Students who self-harm: coping style, rumination and alexithymia

Counsellors working with students or other young adults may encounter individuals who have self-harmed, either with suicidal or non-suicidal intent. Recent US studies reported rates of self-injury of up to 37% of the student population, but studies in the UK have focussed primarily on younger adolescents. This study examined reported self-harm incidents (scratching, cutting, poisoning, overdose etc) from a sample of 617 university students. A total of 27% reported at least one incident of self-harm, with almost 10% having harmed themselves while at university. Gender differences were not significant but psychology students reported significantly more self-harm than other students. Participants reporting self-harm scored significantly higher on maladaptive coping styles, rumination, and alexithymia (specifically difficulty in identifying emotions) and these differences were most marked for students reporting repetitive and recent self-harm. Rumination and Alexithymia factor 1 (difficulty identifying feelings) emerged as the most robust factors predicting self-harm status. Comments from students who self-harmed at university highlighted the importance of accessible services and academic staff support. The implications of these findings for counselling interventions are discussed, including challenging negative rumination tendencies and developing mindfulness skills.

Electrochemical immunosensor for multiplexed detection of food-borne pathogens using nanocrystal bioconjugates and MWCNT screen-printed electrode

Bacterial food poisoning is an ever-present threat that can be prevented with proper care and handling of food products. A disposable electrochemical immunosensor for the simultaneous measurements of common food pathogenic bacteria namely Escherichia coli O157:H7 (E. coli), campylobacter and salmonella were developed. The immunosensor was fabricated by immobilizing the mixture of anti-E. coli, anticampylobacter and anti-salmonella antibodies with a ratio of 1:1:1 on the surface of the multiwall carbon nanotube-polyallylamine modified screen printed electrode (MWCNT-PAH/SPE). Bacteria suspension became attached to the immobilized antibodies when the immunosensor was incubated in liquid samples. The sandwich immunoassay was performed with three antibodies conjugated with specific nanocrystal ( -E. coli-CdS, -campylobacter-PbS and -salmonella-CuS) which has releasable metal ions for electrochemical measurements. The square wave anodic stripping voltammetry (SWASV) was employed to measure released metal ions from bound antibody nanocrystal conjugates. The calibration curves for three selected bacteria were found in the range of 1 × 103 – 5 × 105 cells mL−1 with the limit of detection (LOD) 400 cells mL−1 for salmonella, 400 cells mL−1 for campylobacter and 800 cells mL−1 for E. coli. The precision and sensitivity of this method show the feasibility of multiplexed determination of bacteria in milk samples.

A Veterinária, os Medicamentos e a Formação dos Profissionais de Farmácia

É cada vez mais proeminente abordarmos a temática da medicina veterinária devido à necessidade de formação dos profissionais e dos cuidados requeridos nas vertentes homem/animal/ambiente. Com o principal objetivo de conhecer se a base de formação dos profissionais de farmácia é suficiente e tem resultados na satisfação das necessidades de todos os utentes com animais, foi levantado um estudo de artigos já publicados sobre o tema e posteriormente um questionário online para possível comparação dos resultados com a realidade. Abordam-se temas como: intoxicações em animais, regulamentação sobre este tipo de medicamentos, aconselhamento e consumo de medicamentos veterinários, saúde pública, algumas terapias complementares e finalmente a formação dos profissionais de farmácia. Os resultados obtidos a nível da formação destes profissionais não foram os mais satisfatórios, embora este resultado no futuro possa ser melhorado visto que há interesse por parte dos inquiridos em obter formação sobre a área. Aplicou-se um estudo observacional, do tipo transversal e analítico. A população alvo são os profissionais de farmácia portugueses. Para a recolha destas informações foi utilizado um questionário online, anónimo, confidencial e voluntário a 400profissionais. A amostra é constituída maioritariamente por indivíduos do género feminino (75%), sendo a faixa etária mais frequente dos 23 aos 25 anos (41%). Verificou-se que mais de 70% dos profissionais trabalham num local onde se vendem medicamentos veterinários e embora apenas 21% tenha tido uma formação na área. É de notar que 69% sentiu dificuldades no preenchimento do questionário e 94% considera importante obter uma formação extra nesta área, principalmente em temáticas como medicação, prevenção de doenças e alimentação.

Argyria. Case Report

A 70-year-old male rural worker was referred to our clinic with widespread grey pigmentation of the skin and nails. The condition had been asymptomatic for its entire duration (5 years). He reported past intranasal application of 10% Silver Vitellinate. A skin biopsy was performed and histology corroborated the clinical diagnosis of Argyria. This case represents a currently rare dermatological curiosity. Although silver colloids and salts have been withdrawn and/or banned by some drug surveillance agencies, they continue to be freely sold and unregulated as food supplements and as ingredients in alternative medicines, thereby risking the emergence of new cases of silver poisoning.

O contrato de Project Finance

Currently, Angola portrays a notorious economic growth and due to recent innovative legislations, it has become the major investment attracting pole, especially in Sub-Saharan Africa, having, thus, an extraordinary potentiality for a rapid and sustainable development, likely to place her in outstanding positions in the world economic ranking. Yet, such economic growth entails demanding levels of intensive investment in infrastructure, what has been reported of the Angolan Government to be unable to respond to, save if recurring to very high index of external debt, poisoning, in this way, the future budgeting of the country. Due to these infrastructure investment shortages, the cost of production remains highly onerous and the cost of life extremely unaffordable. On this account, the current study disserts about the contract of Project Finance; an alternative finance resource given as a viable solution for the private financing of infrastructure, aiming to demonstrate that such contractual figure, likewise the experience of several emerging economies and others, is a contract bid framework to take into account in today’s world. It refers to a financing technique – through which the Government may satisfy a common need (for example, the construction of a public domain or public servicing), without having to pay neither offer any collateral – based on a complex legal-financial engineering, arranged throughout a coalition of typical and atypical agreements, whereby it is mandatory to look back at the basic concepts of corporate law. More than just a simple financial study, the dissertation at stake analyses the nature and legal framework of Project Finance, which is a legally atypical and innominate contract, concluding that there is a relevant need for regulating and devoting a special legal regime in the Angolan jurisdiction for this promising legal form in the contemporary corporate finance world.

Social venture move

This study has the purpose of presenting the path of a social microcredit start-up in Mozambique. Its members had just gotten out of college and decided to put in practice what they had learnt. Even though the whole foundation of the project was developed in Mozambique, the team has extended its experience to other countries: São Tomé and Timor. However, the focus of this study will be solely in the Ilha de Mozambique’s project and the difficulties that it is facing right now, in order to try to find answers that would allow the project entrepreneurs to overcome what is keeping them from having a more successful return rate. The main issue of the project and the worse and unexpected default rate is within the fishing sector. This is peculiar, since the mission is in an island where there are plenty of fish and shellfish. By addressing this problem, and presenting the whole structure of the venture, it is its goal to understand better ways to deal with the difficulties. Its format will be as a case study and it will present as well the macroeconomics of Mozambique to justify the choice of the place, align with the team itself, and why it is possible to have a successful project with as many contacts and sponsors as this one does.

Glucosamine resistance in the yeast, Saccharomyces cerivisae [sic]

By using glucosamine resistant mutants of Saccharomyces ceriv~sa~ an attempt was made to discover the mechanisms which cause glucose repression and/or the Crabtree effect. The strains used are 4B2, GR6, lOP3r, GR8l and GRI08. 4B2 is a wild type yeast while the others are its mutants. To characterize the biochemical reactions which made these mutants resistant to glucosamine poisoning the following experiments were done~ 1. growth and respiration; 2. transport of sugars; 3. effect of inorganic phosphate (Pi): 4. Hexokinase; 5. In yivo phosphorylation. From the above experiments the following conclusions may be drawn: (i) GR6 and lOP3r have normal respiratory and fermentative pathways. These mutants are resistant to glucosamine poisoning due to a slow rate of sugar transport which is due to change in the cell membrane. (ii) GR8l has a normal respiratory pathway. The slow growth on fermentable carbon sourCEE indicates that in GR8l the lesion is in or associated with the glycolytic pathway. The lower rate of sugar transport may be due to a change in energy metabolism. The invivo phosphorylation rate indicates that in GR81 facilitated diffusion is the dominant transport mechanism. (iii) GR108 msa normal glycolytic pathway but the respiratory pathway is abnormal. The slow rate of sugar transport is due to a change in energy metabolism. The lower percentage of in vivo phosphorylation is probably due to a lowered availability of ATP because of the mitochondrial lesion. In all mutants resistance to glucosamine poisoning is due to a lower rate of utilization of ATP. which is caused by various mechanisms (see above), making less ADP available for phosphorylation via ATP synthase which utilizes inorganic phosphate. Because of the lower utilization of Pi, the concentration of intra-mitochondrial Pi does not go down thus protecting mutants from glucosamine poisoning.

Bcl-xL regulation and function in cell cycle checkpoints and progression

Quelques évidences suggèrent que Bcl-xL, un membre anti-apoptotique de la famille Bcl-2, possède également des fonctions au niveau du cycle cellulaire et de ses points-contrôle. Pour étudier la régulation et fonction de Bcl-xL au cours du cycle cellulaire, nous avons généré et exprimé dans des cellules humaines une série de mutants de phosphorylation incluant Thr41Ala, Ser43Ala, Thr47Ala, Ser49Ala, Ser56Ala, Ser62Ala et Thr115Ala. L'analyse de cette série de mutants révèle que les cellules exprimant Bcl-xL(Ser62Ala) sont moins stables au point-contrôle G2 du cycle cellulaire comparées aux cellules exprimant le type sauvage ou les autres mutants de phosphorylation incluant Thr41Ala, Ser43Ala, Thr47Ala, Ser56Ala et Thr115Ala. Les études de cinétiques de phosphorylation et de localisation de phospho-Bcl-xL(Ser62) dans des cellules synchronisées et suite à l'activation du point-contrôle en G2 médié par l'étoposide (VP16), nous indiquent que phospho-Bcl-xL(Ser62) migre dans les corps nucléolaires durant l'arrêt en G2 dans les cellules exposées au VP16. Une série d'expériences incluant des essais kinase in vitro, l'utilisation d'inhibiteurs pharmacologiques et d'ARN interférant, nous révèlent que Polo kinase 1 (PLK1) et MAPK9/JNK2 sont les protéines kinase impliquées dans la phosphorylation de Bcl-xL(Ser62), et pour son accumulation dans les corps nucléolaires pendant le point-contrôle en G2. Nos résultats indiquent que durant le point-contrôle en G2, phospho-Bcl-xL(Ser62) se lie et se co-localise avec CDK1(CDC2), le complexe cycline-kinase qui contrôle l'entrée en mitose. Nos résultats suggèrent que dans les corps nucléolaires, phospho-Bcl-xL(Ser62) stabilise l'arrêt en G2 en séquestrant CDK1(CDC2) pour retarder l'entrée en mitose. Ces résultats soulignent également que les dommages à l'ADN influencent la composition des corps nucléolaires, structure nucléaire qui émerge maintenant comme une composante importante de la réponse aux dommages à l'ADN. Dans une deuxième étude, nous décrivons que les cellules exprimant le mutant de phosphorylation Bcl-xL(Ser62Ala) sont également plus stables au point-contrôle de l'assemblage du fuseau de la chromatine (SAC) suite à une exposition au taxol, comparées aux cellules exprimant le type sauvage ou d'autres mutants de phosphorylation de Bcl-xL, incluant Thr41Ala, Ser43Ala, Thr47Ala, Ser56Ala. Cet effet est indépendent de la fonction anti-apoptotique de Bcl-xL. Bcl-xL(Ser62) est fortement phosphorylé par PLK1 et MAPK14/SAPKp38α à la prométaphase, la métaphase et à la frontière de l'anaphase, et déphosphorylé à la télophase et la cytokinèse. Phospho-Bcl-xL(Ser62) se trouve dans les centrosomes avec γ-tubuline, le long du fuseau mitotique avec la protéine moteure dynéine et dans le cytosol mitotique avec des composantes du SAC. Dans des cellules exposées au taxol, phospho-Bcl-xL(Ser62) se lie au complexe inhibiteur CDC20/MAD2/BUBR1/BUB3, alors que le mutant Bcl-xL(Ser62Ala) ne se lie pas à ce complexe. Ces résultats indiquent que durant le SAC, la phosphorylation de Bcl-xL(Ser62) accélère la résolution du SAC et l'entrée des cellules en anaphase. Des expériences bloquant l'expression de Bcl-xL révèlent ègalement un taux très élevé de cellules tétraploïdes et binuclées après un traitement au nocodazole, consistant avec une fonction de Bcl-xL durant la mitose et dans la stabilité génomique. Dans la troisième étude, l'analyse fonctionnelle de cette série de mutants de phosphorylation indique également que les cellules exprimant Bcl-xL(Ser49Ala) sont moins stables durant le point-contrôle G2 et entre en cytokinèse plus lentement dans des cellules exposées aux inhibiteurs de la polymérisation/dépolymérisation des tubulines, composantes des microtubules. Ces effets de Bcl-xL(Ser49Ala) sont indépendents de sa fonction anti-apoptotique. La phosphorylation de Bcl-xL(Ser49) est dynamique au cours du cycle cellulaire. Dans des cellules synchronisées, Bcl-xL(Ser49) est phosphorylé en phase S et G2, déphosphorylé à la prométaphase, la métaphase et à la frontière de l'anaphase, et re-phosphorylé durant la télophase et la cytokinèse. Au cours du point-contrôle G2 induit par les dommages à l'ADN, un pool important de phospho-Bcl-xL(Ser49) se trouve aux centrosomes, un site important pour la régulation de l'entrée en mitose. Durant la télophase et la cytokinèse, phospho-Bcl-xL(Ser49) se trouve le long des microtubules avec la protéine moteure dynéine et dans le cytosol mitotique. Finalement, nos résultats suggèrent que PLK3 est responsable de la phosphorylation de Bcl-xL(Ser49), une protéine kinase impliquée pour l'entrée des cellules en mitose et pour la progression de la mitose jusqu'à la division cellulaire.

Les liens entre le statut parental et les infanticides des enfants de douze ans et moins

Mondialement, l’infanticide est une cause importante de mortalité infantile. Dans ce mémoire, les infanticides sont analysés en fonction du statut parental, du mode de décès et de l’âge de l’enfant. La première hypothèse de ce mémoire propose qu’il y ait une surreprésentation des parents non biologiques dans les cas d’infanticides chez les enfants de moins de douze ans, et ce, en regard des taux de base de la population. L’hypothèse 2 prédit que les infanticides des parents biologiques devraient revêtir un caractère plus létal (utilisation d’arme à feu, empoisonnement, etc.) que ceux des parents non biologiques qui devraient être caractérisés principalement par des mauvais traitements et de la négligence. D’autres hypothèses sont examinées en fonction des taux de suicide et du sexe de l’agresseur. La présente étude porte sur les cas d’infanticides d’enfants de douze ans et moins sur le territoire du Québec provenant des archives du bureau du coroner pour la période se situant entre 1990 et 2007 (n=182). Les résultats obtenus appuient partiellement l’hypothèse 1 et confirment l’hypothèse 2. En ce sens, les résultats de cette étude viennent appuyer les hypothèses évolutionnistes qui soutiennent une influence du statut parental sur le comportement de l’infanticide. De façon générale, ces résultats mettent en lumière les différences qualitatives qui existent entre les parents biologiques et les parents non biologiques dans les cas d’infanticides. Les implications des résultats obtenus sont discutées.

Detection and quantification of staphylococcus aureus enterotoxin B in food product using isotopic dilution techniques and mass spectrometry

L’entérotoxine B staphylococcique (SEB) est une toxine entérique hautement résistante à la chaleur et est responsable de plus de 50 % des cas d’intoxication d’origine alimentaire par une entérotoxine. L’objectif principal de ce projet de maîtrise est de développer et valider une méthode basée sur des nouvelles stratégies analytiques permettant la détection et la quantification de SEB dans les matrices alimentaires. Une carte de peptides tryptiques a été produite et 3 peptides tryptiques spécifiques ont été sélectionnés pour servir de peptides témoins à partir des 9 fragments protéolytiques identifiés (couverture de 35 % de la séquence). L’anhydride acétique et la forme deutérée furent utilisés afin de synthétiser des peptides standards marqués avec un isotope léger et lourd. La combinaison de mélanges des deux isotopes à des concentrations molaires différentes fut utilisée afin d’établir la linéarité et les résultats ont démontré que les mesures faites par dilution isotopique combinée au CL-SM/SM respectaient les critères généralement reconnus d’épreuves biologiques avec des valeurs de pente près de 1, des valeurs de R2 supérieure à 0,98 et des coefficients de variation (CV%) inférieurs à 8 %. La précision et l’exactitude de la méthode ont été évaluées à l’aide d’échantillons d’homogénat de viande de poulet dans lesquels SEB a été introduite. SEB a été enrichie à 0,2, 1 et 2 pmol/g. Les résultats analytiques révèlent que la méthode procure une plage d’exactitude de 84,9 à 91,1 %. Dans l’ensemble, les résultats présentés dans ce mémoire démontrent que les méthodes protéomiques peuvent être utilisées efficacement pour détecter et quantifier SEB dans les matrices alimentaires.
