MicroCT reinvestigation of the only articulated fossil anostomid fish reveals synonymy of Arhinolemur Ameghino, 1898 and Megaleporinus Ramirez et al., 2017

open access: yesThe Anatomical Record, EarlyView.
Abstract Arhinolemur scalabrinii† Ameghino, 1898 was originally described as a strepsirrhine primate (Mammalia) but has been recognized as an anostomid fish since 2012. It remains the only extinct anostomid species known from complete cranial material.

Whole-Epiphysis Trabecular Bone in Tamarin Limbs Suggests Effects of Leaping Distance Alongside Non-Biomechanical Factors. [PDF]

open access: yesAm J Biol Anthropol
ABSTRACT Objectives Beyond non‐biomechanical factors, the trabecular architecture of long bone epiphyses variably underlies functional adaptations to locomotor behavior. A recent study, characterizing tamarin trabecular bone using traditional metrics derived from Volumes of Interest (VOIs), identified a preliminary relationship with leaping distance ...

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates

open access: yesThe Anatomical Record, EarlyView.
Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

Slipping of the upper femoral epiphyses in patients with intracranial tumours causing hypopituitarism and chiasmal compression

open access: yes, 1976
Four cases of slipped upper femoral epiphyses in patients with intracranial tumours causing hypopituitarism and chiasmal compression are presented. Detailed endocrine studies in three cases showed severe deficiencies of growth hormone as well as of ...

MR Imaging of Normal Epiphyseal Development and Common Epiphyseal Disorders [PDF]

open access: yesRadioGraphics, 2014
During infancy and childhood, multiple developmental changes occur in the epiphysis. Initially the epiphysis is composed entirely of hyaline cartilage. As skeletal maturation progresses, one or several secondary ossification centers (SOCs) develop within the epiphyseal cartilage.

The fossil record stays silent: Confusions and conundrums for hominin pelvis evolution

open access: yesThe Anatomical Record, EarlyView.
Abstract The evolution of the hominin pelvis is commonly modeled as a series of stages driven largely by the requirements of bipedal locomotion, reproduction, thermoregulation, and pelvic floor muscular support. These patterns are complicated by variation in canal dimensions in relationship with different changes in overall pelvic breadths. To quantify

Developmental differences in cortical bone structure in chimpanzee and human femora reflect early locomotor independence in humans

open access: yesThe Anatomical Record, EarlyView.
Abstract The cortical bone structure of long bone diaphyses changes throughout growth via skeletal modeling and has important implications for bone strength and structural integrity. Ontogenetic trends in diaphyseal structure have been identified in both chimpanzees and humans but it is not yet clear how these trends compare given notable differences ...

Immunolocalization of DMP1 and sclerostin in the epiphyseal trabecule and diaphyseal cortical bone of osteoprotegerin deficient mice [PDF]

open access: yes, 2010
In order to define the osteocytic function in accelerated bone remodeling, we examined the distribution of the osteocytic lacunar-canalicular system (OLCS) and osteocyte-secreting molecules-dentin matrix protein (DMP) 1 and sclerostin-in the epiphyses ...

Improvements in Patient‐Reported Outcomes and Few Reported Major Complications Following Hip Arthroscopy in Patients With Femoroacetabular Impingement Syndrome: A Systematic Review

open access: yesArthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To systematically review the literature to evaluate complications and patient‐reported outcome measures (PROMs) after hip arthroscopy in patients with femoroacetabular impingement syndrome. Methods Five databases were searched for studies reporting complications and PROMs after hip arthroscopy in patients with femoroacetabular impingement ...

The Potential Role of Synovial T Cell Infiltration Following Knee Joint Injury in Symptoms and Progression to Osteoarthritis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Identification of osteoarthritis (OA)–specific synovial inflammatory pathways and their temporal relevance is critical for therapeutic targeting. We compared mononuclear inflammatory/immune cell responses following joint injury that does or does not lead to OA to define bona fide OA‐associated cellular events.
