Redes de inovação: mapeamento de inventores de patentes em uma empresa do setor de cosméticos

This article aims to identify patterns in the organization of innovation network by mapping the network inventors of a cosmetics company and identifying ways to promote innovation capacity through interconnectivity. The research was conducted through case study methods, and, for this, inventors mappings were made, based on the records of patents previously surveyed, taking into consideration the linkage (internal or external) of each inventor with the company and also the amount of patent citations. It was identified higher hierarchy in networks with the presence of collaborators externals to the company as well as a possible higher technological content, since the amount of citations was higher compared to other networks. It is verified, finally, that inventors mappings (although a patent is not the only measuring factor of innovation) can identify key features to help a better management of innovation.

Discovery and redescription of type material of Nausithoe simplex (Kirkpatrick, 1890), comb. nov (Cnidaria: Scyphozoa: Coronatae: Nausithoidae) from the North Atlantic

With discovery and examination of type specimens in the Natural History Museum, London, UK, we reassign Stephanoscyphistoma simplex (Kirkpatrick, 1890) to the genus Nausithoe Kolliker, 1853, as Nausithoe simplex, comb. nov., and designate a lectotype for the species. Use of morphometric measurements is considered important in coronate systematics, but key features also include the unique whorl of internal cusps and the shape of these cusps. All previous records of N. simplex must be re-evaluated, taking into consideration the morphology of these internal cusps.

Redescription of the larva of Amblyomma oblongoguttatum Koch, 1844 (Acari: Ixodidae) by light and scanning electron microscopy

The larval stage of Amblyomma oblongoguttatum Koch is redescribed using optical and scanning electron microscopy. Unfed larvae were obtained from a colony of A. oblongoguttatum originated from engorged females collected on domestic pigs from Monte Negro municipally (10 degrees 29'S, 63 degrees 32'W), State of Rondonia, Western Amazon, Brazil. Several characters are presented including the chaetotaxy of the idiosoma, palpi and Haller's organ, as well as morphological features of the idiosoma, gnathosoma and legs. In addition, the porotaxy (topographical and numerical patterns of integumentary structures) were presented by using a new nomenclature recently proposed. The chaetotaxy of the larvae of A. oblongoguttatum, in general, is similar to other Neotropical Amblyomma species. Three types of integumentary structures were observed on the idiosoma: lyrifissures, small glands, and large wax glands. Topographic and numerical patterns of the integumentary structures consisted of 5 pairs of large wax glands (1 dorsal/4 ventral), 24 pairs of lyrifissures (11 dorsal/13 ventral), and 49 pairs of small glands (28 dorsal/21 ventral). These topographic and numerical patterns found for A. oblongoguttatum show only minor differences when compared with patterns of other Amblyomma larvae, however, a few key features can be used for identification of these species.

Representations as tools of appropriation, creating meaning through activities.

Based on some constructs of the Activity Theory (Leontiev, 1978), we point to the need to develop activities that reveal the meaning of representations. We examine use of representations in teaching and propose some suggestions. Shaaron Ainsworth (1999) asserted that, in order to learn from engaging with multiple representations of scientific concepts, students need to be able to (a) understand the codes and signifiers in a representation, (b) understand the links between the representation and the target concept or process, (c) translate key features of the concept across representations and (d) know which features to emphasize in designing their own representations.

Integration of MFA and LCA methodologies: the anthropogenic aluminium cycle in Italy

MFA and LCA methodologies were applied to analyse the anthropogenic aluminium cycle in Italy with focus on historical evolution of stocks and flows of the metal, embodied GHG emissions, and potentials from recycling to provide key features to Italy for prioritizing industrial policy toward low-carbon technologies and materials. Historical trend series were collected from 1947 to 2009 and balanced with data from production, manufacturing and waste management of aluminium-containing products, using a ‘top-down’ approach to quantify the contemporary in-use stock of the metal, and helping to identify ‘applications where aluminium is not yet being recycled to its full potential and to identify present and future recycling flows’. The MFA results were used as a basis for the LCA aimed at evaluating the carbon footprint evolution, from primary and electrical energy, the smelting process and the transportation, embodied in the Italian aluminium. A discussion about how the main factors, according to the Kaya Identity equation, they did influence the Italian GHG emissions pattern over time, and which are the levers to mitigate it, it has been also reported. The contemporary anthropogenic reservoirs of aluminium was estimated at about 320 kg per capita, mainly embedded within the transportation and building and construction sectors. Cumulative in-use stock represents approximately 11 years of supply at current usage rates (about 20 Mt versus 1.7 Mt/year), and it would imply a potential of about 160 Mt of CO2eq emissions savings. A discussion of criticality related to aluminium waste recovery from the transportation and the containers and packaging sectors was also included in the study, providing an example for how MFA and LCA may support decision-making at sectorial or regional level. The research constitutes the first attempt of an integrated approach between MFA and LCA applied to the aluminium cycle in Italy.

"Tra centro e periferia" Istituzioni e processi di industrializzazione nella Sicilia del secondo dopoguerra

In Sicilia lo strumento principale che ha caratterizzato le modalità d’intervento dei poteri pubblici in economia è stato quello della partecipazione diretta o indiretta, quello cioè della Regione che si propone come ente fautore del sostegno allo sviluppo dell’industria e successivamente come soggetto imprenditore. Le formule organizzative attraverso le quali si è concretizzato l’intervento regionale in economia furono la società per azioni a partecipazione regionale, l’azienda autonoma regionale e l’ente pubblico regionale1. La storia dello sviluppo economico siciliano nel secondo dopoguerra conferma come il ricorso allo strumento dell’ente pubblico economico sia stato molto frequente nella realtà locale come, peraltro, anche in altre Regioni d’Italia. Tracce, queste, di una vicenda storica che intuiamo subito avere complesse implicazioni tali da generare la necessità di interrogarsi sul modo nel quale le istituzioni politiche hanno influito sulle dinamiche economiche siciliane nel secondo dopoguerra; per quanto noti e approfonditi siano stati infatti gli elementi caratterizzanti e i percorsi peculiari dello sviluppo economico siciliano, rimangono scarsamente approfonditi il tenore dei rapporti e i nessi politici, istituzionali ed economici tra centro e periferia, in altre parole rimane ancora parzialmente inesplorata quella parte dell’indagine inerente l’evoluzione dei processi di industrializzazione della Sicilia nel secondo dopoguerra attuata parallelamente dalle autorità regionali e dallo Stato attraverso i loro enti e strumenti. È lecito chiedersi quali siano stati i tempi, le modalità, gli ostacoli e gli eventuali risultati delle azioni di pianificazione intraprese dai poteri pubblici centrali e regionali nella prospettiva dello sviluppo economico del territorio; il coordinamento delle azioni di promozione del progresso industriale si presentava in tal senso, sin dall’inizio, come una delle sfide fondamentali per un adeguato e consistente rilancio economico delle aree più arretrate del Mezzogiorno italiano; ecco che lo studio dei provvedimenti legislativi emanati rappresenta un approfondimento indispensabile e obiettivo primario di questo lavoro.

Expression und Funktion der Paraoxonase-2 im Hinblick auf oxidativen Stress im Gefäßsystem

Erhöhte Spiegel von oxidativem Stress bedingen Atherosklerose, eine Krankheit die über 50% aller Todesfälle in der westlichen Welt ausmacht. Es ist entscheidend Mechanismen zur Abwehr dieser Krankheit zu ergründen.rnDa genetische Polymorphismen des körpereigenen Enzyms Paraoxonase 2 (PON2) mit kardiovaskulären Erkrankungen assoziiert sind, wurden ihre Regulation und potentiell antioxidativen Funktionen in vaskulären Zellen analysiert. Mittels verschiedener molekularbiologischer Methoden konnte ich erstmals zeigen, dass PON2 in vaskulären Zellen vornehmlich subzellulär im ER lokalisiert ist. Anhand verschiedener Experimente wurde PON2 als potenter Faktor zur Reduktion von ROS identifiziert. Erhöhte ROS-Spiegel führen zur Aktivierung eines als unfolded protein response (UPR) bekannten ER-Stress-Signalwegs. Dieser ist neben Atherosklerose in eine Vielzahl von Erkrankungen involviert und hat kritischen Einfluss auf das Überleben oder Absterben von Zellen. Durchgeführte Promoter-Reporter Studien bewiesen die Induktion der Protein-Expression von PON2 nach Aktivierung des UPR-Signalwegs, was als kompensatorischer Mechanismus der Zelle zur Vermeidung UPR-induzierter Apoptose verstanden werden könnte. PON2 wehrt oxidativen Stress und die UPR-induzierte Apoptose ab und ist ein protektiver Faktor vor Atherosklerose.rnIn einem Krebsmodell könnte PON2 aber als antiapoptotischer Faktor entscheidend am Überleben von Tumorzellen beteiligt sein. Gerade diese beiden gegensätzlichen Aspekte der antiapoptotischen Funktion des Proteins zeigen die Notwendigkeit für weitere Untersuchungen zu PON2 auf.rn

Activation of the unfolded protein response in human acute myeloid leukemia

There is accumulating evidence for the involvement of the unfolded protein response (UPR) in the pathogenesis of many tumor types in humans. This is particularly the case in rapidly growing solid tumors in which the demand for oxygen and nutrients can exceed the supply until new tumor-initiated blood vessels are formed. In contrast, the role of the UPR during leukemogenesis remains largely unknown. Acute myeloid leukemia (AML) is a genetically heterogeneous clonal disorder characterized by the accumulation of somatic mutations in hematopoietic progenitor cells that alter the physiological regulation of self-renewal, survival, proliferation, or differentiation. The CCAAT/enhancer-binding protein alpha (CEBPA) gene is a key myeloid transcription factor and a frequent target for disruption in AML. In particular, translation of CEBPA mRNA can be specifically blocked by binding of the chaperone calreticulin (CALR), a well-established effector of the UPR, to a stem loop structure within the 5' region of the CEBPA mRNA. The relevance of this mechanism was first elucidated in certain AML subtypes carrying the gene rearrangements t(3;21) or inv(16). In our recent work, we could demonstrate the induction of key effectors of the UPR in leukemic cells of AML patients comprising all subtypes (according to the French-American-British (FAB) classification for human AML). The formation of the spliced variant of the X-box binding protein (XBP1s) was detectable in 17.4% (17 of 105) of AML patients. Consistent with an activated UPR, this group had significantly increased expression of the UPR target genes CALR, the 78 kDa glucose-regulated protein (GRP78), and the CCAAT/enhancer-binding protein homologous protein (CHOP). Consistently, in vitro studies confirmed that calreticulin expression was upregulated via activation of the ATF6 pathway in myeloid leukemic cells. As a consequence, CEBPA protein expression was inhibited in vitro as well as in leukemic cells from patients with activated UPR. We therefore propose a model of the UPR being involved in leukemogenesis through induction of calreticulin along the ATF6 pathway, thereby ultimately suppressing CEBPA translation and contributing to the block in myeloid differentiation and cell-cycle deregulation which represent key features of the leukemic phenotype. From a more clinical point of view, the presence of activated UPR in AML patient samples was found to be associated with a favorable disease course.

Cellular and immunological basis of the host-parasite relationship during infection with Neospora caninum

Neospora caninum is an apicomplexan parasite that is closely related to Toxoplasma gondii, the causative agent of toxoplasmosis in humans and domestic animals. However, in contrast to T. gondii, N. caninum represents a major cause of abortion in cattle, pointing towards distinct differences in the biology of these two species. There are 3 distinct key features that represent potential targets for prevention of infection or intervention against disease caused by N. caninum. Firstly, tachyzoites are capable of infecting a large variety of host cells in vitro and in vivo. Secondly, the parasite exploits its ability to respond to alterations in living conditions by converting into another stage (tachyzoite-to-bradyzoite or vice versa). Thirdly, by analogy with T. gondii, this parasite has evolved mechanisms that modulate its host cells according to its own requirements, and these must, especially in the case of the bradyzoite stage, involve mechanisms that ensure long-term survival of not only the parasite but also of the host cell. In order to elucidate the molecular and cellular bases of these important features of N. caninum, cell culture-based approaches and laboratory animal models are being exploited. In this review, we will summarize the current achievements related to host cell and parasite cell biology, and will discuss potential applications for prevention of infection and/or disease by reviewing corresponding work performed in murine laboratory infection models and in cattle.

A MULTILEVEL MODEL TO ADDRESS BATCH EFFECTS IN COPY NUMBER ESTIMATION USING SNP ARRAYS

Submicroscopic changes in chromosomal DNA copy number dosage are common and have been implicated in many heritable diseases and cancers. Recent high-throughput technologies have a resolution that permits the detection of segmental changes in DNA copy number that span thousands of basepairs across the genome. Genome-wide association studies (GWAS) may simultaneously screen for copy number-phenotype and SNP-phenotype associations as part of the analytic strategy. However, genome-wide array analyses are particularly susceptible to batch effects as the logistics of preparing DNA and processing thousands of arrays often involves multiple laboratories and technicians, or changes over calendar time to the reagents and laboratory equipment. Failure to adjust for batch effects can lead to incorrect inference and requires inefficient post-hoc quality control procedures that exclude regions that are associated with batch. Our work extends previous model-based approaches for copy number estimation by explicitly modeling batch effects and using shrinkage to improve locus-specific estimates of copy number uncertainty. Key features of this approach include the use of diallelic genotype calls from experimental data to estimate batch- and locus-specific parameters of background and signal without the requirement of training data. We illustrate these ideas using a study of bipolar disease and a study of chromosome 21 trisomy. The former has batch effects that dominate much of the observed variation in quantile-normalized intensities, while the latter illustrates the robustness of our approach to datasets where as many as 25% of the samples have altered copy number. Locus-specific estimates of copy number can be plotted on the copy-number scale to investigate mosaicism and guide the choice of appropriate downstream approaches for smoothing the copy number as a function of physical position. The software is open source and implemented in the R package CRLMM available at Bioconductor (http:www.bioconductor.org).

Supersymmetric Mode Converters

Originally developed in the context of quantum field theory, the concept of supersymmetry can be used to systematically design a new class of optical structures. In this work, we demonstrate how key features arising from optical supersymmetry can be exploited to control the flow of light for mode division multiplexing applications. Superpartner configurations are experimentally realized in coupled optical networks, and the corresponding light dynamics in such systems are directly observed. We show that supersymmetry can be judiciously utilized to remove the fundamental mode of a multimode optical structure, while establishing global phase matching conditions for the remaining set of modes. Along these lines, supersymmetry may serve as a promising platform for versatile optical components with desirable properties and functionalities.

A novel comparative research platform designed to determine the functional significance of tree species diversity in European forests

One of the current advances in functional biodiversity research is the move away from short-lived test systems towards the exploration of diversity-ecosystem functioning relationships in structurally more complex ecosystems. In forests, assumptions about the functional significance of tree species diversity have only recently produced a new generation of research on ecosystem processes and services. Novel experimental designs have now replaced traditional forestry trials, but these comparatively young experimental plots suffer from specific difficulties that are mainly related to the tree size and longevity. Tree species diversity experiments therefore need to be complemented with comparative observational studies in existing forests. Here we present the design and implementation of a new network of forest plots along tree species diversity gradients in six major European forest types: the FunDivEUROPE Exploratory Platform. Based on a review of the deficiencies of existing observational approaches and of unresolved research questions and hypotheses, we discuss the fundamental criteria that shaped the design of our platform. Key features include the extent of the species diversity gradient with mixtures up to five species, strict avoidance of a dilution gradient, special attention to community evenness and minimal covariation with other environmental factors. The new European research platform permits the most comprehensive assessment of tree species diversity effects on forest ecosystem functioning to date since it offers a common set of research plots to groups of researchers from very different disciplines and uses the same methodological approach in contrasting forest types along an extensive environmental gradient.
