Neurobiological Correlates of Personality Traits: A Study on Harm Avoidance and Neuroticism

Harm Avoidance and Neuroticism are traits that predispose to mental illnesses. Studying them provides a unique way to study predisposition of mental illnesses. Understanding the biological mechanisms that mediate vulnerability could lead to improvement in treatment and ultimately to pre-emptive psychiatry. These personality traits describe a tendency to feel negative emotions such as fear, shyness and worry. Previous studies suggest these traits are regulated by serotonin and opiate pathways. The aim of this thesis was to test the following hypotheses using personality trait measures and positron emission tomography (PET): 1) Brain serotonin transporter density in vivo is associated with Harm Avoidance and Neuroticism traits. 2) μ-opioid receptor binding is associated with Harm Avoidance. In addition, we developed a methodology for studying neurotransmitter interactions in the brain using the opiate and serotonin pathways. 32 healthy subjects who were consistently in either the highest or lowest quartile of the Harm Avoidance trait were recruited from a population-based cohort. Each subject underwent two PET scans, serotonin transporter binding was measured with [11C] MADAM and μ-opioid receptor binding with [11C]carfentanil. We found that the serotonin transporter is not associated with anxious personality traits. However, Harm Avoidance positively correlated with μ-opioid receptor availability. Particularly the tendency to feel shy and the inability to cope with stress were associated μ-opioid receptor availability. We also demonstrated that serotonin transporter binding correlates with μ-opioid receptor binding, suggesting interplay between the two systems. These findings shed light on the neurobiological correlates of personality and have an impact on etiological considerations of affective disorders.

Carnaval da Nova Consciência

Um evento que promove o contato inter-religioso, ao mesmo tempo em que divulga uma "leitura" de realidades com conotação terapêutica. Propõe o diálogo de práticas religiosas com temas de amplo interesse na atualidade, tais como tolerância, paz, diversidade, questões ambientais, entre outros. Um espaço aberto que incorpora a cada edição novos diálogos, o que contribui para sua permanência. O texto sublinha interações e diálogos entre atores no ENC, por meio de referências associadas à religiosidade, enquanto vivência e partilha, num horizonte de produção e difusão de práticas e conteúdos que ganham expressividade pelo reconhecimento coletivo.

Dos igarapés da Amazônia para o outro lado do Atlântico: a expansão e internacionalização do Santo Daime no contexto religioso global

Este artigo analisa os processos de expansão da religião ayahuasqueira do Santo Daime da Amazônia para o mundo. O crescimento e internacionalização daimistas são explicados em função de suas características estruturais, a psicoatividade e miscibilidade. Essa expansão é contextualizada dentro do movimento diaspórico das religiões do sul global, isto é, responde ao crescente papel do Brasil e da América Latina no cenário religioso global contemporâneo. Tal crescimento, contudo, foi conflituoso e permeado de tensões nos vários locais em que ocorreu. A expansão também produziu varias consequências nas comunidades tradicionais amazônicas. Argumenta-se que a internacionalização do Santo Daime ilustra as controvérsias e ambivalências religiosas de nosso tempo, estimulando o debate sobre questões fundamentais relacionadas ao contexto religioso global e à própria modernidade.

Missão Midiática afrikania: representando a “religião tradicional afrikana” na esfera pública cristã em Gana

No campo de estudos de religião e mídia, a importância da comunicação de massa está bem estabelecida para as religiões globalizadas tais como o cristianismo e o islamismo, mas o mesmo não se verifica com relação às religiões nativas africanas. O presente artigo busca preencher essa lacuna investigando as atividades de mídia de um movimento religioso neo-tradicional em Gana, a Missão Afrikania. Ao analisar a posição cambiante de Afrikania na esfera pública em relação a mudanças nos cenários político, religioso e midiático de Gana, demonstro como novos constrangimentos e oportunidades levaram Afrikania a adaptar suas estratégias de acesso à mídia e seus estilos de representação. A política de representação da Afrikania é complexificada pela sua posição delicada entre uma esfera pública de hegemonia cristã e as práticas dos sacerdotes e sacerdotisas que ela visa representar.

Ultrastructural study of the neovagina following the utilization of human amniotic membrane for treatment of congenital absence of the vagina

We present an ultrastructural study of the utilization of human amniotic membrane in the treatment of congenital absence of the vagina in 10 patients. All patients were surgically treated with application of an amniotic membrane graft using the modified McIndoe and Bannister technique. Sixty days after surgery, samples of the vaginal neo-epithelium were collected for transmission electron microscopy analysis. The ultrastructural findings consisted of a lining of mature squamous epithelium indicating the occurrence of metaplasia of the amniotic epithelium into the vaginal epithelium. The cells were arranged in layers as in the normal vaginal epithelium, i.e., superficial, intermediate and deep layers. There were desmosomes and cytoplasmic intermediate cytokeratin filaments, as well as some remnant features of the previous amniotic epithelium. These findings suggest that human amniotic membrane is able to complete metaplasia into squamous cells but the mechanism of this cellular transformation is unknown

Abnormal proliferative response of the carotid artery of spontaneously hypertensive rats after angioplasty may be related to the depolarized state of its smooth muscle cells

Hypertension is one of the major precursors of atherosclerotic vascular disease, and vascular smooth muscle abnormal cell replication is a key feature of plaque formation. The present study was conducted to examine the relationship between hypertension and smooth muscle cell proliferation after balloon injury and to correlate neointima formation with resting membrane potential of uninjured smooth muscle cells, since it has been suggested that altered vascular function in hypertension may be related to the resetting of the resting membrane potential in spontaneously hypertensive rats (SHR). Neointima formation was induced by balloon injury to the carotid arteries of SHR and renovascular hypertensive rats (1K-1C), as well as in their normotensive controls, i.e., Wistar Kyoto (WKY) and normal Wistar (NWR) rats. After 14 days the animals were killed and the carotid arteries were submitted to histomorphometric and immunohistochemical analyses. Resting membrane potential measurements showed that uninjured carotid arteries from SHR smooth muscle cells were significantly depolarized (-46.5 ± 1.9 mV) compared to NWR (-69 ± 1.4 mV), NWR 1K-1C (-60.8 ± 1.6 mV), WKY (-67.1 ± 3.2 mV) and WKY 1K-1C (-56.9 ± 1.2 mV). The SHR arteries responded to balloon injury with an enhanced neointima formation (neo/media = 3.97 ± 0.86) when compared to arteries of all the other groups (NWR 0.93 ± 0.65, NWR 1K-1C 1.24 ± 0.45, WKY 1.22 ± 0.32, WKY 1K-1C 1.15 ± 0.74). Our results indicate that the increased fibroproliferative response observed in SHR is not related to the hypertensive state but could be associated with the resetting of the carotid smooth muscle cell resting membrane potential to a more depolarized state.

Potential for synthetic gas in Finnish industry

Finland, other Nordic countries and European Union aim to decarbonize their energy production by 2050. Decarbonization requires large scale implementation of non-emission energy sources, i.e. renewable energy and nuclear power. Stochastic renewable energy sources present a challenge to balance the supply and demand for energy. Energy storages, non-emissions fuels in mobility and industrial processes are required whenever electrification is not possible. Neo-Carbon project studies the decarbonizing the energy production and the role of synthetic gas in it. This thesis studies the industrial processes in steel production, oil refining, cement manufacturing and glass manufacturing, where natural gas is already used or fuel switch to SNG is possible. The technical potential for fuel switching is assessed, and economic potential is necessary after this. All studied processes have potential for fuel switching, but total decarbonization of steel production, oil refining requires implementation of other zero-emission technologies.

Correlation between total nitrite/nitrate concentrations and monoamine oxidase (types A and B) and semicarbazide-sensitive amine oxidase enzymatic activities in human mesenteric arteries from non-diabetic and type 2 diabetic patients

The aim of this study was to determine the correlation between total nitrite/nitrate concentrations (NOx) and the kinetic parameters of monoamine oxidase enzymes (MAO-A and MAO-B) and semicarbazide-sensitive amine oxidase (SSAO) in human mesenteric arteries. Arteries were from non-diabetic and type 2 diabetic patients with sigmoid or rectum carcinoma for whom surgery was the first option and who were not exposed to neo-adjuvant therapy. Segments of human inferior mesenteric arteries from non-diabetic (61.1 ± 8.9 years old, 7 males and 5 females, N = 12) and type 2 diabetic patients (65.8 ± 6.2 years old, 8 males and 4 females, N = 12) were used to determine NOx concentrations and the kinetic parameters of MAO-A, MAO-B and SSAO by the Griess reaction and by radiochemical assay, respectively. The NOx concentrations in arteries from diabetic patients did not differ significantly from those of the non-diabetic group (10.28 ± 4.61 vs 10.71 ± 4.32 nmol/mg protein, respectively). In the non-diabetic group, there was a positive correlation between NOx concentrations and MAO-B parameters: Km (r = 0.612, P = 0.034) and Vmax (r = 0.593, P = 0.042), and a negative correlation with the SSAO parameters: Km (r = -0.625, P = 0.029) and Vmax (r = -0.754, P = 0.005). However, in the diabetic group no correlation was found between NOx concentrations and the three kinetic parameters of the enzymes. These results suggest an important function of sympathetic nerves and vascular NOx concentrations in arteries of non-diabetic patients. Thus, these results confirm the importance of a balance between oxidants and antioxidants in the maintenance of vascular homeostasis to prevent oxidative stress.

Economics of Power-to-Gas integration to wastewater treatment plant

Solar and wind power produce electricity irregularly. This irregular power production is problematic and therefore production can exceed the need. Thus sufficient energy storage solutions are needed. Currently there are some storages, such as flywheel, but they are quite short-term. Power-to-Gas (P2G) offers a solution to store energy as a synthetic natural gas. It also improves nation’s energy self-sufficiency. Power-to-Gas can be integrated to an industrial or a municipal facility to reduce production costs. In this master’s thesis the integration of Power-to-Gas technologies to wastewater treatment as a part of the VTT’s Neo-Carbon Energy project is studied. Power-to-Gas produces synthetic methane (SNG) from water and carbon dioxide with electricity. This SNG can be considered as stored energy. Basic wastewater treatment technologies and the production of biogas in the treatment plant are studied. The utilisation of biogas and SNG in heat and power production and in transportation is also studied. The integration of the P2G to wastewater treatment plant (WWTP) is examined mainly from economic view. First the mass flows of flowing materials are calculated and after that the economic impact based on the mass flows. The economic efficiency is evaluated with Net Present Value method. In this thesis it is also studied the overall profitability of the integration and the key economic factors.

The political role of the State in Cambridge theories of growth and distribution

In this paper we extend Kaldor’s Neo-Pasinetti theorem to the scope of budgetary interventions based on political orientations. First, we take into account a system of taxes and expenditures. Second, we introduce different reaction functions for public spending showing the political role of the State in Cambridge theory of distribution. It turns out that the validity of Kaldorian results depends on the political orientation adopted by government, which diminishes the range of application of the Neo-Pasinetti theorem.

Para superar el estancamiento económico en México: "nudos críticos" de un proyecto nacional de desarrollo

This article is devoted to analyze changes in economic policy to be adopted by Mexico if a national development project were implemented. Starting from an evaluation of the main economic and political outcomes of Vicente’s Fox administration, the author proposes an alternative development strategy which permits Mexico to overcome economic stagnation. That strategy would be based in recovering the internal market as the dynamical focus of the economy with the purpose of satisfying basic needs of people. To be successful this strategy should to confront the "critical knots" of the Neo-liberal model: to reverse the uneven distribution of income; abandoning the fixing of restrictive monetary, fiscal and exchange rate policies; and mobilizing economic surplus by means of a profound revision of debt service schemes. It concludes that to implement a national development project it is required a political and economic strategy to dismantle neoliberalism, which is an antinational structure of power.

Rethinking the economics of capital mobility and capital controls

This paper reexamines the issue of international financial capital mobility, which is today's economic orthodoxy. Discussion is often framed in terms of the impossible trinity. That framing distorts discussion by representing capital mobility as having equal significance with sovereign monetary policy and control over exchange rates. It also distorts discussion by ignoring possibilities for coordinated monetary policy and exchange rates, and for managed capital flows. The case for capital mobility rests on neo-classical economic efficiency arguments and neo-liberal political arguments. The case against capital mobility is based on Keynesian macroeconomic inefficiency arguments, neo-Walrasian market failure arguments, and neo-Marxian arguments regarding distortion of the social structure of accumulation. Close examination shows the case for capital mobility to be extremely flimsy, pointing to the ideological dimension behind today's policy orthodoxy.

Da economia política à política econômica: o novo-desenvolvimentismo e o governo Lula

From political economy to economic policy: The neo-developmentalism and the Lula administration. This article critically reviews the design of neo-developmentalist economic policies in Brazil, in the first half of the last decade, and their relationship with the economic policies of the Lula administration after 2006. Paradoxically, the neo-developmentalist policies were implemented jointly with the main (neoliberal) macroeconomic policies which had been introduced earlier. The article reviews the relevant literature, and examines the contradictory nature of this 'inflection' of economic policy. So far, this combination of policies has achieved an unquestionable - though provisional - success, despite the persistence of the structural macroeconomic problems due to the continuity of the neoliberal policies.

Brasil (1955-2005): 25 anos de catching up, 25 anos de falling behind

Brazil (1955-2005): 25 years of catching-up, 25 years of falling behind. The present paper discusses the Brazilian industrial development under a neo-schumpeterian perspective in the period after 1955. The hypothesis is that, in the last 50 years, Brazil spent the first 25 years catching up and, next, the following 25 years falling behind. The 1955-1980 period, by means of international funding, allowed catching up with the paradigm in maturation within the fourth technological revolution. However, in this period, it was determined the main debilitating elements for the country's entrance in the new techno-economical paradigm of the fifth technological revolution which emerged in the middle of the 70s. It is in the strategy to internationalize the economy, granting the mutinational companies the key-sectors of the national economy dynamics during the catching up period, the main element of dependence in the journey that conditions the current performance, responsible for technology subordination and keeps the Brazilian economy with low dynamism.
