Efficacy of Cardiac Blood Pool Activity in Hepatobiliary Scintigraphy for Diagnosis of Neonatal Hepatitis in Patients with Suspected Biliary Atresia
Authors: Khan Noorjahan , Begum Shamim MF , Mutsuddy Pupree , Sultana Sadia 
Published: August 2018

<p><strong><em>Background</em></strong><strong>:</strong> Biliary atresia (BA) is the commonest fatal liver disorder in children. It results from developmental anomaly due to fibrosis of extra hepatic bile ducts. The reported global incidence of biliary atresia varies from 5/100,000 to 32/100,000 live births. Accurate diagnosis is important before 8 weeks of age, since hepatoportoenterostomy (Kasai’s procedure) has a 90% success rate at this stage whereas success rate drops to 20% beyond 3 months. On the other hand, neonatal hepatitis (NH) which is other most common cause of neonatal cholestasis (NC) needs conservative treatment. So, differentiation of biliary atresia from neonatal hepatitis is very crucial. Hepatobiliary scintigraphy (HBSG) is most popular method to differentiate biliary atresia from neonatal hepatitis. But in severe neonatal hepatitis the diagnosis become inconclusive when excretion of radiotracer in bowel become absent along with prolonged cardiac activity. Prolonged cardiac blood pool activity in hepatobiliary scintigraphy is an indication of hepatocyte destruction in neonatal hepatitis. The aim of the study was to assess the efficacy of cardiac blood pool in hepatobiliary scintigraphy for diagnosis of neonatal hepatitis in suspected biliary atresia patient.</p><p><strong><em>Patients and methods:</em></strong> A total of 24 infants with history of conjugated hyperbilirubinaemia underwent HBSG showed prompt cardiac blood pool activity (9 infants) and also with prolonged cardiac blood pool (15 infants) with no excretion of radiotracer in bowel either in early or delayed images was included in the study. The findings of HBSG were compared with percutaneous liver biopsy findings and analyzed.</p><p><strong><em>Result:</em></strong><strong> </strong>Among 24 infants prolonged cardiac blood pool activity in HBSG was observed in 11 (73.3%) BA infants and 4 (44.4%) of NH infants. Absent bowel activity with prompt clearance of cardiac blood pool activity was observed in 4 (26.7%) BA infants and 5 (55.6%) NH infants. The difference was not statistically significant (<em>p</em>&gt;0.05).The calculated sensitivity of cardiac blood pool activity in HBSG for evaluation of NH was 44.4%, specificity was 26.7%, accuracy was 33.3%, positive predictive value (PPV) was 26.7% and negative predictive value (NPV) was 44.4%. The sensitivity, specificity, PPV, NPV and accuracy were low due to large number of false positive infants which might be due to complete obstruction of bile duct or due to early hepatocyte destruction (within 3 months of age).</p><p><strong><em>Conclusion:</em></strong><strong> </strong>Although prolonged cardiac blood pool activity was considered as diagnostic criteria for the diagnosis of NH in suspected BA patient but it could not be able to differentiate these two conditions.</p><p>Bangladesh J.

Crystal Structure of the Labile Complex of IL-24 with the Extracellular Domains of IL-22R1 and IL-20R2

Abstract
Crystal structure of the ternary complex of human IL-24 with two receptors, IL-22R1 and IL-20R2, has been determined at 2.15 Å resolution. A crystallizable complex was created by a novel approach involving fusing the ligand with a flexible linker to the presumed low-affinity receptor, and coexpression of this construct in Drosophila S2 cells together with the presumed high-affinity receptor. This approach, which may be generally applicable to other multiprotein complexes with low-affinity components, was necessitated by the instability of IL-24 expressed by itself in either bacteria or insect cells. Although IL-24 expressed in Escherichia coli was unstable and precipitated almost immediately upon its refolding and purification, a small fraction of IL-24 remaining in the folded state was shown to be active in a cell-based assay. In the crystal structure presented here, we found that two cysteine residues in IL-24 do not form a predicted disulfide bond. Lack of structural restraint by disulfides, present in other related cytokines, is most likely reason for the low stability of IL-24. Although the contact area between IL-24 and IL-22R1 is larger than between the cytokine and IL-20R2, calculations show the latter interaction to be slightly more stable, suggesting that the shared receptor (IL-20R2) might be the higher-affinity receptor.
Sensitization in Aluminum Alloys: Effect on Acoustic Parameters
Authors: Chukwunonye C.U. , Jones Nicholas J. , Petculescu Gabriela 
Published: August 2018

Velocity and attenuation of shear and longitudinal sound waves were measured as a function of sensitization level in AA5083-H116 and AA5456-H116 aluminum alloys using two different techniques: resonant ultrasound spectroscopy (RUS) and pulse echo (PE). The frequency range for RUS was 0.3 MHz to 1 MHz. For PE, longitudinal 3.5 MHz and shear 1 MHz transducers were used. Sensitization was artificially induced in the laboratory by isothermally heating specimens at temperatures of 120°C, 175°C, 185°C, and 240°C for fixed periods of time (12 h to 96 h, the longer times for the lower temperatures). Measurements were repeated after each heating sequence. The overall changes are reported as percent difference between the as received and the fully sensitized states. The quantity that was found to be most sensitive to the degree of sensitization in this study is the attenuation coefficient of longitudinal waves, αL. The measured change in αL exceeds 20%, with error bars within 1% to 4%. Despite the magnitude of the error bars, the αL vs. degree-of-sensitization curve is clear and smooth. The shear wave velocity changed by 1.2% to 1.5%, with error bars within 0.01% to 0.1%. The larger change was observed for the AA5456 alloy, which contains more Mg. The longitudinal wave velocity was found to change by 0.5% for the 5456 alloy, with error bars within 0.004% to 0.02%. The attenuation coefficient for shear waves was not measured. This study identifies multiple ultrasonic parameters that can be combined into a new, on-site, nondestructive tool for quantitatively monitoring the sensitization level in Mg-rich aluminum alloys, with possible extensions to other materials.
Characterization of aerosol composition, aerosol acidity, and organic acid partitioning at an agriculturally intensive rural southeastern US site

Abstract. The implementation of stringent emission regulations has resulted in the
decline of anthropogenic pollutants including sulfur dioxide (SO2),
nitrogen oxides (NOx), and carbon monoxide (CO). In contrast, ammonia
(NH3) emissions are largely unregulated, with emissions projected to
increase in the future. We present real-time aerosol and gas measurements
from a field study conducted in an agriculturally intensive region in the
southeastern US during the fall of 2016 to investigate how NH3 affects
particle acidity and secondary organic aerosol (SOA) formation via the
gas–particle partitioning of semi-volatile organic acids. Particle water and
pH were determined using the ISORROPIA II thermodynamic model and validated
by comparing predicted inorganic HNO3-NO3- and
NH3-NH4+ gas–particle partitioning ratios with measured values.
Our results showed that despite the high NH3 concentrations (average 8.1±5.2 ppb), PM1 was highly acidic with pH values ranging from 0.9
to 3.8, and an average pH of 2.2±0.6. PM1 pH varied by
approximately 1.4 units diurnally. Formic and acetic acids were the most
abundant gas-phase organic acids, and oxalate was the most abundant
particle-phase water-soluble organic acid anion. Measured particle-phase
water-soluble organic acids were on average 6 % of the total
non-refractory PM1 organic aerosol mass. The measured molar fraction of
oxalic acid in the particle phase (i.e., particle-phase oxalic acid molar
concentration divided by the total oxalic acid molar concentration) ranged
between 47 % and 90 % for a PM1 pH of 1.2 to 3.4. The measured oxalic acid
gas–particle partitioning ratios were in good agreement with their
corresponding thermodynamic predictions, calculated based on oxalic acid's
physicochemical properties, ambient temperature, particle water, and pH. In
contrast, gas–particle partitioning ratios of formic and acetic acids were not well
predicted for reasons currently unknown. For this study, higher NH3
concentrations relative to what has been measured in the region in previous
studies had minor effects on PM1 organic acids and their influence on
the overall organic aerosol and PM1 mass concentrations.
Drought and vegetation change in the central Rocky Mountains and western Great Plains: potential climatic mechanisms associated with megadrought conditions at 4200 cal yr BP
Authors: Carter Vachel A. , Shinker Jacqueline J. , Preece Jonathon 
Published: August 2018

Abstract. Droughts are a naturally re-occurring phenomena that result in economic and
societal losses. Yet, the most historic droughts that occurred in the 1930s
and 1950s in the Great Plains and western United States were both shorter in
duration and less severe than megadroughts that have plagued the region in
the past. Roughly 4200 years ago, a ∼150-year long megadrought occurred
in the central Rocky Mountains, as indicated by sedimentary pollen evidence
documenting a brief and unique change in vegetation composition
from Long Lake, southeastern Wyoming. Neighbouring the central Rocky Mountains, several
dune fields reactivated in the western Great Plains around this time period
illustrating a severe regional drought. While sedimentary pollen provides
evidence of past drought, paleoecological evidence does not provide context
for the climate mechanisms that may have caused the drought. Thus, a modern
climate analogue technique was applied to the sedimentary pollen and regional
dune reactivation evidence identified from the region to provide a conceptual
framework for exploring possible mechanisms responsible for the observed
ecological changes. The modern climate analogues of 2002/2012 illustrate that
warm and dry conditions persisted through the growing season and were
associated with anomalously higher-than-normal geopotential heights centred
over the Great Plains. In the spring, higher-than-normal heights suppressed
moisture transport via the low-level jet from the Gulf of Mexico creating a
more southwesterly component of flow. In the summer, higher-than-normal
heights persisted over the northern Great Plains resulting in a wind shift
with an easterly component of flow, drawing in dry continental air into the
study region. In both cases, lower-than-normal moisture in the atmosphere
(via 850 mbar specific humidity) inhibited uplift and potential
precipitation. Thus, if the present scenario existed during the 4.2 ka
drought, the associated climatic responses are consistent with local and
regional proxy data suggesting regional drought conditions in the central
Rocky Mountains and western Great
Plains.
Twenty-five years of cloud base height measurements by ceilometer in Ny-Ålesund, Svalbard
Authors: Maturilli Marion , Ebell Kerstin 
Published: August 2018

Abstract. Clouds are a key factor for the Arctic amplification of global warming, but
their actual appearance and distribution are still afflicted by large
uncertainty. On the Arctic-wide scale, large discrepancies are found between
the various reanalyses and satellite products, respectively. Although
ground-based observations by remote sensing are limited to point
measurements, they have the advantage of obtaining extended time series of
vertically resolved cloud properties. Here, we present a 25-year data record
of cloud base height measured by ceilometer at the Ny-Ålesund, Svalbard,
Arctic site. We explain the composition of the three sub-periods with
different instrumentation contributing to the data set, and show examples of
potential application areas. Linked to cyclonic activity, the cloud base
height provides essential information for the interpretation of the surface
radiation balance and contributes to the understanding of meteorological
processes. Furthermore, it is a useful auxiliary component for the analysis
of advanced technologies that provide insight into cloud microphysical
properties, like the cloud radar. The long-term time series also allows
derivation of an annual cycle of the cloud occurrence frequency, revealing
the more frequent cloud cover in summer and the lowest cloud cover amount in
April. However, as the use of different ceilometer instruments over the years
potentially imposed inhomogeneities onto the data record, any long-term trend
analysis should be avoided. The Ny-Ålesund cloud base height data from August 1992 to July 2017 are
provided in a high temporal resolution of 5 min (1 min) before (after)
July 1998, respectively, at the PANGAEA repository
(https://doi.org/10.1594/PANGAEA.880300).
Basal friction of Fleming Glacier, Antarctica – Part 2: Evolution from 2008 to 2015
Authors: Zhao Chen , Gladstone Rupert M. , Warner Roland C. , King Matt A. , Zwinger Thomas , Morlighem Mathieu 
Published: August 2018

Abstract. The Wordie Ice Shelf–Fleming Glacier system in the southern Antarctic
Peninsula has experienced a long-term retreat and disintegration of its ice
shelf in the past 50 years. Increases in the glacier velocity and dynamic
thinning have been observed over the past two decades, especially after 2008
when only a small ice shelf remained at the Fleming Glacier front. It is
important to know whether the substantial further speed-up and greater
surface draw-down of the glacier since 2008 is a direct response to ocean
forcing, or driven by feedbacks within the grounded marine-based glacier
system, or both. Recent observational studies have suggested the
2008–2015 velocity change was due to the ungrounding of the Fleming Glacier
front. To explore the mechanisms underlying the recent changes, we use a
full-Stokes ice sheet model to simulate the basal shear stress distribution
of the Fleming system in 2008 and 2015. This study is part of the first high
resolution modelling campaign of this system. Comparison of inversions for
basal shear stresses for 2008 and 2015 suggests the migration of the
grounding line ∼9 km upstream by 2015 from the 2008 ice front/grounding
line positions, which virtually coincided with the 1996 grounding line
position. This migration is consistent with the change in floating area
deduced from the calculated height above buoyancy in 2015. The retrograde
submarine bed underneath the lowest part of the Fleming Glacier may have
promoted retreat of the grounding line. Grounding line retreat may also be
enhanced by a feedback mechanism upstream of the grounding line by which
increased basal lubrication due to increasing frictional heating enhances
sliding and thinning. Improved knowledge of bed topography near the grounding
line and further transient simulations with oceanic forcing are required to
accurately predict the future movement of the Fleming Glacier system
grounding line and better understand its ice dynamics and future contribution
to sea level.
El villancico sevillano del siglo XVII (1621–1700)The Sevillian Villancico During the Seventeenth Century (1621–1700)
Authors: Lorenzo Cipriano López 
Published: August 2018

Abstract
From the analysis of 316 copies of Sevillian villancicos from the seventeenth century (1621–1700) we can witness a successful and consolidated publishing genre. Its strong and repeated identity features will help us to describe the context of creation and the printed diffusion. Thereby, the public cover they adopted is the formulation and the plastic result of a procedure of that period that still needs to be studied. We will analyze the places and the festivities celebrated, the main poets and some formal aspects of particular interest. Essentially, the goal of this paper is to introduce a poetic product, key in the birth of an esthetic for the Low Baroque.
Entre pliegos anda el juego: Juan Rufo y las cortes literarias en el tiempo de La AustríadaTrading Letters: Juan Rufo and the Literary Courts In The Days of La Austríada
Authors: Marín Cepeda Patricia 
Published: August 2018

Abstract
Juan Rufo (Córdoba, 1547 – ca. 1620), a writer and soldier of humble origins, shaped his image as a poet with the publication of his epic poem La Austríada (1584) and the social relations that he developed with court nobility during that period. Two poet's autograph letters sent to the future Cardinal Ascanio Colonna (1560–1608) speak vividly about these relations of the writer with several members of the nobility, as well as the relationship of his epic poem with the literary and court context of its time. In this article, I analyze Rufo's self-fashioning strategies in the period when he published La Austríada, study some of his Spanish-Italian relations with court nobility, and publish, for the first time, the complete text of his letters to Colonna.
Francisco de Castilla, Boethius and the Search for True Happiness
Authors: Javier Huamán Ricardo 
Published: August 2018

Abstract
Francisco de Castilla published his treatise on the virtues, Teórica de virtudes, in 1518. The influence of Boethius' most famous work, De consolatione philosophiae, on medieval literature and imagery is well known. The connection of the four poems in Teórica to Boethius has not been studied. This lack of attention may be due solely to an ignorance of Castilla's poetic output. Castilla's case is noteworthy because he mentions Boethius by name several times, recreates De consolatione philosophiae in “Diálogo entre la Miseria humana y el Consuelo” and includes Lady Philosophy as a character in “Inquisición de la felicidad.” This work investigates the relationship between De consolatione and Teórica and how Castilla learns to express the finding of true happiness in Boethian terms.
El epíteto en laGrandeza Mexicanade Bernardo de BalbuenaThe Epithet in theGrandeza Mexicanaby Bernardo de Balbuena
Authors: Ávalos Etna 
Published: August 2018

AbstractWithin the framework of Spanish American mannerism, this article explores the function and variety of epithets found in Bernardo de Balbuena's Grandeza Mexicana (1604). This work examines the classical epithets in the poem based on their role in the construction of a hyperbolic image of Mexico City and its representation as a central figure of the world. This study also focuses on the role of the epithets in the articulation of metaphors and concettos that cause the argument to unfold into multiple meanings. This analysis shows how the epithets serve as “decoders” of various hidden concepts (conceits) that reveal the complexity of a multidimensional message, both political and artistic.
