Lipid overload in obesity and type 2 diabetes is associated with adipocyte dysfunction, inflammation, macrophage infiltration, and decreased fatty acid oxidation (FAO). Here, we report that the expression of carnitine palmitoyltransferase 1A (CPT1A), the rate-limiting enzyme in mitochondrial FAO, is higher in human adipose tissue macrophages than in adipocytes and that it is differentially expressed in visceral vs. subcutaneous adipose tissue in both an obese and a type 2 diabetes cohort. These observations led us to further investigate the potential role of CPT1A in adipocytes and macrophages. We expressed CPT1AM, a permanently active mutant form of CPT1A, in 3T3-L1 CARΔ1 adipocytes and RAW 264.7 macrophages through adenoviral infection. Enhanced FAO in palmitate-incubated adipocytes and macrophages reduced triglyceride content and inflammation, improved insulin sensitivity in adipocytes, and reduced endoplasmic reticulum stress and ROS damage in macrophages. We conclude that increasing FAO in adipocytes and macrophages improves palmitate-induced derangements. This indicates that enhancing FAO in metabolically relevant cells such as adipocytes and macrophages may be a promising strategy for the treatment of chronic inflammatory pathologies such as obesity and type 2 diabetes.

In 2009 the University of Girona (Spain) created four interest groups on teaching innovation. The objective of the project is that lecturers with an interest in teaching innovation can exchange their points of view and learn from one another, so University teaching is improved as a result. There are four such groups: “Problem based learning (ABP)”, “Cooperative learning”, “Evaluation”, and “Information and Communication Technologies (ICTs) and Teaching”. The coordinators of the groups or networks, as they are also called, are chosen on a free basis by its members. This paper presents their point of view as regards the current activity of encouragement of interest in higher education and they elaborate on the main difficulties involved. The implications of the interdisciplinary work are explored, as well as the challenges of an initiative of this kind. The evolution of the ongoing work is reviewed, taking into account the context of a changing University, the lack of previous experience regarding projects of this kind, the asynchronous communication among the participants, and the necessity of a flexible approach in organizational matters

relationship between productivity and international position of Spanish chemical firms in the period 2005-2011. The goal is to determine whether companies that follow and international strategy, either with exports or by investment in foreign countries obtain greater productivity growth than these that do not operate in global market. For this purpose a panel data set with microdata has been created. A preliminary analysis of the evolution of productivity growth in the sector is carried out. The measurement of Total Factor Productivity is performed. With the estimated TFP we analyze the differentials in productivity growth, comparing the effects of export and investment behavior with non-international firms.

Oídio (Oidiopsis taurica) é uma importante doença do pimentão (Capsicum annuum) e outras espécies de Capsicum. O objetivo deste trabalho foi identificar fontes de resistência no germoplasma de Capsicum spp. e relatar suas reações ao oídio em ambientes de telado e de casa de vegetação. Em telado, com inoculação artificial, testaram-se 104 genótipos de C. annuum, C. chinense, C. baccatum e C. frutescens. A avaliação foi repetida em canteiros de casa de vegetação com inoculação natural. Em telado, inoculou-se via atomização de 10(4) conídios/ml e em casa de vegetação manteve-se como fonte de inóculo plantas de pimentão previamente infetadas. Os genótipos foram agrupados em cinco níveis de resistência, a partir de leituras periódicas de incidência, esporulação, severidade e intensidade total da doença, e da determinação das respectivas áreas abaixo das curvas de progresso da doença. Cerca de 77% dos genótipos avaliados em telado foram altamente (AS) ou moderadamente suscetíveis (MS); 8% moderadamente resistentes (MR); 11% resistentes (R); e 4% foram altamente resistentes (AR). Cerca de 72% dos genótipos avaliados em casa de vegetação foram AS ou MS; 11% MR; 9% R; e 8% foram AR. Todos os genótipos classificados como AS tanto em telado quanto em casa de vegetação pertencem à espécie C. annuum. De modo geral, o ranking de resistência ao oídio permaneceu constante nos dois ambientes. Capsicum baccatum, C. frutescens e C. chinense apresentaram maior número de genótipos resistentes. Os principais genótipos AR foram CNPH 39, 161, 363 e 601 (C. baccatum); CNPH 579, 596 e 597 (C. frutescens); CNPH 55 (C. chinense); CNPH 280, 289, 434, 570 e 600 (C. chinense) e CNPH 1424 (C. annuum).

This study presents an automatic, computer-aided analytical method called Comparison Structure Analysis (CSA), which can be applied to different dimensions of music. The aim of CSA is first and foremost practical: to produce dynamic and understandable representations of musical properties by evaluating the prevalence of a chosen musical data structure through a musical piece. Such a comparison structure may refer to a mathematical vector, a set, a matrix or another type of data structure and even a combination of data structures. CSA depends on an abstract systematic segmentation that allows for a statistical or mathematical survey of the data. To choose a comparison structure is to tune the apparatus to be sensitive to an exclusive set of musical properties. CSA settles somewhere between traditional music analysis and computer aided music information retrieval (MIR). Theoretically defined musical entities, such as pitch-class sets, set-classes and particular rhythm patterns are detected in compositions using pattern extraction and pattern comparison algorithms that are typical within the field of MIR. In principle, the idea of comparison structure analysis can be applied to any time-series type data and, in the music analytical context, to polyphonic as well as homophonic music. Tonal trends, set-class similarities, invertible counterpoints, voice-leading similarities, short-term modulations, rhythmic similarities and multiparametric changes in musical texture were studied. Since CSA allows for a highly accurate classification of compositions, its methods may be applicable to symbolic music information retrieval as well. The strength of CSA relies especially on the possibility to make comparisons between the observations concerning different musical parameters and to combine it with statistical and perhaps other music analytical methods. The results of CSA are dependent on the competence of the similarity measure. New similarity measures for tonal stability, rhythmic and set-class similarity measurements were proposed. The most advanced results were attained by employing the automated function generation – comparable with the so-called genetic programming – to search for an optimal model for set-class similarity measurements. However, the results of CSA seem to agree strongly, independent of the type of similarity function employed in the analysis.

The condition of Baltic Sea has weakened considerably because of eutrophication which has caused massive increase of devalued fish. The condition of Baltic Sea can be helped by fishing these fish. This study handles three different ways to approach those fish utilizations and counts carbon footprint for those three chains. Environmental point of views are also examined. There are three different fish processing chains. Every processing chain begins with fishing the fish in Baltic Sea. After that the fishes are prepared by crushing and some formic acid is added to ensure preservation. In the first processing chain the fishes are processed as biodiesel. The waste from the biodiesel process is taken to the anaerobic digestion and the forming methane is used as energy. In the second chain the fishes are taken straight to the anaerobic digestion after preparing. In the third chain, the fish will be first prepared and then taken to fur farms as forage. The carbon footprint has been calculated for 1000 kg fish. The carbon footprint in the first chain is 164-178 kg CO2e, in the second chain 313 – 333 kg CO2e and in the third chain 363 kg CO2e. In the processing chains the bioenergy is produced from the biodiesel, anaerobic digestion and from the glycerol, which is by-product of the biodiesel. The energy produced from the biodiesel is so-called emission neutral, which is not taken into account when calculating emissions. The energy is used to compensate the emissions caused by fossil fuels. The PAS 2050 was used to calculate the carbon footprint. Only carbon dioxide and methane were used when calculating the carbon footprint.

O artigo reconstrói alguns momentos salientes do desenvolvimento das doutrinas do 'não-si' e das 'duas verdades' na história da filosofia buddhista, desde as formulações originárias do buddhismo de base, às conclusões alcançadas por Nāgārjuna, o fundador da escola mahāyāna do Madhyamaka. Ao longo dessa sintética reconstrução, algumas passagens das Mūlamadhyamikakārikās de Nāgārjuna, cruciais para entender a sua (controversa) concepção epistemológica, mostrar-se-ão semelhantes, no tocante à estruturação e ao desenvolvimento do discurso, à primeira parte das Milinda Pañha, um diálogo para-canônico que escolhe uma abordagem apofática para tratar o tema da 'verdade última'. Tal paralelismo formal entre as passagens dos dois textos sugere a possibilidade de uma correspondência 'substancial' entre a concepção nagarjuniana e aquela das Milinda Pañha no que se refere ao 'ultimamente verdadeiro'.
