The Building Blocks of International Ecological Footprint inequality: A Regression-Base Decomposition

This paper performs an empirical Decomposition of International Inequality in Ecological Footprint in order to quantify to what extent explanatory variables such as a country’s affluence, economic structure, demographic characteristics, climate and technology contributed to international differences in terms of natural resource consumption during the period 1993-2007. We use a Regression- Based Inequality Decomposition approach. As a result, the methodology extends qualitatively the results obtained in standard environmental impact regressions as it comprehends further social dimensions of the Sustainable Development concept, i.e. equity within generations. The results obtained point to prioritizing policies that take into account both future and present generations. Keywords: Ecological Footprint Inequality, Regression-Based Inequality Decomposition, Intragenerational equity, Sustainable development.

Allele variants in functional MicroRNA target sites of the neurotrophin-3 receptor gene (NTRK3) as susceptibility factors for anxiety disorders

Genetic and functional data indicate that variation in the expression of the neurotrophin-3 receptor gene (NTRK3) may have an impact on neuronal plasticity, suggesting a role for NTRK3 in the pathophysiology of anxiety disorders. MicroRNA (miRNA) posttranscriptional gene regulators act by base-pairing to specific sequence sites, usually at the 3'UTR of the target mRNA. Variants at these sites might result in gene expression changes contributing to disease susceptibility. We investigated genetic variation in two different isoforms of NTRK3 as candidate susceptibility factors for anxiety by resequencing their 3'UTRs in patients with panic disorder (PD), obsessive-compulsive disorder (OCD), and in controls. We have found the C allele of rs28521337, located in a functional target site for miR-485-3p in the truncated isoform of NTRK3, to be significantly associated with the hoarding phenotype of OCD. We have also identified two new rare variants in the 3'UTR of NTRK3, ss102661458 and ss102661460, each present only in one chromosome of a patient with PD. The ss102661458 variant is located in a functional target site for miR-765, and the ss102661460 in functional target sites for two miRNAs, miR-509 and miR-128, the latter being a brain-enriched miRNA involved in neuronal differentiation and synaptic processing. Interestingly, these two variants significantly alter the miRNA-mediated regulation of NTRK3, resulting in recovery of gene expression. These data implicate miRNAs as key posttranscriptional regulators of NTRK3 and provide a framework for allele-specific miRNA regulation of NTRK3 in anxiety disorders.

One case, 3 rare simultaneous findings: intramyocardial bronchogenic cyst, P.H558R variant of SCN5A gene, and granular cell tumor of the esophagus.

We describe the sudden death of a 42-year-old white man. The decedent was a healthy young man with a short clinical history of chest pain, fatigue, dizziness, and pyrosis. Two weeks before his death, he underwent medical evaluation for the aforementioned symptoms. Electrocardiogram, chest x-ray, and serum troponin were all within normal limits. Gastroesophageal reflux disease was suspected, and the decedent was treated with omeprazole. Medicolegal autopsy disclosed an incidental intramyocardial bronchogenic cyst and p.H558R variant of the SCN5A gene. The cyst was located between the epicardium and myocardium of the posterior face of the left superior ventricular wall, adjacent to the base of the heart. An incidental granular cell tumor of the esophagus was also identified, which was likely unrelated to death.

Capital cities of federations. On the way to analysing the normative base of their asymmetrical status

Federal Capitals often have special statutes. Compared with member states, they often enjoy a lower degree of self-government and a lesser share in the governing of the federation. Why do actors choose such devices, and how can they be justified in a liberal democracy? Surprisingly, the burgeoning literature on asymmetric federalism (to which our research group has contributed significantly) has overlooked this important feature of a de iure asymmetry, perhaps because political theory up to now has concentrated on cases of multicultural and plurinational federations. However, comparative literature is also rare. This paper is the first step to filling in this gap by comparing some federal capitals. The Federal District model (Washington) is compared to capitals organized as member-states (Berlin and Brussels), and capitals that are cities belonging to a single member state (Ottawa in Ontario). The different features of de iure asymmetry will thereby be highlighted. Some light will be shed on the possible motives, reasons and justifications for the choice of each respective status. The paper opens the door to further research on such status questions by analysing public and parliamentary debates, for example. It paves the way for more thorough research. Sicne the author has been awarded a grant by the Institut d’Estudis Autonòmics, this research will be carried out soon.

A Knudsen flow reactor has been used to quantify functional groups on the surface of seven different types of combustion particle samples: 3 amorphous carbons (FS 101, Printex 60, FW 2), 2 flame soots (hexane soot generated from a rich and a lean diffusion flame), and 2 Diesel particles (SRM 2975, Diesel soot recovered from a Diesel particulate filter). The technique is based on a heterogeneous titration reaction between a probe gas and a specific functional group on the particle surface. Six probe gases have been selected for the quantification of important functional groups: N(CH3)3 for the titration of acidic sites, NH2OH for carbonyl functions of aldehydes and ketones, CF3COOH and HCl for basic sites of different strength, O3 and NO2 for oxidizable groups. The limit of detection was generally well below 1% of a formal monolayer of adsorbed probe gas. Results obtained with N(CH3)3 were higher for the FW 2 amorphous carbon (post-oxidized sample, according to the manufacturer) and the Diesel particles (between 5.2·10 13 and 5.8·10 13 molecule/cm2), indicating a higher state of oxidation than for the other samples (between 1.3·10 12 and 3.7·10 12 molecule/cm2). The ratio of uptakes of CF3COOH and HCl inferred the presence of basic oxides on the particle surface, owing to the larger stability of the acetate compared to the chloride counter ion in the resulting pyrylium salt. The reactivity of the FS 101 amorphous carbon (3.7·10 15 molecule/cm2) and the hexane flame soot (between 1.9·10 15 and 2.7·10 15 molecule/cm2) towards O3 was very high, indicating the presence of a huge amount of oxidizable or reduced groups on the surface of these samples. Besides the quantification of surface functional groups, the kinetics of reactions between particles and probe gases has also been studied. The uptake coefficient γ0 was roughly correlated with the amount of probe gas taken up by the samples. Indeed, the presence of a high density of functional groups led to fast uptake of the probe gas. These different findings indicate that the particle surface appeared multi-functional, with the simultaneous presence of antagonistic functional groups which do not undergo internal chemical reactions, such as acid-base neutralization. Results also point to important differences in the surface reactivity of the samples, depending on the combustion conditions. The relative distribution of the surface functional groups may be a useful indicator for the state of oxidation and the reactivity of the particle surface.

Gamma Knife radiosurgery in benign skull base tumors after planned subtotal resection: preliminary results in combined approaches

Aim: The management of large lesions of the skull base, such as vestibular schwanommas (VS), meningiomas (MEN) or pituitary adenomas (PA), is challenging, with microsurgery remaining the main treatment option. Planned subtotal resection is now being increasingly considered to reduce the risk of neurological deficits following complete resection. The residual part of the tumor can then be treated with Gamma Knife Radiosurgery (GKR) to achieve long-term growth control. Methods: This case series documents early results with planned subtotal resection followed by GKR in Lausanne University Hospital, between July 2010 and March 2012. There were 24 patients who underwent surgery, with 22 having already undergone GKR and 2 waiting for GKR. We analyzed clinical symptoms for all patients, as well as audiograms, ophthalmological and endocrinological tests, when indicated. Results: Nine patients had VS surgery (mean diameter 35 mm; range 30-44.5) through a retrosigmoid approach. There were no post-operative facial nerve deficits. Of the 3 patients whom had useful hearing pre-operatively, this improved in 2 and remained stable in 1. Four patients with clinoid MEN (mean diameter 26.5 mm; range 17-42) underwent subtotal resection of the tumor, and the component in the cavernous sinus was later treated with GKR. The visual status remained stable in 3 patients and one had complete visual recovery. 4 patients underwent subtotal resection of petro-clival MEN (mean diameter 36 mm; range 32-42): 3 had House-Brackmann (HB) grade 2 facial function that recovered completely; one continues to have HB grade 4 facial deficit following surgery. Of the 7 patients with PA (mean diameter 34.5 mm; range 20-54.5), 2 had acromegaly, the others were non functional PA. Six patients underwent trans-sphenoidal surgery, while one patient had a transcavernous sinus resection of the tumor (with prior staged trans-sphenoidal surgery). Visual status improved in 3 patients while the others remained stable. Two patients had transient diabetes insipidus following surgery. Up to now, no additional deficit or worsening has been reported after GKR. Conclusions: Our data suggest that planned subtotal resection has an excellent clinical outcome with respect to preservation of cranial nerves, and other neurological functions, and a good possibility of recovery of many of the pre-operative cranial nerve dysfunctions. The results in terms of tumor control following GKR need further long-term evaluation.

Memoritzar avui dia a l’aula de música : nous recursos en base a la investigació contemporània de la memòria

Aquest projecte final vol ser un acostament senzill, però amb voluntat de rigorositat respecte a la capacitat mnemònica en el context de l’ensenyament i l’aprenentatge musical. Bàsicament està estructurat en dos grans blocs. D’una banda el marc teòric, el qual proporciona una visió general del funcionament de la memòria a nivell neurològic, psicològic i musical, i dels tipus de memòria existents dels quals ens podem servir per a memoritzar. De l’altra faig una recerca sobre quin paper juga la memòria musical tant en músics formats com en nens que comencen a aprendre música. Els musics formats són representats per una mostra d’alumnes de quart curs i graduats de quatre conservatoris superiors diferents, als que a través d’un qüestionari se’ls demana informació per conèixer de primera mà la seva opinió, vivències i coneixements sobre com utilitzen la memòria. Els nens en formació s’investiguen a través d’un estudi de cas amb la intenció de comprovar què suposa dissenyar activitats d’aprenentatge orientades a facilitar la capacitat de la memòria de les persones que estan començant a aprendre música.

Prostaglandin E2 promotes integrin alpha Vbeta 3-dependent endothelial cell adhesion, rac-activation, and spreading through cAMP/PKA-dependent signaling.

We have recently reported that the inhibition of endothelial cell COX-2 by non-steroidal anti-inflammatory drugs suppresses alpha(V)beta(3)- (but not alpha(5)beta(1)-) dependent Rac activation, endothelial cell spreading, migration, and angiogenesis (Dormond, O., Foletti, A., Paroz, C., and Ruegg, C. (2001) Nat. Med. 7, 1041-1047). Here we investigated the role of the COX-2 metabolites PGE(2) and TXA2 in regulating human umbilical vein endothelial cell (HUVEC) adhesion and spreading. We report that PGE(2) accelerated alpha(V)beta(3)-mediated HUVEC adhesion and promoted Rac activation and cell spreading, whereas the TXA2 agonist retarded adhesion and inhibited spreading. We show that the cAMP level and the cAMP-regulated protein kinase A (PKA) activity are critical mediators of these PGE(2) effects. alpha(V)beta(3)-mediated adhesion induced a transient COX-2-dependent rise in cAMP levels, whereas the cell-permeable cAMP analogue 8-brcAMP accelerated adhesion, promoted Rac activation, and cell spreading in the presence of the COX-2 inhibitor NS-398. Pharmacological inhibition of PKA completely blocked alpha(V)beta(3)-mediated adhesion. A constitutively active Rac mutant (L61Rac) rescued alpha(V)beta(3)-dependent spreading in the presence of NS398 or, but did not accelerate adhesion, whereas a dominant negative Rac mutant (N17Rac) suppressed spreading without affecting adhesion. alpha(5)beta(1)-mediated HUVEC adhesion, Rac activation, and spreading were not affected by PGE(2), 8-brcAMP, or the inhibition of PKA. In conclusion, these results demonstrate that PGE(2) accelerates alpha(V)beta(3)-mediated endothelial cell adhesion through cAMP-dependent PKA activation and induces alpha(V)beta(3)-dependent spreading via cAMP- and PKA-dependent Rac activation and may contribute to the further understanding of the regulation of vascular integrins alpha(V)beta(3) by COX-2/PGE(2) during tumor angiogenesis and inflammation.

Dispersões Aquosas de Poliuretano como Material Base para o Desenvolvimento de Sistemas de Libertação Controlada de Cetoprofeno

O cetoprofeno (ácido 2-(3-benzoilfenil) propiónico) é um anti-inflamatório não esteroidal (AINE) utilizado no tratamento de uma grande variedade de doenças inflamatórias agudas e crónicas incluindo a artrite reumatoide, osteoartrite e espondilite anquilosante. A sua administração oral prolongada está associada a diversas reações gastrointestinais, tais como irritações e ulcerações. Neste contexto, é importante desenvolver sistemas alternati-vos, nomeadamente sistemas de libertação controlada para administração oral, transdér-mica ou intradérmica. Este trabalho tem como objetivo testar a possibilidade de utilização de dispersões aquosas de poliuretano (PUDs) como material de suporte para a produção de sistemas de liberta-ção controlada de cetoprofeno. Numa primeira etapa, foram sintetizadas PUDs de base poliéster (policaprolactona, PCL) e poliéter (polipropileno-glicol, PPG) utilizando o méto-do de pré-polímero modificado. As dispersões obtidas foram caracterizadas em termos de pH, viscosidade, teor de sólidos e tamanho de partícula. Numa segunda etapa, foi testada a incorporação do cetoprofeno nas PDUs produzidas utilizando duas estratégias para incre-mentar a sua solubilidade em água: (i) utilização de um co-solvente (acetona, DMSO e HYD) e (ii) utilização de um surfactante não iónico (Tween 80). A incorporação foi testada para teores de 5% e 10% (razão fármaco/polímero, m/m). Os filmes produzidos pelo méto-do da evaporação do solvente foram avaliados quanto à sua homogeneidade e caracteriza-dos por FTIR e DSC. Numa terceira fase realizaram-se estudos de libertação em tampão de fosfato salino (PBS) de pH 7.5 tendo como objetivo avaliar a viabilidade de desenvolvimen-to de diferentes tipologias de dispositivos dependendo de um compromisso entre as pro-priedades dos filmes e o comportamento de libertação. Os resultados obtidos podem ajudar na seleção do material de base mais adequado para um determinado fim. Adicionalmente, e mais importante, comprovou-se a viabilidade de utilizar PUDs como material base para o desenvolvimento de sistemas de libertação con-trolada, utilizando como exemplo o cetoprofeno. A avaliação da toxicidade e da atividade anti-inflamatória dos filmes produzidos foi considerada estando em curso neste momento no grupo do Professor Armando Cunha Júnior.
