Authors: Stark Fabian , Rosenberger Maik , Dittrich Paul-Gerald , Celestre Rafael , Hänsel Michael , Notni Gunther
Published: June 2017

One way to increase the amount of information acquired via hyperspectral imaging and therefore to increase the possibility
of data analysis is combining the spatial and spectral information of hyperspectral data sets. The aforementioned data
sets are obtained by cameras covering different spectral ranges. The purpose of this article is to develop an algorithm
which is able to combine two data sets acquired by two hyperspectral pushbroom imagers, covering the visible (VIS) and the
near infrared (NIR) wavelength range. Initially, the effect of optical aberrations, as well as errors via the image
registration were examined. Subsequently a correction algorithm for both the optical aberration and the image registration
is elaborated.

Gesamthochschulbibliotheken und Klassifikationsentwicklung im Spannungsfeld zwischen Kooperation und lokalen Bedürfnissen
Authors: Lowisch Maximilian
Published: June 2017

Dieser Beitrag beschreibt die Entwicklung der Gesamthochschulbibliothekssystematik (GHBS) als Aufstellungssystematik der Gesamthochschulbibliotheken (GHBs) in Nordrhein-Westfalen (NRW) seit den 1970er Jahren bis heute. Dabei werden zunächst mittels Literaturauswertung und Archivmaterial entscheidende Entwicklungspunkte kursorisch bis zum Ende der gemeinsamen Pflege der Systematik im Jahre 2004 dargestellt. Die Einflüsse lokaler Interessengruppen sowie technischer Veränderungen auf die kooperative Klassifikationsentwicklung werden betrachtet. Die Untersuchung wird durch Experteninterviews erweitert. Konzeption und Auswertung der Interviews bedienen sich der qualitativen Inhaltsanalyse nach Gläser und Laudel und des Ressourcenabhängigkeitsansatzes (RDT). Aus Experteninterviews und Literaturauswertung wird sich eine heute nur noch nachrangige Bedeutung der Klassifikationsentwicklung sowie ein Mangel an Aufsichts- und Sanktionierungsmaßnahmen gegenüber den GHBs ergeben.
Computational Study on Non-linear Optical and Absorption Properties of Benzothiazole based Dyes: Tunable Electron-Withdrawing Strength and Reverse Polarity
Authors: Janjua Muhammad Ramzan Saeed Ashraf
Published: June 2017

Various organic dyes possessing characteristic D-π-A-A configuration have been designed in this article. The analysis of the relation between polarity of charge transfer and the unsymmetrical nature of the benzothiazole group has been studied. The absorption spectra, electronic characteristic properties and non-linear optical responses were simulated using a quantum chemical approach. The results have indicated that the systems show higher polarizability (α) and hyperpolarizability (β) with commonly used polarity in comparison to the reverse polarity. A red-shifted absorption spectra were observed with systems having common polarities. This study illustrates the rule to design non-linear optical material with low energy charge transfer excited states and high value of oscillation.

The IUPAC centenary in 2019 is fast approaching, and this will naturally lead people to look back at the significant achievements of the organisation and its dedicated volunteers over the past one hundred years. Equally important, however, will be the need to look forward to the roles for IUPAC in its second century. This special issue of Chemistry International (CI) could well feature in that assessment, as technology in the digital age, and particularly the data that technology produces, will clearly be an essential tool for the future of chemistry as a discipline.

Published: June 2017

Objective:

To determine the prevalence, secular trends and associations of heart disease in a large unscreened, otherwise basically healthy, adolescent population.

Subjects and methods:

Cross-sectional study of the cardiac status of 113,694 adolescents from the northern district of Israel, who completed the profiling process between the ages of 16 and 19, including all essential measures over a 22-year period.

Results of imaging were categorized as either isolated valvar or structural abnormalities, and their clinically significant subgroups defined prospectively. The findings were correlated with the socio-demographic and anthropometric data and non-cardiac health conditions.

Results:

Of those sent for echocardiography, 1257 (0.93% of the total population) had isolated valvar disease and 216 (0.19%) had structural abnormalities, with 20% of both groups considered significant. Females had lower prevalence of heart disease. There was peak prevalence in the second 5-year period. Tall subjects or a past history of rheumatic fever had more valvar abnormalities. Thin subjects or those with skeletal anomalies had more structural abnormalities. Significant valvar and structural anomalies were more common in subjects with learning disorders, endocrine disorders and diabetes mellitus. Fewer valvar abnormalities were diagnosed in obese subjects. Heart disease was more common in those with non-solid tumors.

Conclusion:

Appreciable numbers of potentially healthy adolescents were found to have heart disease. There appeared to be an association with body size, skeletal abnormalities and relatively common medical disorders, the cause of which remains to be determined in prospective studies that could change the way common adolescent disease should be followed.
Das kantische Raummodell in der Neurobiologie
Authors: Schwarzkopf Grit , Monyer Hannah
Published: June 2017

The neurobiological findings of the Nobel laureates John O’Keefe, May-Britt Moser and Edvard Moser have been widely discussed in the context of a “Kantian View of Space”. Thus, spatially tuned cells have been considered the physiological substrate of Kant’s a priori representation of space. Based on neuroscientific and philosophical considerations, the authors maintain that such an interpretation is misleading. Referring to Kant’s own arguments in dealing with Soemmerring’s assertion according to which the cerebral fluid of the ventricles constitutes the physiological substrate of the soul, the authors argue that attributing epistemic functions to a physiological substrate constitutes a vitium subreptionis. However, when used as an analogy, the transfer of concepts from one discipline to another can promote the interdisciplinary dialogue, as shown here on the example of the a priori representation of space.
Study on maintaining formations during satellite formation flying based on SDRE and LQR
Authors: Ke Zhang , Zhenqi He , Meibo Lv
Published: June 2017

Due to the influence of various perturbations of space, satellites flying in formation cannot maintain specific configurations for long durations [1, 2]. In order to ensure that formation configurations are able to meet the requirements of space missions, it is important to maintain control of formation configurations. This is an urgent problem to be solved. The traditional control method for controlling formations is based on the average orbit element, and uses the assumption that the average orbit element deviation and the instantaneous orbit element deviation are approximately equal. However, the continuous control system is more difficult to achieve in engineering practice. Using a LQR (linear quadratic regulator) optimal control algorithm and SDRE (state-dependent Riccati equation) optimal control algorithm to maintain the formation flying [3, 4]. Through simulation, it was found that when using the SDRE controller in the system transition process time is shorter than when the LQR controller is used, and fuel consumption is less for the SDRE controller than for the LQR controller.

Background

To analyze protective/regenerative effects of adipose tissue-derived mesenchymal stem cells (ADMSC) on 131I-Radioiodine (RAI)-induced salivary gland damage in rats.

Materials and Methods

Study population consisted of controls (n:6) and study groups (n:54): RAI (Group 1), ADMSC (Group 2), amifostine (Group 3), RAI+amifostine (Group 4), concomitant RAI+ADMSC (Group 5) and RAI+ADMSC after 48 h (Group 6). We used light microscopy (LM), transmission electron microscopy (TEM), and salivary gland scintigraphy (SGS), and analyzed data statistically.

Results

We observed the homing of ADMSC in salivary glands at 1st month on LM. RAI exposure affected necrosis, periductal fibrosis, periductal sclerosis, vascular sclerosis and the total sum score were in a statistically significant manner (P < 0.05). Intragroup comparisons with LM at 1st and 6th months revealed statistically significant improvements in Group 6 (P < 0.05) but not in Groups 4 and 5. Intergroup comparisons of the total score showed that Groups 4 and 5 in 1st month and Group 6 in 6th month had the lowest values. TEM showed vacuolization, edema, and fibrosis at 1st month, and an improvement in damage in 6th month in Groups 5 and 6. SGSs revealed significant differences for the maximum secretion ratio (Smax) (P = 0.01) and the gland-to-background ratio at a maximum count (G/BGmax) (P = 0. 01) at 1st month, for G/BGmax (P = 0.01), Smax (P = 0.01) and the time to reach the maximum count ratio over the time to reach the minimum count (Tmax/Tmin) (P = 0.03) at 6th month. 1st and 6th month scans showed differences for Smax and G/BGmax (P = 0.04), but not for Tmax/Tmin (p > 0.05). We observed a significant deterioration in gland function in group 1, whereas, mild to moderate deteriorations were seen in protective treatment groups.

Conclusions

Our results indicated that ADMSC might play a promising role as a protective/regenerative agent against RAI-induced salivary gland dysfunction.
La sémiotique de Greimas: Une épistémologie (discursive) immanente
Authors: Beividas Waldir
Published: June 2017

The concept of immanence occupies today a central and, at the same time, uncomfortable place among semioticians. Some criticize it overtly, others feel the concept has fulfilled its role as a methodological regulator of descriptions and its scope that should be enlarged so as to integrate context, practices, interactions, in short, the human experience. This paper presents immanence through another light. According to Hjelmslev’s Prolegomena, after having suspended transcendent data in the name of methodological immanence – as “the price that had to be paid to elicit from language itself its secret” – “immanence and transcendence are joined in a higher unity on the basis of immanence.” From the methodological level, we move up to the epistemological level of knowledge, whose main thesis condenses its reach: language is the form by which we conceive the world. Greimas also has piercing formulations in this sense. He embraces the immanent methodology and presents his semiotics as an immanent epistemology of knowledge. In this sense, he proposes that science in its entirety is one single language, where the natural sciences operate on the expression plane and the humanities operate on the content plane of this macro-language.

Totgesagte leben länger: Stabilität und Kontinuität der Sozialpartnerschaft in Österreich.
Authors: Hinterseer Tobias
Published: June 2017

Nach einer Reihe von Zäsuren des politischen Systems im Allgemeinen und der Sozialpartnerschaft im Besonderen, vor allem aber nach der Bildung einer Mitte-rechts-Regierung durch die Österreichische Volkspartei (ÖVP) und die Freiheitliche Partei Österreichs (FPÖ) im Jahr 2000, konstatierte die österreichische Politikwissenschaft einen Verlust von politischer Einflussnahme beziehungsweise einen Rückgang der Gestaltungspotenziale der Sozialpartnerschaft und des Austrokorporatismus. Doch bereits während dieser „Zäsurzeit“ und in weiterer Folge mit der Neuauflage der Großen Koalition kam es zu einem Wiederaufschwung der Sozialpartnerschaft, in der diese ihren Einfluss und ihre Machtposition wieder stärken und festigen konnte. Dieses Papier möchte die folgende Fragestellung beantworten: Was sind die Erklärungen für die Stabilität und Kontinuität der Sozialpartnerschaft in der Phase der Zurückdrängung zwischen den Jahren 2000 und 2006? Anhand der Analyse von zwei Gesetzgebungsprozessen wird gezeigt, dass institutionelle und akteursbezogene Faktoren und vor allem durch tradierte sozialpartnerschaftliche Identitäten geprägte Erwartungssicherheiten auch in Zeiten der politischen Zäsur und potenzieller politischer Entmachtung ein starker Garant für den Weiterbestand dieses Systems und die Kontinuität und Stabilität des Austrokorporatismus sind.

Of Digital Selves and Digital Sovereignty: Of the North
Authors: Stewart Michelle
Published: June 2017

At its Canadian premier, Dominic Gagnon's Of the North (2015) launched a passionate debate regarding the ethics of image appropriation and digital filmmaking about Indigenous communities. Of the North follows Gagnon's “natively” digital method, which involves the sampling and montage of public domain images and sounds posted by internauts with the stated intent of documenting how people represent themselves online. In a controversy that crystallized around questions of “digital sovereignty,” Inuit critics decried the recontextualization of personal video posts by a film, they argued, that did not promote an Inuit view of Inuit experience. This article addresses the ways in which Gagnon's digital method collapsed cultural contexts, bringing to light divergent cultural and generational expectations regarding digital presence and sovereignty. An analysis of the film's heated reception and new digital works by young Indigenous filmmakers suggests an intercultural ethics for visual ethnographies.

FQ Columnist Bilal Qureshi reflects on Deepa Mehta's film Earth at an important moment in Indian and global history. Writing from New Delhi, he had the opportunity to speak to Mehta in person about her life and work, and that discussion is woven into this column. Since making Earth almost twenty years ago, Deepa Mehta has seen her stature grow to include film festival premieres, an Oscar nomination, and a platform as one of the rare women auteurs on the international stage. She has lived in Canada since the 1970s, but her most celebrated films are not about immigrant displacement or hyphenated identity. Rather, she has always told Indian stories. From the groundbreaking story of a lesbian relationship between two housewives in suffocating arranged marriages (Fire, 1996) to the forced exile of widows in orthodox Hindu scripture (Water, 2005), she has confronted uncomfortable social realities in Indian society. Although she has been labeled an anti-national and had sets burned and cinemas attacked by the religious right for insulting traditional values, she has taken the challenges in stride and continued making films.

Columnist Paul Julian Smith puts a Mexican TV hit that has gone global into perspective for FQ's readers. Sor Juana Inés de la Cruz, the seventeenth-century poet and nun, has a good claim to be the best-known woman in the history of Mexico. Looking scholarly on the two-hundred-peso banknote, where she is depicted with an ink quill and a volume of her collected works, she has long been an incongruous presence among the virile Aztecs, revolutionaries, and presidents that grace the rest of Mexican currency. But only now has she been awarded that special honor: a biographical television series on her richly resonant and mysterious life. Patricia Arriaga Jordán, perhaps the most distinguished television producer in the country, created Juana Inés for Canal 11, the free public broadcast channel owned by the Instituto Politécnico Nacional university with which she has long collaborated. The seven-hour-long episodes were broadcast nationally twice a week in prime time beginning on March 26, 2016, and subsequently sold for international distribution to Netflix where, at the time of writing, they are available in the United States.

Read in the context of the recent U.S. presidential election, Jackie (Pablo Larraín, 2016) and Christine (Antonio Campos, 2016) inspire important questions about how women are remembered and valued in political and media culture. Jackie explores Jacqueline Kennedy's orchestration of President Kennedy's funeral and legacy, and in so doing provides an inauspicious reminder of how long and how easily Americans have conflated celebrity and politics, how willingly that national audience has embraced national images over national substance. Christine, also organized around one woman's mediation of a violent death (in this case her own), recreates Christine Chubbuck's world in the weeks leading up to her on-air suicide not to explain her actions but to frame the questions that suicide leaves behind. Both films revisit and revise the biopic genre and its inherent limits while also illustrating its political potential. While Jacqueline Kennedy was already part of the U.S. cultural pantheon and Christine Chubbuck was not, both of their biopics use violence, death, and the questions they leave to help viewers think about the ways that women are and are not remembered, let alone mythologized, in an enduring patriarchy.

Spongy degeneration with cerebellar ataxia (SDCA) is a genetically heterogeneous neurodegenerative disorder with autosomal recessive inheritance in Malinois dogs, one of the four varieties of the Belgian Shepherd breed. Using a combined linkage and homozygosity mapping approach we identified an ∼10.6 Mb critical interval on chromosome 5 in a Malinois family with four puppies affected by cerebellar dysfunction. Visual inspection of the 10.6 Mb interval in whole-genome sequencing data from one affected puppy revealed a 227 bp SINE insertion into the ATP1B2 gene encoding the β2 subunit of the Na+/K+-ATPase holoenzyme (ATP1B2:c.130_131insLT796559.1:g.50_276). The SINE insertion caused aberrant RNA splicing. Immunohistochemistry suggested a reduction of ATP1B2 protein expression in the central nervous system of affected puppies. Atp1b2 knockout mice had previously been reported to show clinical and neurohistopathological findings similar to the affected Malinois puppies. Therefore, we consider ATP1B2:c.130_131ins227 the most likely candidate causative variant for a second subtype of SDCA in Malinois dogs, which we propose to term spongy degeneration with cerebellar ataxia subtype 2 (SDCA2). Our study further elucidates the genetic and phenotypic complexity underlying cerebellar dysfunction in Malinois dogs and provides the basis for a genetic test to eradicate one specific neurodegenerative disease from the breeding population in Malinois and the other varieties of the Belgian Shepherd breed. ATP1B2 thus represents another candidate gene for human inherited cerebellar ataxias, and SDCA2-affected Malinois puppies may serve as a naturally occurring animal model for this disorder.
ISOLATION OF LIPOLYTIC BACTERIA FROM COLOMBIAN ANDEAN SOILS: A TARGET FOR BIOPROSPECTING
Authors: Andrea Palacios Jaramillo Paola , Borda-Molina Daniel , Salvador Montaña JosÃ© , Baena Sandra
Published: June 2017

Microbial enrichments with a substrate of interest could enhance the possibility of finding certain desired metabolic activities. As lipases are one of the most important enzymes in industrial applications, the Colombian Andean soils were explored as a source of lipolytic microorganisms. Two Andean soils under low temperatures were sampled: paramo and glacier soils from “Los Nevados” National Natural Park. Both soils were enriched through a fed-batch fermentation using olive oil as the inductor substrate. Forty-three lipolytic isolates were obtained and their taxonomic assignments were performed on the basis of 16S rDNA gene sequencing. In both cases, the phylum Proteobacteria represented the majority of the isolates. Qualitative assays to measure the lipolytic activity were performed by using tributyrin, triolein or olive oil (1%). Two isolates identified as Pseudomonas psychrophila and Stenotrophomonas rhizophila produced the largest hydrolysis halos, with an optimal activity at pH 8 and 50°C. Only the S. rhizophila extracellular fraction hydrolyzed short and long chain pNP-esters, including pNP-palmitate. The broader substrate specificity of this isolate is probably due to the simultaneous presence of lipase and esterase activity in the crude extract. This is the first report of lipolytic activity in S. rhizophila, and the first preliminary characterization of the novel lipolytic activity in S. rhizophila and P. psychrophila. Further work is needed to purify and completely characterize the esterases and lipases produced by both species.

Published: June 2017

The present investigation aimed to study antimicrobial activities in marine microalgae, screened from Moroccan coastlines. Ethanolic extracts were prepared from the microalgae and evaluated each against the bacteria: Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus, the yeast Candida albicans and the fungus Aspergillus niger. The highest antibacterial activity was found in the extract of Tetraselmis sp. which exhibited an inhibitory effect against the three bacteria with a MIC of 2.6 to 3.0 mg extract per mL culture. Extracts from the other microalgae: Dunaliella Salina, Nannochloropsis gaditana, Dunaliella sp., Phaeodactylum tricornutum and Isochrisis sp. each showed inhibitory activity against E. coli or P. aeruginosa with a MIC of 2.6 to 4.3 mg extract per mL. The extract of N. gaditana also inhibited S. aureus growth. However, the extracts from the microalgae, Chaetoceros sp. and Chlorella sp. showed no effect under the applied experimental conditions. All the tested extracts inhibited the growth of C. albicans; the highest activity was obtained from N. gaditana with a MIC of 4.0 mg extract per mL culture. Aspergillus niger appeared to be resistant to the effect of the extracts. The observed antimicrobial activities were linked to the contents of the extracts in fatty acids, carotenoids and phenolic compounds. In conclusion, the studied microalgae could be considered as a potential natural source of bioactive compounds with antimicrobial activities.

The results demonstrated that the pH stability of the immobilized enzyme significantly increased in comparison with free enzyme. The immobilized enzyme was usable and recoverable for seven cycles. The results depicted that 80% of enzyme activity was retained after fifth cycle. FTIR test showed the covalent binding of enzyme to magnetic nanoparticles’ surface and the modified enzyme magnetic nanoparticles property was superparamagnetic by vibrating sample magnetometer test.
Effect of Eucalyptus globullus biochar addition on the availability of phosphorus in acidic soil
Authors: Martínez C. María José , España A. Julio César , Diaz V. José De Jesus
Published: June 2017

Phosphorus (P) is one of the primary nutrients limiting crop production. The application of phosphate fertilizers in acidic soils leads to the formation of secondary insoluble compounds that reduces the effectiveness of the fertilizer. The addition of biochar may represent a solution to the problem of nutrients bioavailability, especially P. In this study, tests were performed to determine the effects of amending soil with five different percentages of biochar (0, 5, 10, 20, and 35% w/w) on the phenomena of P sorption and desorption. The effect of soil/ biochar contact treatments on P availability was also examined. Phosphorus sorption was lower in the soils containing biochar compared to normal soil. The accumulated desorption quantity after eight consecutive extractions was 85% higher when 35% biochar was added to the soil than soil alone. Moreover, the application of 35% biochar increased the concentration of soluble P up to 38% after 30 days of incubation. Based on these results, we deduced that biochar induces changes in P retention soil properties that may be beneficial for agricultural soils.

'Arrayana' tangerine (Citrus reticulta Blanco) is the most cultivated variety in Meta piedmont; it is mainly grafted onto the 'Cleopatra' tangerine rootstock (Citrus reshni hort. ex Tanaka). Plants grafted onto this rootstock have a late production entrance, produce big plants and their yield is affected by the rainfall patterns that occur during the dry season. Five rootstocks were evaluated to identify the one with the best productive performance for 'Arrayana' tangerine. The experiment was established in 1997. The report of the first five harvest was published in 2006. This report shows the results of six additional pickings. The rootstocks with the highest yields were citrumelo 'Swingle' (CPB 4475) and Sunki x English (SxE), without statistical differences, followed by Sunki x Jacobson (SxJ) (no statistical differences with SxE), 'Cleopatra' and 'Volkamer'. The lowest yield was obtained from 'Carrizo'. Citrumelo 'Swingle', SxE, SxJ and 'Volkamer' obtained plants of 'Arrayana' tangerine with less height and volume than 'Cleopatra'; the best productive efficiency was obtained by SxJ followed by citrumelo 'Swingle', SxE (no statistical differences) markedly higher than 'Cleopatra' and 'Carrizo'. Citrumelo 'Swingle' produced 2,438 kg/plant in 11 pickings overpassing SxE by 1,776.6 kg of fruit per plant, 'Volkamer' (1,572.99 kg/plant) and SxJ (1,498.95 kg/ plant). Citrumelo 'Swingle' outyielded 'Cleopatra' by more than 1 t per tree in cumulative yield of 11 pickings. All rootstocks showed good fruit quality for domestic market.
Effect of fertilization level on water use and production of corn (Zea mays L.) in a cereal producing area in Colombia - a modeling exercise using AquaCrop-FAO
Authors: García A. Javier , Fischer Gerhard , Riaño H. Nestor
Published: June 2017

The effect of the amount of fertilization applied to the corn variety 'ICA V-156' (white grain) was calibrated and validated with the simulator AquaCrop in Cerete (Cordoba, Colombia) at an altitude of 20 m. The fertilization level determined factors related to biomass production, the harvest index, yield and water use, and potential evapotranspiration (Eto). The basic information which calibrated and validated the model came from research conducted in different altitudes in maize growing areas in Colombia. Unexpectedly, the water shortages occurred during the growing season, which the modelling had not considered. Levels of 90 to 60% of fertilization were applied to the crop according to the analysis of the evaluated soil. The information was subjected to an analysis of variance; the results showed that the level of fertilization affected the formation of biomass, harvest index and yield, as well as, the use of water during the growing season. The ETo values were extreme at 0.9 and 7.3 mm day-1. Likewise the total biomass production was 4.64% less at the level of 90 and 25.04% less at 60% fertilization, as compared to the biomass measurements in the field. Similarly, the harvest index was 32.3 and 29.8% for the 90 and 60% levels of fertilization, respectively; on the other hand the grain yield was not affected by the highest level (90%), whereas when the reduction in fertilization was 40%, a decrease of 14.335% in the grain yield was obtained. In addition, per m3 of water 18.87 and 23.02 kg of grain for the fertilization levels of 60 and 90% were formed, respectively.
Diagnóstico de la colección de escarabajos coprófagos (scarabaeidae: scarabaeinae) del Museo Entomológico Francisco Luis Gallego, Universidad Nacional de Colombia, sede Medellín
Authors: Martinez-Revelo Diego Esteban , Medina-Uribe Claudia Alejandra
Published: June 2017

Se presenta el diagnóstico del estado de  organización y conservación de la colección de escarabajos coprófagos (Scarabaeidae: Scarabaeinae) del Museo Entomológico Francisco Luis Gallego, de acuerdo con los diferentes niveles de curaduría del Índice de Salud de Colecciones (ISC). Se evaluaron 2405 especímenes con el fin de obtener información sobre el perfil de organización de la colección y las prioridades de gestión de la misma. El mayor porcentaje de especímenes se encontraron en los niveles dos (30.6%): ausencia de un proceso curatorial adecuado; y cinco (30.2%): curaduría completa, pero sin nomenclatura taxonómica actualizada. El índice de salud muestra que el 68.9% de la colección requiere actividades curatoriales. Las prioridades de manejo se enfocan en los niveles dos y tres, referentes a la organización física y accesibilidad al material por especialistas. Los resultados sugieren la necesidad de aumentar esfuerzos en el procesamiento taxonómico y visita de especialistas. Además es urgente catalogar, sistematizar e incorporar especímenes en la colección taxonómica central.
A gastrointestinalis lipomákról három operált esetünk kapcsán

Absztrakt

A lipomák az emésztőtraktusban ritkán fordulnak elő, leggyakrabban a subcutisban
találhatók. Általában nem okoznak panaszt, eltávolításra csak a tünetekkel járó
(vérzés, passzázszavar) lipomák kerülnek. Három, gastrointestinalis lipoma miatt
sikerrel operált betegünk esetét mutatjuk be: egy duodenalis (a bulbusból 4
cm-es lipomát enucleáltunk), egy vékonybél (intussusceptiót okozó lipoma az
ileumban; a bizonytalan makroszkópos kép miatt szegmentreszekciót végeztünk),
illetve egy vastagbéllipoma (47 cm-re az anustól elhelyezkedő, időszakos
elzáródást okozó nyeles lipomát colotomiából távolítottunk el).
Benignus ovariumtumorok okozta akut hasi kórképek

Absztrakt

Az akut has életet veszélyeztető állapot, amelynek azonnali helyes megítélése,
diagnózisa és kezelése mind a mai napig komoly kihívást jelent a műtéti
szakmában. A szerzők célul tűzték ki négy akut beteg diagnosztikai nehézséget
okozó kórképének a bemutatását, amiket nagyméretű benignus ovariumtumorok
okoztak. A benignus ovariumtumorok döntő többsége véletlenül kerül felismerésre,
például más okból elvégzett kismedencei fizikális vagy képalkotó vizsgálat,
egyéb okból végzett hasi műtétek során. Gyakran akut hasi tüneteket okoznak. A
kórtörténet, a fizikális vizsgálat és a képalkotó eljárások eredményei sem
vezetnek el mindig a pontos diagnózishoz. A szerzők a hasi feltárás során
jutottak el a betegség pontos felismeréséhez, s ez után tudták a megfelelő
műtétet elvégezni. A műtétet követően mind a négy beteg gyógyultan távozott a
kórházból.

A Hartmann-műtétet eredetileg a rectosigmoideum tumoros betegségeinek kezelésére
alkalmazták. Az utóbbi években a bal colonfél gyulladás okozta szövődmények,
tumoros bélelzáródás, perforáció, reszekciót követő varratelégtelenség esetén,
továbbá trauma okozta bélsérülés sürgős ellátására alkalmazzák, ha az
anasztomózis készítése kockázatos. A későbbi gastrointestinalis tractus
folytonosságának helyreállítása lehetséges hagyományos vagy laparoscopos úton.
Ez utóbbi technikával végzett műtéttel kapcsolatos tapasztalatainkat mutatjuk
be, összehasonlítva eredményeinket a hagyományos műtéti megoldással.

Az emlő-helyreállító műtétek eredményei a betegek számára nem mindig kielégítőek.
A latissimus dorsi izomlebennyel végzett helyreállító műtét megfelelő lehetőség,
és endoszkópos preparálás mellett a háti heg is elkerülhető. A hónaljban ejtett
egyetlen metszésen keresztül a bőrmegtartó mastectomia és a
sentinelnyirokcsomó-eltávolítás vagy az axillaris lymphadenectomia is
elvégezhető. Az azonnali emlőrekonstrukcióhoz egyes esetekben a latissimus dorsi
izomlebeny használható fel, amely endoszkóposan asszisztáltan ebből a metszésből
kipreparálható. A bemutatott beteg az esztétikai és a funkcionális eredménnyel
is elégedett volt, a mell alakjának megőrzése és a háti heg mellőzésének
köszönhetően.

A gastrointestinális vérzés oka lehet a gyomor antralis régiójának és néha a
cardiatájéknak a kóros értágulata. Első leírója a múlt század 50-es éveinek
elején a GAVE (Gastric Antral Vascular Ectasia) névvel illette, miután ekkor még
a hasonló jelenséget a cardiatájon nem regisztrálták. Negyed századdal később –
néhány eset közlése kapcsán – egy szellemes belgyógyász ragasztotta rá a
görögdinnye (watermelon) elnevezést, minthogy a makroszkópos kép az említett
gyümölcs „héjára hajaz”. A raritásnak számító kórkép súlyos társ betegségekkel
terhelt betegünknél jelentkezett.

Interesses financeiros e captura do Estado no Brasil
Authors: IANONI MARCUS
Published: June 2017

RESUMO O trabalho explora a avaliação de (Bresser-Pereira, 2007) de que a política macroeconômica brasileira exprime a captura do Estado por uma coalizão de interesses rentistas e financistas, que também influencia a regulação financeira. Para tanto, analisa duas agências de relacionamento com investidores, do Banco Central e do Tesouro Nacional, e uma agência de promoção de investimentos formada por reguladores e regulados. Argumenta que essas agências estreitam a comunicação e canais de formulação de políticas entre reguladores e regulados; atestam a influência das instituições financeiras nas decisões de políticas públicas; e corporificam convergência de interesses entre investidores financeiros e Estado. Conclui avaliando que a tesa da captura da política macroeconômica é plausível e deve ser pesquisada de modo sistêmico.

Authors: CINTRA MARCOS ANTONIO MACEDO , PINTO EDUARDO COSTA
Published: June 2017

RESUMO Este artigo examina as atuais estratégias de desenvolvimento da China, que enfrenta um período de transição interna - em virtude das contradições do seu regime de crescimento -, e redefinições das relações com o restante do mundo que vem desencadeando um processo de reconfiguração da ordem mundial (transição internacional). Dois dos principais eixos dessa estratégia chinesa são a ampliação do uso do renminbi no âmbito mundial e a internacionalização do capital chinês por meio dos megaprojetos de infraestrutura, notadamente no entorno asiático.
O estado pastor e os incentivos tributários no setor automotivo
Authors: SCHAPIRO MARIO G.
Published: June 2017

RESUMO Este trabalho tem o objetivo de descrever os incentivos tributários que foram implementados nas últimas décadas com vistas a promover a competitividade do setor automotivo. Além disso, pretende qualificar o papel que o Estado tem desempenhado neste segmento. Baseado na literatura de regulação econômica e de economia política, o trabalho sugere que as políticas tributárias adotadas para o setor têm conformado mais um Estado “pastor” que um Estado “parteiro”. Isto é, os incentivos tributários têm se orientado para corrigir falhas sistêmicas e assim proteger um segmento já estabelecido e não propriamente para estimular a formação de novas competências econômicas.
