Diseño de Tareas de Aprendizaje Matemático con Geogebra: Mecanismos Articulados
Authors: Campos Nava Marcos , Torres Rodríguez Agustín Alfredo
Published: January 2018

Las Tareas de Aprendizaje Matemático (TAM) son el principal medio a través del cual el profesor puede propiciar que sus estudiantes construyan los conceptos matemáticos motivo de estudio y de discusión. No basta dar el enunciado de un problema para afirmar que se tiene una Tarea diseñada; tampoco basta únicamente diseñar la actividad para considerar que será exitosa. Por otro lado, el uso de tecnologías digitales en la clase de matemáticas, puede ser un elemento favorable para que el profesor diseñe tareas que le permitan articular las relaciones existentes entre diferentes conceptos matemáticos, además de promover el entendimiento de diversas ideas. En este sentido, se propone una TAM basada en el mecanismo de pistón o también conocido como manivela-deslizador, que al ser abordada con el uso de un sistema de geometría dinámica (SGD) como Geogebra, puede estimular el logro de la articulación de conceptos e ideas y un mayor entendimiento en la clase de matemáticas.
Comparison of Basal Serum Testosterone Levels between Male Athletes and Martial Artists
Authors: Arjona-Luna Roberto
Published: January 2018

There are reports about the relationship between testosterone levels and aggressiveness in animals and humans. The practice of martial arts requires high levels of pain tolerance, fear control and of course, enough aggressiveness to overcome psychological and biological stress. Therefore, the objective of the present study was to identify the relationship between basal testosterone levels and martial arts practice by comparing total serum testosterone values between male athletes and martial artists. In this cross-sectional study, the total testosterone between a control group of 15 male athletes and 15 male martial artists was compared. The participants had the following inclusion criteria: healthy men between 18 and 35 years old, not obese, with at least 1 year of continuous training, 3 to 5 sessions per week with a duration from 60 to 90 min at a moderate to high intensity, non smokers, alcohol free, and free from exogenous testosterone or testosterone precursors. Blood samples were recolected between 8:00 to 10:00 am and the laboratory results were obtained by chemiluminescence. The testosterone levels mean of the martial artist's group was 6.44 (±1.17) ng/mL and the athlete's control group had a mean of 6.09 (±1.32) ng/mL. Comparing values with the Student´s t-test showed no statistically significant difference, with a p value of 0.45. There is no significant difference of basal total testosterone levels between male martial artists and athletes, and it seems there is no direct relationship between testosterone levels and martial arts practice. Further investigation on the physiologic responses produced by the practice of combat sports is a growing necessity.

Authors: Savu Vasile-Cătălin , Moisescu Petronel
Published: January 2018

In the opinion of the specialists, the technique was left behind by the speed of the game and a reassessment and a readaptation of the methods and operational means must be initiated from children and Juniors stage, in order to recreate the way and access to great performance of new exceptional generations in football. On analyzing the technique of the game, we will find totally different evolutions compared to the past, when it was much more static and we do not mean the senior teams, but to groups of juniors who are starting to play football for the first time on a field with specific dimensions following the laws of the game. Currently, the technique is expressed through velocity, in constant motion, with almost permanent opposition from the opponent, having reached unimaginable values in the recent past. Technique is now complex, rapid, adequate to the varied game situations and with a permanent opposition.

Study Regarding the Professional Sports Practice Possibilities of the Slanic Moldova Area, in Bacau County
Authors: Ababei Radu
Published: January 2018

This study highlights both the financial aspects necessary to support sports, and the biochemical aspects related to exercising in a controlled environment, under conditions of constant temperature and humidity, and saline air. The paper also proposes the construction of a sports training base in a part of the Târgu Ocna Salt Mine, which could have beneficial effects regarding both sports results and the revitalization of tourism in that area. The study has emphasized also the fact that there is an insufficient promotion of the so-called "sports tourism", which leads to an insufficient occupation of the accommodation spaces of the resort. There is a need for a database that would be made available to the sports clubs, for them to be able make the best choice to conduct their centralized training.

Mellifluent Sexuality: Female Intimacy in Ann Radcliffe’s The Romance of the Forest
Authors: Chow Jeremy
Published: January 2018

Pamphlets like Onania (1716), whose rate of reprinting exploded during the eighteenth century, became docents for ironically teaching and demonstrating erotic pleasures to readers, rather than expurgating them, as intended. As a result, the possibilities for pleasure reading were varied and many. I offer Ann Radcliffe’s novel The Romance of the Forest (1791), as an extension of those autoerotic reading pleasures for an eighteenth-century audience. Radcliffe’s novel veils the possibility of a masturbatory narrative with music and instrumentality. The lute, an instrument with diverse and erotic resonances in the eighteenth century, mediates these practices for Radcliffe’s two heroines. In meditating on the lute’s depiction, I trace the early modern history of the lute in literature and art, reflect on its connections to embodiment and erotic performance, and consider the ways musical performance becomes a site of female intimacy and pleasure, which complicates readings of public and private spaces. For Clara and Adeline, the autoerotic lute enables the blossoming of transgressive sexuality, despite the heteronormativity offered by the novel’s ending.

Microstructure and mechanical properties of friction welded AISI 1040/AISI 304L steels before and after electrochemical corrosion
Authors: Sarsilmaz Furkan , Kırık İhsan , Ozdemir Niyazi
Published: January 2018

The aim of the present study is to investigate the effect of welding parameters both on the electrochemical corrosion behavior and tensile strength of pre- and post-electrochemical corrosion of friction welded dissimilar steels. The microstructural changes of AISI 1040/AISI 304L friction welded couples and also parent materials were analyzed by using scanning electron microscopy. The electrochemical behaviors of AISI1040/AISI304L joints were comparatively investigated by potentiodynamic polarization curve test and by electrochemical impedance spectra. Moreover, tensile strength experiments were carried out determining the behavior of friction welded joints of pre- and post-electrochemical corrosion and results indicated that the maximum tensile test value of the dissimilar welded pre-electrochemical corrosion was higher than those of post-electrochemical corrosion and was also very close to AISI 1040 parent material value.
Preparation and characterization of Kevlar/glass fiber laminates with a nanoclay enhanced epoxy matrix
Authors: Vivekanandhan Chinnasamy , Sampath Pavayee Subramani , Sagadevan Suresh
Published: January 2018

Improvement of existing composite material to obtain new composite materials is the real challenge for most of the materials engineers. So, there are huge research endeavors emerging in the field of composites to grow new materials with upgraded mechanical, electrical and thermal properties. Among these, fiber reinforced polymer composites are the most charming as a result of their sufficient utilization in different applications which incorporates numerous mechanical, automotive and structural components. The present study investigates the mechanical characteristics of a Kevlar/glass fiber reinforced with Cloisite 30B nanoclay. Kevlar fibers have been widely used as impact-resistant reinforcement in composite materials. However, there are very few works about the effects of nanoclays on the impact strength of Kevlar/glass laminates. Nanoclay Cloisite 30B (2 wt.-%) was dispersed in the epoxy system. Such laminates manufactured with epoxy resin filled by 2 wt.-% of nanoclay showed the best performance in terms of elastic recuperation and penetration threshold. The opposite tendency was observed for the displacement at peak load. However, marginal benefits can be found when compared with the results obtained for laminates filled by 2 wt.% nanoclay. Kevlar/glass fibers were reinforced with different particulate fractions of chosen nanoclay and the specimens were investigated regarding mechanical properties such as tensile, impact and flexural strength.

Published: January 2018

The most common primary cardiac tumor is myxoma, typically originating in the left atrium. Emboli to the central nervous system can cause cerebral infarction or, rarely, seed tumor growth within vessel walls, causing myxomatous aneurysms. Fewer than 60 myxomatous aneurysms have been reported, including 2 cases in children. Here, the authors describe 2 different growing myxomatous aneurysms in a child successfully managed using a combined multidisciplinary approach. A 12-year-old boy developed a sudden headache, diplopia, gait instability, and speech difficulty. Magnetic resonance imaging revealed a left parietal hemorrhage and multifocal cerebral infarction, suspicious for an embolic etiology. A cardiac myxoma was identified in the left atrium and resected. Follow-up cranial vasculature imaging demonstrated multiple intracranial myxomatous aneurysms. These lesions were followed up, and serial imaging identified marked growth of 2 of them (right occipital and left parietal), prompting invasive intervention. The deep occipital lesion was better suited to endovascular treatment, while the superficial parietal lesion was amenable to resection. The patient underwent embolization of an enlarging fusiform aneurysm of the distal right posterior cerebral artery, followed by a left parietal craniotomy for a lesion of the distal left middle cerebral artery. Both procedures were performed without complications and achieved successful obliteration of the lesions, as confirmed by catheter angiography at the 30-month follow-up. To the authors’ knowledge, this report illustrates the first combined endovascular and open surgical treatment of 2 myxomatous aneurysms in a single patient. While acknowledging the rarity of this condition, this report illustrates the clinical manifestations and treatment challenges posed by myxoma and details a successful strategy that could be employed in similar scenarios.
'Few Commodities are More Hazardous': Australian Live Animal Export, 1788-1880
Authors: Cushing Nancy
Published: January 2018

Live animal export has a long history but it is rarely considered in the vigorous contemporary debates surrounding the practice. This article explores the origins, extent and nature of the trade in livestock, primarily sheep and cattle, conducted out of Britain's first Australian colony, New South Wales, between 1788 and 1880. Drawing upon contemporary accounts and official statistics related to the trade, it contributes to the literature on human-animal relations by exploring the experience of animals during live export and the effect of the trade on attitudes to meat consumption. By subjecting animals to long sea voyages for the purposes of breeding or consumption, live export in the colonial period laid the groundwork for the commodification of animals used for food and the industrialisation of meat production in the twentieth century.
Climate, Conflict and Society: Changing Responses to Weather Extremes in Nineteenth Century Zululand

Published: January 2018

Changing climates affect human societies differently depending on societal structures, cultural perceptions and their relative vulnerability and resilience. In this study, we explore the complex relationship between climate, conflict and society in nineteenth century Zululand. The paper first reviews current debates surrounding the links between climatic change, societal transformation and the rise of the Zulu Kingdom from the late-eighteenth to early-nineteenth centuries. It then considers new empirical evidence relating to conflict and socio-economic changes at a local scale in Zululand from the early-mid-nineteenth century onwards, using a combination of unpublished archival materials written by missionaries and other observers, together with oral histories and traditions. Our analysis highlights how changing precipitation patterns, especially towards drier conditions, may have contributed to changes in societal responses, including dominant narratives about rain-control, the migration and dissolution of society, and conflicts and unrest. We suggest that temporal differences in these responses were contingent upon the role of leaders, power structures, and the willingness and ability of leaders to yield this power. The case of nineteenth century Zululand exemplifies the complexity of environment-society interactions, and strengthens the call for a thorough scrutiny of the narratives of social unrest in specific socio-cultural contexts.
Science, Markets and Power: Adolf Severin Jensen in the Debate over Greenland's Fisheries Development during the Early Twentieth Century
Authors: Priebe Janina
Published: January 2018

As a fisheries consultant to the colonial administration, Adolf Severin Jensen (1866-1953) followed, and was an active commentator on, all stages of the commercialisation of Greenland's fishing industry - from its early assessment shortly after 1900 to the sector's peak in the 1930s, and the first signs of a changing trend in the 1940s. This paper puts Jensen's perceptions of Greenlandic fisheries in dialogue with the ideas of scientific rationalisation, economic efficiency and colonial power. The accounts of the fisheries scientist offer a glimpse into the complicated interplay of applied science in natural resource exploitation and state interests at the turn of the twentieth century. His research agenda was coined by the goals of fisheries science to connect knowledge production to markets. However, Jensen's findings also merged with Denmark's aim to secure its colonial authority in Greenland and to exert effective power over both resources and people.
'Racy of the Soil': Ian Mudie, Right-Wing Nationalism, and the South Australian Soil Erosion Crisis
Authors: Regan Jayne
Published: January 2018

Ian Mudie was an Adelaide-based freelance journalist, short story and history writer, and most notably a passionate and political poet. During the 1930s and 1940s the degradation of South Australian agricultural and pastoral soil inspired Mudie to evoke soil in his poetry. Soil also proved a useful metaphor which Mudie could deploy in aid of his right-wing political stance. Critics and historians have described Mudie either as a 'nationalist or propagandist' and a 'hectoring' nationalist, or, alternatively, as an early conservationist and even a 'proto ecologist'; none address the intersection of environmental concern and right-wing nationalism in his poetry and politics. This article will interrogate the relationship between these two ideologies in Mudie's work. Despite echoes of Nazi 'blood and soil' ideology, Mudie's soil erosion poetry was primarily the product of his settler imagination, and resonated with 'cultural nationalists' in the Australian literary community.
Quiescent and Active Phases in Be Stars: A WISE Snapshot of Young Galactic Open Clusters

Published: January 2018

Through the modeling of near-infrared photometry of star-plus disk systems with the codes bedisk/beray, we successfully describe the Wide-Field Infrared Survey Explorer (WISE) photometric characteristics of Be stars in five young open clusters, NGC 663, NGC 869, NGC 884, NGC 3766, and NGC 4755, broadly studied in the literature. WISE photometry allows previously known Be stars to be detected and to find new Be candidates which could be confirmed spectroscopically. The location of Be stars in the WISE color–magnitude diagram, separates them in two groups; active (Be stars hosting a developed circumstellar disk) and quiescent objects (Be stars in a diskless phase), and this way, we can explore how often stars are observed in these different stages. The variability observed in most active variable Be stars is compatible with a disk dissipation phase. We find that 50% of Be stars in the studied open clusters are in an active phase. We can interpret this as Be stars having a developed circumstellar disk one-half of the time. The location of Be stars with a developed disk in the color–magnitude diagram require mass loss rates in agreement with values recently reported in the literature. For these objects, we expect to have a tight relation between the equivalent width of the Hα line and the mass of the disk, if the inclination is known. Also, near-infrared photometry of Be stars in stellar clusters has the potential of being useful to test whether there is a preferential viewing angle.

The Carnegie–Chicago Hubble Program (CCHP) seeks to anchor the distance scale of Type Ia supernovae via the Tip of the Red Giant Branch (TRGB) method. Based on deep Hubble Space Telescope ACS/WFC imaging, we present an analysis of the TRGB for the metal-poor halo of NGC 1365, a giant spiral galaxy in the Fornax cluster that was host to the Type Ia supernova SN 2012fr. We have measured the extinction-corrected TRGB magnitude of NGC 1365 to be F814W = 27.34 ± 0.03stat ± 0.04sys mag. In advance of future direct calibration by Gaia, we adopt a provisional I-band TRGB luminosity set at the Large Magellanic Cloud and find a true distance modulus μ
0 = 31.29 ± 0.04stat ± 0.06sys mag or D = 18.1 ± 0.3stat ± 0.5sys Mpc. This measurement is in excellent agreement with recent Cepheid-based distances to NGC 1365 and reveals no significant difference in the distances derived from stars of Populations I and II for this galaxy. We revisit the error budget for the CCHP path to the Hubble constant based on the analysis presented here, i.e., that for one of the most distant Type Ia supernova hosts within our Program, and find that a 2.5% measurement is feasible with the current sample of galaxies and TRGB absolute calibration.

We report the discovery of a substellar-mass co-moving companion to 2MASS J22501512+2325342, an M3 candidate member of the young (130–200 Myr) AB Doradus Moving Group (ABDMG). This L3 β companion was discovered in a 2MASS search for companions at separations of 3″–18″ from a list of 2812 stars suspected to be young (≲500 Myr) in the literature, and was confirmed with follow-up astrometry and spectroscopy. Evolutionary models yield a companion mass of

at the age of ABDMG. The 2MASS J22501512+2325342 AB system appears to be a spatial outlier to the bulk of ABDMG members, similarly to the young 2MASS J22362452+4751425 AB system. Future searches for young objects around these two systems would make it possible to determine whether they are part of a spatial extension of the known ABDMG distribution.
Devenir parent après un placement dans l’enfance

Published: January 2018

Notre propos vise à encourager les professionnels engagés auprès des familles dont un enfant est placé, à inscrire leurs interventions dans une temporalité, ces enfants dits « placés » étant potentiellement de futurs parents. Ainsi, le regard se portera d’emblée sur leur filiation, dimension transgénérationnelle essentielle du devenir. Les contextes de placement, souvent traumatiques, nécessitent des interventions éducatives et psychothérapeutiques susceptibles d’aménager le quotidien des enfants tout en les aidant à transformer leur expérience douloureuse. À travers une illustration clinique étayée par différents médiateurs de rencontre, nous mettrons en évidence combien il est important de mettre la question des origines doublée de l’ancrage filiatif et affiliatif au travail. L’utilisation des génogrammes avec les familles, les parents et les professionnels apparaît être un outil pertinent. Le but étant que ces enfants puissent construire de manière créative leur future parentalité, tout en veillant à clarifier et à assouplir la représentation de leur inscription filiative.

Comment l’expérience du placement participe-t-elle à construire le mineur et la famille ? À partir du récit d’une mineure, de sa mère et de l’éducatrice référente, l’article cherche à situer l’expérience du placement dans la trajectoire sociale du mineur, dans la trajectoire familiale et dans les rapports de la famille avec les services sociaux. Trois femmes, trois voix pour dire des liens, des résistances, des répétitions générationnelles… Confrontés à une même expérience, trois regards, trois points de vue différents permettront d’appréhender la complexité des constructions individuelles et familiales dans ses entrecroisements avec le système de protection de l’enfance.
Comme une danse à plusieurs
Authors: Verbist Yolande
Published: January 2018

Enfants, familles, institutions éducatives, thérapeutiques et scolaires ont parfois bien du mal à s’accorder. Les situations que vivent les enfants interrogent notre rapport à l’idéal. Pour que les placements créent un mouvement, une ouverture, il nous paraît nécessaire que nos langages, nos diagnostics, nos mythes, nos interventions s’attellent à créer des histoires communes, qu’il se crée une forme de co-élaboration. Le nombre d’intervenants rassemblés autour de situations souvent complexes, permet qu’un espace de jeu s’ouvre, que des alliances se nouent et se dénouent. Si les partenaires s’engagent dans un processus de réassurance, de reconnaissance réciproque et luttent contre les disqualifications, ce jeu tend à rendre chacun plus compétent. Ces histoires communes permettent alors peut-être un dé-placement.

L’invention de la formation des entraîneurs (1941-1991) : entre construction identitaire professionnelle et pérennisation des « valeurs » du football
Authors: Grün Laurent
Published: January 2018

Le diplôme d’entraîneur professionnel de football, créé en 1942, pose les bases d’une formation qui constitue aussitôt un espace d’identification fort, en permettant à ses lauréats de cultiver la pratique de l’entre-soi ainsi que la volonté de défendre leur profession. Le stage d’entraîneurs fournit également un cadre où se forge une culture commune, qui véhicule des valeurs liées au travail, à l’effort, à l’abnégation. Si les entraîneurs bénéficient de contenus techniques, tactiques et pédagogiques, en réalité, on leur inculque des comportements et des attitudes durables, qui marqueront plusieurs générations successives. Sous la férule de dirigeants comme Georges Boulogne, les futurs lauréats subissent en effet une rigoureuse imprégnation à des attitudes de soumission et de conformité à ces valeurs propres à « la famille » des entraîneurs. En 1947, la création de l’Amicale des entraîneurs, concomitante au stage national d’entraîneurs, contribue à la mise en place, puis à la pérennisation du caractère endogame du recrutement.

Authors: Wood Edward H. , Whitted Ryan J. , Stone Thomas W. , Isernhagen Ricky D. , Wood William J. , Holcomb Diana M. , Kitchens John W.
Published: January 2018

BACKGROUND AND OBJECTIVE:

Ranibizumab (Lucentis; Genentech, South San Francisco, CA) is used off-label for the treatment of choroidal neovascularization secondary to ocular histoplasmosis syndrome (OHS). This study prospectively evaluates the safety and efficacy of two treatment paradigms utilizing ranibizumab 0.5 mg: one or three initial injections followed by monthly visits with PRN treatment through Month 12.

PATIENTS AND METHODS:

In this prospective, open-label study, 21 subjects were evaluated monthly and retreated during the pro re nata treatment phase if specific criteria were met, including loss of vision, increase in subretinal fluid, or hemorrhage. Adverse events, best-corrected visual acuity (BCVA), and central subfield retinal thickness (CST) were evaluated.

RESULTS:

No adverse events were observed. Mean BCVA improved in both groups by approximately 2 lines, and mean CST decreased by approximately 100 μm at month 12. The number of injections was the same (5.7 and 5.8 injections).

CONCLUSION:

Results suggest that ranibizumab is safe and efficacious for treatment of CNV secondary to OHS.

Authors: Dirani Ali , Ciongoli Marina Ravagnani , Lesk Mark R. , Rezende Flavio
Published: January 2018

BACKGROUND AND OBJECTIVE:

Pars plana glaucoma drainage implant (GDI) occlusion is mainly related to entrapment of residual anterior vitreous gel in the implant. The aim of the present report is to describe a new surgical technique to induce pneumatic anterior hyaloid detachment in eyes with GDI.

PATIENTS AND METHODS:

This is a description of the surgical technique used to induce pneumatic anterior hyaloid detachment.

RESULTS:

The technique was used in two cases. The first patient had secondary Ahmed valve (New World Medical, Rancho Cucamonga, CA) obstruction secondary to anterior vitreous entrapment; the second patient had neovascular glaucoma secondary to proliferative diabetic retinopathy and underwent pars plana GDI implantation.

CONCLUSION:

Endoscopy-assisted anterior hyaloid detachment allows for complete removal of anterior hyaloid and decreases the risk of secondary implant obstruction.

V prispevku je obravnavan odsev verovanj in vraževerja ter čarovništva in magije v povedkah, zbranih v vzhodnodolenjski občini Šentrupert. Vsaj za posameznike je bilo do nedavna čarovništvo nekaj samo po sebi umevnega, seveda slabega, in je imelo svoj protipol v posameznikih, ki so negativne posledice znali odpraviti. Dalo se je ukaniti tudi zelo personificiranega hudiča, medtem ko se je zaščita proti mori že izgubila iz ljudskega spomina. Sproti je opozarjeno na podobnosti in razlike z ugotovitvami sicer širše raziskave vaškega čarovništva v vzhodni Sloveniji (Mencej 2006).

This paper is a discussion of the reflections of beliefs, superstitions, witchcraft and magic in folk tales gathered in the eastern Dolenjska municipality of Šentrupert. Until recently, at least some individuals there believed in witchcraft as something self-evident and malevolent as well as in the existence of persons who knew how to eliminate its negative consequences. This included tricking the highly personified ‘devil’(hudič), while protection against ‘(night)mare’ (mora) has already disappeared from folk memory. The author also points out the similarities and differences to findings of broader research on village witchcraft in eastern Slovenia (Mencej 2006).

Cette communication est une étude de cas d’un jeu « pervasif » sur mobile nommé Ingress. Nous montrerons comment cette pratique ludique transforme, à des degrés divers, l’organisation des déplacements quotidiens, tout en reposant sur différents formats d’interactions sociales (en ligne, en coprésence). Cette épaisseur collaborative est souvent vectrice de communication interpersonnelle et de sociabilité entre les membres de la communauté qui oriente également la mobilité. Initialement ethnographique, cette étude fut également l’occasion de développer de nombreuses méthodes pour comprendre les mobilités ludiques et l’interconnaissance, depuis l’analyse des activités dans des environnements naturels à l’étude statistique de millions de logs. Une attention constante sera réservée à ces méthodes dans l’optique de montrer à la fois les résultats et les moyens par lesquels ils ont été produits.
Wet Powder Metallurgy Process for Dispersing Carbon Nanotubes and Fabricating Magnesium Composite

Published: January 2018

A wet powder metallurgy (WPM) process was developed to disperse carbon nanotubes (CNTs), and to fabricate the CNTs reinforced Mg matrix (CNTs/Mg) composite. The dispersion effect of CNTs were evaluated by field emission scanning electron microscopy (FE-SEM), dynamic light scattering (DLS) and high-resolution transmission electron microscopy (HR-TEM), respectively. Results showed that the CNTs were homogeneously dispersed on the surface of Mg powder. Adequate bonding and good interfacial interaction between the CNTs and Mg matrix contributed to the efficient load transferring from the CNTs to Mg matrix under a mechanical force. Furthermore, no brittle MgO was formed on the surface and it was beneficial to improving the adhesion of the CNTs to Mg matrix. With 0.5 wt.% CNTs addition, the CNTs/Mg composite experienced remarkable enhancements in tensile stress of 28% and Young’s modulus of 24%. The reasons responsible for these enhancements are suggested as the effective dispersion of the CNTs and the good interface bonding between the CNTs and Mg matrix.

Agonists to the TNF/TNFR costimulatory receptors CD134 (OX40) and CD137 (4-1BB) elicit antitumor immunity. Dual costimulation with anti-CD134 plus anti-CD137 is particularly potent because it programs cytotoxic potential in CD8+ and CD4+ T cells. Cytotoxicity in dual-costimulated CD4 T cells depends on the T-box transcription factor eomesodermin (Eomes), which we report is induced via a mechanism that does not rely on IL-2, in contrast to CD8+ CTL, but rather depends on the CD8 T cell lineage commitment transcription factor Runx3, which supports Eomes expression in mature CD8+ CTLs. Further, Eomes and Runx3 were indispensable for dual-costimulated CD4 T cells to mediate antitumor activity in an aggressive melanoma model. Runx3 is also known to be expressed in standard CD4 Th1 cells where it fosters IFN-γ expression; however, the CD4 T cell lineage commitment factor ThPOK represses transcription of Eomes and other CD8 lineage genes, such as Cd8a. Hence, CD4 T cells can differentiate into Eomes+ cytotoxic CD4+CD8+ double-positive T cells by terminating ThPOK expression. In contrast, dual-costimulated CD4 T cells express Eomes, despite the continued expression of ThPOK and the absence of CD8α, indicating that Eomes is selectively released from ThPOK repression. Finally, although Eomes was induced by CD137 agonist, but not CD134 agonist, administered individually, CD137 agonist failed to induce CD134−/− CD4 T cells to express Eomes or Runx3, indicating that both costimulatory pathways are required for cytotoxic Th1 programming, even when only CD137 is intentionally engaged with a therapeutic agonist.

In obesity, IL-13 overcomes insulin resistance by promoting anti-inflammatory macrophage differentiation in adipose tissue. Endogenous IL-13 levels can be modulated by the IL-13 decoy receptor, IL-13Rα2, which inactivates and depletes the cytokine. In this study, we show that IL-13Rα2 is markedly elevated in adipose tissues of obese mice. Mice deficient in IL-13Rα2 had high expression of IL-13 response markers in adipose tissue, consistent with increased IL-13 activity at baseline. Moreover, exposure to the type 2 cytokine-inducing alarmin, IL-33, enhanced serum and tissue IL-13 concentrations and elevated tissue eosinophils, macrophages, and type 2 innate lymphoid cells. IL-33 also reduced body weight, fat mass, and fasting blood glucose levels. Strikingly, however, the IL-33–induced protection was greater in IL-13Rα2–deficient mice compared with wild-type littermates, and these changes were largely attenuated in mice lacking IL-13. Although IL-33 administration improved the metabolic profile in the context of a high fat diet, it also resulted in diarrhea and perianal irritation, which was enhanced in the IL-13Rα2–deficient mice. Weight loss in this group was associated with reduced food intake, which was likely related to the gastrointestinal effects. These findings outline both potentially advantageous and deleterious effects of a type 2–skewed immune response under conditions of metabolic stress, and identify IL-13Rα2 as a critical checkpoint in adipose tissues that limits the protective effects of the IL-33/IL-13 axis in obesity.

Primary adrenal lymphoma (PAL) is a relatively rare disease entity with only fewer than 200 cases reported till date. PAL frequently presents with bilateral adrenal involvement and shows male preponderance. We here present a case of PAL in a 65-year-old female with a relatively uncommon unilateral adrenal involvement. The present case depicts that 18F-fluorodeoxyglucose positron emission tomography/computed tomography had decisive role in the treatment management of this patient suggesting its potential utility in the management of this rare disease.

Aim: Data regarding the optimal management of metastatic anorectal melanoma (mARM) is scarce. The primary aim was to evaluate the potential benefits of systemic therapy in mARM. Materials and Methods: This is a retrospective analysis of all mARM who presented between July 2013 and June 2015 at the Department of GI Medical Oncology, Tata Memorial Hospital. Results: Of a total of 37 patients, twelve patients were planned for best supportive care (BSC) only while the remaining 25 patients received systemic therapy. The median overall survival (OS) for the whole cohort was 27 weeks. The OS was significantly better in patients who received first-line therapy as compared to those who were offered BSC (median OS: 14 vs. 33 weeks; P = 0.04). Patients with PS of 1 did significantly better than PS of 2 more (OS 70 vs. 17 weeks; P = 0.015). Conclusion: mARM should be offered chemotherapy, especially in good performance patients. Paclitaxel/Platinum or Capecitabine/Temozolomide regimens can be considered as the preferred regime in the resource-limited setting where immunotherapy may not be a feasible option.
Incidental detection of asymptomatic brain metastases on 18F-fluoride positron emission tomography/computed tomography and 68Ga DOTANOC positron emission tomography/computed tomography in a patient with concomitant breast carcinoma and a pancreatic neuroendocrine tumor

A 54-year-old female treated for locally advanced ductal breast carcinoma was also diagnosed with a pancreatic neuroendocrine tumour. A staging 68Ga DOTANOC positron emission tomography/computed tomography (PET/CT) demonstrated somatostatin receptor-positive foci within the brain parenchyma. A whole body 18F-fluoride PET/CT also demonstrated several foci of low-grade tracer uptake in the brain. Magnetic resonance imaging confirmed several cerebral and cerebellar metastases. This case highlights the need to be aware of each tumor's metastatic profile and the careful attention required for thoroughly evaluating imaging in the presence of multiple pathologies. Furthermore, such incidental findings can have significant treatment and prognostic implications.

The aim of our study was to correlate tumor uptake of 68Ga-DOTA-NOC positron emission tomography/computed tomography (PET/CT) with the pathological grade of neuroendocrine tumors (NETs). 68Ga-DOTA-NOC PET/CT examinations in 41 patients with histopathologically proven NETs were included in the study. Maximum standardized uptake value (SUVmax) and averaged SUV SUVmean of “main tumor lesions” were calculated for quantitative analyses after background subtraction. Uptake on main tumor lesions was compared and correlated with the tumor histological grade based on Ki-67 index and pathological differentiation. Classification was performed into three grades according to Ki-67 levels; low grade: Ki-67 <2, intermediate grade: Ki-67 3–20, and high grade: Ki-67 >20. Pathological differentiation was graded into well- and poorly differentiated groups. The values were compared and evaluated for correlation and agreement between the two parameters was performed. Our study revealed negatively fair agreement between SUVmax of tumor and Ki-67 index (r = −0.241) and negatively poor agreement between SUVmean of tumor and Ki-67 index (r = −0.094). SUVmax of low-grade, intermediate-grade, and high-grade Ki-67 index is 26.18 ± 14.56, 30.71 ± 24.44, and 6.60 ± 4.59, respectively. Meanwhile, SUVmean of low-grade, intermediate-grade, and high-grade Ki-67 is 8.92 ± 7.15, 9.09 ± 5.18, and 3.00 ± 1.38, respectively. As expected, there was statistically significant decreased SUVmax and SUVmean in high-grade tumors (poorly differentiated NETs) as compared with low- and intermediate-grade tumors (well-differentiated NETs). SUV of 68Ga-DOTA-NOC PET/CT is not correlated with histological grade of NETs. However, there was statistically significant decreased tumor uptake of 68Ga-DOTA-NOC in poorly differentiated NETs as compared with the well-differentiated group. As a result of this pilot study, we confirm that the lower tumor uptake of 68Ga-DOTA-NOC may be associated with aggressive behavior and may, therefore, result in poor prognosis.
