both the levels of IgG anti-cardiolipin and IgG/IgM anti-β2-glycoprotein I (anti-β2GPI) were significantly reduced at end of follow-up compared to the baseline in HCQ-exposed patients, while there were no differences in the other group. Moreover, anti-β2GPI IgG titers were significantly decreased when the end of follow-up was compared between the two groups (P < 0.002). Among patients with a history of thrombosis, the annual incidence of recurrence was 1.16 % in HCQ exposed and 1.71 % in not exposed patients, with a significant reduction in the incidence of arterial events (0 vs 1.14 %). This study shows a strong reduction in aPL titers together with an apparent decrease in the incidence of arterial thrombosis recurrence in PAPS patients treated with HCQ.

  3. Ecological feedbacks can reduce population-level efficacy of wildlife fertility control

    2014-01-01

    1. Anthropogenic stress on natural systems, particularly the fragmentation of landscapes and the extirpation of predators from food webs, has intensified the need to regulate abundance of wildlife populations with management. Controlling population growth using fertility control has been considered for almost four decades, but nearly all research has focused on understanding effects of fertility control agents on individual animals. Questions about the efficacy of fertility control as a way to control populations remain largely unanswered. 2. Collateral consequences of contraception can produce unexpected changes in birth rates, survival, immigration and emigration that may reduce the effectiveness of regulating animal abundance. The magnitude and frequency of such effects vary with species-specific social and reproductive systems, as well as connectivity of populations. Developing models that incorporate static demographic parameters from populations not controlled by contraception may bias predictions of fertility control efficacy. 3. Many population-level studies demonstrate that changes in survival and immigration induced by fertility control can compensate for the reduction in births caused by contraception. The most successful cases of regulating populations using fertility control come from applications of contraceptives to small, closed populations of gregarious and easily accessed species. 4. Fertility control can result in artificial selection pressures on the population and may lead to long-term unintentional genetic consequences. The magnitude of such selection is dependent on individual heritability and behavioural traits, as well as environmental variation. 5. Synthesis and applications. Understanding species' life-history strategies, biology, behavioural ecology and ecological context is critical to developing realistic expectations of regulating populations using fertility control.

    Full Text Available The sugars fructose, glucose, maltose, and sucrose were quantified in seven tissues of Zamia muricata Willd. to determine their distribution throughout various organs of a model cycad species, and in lateral structural roots of 18 cycad species to determine the variation in sugar concentration and composition among species representing every cycad genus. Taproot and lateral structural roots contained more sugars than leaf, stem, female strobilus, or coralloid roots. For example, taproot sugar concentration was 6.4-fold greater than stem sugar concentration. The dominant root sugars were glucose and fructose, and the only detected stem sugar was sucrose. Sucrose also dominated the sugar profile for leaflet and coralloid root tissue, and fructose was the dominant sugar in female strobilus tissue. Maltose was a minor constituent of taproot, leaflet, and female strobilus tissue, but absent in other tissues. The concentration of total free sugars and each of the four sugars did not differ among genera or families. Stoichiometric relationships among the sugars, such as the quotient hexoses/disaccharides, differed among organs and families. Although anecdotal reports on cycad starch have been abundant due to its historical use as human food and the voluminous medical research invested into cycad neurotoxins, this is the first report on the sugar component of the non-structural carbohydrate profile of cycads. Fructose, glucose, and sucrose are abundant in cycad tissues, with their relative abundance highly contrasting among organs. Their importance as forms of carbon storage, messengers of information, or regulators of cycad metabolism have not been determined to date.

  6. Catalytic production of sugar alcohols (polyols) and their application

    Energy Technology Data Exchange (ETDEWEB)

    Albert, R; Straetz, A; Vollheim, G

    1980-07-01

    The article surveys the numerous applications of the principal sugar alcohols sorbitol and xylitol and their world production in 1978. Nowadays, the industrial production of sugar alcohols is almost exclusively by catalytic hydrogenation of the corresponding sugars; thus sorbitol is manufactured by hydrogenation of D-glucose, xylitol by hydrogenation of xylose, and mannitol by hydrogenation of invert sugar or fructose. Some 80% of the world production of sugar alcohols are manufactured in batch suspension processes using Raney nickel catalysts. Apart from the Atlas Powder continuous suspension process employing nickel-carrier catalysts, continuous processes have recently been developed which use Raney nickel and prove more economical owing to the lower catalyst costs. Trickling processes with fixed catalyst continue to play a minor role. Available production capacity based on batch suspension processes can be expanded by process optimization and new catalyst developments. A newly developed special Raney nickel catalyst reduces the specific catalyst consumption by about 50%.

    Improvement of the energy balance and efficiency for reduced input of cropping systems is one of the main goals for the cultivation of energy crops. In this field study, two sugar crops for bioethanol production were cultivated under different soil tillage management (conventional; no tillage) and mineral nitrogen application (0, 75, 150 kg N ha"−"1): sweet sorghum and sugar beet. The energy performance and efficiency along the bioethanol supply chain were analysed and compared. Both of these crops showed good growth adaptation to the different soil and nitrogen management, and thus the energy return, resource and energy efficiencies were significantly improved in the low-input system. Sweet sorghum provided better responses in terms of water and nitrogen use efficiency for biomass accumulation, as well as its energy yield and net gain, compared to sugar beet, whereas sugar beet showed higher energy efficiency than sorghum. According to these data, both of these crops can be cultivated in a Mediterranean environment with low energy input, which guarantees good crop and energy performances for biofuel strategy planning. - Highlights: • Two sugar crops for the bioethanol supply chain were evaluated. • Energy performances and efficiencies were assessed under different energy input. • Sugar yield resulted not compromised by the different crop management. • The energy gain was improved with low energy input at field level. • Sweet sorghum gave the highest energy yield, sugar beet the energy efficiency.

    Trauma patients are triaged by the severity of their injury or need for intervention while en route to the trauma center according to trauma activation protocols that are institution specific. Significant research has been aimed at improving these protocols in order to optimize patient outcomes while striving for efficiency in care. However, it is known that patients are often undertriaged or overtriaged because protocol adherence remains imperfect. The goal of this quality improvement (QI) project was to improve this adherence, and thereby reduce the triage error. It was conducted as part of the formal undergraduate medical education curriculum at this institution. A QI team was assembled and baseline data were collected, then 2 Plan-Do-Study-Act (PDSA) cycles were implemented sequentially. During the first cycle, a novel web tool was developed and implemented in order to automate the level assignment process (it takes EMS-provided data and automatically determines the level); the tool was based on the existing trauma activation protocol. The second PDSA cycle focused on improving triage accuracy in isolated, less than 10% total body surface area burns, which we identified to be a point of common error. Traumas were reviewed and tabulated at the end of each PDSA cycle, and triage accuracy was followed with a run chart. This study was performed at Vanderbilt University Medical Center and Medical School, which has a large level 1 trauma center covering over 75,000 square miles, and which sees urban, suburban, and rural trauma. The baseline assessment period and each PDSA cycle lasted 2 weeks. During this time, all activated, adult, direct traumas were reviewed. There were 180 patients during the baseline period, 189 after the first test of change, and 150 after the second test of change. All were included in analysis. Of 180 patients, 30 were inappropriately triaged during baseline analysis (3 undertriaged and 27 overtriaged) versus 16 of 189 (3 undertriaged and 13

    Since the invention of sugar, added sugars bring us enjoyment. As consumption continues to rise, especially the advent of sugary drinks makes it easier for people to consume added sugars, less sugars and reduced sugars have also become a of concern around the world. In recent years, in WHO and several countries, tax on sugary beverages has been designed to reduce the intake of sugar and prevent the economic costs of obesity and other diseases. This paper reviews the WHO's proposal on sugary drinks tax and the progress of sugary drinks tax in Hungary, Finland, France, Mexico, the United States, South Africa and other countries and regions. The effect of policy on sugary drinks tax was analyzed and considered. Suggestion and support for the progress of China's reduced sugars was provided in the last.

    The objective of this study was to evaluate differences in calories, nutrient content, overall healthfulness, and use of sweetener ingredients between products with and without sugar claims. Consumers assume products with sugar claims are healthier and lower in calories. It is therefore important claims be found on comparatively healthier items. This study is a cross-sectional analysis of the University of Toronto's 2013 Food Label Database. Subcategories where at least 5% of products (and n ≥ 5) carried a sugar claim were included (n = 3048). Differences in median calorie content, nutrient content, and overall healthfulness, using the Food Standards Australia/New Zealand Nutrient Profiling Scoring criterion, between products with and without sugar claims, were determined. Proportion of products with and without claims that had excess free sugar levels (≥10% of calories from free sugar) and that contained sweeteners was also determined. Almost half (48%) of products with sugar claims contained excess free sugar, and a greater proportion contained sweeteners than products without such claims (30% vs 5%, χ 2 = 338.6, p contents than products without claims. At the subcategory level, reductions in free sugar contents were not always met with similar reductions in calorie contents. This study highlights concerns with regards to the nutritional composition of products bearing sugar claims. Findings can support educational messaging to assist consumer interpretation of sugar claims and can inform changes in nutrition policies, for example, permitting sugar claims only on products with calorie reductions and without excess free sugar.

    A lower serum cholesterol level was recently shown to be one of the causes of stroke in an epidemiological study. Spontaneously hypertensive rats stroke-prone (SHRSP) have lower serum cholesterol levels than normotensive Wistar-Kyoto rats (WKY). To elucidate the mechanisms responsible for the lower serum cholesterol levels in SHRSP, we determined whether the amounts of cholesterol biosynthetic enzymes or the receptor and transporter involved in cholesterol uptake and efflux in the liver were altered in SHRSP. When the mRNA levels of seven cholesterol biosynthetic enzymes were measured using real-time polymerase chain reaction (PCR), farnesyl pyrophosphate synthase and squalene epoxidase (SQE) levels in the liver of SHRSP were significantly lower than those in WKY. SQE protein levels were significantly reduced in tissues other than the brain of SHRSP. No significant differences were observed in low-density lipoprotein (LDL) receptor (uptake of serum LDL-cholesterol) or ATP-binding cassette transporter A1 (efflux of cholesterol from the liver/formation of high-density lipoprotein (HDL)) protein levels in the liver and testis between SHRSP and WKY, whereas scavenger receptor class B type 1 (SRB1: uptake of serum HDL-cholesterol) protein levels were higher in the livers of SHRSP. These results indicated that the lower protein levels of SQE and higher protein levels of SRB1 in the liver were involved in the reduced serum cholesterol levels in SHRSP.

    Impaired glucose tolerance and diabetes mellitus have become major health issues even in non-industrialized countries. As access to clinical management is often poor, dietary interventions and alternative medicines are required. For bitter gourd, Momordica charantia L., antidiabetic properties have been claimed. The main objective of the intervention study was to assess antidiabetic effects of daily bitter gourd consumption of 2.5g powder over the course of eight weeks among prediabetic individuals. In a randomized placebo-controlled single blinded clinical trial, 52 individuals with prediabetes were studied after consuming a bitter gourd or a cucumber juice. For reducing the impact of between subject differences in the study population, a crossover design was chosen with eight weeks for each study period and four weeks washout in between. Fasting plasma glucose was chosen as the primary outcome variable. Comparing the different exposures, the CROS analysis (t=-2.23, p=0.031, r=0.326) revealed a significant difference in the change of FPG of 0.31mmol/L (5.6mg/dL) with a trend (R 2 =0,42387). The number of 44 finally complete data sets achieved a power of 0.82, with a medium-to-large effect size (Cohen's d 0.62). The effect was also proven by a general linear mixed model (estimate 0.31; SE: 0.12; p: 0.01; 95%CI: 0.08; 0.54). Not all participants responded, but the higher the initial blood glucose levels were, the more pronounced the effect was. No serious adverse effects were observed. Bitter gourd supplementation appeared to have benefits in lowering elevated fasting plasma glucose in prediabetes. The findings should be replicated in other intervention studies to further investigate glucose lowering effects and the opportunity to use bitter gourd for dietary self-management, especially in places where access to professional medical care is not easily assured.

    Wheat is increasingly used as a dual-purpose crop (for forage and grain production) worldwide. Plants encounter low temperatures in winter, which commonly results in sugar accumulation. High sugar levels might have a positive impact on forage digestibility, but may also lead to an increased risk of bloat. We hypothesized that cultivars with a lower capacity to accumulate sugars when grown under cold conditions may have a lower bloat risk than higher sugar-accumulating genotypes, without showi...

  18. European Sugar Market – Impact of Quota System

    2015-01-01

    Full Text Available The European agricultural market has been criticized for its heavy regulations and subsidization. The sugar market is one of the most regulated ones; however, this will change radically in 2017 when the current system of production quotas will end. The aim of this paper is to present the basic characteristics of the EU quota sugar market. The analysis identifies the main drivers of EU sugar market and their position within the EU sugar market. The paper identifies especially those drivers/companies/alliances which take control over the EU sugar production realized under the quota production system. The paper also highlights the level of EU sugar market concentration and also identifies those countries and companies which are the main leaders in the sugar production area realized under the quota system. Based on the results deriving from the paper, it is possible to characterize the EU sugar market as a heavily concentrated one – nearly 75% (10 mil. tonnes of the quota is controlled by five multinational companies only; these companies are operating more than 50% of all the available sugar plants located in the EU. These multinational alliances are also in control of the production capacities of their subsidiaries. In most countries, this causes serious problems as the given quota is controlled by one or two producers only. The EU sugar market is extremely concentrated especially if we take into consideration the location of each alliance’s headquarters. The majority of production capacities are under (the control of especially German and French companies. These two countries are also the main beneficiaries in relation to the EU sugar production quota system.

    Sugar-sweetened beverages and added sugars (monosaccharides and disaccharides) in the diet are associated with obesity, diabetes, and cardiovascular disease, which are all risk factors for decline in physical function among older adults. The aim of this study was to examine the association between added sugars in the diet and incidence of frailty in older people. Data were taken from 1973 Spanish adults ≥60 y old from the Seniors-ENRICA cohort. In 2008-2010 (baseline), consumption of added sugars (including those in fruit juices) was obtained using a validated diet history. Study participants were followed up until 2012-2013 to assess frailty based on Fried's criteria. Statistical analyses were performed with logistic regression adjusted for age, sex, education, smoking status, body mass index, energy intake, self-reported comorbidities, Mediterranean Diet Adherence Score (excluding sweetened drinks and pastries), TV watching time, and leisure-time physical activity. Compared with participants consuming added sugars (lowest tertile), those consuming ≥36 g/d (highest tertile) were more likely to develop frailty (OR: 2.27; 95% CI: 1.34, 3.90; P-trend = 0.003). The frailty components "low physical activity" and "unintentional weight loss" increased dose dependently with added sugars. Association with frailty was strongest for sugars added during food production. Intake of sugars naturally appearing in foods was not associated with frailty. The consumption of added sugars in the diet of older people was associated with frailty, mainly when present in processed foods. The frailty components that were most closely associated with added sugars were low level of physical activity and unintentional weight loss. Future research should determine whether there is a causal relation between added sugars and frailty.

  20. INVESTIGATION OF BACTERIOSTATIC PROPERTIES OF CHLORINATED COMPOUNDS FOR BEET-SUGAR INDUSTRY

    2014-01-01

    Full Text Available Summary. One of the major causes of decline in the quality of granulated sugar is bacterial contamination of sugar beet. This is due to the fact that the beet-sugar industry is a good object for the development of different groups of microorganisms. The main sources of infection of products of sugar manufacture can be soil, water, air, packaging, packaging materials, vehicles, clothing, equipment. The higher the beet contamination with the microorganisms, the more they decompose sucrose and secrete metabolic byproducts. In this regard, there is a need to reduce the negative impact of various groups of microorganisms and to minimize the loss of sucrose from decomposition. In accordance with the problem given the studies to determine the bacteriostatic properties of chlorinated compounds for sugar production were carried out. We used the cultivated fluid colonized with a pure culture of Leuconostoc mesenteroides and reagent treated as an object of study. In the experiments, we determined the accumulation of biomass of L. mesenteroides with nephelometric method by measuring the optical density of bacterial suspension. It was found out that after 24 hours of bacterial culturing the level of optical density in the control and active acidity were considerably higher compared with the sample treated with germicide. The number of microorganisms in the nutrient medium was determined by Vinogradsky-Shulgina-Brid’s. According to the study in the control is 1,7*10^16, in experiment with the introduction of the chlorinated compound it is 5,8*10^14. The experimental results show that the investigated chlorinated compound has bacteriostatic action against grampositive cocci saprophytic of L. mesenteroides and can be recommended for use in a sugar beet production.

    Caries increment is affected by sugar-sweetened beverage (SSB) consumption. Taxing SSBs could reduce sugar consumption and caries increment. The authors aimed to estimate the impact of a 20% SSB sales tax on caries increment and associated treatment costs (as well as the resulting tax revenue) in the context of Germany. A model-based approach was taken, estimating the effects for the German population aged 14 to 79 y over a 10-y period. Taxation was assumed to affect beverage-associated sugar consumption via empirical demand elasticities. Altered consumption affected caries increments and treatment costs, with cost estimates being calculated under the perspective of the statutory health insurance. National representative consumption and price data were used to estimate tax revenue. Microsimulations were performed to estimate health outcomes, costs, and revenue impact in different age, sex, and income groups. Implementing a 20% SSB sales tax reduced sugar consumption in nearly all male groups but in fewer female groups. The reduction was larger among younger than older individuals and among those with low income. Taxation reduced caries increment and treatment costs especially in younger (rather than older) individuals and those with low income. Over 10 y, mean (SD) net caries increments at the population level were 82.27 (1.15) million and 83.02 (1.08) million teeth at 20% and 0% SSB tax, respectively. These generated treatment costs of 2.64 (0.39) billion and 2.72 (0.35) billion euro, respectively. Additional tax revenue was 37.99 (3.41) billion euro over the 10 y. In conclusion and within the limitations of this study's perspective, database, and underlying assumptions, implementing a 20% sales tax on SSBs is likely to reduce caries increment, especially in young low-income males, thereby also reducing inequalities in the distribution of caries experience. Taxation would also reduce treatment costs. However, these reductions might be limited in the total

    The purpose of the present study was to assess the dietary fat intake, glucose, insulin, Homeostasis model assessment for insulin resistance HOMA-IR, and endotoxin levels and correlate them with adipokine serum concentrations in obese adolescents who had been admitted to long-term interdisciplinary weight-loss therapy. The present study was a longitudinal clinical intervention of interdisciplinary therapy. Adolescents (n = 18, aged 15-19 y) with a body mass index > 95th percentile were admitted and evaluated at baseline and again after 1 year of interdisciplinary therapy. We collected blood samples, and IL-6, adiponectin, and endotoxin concentrations were measured by ELISA. Food intake was measured using 3-day diet records. In addition, we assessed glucose and insulin levels as well as the homeostasis model assessment for insulin resistance (HOMA-IR). The most important finding from the present investigation was that the long-term interdisciplinary lifestyle therapy decreased dietary fat intake and endotoxin levels and improved HOMA-IR. We observed positive correlations between dietary fat intake and endotoxin levels, insulin levels, and the HOMA-IR. In addition, endotoxin levels showed positive correlations with IL-6 levels, insulin levels and the HOMA-IR. Interestingly, we observed a negative correlation between serum adiponectin and both dietary fat intake and endotoxin levels. The present results indicate an association between dietary fat intake and endotoxin level, which was highly correlated with a decreased pro-inflammatory state and an improvement in HOMA-IR. In addition, this benefits effect may be associated with an increased adiponectin level, which suggests that the interdisciplinary therapy was effective in improving inflammatory pathways.

    The incorporation and distribution of 14 C in leaf free sugars and amino acids of maize plants under magnesium deficiency and following their recovery was studied by the aid of Mg applied singly or in combination with the trace elements Co, Cr, and B. It was established that stress resulting from magnesium deficit causes considerable changes in free sugar and amino acid metabolism. Magnesium deficiency reduces the relative share of sugars and raises the share of amino acids. It leads to great changes also in the ratio of the individual substances - reduces succrose, glutamic acid, and -amino butyric acid, increases fructose, rafinose, glucose, alanine, aspartic acid and valine. During a 10-day period of plant recovery the metabolic changes of free sugars and amino acids occurring as a result of magnesium deficit are restored to normal condition. Under the conditions existing in this experiment Mg was capable to restore alone disturbances in free sugar and amino acid metabolism to the level observed in the control plants. The trace elements Co, Cr and B, used in combination with Mg, had no marked additive effect on the recovery process of free sugar and amino acid metabolic disturbances caused by Mg deficiency.

    Although nonhuman animal models have strongly suggested that vitamin D suppresses the renin-angiotensin system (RAS) and albuminuria, human data are largely lacking. The aim of this study was to examine the relationship between 25-hydroxyvitamin D [25-(OH)D] level and albuminuria and urinary angiotensinogen (UAGT) level in renal transplant recipients (RTRs). We also planned to investigate the effect of calcitriol treatment on albuminuria and UAGT level in these patients. A total of 124 nondiabetic RTRs participated in this study. UAGT level was positively correlated with the urinary albumin-creatinine ratio (UACR) in all patients (r = 0.855; P level (P = .02) were significantly higher in RTRs with low 25-(OH)D than in RTRs with normal 25-(OH)D level. RTRs with low 25-(OH)D level were randomized to receive either 0.25 μg/d calcitriol (n = 40) or placebo (n = 40). All of the parameters were assessed again 12 months later in both groups. The mean UACR (P = .014) and UAGT/UCr level (P = .012) were significantly lower in the calcitriol group than in the placebo group at the end of the study. Low 25-(OH)D status may be related to the elevation in albuminuria and UAGT, and calcitriol may have a beneficial effect on albuminuria through the inhibition of intrarenal RAS in RTRs.

    BACKGROUND Poor lifestyle behaviors are leading causes of preventable diseases globally. Added sugars contribute to a diet that is energy dense but nutrient poor and increase risk of developing obesity, cardiovascular disease, hypertension, obesity-related cancers, and dental caries. METHODS AND RESULTS For this American Heart Association scientific statement, the writing group reviewed and graded the current scientific evidence for studies examining the cardiovascular health effects of added sugars on children. The available literature was subdivided into 5 broad subareas: effects on blood pressure, lipids, insulin resistance and diabetes mellitus, nonalcoholic fatty liver disease, and obesity. CONCLUSIONS Associations between added sugars and increased cardiovascular disease risk factors among US children are present at levels far below current consumption levels. Strong evidence supports the association of added sugars with increased cardiovascular disease risk in children through increased energy intake, increased adiposity, and dyslipidemia. The committee found that it is reasonable to recommend that children consume ≤25 g (100 cal or ≈6 teaspoons) of added sugars per day and to avoid added sugars for children added sugars most likely can be safely consumed in low amounts as part of a healthy diet, few children achieve such levels, making this an important public health target.

    Understanding how cells make decisions, and why they make the decisions they make, is of fundamental interest in systems biology. To address this, we study the decisions made by E. coli on which genes to express when presented with two different sugars. It is well-known that glucose, E. coli's preferred carbon source, represses the uptake of other sugars by means of global and gene-specific mechanisms. However, less is known about the utilization of glucose-free sugar mixtures which are found in the natural environment of E. coli and in biotechnology. Here, we combine experiment and theory to map the choices of E. coli among 6 different non-glucose carbon sources. We used robotic assays and fluorescence reporter strains to make precise measurements of promoter activity and growth rate in all pairs of these sugars. We find that the sugars can be ranked in a hierarchy: in a mixture of a higher and a lower sugar, the lower sugar system shows reduced promoter activity. The hierarchy corresponds to the growth rate supported by each sugar- the faster the growth rate, the higher the sugar on the hierarchy. The hierarchy is 'soft' in the sense that the lower sugar promoters are not completely repressed. Measurement of the activity of the master regulator CRP-cAMP shows that the hierarchy can be quantitatively explained based on differential activation of the promoters by CRP-cAMP. Comparing sugar system activation as a function of time in sugar pair mixtures at sub-saturating concentrations, we find cases of sequential activation, and also cases of simultaneous expression of both systems. Such simultaneous expression is not predicted by simple models of growth rate optimization, which predict only sequential activation. We extend these models by suggesting multi-objective optimization for both growing rapidly now and preparing the cell for future growth on the poorer sugar. We find a defined hierarchy of sugar utilization, which can be quantitatively explained by

    To assess the influence of preexisting disabilities, age, and stroke service level on standardized IV thrombolysis (IVT) rates in acute ischemic stroke (AIS). We investigated standardized IVT rates in a retrospective registry-based study in 36,901 patients with AIS from the federal German state Baden-Wuerttemberg over a 5-year period. Patients admitted within 4.5 hours after stroke onset were selected. Factors associated with IVT rates (patient-level factors and stroke service level) were assessed using robust Poisson regression modeling. Interactions between factors were considered to estimate risk-adjusted mortality rates and potential IVT rates by service level (with stroke centers as benchmark). Overall, 10,499 patients (28.5%) received IVT. The IVT rate declined with service level from 44.0% (stroke center) to 13.1% (hospitals without stroke unit [SU]). Especially patients >80 years of age and with preexisting disabilities had a lower chance of being treated with IVT at lower stroke service levels. Interactions between stroke service level and age group, preexisting disabilities, and stroke severity (all p < 0.0001) were observed. High IVT rates seemed not to increase mortality. Estimated potential IVT rates ranged between 41.9% and 44.6% depending on stroke service level. Differences in IVT rates among stroke service levels were mainly explained by differences administering IVT to older patients and patients with preexisting disabilities. This indicates considerable further potential to increase IVT rates. Our findings support guideline recommendations to admit acute stroke patients to SUs. © 2016 American Academy of Neurology.

  16. Fatty acid synthase cooperates with glyoxalase 1 to protect against sugar toxicity.

    Full Text Available Fatty acid (FA metabolism is deregulated in several human diseases including metabolic syndrome, type 2 diabetes and cancers. Therefore, FA-metabolic enzymes are potential targets for drug therapy, although the consequence of these treatments must be precisely evaluated at the organismal and cellular levels. In healthy organism, synthesis of triacylglycerols (TAGs-composed of three FA units esterified to a glycerol backbone-is increased in response to dietary sugar. Saturation in the storage and synthesis capacity of TAGs is associated with type 2 diabetes progression. Sugar toxicity likely depends on advanced-glycation-end-products (AGEs that form through covalent bounding between amine groups and carbonyl groups of sugar or their derivatives α-oxoaldehydes. Methylglyoxal (MG is a highly reactive α-oxoaldehyde that is derived from glycolysis through a non-enzymatic reaction. Glyoxalase 1 (Glo1 works to neutralize MG, reducing its deleterious effects. Here, we have used the power of Drosophila genetics to generate Fatty acid synthase (FASN mutants, allowing us to investigate the consequence of this deficiency upon sugar-supplemented diets. We found that FASN mutants are lethal but can be rescued by an appropriate lipid diet. Rescued animals do not exhibit insulin resistance, are dramatically sensitive to dietary sugar and accumulate AGEs. We show that FASN and Glo1 cooperate at systemic and cell-autonomous levels to protect against sugar toxicity. We observed that the size of FASN mutant cells decreases as dietary sucrose increases. Genetic interactions at the cell-autonomous level, where glycolytic enzymes or Glo1 were manipulated in FASN mutant cells, revealed that this sugar-dependent size reduction is a direct consequence of MG-derived-AGE accumulation. In summary, our findings indicate that FASN is dispensable for cell growth if extracellular lipids are available. In contrast, FA-synthesis appears to be required to limit a cell

    2013-09-01

    Full Text Available Introduction: Optimal solutions for reducing diversion without worsening emergency department (ED crowding are unclear. We performed a systematic review of published simulation studies to identify: 1 the tradeoff between ambulance diversion and ED wait times; 2 the predicted impact of patient flow interventions on reducing diversion; and 3 the optimal regional strategy for reducing diversion.Methods: Data Sources: Systematic review of articles using MEDLINE, Inspec, Scopus. Additional studies identified through bibliography review, Google Scholar, and scientific conference proceedings. Study Selection: Only simulations modeling ambulance diversion as a result of ED crowding or inpatient capacity problems were included. Data extraction: Independent extraction by two authors using predefined data fields.Results: We identified 5,116 potentially relevant records; 10 studies met inclusion criteria. In models that quantified the relationship between ED throughput times and diversion, diversion was found to only minimally improve ED waiting room times. Adding holding units for inpatient boarders and ED-based fast tracks, improving lab turnaround times, and smoothing elective surgery caseloads were found to reduce diversion considerably. While two models found a cooperative agreement between hospitals is necessary to prevent defensive diversion behavior by a hospital when a nearby hospital goes on diversion, one model found there may be more optimal solutions for reducing region wide wait times than a regional ban on diversion.Conclusion: Smoothing elective surgery caseloads, adding ED fast tracks as well as holding units for inpatient boarders, improving ED lab turnaround times, and implementing regional cooperative agreements among hospitals.

    Background Correlating symptoms and physical examination findings with surgical levels based on common imaging results is not reliable. In patients who have no concordance between radiological and clinical symptoms, the surgical levels determined by conventional magnetic resonance imaging (MRI) and neurogenic examination (NE) may lead to a more extensive surgery and significant complications. We aimed to confirm that whether the use of diffusion tensor imaging (DTI) and paraspinal mapping (PM...

    As the scaling down of design rule for high-density memory device, the small depth of focus (DoF) budget may be deteriorated by focus leveling errors, which arises in unpredicted reflectivity from multilayer structures on the topographic wafer. The leveling sensors of ASML scanner use near infrared (NIR) range wavelength which can penetrate through most of films using in semiconductor fabrication such as photo-resist, bottom anti reflective coating (BARC) and dielectric materials. Consequently, the reflected light from underlying substructures would disturb leveling sensors from accurate leveling. The different pattern densities and layout characteristics between array and periphery of a memory chip are expected to result in different leveling signals. Furthermore, the process dependent variations between wafer central and edge areas are also considered to yield different leveling performances during wafer exposure. In this study, lower blind contact immunity was observed for peripheral contacts comparing to the array contacts especially around wafer edge region. In order to overcome this problem, a series of investigations have been carried out. The wafer edge leveling optimization through circuit dependent focus edge clearance (CDFEC) option doesn't get improvement. Air gauge improved process leveling (AGILE) function of ASML immersion scanner doesn't show improved result either. The ILD uniformity improvement and step height treatments around wafer edge such as edge exclusion of film deposition and bevel etching are also ineffective to mitigate the blind contact problem of peripheral patterns. Altering the etch hard-mask stack is finally found to be an effective approach to alleviate the issue. For instance, through either containing high temperature deposition advanced patterning film (APF) in the hard-mask or inserting higher opaque film such as amorphous Si in between the hard-mask stack.

    Negative moods have been associated with a tendency to prioritise local details in visual processing. The current study investigated the relation between depression and visual processing using the Navon task, a standard task of local and global processing. In the Navon task, global stimuli are presented that are made up of many local parts, and the participants are instructed to report the identity of either a global or a local target shape. Participants with a low self-reported level of depression showed evidence of the expected global processing bias, and were significantly faster at responding to the global, compared with the local level. By contrast, no such difference was observed in participants with high levels of depression. The reduction of the global bias associated with high levels of depression was only observed in the overall speed of responses to global (versus local) targets, and not in the level of interference produced by the global (versus local) distractors. These results are in line with recent findings of a dissociation between local/global processing bias and interference from local/global distractors, and support the claim that depression is associated with a reduction in the tendency to prioritise global-level processing.

  2. Experimental increase in baseline corticosterone level reduces oxidative damage and enhances innate immune response.

    Directory of Open Access Journals (Sweden)

    Csongor I Vágási

    Full Text Available Glucocorticoid (GC hormones are significant regulators of homeostasis. The physiological effects of GCs critically depend on the time of exposure (short vs. long as well as on their circulating levels (baseline vs. stress-induced. Previous experiments, in which chronic and high elevation of GC levels was induced, indicate that GCs impair both the activity of the immune system and the oxidative balance. Nonetheless, our knowledge on how mildly elevated GC levels, a situation much more common in nature, might influence homeostasis is limited. Therefore, we studied whether an increase in GC level within the baseline range suppresses or enhances condition (body mass, hematocrit and coccidian infestation and physiological state (humoral innate immune system activity and oxidative balance. We implanted captive house sparrows Passer domesticus with either 60 days release corticosterone (CORT or control pellets. CORT-treated birds had elevated baseline CORT levels one week after the implantation, but following this CORT returned to its pre-treatment level and the experimental groups had similar CORT levels one and two months following the implantation. The mass of tail feathers grown during the initial phase of treatment was smaller in treated than in control birds. CORT implantation had a transient negative effect on body mass and hematocrit, but both of these traits resumed the pre-treatment values by one month post-treatment. CORT treatment lowered oxidative damage to lipids (malondialdehyde and enhanced constitutive innate immunity at one week and one month post-implantation. Our findings suggest that a relatively short-term (i.e. few days elevation of baseline CORT might have a positive and stimulatory effect on animal physiology.

    Full Text Available To investigate the effect of water stress and rewatering on sugar beet yield and its corresponding photosynthetic parameters, and to provide the basis of water management for the sugar beet fields, pool experiments in an artificial proof canopy were set up to observe changes of beet net photosynthetic rate(Pn, transpiration rate(Tr, water use efficiency(WUE and stomatal limitation (Ls, intercellular CO2 oncentration(Ci, and PSⅡ maximum quantum yield(Fv/Fm. The results indicated that the diurnal variation of Tr and Pn in CK treatment (whole growth period replenishment at different times near "unimodal" type; and water shortage treatments presented "twin peaks" change. Diurnal transpiration capacity(DTC under water stress at sugar accumulation stage reduced by 70.16%~74.81% and diurnal photosynthetic capacity(DPC was 63.48%~69.96% lower than that of CK, while diurnal water use efficiency(WUEd increased by 19.28%~22.39%. Rehydration helped Tr and Pn recovery, but did not reach unstressed levels. Ls changes under extremely dry environment had a midday trough "twin peaks" feature, and Ci was at "double-dip" in consistent with the timing of Ls; Water stress inhibited and inactivated photochemical reaction center of midday PSⅡ. Water stress led to irreversible decrease in the Pn and Tr, and prolonged the Pn inefficient period, which become the important factor of influencing the sugar beet yield.

    Analysis of Defense Waste Processing Facility (DWPF) samples as slurries rather than as dried or vitrified samples is an effective way to reduce sample turnaround times. Slurries can be dissolved with a mixture of concentrated acids to yield solutions for elemental analysis by inductively coupled plasma-atomic emission spectroscopy (ICP-AES). Slurry analyses can be performed in eight hours, whereas analyses of vitrified samples require up to 40 hours to complete. Analyses of melter feed samples consisting of the DWPF borosilicate frit and either simulated or actual DWPF radioactive sludge were typically within a range of 3--5% of the predicted value based on the relative amounts of sludge and frit added to the slurry. The results indicate that the slurry analysis approach yields analytical accuracy and precision competitive with those obtained from analyses of vitrified samples. Slurry analyses offer a viable alternative to analyses of solid samples as a simple way to reduce analytical turnaround times

    Different levels of dried Jerusalem artichoke were fed to entire male pigs 1 week before slaughter. The objective was to investigate the effect on skatole level in the hindgut and in adipose tissue, as well as the effect on microflora and short-chain fatty acids (SCFA) in the hindgut. Five experimental groups (n = 11) were given different dietary treatments 7 days before slaughtering: negative control (basal diet), positive control (basal diet + 9% chicory-inulin), basal diet + 4.1% Jerusalem artichoke, basal diet + 8.1% Jerusalem artichoke and basal diet + 12.2% Jerusalem artichoke. Samples from colon, rectum, faeces and adipose tissue were collected. Effect of dietary treatment on skatole, indole and androstenone levels in adipose tissue and on skatole, indole, pH, dry matter (DM), microbiota and SCFA in the hindgut was evaluated. Feeding increasing levels of Jerusalem artichoke to entire male pigs reduced skatole in digesta from colon and in faeces (linear, P Jerusalem artichoke decreased DM content in colon and faeces and pH in colon (linear, P Jerusalem artichoke resulted in a reduced level of Clostridium perfringens in both colon and rectum (linear, P Jerusalem artichoke to diets for entire male pigs 1 week before slaughter resulted in a dose-dependent decrease in skatole levels in the hindgut and adipose tissue. The reduced skatole levels might be related to the decrease in C. perfringens and the increase in SCFA with subsequent reduction in pH.

    The structural simplicity of the bryophytes exposed them easily to water stress, forcing them to have physiological and biochemical mechanisms that enable them to survive. This study evaluated the variation of total soluble sugars and reducing sugars in relation to relative water content, in Pleurozium schreberi when faced with low water content in the Paramo de Chingaza (Colombia) and under simulated conditions of water deficit in the laboratory. we found that total sugars increase when the plant is dehydrated and returned to their normal content when re-hydrated moss, this could be interpreted as a possible mechanism of osmotic adjustment and osmoprotection of the cell content and cellular structure. Reducing sugars showed no significant variation, showing that monosaccharides do not have a protective role during dehydration.

    Type 2 diabetes (T2D) is a high risk factor for Alzheimer's disease (AD). Our previous study identified that hyperphosphorylation of tau protein, which is one of the pathophysiologic hallmarks of AD, also occurred in T2D rats' brain; while glucagon-like peptide-1 (GLP-1) mimetics, a type of drug used in T2D, could decrease the phosphorylation of tau, probably via augmenting insulin signaling pathway. The purpose of this study was to further explore the mechanisms that underlie the effect of exendin-4 (ex-4, a GLP-1 receptor agonist) in reducing tau phosphorylation. We found that peripheral ex-4 injection in T2D rats reduced hyperphosphorylation of tau protein in rat hippocampus, probably via increasing hippocampal insulin which activated insulin signaling. Furthermore, we found that ex-4 could neither activate insulin signaling, nor reduce tau phosphorylation in HT22 neuronal cells in the absence of insulin. These results suggested that insulin is required in reduction of tau hyperphosphorylation by ex-4 in brain rats with T2D. Copyright © 2015 Elsevier Inc. All rights reserved.

    For this cross-sectional study, we aimed to elucidate whether higher glycosylated hemoglobin (HbA1c) and glucose levels exert a negative impact on memory performance and hippocampal volume and microstructure in a cohort of healthy, older, nondiabetic individuals without dementia. In 141 individuals (72 women, mean age 63.1 years ± 6.9 SD), memory was tested using the Rey Auditory Verbal Learning Test. Peripheral levels of fasting HbA1c, glucose, and insulin and 3-tesla MRI scans were acquired to assess hippocampal volume and microstructure, as indicated by gray matter barrier density. Linear regression and simple mediation models were calculated to examine associations among memory, glucose metabolism, and hippocampal parameters. Lower HbA1c and glucose levels were significantly associated with better scores in delayed recall, learning ability, and memory consolidation. In multiple regression models, HbA1c remained strongly associated with memory performance. Moreover, mediation analyses indicated that beneficial effects of lower HbA1c on memory are in part mediated by hippocampal volume and microstructure. Our results indicate that even in the absence of manifest type 2 diabetes mellitus or impaired glucose tolerance, chronically higher blood glucose levels exert a negative influence on cognition, possibly mediated by structural changes in learning-relevant brain areas. Therefore, strategies aimed at lowering glucose levels even in the normal range may beneficially influence cognition in the older population, a hypothesis to be examined in future interventional trials.

    Adipokines enhance the synthesis of proinflammatory cytokines and matrix metalloproteinases (MMPs), which play a role in extracellular matrix degeneration. The aim of this study is to determine the levels of some adipokines, proinflammatory cytokines, and MMPs in the saliva of patients with periodontitis and healthy individuals and to evaluate the changes after non-surgical periodontal therapy (NSPT). Of 32 individuals included in the study, 17 had periodontitis and 15 had healthy gingiva. Saliva samples were obtained from all individuals. In patients with periodontitis, samples were recollected 3 and 6 months after NSPT. Visfatin, chemerin, progranulin, interleukin (IL)-1β, IL-8, MMP-8, and MMP-13 levels were measured using enzyme-linked immunosorbent assay. In patients with periodontitis, all of the parameters measured in the saliva were higher than those of healthy individuals. At 3 months, visfatin, progranulin, IL-8, and MMP-8 levels were significantly decreased compared with baseline values. The levels of other biochemical parameters, chemerin and IL-1β, were significantly decreased compared with baseline values at 6 months, and the levels became similar to those in healthy individuals. In the periodontitis group, positive correlations were found among visfatin and IL-8 (r = 0.909, P periodontal tissue in periodontitis by stimulating the expression of proinflammatory cytokines and MMPs.

    This study aimed to evaluate the level of taurine in plasma, and its association with the severity of motor and non-motor symptoms (NMS) and chronic levodopa treatment in Parkinson's disease (PD). Plasma taurine level was measured in treated PD (tPD), untreated PD (ntPD) and control groups. Motor symptoms and NMS were assessed using the Unified Parkinson's Disease Rating Scale, the short form of the McGill Pain Questionnaire, the Hamilton Depression Scale, the Scale for Outcomes in Parkinson's disease for Autonomic Symptoms and the Pittsburgh Sleep Quality Index. Longtime exposure to levodopa was indicated by its approximate cumulative dosage. The plasma taurine levels of PD patients were decreased when compared with controls and negatively associated with motor severity but not NMS. Moreover, tPD patients exhibited lower levels of plasma taurine than ntPD patients. Interestingly, plasma taurine levels negatively correlated with cumulative levodopa dosage in tPD. After controlling for potential confounders, the association between taurine and levodopa remained significant. Our study supports that taurine may play important roles in the pathophysiology of PD and the disturbances caused by chronic levodopa administration.

    To test (1) whether children will consume low-sugar ready-to-eat (RTE) cereals and (2) the effects of serving high- versus low-sugar cereals on the consumption of cereal, refined sugar, fresh fruit, and milk. Using an experimental design, we randomly assigned children (n = 91) who were attending summer day camp to receive a breakfast that included either the choice of 1 of 3 high-sugar cereals (high-sugar condition) or low-sugar cereals (low-sugar condition), as well as low-fat milk, orange juice, bananas, strawberries, and sugar packets. Participants served themselves and completed a background questionnaire after eating. Researchers measured the amount and calories consumed of each food. In both conditions, children reported "liking" or "loving" the cereal they chose. Children in the low-sugar cereal condition consumed, on average, slightly more than 1 serving of cereal (35 g), whereas children in the high-sugar condition consumed significantly more (61 g) and almost twice the amount of refined sugar in total (24.4 vs 12.5 g). Milk and total calories consumed did not differ significantly between conditions, but children in the low-sugar condition were more likely to put fruit on their cereal (54% vs 8%) and consumed a greater portion of total calories from fresh fruit (20% vs 13%). Compared with serving low-sugar cereals, high-sugar cereals increase children's total sugar consumption and reduce the overall nutritional quality of their breakfast. Children will consume low-sugar cereals when offered, and they provide a superior breakfast option.

    To validate known risk factors and identify a threshold level for serum insulin-like growth factor 1 (IGF-1) in the development of severe retinopathy of prematurity (ROP) in an ethnically diverse population at a tertiary neonatal unit, 2011-2013. A prospective cohort masked study was conducted. Serum IGF-1 levels at 31, 32 and 33 weeks were measured and risk factor data collected including gestational age (GA), birth weight (BW), absolute weight gain (AWG) and maternal ethnicity. The eventual ROP outcome was divided into two groups: minimal ROP (Stages 0 and 1) and severe ROP (Stage 2 or worse including Type 1 ROP). 36 patients were recruited: 14 had minimal ROP and 22 severe ROP. Significant differences between the groups were found in GA, BW, AWG and IGF-1 at 32 and 33 weeks. There was minimal rise in IGF-1 in Stage 2 patients and/or black patients (p=0.0013) between 32 and 33 weeks but no pragmatic threshold level of IGF-1 that could distinguish between minimal or severe ROP. There were significant differences in GA, BW, AWG and IGF-1 at 32 and 33 weeks between those babies with severe ROP and those with minimal ROP. However, there was no threshold level of IGF-1 at a time point between 31 and 33 weeks that can be used to exclude a large proportion of babies from screening. We also found ethnic differences in IGF-1 levels with infants born to black mothers having significantly lower IGF-1 levels at 32 and 33 weeks gestation. The determination of ROP risk using IGF-1 is a race-specific phenomenon. Published by the BMJ Publishing Group Limited.

    The environmental organisation NOAH has proposed carrying out an environmental assessment of two different sugar productions (using sugar beet or sugar cane) in order to illustrate which of the systems has a higher environmental impact for sugar consumption in Denmark. Therefore a comparison...... will be made between sugar from sugar beet produced in Denmark versus sugar produces from sugar cane in a tropical country, Brazil, and transported afterwards to Denmark. To evaluate the environmental aspects of these two product systems a Life Cycle Assessement (LCA) will be carried out.From the results...... obtained in the present LCA of sugar produces from sugar canes or sugar beet it is difficult to make an immediate choice between the two possibilities. Indeed, Quantitative results from the EDIP (Environmental Design of Industrial Products) software are globally similar for both ways of producing sugar...

  16. Rare sugars, d-allulose, d-tagatose and d-sorbose, differently modulate lipid metabolism in rats.

    Rare sugars including d-allulose, d-tagatose, and d-sorbose are present in limited quantities in nature; some of these rare sugars are now commercially produced using microbial enzymes. Apart from the anti-obesity and anti-hyperglycaemic activities of d-allulose, effects of these sugars on lipid metabolism have not been investigated. Therefore, we aimed to determine if and how d-tagatose and d-sorbose modulate lipid metabolism in rats. After feeding these rare sugars to rats, parameters on lipid metabolism were determined. No diet-related effects were observed on body weight and food intake. Hepatic lipogenic enzyme activity was lowered by d-allulose and d-sorbose but increased by d-tagatose. Faecal fatty acid excretion was non-significantly decreased by d-allulose, but significantly increased by d-sorbose without affecting faecal steroid excretion. A trend toward reduced adipose tissue weight was observed in groups fed rare sugars. Serum adiponectin levels were decreased by d-sorbose relative to the control. Gene expression of cholesterol metabolism-related liver proteins tended to be down-regulated by d-allulose and d-sorbose but not by d-tagatose. In the small intestine, SR-B1 mRNA expression was suppressed by d-sorbose. Lipid metabolism in rats varies with rare sugars. Application of rare sugars to functional foods for healthy body weight maintenance requires further studies. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    This paper presents a three-level ac-dc-ac Z-source converter with output voltage buck-boost capability. The converter is implemented by connecting a low-cost front-end diode rectifier to a neutral-point-clamped inverter through a single X-shaped LC impedance network. The inverter is controlled...... to switch with a three-level output voltage, where the middle neutral potential is uniquely tapped from the star-point of a wye-connected capacitive filter placed before the front-end diode rectifier for input current filtering. Through careful control, the resulting converter can produce the correct volt...
