Computed tomography reveals the endocranial anatomy of Crocodylia: Implications for phylogenetic relationships and ecomorphological convergence across Crocodylomorpha

open access: yesJournal of Anatomy, Volume 249, Issue 6, Page 1368-1427, December 2026.
The evaluation of the endocranial anatomy of 43 crocodylian species reveals several differences, including variation in the curvature of the encephalic endocast, the size of the endosseous labyrinth and paratympanic sinuses, and the presence of additional snout sinuses.

Dynamic Proton arc therapy for paediatric parameningeal rhabdomyosarcoma

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 11, November 2026.
Abstract Background Parameningeal rhabdomyosarcomas (PM‐RMS) are pediatric tumors with a high risk of local failure and severe toxicity. Intensity modulated proton therapy (IMPT) offers improved healthy tissue sparing compared to conventional photon‐based radiotherapy, and proton arc therapy (PAT) might offer further improvement in healthy tissue ...

Bilateral lacrimal system involvement by sclerosing extramedullary hematopoietic tumor

open access: yes, 2019
A 60-year-old man with myelofibrosis and extramedullary hematopoiesis was referred for evaluation of “swollen lacrimal glands.” Examination disclosed bilateral firm, immobile, nontender masses in the lacrimal sac fossa with no associated signs of ...

A bristle‐nosed Jurassic ray‐finned fish (Actinopterygii) bears true dermal odontodes on its snout

open access: yesJournal of Anatomy, Volume 249, Issue 5, Page 1021-1032, November 2026.
Teeth show extreme diversity, including tooth‐like dermal odontodes or “skin teeth” in many extant fishes. We describe the anatomy of enlarged tubercles on the snout of Redfieldius, an extinct early Jurassic fish. We found that the tubercles in Redfieldius are dermal odontodes that evolved independently from those of living species. Abstract Comparison

Bilaterally Diffuse Lacrimal Gland Involvement: Initial Presentation of Systemic Sarcoidosis [PDF]

open access: yes, 2017
Orbital involvement in systemic sarcoidosis is a rare condition. We report a case of orbital sarcoidosis with bilaterally huge lacrimal gland involvement as the initial manifestation of systemic sarcoidosis. A 20-year-old woman admitted the ophthalmology

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

open access: yesThe Anatomical Record, Volume 309, Issue 10, Page 2656-2697, October 2026.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...
