Published: June 2019

This study aims to formulate woodapple flavor effervescent tablets in the lab experiment. Four factors with three levels each were investigated including: acid citric (14%, 16%, 18%), natri-bicarbonate (10%, 14%, 18%), saccharose (45%, 50%, 55%), and PEG 6000 (4%, 5%, 6%). Nine profiles were constructed following a fractional factorial design – the Graeco Latin square. Each profile was then measured based on four characteristics/criteria: (1) - flow properties of wood apple powder (before compression process), (2) - weight variation and (3) - disintegration time (after compression process); and (4) wood-apple effervescent tablets which were rated for overall liking by 105 consumers. The results showed that 8 over 9 profiles have a good flow property, meaning that it is capable of compressing tablets. The weight variation among tablets is less than 5%. In addition to that, the disintegration time of an effervescent tablet, about 1 gram into 200 mL water, is less than 300 seconds (5 minutes). Based on the preliminary evaluation of our internal sensory panel, six over eight profiles were chosen for  taking the tests to the consumers’ liking based on IPM method. The results showed that profile 2 (A.Citric 14%,  NaHCO3 14%, saccharose 50% , PEG 6000 5%,wood apple flavor 16% and vit.C 1%) and profile 5 (A.Citric 16%, NaHCO3 14%, saccharose 50%, PEG 6000 4%, wood apple flavor 15% and vit.C 1%) obtain  maximum liking score rated by the consumers. We expect that the results of this study will benefit R&D staff in food and pharmaceutical companies who want to diversify their local products.

it is some kind of a benchmark that allows making
correct judgment concerning changes in the temporomandibular joint occurring through various diseases
and prosthetic events that entail new ratios not only in
the dentition area, yet also in the temporomandibular

Published: June 2019

The temporal operculum is a region of the
temporal lobe upper surface, which is bounded at the front
by transverse temporal gyri, and from behind – by the end of
the lateral cerebral sulcus.
Aim of study: to identify the shape and the dimensional
features of the temporal operculum in people aged 1–21.
Fixed brain preparations (n = 47) were used to measure
the depth of the lateral sulcus at the level of the temporal
operculum, and the temporal operculum length along its
outer edge; the temporal operculum area was calculated as
well. The studied material was divided into groups following
age periodization: early childhood (n = 8); the first period
of childhood (n = 18); the second period of childhood (n
= 7); adolescence (n = 5), youthhood (n = 9). The study
produced average values for the lateral sulcus depth, the
temporal operculum length and area in people aged 1–21.
The triangular shape of the temporal operculum has been
found to be the most common. The temporal operculum
area in early childhood and the first period of childhood, as
well as the temporal operculum length in early childhood
prevail in the left hemisphere (p <0.05). Viewed from
the age aspect, the depth of the lateral sulcus varies less
significantly than the length and the area of the temporal
operculum. The temporal operculum area correlated more
with the operculum length rather than with the depth of the
lateral sulcus
Infektionskontrolle mittels GC-IMS und Einsatz von Wundpuder (Klinoptilolith) bei chronischen infizierten Wunden
Authors: Becher Gunther , Al Shihabie Ibaa , Schulz Jörg
Published: June 2019

In a clinical setting a standardized regime
was used on 33 patients with chronic or acute wounds to
detect and treat a wound infection. A GC-IMS was used
as a new method for Infection Diagnostics. Wound size,
germ colonization and clinical staging were documented on
three examination dates in a distance from one week. For
treatment of the wounds a novel wound powder Toxaprevent
skin® ("Klinoptilolith") was used.
Systematic trends were noticeable compared to the initial
findings, so that an antimicrobial effect of the treatment can
be assumed.
Due to the variability of germ infestation and the small
number of patients assigned, a statistically significant
statement is not to be made.
The results of microbiological studies using a classic wound
smear and the MCC-IMS technique show that the latter
has a distinct advantage over traditional microbiology.
This methodology allows for immediate germ assignment
and can be repeated as often as necessary. An advantage
of germ identification using IMS may be that the method
only responds to clinically relevant germ growth, while
traditional studies from the smear can also be positive
for randomly present ambient germs. The possibility of
immediate germ assignment makes promptly specific
therapy possible.
A prerequisite for a clinical application would be validation
on large groups in order to define the germ-specific
fingerprints even in the case of mixed infections.
Based on the study results so far, it can be concluded that the
Toxaprevent Skin powder® has a positive therapeutic effect
on wound healing, has good local tolerability and has a low
side effect profile.
In order to find out further therapeutic effects principles
of the Toxaprevent skin Powder®, further clinical
application studies under outpatient conditions would be
recommended, with the need to review local and systemic
examination parameters (e.g. local Wound assessment, germ
spectrum, systemic inflammatory parameters, immunology,
oxygen partial pressure, proteins, muscle enzymes).
Host–guest interactions between p-sulfonatocalix[4]arene and p-sulfonatothiacalix[4]arene and group IA, IIA and f-block metal cations: a DFT/SMD study
Authors: Nikolova Valya K , Kirkova Cristina V , Angelova Silvia E , Dudev Todor M
Published: June 2019

The molecular recognition in aqueous solution is extremely important because most biological processes occur in aqueous solution. Water-soluble members of the calix[n]arene family (e.g., p-sulfonato substituted) can serve as model systems for studying the nature and manner of interactions between biological receptors and small ions. The complex formation behavior of water-soluble p-sulfonatocalix[4]arene and thiacalix[4]arene and group IA, IIA and f-block metal cations has been investigated computationally by means of density functional theory computations in the gas phase and in aqueous environment. The calculated Gibbs free energy values of the complex formation reaction of these ligands with the bare metal cations suggest a spontaneous and energy-favorable process for all metal cations in the gas phase and only for Na+, Mg2+, Lu3+ cations in water environment. For one of the studied cations (La3+) a supramolecular approach with explicit solvent treatment has been applied in the study of the effect of metal hydration on the complexation process. The La3+ binding to the p-sulfonatocalix[4]arene host molecule (now in the metal’s second coordination shell) is still exergonic as evidenced by the negative Gibbs free energy values (ΔG1 and ΔG78). The combination of implicit/explicit solvent treatment seems useful in the modeling of the p-sulfonatocalix[4]arene (and thiacalix[4]arene) complexes with metal cations and in the prediction of the thermodynamic parameters of the complex formation reactions.

Published: June 2019

Digital retail (online retail or e-commerce) sector is continuously expanding its stake in the global economy each year. According to the statistics, online retail share of the total global retail sales takes approximately 11.9% in 2018 and is expected to reach 17.5% at the end of 2021. The same pattern of rapid growth was noticed more than 18 years ago when a burst of dot-com bubble crashed many of the internet-based online shopping companies. “Growth over profits” mentality and overestimated perception of the magnitude of online sales resulted in a superficial understanding of the business’ financial performance. Because of that, it is highly necessary to analyze and adequately evaluate the financial performance of digital retail companies. Thus, the purpose of this article is to investigate the top 4 digital retail companies’ financial performance by applying multiple criteria decision analysis (MCDA) TOPSIS and SAW methods to demonstrate that sales turnover is not the only and the prime measure to evaluate the successful company’s financial performance.
The Case of H2C3O Isomers, Revisited: Solving the Mystery of the Missing Propadienone
Authors: Shingledecker Christopher N. , Álvarez-Barcia Sonia , Korn Viktoria H. , Kästner Johannes
Published: June 2019

To date, two isomers of H2C3O have been detected, namely, propynal (HCCCHO) and cylclopropenone (c-H2C3O). A third, propadienone (CH2CCO), has thus far eluded observers despite the fact that it is the lowest in energy of the three. This previously noted result is in contradiction to the minimum energy principle, which posits that the abundances of isomers in interstellar environments can be predicted based on their relative stabilities and suggests, rather, the importance of kinetic over thermodynamic effects in explaining the role of such species. Here, we report results of ab initio quantum chemical calculations of the reaction between H and (a) HC3O, (b) H2C3O (both propynal and propadienone), and (c) CH2CHCO. We have found that, among all possible reactions between atomic hydrogen and either propadienone or propynal, only the destruction of propadienone is barrierless and exothermic. That this destruction pathway is indeed behind the nondetection of CH2CCO is further suggested by our finding that the product of this process, the radical CH2CHCO, can subsequently react barrierlessly with H to form propenal (CH2CHCHO) which has, in fact, been detected in regions where the other two H2C3O isomers are observed. Thus, these results not only shed light on a previously unresolved astrochemical mystery, but also further highlight the importance of kinetics in understanding the abundances of interstellar molecules.
Revisiting the Temperature of the Diffuse ISM with CHESS Sounding Rocket Observations

Published: June 2019

Measuring the temperature and abundance patterns of clouds in the interstellar medium (ISM) provides an observational basis for models of the physical conditions within the clouds, which play an important role in studies of star and planet formation. The Colorado High-resolution Echelle Stellar Spectrograph is a far-ultraviolet rocket-borne instrument designed to study the atomic-to-molecular transitions within diffuse molecular and translucent cloud regions. The final two flights of the instrument observed

Scorpii (β Sco) and γ Arae. We present flight results of interstellar molecular hydrogen excitation on the sightlines, including measurements of the column densities and temperatures. These results are compared to previous values that were measured using the damping wings of low J″ H

absorption features. For β Sco, we find that the derived column density of the J″ = 1 rotational level differs by a factor of 2–3 when compared to the previous observations. We discuss the discrepancies between the two measurements and show that the source of the difference is due to the opacity of higher rotational levels contributing to the J″ = 1 absorption wing, increasing the inferred column density in the previous work. We extend this analysis to 9 Copernicus and 13 Far-Ultraviolet Spectroscopic Explorer spectra to explore the interdependence of the column densities of different rotational levels and how the H

kinetic temperature is influenced by these relationships. We find a revised average gas kinetic temperature of the diffuse molecular ISM of T
01 = 68 ± 13 K, 12% lower than the value found previously.

Published: June 2019

We present absorption variability results for 134 bona fide Mg ii broad absorption-line (BAL) quasars at 0.46 ≲ z ≲ 2.3 covering days to ∼10 yr in the rest frame. We use multiple-epoch spectra from the Sloan Digital Sky Survey, which has delivered the largest such BAL variability sample ever studied. Mg ii-BAL identifications and related measurements are compiled and presented in a catalog. We find a remarkable time-dependent asymmetry in the equivalent width (EW) variation from the sample, such that weakening troughs outnumber strengthening troughs, the first report of such a phenomenon in BAL variability. Our investigations of the sample further reveal that (i) the frequency of BAL variability is significantly lower (typically by a factor of 2) than that in high-ionization BALQSO samples, (ii) Mg ii-BAL absorbers tend to have relatively high optical depths and small covering factors along our line of sight, (iii) there is no significant EW-variability correlation between Mg ii troughs at different velocities in the same quasar, and (iv) the EW-variability correlation between Mg ii and Al iii BALs is significantly stronger than that between Mg ii and C iv BALs at the same velocities. These observational results can be explained by a combined transverse-motion/ionization-change scenario, where transverse motions likely dominate the strengthening BALs while ionization changes and/or other mechanisms dominate the weakening BALs.
Constraints on Dark Matter Microphysics from the Milky Way Satellite Population

Published: June 2019

Alternatives to the cold, collisionless dark matter (DM) paradigm in which DM behaves as a collisional fluid generically suppress small-scale structure. Herein we use the observed population of Milky Way (MW) satellite galaxies to constrain the collisional nature of DM, focusing on DM–baryon scattering. We first derive conservative analytic upper limits on the velocity-independent DM–baryon scattering cross section by translating the upper bound on the lowest mass of halos inferred to host satellites into a characteristic cutoff scale in the linear matter power spectrum. We then confirm and improve these results through a detailed probabilistic inference of the MW satellite population that marginalizes over relevant astrophysical uncertainties. This yields 95% confidence upper limits on the DM–baryon scattering cross section of 6 × 10−30 cm2 (10−27 cm2) for DM particle masses m

χ
of 10 keV (10 GeV); these limits scale as m

This analysis improves upon cosmological bounds derived from cosmic-microwave-background anisotropy measurements by more than three orders of magnitude over a wide range of DM masses, excluding regions of parameter space previously unexplored by other methods, including direct-detection experiments. Our work reveals a mapping between DM–baryon scattering and other alternative DM models, and we discuss the implications of our results for warm and fuzzy DM scenarios.

This Letter reports the discovery of spatially extended line-emitting nebula, reaching to ≈100 physical kpc (pkpc) from a damped

absorber (DLA) at z
DLA = 0.313 along the sightline toward quasi-stellar object (QSO) PKS 1127−145 (z
QSO = 1.188). This DLA was known to be associated with a galaxy group of dynamical mass M
group ∼ 3 × 1012
M
⊙, but its physical origin remained ambiguous. New wide-field integral field observations revealed a giant nebula detected in [O ii], Hβ, [O iii], Hα, and [N ii] emission, with the line-emitting gas following closely the motions of group galaxies. One of the denser streams passes directly in front of the QSO with kinematics that are consistent with the absorption profiles recorded in the QSO echelle spectra. The emission morphology, kinematics, and line ratios of the nebula suggest that shocks and turbulent mixing layers, produced as a result of stripped gaseous streams moving at supersonic speed across the ambient hot medium, contribute significantly to the ionization of the gas. While the DLA may not be associated with any specific detected member of the group, both the kinematic and dust properties are consistent with the DLA originating in streams of gas stripped from sub-L
* group members at ≲25 pkpc from the QSO sightline. This study demonstrates that gas stripping in low-mass galaxy groups is effective in releasing metal-enriched gas from star-forming regions, producing absorption systems in QSO spectra, and that combining absorption and emission-line observations provides an exciting new opportunity for studying gas and galaxy co-evolution.
Rising from Ashes or Dying Flash? The Mega Outburst of Small Comet 289P/Blanpain in 2013∗
Authors: Ye 叶 Quanzhi 泉志 , Clark David L.
Published: June 2019

Jupiter-family comet 289P/Blanpain was first discovered in 1819 and was then lost for ∼200 years, only to be rediscovered in 2003 as a small, weakly active comet. The comet is associated with the Phoenicids, an otherwise minor meteor shower that produced significant outbursts in 1956 and 2014. The shower points to the existence of significant mass-loss events of P/Blanpain in recent history. P/Blanpain was recovered during an apparent large outburst in 2013 July at an appreciable heliocentric distance of 3.9 au, with brightness increase of 9 mag, making it one of the largest comet outbursts ever observed. Here we present an analysis of archival data taken by several telescopes. We find that the 2013 outburst has produced ∼108 kg of dust, which accounts for a modest fraction (∼1%) of the mass of P/Blanpain’s nucleus as measured in 2004. Based on analysis of long-term light curve and modeling of coma morphology, we conclude that the 2013 outburst was most likely driven by the crystallization of amorphous water ice triggered by a spin-up disruption of the nucleus. A dust dynamical model shows that a small fraction of the dust ejecta will reach the Earth in 2036 and 2041, but are only expected to produce minor enhancements to the Phoenicid meteor shower. The 2013 outburst of P/Blanpain, though remarkable for a comet of small size, does not necessary imply a catastrophic disruption of the nucleus. The upcoming close encounter of P/Blanpain in 2020 January will provide an opportunity to examine the current state of the comet.
Phylogeography and species distribution modelling of Cryptocephalus barii (Coleoptera: Chrysomelidae): is this alpine endemic species close to extinction?
Authors: Brunetti Matteo , Magoga Giulia , Iannella Mattia , Biondi Maurizio , Montagna Matteo
Published: June 2019

The alternation of glacial and interglacial cycles of the Quaternary period contributed in shaping the current species distribution. Cold-adapted organisms experienced range expansion and contraction in response to the temperature decrease and increase, respectively. In this study, a fragment of the mitochondrial marker COI was used to investigate the phylogeography of Cryptocephalusbarii, a cold-adapted alpine leaf beetle species endemic of Orobie Alps, northern Italy. The relationships among populations, their divergence time, and the most probable migration model were estimated and are discussed in light of the Pleistocene climate oscillations. Through a species distribution modelling analysis, the current habitat suitability was assessed and the distribution in a future global warming scenario predicted. The main divergence events that led to the actual population structure took place from ~750,000 to ~150,000 years ago, almost following the pattern of the climate oscillations that led to the increase of the connections between the populations during cold periods and the isolation on massifs in warm periods. The most supported migration model suggests that the species survived to past adverse climatic conditions within refugia inside and at the limit of the actual range. The species distribution modelling analysis showed that C.barii is extremely sensitive to air temperature variations, thus the increase of temperature caused by global warming will reduce the suitable areas within the species range, leading to its possible extinction in the next 50 years. Cryptocephalusbarii is a representative case of how cold adapted and limited distributed species have been and could be affected by climate change, that highlights the implementation of conservation actions.

Genome-Wide Transcriptional Analysis Reveals Novel AhR Targets That Regulate Dendritic Cell Function during Influenza A Virus Infection
Authors: Franchini Anthony M , Myers Jason R , Jin Guang-Bi , Shepherd David M , Lawrence B Paige
Published: June 2019

Activation of the ligand inducible aryl hydrocarbon receptor (AhR) during primary influenza A virus infection diminishes host responses by negatively regulating the ability of dendritic cells (DC) to prime naive CD8+ T cells, which reduces the generation of CTL. However, AhR-regulated genes and signaling pathways in DCs are not fully known. In this study, we used unbiased gene expression profiling to identify differentially expressed genes and signaling pathways in DCs that are modulated by AhR activation in vivo. Using the prototype AhR agonist TCDD, we identified the lectin receptor Cd209a (DC-SIGN) and chemokine Ccl17 as novel AhR target genes. We further show the percentage of DCs expressing CD209a on their surface was significantly decreased by AhR activation during infection. Whereas influenza A virus infection increased CCL17 protein levels in the lung and lung-draining lymph nodes, this was significantly reduced following AhR activation. Targeted excision of AhR in the hematopoietic compartment confirmed AhR is required for downregulation of CCL17 and CD209a. Loss of AhR’s functional DNA-binding domain demonstrates that AhR activation alone is necessary but not sufficient to drive downregulation. AhR activation induced similar changes in gene expression in human monocyte-derived DCs. Analysis of the murine and human upstream regulatory regions of Cd209a and Ccl17 revealed a suite of potential transcription factor partners for AhR, which may coregulate these genes in vivo. This study highlights the breadth of AhR-regulated pathways within DCs, and that AhR likely interacts with other transcription factors to modulate DC functions during infection.

Published: June 2019

Signaling through CD27 plays a role in T cell activation and memory. However, it is currently unknown how this costimulatory receptor influences CD4+ effector T (Teff) cells in inflamed tissues. In the current study, we used a murine model of inducible self-antigen expression in the epidermis to elucidate the functional role of CD27 on autoreactive Teff cells. Expression of CD27 on Ag-specific Teff cells resulted in enhanced skin inflammation when compared with CD27-deficient Teff cells. CD27 signaling promoted the accumulation of IFN-γ and IL-2–producing T cells in skin draining lymph nodes in a cell-intrinsic fashion. Surprisingly, this costimulatory pathway had minimal effect on early T cell activation and proliferation. Instead, signaling through CD27 resulted in the progressive survival of Teff cells during the autoimmune response. Using BH3 profiling to assess mitochondrial cell priming, we found that CD27-deficient cells were equally as sensitive as CD27-sufficient cells to mitochondrial outer membrane polarization upon exposure to either BH3 activator or sensitizer peptides. In contrast, CD27-deficient Teff cells expressed higher levels of active caspase 8. Taken together, these results suggest that CD27 does not promote Teff cell survival by increasing expression of antiapoptotic BCL2 family members but instead acts by preferentially suppressing the cell-extrinsic apoptosis pathway, highlighting a previously unidentified role for CD27 in augmenting autoreactive Teff cell responses.

Image registration is the vital technology in computer vision. By developing precise image registration algorithm will meaningfully improve the techniques for the problems in computer vision. Registration process does geometrical alteration that aligns point present in one view of an object with similar points in another view of that object or another object .Steps involved in image registration are feature finding, matching of features, image transformation and resampling. Feature finding and matching have vital role in accuracy of the process. In this paper we have used SIFT (Scale Invariant Feature Transform) for the feature detection which is invariant to scaling, rotation and noise. KNN nearest neighbor is used for matching similar points and the other efficient method in reducing miss matches in the proposed algorithm is Random sample consensus method.

Abstract. Nitric oxide (NO) and nitrogen dioxide (NO2) are relevant to air
quality due to their roles in tropospheric ozone (O3) production. In
China, NOx emissions are very high and NOx emissions exhausted from on-road
vehicles make up 20 % of total NOx emissions. In order to detect the NO
and NO2 emissions on road, a dual-channel cavity ring-down spectroscopy
(CRDS) system for NO2 and NO detection has been developed. In the
system, NO is converted to NO2 by its reaction with excess O3
in the
NOx channel, such that NO can be determined through the difference
between two channels. The detection limits of NO2 and NOx for the
system are estimated to be about 0.030 (1σ, 1 s) and 0.040 ppb (1σ, 1 s), respectively. Considering the error sources of NO2
absorption cross section and RL determination, the total uncertainty of
NO2 measurements is about 5%. The performance of the system was
validated against a chemiluminescence (CL) analyser (42i, Thermo Scientific,
Inc.) by measuring the NO2 standard mixtures. The measurement results
of NO2 showed a linear correction factor (R2) of 0.99 in a slope
of 1.031±0.006, with an offset of (-0.940±0.323) ppb. An
intercomparison between the system and a cavity-enhanced absorption
spectroscopy (CEAS) instrument was also conducted separately for NO2
measurement in an ambient environment. Least-squares analysis showed that the
slope and intercept of the regression line are 1.042±0.002 and
(-0.393±0.040) ppb, respectively, with a linear correlation factor
of R2=0.99. Another intercomparison conducted between the system and
the CL analyser for NO detection also showed a good agreement within their
uncertainties, with an absolute shift of (0.352±0.013) ppb, a slope
of 0.957±0.007 and a correlation coefficient of R2=0.99. The
system was deployed on the measurements of on-road vehicle emission plumes
in Hefei, and the different emission characteristics were observed in the
different areas of the city. The successful deployment of the system has
demonstrated that the instrument can provide a new method for retrieving
fast variations in NO and NO2 plumes.
High bacterial organic carbon uptake in the Eastern Tropical South Pacific oxygen minimum zone

Abstract. Oxygen minimum zones (OMZs) show distinct biogeochemical processes that relate to microorganisms being able to thrive under low or even absent oxygen. Microbial degradation of organic matter is expected to be reduced in OMZs, although quantitative evidence is low. Here, we present heterotrophic bacterial production (3H leucine-incorporation), extracellular enzyme rates (leucine aminopeptidase/ß-glucosidase) and bacterial cell abundance for various in situ oxygen concentrations in the water column of the Eastern Tropical South Pacific off Peru. Bacterial heterotrophic activity in the suboxic core of the OMZ (at in situ ≤ 5 µmol O2 kg−1) ranged from 0.6 to 160 µmol C m−3 d−1 and was not significantly lower than in waters of 5–60 µmol O2 kg−1. Moreover, bacterial abundance in the OMZ was slightly and leucine aminopeptidase activity even significantly higher in suboxic waters compared to the upper oxycline suggesting no impairment of bacterial organic matter degradation in the core of the OMZ. Nevertheless, high cell-specific bacterial production and extracellular enzyme rates were observed in samples from the upper or lower oxyclines corroborating earlier findings of highly active and distinct micro-aerobic bacterial communities. To assess the impact of bacterial degradation of dissolved organic matter for oxygen loss in the Peruvian OMZ, we compared diapycnal fluxes of oxygen and dissolved organic carbon (DOC) and their microbial uptake within the upper 60 m of the water column. Our data indicate bacterial growth efficiencies of 0.5–8.6 % at the upper oxycline, resulting in a high bacterial oxygen demand that can explain up to 33 % of the observed average oxygen loss over depth. Our study therewith shows that microbial degradation of DOM has a considerable share in sustaining the OMZ off Peru.

The purpose of the present work is to analyze the SOCIMIs (Real estate listed investment trusts in Spain), its performance and its potential as a diversification asset between June 2014 and December 2017. The tax advantages they offer, the main incentive for the creation of these types of companies, are bringing about an increase in development of real estate investment in Spain, which is behind other developed markets where they are generally called REITs (Real Estate Investment Trusts). First, the characteristics, operation, evolution in the market, portfolios and shareholders’ composition are studied. Next, the analysis shows high performance levels measured by the modified Sharpe Ratio and the Jensen’s Alpha for the main SOCIMIs on the market as well as a high portfolio diversification potential demonstrated by the Markowitz Efficient Frontier Model. SOCIMIs are characterized by being less risky investments than the market in general. Compared to traditional Real estate listed companies on the continuous market, SOCIMIs show better performance and lower levels of risk and, in general, all the companies studied –SOCIMIs and traditional Real estate listed companies- can be defined as defensive investments, less risky than the market.

AS COM(POSIÇÕES) DO PROFESSOR-ARTISTA-PESQUISADOR: DAS VIAS DE FORMAÇÃO À PERFORMANCE PROFESSORAL
Authors:   Universidade Estadual de Maringá, Cordeiro Anyelle Caroline
Published: June 2019

Esse artigo almeja analisar e convidar à reflexão de alguns aspectos do professor-artista-pesquisador e sua composição. Apresentam-se traços comparativos entre a essência contemporânea de Arte e do “ser professor-artista” baseado em Capra e Loponte, e a proposição de Nóvoa quanto à “posição do professor”. Entrelaço alguns modos de formação continuada nas dimensões de pesquisa e extensão, inserções profissionais em vias formais e não formais de educação com práticas desenvolvidas nos espaços da Universidade Estadual de Maringá e comunidade externa, buscando analisar a questão da “performance”, fundamentada em Castanheira e Schechner. Aborda-se também o cenário das Políticas Públicas que atravessam as interfaces de “professor”, “artista” e “pesquisador” no ano de 2018. Conclui-se ser modos de ação política as múltiplas vias de atuação em consonância com os processos formativos, e atualização dos modos de performar a identidade profissional, que equivale ao exercício de encontrar estratégias de posicionamento professoral, social, e político.

Published: June 2019

Background: This study assessed uptake of the Oncotype DX 21-gene assay over time and characterized which sociodemographic and clinical factors are associated with test uptake among women with lymph node−positive (LN+), hormone receptor−positive, HER2-negative breast cancer. Methods: Invasive breast cancer cases diagnosed in 2010 through 2013 were included from a SEER database linked to 21-gene assay results performed at Genomic Health’s Clinical Laboratory. Factors associated with 21-gene assay uptake were identified using a multivariable logistic regression model. Results: Uptake of the 21-gene assay increased over time and differed by race, socioeconomic status (SES), and age. In the multivariable model, when clinical and SES variables were controlled for, racial differences in test uptake were no longer observed. Private insurance status was associated with higher odds of 21-gene assay uptake (Medicaid vs private insurance: adjusted odds ratio, 0.86; P=.02), and high area-level SES was associated with an increased odds of uptake (quintile 5 vs 1: adjusted odds ratio, 1.6; P<.001). Demographic factors such as age and marital status influenced test uptake, and use varied greatly by geographic region. Uptake of the 21-gene assay increased over time and preceded the assay’s inclusion in the NCCN Guidelines for LN+ breast cancer. Differences in uptake by race, SES, and age have persisted over time. However, when clinical and SES variables were controlled for, racial differences in assay uptake were no longer observed. Socioeconomic variables, such as health insurance type and area-level SES, were associated with assay uptake. Conclusions: Future research should continue to document practice patterns related to the 21-gene assay. Given variation in testing associated with area-level SES, insurance coverage, and geographic region, interventions to understand and reduce differential uptake are needed to ensure equitable access to this genomic test.
