Estimation and rapid identification of later stages during embryonic development of the oviparous lizard Sceloporus aeneus (Squamata: Phrynosomatidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract Stages of embryonic development for reptiles have been presented in tables that may include all or part of embryonic development. When oviposition occurs in some lizards, embryos are already in the later stages of development; likewise, the size of the eggs increases as incubation time progresses.

Reliable Landmarks for Common Femoral Artery Cannulation: Femoral Head or Inguinal Skin Crease?

open access: yesIndian Journal of Vascular and Endovascular Surgery
Context: Angiography catheterization through the femoral artery (FA) carries risks of vascular complications. The optimal site for puncture is above the common FA bifurcation (CFAB) and below the inferior epigastric artery.

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.

Traumatic anterior dislocation of the hip associated with ipsilateral femoral neck fracture: a case report

open access: yesActa Orthopaedica et Traumatologica Turcica, 2020
A thirty-nine-year-old female patient was brought to the emergency room following an automobile accident. Radiographic examination revealed a subcapital fracture of the left femur associated with anterior femoral head dislocation, and a contralateral ...

Risk factors for ischemic osteonecrosis of the femoral head after internal fixation with multiple cannulated screws for Pauwels type III femoral neck fracture [PDF]

open access: yesVojnosanitetski Pregled
Background/Aim. Numerous factors lead to hip fractures that are common and often devastating in the geriatric population. The aim of the study was to determine the risk factors for ischemic osteonecrosis of the femoral head (ONFH) in patients after ...

Incongruent phylogenetic hypotheses and character conflicts in morphology : the root and early branches of the hexapodan tree [PDF]

open access: yes, 2008
Before the turn of the millenium the investigation of phylogenetic relationships was revolutionized by two major inputs, the use of molecular sequence data for phylogenetic reconstruction, paralleled by the sophistication of computer aided reconstruction

Trabecular bone ontogeny of the human talus

open access: yesThe Anatomical Record, EarlyView.
Abstract Studies of trabecular ontogeny may provide insight into the factors that drive healthy bone development. There is a growing understanding of how the juvenile skeleton responds to these influences; however, gaps in our knowledge remain. This study aims to identify ontogenetic trabecular patterns and regional changes during development within ...

Broadening the semiaquatic scene: Quantification of long bone microanatomy across pinnipeds

open access: yesThe Anatomical Record, EarlyView.
Abstract Investigations of bone microanatomy are commonly used to explore lifestyle strategies in vertebrates. While distinct microanatomical limb bone features have been established for exclusively aquatic and terrestrial lifestyles, identifying clear patterns for the semiaquatic lifestyle remains more challenging.

The tiger salamander as a promising alternative model organism to the axolotl for fracture healing and regenerative biology research

open access: yesThe Anatomical Record, EarlyView.
Abstract Scientists have been captivated by the ability to regenerate, focusing on uncovering the mechanisms of epimorphic regeneration and applying them to human medicine. The axolotl (Ambystoma mexicanum) has become the most intensively studied model in tetrapod regeneration research, particularly concerning limb regeneration.
