Inside a duck‐billed dinosaur: Vertebral bone microstructure of Huallasaurus (Hadrosauridae), Upper Cretaceous of Patagonia

open access: yesThe Anatomical Record, EarlyView.
Abstract Dinosaurs evolved a unique respiratory system with air sacs that contributed to their evolutionary success. Postcranial skeletal pneumaticity (PSP) has been used to infer the presence of air sac systems in some fossil archosaurs. While unambiguous evidence of PSP is well documented in pterosaurs and post‐Carnian saurischians, it remains absent

Non-alcoholic fatty liver disease connections with fat-free tissues: A focus on bone and skeletal muscle [PDF]

open access: yes, 2017
The estimates of global incidence and prevalence of non-alcoholic fatty liver disease (NAFLD) are worrisome, due to the parallel burden of obesity and its metabolic complications. Indeed, excess adiposity and insulin resistance represent two of the major

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

open access: yesThe 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.

Patterns of spinal motion, kinematic spaces and the land‐to‐sea transition in carnivorans

open access: yesThe Anatomical Record, EarlyView.
Using 3D reconstructions, we quantify intervertebral joint mobility to investigate how cervical, thoracic, and lumbar vertebral regions evolved distinct kinematic roles in pinnipeds. The findings reveal lineage‐specific adaptations for swimming and highlight the functional significance of vertebral joint flexibility in ecological transitions.

Drivers of tail evolution in squamates and their implications for the fossorial origin of snakes

open access: yesThe Anatomical Record, EarlyView.
Abstract The axial skeleton serves as the primary structural support in all vertebrates and is subdivided into five distinct regions: cervical, thoracic, lumbar, sacral, and caudal. Relaxation of constraints acting on the terminal end of the axial skeleton has led to remarkable variation in caudal vertebrae number across Squamata.

Concomitant Lumbar Spine Pathology in Patients Undergoing Hip Arthroscopy: A Matched Cohort Analysis

open access: yesOrthopaedic Journal of Sports Medicine, 2017
Objectives: Hip arthroscopy for femoroacetabular impingement (FAI) and related hip pathology is increasing in volume. Variable presentations of hip pain often lead to confusion with lumbar spine pathology however.

Biologic and Targeted Synthetic Disease‐Modifying Antirheumatic Drugs Do Not Arrest Bone Loss in Patients With Rheumatoid Arthritis: A Long‐Term Multicenter Observational Study

open access: yesArthritis &Rheumatology, EarlyView.
Objective Osteoporosis causes fractures that further increase the disease burden of rheumatoid arthritis (RA); however, osteoporosis treatment rates remain low. Although several studies have reported that biologic or targeted synthetic disease‐modifying antirheumatic drugs (b/tsDMARDs) can prevent or improve osteoporosis in RA, our large‐scale, real ...
