Oral health, oral follow-up and infectious risk management of rheumatoid arthritis patients on anti-TNF drugs: a survey of a French e-cohort

Abstract Background As periodontitis is a recognized risk factor for rheumatoid arthritis (RA), it should be adequately treated before the initiation of biologic disease-modifying antirheumatic drugs (bDMARDs), along with any concomitant acute oral infection. bDMARDs remains a co...

TESS Observations of Stochastic Low-frequency Variability in Extreme Helium Stars

Abstract Extreme helium stars (EHes) are low-mass hydrogen-deficient stars thought to be the products of double white dwarf mergers. Despite prolonged ground-based observations, there is no consensus on the properties of their photometric variability. In this article, we present...

Integrated transcriptomic and proteomic analysis reveals innate and adaptive immune dynamics in systemic autoinflammatory diseases

Systemic autoinflammatory diseases (SAIDs) are a diverse group of rare disorders with partially overlapping clinical features. However, their genetic makeup and treatment responses vary widely. Although inflammasome dysregulation is central to many SAIDs, recent studies suggest t...

Detectability of Forced ENSO Changes Under Global Warming: Insights From the Recharge Oscillator

Abstract We use perfect‐model, large‐ensemble nonlinear Recharge Oscillator (RO) simulations to quantify ENSO internal variability and the detectability of forced changes in ENSO characteristics. Fixed‐parameter simulations show that linear trends in ENSO standard deviation, peri...

Gut virome instability in HSCT

The gut virome remains one of the least resolved components of the human microbiome, limiting interpretation of how viral communities shape intestinal injury and recovery. Hematopoietic stem cell transplantation (HSCT), particularly in the allogeneic setting, offers an informativ...

Imaging the Alpine Collision With Seismic Radial Anisotropy

Abstract The Alpine region and the adjacent Northern Apennines (NA) and Northern Dinarides record the complex tectonic evolution associated with the collision between the Eurasian and Adriatic plates. We combine Rayleigh and Love surface waves from ambient noise and earthquake da...

Episodic super-Eddington accretion as a clue to Overmassive Black Holes in the early Universe

Abstract Early JWST observations are providing growing evidence for a ubiquitous population of accreting supermassive black holes (BHs) at high redshift, many of which appear overmassive compared to the empirically-derived local scaling relation between black hole mass and host g...

The effect of augmented protein intake on nitrogen balance: A nested cohort study of the TARGET protein trial

Purpose The impact of augmenting enteral protein delivery on nitrogen balance, urea generation, and kidney function in critically ill patients remains poorly defined. This study aimed to investigate these effects in a nested cohort within the TARGET Protein trial. Methods We cond...

Effective integration of Lie type algebras

Abstract This is a short survey on the recent developments made in the integration theory with effective formulas of algebraic structures stronger or higher than Lie algebras. This article is part of the theme issue ‘Derived Lie algebras in geometry and topology’.

Global propagation of analyticity and unique continuation for semilinear waves

In this article, we develop a new method to prove both global propagation of analyticity and unique continuation in finite time for solutions of semilinear wave-type equations with analytic nonlinearity. It combines control theory techniques and Galerkin approximation, inspired b...

Multi-analytical study of the effects of secondary working and recycling in Roman glass

The impact of secondary processing and recycling on the composition and redox equilibrium in archaeological glass remains difficult to assess. This paper reports the results of a multi-analytical study of glass finds from a Roman villa in southwestern France, revealing varying mi...

Urbanisation and habitat loss favour thermophilic and monogynous ant species

Environmental changes such as urbanisation and related habitat loss and fragmentation profoundly impact ecological communities by altering habitats, resources, and microclimates. Yet, the impacts of the resulting environmental conditions on metacommunity dynamics, ranging from sp...

Quantification of absolute IgG concentration in bat sera

Abstract Bats are endowed with a remarkable capacity to withstand important pathogens through evolutionary adaptations in their immune systems. Antibodies are essential component of the adaptive immune response and serve as a crucial biomarker, indicating both present and past pa...

Metabolic Dysfunction–Associated Steatotic Liver Disease: An Underrated and Emerging Cardiovascular Risk Factor

Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most prevalent chronic liver disease worldwide and is increasingly recognized as a major contributor to cardiovascular morbidity and mortality. Beyond liver involvement, MASLD represents a systemic metabolic...

Lie structures in homotopy and isotopy calculi

Abstract We establish compatibility of Lie structures that appear in homotopy calculus of functors and isotopy calculus of embeddings. On one hand, we give a new proof of the Johnson–Arone–Mahowald result describing the layers of the Goodwillie tower of the identity functor, and...

Take a Break, Take Notes? The Relationship Between Pauses, Note-Taking, and Learning Performance in Instructional Videos

Although pauses in instructional videos can enhance learning, previous studies have shown that learners barely use this function. However, these studies have not examined the role of note-taking in pause use. This study investigated whether note-taking is associated with pause us...

Post launch spectral and radiometric performances of MAJIS, the VIS-NIR imaging spectrometer of JUICE

Abstract. The post-launch spectral and radiometric performances of MAJIS, the VISNIR imaging spectrometer of the ESA Jupiter Icy Moon Explorer (JUICE), have been evaluated using observations performed during the Lunar-Earth Gravitational Assist (LEGA) of 19–20 August 2024 and obs...

ODIN: Confirmation and 3D Reconstruction of Six Massive Protoclusters at Cosmic Noon

Abstract Protoclusters represent sites of accelerated galaxy formation and extreme astrophysical activity characteristic of dense environments. Identifying massive protoclusters and mapping their spatial structures are therefore crucial for understanding how large-scale environme...

Pinwheels in symplectic rational and ruled surfaces and non‐squeezing of rational homology balls

Abstract We use almost toric fibrations and the symplectic rational blow‐up to determine when certain Lagrangian pinwheels, which we call liminal , embed in symplectic rational and ruled surfaces. The case of ‐pinwheels, namely Lagrangian , answers a question of Kronheimer in the...

The rod bipolar cell pathway contributes to surround responses in OFF retinal ganglion cells

Abstract Sensory neurons can be influenced by stimuli beyond their receptive field center, yet the mechanisms underlying this surround modulation remain poorly understood. In the retina, many OFF ganglion cells exhibit responses to ON stimulation outside their receptive field cen...
