Imaging findings for Atlanto-occipital assimilation with multiple cervical vertebral anomalies in a Beagle dog: A 2 year follow-up

Veterinární Medicína, 2020
A 3-year-old male Beagle dog was presented for a physical examination, which revealed a mild stiff neck that was affecting movement. The imaging modalities led to our diagnosis of an asymmetric fusion of the occipital condyle and atlas wing consistent ...

Unravelling intravertebral integration, modularity and disparity in Felidae (Mammalia) [PDF]

, 2017
Morphological integration and modularity, which describe the relationships among morphological attributes and reflect genetic, developmental, and functional interactions, have been hypothesized to be major influences on trait responses to selection and ...

The coelurosaur theropods of the Romualdo formation, early Cretaceous (Aptian) of Brazil: Santanaraptor placidus meets Mirischia asymmetrica

The Anatomical Record, EarlyView.
Abstract The upper carbonate concretion levels of the Romualdo Formation (Aptian, Brazil) have yielded several theropod dinosaur remains, including spinosaurids and the coelurosaurs Santanaraptor placidus and Mirischia asymmetrica, the phylogenetic affinities of which are controversial.

Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)

The Anatomical Record, EarlyView.
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

Suboccipital lateral injection of intrathecal chemotherapy in a patient with mantle cell lymphoma [PDF]

, 2004
Background: Even today patients who suffer from mantle cell lymphoma have a poor prognosis, especially when the CNS is involved. To confirm the diagnosis of meningeosis lymphomatosa, asservation of the liquor cerebrospinalis is necessary.

Unfused transverse foramen of the atlas vertebra in the Neandertal lineage fossils

The Anatomical Record, EarlyView.
Abstract In anatomically modern humans, the atlas can display an unfused transverse foramen (UTF) but currently the presence of UTF in the Neandertal lineage is uncertain due to a scarcity of prevalence studies and no exhaustive record of its presence throughout the entire hominin fossil record.

Safety and Efficacy of 10 kHz Spinal Cord Stimulation for the Treatment of Refractory Chronic Migraine: A Prospective Long‐Term Open‐Label Study

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Background Refractory chronic migraine (rCM) is a highly disabling condition for which novel safe and effective treatments are needed. Safety and long‐term efficacy of paresthesia‐free high cervical 10 kHz spinal cord stimulation (SCS) were here prospectively evaluated for the treatment of rCM.

Histological evidence for a supraspinous ligament in sauropod dinosaurs [PDF]

, 2015
Supraspinous ossified rods have been reported in the sacra of some derived sauropod dinosaurs. Although different hypotheses have been proposed to explain the origin ofthis structure, histological evidence has never been provided to support or reject any

Re‐evaluation of a soft crested Edmontosaurin, with implications for hadrosaurid life appearance and diversity

The Anatomical Record, EarlyView.
Abstract Hadrosaurid dinosaurs are generally regarded as “crested” or “non‐crested” depending on the presence or absence of a bony cranial crest. At least one supposedly “non‐crested” hadrosaur is known to have possessed a soft tissue cranial crest (or comb), based on an exceptionally preserved “mummified” specimen. Here we redescribe this specimen and
