MicroCT reinvestigation of the only articulated fossil anostomid fish reveals synonymy of Arhinolemur Ameghino, 1898 and Megaleporinus Ramirez et al., 2017

The Anatomical Record, EarlyView.
Abstract Arhinolemur scalabrinii† Ameghino, 1898 was originally described as a strepsirrhine primate (Mammalia) but has been recognized as an anostomid fish since 2012. It remains the only extinct anostomid species known from complete cranial material.

Oldest well‐preserved euprimate petrosal, from the early Eocene of India (Vastan Lignite Mine, Gujarat)

The Anatomical Record, EarlyView.
Abstract An exquisitely preserved, isolated partial petrosal with associated fragmentary stapes is described from the Vastan Lignite Mine (Gujarat, India), dated to the early Eocene (~54.5 Ma). Several anatomical traits (e.g., large petrosal plate; posterolateral entry of the internal carotid artery to the tympanic cavity; bony tubes surrounding the ...

The E3 Ubiquitin Ligase UBE3B Regulates Synaptic Development and Cortical Network Activity

Autism Research, EarlyView.
ABSTRACT Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by impaired communication, abnormal social interactions, and restricted, repetitive behaviors. Pathogenic mutations in UBE3B result in neurodevelopmental disease, including intellectual disability, lack of speech, and ASD.

Effect of carbamazepine on the pharmacokinetics of vepdegestrant, a PROteolysis TArgeting Chimera estrogen receptor degrader, in healthy adults

British Journal of Clinical Pharmacology, EarlyView.
Aim To evaluate the effects of carbamazepine, a strong cytochrome P450 (CYP)3A4 inducer, on the pharmacokinetics and safety of vepdegestrant, a PROteolysis TArgeting Chimera estrogen receptor degrader. Methods This was a phase 1, open‐label, fixed‐sequence, two‐period study in healthy adult participants.

Mapping opioid exposure through prescription data and postmortem analysis of opioid drugs in multiple tissues

British Journal of Clinical Pharmacology, EarlyView.
Background and Purpose Although opioids are central to end of life (EoL) care, tissue‐level opioid exposure remains poorly understood. The objective of this study was to characterize the relationship between prescription‐derived morphine equivalent daily dose (MEDD) and measured morphine concentrations across multiple organs.
