Abstract
We describe the discovery of a solar neighborhood (d = 468 pc) binary system with a main-sequence sunlike star and a massive noninteracting black hole candidate. The spectral energy distribution of the visible star is described by a single stellar model. We derive stellar parameters from a high signal-to-noise Magellan/MIKE spectrum, classifying the star as a main-sequence star with T

⊙. The spectrum shows no indication of a second luminous component. To determine the spectroscopic orbit of the binary, we measured the radial velocities of this system with the Automated Planet Finder, Magellan, and Keck over four months. We show that the velocity data are consistent with the Gaia astrometric orbit and provide independent evidence for a massive dark companion. From a combined fit of our spectroscopic data and the astrometry, we derive a companion mass of

⊙. We conclude that this binary system harbors a massive black hole on an eccentric (e = 0.46 ± 0.02), 185.4 ± 0.1 day orbit. These conclusions are independent of El-Badry et al., who recently reported the discovery of the same system. A joint fit to all available data yields a comparable period solution but a lower companion mass of

Abstract
We report the confirmation of three exoplanets transiting TOI-4010 (TIC-352682207), a metal-rich K dwarf observed by the Transiting Exoplanet Survey Satellite in Sectors 24, 25, 52, and 58. We confirm these planets with the High Accuracy Radial velocity Planet Searcher for the Northern Hemisphere radial velocity observations and measure their masses with 8−12% precision.

Radial velocity observations also reveal a super-Jupiter-mass companion called TOI-4010 e in a long-period, eccentric orbit (P ∼ 762 days and e ∼ 0.26 based on available observations). TOI-4010 is one of the few systems with multiple short-period sub-Saturns to be discovered so far.
A Data-driven, Physics-based Transport Model of Solar Energetic Particles Accelerated by Coronal Mass Ejection Shocks Propagating through the Solar Coronal and Heliospheric Magnetic Fields

Published: June 2023

Abstract
In an effort to develop computational tools for predicting radiation hazards from solar energetic particles (SEPs), we have created a data-driven physics-based particle transport model to calculate the injection, acceleration, and propagation of SEPs from coronal mass ejection (CME) shocks traversing through the solar corona and interplanetary magnetic fields. The model runs on an input of corona and heliospheric plasma and magnetic field configuration from a magnetohydrodynamic model driven by solar photospheric magnetic field measurements superposed with observed CME shocks determined from coronagraph images. SEP source particles are injected at the shock using the result of diffusive shock acceleration formulation from a characteristic obliquity-dependent injection from a heated solar wind thermal tail population. With several advanced computation techniques involving stochastic simulation and integration, the model obtains the particle intensity at any location in interplanetary space through the rigorous solution to the time-dependent 5D focus transport equation in the phase space that includes perpendicular diffusion. We apply the model to the 2011 November 3 CME event. The calculation results reproduce multispacecraft SEP observations at Earth and STEREO-B reasonably well without normalization of particle flux. The observations at STEREO-A can be reproduced by rescaling particle energy or modified energy dependence of particle diffusion coefficients. This circumsolar SEP event seen by spacecraft at Earth, STEREO-A, and STEREO-B at widely separated longitudes can be explained by diffusive shock acceleration by a single CME shock with a moderate speed.
The Behavior of Bp He-weak Stars in the Far UV—Paper VI: HD 21699
Authors: Monier Richard 
Published: June 2023

Abstract
The analysis of spectra of the B8 He-weak Si star HD 21699 recorded by the SWP camera on board the International Ultraviolet Explorer in 1987 reveals large amplitude variations of the far-ultraviolet spectral energy distribution over a time interval of about four days in 1987 October. In contrast, the level of the mid-UV flux did not vary between phases of FUV flux maximum and minimum which suggests that changes of the silicon continuous and line opacity play an important role in the variations. The lines of C iv doublet near 1550 Å are stronger and have an extended blue wing at phase of far-UV maximum. The optical brightness recorded by the Fine Error Sensor on board IUE is probably anticorrelated with the FUV flux, reflecting the redistribution of the FUV flux toward longer wavelengths.
Un « marchandage » maussien ? L’accumulation par le don dans l’économie numérique
Authors: Fourcade Marion , Kluttz Daniel N. 
Published: June 2023

La collecte de données sur les personnes, les organisations et les choses et leur transformation en une forme de capital est souvent décrite comme un processus d’« accumulation par dépossession », une perte généralisée de droits renforcée par des pratiques prédatrices et la violence juridique. Pourtant, cet argument ne cadre pas avec le fait que l’inscription dans les systèmes numériques est souvent vécue (et présentée par les entreprises) comme un processus beaucoup plus bénin : s’inscrire à un service « gratuit », répondre à l’invitation d’un « ami » ou être encouragé à « partager » du contenu. Dans cet article, nous nous concentrons sur le rôle central du don et de la réciprocité dans le modèle commercial et l’imaginaire culturel du capitalisme numérique. Nous suggérons que la relation économique qui se développe à la suite d’une offre de cadeau numérique ne masque pas seulement l’asymétrie structurelle entre le donneur et le receveur, mais permet également la création d’une nouvelle marchandise, les données personnelles, obscurcit sa véritable valeur et naturalise son appropriation privée. Nous appelons ce régime unique « l’accumulation par le don ».

Le projet avorté de constitution au Chili consacre une notion importante : celle de bien commun naturel. Cette contribution vise à comprendre l’intérêt de cette notion en mettant en évidence les limites des régimes de propriétés privée et publique et à dégager les caractères de cette notion émergente à travers deux projets conférant une personnalité morale à des entités naturelles, le fleuve Whanganui en Nouvelle-Zélande et la lagune de Mar Menor en Espagne.
L’associatisme médiéval au-delà des enclosures. À l’origine des communs, des collectivités territoriales et de l’ESS
Authors: Draperi Jean-François 
Published: June 2023

Les communs sont définis ici comme des groupements de personnes s’engageant volontairement et solidairement dans le gouvernement de biens. On distingue deux ensembles de communs médiévaux : les communs d’habitants et les communs de métiers. Ils sont, pour l’essentiel, reconnus juridiquement, édifient un mode économique et instituent un mode de vie. Ces traits expliquent qu’ils aient en partie survécu aux enclosures. Nous définissons les communs d’habitants au Moyen Âge (1) avant de montrer leur actualité à travers deux exemples, la vallée du Queyras et la Confédération suisse (2). Nous présentons ensuite les communs de métiers (3), et exposons les liens entre ces communs et l’économie sociale et solidaire contemporaine. Cette inscription dans la durée permet de définir le concept l’associatisme.
Désenclaver l’histoire des Communs de l’histoire de l’État des Modernes. Associations syndicales de propriétaires entre « droit social » et « domestication administrative »
Authors: Ingold Alice 
Published: June 2023

Le sort des Associations syndicales invite à écrire une autre histoire de la tension entre pluralité sociale et pouvoir centralisé à la charnière entre XIX e et XX e siècles. Le devenir de ces associations syndicales après 1789 interroge très directement la manière dont le collectif a été pensé après la Révolution. Je montre comment Maurice Hauriou, dans son célèbre commentaire de l’arrêt pour l’Association syndicale du canal de Gignac, en 1899, ne peut concevoir ces syndicats hors d’un monde binaire opposant collectif et public, économique et politique. Trente ans plus tard, Georges Gurvitch voit dans ces mêmes associations syndicales l’expression d’un « droit social » spontané, issu donc de la créativité normative de la société, mais « annexé par l’État ». Ce jugement de Gurvitch est formulé en 1932, au terme donc d’une évolution de ces structures syndicales qui aurait confirmé leur « domestication administrative » – annoncée par Hauriou en 1899. Mes recherches montrent que ces organisations collectives n’ont pas tant été des institutions « hybrides », à la frontière du public et du privé, pour reprendre les termes d’Hauriou, que des organisations collectives qui ne se laissent précisément pas enfermer dans cette partition binaire, soit du côté de la logique privée contractuelle, soit du côté d’un droit public. Ces institutions ont précisément bousculé ce partage en train d’être consolidé par l’ordre étatique entre privé et public, dans une partition binaire où l’État s’est accaparé la capacité à dire le plus qu’un. J’appelle à désenclaver l’histoire de ces communs en restituant l’historicité de l’avènement de l’État des Modernes, qui a précisément sommé ces dispositifs collectifs de basculer soit du côté du civil et du contractuel, soit du côté du public et de l’administratif. Bref, je veux restituer ici l’hétérogénéité d’une vie collective qui ne se réduit ni à la coordination de droit privé, ni au droit public.
The Anxiolytic and Antidepressant Effect of Stachys lavandulifolia in the Experimental Pentylenetetrazole-Induced Rat Model of Acute Seizure

Published: June 2023

Abstract

Objective
In traditional medicine, Stachys lavandulifolia or mountain tea has been used in the treatment of arthritis and rheumatoid arthritis. A leaf extract from this plant is also thought to be effective in treating epilepsy as well as other neurological ailments. To assess the effect of S. lavandulifolia extract (SLE), rats were exposed to a stress and anxiety model caused by seizures.

Materials and Methods
A challenge dose of pentylenetetrazole (PTZ) (60 mg/kg) was used to induce seizures in male Wistar rats (200–250 g). Animal treated with an intraperitoneal injection of either SLE (50 mg/kg) or sodium valproate (100 mg/kg) alone or in combination 30 min before PTZ challenge. The effect of stress and anxiety was assessed using an open field test (OFT), forced swim test (FST), and elevated plus maze (EPM). At the end of the experiment, anesthesia was used to euthanize rats, and their blood serum was collected for measurements of glutathione (GSH), malondialdehyde (MDA), and GSH peroxidase (GPx).

Results
In contrast to the control group, those treated with PTZ exhibited depressive behavior. At 50 mg/kg, SLE provided protection against seizures induced by PTZ. SLE also reduced seizure-induced stress and anxiety, significantly improving FST, EPM, and OFT compared with the PTZ-treated group. By decreasing MDA levels and restoring the antioxidant enzymes GSH and GPx, SLE treatment protects against seizure-induced anxiety and stress.

Conclusions
SLE inhibits oxidative stress damage and seizure-induced stress by inhibiting seizures’ inhibitory effects.

Published: June 2023

Abstract

Background:
Inflammatory bowel disease (IBD) disk is an easy tool to use in clinical practice to measure IBD-related disability, with a score >40 correlating with high daily-life burden. Its use has been limited mainly to the western world. We aimed to estimate the prevalence of IBD-related disability and evaluate the associated risk factors in Saudi Arabia.

Methods:
In this cross sectional study conducted at a tertiary referral center for IBD, the English IBD disk was translated into Arabic, and patients with IBD were approached to complete it. Total IBD disk score (0 = no disability; 100 = severe disability) was documented and a score of >40 was set as a threshold to estimate the prevalence of disability.

Results:
Eighty patients with a mean age of 32.5 ± 11.9 years and disease duration of 6 years, including 57% females, were analyzed. The mean IBD-disk total score was 20.70 ± 18.69. The mean subscores for each function within the disk ranged from 0.38 ± 1.69 for sexual functions to 3.61 ± 3.29 for energy. The overall prevalence of IBD-related disability was 19% (15/80 scoring >40) and was much higher in active disease, in males and in IBD of long duration (39%, 24%, and 26%, respectively). A clinically active disease, high CRP, and high calprotectin were strongly associated with higher disk scores.

Conclusion:
Although the overall mean IBD disk score was low, nearly 19% of our population had high scores signifying a high prevalence of disability. As demonstrated by other studies, active disease and high biomarkers were significantly associated with higher IBD-disk scores.
Implementation of risk-sharing agreements in Saudi Arabia: Comparison and reflection on the NICE Model
Authors: Abu-Shraie Nada , Alhammad Ali , Balkhi Bander , Al-Jedai Ahmed 
Published: June 2023

In recent years, healthcare spending has increased, due to factors such as aging population, lifestylebased diseases, and high-cost health technologies. These factors have put enormous pressure on policymakers to curtail costs and shift towards value-based healthcare system. In this system, drug companies must demonstrate the value of their products in real-world settings. However, evidence may not be available at the time of product launch, leading to delays in reimbursement decisions and access of patients to products. To address this gap, risk-sharing agreements (RSA) have been introduced between manufacturers and payers. The most common type of RSA is the financial-based agreement which may take various forms such as annual sales caps, price-volume agreements, and comparator rebates. These agreements allow for rapid access to innovative medications. Another type of RSA is the outcome-based agreement which ties reimbursement to the real-world outcomes of products. These agreements are more complex, but they are expected to grow rapidly with the availability of real-world data. In the Middle East, the use of RSA is limited, although it is expected to increase with the ongoing shift towards a value-based healthcare system and introduction of health technology assessment. Saudi Arabia is leading these efforts in the region. This study was aimed at describing the current status of RSAs, trends in utilization of RSAs, and challenges of RSA implementation in Saudi Arabia (KSA). Real-world examples of RSAs in various healthcare sectors are also provided. Overall, the use of RSA facilitates access to innovative medications while ensuring value for money and efficient utilization of limited healthcare resources
Quyu Xiaozhong recipe exerts anti-inflammatory effect in acute mastitis by inhibiting TLR4/NF-κB signal pathway
Authors: Wang Mingzheng , Jin Li 
Published: June 2023

Purpose: To investigate the effect of Quyu Xiaozhong recipe (QYXZR) on acute mastitis induced by Staphylococcus aureus in rats via TLR4/NF-κB signal pathway.
Methods: The rat model of acute mastitis was constructed by injecting Staphylococcus aureus into the fourth pair of nipples of rats 5-7 days after parturition. The rats were treated with drugs 12 h after injection. Pathological changes in rat mammary tissue were determined using hematoxylin-eosin (H&E) staining. Myeloperoxidase (MPO) kit was used to evaluate MPO activity. Enzyme-linked immunosorbent assay (ELISA) was employed to determine the levels of inflammatory factors, while changes in protein expression of TLR4, NF-κB-p65, and IκB-α were determined by Western blot.
Results: QYXZR intervention significantly attenuated pathological damage in rats and alleviated Staphylococcus aureus-induced mastitis. At the same time, QYXZR significantly reduced the expression of MPO and the levels of inflammatory factors (p < 0.05). Further molecular mechanistic studies revealed that QYXZR exerted anti-inflammatory effects by inhibiting TLR4/NF-κB signal pathway.
Conclusion: QYXZR alleviates acute mastitis caused by Staphylococcus aureus via the inhibition of TLR4/NF-κB pathway, thus, providing the scientific and theoretical basis for the extensive use of this traditional Chinese medicine in the treatment of acute mastitis.
