Breast cancer is a type of cancer in the breast tissue that is common in women. An effort to detect the possibility of breast cancer early is to do a Breast Self-Examination (BSE), no need to spend money, just enough to take a moment. The purpose of this study was to determine the effect of demonstration and audiovisual counseling on breast self-examination (BSE) skills in women of childbearing age. This type of research is a quasi-experimental with a two group pretest-posttest design. The population in this study were all women of childbearing age and the number of samples in this study was 66 people (33 people each with demonstration and audiovisual methods) who were taken by total sampling technique. Collecting data using observation sheets or checklists. This research test uses the Wilcoxon Signed Rank Test statistical test. The results showed that the Z value = -5.477 and p-value = 0.000 (p-value <0.05), indicating that there was an effect of counseling demonstration methods on BSE skills and the Z value = -5,000 and p-value = 0.000, indicating that there was an effect of audiovisual counseling on BSE skills. It is hoped that women of childbearing age can improve their knowledge and skills in performing breast self-examination by seeking more information that is easy to understand, such as through videos and pictures to practice BSE at home and also to reduce the incidence of breast cancer in women who are expected to have their breasts checked at least once a month.
Accretion Disk Size Measurements of Active Galactic Nuclei Monitored by the Zwicky Transient Facility

Published: April 2022

We compile a sample of 92 active galactic nuclei (AGNs) at z < 0.75 with gri photometric light curves from the archival data of the Zwicky Transient Facility and measure the accretion disk sizes via continuum reverberation mapping. We employ Monte Carlo simulation tests to assess the influences of data sampling and broad emission lines and select out the sample with adequately high sampling cadences (3 days apart in average) and minimum contaminations of broad emission lines. The interband time delays of individual AGNs are calculated using the interpolated cross-correlation function, and then these delays are fitted with a generalized accretion disk model, in which interband time delays are a power function of wavelength, black hole mass, and luminosity. A Markov Chain Monte Carlo method is adopted to determine the best parameter values. Overall the interband time delays can be fitted with the τ ∝ λ
4/3 relation as predicted from a steady-state, optically thick, geometrically thin accretion disk; however, the yielded disk size is systematically larger than expected, although the ratio of the measured to theoretical disk sizes depends on using the emissivity- or responsivity-weighted disk radius. These results are broadly consistent with previous studies, all together raising a puzzle about the “standard” accretion disk model.

Published: April 2022

The radiation energy of X-ray pulsars is mainly concentrated in the high-energy ray bands, so processing high-energy photon signals is helpful for discovering some young and active pulsars. To quickly and accurately detect effective pulsar signals from a large number of samples within a finite observation time, an automatic identification algorithm for pulsar candidates based on X-ray observations is developed in this paper. First, the autocorrelation operation is used to improve the signal-to-noise ratio of the profile and solve the initial phase misalignment problem. Then, the candidate frequency range is expanded, and the output signal is folded according to these frequencies to obtain a series of profiles. The six statistical features of these profiles are extracted to generate frequency-feature curves. Compared with the traditional epoch folding method, the frequency-feature curves show more consistent characteristics. To improve the classification accuracy, the frequency-feature curves are converted into two-dimensional images, and ConvNets are used for deep feature extraction and classification. A simulation method based on the nonhomogeneous Poisson process is utilized to create the training set, and generative adversarial networks are used for data augmentation to solve the class imbalance problem caused by limited pulsar samples. Finally, the RXTE observation data of PSR B0531+21, PSR B0540-69, and PSR B1509-58 are selected for testing. The experimental results show that the highest recall and precision reached 0.996 and 0.983, respectively. Demonstrating the considerable potential of this method for identifying pulsar candidates based on X-ray observations.

Published: April 2022

We present coordinated observations of GRB 170202A carried out by the Zadko and the Virgin Island Robotic Telescopes. The observations started 59 s after the event trigger, and provided nearly continuous coverage for two days, due to the unique locations of these telescopes. We clearly detected an early rise in optical emission, followed by late optical flares. By complementing these data with archival observations, we show that GRB 170202A is well described by the standard fireball model if multiple reverse shocks are taken into account. Its fireball is evidenced as expanding within a constant-density interstellar medium, with most burst parameters being consistent with the usual ranges found in the literature. The electron and magnetic energy parameters (ϵ

e
, ϵ

B
) are orders of magnitude smaller than the commonly assumed values. We argue that the global fit of the fireball model achieved by our study should be possible for any burst, pending the availability of a sufficiently comprehensive data set. This conclusion emphasizes the crucial importance of coordinated observation campaigns of gamma-ray bursts, such as the one central to this work, to answer outstanding questions about the underlying physics driving these phenomena.
Massive Galaxy Mergers Have Distinctive Global H i Profiles
Authors: Zuo Pei , Ho Luis C. , Wang Jing , Yu Niankun , Shangguan Jinyi
Published: April 2022

The global 21 cm H i emission-line profile of a galaxy encodes valuable information on the spatial distribution and kinematics of the neutral atomic gas. Galaxy interactions significantly influence the H i disk and imprint observable features on the integrated H i line profile. In this work, we study the neutral atomic gas properties of galaxy mergers selected from the Great Observatories All-sky LIRG Survey. The H i spectra come from new observations with the Five-hundred-meter Aperture Spherical Telescope and from a collection of archival data. We quantify the H i profile of the mergers with a newly developed method that uses the curve of growth of the line profile. Using a control sample of non-merger galaxies carefully selected to match the stellar mass of the merger sample, we show that mergers have a larger proportion of single-peaked H i profiles, as well as a greater tendency for the H i central velocity to deviate from the systemic optical velocity of the galaxy. By contrast, the H i profiles of mergers are not significantly more asymmetric than those of non-mergers.
Where and How Does a Decay-index Profile Become Saddle-like?
Authors: Luo Runbin , Liu Rui
Published: April 2022

The decay index of solar magnetic fields is known as an important parameter in regulating solar eruptions from the standpoint of the torus instability. In particular, a saddle-like profile of decay index, which hosts a local torus-stable regime at higher altitudes than where the decay index first exceeds the instability threshold, is found to be associated with some confined or two-step eruptions. To understand the occurrence of such a profile, we employed dipoles to emulate different kinds of photospheric flux distributions. Corroborated by observations of representative active regions, our major results are as follows: (1) in bipolar configurations the critical height increases away from the AR center along the polarity inversion line (PIL) and its average is roughly half of the centroid distance between opposite polarities; (2) in quadrupolar configurations saddle-like profiles appear above the PIL when the two dipoles oriented in the same direction are significantly more separated in this direction than in the perpendicular direction, and when the two dipoles are oriented differently or have unequal fluxes; and (3) saddle-like profiles in quadrupolar configurations are associated with magnetic skeletons such as a null point or a hyperbolic flux tube, and the role of such profiles in eruptions is anticipated to be double-edged if magnetic reconnection is involved.

Published: April 2022

Introduction: The use of a signal-to-cut-off ratio has been recommended by the Centre for Disease Control and Prevention to determine the need for further validation using a supplemental test. In this study, we aimed to determine the optimal true-positive signal-to-cut-off ratio for the ABBOTT ARCHITECT i2000SR immunoassay (Abbott Laboratories, Illinois, USA), using the Serodia® HCV particle agglutination (HCV-PA) assay (Fujirebio Inc, Tokyo, Japan) as the reference test for anti-HCV screening.

Methodology: We analysed a total of 13,240 specimens using the ARCHITECT i2000SR immunoassay and subsequently subjected all the reactive specimens with a signal-to-cut-off ratio ≥ 1.00 (n = 267) to the Serodia® HCV-PA reference assay. Receiver operating characteristic (ROC) curve analysis was carried out and performance characteristics for each signal-to-cut-off ratio were determined. The selected signal-to-cut-off ratio value was then assessed using a line immunoassay (LIA) test.

Results: ROC curve analysis determined that the optimal signal-to-cut-off ratio was 5.05, which gave the highest Youden’s Index (J) value of 0.89, with a sensitivity of 93.1% (88.9-97.2), a specificity of 96.0% (92.4-99.4), a positive predictive value of 96.4% (93.3-99.5), and a negative predictive value of 92.2% (87.5-96.8). Validation of the optimal S/Co value using the LIA test yielded an accuracy of 91.8%, with sensitivity and specificity values of 92.0% and 91.7%, respectively.

Conclusions: The optimal signal-to-cut-off ratio value for the ARCHITECT i2000SR immunoassay, which was determined using HCV-PA assay as the reference test and validated using a HCV-LIA assay, showed high sensitivity and specificity, and may be used in routine anti-HCV screening.

Published: April 2022

Introduction: Leprosy is a chronic infectious disease with many risk factors including inadequate nutrient intake and nutritional deficiencies, which affect the immune system, and influence leprosy progression.

Objectives: To elucidate the relation between the serum level of zinc, vitamin C, and selenium and the clinical spectrum of leprosy.

Methodology: A case control study included 100 leprotic patients (50 multibacillary and 50 paucibacillary) and 100 age and sex matched controls. Vitamin C was measured by ELISA, zinc was measured by using centronic colorimetric spectrophotometry, and selenium was measured by Inductivity Coupled Plasma Optical Emission Spectroscopy technique.

Results: Zinc and Vitamin C levels were significantly lower in paucibacillary (mean ± SD = 89.86 ± 20.712 and 2.52 ± 1.27 respectively) and multibacillary (mean ± SD = 81.41 ± 18.61 and 1.98 ± 0.59 respectively) than in controls (mean ± SD = 107.34 ± 3.98 and 4.95 ± 2.45 respectively) (p value < 0.001) with no significant difference between paucibacillary and multibacillary patients (p value = 0.142 and = 0.066 respectively). Selenium level showed no significant difference between the three groups (p value > 0.05) (mean ± SD = 51.27 ± 42.61 in paucibacillary, 47.54 ± 30.21 in multibacillary, and 44.07 ± 46.58 in controls).

Conclusions: Lower serum levels of zinc and vitamin C in leprosy patients may be a result of disease pathogenesis or related to the antioxidants based treatment. It might also present prior to the disease onset due to malnutrition that may have accelerated the development of leprosy.

Published: April 2022

Introduction: The clinical application of granulocyte-colony stimulating factor on chronic liver disease is still controversial. The study aimed to evaluate the effects of granulocyte-colony stimulating factor on chronic liver disease.

Methodology: A systematic literature search was performed in PubMed, Embase, Cochrane Library and Chinese Biomedical Literature database. Randomized-controlled trials assessing the efficacy of granulocyte-colony stimulating factor were selected.

Results: Granulocyte-colony stimulating factor was associated with an increasing long-term survival (RR 1.54; 95% CI 1.22 to 1.94; p = 0.0003; heterogeneity: Q = 0.26, I2 = 25%) and an increasing short-term survival (RR 1.44; 95% CI 1.16 to 1.78; p = 0.0009; heterogeneity: Q < 0.00001, I2 = 80%). Granulocyte-colony stimulating factor failed to lower mortality secondary to multiple organ failure (RR 0.65; 95% CI 0.34 to 1.21; p = 0.17; heterogeneity: Q = 0.45; I2 = 0%), gastrointestinal bleeding mortality (RR 0.97; 95% CI 0.61 to 1.56; p = 0.91; heterogeneity: Q = 0.35; I2 = 11%) and sepsis mortality (RR 0.27; 95% CI 0.06 to 1.12; p = 0.07; heterogeneity: Q < 0.00001; I2 = 90%). It significantly lowered the Child-Turcotte-Pugh (MD=−0.97, 95% CI −1.48 to −0.45; p = 0.0003; heterogeneity: Q = 0.25; I2 = 28%). No serious adverse events were observed.

Conclusions: Granulocyte-colony stimulating factor resulted in significantly improved 12-month survival and reduced Child-Turcotte-Pugh score with relative safety. Establishment of guidelines and protocols in future clinical trials will promote granulocyte-colony stimulating factor as an effective and safe therapy for chronic liver disease.
Reducing persistent coronavirus infection in bats may lower the frequency of viral spillover to humans
Authors: Nahreini Piruz , Gulati Gunsagar S
Published: April 2022

Coronaviruses have been responsible for the emergence of pathogenic human diseases in recent decades, especially the coronavirus disease of 2019 (COVID-19). Phylogenetic studies of RNA (ribonucleic acid) viruses suggest that most human coronaviruses originated in bats, which are suitable reservoir hosts for many zoonotic viruses because of their unique biological and physiological features. The generation of human pathogenic coronaviruses is a result of genetic adaptation in bats and/or intermediate hosts, leading to spillover events. Therefore, we propose that specifically reducing or disrupting persistent coronavirus infection in bats may consequently decrease the frequency of human coronavirus diseases. We suggest several strategies to achieve the aforementioned goal in bats, including vaccination and targeted delivery of molecular inhibitors, such as monoclonal antibodies, aptamers, antisense oligonucleotides, and siRNA by use of viral nanoparticles. Advances in global bat research with the aim of controlling coronavirus infection in these mammals are pivotal in enhancing human health worldwide.

Gastroesophageal reflux disease (GERD) is a condition in which gastric contents regurgitate into the esophagus or beyond, resulting in either troublesome symptoms or complications. GERD is heterogeneous in terms of varied manifestations, test findings, and treatment responsiveness. GERD diagnosis can be established with symptomatology, pathology, or physiology. Recently the Lyon consensus defined the “proven GERD” with concrete evidence for reflux, including advanced grade erosive esophagitis (Los Angeles classification grades C and or D esophagitis), long-segment Barrett’s mucosa or peptic strictures on endoscopy or distal esophageal acid exposure time > 6% on 24-hour ambulatory pH-impedance monitoring. However, some Asian researchers have different opinions on whether the same standards should be applied to the Asian population. The prevalence of GERD is increasing in Asia. The present evidence-based guidelines were developed using a systematic review and meta-analysis approach. In GERD with typical symptoms, a proton pump inhibitor test can be recommended as a sensitive, cost-effective, and practical test for GERD diagnosis. Based on a meta-analysis of 19 estimated acid-exposure time values in Asians, the reference range upper limit for esophageal acid exposure time was 3.2% (95% confidence interval 2.7-3.9%) in the Asian countries. Esophageal manometry and novel impedance measurements, including mucosal impedance and a post-reflux swallow-induced peristaltic wave, are promising in discrimination of GERD among different reflux phenotypes, thus increasing its diagnostic yield. We also propose a long-term strategy of evidence-based GERD treatment with proton pump inhibitors and other drugs.
Entweder - Oder ! Rosa Luxemburg et l’internationalisme
Authors: Löwy Michael
Published: April 2022

La plupart des discussion sur l’internationalisme radical de Rosa Luxemburg s’intéressent surtout, et parfois uniquement, à son attitude négative – en effet très discutable – envers les droits politiques des nations. Ce qui manque dans cette approche, c’est le côté positif de son point de vue, sa riche contribution à la conception marxiste de l’internationalisme prolétarien, et son refus obstiné de céder aux sirènes du nationalisme et du chauvinisme. Un internationalisme qui se traduit notamment par son refus de l’Union sacrée belliciste en 1914-1918 et son soutien aux luttes émancipatrices des peuples colonisés.
Paroles d’anciens enfants placés. Du récit de vie aux savoirs d’expérience
Authors: Pépin Marie-Claude
Published: April 2022

Le placement d’un enfant dans un établissement médico-social, quelles qu’en soient les raisons, provoque chez lui un bouleversement qu’il va tenter d’apprivoiser tout au long de sa vie d’adulte. Du déni à l’exposition publique, de la honte à la valorisation, c’est dans une démarche personnelle ou collective qu’il va trouver des issues favorables à son épanouissement. Une évolution du milieu médico-social et de la formation offre depuis quelques années une alternative avec la valorisation des savoirs d’expérience et la participation des anciens accompagnés à l’accompagnement de leurs pairs et aux dispositifs de formation des professionnels concernés.
L’expérience aidante ou le soutien de « ceux qui vivent » ou de « ceux qui savent »
Authors: Guillon Aurélie , Beurel Steven
Published: April 2022

L’expérience de l’autre, le fait de pouvoir partager un vécu peut devenir un soutien, une aide. C’est en partant de ce postulat que des structures médico-sociales développent des temps de rencontre entre les aidants mais aussi entre pairs. La relation à l’autre ayant partagé ce vécu fait alors écho. C’est au travers de rencontres de parents ou encore de temps d’échanges entre jeunes accompagnés dans les structures et « anciens dehors » que l’on observe l’expérience qui devient aidante.

Identités transitoires : réflexions psychanalytiques sur les identités transgenres
Authors: Lemma Alessandra
Published: April 2022

La capacité des transgenres à intégrer toutes les différences entre les sexes et les préférences sexuelles est devenue un puissant moyen d’activisme et d’identification personnelle. Moins qu’un indice de marginalité, le « trans » est devenu un marqueur culturel central. Dans cet article, je soutiendrai que cette étiquette d’identité englobe une gamme complexe de positions psychiques internes en relation avec des préférences sexuelles et des identifications de genre consciemment déclarées. Mon but est d’explorer ce qui peut sembler dans certains cas être une adhésion prématurée au potentiel d’autonomisation de l’identification transgenre à travers mon travail avec des jeunes de moins de 18 ans qui cherchent une intervention médicale pour dysphorie de genre. Cela peut miner le travail psychique douloureux nécessaire pour établir ce que signifie le transgenre pour un jeune donné. Dans une culture ambiante où la question « pourquoi le transgenre » (par opposition à « comment le transgenre ») est perçue comme pathologique, travailler avec ces jeunes gens peut s’avérer difficile pour l’analyste. Le défi consiste à tracer la frontière à égale distance d’un dialogue fondé sur une curiosité, d’une recherche du sens et de la fonction, qui est au cœur d’une approche analytique, et une attitude de « suspicion éclairée » qui n’est pas susceptible de favoriser un dialogue productif.
La vocation politique chez Aron : de la sociologie du charisme à la phénoménologie de l’ambition
Authors: Carré Alexis
Published: April 2022

La science peut-elle informer la décision politique ? Peut-elle comprendre l’objet politique sans se mettre à la place de celui qui décide ? La position d’Aron sur ces questions s’est forgée au travers d’une confrontation critique avec l’œuvre de Weber. Selon lui, loin de seulement fournir le critère d’une méthode rigoureuse, la neutralité axiologique contient une philosophie implicite qui, poussée jusque dans ses conséquences ultimes, aboutit à une politique nihiliste. Parce qu’il refusait une telle politique, Aron a tâché de réconcilier la compréhension de la réalité politique avec la nécessité du jugement moral, la tâche de la science et celle de la décision politique. Cette démarche se manifeste particulièrement dans sa pensée de la gouvernance et de la nation.

The number of arthroplasty procedures has been rising at a significant rate, contributing to a notable portion of the nation's health care spending. This growth has contributed to an increase in the number of health care economic studies in the field of adult reconstruction surgery. Although these articles are filled with important information, they can be difficult to understand without a background in business or economics. The goal of this review is to define the common terminology used in health care economic studies, assess their value and benefit in the context of total joint arthroplasty, and highlight shortcomings in the current literature.

The gastrointestinal effects amongst Ehlers-Danlos syndrome, mast cell activation syndrome and postural orthostatic tachycardia syndrome
Authors: Wong Sammi , Hasan Sara , Parducci Christina , Riley Bernadette Ann
Published: April 2022

Ehlers-Danlos syndrome (EDS), mast cell activation syndrome, and postural orthostatic tachycardia syndrome are a triad of comorbid conditions that can occur simultaneously in many patients. Specifically, Ehlers-Danlos syndrome is a group of inherited connective tissue disorders that weakens the connective tissue and causes easy bruising. Mast cell activation syndrome (MCAS) is a condition in the connective tissue of vascularized organs that causes recurrent episodes of anaphylactic symptoms. The irregular activation of mast cells may contribute to immunological manifestations in EDS patients. Postural orthostatic tachycardia syndrome (POTS) is an autonomic nervous system disorder characterized by orthostatic intolerance. Review of the literature suggests an overlap of gastrointestinal (GI) symptoms such as nausea and abdominal pain, hernias, perforations, and more. Thus, this paper will delineate each condition's distinct gastrointestinal symptoms and explore similar gastrointestinal relationships among these conditions.

In present study, the Boussinesq equation is obtained by means of the Sardar Sub-Equation Technique (SSET) to create unique soliton solutions containing parameters. Using this technique, different solutions are obtained, such as the singular soliton, the dark-bright soliton, the bright soliton and the periodic soliton. The graphs of these solutions are plotted for a batter understanding of the model. The results show that the technique is very effective in solving nonlinear partial differential equations (PDEs) arising in mathematical physics.

Dans cette étude, nous analyserons les rapports annuels d'Amnesty International 2016/17, 2017/18 et 2019, dans leurs versions anglaise, française et italienne (deux langues stratégiques, une tactique), afin de montrer les stratégies discursives déployées par Amnesty International dans les différentes langues pour affirmer la nécessité de respect des droits humains fondamentaux et les périls qui guettent leur existence même dans les contextes où l’ONG opère. À la suite d’une présentation générale de ces stratégies discursives et argumentatives dans les trois langues, nous nous pencherons plus dans le détail sur celles utilisées pour nommer (ou ne pas nommer, en poursuivant en cela une stratégie de généralisation, suivant différents moyens selon la langue utilisée) certaines minorités ethniques, religieuses et sociales considérées comme « vulnérables » (Abbas et al., 2019) et dont cette organisation se propose de sauvegarder les droits fondamentaux.Nous nous proposons donc de montrer comment ces nominations et expressions circulent dans les discours traduits, à savoir, leurs cooccurrences, leurs cotextes, leurs emplois et les éventuels écarts de sens entre les différentes versions des rapports.
No kids, more life? Du souci environnemental au sein des communautés childfree
Authors: Roux Sébastien , Figeac Julien
Published: April 2022

À partir de l’ethnographie en ligne de communautés childfree et du traitement lexicographique de publications choisies, l’article étudie l’évolution des discours sur la vie sans enfant dans l’espace anglophone. Depuis une dizaine d’années, les arguments écologiques rencontrent un écho croissant au sein des pages et groupes étudiés. Longtemps structuré par l’opposition entre une infertilité subie et une volonté affirmée de non-parentalité, l’espace childfree s’ouvre de plus en plus aux positions dites « anti-natalistes » qui font de la réduction de la population un objectif politique et/ou une position éthique. Ni malédiction, ni opportunité, la vie sans enfant devient pour certains une décision altruiste et rationnelle, s’imposant pour faire face à l’imminence de la catastrophe écologique. En caractérisant ces arguments et leur diffusion, l’article interroge le sens de discours qui font de la vie sans enfant moins un empêchement que l’expression d’un autre rapport au monde et à la population.
An Empirical Study to Examine Drivers of Personal Cloud Computing Usage
Authors: Changchit Chuleeporn , Cutshall Robert , Changchit Charles
Published: April 2022

Cloud computing is recognized as an important area for information technology (IT) innovation and investment. Many companies are rapidly reorienting their overall IT strategies to include cloud computing. Cloud computing reduces the cost of IT since there is no installing, maintaining, or updating software as well as the elimination of IT emergencies or working after hours. Despite the potential for positive change, there are still other factors to consider before cloud computing can be accepted entirely by the individual, large business, or academic group. Therefore, the main objective of this study is to examine how individuals perceive cloud computing. The study findings reveal several factors which play an important role in their decision whether to adopt cloud computing technology. This study will contribute to the literature by proposing and empirically testing factors that impact the intention to adopt cloud computing.

Published: April 2022

This work aims to document a two-sided impact of the COVID-19 pandemic on online question and answer communities. It implements empirical analyses on subsidiary communities affiliating to the Stack Exchange network. Using a difference-in-difference approach to identify the impact of the pandemic on community volume (the counts of questions and answers) and responsiveness (the likelihood of questions to be answered), this work has the following discoveries. First, the community volume grows, both in questions and answers, driven by a prolonged time of staying at home during the pandemic. Second, the community responsiveness declines, driven by an influx of new community members during the pandemic, which is also a result of the prolonged time of staying at home. Theoretical and practical implications are discussed.

This study contributes to assessing sharing economy concepts such as sustainability, organizational efficiency, and stakeholder engagement, and develops business-to-business sharing drivers in a hierarchical structure. Job shop production systems are challenged by demand fluctuation and low production capacity. This study adopted the fuzzy Delphi method to arrive at a valid set of attributes and a fuzzy decision-making trial and evaluation laboratory to address the proposed attributes’ relationships. The results show that stakeholder engagement and technological performance are important causal aspects, and economic benefits act as a mediating aspect that drives the perceived organizational utility in JPS. The top causal criteria were identified as outsourced labor services, information sharing, digital platforms, workplace vitality, new technologies, and cost efficiency. These criteria provide a practical solution for managers with which to improve B2B sharing practices in JPS.

Several unique waves of γδ T cells are generated solely in the fetal/neonatal thymus, whereas additional γδ T cell subsets are generated in adults. One intriguing feature of γδ T cell development is the coordination of differentiation and acquisition of effector function within the fetal thymus; however, it is less clear whether this paradigm holds true in adult animals. In this study, we investigated the relationship between maturation and thymic export of adult-derived γδ thymocytes in mice. In the Rag2pGFP model, immature (CD24+) γδ thymocytes expressed high levels of GFP whereas only a minority of mature (CD24−) γδ thymocytes were GFP+. Similarly, most peripheral GFP+ γδ T cells were immature. Analysis of γδ recent thymic emigrants (RTEs) indicated that most γδ T cell RTEs were CD24+ and GFP+, and adoptive transfer experiments demonstrated that immature γδ thymocytes can mature outside the thymus. Mature γδ T cells largely did not recirculate to the thymus from the periphery; rather, a population of mature γδ thymocytes that produced IFN-γ or IL-17 remained resident in the thymus for at least 60 d. These data support the existence of two populations of γδ T cell RTEs in adult mice: a majority subset that is immature and matures in the periphery after thymic emigration, and a minority subset that completes maturation within the thymus prior to emigration. Additionally, we identified a heterogeneous population of resident γδ thymocytes of unknown functional importance. Collectively, these data shed light on the generation of the γδ T cell compartment in adult mice.

Asthma is a common and ubiquitous chronic respiratory disease that is associated with airway inflammation and hyperreactivity resulting in airway obstruction. It is now accepted that asthma is controlled by a combination of host genetics and environment in a rather complex fashion; however, the link between sensing of the environment and development and exacerbation of allergic lung inflammation is unclear. Human populations expressing cosegregating D299G and T399I polymorphisms in the TLR4 gene are associated with a decreased risk for asthma in adults along with hyporesponsiveness to inhaled LPS, the TLR4 ligand. However, these data do not account for other human genetic or environmental factors. Using a novel mouse strain that expresses homologous human TLR4 polymorphisms (TLR4-single nucleotide polymorphism [SNP]), we directly tested the effect of these TLR4 polymorphisms on in vivo responses to allergens using two models of induction. We report that intact TLR4 is required for allergic inflammation when using the OVA and LPS model of induction, as cellular and pathological benchmarks were diminished in both TLR4-SNP and TLR4-deficent mice. However, in the more clinically relevant model using house dust mite extract for induction, responses were enhanced in the TLR4-SNP mice, as evidenced by greater levels of eosinophilic inflammation, Th2 cytokine production, and house dust mite–specific IgG1 production compared with wild-type mice; however, mucus production and airway hyperreactivity were not affected. These results suggest that the TLR4 polymorphic variants (genes) interact differently with the allergic stimulation (environment).
Groupes de Coxeter finis: involutions et cubes
Authors: Serre Jean-Pierre
Published: April 2022

We review the properties of the finite Coxeter groups which are most useful for applications to cohomological invariants, namely their classes of involutions and their “cubes”, i.e., their abelian subgroups which are generated by reflections.

Pour l’étude des invariants cohomologiques des groupes de Coxeter finis, il est utile d’avoir une description détaillée de leurs involutions et des sous-groupes abéliens qu’elles engendrent.
Compactifications of horospheric products
Authors: Forghani Behrang , Mallahi-Karai Keivan
Published: April 2022

We define and study a new compactification, called the height compactification of the horospheric product of two infinite trees. We will provide a complete description of this compactification. In particular, we show that this compactification is isomorphic to the Busemann compactification when all the vertices of both trees have degree at least three, which also leads to a precise description of the Busemann functions in terms of the points in the geometric compactification of each tree. We will discuss an application to the asymptotic behavior of integrable ergodic cocycles with values in the isometry group of such horospheric product.
Cartel screening – can competition authorities and corporations afford not to use big data to detect cartels?
Authors: Beth Hannes , Gannon Oliver
Published: April 2022

Competition authorities have recently placed an increasing emphasis on developing screening tools to pro-actively detect cartels through the analysis of procurement data. In light of this development, this article reviews the economics behind such screening tools together with strategic considerations for corporations seeking to develop and implement similar tools. Owing to their access to data and the known recent development of screens by competition authorities, the authors believe that, if corporations become active screeners, they could effectively contribute to the deterrence and detection of cartels. This should be in their own interest to do so as well. As part of the development and application of such screening tools, a close cooperation between competition authorities and corporations is advocated for each party to exchange experiences and to mutually benefit from the results of well-functioning screens.

Introduction. Speech disorders (SD) are one of the urgent problems of childhood neurology. Despite the long history of studying speech disorders in children, the use of modern instrumental research in the diagnosis, the use of various therapeutic techniques for their correction, scientific interest in understanding the pathogenetic foundations of these disorders remains relatively high. In recent years, much attention has been paid to studying the genetic causes of the development of this pathology. Currently, data are presented on more than 20 candidate genes that may determine isolated speech disorders or their combination with other cognitive disorders. The study of the molecular and genetic foundations of speech disorders in children will expand clinicians’ understanding of the pathogenesis of speech disorders and optimize diagnostic approaches. The aim of the study is to investigate the structure of SD and diseases and to define clinically significant nucleotide variants leading to various diseases, the phenotype of which includes SD. Materials and methods. One hundred sixty 2 to 7-year children with speech disorders aged were under observation, 93 (58.1%) girls and 67 (41.9%) boys were hospitalized into the Department of Neuropsychiatry and psychosomatic pathology and the Department of Pathology of early Childhood of the of National Medical Research Center for Children’s Health of the Ministry of Health of Russian Federation. All observed patients underwent sequencing of the clinical exome by mass parallel sequencing. Results. Sequencing the clinical exome in SD children makes it possible to detect clinically significant nucleotide variants leading to various diseases, including speech disorders. The most common speech disorders in children are clinical manifestations of hereditary diseases. In 5 (3.1%) of the observed patients, nucleotide variants were found during a molecular genetic study that can cause diseases in which speech and intellectual-mnestic disorders are among the main clinical manifestations. Conclusion. There were studied molecular genetic features of speech disorders in 160 children. The continuation of clinical studies aimed at searching for pathogenic genome variants leading to speech and intellectual-mnestic disorders in a representative sample of patients with speech disorders will resolve the issue of the feasibility of including sequencing of the clinical exome in the diagnostic algorithm of speech disorders in children.
Justicia epistémica y participativa en el acceso sanitario de las mujeres de comunidades Mapuce. La atención sanitaria de partos
Authors: Rodríguez Cintia Daniela
Published: April 2022

Este artículo propone un análisis en clave geosituada de la atención sanitaria de las mujeres de comunidades indígenas mapuce en Argentina, desde el marco de la justicia epistémica y participativa. En un primer momento, se caracterizan las concepciones que estas comunidades tienen respecto a la salud-enfermedad y sus modos de vivir el momento de parto. En un segundo momento, se pone en evidencia la violencia específica a la que son sometidas las mujeres mapuce en la atención de partos por parte del modelo médico hegemónico cuando no contemplan sus saberes ancestrales y sus modos de parir. Finalmente, se ofrecen reflexiones respecto a la necesidad de repensar el sistema público sanitario con el claro objetivo de promover un enfoque de derechos humanos, centrado en una atención sanitaria intercultural e interepistémica. En la conclusión se consideró de suma relevancia partir de la narración de las luchas y resistencias desde la propia voz de estas mujeres, para atender a un acercamiento más situado respecto a los relatos de las experiencias vivenciales que las mujeres mapuce describieron sobre las características de la atención sanitaria que reciben. En este aspecto, se pudieron constatar diversas situaciones de violencia obstétrica y cultural desde el propio accionar del sistema sanitario hegemónico. En efecto, se sostiene que es imperativo construir puentes que amplíen las horizontalidades epistémicas y la democratización de la democracia.
