Osteohistology of two phorusrhacids reveals uninterrupted growth strategy

open access: yesThe Anatomical Record, EarlyView.
Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

Evolution of the eyes of vipers with and without infrared-sensing pit organs [PDF]

open access: yes, 2019
We examined lens and brille transmittance, photoreceptors, visual pigments, and visual opsin gene sequences of viperid snakes with and without infrared-sensing pit organs. Ocular media transmittance is high in both groups.

Paleopathology of a putative colossosaurian caudal vertebra (Neosauropoda: Titanosauria) from the Presidente Prudente Formation, Brazil

open access: yesThe Anatomical Record, EarlyView.
Abstract Studies investigating paleopathologies in sauropods remain scarce despite their relative abundance in the fossil record. In this study we report new occurrence of paleopathological features, corresponding to a neoplasm found in a middle caudal vertebra (MCT.R.2120) of an advanced titanosaur from the Presidente Prudente Formation (Bauru Basin ...

Dendritic Cell Neurofibroma with Pseudorosette: An Uncharted Entity at Unusual Sites: Two Case Reports with Literature Review

open access: yesJournal of Dermatology and Dermatologic Surgery
Dendritic cell neurofibroma with pseudorosette (DCNP) is a novel entity of neurofibroma with sparse literature. Neurofibroma is a benign peripheral nerve sheath tumor having many known histological variants including localized, diffuse, plexiform ...

Cyclic GMP in the pig vitreous and retina after experimental retinal detachment [PDF]

open access: yes, 2008
Purpose: Earlier studies have revealed a decreased level of cGMP in vitreous fluid obtained from patients with a retinal detachment. To further investigate this phenomenon, we developed an experimental retinal detachment model in pigs.

General features of the retinal connectome determine the computation of motion anticipation [PDF]

open access: yes, 2015
Motion anticipation allows the visual system to compensate for the slow speed of phototransduction so that a moving object can be accurately located.

Autonomic Plexuses of the Female Sexual Organs Travel Within Pubocervical and Rectovaginal [Endopelvic] Fascia: A Rationale for ‘Nerve‐Aware’ Vaginal Prolapse Repair

open access: yesClinical Anatomy, EarlyView.
ABSTRACT The connective tissue support of female pelvic viscera—endopelvic fascia—has been studied in fetal and immunohistochemical models to demonstrate its relationship with the autonomic nerves of the female pelvis. Due to a paucity of literature examining the gross anatomical relationships between endopelvic fascia and autonomic nerves in adult ...

Plexiform’s perplexities: a tale of two plexiform neurofibromas

open access: yesJournal of Surgical Case Reports
Abstract Plexiform neurofibroma (PF) is a rare benign variant belonging to a subtype of neurofibromatosis type 1 that forms bulging or deforming masses arising from the peripheral nerve sheath. These masses involve surrounding connective tissue or dermal layers, leading to multiple cutaneous changes and certain characteristic appearances.

Development of a Zebrafish Embryo‐Based Test System for Thyroid Hormone System Disruption: 3Rs in Ecotoxicological Research

open access: yesEnvironmental Toxicology and Chemistry, EarlyView.
Abstract There is increasing concern regarding pollutants disrupting the vertebrate thyroid hormone (TH) system, which is crucial for development. Thus, identification of TH system–disrupting chemicals (THSDCs) is an important requirement in the Organisation for Economic Co‐operation and Development (OECD) testing framework.
