Confined compression of collagen hydrogels [PDF]

, 2013
Reconstituted collagen hydrogels are often used for in vitro studies of cell-matrix interaction and as scaffolds for tissue engineering. Understanding the mechanical and transport behaviours of collagen hydrogels is therefore extremely important, albeit ...

Biomimetic Glycosaminoglycan‐Analog Hydrogel for Improved Embolization of Aneurysms: Environment‐Selective Swelling

Advanced Healthcare Materials, EarlyView.
Biomimetic glycosaminoglycan analog hydrogels exhibit suitable and robust mechanical properties, as well as hemocompatibility and biocompatibility, making them ideal for the embolization of intracranial aneurysms. Notably, the hydrogel's environment‐selective swelling properties enable complete blockage of the aneurysm cavity while preventing ...

Dynamic behavior of the nucleus pulposus within the intervertebral disc loading: a systematic review and meta-analysis exploring the concept of dynamic disc model

Frontiers in Bioengineering and Biotechnology
IntroductionThe dynamic disc model (DDM) is a theoretical framework in spine mechanics that theorizes the behavior of the nucleus pulposus within the intervertebral disc under various loads.

Not all lumbar herniated discs cause low back pain

Horizonte Médico, 2017
After a long series of terms used to define the displacement of disc material (either the nucleus pulposus or the fibrous ring), herniated discs were classified as bulging, focal protrusion, extrusion and sequestration. Herniated discs represent from 1%

Biomechanical comparison between unilateral and bilateral percutaneous vertebroplasty for osteoporotic vertebral compression fractures: A finite element analysis

Frontiers in Bioengineering and Biotechnology, 2022
Background and objective: The osteoporotic vertebral compression fracture (OVCF) has an incidence of 7.8/1000 person-years at 55–65 years. At 75 years or older, the incidence increases to 19.6/1000 person-years in females and 5.2–9.3/1000 person-years in

Spine intervertebral disc labeling using a fully convolutional redundant counting model [PDF]

arXiv, 2020
Labeling intervertebral discs is relevant as it notably enables clinicians to understand the relationship between a patient's symptoms (pain, paralysis) and the exact level of spinal cord injury. However manually labeling those discs is a tedious and user-biased task which would benefit from automated methods. While some automated methods already exist

Implementing BMP‐7 Chemically Modified RNA for Bone Regeneration with 3D Printable Hyaluronic Acid‐Collagen Granular Gels

Advanced Healthcare Materials, EarlyView.
This study developed 3D‐printable THA‐Col microgels for delivering BMP‐7 cmRNA. The key result is that hMSCs transfected on the biomaterials showed BMP‐7 secretion levels comparable to pre‐transfected hMSCs, therefore introducing a cmRNA‐activated matrix to promote bone healing.
