The Influence of Estrogens on the Biological and Therapeutic Actions of Growth Hormone in the Liver

[EN]GH is main regulator of body growth and composition, somatic development, intermediate metabolism and gender-dependent dimorphism in mammals. The liver is a direct target of estrogens because it expresses estrogen receptors which are connected with development, lipid metabolism and insulin sensitivity, hepatic carcinogenesis, protection from drug-induced toxicity and fertility. In addition, estrogens can modulate GH actions in liver by acting centrally, regulating pituitary GH secretion, and, peripherally, by modulating GHR-JAK2-STAT5 signalling pathway

Deleterious Effects of Lard-enriched Diet on Tissues Fatty Acids Composition and Hypothalamic Insulin Actions

Altered tissue fatty acid (FA) composition may affect mechanisms involved in the control of energy homeostasis, including central insulin actions. In rats fed either standard chow or a lard-enriched chow (high in saturated/low in polyunsaturated FA, HS-LP) for eight weeks, we examined the FA composition of blood, hypothalamus, liver, and retroperitoneal, epididymal and mesenteric adipose tissues. Insulin-induced hypophagia and hypothalamic signaling were evaluated after intracerebroventricular insulin injection. HS-LP feeding increased saturated FA content in adipose tissues and serum while it decreased polyunsaturated FA content of adipose tissues, serum, and liver. Hypothalamic C20:5n-3 and C20:3n-6 contents increased while monounsaturated FA content decreased. HS-LP rats showed hyperglycemia, impaired insulin-induced hypophagia and hypothalamic insulin signaling. The results showed that, upon HS-LP feeding, peripheral tissues underwent potentially deleterious alterations in their FA composition, whist the hypothalamus was relatively preserved. However, hypothalamic insulin signaling and hypophagia were drastically impaired. These findings suggest that impairment of hypothalamic insulin actions by HS-LP feeding was not related to tissue FA composition.

The ‘peaks and troughs’ of societal violence: Revisiting the actions of Turkish and Kurdish shopkeepers during the 2011 London riots

This article examines an instance of contained violence during the 2011 riots in London, when Turkish and Kurdish ‘shopkeepers’ in Dalston, East London prevented rioters from entering the area. Introducing a ‘peaks’ and ‘troughs’ approach to the sociological study of violence, the article argues that we need to look at the troughs of non-violence in order to understand the peaks of violence and vice-versa. Based on a small-scale empirical study, this article also shows that contrary to the dominant representation of social actors playing fixed roles during social unrest, we found shifting positions and blurred boundaries in the drama of the 2011 riots. The paper demonstrates that the instance of contained violence in Dalston was informed by three types of reverberations. Firstly, we identified anticipatory reverberations, as the shopkeepers were aware of concurrent events elsewhere in London and, as a result, anticipated rioting in Dalston. Secondly, we saw experiential reverberations, as they used their own experience of unrest in Turkey to inform their behaviour. Finally, the representation of the action of the shopkeepers in traditional and social media may have contributed to the containment of violence elsewhere in England, suggesting representational reverberations.

Reasoning about change over time: Actions, events and their effects

This paper presents a new formalism for reasoning about change over time. The formalism derives a clean separation between the notion of states and situations. It allows more flexible temporal causal relationships than do other formalisms for reasoning about causal change, such as the situation calculus and the event calculus. It includes effects that start during, immediately after, or some time after their causes, and which end before, simultaneously with, or after their causes. A formal distinction between actions, action-types and events is proposed, which allows the expression of common-sense causal laws at high level. It is shown how these laws can be used to deduce state change over time at low level, when events occur under certain preconditions hold. Two problems that beset most interval-based temporal systems, i.e., the so-called dividing instant problem and intermingling problem, are absent from the formalism.

Le potentiel des coopératives d'épargne et de crédit comme acteur de développement local en zone urbaine ; de la planification stratégique à la pérennité des actions. Étude de cas : Querétaro, Mexique

L'Amérique latine se caractérise comme une région ayant la pire répartition de la richesse et le Mexique n'y fait pas exception. Malgré que la dernière décennie lui ait apporté la stabilisation économique et la libéralisation des échanges commerciaux, l'écart entre les riches et les pauvres continue de croître. Pour certains experts, la cause principale de cette situation réside dans les effets de la mondialisation. Bien qu'ils contribuent à déstabiliser les économies locales, d'autres éléments présents au Mexique menacent autant le développement durable des communautés mexicaines. Notons la fragilité des démocraties, la faiblesse des institutions financières, les histoires de corruption et de trafic de drogue, l'exclusion sociale et la dégradation de l'environnement. Plusieurs programmes de développement socioéconomiques ont été mis en place par différents gouvernements mexicains. Que ce soit, des programmes en matière de santé et d'éducation, des programmes alimentaires et agricoles ou de construction d'infrastructures, ils visent essentiellement à réduire la pauvreté en milieux ruraux. Les problèmes sociaux en zones urbaines ne font pas partie des priorités actuelles de l'agenda politique du gouvernement fédéral. Les communautés urbaines doivent donc se tourner vers d'autres moyens pour assurer leur développement et, la micro-finance est l'une des solutions qui a depuis longtemps fait ses preuves en matière de mobilisation des populations hasardeuses. En effet, elle permet aux populations exclues des systèmes financiers traditionnels d'avoir un plus grand contrôle de leur avenir par l'auto emploi et par le développement endogène de leur communauté. Elle introduit donc une dynamique d'autonomie et vise des changements économiques et sociaux à long terme. Par contre, une des plus grandes erreurs commises est pourtant de prétendre que la micro-finance est le remède de toutes les calamités. Les besoins des populations moins nanties en zones urbaines ne se limitent pas aux besoins de financement. Les pauvres ont également besoin de logements salubres, d'eau potable, d'électricité, de soins de santé, d'écoles et d'infrastructure, ce en quoi tout être humain est en droit de posséder. De plus, le développement durable n'est pas qu'une question de solution aux problèmes de pauvreté, il concerne également tous les citadins. Lorsque l'on parle de qualité de vie, on parle également d'emplois disponibles, de revitalisation de quartiers, d'aménagement d'espaces verts, de construction de centres sportifs et culturels, pour en nommer que quelques-uns. En l'absence de volonté ou de moyens politiques en la matière, la coopérative d'épargne et de crédit peut-elle être un levier de développement local pour une communauté urbaine mexicaine? C'est la question à laquelle je me suis attardée ces derniers mois, en analysant le contexte socio-économique de la ville de Querétaro au Mexique. Pour ce faire, j'ai exécuté d'abord une intervention dans une importante coopérative d'épargne et de crédit et je me suis ensuite documentée à travers des entrevues formelles et informelles, des observations, des conférences diverses et la littérature locale et internationale. Après avoir présenté, dans le premier chapitre, le contexte socio-politico-économique du Mexique et en particulier celui de la municipalité de Querétaro, je décris, au chapitre 2, les différents problèmes que vivent au quotidien les citadins. Le chapitre 3 est consacré à l'environnement et aux ressources qu'offrent les coopératives mexicaines d'épargne et de crédit: leur importance, les principes, la législation, les forces et les faiblesses, les menaces et les opportunités, etc. Le chapitre suivant définit le développement local en zone urbaine, ses principes, le processus qui l'accompagne, les acteurs impliqués et la finalité. Enfin le chapitre 5 nous amène au coeur même de la réflexion, c'est-à-dire évaluer si la coopérative d'épargne et de crédit possède le potentiel nécessaire pour être un acteur important de développement local en zones urbaines mexicaines.

Fundamental domains for proper affine actions of Coxeter groups in three dimensions

We study proper actions of groups $G \cong \Z/2\Z \ast \Z/2\Z \ast \Z/2\Z$ on affine space of three real dimensions. Since $G$ is nonsolvable, work of Fried and Goldman implies that it preserves a Lorentzian metric. A subgroup $\Gamma < G$ of index two acts freely, and $\R^3/\Gamma$ is a Margulis spacetime associated to a hyperbolic surface $\Sigma$. When $\Sigma$ is convex cocompact, work of Danciger, Gu{\'e}ritaud, and Kassel shows that the action of $\Gamma$ admits a polyhedral fundamental domain bounded by crooked planes. We consider under what circumstances the action of $G$ also admits a crooked fundamental domain. We show that it is possible to construct actions of $G$ that fail to admit crooked fundamental domains exactly when the extended mapping class group of $\Sigma$ fails to act transitively on the top-dimensional simplices of the arc complex of $\Sigma$. We also provide explicit descriptions of the moduli space of $G$ actions that admit crooked fundamental domains.

Management accounting and supply chains: actions, concerns, and networks

What does this thesis do? This thesis uses Actor-Network Theory (ANT) to examine how a UK retailer’s organization and strategy, and, in turn, its form of management accounting was shaped by its supply chain. The thesis does this by reporting on four related themes in the form of four inter-connected essays. The first essay undertakes a state-of-the-art review of the literature. It examines how accounting issues within supply chains permeate ‘matters of concern’. In accordance with this idea of ANT, the essay illustrates how issues emerged, controversies developed, and matters evolved through an actor-network of accounting researchers within the supply chain domain. This leads on to the second essay, which exemplifies the nature of the UK’s retailing industry within which the supply chain case organization emerged and developed. The purposes of the essay are twofold: to introduce the contextual ramifications of the case organization; and to illustrate the emergence of a new market logic, which led to the creation of a global supply chain and a new form of management accounting therein. The third essay reports on a qualitative case study. It analyses the dualistic relation between ostensive and performative aspects of supply chain strategy, reveals how accounting numbers act as an obligatory passage point within this dualism, and makes a contribution to the ANT debate around the issue of whether and how a dualism between ostensive and performative aspects exists. The final essay reports on another case analysis of institutionalizing a heterarchical form of management accounting: a distributed form of intelligence that penetrates through lateral accountable relations. The analysis reveals a new form of management accounting characterised by ambiguity; it emphasizes the possibilities of compromises and negotiations, and it thus contributes to knowledge by combining an aspect of ANT with heterarchical tendencies in the world of contemporary organizations. Finally, the thesis concludes that it is the supply chain that organises today’s neoliberal capitalism; and it is management accounting that unites both human and non-human actors within such supply chains, despite that form of management accounting being ambiguous. The thesis comprises the introduction, these four essays, and the conclusion.

An Investigation of Presumptive Synergism of Oil Palm Bunch Ash and Sawdust Amendments in Remediation of crude oil Spiked Soil

Presumed synergistic effect of combined amendment of crude oil spiked soil with oil palm bunch ash and sawdust was carried out in a laboratory experiment. Two kilogram (2 kg) of sandy soil was placed in each of five plastic vessels labeled TA, TB, TC, TD and TE. TA was left in its natural state while the others were each polluted with 6.7% v/w of crude oil. TB was not given any remediation amendment. TC and TD were each amended with 13.3% of oil palm bunch ash and sawdust respectively while TE was amended with 13.3% each of oil palm bunch ash and sawdust. The setups were replicated five times and watered twice weekly. Results showed that soil pH increased from 8.7±0.04 to 10.5±0.06, 5.3±0.01 to 8.5±0.04 and 5.6±0.18 to 11.5±0.15 for TC, TD and TE respectively. Percentage total petroleum hydrocarbon contents reduced by 65% for TC, TD and 52% for TE. Total organic carbon increased from 7.6±0.7 to 8.5±0.5%%, reduced from 4.0±0.1% to 3.7±0.3% and from 4.1±0.1% to 2.2±1.0% TC, TD and TE respectively. Total nitrogen increased from 0.66±0.1 to 0.69±0.0% for TC, remained nearly the same for TD and reduced from 0.4±0.0 to 0.2±0.0% for TE while average phosphorus increased from 0.4±0.0 to 23.0±4.2 mg/kg, 0.3±0.0 to 1.8±0.4 mg/kg and from 0.2±1.0 mg/kg to 52.6±4.6 mg/kg for TC, TD and TE respectively. Conclusively, combined amendment with oil palm bunch ash and sawdust did not induce synergism in soil total petroleum hydrocarbon content reduction.

From Hill to Harbor: Serving Water and People on Baltimore's Civic Waterfront

People and cities alike derive their life from water. Water is consequently influenced by the actions of people and cities. This crucial relationship deserves to be commemorated, and also analyzed as further human development, sea level rise, and ecological remediation efforts influence its form. This thesis seeks to remember the past condition, recognize the current, and positively influence the future of this relationship in Baltimore’s Inner Harbor through a waterfront park and harbor history museum. How can a building and a site work together to improve the health of local hydrology while still effectively serving its human community? This thesis weaves these opportunities together to create a responsible redesign of Rash Field and Federal Hill on the south side of the Inner Harbor in Baltimore.

Dentists’ actions about oral health of individuals with Down Syndrome

Aim: To investigate the knowledge and actions of dentists for treatment of individuals with Down syndrome. Methods: A questionnaire was applied to all the dentists (n=90) working at the FHS (Family Health Strategy) modules in the urban limits of Parnaíba, PI, Brazil. Four of the questions in the questionnaire were written according to the Theory of Planned Behavior Table and Likert scale (questions 6,7,9 and 15), in order to analyze the professionals’ intentions. Sixteen objective questions were elaborated with the purpose of collecting information about the degree of the dentists’ knowledge as regards the intention of attending courses in the patients with special needs area including DS, and interaction with other professionals and families. The option was to use a questionnaire applied to the dentists of the region, from August to November 2014. Results: It was found that most professionals were women and they considered themselves able to identify these patients. Among the professionals, 70% showed they had no difficulty in identifying the patient with DS, and 5.2% had no opinion about the subject. Only 6.6% of the professionals showed to be certain about their aptitude to attend to these patients; 70% were partially apt, that is, they were not absolutely sure about their aptness. There was a statistical relationship between the variables understanding and difficulty in the treatment. There was no statistical relationship between the variable capacity to identify, understanding of the needs and fitness variable in attendance. Conclusions: Patients with Down syndrome need more attention and care of dentists, they must also be involved in a multidisciplinary approach. Most of the professionals do not follow the procedures laid down by the Ministry of Health, but showed interest in attending a course in this area and there is a low number of SD patients being cared in Parnaíba, PI.
