Education, tobacco smoking, alcohol consumption, and IL-2 and IL-6 gene polymorphisms in the survival of head and neck cancer

The association of education, tobacco smoking, alcohol consumption, and interleukin-2 (IL-2 +114 and -384) and -6 (IL-6 -174) DNA polymorphisms with head and neck squamous cell carcinoma (HNSCC) was investigated in a cohort study of 445 subjects. IL-2 and IL-6 genotypes were determined by real-time PCR. Cox regression was used to estimate hazard ratios (HR) and 95% confidence intervals (95%CI) of disease-specific survival according to anatomical sites of the head and neck. Mean age was 56 years and most patients were males (87.6%). Subjects with 5 or more years of schooling had better survival in larynx cancer. Smoking had no effect on HNSCC survival, but alcohol consumption had a statistically significant effect on larynx cancer. IL-2 gene +114 G/T (HR = 0.52; 95%CI = 0.15-1.81) and T/T (HR = 0.22; 95%CI = 0.02-3.19) genotypes were associated with better survival in hypopharynx cancer. IL-2 +114 G/T was a predictor of poor survival in oral cavity/oropharynx cancer and larynx cancer (HR = 1.32; 95%CI = 0.61-2.85). IL-2 -384 G/T was associated with better survival in oral cavity/oropharynx cancer (HR = 0.80; 95%CI = 0.45-1.42) and hypopharynx cancer (HR = 0.68; 95%CI = 0.21-2.20), but an inverse relationship was observed for larynx cancer. IL-6 -174 G/C was associated with better survival in hypopharynx cancer (HR = 0.68; 95%CI = 0.26-1.78) and larynx cancer (HR = 0.93; 95%CI = 0.42-2.07), and C/C reduced mortality in larynx cancer. In general, our results are similar to previous reports on the value of education, smoking, alcohol consumption, and IL-2 and IL-6 genetic polymorphisms for the prognosis of HNSCC, but the risks due to these variables are small and estimates imprecise.

Stability studies and shelf life estimation of a soy-based dessert

This work is aimed at evaluating the physicochemical, physical, chromatic, microbiological, and sensorial stability of a non-dairy dessert elaborated with soy, guava juice, and oligofructose for 60 days at refrigerated storage as well as to estimate its shelf life time. The titrable acidity, pH, instrumental color, water activity, ascorbic acid, and physical stability were measured. Panelists (n = 50) from the campus community used a hedonic scale to assess the acceptance, purchase intent, creaminess, flavor, taste, acidity, color, and overall appearance of the dessert during 60 days. The data showed that the parameters differed significantly (p < 0.05) from the initial time, and they could be fitted in mathematical equations with coefficient of determination above 71%, aiming to consider them suitable for prediction purposes. Creaminess and acceptance did not differ statistically in the 60-day period; taste, flavor, and acidity kept a suitable hedonic score during storage. Notwithstanding, the sample showed good physical stability against gravity and presented more than 15% of the Brazilian Daily Recommended Value of copper, iron, and ascorbic acid. The product shelf life estimation found was 79 days considering the overall acceptance, acceptance index and purchase intent.

Effect of different covering materials used during the pre-harvest stage on the quality and storage life of 'Sultana Seedless' grapes

Covering the grapevine rows to delay the maturity and harvest date became widely practiced in 'Sultana Seedless' vineyards. The research work was conducted to test different cover materials (polypropylene cross-stitch, life pack, mogul and transparent polyethylene) in respect to their effects on grape quality and storability. Harvest was delayed for one month in covered plots. Harvested grapes were packed and transferred to storage rooms after pre-cooling. During packing, the grape clusters were sealed in PE bags with sulphur dioxide pads. The grapes were stored for 90 days in the first year and 120 days in the second year, at -0.5ºC and 90% RH. All the grape clusters were healthy and of marketable quality after 90 days of storage period. In the first year, at the end of the storage, only those grapes harvested from the rows covered with polypropylene cross-stitch showed fungal growth. The sensory quality scores revealed a lower level of preference after 120 days of storage. The effects of the covering materials tested were similar regarding grape quality and storage performance except the transparent polyethylene that damaged the grapevine leaves.

Quality indicators and shelf life of red octopus (Octopus maya) in chilling storage

Abstract There are no precedents concerning the quality of Octopus maya during chilled storage. This study evaluated the shelf life of the red octopus in chilling storage (4oC) and the correlation of the sensory quality index with microbiological counting and the biochemical indicators (hypoxanthine, histamine and volatile amines). A total of 112 whole raw octopi (average weight of 896 g) were randomly selected from seven batches and exposed to 4°C for 18, 24, 48, 72, 84, 96, and 100 h. The histamine concentration (91.7%), followed by the counts of psychrotrophic bacteria (5.5%) and hypoxanthine (2.2%), were the predictors from the redundancy analysis that better explained the changes taking place during the chilling hours. After 72 h of chilling, the microbial count was determined to be log 4.7 CFU/g, and the octopus samples were classified as B quality (minor sensory quality defects) based on the sensory quality scale. Although the samples were not classified as unacceptable at 100 h of refrigeration by the sensory index, the level of histamine reached the defect action level (5 mg/100 g) as ruled by the International Food Safety Authorities. The shelf life of the red octopus in chilling storage was predicted to be 119 h.

The relationship between fructose consumption and risk of obesity in two Aboriginal populations

Résumé La prédominance de l'obésité qui touche les enfants et les adultes a augmenté dans le monde entier ces dernières décennies. Les différentes études épidémiologiques ont prouvé que l'obésité est devenue une préoccupation profonde de santé aux États-Unis et au Canada. Il a été montré que l'obésité a beaucoup d’effets sur la santé ainsi il serait important de trouver différentes causes pour le gain de poids. Il est clair que l'obésité soit la condition de multiples facteurs et implique des éléments génétiques et environnementaux. Nous nous concentrons sur les facteurs diététiques et particulièrement le fructose où sa consommation a parallèlement augmenté avec l'augmentation du taux d'obésité. La forme principale du fructose est le sirop de maïs à haute teneur en fructose (HFCS) qui est employé en tant qu'édulcorant primordial dans la plupart des boissons et nourritures en Amérique du Nord. Il a été suggéré que la prise du fructose serait probablement un facteur qui contribue à l’augmentation de la prédominance de l'obésité. L'objectif de cette étude était d'évaluer s'il y a un rapport entre la consommation du fructose et le risque d'obésité. Nous avons travaillé sur deux bases de données des nations Cree et Inuit. Nous avons eu un groupe de 522 adultes Cree, (263 femmes et 259 hommes) dans deux groupes d'âge : les personnes entre 20 et 40 ans, et les personnes de 40 à 60 ans. Nous les avons classés par catégorie en quatre groupes d'indice de masse corporelle (IMC). L'outil de collecte de données était un rappel de 24 heures. En revanche, pour la base de données d'Inuit nous avons eu 550 adultes (301 femmes et 249 hommes) dans deux groupes d'âge semblables à ceux du Cree et avec 3 catégories d’indice de masse corporelle. Les données dans la base d'Inuit ont été recueillies au moyen de deux rappels de 24 heures. Nous avons extrait la quantité de fructose par 100 grammes de nourriture consommés par ces deux populations et nous avons créé des données de composition en nourriture pour les deux. Nous avons pu également déterminer les sources principales du fructose pour ces populations. Aucun rapport entre la consommation du fructose et l’augmentation de l’indice de masse corporelle parmi les adultes de Cree et d'Inuit n’a été détecté. Nous avons considéré l’apport énergétique comme facteur confondant potentiel et après ajustement, nous avons constaté que l'indice de masse corporelle a été associé à l’apport énergétique total et non pas à la consommation du fructose. Puisque dans les études qui ont trouvé une association entre la consommation de fructose et l’obésité, le niveau de la consommation de fructose était supérieure à 50 grammes par jour et comme dans cette étude ce niveau était inférieur à cette limite (entre 20.6 et 45.4 g/jour), nous proposons que des effets negatifs du fructose sur la masse corporelle pourraient être testés dans des populations à plus haute consommation. Les essais cliniques randomisés et éventuelles études cohortes avec différents niveaux de consommation de fructose suivis à long terme pourraient aussi être utiles. Mots clés : fructose, sirop de maïs à haute teneur en fructose (HFCS), obésité et poids excessif

When glaciers vanish : nature, power and moral order in the indian Himalayas

La présente thèse est une étude ethnographique qui examine le savoir en tant que pratique située au Ladakh, dans l’Himalaya indien. Elle analyse les implications socioculturelles des deux moteurs de changement en jeu au Ladakh: l’un est d'origine socio-économique et lié à la production du Ladakh en tant que zone frontalière, tandis que l’autre est de nature environnementale et entrainé par les changements climatiques. Alors que le Ladakh est demeuré hors de la portée de l’État bureaucratique pendant l’administration coloniale britannique, la région s’est trouvée reconfigurée en zone frontalière stratégique après l’indépendance de l’Inde des suites des guerres successives avec le Pakistan et la Chine. L’Indépendance a mené à la partition de l’Inde et du Pakistan en 1947; cette thèse examine la portée à long terme des évènements traumatisants de la partition tels qu’ils se sont déroulés au Ladakh et comment les Ladakhis établissent des liens entre ces évènements et les changements climatiques. L’État indien s’est produit dans la région à travers une volonté de dominer les montagnes, principalement par le développement d’infrastructures et par l’intégration du savoir local des Ladakhis dans l’appareil militaire. La militarisation a restructuré l'économie du Ladakh, redéfini la structure des ménages, contribué à l’exode rural, déplacé la centralité des activités agropastorales et, tel que la dissertation le soutient, altéré de manière significative la connexion de la population locale avec l'environnement. La rationalisation croissante de la perspective sur l’environnement aujourd'hui contribue à la fragmentation des liens qui unissent les domaines naturels et humains dans la cosmologie locale de même qu’à l'abandon des pratiques rituelles connexes. Parallèlement, la région est touchée par des effets distincts des changements climatiques, en particulier la récession des glaciers. La thèse juxtapose l'expérience subjective de ces vastes changements dans la vie quotidienne des villageois de la Vallée de Sham avec les faits historiques environnementaux, démontrant ainsi que les événements historiques locaux influent sur les perceptions des changements environnementaux. L'analyse démontre qu’un phénomène objectif tel que la récession des glaciers est interprété à travers des réalités locales. Plus précisément, selon la conception du monde locale, un glacier en retrait est une figure rhétorique d’une transformation de la condition humaine. Comme le fait valoir la dissertation, l’interprétation culturelle ne constitue pas un obstacle à l'objectivité de l'histoire naturelle de la cosmologie locale. L’interprétation culturelle et l'expérience empirique s’avèrent par ailleurs essentielles à la vitalité des connaissances locales sur l'environnement et à la performance des pratiques associées.

Investigations on the structural and operational changes of Ring Seine Fishing Systems of Kerala and its Life Cycle Assessment (lCA)

The study covers theFishing capture technology innovation includes the catching of aquatic animal, using any kind of gear techniques, operated from a vessel. Utilization of fishing techniques varies, depending upon the type of fisheries, and can go from a basic and little hook connected to a line to huge and complex mid water trawls or seines operated by large fishing vessels.The size and autonomy of a fishing vessel is largely determined by its ability to handle, process and store fish in good condition on board, and thus these two characteristics have been greatly influenced by the introduction and utilization of ice and refrigeration machinery. Other technological developments especially hydraulic hauling machinery, fish finding electronics and synthetic twines have also had a major impact on the efficiency and profitability of fishing vessels.A wide variety of fishing gears and practices ranging from small-scale artisanal to advanced mechanised systems are used for fish capture in Kerala. Most important among these fishing gears are trawls, seines, lines, gillnets and entangling nets and traps The modern sector was introduced in 1953 at Neendakara, Shakthikulangara region under the initiative of Indo-Norwegian project (INP). The novel facilities introduced in fishing industry by Indo- Norwegian project accordingly are mechanically operated new boats with new fishing nets. Soon after mechanization, motorization programme gained momentum in Kerala especially in Alleppey, Ernakulam and Kollam districts.

Pharmaceutical consumption and residuals potentially relevant to nutrient cycling in Greater Accra, Ghana

Recycling nutrients form sanitary wastes back into agricultural ecosystems offers an option to alleviate soil depletion in regions where the use of mineral fertiliser is limited. Exemplary nutrient and water cycling approaches, including collection, treatment and use of human urine, are established at Valley View University (VVU) in Greater Accra, Ghana. Concerns have been recently raised in regard to fate and impact of pharmaceutical residues in soils and interlinked environment. To evaluate in how far emerging knowledge can be transposed onto VVU, urban and rural environments in Greater Accra, spatial disease occurrence and drug consumption patterns were studied. Malaria has been found to represent the most severe health burden in Ghana, but there is also a high prevalence of infectious diseases. Drugs consumed in great quantities and in respect to their residual loads potentially problematic in the environment belong to therapeutic groups of: antibiotics, analgesics, drugs for diabetes, antimalarials, cardiovascular drugs and anthelmintics. Drug consumption revealed to be highest in urban and lowest in rural areas. At VVU the range of consumed drugs is comparable to urban areas except for the negligible use of diabetes and cardiovascular medication as well as contraceptives.

A DSGE model with loss aversion in consumption and leisure: an explanation for business cycles asymmetries

In this chapter, an asymmetric DSGE model is built in order to account for asymmetries in business cycles. One of the most important contributions of this work is the construction of a general utility function which nests loss aversion, risk aversion and habits formation by means of a smooth transition function. The main idea behind this asymmetric utility function is that under recession the agents over-smooth consumption and leisure choices in order to prevent a huge deviation of them from the reference level of the utility; while under boom, the agents simply smooth consumption and leisure, but trying to be as far as possible from the reference level of utility. The simulations of this model by means of Perturbations Method show that it is possible to reproduce asymmetrical business cycles where recession (on shock) are stronger than booms and booms are more long-lasting than recession. One additional and unexpected result is a downward stickiness displayed by real wages. As a consequence of this, there is a more persistent fall in employment in recession than in boom. Thus, the model reproduces not only asymmetrical business cycles but also real stickiness and hysteresis.
