Chemical composition, fatty acid profile and bioactive compounds of guava seeds (Psidium guajava L.)

This study aimed to characterize the chemical composition, determine the fatty acid profile, and quantify the bioactive compounds present in guava seed powder (Psidium guajava L.). The powder resulted from seeds obtained from guava pulp processing. The agro-industrial seeds from red guava cv. paluma were used, and they were donated by a frozen pulp fruit manufacturer. They contain varying amounts of macronutrients and micronutrients, with a high content of total dietary fiber (63.94 g/100g), protein (11.19 g/100g), iron (13.8 mg/100g), zinc (3.31 mg/100g), and reduced calorie content (182 kcal/100g). Their lipid profile showed a predominance of unsaturated fatty acids (87.06%), especially linoleic acid (n6) and oleic acid (n9). The powder obtained contained significant amounts of bioactive compounds such as ascorbic acid (87.44 mg/100g), total carotenoids (1.25 mg/100 g) and insoluble dietary fiber (63.55 g/100g). With regard to their microbiological quality, the samples were found suitable for consumption. Based on these results, it can be concluded that the powder produced has favorable attributes for industrial use, and that use of these seeds would be a viable alternative to prevent various diseases and malnutrition in our country and to reduce the environmental impact of agricultural waste.

Cajá-flavored drinks: a proposal for mixed flavor beverages and a study of the consumer profile

Mixed flavor beverages represent a trend that is gaining the allegiance of potential fruit juice consumers. The present study proposed to prepare mixed flavor beverages and verify their consumer acceptance. Cajá beverage (sample A) was used as the standard. The other beverages were prepared by mixing the cajá-flavored product with other flavors: strawberry (B), pineapple (C), jabuticaba (D), mango (E) and cashew (F). The consumer profiles in the two regions studied were similar. Overall beverages B, A and F were the most accepted, with scores of 7.7, 6.4 and 6.2, respectively. Internal Preference Mapping showed that most of the consumers were located near beverages A, B and F, confirming the acceptance results. The consumers indicated appearance and flavor as the most appreciated characteristics in beverages A, B and F. Beverages A, B and F presented higher total soluble solids contents and viscosities than the other beverages. Consumer segmentation did not depend on the different levels of familiarity with the cajá flavor. Thus the preparation of mixed flavor beverages of cajá-strawberry and cajá-cashew is an excellent proposal because it presents flavors with good potential for marketing in different regions of Brazil.

Sensory acceptability and fatty acid profile of fish crackers made from Carassius gibelio

Abstract In this study, our aim was to consider the production of fish crackers using Carassius gibelio and to investigate the fatty acid profile and sensory quality of the fish crackers. Fish cracker mixture with a ratio 3.5:1.5 (minced fish/wheat starch) was obtained. Based on the total minced fish and starch level, 1.75% salt, 0.25% black pepper, 2% sunflower oil, 1% baking powder and 10% cold water (4 °C) were added and stirred until a homogenous mixture was obtained. The mixture was compressed in an extractor and baked. The moisture content of minced fish (CMF), cracker dough (CD) and crackers (CCr) was 77.73 ± 0.14%, 63.10 ± 2.18% and 7.95 ± 0.67% respectively. The n6/n3 ratio of crackers was 2.61 ± 0.20, PUFA/SFA ratio 2.28 ± 0.06 and DHA/EPA ratio 1.81 ± 0.01. The overall acceptability score obtained by the sensory evaluation of panelists was very high (8.09 ± 0.25).

Migrations and gradations : reappraising the health profile of immigrants to Canada

New immigrants to Canada typically have a more favourable health profile than the non-immigrant population. This phenomenon, known as the 'healthy immigrant effect', has been attributed to both the socioeconomic advantage (ie. educational attainment, occupational opportunity) of non-refugee immigrants and existing screening protocols that admit only the healthiest of persons to Canada. It has been suggested that this health advantage diminishes as the time of residence in Canada increases, due in part to the adoption of health-risk behaviours such as alcohol and cigarette use, an increase in excess body weight, and declining rates of physical activity. However, the majority of health research concerning immigrants to Canada has been limited to cross-sectional studies (Dunn & Dyck, 2000; Newbold & Danforth, 2003), which may mask an immigrant-specific cohort effect. Furthermore, the practice of aggregating foreign-bom persons by geographical regions or treating all immigrants as a homogeneous group may also obfuscate intra-immigrant differences in health. Accordingly, this study uses the Canadian National Population Health Surveys (NPHS) and data from the United Nations Development Program (UNDP) to prospectively evaluate factors that predict health status among immigrants to Canada. Each immigrant in the NPHS was linked to the UNDP Human Development Index of their country of birth, which uses a combined measure of health, education, and per capita income of the populace. The six-year change in health function, psychological distress, and self-rated health were considered from a population health perspective (Evans, 1994), using generalized-estimating equations (GEE) to examine the compounding effect of past and recent predictors of health.

Profile Portrait of Major General Sir Isaac Brock 1769-1812

This work is a copy of a pastel oval portrait of General Brock that is supposedly the only known portrait of Brock to be done in his lifetime. The original was by William Berczy, circa 1808, and is in the possession of Captain M.H.T Mellish, a descendant of one of Brock's sisters. This portrait was completed on canvas.

Academic advising, eh : a profile of undergraduate academic advising at Ontario universities

Despite its importance to postsecondary students' success, there is little known about academic advisement in Canada. Academic advising can be a very intensive and demanding job, yet it is not well understood what duties or student populations of advising make it so. On a practical level, this study sought to learn more about academic advisement in Ontario universities and provide a general overview of who advisors are and what they do. This study also investigated academic advising duties and time allocation for these responsibilities in an attempt to relate theory to practice incorporating Vilfredo Pareto's theoretical underpinnings to confirm or negate the applicability of the Pareto Principle in relationship to time utilization by advisors. Essentially this study sought to discover which students require the greatest advisement time and effort, and how advisors could apply these findings to their work. Academic advising professionals in Ontario universities were asked to complete a researcher-designed electronic survey. Quantitative data from the responses were analyzed to describe generalized features of academic advising at Ontario universities. Discussion and implications for practice will prompt advisors and institutions using the results of this study to measure themselves against a provincial assessment. Advisors' awareness of time allocation to different student groups can help focus attention where new strategies are needed to maximize time and efforts. This study found that caseload and time spent with student populations were proportional. Regular undergraduate students accounted for the greatest amount of caseload and time followed by working with students struggling academically. This study highlights the need for further evaluation, education, and research in academic advising in Canadian higher education.

A Profile of Gamblers

This Study Presents Both a Comprehensive Survey Jof the Empirical Literature on Gambling and Our Most Recent Research Based on Data Provided by Both Loto-Quebec and Statistics Canada. in Spite of All the Excitement Surrounding the Subject, the Typical Gambler Emerges with the Relatively Boring Image of a Regular, Relatively Lower Paid Blue Or White Collar Worker, Whose Career Stalled, Who Is Relatively Older and Has More Children Than the Rest of the Population. But He Is Not Criminal and Does Not Spend Recklessly. the Game Gives Him Hope, Type of Hope That No Other Existing Spending Opportunities Can Provide. the Study Also Reveals That People Do Not Tell the Truth About Their Spendings on Games of Chance.

Harsanyi’s Social Aggregation Theorem : A Multi-Profile Approach with Variable-Population Extensions

This paper provides new versions of Harsanyi’s social aggregation theorem that are formulated in terms of prospects rather than lotteries. Strengthening an earlier result, fixed-population ex-ante utilitarianism is characterized in a multi-profile setting with fixed probabilities. In addition, we extend the social aggregation theorem to social-evaluation problems under uncertainty with a variable population and generalize our approach to uncertain alternatives, which consist of compound vectors of probability distributions and prospects.

Anonymous Single-Profile Welfarism

This note reexamines the single-profile approach to social-choice theory. If an alternative is interpreted as a social state of affairs or a history of the world, it can be argued that a multi-profile approach is inappropriate because the information profile is determined by the set of alternatives. However, single-profile approaches are criticized because of the limitations they impose on the possibility of formulating properties such as anonymity. We suggest an alternative definition of anonymity that applies in a single-profile setting and characterize anonymous single-profile welfarism under a richness assumption.

Multi-Profile Intergenerational Social Choice

Ferejohn and Page transplanted a stationarity axiom from Koopmans’ theory of impatience into Arrow’s social choice theory with an infinite horizon and showed that the Arrow axioms and stationarity lead to a dictatorship by the first generation. We prove that the negative implications of their stationarity axiom are more far-reaching: there is no Arrow social welfare function satisfying their stationarity axiom. We propose a more suitable stationarity axiom, and show that an Arrow social welfare function satisfies this modified version if and only if it is a lexicographic dictatorship where the generations are taken into consideration in chronological order.

Evaluation of oxytocin pharmacokinetic : pharmacodynamic profile and establishment of its cardiomyogenic potential in swine

La thérapie cellulaire est une avenue pleine de promesses pour la régénération myocardique, par le remplacement du tissu nécrosé, ou en prévenant l'apoptose du myocarde survivant, ou encore par l'amélioration de la néovascularisation. Les cellules souches de la moelle osseuse (CSMO) expriment des marqueurs cardiaques in vitro quand elles sont exposées à des inducteurs. Pour cette raison, elles ont été utilisées dans la thérapie cellulaire de l'infarctus au myocarde dans des études pre-cliniques et cliniques. Récemment, il a été soulevé de possibles effets bénéfiques de l'ocytocine (OT) lors d’infarctus. Ainsi, l’OT est un inducteur de différenciation cardiaque des cellules souches embryonnaires, et cette différenciation est véhiculée par la voie de signalisation du monoxyde d’azote (NO)-guanylyl cyclase soluble. Toutefois, des données pharmacocinétiques de l’OT lui attribue un profil non linéaire et celui-ci pourrait expliquer les effets pharmacodynamiques controversés, rapportés dans la lttérature. Les objectifs de ce programme doctoral étaient les suivants : 1) Caractériser le profil pharmacocinétique de différents schémas posologiques d'OT chez le porc, en développant une modélisation pharmacocinétique / pharmacodynamique plus adaptée à intégrer les effets biologiques (rénaux, cardiovasculaires) observés. 2) Isoler, différencier et trouver le temps optimal d’induction de la différenciation pour les CSMO porcines (CSMOp), sur la base de l'expression des facteurs de transcription et des protéines structurales cardiaques retrouvées aux différents passages. 3) Induire et quantifier la différenciation cardiaque par l’OT sur les CSMOp. 4) Vérifier le rôle du NO dans cette différenciation cardiaque sur les CSMOp. Nous avons constaté que le profil pharmacocinétique de l’OT est mieux expliqué par le modèle connu comme target-mediated drug disposition (TMDD), parce que la durée du séjour de l’OT dans l’organisme dépend de sa capacité de liaison à son récepteur, ainsi que de son élimination (métabolisme). D'ailleurs, nous avons constaté que la différenciation cardiomyogénique des CSMOp médiée par l’OT devrait être induite pendant les premiers passages, parce que le nombre de passages modifie le profile phénotypique des CSMOp, ainsi que leur potentiel de différenciation. Nous avons observé que l’OT est un inducteur de la différenciation cardiomyogénique des CSMOp, parce que les cellules induites par l’OT expriment des marqueurs cardiaques, et l'expression de protéines cardiaques spécifiques a été plus abondante dans les cellules traitées à l’OT en comparaison aux cellules traitées avec la 5-azacytidine, qui a été largement utilisée comme inducteur de différenciation cardiaque des cellules souches adultes. Aussi, l’OT a causé la prolifération des CMSOp. Finalement, nous avons observé que l'inhibition de la voie de signalisation du NO affecte de manière significative l'expression des protéines cardiaques spécifiques. En conclusion, ces études précisent un potentiel certain de l’OT dans le cadre de la thérapie cellulaire cardiomyogénique à base de cellules souches adultes, mais soulignent que son utilisation requerra de la prudence et un approfondissement des connaissances.
