The medullary respiratory neurons: a review
The medullary respiratory neurons involved in the generation of respiratory rhythm are reviewed. The subject is introduced by a brief description of the history of respiratory neurophysiology and of the pontine respiratory neurons.

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy
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.

Metachronous Follicular Variant of Papillary Thyroid Microcarcinoma in a Case of Medullary Carcinoma Thyroid [PDF]
Medullary carcinoma and papillary thyroid carcinoma arise from the different cells. Simultaneous occurrence of both types is rare. Medullary carcinomas are characterised by calcitonin positivity.

This review redefines the carotid bulb (CB) as a variable geometric dilation shaped by hemodynamics and the carotid sinus (CS) as a conserved neurohistological baroreceptor field. Distinguishing these entities clarifies a century of anatomical confusion and links geometry, neurohistology, and clinical interpretation within a unified framework ...

Abstract Neuroanatomical research has progressed considerably in several vertebrate lineages, yet studies of reptilian brain morphology remain markedly underdeveloped. Here we provide the first description of macroscopic brain anatomy and its ontogeny in the viperid Bothrops moojeni, based on a sample of seven individuals.

Abstract The preauricular sulcus has long been debated as a pelvic feature variably attributed to obstetric stress, ligamentous traction, and broader biomechanical processes. To clarify its determinants, we analyzed 409 adult individuals from three archeological and one early modern skeletal collection from the Iberian Peninsula, integrating graded ...

The largest silesaurid known from South America is described here, demonstrating that silesaurids reached large body sizes in southwestern Gondwana. This discovery further underscores the widespread geographic distribution and temporal persistence of large silesaurids across Pangea, despite faunal turnovers and environmental events such as the Carnian ...

Abstract Primates show a high degree of locomotor diversity that engenders similar variance in limb bone cross‐sectional geometry and bending strength: leaping primates have stronger hindlimb bones whereas suspensory species have stronger forelimb bones.

Role of Twist1 transcription factor in thyroid tumor progression
Thyroid carcinomas are the most common endocrine tumors in humans, with a globally increasing incidence. Differentiated tumors, such as papillary (PTC) and follicular (FTC) thyroid cancers, are often curable with surgical resection and radiotherapy ...

Abstract Prozostrodon brasiliensis, a probainognathian cynodont of the clade Prozostrodontia, is recognized as a key taxon for understanding the origin of Mammaliaformes and mammals. Despite detailed investigations of its cranial anatomy, the postcranial skeleton has received comparatively less attention.
