Zinc deficiency is a global nutritional problem, particularly in children and women residing in settings where diets are cereal based and monotonous. It has several negative health consequences. Fortification of staple foods with zinc may be an effective strategy for preventing zinc deficiency and improving zinc-related health outcomes. To evaluate the beneficial and adverse effects of fortification of staple foods with zinc on health-related outcomes and biomarkers of zinc status in the general population. We searched the following databases in April 2015: Cochrane Central Register of Controlled Trials (CENTRAL, Issue 3 of 12, 2015, the Cochrane Library), MEDLINE & MEDLINE In Process (OVID) (1950 to 8 April 2015), EMBASE (OVID) (1974 to 8 April 2015), CINAHL (1982 to April 2015), Web of Science (1900 to 9 April 2015), BIOSIS (1969 to 9 April 2015), POPLINE (1970 to April 2015), AGRICOLA, OpenGrey, BiblioMap, and Trials Register of Promoting Health Interventions (TRoPHI), besides regional databases (April 2015) and theses. We also searched clinical trial registries (17 March 2015) and contacted relevant organisations (May 2014) in order to identify ongoing and unpublished studies. We included randomised controlled trials, randomised either at the level of the individual or cluster. We also included non-randomised trials at the level of the individual if there was a concurrent comparison group. We included non-randomised cluster trials and controlled before-after studies only if there were at least two intervention sites and two control sites. Interventions included fortification (central/industrial) of staple foods (cereal flours, edible fats, sugar, condiments, seasonings, milk and beverages) with zinc for a minimum period of two weeks. Participants were members of the general population who were over two years of age (including pregnant and lactating women) from any country. Two review authors independently assessed the eligibility of studies for inclusion

Full Text Available To study the associations between maternal consumption of non-staple food in the first trimester and risk of neural tube defects (NTDs in offspring. Data collected from a hospital-based case-control study conducted between 2006 and 2008 in Shandong/Shanxi provinces including 459 mothers with NTDs-affected births and 459 mothers without NTDs-affected births. Logistic regression models were used to examine the associations between maternal consumption of non-staple food in the first trimester and risk of NTDs in offspring. The effects were evaluated by odds ratio (OR and 95% confidence intervals (95% CIs with SAS9.1.3.software. Maternal consumption of milk, fresh fruits and nuts in the first trimester were protective factors for total NTDs. Compared with consumption frequency of ˂1 meal/week, the ORs for milk consumption frequency of 1–2, 3–6, ≥7 meals/week were 0.50 (95% CI: 0.28–0.88, 0.56 (0.32–0.99, and 0.59 (0.38–0.90, respectively; the ORs for fresh fruits consumption frequency of 1–2, 3–6, ≥7 meals/week were 0.29 (95% CI: 0.12–0.72, 0.22 (0.09–0.53, and 0.32 (0.14–0.71, respectively; the ORs for nuts consumption frequency of 1–2, 3–6, ≥7 meals/week were 0.60 (95% CI: 0.38–0.94, 0.49 (0.31–0.79, and 0.63 (0.36–1.08, respectively. Different effects of above factors on NTDs were found for subtypes of anencephaly and spina bifida. Maternal non-staple food consumption of milk, fresh fruits and nuts in the first trimester was associated with reducing NTDs risk in offspring.

Life-cycle analysis of staple food (rice, flour and corn-based fodder) production and assessments of the associated greenhouse gas (GHG) and reactive nitrogen (Nr) releases, from environmental and economic perspectives, help to develop effective mitigation options. However, such evaluations have rarely been executed in China. We evaluated the GHG and Nr releases per kilogram of staple food production (carbon and Nr footprints) and per unit of net economic benefit (CO2-NEB and Nr-NEB), and explored their mitigation potential. Carbon footprints of food production in China were obviously higher than those in some developed countries. There was a high spatial variation in the footprints, primarily attributable to differences in synthetic N use (or CH4 emissions) per unit of food production. Provincial carbon footprints had a significant linear relationship with Nr footprints, attributed to large contribution of N fertilizer use to both GHG and Nr releases. Synthetic N fertilizer applications and CH4 emissions dominated the carbon footprints, while NH3 volatilization and N leaching were the main contributors to the Nr footprints. About 564 (95% uncertainty range: 404-701) TgCO2eqGHG and 10 (7.4-12.4) Tg Nr-N were released every year during 2001-2010 from staple food production. This caused the total damage costs of 325 (70-555) billion ¥, equivalent to nearly 1.44% of the Gross Domestic Product of China. Moreover, the combined damage costs and economic input costs, accounted for 66%-80% of the gross economic benefit generated from food production. A reduction of 92.7TgCO2eqyr(-1) and 2.2TgNr-Nyr(-1) could be achieved by reducing synthetic N inputs by 20%, increasing grain yields by 5% and implementing off-season application of straw and mid-season drainage practices for rice cultivation. In order to realize these scenarios, an ecological compensation scheme should be established to incentivize farmers to gradually adopt knowledge-based managements. Copyright © 2016

Sunano, Yui

2016-07-01

For most brews, alcohol fermentation and lactic fermentation take place simultaneously during the brewing process, and alcohol fermentation can progress smoothly because the propagation of various microorganisms is prevented by lactic fermentation. It is not necessary to cause lactic fermentation with a thing generated naturally and intentionally. The people living in the Dirashe area in southern Ethiopia drink three types of alcoholic beverages that are prepared from cereals. From these alcoholic beverages, parshot is prepared by the addition of plant leaves for lactic fermentation and nech chaka by adding cereal powder for lactic fermentation before alcohol fermentation. People living in the Dirashe area partake of parshot as part of their staple diet. The brewing process used for parshot and a food culture with alcoholic beverages as parts of the staple diet are rare worldwide. This article discusses the significance of using lactic fermentation before alcoholic fermentation and focuses on lactic fermentation in the brewing methods used for the three kinds of alcoholic beverages consumed in the Dirashe area. We initially observed the brewing process and obtained information about the process from the people in that area. Next, we determined the pH and analyzed the lactic acid (g/100 g) and ethanol (g/100 g) content during lactic fermentation of parshot and nech chaka; the ethyl acetate (mg/100 g) and volatile base nitrogen (mg/100 g) content during this period was also analyzed. In addition, we compared the ethanol (g/100 g) content of all three kinds of alcoholic beverages after completion of brewing. The results showed that it was possible to consume large quantities of these alcoholic beverages because of the use of lactic fermentation before alcoholic fermentation, which improved the safety and preservation characteristics of the beverages by preventing the propagation of various microorganisms, improving flavor, and controlling the alcohol level.

Brazilian cuisine is much admired by present-day international chefs. However, in the nineteenth century, local ingredients and recipes were looked down upon by the Portuguese colonists, as well as by visiting European naturalists. This fact, together with medical and chemical views formulated throughout the 1800s, led locally trained doctors to attribute the occurrence of countless diseases that devastated Rio de Janeiro to local staple foods, particularly corn and manioc flour. In the first part of the present article, I review the dietary habits of Brazilians through the eyes of European naturalists who travelled across the country in the early nineteenth century. In the second part, I summarise the ideas formulated by French and German chemists on the components, and consequent nutritional value, of cereals and other sources of flour, and then analyse the appropriation of such ideas--particularly those of Justus Liebig--by Brazilian doctors and their adaptation to local conditions.

Double-stapling techniques for restorative rectal resection have been effective in minimizing local contamination compared with open circular stapling techniques. Inclusion of the transverse staple line closure of the distal rectal stump in the circular stapled anastomosis may minimize the risk of suture line recurrence. A technique for formation of such an anastomosis is described that avoids use of a distal purse string.

Mineral biofortification strategies for food staples: the example of common bean.

Science.gov (United States)

Blair, Matthew W

2013-09-04

Common bean is the most important directly consumed legume, especially in the least developed countries of Africa (e.g., Burundi, Democratic Republic of Congo, Rwanda, and Uganda) and Latin America (e.g., Guatemala, Nicaragua, and El Salvador). Biofortification is the process of improving staple crops for mineral or vitamin content as a way to address malnutrition in developing countries. The main goals of mineral biofortification have been to increase the concentration of iron or zinc in certain major cereals and legumes. In humans, iron is essential for preventing anemia and for the proper functioning of many metabolic processes, whereas zinc is essential for adequate growth and for resistance to gastroenteric and respiratory infections, especially in children. This paper outlines the advantages and needs of mineral biofortification in common bean, starting with the steps of breeding for the trait such as germplasm screening, inheritance, physiological, or bioavailability studies and finishing with product development in the form of new biofortified varieties.

The STAPL pList

KAUST Repository

Tanase, Gabriel

2010-01-01

We present the design and implementation of the stapl pList, a parallel container that has the properties of a sequential list, but allows for scalable concurrent access when used in a parallel program. The Standard Template Adaptive Parallel Library (stapl) is a parallel programming library that extends C++ with support for parallelism. stapl provides a collection of distributed data structures (pContainers) and parallel algorithms (pAlgorithms) and a generic methodology for extending them to provide customized functionality. stapl pContainers are thread-safe, concurrent objects, providing appropriate interfaces (e.g., views) that can be used by generic pAlgorithms. The pList provides stl equivalent methods, such as insert, erase, and splice, additional methods such as split, and efficient asynchronous (non-blocking) variants of some methods for improved parallel performance. We evaluate the performance of the stapl pList on an IBM Power 5 cluster and on a CRAY XT4 massively parallel processing system. Although lists are generally not considered good data structures for parallel processing, we show that pList methods and pAlgorithms (p-generate and p-partial-sum) operating on pLists provide good scalability on more than 103 processors and that pList compares favorably with other dynamic data structures such as the pVector. © 2010 Springer-Verlag.

Folic acid levels in some food staples in Ireland are on the decline: implications for passive folic acid intakes?

Science.gov (United States)

2016-06-01

Neural tube defects are largely preventable by the maternal periconceptual consumption of folic acid. The aim of this study was to examine the levels of synthetic folic acid in foods and the range of food stuffs with added folic acid available to consumers in Ireland at the current time. Three audits of fortified foods available in supermarkets in the Republic of Ireland were conducted. Researchers visited supermarkets and obtained folic acid levels from nutrition labels in 2004, 2008 and 2013/4. Levels were compared using MS Excel. The profile of foods fortified with folic acid in 2013/4 has changed since 2004. The percentage of foods fortified with folic acid has decreased as has the level of added folic acid in some food staples, such as fat/dairy spreads. Bread, milk and spreads no longer contain as much folic acid as previously (2004 and 2008). This may contribute to a decrease in folate intake and therefore may contribute to an increase in NTD rates. Research on current blood concentrations of folate status markers is now warranted. © The Author 2015. Published by Oxford University Press on behalf of Faculty of Public Health. All rights reserved.

Full Text Available The objective of this study was to investigate whether the intake level of a staple food influences the nutritional status of water-soluble vitamins in pregnant Japanese women. Urinary excretion of water-soluble vitamins was used as a biomarker for nutritional assessment. Twenty-four-hour urine samples were collected and vitamin intake was surveyed using a validated self-administered comprehensive diet history questionnaire. Subjects were categorized into bottom, middle, and upper tertiles according to the percentage of total energy intake from wheat and wheat alternatives or rice and rice alternatives. The present study showed that the nutritional status of water-soluble vitamins did not differ with intake level of wheat and wheat alternatives or rice and rice alternatives as a staple food in pregnant Japanese women.

[NITINOL shape memory staple for osteosynthesis of the scaphoid].

Science.gov (United States)

Winkel, Reiner; Schlageter, Michael

2009-11-01

Reconstruction of the scaphoid with use of NITINOL shape "memory" staples. Unstable fractures and nonunion of the middle third of the scaphoid, which need open reduction and internal fixation from palmar. The staples can only be used, if the arms of the staples can be inserted parallel to and at a distance of 3 mm to the fracture line. Allergy to nickel. Cases in which the arms of the staple cannot be inserted parallel to and at best 3 mm apart from the fracture line. In fractures, open reduction of the scaphoid through a palmar approach. If necessary, interposition of a bone graft and Kirschner wire transfixation. Drilling of the drill holes parallel and at a distance of 3 mm to the fracture line. Insertion of the NITINOL staple. In nonunion, excision of the fibrous nonunion, refreshening of the fracture surfaces, interposition of a bone graft and, if needed, fixation with a Kirschner wire. Drilling of the drill holes for the NITINOL staple and insertion of the staple. Within a few minutes the warming-up staple contracts and thereby compresses the scaphoid. Immobilization in a short cast with thumb support for 6 weeks. Control for bone healing by radiographs or computed tomography. Staples, which do not cause hardware problems, are not removed. Kirschner wires are removed after bone healing. From October 1995 to December 2006, the authors used NITINOL staples for 65 osteosyntheses of the scaphoid. Indications were 15 unstable fractures, 47 nonunions, and three partial necroses. 61 out of 65 scaphoids healed without further surgery, three of the 61 patients showed a delayed healing. Two of the four nonunions were related to the use of the NITINOL staples. Seven staples were removed, one for loosening. NITINOL shape memory staples have proven to be very helpful for osteosynthesis in fractures and nonunion of the scaphoid, if the prerequisites are given for their use.

Household Coverage of Fortified Staple Food Commodities in Rajasthan, India.

Directory of Open Access Journals (Sweden)

Grant J Aaron

Full Text Available A spatially representative statewide survey was conducted in Rajasthan, India to assess household coverage of atta wheat flour, edible oil, and salt. An even distribution of primary sampling units were selected based on their proximity to centroids on a hexagonal grid laid over the survey area. A sample of n = 18 households from each of m = 252 primary sampling units PSUs was taken. Demographic data on all members of these households were collected, and a broader dataset was collected about a single caregiver and a child in the first 2 years of life. Data were collected on demographic and socioeconomic status; education; housing conditions; recent infant and child mortality; water, sanitation, and hygiene practices; food security; child health; infant and young child feeding practices; maternal dietary diversity; coverage of fortified staples; and maternal and child anthropometry. Data were collected from 4,627 households and the same number of caregiver/child pairs. Atta wheat flour was widely consumed across the state (83%; however, only about 7% of the atta wheat flour was classified as fortifiable, and only about 6% was actually fortified (mostly inadequately. For oil, almost 90% of edible oil consumed by households in the survey was classified as fortifiable, but only about 24% was fortified. For salt, coverage was high, with almost 85% of households using fortified salt and 66% of households using adequately fortified salt. Iodized salt coverage was also high; however, rural and poor population groups were less likely to be reached by the intervention. Voluntary fortification of atta wheat flour and edible oil lacked sufficient industry consolidation to cover significant portions of the population. It is crucial that appropriate delivery channels are utilized to effectively deliver essential micronutrients to at-risk population groups. Government distribution systems are likely the best means to accomplish this goal.

2001-11-01

Stapled anopexy is a new approach for haemorrhoids requiring surgical treatment. This study reviews the available information concerning the present results of this procedure. Medline and hand search of the literature was conducted to identify available information on the procedure, with a special interest for the on-going or published randomized clinical trials. The advantages of the stapled approach of haemorrhoids were analyzed in the different areas of concern, including postoperative pain reduction, length of hospital stay and sick-leave, postoperative wound care and type and rate of complications. Continence status, symptom cure and patient satisfaction following stapled anopexy are also reported. Stapled anopexy is probably less painful than conventional haemorrhoidectomy. Other advantages in the short term result from this new approach. Long term efficacy of the procedure is still unknown.

To describe an unusual long-term complication of circular end-to-end anastomosis (CEEA) stapling in a dog. Clinical case report. An 11-year-old, female neutered, Labrador Retriever. The dog was referred for clinical signs of bowel obstruction. An enterectomy was performed 2 years before presentation using a CEEA stapling device. Palpation, plain radiographs, and ultrasound of the abdomen confirmed the presence of a mass in the bowel, causing obstruction, and requiring surgical approach. An exploratory celiotomy revealed a 5 cm mass in the jejunum, involving the site of the previous surgery. The mass was removed by enterectomy. Dissection of the mass revealed the presence of many staples at the previous enterectomy site, and a trichobezoar entangled in the exposed parts of the staples. An enterectomy was required to treat an intestinal obstruction caused by a trichobezoar entangled in a CEEA-stapled anastomosis. Development of trichobezoar and subsequent bowel obstruction should be considered an unusual but potential long-term complication of CEEA-stapled anastomosis.

Research of a novel biodegradable surgical staple made of high purity magnesium

2016-12-01

Full Text Available Surgical staples made of pure titanium and titanium alloys are widely used in gastrointestinal anastomosis. However the Ti staple cannot be absorbed in human body and produce artifacts on computed tomography (CT and other imaging examination, and cause the risk of incorrect diagnosis. The bioabsorbable staple made from polymers that can degrade in human body environment, is an alternative. In the present study, biodegradable high purity magnesium staples were developed for gastric anastomosis. U-shape staples with two different interior angles, namely original 90° and modified 100°, were designed. Finite element analysis (FEA showed that the residual stress concentrated on the arc part when the original staple was closed to B-shape, while it concentrated on the feet for the modified staple after closure. The in vitro tests indicated that the arc part of the original staple ruptured firstly after 7 days immersion, whereas the modified one kept intact, demonstrating residual stress greatly affected the corrosion behavior of the HP-Mg staples. The in vivo implantation showed good biocompatibility of the modified Mg staples, without inflammatory reaction 9 weeks post-operation. The Mg staples kept good closure to the Anastomosis, no leaking and bleeding were found, and the staples exhibited no fracture or severe corrosion cracks during the degradation.

2015-01-01

Response of three 150x150x450mm short reinforced concrete (RC) columns confined with different types of confining steel was investigated. Standard stirrups, strips and stapled strips, each having same cross-sectional area, were employed as confining steel around four comer column bars. Experimental work was aimed at probing into the affect of stapled strip confinement on post elastic behavior and ductility level under cyclic axial load. Ductility ratios, strength enhancement factor and core concrete strengths were compared to study the affect of confinement. Results indicate that strength enhancement in RC columns due to strip and stapled strip confinement was not remarkable as compared to stirrup confined column. It was found that as compared to stirrup confined column, stapled strip confinement enhanced the ductility of RC column by 183% and observed axial capacity of stapled strip confined columns was 41 % higher than the strip confined columns.

In order to decide an optimum countermeasure against farmland contaminations following a severe NPP accident, it is necessary to have a reliable tool for predicting the concentrations of radiocesium in crop plants. For the estimation of radionuclide concentrations in crop plants, various transfer parameters, which quantify the radionuclide transfer from one compartment to the next, are used in general. Some amount of transfer parameter data has been produced at the Korea Atomic Energy Research Institute (KAERI) over the last 30 years. The present work was conducted to collate the KAERI data on radiocesium in staple food crops and to suggest effective ways of using them for assessing the environmental impact of a nuclear accident. The transfer parameter values of radiocesium for rice, Chinese cabbage and radish varied considerably with soils and times of its deposition. The proposed representative values were mostly based on a limited amount of data so they cannot be considered to have a high representativeness. Accordingly, they are intended for provisional use and a continuous improvement should be made. It is necessary to produce a sufficient amount of additional domestic data on the indirect pathway by conducting root-uptake experiments with as many types of soil as possible

Analytic advances are enabling more precise definitions of the molecular composition of key food staples incorporated into contemporary diets and how the nutrient landscapes of these staples vary as a function of cultivar and food processing methods. This knowledge, combined with insights about the interrelationship between consumer microbiota configurations and biotransformation of food ingredients, should have a number of effects on agriculture, food production, and strategies for improving the nutritional value of foods and health status. These effects include decision-making about which cultivars of current or future food staples to incorporate into existing and future food systems, and which components of waste streams from current or future food manufacturing processes have nutritional value that is worth capturing. They can also guide which technologies should be applied, or need to be developed, to produce foods that support efficient microbial biotransformation of their ingredients into metabolic products that sustain health.

To assess the validity of food photographs in portion size estimation among adolescent girls in Mozambique. The study was carried out in preparation for the larger ZANE study, which used the 24 h dietary recall method. Life-sized photographs of three portion sizes of two staple foods and three sauces were produced. Participants ate weighed portions of one staple food and one sauce. After the meal, they were asked to estimate the amount of food with the aid of the food photographs. Zambezia Province, Mozambique. Ninety-nine girls aged 13–18 years. The mean differences between estimated and actual portion sizes relative to the actual portion size ranged from 219% to 8% for different foods. The respective mean difference for all foods combined was 25% (95% CI 212, 2 %). Especially larger portions of the staple foods were often underestimated. For the staple foods, between 62% and 64% of the participants were classified into the same thirds of the distribution of estimated and actual food consumption and for sauces, the percentages ranged from 38% to 63%. Bland–Altman plots showed wide limits of agreement. Using life-sized food photographs among adolescent Mozambican girls resulted in a rather large variation in the accuracy of individuals’ estimates. The ability to rank individuals according to their consumption was, however, satisfactory for most foods. There seems to be a need to further develop and test food photographs used in different populations in Sub-Saharan Africa to improve the accuracy of portion size estimates.

How I do it: the stapled ileal J pouch at restorative proctocolectomy.

LENUS (Irish Health Repository)

Martin, S T

2011-12-01

Ileal pouch-anal anastomosis (IPAA) following proctocolectomy is the preferred option for patients with medically refractory ulcerative colitis, indeterminate colitis, and familial adenomatous polyposis. However, it remains a procedure associated with morbidity and mortality. Pelvic sepsis, pouch fistulae, and anastomotic dehiscence predispose to pouch failure. We report our experience with an adaptation for the formation of the stapled ileal J pouch using the GIA™ 100 stapling device (Covidien, Mansfield, Massachusetts, USA). When creating the J pouch, we remove the bevelled plastic protector from the thin fork of the stapling device, allowing the staple line to be completed to the tip of the stapled efferent limb of the pouch, thereby minimizing potential blind ending in the efferent limb and injury to the transverse staple line.

Climate change continually affects our capabilities to feed the increasing population. Rising temperatures have the potential to shorten the crop growth duration and therefore reduce crop yields. In the past decades, China has successfully improved crop cultivars to stabilize, and even lengthen, the crop growth duration to make use of increasing heat resources. However, because of the complex cropping systems in the different regions of China, the possibility and the effectiveness of regulating crop growth duration to reduce the negative impacts of future climate change remain questionable. Here, we performed a projective analysis of the staple food crop productivity in double-rice, wheat-rice, wheat-maize, single-rice, and single-maize cropping systems in China using modeling approaches. The results indicated that from the present to the 2040s, the warming climate would shorten the growth duration of the current rice, wheat, and maize cultivars by 2-24, 11-13, and 9-29 days, respectively. The most significant shortening of the crop growth duration would be in Northeast China, where single-rice and single-maize cropping dominates the croplands. The shortened crop growth duration would consequently reduce crop productivity. The most significant decreases would be 27-31, 6-20, and 7-22% for the late crop in the double-rice rotation, wheat in the winter wheat-rice rotation, and single maize, respectively. However, our projection analysis also showed that the negative effects of the warming climate could be compensated for by stabilizing the growth duration of the crops via improvement in crop cultivars. In this case, the productivity of rice, wheat, and maize in the 2040s would increase by 4-16, 31-38, and 11-12%, respectively. Our modeling results implied that the possibility of securing future food production exists by adopting proper adaptation options in China.

Staple line leakage and bleeding are the most common problems associated with the use of surgical staplers for gastrointestinal resection and anastomotic procedures. These complications can be reduced by reinforcing the staple lines with buttressing materials. The current study reports the potential use of cholecyst-derived extracellular matrix (CEM) in non-crosslinked (NCEM) and crosslinked (XCEM) forms, and compares their mechanical performance with clinically available buttress materials [small intestinal submucosa (SIS) and bovine pericardium (BP)] in an ex vivo small intestine model.

GENETICALLY MODIFIED FOOD CROPS AND PUBLIC HEALTH

Directory of Open Access Journals (Sweden)

Alejandro Chaparro Giraldo

2008-09-01

Full Text Available The progress made in plant biotechnology has provided an opportunity to new food crops being developed having desirable traits for improving crop yield, reducing the use of agrochemicals and adding nutritional properties to staple crops. However, genetically modified (GM crops have become a subject of intense debate in which opponents argue that GM crops represent a threat to individual freedom, the environment, public health and traditional economies. Despite the advances in food crop agriculture, the current world situation is still characterised by massive hunger and chronic malnutrition, representing a major public health problem. Biofortified GM crops have been considered an important and complementary strategy for delivering naturally-fortified staple foods to malnourished populations. Expert advice and public concern have led to designing strategies for assessing the potential risks involved in cultivating and consuming GM crops. The present critical review was aimed at expressing some conflicting points of view about the potential risks of GM crops for public health. It was concluded that GM food crops are no more risky than those genetically modified by conventional methods and that these GM crops might contribute towards reducing the amount of malnourished people around the world. However, all this needs to be complemented by effective political action aimed at increasing the income of people living below the poverty-line.

2009-01-01

Stapled hemorrhoidopexy for prolapsing hemorrhoids is conceptually different from excision hemorrhoidectomy. It does not accompany the pain that usually occurs after resection of the sensitive anoderm. This study was carried out to evaluate the clinical outcome of stapled hemorrhoidopexy at The Aga Khan University Hospital. A sample of 140 patients with symptomatic second-, third-, and fourth-degree hemorrhoids and circumferential mucosal prolapse underwent stapled hemorrhoidopexy from July 2002 to July 2007. They were evaluated for postoperative morbidity, analgesic requirement, and recurrence. Seventy-eight percent were males and the mean age was 45 (range 16-90) years. The mean operative time was 35 (15-78) min. The mean parenteral analgesic doses during the first 24 h were 2.1. All patients received oral analgesics alone after 24 h. No significant postoperative morbidity was observed. The mean in-patient hospital stay was 1.3 (0-5) days. Patients were followed-up for 24 (range, 2-48) months. Minor local recurrence of hemorrhoids was seen in four patients and was managed by band ligation. Stapled hemorrhoidopexy procedure was found safe, well tolerated by patients with minimal parenteral analgesic use and early discharge from the hospital. (author)

To see how different foods were selected depending on family-togetherness at breakfast and dinner, we investigated the meals of eight thousand primary and four thousand junior high school students by questionnaire. About 70% of primary school children but less than 50% of junior high school children ate breakfast with their family. The food, eaten by children who ate meals together with their family, took more time for cooking and was more traditional with rice as the staple. Food eaten by children who did not eat with their family lacked both preparation time and staple base. Family-togetherness affects the foods of primary school children more than those of junior high school students.

Future Warming Increases Global Maize Yield Variability with Implications for Food Markets

Science.gov (United States)

Tigchelaar, M.; Battisti, D. S.; Naylor, R. L.; Ray, D. K.

2017-12-01

If current trends in population growth and dietary shifts continue, the world will need to produce about 70% more food by 2050, while earth's climate is rapidly changing. Rising temperatures in particular are projected to negatively impact agricultural production, as the world's staple crops perform poorly in extreme heat. Theoretical models suggest that as temperatures rise above plants' optimal temperature for performance, not only will mean yields decline rapidly, but the variability of yields will increase, even as interannual variations in climate remain unchanged. Here we use global datasets of maize production and climate variability combined with CMIP5 temperature projections to quantify how yield variability will change in major maize producing countries under 2°C and 4°C of global warming. Maize is the world's most produced crop, and is linked to other staple crops through substitution in consumption and production. We find that in warmer climates - absent any breeding gains in heat tolerance - the Coefficient of Variation (CV) of maize yields increases almost everywhere, to values much larger than present-day. This increase in CV is due both to an increase in the standard deviation of yields, and a decrease in mean yields. In locations where crop failures become the norm under high (4°C) warming (mostly in tropical, low-yield environments), the standard deviation of yields ultimately decreases. The probability that in any given year the most productive areas in the top three maize producing countries (United States, China, Brazil) have simultaneous production losses greater than 10% is virtually zero under present-day climate conditions, but increases to 12% under 2°C warming, and 89% under 4°C warming. This has major implications for global food markets and staple crop prices, affecting especially the 2.5 billion people that comprise the world's poor, who already spend the majority of their disposable income on food and are particularly vulnerable

Wild food plants of Remote Oceania

Directory of Open Access Journals (Sweden)

Will C. McClatchey

2012-11-01

Full Text Available Agricultural societies partly depend upon wild foods. Relationships between an agricultural society and its wild foods can be explored by examining how the society responds through colonization of new lands that have not been previously inhabited. The oldest clear example of this phenomenon took place about 5000 years ago in the tropical Western Pacific at the “boundary” interface between Near and Remote Oceania. An inventory of wild and domesticated food plants used by people living along “the remote side of ” that interface has been prepared from the literature. This was then assessed for the roles of plants at the time of original colonization of Remote Oceania. The majority of species are wild foods, and most of these are used as leafy vegetables and fruits. The wild food plants mostly serve as supplements to domesticated species, although there are a few that can be used as substitutes for traditional staples.

Purpose. During radiofrequency ablation (RFA), there is a risk that the multitined expandable electrode will come into contact with one of the surgical staples used to treat local recurrence after surgical operations. Our objective was to evaluate whether a surgical staple would influence the RFA of egg white using a multitined expandable electrode. Methods. Multitined expandable electrodes, LeVeen needles (expandable diameter 3.0 cm), were sunk into an egg white bath with (a) no surgical staple, (b) a surgical staple touching one of the tines, or (c) a surgical staple touching two of the tines simultaneously. By connecting the LeVeen needle and copper plate at the bottom of the bath, RFA was then performed on the egg whites as a substitute for human tissue. Ten egg white baths were ablated under each of conditions (a), (b), and (c), for a total of 30 sets of coagulated egg white. Results. There was no significant difference in the time from the power-on to the roll-off (i.e., the completion and shutting off of the electric circuit) or in the maximum diameter of the thermal lesion between conditions (a) and (b) or (a) and (c). However, the minimum diameter of the thermal lesion was significantly smaller in (c) compared with (a) (p < 0.01). Conclusions. Surgical staples have the capacity to interfere with the electromagnetic field and decrease the minimum diameter of the thermal lesion in the event that a staple touches two of the tines of a multitined expandable electrode during RFA. Although the difference might be small enough to be neglected under many clinical circumstances, we recommend that, if possible, the tines not be expanded near metallic material

The Importance of Animal Source Foods for Nutrient Sufficiency in the Developing World: The Zambia Scenario.

Zhang, Zhiying; Goldsmith, Peter D; Winter-Nelson, Alex

2016-05-05

There have been successful interventions fortifying staple foods to mobilize micronutrients as well as agricultural efforts to raise yields of staple foods to increase food availability. Zambia serves as an interesting case study because since 1961 there has been a notable decline in the availability of animal source foods (ASFs) and pulses and a significant increase in the supply of cassava and vegetable oils. The shift in food availability was partly attributed to the agricultural success in high-yielding and drought-resistant varieties that made cassava and oil crops more affordable and readily available. In this research, we explore another policy strategy that involves ASF as a mechanism to help remedy micronutrient inadequacies in a population. A scenario modeling analysis compares the changes in the nutrient profile of the Zambian diet through adding either staple plant source foods (PSFs) or ASFs. The scenarios under study involve the addition of (1) 18 fl oz of whole cow's milk; (2) 60 g of beef, 30 g of chicken, and 5 g of beef liver; (3) milk plus meat; or (4) 83 g of maize flour, 123 g of cassava, and other staple PSF, that is, isocaloric to the "milk + meat" group. The findings alert program planners and policy makers to the value of increasing the availability, accessibility, and utilization of ASF to simultaneously address multiple nutrient deficiencies, as well as the nutrition challenges that remain when expanding the availability of plant-based staples. © The Author(s) 2016.

Accurate tumor segmentation in [18F]-fluorodeoxyglucose positron emission tomography is crucial for tumor response assessment and target volume definition in radiation therapy. Evaluation of segmentation methods from clinical data without ground truth is usually based on physicians’ manual delineations. In this context, the simultaneous truth and performance level estimation (STAPLE) algorithm could be useful to manage the multi-observers variability. In this paper, we evaluated how this algorithm could accurately estimate the ground truth in PET imaging.Complete evaluation study using different criteria was performed on simulated data. The STAPLE algorithm was applied to manual and automatic segmentation results. A specific configuration of the implementation provided by the Computational Radiology Laboratory was used.Consensus obtained by the STAPLE algorithm from manual delineations appeared to be more accurate than manual delineations themselves (80% of overlap). An improvement of the accuracy was also observed when applying the STAPLE algorithm to automatic segmentations results.The STAPLE algorithm, with the configuration used in this paper, is more appropriate than manual delineations alone or automatic segmentations results alone to estimate the ground truth in PET imaging. Therefore, it might be preferred to assess the accuracy of tumor segmentation methods in PET imaging. (paper)

Staples are made of titanium, which elicits minimal tissue reaction. The authors have encountered foreign body reaction associated with stapled human gastrointestinal anastomoses, although the literature has no reports of this. The aim of this study was to identify the refractile foreign materials causing this reaction. Histological sections were taken from 14 gastrointestinal specimens from patients with a history of a stapled anastomosis within the specimen excised. These were reviewed by light and polarization microscopy. Scanning electron microscopy and energy dispersive X-ray analysis were carried out on these sections, staples and stapler cartridges used for gastrointestinal surgery. Foreign bodies rich in fluorine were found in three patients, and those rich in carbon in 12. Other elements identified included oxygen, calcium, sodium, potassium, magnesium, aluminium and silicon. One specimen was found to contain titanium with no surrounding foreign body reaction. Stapler cartridges contained carbon, oxygen, fluorine, calcium, sodium, potassium, magnesium, aluminium, silicon and traces of titanium. Staples were composed of pure titanium with some fibrous material on the surface containing elements found in stapler cartridges. The presence of foreign body reaction was confirmed in stapled human gastrointestinal anastomoses. The source of refractile materials eliciting this reaction was the stapler cartridges.

2015-12-01

Full Text Available While the Lapidus procedure is a widely accepted technique for treatment of hallux valgus, the optimal fixation method to maintain joint stability remains controversial. The purpose of this study was to evaluate the biomechanical properties of new Shape Memory Alloy staples arranged in different configurations in a repeatable 1st Tarsometatarsal arthrodesis model. Ten sawbones models of the whole foot (n=5 per group were reconstructed using a single dorsal staple or two staples in a delta configuration. Each construct was mechanically tested in dorsal four-point bending, medial four-point bending, dorsal three-point bending and plantar cantilever bending with the staples activated at 37°C. The peak load, stiffness and plantar gapping were determined for each test. Pressure sensors were used to measure the contact force and area of the joint footprint in each group. There was a significant (p < 0.05 increase in peak load in the two staple constructs compared to the single staple constructs for all testing modalities. Stiffness also increased significantly in all tests except dorsal four-point bending. Pressure sensor readings showed a significantly higher contact force at time zero and contact area following loading in the two staple constructs (p < 0.05. Both groups completely recovered any plantar gapping following unloading and restored their initial contact footprint. The biomechanical integrity and repeatability of the models was demonstrated with no construct failures due to hardware or model breakdown. Shape memory alloy staples provide fixation with the ability to dynamically apply and maintain compression across a simulated arthrodesis following a range of loading conditions.

Food security, wheat production and policy in South Africa: Reflections on food sustainability and challenges for a market economy

Directory of Open Access Journals (Sweden)

Francois de Wet

2018-01-01

Full Text Available The traditional concept of security has broadened over the past decades. Food security in South Africa is an imperative for human and non-human survival. In the contemporary political economy, there is a real nexus between globalisation, exploitation, the state, scarcity of resources, the market, peoples’ need to feel secure, notions of state responsibility and food production. Political economy and human security in theoretical debates and face-to-face politics are intrinsically linked. The notion of a ‘secure community’ changed. Food security and the right to quality living became a social imperative. Understanding current agricultural economics requires the ability to link security and access to food for all. In this case study, wheat production in South Africa is addressed against the interface of the global and the local including South Africa’s transition to a democratic and constitutional state with a Bill of Rights. The current security approach represents a more comprehensive understanding of what security is meant to be and include, amongst others, housing security, medical security, service delivery and food security, as set out in the Millennium Development Goals and the subsequent Sustainable Development Goals. The issue of food security is addressed here with particular reference to wheat production, related current government policies and the market economy. The authors chose to limit their socio-economic focus to a specific sector of the agricultural market, namely wheat, rather than discuss food security in South Africa in general. Wheat was chosen as a unit of analysis because as a crop, wheat used in bread is one of the staples for the majority of South Africans and given the current negative economic developments, wheat as a staple is likely to remain integral, if not increasing its status of dependability

To determine the frequency of dehiscence of hand-sutured and stapled intestinal anastomoses in the dog and compare the surgery duration for the methods of anastomosis. Historical cohort study. Two hundred fourteen client-owned dogs undergoing hand-sutured (n = 142) or stapled (n = 72) intestinal anastomoses. Medical records from 5 referral institutions were searched for dogs undergoing intestinal resection and anastomosis between March 2006 and February 2014. Demographic data, presence of septic peritonitis before surgery, surgical technique (hand-sutured or stapled), surgery duration, surgeon (resident versus faculty member), indication for surgical intervention, anatomic location of resection and anastomosis, and if dehiscence was noted postoperatively were retrieved. Estimated frequencies were summarized and presented as proportions and 95% confidence intervals (CI) and continuous outcomes as mean (95% CI). Comparisons were made across methods of anastomosis. Overall, 29/205 dogs (0.14, 95% CI 0.10-00.19) had dehiscence, including 21/134 dogs (0.16, 0.11-0.23) undergoing hand-sutured anastomosis and 8/71 dogs (0.11, 0.06-0.21) undergoing stapled anastomosis. There was no significant difference in the frequency of dehiscence across anastomosis methods (χ(2), P = .389). The mean (95% CI) surgery duration of 140 minutes (132-147) for hand- sutured anastomoses and 108 minutes (99-119) for stapled anastomoses was significantly different (t-test, P < .001). No significant difference in frequency of dehiscence was noted between hand- sutured and stapled anastomoses in dogs but surgery duration is significantly reduced by the use of staples for intestinal closure. © Copyright 2015 by The American College of Veterinary Surgeons.

Barski, Krzysztof; Binda, Artur; Kudlicka, Emilia; Jaworski, Paweł; Tarnowski, Wiesław

2018-03-01

Despite the growing experience of bariatric surgeons in performing laparoscopic sleeve gastrectomy, the number of complications involving staple line leaks remains constant. Hence a solution to avoid such complications is still sought. A defect of the staple line may be the consequence of an inappropriate choice of staple size in relation to gastric wall thickness. Due to the variable nature of gastric wall thickness, the choice of proper staple height is not obvious. In the few studies in which gastric wall thickness was measured, it was observed to decrease gradually from the antrum to the fundus. However, the authors are divided on the issue of whether gender and body mass index influence gastric wall thickness. The question whether there are other perioperative factors that would allow gastric wall thickness to be predicted remains unanswered.

Breakfast staple types affect brain gray matter volume and cognitive function in healthy children.

Directory of Open Access Journals (Sweden)

Full Text Available Childhood diet is important for brain development. Furthermore, the quality of breakfast is thought to affect the cognitive functioning of well-nourished children. To analyze the relationship among breakfast staple type, gray matter volume, and intelligence quotient (IQ in 290 healthy children, we used magnetic resonance images and applied voxel-based morphometry. We divided subjects into rice, bread, and both groups according to their breakfast staple. We showed that the rice group had a significantly larger gray matter ratio (gray matter volume percentage divided by intracranial volume and significantly larger regional gray matter volumes of several regions, including the left superior temporal gyrus. The bread group had significantly larger regional gray and white matter volumes of several regions, including the right frontoparietal region. The perceptual organization index (POI; IQ subcomponent of the rice group was significantly higher than that of the bread group. All analyses were adjusted for age, gender, intracranial volume, socioeconomic status, average weekly frequency of having breakfast, and number of side dishes eaten for breakfast. Although several factors may have affected the results, one possible mechanism underlying the difference between the bread and the rice groups may be the difference in the glycemic index (GI of these two substances; foods with a low GI are associated with less blood-glucose fluctuation than are those with a high GI. Our study suggests that breakfast staple type affects brain gray and white matter volumes and cognitive function in healthy children; therefore, a diet of optimal nutrition is important for brain maturation during childhood and adolescence.

The peak load (newton), stiffness (newton per millimeter), and plantar gapping (millimeter) were determined for each test. Pressure sensors were used to measure the contact force and area of the joint footprint in each group. There was a statistically significant increase in peak load in the two staple constructs compared to the single staple constructs for all testing modalities with P values range from 0.016 to 0.000. Stiffness also increased significantly in all tests except dorsal four-point bending. Pressure sensor readings showed a significantly higher contact force at time zero (P = 0.037) and contact area following loading in the two staple constructs (P = 0.045). Both groups completely recovered any plantar gapping following unloading and restored their initial contact footprint. The biomechanical integrity and repeatability of the models was demonstrated with no construct failures due to hardware or model breakdown. SMA staples provide fixation with the ability to dynamically apply and maintain compression across a simulated arthrodesis following a range of loading conditions.

A method to facilitate the characterization of stapled or cyclic peptides is reported via an arginine-selective derivatization strategy coupled with MS/MS analysis. Arginine residues are converted to ornithine residues through a deguanidination reaction that installs a highly selectively cleavable site in peptides. Upon activation by CID or UVPD, the ornithine residue cyclizes to promote cleavage of the adjacent amide bond. This Arg-specific process offers a unique strategy for site-selective ring opening of stapled and cyclic peptides. Upon activation of each derivatized peptide, site-specific backbone cleavage at the ornithine residue results in two complementary products: the lactam ring-containing portion of the peptide and the amine-containing portion. The deguanidination process not only provides a specific marker site that initiates fragmentation of the peptide but also offers a means to unlock the staple and differentiate isobaric stapled peptides.

The aim of this work was to form NiTi and TiNiCo body temperature activated and superelastic staples for clinical joining of mandible and face bone fractures. The alloys were obtained by VIM technique. Hot and cold processing was applied to obtain wires of required diameters. The martensitic transformation was studied by DSC, XRD, and TEM. The shape memory effects were measured by a bend and free recovery ASTM F2082-06 test. The superelasticity was recorded in the tension stress-strain and by the three-point bending cycles in an instrument equipped with a Hottinger force transducer and LVDT. Excellent superelastic behavior of TiNiCo wires was obtained after cold working and annealing at 400-500 °C. The body temperature activated shape memory staples were applied for fixation of mandibular condyle fractures. In experiments on the skull models, fixation of the facial fractures by using shape memory and superelastic staples were compared. The superelastic staples were used in osteosynthesis of zygomatico-maxillo-orbital fractures.

The present research aimed to analyse the nutrient density (ND), nutrient adequacy score (NAS) and energy density (ED) of Indonesian foods and to formulate a balanced diet using linear programming. Data on typical Indonesian diets were obtained from the Indonesian Socio-Economic Survey 2008. ND was investigated for 122 Indonesian foods. NAS was calculated for single nutrients such as Fe, Zn and vitamin A. Correlation analysis was performed between ND and ED, as well as between monthly expenditure class and food consumption pattern in Indonesia. Linear programming calculations were performed using the software POM-QM for Windows version 3. Republic of Indonesia, 2008. Public households (n 68 800). Vegetables had the highest ND of the food groups, followed by animal-based foods, fruits and staple foods. Based on NAS, the top ten food items for each food group were identified. Most of the staple foods had high ED and contributed towards daily energy fulfillment, followed by animal-based foods, vegetables and fruits. Commodities with high ND tended to have low ED. Linear programming could be used to formulate a balanced diet. In contrast to staple foods, purchases of fruit, vegetables and animal-based foods increased with the rise of monthly expenditure. People should select food items based on ND and NAS to alleviate micronutrient deficiencies in Indonesia. Dietary formulation calculated using linear programming to achieve RDA levels for micronutrients could be recommended for different age groups of the Indonesian population.

Varieties of intraoperative methods such as oversewing of staple lines or other reinforcement products are used for preventing the laparoscopic vertical sleeve gastrectomy (LSG) complications. The aim of this study is to evaluate the complication rates of the gastric stapling alone versus stapling with oversewing invagination of the staple line in the LSG. This is a single-center randomized study, Patients were randomized to two groups, 200 patients underwent LSG without reinforcement of the staple line and 200 patients underwent LSG with oversewing of the staple line. All patients were followed up for 1 year. The data collected prospectively for statistical analysis included demographics, BMI, preoperative comorbidities, operative time, complications, and hospital stay. The overall mean operative age was 33.7 ± 9.4 years and mean BMI was 42.4 ± 4.3 kg/m 2 . Patient baseline characteristics (age, gender, weight, and BMI) and comorbidities were generally a nonsignificant different between the treatment arms. Surgical time was shorter in patients of the nonreinforced group (44.3 ± vs 51.3 ± 4.3 min; p < 0.01) with lower %EWL (73 ± 13.8 vs 80.7 ± 13.6%, p < 0.01). One patient in the nonreinforced group was complicated by gastric leak. The staple-line bleeding rate was significantly lower in patients underwent oversewing of the staple line during LSG (p < 0.05). Oversewing of the staple line during LSG is a nonexpansive and easy method to decrease the incidence and severity of the postoperative bleeding. However, it is time-consuming and should be performed by experienced surgeons to avoid the complications which may occur secondary to the seroserotomy suturing.

In the spring of 1984, British Airways was involved in a major food poisoning outbreak which affected nearly 1000 passengers, aircrew and ground personnel. The operational impact was worldwide and could have resulted in the cessation of the airline's day-to-day operations. The investigation paralleled a major aircraft disaster in the number of national and international agencies involved and in the variety of disciplines engaged. Although the causative organism was rapidly identified (salmonella), and its introduction into the food chain proved to be a key factor, the scale of the outbreak was the result of an interaction of other factors. As with a major aircraft accident, none of the factors alone would have caused the near disaster that occurred.

The world food crisis in 2008 highlighted the susceptibility of the global food system to price shocks. Here we use annual staple food production and trade data from 1992-2009 to analyse the changing properties of the global food system. Over the 18 year study period, we show that the global food system is relatively homogeneous (85% of countries have low or marginal food self-sufficiency) and increases in complexity, with the number of global wheat and rice trade connections doubling and trade flows increasing by 42 and 90%, respectively. The increased connectivity and flows within these global trade networks suggest that the global food system is vulnerable to systemic disruptions, especially considering the tendency for exporting countries to switch to non-exporting states during times of food scarcity in the global markets. To test this hypothesis, we superimpose continental-scale disruptions on the wheat and rice trade networks. We find greater absolute reductions in global wheat and rice exports along with larger losses in network connectivity as the networks evolve due to disruptions in European wheat and Asian rice production. Importantly, our findings indicate that least developed countries suffer greater import losses in more connected networks through their increased dependence on imports for staple foods (due to these large-scale disturbances): mean (median) wheat losses as percentages of staple food supply are 8.9% (3.8%) for 1992-1996, increasing to 11% (5.7%) for 2005-2009. Over the same intervals, rice losses increase from 8.2% (2.2%) to 14% (5.2%). Our work indicates that policy efforts should focus on balancing the efficiency of international trade (and its associated specialization) with increased resilience of domestic production and global demand diversity.

We sought to compare postoperative pain according to the skin closure method (subcuticular sutures vs staples) after an elective term cesarean section. A randomized controlled trial of 101 women was performed. Women were randomly assigned to subcuticular sutures or staples. Operative technique and postoperative analgesia were standardized. Stratification was used for primary vs repeat cesareans. Analog pain and satisfaction scales ranging from 0-10 were completed at postoperative days 1 and 3, and at 6 weeks postoperatively. A digital photograph of the incision was taken at 6 weeks postoperatively and evaluated by 3 independent blinded observers. Pain at 6 weeks postoperatively was significantly less in the staple group (0.17 vs 0.51; P = .04). Operative time was shorter in that group (24.6 vs 32.9 minutes; P women's satisfaction. Staples are the method of choice for skin closure for elective term cesareans in our population.

Sands, David C; Morris, Cindy E; Dratz, Edward A; Pilgeram, Alice

High-yielding cereals and other staples have produced adequate calories to ward off starvation for much of the world over several decades. However, deficiencies in certain amino acids, minerals, vitamins and fatty acids in staple crops, and animal diets derived from them, have aggravated the problem of malnutrition and the increasing incidence of certain chronic diseases in nominally well-nourished people (the so-called diseases of civilization). Enhanced global nutrition has great potential to reduce acute and chronic disease, the need for health care, the cost of health care, and to increase educational attainment, economic productivity and the quality of life. However, nutrition is currently not an important driver of most plant breeding efforts, and there are only a few well-known efforts to breed crops that are adapted to the needs of optimal human nutrition. Technological tools are available to greatly enhance the nutritional value of our staple crops. However, enhanced nutrition in major crops might only be achieved if nutritional traits are introduced in tandem with important agronomic yield drivers, such as resistance to emerging pests or diseases, to drought and salinity, to herbicides, parasitic plants, frost or heat. In this way we might circumvent a natural tendency for high yield and low production cost to effectively select against the best human nutrition. Here we discuss the need and means for agriculture, food processing, food transport, sociology, nutrition and medicine to be integrated into new approaches to food production with optimal human nutrition as a principle goal.

To investigate the effcacy of the staple fixation for the treatment of hamate metacarpal joint injury. From May 2009 to November 2012,16 patients with hamate metacarpal joint injury were treated with staple fixation including 10 males and 6 females with an average age of 33.6 years old ranging from 21 to 57 years. Among them, 11 cases were on the fourth or fifth metacarpal base dislocation without fractures, 5 cases were the fourth or fifth metacarpal base dislocation with avulsion fractures of the back of hamatum. Regular X-ray review was used to observe the fracture healing, joint replacement and position of staple fixation. The function of carpometacarpal joint and metacarpophalangeal joint were evaluated according to ASIA (TAM) system evaluation method. All incision were healed well with no infection. All patients were followed up from 16 to 24 months with an average of (10.0 +/- 2.7) months. No dislocation recurred, the position of internal fixator was good,no broken nail and screw withdrawal were occurred. Five patients with avulsion fracture of the back of hamatum achieved bone healing. The function of carpometacarpal joint and metacarpophalangeal was excellent in 10 cases,good in 5 cases, moderate in 1 case. The application of the staple for the treatment of hamatometacarpal joint injury has the advantages of simple operation, small trauma, reliable fixation, early postoperative function exercise and other advantages, which is the ideal operation mode for hamatometacarpal joint injury.

Association between the frequency of meals combining "Shushoku, Shusai, and Hukusai" (Staple food, main dish, and side dish) and intake of nutrients and food groups among Japanese young adults aged 18-24 years: a cross-sectional study.

"Shushoku," "Shusai," and "Hukusai" are staple food, main dish, and side dish, respectively. The recommended meal in Japan is a combination of "Shushoku," "Shusai," and "Hukusai"; however, it remains unclear whether there is an association between the frequency of these meals and intake of nutrients and food groups. This cross-sectional study examined the association between the frequency of meals combining "Shushoku, Shusai, and Hukusai" and intake of nutrients and food groups among 664 Japanese young adults aged 18-24 y. The dietary habits of the subjects during the preceding month were assessed using a validated brief-type self-administered diet history questionnaire. The frequency of meals combining "Shushoku, Shusai, and Hukusai" was self-reported according to four categories: "less than 1 d or 1 d/wk," "2 or 3 d/wk," "4 or 5 d/wk," and "every day." In both women and men, there was an association between the higher frequency of these meals and higher intake of the following food groups: pulses, green and yellow vegetables, other vegetables, mushrooms, seaweeds, fish and shellfish, and eggs. Moreover, there was an association with higher intake of protein, polyunsaturated fat, n-6 and n-3 polyunsaturated fat, total dietary fiber, soluble and insoluble dietary fiber, β-carotene, α-tocopherol, vitamin K, thiamin, riboflavin, folate, pantothenic acid, vitamin C, potassium, calcium, magnesium, iron, and copper, and lower intake of carbohydrate in both women and men. Our findings support the hypothesis that the meals combining "Shushoku, Shusai, and Hukusai" may be associated with intake of many food groups and nutrients among Japanese young adults.

Carotenoids in staple cereals: Metabolism, regulation, and genetic manipulation

Directory of Open Access Journals (Sweden)

shengnan zhai

2016-08-01

Full Text Available Carotenoids play a critical role in animal and human health. Animals and humans are unable to synthesize carotenoids de novo, and therefore rely upon diet as sources of these compounds. However, major staple cereals often contain only small amounts of carotenoids in their grain. Consequently, there is considerable interest in genetic manipulation of carotenoid content in cereal grain. In this review, we focus on carotenoid metabolism and regulation in non-green plant tissues, as well as genetic manipulation in staple cereals such as rice, maize, and wheat. Significant progress has been made in three aspects: (1 seven carotenogenes play vital roles in carotenoid regulation in non-green plant tissues, including DXS (1-deoxyxylulose-5-phosphate synthase influencing isoprenoid precursor supply, PSY (phytoene synthase, LCYB (β-cyclase and LCYE (ε-cyclase controlling biosynthesis, HYDB (1-hydroxy-2-methyl-2-(E-butenyl 4-diphosphate reductase and CCDs (carotenoid cleavage dioxygenases responsible for degradation, and OR (orange conditioning sequestration sink; (2 pro-vitamin A-biofortified crops, such as rice and maize, were developed by either metabolic engineering or marker-assisted breeding; (3 QTLs for carotenoid content on chromosomes 3B, 7A, and 7B were consistently identified, eight carotenogenes including 23 loci were detected, and ten gene-specific markers for carotenoid accumulation were developed and applied in wheat improvement. A comprehensive and deeper understanding of the regulatory mechanisms of carotenoid metabolism in crops will be benefitical in improving our precision in improving carotenoid contents. Genomic selection and gene editing are emerging as transformative technologies for vitamin A biofortification.

When performing low anterior resection for rectal cancer with the double staple technique, -closing the rectum with a linear stapler in the abdomen can be challenging, especially when dealing with a narrow pelvis. For such instances we proposed to modify this technique by pulling the rectal stump through the anus, doing an extra-anal resection of the tumor and linear suture of the rectal stump, before performing a standard, stapled colorectal anastomosis. The purpose of this study was to assess the adequacy of this modification of the double staple technique. Retrospective review of 108 patients undergoing a stapled, low colorectal or coloanal anastomosis, after -eversion, extra-anal resection of the tumor and linear closure of the rectal stump for colorectal cancer, from January 1990 to December 2012. Operative mortality was 0.9%. Fourteen patients (13%) presented early, surgery-related complications -consisting of 7 anastomotic leaks, 5 wound infections, 1 ureteral lesion, and 1 peristomal abscess. Late complications related to surgery included 5 incisional hernias (4.6%), 4 anastomotic strictures (3.7%), 4 neurogenic bladders (3.7%) and 2 fecal incontinences (1.8%). The incidence of local disease recurrence was 10%. Surgical and oncological results validate the proposed modification of the double staple technique, when facing difficulties in suturing the rectum from the abdomen.

To compare the cost of a basket of staple foods, together with the availability and quality of fresh fruit and vegetables, by supermarket store type in high and low socioeconomic suburbs of Sydney. A food basket survey was undertaken in 100 supermarkets in the 20 highest and 20 lowest socioeconomic suburbs of Sydney. We assessed the cost of 46 foods, the range of 30 fresh fruit and vegetables and the quality of ten fresh fruit and vegetables. Two major supermarket retailers, a discount supermarket chain and independent grocery stores were surveyed. The food basket was significantly cheaper in low compared to high socioeconomic suburbs ($177 vs $189, ptype and socioeconomic status of suburb.

Most Americans consume more sodium than is recommended, the vast majority of which comes from commercially packaged and restaurant foods. In 2010 the Institute of Medicine recommended that manufacturers reduce the amount of sodium in their products. The aim was to assess the sodium content in commercially packaged food products sold in US grocery stores in 2009. With the use of sales and nutrition data from commercial sources, we created a database with nearly 8000 packaged food products sold in major US grocery stores in 2009. We estimated the sales-weighted mean and distribution of sodium content (mg/serving, mg/100 g, and mg/kcal) of foods within food groups that contribute the most dietary sodium to the US diet. We estimated the proportion of products within each category that exceed 1) the Food and Drug Administration's (FDA's) limits for sodium in foods that use a "healthy" label claim and 2) 1150 mg/serving or 50% of the maximum daily intake recommended in the 2010 Dietary Guidelines for Americans. Products in the meat mixed dishes category had the highest mean and median sodium contents per serving (966 and 970 mg, respectively). Products in the salad dressing and vegetable oils category had the highest mean and median concentrations per 100 g (1072 and 1067 mg, respectively). Sodium density was highest in the soup category (18.4 mg/kcal). More than half of the products sold in 11 of the 20 food categories analyzed exceeded the FDA limits for products with a "healthy" label claim. In 4 categories, >10% of the products sold exceeded 1150 mg/serving. The sodium content in packaged foods sold in major US grocery stores varied widely, and a large proportion of top-selling products exceeded limits, indicating the potential for reduction. Ongoing monitoring is necessary to evaluate the progress in sodium reduction. © 2015 American Society for Nutrition.

To develop a technique for approximation of end-to-end intestinal anastomoses by using a disposable skin stapler and to compare the stapling technique with an interrupted hand-sewn approximating end-to-end anastomosis of the canine jejunum. In vitro evaluation of the stapling technique, followed by an in vivo study of healing and clinical response in dogs. 18 mixed-breed adult dogs. The anastomotic technique was developed and tested in fresh canine jejunum. Fourteen stapled approximating anastomoses (SAA) and 14 hand-sewn approximating anastomoses (HAA) were performed in 6 cadavers under simulated surgical conditions. Anastomotic construction times, initial bursting strengths, initial lumen diameters, and gross appearance of the 2 techniques were compared. Healing and clinical response were evaluated in 12 purpose-bred dogs assigned to 2 groups of 6 animals each. Each dog had 1 SAA and 1 HAA performed in the jejunum, 50 cm apart. Six dogs were killed on postoperative day 4, and 6 dogs were killed on postoperative day 21. Anastomotic construction time, gross and histological healing, bursting strength, lumen diameter, and circumference were compared between techniques. Mean construction time for SAA was significantly faster than for HAA (P = .0001). None of the anastomoses leaked, and there were no major clinical complications in any dog. Bursting strengths were not significantly different at any time for the 2 techniques. Initial bursting strength was 31% to 35% of the normal jejunum. A nonsignificant decrease in bursting strength was observed by postoperative day 4 (26% to 28% of normal), and a significant increase in bursting strength was observed by postoperative day 21 (100% to 109% of normal). Neither technique decreased the initial lumen diameter. However, both techniques resulted in a similar degree of luminal stenosis as the anastomoses healed. Anastomotic lumen diameter was significantly decreased from normal in both groups at day 4 (86% to 88% of normal

Recent hydrological modeling and Earth observations have located and quantified alarming rates of groundwater depletion worldwide. This depletion is primarily due to water withdrawals for irrigation, but its connection with the main driver of irrigation, global food consumption, has not yet been explored. Here we show that approximately eleven per cent of non-renewable groundwater use for irrigation is embedded in international food trade, of which two-thirds are exported by Pakistan, the USA and India alone. Our quantification of groundwater depletion embedded in the world's food trade is based on a combination of global, crop-specific estimates of non-renewable groundwater abstraction and international food trade data. A vast majority of the world's population lives in countries sourcing nearly all their staple crop imports from partners who deplete groundwater to produce these crops, highlighting risks for global food and water security. Some countries, such as the USA, Mexico, Iran and China, are particularly exposed to these risks because they both produce and import food irrigated from rapidly depleting aquifers. Our results could help to improve the sustainability of global food production and groundwater resource management by identifying priority regions and agricultural products at risk as well as the end consumers of these products.

2016-01-01

China has a long history of eating staple plant foods which are mainly derived from food grains, especially rice and wheat. Food grain safety has been a worrying challenge on health and nutrition grounds in China, although evidence clearly suggests that expanding agricultural production is linked to reducing undernourishment. The focus of this study is to investigate consumers' anxieties about food grain safety in China. The nature and extent of consumer anxieties about grain safety, the caus...

Investigations on the Manufacturing and Mechanical Properties of Spun Yarns Made from Staple CF for Thermoset Composites

2017-12-01

Full Text Available This article reports the results of investigations carried out to produce yarns consisting of staple carbon fiber (CF obtained from process waste for the manufacturing of composites suitable especially for thermoset applications. For this purpose, a comparative analysis is done on processability between 100% staple CF and 60 weight% staple CF mixed with 40 weight% PVA fibers in carding, drawing and spinning process. The hybrid yarns are produced by varying twist level. The PVA fibers of the hybrid yarn are then dissolved using hot water treatment. The mechanical properties of yarns consisting of 100% staple CF and hybrid yarns consisting of staple CF and PVA before and after hot water treatment are investigated. Furthermore, test specimen is also prepared by impregnating 100% staple CF yarn and the hybrid yarns (after the dissolving of PVA with epoxy resin. The results of the tensile test of the yarns in consolidated state reveals that the hybrid yarn produced with 80 T/m after hot water treatment exhibits approximately 75% of the tensile strength of virgin filament tow, and it is expected that the hybrid yarns can be applied for the manufacturing of thermoset based composites for load bearing structures.

To evaluate the outcome of stapled versus sutured colo-rectal anastomosis after low anterior resection of mid-rectal carcinoma. A prospective study of fifty patients who underwent colo-rectal anastomosis following low anterior resection (LAR) of T2 mid-rectal cancers at the Egyptian National Cancer Institute during the time period from June 2010 to June 2013 was conducted. Classification was into two groups; a stapled anastomosis group I (25 patients) and a hand-sewn anastomosis group II (25 patients). All operations are evaluated regarding intra-operative complications such as anastomotic line bleeding, visceral injuries or major blood loss. The anastomotic time and operative time are documented for each operation. All patients are evaluated post-operatively for anastomotic leakage (AL), wound infection and ileus. The distance of the tumor from the anal verge was 9.6 ± 2.0 cm in group I and 9.9 ± 2.4 cm in group II. The mean operative time was 191.5 ± 16.2 min in the stapled group and 208 ± 18.6 min in the sutured group (p=0.002). The mean anastomotic times were 9.0 ± 1.9 min and 19.7 ± 12.2 min (p=0.001). Anastomotic leakage developed in three (12.0%) patients in the stapled group and in four (16.0%) patients in the sutured group (p=1.000). Post-operative ileus was observed in 3 patients in group I and one patient in group II. Wound infection developed in three (12.0%) patients in the stapled group and four (16.0%) patients in the sutured group (p=1.000). Colo-rectal anastomosis after low anterior resection for mid rectal carcinoma can be conducted safely either by stapling or hand-sewn techniques; however the stapling technique showed shorter anastomotic and operative times with no significant advantages regarding intra- or post-operative complications or hospital stay.

Reinforcement of the staple line in laparoscopic sleeve gastrectomy (LSG) is a practice that leads to less morbidity, but equivocal results have been reported in the literature. This is a prospective randomized study comparing two groups of patients who underwent LSG. In one group LSG was performed with a running absorbable suture placement at the staple line. In the other group the running suture was not placed. General data of the patients, as well as intraoperative and postoperative data, were gathered and statistically analyzed. Overall, 146 patients were subjected to LSG. In 84 patients a running suture was placed, and in 62 patients no suture was placed. No significant differences were found between the two groups in demographic data. No significant differences were found also in the intraoperative data, such as number of trocars, number and type of cartridges, drain placement, and operative time (45±21 versus 40±20 minutes, respectively; Prunning suture (9.5% versus 0.0%, respectively; P.05). After this randomized study, final conclusions about the efficacy of this running suture to the staple line cannot be made. To the contrary, problems seem to exist after such reinforcement of the staple line, such as hematomas. Dealing with possible leaks and hemorrhage of the staple line is also problematic after placement of the running suture.

The study aim was to analyse the safety and feasibility of laparoscopic intersphincteric resection with stapled coloanal anastomosis for low rectal cancer. Between March 2009 and August 2010, 22 patients underwent laparoscopic intersphincteric resection with a stapled coloanal anastomosis without a diverting ileostomy. The results were compared retrospectively with hand-sewn coloanal anastomoses performed between January 2001 and May 2009, which included 55 open and 38 laparoscopic intersphincteric resections. The morbidity comparison only included data relevant to the anastomosis. Function was compared using the Saito function questionnaire and the Wexner score and only involved data relevant to the laparoscopy. The anastomotic complication rates were similar for fistula, bleeding and neorectal mucosal prolapse (P = 0.526, P = 0.653 and P = 0.411, respectively). Anastomotic leakage and stricture formation of the stapled coloanal anastomosis were significantly lower than those of the hand-sewn coloanal anastomosis (P = 0.037 and P = 0.028, respectively). There were no significant differences in the Saito function questionnaire and the Wexner score between the stapled and hand-sewn coloanal anastomotic groups (all P > 0.05). Laparoscopic intersphincteric resection with a stapled coloanal anastomosis is technically feasible and is less likely to result in anastomotic leakage and stricture formation than a hand-sewn anastomosis.

Polyproteins, individual protein units joined covalently in tandem, have evolved as a promising tool for measuring the dynamic folding of biomacromolecules in single-molecule force spectroscopy. However, the synthetic routes to prepare polyproteins have been a bottleneck, and urge development of in vitro methods to knit individual protein units covalently into polyprotein. Employing two enzymes of orthogonal functionalities periodically in sequence, we synthesized monodispersed polyproteins on a solid surface. We used Sortase A (SrtA), the enzyme known for sequence specific transpeptidation, to staple protein units covalently through peptide bonds. Exploiting the sequence-specific peptide cleaving ability of TEV protease, we controlled the progress of the reaction to one attachment at a time. Finally, with unique design of the unit proteins we control the orientation of proteins in polyprotein. This simple conjugation has the potential to staple proteins with different functionalities and from different expression systems, in any number in the polyprotein and, above all, via irreversible peptide bonds. Multiple chimeric constructs can also be synthesized with interchangeable protein units.

2000-04-01

The aim of this study was to investigate the possible deleterious effect of the lateral intersecting margins (so-called dog ears) on anastomotic disruption after experimentally performed double-stapled anastomoses. Two groups of double-stapled side-to-end anastomoses were performed using pig small intestines. Group A consisted of 35 circular anastomoses and Group B of 32 double-stapled anastomoses with a bilateral dog ear. In both groups bursting pressures were tested using a water-filled, pressure-controlled automatic pumping system (Hamou Endomat), and special attention was paid to the location(s) in the anastomoses were the disruption(s) occurred. In Group A bursting pressures were significantly higher than in Group B (median pressure, 90 vs. 60 mmHg; P dog ear. We conclude that the lateral intersections of double-stapled anastomoses are a structural weak spot and that the currently most often applied double-stapled anastomosis is a less effective type of anastomosis than a complete circular one. Resolving this technical problem might help to reduce the number of anastomotic disruptions after low anterior resections.

Long-term outcome of stapled transanal rectal resection (STARR) versus stapled hemorrhoidopexys (STH) for grade III-IV hemorrhoids: preliminary results.

Circular stapled transanal hemorrhoidopexy (STH) was first introduced by A. Longo for the correction of internal mucosal prolapse and obstructed defecation and in 1998, was proposed as alternative to conventional excisional hemorrhoidectomy. More recently, stapled transanal rectal resection (STARR) has gradually gained popularity, as the Longo procedure, in the treatment of hemorrhoids. The aim of our study was to evaluate the usefulness of STARR as alternative to STH in patients with grade III (n=218, 68.1%) and IV (n=102, 31.9%) hemorrhoids. A group of 320 consecutive patients (median age=51 years; range=16-85) underwent STH (n=281) or STARR (n=39) procedure. The rate of postoperative bleeding (53.8% vs. 74.4%, phemorrhoids and a lower incidence of prolapse, both at one year (none vs. 1.4%, p=0.593 and 2.6% vs. 5.3%, p=0.396, respectively) and at two years (none vs. 6.8%, p=0.078 and none vs. 13.2%, p=0.012, respectively). The one-year (9.0 ± 1.8 vs. 9.4 ± 0.7, p=0.171) and two-year (9.6 ± 0.8 vs. 9.1 ± 1.7, p=0.072) general satisfaction was similar but higher in STARR patients than in the STH group. In conclusion, according to our preliminary results, the STARR procedure leads to a lower incidence of complications and recurrences and should be considered for patients with grade III or IV hemorrhoids previously selected for stapled hemorrhoidectomy, as a promising alternative to STH.

Introduction Anastomotic leak is one of the main causes of morbidity following esophageal resection for carcinoma of the esophagus and gastroesophageal junction. We compared hand sewn and stapled cervical esophagogastric anastomotic techniques in terms of postoperative complications. Methods All patients who underwent esophagectomy with cervical esophagogastric anastomosis at a single academic center from 2004 to 2014 were included in the study. Both early and late complications were analyzed. Results 153 patients underwent resection for carcinoma of the esophagus and gastroesophageal junction. Of these 140 patients had esophagectomy with cervical esophagogastric anastomosis. 66 patients underwent a hand sewn anastomosis and 74 patients had a side-to-side stapled anastomosis fashioned. Both groups were comparable with respect to preoperative characteristics. There was no difference in the operative blood loss and T and N stage of the disease. The overall morbidity and mortality was 32.8% and 6.4%, respectively. Overall leak rate was 17%. There was no difference in the leak rates among two groups (12 in the hand-sewn group & 12 in the Stapled stapled group; p = 0.82). The rate of anastomotic stricture was significantly higher for the hand sewn group (16.1% vs 4.3%; p = 0.03) at median follow up of 30 months. Conclusion Both hand sewn and stapled anastomotic techniques are equally effective way of performing a cervical esophagogastric anastomosis. However, patients having anastomotic leak develop anastomotic stricture more often in those having hand-sewn anastomosis compared to stapled anastomosis. PMID:27222711

Evidence of whether nutrition students are free from food-related issues or at higher risk for eating disorders is inconsistent. This study aimed to assess disordered eating behaviors and food addiction among nutrition and non-nutrition major college students. Students ( n = 967, ages 18-25, female 72.7%, white 74.8%) enrolled at a public university completed online demographic characteristics surveys and validated questionnaires measuring specific disordered eating behaviors. Academic major category differences were compared. Additionally, high risk participants were assessed by weight status and academic year. Overall, 10% of respondents were a high level of concern for developing eating disorders. About 10.3% of respondents met criteria for food addiction. In addition, 4.5% of respondents had co-occurrence of eating disorder risk and food addiction risk out of total respondents. There were no significant differences in level of concern for developing an eating disorder, eating subscales, or food addiction among academic majors. The percentage of high risk participants was lower in the underweight/normal weight group than in the overweight/obese group in health-related non-nutrition major students but not in nutrition students. Early screening, increasing awareness, and promoting healthy eating habits could be potential strategies to help treat and prevent the development of disorders or associated health conditions in nutrition as well as non-nutrition students.

Full Text Available Bangladesh has experienced rapid economic growth and achieved major health improvements in the past decade, but malnutrition rates remain high. A nationally representative study conducted in 2011 assessed the dietary habits of 841 children 24–59 months old, 1428 children 6–14 years old, and 1412 nonpregnant, nonlactating women. The study’s objective was to assess dietary intakes of key micronutrients and the consumption pattern of potentially fortifiable foods, and then to model the potential impact of the fortification of key staple foods. The current intakes of several micronutrients—namely, iron, zinc, folate, vitamin A, and vitamin B12—were found to be insufficient to meet the needs of Bangladesh’s children and women. The fortification of rice with iron and zinc and edible oil with vitamin A has the potential to fill a significant part of the nutrient gap, as these are consumed widely and in significant amounts. Wheat flour and sugar are not as promising food vehicles in the Bangladeshi context, as they were consumed by a smaller portion of the population and in smaller amounts. In conclusion, fortification of rice and oil is recommended to address the large gap in micronutrient intakes.

2011-02-01

Overweight/obesity, caused by the 'nutrition transition', is identified as one of the leading risk factors for non-communicable mortality. The nutrition transition in developing countries is associated with a major shift from the consumption of staple crops and whole grains to highly and partially processed foods. This study examines the contribution of processed foods consumption to the prevalence of overweight/obesity in Guatemala using generalized methods of moments (GMM) regression. The results show that all other things remaining constant, a 10% point increase in the share of partially processed foods from the total household food expenditure increases the BMI of family members (aged 10 years and above) by 3.95%. The impact of highly processed foods is much stronger. A 10% point increase in the share of highly processed food items increases the BMI of individuals by 4.25%, ceteris paribus. The results are robust when body weight is measured by overweight/obesity indicators. These findings suggest that increasing shares of partially and highly processed foods from the total consumption expenditure could be one of the major risk factors for the high prevalence of overweight/obesity in the country.

We investigated the cause of pneumothorax recurrence after thoracoscopic surgery and the effectiveness of staple line reinforcement with fleece-coated fibrin glue (TachoComb) in the prevention of postoperative pneumothorax recurrence. From April 3, 1992 to the end of December 2005, thoracoscopic bullectomy was performed on 499 patients of primary spontaneous pneumothorax. The causes of recurrence were investigated on 39 patients on the basis of surgical observations, preoperative chest computed tomography, and so on. The most common cause was new bulla formation (37 cases), 19 of which were apparently related to the staple line (within 1 cm of the staple lines) and 15 of which were not related to the staple line. After 2000, we stopped using forceps to grasp lungs and we have reinforced the staple line by applying fleece-coated fibrin glue. The staple line reinforced with fleece-coated fibrin glue, or sprayed with fibrin glue solution and the untreated group (bullectomy only with staples) were compared, and the recurrence rates were 1.22%, 7.25%, and 10.00%, respectively (P=0.0006021). The recurrence rate after thoracoscopic bullectomy with fleece-coated fibrin glue was significantly lowered and we consider this procedure to be the treatment of choice for the management of spontaneous pneumothorax.

Behavioral dimensions of food security.

Science.gov (United States)

Timmer, C Peter

2012-07-31

The empirical regularities of behavioral economics, especially loss aversion, time inconsistency, other-regarding preferences, herd behavior, and framing of decisions, present significant challenges to traditional approaches to food security. The formation of price expectations, hoarding behavior, and welfare losses from highly unstable food prices all depends on these behavioral regularities. At least when they are driven by speculative bubbles, market prices for food staples (and especially for rice, the staple food of over 2 billion people) often lose their efficiency properties and the normative implications assigned by trade theory. Theoretical objections to government efforts to stabilize food prices, thus, have reduced saliency, although operational, financing, and implementation problems remain important, even critical. The experience of many Asian governments in stabilizing their rice prices over the past half century is drawn on in this paper to illuminate both the political mandates stemming from behavioral responses of citizens and operational problems facing efforts to stabilize food prices. Despite the theoretical problems with free markets, the institutional role of markets in economic development remains. All policy instruments must operate compatibly with prices in markets. During policy design, especially for policies designed to alter market prices, incentive structures need to be compatible with respect to both government capacity (bureaucratic and budgetary) and empirical behavior on the part of market participants who will respond to planned policy changes. A new theoretical underpinning to political economy analysis is needed that incorporates this behavioral perspective, with psychology, sociology, and anthropology all likely to make significant contributions.

Fortification of foods with vitamin D in India.

Science.gov (United States)

G, Ritu; Gupta, Ajay

2014-09-12

Vitamin D deficiency is widely prevalent in India, despite abundant sunshine. Fortification of staple foods with vitamin D is a viable strategy to target an entire population. Vitamin D fortification programs implemented in the United States and Canada have improved the vitamin D status in these countries, but a significant proportion of the population is still vitamin D deficient. Before fortification programs are designed and implemented in India, it is necessary to study the efficacy of the American and Canadian vitamin D fortification programs and then improve upon them to suit the Indian scenario. This review explores potential strategies that could be used for the fortification of foods in the Indian context. These strategies have been proposed considering the diverse dietary practices necessitated by social, economic, cultural and religious practices and the diverse climatic conditions in India. Fortification of staple foods, such as chapati flour, maida, rice flour and rice, may be more viable strategies. Targeted fortification strategies to meet the special nutritional needs of children in India are discussed separately in a review entitled, "Fortification of foods with vitamin D in India: Strategies targeted at children".

Reduction of phytic acid and enhancement of bioavailable micronutrients in food grains.

Gupta, Raj Kishor; Gangoliya, Shivraj Singh; Singh, Nand Kumar

2015-02-01

More than half of the world populations are affected by micronutrient malnutrition and one third of world's population suffers from anemia and zinc deficiency, particularly in developing countries. Iron and zinc deficiencies are the major health problems worldwide. Phytic acid is the major storage form of phosphorous in cereals, legumes, oil seeds and nuts. Phytic acid is known as a food inhibitor which chelates micronutrient and prevents it to be bioavailabe for monogastric animals, including humans, because they lack enzyme phytase in their digestive tract. Several methods have been developed to reduce the phytic acid content in food and improve the nutritional value of cereal which becomes poor due to such antinutrient. These include genetic improvement as well as several pre-treatment methods such as fermentation, soaking, germination and enzymatic treatment of grains with phytase enzyme. Biofortification of staple crops using modern biotechnological techniques can potentially help in alleviating malnutrition in developing countries.

Occurrence, Toxicity, and Analysis of Major Mycotoxins in Food

Full Text Available Mycotoxins are toxic secondary metabolites produced by certain filamentous fungi (molds. These low molecular weight compounds (usually less than 1000 Daltons are naturally occurring and practically unavoidable. They can enter our food chain either directly from plant-based food components contaminated with mycotoxins or by indirect contamination from the growth of toxigenic fungi on food. Mycotoxins can accumulate in maturing corn, cereals, soybeans, sorghum, peanuts, and other food and feed crops in the field and in grain during transportation. Consumption of mycotoxin-contaminated food or feed can cause acute or chronic toxicity in human and animals. In addition to concerns over adverse effects from direct consumption of mycotoxin-contaminated foods and feeds, there is also public health concern over the potential ingestion of animal-derived food products, such as meat, milk, or eggs, containing residues or metabolites of mycotoxins. Members of three fungal genera, Aspergillus, Fusarium, and Penicillium, are the major mycotoxin producers. While over 300 mycotoxins have been identified, six (aflatoxins, trichothecenes, zearalenone, fumonisins, ochratoxins, and patulin are regularly found in food, posing unpredictable and ongoing food safety problems worldwide. This review summarizes the toxicity of the six mycotoxins, foods commonly contaminated by one or more of them, and the current methods for detection and analysis of these mycotoxins.

Two commonly performed surgical interventions are available for severe (grade II-IV) haemorrhoids; traditional excisional surgery and stapled haemorrhoidopexy. Uncertainty exists as to which is most effective. The eTHoS trial was designed to establish the clinical effectiveness and cost-effectiveness of stapled haemorrhoidopexy compared with traditional excisional surgery. The eTHoS trial was a large, open-label, multicentre, parallel-group, pragmatic randomised controlled trial done in adult participants (aged 18 years or older) referred to hospital for surgical treatment for grade II-IV haemorrhoids. Participants were randomly assigned (1:1) to receive either traditional excisional surgery or stapled haemorrhoidopexy. Randomisation was minimised according to baseline EuroQol 5 dimensions 3 level score (EQ-5D-3L), haemorrhoid grade, sex, and centre with an automated system to stapled haemorrhoidopexy or traditional excisional surgery. The primary outcome was area under the quality of life curve (AUC) measured with the EQ-5D-3L descriptive system over 24 months, assessed according to the randomised groups. The primary outcome measure was analysed using linear regression with adjustment for the minimisation variables. This trial is registered with the ISRCTN registry, number ISRCTN80061723. Between Jan 13, 2011, and Aug 1, 2014, 777 patients were randomised (389 to receive stapled haemorrhoidopexy and 388 to receive traditional excisional surgery). Stapled haemorrhoidopexy was less painful than traditional excisional surgery in the short term and surgical complication rates were similar between groups. The EQ-5D-3L AUC score was higher in the traditional excisional surgery group than the stapled haemorrhoidopexy group over 24 months; mean difference -0·073 (95% CI -0·140 to -0·006; p=0·0342). EQ-5D-3L was higher for stapled haemorrhoidopexy in the first 6 weeks after surgery, the traditional excisional surgery group had significantly better quality of life

Food price seasonality in Africa: Measurement and extent.

Gilbert, Christopher L; Christiaensen, Luc; Kaminski, Jonathan

2017-02-01

Everyone knows about seasonality. But what exactly do we know? This study systematically measures seasonal price gaps at 193 markets for 13 food commodities in seven African countries. It shows that the commonly used dummy variable or moving average deviation methods to estimate the seasonal gap can yield substantial upward bias. This can be partially circumvented using trigonometric and sawtooth models, which are more parsimonious. Among staple crops, seasonality is highest for maize (33 percent on average) and lowest for rice (16½ percent). This is two and a half to three times larger than in the international reference markets. Seasonality varies substantially across market places but maize is the only crop in which there are important systematic country effects. Malawi, where maize is the main staple, emerges as exhibiting the most acute seasonal differences. Reaching the Sustainable Development Goal of Zero Hunger requires renewed policy attention to seasonality in food prices and consumption.

Although stapling is an alternative to hand-suturing in gastrointestinal surgery, recent trials specifically designed to evaluate differences between the two in surgery time, anastomosis time, and return to bowel activity are lacking. This trial compared the outcomes of the two in subjects undergoing open gastrointestinal surgery. Adult subjects undergoing emergency or elective surgery requiring a single gastric, small, or large bowel anastomosis were enrolled into this open-label, prospective, randomized, interventional, parallel, multicenter, controlled trial. Randomization was assigned in a 1:1 ratio between the hand-sutured group (n = 138) and the stapled group (n = 142). Anastomosis time, surgery time, and time to bowel activity were collected and compared as primary endpoints. A total of 280 subjects were enrolled from April 2009 to September 2010. Only the time of anastomosis was significantly different between the two arms: 17.6 ± 1.90 min (stapled) and 20.6 ± 1.90 min (hand-sutured). This difference was deemed not clinically or economically meaningful. Safety outcomes and other secondary endpoints were similar between the two arms. Mechanical stapling is faster than hand-suturing for the construction of gastrointestinal anastomoses. Apart from this, stapling and hand-suturing are similar with respect to the outcomes measured in this trial.

Full Text Available Agricultural products, especially cereal grains, serve as staple foods in sub-Saharan Africa. However, climatic conditions in this region can lead to contamination of these commodities by moulds, with subsequent production of mycotoxins posing health risks to both humans and animals. There is limited documentation on the occurrence of mycotoxins in sub-Saharan African countries, leading to the exposure of their populations to a wide variety of mycotoxins through consumption of contaminated foods. This review aims at highlighting the current status of mycotoxin contamination of food products in Zimbabwe and recommended strategies of reducing this problem. Zimbabwe is one of the African countries with very little information with regards to mycotoxin contamination of its food commodities, both on the market and at household levels. Even though evidence of multitoxin occurrence in some food commodities such as maize and other staple foods exist, available published research focuses only on Aspergillus and Fusarium mycotoxins, namely aflatoxins, deoxynivalenol (DON, trichothecenes, fumonisins, and zearalenone (ZEA. Occurrence of mycotoxins in the food chain has been mainly associated with poor agricultural practices. Analysis of mycotoxins has been done mainly using chromatographic and immunological methods. Zimbabwe has adopted European standards, but the legislation is quite flexible, with testing for mycotoxin contamination in food commodities being done voluntarily or upon request. Therefore, the country needs to tighten its legislation as well as adopt stricter standards that will improve the food safety and security of the masses.

Burns, Cate; Cook, Kay; Mavoa, Helen

2013-12-01

The public health literature suggests that the cheapness of energy-dense foods is driving the obesity epidemic. We examined food purchases in low-income families and its relationship to the price of food and availability of funds. In-depth interviews were conducted with 22 parents with children less than 15 years of age whose major source of income was a government pension. A photo taxonomy, where participants sorted 50 photos of commonly purchased foods, was used to explore food choice. The most common food groupings used by the participants were: basic, emergency, treat and comfort. The process of food purchase was described by participants as weighing up the attributes of a food in relation to price and money available. Shoppers nominated the basic unit of measurement as quantity per unit price and the heuristic for food choice when shopping as determining "value for money" in a process of triage relating to food purchase decisions. Participants stated satiation of hunger to be the most common "value" relative to price. Given that the foods nominated as filling tended to be carbohydrate-rich staples, we suggest that public health initiatives need to acknowledge this triage process and shape interventions to promote nutrition over satiation.

Fallback foods and dietary partitioning among Pan and Gorilla.

2009-12-01

Recent findings on the strong preference of gorillas for fruits and the large dietary overlap between sympatric gorillas and chimpanzees has led to a debate over the folivorous/frugivorous dichotomy and resource partitioning. To add insight to these arguments, we analyze the diets of sympatric gorillas and chimpanzees inhabiting the montane forest of Kahuzi-Biega National Park (DRC) using a new definition of fallback foods (Marshall and Wrangham: Int J Primatol 28 [2007] 1219-1235). We determined the preferred fruits of Kahuzi chimpanzees and gorillas from direct feeding observations and fecal analyses conducted over an 8-year period. Although there was extensive overlap in the preferred fruits of these two species, gorillas tended to consume fewer fruits with prolonged availability while chimpanzees consumed fruits with large seasonal fluctuations. Fig fruit was defined as a preferred food of chimpanzees, although it may also play a role as the staple fallback food. Animal foods, such as honey bees and ants, appear to constitute filler fallback foods of chimpanzees. Tool use allows chimpanzees to obtain such high-quality fallback foods during periods of fruit scarcity. Among filler fallback foods, terrestrial herbs may enable chimpanzees to live in small home ranges in the montane forest, whereas the availability of animal foods may permit them to expand their home range in arid areas. Staple fallback foods including barks enable gorillas to form cohesive groups with similar home range across habitats irrespective of fruit abundance. These differences in fallback strategies seem to have shaped different social features between sympatric gorillas and chimpanzees.

This prospective clinical study evaluated the use, complications, and clinical and ultrasonographic follow-ups of end-to-end intestinal anastomoses with skin staples in naturally occurring diseases in canine small and large intestines. Intestinal anastomoses were performed in 14 dogs and pre-, peri-, and postoperative data were recorded. Postoperative clinical and ultrasound evaluations were performed at regular intervals for 1 year. The mean time taken to construct the anastomosis was 5 min. There were no intraoperative complications. Hemorrhage and colonic stricture were the main postoperative complications. Staple loss occurred in 2 cases. Absence of wall layering and focal wall thickening were observed in all cases at each ultrasonographic follow-up. Hyperechoic fat was observed in all but 1 of the cases at month 1. Nine dogs were alive with normal digestive function at the end of the study. The skin stapler technique enabled rapid construction of consistent anastomoses with inexpensive stapling material.

2017-06-01

Laparoscopic sleeve gastrectomy (LSG) is one of the most efficient bariatric interventions in morbidly obese patients. The most severe risk of this procedure seems to be the staple line leak, and the management of this complication can be very arduous. To share our experience in managing the staple line leak after LSG and to help to find the best procedure that should be preferred. In the 2010-2015 period we performed 223 LSG, with about 5 demonstrating severe complications - two patients with severe bleeding requiring revision surgery, and three patients with resection surface leak. We always primarily treated the staple line leak with a laparoscopic revision. Once the fistula did not spontaneously close after this treatment. A series of other methods were then indicated for this patient and only the sixth one resulted in the desirable therapeutic success. At first, our team opted for laparoscopic revision with drainage. The next procedure involved applying Ovesco and Boston clips. As a third method we performed abscess drainage through a nasobiliary tube inserted via gastroscopy. Due to failure we performed the second laparoscopic revision with staple line resuture, the next intervention was an open revision with fistula excision and suture, and finally we opted for the application of a self-expanding metallic stent, which proved to be definitely curative. Without any guidelines it is very difficult to determine the right procedure addressing the staple line leak after LSG. It depends mainly on the clinician's experience and is lengthy and often untraditional.

Samples of maize, teff, red pepper, and coffee (green bean and coffee bean with pulp) were collected from a local market in the Jimma Zone, Ethiopia. Samples were analyzed for the occurrence of cypermethrin, permethrin, deltamethrin, chlorpyrifos ethyl, DTT and its metabolites, and endosulfan (α, β). In the analytical procedure, the QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) extraction methodology with dispersive solid phase extraction clean up (d-SPE) technique was applied. Validation of the QuEChERS method was satisfactory. Recovery percentages of most pesticides were in the range of 70% to 120%, with good repeatability (%relative standard deviation coffee bean. Residues of DDT in coffee pulp significantly differed (p < 0.01) from other food items except for red pepper. The concentration of pesticides in the food items varied from 0.011 mg/kg to 1.115 mg/kg. All food items contained 1 or more pesticides. Two-thirds of the samples had residues below corresponding maximum residue limits, and the remaining one-third of samples were above the maximum residue limits. These results indicate the need for a good pesticide monitoring program to evaluate consumer risk for the Ethiopian people. © 2014 SETAC.

2009-07-01

Surgical stapling equipment was used to create a gastropexy in 20 dogs undergoing emergency surgery for gastric dilatation and volvulus (GDV). The technique involved creation of a tunnel between the seromuscular layer and the submucosa of the pyloric antrum, and a matching tunnel beneath the right m. transversus abdominis. The arms of a gastrointestinal anastomosis stapling device were introduced into the tunnels, and the device was fired to create the gastropexy. One dog died of systemic sequelae of GDV during the early postoperative period. None of the remaining 19 dogs developed a recurrence of GDV during follow-up periods ranging from 5 to 43 months. In 11 dogs, the integrity of the gastropexy was evaluated by abdominal ultrasonography and either negative contrast gastrography or double contrast gastrography; in these dogs, the radiographic and/or the ultrasonographic findings were suggestive of an intact gastropexy. There were no complications involving the gastropexy staple line. The results of this study indicate that an effective and consistent permanent gastropexy can be created, using surgical stapling equipment.

Ecological Footprint Analysis Based on Changing Food Consumption in a Poorly Developed Area of China

Directory of Open Access Journals (Sweden)

Lin Zhen

2017-08-01

Full Text Available The per capita ecological footprint (EF is a useful tool to compare consumption with nature's ability to support this consumption. Guyuan is an economically impoverished region in China, where EF provides important insights into whether human consumption can be sustained by the local per capita biological capacity (BC, which represents the environment’s ability to support resource use. We estimated the EF of food consumption using local equivalence and yield factors, and compared EF in 1998 and 2013 with BC, which represented the existing biologically productive area (including cultivated land, grassland, forest, and water bodies that supports this consumption. Data were collected from household surveys, government statistics, and land use maps. We found that food consumption changed, with decreasing consumption of staple foods and increasing consumption of meat, eggs, milk, edible oils, fruit, and vegetables. Decreased staple food consumption decreased the EF for this food group, but the large increase in meat consumption greatly increased EF from meat production (to more than 41 times the 1998 value. Cultivated land contributed greatly to both EF and BC, and staple foods and vegetables were the main EF components for this land. Overall, EF from food consumption decreased from 1998 to 2013, but local BC remained 188,356 ha below EF (i.e., current consumption is not sustainable based on local resources. The Grain for Green program, which focuses on increasing the BC of forest and grassland by replacing degraded cultivated land with these land use types, decreased the BC of cultivated land, leading to wide spatial variation in both EF and BC. These results will inform policy development by revealing the condition of each region’s use of the locally available production resources.

2013-01-01

This paper describes the stapl Parallel Graph Library, a high-level framework that abstracts the user from data-distribution and parallelism details and allows them to concentrate on parallel graph algorithm development. It includes a customizable distributed graph container and a collection of commonly used parallel graph algorithms. The library introduces pGraph pViews that separate algorithm design from the container implementation. It supports three graph processing algorithmic paradigms, level-synchronous, asynchronous and coarse-grained, and provides common graph algorithms based on them. Experimental results demonstrate improved scalability in performance and data size over existing graph libraries on more than 16,000 cores and on internet-scale graphs containing over 16 billion vertices and 250 billion edges. © Springer-Verlag Berlin Heidelberg 2013.

2016-02-14

Epidemiological studies have suggested that flavonoids exhibit preventive effects on degenerative diseases. However, lack of sufficient data on flavonoid intake has limited evaluating the proposed effects in populations. Therefore, we aimed to estimate the total and individual flavonoid intakes among Korean adults and determine the major dietary sources of these flavonoids. We constructed a flavonoid database of common Korean foods, based on the food list reported in the 24-h recall of the Korea National Health and Nutrition Examination Survey (KNHANES) 2007-2012, using data from the Korea Functional Food Composition Table, US Department of Agriculture flavonoid database, Phenol-Explorer database and other analytical studies. This database, which covers 49 % of food items and 76 % of food intake, was linked with the 24-h recall data of 33 581 subjects aged ≥19 years in the KNHANES 2007-2012. The mean daily intake of total flavonoids in Korean adults was 318·0 mg/d, from proanthocyanidins (22·3%), flavonols (20·3%), isoflavones (18·1%), flavan-3-ols (16·2%), anthocyanidins (11·6%), flavanones (11·3%) and flavones (0·3%). The major contributing food groups to the flavonoid intake were fruits (54·4%), vegetables (20·5%), legumes and legume products (16·2%) and beverages and alcohols (3·1%), and the major contributing food items were apples (21·9%), mandarins (12·5%), tofu (11·5%), onions (9·6%) and grapes (9·0%). In the regression analysis, the consumption of legumes and legume products, vegetables and fruits predicted total flavonoid intake the most. The findings of this study could facilitate further investigation on the health benefits of flavonoids and provide the basic information for establishing recommended flavonoid intakes for Koreans.

2017-12-01

We used the powered vascular staple (PVS) instead of the conventional staple technique [the utilization of the powered linier cutter (PLC)] or ligation for total 23 segmental or subsegmental bronchi with less than 10 mm in the bronchial luminal size on computed tomography (CT) in thoracoscopic segmentectomy. Our results suggested that the availability of the PVS represents a novel advance in the armamentarium and may have a possibility of being pervasive widely however, more observative periods and further sample accumulation are needed.

The stapl Skeleton Framework

KAUST Repository

Zandifar, Mani

2015-01-01

© Springer International Publishing Switzerland 2015. This paper describes the stapl Skeleton Framework, a highlevel skeletal approach for parallel programming. This framework abstracts the underlying details of data distribution and parallelism from programmers and enables them to express parallel programs as a composition of existing elementary skeletons such as map, map-reduce, scan, zip, butterfly, allreduce, alltoall and user-defined custom skeletons. Skeletons in this framework are defined as parametric data flow graphs, and their compositions are defined in terms of data flow graph compositions. Defining the composition in this manner allows dependencies between skeletons to be defined in terms of point-to-point dependencies, avoiding unnecessary global synchronizations. To show the ease of composability and expressivity, we implemented the NAS Integer Sort (IS) and Embarrassingly Parallel (EP) benchmarks using skeletons and demonstrate comparable performance to the hand-optimized reference implementations. To demonstrate scalable performance, we show a transformation which enables applications written in terms of skeletons to run on more than 100,000 cores.

Stapled hemorrhoidopexy is associated with less postoperative pain and faster recovery. However, it may be associated with a greater risk of symptomatic recurrence. We hypothesized that undertaking a limited surgical excision of hemorrhoid disease after stapling may be a valid approach for selected patients. To compare long-term results after stapled hemorrhoidopexy with and without complementation with closed excisional technique. In a retrospective uni-institutional cohort study, sixty-five (29 men) patients underwent stapled hemorrhoidopexy and 21 (13 men) underwent stapled hemorrhoidopexy with excision. The same surgeons operated on all cases. Patients underwent stapled hemorrhoidectomy associated with excisional surgery if symptoms attributable to external hemorrhoid piles were observed preoperatively, or if residual prolapse or bulky external disease was observed after the firing of the stapler. A closed excisional diathermy hemorrhoidectomy without vascular ligation was utilized in all complemented cases. All clinical variables were obtained from a questionnaire evaluation obtained through e-mail, telephone interview, or office follow-up. The median duration of postoperative follow-up was 48.5 (6-40) months. Patients with grades 3 and 4 hemorrhoid disease were operated on more frequently using stapled hemorrhoidopexy complemented with excisional technique (95.2% vs. 55.4%, p=0.001). Regarding respectively stapled hemorrhoidopexy and stapled hemorrhoidopexy complemented with excision, there was no difference between the techniques in relation to symptom recurrence (43% and 33%, p=0.45) and median interval between surgery and symptom recurrence (30 (8-84) and 38.8 (8-65) months, p=0.80). Eight (12.3%) patients were re-operated after stapled hemorrhoidopexy and 2 (9.6%), after hemorrhoidopexy with excision (p=0.78). Patient distribution in both groups according to the degree of postoperative satisfaction was similar (p=0.97). Stapled hemorrhoidopexy combined

Full Text Available A 55-year-old female underwent low anterior resection for rectal cancer using a double stapling technique. She developed a rectovaginal fistula on the 9th postoperative day. She was discharged from hospital after undergoing transverse colostomy, and 5 months later she underwent transvaginal repair of the rectovaginal fistula. She subsequently had an uneventful recovery. The leading cause of this complication is involvement of the posterior wall of the vagina in the staple line when firing the circular stapler. Transvaginal repair with a diverting stoma for rectovaginal fistula is a safe, minimally invasive and effective method.

Energy and water tradeoffs in enhancing food security: A selective international assessment

Rice is the major staple food in most Asian countries. However, with rapidly growing populations, sustained high productivity and yields through improving water productivity is critically important. Increasingly complex energy-agriculture relationships require an in-depth understanding of water and energy tradeoffs. This study contributes to energy and food policies by analysing the complex energy, water and economics dynamics across a selection of major rice growing countries. The results show that tradeoffs exist between yield and energy inputs with high yield attributed to higher levels of energy input. The selected developed countries show higher energy productivity, relative to all other energy inputs, compared to the selected developing counties, owing to enhanced mechanisation, on-farm technology and improved farm management. Among all countries, China has the highest water productivity due to water-saving irrigation practices. These practices offer opportunities for developed and developing countries to increase water productivity at the same time taking advantage of economic and energy benefits of reduced pumping. Sustained production from agriculture is vital to food security. Improved irrigation practices can offset environmental footprints in the short run but their large-scale implementation remains an issue. In the long run, investments are needed to buffer the negative impacts of food production on the environment. Investments to boost water productivity and improved energy use efficiency in crop production are two pathways to reduce energy dependency, enhanced natural resource sustainability and ensuring future food security.

New developments in food irradiation

International Nuclear Information System (INIS)

Molins, R.

1996-01-01

Food irradiation technology is rapidly gaining worldwide acceptance as a promising tool to help alleviate some important food security and safety concerns, and to facilitate the international trade in food. Because of the different priorities that these issues receive in various countries, food irradiation is being considered by developing countries as the technology of choice over chemical fumigants in applications related to the reduction of food losses such as the insect disinfestation of stored staple and export commodities and the inhibition of sprouting of bulb and tuber crops. In contrast, the use of irradiation as a 'cold pasteurization' method to improve the hygienic quality and safety of foods is emerging as the primary field of application in developed countries. Moreover, the use of irradiation as an alternative, non-chemical quarantine treatment for fresh fruits, vegetables and other agricultural commodities entering international trade will no doubt benefit exporting as well as importing countries. 4 figs

The burden of micronutrient malnutrition is very high in India. Food fortification is one of the most cost-effective and sustainable strategies to deliver micronutrients to large population groups. Global Alliance for Improved Nutrition (GAIN) is supporting large-scale, voluntary, staple food fortification in Rajasthan and Madhya Pradesh because of the high burden of malnutrition, availability of industries capable of and willing to introduce fortified staples, consumption patterns of target foods and a conducive and enabling environment. High extraction wheat flour from roller flour mills, edible soybean oil and milk from dairy cooperatives were chosen as the vehicles for fortification. Micronutrients and levels of fortification were selected based on vehicle characteristics and consumption levels. Industry recruitment was done after a careful assessment of capability and willingness. Production units were equipped with necessary equipment for fortification. Staffs were trained in fortification and quality control. Social marketing and communication activities were carried out as per the strategy developed. A state food fortification alliance was formed in Madhya Pradesh with all relevant stakeholders. Over 260,000 MT of edible oil, 300,000 MT of wheat flour and 500,000 MT of milk are being fortified annually and marketed. Rajasthan is also distributing 840,000 MT of fortified wheat flour annually through its Public Distribution System and 1.1 million fortified Mid-day meals daily through the centralised kitchens. Concurrent monitoring in Rajasthan and Madhya has demonstrated high compliance with all quality standards in fortified foods.

Reducing Postharvest Losses during Storage of Grain Crops to Strengthen Food Security in Developing Countries.

2017-01-15

While fulfilling the food demand of an increasing population remains a major global concern, more than one-third of food is lost or wasted in postharvest operations. Reducing the postharvest losses, especially in developing countries, could be a sustainable solution to increase food availability, reduce pressure on natural resources, eliminate hunger and improve farmers' livelihoods. Cereal grains are the basis of staple food in most of the developing nations, and account for the maximum postharvest losses on a calorific basis among all agricultural commodities. As much as 50%-60% cereal grains can be lost during the storage stage due only to the lack of technical inefficiency. Use of scientific storage methods can reduce these losses to as low as 1%-2%. This paper provides a comprehensive literature review of the grain postharvest losses in developing countries, the status and causes of storage losses and discusses the technological interventions to reduce these losses. The basics of hermetic storage, various technology options, and their effectiveness on several crops in different localities are discussed in detail.

Aiming to investigate the effect of diet and food consumption with regard to health, environment, and economy in light of nutrition ecology, we studied the dimensions of nutrition and food security in urban and rural settings in the region of Chapada dos Veadeiros, Central Brazil. We tracked diet and food consumption through carbon and nitrogen stable isotope ratios in fingernails of these inhabitants together with food intake data as a proxy for their diet patterns. We estimated household food insecurity by using the Brazilian Food Insecurity Scale. Nutrition and food insecurity was observed in both urban and rural areas, but was accentuated in rural settings. The diet pattern had high δ(13)C values in fingernails and low δ(15)N. Both urban and rural areas have diets with low diversity and relying on low-quality processed food staples at the same time that nutrition and food insecurity is quite high in the region.

The Akin proximal phalangeal osteotomy is commonly used in conjunction with metatarsal osteotomies to treat hallux valgus. Multiple fixation methods including suture, wire, screw, and staple fixation have been described. The aims of this study were to assess the intraoperative and postoperative complications and to evaluate short-term postoperative outcomes in patients who underwent Akin osteotomy with staple fixation. Forty-four patients (51 feet) with painful hallux valgus were retrospectively reviewed at an average of 40.4 ± 15.8 (range, 25.9 to 79.9) weeks following an Akin osteotomy with staple fixation. Patient reported preoperative and postoperative Visual Analog Score (VAS) (0 to 10, 0 = no pain) was recorded. Level of activity was reported postoperatively. Hallux valgus angles (HVAs), intermetatarsal angles (IMAs), and hallux valgus interphalangeus angles (IPAs) were evaluated on preoperative as well as final postoperative radiographs. Postoperative clinical and radiographic examinations were used to evaluate for complications. Mean VAS improved from 4.4 ± 2.6 to 1.0 ± 1.2 (P hallux valgus correction with improvement in pain and hallux valgus deformity with a low risk for complications.

Isoform-Selective Disruption of AKAP-Localized PKA Using Hydrocarbon Stapled Peptides

Science.gov (United States)

2015-01-01

A-kinase anchoring proteins (AKAPs) play an important role in the spatial and temporal regulation of protein kinase A (PKA) by scaffolding critical intracellular signaling complexes. Here we report the design of conformationally constrained peptides that disrupt interactions between PKA and AKAPs in an isoform-selective manner. Peptides derived from the A Kinase Binding (AKB) domain of several AKAPs were chemically modified to contain an all-hydrocarbon staple and target the docking/dimerization domain of PKA-R, thereby occluding AKAP interactions. The peptides are cell-permeable against diverse human cell lines, are highly isoform-selective for PKA-RII, and can effectively inhibit interactions between AKAPs and PKA-RII in intact cells. These peptides can be applied as useful reagents in cell-based studies to selectively disrupt AKAP-localized PKA-RII activity and block AKAP signaling complexes. In summary, the novel hydrocarbon-stapled peptides developed in this study represent a new class of AKAP disruptors to study compartmentalized RII-regulated PKA signaling in cells. PMID:24422448

Do Coffee Farmers Benefit in Food Security from Participating in Coffee Cooperatives? Evidence from Southwest Ethiopia Coffee Cooperatives.

Most coffee in Ethiopia is produced by smallholder farmers who face a daily struggle to get sufficient income but also to feed their families. At the same time, many smallholder coffee producers are members of cooperatives. Yet, literature has paid little attention to the effect of cooperatives on combating food insecurity among cash crop producers including coffee farmers. The objective of the study was to investigate how coffee cooperative membership may affect food security among coffee farm households in Southwest Ethiopia. The study used cross-sectional household data on income, expenditure on food, staple food production (maize and teff), and utilization of improved inputs (fertilizer and improved seed) collected from 256 randomly selected farm households (132 cooperative members and 124 nonmembers) and applied an inverse probability weighting (IPW) estimation to assess the impact of cooperative membership on food security. The result revealed that cooperative membership has a positive and significant effect on staple food production (maize and teff) and facilitated technological transformation via increased utilization of fertilizer and improved seeds. Nonetheless, the effect on food expenditure and income could not be confirmed. Findings suggest a trade-off between coffee marketing and input supply functions of the cooperatives, impairing their true food security impact from the pooled income and production effect.

Laparoscopic sleeve gastrectomy (LSG) is currently being performed with increasing frequency worldwide. It offers an excellent weight loss and resolution of comorbidities in the short term with a very low incidence of complications. However, the ever present risk of a staple line leak is still a major concern. Since 2005, data from obese patients that undergo bariatric procedures in Germany are prospectively registered in an online database and analyzed at the Institute of Quality Assurance in Surgical Medicine. For the current analysis, all patients that had undergone primary sleeve gastrectomy for morbid obesity within a 7-year period were considered. Using the GBSR, data from 5.400 LSGs were considered for analysis. Staple line leak rate decreased during the study period from 6.5 to 1.4 %. Male gender, higher BMI, concomitant sleep apnea, conversion to laparotomy, longer operation time, use of both buttresses and oversewing, and the occurrence of intraoperative complications were associated with a significantly higher leakage rate. On multivariate analysis, operation time and year of procedure only had a significant impact on staple line leak rate. The results of the current study demonstrated that there are factors that increase the risk of a leakage which would enable surgeons to define risk groups, to more carefully select patients, and to offer a closer follow-up during the postoperative course with early recognition and adequate treatment. All future efforts should be focused on a further reduction of serious complications to make the LSG a widely accepted and safer procedure.

Modality of wound closure after total knee replacement: are staples as safe as sutures? A retrospective study of 181 patients

2011-10-01

Full Text Available Abstract Background Surgical site wound closure plays a vital role in post-operative success. This effect is magnified in regard to commonly performed elective procedures such as total knee arthroplasty. The use of either sutures or staples for skin re-approximation remains a contested subject, which may have a significant impact on both patient safety and surgical outcome. The literature remains divided on this topic. Methods Two cohorts of patients at a level one trauma and regional referral center were reviewed. Cohorts consisted of consecutive total knee arthroplasties performed by two surgeons who achieved surgical wound re-approximation by either staples or absorbable subcuticular sutures. Outcome variables included time of surgery, wound dehiscence, surgical site infection per Center for Disease Control criteria and repeat procedures for debridement and re-closure. Results 181 patients qualified for study inclusion. Staples were employed in 82 cases (45.3% of total and sutures in 99 cases (54.7%. The staples group had no complications while the sutures group had 9 (9.1%. These consisted of: 4 infections (2 superficial, one deep, one organ/space; three patients required re-suturing for dehiscence; one allergic type reaction to suture material; and one gout flare resulting in dehiscence. The mean surgical time with sutures was 122.3 minutes (sd = 33.4 and with staples was 114 minutes (sd = 24.4. Conclusion This study demonstrated significantly fewer complications with staple use than with suture use. While all complications found in this study cannot be directly attributed to skin re-approximation method, the need for further prospective, randomized trials is established.

At present, none of the conventional surgical treatments of solitary rectal ulcer associated with internal rectal prolapse seems to be satisfactory because of the high incidence of recurrence. The stapled transanal rectal resection has been demonstrated to successfully cure patients with internal rectal prolapse associated with rectocele, or prolapsed hemorrhoids. This prospective study was designed to evaluate the short-term and long-term results of stapled transanal rectal resection in patients affected by solitary rectal ulcer associated with internal rectal prolapse and nonresponders to biofeedback therapy. Fourteen patients were selected on the basis of validated constipation and continence scorings, clinical examination, anorectal manometry, defecography, and colonoscopy and were submitted to biofeedback therapy. Ten nonresponders were operated on and followed up with incidence of failure, defined as no improvement of symptoms and/or recurrence of rectal ulceration, as the primary outcome measure. Operative time, hospital stay, postoperative pain, time to return to normal activity, overall patient satisfaction index, and presence of residual rectal prolapse also were evaluated. At a mean follow-up of 27.2 (range, 24-34) months, symptoms significantly improved, with 80 percent of excellent/good results and none of the ten operated patients showed a recurrence of rectal ulcer. Operative time, hospital stay, and time to return to normal activity were similar to those reported after stapled transanal rectal resection for obstructed defecation, whereas postoperative pain was slightly higher. One patient complained of perineal abscess, requiring surgery. The stapled transanal rectal resection is safe and effective in the cure of solitary rectal ulcer associated with internal rectal prolapse, with minimal complications and no recurrences after two years. Randomized trials with sufficient number of patients are necessary to compare the efficacy of stapled transanal

Platelets are blood cells with numerous crucial pathophysiological roles in hemostasis, cardiovascular thrombotic events and cancer metastasis. Platelet activation requires the engagement of intracellular signalling pathways that involve protein-protein interactions (PPIs). A better understanding of these pathways is therefore crucial for the development of selective anti-platelet drugs. New strategies for studying PPIs in human platelets are required to overcome limitations associated with conventional platelet research methods. For example, small molecule inhibitors can lack selectivity and are often difficult to design and synthesise. Additionally, development of transgenic animal models is costly and time-consuming and conventional recombinant techniques are ineffective due to the lack of a nucleus in platelets. Herein, we describe the generation of a library of novel, functionalised stapled peptides and their first application in the investigation of platelet PPIs. Moreover, the use of platelet-permeable stapled Bim BH3 peptides confirms the part of Bim in phosphatidyl-serine (PS) exposure and reveals a role for the Bim protein in platelet activatory processes. Our work demonstrates that functionalised stapled peptides are a complementary alternative to conventional platelet research methods, and could make a significant contribution to the understanding of platelet signalling pathways and hence to the development of anti-platelet drugs.

Non-communicable diseases (NCDs) are the leading cause of mortality in Fiji, a middle-income country in the Pacific. Some food products processed sold and marketed by the food industry are major contributors to the NCD epidemic, and the food industry is widely identified as having strong economic and political power. However, little research has been undertaken on the attempts by the food industry to influence public health-related policies and programs in its favour. The "corporate political activity" (CPA) of the food industry includes six strategies (information and messaging; financial incentives; constituency building; legal strategies; policy substitution; opposition fragmentation and destabilisation). For this study, we aimed to gain a detailed understanding of the CPA strategies and practices of major food industry actors in Fiji, interpreted through a public health lens. We implemented a systematic approach to monitor the CPA of the food industry in Fiji for three months. It consisted of document analysis of relevant publicly available information. In parallel, we conducted semi-structured interviews with 10 stakeholders involved in diet- and/or public health-related issues in Fiji. Both components of the study were thematically analysed. We found evidence that the food industry adopted a diverse range of strategies in an attempt to influence public policy in Fiji, with all six CPA strategies identified. Participants identified that there is a substantial risk that the widespread CPA of the food industry could undermine efforts to address NCDs in Fiji. Despite limited public disclosure of information, such as data related to food industry donations to political parties and lobbying, we were able to identify many CPA practices used by the food industry in Fiji. Greater transparency from the food industry and the government would help strengthen efforts to increase their accountability and support NCD prevention. In other low- and middle-income countries, it

We sought to compare growth, nutritional status, and nutrient intake in children with food allergy either avoiding cow's milk or avoiding cow's milk and wheat, which are staples of the diet in young children. Infants and young children with challenge-proven allergy were recruited to this prospective study. They were strictly avoiding their allergic food triggers, either cow's milk, or cow's milk and wheat. They were counseled by a dietitian specialized in food allergies on food avoidance diets and nutritionally adequate supplementation at regular intervals. A 3-day food diary was kept. Children's height, weight, and laboratory data for nutritional parameters were monitored at 8-month intervals. A total of 18 patients avoiding milk and 28 patients avoiding milk and wheat were evaluated at an average of 12, 21, and 28 months of age. During the follow-up, the markers of nutritional status, nutrient intake or height for age, and weight for height were comparable between the two groups, although the means for anthropometric measures were below the average for age in both groups. The extent of food elimination diet has no impact on growth or nutritional status of food-allergic children, when diet is adequately supplemented. Close physician and dietitian follow-up are essential for food-allergic children when avoiding one or more foods, which are staples of the diet. © 2015 John Wiley & Sons A/S.

2016-11-01

Full Text Available It is a general socio-political objective of the mid- and long term food industry development strategy of Hungary to promote healthy food production and consumption. The realization of the strategy of the domestic food industry increasingly promotes healthy eating, for example consuming natural, domestic, fresh ingredients, prepared foods, in order to improve the overall health of the population (EFS, 2014-2020. Our study presents the regional tendencies of staple food consumption in Hungarian regions and the changes in indicators reflecting the health status of the population. Furthermore, our hypothesis states that there is a statistically provable correlation between the annual food consumption of Hungarian households per capita and the health status, on regional level.

Future technology needs for enhancing food availability and nutrition in Asia

International Nuclear Information System (INIS)

Ahloowalia, B.S.

2002-01-01

The increased food production during the past 50 years in Asia has not solved the problem of food availability and its access to large sections of the population. In addition, the nutritional level of the consumed food is highly inadequate to meet the daily requirements of minerals and vitamins. No doubt, the national policies on price support and subsidies for increasing food production and procurement have had a motor influence on access to food. However, the infrastructures for increasing storage capacity, prevent food wastage, and enhance food quality have not kept with the increased food production and its equitable access to the low income groups. The malnutrition of the poor, especially among children and women, remains a challenge to the policy makers and scientists alike. The building of food storage capacity at the village level and adoption of nuclear techniques to store grains under minimal insect and fungal infestation would cut down losses and enhance grain quality. Breeding new varieties of staple food grains (rice, wheat, maize and mallets), vegetables and fruits with enhanced minerals, vitamins and their bio-availability is seen as a complementary approach to food diversification to reduce malnutrition. Conventional breeding assisted by induced mutations, tissue culture, gene insertion and molecular gene modification holds promise to enhance food nutrition. However, the adoption of the appropriate combination of technologies is essential to enhance food availability and nutrition in Asia. Unfortunately, transgenic approach is seen by many as the only option or many times the major solution to enhance food access and its quality. It is often forgotten that a yardstick has many markings, each of which is important to reach the goal. (Author)

Jamieson, Jennifer A; Gougeon, Laura

We investigated the price difference between gluten-free (GF) and gluten-containing (GC) foods available in rural Maritime stores. GF foods and comparable GC items were sampled through random visits to 21 grocery stores in nonurban areas of Nova Scotia, New Brunswick, and Prince Edward Island, Canada. Wilcoxon rank tests were conducted on price per 100 g of product, and on the price relative to iron content; 2226 GF foods (27.2% staple items, defined as breads, cereals, flours, and pastas) and 1625 GC foods were sampled, with an average ± SD of 66 ± 2.7 GF items per store in rural areas and 331 ± 12 in towns. The median price of GF items ($1.76/100 g) was more expensive than GC counterparts ($1.05/100 g) and iron density was approximately 50% less. GF staple foods were priced 5% higher in rural stores than in town stores. Although the variety of GF products available to consumers has improved, higher cost and lower nutrient density remain issues in nonurban Maritime regions. Dietitians working in nonurban areas should consider the relative high price, difficult access, and low iron density of key GF items, and work together with clients to find alternatives and enhance their food literacy.

Describes the life history of the British Food Journal, its changing editorial team, ownership and editorial focus. The authors have used much wider source material than the archives of the journal, now in its 100th year. The journal was always closely identified with the safety of food, its adulteration and the government’s duty to safeguard the public. The second section reviews the profession and role of the public analyst, in particular the history and development of the Society of Public Analysts. The next and longest section of the monograph is devoted to an interesting examination of food safety, nutrition and food manufacturing issues over the last 100 years. Many of the points raised are illustrated by excerpts from papers written in BFJ and included as Appendices to the monograph. Food irradiation was first raised as a subject in the journal in 1928! Bread and milk as staples in the British diet are looked at in some detail in terms of their ingredients and health properties

Wild Food, Prices, Diets and Development: Sustainability and Food Security in Urban Cameroon

Directory of Open Access Journals (Sweden)

Lauren Q. Sneyd

2013-11-01

Full Text Available This article analyses wild food consumption in urban areas of Cameroon. Building upon findings from Cameroon’s Comprehensive Food Security and Vulnerability Analysis (CFSVA this case study presents empirical data collected from 371 household and market surveys in Cameroonian cities. It employs the UN Special Rapporteur on the Right to Food’s framework for understanding challenges related to the availability, accessibility, and adequacy of food. The survey data suggest that many wild/traditional foods are physically available in Cameroonian cities most of the time, including fruits, vegetables, spices, and insects. Cameroonians spend considerable sums of their food budget on wild foods. However, low wages and the high cost of city living constrain the social and economic access most people have to these foods. The data also suggest that imports of non-traditional staple foods, such as low cost rice, have increasingly priced potentially more nutritious or safe traditional local foods out of markets after the 2008 food price crisis. As a result, diets are changing in Cameroon as the resource-constrained population continues to resort to the coping strategy of eating cheaper imported foods such as refined rice or to eating less frequently. Cameroon’s nutrition transition continues to be driven by need and not necessarily by the preferences of Cameroonian consumers. The implications of this reality for sustainability are troubling.

Tables of 90 Sr and 137 Cs content in the major types of food stuffs in different regions of the USSR from 1963 to 1973, are presented. Maximum contamination is observed in 1963 and 1964. Variations of contamination of food stuffs depending upon fallout alterations during 1963-1964 are analyzed. The increased contamination of fish products, bread, deer meat and tea is observed in these years. The dependence of contamination of certain products on the area of their production is pointed out which makes possible a wide variation of results of investigations. It is established that the less contamination of food stuffs is observed in the areas with black soil. It is stated that 137 Cs contamination of food stuffs is several times higher than 90 Sr contamination, which is probably connected with a better 137 Cs uptake by vegetation from aerial fallouts

Estrogenic plant foods of red colobus monkeys and mountain gorillas in Uganda.

Phytoestrogens, or naturally occurring estrogen-mimicking compounds, are found in many human plant foods, such as soybeans (Glycine max) and other legumes. Because the consumption of phytoestrogens may result in both health benefits of protecting against estrogen-dependent cancers and reproductive costs of disrupting the developing endocrine system, considerable biomedical research has been focused on the physiological and behavioral effects of these compounds. Despite this interest, little is known about the occurrence of phytoestrogens in the diets of wild primates, nor their likely evolutionary importance. We investigated the prevalence of estrogenic plant foods in the diets of two folivorous primate species, the red colobus monkey (Procolobus rufomitratus) of Kibale National Park and mountain gorilla (Gorilla beringei) of Bwindi Impenetrable National Park, both in Uganda. To examine plant foods for estrogenic activity, we screened 44 plant items (species and part) comprising 78.4% of the diet of red colobus monkeys and 53 plant items comprising 85.2% of the diet of mountain gorillas using transient transfection assays. At least 10.6% of the red colobus diet and 8.8% of the gorilla diet had estrogenic activity. This was mainly the result of the red colobus eating three estrogenic staple foods and the gorillas eating one estrogenic staple food. All estrogenic plants exhibited estrogen receptor (ER) subtype selectivity, as their phytoestrogens activated ERβ, but not ERα. These results demonstrate that estrogenic plant foods are routinely consumed by two folivorous primate species. Phytoestrogens in the wild plant foods of these two species and many other wild primates may have important implications for understanding primate reproductive ecology.

With the increasing importance in the application of the molecular biological detection technology in the field of food safety, strengthening education in molecular biology experimental techniques is more necessary for the culture of the students in food quality and safety major. However, molecular biology experiments are not always in curricula of Food quality and safety Majors. This paper introduced a project "competition of molecular biological detection technology for food safety among undergraduate sophomore students in food quality and safety major", students participating in this project needed to learn the fundamental molecular biology experimental techniques such as the principles of molecular biology experiments and genome extraction, PCR and agarose gel electrophoresis analysis, and then design the experiments in groups to identify the meat species in pork and beef products using molecular biological methods. The students should complete the experimental report after basic experiments, write essays and make a presentation after the end of the designed experiments. This project aims to provide another way for food quality and safety majors to improve their knowledge of molecular biology, especially experimental technology, and enhances them to understand the scientific research activities as well as give them a chance to learn how to write a professional thesis. In addition, in line with the principle of an open laboratory, the project is also open to students in other majors in East China University of Science and Technology, in order to enhance students in other majors to understand the fields of molecular biology and food safety. © 2017 by The International Union of Biochemistry and Molecular Biology, 45(4):343-350, 2017. © 2017 The International Union of Biochemistry and Molecular Biology.

Laparoscopic Roux-en-Y gastric bypass (LRYGB) is a common, well-established procedure, but no consensus regarding selection of the gastrojejunostomy (GJ) technique has been reached, and standardization of this precise technique is far from being achieved. To compare circular-stapled and linear-stapled GJ in LRYGB in terms of operative time and postoperative complications. This retrospective case-control study compared the perioperative and postoperative outcomes of LRYGB with a circular-stapled (LRYGB-CS) versus linear-stapled (LRYGB-LS) gastrojejunostomy. All patients, operated on in two academic referral care centers for bariatric surgery, were enrolled from April 2013 to June 2016. 457 patients were included (255 and 202 respectively in the LRYGB-CS and LRYGB-LS groups). After matching the groups for age, sex, body mass index, arterial hypertension, and presence of type 2 diabetes in a 1 : 1 ratio, 99 patients were enrolled in each. The total operative time was longer in the LRYGB-LS group (140 vs. 85 min, p < 0.001). The postoperative hemorrhage and wound infection rates were lower in the LRYGB-LS group (2.1% vs. 10.3%, p = 0.021, and 1.0% vs. 9.3%, p = 0.011). The readmission rates were comparable (8.2% vs. 6.1%, p = 0.593). There was no significant difference in the incidence of gastrojejunostomy leakage, stricture, port-site hernia, or marginal ulcer. Both anastomosis types for LRYGB are safe and have low and comparable risks of postoperative complications. After LRYGB-CS, postoperative bleeding and wound infections are slightly more frequent; however, the operative time is shorter.

Postoperative pancreatic fistula formation remains a source of significant morbidity following distal pancreatectomy. The aim of this study was to evaluate the rate of clinically significant fistulas (International Study Group on Pancreatic Fistula grade B and grade C) after distal pancreatectomy using a fibrinogen/thrombin-based collagen fleece (TachoComb, TachoSil) with a stapled closure. Seventy-five patients underwent distal pancreatectomy at our institution between January 2005 and March 2014. A fibrinogen/thrombin-based collagen fleece was applied to the staple line of the pancreas before stapling. Twenty-six patients (34.7%) developed a pancreatic fistula, 8 patients (10.7%) developed a grade B fistula, and no patients developed a grade C fistula. The duration of the drain was significantly different in patients with or without a pancreatic fistula (8.0 ± 4.5 vs. 5.4 ± 1.3 days, P = .0003). Histological analysis showed that there was a tight covering with the fibrinogen/thrombin-based collagen fleece. The fibrinogen/thrombin-based collagen fleece (TachoComb, TachoSil) with a stapled closure has low rates of fistula formation and provides a safe alternative to the conventional stapled technique in distal pancreatectomy. © The Author(s) 2015.

An Assessment of the Impact of Fortification of Staples and Condiments on Micronutrient Intake in Young Vietnamese Children

Jacques Berger

2012-08-01

Full Text Available Targeted fortification programs for infants and young children are an effective strategy to prevent micronutrient deficiencies in developing countries, but the role of large-scale fortification of staple foods and condiments is less clear. Dietary modeling in children aged 6–60 months was undertaken, based on food consumption patterns described in the 2009 national food consumption survey, using a 24-h recall method. Consumption data showed that the median intake of a child for iron, vitamin A and zinc, as a proportion of the Vietnamese Recommended Dietary Allowance (VRDA, is respectively 16%–48%, 14%–49% and 36%–46%, (depending on the age group. Potential fortification vehicles, such as rice, fish/soy sauces and vegetable oil are consumed daily in significant amounts (median: 170 g/capita/day, 4 g/capita/day and 6 g/capita/day, respectively by over 40% of the children. Vegetable oil fortification could contribute to an additional vitamin A intake of 21%–24% of VRDA recommended nutrient intake, while fortified rice could support the intakes of all the other micronutrients (14%–61% for iron, 4%–11% for zinc and 33%–49% of folate requirements. Other food vehicles, such as wheat flour, which is consumed by 16% of children, could also contribute to efforts to increase micronutrient intakes, although little impact on the prevalence of micronutrient deficiencies can be expected if used alone. The modeling suggests that fortification of vegetable oil, rice and sauces would be an effective strategy to address micronutrient gaps and deficiencies in young children.

An enhanced functional interrogation/manipulation of intracellular signaling pathways with the peptide 'stapling' technology.

He, Y; Chen, D; Zheng, W

Specific protein-protein interactions (PPIs) constitute a key underlying mechanism for the presence of a multitude of intracellular signaling pathways, which are essential for the survival of normal and cancer cells. Specific molecular blockers for a crucial PPI would therefore be invaluable tools for an enhanced functional interrogation of the signaling pathway harboring this particular PPI. On the other hand, if a particular PPI is essential for the survival of cancer cells but is absent in or dispensable for the survival of normal cells, its specific molecular blockers could potentially be developed into effective anticancer therapeutics. Due to the flat and extended PPI interface, it would be conceivably difficult for small molecules to achieve an effective blockade, a problem which could be potentially circumvented with peptides or proteins. However, the well-documented proteolytic instability and cellular impermeability of peptides and proteins in general would make their developing into effective intracellular PPI blockers quite a challenge. With the advent of the peptide 'stapling' technology which was demonstrated to be able to stabilize the α-helical conformation of a peptide via bridging two neighboring amino-acid side chains with a 'molecular staple', a linear parent peptide could be transformed into a stronger PPI blocker with enhanced proteolytic stability and cellular permeability. This review will furnish an account on the peptide 'stapling' technology and its exploitation in efforts to achieve an enhanced functional interrogation or manipulation of intracellular signaling pathways especially those that are cancer relevant.

Food system consequences of a fungal disease epidemic in a major crop.

Godfray, H Charles J; Mason-D'Croz, Daniel; Robinson, Sherman

2016-12-05

Fungal diseases are major threats to the most important crops upon which humanity depends. Were there to be a major epidemic that severely reduced yields, its effects would spread throughout the globalized food system. To explore these ramifications, we use a partial equilibrium economic model of the global food system (IMPACT) to study a hypothetical severe but short-lived epidemic that reduces rice yields in the countries affected by 80%. We modelled a succession of epidemic scenarios of increasing severity, starting with the disease in a single country in southeast Asia and ending with the pathogen present in most of eastern Asia. The epidemic and subsequent crop losses led to substantially increased global rice prices. However, as long as global commodity trade was unrestricted and able to respond fast enough, the effects on individual calorie consumption were, to a large part, mitigated. Some of the worse effects were projected to be experienced by poor net-rice importing countries in sub-Saharan Africa, which were not affected directly by the disease but suffered because of higher rice prices. We critique the assumptions of our models and explore political economic pressures to restrict trade at times of crisis. We finish by arguing for the importance of 'stress-testing' the resilience of the global food system to crop disease and other shocks.This article is part of the themed issue 'Tackling emerging fungal threats to animal health, food security and ecosystem resilience'. © 2016 The Author(s).

2013-01-14

The SRS(TM) Endoscopic Stapling System (Medigus, Tel Aviv, Israel) is a new tool capable of creating a totally endoscopic fundoplication, combined with an endoscope, endoscopic ultrasound and a surgical stapler. SRS(TM) endoscopic stapling for gastro-esophageal reflux disease is a minimally invasive, outpatient procedure, which requires general anesthesia with positive-pressure ventilation. Keeping the patient on positive end-expiratory pressure (PEEP) may minimize the pressure gradient between the esophagus and the mediastinum, as well as help to prevent air from leaking around the screws and causing pneumomediastinum. In addition, in patients with hiatal hernia, higher PEEP levels may be required to increase intra-thoracic pressure and to force the stomach to slide into the abdomen for ease of endoscopy. We advise smoother emergence from anesthesia, taking precautions for retching, postoperative nausea and vomiting (PONV), while coughing and gagging during extubation and PONV may affect the success of the procedure. Total intravenous anesthesia with propofol and remifentanil seems to be a good choice for these reasons.

Diversifying crops for food and nutrition security - a case of teff.

Cheng, Acga; Mayes, Sean; Dalle, Gemedo; Demissew, Sebsebe; Massawe, Festo

2017-02-01

There are more than 50000 known edible plants in the world, yet two-thirds of global plant-derived food is provided by only three major cereals - maize (Zea mays), wheat (Triticum aestivum) and rice (Oryza sativa). The dominance of this triad, now considered truly global food commodities, has led to a decline in the number of crop species contributing to global food supplies. Our dependence on only a few crop species limits our capability to deal with challenges posed by the adverse effects of climate change and the consequences of dietary imbalance. Emerging evidence suggests that climate change will cause shifts in crop production and yield loss due to more unpredictable and hostile weather patterns. One solution to this problem is through the wider use of underutilised (also called orphan or minor) crops to diversify agricultural systems and food sources. In addition to being highly nutritious, underutilised crops are resilient in natural and agricultural conditions, making them a suitable surrogate to the major crops. One such crop is teff [Eragrostis tef (Zucc.) Trotter], a warm-season annual cereal with the tiniest grain in the world. Native to Ethiopia and often the sustenance for local small farmers, teff thrives in both moisture-stressed and waterlogged soil conditions, making it a dependable staple within and beyond its current centre of origin. Today, teff is deemed a healthy wheat alternative in the West and is sought-after by health aficionados and those with coeliac disease or gluten sensitivity. The blooming market for healthy food is breathing new life into this underutilised crop, which has received relatively limited attention from mainstream research perhaps due to its 'orphan crop' status. This review presents the past, present and future of an ancient grain with a potential beyond its size. © 2015 Cambridge Philosophical Society.

2018-05-01

In 2010, an estimated 400 to 500 children died of acute lead poisoning associated with artisanal gold mining in Zamfara, Nigeria. Processing of gold ores containing up to 10% lead within residential compounds put residents, especially children, at the highest risk. Principal routes of exposure were incidental ingestion and inhalation of contaminated soil and dusts. Several Nigerian and international health organizations collaborated to reduce lead exposures through environmental remediation and medical treatment. The contribution of contaminated food to total lead exposure was assessed during the environmental health response. Objectives of this investigation were to assess the influence of cultural/dietary habits on lead exposure pathways and estimate the contribution of contaminated food to children's blood lead levels (BLLs). A survey of village dietary practices and staple food lead content was conducted to determine dietary composition, caloric intakes, and lead intake. Potential blood lead increments were estimated using bio-kinetic modeling techniques. Most dietary lead exposure was associated with contamination of staple cereal grains and legumes during post-harvest processing and preparation in contaminated homes. Average post-harvest and processed cereal grain lead levels were 0.32mg/kg and 0.85mg/kg dry weight, respectively. Age-specific food lead intake ranged from 7 to 78μg/day. Lead ingestion and absorption were likely aggravated by the dusty environment, fasting between meals, and nutritional deficiencies. Contamination of staple cereal grains by highly bioavailable pulverized ores could account for as much as 11%-34% of children's BLLs during the epidemic, and were a continuing source after residential soil remediation until stored grain inventories were exhausted.

The term vitamin describes a small group of organic compounds that are absolutely required in the human diet. Although for the most part, dependency criteria are met in developed countries through balanced diets, this is not the case for the five billion people in developing countries who depend predominantly on a single staple crop for survival. Thus, providing a more balanced vitamin intake from high-quality food remains one of the grandest challenges for global human nutrition in the coming decade(s). Here, we describe the known importance of vitamins in human health and current knowledge on their metabolism in plants. Deficits in developing countries are a combined consequence of a paucity of specific vitamins in major food staple crops, losses during crop processing, and/or overreliance on a single species as a primary food source. We discuss the role that plant science can play in addressing this problem and review successful engineering of vitamin pathways. We conclude that while considerable advances have been made in understanding vitamin metabolic pathways in plants, more cross-disciplinary approaches must be adopted to provide adequate levels of all vitamins in the major staple crops to eradicate vitamin deficiencies from the global population.

A 68-year-old male with a tracheostoma due to hypopharyngeal cancer was admitted because his chest computed tomography (CT) showed a small nodule in the right middle lobe. Following a partial resection of the right middle lobe, histopathological diagnosis of the resected sample was that of organizing pneumonia. Eleven months later, chest CT showed a mass with pleural indentation and spiculation in the right middle lobe. 18-Fluorodeoxyglucose-positron emission tomography showed significant accumulation in the middle lobe tumor mass shadow. The abnormal chest shadow that had developed around surgical staples suggested inadequate resection and tumor recurrence. As the abnormal radiological shadow was enlarging, middle lobectomy was carried out. Histological examination revealed that the tumor was a lung abscess without malignant features. This is a unique case of lung abscess mimicking lung cancer which developed around staples used during partial resection of the lung.

Kaur, P.; Karandikar, S.S.; Roy-Choudhury, S.

2014-01-01

Aims: To assess accuracy of multidetector computed tomography (MDCT) and individual radiological signs in the diagnosis of anastomotic leaks. Materials and methods: Patients undergoing anterior resection with a stapled anastomosis over a 2 year period were identified. Electronic and clinical records of these patients were reviewed. Unenhanced and/or enhanced MDCT was performed with intravenous and/or per-rectal contrast medium and read by a radiologist blinded to the patients' clinical details to determine the sensitivity and specificity of specific findings at MDCT for identifying leaks. Results: Seventeen percent (30/170) of the anterior resections were suspected to have an anastomotic leak. Ninety-three percent (28/30) of patients underwent MDCT. Seven point six percent (11+2/170) had a confirmed leak. Two patients underwent surgery without MDCT. A leak was confirmed by MDCT in 91% (10/11) of patients. The sensitivity, specificity, and positive and negative predictive values of MDCT in diagnosing a leak was 0.91, 1, 1, and 0.95, respectively. The sensitivity of peri-anastomotic air, peri-anastomotic collection, extravasation of rectal contrast medium, and staple line integrity was 0.81, 0.63, 0.54, and 0.72, respectively. Use of rectal contrast medium (8/11 cases) increased the subjective ease of diagnosis and was the only sign in one patient. Conclusions: Presence of peri-anastomotic air is a reliable marker of anastomotic leaks at MDCT. Leakage of rectal contrast medium is highly accurate and increases confidence of diagnosis. The appearance of the staple line itself is not accurate in assessing anastomotic integrity

How great the influence of those changes to food consumption is the important information as the basic consideration for government in creating policy related to food consumption. The objective of the research, which has survey design, was to analyze staple food consumption and demand pattern in household in Indonesia. The research was conducted in Bogor, from March to June 2008 by using secondary data Susenas year 2005 with 64.709 households as the samples. The staple food analyzed were rice, corn, cassava, sweet potato, wheat flour and its derived product (instant noodle, noodle. Data was processed by SAS program version 6.12 and Double-Log Regression econometrical model. Then, it was analyzed descriptively. Result shows that rice has the biggest expenditure proportion among staple food. Almost all staple food is obtained by purchasing, except in corn, cassava, and sweet potatoes. Energy contribution from rice reaches half of total energy consumption. The consumption of rice, corn, cassava, sweet potatoes, wheat flour and its derived product, instant noodle, and wheat noodle per capita per year are 100.52 kg, 3.36 kg, 11.67 kg, 4.10 kg, 5.09 kg, 3.39 kg, and 0.22 kg. Staple food which has consumption participation level almost 100% is rice. The own price elasticity of staple foods are not elastic, except in corn, wheat flour and its derived product.

Indian traditional staple and snack food is typically a heterogeneous recipe that incorporates varieties of vegetables, lentils and other ingredients. Modelling the retorting process of multilayer pouch packed Indian food was achieved using lumped-parameter approach. A unified model is proposed to estimate cold point temperature. Initial process conditions, retort temperature and % solid content were the significantly affecting independent variables. A model was developed using combination of vegetable solids and water, which was then validated using four traditional Indian vegetarian products: Pulav (steamed rice with vegetables), Sambar (south Indian style curry containing mixed vegetables and lentils), Gajar Halawa (carrot based sweet product) and Upama (wheat based snack product). The predicted and experimental values of temperature profile matched with ±10 % error which is a good match considering the food was a multi component system. Thus the model will be useful as a tool to reduce number of trials required to optimize retorting of various Indian traditional vegetarian foods.

The deterioration of the food situation in the Third World and the capitalist system.

Feder, E

Hunger and malnutrition are today associated with the capitalist system. The evidence points to a further deterioration of the food situation in the Third World in the foreseeable future, as a result of massive capital and technology transfers from the rich capitalist countries to the underdeveloped agricultures operated by trans-national concerns or private investors, with the active support of development assistance agencies such as the World Bank. Contrary to the superficial predictions of the World Bank, for example, poverty is bound to increase and the purchasing power of the masses must decline. Particular attention must be paid to the supply of staple foods and the proletariat. This is threatened by a variety of factors, attributable to the operation of the capitalist system. Among them are the senseless waste of Third World resources caused by the foreign investors' insatiable thirst for the quick repatriation of super-profits and the increasing orientation of Third World agricultures toward high-value or export crops (which are usually the same), an orientation which is imposed upon them by the industrial countries' agricultural development strategies. Even self-sufficiency programs for more staple foods, such as the ill-reputed Green Revolution, predictably cannot be of long duration.

To describe stapled 1-stage functional end-to-end intestinal anastomosis for treatment of small intestinal obstruction in dogs and evaluate outcome when the technique is performed by nonexpert surgeons after limited training in the technique. Case series. Dogs (n=30) with intestinal lesions requiring an enterectomy. Stapled 1-stage functional end-to-end anastomosis and resection using a GIA-60 and a TA-55 stapling devices were performed under supervision of senior residents and faculty surgeons by junior surgeons previously trained in the technique on pigs. Procedure duration and technical problems were recorded. Short-term results were collected during hospitalization and at suture removal. Long-term outcome was established by clinical and ultrasonographic examinations at least 2 months after surgery and from written questionnaires, completed by owners. Mean±SD procedure duration was 15±12 minutes. Postoperative recovery was uneventful in 25 dogs. One dog had anastomotic leakage, 1 had a localized abscess at the transverse staple line, and 3 dogs developed an incisional abdominal wall abscess. No long-term complications occurred (follow-up, 2-32 months). Stapled 1-stage functional end-to-end anastomosis and resection is a fast and safe procedure in the hand of nonexpert but trained surgeons. © Copyright 2011 by The American College of Veterinary Surgeons.

Traditional Malian Solid Foods Made from Sorghum and Millet Have Markedly Slower Gastric Emptying than Rice, Potato, or Pasta

Directory of Open Access Journals (Sweden)

Fatimata Cisse

Full Text Available From anecdotal evidence that traditional African sorghum and millet foods are filling and provide sustained energy, we hypothesized that gastric emptying rates of sorghum and millet foods are slow, particularly compared to non-traditional starchy foods (white rice, potato, wheat pasta. A human trial to study gastric emptying of staple foods eaten in Bamako, Mali was conducted using a carbon-13 (13C-labelled octanoic acid breath test for gastric emptying, and subjective pre-test and satiety response questionnaires. Fourteen healthy volunteers in Bamako participated in a crossover design to test eight starchy staples. A second validation study was done one year later in Bamako with six volunteers to correct for endogenous 13C differences in the starches from different sources. In both trials, traditional sorghum and millet foods (thick porridges and millet couscous had gastric half-emptying times about twice as long as rice, potato, or pasta (p < 0.0001. There were only minor changes due to the 13C correction. Pre-test assessment of millet couscous and rice ranked them as more filling and aligned well with postprandial hunger rankings, suggesting that a preconceived idea of rice being highly satiating may have influenced subjective satiety scoring. Traditional African sorghum and millet foods, whether viscous in the form of a thick porridge or as non-viscous couscous, had distinctly slow gastric emptying, in contrast to the faster emptying of non-traditional starchy foods, which are popular among West African urban consumers.

To describe the use of disposable skin staples for intestinal resection and anastomosis in dogs and report associated dehiscence and mortality rates. Retrospective evaluation of medical records of dogs that underwent intestinal resection and anastomosis using disposable skin staples between 2000 and 2014. Data regarding patient signalment, indication for surgery, location of the resection and anastomosis, number of procedures performed, evidence of peritonitis at the time of surgery, surgeon qualifications, dehiscence, and mortality were obtained from the medical records. Mortality was defined as failure to survive beyond 10 days following resection and anastomosis. The overall mortality rate of patients undergoing intestinal resection and anastomosis was 12·7% (8/63). The most common indication for resection and anastomosis was neoplasia (20/63 [31·7%]), followed by foreign body removal (19/63 [30·2%]). The overall dehiscence rate was 4·8% (3/63). No difference in mortality associated with indication for surgery, whether multiple procedures were performed, surgeon qualifications, or evidence of peritonitis at the time of surgery was identified. In this retrospective study, the overall mortality and dehiscence rates using disposable skin staples were similar to previously reported outcomes following resection and anastomosis. © 2016 British Small Animal Veterinary Association.

With the global population predicted to grow by at least 25 per cent by 2050, the need for sustainable production of nutritious foods is critical for human and environmental health. Recent advances show that specialized plant membrane transporters can be used to enhance yields of staple crops, increase nutrient content and increase resistance to key stresses, including salinity, pathogens and aluminium toxicity, which in turn could expand available arable land.

Perioperative topical nitrate and sphincter function in patients undergoing transanal stapled anastomosis: a randomized, placebo-controlled, double-blinded trial.

LENUS (Irish Health Repository)

Winter, D C

2012-02-03

PURPOSE: The use of transanal stapling devices may impair continence because of digital dilatation and\\/or instrumentation. This study assessed the effect of pharmacological dilatation of the sphincter prior to stapler insertion. METHODS: A randomized, placebo-controlled, double-blinded study of 60 patients undergoing transanal stapled anastomosis was undertaken. Consenting patients were randomly assigned to receive a single intraoperative dose of topical 0.2 percent nitroglycerin (glyceryl trinitrate) ointment or nitroglycerin-free placebo. All patients were assessed preoperatively and postoperatively by clinical methods (Wexner incontinence scores and examination), anorectal manometry by a station pull-through technique, and endoanal ultrasonography. RESULTS: Intraoperative mean (+\\/-SEM) resting pressures (mmHg) were significantly reduced by nitroglycerin compared with prenitroglycerin levels (9.9 +\\/- 0.9 vs. 50.5 +\\/- 2.7; P = 0.002) or controls (56.0 +\\/- 3.2; P = 0.001). Twenty-one of the 28 controls (75 percent) but only 4 of the 32 patients in the nitroglycerin group (12.5 percent) required digital dilatation to insert the stapling instrument ( P = 0.003). Squeeze pressures were unaltered by the intervention but mean resting pressures were higher in the nitroglycerin group postoperatively (52.9 +\\/- 3.2 - 31.6 +\\/- 1.3 = 21.3 mmHg; 95 percent confidence interval, 14-27). Incontinence scores were lower in the nitroglycerin group at the 3-month (1.1 +\\/- 0.2 vs. 4.6 +\\/- 0.3; P = 0.003) and 12-month (0.9 +\\/- 0.1 vs. 4.4 +\\/- 0.3; P = 0.002) clinic visits. CONCLUSION: Preoperative nitroglycerin dilatation protects sphincter function in patients undergoing transanal stapled anastomoses.

Major food safety episodes in Taiwan: implications for the necessity of international collaboration on safety assessment and management.

Li, Jih-Heng; Yu, Wen-Jing; Lai, Yuan-Hui; Ko, Ying-Chin

2012-07-01

The major food safety episodes that occurred in Taiwan during the past decade are briefly reviewed in this paper. Among the nine major episodes surveyed, with the exception of a U.S. beef (associated with Creutzfeldt-Jakob disease)-related incident, all the others were associated with chemical toxicants. The general public, which has a layperson attitude of zero tolerance toward food safety, may panic over these food-safety-associated incidents. However, the health effects and impacts of most incidents, with the exception of the melamine incident, were essentially not fully evaluated. The mass media play an important role in determining whether a food safety concern becomes a major incident. A well-coordinated and harmonized system for domestic and international collaboration to set up standards and regulations is critical, as observed in the incidents of pork with ractopamine, Chinese hairy crab with nitrofuran antibiotics, and U.S. wheat with malathion. In the future, it can be anticipated that food safety issues will draw more attention from the general public. For unknown new toxicants or illicit adulteration of food, the establishment of a more proactive safety assessment system to monitor potential threats and provide real-time information exchange is imperative.

Residual prolapsed piles is a problem after the stapled hemorrhoidopexy, especially in large third- or fourth-degree hemorrhoids. We have developed a method using additional traction sutures along with modified Longo's procedure to manage this problem. From January 2005 to October 2005, 30 consecutive patients with symptomatic third- or fourth-degree hemorrhoids who underwent the modified Longo's stapled hemorrhoidopexy with additional traction sutures in a single institution were collected. The demographics, postoperative pain score, surgical features, outcomes, and early and late complications were recorded. All patients were followed for a mean duration of 8.8 (range, 4-15) months. Thirty patients (17 males) with a mean age of 45 (range, 27-63) years were identified. The mean postoperative pain score on the morning of the first postoperative day was 2.8 (range, 1-4). The mean duration of operation was 30.7 (range, 25-37) min. The mean duration of hospital stay was 2 (range, 1-3) days. The mean days for patients to resume normal work was 6.7 (range, 4-9) days. No other procedure-related complications occurred in all patients. There was no early complication except for fecal urgency found in one patient during the first postoperative days. Regarding the late complications, no residual prolapsed piles, persistent anal pain, incontinence, anal stenosis, or recurrent symptoms were found. Our preliminary experiences indicated that this modified procedures truly contributed to reduce the residual internal hemorrhoids and maintained the benefits of stapled hemorrhoidopexy. Randomized trial and long-term follow-up warrant to determine possible surgical and functional outcome.

[Folic acid fortified foods available in Spain: types of products, level of fortification and target population groups].

2009-01-01

Folic acid is a potentially relevant factor in the prevention of a number of pathologies (congenital abnormalities, cardiovascular disease, colorectal cancer and neurocognitive decline). This has led to the introduction of different strategies in order to increase folate intake: nutritional education, pharmacological supplementation and mandatory or voluntary fortification of staple foods with folic acid. In Spain there is a growing number of folic acid fortified products on a voluntary basis, but there is also a lack of reliable data to assess their impact on the population's dietary folate intakes. To gather a better knowledge of folic acid food fortification practices in Spain. A Food Composition Database was developed using data from a market study. Also, previously published data of unfortified staple foods from Food Composition Tables was reviewed. The Database included 260 folic acid fortified food items and it was periodically updated. Food groups included were primarily "Cereals and derivatives" (52%) followed by "Dairy products". Most of these foodstuffs lacked a target population for their consumption (37%) or were aimed at "Weight control" (28%) and "Children" (23%), but only 2% targeted women at a reproductive age. Number of unfortified foods included was 690. Fortification levels declared by manufacturers ranged between 15 and 430% of the Recommended Dietary Allowances (RDA) for folic acid per 100 g/ml, and simultaneous addition of B6 and B12 vitamins was observed in 75% of the products. Currently, Spain market offers a significant number of folic acid fortified products on a voluntary basis and at a level > or = 15% of the RDA per 100 g/ml or serving declared by manufacturers.

Ingestion of food allergens present in maternal milk during breastfeeding has been hypothesized as a gateway to sensitization to food; however, this process could develop during pregnancy, as the maternal-fetal interface develops a Th2- and Treg-mediated environment to protect the fetus. We hypothesized that in these surroundings, unborn children are exposed to food allergens contained in the mother's diet, possibly giving rise to first sensitization. The presence of allergens in utero was studied by analyzing amniotic fluid (AF) samples in two different stages of pregnancy: at 15-20 weeks and after delivery at term. An antibody microarray was developed to test for the most common food allergens. The array detects the presence of ten allergens from milk, fruit, egg, fish, nuts, and wheat. AF from 20 pregnant women was collected: eight after delivery at term and 12 from women who underwent diagnostic amniocentesis between weeks 15 and 20 of gestation. The presence of allergens was detected in all samples. Samples from amniocentesis had a higher allergen concentration than samples after delivery at term. We demonstrated the presence of intact major food allergens in AF samples. This early contact could explain subsequent sensitization to foods never eaten before. © 2016 John Wiley & Sons A/S.

There are >25,000 Supplemental Nutrition Assistance Program (SNAP)-authorized dollar stores throughout the United States; many are located in lower-income neighborhoods and provide an accessible food and beverage source for area residents. The purpose of this research was to determine the percent of food deserts within 16 counties in North Carolina that include a SNAP dollar store; examine the types of foods and beverages at SNAP dollar stores in these counties; test whether the foods and beverages offered vary by SNAP dollar store chain; and test whether the foods and beverages available differ by rural and urban location. This cross-sectional study used a combination of publicly available data and primary data to investigate the research questions. Secondary data sources were obtained from the US Department of Agriculture's SNAP retailer locator, the US Census, and the US Department of Agriculture's Food Access Research Atlas. Availability of foods and beverages was assessed among a sample of 90 SNAP dollar stores in 16 counties in southern and western sections of North Carolina. Data were collected in June 2014. About half (52%) of the food deserts in the research area included a SNAP dollar store. Most of the sampled stores sold healthier food staples, such as frozen meats, brown rice, 100% whole-wheat bread, and dried beans. None of the stores sold fresh fruits or vegetables. Some of the foods and beverages offered (eg, frozen fruit, frozen unseasoned vegetables, nonfat or low-fat milk, frozen ground beef) varied by SNAP dollar store chain. The foods and beverages offered did not differ by rural or urban county location. SNAP dollar stores offer a number of healthy food staples; however, they do not sell fresh fruits or vegetables. Further food environment research should include dollar stores. Copyright © 2016 Academy of Nutrition and Dietetics. Published by Elsevier Inc. All rights reserved.

Effects of Climate Change on the Yield and Cropping Area of Major Food Crops: A Case of Bangladesh

Directory of Open Access Journals (Sweden)

Md. Ruhul Amin

2015-01-01

Full Text Available The crops that we grow for food need specific climatic conditions to show better performance in view of economic yield. A changing climate could have both beneficial and harmful effects on crops. Keeping the above view in mind, this study is undertaken to investigate the impacts of climate change (viz. changes in maximum temperature, minimum temperature, rainfall, humidity and sunshine on the yield and cropping area of four major food crops (viz. Aus rice, Aman rice, Boro rice and wheat in Bangladesh. Heteroskedasticity and autocorrelation consistent standard error (HAC and feasible generalized least square (FGLS methods were used to determine the climate-crop interrelations using national level time series data for the period of 1972–2010. Findings revealed that the effects of all the climate variables have had significant contributions to the yield and cropping area of major food crops with distinct variation among them. Maximum temperature statistically significantly affected all the food crops’ yield except Aus rice. Maximum temperature also insignificantly affected cropping area of all the crops. Minimum temperature insignificantly affected Aman rice but benefited other three crops’ yield and cropping area. Rainfall significantly benefitted cropping area of Aus rice, but significantly affected both yield and cropping area of Aman rice. Humidity statistically positively contributed to the yield of Aus and Aman rice but, statistically, negatively influenced the cropping area of Aus rice. Sunshine statistically significantly benefitted only Boro rice yield. Overall, maximum temperature adversely affected yield and cropping area of all the major food crops and rainfall severely affected Aman rice only. Concerning the issue of climate change and ensuring food security, the respective authorities thus should give considerable attention to the generation, development and extension of drought (all major food crops and flood (particularly Aman

The aim of this survey was to investigate the level of contamination of the most consumed foods in China with 16 rare earth elements (REEs), and to provide the basic data for establishing and revising food safety standards for REEs. Sixteen REEs in foods were measured by inductively coupled plasma-mass spectrometry (ICP-MS) in the labs of the Centers for Disease Control and Prevention of four provinces and two municipalities, during 2009-2010. 1 231 samples were analyzed and 19 121 concentration data of 16 REEs were collected. The REEs levels in the investigated foods varied significantly. The concentrations of cerium (Ce), dysprosium (Dy), yttrium (Y), lanthanum (La), and neodymium (Nd) were relatively high, while the remaining eleven REEs were at low levels. The mean values of total rare earth element oxides (REOs) in cereals, fresh vegetables, fresh aquatic products, fresh meats and eggs varied from 0.052 mg/kg to 0.337 mg/kg. 16 REEs in the major foods were at very low contamination levels in the investigated regions.

Objective: To study the influence of diet and behavior related factors on the peripheral blood triglyceride levels in adults, through a cross-sectional survey. Methods: The current study included 13 434 subjects without histories of major chronic diseases from a population-based cross-sectional survey: the 2010 Metabolic Syndrome Survey in Zhejiang Province. A generalized linear model was used to investigate the influence of diet/behavior-related factors on the peripheral blood triglyceride levels. Results: Mean TG of the sample population appeared as (1.36±1.18) mmol/L. The proportions of elevated TG and marginally elevated TG were 10.3% and 11.0% respectively, with statistically significant difference seen between males and females ( χ (2)=44.135, P smoking, alcohol-intake, meat, fruit and water intake in male population from this study. However, in females, the intake of aquatic product and physical exercise showed statistically significant differences. After controlling for other variables, factors as age, drinking, staple food and aquatic products showed positive influence on TG, while milk presented negative influence on TG. Through interaction analysis, fruit and meat intake in males and staple food in females showed positive influence on TG, when compared to the reference group. Conclusion: Hyperglyceridemia appeared as one of the major metabolic abnormities in Zhejiang province. Programs on monitoring the alcohol, staple food and meat intake should be priority on intervention, in the communities.

To verify if in large haemorrhoidal prolapse (independently from the degree) in patients with no symptoms of obstructed defaecation syndrome, the use of a stapled hemorrhoidopexy variant, comprising a double stapler haemorrhoidopexy (DSH), makes it possible to reduce the percentage of failures or relapses and to standardise an objective intraoperative parameter for the purpose of quantifying internal prolapses which can then be used as a guide in determining the type of treatment to be provided. Between June 2003 and June 2004, 353 patients were treated for haemorrhoidal prolapse. The patients suffering from large haemorrhoidal prolapse occupying more than half of the length of the anal dilator were intraoperatively selected for DSH. Eighty-three patients (23.5%) underwent a DSH. The degrees of the large haemorrhoidal prolapse intraoperatively selected for DSH were sub-divided as follows: 7.2% (second), 24% (third) and 68.6% (fourth). The follow-up period was 48 months. There were three cases (3.6%) of residual illnesses and five cases (6%) of a relapse. The following complications were recorded: urgency at <3 months (7.2%), haemostasis revisions (2.4%) and spontaneously draining anterior haematoma (1.2%). The results of the 270 haemorrhoidal prolapse (38 second degree, 159 third degree and 130 fourth degree) treated with the procedure for prolapse and haemorrhoids were: nine (3.3%) residual illness and 12 (4.44%) relapse illness. The following complications were recorded: urgency at <3 months (6.6%), haemostasis revisions (2.5%) and spontaneously draining anterior haematoma (0.7%). The intraoperative selection criterion was both efficacious and reproducible. This variant technique, which can be used in large haemorrhoidal prolapses, could allow us to further improve the quality of treatment for haemorrhoidal conditions using stapled haemorrhoidopexy, without increasing the complications.

Local postoperative care and burn wound management can present with a certain degree of difficulty in the pediatric population. While the use of skin staples as a method of skin graft fixation is a well-known, rapid and simple method, their removal can be painful and may necessitate some sedation or even general anesthesia. We studied in this article the advantages and economic value of using the cyanoacrylate glue as a fixation method for skin grafts. A comparative study was carried out from 2012 to 2016. Hundred and eighteen infants with burns up to 5% of total body surface area were included in the study. Seventy-two infants had split thickness skin grafts fixed with skin staples. Forty-six infants had split thickness skin grafts fixed with cyanoacrylate glue. We compared the quality of graft, the sedation used during the first postoperative dressing, the length of hospital stay, the amount of glue used and the presence of complications. There is a difference between the two groups studied in terms of age and total burn surface area. The rate of graft take was 100% in both groups. The first postoperative dressing was carried out without the use of powerful analgesia in the cyanoacrylate group, while it was necessary to use general anesthesia in 64% of the skin staples group. The average length of stay in hospital after skin grafting was 4.9 days for the cyanoacrylate glue versus 6.5 days in the skin staples group. No complications were noted in the 2 groups. The use of cyanoacrylate glue allows rapid fixation of skin grafts and avoid general anesthesia for postoperative cares. Subsequently the length of hospital stay is reduced within 25%. The medico-economic value of glue protocol is highly significant compared to skin staples, while having similar good results and without significant problems. Copyright © 2017 Elsevier Masson SAS.

The Major Trends of Food Consumption in Hungary

Directory of Open Access Journals (Sweden)

Amelita Kata Gódor

2016-12-01

Full Text Available In the beginning of the 20th century the food consumption levels were much lower than later in the century, when food production increased as well. The selection of foodstuffs became wider and we can observe the modernisation of nutrition principles too, which both had a positive impact on consumption. The variety of food was also affected by the increasing life expectancy. The emergence of more modern ways in food consumption is halted not only by the traditions but by the fact that healthier foods are more expensive than fat or cereal prices. There is a significant correlation between the income levels and the quality of consumed food, as it can be observed that in different regions in Hungary. My aim was also to investigate the change in consumer behaviour in parallel with the increase of income levels; to see which sort of foods are preferred by the wealthier, and which are preferred by the ones with less income. It is also important to analyse the economic and social indicators on regional and other spatial levels and to compare them with food consumption. The annual net income per capita is usually higher in more developed regions than in the less developed ones. Therefore, the expenditure spent on better quality and more expensive food products is also higher. Similarly, in the case of the population there are differences in consumer habits according to purchasing power. For instance, for people with higher income one of the most important factors is to buy healthy and high quality food, but for the ones with lower income it can be a struggle only to find food in sufficient quantities, and quality cannot be as much of an issue. In the consumer basket, foodstuff accounts for approximately one-third of the overall expenditure. In this study I analysed the annual expenditure of Hungary’s population on foodstuffs and the annual quantity of food consumed by households per capita on a regional level between 2010 and 2013.

Food security is an important issue that is of concern for all countries around the world. There are many factors which may cause food insecurity including increasing demand, shortage of supply, trade condition, another countries' food policy, lack of money, high food and oil prices, decelerating productivity, speculation, etc. The food self-sufficiency ratio of Taiwan is only 30.6% weighted by energy in 2007. Total agriculture imports and cereals have increased significantly due to the expansion of livestock and fishery industries and improve living standard. The agriculture sector of Taiwan is facing many challenges, such as: low level of food self-sufficiency, aging farmers, large acreage of set-aside farmlands, small scale farming, soaring price of fertilizers, natural disasters accelerated by climate change, and rapid changes in the world food economy. To cope with these challenges, the present agricultural policy is based on three guidelines: "Healthfulness, Efficiency, and Sustainability." A program entitled "Turning Small Landlords into Large Tenants" was launched to make effective use of idle lands. Facing globalization and the food crisis, Taiwan will secure stable food supply through revitalization of its set-aside farmlands and international markets, and provide technical assistance to developing countries, in particular for staple food crops.

Full Text Available Background: One way to diminish protein malnutrition in children is by enriching cereal-based flours for the manufacturing of maize tortillas, wheat flour tortillas, and yeast-leavened breads, which are widely consumed among low socio-economic groups. Objective: The aim was to determine and compare the essential amino acid (EAA scores, protein digestibility corrected amino acid scores (PDCAAS, and in vivo protein quality (protein digestibility, protein efficiency ratio (PER, biological values (BV, and net protein utilization (NPU values of regular versus soybean-fortified maize tortillas, yeast-leavened bread, and wheat flour tortillas. Design: To comparatively assess differences in protein quality among maize tortillas, wheat flour tortillas, and yeast-leavened breads, EAA compositions and in vivo studies with weanling rats were performed. The experimental diets based on regular or soybean-fortified food products were compared with a casein-based diet. Food intake, weight gains, PER, dry matter and protein digestibility, BV, NPU, and PDCAAS were assessed. The soybean-fortified tortillas contained 6% of defatted soybean flour, whereas the yeast-leavened bread flour contained 4.5% of soybean concentrate. Results: The soybean-fortified tortillas and bread contained higher amounts of lysine and tryptophan, which improved their EAA scores and PDCAAS. Rats fed diets based on soybean-fortified maize or wheat tortillas gained considerably more weight and had better BV and NPU values compared with counterparts fed with respective regular products. As a result, fortified maize tortillas and wheat flour tortillas improved PER from 0.73 to 1.64 and 0.69 to 1.77, respectively. The PER improvement was not as evident in rats fed the enriched yeast-leavened bread because the formulation contained sugar that decreased lysine availability possibly to Maillard reactions. Conclusions: The proposed enrichment of cereal-based foods with soybean proteins greatly

Nutrient intake was surveyed by the total food duplicate method in 49 adult ethnically Malay women (at the ages of 18 to 47 years and mostly at 30-39 years) working in Kuala Lumpur, Malaysia. Simultaneously, hematological examinations, serum biochemistry, anthropometry and clinical examination were conducted. Nutrient intakes were estimated in reference to the weight of each food item and the standard food composition tables. Lunch was the most substantial meal of the day with rice as a staple food. Compared with the Recommended Dietary Allowance (RDA) values, daily intakes of energy (1,917 kcal as an arithmetic mean), protein (62.2 g), vitamin B1 (0.83 mg) and vitamin B2 (1.18 mg) were sufficient, but intakes of minerals [i.e., calcium (347.8 mg) and iron (12.5 mg)] and some vitamins [i.e., vitamin A (equivalent to 627 micrograms retinol) and niacin (7.84 mg)] were less than RDA. When evaluated on an individual basis, the prevalence of those who took less than 80% RDA was highest for iron (92%), followed by niacin (80%), calcium (57%) and vitamin A (57%). The presence of 7 hypohemoglobinemia cases may be related to the insufficient iron intake. Overweight cases (14 women) were also detected, the prevalence of which increased at advanced ages. Lipid intake was rather high (28% of total food on energy basis), for which the major source was plants with limited contribution from fish/shellfish.

2015-02-01

Full Text Available Great progress has been made over the past decade with respect to the application of biotechnology to generate nutritionally improved food crops. Biofortified staple crops such as rice, maize and wheat harboring essential micronutrients to benefit the world’s poor are under development as well as new varieties of crops which have the ability to combat chronic disease. This review discusses the improvement of the nutritional status of crops to make a positive impact on global human health. Several examples of nutritionally enhanced crops which have been developed using biotechnological approaches will be discussed. These range from biofortified crops to crops with novel abilities to fight disease. The review concludes with a discussion of hurdles faced with respect to public perception, as well as directions of future research and development for nutritionally enhanced food crops.

2011-12-01

This study evaluated the early results (with particular reference to complications) of stapled transanal rectal resection (STARR) carried out using the CCS-30 Contour® Transtar™ device. The procedure was performed in a single centre on patients with obstucted defecation caused by rectocele or rectal intussusception. From July 2007 to February 2009, 133 patients were treated. Preoperatively, all underwent clinical examination, transanal ultrasonography, anorectal manometry and cinedefaecography. Obstructed defaecation syndrome was assessed using the Cleveland Clinic Constipation Score (CCC-S). Early postoperative complications and those occurring within 6 months were recorded. The median follow-up period was 19 (range 12-30) months. The mean ± standard deviation preoperative CCC-S of 19.4 ± 7.1 decreased to 10.1 ± 9.0 postoperatively. The early complication rate was 15.7% and included rectovaginal fistula (n = 1), rectal perforation (n = 1), posterior dehiscence (n = 4), further surgery for retained staples (n = 2), postoperative bleeding (n = 2) and postoperative impaired continence (n = 11). STARR using the Contour Transtar device seems to be effective for treating obstructed defaecation. However, serious complications may occur. © 2011 The Authors.

2011-07-01

Full Text Available Bariatric surgery has become an integral part of morbid obesity treatment with well-defined indications. Some complications, specific or not, due to laparoscopic sleeve gastrectomy (LSG procedure have recently been described. We report a rare complication unpublished to date: a nasogastric section during great gastric curve stapling. A 44-year-old woman suffered of severe obesity (BMI 36.6 kg/m2 with failure of medical treatments for years. According to already published technique, a LSG was performed. Six hours postoperatively, a nurse removed the nasogastric tube according to the local protocol and the nasogastric tube was abnormally short, with staples at its extremity. Surgery was performed with peroperative endoscopy. In conclusion, this is the first publication of a nasogastric section during LSG. Therefore we report this case and propose a solution to prevent its occurrence. To avoid this kind of accident, we now systematically insert the nasogastric tube by mouth through a Guedel cannula. Then, to insert the calibrating bougie, we entirely withdraw the nasogastric tube.

Exact mechanism of causation of chronic kidney disease of unknown etiology (CKDu) in Sri Lanka is not described to date, despite the identification of possible multiple risk factors. Questions have been raised as to why only some are affected while others remain intact, though they are inhabitants of the same locality. Comparative studies were carried out, assessing urinary β2 microglobulin (β2m) and the dietary patterns of CKDu patients and age sex matched non-CKDu subjects. Urinary β2m levels of spot urine samples were analyzed using the Enzyme-linked Immunosorbent assay (ELISA) and dietary patterns were studied using twenty four hour dietary recalls and frequency consumption of foods of animal origin performed on three occasions at six months intervals within a period of one and half years. The mean urinary β2m level of CKDu patients from Medawachchiya was significantly (pCKDu subjects. The mean urinary β2m level of the non-CKDu subjects was within the reference limits for spot urine samples (0 - 0.3 μg/mL). White raw rice was the staple diet of both CKDu patients and non-CKDu subjects and the level of consumption was almost the same. The consumption of fresh water fish products of CKDu patients under high (14, 14%), moderate (36, 36%), low (26, 26%) and less (20, 20%) categories did not show significant variations (p>0.05) compared to non-CKDu subjects. Staple food in diet and the consumption pattern of CKDu patients from Medawachchiya were similar to that of non-CKDu subjects from the same area despite their urinary β2m concentration being significantly higher.

2013-01-01

Full Text Available Objective: Postoperative pouch bleeding is a rare but detrimental complication following ileal pouch surgery. It is usually self-limited, however continuous bleeding requires inter- vention. There is limited published data on its management. Design: Ileoscopy via stoma for loop ileostomy and pouchoscopy via anus for ileal pouch were performed under sedation for the purpose of diagnosis and management of postop- erative bleeding. Results: Ileoscopy demonstrated a large, long blood clot in the lumen of efferent limb, but no sign of active bleeding was identified. Pouchoscopy showed that lumen of pouch body as well as afferent limb was filled with maroon-colored liquid stool. Pouch and neo-terminal ileum mucosa was normal. Two dislodged staples at the anastomotic line with sharp tips towards the lumen were found, with activating bleeding at one site. The staples were re- moved by biopsy forceps, and active bleeding was successfully controlled by the deploy- ment of one endoclip. Conclusions: We reported the first case that postoperative pouch bleeding, which was caused by dislodged staples, was successfully managed by endoscopic removal of the staples com- bined with clipping. Resumo: Objetivo: O sangramento pós-operatório da bolsa ileal é uma complicação rara, mas prejudi- cial após abordagem cirúrgica da bolsa ileal. Esse sangramento é geralmente autolimitado, porém, requer intervenção quando contínuo. Não há dados publicados sobre o tratamento. Método: Ileoscopia através de estoma para ileostomia em alça e endoscopia via ânus para a bolsa ileal foram realizadas sob sedação para diagnóstico e tratamento do sangramento pós-operatório. Resultados: A ileoscopia demonstrou um grande e longo coágulo sanguíneo no lúmen do ramo eferente, mas nenhum sinal de sangramento ativo foi identificado. A endoscopia da bolsa ileal mostrou que os lumens do corpo da bolsa e ramo aferente estavam cheios de fe- zes líquidas de cor marrom. A

The formation of mutagens in the major cooked protein-rich foods in the US diet was studied in the Ames Salmonella typhimurium test. The nine protein-rich foods most commonly eaten in the USA--ground beef, beef steak, eggs, pork chops, fried chicken, pot-roasted beef, ham, roast beef and bacon--were examined for their mutagenicity towards S. typhimurium TA1538 after normal 'household' cooking (deep frying, griddle/pan frying, baking/roasting, broiling, stewing, braising or boiling at 100-475/sup 0/C). Well-done fried ground beef, beef steak, ham, pork chops and bacon showed significant mutagen formation. For chicken and beef steak high-temperature broiling produced the most mutagenicity, followed by baking/roasting and frying. Stewing, braising and deep frying produced little mutagen. Eggs andd egg products produced mutagens only after cooking at high temperatures (the yolk to a greater extent than the white). Commercially cooked hamburgers showed a wide range of mutagenic activity. We conclude that mutagen formation following cooking of protein-containing foods is a complex function of food type, cooking time and cooking temperature. It seems clear that all the major protein-rich foods if cooked to a well-done state on the griddle (eggs only at temperature above 225/sup 0/C) or by broiling will contain mutagens detectable by the Ames/Salmonella assay. This survey is a step towards determining whether any human health hazard results from cooking protein-rich foods. Further testing in both short- and long-term genotoxicity bioassays and carcinogenesis assays are needed before any human risk extrapolations can be made.

Philip, Dana; Hod-Ovadia, Smadar; Troen, Aron M

2017-06-01

Food banks seeking to rescue and redistribute highly nutritious perishable foods to simultaneously alleviate food insecurity and reduce food waste often encounter practical, ethical, and political dilemmas. We present a case study of "Leket Israel," an Israeli food bank that uses an effective large-scale logistical model for the rescue and redistribution of perishable food and discuss the challenges and solutions it offers. The organization operates in a rich country plagued with poverty and inequality, where the government passively encourages nongovernmental organizations to respond to the serious and growing problem of food insecurity. Operating under a business-to-business model, Leket Israel distributes food via intermediary nonprofit organizations (NPOs), enriching the food they provide with fresh produce. Food is obtained through an Agricultural Gleaning project, Self-Growing Farm project, and Meal Rescue project. The partnering NPOs then distribute the food to people in need. Although the rescue and redistribution of highly perishable food is more costly and complex than acquiring, storing, and distributing dried and staple foods and it requires specialized knowledge and infrastructure in order to maintain rigorous safety standards, it improves the nutritional quality of the aid. In 2015, Leket Israel distributed 15 217 389 kg of food, 90% of which was fruit and vegetables, to 180 partnering NPOs nationwide, reaching an estimated 175 000 recipients. "Leket Israel" offers a valuable model that can be studied and emulated by international nutrition scientists, practitioners, and policy makers who are seeking to reduce food insecurity and food waste in other countries.

Full Text Available The subject of the study is analysis of the state of food security of the South Asian countries at the present time. The methodological basis of the study is such methods as induction and deduction, analysis and synthesis. The systematic approach to the overall study of the South Asian countries’ economy and the state of its food security in particular has become the base of this research. Historical and statistical method were used to solve the main task of the research to reveal the conditions of the region’s agricultural development and food availability and food accessibility in the region as well as to carry out an assessment of the ability of households to obtain nutritious food all year round. The author also used the comparative method to analyze the South Asian countries’ approaches to realization of food policy that has allowed to reveal the specific tools used by certain countries of the region and the common characteristics of all countries of South Asia. While selecting the research topics the author proceeded from the idea that the problem of the state of food security of the South Asian countries has not been studied for the last two decades. The research required to attract and summarize a large amount of statistical data that has been drawn from many sources including official-sites of international organizations and South Asian countries. The author also used Russian and Indian scientific journals and monographs. The article highlights the state of food security in the region in accordance with criteria offered by the FAO. The author examines the situation in the South Asian countries’ agriculture sector, its productivity, the volume of production, food waste as well as the countries’ dependency on food imports. The article also presents some information on food accessibility which is generally considered within the context of household income, food distribution systems and ability of the household to obtain food

Why Clothes Don't Fall Apart: Tension Transmission in Staple Yarns

Science.gov (United States)

Warren, Patrick B.; Ball, Robin C.; Goldstein, Raymond E.

2018-04-01

The problem of how staple yarns transmit tension is addressed within abstract models in which the Amontons-Coulomb friction laws yield a linear programing (LP) problem for the tensions in the fiber elements. We find there is a percolation transition such that above the percolation threshold the transmitted tension is in principle unbounded. We determine that the mean slack in the LP constraints is a suitable order parameter to characterize this supercritical state. We argue the mechanism is generic, and in practical terms, it corresponds to a switch from a ductile to a brittle failure mode accompanied by a significant increase in mechanical strength.

Immigrants in Sweden have on average poorer health than native Swedes, including the risk of nutritional problems. In Sweden's multicultural society there is a need for increased knowledge about eating habits in public health work within health and education. A survey of refugees from Bosnia-Herzegovina living in Sweden was undertaken to describe the choice of food and food traditions in pre-war Bosnia. The purpose was to introduce the subject of food, health and migration into public health work and develop culture-adapted food and health advice. Focus-group interviews were undertaken with a total of 20 women refugees from Bosnia-Herzegovina. Qualitative data analysis identified a large consumption of bread as a staple food with meat, vegetables, milk, cheese, legumes, egg and fish as additions. Self-sufficiency was noted with milk souring, jam making and the production of sweet fruit drinks. Home made cheese and drying or smoking of meat were common methods of food storage. In child rearing, breast-feeding for 6-8 months was most common. Home made breast milk replacements were made from semolina, rice and 'petit biscuits'. Several important factors need to be taken into account when giving culturally adapted food and health advice to Bosnian families, such as encouraging bread, vegetable and legume consumption and giving advice on substituting sweet fruit drinks for natural fruit. One should be conscious of how religious beliefs as well as socio-cultural, historical, ecological, economical and psychological influences may guide food choices.

Full Text Available Estimating polyphenol intake contributes to the understanding of polyphenols’ health benefits. However, information about human polyphenol intake is scarce, especially in the elderly. This study aimed to estimate the dietary intake and major sources of polyphenols and to determine whether there is any relationship between polyphenol intake and micronutrient intake in healthy elderly Japanese. First, 610 subjects (569 men, 41 women; aged 67.3 ± 6.1 years completed food frequency questionnaires. We then calculated their total polyphenol intake using our polyphenol content database. Their average total polyphenol intake was 1492 ± 665 mg/day, the greatest part of which was provided by beverages (79.1%. The daily polyphenol intake differed largely among individuals (183–4854 mg/day, also attributable mostly to beverage consumption. Coffee (43.2% and green tea (26.6% were the major sources of total polyphenol; the top 20 food items accounted for >90%. The polyphenol intake did not strongly correlate with the intake of any micronutrient, suggesting that polyphenols may exert health benefits independently of nutritional intake. The polyphenol intake in this elderly population was slightly higher than previous data in Japanese adults, and beverages such as coffee and green tea contributed highly to the intake.

Limiting the intake of added sugars in the diet remains a key focus of global dietary recommendations. To date there has been no systematic monitoring of the major types of added sugars used in the Australian food supply. The present study aimed to identify the most common added sugars and non-nutritive sweeteners in the Australian packaged food supply. Secondary analysis of data from the Australian FoodSwitch database was undertaken. Forty-six added sugars and eight non-nutritive sweetener types were extracted from the ingredient lists of 5744 foods across seventeen food categories. Australia. Not applicable. Added sugar ingredients were found in 61 % of the sample of foods examined and non-nutritive sweetener ingredients were found in 69 %. Only 31 % of foods contained no added sugar or non-nutritive sweetener. Sugar (as an ingredient), glucose syrup, maple syrup, maltodextrin and glucose/dextrose were the most common sugar ingredient types identified. Most Australian packaged food products had at least one added sugar ingredient, the most common being 'sugar'. The study provides insight into the most common types of added sugars and non-nutritive sweeteners used in the Australian food supply and is a useful baseline to monitor changes in how added sugars are used in Australian packaged foods over time.

Laparoscopic sleeve gastrectomy (LSG) is associated with serious complications, such as staple line (SL) leaks and bleeding. In order to prevent the occurrence of these complications, surgeons have advocated the need to strengthen the staple line. The aim of this randomized controlled study was to compare the efficacy of three different ways of strengthening of the SL in LSG in preventing surgical post-operative complications. Between April 2012 and December 2014, 600 patients (pts) scheduled for LSG were prospectively randomized into groups without SL reinforcement (group A) or with SL reinforcement including fibrin glue coverage (group B), or oversewn SL with imbricating absorbable (Monocryl™; group C) or barbed (V lock®) running suture (group D). Primary endpoints were post-operative leaks, bleeding, and stenosis, while secondary outcomes consisted of the time to perform the staple line reinforcement (SLR) and total operative time. Mean SLR operative time was lower for group B (3.4 ± 1.3 min) compared with that for groups C (26.8 ± 8.5 min) and D (21.1 ± 8.4 min) (p running suture or with fibrin glue, is an unrewarding surgical act with the sole effect of prolonging the operative time.

Early rectal stenosis following stapled rectal mucosectomy for hemorrhoids

2004-05-01

Full Text Available Abstract Background Within the last years, stapled rectal mucosectomy (SRM has become a widely accepted procedure for second and third degree hemorrhoids. One of the delayed complications is a stenosis of the lower rectum. In order to evaluate the specific problem of rectal stenosis following SRM we reviewed our data with special respect to potential predictive factors or stenotic events. Methods A retrospective analysis of 419 consecutive patients, which underwent SRM from December 1998 to August 2003 was performed. Only patients with at least one follow-up check were evaluated, thus the analysis includes 289 patients with a mean follow-up of 281 days (±18 days. For statistic analysis the groups with and without stenosis were evaluated using the Chi-Square Test, using the Kaplan-Meier statistic the actuarial incidence for rectal stenosis was plotted. Results Rectal stenosis was observed in 9 patients (3.1%, eight of these stenoses were detected within the first 100 days after surgery; the median time to stenosis was 95 days. Only one patient had a rectal stenosis after more than one year. 8 of the 9 patients had no obstructive symptoms, however the remaining patients complained of obstructive defecation and underwent surgery for transanal strictureplasty with electrocautery. A statistical analysis revealed that patients with stenosis had significantly more often prior treatment for hemorrhoids (p Conclusion Rectal stenosis is an uncommon event after SRM. Early stenosis will occur within the first three months after surgery. The majority of the stenoses are without clinical relevance. Only one of nine patients had to undergo surgery for a relevant stenosis. The predictive factor for stenosis in the patient-characteristics is previous interventions for hemorrhoids, severe postoperative pain might also predict rectal stenosis.

To compare the nutrient profile of packaged supermarket food products available in Australia and New Zealand. Eligibility to carry health claims and relationship between nutrient profile score and nutritional content were also evaluated. Nutritional composition data were collected in six major Australian and New Zealand supermarkets in 2012. Mean Food Standards Australia New Zealand Nutrient Profiling Scoring Criterion (NPSC) scores were calculated and the proportion of products eligible to display health claims was estimated. Regression analyses quantified associations between NPSC scores and energy density, saturated fat, sugar and sodium contents. NPSC scores were derived for 23,596 packaged food products (mean score 7.0, range -17 to 53). Scores were lower (better nutrient profile) for foods in Australia compared with New Zealand (mean 6.6 v. 7.8). Overall, 45% of foods were eligible to carry health claims based on NPSC thresholds: 47% in Australia and 41% in New Zealand. However, less than one-third of dairy (32%), meat and meat products (28%) and bread and bakery products (27.5%) were eligible to carry health claims. Conversely, >75% of convenience food products were eligible to carry health claims (82.5%). Each two-unit higher NPSC score was associated with higher energy density (78 kJ/100 g), saturated fat (0.95 g/100 g), total sugar (1.5 g/100 g) and sodium (66 mg/100 g; all P values<0.001). Fewer than half of all packaged foods available in Australia and New Zealand in 2012 met nutritional criteria to carry health claims. The few healthy choices available in key staple food categories is a concern. Improvements in nutritional quality of foods through product reformulation have significant potential to improve population diets.

Vegetarian diets are defined by the absence of meat and fish, but differences in the intake of other foods between meat-eaters and low or non-meat eaters are also important to document. We examined intakes of high-protein foods (meat, poultry, fish, legumes, nuts, vegetarian protein alternatives, dairy products, and eggs) and other major food groups (fruit, vegetables, bread, pasta, rice, snack foods, and beverages) in regular meat-eaters, low meat-eaters, poultry-eaters, fish-eaters, vegetarians, and vegans of white ethnicity participating in UK Biobank who had completed at least one web-based 24-h dietary assessment (n = 199,944). In regular meat-eaters, around 25% of total energy came from meat, fish, dairy and plant milk, cheese, yogurt, and eggs. In vegetarians, around 20% of energy came from dairy and plant milk, cheese, yoghurt, eggs, legumes, nuts, and vegetarian protein alternatives, and in vegans around 15% came from plant milk, legumes, vegetarian alternatives, and nuts. Low and non-meat eaters had higher intakes of fruit and vegetables and lower intakes of roast or fried potatoes compared to regular meat-eaters. The differences in the intakes of meat, plant-based high-protein foods, and other foods between meat-eaters and low and non-meat eaters in UK Biobank may contribute to differences in health outcomes.

Food intolerance is believed to be a source of frequent medical problems in ulcerative colitis (UC), which closely correlate with patients' dietary pattern. Living in an underdeveloped area of China, residents in southwestern region have diverse dietary habits. The objective of this study is to determine the prevalence of food intolerance in the UC patients in this area and to discuss some of the possible risk factors leading to the condition. Food antibodies in serum of 80 patients with active UC were determined by standard enzyme-linked immuno sorbent assay (ELISA). This study examined the risk factors contributing to high titers of food antibodies and the dietary patterns correlating with food intolerance in these demographics. 83.8% of patients (67/80) were found to be seropositive for food intolerance. Patients of female, aged between 20 to 40 and the one who tended to have a high fat diet were tested to be highly seropositive (pintolerance (p>0.05). Active UC patients in southwestern region of China have showed to be high seropositive in food intolerance, particularly in female and young patients. Dietary patterns with high in fat intake seem to have caused high prevalence of seropositivity in food intolerance. Although rice has been taken as staple food and the spicy food has been popular among citizen in this region, these foods have indicated to no effect on food intolerance in this study.

Background The optimal fixation method for the first tarsometatarsal arthrodesis remains controversial. This study aimed to develop a reproducible first tarsometatarsal testing model to evaluate the biomechanical performance of different reconstruction techniques. Methods Crossed screws or a claw plate were compared with a single or double shape memory alloy staple configuration in 20 Sawbones models. Constructs were mechanically tested in 4-point bending to 1, 2, and 3 mm of plantar displacement. The joint contact force and area were measured at time zero, and following 1 and 2 mm of bending. Peak load, stiffness, and plantar gapping were determined. Results Both staple configurations induced a significantly greater contact force and area across the arthrodesis than the crossed screw and claw plate constructs at all measurements. The staple constructs completely recovered their plantar gapping following each test. The claw plate generated the least contact force and area at the joint interface and had significantly greater plantar gapping than all other constructs. The crossed screw constructs were significantly stiffer and had significantly less plantar gapping than the other constructs, but this gapping was not recoverable. Conclusions Crossed screw fixation provides a rigid arthrodesis with limited compression and contact footprint across the joint. Shape memory alloy staples afford dynamic fixation with sustained compression across the arthrodesis. A rigid polyurethane foam model provides an anatomically relevant comparison for evaluating the interface between different fixation techniques. Clinical Relevance The dynamic nature of shape memory alloy staples offers the potential to permit early weight bearing and could be a useful adjunctive device to impart compression across an arthrodesis of the first tarsometatarsal joint.

"Population and poverty: major barriers to food accessibility" -- a panel discussion on civil society and people's participation.

Science.gov (United States)

1996-01-01

This paper summarizes conference statements on poverty and food policies that were made by parliamentary members from Malaysia, the Philippines, and India. These presentations were made after the main panel discussion on barriers to food accessibility. In Malaysia the government adopted a National Agricultural Policy in 1984. This policy encouraged increased productivity, effective use of resources, agricultural credit and incentives, and integrated pest management. Strong support was given to the food processing industry. Poverty was the main reason for food inaccessibility. Through government efforts, poverty was reduced from 16.5% in 1990 to 8.9% in 1995. The Filipino member reported that government efforts had focused on national campaigns to combat hunger and to encourage community participation. The government was forced to implement a national Plan of Action for Food Security due to increased population, environmental degradation, closing land frontiers, and the global economy. The Plan encouraged increases in productivity, price and supply stabilization, maintenance of stocks, and rice subsidies for the poor. Gender concerns were being incorporated into development programs. The Indian member linked food insecurity to world resource problems. He stated that food problems included imbalances between supply and demand, but more importantly inequalities in access to food and differences in nutritional content of food. Populations in developing countries spent a larger proportion of income on food of lesser quality and variety that contributed to nutritional deficiencies, particularly among women and children. Food insecurity was part of the cycle of poverty, hunger, low productivity, and high mortality. Poverty was the primary cause and a major consequence of hunger and chronic food insecurity. Although India increased food productivity, food insecurity remained. Multidisciplinary approaches are needed.

Maize is an important staple food consumed by millions of people in many countries. Yellow maize naturally contains carotenoids which not only provide provitamin A carotenoids but also xanthophylls, which are known to be important for eye health. This study was aimed at 1) evaluating the effect of saponification during extraction of yellow maize carotenoids, 2) determining the major carotenoids in 36 genotypes of yellow maize by high-performance liquid chromatography with a C30 column, and 3) determining the effect of cooking on the carotenoid content of yellow maize. The major carotenoids in yellow maize were identified as all-trans lutein, cis-isomers of lutein, all-trans zeaxanthin, alpha- and beta-cryptoxanthin, all-trans beta-carotene, 9-cis beta-carotene, and 13-cis beta-carotene. Our results indicated that carotenoid extraction without saponification showed a significantly higher yield than that obtained using saponification. Results of the current study indicate that yellow maize is a good source of provitamin A carotenoids and xanthophylls. Cooking by boiling yellow maize at 100 degrees C for 30 minutes increased the carotenoid concentration, while baking at 450 degrees F for 25 minutes decreased the carotenoid concentrations by almost 70% as compared to the uncooked yellow maize flour.

Many programs aim to alleviate vitamin A deficiency. Biofortification is an approach to improve provitamin A carotenoid concentrations of staple crops in some developing countries. In rural Zambia, maize accounts for the majority of energy intake. Provitamin A-biofortified (orange) maize has been released in Zambia. This study quantified food intake of Zambian children from records collected in a feeding trial in 2012 in order to compare adoption of orange maize and a new vegetable (green beans) with white maize and traditional foods. One hundred thirty-six children with a mean age of 71.5 +/- 6.9 months were fed three meals a day for 6 days a week for 15 weeks at four feeding centers. Breakfast consisted of maize porridge, and lunch and dinner were stiff porridge (nshima) with various side dishes (relishes). There were three treatment groups, which received orange maize and placebo oil, white maize and placebo oil, or white maize and a daily vitamin A supplement. Food was weighed before and after consumption. Nutritionists were trained to interview the children's caregivers about the previous day's intake using dietary recalls. Nine dietary recalls for each child were recorded and analyzed. Total food intake did not differ among the groups (p = .31) and energy intakes on Sundays (kcal) were below recommendations. Nshima intake was lower in the orange-maize group (p = .008), largely due to a genotype effect. Intakes of relish, green bean, and porridge did not differ among the groups (p > .19). Dietary recalls revealed that children living in sites closer to the main road consumed more on Sundays than children living about 8 km from the main road, but less in the evenings when children were off site. The intakes of energy of these Zambian children were low. Implementation and adoption of new and biofortified foods is possible with promotion.

High dietary fat consumption may alter oocyte development and embryonic development. This prospective study was conducted to determine the relation between dietary fat consumption level, its food sources and the assisted reproduction parameters. A prospective study was conducted on 240 infertile women. In assisted reproduction treatment cycle, fat consumption and major food sources over the previous three months were identified. The number of retrieved oocytes, metaphase ΙΙ stage oocytes numbers, fertilization rate, embryo quality and clinical pregnancy rate were also determined. The data were analyzed using multiple regression, binary logistic regression, chi-square and t-test. The p-value of less than 0.05 was considered significant. Total fat intake adjusted for age, body mass index, physical activity and etiology of infertility was positively associated with the number of retrieved oocytes and inversely associated with the high embryo quality rate. An inverse association was observed between sausage and turkey ham intake and the number of retrieved oocytes. Also, oil intake level had an inverse association with good cleavage rate. The results revealed that higher levels of fat consumption tend to increase the number of retrieved oocytes and were adversely related to embryonic development. Among food sources of fat, vegetable oil, sausage and turkey ham intake may adversely affect assisted reproduction parameters.

Full Text Available Background: Dietary intake of macronutrient and foods is considered crucial to decrease the risk of diet-related non-communicable diseases. Methods: The aim of this study was to describe the intake of major food groups and macronutrients in a random sample of 1838 southern Italian adults. Results: No significant differences of macronutrient consumption between sexes were found. By contrast, younger individuals had significantly higher intake of animal protein than older ones. Men reported consuming significantly more total processed meats and less eggs than women; egg consumption significantly increased by age groups. Significantly lower intake of fruit in the younger age group compared to older ones was found. Various patterns of correlation between food groups were described. More than half of individuals reached the suggested recommendations for carbohydrate and fiber intake, and about two-thirds met the recommendations for total protein and cholesterol intake, while only a minority met for total fat intake. Total and plant protein, monounsaturated and omega-6 fatty acids, were significantly inversely related with BMI (body mass index, while trans fatty acids and cholesterol were directly correlated. A direct association with unprocessed meats and an inverse association with processed meats was also found. Conclusions: The overall findings suggest that relatively healthy dietary habits are common in southern Italy.

The development of constrained peptides for inhibition of protein-protein interactions is an emerging strategy in chemical biology and drug discovery. This manuscript introduces a versatile, rapid and reversible approach to constrain peptides in a bioactive helical conformation using BID and RNase S peptides as models. Dibromomaleimide is used to constrain BID and RNase S peptide sequence variants bearing cysteine (Cys) or homocysteine ( h Cys) amino acids spaced at i and i + 4 positions by double substitution. The constraint can be readily removed by displacement of the maleimide using excess thiol. This new constraining methodology results in enhanced α-helical conformation (BID and RNase S peptide) as demonstrated by circular dichroism and molecular dynamics simulations, resistance to proteolysis (BID) as demonstrated by trypsin proteolysis experiments and retained or enhanced potency of inhibition for Bcl-2 family protein-protein interactions (BID), or greater capability to restore the hydrolytic activity of the RNAse S protein (RNase S peptide). Finally, use of a dibromomaleimide functionalized with an alkyne permits further divergent functionalization through alkyne-azide cycloaddition chemistry on the constrained peptide with fluorescein, oligoethylene glycol or biotin groups to facilitate biophysical and cellular analyses. Hence this methodology may extend the scope and accessibility of peptide stapling.

Nutrition by design: a review of biotechnology in functional food

2016-02-01

Full Text Available Medical institutions in industrial and developing countries are increasingly turning to functional foods as intervention in chronic disease. Advances in genetic engineering have provided methods of purposefully designing functional foods and bioactive compound-producing organisms. This literature review examines the recent history of biotechnological applications in functional food, the state of bioagricultural engineering for high-value compound production, and the challenges that developers face in promulgatingfunctional foods from biotechnological sources. Based on the literature reviewed, it is predicted that adding biotechnologically-produced compounds will be more successful in producing novel functional foods. Conclusion: Current functional food application is frequently hampered by a dearth of foods suitable to the purpose. The concurrent advent of biotechnology means that producers and clinicians are not constrained by limited and precarious natural development. Biotechnology has already produced altered dietary staples that can safely induce real health benefits, but the social approval of genetically modified foodstuffs is inconsistent at best. Modifying microalgae to produce micro and macronutrients, for harvest and incorporation into functional food products, provides the ideal specificity and reliability for bioactive compound use. However, its application in biomedical science is impeded by technical difficulty. It remains to be seen if microorganism engineering willbe able to meet the needs of its many stakeholders, including the functional food community. Nonetheless,the prospect of a flourishing functional food market, and the healthier population it will bring about, certainly makes it worth a try.

While fortification of staple foods and condiments has gained enormous global traction, poor performance persists throughout many aspects of implementation, most notably around the critical element of regulatory monitoring, which is essential for ensuring foods meet national fortification standards. Where coverage of fortified foods is high, limited nutritional impact of fortification programs largely exists due to regulatory monitoring that insufficiently identifies and holds producers accountable for underfortified products. Based on quality assurance data from 20 national fortification programs in 12 countries, we estimate that less than half of the samples are adequately fortified against relevant national standards. In this paper, we outline key findings from a literature review, key informant interviews with 11 fortification experts, and semi-quantitative surveys with 39 individuals from regulatory agencies and the food fortification industry in 17 countries on the perceived effectiveness of regulatory monitoring systems and barriers to compliance against national fortification standards. Findings highlight that regulatory agencies and industry disagree on the value that enforcement mechanisms have in ensuring compliance against standards. Perceived political risk of enforcement and poorly resourced inspectorate capacity appear to adversely reinforce each other within an environment of unclear legislation to create a major hurdle for improving overall compliance of fortification programs against national standards. Budget constraints affect the ability of regulatory agencies to create a well-trained inspector cadre and improve the detection and enforcement of non-compliant and underfortified products. Recommendations to improve fortification compliance include improving technical capacity; ensuring sustained leadership, accountability, and funding in both the private and the public sectors; and removing political barriers to ensure consistent detection of

Demand for agricultural products is an important problem in climate change economics. Food consumption will shape and shaped by climate change and emissions mitigation policies through interactions with bioenergy and afforestation, two critical issues in meeting international climate goals such as two-degrees. We develop a model of food demand for staple and nonstaple commodities that evolves with changing incomes and prices. The model addresses a long-standing issue in estimating food demands, the evolution of demand relationships across large changes in income and prices. We discuss the model, some of its properties and limitations. We estimate parameter values using pooled cross-sectional-time-series observations and the Metropolis Monte Carlo method and cross-validate the model by estimating parameters using a subset of the observations and test its ability to project into the unused observations. Finally, we apply bias correction techniques borrowed from the climate-modeling community and report results.

For many voltage-gated ion channels (VGICs), creation of a properly functioning ion channel requires the formation of specific protein-protein interactions between the transmembrane pore-forming subunits and cystoplasmic accessory subunits. Despite the importance of such protein-protein interactions in VGIC function and assembly, their potential as sites for VGIC modulator development has been largely overlooked. Here, we develop meta-xylyl (m-xylyl) stapled peptides that target a prototypic VGIC high affinity protein-protein interaction, the interaction between the voltage-gated calcium channel (Ca V ) pore-forming subunit α-interaction domain (AID) and cytoplasmic β-subunit (Ca V β). We show using circular dichroism spectroscopy, X-ray crystallography, and isothermal titration calorimetry that the m-xylyl staples enhance AID helix formation are structurally compatible with native-like AID:Ca V β interactions and reduce the entropic penalty associated with AID binding to Ca V β. Importantly, electrophysiological studies reveal that stapled AID peptides act as effective inhibitors of the Ca V α 1 :Ca V β interaction that modulate Ca V function in an Ca V β isoform-selective manner. Together, our studies provide a proof-of-concept demonstration of the use of protein-protein interaction inhibitors to control VGIC function and point to strategies for improved AID-based Ca V modulator design.

2017-12-01

The increasing global demand for natural rubber (100% increase in the last 15 years) is for most part met by Malaysia and Indonesia, and - to a lesser extent - other countries in south-east Asia and Africa. The consequent expansion of rubber plantation has often occurred at the expenses of agricultural land for staple food, particularly in southeast Asia, where most of the land suitable for agriculture is already harvested for food crops or other uses. Here we investigate the extent to which the ongoing increase in rubber production is competing with the food system and affecting the livelihoods of rural communities in the areas of production and their appropriation of natural resources, such as water. We also investigate to what extent the expansion of rubber plantations is taking place through large scale land acquisitions (LSLAs) and evaluate the impacts on rural communities. Our results show how rubber production has strong environmental, social and economic impacts. Despite their ability to bring employment and increase the average income of economically disadvantaged areas, rubber plantations may threaten the local water and food security and induce a loss of rural livelihoods, particularly when the new plantations result from LSLAs that displace semi-subsistence forms of production thereby forcing the local populations to depend on global markets.

Efforts to achieve food security, especially food self-sufficiency, face severe challenges. Intensification needs to be done in optimizing the existing land by applying integrated agriculture. One of them is by integrating agriculture and fishery aspect with implementation of minapadi. Minapadi cultivation has actually grown since a long time, but in the course of time this system Began displaced because of pesticides and chemical fertilizers. Become flagship Minapadi back in line with the increasing public awareness of the importance of sustainable environment, health, increasing demand for organic products that are free from pesticide residues which means safe for consumption. Minapadi is the answer to the fulfillment of people's need for carbohydrate and protein food. Blending the fulfillment of carbohydrates is rice as the staple food of most people with the fulfillment of animal protein from fish commodities to add nutritional value. In realizing the food security strategy is required Minapadi development. This descriptive research aims to find out various minapadi development strategies in several regions with different methods based on the literature and previous studies. The result is the formulation of minapadi development strategy in an area not necessarily can be applied in other areas.This occurs because of differences in setting criteria/ variables based on the characteristics and potential of a region, the strengths and opportunities, as well as the weaknesses and threats that the area may encounter.

Our aim was to assess whether the individual surgeon is an independent risk factor for anastomotic leak in double-stapled colorectal anastomosis after left colon and rectal cancer resection. This retrospective analysis of a prospectively collected database consists of a consecutive series of 800 patients who underwent an elective left colon and rectal resection with a colorectal, double-stapled anastomosis between 1993 and 2009 in a specialized colorectal unit of a tertiary hospital with 7 participating surgeons. The main outcome variable was anastomotic leak, defined as leak of luminal contents from a colorectal anastomosis between 2 hollow viscera diagnosed radiologically, clinically, endoscopically, or intraoperatively. Pelvic abscesses were also considered to be an anastomotic leak. Radiologic examination was performed when there was clinical suspicion of leak. Anastomotic leak occurred in 6.1% of patients, of which 33 (67%) were treated operatively, 6 (12%) with radiologic drains, and 10 (21%) by medical treatment. Postoperative mortality rate was 2.9% for the whole group of 800 patients. In patients with anastomotic leak, mortality rate increased up to 16% vs 2.0% in patients without anastomotic leak (P leak. The surgeon was the most important factor (mean odds ratio 4.9; range 1.0 to 13.5). The variance of anastomotic leak between the different surgeons was 0.56 in the logit scale. The individual surgeon is an independent risk factor for leakage in double-stapled, colorectal, end-to-end anastomosis after oncologic left-sided colorectal resection. Copyright © 2017 Elsevier Inc.

To test Koctürk's model of dietary change among South-Asian Surinamese in the Netherlands. The model categorizes foods into staple, complementary and accessory foods and postulates that dietary change after migration begins with accessory foods while foods associated with ethnic identity (staple foods) change at a slower rate. Cross-sectional data from the HELIUS study. Dietary intake was assessed with an FFQ. Acculturation was based on social contacts and sense of belonging and was translated into four strategies of acculturation: assimilation, integration, separation and marginalization. Other indicators of acculturation included residence duration, age at migration and migration generation status. Amsterdam, the Netherlands. Participants of Dutch (n 1456) and South-Asian Surinamese origin (n 968). Across all acculturation strategies, South-Asian Surinamese participants reported significantly higher intakes of rice (staple food) and chicken (complementary food) and significantly lower intakes of red meat and vegetables (complementary foods) and cookies and sweets (accessory food) than Dutch participants. Men, second-generation and assimilated South-Asian Surinamese were inclined towards Dutch foods such as potato, pasta and red meat. Accessory foods like fruits showed variation across acculturation strategies. Consistent with the Koctürk model, the intake of staple foods was stable among South-Asian Surinamese irrespective of acculturation strategy while the intake of accessory foods like fruit varied. Contrary to expectations, South-Asian Surinamese showed consistently high intakes of complementary foods like chicken and fish irrespective of acculturation strategy. Public health practitioners should take into consideration the complex and dynamic nature of dietary acculturation.

Phenolic-enriched foods: sources and processing for enhanced health benefits.

Science.gov (United States)

McDougall, Gordon J

2017-05-01

Polyphenols are ubiquitous secondary products present in many plant foods. Their intake has been associated with health benefits ranging from reduced incidence of CVD, diabetes and cancers to improved neurodegenerative outcomes. Major dietary sources include beverages such as coffee, teas and foods such as chocolate. Fruits are also major sources and berries in particular are a palatable source of a diverse range of polyphenol components. There are a number of ways that polyphenol uptake could be increased and healthier polyphenol-rich foods could be produced with specific compositions to target-specific health effects. Firstly, we could exploit the genetic diversity of plants (with a focus on berries) to select varieties that have enhanced levels of specific polyphenols implicated in disease mitigation (e.g. anthocyanins, tannins or flavonols). Working with variation induced by environmental and agronomic factors, modern molecular breeding techniques could exploit natural variation and beneficially alter polyphenol content and composition, although this could be relatively long term. Alternatively, we could employ a synthetic biology approach and design new plants that overexpress certain genes or re-deploy more metabolic effort into specific polyphenols. However, such 'polyphenol-plus' fruit could prove unpalatable as polyphenols contribute to sensorial properties (e.g. astringency of tannins). However, if the aim was to produce a polyphenol as a pharmaceutical then 'lifting' biosynthetic pathways from plants and expressing them in microbial vectors may be a feasible option. Secondly, we could design processing methods to enhance the polyphenolic composition or content of foods. Fermentation of teas, cocoa beans and grapes, or roasting of cocoa and coffee beans has long been used and can massively influence polyphenol composition and potential bioactivity. Simple methods such as milling, heat treatment, pasteurisation or juicing (v. pureeing) can have notable

Water, food, and population -- a panel discussion.

Science.gov (United States)

1996-01-01

This paper summarizes a conference panel discussion among parliamentarians and researchers on water and food supplies and population growth in Asia. The Western Samoa legislator urged delegates to be aware of human development that was no more than the promotion of values associated with a market economy. Samoans increased their per capita caloric consumption. The food supply is provided locally, and 90% of exports are food products. Food security would be jeopardized by a fivefold increase in population. Samoan human development indicators were relatively good for a developing country. However, the country was still ranked as a low-income, food-deficit country. The Pakistani delegate explained that Pakistan's agriculture used the largest, continuous irrigation system in the world. However, the system operated inefficiently. There was concern that future high population growth would jeopardize food security. Another barrier was institutional mismanagement of irrigation and reliance on imports for staple items. Agricultural productivity must increase to meet the increased needs of continued population growth. All available land is currently under cultivation. Future strategies will necessitate international cooperation and innovative and environmentally sound technology. Professor Xuan remarked that increased population growth and rising demand, decreased water quality, and changing consumption patterns were a threat to water supplies. Sustainable increases in food production would entail better water management: reforestation to reduce and prevent water runoff, better technological exploitation of rain water, and more efficient use of irrigation systems. Better international financing schemes were needed for support of these policy changes. Professor Ness suggested free markets in water in order to price water at actual rates of consumption. Polluters should pay. Water management was also threatened by global warming.

The aim of this article was to investigate the food (in)security effect of household income generated from major economic activities in rural Swaziland. From a sample of 979 households, the results of a multinomial treatment regression model indicated that gender of household head, labor endowment, education, size of arable land, and location significantly influenced the households' choice of primary economic activity. Further results suggested that off-farm-income-dependent households were less likely to be food insecure when compared with on-farm-income-dependent households. However, on-farm-income-dependent households had a better food security status than their counterparts who depended on remittances and nonfarm economic activities.

Full Text Available Cash transfer (CTs is an increasingly popular social protection mechanism used by many developing countries to improve the food security and nutritional status of lower socio-economic groups. This paper is a review of the literature regarding the impact of CT programs on the food security of recipient households in the developing countries, including Iran. We looked for all original studies, performed in the developing countries and published in any language, containing at least one outcome related to food and nutritional security of the beneficiary population using Pub Med, Iran Medex, SID (Scientific Information Database, ISI (Information Sciences Institute database, INP (Iran’s Nutrition Publication Abstracts, IRANDOC and Magiran. Searches used the following terms or keywords: “household food security”, “household food insecurity” and “cash transfer” on any publication published within 1990-2015. A total of 12 studies evaluating the influence of CT programs on the recipients’ food and nutrition security were identified. CT programs have the potential to deliver a range of benefits not only through reducing extreme poverty but also by providing effective support for broader human development objectives, including better nutrition, as well as health and education outputs and outcomes. The extent to which programs can have these different impacts will depend critically on the availability of complementary services, the local context, and the specifics of program design, including the transfer value. However, findings in Iran suggest that the replacement of staple food subsidies by CT has led to a significant increase in household food insecurity (especially marginal or mild food insecurity.

The objectives of this study were to determine the levels of the major and mineral nutrients, specially of trace elements, in some food items commonly consumed in Sudan, to assess the nutritional and energy values in these items and to compare the results of this work with local and international data.To achieve these objectives, food samples analyzed were collected from different localities in Sudan, and the samples were prepared for analysis using dry ashing and wet digestion. Moisture was determined using oven and freeze dryer. Proteins were determined by kjeldahl method. Fats were determined using ether extraction. Ash contents were determined using muffle furnace. Atomic absorption spectroscopy (AAS), X-ray flourescence spectroscopy (XRF), flame photometry and colorimetry techniques were employed for determination of elemental contents. The levels of food energy, moisture, carbohydrates, proteins, fats, crude fibre and ash contents were determined in legumes, cereals, oil seeds, flour and cereals products , vegetables, fruits, milk and milk products, and oil and fats. The elemental contents (Br, Ca, Co, Cu, Fe, Mg, Mn, P, Pb, Na, Rb, Sr and Zn). The Sudanese food items analyzed were found to contain considerable ranges of nutrients as follows: Food energy was found to be in its higest value (930 calg) in oil seeds and in the lowest range in vegetables (14.9-139 cal/g dry matter). Proteins contents were the the -ighest in oil seeds (17.4-27.7 g/100g of dry matter) and devoid in oils and fats. FAts contents were in the highest value (100% of dry matter) in oils and fats and in the lowest in vegetables (0.01-0.6 g/100g). Carbohydrates were in the highest range in cereals (73-79 g/100g of dry matter) and devoid in oils and fats. For the elemental contents the most significant elements have the following average: CA, CU and Fe were higher in fruits (4709, 21 and 633 ppm, respectively) and the lower in oils and fats (25, 2 and 11 ppm, respectively).

To identify risk factors for dehiscence in stapled functional end-to-end anastomoses (SFEEA) in dogs. Retrospective case series. Dogs (n = 53) requiring an enterectomy. Medical records from a single institution for all dogs undergoing an enterectomy (2001-2012) were reviewed. Surgeries were included when gastrointestinal (GIA) and thoracoabdominal (TA) stapling equipment was used to create a functional end-to-end anastomosis between segments of small intestine or small and large intestine in dogs. Information regarding preoperative, surgical, and postoperative factors was recorded. Anastomotic dehiscence was noted in 6 of 53 cases (11%), with a mortality rate of 83%. The only preoperative factor significantly associated with dehiscence was the presence of inflammatory bowel disease (IBD). Surgical factors significantly associated with dehiscence included the presence, duration, and number of intraoperative hypotensive periods, and location of anastomosis, with greater odds of dehiscence in anastomoses involving the large intestine. IBD, location of anastomosis, and intraoperative hypotension are risk factors for intestinal anastomotic dehiscence after SFEEA in dogs. Previously suggested risk factors (low serum albumin concentration, preoperative septic peritonitis, and intestinal foreign body) were not confirmed in this study. © Copyright 2015 by The American College of Veterinary Surgeons.

Identification of major sources of energy in the diet helps to implement dietary recommendations to reduce obesity. To determine the food sources of energy consumed by Brazilians, we used the traditional method of ranking energy contribution of selected food groups and also compared days with and without consumption of specific food groups. Analysis was based on two non-consecutive days of dietary record from the Brazilian National Dietary Survey, conducted among 34,003 Brazilians (aged 10 years or more), taking into account the complex design of the survey. Comparison of days with and without consumption gave more consistent results, with sweets and cookies as the most important contributors to energy intake, increasing 992 kJ/d (95% CI 883, 1096) for those days when consumption of cakes, cookies and desserts was reported compared to days without their consumption. Savoury snacks, cheese and sugar-sweetened beverages (SSB) also increase energy intake by about 600 kJ. The only group associated with decreased energy intake was vegetable (-155 kJ; 95% CI -272, -37). Consumption of beans, milk and fruits increased the energy intake by about 210 kJ. In total, the mean energy intake of the group was 8000 kJ. Except for the consumption of vegetables, all of the other ten food groups analysed were associated with increased energy intake. Sweets and cookies may increase the energy intake by 12% and SSB by 7%, indicating that these two groups are major targets for improving healthy eating by reducing energy intake; whereas vegetable intake is associated with the reduction of energy content of the diet.

To examine the associations between financial, physical and transport conditions that may restrict food access (which we define as food security indicators) and the purchase of fast foods and nutritious staples such as bread and milk. Multilevel logistic and multinomial regression analysis of cross-sectional survey data to assess associations between the three indicators of food insecurity and household food shopping adjusted for sociodemographic and socio-economic variables. Random selection of households (n 3995) from fifty Census Collector Districts in Melbourne, Australia, in 2003. The main food shoppers in each household (n 2564). After adjustment for confounders, analysis showed that a greater likelihood of purchasing chain-brand fast food on a weekly basis compared with never was associated with running out of money to buy food (OR = 1·59; 95 % CI 1·08, 2·34) and reporting difficulties lifting groceries (OR = 1·77; 95 % CI 1·23, 2·54). Respondents without regular access to a car to do food shopping were less likely to purchase bread types considered more nutritious than white bread (OR = 0·75; 95 % CI 0·59, 0·95) and milk types considered more nutritious than full-cream milk (OR = 0·62; 95 % CI 0·47, 0·81). The food insecurity indicators were not associated with the purchasing of fruits, vegetables or non-chain fast food. Householders experiencing financial and physical barriers were more likely to frequently purchase chain fast foods while limited access to a car resulted in a lower likelihood that the nutritious options were purchased for two core food items (bread and milk). Policies and interventions that improve financial access to food and lessen the effect of physical limitations to carrying groceries may reduce the purchasing of fast foods. Further research is required on food sourcing and dietary quality among those with food access restrictions.

The purpose of the present study was to explore food preparation behaviours, attitudes, meal planning and shopping among Mexican-American mothers. Data were collected through four focus groups with mothers of Mexican origin/ancestry who considered themselves to be the primary food preparer. Topics included food preparation behaviours and influencers (culture, family, attitudes, barriers, meal planning and shopping). Data were analysed using a qualitative grounded theory approach. All focus groups were audio recorded, transcribed verbatim and coded for themes. Data were collected in southern California, USA in 2013. Of the sample of twenty-one Mexican-American mothers, thirteen were born outside the USA and the mean household size was five members. Participants reported that food was often prepared using traditional staples and food preparation behaviours were learned from maternal family members. Participants also suggested that health was influenced by foods eaten and how they were prepared. Salient factors influencing food preparation behaviours included culture and tradition, maternal family members' food preparation behaviours, food preparation self-efficacy and attitudes towards healthy eating. Time and busy schedules were cited as barriers. Future interventions should consider utilizing family-based approaches and teaching culturally relevant food preparation skills, especially to youth, while reinforcing more healthful dietary practices.

Research on the local knowledge of food plants used by Karo ethnic in the Semangat Gunung Village, North Sumatra has been done. The aim of this study is to reveal plant species that used by the people of Karo ethnic as food. We used the ethnobotanical approach which included open-ended, semi-structural interview, and exploration method. One eldervillage, 2 traditional healers, and 30 respondents have been selected as sources of information. Descriptive statistics have been used to analyze the gathered data. A number of 109 species which belong to 83 genus and 45 families known to be used as food sources by Karo people. Four families have the highest number of food plant species, which are Solanaceae (8 species), Poaceae (7 species), Fabaceae (6 species), and Zingiberaceae (6 species). All of those families are found in the village, both wild and Cultivated. Solanaceae is used as source of fruits, vegetables, and spices. Poaceae is used as the source of the staple food, alternative food sources, snacks, spices, and traditional foods. Fabaceae is used as source of vegetables and traditional foods. Zingiberaceae is used as source of spices.

Toxicants exposures as novel zoonoses: reflections on sustainable development, food safety and veterinary public health.

Frazzoli, C; Mantovani, A

The modern concept of zoonosis considers any detriment to the health and/or quality of human life resulting from relationships with (other) vertebrate or edible or toxic invertebrate animals. Whereas exposure to toxicants through foods of animal origin (a.o.) is a well-established issue, hereby we discuss it as novel zoonoses, from the standpoints of health implications as well as similarities and differences with classical zoonoses caused by biological agents. Novel toxicant-related zoonoses are linked with new issues in food safety, such as the environment-feed-food chain. In fact, the potential effect of the combined and repeated exposure to dietary toxicants is generally long-term and not readily discernible. Endocrine disrupting chemicals in staple foods of a.o. are discussed as a telling example of a food safety issue summing up critical points covered by the definition of sustainable development, also implicating health risks for generations to come. We suggest some critical points to implement the veterinary public health action in sustainable food safety, such as enhancement of Hazard Analysis and Critical Control Points systems for toxicological risk management. © 2010 Blackwell Verlag GmbH.

Excess consumption of added sugars has been associated with a variety of health problems, but there is little information available characterizing added sugar in the Canadian food supply. This study examined the presence and types of added sugars in the packaged food and beverage products available at a major Canadian grocery retailer. We searched the ingredients lists of over 40 000 packaged food products available for sale in March 2015 for a variety of added sugar terms. Proportions of food products containing added sugar were identified overall and within food product categories. Differences in total sugar content were identified between food products with and without added sugar. Overall, 66% of the packaged food products analyzed contained at least 1 added sugar. The added sugar term "sugar" (and its variations) appeared the most frequently, followed by "dextrose." Added sugar presence and total sugar content varied within many product categories but were consistently higher in expected categories such as "beverages." Mean total sugar content was significantly higher in products with added sugar than in those without, both overall ( p added sugar, similar to recent patterns estimated for the US food supply. The results provide an estimation of the baseline characterization of added sugar in the Canadian food supply, which can be used to assess outcomes of future changes to sugar labelling policies in Canada.

Water and Land Limitations to Future Agricultural Production in the Middle East

2015-12-01

Countries in the Middle East use a large fraction of their scarce water resources to produce cash crops, such as fruit and vegetables, for international markets. At the same time, these countries import large amounts of staple crops, such as cereals, required to meet the nutritional demand of their populations. This makes food security in the Middle East heavily dependent on world market prices for staple crops. Under these preconditions, increasing food demand due to population growth, urban expansion on fertile farmlands, and detrimental effects of a changing climate on the production of agricultural commodities present major challenges to countries in the Middle East that try to improve food security by increasing their self-sufficiency rate of staple crops.We applied the spatio-temporal land-use change model LandSHIFT.JR to simulate how an expansion of urban areas may affect the production of agricultural commodities in Jordan. We furthermore evaluated how climate change and changes in socio-economic conditions may influence crop production. The focus of our analysis was on potential future irrigated and rainfed production (crop yield and area demand) of fruit, vegetables, and cereals. Our simulation results show that the expansion of urban areas and the resulting displacement of agricultural areas does result in a slight decrease in crop yields. This leads to almost no additional irrigation water requirements due to the relocation of agricultural areas, i.e. there is the same amount of "crop per drop". However, taking into account projected changes in socio-economic conditions and climate conditions, a large volume of water would be required for cereal production in order to safeguard current self-sufficiency rates for staple crops. Irrigation water requirements are expected to double until 2025 and to triple until 2050. Irrigated crop yields are projected to decrease by about 25%, whereas there is no decrease in rainfed crop yields to be expected.

Effects of Large-Scale Acquisition on Food Insecurity in Sierra Leone

Full Text Available The recent phenomenon of large-scale acquisition of land for a variety of investment purposes has raised deep concerns over the food security, livelihood and socio-economic development of communities in many regions of the developing world. This study set out to investigate the food security outcomes of land acquisitions in northern Sierra Leone. Using a mixture of quantitative and qualitative research methods, the study measures the severity of food insecurity and hunger, compares the situation of food security before and after the onset of operations of a land investing company, analyzes the food security implications of producing own food versus depending on wage labour for household food needs, and evaluates initiatives put in place by the land investing company to mitigate its food insecurity footprint. Results show an increase in the severity of food insecurity and hunger. Household income from agricultural production has fallen. Employment by the land investing company is limited in terms of the number of people it employs relative to the population of communities in which it operates. Also, wages from employment by the company cannot meet the staple food needs of its employees. The programme that has been put in place by the company to mitigate its food insecurity footprint is failing because of a host of reasons that relate to organization and power relations. In conclusion, rural people are better off producing their own food than depending on the corporate structure of land investment companies. Governments should provide an enabling framework to accommodate this food security need, both in land investment operations that are ongoing and in those that are yet to operate.

Large price increases over a short time period can be indicative of a deteriorating food security situation. Food price indices developed by the United Nations Food and Agriculture Organization (FAO) are used to monitor food price trends at a global level, but largely reflect supply and demand conditions in export markets. However, reporting by the United States Agency for International Development (USAID)'s Famine Early Warning Systems Network (FEWS NET) indicates that staple cereal prices in many markets of the developing world, especially in surplus-producing areas, often have a delayed and variable response to international export market price trends. Here we present new price indices compiled for improved food security monitoring and assessment, and specifically for monitoring conditions of food access across diverse food insecure regions. We found that cereal price indices constructed using market prices within a food insecure region showed significant differences from the international cereals price, and had a variable price dispersion across markets within each marketshed. Using satellite-derived remote sensing information that estimates local production and the FAO Cereals Index as predictors, we were able to forecast movements of the local or national price indices in the remote, arid and semi-arid countries of the 38 countries examined. This work supports the need for improved decision-making about targeted aid and humanitarian relief, by providing earlier early warning of food security crises.

A Systematic Review of Perennial Staple Crops Literature Using Topic Modeling and Bibliometric Analysis

Science.gov (United States)

2016-01-01

Research on perennial staple crops has increased in the past ten years due to their potential to improve ecosystem services in agricultural systems. However, multiple past breeding efforts as well as research on traditional ratoon systems mean there is already a broad body of literature on perennial crops. In this review, we compare the development of research on perennial staple crops, including wheat, rice, rye, sorghum, and pigeon pea. We utilized the advanced search capabilities of Web of Science, Scopus, ScienceDirect, and Agricola to gather a library of 914 articles published from 1930 to the present. We analyzed the metadata in the entire library and in collections of literature on each crop to understand trends in research and publishing. In addition, we applied topic modeling to the article abstracts, a type of text analysis that identifies frequently co-occurring terms and latent topics. We found: 1.) Research on perennials is increasing overall, but individual crops have each seen periods of heightened interest and research activity; 2.) Specialist journals play an important role in supporting early research efforts. Research often begins within communities of specialists or breeders for the individual crop before transitioning to a more general scientific audience; 3.) Existing perennial agricultural systems and their domesticated crop material, such as ratoon rice systems, can provide a useful foundation for breeding efforts, accelerating the development of truly perennial crops and farming systems; 4.) Primary research is lacking for crops that are produced on a smaller scale globally, such as pigeon pea and sorghum, and on the ecosystem service benefits of perennial agricultural systems.

The performance of most bariatric procedures within an Enhanced Recovery After Surgery program has resulted in significant advantages, including a reduction in the length of hospital stay to 2-3 days. However, some postoperative complications may appear after the patient has been discharged. The aim of this study was to investigate the efficacy of various acute-phase parameters determined 24 h after a laparoscopic sleeve gastrectomy for predicting staple line leak in the postoperative course. A prospective study of 208 morbidly obese patients undergoing laparoscopic sleeve gastrectomy as bariatric procedure between 2012 and 2015 was performed. Blood analysis was performed 24 h after surgery. Acute-phase parameters (C-reactive protein, procalcitonin, fibrinogen, and White Blood Cell count) were investigated. Staple line leak appeared in eight patients (3.8%). Using receiver operating characteristic analysis at 24 h postoperatively, a cutoff level of CRP at 9 mg/dL achieved 85% sensitivity and 90% specificity for predicting staple line leak, a cutoff level of procalcitonin at 0.85 ng/mL achieved 70% sensitivity and 90% specificity, and a cutoff level of fibrinogen at 600 mg/dL achieved 80% sensitivity and 87.5% specificity. An elevation of CRP > 9 mg/dL, procalcitonin > 0.85 ng/mL and fibrinogen > 600 mg/dL should alert the surgeon the possibility of occurrence of postoperative staple line leak.

In order to investigate the direct plant contamination pathway of 54 Mn, 57 Co, 85 Sr, 103 Ru and 134 Cs in major food crops for Koreans, rice, soybean and radish plants at different growth stages were sprayed with radioactive solutions in a greenhouse. The interception factor and the translocation factor were quantified as the fraction of the total deposition that is initially retained on the aboveground plant surface and the fraction of the total initial plant activity that is contained in the edible part at harvest, respectively. In rice and radish, interception factors increased as plants grew old to harvest. In soybean, however, rapid defoliation in old plants made interception factors decrease with increasing age during the later part of the growth. There was little difference in the interception factor among radionuclides. Translocation factors decreased in the order of 134 Cs ≥> 57 Co > 54 Mn ≥ 85 Sr > 103 Ru in general and varied with radionuclides by factors of 6-4000, depending on application time and plant species. Translocation factors for rice seeds were the highest when radionuclides were applied at the active seed growth stage and those for soybean seeds were the highest following the application at the early pod-filling stage except for 103 Ru. For radish roots, translocation factors were on the whole the highest following the early- growth-stage application. The obtained data can be used for parameter values in food-chain dose assessment models especially for Koreans and many other Asian people

Surgical technique and perioperative management in rectal cancer surgery have been substantially improved and standardized during the last decades. However, anastomotic leakage following low anterior resection still is a significant problem. Based on animal experimental data of improved healing of compression anastomosis, we hypothesized that a compression anastomotic device might improve healing rates of the highest-risk anastomoses. All low anterior resections for rectal cancer performed or directly supervised by the senior author between January 2004 and June 2012 were analyzed. Only patients with a stapled or compression anastomosis located within 6 cm from the anal verge were included. Until December 2008, circular staplers were employed, while since January 2009, a novel compression anastomotic device was used for rectal reconstruction exclusively. Out of 197 patients operated for rectal cancer, a total of 96 (34 females, 35.4 %) fulfilled inclusion criteria. Fifty-eight (60.4 %) were reconstructed with circular staplers and 38 (39.6 %) using a compression anastomotic device. Significantly, more laparoscopic procedures were recorded in the compression anastomosis group, but distribution of gender, age, body mass index, American Society of Anaesthesiologists score, rate of preoperative radiotherapy, tumor staging, or stoma diversion rate were similar. Anastomotic leakage was observed in seven cases (7/58, 12.1 %) in the stapled and twice (2/38, 5.3 %) in the compression anastomosis group (p = 0.26). In this series, rectal reconstruction following low anterior resection using a novel compression anastomotic device was safe and (at least) equally effective compared to traditional circular staplers concerning leak rate.

The residential neighbourhood fast-food environment has the potential to lead to increased levels of obesity by providing opportunities for residents to consume energy-dense products. This longitudinal study aimed to examine whether change in body mass index (BMI) differed dependent on major chain fast-food outlet availability among women residing in disadvantaged neighbourhoods. Eighty disadvantaged neighbourhoods in Victoria, Australia. Sample of 882 women aged 18-46 years at baseline (wave I: 2007/2008) who remained at the same residential location at all three waves (wave II: 2010/2011; wave III: 2012/2013) of the Resilience for Eating and Activity Despite Inequality study. BMI based on self-reported height and weight at each wave. There was no evidence of an interaction between time and the number of major chain fast-food outlets within 2 (p=0.88), 3 (p=0.66) or 5 km (p=0.24) in the multilevel models of BMI. Furthermore, there was no evidence of an interaction between time and change in availability at any distance and BMI. Change in BMI was not found to differ by residential major chain fast-food outlet availability among Victorian women residing in disadvantaged neighbourhoods. It may be that exposure to fast-food outlets around other locations regularly visited influence change in BMI. Future research needs to consider what environments are the key sources for accessing and consuming fast food and how these relate to BMI and obesity risk. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Finney, P L

Wheat and soybeans are the major agricultural exports of the United States. The U.S. sells more of each crop than any other nation. Soybeans are the main staple in China, but the U.S. sells more soybeans than China grows. For hundreds of millions of other people, wheat is the main staple. And yet, most Americans eat whole grains of neither wheat nor soybeans. In the United States, many nutrients of wheat and soybeans are lost in processing or are fed to animals. A highly significant share of the wheat nutrients are lost from the main foodstream when the germ and bran (with aleurone) portions are separated. Whole soybeans are carefully processed for food by only a handful of Americans.

In many parts of sub-Saharan Africa, subsistence agriculture is characterized by significant fluctuations in yield and production due to variations in moisture availability to staple crops. Widespread drought can lead to crop failures, with associated deterioration in food security. Ground data collection networks are sparse, so methods using geospatial rainfall estimates derived from satellite and gauge observations, where available, have been developed to calculate seasonal crop water balances. Using conventional crop production data for 4 years in Ethiopia (1996-1999), it was found that water-limited and water-unlimited growing regions can be distinguished. Furthermore, maize growing conditions are also indicative of conditions for sorghum. However, another major staple, teff, was found to behave sufficiently differently from maize to warrant studies of its own.

The objective of the study was to assess the change in quality of life (QOL of patients undergoing stapled hemorrhoidopexy (SH using WHO Quality of Life-BREF (WHOQOL-BREF questionnaire. Methods. The study sample comprised patients with symptomatic II, III, and IV degree hemorrhoids, undergoing SH. The patients were asked to complete WHOQOL-BREF questionnaire before and one month following the surgery. Result. There were 20 patients in the study group. The postoperative pain score measured by visual analogue scale at six hours postoperatively was at 24 hours. The items in the WHOQOL-BREF had high-internal consistency or reliability as shown by high Cronbach's alpha coefficient which was 0.82 and 0.90 for pre- and postoperative questionnaires. There was significant improvement in the overall perception of QOL and health, and in physical and psychological domains. There was modest improvement in environmental domain, while no change was noted in social domain. Conclusion. SH improved the quality of life of patients treated for hemorrhoids.

Evaluating the impact of climate policies on regional food availability and accessibility using an Integrated Assessment Model

2015-12-01

Beyond 2015, eradicating hunger will remain a critical part of the global development agenda through the Sustainable Development Goals (SDG). Efforts to limit climate change through both mitigation of greenhouse gas emissions and land use policies may interact with food availability and accessibility in complex and unanticipated ways. Here, we develop projections of regional food accessibility to 2050 under the alternative futures outlined by the Shared Socioeconomic Pathways (SSPs) and under different climate policy targets and structures. We use the Global Change Assessment Model (GCAM), an integrated assessment model (IAM), for our projections. We calculate food access as the weighted average of consumption of five staples and the portion of income spend on those commodities and extend the GCAM calculated universal global producer price to regional consumer prices drawing on historical relationships of these prices. Along the SSPs, food access depends largely on expectations of increases in population and economic status. Under a more optimistic scenario, the pressures on food access from increasing demand and rising prices can be counterbalanced by faster economic development. Stringent climate policies that increase commodity prices, however, may hinder vulnerable regions, namely Sub-Saharan Africa, from achieving greater food accessibility.

To identify major dietary patterns and their association with socio-economic status (SES) and food insecurity in two major ethnic groups living in Urmia, north-west Iran. A cross-sectional study. All four geographical zones of Urmia city. Participants (n 723; 427 women and 296 men), aged 20-64 years, from two ethnic groups (445 Azeri Turks and 278 Kurds). Three major dietary patterns were extracted: 'Traditional High SES' (THS), 'Traditional Low SES' (TLS) and 'Transitional'. After adjusting for confounders, the THS pattern was positively associated with education level and negatively associated with moderate or severe food insecurity in Azeri Turks; whereas, among Kurds, it was more common in women and positively associated with age. The TLS pattern was more common among men and negatively associated with educational level and all levels of food insecurity in Azeris; while, among Kurds, it was more common among men, positively associated with being married and negatively associated with household income/capita. The 'Transitional' pattern was positively associated with being employed and negatively associated with age and all levels of food insecurity in Azeris; while, among Kurds, it was more common among men and negatively associated with age, being married and physical activity level. Findings suggest that household SES and food insecurity are associated with detrimental dietary patterns and that this effect may be stronger than cultural and ethnic background. These patterns differ by age and gender. Therefore, such characteristics should be considered in planning and formulating diet-related policies and programmes.

This study was conducted to help better understand the current sodium intake of Korean children and to establish children's good eating habits through investigation of the sodium content of ready-to-eat foods collected from nine major amusement parks in Korea. The sodium content of a total of 322 products was analysed by using ICP and then the potential risk based on the recommended daily intake of sodium as described in the Korean dietary reference intakes was determined. The results showed that sodium content was the lowest in muffins (245 mg/100 g) and the highest in seasoned dried filefish (1825 mg/100 g). The average amounts of sodium per serving of seasoned dried filefish, tteokbokki and fish paste were 1150, 1248 and 1097 mg, respectively. The values were above 50% of the daily intake of sodium recommended by the Korean dietary reference intake. The ready-to-eat foods were also classified into high, medium and low sodium content on the basis of standards recommended by the Korean Food and Drug Administration. Most snacks were classified as high sodium foods because they exceeded "300 mg (84.5% of the total daily allowance)". Furthermore, the meal substitution foods such as kimbab, tteokbokki, mandus, sandwiches and hamburgers exceeded "600 mg (90.3% of the total daily allowance)" and were also classified as high sodium foods. In addition, ready-to-eat foods in amusement parks are similar to foods eaten on streets and foods around school zones, which contain high sodium content; thus, the intake frequency might be high, which would induce high risk to children health. Koreans already consume a high amount of sodium daily via their usual diets. So, the sodium content in snacks and substitution foods needs to be reduced. Consequently, this study noted that parents and guardians should carefully consider their children's consumption of ready-to-eat foods from Korean amusement parks.

As the credential for nutrition counselor with professional skills and knowledge for invalids, who also provides the nutrition education for local residence at the administrative organization, the qualification system of registered dietitian has been established in Japan. Additionally, in accordance with the legislation of Basic Act on Food Education and the revision of School Education Law, the Diet and Nutrition Teacher System has established in 2005. Therefore, registered dietitian has been approved to teach at the elementary school or junior high school as a teacher. Since registered dietitian is the educator of the “diet and nutrition,” it is important to provide proper knowledge of food irradiation at the training facility for registered dietitian. This report describes the instruction of food irradiation at the education curriculum of the registered dietitian training course. In addition, questionnaire survey result on the knowledge of food irradiation gathered from newly-enrolled students in the registered dietitian training course will also be reported. (author)

Plant biotechnology can make important contributions to food security and nutritional improvement. For example, the development of 'Golden Rice' by Professor Ingo Potrykus was a milestone in the application of gene technology to deliver both increased nutritional qualities and health improvement to wide sections of the human population. Mineral nutrient and protein deficiency as well as food security remain the most important challenges for developing countries. Current projects are addressing these issues in two major staple crops, cassava (Manihot esculenta Crantz) and rice. The tropical root crop cassava is a major source of food for approximately 600 million of the population worldwide. In sub-Saharan Africa >200 million of the population rely on cassava as their major source of dietary energy. The nutritional quality of the cassava root is not sufficient to meet all dietary needs. Rice is the staple food for half the world population, providing approximately 20% of the per capita energy and 13% of the protein for human consumption worldwide. In many developing countries the dietary contributions of rice are substantially greater (29.3% dietary energy and 29.1% dietary protein). The current six most popular 'mega' rice varieties (in terms of popularity and acreage), including Chinese hybrid rice, have an incomplete amino acid profile and contain limited amounts of essential micronutrients. Rice lines with improved Fe contents have been developed using genes that have functions in Fe absorption, translocation and accumulation in the plant, as well as improved Fe bioavailability in the human intestine. Current developments in biotechnology-assisted plant improvement are reviewed and the potential of the technology in addressing human nutrition and health are discussed.

Food preparation in colonial America. A Bicentennial study.

Science.gov (United States)

Bennion, M

1976-07-01

Both regional and national influences have pervaded America's culinary arts from colonial times until the present. In the South, for instance, indigenous foods, such as sweet potatoes--as well as an abundance of fruits and fowl--were commonly served. In the North, maple sirup was a New England product, as was codfish. Throughout the colonies, corn was easily grown and became a staple. Immigrants from the Old World brought their recipes to meld or adapt to conditions they met here. Recounted also is the unfolding of an American cuisine, especially in the southern colonies as it evolved from European food preparation practices. Cooking was done in great fireplaces, with equipment designed to fit. Meat was generally boiled or stewed in pots hung in the fireplace, although it might be slow-roasted on a hand-turned spit. Hot breads, the hallmark of southern cooking, date from colonial days. In the Noth, the Dutch farmer's wife developed real skill in using flour from home-grown wheat and rye, creating pancakes, waffles, doughnuts, crullers, and so on. After the first hard winter, food in New England became more plentiful. Boston brown bread was made from corn, wheat, or rye and probably sweetened with maple sirup. Imports of coffee, tea, and spices from the Orient and fruit from the tropics were later added to the cuisine. Colonial Americans understood well the art of food preparation and appreciated the taste of well prepared, well seasoned dishes.

In South Africa, households living in informal urban settlements, in rural areas, and on commercial farms experience various levels of dietary variety, food intake, and household hunger. Low incomes, poor food production and availability, and low spending power characterize these households. Households employ various food-coping strategies to alleviate food stress or poor food availability. To apply an existing food-coping strategy (FCS) index to assess household hunger and its usefulness in identifying the level of food stress and the patterns of food coping in farm-worker households. A cross-sectional survey was conducted. Data were gathered from women (18 to 57 years of age) responsible for food provision in a small farm-worker community in Fouriesburg, South Africa. A structured food-coping questionnaire and a standardized FCS index were used to gather data. The two most common FCS used were relying on cheaper food (chicken feet, diluted soya-mince soup) or less preferred food (meat bones) and employing food-seeking strategies (gathering wild foods), followed by consumption of seed stock (maize) and reduced portion sizes (protein foods and side dishes), resulting in starch-based diets of poor variety. Seasonal strategies varied according to the level of food stress experienced. Patterns of food coping were identified. Negative FCS (limiting food choices, only consuming starchy staples) may cause poor health status. The FCS index was effectively used to assess farm-worker household food-coping behavior (early, clear signals of the level of food distress). These results could be used to allocate appropriate food aid (type of food) and to design nutrition education programs focused on positive FCS (food gathering or bartering) in a particular community to prevent suboptimal nutritional status.

Se exhibited a relatively small range of adequate ingestion level for health. An accurate investigation of Se consumption in Korean population has been rare because the database of food containing selenium is rather small. The table of Se content in food is a basic tool for calculating selenium intake. Since diet is the main source of Se intake, the Se content in various foods and personal dietary practices would be primarily determined to evaluate the nutritional status of Se for a population. To evaluate the Se intake levels of a population, a Se food database should be generated based on data produced by high-precision analytical techniques. In addition, this database should contain the Se contents of foods that are regularly consumed by the studied population. Plant foods contain lower Se levels when compared to animal products. However, grains, potatoes, starches, and legumes have been the main sources of carbohydrates and proteins in traditional Korean diet. Since grains such as rice are a staple food and remain the most consumed foods in Korea, their contribution to dietary Se intake might be considerable. However, no reports on the selenium content from plant foods have been compiled for the Korean population. The goal of this study was to measure the Se content in common consumed plant foods such as grain, potatoes, legumes and their products. The legume rich in protein contained relatively high amount of Se when compared to other plant food type. The raw wheat and wheat product which have been imported from abroad showed higher amount of Se than rice mostly produced in Korea. The acquired Se value is useful to assess the Se intake of Korean adults from plant foods.

Sweet has always been a very important basic taste for mankind, although sweetness is always related to either weight gain or teeth decay. Sweeteners entered the food industry back in the 1800's and are now staple in foodstuffs. Despite their long relationship with food, sweeteners have been in the spotlights for many reasons. Since being the perfect choice for diabetics, to the dangers concerning toxicity, cancer and other health issues associated with their consumption, sweeteners have come a long way. The conflicting results for the same sweeteners and the divergent regulations are fuel for a wide debate on the impact of sweeteners in the industry, health and lifestyle of mankind. In this review, the history, main concerns, benefits, disadvantages, classification and future trends are revisited for nutritive, intense and natural food additives, while future perspectives are hypothesized.

Peschel, Anne O; Grebitus, Carola; Steiner, Bodo; Veeman, Michele

2016-11-01

This paper examines consumers' knowledge and lifestyle profiles and preferences regarding two environmentally labeled food staples, potatoes and ground beef. Data from online choice experiments conducted in Canada and Germany are analyzed through latent class choice modeling to identify the influence of consumer knowledge (subjective and objective knowledge as well as usage experience) on environmentally sustainable choices. We find that irrespective of product or country under investigation, high subjective and objective knowledge levels drive environmentally sustainable food choices. Subjective knowledge was found to be more important in this context. Usage experience had relatively little impact on environmentally sustainable choices. Our results suggest that about 20% of consumers in both countries are ready to adopt footprint labels in their food choices. Another 10-20% could be targeted by enhancing subjective knowledge, for example through targeted marketing campaigns. Copyright © 2016 Elsevier Ltd. All rights reserved.

Metallic skin closure staples and vessel ligation clips should be tested at 3-Tesla to characterize MRI issues in order to ensure patient safety. Therefore, metallic surgical implants were assessed at 3-Tesla for magnetic field interactions, MRI-related heating, and artifacts. A skin closure staple (Visistat Skin Stapler, staple, Polytetrafluoroethylene, PTFE, coated 316L/316LVM stainless steel; Teleflex Medical, Durham, NC) and a vessel ligation clip (Hemoclip Traditional, stainless steel; Teleflex Medical, Durham, NC) that represented the largest metallic sizes made from materials with the highest magnetic susceptibilities (i.e., based on material information) among 61 other surgical implants (52 metallic implants, 9 nonmetallic implants) underwent evaluation for magnetic field interactions, MRI-related heating, and artifacts using standardized techniques. MRI-related heating was assessed by placing each implant in a gelled-saline-filled phantom with MRI performed using a transmit/receive RF body coil at an MR system reported, whole body averaged SAR of 2.9-W/kg for 15-min. Artifacts were characterized using T1-weighted, SE and GRE pulse sequences. Each surgical implant showed minor magnetic field interactions (20- and 27-degrees, which is acceptable from a safety consideration). Heating was not substantial (highest temperature change, ≤ 1.6°C). Artifacts may create issues if the area of interest is in the same area or close to the respective surgical implant. The results demonstrated that it would be acceptable for patients with these metallic surgical implants to undergo MRI at 3-Tesla or less. Because of the materials and dimensions of the surgical implants that underwent testing, these findings pertain to 61 additional similar implants.

For investigating the contamination pathways of major radionuclides in staple food crops, greenhouse experiments in which rice, Chines cabbage and radish were exposed to mixed γ radionuclides of Mn-54, Co-60, Sr-85, Ru-103 and Cs-134 and H-3 at different growth stages, were conducted to generate data on parameters concerning the direct contamination of those crops. Experiments of the exposure to iodine gas were also performed for rice and radish at their various growth stages to obtain contamination parameters of elemental iodine. Based on data obtained from the experiments mentioned above, a database program was constructed to make it possible to search parameter values for different radionuclides, crops and deposition times in an easy way have an graphic output of the variation in the contamination parameter with deposition times. Paddy-field soils were collected from 5 or 6 places around Kori and Youngkwang NPPs and physicochemical properties and background radioactivity levels of the soils were investigated. Soil-to-rice transfer factors of Sr-90 and Cs-137 in the collected soils were determined for different RI application times. For Kori soils, transfer factors were also measured in the second year to investigate the yearly variation. In addition, the conceptual design of an automatized experimental greenhouse was performed to be used as a basic material for a detailed design for the construction in the future

Water Footprint and Impact of Water Consumption for Food, Feed, Fuel Crops Production in Thailand

Directory of Open Access Journals (Sweden)

Shabbir H. Gheewala

2014-06-01

Full Text Available The proliferation of food, feed and biofuels demands promises to increase pressure on water competition and stress, particularly for Thailand, which has a large agricultural base. This study assesses the water footprint of ten staple crops grown in different regions across the country and evaluates the impact of crop water use in different regions/watersheds by the water stress index and the indication of water deprivation potential. The ten crops include major rice, second rice, maize, soybean, mungbean, peanut, cassava, sugarcane, pineapple and oil palm. The water stress index of the 25 major watersheds in Thailand has been evaluated. The results show that there are high variations of crop water requirements grown in different regions due to many factors. However, based on the current cropping systems, the Northeastern region has the highest water requirement for both green water (or rain water and blue water (or irrigation water. Rice (paddy farming requires the highest amount of irrigation water, i.e., around 10,489 million m3/year followed by the maize, sugarcane, oil palm and cassava. Major rice cultivation induces the highest water deprivation, i.e., 1862 million m3H2Oeq/year; followed by sugarcane, second rice and cassava. The watersheds that have high risk on water competition due to increase in production of the ten crops considered are the Mun, Chi and Chao Phraya watersheds. The main contribution is from the second rice cultivation. Recommendations have been proposed for sustainable crops production in the future.

Analysis of U.S. Food and Drug Administration food allergen recalls after implementation of the food allergen labeling and consumer protection act.

Gendel, Steven M; Zhu, Jianmei

2013-11-01

To avoid potentially life-threatening reactions, food allergic consumers rely on information on food labels to help them avoid exposure to a food or ingredient that could trigger a reaction. To help consumers in the United States obtain the information that they need, the Food Allergen Labeling and Consumer Protection Act of 2004 defined a major food allergen as being one of eight foods or food groups and any ingredient that contains protein from one of these foods or food groups. A food that contains an undeclared major food allergen is misbranded under the U.S. Food, Drug, and Cosmetic Act and is subject to recall. Food allergen labeling problems are the most common cause of recalls for U.S. Food and Drug Administration (FDA)-regulated food products. To help understand why food allergen recalls continue to occur at a high rate, information on each food allergen recall that occurred in fiscal years 2007 through 2012 was obtained from the FDA recall database. This information was analyzed to identify the food, allergen, root cause, and mode of discovery for each food allergen recall. Bakery products were the most frequently recalled food type, and milk was the most frequently undeclared major food allergen. Use of the wrong package or label was the most frequent problem leading to food allergen recalls. These data are the first reported that indicate the importance of label and package controls as public health measures.

The monitoring of staple and high-value crops is important for maintaining food security. The recent launch of numerous remote sensing satellites has created the ability to monitor vast amounts of crop lands, continuously and in a timely manner. This monitoring provides users with a wealth of information on various crop types over different regions of the world. However, a challenge still remains on how to best quantify and interpret the crop and surface characteristics that are measured by visible, near-infrared, and active and passive microwave radar. Currently, two NASA funded projects are examining the ability to monitor different types of crops in California with different remote sensing platforms. The goal of both projects is to develop a cost-effective monitoring tool for use by vineyard and crop managers. The first project is designed to examine the capability to monitor vineyard water management and soil moisture in Sonoma County using Soil Moisture Active Passive (SMAP), Sentinel-1A and -2, and Landsat-8. The combined mission products create thorough and robust measurements of surface and vineyard characteristics that can potentially improve the ability to monitor vineyard health. Incorporating the Michigan Microwave Canopy Scattering (MIMICS), a radiative transfer model, enables us to better understand surface and vineyard features that influence radar measurements from Sentinel-1A. The second project is a blended approach to analyze corn, rice, and wheat growth using Sentinel-1A products with Decision Support System for Agrotechnology Transfer (DSSAT) and MIMICS models. This project aims to characterize the crop structures that influence Sentinel-1A radar measurements. Preliminary results have revealed the corn, rice, and wheat structures that influence radar measurements during a growing season. The potential of this monitoring tool can be used for maintaining food security. This includes supporting sustainable irrigation practices, identifying crop

Crop growth and productivity has largely been vulnerable to various abiotic and biotic stresses that are only set to be compounded due to global climate change. Therefore developing improved varieties and designing newer approaches for crop improvement against stress tolerance have become a priority now-a-days. However, most of the crop improvement strategies are directed toward staple cereals such as rice, wheat, maize etc., whereas attention on minor cereals such as finger millet [ Eleusine coracana (L.) Gaertn.] lags far behind. It is an important staple in several semi-arid and tropical regions of the world with excellent nutraceutical properties as well as ensuring food security in these areas even during harsh environment. This review highlights the importance of finger millet as a model nutraceutical crop. Progress and prospects in genetic manipulation for the development of abiotic and biotic stress tolerant varieties is also discussed. Although limited studies have been conducted for genetic improvement of finger millets, its nutritional significance in providing minerals, calories and protein makes it an ideal model for nutrition-agriculture research. Therefore, improved genetic manipulation of finger millets for resistance to both abiotic and biotic stresses, as well as for enhancing nutrient content will be very effective in millet improvement. Key message: Apart from the excellent nutraceutical value of finger millet, its ability to tolerate various abiotic stresses and resist pathogens make it an excellent model for exploring vast genetic and genomic potential of this crop, which provide us a wide choice for developing strategies for making climate resilient staple crops.

Use and Preference of Advice on Small Children's Food: Differences Between Parents From Ethnic Minority, Ethnic Majority, and Mixed Households.

The authors analyzed the influence of acculturation on parental attitudes to, and use of, different sources of health advice about young children's food in Denmark. Using combined ethnic position of the children's parents as a proxy for household acculturation, the authors conducted a postal survey of 2,511 households with young children (6 months to 3.5 years) occupying ethnic minority, ethnic majority, or ethnic mixed position. The analysis showed that the use of advice differed in the 3 groups. Households with ethnic minority status were more likely to use the child's grandparents, general practitioners, and hospital staff as information sources, while households with ethnic majority status were more likely to use mothers' peer groups and written material. In all types of household municipal public health nurses were relied on as a source of advice on young children's food, but households with ethnic minority status were more likely to find the advice obtained in this way incompatible with their family eating habits. Although existing dietary health communication strategies delivered by public health nurses appear to work well in all household types, parents from minority households seem to experience dilemmas. These may be related to their cultural and generational status at the time of receiving the advice. Adjustments to current communication strategies on young children's food are suggested.

Intakes of various nutrients by working women in Manila, the Philippines, was surveyed by the total food duplicate method, with foci to elucidate relative weight of three meals and snack in addition to quantitative evaluation of nutrient intakes. In practice, 45 women (average age; 37.2 years) volunteered, who were all nonsmokers and nonhabitual drinkers, and mostly married. In parallel, hematology, serum biochemistry, anthropometry and clinical examinations were conducted. On average, the women took 1787 kcal energy, 57 g protein, and 54 g lipid daily. Comparison with the Recommended Dietary Allowances (RDA) for Filipinos showed that intakes of energy and major nutrients were adequate, whereas that of minerals (e.g., 15 mg Fe/day vs. 26 mg Fe/day as RDA) and vitamins (e.g., 0.65 mg vitamin B1/day vs. 1 mg/day as RDA) were generally insufficient. Prevalence of anemia was however rather low with an average hemoglobin concentration of 12.9 g/100 ml blood. Rice was the staple source of energy for daily life, and beef rather than fish and shellfish was the leading source of protein. Lunch was the richest meal of a day (with the largest intake of energy, protein and lipid), and snacks rather than dinner appeared to be next substantial.

The concentration of some radiologically and nutritionally important trace elements: Th, Cs, Sr, I, Co, Fe, Zn, Ca and K were determined in major food components such as cereals, pulses, vegetables, fruits, milk etc. The trace elements in food samples were determined using neutron activation analysis technique which involves instrumental and radiochemical neutron activation analysis. Whereas, the trace elements Th, Cs, K and Sr, are important in radiation protection; Fe and Zn are of importance in nutrition studies and Ca and I have dual importance, both in nutrition and radiation protection. The results of analysis show that among the food materials, higher concentrations of Th, Cs, Sr, K, Fe, Zn and Co were found in cereals and pulses. In case of Ca, the milk appears to be the main contributor towards its dietary intake. The estimated concentrations of the trace elements in food components can be employed in determining the daily dietary intake of these elements which in turn can be used for their biokinetic studies.

Root uptake and underground migration of Mn-54, Co-60, Sr-85 and Cs-137 deposited during growing seasons of Korean staple crops such as rice, soybean, potato, Chinese cabbage, radish, red pepper and cucumber were investigated through radio-tracer experiments in greenhouse. H-3 experiments for rice and Chinese cabbage and iodine experiment for Chinese cabbage were also carried out. The effect of KCl and lime application on root uptake and migration of Mn-54, Co-60, Sr-85 and Cs-137 were studied. Long-term (2{approx}5 years depending on crops) behaviors of these radionuclides in soil-plant system were also investigated. Cs-137 concentrations in farm-land soils and crop plants collected in 33 regions of Korea were measured. Soil-to-plant transfer factors of Cs-137 in outdoor fields were compared with those from greenhouse experiments. An improved method of calculating root-uptake concentration of the radionuclide in crop plant was introduced to KFOOD, a food-chain computer code for normal operation. The direction of improving ECOREA, a food-chain computer code for accidental release, was discussed through comparing model calculation of Sr-90 and Cs-137 root-uptake concentrations with present experimental results. Annual food consumption rates and crop yields were updated. (author). 87 refs., 68 tabs., 58 figs.

Aim of the study: Indigenous woody species play an important role as a complement on the diet of rural populations in Niger, especially in periods of food scarcity. However, these species are nowadays overexploited and management programmes are necessary to conserve them. In order to design a conservation programme for edible woody species, this paper presents a sociological analysis about the use of edible woody species and their products during shortage periods in Niger. Area of study: Four villages in two distinct agro-ecological regions were selected to conduct structured enquiries based on focus group discussions and surveys with key informants. Material and Methods: Perceptions of the conservation status of these species were identified; as well the factors affecting food values, perceptions, management and collection practices. Main results: Results show that B. senegalensis was a staple food in the driest areas, and M. crassifolia was used for fodder and human consumption in the most critical situations. The local communities related the drivers of species conservation status specific to the agro-ecological regions, and gender and ethnic differences were also identified. Research highlights: Understanding these factors constitutes a first step towards adaptive management strategies for the conservation of woody food species in rural communities of Niger. (Author)

Recently, the Codex Alimentarius Commission established a maximum limit of 200 µg kg–1 for inorganic arsenic (iAs in rice. Because the maximum content of As in water has been reduced to 10 µg L–1, intoxication through rice and rice-based products can be considered an important source of As poisoning. The chronic effects of this iAs exposure can be lung and bladder cancer, skin lesions, or other noncarcinogenic diseases. There is clear evidence of high levels of iAs in rice and rice-based products. Different solutions for the reduction of As intake are proposed at different levels: 1 during the plant-growing process through agronomic practices, 2 pretreatment of rice before its use in the food industry, 3 optimization of the conditions of unit operations during processing, and 4 by cooking.Keywords: arsenic speciation, food safety, dietary exposure, Oryza sativa

Ileal pouch anal anastomosis (IPAA) may alter sexuality and fertility in women. The laparoscopic approach seems to reduce infertility rates in women after IPAA. However, the impact of hand sewn versus stapled IPAA on sexuality and fertility has never been assessed in patients with ulcerative colitis (UC). The objective of this study was to analyze the impact of the IPAA technique on sexuality and fertility in UC. All UC patients who underwent an IPAA between May 1996 and April 2011 were included. The patients answered mailed questionnaires including sexuality validated questionnaires and fertility questionnaires. The risk factors of sexual dysfunction were explored. A total of 135 patients were included. Eighty-eight patients (65%) answered the questionnaires. Their mean age and follow-up were 37.2 ± 13.4 y and 109.7 ± 57.5 mo. The rates of female and male sexual dysfunction were 50% and 29%, respectively. Intestinal transit disorders were identified as risk factors in both men and women and anastomotic stricture in women sexual dysfunction, in univariate analyses. The IPAA technique did not impact sexual function in women but there was a trend for less erectile dysfunction after hand sewn IPAA (16.7% versus 44.4%). The fertility rate was 47% in women and 75% in men, with a trend for a better fertility in women after hand sewn IPAA (P = 0.07). In this preliminary study, the hand sewn or stapled IPAA technique did not impact the sexuality or fertility outcomes of UC patients, but there was a trend for better female fertility and male erectile function after hand sewn IPAA. Intestinal transit disorders contributed to male and female sexual dysfunction after IPAA. Copyright © 2016 Elsevier Inc. All rights reserved.

Crop growth and productivity has largely been vulnerable to various abiotic and biotic stresses that are only set to be compounded due to global climate change. Therefore developing improved varieties and designing newer approaches for crop improvement against stress tolerance have become a priority now-a-days. However, most of the crop improvement strategies are directed toward staple cereals such as rice, wheat, maize etc., whereas attention on minor cereals such as finger millet [Eleusine coracana (L.) Gaertn.] lags far behind. It is an important staple in several semi-arid and tropical regions of the world with excellent nutraceutical properties as well as ensuring food security in these areas even during harsh environment. This review highlights the importance of finger millet as a model nutraceutical crop. Progress and prospects in genetic manipulation for the development of abiotic and biotic stress tolerant varieties is also discussed. Although limited studies have been conducted for genetic improvement of finger millets, its nutritional significance in providing minerals, calories and protein makes it an ideal model for nutrition-agriculture research. Therefore, improved genetic manipulation of finger millets for resistance to both abiotic and biotic stresses, as well as for enhancing nutrient content will be very effective in millet improvement. Key message: Apart from the excellent nutraceutical value of finger millet, its ability to tolerate various abiotic stresses and resist pathogens make it an excellent model for exploring vast genetic and genomic potential of this crop, which provide us a wide choice for developing strategies for making climate resilient staple crops.

A high incidence of anastomotic leakage (37.5%) is reported after low anterior rectal resection (LAR) and circular double-stapled anastomosis without protective ileostoma. Since the pathomechanism of anastomosis leakage is still unclear, a suitable animal model would be most desirable. The objective was to assess the incidence of clinically apparent and inapparent leakage after LAR in pigs (n = 20). Endpoints were radiological, clinical, macroscopic, and histologic proof of anastomotic leakage on the 9th postoperative day. Integrity of anastomosis was assessed by double-contrast barium examination on 9th postoperative day. Animals were sacrificed and anastomoses were resected for histopathological investigation. In case of earlier clinical apparent anastomotic leakage, radiologic double-contrast barium was performed immediately. LAR with a circular double-stapled anastomosis without protective ileostoma was performed in 20 pigs (m:f = 8:12). Length of resection was 10-20 cm, anastomosis was performed 7 cm ab ano. Five animals (25%) developed clinical apparent anastomotic leakage (no appetite, fever, inactivity, tachypnea, discomfort, pain) between the 6th (n = 1) and 9th (n = 4) postoperative day, proven by double-contrast barium radiographs. Additionally in 1 animal clinical inapparent anastomotic insufficiency was observed radiologically. Total rate of leakage was 30% (n = 6). These results were confirmed by leucocytosis, low potassium levels, in two cases high ALT and AST and local peritonitis in all cases. Including one additional case of clinical inapparent leakage, total rate of anastomotic leakage was 30% (6/20). Thus we managed to establish a new experimental model of anastomotic leakage after low rectal resection comparable to the human situation.

Cysteine-rich peptides (CRPs) of 2-6 kDa are generally thermally and proteolytically stable because of their multiple cross-bracing disulfide bonds. Here, we report the discovery and characterization of two novel cystine-stapled CRPs, designated lybatide 1 and 2 (lyba1 and lyba2), from the cortex of Lycium barbarum root. Lybatides, 32 to 33 amino acids in length, are hyperstable and display a novel disulfide connectivity with a cysteine motif of C-C-C-C-CC-CC which contains two pairs of adjacent cysteines (-CC-CC). X-ray structure analysis revealed the presence of a single cystine-stabilized (α + π)-helix in lyba2, a rare feature of CRPs. Together, our results suggest that lybatides, one of the smallest four-disulfide-constrained plant CRPs, is a new family of CRPs. Additionally, this study provides new insights into the molecular diversity of plant cysteine-rich peptides and the unusual lybatide scaffold could be developed as a useful template for peptide engineering and therapeutic development.

Background Lack of access to healthy foods may explain why residents of low-income neighborhoods and African Americans in the U.S. have high rates of obesity. The findings on where people shop and how that may influence health are mixed. However, multiple policy initiatives are underway to increase access in communities that currently lack healthy options. Few studies have simultaneously measured obesity, distance, and prices of the store used for primary food shopping. Purpose To examine the relationship among distance to store, food prices, and obesity. Methods The Pittsburgh Hill/Homewood Research on Eating, Shopping, and Health study conducted baseline interviews with 1,372 households between May and December 2011 in two low-income, majority African American neighborhoods without a supermarket. Audits of 16 stores where participants reported doing their major food shopping were conducted. Data were analyzed between February 2012 and February 2013. Results Distance to store and prices were positively associated with obesity (pfood prices were jointly modeled, only prices remained significant (pjunk foods relative to healthy foods. Conclusions Placing supermarkets in food deserts to improve access may not be as important as simultaneously offering better prices for healthy foods relative to junk foods, actively marketing healthy foods, and enabling consumers to resist the influence of junk food marketing.

To elucidate gender differences in dietary intake among adults in lowland Nepalese communities. For 122 male and 195 female subjects aged 20 years and over from 94 randomly selected households, interviews using a 19-item food frequency questionnaire were conducted. To determine the portion sizes of these foods, the samples consumed by 56 subjects in a full 1-day period were weighed. Energy expenditure was estimated by time spent on daily activities. Gender differences in per-day energy and protein intakes were related to sex differences in body size and energy expenditure. Apparent gender differences in the crude intakes disappeared when they were expressed by nutrient density (mg or microg/MJ) since micronutrient intakes were significantly correlated with energy intake. However, males' iron intake was larger even after adjustment for energy intake, attributing to their larger portion sizes of commonly consumed staple foods and higher frequencies of consuming luxury foods (fish and tea). The intrahousehold unequal distribution of food incurs risk of iron deficiency among female subjects. This study was financially supported by the Ajinomoto Foundation for Dietary Culture and the Alliance for Global Sustainability Program.

Retailer branding of consumer sales promotions. A major development in food marketing?

Science.gov (United States)

Hamlin, Robert P; Lindsay, Sophie; Insch, Andrea

2012-02-01

This article examines retailer branding of consumer price promotions. It discusses the mechanics of price promotions, consumers' reactions to them and the benefits that accrue to those that use them. It describes how large food retailers can now deploy branded price promotion systems that are fundamentally different to 'traditional' price promotions in both their mechanics and their effects on consumer decision processes. The article describes a field experiment that compared the performance of a food retailer's branded price promotion system with that of a generic (manufacturer) price promotion. The research involved three experiments that covered two food categories (sliced bread and margarine) and two levels of discount (10% and 20%). The results indicate that food retailers are able to attach powerful brands to their price promotion systems, and these brand heuristics can significantly increase consumer purchase intent relative to an equivalent generic/manufacturer promotion. This incremental heuristic effect was stable in both categories and for both levels of price discount studied. These results are consistent with the predictions of alternative, non-cognitive and heuristic based models of food consumer choice that have been published recently in 'Appetite'.

Poor preservation of plant macroremains in the acid soils of southern subtropical China has hampered understanding of prehistoric diets in the region and of the spread of domesticated rice southwards from the Yangtze River region. According to records in ancient books and archaeological discoveries from historical sites, it is presumed that roots and tubers were the staple plant foods in this region before rice agriculture was widely practiced. But no direct evidences provided to test the hypothesis. Here we present evidence from starch and phytolith analyses of samples obtained during systematic excavations at the site of Xincun on the southern coast of China, demonstrating that during 3,350–2,470 aBC humans exploited sago palms, bananas, freshwater roots and tubers, fern roots, acorns, Job's-tears as well as wild rice. A dominance of starches and phytoliths from palms suggest that the sago-type palms were an important plant food prior to the rice in south subtropical China. We also believe that because of their reliance on a wide range of starch-rich plant foods, the transition towards labour intensive rice agriculture was a slow process. PMID:23667584

A survey was conducted on Malaysian food industries to determine the interest and potential applications of food irradiation as an alternative or to complement existing food preservation treatments. A total of 37 food processors representing 5 subsectors of the food industry participated in the survey. Information collected showed that majority of respondents were aware of food irradiation but the level of knowledge was low. Half of respondents perceived food irradiation as safe and 23% will consider using it for commercial purposes. Main concerns of the food processors were safety of the process, safety of irradiated food, efficacy of the process and consumer acceptance. Food irradiation applications considered to have the most potential for use by the food industry, were those which would improve the hygienic quality of food products. Despite the limited knowledge, respondents strongly supported the need to promote food irradiation technology in Malaysia. In view of this finding. various promotional activities have been continuously carried out to increase public awareness and understanding of the technology so as to facilitate acceptance of food irradiation in Malaysia.

Many, if not most, of all important zoonoses relate in some way to animals in the food production chain. Therefore food becomes an important vehicle for many zoonotic pathogens. One of the major issues in food safety over the latest decades has been the lack of cross-sectoral collaboration across...... the food production chain. Major food safety events have been significantly affected by the lack of collaboration between the animal health, the food control, and the human health sector. One Health formulates clearly both the need for, and the benefit of cross-sectoral collaboration. Here we will focus...... on the human health risk related to zoonotic microorganisms present both in food animals and food derived from these animals, and typically transmitted to humans through food. Some diseases have global epidemic- or pandemic-potential, resulting in dramatic action from international organizations and national...

There is a growing interest by both consumers and industry for the development of food products with 'functional' properties, or health benefits. These products may take the form of dietary supplements or of foods. The health benefits are given by particular ingredients, and in many cases these are derived from botanicals. The variety of plants providing these functions is large, ranging from staple food sources such as cereals, fruits and vegetables, to herbals as used in traditional medicine. The food or ingredient conferring health properties may consist of the plants themselves, extracts thereof, or more purified components. The scientific literature is abundant with articles not only on the beneficial properties, but also on possible adverse health effects of plants and their components. The present report discusses the data required to determine the safe use of these types of ingredients, and provides advice on the development of risk assessment strategies consistent with due diligence under existing food regulations. Product specifications, composition and characterisation of standardised and authentic materials, documented history of use and comparison to existing products (taking into account the effect of industrial processing), description of the intended use and consequent exposure are highlighted as key background information on which to base a risk evaluation. The extent of experimental investigation required, such as in vitro, animal, and/or human studies, depends on the adequacy of this information. A decision tree is presented as an aid to determine the extent of data requirements based on product comparison. The ultimate safety in use depends on the establishment of an adequate safety margin between expected exposure and identified potential hazards. Health hazards may arise from inherent toxicities or contaminants of the plant materials, including the mechanism of the intended beneficial effect. A lower safety margin may therefore be expected

Study of the impact of food irradiation on preventing losses: Experience in Africa. Proceedings of a final research co-ordination meeting

International Nuclear Information System (INIS)

2002-05-01

There have been positive developments on food irradiation in different regions of the world, especially in the United States of America and several Asian and Latin American countries. In some countries in Africa, this technology has been studied in the past few decades with encouraging results. To assist these countries in conducting pilot scale research and development on irradiation of specific commodities of interest to them including market testing and feasibility to establish commercial irradiators for multi-purpose application, a Coordinated Research Project (CRP) on Impact of Irradiation to Prevent Food Losses in Africa was carried out between 1995 and 1999. This CRP demonstrated that food irradiation has a potential to reduce losses of basic staple food crops including yams, dried and smoked fish, potatoes and onions through pilot scale experiments carried out in some African countries.

There have been positive developments on food irradiation in different regions of the world, especially in the United States of America and several Asian and Latin American countries. In some countries in Africa, this technology has been studied in the past few decades with encouraging results. To assist these countries in conducting pilot scale research and development on irradiation of specific commodities of interest to them including market testing and feasibility to establish commercial irradiators for multi-purpose application, a Coordinated Research Project (CRP) on Impact of Irradiation to Prevent Food Losses in Africa was carried out between 1995 and 1999. This CRP demonstrated that food irradiation has a potential to reduce losses of basic staple food crops including yams, dried and smoked fish, potatoes and onions through pilot scale experiments carried out in some African countries. Small scale market testing of such irradiated food such as spices, potatoes and onions showed encouraging results. In some countries (Cote d'Ivoire, Egypt, Ghana, Senegal and South Africa), it is feasible to establish commercial irradiation facilities for treating food. In Morocco, irradiation shows a potential to meet quarantine requirements in international food trade. It should be noted that commercial scale application of irradiation of some food products has been carried out in South Africa since the 1980s.

At the beginning of spring in the northern hemisphere, the situation in agricultural markets relaxes visibly. After the year 2012 was characterized by periods of drought in the United States and some Eastern European countries, in recent months good harvests in major producing countries in the southern hemisphere have provided that the stocks of major agricultural commodities are grown again. Thus, enough resources are still available for the supply of food and energy. There still exists land potential in Europe and on other continents for the use of bio-energy. In addition to new power plant crops, known arable crop cultures contribute to the exploration of such a potential: An example of this is the sugar beet. The view on the global supply balance in agricultural goods inter alia the major staple food rice shows that there exist large surpluses on the food markets. However, these surpluses do not benefit the hungry persons in the world. Hunger is a problem of distribution which is not associated with the growth of bio-energy.

Antiviral activity of α-helical stapled peptides designed from the HIV-1 capsid dimerization domain

Directory of Open Access Journals (Sweden)

Cowburn David

2011-05-01

Full Text Available Abstract Background The C-terminal domain (CTD of HIV-1 capsid (CA, like full-length CA, forms dimers in solution and CTD dimerization is a major driving force in Gag assembly and maturation. Mutations of the residues at the CTD dimer interface impair virus assembly and render the virus non-infectious. Therefore, the CTD represents a potential target for designing anti-HIV-1 drugs. Results Due to the pivotal role of the dimer interface, we reasoned that peptides from the α-helical region of the dimer interface might be effective as decoys to prevent CTD dimer formation. However, these small peptides do not have any structure in solution and they do not penetrate cells. Therefore, we used the hydrocarbon stapling technique to stabilize the α-helical structure and confirmed by confocal microscopy that this modification also made these peptides cell-penetrating. We also confirmed by using isothermal titration calorimetry (ITC, sedimentation equilibrium and NMR that these peptides indeed disrupt dimer formation. In in vitro assembly assays, the peptides inhibited mature-like virus particle formation and specifically inhibited HIV-1 production in cell-based assays. These peptides also showed potent antiviral activity against a large panel of laboratory-adapted and primary isolates, including viral strains resistant to inhibitors of reverse transcriptase and protease. Conclusions These preliminary data serve as the foundation for designing small, stable, α-helical peptides and small-molecule inhibitors targeted against the CTD dimer interface. The observation that relatively weak CA binders, such as NYAD-201 and NYAD-202, showed specificity and are able to disrupt the CTD dimer is encouraging for further exploration of a much broader class of antiviral compounds targeting CA. We cannot exclude the possibility that the CA-based peptides described here could elicit additional effects on virus replication not directly linked to their ability to bind

Documenting the spectrum of ecosystem management, the roles of forestry and agricultural biodiversity, TEK, and human culture for food sovereignty, are all priority challenges for contemporary science and society. Ethnoagroforestry is a research approach that provides a theoretical framework integrating socio-ecological disciplines and TEK. We analyze in this study general types of Agroforestry Systems of México, in which peasants, small agriculturalist, and indigenous people are the main drivers of AFS and planning of landscape diversity use. We analyzed the actual and potential contribution of ethnoagroforestry for maintaining diversity of wild and domesticated plants and animals, ecosystems, and landscapes, hypothesizing that ethnoagroforestry management forms may be the basis for food sufficiency and sovereignty in Mexican communities, regions and the whole nation. We conducted research and systematization of information on Mexican AFS, traditional agriculture, and topics related to food sovereignty from August 2011 to May 2015. We constructed the database Ethnoagroforestry based on information from our own studies, other databases, Mexican and international specialized journals in agroforestry and ethnoecology, catalogues and libraries of universities and research centers, online information, and unpublished theses. We analyzed through descriptive statistical approaches information on agroforestry systems of México including 148 reports on use of plants and 44 reports on use of animals. Maize, beans, squashes and chili peppers are staple Mesoamerican food and principal crops in ethnoagroforestry systems practiced by 21 cultural groups throughout Mexico (19 indigenous people) We recorded on average 121 ± 108 (SD) wild and domesticated plant species, 55 ± 27% (SD) of them being native species; 44 ± 23% of the plant species recorded provide food, some of them having also medicinal, firewood and fodder uses.

Full Text Available Subsistence Bhutanese farmers spread across different agro-ecological zones maintain large species and varietal diversity of different crops in their farm. However, no studies have been undertaken yet to assess why farmers conserve and maintain large agro-biodiversity, the extent of agro-ecological richness, species richness, estimated loss of traditional varieties and threats to the loss of on-farm agro-biodiversity. Information on the number of varieties cultivated by the farmers for six important staple crops were collected from nine districts and twenty sub-districts spread across six different agro-ecological zones of the country to understand farmers reasons for maintaining on-farm crop diversity, estimate agro-ecological richness, species richness and the overall loss of traditional varieties, to know the famers’ level of awareness on climate change and the different threats to crop diversity. The results from this study indicated that an overwhelming 93% of the respondents manage and use agro-biodiversity for household food security and livelihood. The average agro-ecological richness ranged from 1.17 to 2.26 while the average species richness ranged from 0.50 to 2.66. The average agro-ecological richness indicates a large agro-ecological heterogeneity in terms of the different species of staple crops cultivated. The average species richness on the other hand shows that agro-ecological heterogeneity determines the type and extent of the cultivation of the six different staple cereals under consideration. The overall loss of traditional varieties in a time period of 20 years stands at 28.57%. On climate change, 94% of the farmers recognize that local climate is changing while 86% responded that they are aware of the potential impacts of climate change on their livelihoods. Climate change and associated factors was considered the most imminent threat to the management and loss of on-farm agro-biodiversity. The results from this study

Extension of shelf life and preservation of products are both very important for the food industry. However, just as with other processes, speed and higher manufacturing performance are also beneficial. Although microwave heating is utilized in a number of industrial processes, there are many unanswered questions about its effects on foods. Here we analyze whether the effects of microwave heating with continuous flow are equivalent to those of traditional heat transfer methods. In our study, the effects of heating of liquid foods by conventional and continuous flow microwave heating were studied. Among other properties, we compared the stability of the liquid foods between the two heat treatments. Our goal was to determine whether the continuous flow microwave heating and the conventional heating methods have the same effects on the liquid foods, and, therefore, whether microwave heat treatment can effectively replace conventional heat treatments. We have compared the colour, separation phenomena of the samples treated by different methods. For milk, we also monitored the total viable cell count, for orange juice, vitamin C contents in addition to the taste of the product by sensory analysis. The majority of the results indicate that the circulating coil microwave method used here is equivalent to the conventional heating method based on thermal conduction and convection. However, some results in the analysis of the milk samples show clear differences between heat transfer methods. According to our results, the colour parameters (lightness, red-green and blue-yellow values) of the microwave treated samples differed not only from the untreated control, but also from the traditional heat treated samples. The differences are visually undetectable, however, they become evident through analytical measurement with spectrophotometer. This finding suggests that besides thermal effects, microwave-based food treatment can alter product properties in other ways as well.

Climate change influences on the major pillars of food security. Each of the four elements of food security (availability,access,utilization,andstability) is vulnerable to changes in climate. For example,reductions in production related to regional drought influence food availability at multiple scales. Changes in price influences the ability of certain populations to purchase food (access). Utilization maybe affected when production zones shift, reducing the availability of preferred or culturally appropriate types of food within a region. Stability of the food supply may be highly uncertain given an increased incidence of extreme climatic events and their influence on production patterns.

Sharma, Sakshi; Nagpal, Avinash Kaur; Kaur, Inderpreet

2018-07-30

In the present study, an assessment of heavy metal content in soil and food crops (wheat, rice, maize grains and mustard seeds) and associated health risks was carried out for residents of Ropar wetland and its environs. All the soil samples had high cadmium and cobalt contents, whereas, all crop samples had high contents of cobalt and lead. Bioconcentration factor (BCF) analysis indicated that rice grains act as hyper-accumulators of chromium (BCF = 17.98) and copper (BCF = 10.91), whereas, maize grains act as hyper-accumulators of copper (BCF = 30.43). One-way ANOVA suggested that heavy metal content in food crops varied significantly at p ≤ 0.05 for different sites, indicating anthropogenic contribution of heavy metals in agricultural fields. Dietary intake of cobalt via all food crops posed higher non-cancer health risk to residents in comparison to other heavy metals. Chromium posed highest cancer risk through consumption of wheat grains, being staple diet in study area. Copyright © 2018 Elsevier Ltd. All rights reserved.

We compared MRI findings in the shoulder with arthroscopic findings of the anterior part of inferior gleno-humeral ligament (AIGHL) in 49 shoulders showing traumatic anterior instability (TAI). Arthroscopic findings were classified into two types according to whether the AIGHL is adequately wide and thick for arthroscopic staple capsulorrhaphy (ASC). MRI findings were graded into two types according to the continuity of the articular capsule in 23 shoulders examined by MR arthrograms and according to the morphology of the anterior labrum in 26 examined by conventional MRI. In each shoulder, two or three different sections containing the anteroinferior area of the glenoid were evaluated. MRI findings were significantly correlated with arthroscopic findings. Both MR arthrograms and conventional MRI are useful for determining the indications for ASC. (author)

Food irradiation

International Nuclear Information System (INIS)

Beishon, J.

1991-01-01

Food irradiation has been the subject of concern and controversy for many years. The advantages of food irradiation include the reduction or elimination of dangerous bacterial organisms, the control of pests and insects which destroy certain foods, the extension of the shelf-life of many products, for example fruit, and its ability to treat products such as seafood which may be eaten raw. It can also replace existing methods of treatment which are believed to have hazardous side-effects. However, after examining the evidence produced by the proponents of food irradiation, the author questions whether it has any major contribution to make to the problems of foodborne diseases or world food shortages. More acceptable solutions, he suggests, may be found in educating food handlers to ensure that hygienic conditions prevail in the production, storage and serving of food. (author)

Food Prices and Climate Extremes: A Model of Global Grain Price Variability with Storage

Science.gov (United States)

Otto, C.; Schewe, J.; Frieler, K.

2015-12-01

Extreme climate events such as droughts, floods, or heat waves affect agricultural production in major cropping regions and therefore impact the world market prices of staple crops. In the last decade, crop prices exhibited two very prominent price peaks in 2007-2008 and 2010-2011, threatening food security especially for poorer countries that are net importers of grain. There is evidence that these spikes in grain prices were at least partly triggered by actual supply shortages and the expectation of bad harvests. However, the response of the market to supply shocks is nonlinear and depends on complex and interlinked processes such as warehousing, speculation, and trade policies. Quantifying the contributions of such different factors to short-term price variability remains difficult, not least because many existing models ignore the role of storage which becomes important on short timescales. This in turn impedes the assessment of future climate change impacts on food prices. Here, we present a simple model of annual world grain prices that integrates grain stocks into the supply and demand functions. This firstly allows us to model explicitly the effect of storage strategies on world market price, and thus, for the first time, to quantify the potential contribution of trade policies to price variability in a simple global framework. Driven only by reported production and by long--term demand trends of the past ca. 40 years, the model reproduces observed variations in both the global storage volume and price of wheat. We demonstrate how recent price peaks can be reproduced by accounting for documented changes in storage strategies and trade policies, contrasting and complementing previous explanations based on different mechanisms such as speculation. Secondly, we show how the integration of storage allows long-term projections of grain price variability under climate change, based on existing crop yield scenarios.

2017-07-26

Here we present a method for the accurate quantification of major volatile metabolites found in different food and beverages, including ethanol, acetic acid and other aroma compounds, using gas chromatography coupled to mass spectrometry (GC-MS). The method is combined with a simple sample preparation procedure using sodium chloride and anhydrous ethyl acetate. The GC-MS analysis was accomplished within 4.75 min, and over 80 features were detected, of which 40 were positively identified using an in-house and a commercialmass spectrometry (MS) library. We determined different analytical parameters of these metabolites including the limit of detection (LOD), limit of quantitation (LOQ) and range of quantification. In order to validate the method, we also determined detailed analytical characteristics of five major fermentation end products including ethanol, acetic acid, isoamyl alcohol, ethyl-L-lactate and, acetoin. The method showed very low technical variability for the measurements of these metabolites in different matrices (<3%) with an excellent accuracy (100% ± 5%), recovery (100% ± 10%), reproducibility and repeatability [Coefficient of variation (CV) 1-10%)]. To demonstrate the applicability of the method, we analysed different fermented products including balsamic vinegars, sourdough, distilled (whisky) and non-distilled beverages (wine and beer).

Food Abundance Is the Main Determinant of High-Altitude Range Use in Snub-Nosed Monkeys

Full Text Available High-altitude dwelling primates have to optimize navigating a space that contains both a vertical and horizontal component. Black-and-white or Yunnan snub-nosed monkeys (Rhinopithecus bieti are extreme by primate standards in inhabiting relatively cold subalpine temperate forests at very high altitudes where large seasonal variation in climate and food availability is expected to profoundly modulate their ranging strategies so as to ensure a positive energy balance. A “semi-nomadic” group of R. bieti was followed for 20 months in the montane Samage Forest, Baimaxueshan Nature Reserve, Yunnan, PRC, which consisted of evergreen conifers, oaks, and deciduous broadleaf trees. The aim of this study was to disentangle the effects of climate and phenology on patterns of altitudinal range use. Altitude used by the group ranged from a maximum of 3550 m in July 2007 to a minimum of 3060 m in April 2006. The proportional use of lichen, the monkeys’ staple fallback food, in the diet explained more variation in monthly use of altitudes than climatic factors and availability of flush and fruit. The abundance of lichens at high altitudes, the lack of alternative foods in winter, and the need to satisfy the monkey's basal energetic requirements explain the effect of lichenivory on use of altitudes.

Mineral content as a basis for food selection by western lowland gorillas in a forest clearing.

Magliocca, Florence; Gautier-Hion, Annie

2002-06-01

The forests in northwest Republic of Congo contain a number of herbaceous swamp clearings that provide foraging sites for lowland gorillas (G.g. gorilla). A 10-month study at the Maya Nord clearing (Parc National d'Odzala) showed that feeding activities occupied 72% of the time visiting gorillas spent on the clearing. They fed on four plant species: Enydra fluctuans (Asteraceae), Cyperus sp., Pycreus mundtii, and Rhynchospora corymbosa (Cyperaceae) among the 45 species recorded on the clearing. These clearing food species have higher mineral contents (especially Na and Ca) than the dominant Marantaceae species (Haumania liebrechtsiana) that constituted a staple food plant for gorillas in this forest. They also have higher potassium contents and contain less lignin than non-eaten clearing items/species. Finally, the most actively searched for clearing food (Enydra fluctuans) was characterized by the highest amount of Na and Ca. These results suggest that the mineral content (especially in Na, Ca, and/or K) could determine the feeding selectivity of gorillas at the clearing. They also tend to confirm that the amount of fiber plays a deterrent role in food selectivity, as has been found by many authors. The high density of gorillas in that region could result from the combination of the large areas of Marantaceae forests that provide abundant though monotonous food, and the number of clearings that provide sufficient mineral supplies. Clearings should thus be considered as key habitats for the conservation of gorillas. Copyright 2002 Wiley-Liss, Inc.

Food availability after nuclear war

International Nuclear Information System (INIS)

Cropper, W.P. Jr.; Harwell, M.A.

1985-01-01

The analysis of acute-phase food shortage vulnerabilities for 15 countries clearly indicates that in many countries massive levels of malnutrition and starvation are a possible outcome of a major nuclear war. The principal direct cause of such food shortages would be the climatic disturbances and societal disruptions during the initial post-war year. Even without climatic disturbances, import-dependent countries could suffer food shortages. Many of the countries with the highest levels of agricultural production and storage would probably be targets of nuclear weapons. It seems unlikely that food exports would continue from severely damaged countries, thus propagating effects to non-combatant countries. A similar analysis of food storage vulnerability in 130 countries indicates that a majority of people live in countries with inadequate food stores for such major perturbations. This is true even if consumption rates of 1,000 kcal . person/sup -1/ . day/sup -1/ are assumed rather than 1,500 kcal . person/sup -1/ . day/sup -1/. This vulnerability is particularly severe in Africa, and South America. Even though most of the countries of these continents have no nuclear weapons and are not likely to be targeted, the human consequences of a major nuclear war could be nearly as severe as in the principal combatant countries. Few countries would have sufficient food stores for their entire population and massive mortality would result if only pre-harvest levels were available. These conclusions represent an aspect of nuclear war that has only been recently realized. The possibility of climatic disturbances following a large nuclear war has introduced a new element to the global consequences expected. Not only are the populations of the major combatant countries at risk in a nuclear exchange, but also most of the global human population

Elaidic acid is the main unnatural trans fatty acid isomer occurring during partial hydrogenation of vegetable oils used as ingredients for the formulation of processed foods. The main objective is to assess associations between processed food intakes and plasma phospholipid elaidic acid concentrations within the European Prospective Investigation into Cancer and Nutrition study. A cross-sectional study was used to determine fatty acid profiles in 3,003 subjects from 16 centers. Single 24-h dietary recalls (24-HDR) were collected using a standardized computerized interview program. Food intakes were computed according to their degree of processing (moderately/nonprocessed foods, processed staple foods, highly processed foods). Adjusted ecological and individual correlations were calculated between processed food intakes and plasma elaidic acid levels. At the population level, mean intakes of highly processed foods were strongly correlated with mean levels of plasma elaidic acid in men (P = 0.0016) and in women (P = 0.0012). At the individual level, these associations remained but at a much lower level in men (r = 0.08, P = 0.006) and in women (r = 0.09, P = 0.0001). The use of an averaged 24-HDR measure of highly processed food intakes is adequate for predicting mean levels of plasma elaidic acid among European populations.

Full Text Available People’s diets have changed greatly in the rural north China during the 60 years since the founding of PRC, present the gradual characteristics obviously. In the previous 30 years, people almost continue the traditional way, and they had bland diet but just could barely feed themselves. In the leaner year, people had to allay their hunger with those which could be eaten. More unfortunately, they even had nothing to eat, and always died of cholera. In the later 30 years, their dietary changes speed up further, staple and non-staple foods were becoming more and more abundant, and people’s life gradually improved, especially after implementation of the household contract responsibility system. The proportions of non-staple foods increase gradually, people have pursued not only nutrition, but also good health. They have increased their consumption of meat, eggs. What’s more, security problem about food have aroused widespread concerns. Although their diets have become modern day by day but they have not given up the traditional diet. They began to emphasize the balance of refined food and grains, meats and vegetables, even the nutritional health. There were some new trends in consumer’s needs, including the green consumption, healthy consumption, and civilized consumption.

Food security and environmental degradation in northern Nigeria: demographic perspectives.

Science.gov (United States)

Lockwood, M

1991-07-01

The Malthusian controversy about the causes of environmental change and food insecurity in Hausaland in northern Nigeria is examined. The argument is irresolvable based on available data at the macro level. The individual and household level are appropriate for answering the question about how high density populations survive on a savannah. To understand population pressure in Hausaland, it is important to read Malthus very carefully and to understand the existing demographic structure in which economic and kinship relations support high fertility even where land is scarce. Demographic responses vary with economic strata. Policies ignore individual level differences. Since 1953, the densely populated areas of Sokoto, Katsina, Zaria, and Kano have spread in an area that is largely dry with a moderate-to-high risk of desertification. Food insecurity exists not only in times of drought, but also annually in the form of chronic shortages of staples for poor farmers. Average land holdings/capita have become smaller. Population pressure has also contributed to shifts in land use. Food prices have increased. Possible explanations include 1) the drought and the oil boom have a greater impact on environmental change and food insecurity and rural Hausa farmers have responded by raising yields, managing tree resources, and practicing soil conservation and 2) an independent source of income from non-agricultural activities is an essential part of the economy. The relationship among population pressure, land shortage, and food insecurity is complex. It is inaccurate to label Hausa as subsistence farmers, when trading in grain is an important enterprise. The role that commercialization of agriculture plays in food insecurity is discussed. Malthusian disaster is not imminent. The proximate determinants of fertility, birth spacing practices and infertility, should lead to high fertility rates, but in this case they do not. Determinants responsive to economic factors tend to be

Global and Country-Level Fragility to Major Disruptions in Crop Production

New food polices are needed to mitigate vulnerabilities in the global food system to unexpected and severe production losses. The starting point for developing such policies is the ability to quantify the potential range of food and economic losses associated with major food-production shocks. Although individual major shock events are unpredictable, it is possible to quantify the relative vulnerabilities of the global food system as a whole and of individual countries within the system to production shocks. Here we combine a scale for food disruptions, which links the magnitude for a production shock with the corresponding short-term food and economic losses for that event (analogous to the well-known Richter magnitude scale for earthquakes), with country-level food system metrics. We demonstrate the value of our approach using the recent El Niño event of 2015-2016. Ultimately, these metrics can be used as part of efforts to develop national and global level food policies to prepare for and mitigate possible food-supply disruptions.

Empowering billions with food safety and food security

International Nuclear Information System (INIS)

Pillai, Suresh D.

2009-01-01

Full text: There are virtually millions of people -who die needlessly every year due to contaminated water and food. There are virtually many millions more who are starving due to an inadequate supply of food. Billions of pounds of food are unnecessarily wasted due to insect and other damage. Deaths and illness due to contaminated food or inadequate food are at catastrophic levels in many regions of the world. A majority of the food and water borne illnesses and deaths are preventable. It can be prevented by improved food production methods, improved food processing technologies, improved food distribution systems and improved personal hygiene. Food irradiation technology is over 100 years old. Yet, this technology is poorly understood by governments and corporate decision makers all around the world. Many consumers also are unfortunately misinformed of this technology. There is an urgent need for nations and people around the world to empower themselves with the knowledge and the expertise to harness this powerful technology. Widespread and sensible adoption of this technology can empower billions around the world with clean and abundant food supplies. It is unconscionable in the 21st century for governments to allow people to die or go hungry when the technology to prevent them is readily available

Full Text Available Introduction. Aim of the study was trying to draw a final flow chart for the management of gastric leaks after laparoscopic sleeve gastrectomy, based on the review of our cases over 10 years’ experience. Material and Methods. We retrospectively reviewed all patients who underwent LSG as a primary operation at the Bariatric Unit of Tor Vergata University Hospital in Rome from 2007 to 2015. Results. Patients included in the study were 418. There were 6 staple line leaks (1.44%. All patients with diagnosis of a leak were initially discharged home in good clinical conditions and then returned to A&E because of the complication. The mean interval between surgery and readmission for leak was 13,4 days (range 6–34 days, SD ± 11.85. We recorded one death (16.67% due to sepsis. The remaining five cases were successfully treated with a mean healing time of the gastric leak of 55,5 days (range 26–83 days; SD ± 25.44. Conclusion. Choosing the proper treatment depends on clinical stability and on the presence or not of collected abscess. Our treatment protocol showed being associated with low complication rate and minor discomfort to the patients, reducing the need for more invasive procedures.

Food scares have diminished trust in public institutions to guarantee food safety. Food governance after the food scare era is concerned with institutional independence and transparency leading to a hybrid of public and private sector management and to mechanisms for consumer involvement in food governance. This paper explores Australian consumers' perceptions of who is, and should be responsible for food safety. Forty-seven participants were interviewed as part of a larger study on trust in the food system. Participants associate food governance with government, industry, and the individual. While few participants can name the national food regulator, there is a strong belief that the government is responsible for regulating the quality and safety of food. Participants are wary of the role of the food industry in food safety, believing that profit motives will undermine effective food regulation. Personal responsibility for food safety practices was also identified. While there are fewer mechanisms for consumer involvement and transparency built into the food governance system, Australian consumers display considerable trust in government to protect food safety. There is little evidence of the politicisation of food, reflecting a level of trust in the Australian food governance system that may arise from a lack of exposure to major food scares.

The role of sweet and savoury taste in food intake and food preferences

Background and aim The sensory attributes of food play a key role in the selection and termination of meals and their rewarding properties. The majority of our foods are either sweet or savoury tasting. In addition, within our food range, savoury-tasting foods contain in general higher levels of protein. The effect of specific taste modalities on human food intake, however, requires further clarification. The primary aim of this thesis was to investigate the role of sweet and savoury taste ...

Food synergies for improving bioavailability of micronutrients from plant foods.

Science.gov (United States)

Nair, K Madhavan; Augustine, Little Flower

2018-01-01

Plant foods are endowed with micronutrients but an understanding of bioavailability is essential in countries primarily dependent on plant based foods. Bioavailability depends majorly on food synergies. This review examines the nature of certain food synergies and methods to screen and establish it as a strategy to control micronutrient deficiency in the populations. Strong evidence on the synergistic effect of inclusion of vitamin C rich fruits and non-vegetarian foods in enhancing the bioavailability of iron has been demonstrated. Fat is found to be synergistic for vitamin A absorption. Red wine and protein have been explored for zinc absorption and effect of fat has been studied for vitamin D. Methods for screening of bioavailability, and biomarkers to demonstrate the synergistic effects of foods are required. Translation of food synergy as a strategy requires adaptation to the context and popularization of intelligent food synergies. Copyright © 2016 Elsevier Ltd. All rights reserved.

2013-03-01

In the U.S., poverty has been linked to both obesity and disease burden. Latinos in the U.S. are disproportionately affected by poverty, and over the past 10 years, the percentage of overweight U.S. Latino youth has approximately doubled. Buying low-cost food that is calorie-dense and filling has been linked to obesity. Low-income individuals tend to favor energy-dense foods because of their low cost, and economic decisions made during food purchasing have physiologic repercussions. Diets based on energy-dense foods tend to be high in processed staples, such as refined grains, added sugars, and added fats. These diets have been linked to a higher risk of obesity, type 2 diabetes, and cardiovascular disease. This pilot study conducted ethnographic qualitative analyses combined with quantitative analyses to understand grocery shopping practices among 20 Spanish-speaking, low-income Latino families. The purpose was to analyze food selection practices in order to determine the effect of nutrition education on changes in shopping practices to later develop educational tools to promote selection of healthier food options. Participants received tailored, interactive, nutrition education during three to five home visits and a supermarket tour. Grocery store receipts for grocery purchases collected at baseline and at the end of the project were analyzed for each family to extract nutritional content of purchased foods. Nutritional content was measured with these factors in mind: quantity, calories, fats, carbohydrates, fiber, protein, and percentage of sugary beverages and processed food. Data were collected in 2010-2011 and analyzed in 2011-2012. After receiving between three and five home-based nutrition education sessions and a supermarket tour over a 6-month period, many families adopted instructions on buying budget-friendly, healthier alternative foods. Findings indicate that participating families decreased the total number of calories and calories per dollar

Pyrrolizidine alkaloids in food: a spectrum of potential health consequences.

Edgar, J A; Colegate, S M; Boppré, M; Molyneux, R J

Contamination of grain with 1,2-dehydropyrrolizidine ester alkaloids (dehydroPAs) and their N-oxides is responsible for large incidents of acute and subacute food poisoning, with high morbidity and mortality, in Africa and in central and south Asia. Herbal medicines and teas containing dehydroPAs have also caused fatalities in both developed and developing countries. There is now increasing recognition that some staple and widely consumed foods are sometimes contaminated by dehydroPAs and their N-oxides at levels that, while insufficient to cause acute poisoning, greatly exceed maximum tolerable daily intakes and/or maximum levels determined by a number of independent risk assessment authorities. This suggests that there may have been cases of disease in the past not recognised as resulting from dietary exposure to dehydroPAs. A review of the literature shows that there are a number of reports of liver disease where either exposure to dehydroPAs was suspected but no source was identified or a dehydroPA-aetiology was not considered but the symptoms and pathology suggests their involvement. DehydroPAs also cause progressive, chronic diseases such as cancer and pulmonary arterial hypertension but proof of their involvement in human cases of these chronic diseases, including sources of exposure to dehydroPAs, has generally been lacking. Growing recognition of hazardous levels of dehydroPAs in a range of common foods suggests that physicians and clinicians need to be alert to the possibility that these contaminants may, in some cases, be a possible cause of chronic diseases such as cirrhosis, pulmonary hypertension and cancer in humans.

2012-11-01

Microbial food safety remains a major economic and public health concern in Arab countries. Over the past several years, many of these countries have attempted to revise and upgrade food quality control and surveillance programs; however, these systems vary in scope and effectiveness. This review addresses the major reported foodborne outbreaks and multidrug resistance of pathogenic microorganisms isolated from food products. Major foodborne pathogens of concern included Brucella spp., Clostridium botulinum, fecal coliforms, Escherichia coli O157:H7, Listeria monocytogenes, Salmonella, and Staphylococcus aureus. Measures for managing microbial food hazards based on a comprehensive risk analysis also are proposed.

Xing, Guan Hua; Wu, Sheng Chun; Wong, Ming Hung

2010-11-01

The levels of PCBs in different types of food (fish, shellfish, meat, rice, vegetables, and fruits) were analyzed to determine the dietary intake of 37 PCBs for local residents and e-waste workers (all lactating mothers) at Taizhou (China), a major electronic waste scrapping center, in particular for recycling transformers. The exposure to PCBs through dietary intake in Taizhou was estimated at 92.79 ngkg(-1)d(-1), contributed by consumption of freshwater fish (28%), rice (28%), meat (17%), shellfish (9%), vegetables (8%), egg (4%) and marine fish (2%). With regards to WHO-PCB-TEQ values, freshwater fish (40%), shellfish (24%), duck liver (18%) and rice (12%) were the main dietary sources with total daily intake (9.78 pg WHO-PCB-TEQ kg(-1)d(-1)), exceeding the FAO/WHO Tolerable Daily Intake (70 pg TEQkg(-1)body(-1)wt(-1)month(-1)).
