Current state-of-the-art spectrographs cannot resolve the fundamental spatial (subarcseconds) and temporal (less than a few tens of seconds) scales of the coronal dynamics of solar flares and eruptive phenomena. The highest-resolution coronal data to date are based on imaging, which is blind to many of the processes that drive coronal energetics and dynamics. As shown by the Interface Region Imaging Spectrograph for the low solar atmosphere, we need high-resolution spectroscopic measurements with simultaneous imaging to understand the dominant processes. In this paper: (1) we introduce the Multi-slit Solar Explorer (MUSE), a spaceborne observatory to fill this observational gap by providing high-cadence (<20 s), subarcsecond-resolution spectroscopic rasters over an active region size of the solar transition region and corona; (2) using advanced numerical models, we demonstrate the unique diagnostic capabilities of MUSE for exploring solar coronal dynamics and for constraining and discriminating models of solar flares and eruptions; (3) we discuss the key contributions MUSE would make in addressing the science objectives of the Next Generation Solar Physics Mission (NGSPM), and how MUSE, the high-throughput Extreme Ultraviolet Solar Telescope, and the Daniel K Inouye Solar Telescope (and other ground-based observatories) can operate as a distributed implementation of the NGSPM. This is a companion paper to De Pontieu et al., which focuses on investigating coronal heating with MUSE.

In the lower solar coronal regions where the magnetic field is dominant, the Alfvén speed is much higher than the wind speed. In contrast, the near-Earth solar wind is strongly super-Alfvénic, i.e., the wind speed greatly exceeds the Alfvén speed. The transition between these regimes is classically described as the “Alfvén point” but may in fact occur in a distributed Alfvén critical region. NASA’s Parker Solar Probe (PSP) mission has entered this region, as it follows a series of orbits that gradually approach more closely to the Sun. During its 8th and 9th solar encounters, at a distance of ≈16 R
⊙ from the Sun, PSP sampled four extended periods in which the solar wind speed was measured to be smaller than the local Alfvén speed. These are the first in situ detections of sub-Alfvénic solar wind in the inner heliosphere by PSP. Here we explore properties of these samples of sub-Alfvénic solar wind, which may provide important previews of the physical processes operating at lower altitude. Specifically, we characterize the turbulence, anisotropy, intermittency, and directional switchback properties of these sub-Alfvénic winds and contrast these with the neighboring super-Alfvénic periods.
A Novel Way of Measuring the Gas Disk Mass of Protoplanetary Disks Using N2H+ and C18O

Published: February 2022

Measuring the gas mass of protoplanetary disks, the reservoir available for giant planet formation, has proven to be difficult. We currently lack a far-infrared observatory capable of observing HD, and the most common gas mass tracer, CO, suffers from a poorly constrained CO-to-H2 ratio. Expanding on previous work, we investigate if N2H+, a chemical tracer of CO-poor gas, can be used to observationally measure the CO-to-H2 ratio and correct CO-based gas masses. Using disk structures obtained from the literature, we set up thermochemical models for three disks, TW Hya, DM Tau and GM Aur, to examine how well the CO-to-H2 ratio and gas mass can be measured from N2H+ and C18O line fluxes. Furthermore, we compare these gas masses to gas masses independently measured from archival HD observations. The N2H+(3 − 2)/C18O(2 − 1) line ratio scales with the disk CO-to-H2 ratio. Using these two lines, we measure 4.6 × 10−3
M
⊙ ≤ M
disk ≤ 1.1 × 10−1
M
⊙ for TW Hya, 1.5 × 10−2
M
⊙ ≤ M
disk ≤ 9.6 × 10−2
M
⊙ for GM Aur and 3.1 × 10−2
M
⊙ ≤ M
disk ≤ 9.6 × 10−2
M
⊙ for DM Tau. These gas masses agree with values obtained from HD within their respective uncertainties. The uncertainty on the N2H+ + C18O gas mass can be reduced by observationally constraining the cosmic-ray ionization rate in disks. These results demonstrate the potential of using the combination of N2H+ and C18O to measure gas masses of protoplanetary disks.
X-Ray Chronicles of Alpha Centauri: The Swooning of α Cen B
Authors: Ayres Tom
Published: February 2022

The central AB binary of Alpha Centauri has been visited regularly by Chandra X-ray Observatory since late 2005. Up to mid-2020, the B component, an early K dwarf, had traced out a relatively smooth 8 yr coronal (T ∼ 2 MK) activity cycle. Recently, however, B’s X-ray count rate suddenly dipped, from cycle maximum levels to near minimum in just 16 months. Previous cycle decays were 3–4 yr. The significance of the swoon remains to be seen.
The Line Variability of 78 Vir (A2p SrCrEu) in the Mid-ultraviolet
Authors: Monier Richard
Published: February 2022

Line variations are studied in the mid-ultraviolet spectra of 78 Vir collected with IUE between phases of far-UV (FUV) maximum and FUV minimum. The mid-UV spectrum of 78 Vir is populated with low-lying transitions of iron-peak elements. The lines of Cr ii and Ca ii are found to be stronger at phase of FUV minimum, while the lines of Ni 
ii
probably vary in anti phase with those of chromium and calcium. Those of Fe 
ii
and Mn 
ii
do not show convincing variations between the two phases. The analysis of these mid-ultraviolet spectra suggests that iron and manganese are uniformly distributed over the surface of 78 Vir, while chromium, calcium and nickel are not but more ultraviolet lines should be studied to confirm this.
Evaluation of Recent Measurements of Mercury’s Moments of Inertia and Tides Using a Comprehensive Markov Chain Monte Carlo Method
Authors: Goossens Sander , Renaud Joe P. , Henning Wade G. , Mazarico Erwan , Bertone Stefano , Genova Antonio
Published: February 2022

Recent estimates of Mercury’s rotational state yield different obliquity values, resulting in normalized polar moment of inertia values of either 0.333 or 0.346. In addition, recent measurements of Mercury’s tidal response, as expressed by its Love number k
2, are higher than previously reported. These different measurements have implications for our understanding of Mercury’s interior structure. We perform a comprehensive analysis of models of Mercury’s interior structure using a Markov Chain Monte Carlo approach, where we explore models that satisfy the various measurements of moments of inertia and mean density. In addition, we explore models that either have Mercury’s tidal response as a measurement or predict its tidal response. We find that models that match the lower polar moment value also fit or predict the recent, higher Love number. Models that match the higher polar moments predict Love numbers even higher than current estimates. For the resulting interior structure models, we find a wide range of viscosities at the core–mantle boundary, including low values that could be consistent with the presence of partial melt, with higher viscosities also equally allowed in our models. Despite the possibility of low viscosities, our results do not show a preference for particularly high temperatures at the core–mantle boundary. Our results include predicted values for the pressure and temperature of Mercury’s core, and the displacement Love numbers.
Europa’s Surface Water-ice Crystallinity and Correlations between Lineae and Hydrate Composition
Authors: Berdis Jodi R. , Murphy James R. , Chanover Nancy J.
Published: February 2022

Europa’s surface composition and evidence for cryovolcanic activity can provide insight into the properties and composition of the subsurface ocean, allowing the evaluation of its potential habitability. One promising avenue for revealing the surface processing and subsurface activity are the relative fractions of crystalline and amorphous water-ice observed on the surface, which are influenced by temperature, charged particle bombardment, vapor deposition, and cryovolcanic activity. The crystallinity observed on Europa’s leading hemisphere cannot be reproduced by thermophysical and particle flux modeling alone, indicating that there may be additional processes influencing the surface. We performed a spectral mixture analysis on hyperspectral image cubes from the Galileo Near-Infrared Mapping Spectrometer (NIMS) to identify how surface crystallinity is influenced by physical processing at a high spatial resolution scale. We focus specifically on two image cubes, 15e015 closer to the equator and 17e009 closer to the south pole, both on the leading hemisphere. We performed a nonnegative least-squares spectral mixture analysis to reveal both the non-ice composition and the water-ice crystallinity of the surface. We found that amorphous water-ice dominates the spectrum at the equator and the south pole. We estimated a mean crystallinity of ∼35% within the 15e015 NIMS cube and a mean crystallinity of ∼15% within the 17e009 NIMS cube, which is consistent with ground-based spectroscopically derived crystallinities. We also identified a correlation of magnesium sulfate, magnesium chloride, and hydrated sulfuric acid with lineae and ridges, which may provide evidence for surface processing by upwelling subsurface material.
Noachian Proglacial Paleolakes on Mars: Regionally Recurrent Fluvial Activity and Lake Formation within Closed-source Drainage Basin Craters
Authors: Boatwright Benjamin D. , Head James W.
Published: February 2022

A body of geologic evidence suggests that Noachian-aged craters on Mars were modified primarily by runoff from rainfall in a warm and wet early Mars climate. Although melting and runoff of frozen water ice have been suggested as plausible alternatives, supporting geomorphic evidence of Noachian glaciation on Mars has been elusive. We previously identified a Noachian-aged crater in the southern highlands that contained evidence of glacially derived fluvial and lacustrine features but was hydrologically disconnected from its surroundings. This closed-source drainage basin (CSDB) crater and proglacial paleolake provided the first candidate evidence of Noachian cold-based glaciation on Mars. Here, we describe a second nearby CSDB crater that contains similar evidence of glacial melting leading to the formation of proglacial fluvial channels and paleolakes on the crater floor. This new evidence suggests that CSDB formation was occurring episodically at regional scales throughout the Late Noachian and into the Early Hesperian. Recurrent episodes of glacial melting are consistent with climate model predictions of a cold and icy early Mars highlands with limited melting of glacial ice during periods of punctuated warming.

Published: February 2022

Background/Aims: The obesity paradox has been known in end-stage renal disease (ESRD). However, the effect of body mass index (BMI) or waist circumference (WC) prior to percutaneous coronary intervention (PCI) on the development of ESRD is not clear.Methods: Using nationally representative data from the Korean National Health Insurance System, we enrolled 140,164 subjects without ESRD at enrolment who underwent PCI between 2010 and 2015, and were followed-up until 2017. Patients were stratified into five levels based on their baseline BMI and six levels based on their WC with 5-cm increments. BMI and WC were measured at least 2 years prior to PCI. The primary outcome was the development of ESRD.Results: During a median follow-up of 5.4 years, 2,082 (1.49%) participants developed ESRD. The underweight group (hazard ratio [HR], 1.331; 95% confidence interval [CI], 0.955 to 1.856) and low WC (< 80/< 75) (HR, 1.589; 95% CI, 1.379 to 1.831) showed the highest ESRD risk and the BMI 25 to 30 group showed the lowest ESRD risk (HR, 0.604; 95% CI, 0542 to 0.673) in all participants after adjusting for all covariates. In the subgroup analysis for diabetes mellitus (DM) duration, WC < 85/80 cm (men/women) increased ESRD risk in only the DM group (DM < 5 years and DM ≥ 5 years) compared to the reference group (85–90/80–85 of WC), but not the normal or impaired fasting glucose group.Conclusions: Low WC prior to PCI showed an increased ESRD risk in patients with DM undergoing PCI as compared to those without DM.

To estimate the health-promoting effects of Lacticaseibacillus paracasei (previously Lactobacillus casei) strain Shirota (LcS) that reached the lower gastrointestinal tract alive, we investigated the characteristics of gut microbiome, organic acid profiles, defecatory symptoms and serum viral antibody indexes of healthy Japanese adults between the group in whom live LcS was detected or not from stool. The β-diversity index of the gut microbiome constituted a significant difference between the live-LcS-detected-group (LLD) and the live-LcS-not-detected-group (LLnD). In the LLD, the Bifidobacteriaceae, Lactobacillaceae, and Coriobacteriaceae counts were significantly higher, and the succinate concentration was significantly lower than that in the LLnD. The serum herpes simplex virus (HSV) immunoglobulin (Ig)M antibody index in the LLD tended to be lower than that of the LLnD in HSV IgG-positive subjects. Of the LLD, those in the fermented milk products containing LcS (FML)-high-frequency-group (FML-HF) and those in the FML-low-frequency-group (FML-LF) had different gut microbiome and organic acid profiles. However, the pattern of differences between FML-HF and FML-LF was dissimilar those between LLD and LLnD. In contrast, among subjects with FML-LF, those in the group with LLD in stool (LF-LLD) and those in the LLnD in stool (LF-LLnD) showed a similar pattern of differences in their gut microbiome and organic acid profiles as those in the LLnD and LLD. The LLD and LF-LLD commonly had lower caloric and carbohydrate intakes from the diet than their respective control groups. In this study, we found that the presence of live LcS in stool is associated with a healthy gut environment and inhibition of the reactivation of latently infected viruses in the host. However, these health-promoting effects on the host were not related to the frequency of FML intake. Furthermore, dysbiosis of the gut microbiome and diet including caloric intake was related to the viability of ingested LcS in the gut.
Diet in the Prevention of Dementia
Authors: Gregorevic Kate
Published: February 2022

Many cases of dementia can be delayed or prevented with lifestyle interventions. One important strategy is optimizing nutrition. Nutrition plays a role by providing essential micro- and macronutrients, but also by optimizing gut health via the gut microbiome. There is no one optimal diet for brain health; the key is eating a large variety of plant-based foods and ensuring that the diet contains all necessary micronutrients. There is a need for further research in this area to look beyond the European context.

Role of Diet in Depression in Young People: Recommendations for Implementation in Practice
Authors: Yung Alison R. , Hockey Meghan , Grosman Adam , Rocks Tetyana
Published: February 2022

Childhood and adolescence are vulnerable periods for development of a depressive disorder, with potentially lifelong negative consequences. Research increasingly suggests that lifestyle practices, including diet, are an effective adjunct strategy for the management of poor mental health. Dietary improvements are now recommended as the first actionable step in the treatment of depression in adults. In young people, evidence is also suggestive of a link between diet and mental health. However, implementing dietary interventions in youth can be challenging owing to numerous barriers. This paper reviews the literature on the topic and proposes several strategies that could be used by mental health clinicians to address diet as part of their practice.

Retinal Detachment Repair With Vitrectomy: Air Tamponade Integration to a Vitreoretinal Service, Comparison With Gas Tamponade, and Literature Review
Authors: Moussa George , Mathews Namita , Makhzoum Osama , Park Dong Young
Published: February 2022

BACKGROUND AND OBJECTIVE:

Rhegmatogenous retinal detachment (RRD) repair by pars plana vitrectomy and gas tamponade (GT) has significant clinical and quality-of-life impacts compared with repair by short-acting air tamponade (AT). With AT, most authors minimize cryotherapy because of prolonged chorioretinal scar formation and use perfluorocarbon to maximize subretinal fluid drainage; this deviates from traditional technique, which discourages popularization of AT.

PATIENTS AND METHODS:

Prospective 12-month study from January to December 2019 of all primary macula-on RRD cases. Patients fulfilling the inclusion criteria for the Pneumatic Retinopexy Versus Vitrectomy for Retinal Detachment Trial received AT and otherwise were assigned to receive GT.

RESULTS:

Forty-six patients were enrolled: 22 (48%) receiving AT and 24 (52%) receiving GT. The primary success rate of AT was 21 (95%) and the primary success rate of GT was 23 (96%), with 100% final success. Cryopexy was used in 64% of AT cases and 58% of GT cases. Cataract surgery was required less when AT was used (1 [6%]) than when GT was used (3 [21%]). AT was used in 48% of primary macula-on RRD and 27% of all primary RRD cases.

CONCLUSIONS:

AT has visual and anatomical outcomes comparable to those of GT with conventional vitrectomy techniques, with faster postoperative rehabilitation enabling a swift return to normal daily activities.

Published: February 2022

The advent of large volumes of Sargassum sp. on the Mexican Caribbean coast has become an emerging issue for the Mexican population. The most frequent action is harvesting, but a correct treatment or energy recovery strategy is still missing. This work aimed to evaluate the energy potential of Sargassum fluitans, through elemental calculations and direct measurements, considering the effect of its washing. The calorific value determined by the direct method was 9.24 ± 0.28 MJ/kg and 12.64 ± 0.18 MJ/kg for dirty and washed Sargassum, respectively. The washing effect increased the calorific values in Sargassum fluitans by 36.80%. The washing effect increased the calorific values determined by indirect methods, increasing 10.10% and 41.04%, each method, respectively. The content of toxic metals was lower in both materials than that established for non-woody biomass from energy use, concerning the ISO 17225:2014 standard. The unit energy cost of Sargassum fluitans is ＄0.007 and ＄0.011 per MJ for dirty and washed conditions, respectively. Finally, the results of this work indicate that the Sargassum wash provides better characteristics to be considered an alternative fuel option in combustion systems such as thermo-electric plants (based on carbon), sugar mills, and cement kilns with co-processing of solid waste. Attending from a bioenergetic approach, Sargassum's emerging seasonal problem affects the Mexican Caribbean coast.

Some physical phenomena were described through fractional differential equations and compared with integer-order differential equations which have better results, which is why researchers of different areas have paid great attention to study this direction. So, in this manuscript, we discuss the existence and uniqueness of solutions to a system of fractional deferential equations (FDEs) under Riemann-Liouville (R-L) integral boundary conditions. The solution method is obtained by two basic rules, the first rule is the Leray-Schauder alternative and the second is the Banach contraction principle. Finally, the theoretical results are supported by an illustrative example.

Introduction

Neck and back pain afflicts millions of people. Magnetotherapy has shown to have anti-inflammatory effects that could act on pain generation, but the literature lacks provide a precise therapeutic protocol.

Methods

A high-intensity electromagnetic field with a dedicated applicator was administered to 38 patients with low-back pain and 30 patients with neck pain. The device provides 60 mT and a frequency of 50 Hz for 30 minutes, the session was repeated 4 times.

Results

The mean VAS of the low-back pain group decreased from 6.56 to 4.54, with a significant reduction of 30.8%. The mean VAS of the neck pain group decreased from 6.51 to 1.96, with a significant reduction of 69.9%.

Discussion

The treatment used showed good results in both groups of the patient, without side effects. The therapeutic protocol adopted is safe, provide rapid relief from the pain and is not time demanding. This treatment could represent an effective non-pharmacologic physical therapy option in the treatment of low-back pain and cervical pain.

Le Raid Paris-New York... en cinématographie. Traces d’adaptations « apparemment délibérées » dans le catalogue américain de la Star Film
Authors: Gizzi Fernandino
Published: February 2022

Cet article tente de vérifier et de démontrer que le contrôle direct de l’exportation et de la distribution de la production cinématographique méliésienne aux États-Unis, à partir de 1903, s’est accompagné d’une volonté et d’un effort d’adaptation au système de connaissances, aux goûts (réels ou présumés) et aux sensibilités plus profondément culturelles du public américain. De ces variations transatlantiques – pour lesquelles il n’est pas toujours facile, voire possible, de distinguer entre les différentes mains (ou intelligences) de la maison méliésienne responsables de leur choix et de leur application – le catalogue américain de 1908 porte la plupart des indices et des traces. Elles s’appuient sur une considération du spectateur (conçu dans toutes ses différentes réalités) que l’on rencontre habituellement dans la pratique cinématographique de Méliès, et se construisent à travers le recours à des stratégies rhétoriques ou matérielles. Ainsi, leur prise en compte nous permettra de réfléchir une fois de plus et d’un point de vue différent sur la nature instable et jamais définitive, de l’objet cinématographique des premiers temps.

Application of Metaheuristic Approaches for the Variable Selection Problem
Authors: Song Myung Soon , Vasko Francis J. , Lu Yun , Callaghan Kyle
Published: February 2022

Variable selection is an old topic from regression models. Besides many conventional approaches, some metaheuristic approaches from the realm of optimization such as GA (Genetic Algorithm) or simulated annealing have been suggested to date. These methods have a considerable advantage to deal with many problems over the classical methods, but they must control relevant fine-tuning parameters associated with cross-over or mutation, which can be difficult and time-consuming. In this paper, Jaya, one of several parameter-free approaches will be suggested and explored. Several metaheuristic methods will be compared using results from a real-world dataset and a simulated dataset. The impact of using local search will be analyzed.
A-Memory Garden
Authors: Bergamo Marilia Lyra
Published: February 2022

This paper presents the artwork “A-Memory Garden” and explores its potential according to the groundworks of the poetics of complexity. In poetics of complexity, there is an artist's desire to create perceptions about the relationship between individuals and the result of those interactions to arouse the sense of complexity. The paper presents an overview of the artwork developed, information about its adopted technology, and the artist's intentions. Also, it presents an end-user analysis of the artwork and a discussion of its complexity qualification. This analysis contributes to a perception of the artwork not only through the users' point of view but also for the potential of individual narratives that can emerge by the agency within a complex system. This combination between what is perceived by the user and the narratives of the computational agents in “A-Memory Garden” validates the artwork as a poetics of complexity.
A Line of Movement
Authors: Saque Cibele , Valente Antonio Costa
Published: February 2022

Surrounded by a plant world that seems to reserve a particular space for change and action, the authors highlight the line element, which seems to play, among others, the role of a bridge between different areas of knowledge. Its structuring and transversal nature implies itself in drawing as a means of aesthetic exploration, branching out its presence in concepts of the synthesis of information, the study of movement, and always in the paths of the word “observation.” Combining visual and perceptive acuity with the power of graphic and formal synthesis of the line, through studies of movement of this involving exploratory space, particular attention is given to lines of support and oscillation of movement through the dynamic progression that models formal development. This reflection seeks to contemplate a potential of the study of the dynamic line to signal observation, understanding of the world (namely from the vegetal development), and its implications in animation cinema.

Published: February 2022

Social media has become one of the most important sources in understanding opinion of people regarding important and trending topics. One such topic was the Supreme Court’s verdict on almost seven-decade old Ayodhya land dispute case. On 9th November 2019, the apex court ordered that the disputed land in question be used for construction of Ram Temple. As it was one of the most anticipated judgements in India’s history, Twitter, was buzzing long before the date of verdict. To perform sentiment analysis, around 70,000 tweets pertaining to the verdict were collected from 26th Oct 2019 to 23rd Nov 2019. The dataset was then divided into three phases i.e., pre-verdict, on day of verdict and post-verdict and NRC Lexicon has been used to analyze the results and extract positive, negative, and neutral tweets. Sentiment analysis of each phase indicates that the verdict has been accepted by the public.

Published: February 2022

Multipath Transmission Control Protocol (MPTCP) is a transport layer protocol, which transmits TCP segments on more than one path, in multihomed devices. It was designed with the aim of Bandwidth aggregation and redundant connections. Currently, multihomed devices have wireless interfaces of heterogeneous nature. MPTCP is not able to give its optimal performance in heterogeneous networks. This paper presents an experimental performance study of four different schedulers, namely Roundrobin, Default, Blest, and Redundant. Our testbed comprises Ethernet, LTE, and Wifi networks to connect multihomed devices. We have compared the scheduler performance in terms of Throughput , Download time and path utilization rate in homogenous and heterogenous scenarios . Results showed that Round robin provides optimal throughput in homogenous networks and also performs bandwidth aggregation by utilizing both the paths but fails to perform in heterogenous networks. Blest, provides best throughput among the four schedulers but prefers fast path only.

Published: February 2022

This purpose of this study is to develop a wearable technology model (WTM) by identifying key determinants of wearable technology adoption (comfort, safety, privacy, data accuracy, portability, and design, perceived usefulness, and perceived ease of use). Wearable technologies (WT) are Internet enabled technologies that are rapidly emerging and gaining popularity. WT refers to clothing or accessories that are enabled with minicomputers and sensors and are meant to be worn on the human body for an extended period of time to enhance their daily lives. Results indicate the most important factors that users care about when intending to use wearable technology ranked from most to least important are design, data accuracy, portability, comfortability, PU, PEOU, safety, and privacy of the device to be worn. This study develops the WTM, a novel model that is tested and validated specifically to examine user’s intentions to adopt WT, and to extend the traditional technology acceptance models. This study proves the WTM can be applied successfully to examine user’ s intentions to adopt WT.

Information technology (IT) services are indispensable in the enterprises' sustainability program nowadays. For the outsourcing of IT services, many companies use the contract service model and set up a project to implement timely IT requests which constantly arrive at different IT sites. The demand for outsourced IT services and related workforce coordination is a permanent decisional process, yet existing studies mainly focus on the one-time assignment or the centralized service model. Hence, this paper bases on the multi-period and multi-service allocation requirement to develop a sustainable assignment model. The model handles continuous service requests and decentralized worker assignments to optimize overall costs under the fixed-price contract type of IT service. A real industrial service case is reported to illustrate the model. A comparative review with related works is also provided to discuss the contributions of the model and to outline its future research and development.

STAT4 plays a critical role in the generation of both innate and adaptive immune responses. In the absence of STAT4, Th1 responses, critical for resistance to fungal disease, do not occur. Infection with the dimorphic fungus, Coccidioides, is a major cause of community-acquired pneumonia in the endemic regions of Arizona and California. In some people and often for unknown reasons, coccidioidal infection results in hematogenous dissemination and progressive disease rather than the typical self-limited pneumonia. Members of three generations in a family developed disseminated coccidioidomycosis, prompting genetic investigation. All affected family members had a single heterozygous base change in STAT4, c.1877A>G, causing substitution of glycine for glutamate at AA626 (STAT4E626G/+). A knockin mouse, heterozygous for the substitution, developed more severe experimental coccidioidomycosis than did wild-type mice. Stat4E626G/+ T cells were deficient in production of IFN-γ after anti-CD3/CD28 stimulation. Spleen cells from Stat4E626G mice showed defective responses to IL-12/IL-18 stimulation in vitro. In vivo, early postinfection, mutant Stat4E626G/+ mice failed to produce IFN-γ and related cytokines in the lung and to accumulate activated adaptive immune cells in mediastinal lymph nodes. Therefore, defective early induction of IFN-γ and adaptive responses by STAT4 prevents normal control of coccidioidomycosis in both mice and humans.

Mucosal-associated invariant T (MAIT) cells are innate-like lymphocytes that recognize microbial vitamin B metabolites and have emerging roles in infectious disease, autoimmunity, and cancer. Although MAIT cells are identified by a semi-invariant TCR, their phenotypic and functional heterogeneity is not well understood. Here we present an integrated single cell transcriptomic analysis of over 76,000 human MAIT cells during early and prolonged Ag-specific activation with the MR1 ligand 5-OP-RU and nonspecific TCR stimulation. We show that MAIT cells span a broad range of homeostatic, effector, helper, tissue-infiltrating, regulatory, and exhausted phenotypes, with distinct gene expression programs associated with CD4+ or CD8+ coexpression. During early activation, MAIT cells rapidly adopt a cytotoxic phenotype characterized by high expression of GZMB, IFNG and TNF. In contrast, prolonged stimulation induces heterogeneous states defined by proliferation, cytotoxicity, immune modulation, and exhaustion. We further demonstrate a FOXP3 expressing MAIT cell subset that phenotypically resembles conventional regulatory T cells. Moreover, scRNAseq-defined MAIT cell subpopulations were also detected in individuals recently exposed to Mycobacterium tuberculosis, confirming their presence during human infection. To our knowledge, our study provides the first comprehensive atlas of human MAIT cells in activation conditions and defines substantial functional heterogeneity, suggesting complex roles in health and disease.

Aim:

The aim of this study was to investigate the relation of high-sensitive cardiac troponin T (hs-cTnT) elevation with characteristics of supraventricular tachycardia (SVT) episode (duration and maximum heart rate) and coronary computed tomography angiography (CCTA) findings in patients with SVT who presented to the emergency room with palpitation.

Methods:

This retrospective, single-center, noninvasive study included all patients aged between 18 years and 65 years who presented to the emergency department due to narrow-complex SVT and underwent CCTA to rule out coronary artery disease (CAD) due to elevation of hs-cTnT and reverted back to sinus rhythm after intravenous adenosine. The first, second, and the maximum hs-cTnT levels were obtained from the database. The patients were classified into normal coronaries, nonobstructive CAD, and obstructive CAD according to findings of the CCTA. The findings of the groups were compared.

Results:

Eighty-five patients were enrolled in the study. Of them, 21 (26%) patients were female. Sixty-three patients (74%) had normal coronary arteries as per CCTA results, whereas 22 patients (22%) had nonobstructive CAD and two patients (2%) had obstructive CAD. The groups did not differ statistically in respect to hs-cTnT measurements, duration of the arrhythmia, and maximum heart rate at SVT episode. There was no significant statistical correlation between hs-cTnT and the study parameters except the maximum heart rate.

Conclusion:

Cardiac troponins may increase in patients with paroxysmal SVT irrespective of the presence of coronary lesions, and the CCTA may not be an appropriate investigation in the differential diagnosis of paroxysmal SVT with elevated hs-cTnT.

Takayasu arteritis is a chronic multisystem vasculitis which has been known to be associated with myriad of ophthalmological manifestations. Steroids and immunomodulators are the mainstay of medical management in early stages of disease. We report the case of a 15-year-old girl with complaints of diminution of vision in both the eyes. Her ophthalmic examination suggested a diagnosis of Takayasu retinopathy with posterior ischemic optic neuropathy in her left eye and ocular ischemic syndrome in the right eye. Digital subtraction angiography revealed a significant narrowing of major vessels originating from the arch of aorta and the left vertebral artery. She underwent left subclavian artery and left vertebral artery balloon angioplasty followed by left vertebral artery stenting. Her vision improved significantly postprocedure, suggesting that endovascular intervention in the later stages of disease is a promising treatment modality for Takayasu retinopathy.
Ali je nova ureditev volilnih okrajev za državnozborske volitve ustavna?
Authors: Rogelj Boštjan
Published: February 2022

Državni zbor RS je februarja 2021 sprejel novelo zakona, ki določa volilne enote in volilne okraje, uporabljene za državnozborske volitve. Novela minimalno spreminja ureditev, za katero je Ustavno sodišče RS leta 2018 ugotovilo, da je neustavna. V raziskavi smo preverili, v kolikšni meri nova ureditev izpolnjuje zakonska merila in odpravlja neustavno stanje. Primerjalna analiza, v katero sta poleg stare in nove ureditve vključena še dva predloga ureditve volilnih okrajev, ki ju je leta 2019 oblikovala strokovna skupina, kaže več pomanjkljivosti nove ureditve. Ta sicer odpravlja problem velikostno najbolj izstopajočih volilnih okrajev, ne rešuje pa problema njihove geografske nezaokroženosti. Posledično se lahko zgodi, da bo nova ureditev znova predmet ustavne presoje.

Published: February 2022

In this paper, we analyze the importance of Kocen’s atlases for the development of Croatian school cartography. Comparing German and Croatian editions in the period between 1887 and 1943, we follow the progress in map printing, cartographic techniques, language redactions of toponymy as well as the inclusion of thematic maps and the influence of political discourse (German centralism vs. Slavic nationalisms) on the geographical scope and content of maps used in the educational process.

Published: February 2022

Zmanjševanje regionalnih razvojnih razlik in uravnotežen razvoj, temelječ na načelih trajnostnega razvoja, sta osrednja cilja regionalne politike v Sloveniji, zato v članku preučujemo uspešnost slovenskih regij pri doseganju teh ciljev na socialno-ekonomskem in okoljskem področju po letu 2010. V ta namen so bili preučeni štirje sintezni kazalniki (bruto domači proizvod na prebivalca, ekološki odtis na prebivalca, indeks razvojne ogroženosti in kazalnik trajnostnega regionalnega razvoja) in 32 posameznih ekonomskih, socialnih in okoljskih kazalnikov, ki so vključeni tudi v izračun kazalnika trajnostnega regionalnega razvoja. Večina ekonomskih in socialnih kazalnikov kaže približevanje strateškim razvojnim ciljem, večina okoljskih pa oddaljevanje od njih.
