  • Time :

Abstract:
This study reports on 3-dimensional (3D) imaging technologies that reconstruct the shape of both live cattle and beef carcasses. The 3D imaging technology for live cattle assesses hip height (cm), fat depth (mm) and muscle score and for beef carcasses assesses lean meat yield (%). A supervised machine learning approach using non-linear regression algorithms have been developed to assess the traits on both live cattle and carcasses. To develop the algorithms observed values are compared with the 3D assessments. The observed live cattle assessments are measured hip height, ultrasound scanning of fat depth and objective assessment of muscle score by accredited assessors; and the observed carcass assessment is computed tomography (CT) scanning of boned out primals to estimate lean and fat tissue. Cognitive perception of humans supports the view that assessors leverage shape rather than distance (e.g., when ascertaining a visual muscle score of beef cattle). Therefore, it is advantageous to represent the body shape beyond 2D and leverage 3D shape representations as curvature, which is one of the core novelties of the research. An example of predicting carcass traits from live cattle assessments before slaughter will be presented.

  • Title:Interactions Between Fish Skin Gelatin and Pea Protein at the Air-Water Interface After Ultrasound Treatment
  • Time :

Abstract:

Proteins are widely used in the food industry since they are the essential building component of many food structures i.e. emulsion, foam,and hydrogel.In the last years, a global trend towards environmentally friendly proteins, such as plant-based proteins and protein from marine byproducts is observed. This study aims to explore the foaming properties of fish skin gelatin (FG) and pea protein (PP) at pH 7 after ultrasound treatment. Foams were prepared at different ratios FG:PP (100:0 – 50:50 – 0:100) by ultrasound treatment followed by mechanical stirring. The physical stability of foam was explored by visual analysis and by Turbiscan®, the interfacial properties by pendant drop and rheological approach whereas the presence of the protein on the O/W interface was investigated by confocal laser scanning microscopy. Globally, we observed that pea proteins give more stability to the foam, by playing a major role at the air-water
interface. The possible future applications, as well as the importance of this new mixed system to tailor new materials in the food industry, are discussed in the last part.

  • Title:Non-Enzymatic Sensors for Glucose Determination in Bio-Fermentation Processes
  • Time :

Abstract:

Over the past few years, the glucose monitoring has been of great interest for clinical diagnosis, food analysis, personal care and control of bioprocesses. Enzymes-based biosensors well meet the requirements of good selectivity and high sensitivity, but the drawbacks arising from their thermal/chemical instabilities and the complex fabrication procedures have hindered their further progress for continuous monitoring. Non-enzymatic glucose sensor functioning is based on direct oxidation of glucose, where the key factor is the electrocatalytic activity of the electrode material which affects their sensitivity and selectivity. It is possible to achieve the enzymeless electro-oxidation of glucose with some transition metal-based catalysts. Among several catalysts so far proposed, electrochemical glucose sensors based on CuO, and Cu2O nanoparticles, offer many advantages compared to enzyme-based glucose sensors, and can also be less expensive compared with the ones based on noble metal nanoparticles. Copper-based sensors show a low detection limit, quick and reproducible amperometric response, as well as a wide linear range and low overpotential, due to their great ability to perform electron-transfer reactions. Here, we present a study focused on the synthesis of a new electrocatalytic material based on CuO and Cu2O nanostructures modified screen printed carbon working electrodes, prepared by an easy and cheap wet precipitation method, and to optimization of its electrochemical properties towards the glucose oxidation. The proposed sensors should have advantages such as low cost, simplicity, high stability, reproducibility and good selectivity for the detection of glucose in many application fields such as in clinical diagnostics and in biomass fermentation processes.

Abstract:

This study aims to apply a current progress on the construction and sense of carbon paste sensors based on carbon nanotubes (CNTs)/ TiO2 nanocomposite for verapamil hydrochloride determination. The role affecting the behavior of ionophore, lipophilic anionic additive as well as plasticizer is discussed carefully. The developed sensors were abbreviated as β-CDCPE and VER-PTCPE. These sensors exhibited excellent Nernstian behavior with linear dynamic ranges of 6.2 × 10-7 – 1.0 × 10-2 and 7.4 × 10-7 – 1.0 × 10-2 mol L-1, detection limits 2.0 × 10-7 and 3.5 × 10-7 mol L-1 and quantification limits 6.6 × 10-7 and 1.1 × 10-6 mol L-1 for β-CDCPE and VER-PTCPE, respectively. The investigated sensors showed adequate selectivity toward the target ion against some inorganic cations, neutral species and Diltiazem hydrochloride (drug with similar structure). The proposed potentiometric sensors were successfully performed for drug determination in pharmaceutical products, spiked surface water and human urine samples with good recovery data (98.46 and 99.06) for β-CDCPE and VER-PTCPE, respectively.

  • Title:Microencapsulation Efficiency and Gastrointestinal Release of EPA and DHA as Affected by the Wall Material.
  • Time :

Abstract:

Two types of fish oil microcapsules (monolayered (MO) and multilayered (MU)) have been developed for enriching meat products in omega-3 fatty acids, differing in the covering layer: maltodextrine and chitosan+maltodextrine, respectively, for MO and MU. In the present study, the influence of the covering layer on the efficiency to encapsulate omega-3 fatty acids, and the release of eicosapentaenoic (C20:5 n-3, EPA) and docosahexaenoic acids (C22:6 n-3, DHA) during the gastrointestinal tract has been evaluated. The microencapsulation efficiency of fish oil (percentage of encapsulated oil in relation to total oil in microcapsules) was higher for MO (88.88 ± 0.46%) than MU (55.43 ± 4.60), which may be ascribed to the loss of part of the oil during the formation of the multilayer structure in the spray-drying process. Nevertheless, the fat percentage (7-9%) and the quantities of EPA+DHA (12-13.50 mg/g microcapsule) were similar in MO and MU. This is due to a higher percentage of external oil in MU than in MO. Regarding the results on the in vitro digestion analysis of MO and MU, the quantities of EPA+DHA released at the end of oral and gastric phases were higher in MO (2.52 and 1.00 mg/g microcapsule) than in MU (1.34 and 0.71 mg/g microcapsule), while at the end of the intestinal phase the release of these fatty acids was higher in MU than in MO (10.68 and 8.76 mg/g microcapsule), indicating a probable major bioaccesibility of EPA+DHA with MU. These results may indicate the influence of the covering layer of the fish oil microcapsules on the microencapsulation efficiency and gastrointestinal release of the encapsulated omega-3 fatty acids, pointing out a major resistance of the multilayer structure of chitosan-maltodextrine to the gastric conditions despite its less microencapsulation efficiency.

  • Time :

Abstract:

Pica is the Latin of the word “magpie”, a bird species that can eat many foods that are not highly nutritional in nature. Like this bird, according to DSM-5, people diagnosed with Pica also exhibit behavior of consuming non-nutritional foods such as clay, paper clips, soil, soap, coins, ice, hair, ash, chalk, paper, feces, paint crumbs for more than 1 month. Apart from the popular eating disorders like anorexia nervosa and bulimia ner- vosa, patients with diagnosed with PICA, tend to hide their eating behaviours so it can easily be overlooked by health care professionals.

  • Title:Association of Beverage Consumption Types with Weight, Height, and Body Mass Index in Grade 3 Children in Northern Taiwan: a Cross-Sectional Study
  • Time :

Abstract:
Background:
The increasing prevalence of convenience and beverage stores in Taiwan provides an environment for children to access different beverages types. To our knowledge, the relationship between beverage consumption types and anthropometrics in children has not been reported in Taiwan. This study aims to examine the association of consumption frequency of beverage types that children commonly drank with anthropometrics in grade 3 children in Northern Taiwan.
Methods:
A cross-sectional study was conducted in Taiwanese third grade students to examine the association between the consumption frequency of beverage type and anthropometrics. Samples were collected from 10 Northern Taiwan elementary schools. Parents of the 515 children completed a questionnaire with written instructions voluntarily, which was designed to collect demographics, frequency of consumed beverage types, and anthropometrics. This study is novel because beverage types were categorized based on sugar and protein contents, namely nutritious (N), sugar (S), nutritious and sugar (NS), and non-nutritious and sugar-free (NS-free). The differences in height and body weight between intake frequencies within each beverage type were determined using analysis of variance (ANOVA) test or nonparametric statistics, dependent on the confirmation of normal data distribution.
Results:
Height and weight of children consuming the most N beverages fell in the highest respective percentile compared to those who did not consume them (p values P = 0.001 and 0.035, respectively). Consumption of NS and S beverages were not associated with height, body weight, and body mass index (BMI). Children who consumed more NS-free beverages were significantly heavier (p = 0.016) and had a larger BMI (p = 0.001).
Conclusion:
This is the first study conducted on third-grade children in Taiwan showing that beverage consumption type was associated with anthropometrics. In conclusion, nutritious beverages appear to be a better choice in terms of growth in children. Nevertheless, additional related studies, including an overall assessment of children’s calorie and nutrient intakes and related dietary behaviors, are warranted to provide more helpful information for policymakers.

  • Time :

Abstract

The worldwide concerns and heightened sensitivity to the emerging drug-resistant superbugs have energized scientists to search for new alternatives for in-feed antibiotic growth promotor. Powered by consumer demand for natural products and due to their beneficial effects on growth performances, phytogenics became very popular and favorable alternatives. Yet, their mode of action was not fully defined. Here, we showed that supplementation of phytogenics in water or in feed improves
feed efficiency in broilers and modulates hypothalamic and peripheral metabolic pathways (reduction of hepatic fatty acid synthesis, mobilization of fat store, and enhancement of muscle protein synthesis), which might explain, at least partly, their effect on feed efficiency improvement in broilers.

  • Title: Fermented Brown Rice and Rice Bran Delayed Onset of Spontaneous Type 1 Diabetes in NOD Mice
  • Time :

Abstract:

Brown rice and rice bran fermented by Aspergillus oryzae (FBRA) is a processed food that is rich in partially digested fiber, rice bran-derived phytic acid, and plant polyphenols. Its anti-inflammatory effects have been reported in several animal disease models. Type 1 diabetes is an autoimmune disease caused by Th1-mediating immune attack for pancreatic islets including cytokine-mediated production of reactive oxygen species (ROS). Chronic pancreatic inflammation induces death of islet  cells and depletes insulin secretion, resulting in onset of diabetes. In addition to genetic and immunologic factors, environmental factors such as infection, diet and microbiota can also contribute to the pathogenesis. Possible targets of functional food in this type 1 diabetes include: 1) islet-specific T lymphocyte activation; 2) islet-targeting lymphocyte infiltration; 3) cytokine-mediated inflammation or ROS production; 4) regeneration of damaged islets or apoptotic cell death of damaged islets. Here, I will introduce our recent work showing the suppressive effects of dietary administration of FBRA against spontaneous onset of type1 diabetes in NOD female mice. While control diet-fed mice showed glucosuria and hyperglycemia at around 20 week of age, dietary administration of 0.5% FBRA significantly delayed the onset of these diabetic features. The FBRA-fed group at 30 weeks of age kept higher ratio of intact islets and showed significantly lower insulitis score compared to the control diet group, with dose-dependency from 0.25% to 0.5% dietary concentration of FBRA. These results suggest that dietary FBRA delayed the spontaneous onset of diabetes in NOD mice probably through maintaining the number of intact islets. How do the FBRA or its components affect the process of diabetes is still unclear, examined results of FBRA on the T cell population and the expression of Pdx1 and related molecules which are known to involve islet cell viability, death, and regeneration, will be discussed.

  • Title:Changes in Nutrient Absorption in children and Adolescents Caused by Fructans, Especially Fructooligosaccharides and Inulin
  • Time :

Abstract:

Introduction
Fructans, such as inulin and fructooligosaccharides (FOS), have several effects on human health owing to their prebiotic character, including anti-microbial and anti cancer effects, and to their influence on the absorption of minerals, which is very important in childhood and adolescence.

Objective
Our aim was to review the role of some fructans in the absorption of vitamins and minerals in children and adolescents.

Methods
We conducted a narrative review of the absorption of nutrients with fructans. We collected quantitative data for our thematic analysis, which was performed using the electronic databases Medline, Lilacs, Web of Science, and Scopus from January 2000 and January 2019. This review comprises a total of 10 articles.

Results
Few studies were found regarding the use of prebiotics and nutrient absorption in children. Studies on calcium, iron, magnesium, and vitamin D were the most prevalent.Some studies reported that FOS appears to increase calcium uptake in the gut and stimulates the growth of bifidobacterium in the colon, reducing iron intake by enteric pathogens, and increasing the absorption of these minerals. Others reported an improvement in the absorption of vitamin D and E with inulin.

Conclusion
Consumption of fructans improves the health of the microbiota, altering the absorption of some nutrients.

  • Title:Mustard Grains, Germination, Phenolic Compounds and Antioxidants: How Can They Interact?
  • Time :

Abstract:

Mustard grains are known for centuries as an important commercially condiment in all of the world with a huge variety of use and applications. Our research group has been studying this promising grain to improve its biological properties. To begin, choosing the best solvent combination to recover phenolic compounds with antioxidant activity potential was encouraged. We reported for the first time an optimization study for recovery of phenolic compounds from mustard grains in order to obtain extracts with better antioxidant properties. Continuing studies, germination was chosen as a natural process due the actual tendency to valorize the spontaneous process and knowing that the germination is an efficient and economical process that promotes dynamic and complex positive changes in bioactive compounds and nutritional quality of grains. The main questions raised in our research were: How could we germinate mustard grains since changes during the process are peculiar for each grain? How germination affects the antioxidant potential and phenolic compounds composition? So, the first step was to analyze different germination parameters correlated with antioxidant potential. Also, to better understand those complex transformations, our research group investigate how the variation of free and insoluble-bound phenolics affected the antioxidant properties of mustard grains when submitted to different germination parameters. The identification of the bioactive compounds by chromatography techniques was also important to the final discussion. Given the positive results obtained, we can conclude that germinated mustard grains have the potential for application as a functional and nutraceutical food.

  • Title:Expanding the Toolbox for Food Microbiologists with New Stable Fluorescent Laboratory Control Strains
  • Time :

Abstract:

Bacterial control strains are a critical component in microbiological methods, ensuring the media, reagents and related components of a test method are performing in a manner to ensure the quality of the analytical results. The use of naturally occurring bacterial strains as positive controls during testing is counter-indicated due to the risk of sample cross-contamination. Taking advantage of the target site specificity of transposon Tn7, we developed a collection of strains which express Green Fluorescent Protein (GFP) at high-levels, permitting the rapid screening of the following species on selective or non-selective agar plates: Escherichia coli O157:H7, Shigella sonnei, S. flexneri, Salmonella enterica subsp. enterica serovar Gaminara, S. Mbandaka, S. Tennessee, S. Minnesota, S. Senftenberg and S. Typhimurium. These new engineered strains that fluoresce when irradiated with Ultraviolet light, are easily identified and differentiated from naturally occurring pathogens. Importantly, performance testing in our laboratory and several FDA field laboratories showed that none of those strains containing the GFP marker displayed the potential of becoming a mixed population of fluorescent and non-fluorescent cells, making them suitable laboratory control strains for food microbiologists. We are employing the same approach to engineer additional reference strains for the FDAs’ Compendium of Microbiological Methods, the Bacteriological Analytical Manual (BAM), to exhibit the same stable fluorescent phenotype. Having a suite of control strains with stable, easily identifiable phenotypes like fluorescence eliminates the need to perform the time consuming and expensive confirmatory testing required when naturally occurring bacterial strains are used in microbial methods.

  • Time :

Abstract:

Psyllium has been used worldwide to improve the symptoms of constipation, irritable bowel syndrome and diarrhea. It has been recognized as a cholesterol-lowering agent to be used in the treatment of hypercholesterolemia. Given psyllium’s ability to reduce low-density lipoprotein (LDL) cholesterol levels, the National Health Surveillance Agency (ANVISA) and the Food and Drug Administration (FDA) authorize manufacturers of food products to include health claims for psyllium on their labels, provided that these products contain the minimum amount (content) of the referred fiber required for health claims on their labels. Health claims add value to products, making them competitive, and are used by marketing departments to arouse consumers’ attention and influence their buying decisions.
In addition to offering fibers to the consumer, products that contain psyllium also include health claims on their labels, which is an important marketing advantage, since most consumers seek food products with functional properties. Psyllium also contains antioxidant compounds (phenolics and flavonoids), and the frequent intake of this fiber contributes to the reduction of fasting and postprandial blood glucose concentrations, causes satiety, reduces hunger and the urge to eat. It also assists in weight loss.
Due to the benefits of this fiber, several studies have investigated the incorporation of psyllium into bakery and dairy products.

  • Title:Research for Behavior Evolution Pattern of Diseased Shrimp Based on Improved ResNet-50 Convolutional Neural Networks
  • Time :

Abstract:

Such huge amount of defective and diseased shrimp exists in the crowded shrimp clusters after harvest. To ensure the quality of fresh shrimp and safety of the eaters, it is necessary to remove these impurities in time. The process was completed traditionally by using machine vision technology, our team published many related papers and developed an on-line shrimp inspection machine which has been put into application in the Xiaoshan shrimp processing factory. However, shrimp has a long growth cycle, which stage does the diseased shrimp produce or what is the relationship between the shrimp behavior and the final quality of shrimp? The problem is fantastic and deserved to study from the perspective of fundamental research and shrimp abnormal behavior evolution pattern. To this end, the shrimp abnormal behavior evolution pattern was studied with diseased shrimp. Firstly, the underwater machine vision system was constructed based on shrimp breeding environment and shrimp behavior, including high-performance computer, high resolution camera, waterproof LED light source, underwater sensors. Secondly, the behavior of shrimp body was monitored within 24 hours a day respectively under infecting of nine virus types, including TSV、WSSV、SHIV、YHV、IMNV、CMNV、MBVD、HPV、BMNV. Then, correspondingly snap 30 days video of shrimp behavior independently, saved these videos and made some video processing jobs. Traditional ResNet-50 convolution neural network was improved, the soft-Max layer is modified and delete all connection layers. Treat the last convolution and pooling layer as a final layer and thus construct a visual feature extraction, which is used to display the visualization results, make it adapted to the special shrimp appearance characteristics. Finally, through experimental verification, under the nine types of virus, the movement observation respectively of 100 shrimp was snapped, we divided them into ten groups, each group recorded 10 section 20 min video. The shrimp behavior all show some abnormal performance with the infection of virus, and the degree of abnormal behavior that increases with the rising of concentration. The proposed CNN can build a model to learn the correlation between shrimp behavior and quality of shrimp. This experiment also confirmed all the shrimp infected with virus, would undermine the shrimp body immune system and lead to shrimp irreversible damage to the nervous system, resulting in the growth process of shrimp to produce abnormal behavior mode. Experiment results showed that the appearance color of some infected shrimp are more noticeable, and some in the abdominal muscle texture produce evident in the evolution. The results confirmed that infected shrimp show some abnormal behavior. Moreover, the evolution rule of shrimp abnormal behavior is clear along with the deepen of ResNet, which also related to the final quality of harvested shrimp, leading to such huge amount of diseased shrimp. This will pose a great threat to the life and safety of those who eat it.

  • Title:Multidisciplinary Approach to Obesity: Aerobic or Resistance Physical Exercise?
  • Time :

Abstract:

An integrated treatment based on dieting, physical training and cognitive-behavioural psychotherapy is an effective tool to reduce obesity and its consequences. However, the feasibility of this approach is problematic. This study aims to compare two multidisciplinary programs used to improve weight loss. Fifty-two obese individuals were subjected to an Enhanced Lifestyle Counselling associated with, according to their own choice, dieting (N =11), or dieting þ aerobic training (n = 18), or dieting þ resistance training program (n = 23). The study experiment spanned 16 weeks divided into two phases. The first phase lasted 04 weeks and was oriented to enhance motivation and establishing changes in behaviours related to dietary and sedentary lifestyle. The second phase lasted 12 weeks and was oriented to add aerobic or resistance training. Body compositions, cardiovascular disease risk factors, and cardio-respiratory fitness were assessed. Data demonstrated that all obesity treatment programs were able to improve all studied variables. Weight loss levels were -6.03 ± 2.08, -10.5 ± 2.33, and -9.37 ± 1.99 kg in Dieting, DAT and DRT groups, respectively. Our results noted also that exercise training could play an important role in reducing obesity and its consequences. Nevertheless, modifications were more important in DRT at the explosivity and muscle strength and in DAT at fat percentage, aerobic capacity, SA, and CVR factors. Conclusion: The current evidence noted that both multidisciplinary weight loss programs were efficient in the treatment of obesity and its comorbidity. Moreover, the use of aerobic exercises was more effective in reducing body fat and improving cardiorespiratory fitness. However, using resistance exercises appeared to be more appropriate to enhance the muscle potential.

  • Time :

Abstract:

The analysis of different types of feed for feeding various farm animals from the point of view of their chemical safety was carried out. It has been established that the most toxic feed among farm animals is included in the diet of beef and dairy cattle. Thus, the main reasons why the World Health Organization at one time evaluated red meat as a possible carcinogen for humans become apparent. Among the toxic impurities in the feed for these two groups of animals, mycotoxins, especially lipophilic ones as well as polyaromatic hydrocarbons (PAHs) and persistent organic pollutants (POPs), pose the greatest danger. These substances pose a threat to animal health andnproductivity, are capable of being accumulated and transferred to animal products and thus can be incorporated into human food chains. A comparative analysis of the sorption capacity of feed adsorbents of different nature and polarity with respect to lipophilic sorbates was carried out. Examples of effective removal of POPs from dairy and meat products in cattle herds are given. The strategy and tactics of using cost-efficient non-polar adsorbents to protect the digestive tract of farm animals and, indirectly, human health from the harmful effects of lipophilic toxins from feed for farm animals are discussed.

  • Time :

Abstract:

The use of firewood is an old tradition in Brazil. In the south and southeast regions,firewood is used by customs and due to the colder climate. On the other hand, the northern and northeastern regions use firewood for economic reasons. Many people use it because they believe that firewood makes food tastier. Others because the wood stove brings people closer. However, throughout the country firewood or charcoal is used in the preparation of the barbecue. This type of food is most common on weekends and parties. The stoves and barbecues used are the most varied, from very simple to the most sophisticated. As well as firewood, which comes from both deforestation and reforestation. Firewood characteristics, per capita consumption, and distribution percentage vary widely within the country. Although LPG is the most used fuel in Brazil, a significant portion of the population, about 11 million households use firewood. This study will present and explore the data regarding the use of firewood for cooking.

  • Title:Trends in Sugar-Sweetened Beverages: Are Public Health and the Market Aligned or in Conflict?
  • Time :

Abstract:

The adverse effect of consuming sugar-sweetened beverages on the risk for developing obesity has been cited as an example of market failure, justifying government intervention in the marketplace, usually in the form of taxation. Food and beverage producers typically resist regulation putting them in conflict with public health advocates. In Australia, a recent analysis of market research data has shown that per capita volume sales of sugar-sweetened beverages have been declining for at least 22 years. Consequently, the per capita contribution of sugar-sweetened beverages to the sugar content of the national diet has fallen by nearly 30 per cent. Per capita volume sales of non-sugar-sweetened beverages have increased over this period, especially those of bottled water which have increased exponentially over the last decade. Volume sales of non-sugar-sweetened beverages have exceeded those of sugar-sweetened beverages in Australia since 2015. These significant changes in the pattern of beverage sales are consistent with obesity prevention recommendations but have occurred in the absence of significant government regulation. Rather, they appear to reflect market forces at work. Contrary to the market failure argument that consumers fail to appreciate the links between their choice of beverage and its health consequences, changes taking place in the beverage market appear to be driven by consumer interest in health and wellness. Thus, the public health challenge in relation to sugar-sweetened beverages may have less to do with regulating the market and more to do with harnessing it.

  • Title:Chrysin Mitigated Obesity by Regulating Energy Intake and Expenditure in Rats
  • Time :

Abstract:

Obesity is characterized by an imbalance between energy intake and energy expenditure. Chrysin is a flavonoid found in plant extracts from Passiflora family, honey and propolis. Molecular modeling studies were carried out to determine the binding potential of chrysin to pancreatic lipase (PL). Further, the kinetics of inhibition of PL and effect of chrysin on the absorption of fats and sucrose preference test was studied in normal rats. Obesity was induced in the rats by feeding of high fructose diet (HFD) for 16 weeks. The rats were divided into six groups: normal control, HFD control, orlistat and three doses of chrysin (25, 50 and 100 mg/kg body weight). Body weight, body mass index (BMI), abdominal circumference-thoracic circumference (AC/TC) ratio, calorie intake, adiposity index, fecal cholesterol, locomotor activity and histopathology of the adipose tissue of the rats were determined. The docking score of chrysin to PL was found to be -8.03. Chrysin inhibited PL competitively (IC50= 0.018±0.006 mM). It significantly reduced the absorption of fats and sucrose preference in rats. Chrysin significantly decreased the body weight, BMI, AC/TC ratio, adiposity index, calorie intake and significantly increased the fecal cholesterol excretion of rats. Chrysin significantly increased the locomotor activity of rats in a dose-dependent manner. The histopathological examination of the adipose tissue revealed reduced hypertrophy of adipocytes in rats treated with chrysin when compared with HFD control. Thus, chrysin seems to be a promising molecule to combat obesity by inhibiting pancreatic lipase, reducing bingeing on sugars and increasing the locomotor activity of rats.

  • Title:The Role of New Antioxidant Milk-Derived Bioactive Peptides in Nrf2 Activation
  • Time :

Abstract:

Milk-derived bioactive peptides can improve the treatment of many diseases, behaving as antihypertensive, antimicrobic and antioxidant agents. This study was focused on new peptides evaluated for their antioxidant properties and mechanism of action cell enviroment. Peptide enriched fractions were extracted from fermented milk and purified in order to obtain the sequence of the included bioactive peptides. Twenty-three new peptides were identified and synthesized by solid phase procedure. Their antioxidant properties were analysed in vitro and in a cellular model using Caco-2 cells. Among these peptides, N-15-M, E-11-F, Q-14-R and A-17-E were selected in order to estimate their antioxidant capacity on Caco-2 cells both as protection against oxidative stress and inhibition of ROS production induced by TbOOH. In order to understand the possible action of the peptides on Keap1-Nrf2 pathway, which is involved in the response to oxidative stress, the translocation of Nrf2 from cytosol to the nucleus was taken into account. N-15-M, Q-14-R and A17-E were able to activate the Keap1-Nrf2 system, as shown by the higher amount of Nrf2 found in the nucleus with respect to the control. This modulation led to overexpression and increase of activity of antioxidant enzymes such as TrxR1, GR, NQO1 and SOD1. The interaction of these peptides with Keap1 was also studied through molecular docking analysis. The results confirmed that N-15-M, Q14-R and A-17-E interact with the residues of the Keap1 pocket involved in the binding with Nrf2, acting as disruptor of Keap1-Nrf2 interaction.

Abstract:

Enzymatic reactions refer to organic reactions catalyzed by enzymes. This review aims to enrich the documentation relative to enzymatic reactions occurring during the anaerobic degradation of residual organic substances with emphasis on the structures of organic compounds and reaction mechanisms. This allows to understand the displacement of electrons between electron-rich and electron-poor entities to form new bonds in products. The detailed mechanisms of enzymatic reactions relative to the production of biomethane have not yet been reviewed in the scientific literature. Hence, this review is novel and timely as it discusses the chemical behavior or the reactivity of different functional groups, thereby allowing to better understand the enzymatic catalysis in the transformations of residual proteins, carbohydrates, and lipids into biomethane and fertilizers. Such understanding allows to improve the overall biomethanation efficiency in industrial applications.

  • Time :

Abstract:

Anthocyanins (ACNs) are water soluble natural pigments, which not only impart color to the foods, also exhibit multiple healthy effects. Black soybean (Glycine max (L.) Merr.) have been used as nutritionally rich food and folk medicine and its seed coat contains abundant levels of anthocyanins (mainly cyanidin-3-O-glucoside; Cy3G). In order to illustrate the hypoglycemic mechanism of the dietary anthocyanins from black soybean, the effects of black soybean seed coat extract (BSSCE) and cyanidin-3-O-glucoside (Cy3G), he major anthocyanins of BSSCE on regulation of Akt and GLUT4 in L6 rat skeletal muscle cells were studied. BSSCE and Cy3G significantly augmented the glucose uptake in L6 myotubes in comparison to the normal control (p < 0.05). Especially, at 150 μg/mL ofBSSCE and40 μMofCy3G treatment, the2-NBDG uptake level were increased by 1.81fold and 1.90-fold with that of normal control, respectively. Furthermore, the expressions of p-Akt and GLUT4 were also increased and theGLUT4 translocation was promoted by BSSCE and Cy3G, which indicated the involvement of the Akt/GLUT4 signal pathway in the hypoglycemic mechanism ofBSSCE. Overall findings revealed that Cy3G enriched BSSCE might be a promising functional food or medicine for the treatment of T2DM and its associated metabolic disorder. Biography:

  • Title:Bioactivity of Anthocyanins and Their Stability as Natural Food Colorants: The Case of Pomegranate Juice
  • Time :

Abstract:

The widespread use of pomegranate juice (PJ) is due not only to its health benefits, which originate to its flavonoid content, but also to its bright red color. Anthocyanins (ΑCNs) are the chemical group mainly responsible for both functions that unlike other flavonoids, are characterized by rearrangements in response to pH changes. The great benefit in the human diet is originated from the fact that they can be absorbed as intact molecules without undergoing metabolic changes.
The role of ACNs as food coloring agents has drawn great interest in exploring natural food colorants as a promising alternative to synthetic food dyes. Recently, synthetic food dyes attracted public concerns regarding their potential impact on human health, specifically neurological and behavioral functions. So far, ACNs use as food colourants has been limited due to their low stability, which can be influenced by several factors such as their structure, pH, temperature, light, copigments, metal ions, enzymes, oxygen, ascorbic acid and sugars, among others. The copigmentation is one of the most important factors influencing plant pigmentation in vivo. It causes stabilization of the coloured anthocyanin structural forms and consequently enhances their colour. Co-pigments are colourless on their own, but when added to anthocyanin solution, they increase the colour intensity and the stability of the solution. Therefore the exploitation of co-pigments impact on ACNs stability in food systems, is of great interest for the food industry and the consumers.

  • Time :

Abstract:

Obesity (OB), considered as one of the Non-Transmissible Chronic Diseases, has as its fundamental characteristics that of being prevalent at a global level, increasing in number, affecting developed and developing countries, affecting both genders, and all ages and social groups.
Objective: To identify if high birth weight is a predictive factor (risk factor) for abdominal obesity in children 7 to 11 years old, and its relationship to gender, age and diet. Method: A case-control descriptive study was carried out with children born between January 1992 and December 1995, in order to identify early risk factors (atherosclerotic accelerators) such as abdominal obesity in children aged 7 to 11, and who have a history of macrosomia or high birth weight, as well as their relationship with gender, age and diet.
Results: It was observed that the waist/height value was normal in 60.8% of the study group and in 64.00% in the control group. The difference between groups, gender, and age was not significant (P=.6859). As regards the diet in the study group (macrosomic), there was no significant association between the type of diet and waist circumference/height values, with an_ 2=0.223 and P=.6373 (not significant). In the control group (with normal weight at birth), it was found that there is a significant statistical association between the type of diet and waist circumference/height values. This means that it can be stated, with 95% reliability, that the type of diet is associated with waist/height values.
Conclusions: High birth weight is not a predictive factor (risk factor) for abdominal obesity (increased waist/height index). Gender and age are independent for abdominal obesity (macrosomic and normal weight at birth). The diet in high birth weight children is not related to the index waist-height index, which is not the case in those born with normal weight under the same conditions. The marked increase in abdominal obesity (Waist/height index) in children between 7 and 11 years old in both groups is worrying.

Abstract:

Brucellosis is one of the most common zoonoses, which affects multiple species. Brucella suis is responsible for a substantial proportion of infections in humans. The B. suis biovar 1 infection in cattle is an emerging veterinary an public health problem. Little is known about the presence of B. suis in wild fauna. In Argentina seroprevalence of Brucella sp was reported in fox (Lycalopex gymnocercus), wild boar (Sus scrofa), European hare (Lepus europaeus), armadillos (Chaetophractus villosus) in Buenos Aires, La Pampa and Patagonia province. Brucella suis biotype 1 was isolated from hare in Buenos Aires and La Pampa. It has also been isolated from armadillos in La Pampa. Hares infected with B. suis biovar 1 exhibited typical lesions of the disease. Nevertheless armadillos have not macroscopically observable lesions. However, histology revealed small internal abscesses (1 mm) in the parenchyma of liver and spleen. Under experimental conditions Brucella was isolated from the spleen, liver, mesenteric lymph node, uterus, urine and testicles samples. In Argentina, as in many countries, there are an underestimation and a sub notification of human cases of brucellosis. From 2009 to 2011, 1040 sera from human resulted positive by serology to brucellosis. Blood cultures were perform in some patients, being able to isolate B. suis biovar 1 in 53% of them and B. abortus in 27%. Although the source of infection is unknown in all of these cases. In rural areas armadillos and hare are hunted and consumed, by humans. However until now it is not available evidence indicating that armadillos and hare can transmit brucellosis to domestic animals, humans or other wildlife by direct contact The route of transmission to humans could be the ingestion of contaminated food, products or undercooked meat or by manipulating these animals at the time of extracting their skin and offal. Only careful and systematic monitoring will help to know the impact of wild animals on the transmission of this zoonotic disease.

Abstract:

Two-dimensional hybrid carbon nanosheets were synthesized and functionalized with various functional groups, which feasible produced unique thermal, mechanical, optical, and electrical properties. The lower generation (between G1 and G3) polyamidoamine (PAMAM) dendrimer was covalent functionalized to reduced graphene oxide through conventional chemical methods. The covalent layer by layer assemble with mercaptopropionic acid (MPA), PAMAM dendrimer and gold nanoparticles (AuNPs) on Au transducer consists of an inexpensive and straightforward strategy of developing a highly ordered multilayer three-dimensional (3D) open and fractal nanoarchitecture as a fast, ultra-trace determination of label-free DNA hybridization sensing[1]. Keen selections of AuNPs were encapsulated onto the PAMAM G1 functionalized on graphene oxide (GG1PD), by strong physicochemical interaction between AuNPs and -OH of rGO in GG1PD. Their morphologies, structures, electrochemical properties, and gene nanobiosensing performances were characterized and evaluated. AuNPs/GG2PD based probe displayed the best structural stability, lowest mobility on a solid surface with an increasing charge resistance, widest linear range (1.1×10−6 to 1×10−18 M), and the lowest limit of detection (1.87×10−19 M) in comparison with both AuNPs/GG1PD-based and AuNPs/GG3PD-based probes[2]. This work will provide a new candidate for the development of metal nanoparticles functionalized dendrimers with inorganic nonmetallic nanomaterials as cores with 3D fractal nanoarchitecture and promising electrochemical gene nanobiosensing platforms based on dendrimer-nano inorganic hybrids with 3D nanoarchitectures and LBL assembly for fast and ultra-trace detection of label-free DNA hybridization with potential application in bioanalysis and medical diagnosis of genetic disease.

  • Title:Preparation of Corn Stover Nanocellulose and Properties Characterization Using Transmission Electron Microscopy (TEM), Instron Mechanical Measurements, Rheometry, and Diffusing Wave Spectroscopy (DWS)
  • Time :

Abstract:

Agricultural waste corn stover has very little value but can be good renewable, biodegradable, and inexpensive source to produce value-added products such as cellulose and nanocellulose. Cellulose was extracted from corn stover by the processes of alkali treatment and delignification, resulting in a >93% purity. The particle size of the extracted cellulose was reduced by mechanical shearing through high pressure homogenization. When passing through a homogenizer thirty times, the cellulose nanofibril (CNF) can be obtained. The diameters of the CNF ranged between 5 – 50 nm, and the lengths were microns. The mechanical properties of the films, made by corn stover cellulose, with and without high pressure homogenization shearing were evaluated using an Instron instrument. The films made by cellulose without shearing exhibited weaker mechanical properties, while the CNF films exhibited stronger mechanical properties. The linear rheological properties of CNF suspensions were investigated using mechanical rheometry and results show solid-like viscoelastic behavior. The microrheology of corn stover CNF suspensions was investigated by the novel technique diffusion wave spectroscopy (DWS) and compared with mechanical rheometry measuremants. DWS microrheology measurements were in excellent agreement with the conventional mechanical rheological studies for corn stover CNF. By comparing the mean-square displacement (MSD) of the microbeads embedded in five concentrations of corn stover CNF, we found that the suspensions exhibited slight heterogeneity behavior at the lower concentration of 0.25%, while the material displayed a definite degree of heterogeneity at higher concentrations. The magnitude of high-frequency viscoelastic moduli (|G*(ω)|) for the corn stover CNF is proportional to the 3/4 power of the frequency (ω), which is the semi- flexible polymer behavior. The identified properties of the corn stover CNF will provide us the useful information for utilizing this kind of nanocellulose.

  • Title:Hypoglycemic and Anti-Insulin Resistant Effects of Saskatoon Berry and its Active Components in Western Diet-Induced Obese and Insulin Resistance Mice and Relationship with Gut Microbiota
  • Time :

Abstract:

Diabetes becomes epidemic in worldwide countries. Nine out of ten diabetic patients are type 2 diabetes (TED). TED is characterized by insulin resistance and obesity. Uncontrolled diabetes leads serious consequences including heart attack, stroke, chronic renal failure, blindness and low limb amputation. Diabetes often requires lifetime treatment. Most of hypoglycemic medications have side effects. Natural foods or pharmaceuticals with hypoglycemic potential are expected to provide a safer management for diabetic patients. Saskatoon berry is a traditional food of First Nations people in North America, and has abundant amounts of anthologists, including cyanide-3-glucose (C3G). Our previous studies demonstrated Saskatoon berry powder (Sp) attenuated oxidation stress and inflammation, but did not alter glucose metabolism in genetic db/db diabetic mice. We recently examined the effects of SBp and C3G on glucose metabolism, insulin resistance, vascular inflammation, and intestinal microbiol in diet-induced insulin resistant mice, a model for TED. Male C57 BL/6J mice were fed control diet, high fat-high sucrose (HFHS) diet, HFHS+5% SBp (HFHS+B) or HFHS+C3G in a dosage comparable to that in 5% SBp for 12-15 weeks. The composition of bacterial community in mouse stool was characterized using the Illumine sequencing of V4 region of 16S rRNA gene. HFHS diet increased body weight, fasting plasma glucose, cholesterol, triglycerides, insulin, homeostatic model assessment-insulin resistance, monocyte adhesion, tumor necrosis factor-α, plainsmen activator inhibitor-1, monocyte chemotactic protein-1, intracellular cell adhesion molecule-1, urokinase plainsmen activator and its receptor in plasma or aortae, but not body weights, compared to the control diet. HFHS+B or HFHS+C3G diet postponed the increase in body weight, suppressed HFHS diet-induced disorders in insulin resistance, hepatic stenosis and vascular inflammation. The ratio of Firmicutes/Bactericides in the HFHS group was higher than that in the control group (p<0.01), and that in the HFHS+B or HFHS+C3G group was lower than that in the HFHS group (p<0.05). The abundances of S24-7 family bacteria negatively correlated with all tested metabolic or inflammatory variables and body weights of mice. The results suggest that Saskatoon berry and its component, C3G, are able to reduce HFHS diet-induced hyperglycemia, insulin resistance and vascular inflammation in mice with T2D. The beneficial effects of SBp and C3G may result, at least in part, from their impact on gut microbiol.

  • Title:Involvement of Neutrophils in Exercise-Induced Muscle Damage and its Prevention
  • Time :

Abstract:

Neutrophils not only play a critical role in host defense by migrating to the site of infection and producing reactive oxygen species (ROS), but also mediate pathological processes involved in tissue destruction. Therefore, it is important to assess and modulate neutrophil activities. Exhaustive exercise facilitates neutrophil activity, suggesting their involvement with muscle damage [1-4]. However, at that time, we needed to separate neutrophils from whole blood, and great care was needed to do this. Also, it took at least 1 h to adjust a fixed cell concentration of neutrophils for the functional analyses, and some researchers criticized the method, saying that the recovery rate was low and the neutrophil functions were altered from the in vivo environments. Because we observed complex phenomena centered on neutrophils following exercise, some novel technology was required to examine the neutrophil dynamics and functional modulation. Thus, I would like to share some of our research on neutrophils in relation with exercise and muscle damage. I will begin with my early studies on neutrophil functional analyses and a newly developed measurement system [5-7]. Then, some key data about effects of exercise, antioxidant modulation, mechanisms of exercise-induced muscle damage, and possible preventive countermeasures such as functional foods targeting pathogenesis will be described [7-10].

Abstract:

The use of wastewater for rearing domestic animals is a common phenomenon in most of the developing countries like Pakistan that face a serious shortage of freshwater resources. However, most of the literature has only focused on the indirect effects of wastewater use on animal health or productivity, and literature on the direct effects of wastewater use is rare. Therefore, this study aims to investigate the direct and indirect effects of wastewater usage on the prevalence of animal diseases and animal health in Pakistan. The study is based on a household-level survey of 360 domestic water buffalo herds collected from 12 districts of Punjab Province, Pakistan. We tested the prevalence of the animal’s diseases, animal’s health, and wastewater-use preference with various econometrics tools, such as the Poisson, negative binomial, and logistic regressions. The findings of the study show that the majority of the farmers use wastewater for buffalo bathing due to the shortage of freshwater resources. Results explore the prevalence of diseases such as clinical mastitis, tick infestation, and foot and mouth disease at the farm level significantly associated with buffalo bathing in the wastewater. Moreover, bathing in wastewater pre- and post-milking also plays a role in the occurrence of diseases. Particularly, if the buffalo’s access to wastewater for bathing is within 60 minutes after milking, the probability of the animals being exposed to mastitis is higher. Furthermore, on investigation, a number of factors are found, such as the distance to the water source, power shortage, groundwater availability, and the education of farmers that influence farmers’ behavior of letting their animals take a bath in wastewater. Moreover, the use of different preventive measures improves the animal health

Abstract:

Recognizing the importance of food safety education toward students and stakeholders, the Food Safety and Microbiology program at Virginia State University (VSU) works continually to improve the safety and quality of our nation’s food supply through research, teaching and outreach.
The program’s research is designed to increase knowledge of microbial ecology with regard to the routes of contamination from on-farm investigations to food distribution. The program also evaluates methods and approaches to better prevent, intervene and verify the presence of foodborne pathogens from farm to fork.Program resources are utilized to teach and train students on current and emerging food safety issues. The program provides students conventional and advanced techniques in food safety analysis, empowering them to meet global societal needs.The program works closely with Cooperative Extension specialists to benefit small-scale farmers and processors with limited resources.The program endeavors to develop a regional educational and training initiative for stakeholders on safe food production and handling.
In keeping with the vision of the program, active collaborations with intra- and extra-mural institutions and government agencies are sought to promote multidisciplinary approaches and to strengthen research and education capacity related to current and developing issues in food safety.
Therefore, this lecture will include an overview on the importance of food safety research and a summary of ongoing projects.
