Description of the skull, braincase, and dentition of Moschognathus whaitsi (Dinocephalia, Tapinocephalia), and its palaeobiological and behavioral implications

open access: yesThe Anatomical Record, EarlyView.
Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

Factors affecting the occurrence of maxillary sinus fungus ball

open access: yesFrontiers in Surgery
ObjectiveWe identified patients who initially did not have a maxillary sinus fungus ball on computed tomography (CT) but developed it on a subsequent CT scan. We assessed potential risk factors for developing a maxillary sinus fungus ball between the two

Unique case of inverted papilloma of septum with nasopharyngeal carcinoma:Is it a metachronous tumour? [PDF]

open access: yes, 2020
Inverted papilloma is a rare and benign tumour. It affects the nasal cavity and paranasal sinuses, has a high rate of recurrence and is associated with malignant transformation.

An elastic segment of the whisker shaft enables coding of the whisking phase via whisker torsion in rats and mice

open access: yesThe Anatomical Record, EarlyView.
An elastic segment was found in the basal part of the whisker shaft in rats and mice. Application of force to the whisker bulb of isolated follicles caused bending and twisting of this segment. Active whisker movements deform this segment, causing whisker shaft deflection and selective activation of mechanoreceptors at different phases of whisking ...

Haemangioma of maxillary sinus [PDF]

open access: yesIndian Journal of Otolaryngology and Head & Neck Surgery, 2001
Though haemangioma of nose is a common tumor, those arising from the paranasal sinuses are not very common. Very few cases have been reported. Because of its rarity under the backdrop of existing literature we are reporting our present case.

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

open access: yesThe Anatomical Record, EarlyView.
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 ...

New craniodental materials of Falcarius utahensis (Theropoda: Therizinosauria) reveal patterns of intraspecific variation and cranial evolution in early coelurosaurians

open access: yesThe Anatomical Record, EarlyView.
Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known
