MicroCT esamination of human bone specimens: effects of polymethylmethacrylate embedding on structural parameters

, 2007
X-ray microtomography permits the nondestructive investigation of trabecular and cortical bone specimens without special preparation of the sample. To do a quantitative characterization, the cross-section images have to be binarized, separating bone from

Effects of intermittent exposure to hypobaria and cold on the microarchitecture and morphofunctional profile of rat gastrocnemius muscle

The Anatomical Record, Volume 309, Issue 11, Page 3330-3344, November 2026.
Abstract Intermittent hypobaric hypoxia (IHH) enhances oxygen transport, muscle metabolism, and cardiovascular health; however, the combined effects of hypobaria and cold are less well understood. Exposure to these stressful environmental factors, even intermittently, can affect skeletal muscle due to its plasticity, thereby altering its metabolic and ...

Investigation of Systematic Discrepancies Between MCC and TGA Measurements Affecting the Determination of Heat of Combustion

Fire and Materials, Volume 50, Issue 7, Page 771-787, November 2026.
ABSTRACT The determination of step‐resolved effective heats of combustion is essential for detailed pyrolysis modelling in fire growth and flame spread predictions, especially in multi‐step processes where the heat of combustion can differ between reaction steps.

Cranioplasty using castor oil–based polyurethane in a dog with Grade II multilobular osteochondrosarcoma

Veterinary Record Case Reports, Volume 14, Issue 4, November 2026.
Abstract Multilobular osteochondrosarcoma is an uncommon tumour that affects the flat bones of the skull. Surgical removal of these lesions often results in large osseous defects that require reconstruction using conventional materials or metallic implants.

Assessing the microstructure of simple rhamphothecae in chickens (Aves: Galliformes: Gallus gallus domesticus)

Journal of Anatomy, Volume 249, Issue 5, Page 1099-1111, November 2026.
Simple rhamphotheca are externally homogeneous but internally are composed of several corneous layers with varying hardness. Areas under more mechanical stress such as the rostral portion and the tomia are significantly harder than other areas. Abstract Corneous sheaths on the jaws of beaked tetrapods, or rhamphothecae, are classified as simple or ...

Correlation of size specific dose estimates with organ dose in abdominal spectral computed tomography

Journal of Applied Clinical Medical Physics, Volume 27, Issue 10, October 2026.
Abstract Background In abdominal spectral Computed Tomography (CT), organ dose assessment is important for radiation safety but remains challenging due to the complexity of Monte Carlo (MC) simulations. Purpose This study aimed to compare the correlations of three size‐specific dose estimate (SSDE) metrics (including the central slice SSDEcenter, the ...

The Intraoperative Fabrication of PMMA Patient-Specific Enophthalmos Wedges and Onlays for Post-Traumatic OZC Reconstruction

Craniomaxillofacial Trauma & Reconstruction
Objective: Trauma is a leading cause of enophthalmos, typically resulting from an increase in the volume of the bony orbit. The general consensus is that post-traumatic primary deformity repair should aim to restore the premorbid volume, shape, and ...
