Evolutionary morphology of the haplorhine hamate

The Anatomical Record, EarlyView.
Abstract Primates adopt a variety of hand postures during an impressive diversity of locomotor and manipulative behaviors. Morphological research has found that elements of the hand skeleton, such as the hamate, hold key information for inferring hand use and locomotor kinematics in extinct species.

Serum bile acids as a prognostic biomarker in biliary atresia following Kasai portoenterostomy

Hepatology, EarlyView., 2022
Serum bile acid levels predict outcomes in patients with biliary atresia who achieve normalized bilirubin levels after Kasai portoenterostomy. Abstract Background and Aims In biliary atresia, serum bilirubin is commonly used to predict outcomes after Kasai portoenterostomy (KP).

Autoreactivity Versus Autoimmunity: Characteristics of Autoantigen‐Specific CD4 T Cells in Rheumatoid Arthritis and Health

Arthritis &Rheumatology, EarlyView.
Objective CD4 T cells specific for citrullinated (cit) peptides are key players in rheumatoid arthritis (RA) immunopathogenesis. Characterizing these cells and identifying features of healthy and RA‐associated autoreactivity will provide valuable insight into disease mechanisms and form the basis of immune state biomarkers to facilitate the next ...

Equatorward expansion of the auroral oval during the May 2024 geomagnetic storm observed over Europe by FRIPON all-sky cameras and satellites

Journal of Space Weather and Space Climate
Context: The geomagnetic storm of 10–11 May 2024, also known as the Mother’s Day storm or Gannon storm, was among the most intense geomagnetic storms in recent decades.

Increased Plasma Microbial tDR‐1 in At‐Risk Individuals Is Associated With Decreased Conversion to Clinical Rheumatoid Arthritis and Reduces an In Vitro Macrophage Type 1 Interferon Response

Arthritis &Rheumatology, EarlyView.
Objective Microbial small RNAs can regulate human genes. Higher plasma concentrations of microbial transfer RNA (tRNA)‐derived RNA‐1 (tDR‐1) were previously associated with lower rheumatoid arthritis (RA) disease activity. This study examined whether tDR‐1 concentrations differ in anticyclic citrullinated peptide‐3 positive (CCP3+) at‐risk individuals (

Some early descriptions of aurorae in China

Annales Geophysicae
Eight accounts from ancient Chinese literature have been found that describe phenomena in contexts and in metaphors that are distinctly auroral. These accounts relate to personages purported to have lived in the third millennium B.C.

Dnmt3a Mutations Limit Normal and Autoreactive CD4+ T Follicular Helper Responses and Attenuate T Cell–Driven Joint Inflammation

Arthritis &Rheumatology, EarlyView.
Objective Somatic DNMT3A mutations are the most common drivers of clonal hematopoiesis in patients with rheumatoid arthritis (RA) and have been associated with seropositive disease and increased markers of inflammation. These mutations are predominantly hypomorphic or dominant‐negative, reducing DNMT3A function.

Impact of Electron Precipitation on Brown Dwarf Atmospheres and the Missing Auroral Emission

The Astrophysical Journal
Recent observations have demonstrated that very low-mass stars and brown dwarfs are capable of sustaining strong magnetic fields despite their cool and neutral atmospheres.

Deep Immunophenotyping Reveals Distinct Immune Signatures in Axial Spondyloarthritis and Psoriatic Arthritis

Arthritis &Rheumatology, EarlyView.
Objective Axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA) are overlapping yet distinct conditions within the SpA spectrum. As divergent immunophenotypes may influence disease course and therapeutic response, we compared immune cell subsets, cytokine profiles, and inflammatory mediators.
