A Reproducible MRI‐Based Pipeline for Longitudinal Tracking of Laser‐Assisted Bioprinted Cells in Three‐Dimensional Constructs

ABSTRACT Laser‐assisted bioprinting (LAB) enables precise spatial patterning of living cells within three‐dimensional constructs; however, the lack of non‐destructive, standardised methods for longitudinal evaluation remains a major limitation to construct optimisation and transl...

Archaeozoology and Biomolecular Analysis in Archaic Phoenician Gadir—The Site of Sagasta–Tinte (9th–8th Centuries BC)

Faunal remains constitute one of the main sources of evidence for reconstructing foodways and economic practices in Phoenician societies. Archaeological research conducted over recent decades in the Iberian Peninsula has highlighted their importance for understanding food product...

p190A / ARHGAP35 and p190B / ARHGAP5 proteins in endometrial cancer: a novel cancer‐relevant paralog interplay

Endometrial cancer is one of the main gynecological malignancies worldwide. Several studies highlight ARHGAP35 as a significantly mutated gene in these tumors. It encodes for p190RhoGAP-A (p190A), which is a major regulator of the small GTPase family of proteins. ARHGAP5 is a par...

Use of cardiac magnetic resonance imaging after hospitalization for acute heart failure: insights from the French nationwide OFICA-2 cohort

Abstract Background Cardiac magnetic resonance (CMR) has a central role in the management of patients with acute heart failure (AHF), but timely access remains heterogeneous. We investigated real-world CMR use in patients hospitalized for AHF and its associations with demographic...

Ancient DNA preservation in the Caribbean

Abstract Ancient DNA (aDNA) analysis has transformed how we study human migration, species dispersals and environmental change, but poor preservation remains a major challenge. This is especially true in tropical settings, where hot and humid conditions accelerate DNA decay. Beca...

Real-space spin-orbit interaction from quarter-wave plate nonuniformity

Abstract Spin–orbit interactions couple light polarization to its transverse structure. Although widely studied at interfaces, in tilted anisotropic plates, and under tight focusing, their role in paraxial confocal systems remains unclear. We show that a commercial quarter-wave p...

Antibacterial Cyclic Oligo(disulfide)s with Tunable Hydrophilicity Dictate Membrane Interactions and Distinct Metabolic Interference

Abstract To combat drug-resistant bacteria, antimicrobial agents with tunable and multi-modal mechanisms are urgently needed. While membrane-disrupting polymers have been widely explored, precisely regulating their membrane interactions and downstream metabolic effects remains ch...

Visual foraging and individual characteristics: Contribution of executive functions and personality

In exhaustive visual foraging tasks, in which observers select multiple instances of two target types, they change their strategy according to the task difficulty. During easy feature-based foraging, observers locate the nearest target and often switch between target types (proxi...

Selective activation of nerve fiber subpopulations with intrafascicular stimulation

Background: Peripheral nerve stimulation (PNS) is most effective when specific nerve fiber subpopulations are activated, while minimizing off-target activation, which may cause undesirable side effects. This selectivity depends primarily on electrode design and charge delivery. W...

The GMRT High-resolution Southern Sky Survey for Pulsars and Transients. VIII. Orbital Variability and the Evolution of a 1 day He-WD Millisecond Pulsar J2101–4802

Abstract We present timing and orbital phase-resolved polarimetry of the millisecond pulsar (MSP) J2101−4802, having a spin period of 9.48 ms and dispersion measure (DM) 25.05 pc cm −3 discovered with the Giant Meter Radio Telescope (GMRT). From the phase-connected timing of this...

Chiral by Nature: Chiroptical Activity in Fe3O4 Magnetic Nanoparticles from Bacterial Biomineralization

Abstract The coexistence of chirality and magnetism in nanomaterials has been observed with metallic complexes but remains rarely achieved in magnetic oxides. Here, we identify biologically induced chiroptical activity in the magnetotactic bacterium Magnetospirillum gryphiswalden...

Coupling between Adsorption, Structure, and Rheology in Short-Side-Chain PFSA Ionomer/Carbon Black Suspensions in N-Propanol/Water

Abstract The rheological behavior of proton exchange membrane fuel cell catalyst inks arises from the coupled structuring of carbon particles and perfluorosulfonic acid (PFSA) ionomer dispersions, both strongly influenced by solvent composition. Here, the microstructure, ionomer...

Rethinking common gardens for forest tree species in the face of climate change

Abstract Key message Maintaining forest resilience under climate change depends on understanding genetic adaptation and preserving diversity. Long-term common garden networks are essential for revealing how species and populations perform across life stages and environments. When...

Astrocytic PI3Kα controls synaptic plasticity and cognitive function via serine metabolism

Astrocytes modulate neuronal activity by gliotransmission and through metabolic regulation, yet the relationship between these functions remains poorly understood. Here we show that phosphatidylinositol 3-kinase (PI3K) signaling in astrocytes controls synaptic plasticity and memo...

Octupole deformation in quasiparticle states of odd-mass and odd-odd nuclei

Abstract As a follow up of [Phys. Scr. 99 055305 (2024)], where we studied axial octupole shapes in two-quasiparticle states of even-even nuclei, we investigate this type of shapes in odd-mass and odd-odd well-deformed nuclei, using the Skyrme-Hartree-Fock-BCS approach with selfc...

Polyproline: A Synthetic Polypeptide With Unique Properties

Polyproline is a unique polypeptide defined by its unusual conformational rigidity and physicochemical behavior. Addressing long-standing challenges in its synthesis and characterization, this mini-review highlights recent advances in the ring-opening polymerization of proline N-...

Accurate MAG reconstruction from a complex soil microbiome through combined short- and HiFi long-reads metagenomics

Abstract Background Advances in high-fidelity long-read (HiFi-LR) sequencing technologies have opened new opportunities to explore the microbial genomic diversity of complex environments, such as soils. While short-read (SR) sequencing has enabled broad insights at the gene level...

Design and analytical validation of Nexthyro 2.0, a custom next-generation sequencing panel integrating DNA mutation profiling and RNA fusion detection for routine thyroid pathology specimens

Abstract The increasing role of molecular testing in thyroid pathology, from the pre-operative stratification of indeterminate fine-needle aspiration (FNA) categories to the management of advanced carcinomas, has prompted the development of institution-specific custom NGS solutio...
