Abstract

Objective
Our aim was to quantify the individual contribution of prepregnancy (PP) fat-free mass (FFM), expressed as [PP-FFM index (PP-FFMI) = FFM (kg)/height (m2)], on markers of glucose homeostasis before and during pregnancy.

Methods
Body composition was assessed in 43 women before pregnancy using air-displacement plethysmography. Blood was drawn at PP and gestational weeks ∼8 and 30. Relationships between body composition (independent) variables and glucose homeostasis (dependent) variables were assessed using adjusted correlations and simple and multiple linear regression analyses.

Results
PP-FFMI was the strongest predictor of plasma insulin concentration [squared partial correlation (Pr2) = 17, P = 0.007] and homeostasis model assessment of insulin resistance (HOMA2-IR) (Pr2 = 16, P = 0.010). At gestation week 30, PP-FFMI and gestational weight gain (GWG) were the strongest predictors of insulin concentration (PP-FFMI: Pr2 = 20, P = 0.010; GWG: Pr2 = 12, P = 0.052) and HOMA2-IR (PP-FFMI: Pr2 = 19, P = 0.012; GWG: Pr2 = 13, P = 0.045). After accounting for PP fat mass index (PP-FMI), PP-FFMI and GWG were independently associated with first-phase insulin response (PP-FFMI: Pr2 = 20, P = 0.009; GWG: Pr2 = 15, P = 0.025) and second-phase insulin response (PP-FFMI: Pr2 = 19, P = 0.011; GWG: Pr2 = 17, P = 0.016). PP-FMI was the strongest predictor of an oral glucose tolerance test‒derived estimated metabolic clearance rate of glucose (PP-FMI: Pr2 = 14, P = 0.037) and estimated insulin sensitivity index (PP-FMI: Pr2 = 13, P = 0.047).

Conclusions
PP-FFMI was a predictor of markers of glucose homeostasis before and during pregnancy. Studies assessing the effect of skeletal muscle quality on metabolic regulation during pregnancy are warranted.
C. elegans PTEN and AMPK block neuroblast divisions by inhibiting a BMP-insulin-PP2A-MAPK pathway

ABSTRACT
Caenorhabditis elegans that hatch in the absence of food stop their postembryonic development in a process called L1 arrest. Intriguingly, we find that the postembryonic Q neuroblasts divide and migrate during L1 arrest in mutants that have lost the energy sensor AMP-activated protein kinase (AMPK) or the insulin/IGF-1 signaling (IIS) negative regulator DAF-18/PTEN. We report that DBL-1/BMP works upstream of IIS to promote agonistic insulin-like peptides during L1 arrest. However, the abnormal Q cell divisions that occur during L1 arrest use a novel branch of the IIS pathway that is independent of the terminal transcription factor DAF-16/FOXO. Using genetic epistasis and drug interactions we show that AMPK functions downstream of, or in parallel with DAF-18/PTEN and IIS to inhibit PP2A function. Further, we show that PP2A regulates the abnormal Q cell divisions by activating the MPK-1/ERK signaling pathway via LIN-45/RAF, independently of LET-60/RAS. PP2A acts as a tumor suppressor in many oncogenic signaling cascades. Our work demonstrates a new role for PP2A that is needed to induce neuroblast divisions during starvation and is regulated by both insulin and AMPK.

Published: November 2018

Introduction Percutaneous access and closure is commonly performed for patients undergoing endovascular aneurysm repair (EVAR). It has proven to be a safe and successful method of closure associated with fewer complications when compared with the traditional open technique. Fascial closure is an alternative technique that can be used for closure reducing the risks associated with the open technique. The aim of this study was to assess the safety and durability of fascial closure for failed percutaneous closure device following EVAR. Materials and methods Over a 12-month period, 49 patients who had undergone EVAR were identified via our EVAR register. Retrospective analysis of the clinical records was undertaken. We identified all the patients who had fascial closure of the groins following a failed percutaneous closure device. Patients had a computed tomography angiogram one month postoperatively, with duplex imaging and clinic follow-up three months later. Results Fascial closure was performed in 14 groins. It failed in three groins and these patients had traditional open repair. Fascial closure was successful in 11 groins (7 patients). Of these seven patients, one was female (6%). The mean age was 80 years (range 68–92 years). Two patients died and one was lost to follow-up. One pseudoaneurysms were seen on computed tomography angiogram, which was managed conservatively and had resolved on follow-up imaging. Conclusions Fascial closure is a very good alternative to open repair after failure of the closure device.
Auxiliary partial orthotopic liver transplantation for acute liver failure
Authors: Shrivastav M , Rammohan A , Reddy MS , Rela M 
Published: November 2018

Introduction Auxiliary partial orthotopic liver transplantation (APOLT) in acute liver failure acts as a bridge to native liver regeneration with potential for immunosuppression free survival. While technical concerns limit its universal acceptance, the indications in acute liver failure also need to be examined for this procedure to ultimately succeed. Case history We present the case of an eight-month-old girl with cryptogenic acute liver failure who underwent APOLT. She developed postoperative liver dysfunction, most likely owing to the persistence of the diseased native liver, ultimately leading to an orthotopic retransplantation. She remains well on follow-up review. Conclusions A tempered approach to selecting patients for APOLT (especially with regard to aetiology of acute liver failure) makes it a safe and effective alternative to orthotopic liver transplantation.

Published: November 2018

A evapotranspiração é um dos parâmetros de maior incerteza no gerenciamento de recursos hídricos e manejo da irrigação. Antes da escolha de determinado método para estimativa da evapotranspiração de referência (ETo) em uma região, é de extrema importância avaliar o grau de exatidão do modelo. A presente pesquisa objetivou avaliar o desempenho de 30 métodos para estimativa da ETo para Chapadão do Sul, MS. Os dados meteorológicos foram retirados do Instituto Nacional de Meteorologia no período de quatro anos (2008 a 2011). O método tomado como padrão foi o Penman-Monteith-FAO56; e a comparação dos resultados foi por meio do coeficiente de determinação (r2), dos coeficientes “a” e “b” das regressões lineares, erro-padrão da estimativa (EPE), índice de concordância de Willmott (d), coeficiente de correlação de Pearson (r) e do coeficiente de confiança (c). Os melhores métodos para estimativa da ETo foram: Penman-Original, Stephens-Stewart, Radiação-Temperatura, Turc, Hargreaves-Original, Penman-FAO24, Thornthwaite, Abtew, Blaney-Criddle-FAO24, McCloud, Radiação-FAO24, Garcia-Lopez,
Thornthwaite-Modificado, Radiação-Global, Hargreaves-Samani e Jensen-Haise. Quando se tem apenas dados de temperatura, recomenda-se utilizar o método de McCloud. O método de Hargreaves-Samani poderá ser utilizado depois de sua equação receber calibração para a região de estudo. Os métodos Makkink, Priestley-Taylor, Camargo, Linacre, Hamon, Ivanov, Kharrufa, Blaney-Morin, McGuiness-Bordne, Romanenko, Lungeon, Hicks-Hess, Radiação-Líquida e Tanner-Pelton não devem ser utilizados para a estimativa da ETo em Chapadão do Sul.
Origins of Wilson’s Warblers migrating through southwest Canada: Adding value to banding data by using stable isotopes and genetic markers

Published: November 2018

Abstract
Stopovers used by birds during migration concentrate individuals from broad geographic areas potentially providing important information on catchment areas of birds moving through these sites. We combined stable isotope (δ2H), genetic fingerprinting and band recovery data to delineate the molt origins of Wilson’s Warblers (Cardellina pusilla) migrating through a stopover site in southwestern Canada in the fall. We assessed changes in δ2Hf indicating latitudinal origins with ordinal date to show this species likely underwent leapfrog migration through this site. Using the combined approach to determine origins, Wilson’s Warblers migrating through southwestern Alberta in 2015 were mostly from the western boreal population (n = 155, 96%) with some individuals from the Pacific Northwest (n = 1, 0.6%), Rocky Mountain (n = 2, 1.2%) and eastern boreal (n = 3, 1.8%) populations. Our results suggest that individuals migrating through our study site come from a broad catchment area potentially from a large part of northwestern North America. Future studies should link population changes at banding stations with other information to determine associations with large-scale landscape-level drivers (e.g. climate, land use).
Danger of false negative (exclusion) or false positive (diagnosis) for ‘congenital thrombophilia’ in the age of anticoagulants
Authors: Favaloro Emmanuel J. 
Published: November 2018

Abstract

Background
Most guidelines and experts recommend against performance of thrombophilia testing in general, and specifically against testing patients on pharmacological anticoagulants, due to substantially increased risk of false positive identification. For example, vitamin K antagonist (VKA) therapy affects protein C (PC) and protein S (PS), as well as some clotting assays (e.g. as used to investigate activated PC resistance [APCR]). Although heparin may also affect clotting assays, most commercial methods contain neutralisers to make them ‘insensitive’ to therapeutic levels. Direct oral anticoagulants (DOACs) also affect a wide variety of thrombophilia assays, although most reported data has employed artificial in vitro spiked samples.

Methods
In the current report, data from our facility for the past 2.5 years has been assessed for all ‘congenital thrombophilia’ related tests, as evaluated against patient anticoagulant status. We processed 10,571 ‘thrombophilia’ related test requests, including antithrombin (AT; n=3470), PC (n=3569), PS (n=3585), APCR (n=2359), factor V Leiden (FVL; n=2659), and prothrombin gene mutation (PGM; n=2103).

Results
As expected, VKA therapy affected PC and PS, and despite manufacturer claims, also APCR. Most assays, as suggested by manufacturers, were largely resistant to heparin therapy. DOACs’ use was associated with falsely low APCR ratios (i.e. FVL-like effect) and somewhat unexpectedly, anti-Xa agents apixaban and rivaroxaban were also associated with lower AT and higher PS values.

Conclusions
It is concluded that ex-vivo data appears to confirm the potential for both false positive and false negative ‘thrombophilia’ events in patients on anticoagulant (including DOAC) treatment.
Harriet Tubman and Andrew Jackson on the Twenty-Dollar Bill: A Monstrous Intimacy
Authors: Thompson Sheneese , Barchiesi Franco 
Published: November 2018

Abstract
The controversy surrounding the announcement by the US Treasury, in April 2016, that the portraits of Harriet Tubman and Andrew Jackson will “share” the twenty-dollar bill-which the latter has embodied for almost a century-highlights a glaring incongruity: A formerly enslaved black woman and abolitionist leader is being placed in iconic proximity with an exemplary historical representative of the United States as a national experiment built on whiteness, slavery, and genocide. Our essay revolves around three basic questions: Why Tubman? Why Jackson? Why Now? The Treasury’s decision and its subsequent vicissitudes allow insights into the blurring of Barack Obama’s avowed “post-racialism,” which presided over the idea to redesign the currency, into the overt white supremacy and anti-black violence at the onset of the Trump regime, which has de facto frozen the implementation of the new bill. The story serves, namely, as a commentary on paradigmatic antiblackness as a force that, being constitutive of American civil society, has been fortified by the “post-racial” pretences of the Obama era. With reference to Christina Sharpe’s notion of “monstrous intimacy” and Saidiya Hartman’s theorization of “fungibility,” we argue that the twenty-dollar bill affair reflects the ways in which the interlocutory life of civil society is fortified by the continuous positioning, in popular imagination and discourse, of the black female body as inert matter in modes of appropriation, violence, and representation that sustain America’s political and libidinal economy.
The Lean In Collection: Women, Work, and the Will to Represent
Authors: West Caroline 
Published: November 2018

Abstract
In February 2014, Getty Images, the largest international stock photography agency, and LeanIn. org, Facebook COO Sheryl Sandberg’s women’s empowerment foundation, announced a new partnership that aimed to change the way women are portrayed in stock photography. The “Lean In Collection” with Getty seeks to challenge visual gendered stereotypes ascribed to both sexes in the daily life of work, home, and family life in advertising imagery. While the overarching ambition of gender empowerment implicit in the mission of Lean In is a worthwhile goal, I look to the problematic relationship rooted in the partnership between Lean In’s gender empowerment initiative and the role of Getty Images in trafficking aesthetic stereotypes for profit. Using methods of visual analysis and feminist critique, I argue that the photographs idealise a concept of female empowerment that is steeped in the rationale of neoliberal economics, which narrowly circumscribes gender citizenship according to the mandates of market logic. The Lean In Collection describes gender equality not as a right of citizenship procured by the state, but as a depoliticised and individualised negotiation.
What we talk about when we talk about space and narrative (and why we’re not done talking about it)
Authors: Parker Joshua 
Published: November 2018

AbstractNarrative has often been considered “an art of time.” This essay traces some of the historical reasons for this state of the field, or fields, of narratology, pinpointing spots in classical, postclassical and contemporary narrative theory where compensation was attempted or is being made through a focus on space instead of time. It suggests that as geography and geographers have become increasingly interested in narrative approaches in dealing with concepts, visualization, and digitalization, it is perhaps (once again) time narratology itself, while continuing to focus on and explore space and place, took account of its history of treating them and looked at how geography has implemented narratological concepts in its technical and philosophical approaches.
Divergent theories, converging evidence: The constructional semantics of competing future constructions
Authors: Hartmann Stefan 
Published: November 2018

Abstract
This paper investigates the alternation between two competing German future constructions, the werden + Infinitive construction and the futurate present, from a usage-based perspective. Two lines of evidence are combined: On the one hand, a pilot corpus study indicates that werden + Infinitive is more likely to be used for referring to distant-future events than to near-future events. However, syntactic factors seem to be at least as decisive as semantic ones for speakers’ choice between the two constructions. On the other hand, an experimental study taps into language users’ interpretation of sentences framed in one of the two constructions. It can be shown that the grammatical framing does not significantly affect participants’ estimates of the temporal distance of the events to which the stimuli sentences refer. This suggests that the meaning differences between the two constructions be more nuanced, e.g. pertaining to discourse-pragmatic functions.
Idempotents, group membership and their applications
Authors: Porubský Štefan 
Published: November 2018

AbstractŠ. Schwarz in his paper [SCHWARZ, Š.:Zur Theorie der Halbgruppen, Sborník prác Prírodovedeckej fakulty Slovenskej univerzity v Bratislave, Vol. VI, Bratislava, 1943, 64 pp.] proved the existence of maximal subgroups in periodic semigroups and a decade later he brought into play the maximal subsemigroups and thus he embodied the idempotents in the structural description of semigroups [SCHWARZ, Š.:Contribution to the theory of torsion semigroups, Czechoslovak Math. J.3(1) (1953), 7–21]. Later in his papers he showed that a proper description of these structural elements can be used to (re)prove many useful and important results in algebra and number theory. The present paper gives a survey of selected results scattered throughout the literature where an semigroup approach based on tools like idempotent, maximal subgroup or maximal subsemigroup either led to a new insight into the substance of the known results or helped to discover new approach to solve problems. Special attention will be given to some disregarded historical connections between semigroup and ring theory.
Weak pseudo-BCK algebras
Authors: Ciungu Lavinia Corina 
Published: November 2018

Abstract
In this paper we define and study the weak pseudo-BCK algebras as generalizations of weak BCK-algebras, extending some results given by Cı⃖rulis for weak BCK-algebras. We give some characterizations of weak pseudo-BCK algebras and we prove that a weak pseudo-BCK algebra satisfying the right distribution laws is a BCK-algebra. We define the class of commutative weak pseudo-BCK algebras, and we give equivalent definitions and characterization theorems for commutative weak pseudo-BCK algebras. The classes of quasi pseudo-BCK algebras and weak pseudo-BCK(E) algebras are introduced and a characterization theorem for quasi pseudo-BCK algebras is given. We prove that any weak pseudo-BCK(E) algebra is a pseudo-BE algebra and the class of commutative weak pseudo-BCK(E) algebras is equivalent to the class of commutative pseudo-BCK algebras.

Local-periodic solutions for functional dynamic equations with infinite delay on changing-periodic time scales
Authors: Wang Chao , Agarwal Ravi P. , O’Regan Donal 
Published: November 2018

Abstract
In this paper, by using the concept of changing-periodic time scales and composition theorem of time scales introduced in 2015, we establish a local phase space for functional dynamic equations with infinite delay (FDEID) on an arbitrary time scale with a bounded graininess function μ. Through Krasnoseľskiĭ’s fixed point theorem, some sufficient conditions for the existence of local-periodic solutions for FDEID are established for the first time. This research indicates that one can extract a local-periodic solution for dynamic equations on an arbitrary time scale with a bounded graininess function μ through some index function.
Anglo-Saxon Studies in Heidelberg: Georg Jellinek, Max Weber and Ernst Troeltsch
Authors: Graf Friedrich Wilhelm 
Published: November 2018

AbstractIn the German Kaiserreich the University of Heidelberg was known as a liberal academic institution, with internationally well-known professors and many students from foreign countries. Young and innovative scholars in the institution included the Protestant theologian and philosopher Ernst Troeltsch (1865-1923), the sociologist Max Weber (1869-1920) and the Professor of Public Law Georg Jellinek (1851-1911) who studied the origins and driving forces of capitalism and of modern occidental rationalism. These scholars were interested in the ‛cultural significance’ of religious beliefs and their ethical implications. They saw religion as a relatively autonomous cultural force sui generis. In close intellectual interaction they focused on the religious roots of modern human rights and the strong ethical differences between Lutheranism and Calvinism.
Migration, Gesundheit und soziale Lage

Published: November 2018

ZusammenfassungDas Zusammenspiel zwischen Migration, Gesundheit und sozialer Lage ist durch verschiedene Wirkmechanismen gekennzeichnet. Die soziale Lage beeinflusst gesundheitliche Chancen und Risiken sowie die Migration selbst und trägt dazu bei, ob migrationsbedingte Einflüsse auf die Gesundheit verstärkt oder abgeschwächt werden. Migration ist bedeutend für die Erklärung gesundheitlicher Ungleichheit, obgleich Verzerrungen und Messartefakte bei Interpretationen berücksichtigt werden müssen.
