Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs

The Anatomical Record, EarlyView.
Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.

Preperihelion Development of Interstellar Comet 3I/ATLAS

The Astrophysical Journal Letters
We describe preperihelion optical observations of interstellar comet 3I/ATLAS taken during 2025 July–September using the Nordic Optical Telescope. Fixed aperture photometry of the comet is well described by a power-law function of heliocentric distance ...

Unveiling the Microvasculature: The Index of Microcirculatory Resistance and Its Expanding Role in Cardiovascular Care

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Index of microcirculatory resistance (IMR) is a cutting‐edge, wire‐based tool that advances the capability assessment of coronary microvascular function. By utilizing distal coronary pressure and mean transit time under maximal hyperemia, IMR delivers consistent, reproducible insights into the microvasculature's dynamic health.

Watching a Comet Turn On: High Spectral Resolving Power Observations of Comet C/2017 K2 (PanSTARRS)

The Planetary Science Journal
We report high spectral resolving power optical observations of comet C/2017 K2 (PanSTARRS) as it approached the Sun. This comet was discovered when it was 16 au from the Sun. At discovery, the comet had a large and relatively bright coma.

Impact of Methylparaben on Cumulus Cell DNA Integrity and Porcine Oocyte Developmental Competence In Vitro

Journal of Applied Toxicology, EarlyView.
ABSTRACT Parabens (PBs) are compounds widely used as preservatives in personal care products, food, and pharmaceuticals. Methylparaben (MePB) is the most used by different industries due to its chemical properties and low cost. The high daily human exposure to these compounds has raised concerns about their potential effects on health, particularly on ...

TNO or Comet? The Search for Activity and Characterization of Distant Object 418993 (2009 MS9)

The Planetary Science Journal, 2023
The perihelion of the trans-Neptunian object (TNO) 2009 MS9 brings it close to the distance where some long-period comets are seen to become active.

Beyond Tradition: An Integrated Toxicological, Ecological, and Public Health Perspective on Aristolochic Acids

Journal of Applied Toxicology, EarlyView.
ABSTRACT Aristolochia species have long been used in traditional medicine for their presumed anti‐inflammatory, analgesic and antimicrobial properties. However, extensive toxicological and epidemiological evidence now demonstrates that these plants contain aristolochic acids (AAs) I and II, highly potent nephrotoxic, genotoxic, and carcinogenic ...

Nail Disorders in Systemic Conditions

JEADV Clinical Practice, EarlyView.
ABSTRACT Nail findings in children can be indicative of an underlying systemic disease. Many of these findings are seen in multiple entities and are not specific to one disease. The importance of specifically examining for these nail changes cannot be overstated.
