The skeleton of the green Iguana iguana (Squamata: Iguanidae) and its intraspecific morphological variation

open access: yesThe Anatomical Record, EarlyView.
Abstract The green iguana (Iguana iguana) is an iguanine lizard with herbivorous and arboreal habits, whose distribution spans through South America, Central America to the south of North America. Although the genus Iguana is well‐known, the species still lacks a comprehensive and up‐to‐date anatomical study, particularly addressing the axial skeleton,

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

open access: yesThe Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Finite element model creation and stability considerations of complex biological articulation : the human wrist joint [PDF]

open access: yes, 2010
The finite element method has been used with considerable success to simulate the behaviour of various joints such as the hip, knee and shoulder. It has had less impact on more complicated joints such as the wrist and the ankle.

Evaluation of the pelvic apophysis with multi-detector computed tomography for legal age estimation in living individuals

open access: yesJournal of Research in Medical Sciences, 2015
Background: Legal age estimations of living individuals are gaining increasing importance for radiologists involved in delivering expert opinions. The present study aimed to assess the correlation between chronological age and apophyseal centers distance

Over the edge: Empirical evidence for the cliff‐edge model of obstetric selection

open access: yesThe Anatomical Record, EarlyView.
Abstract The cliff‐edge model of obstetric selection maintains that larger neonates and smaller birth canals confer a positive selective advantage until labor becomes obstructed and vaginal delivery is no longer possible, eliciting an abrupt reduction in fitness.

A new composite flap model in the rat - Combined cremaster muscle and pubic bone flap

open access: yes, 2008
Background: We introduce a new model of combined cremaster muscle and pubic bone flap based on a single pedicle consisting of the osseous branch of pubic bone and external spermatic vessels of cremaster muscle in continuity with the pudic-epigastric ...

The Complex Challenge of Urosymphyseal Fistula and Pubic Osteomyelitis in Prostate Cancer Survivors

open access: yesEuropean Urology Open Science
Background and objective: Urosymphyseal fistula (UF) and pubic osteomyelitis (PO) are rare and often poorly recognized long-term complications of treatment for localized prostate cancer. Our aim was to describe UF/PO in prostate cancer survivors. Methods:

Treatment of a sacral fracture associated with an intrasacral meningocele: A case report

open access: yesJournal of Orthopaedic Surgery, 2019
We report a case of sacral fracture complicated by an intrasacral meningocele in a 37-year-old male. The patient had a left sacral fracture with bilateral fractures of the superior and inferior pubic rami.

Is miniscrew primary stability influenced by bone density?

open access: yesBrazilian Oral Research, 2011
Primary stability is absence of mobility in the bone bed after mini-implant placement and depends on bone quality among other factors. Bone quality is a subjective term frequently considered as bone density.

A second species of non‐crocodyliform crocodylomorph from the Late Triassic fissure deposits of southwestern UK: Implications for locomotory ecological diversity in Saltoposuchidae

open access: yesThe Anatomical Record, EarlyView.
Abstract The Late Triassic–Early Jurassic fissures of the Bristol Channel area (southwest England and south Wales) are renowned for their diverse vertebrate faunas. These assemblages have yielded an array of predominantly small‐bodied forms that are crucial to our understanding of the early evolution of several major tetrapod clades.
