The Effect of Glucovance Therapy on Biomechanical Deterioration of Bone in Streptozotocin-Induced Diabetic Rats. [PDF]

Acta Endocrinologica, 2019
Is to evaluate the influence of glucovance therapy on biomechanical properties of bone in streptozotocin - induced diabetes mellitus (DM) in rats.A total of 28 male Wistar-Albino rats (12-week-old; 210-300 g) were divided into 4 groups including control (C; no treatment; n=7), sham [Sh; distilled water (gavage, for 8 weeks); n=7], diabetes [DM ...

Progressive Microstructural Deterioration Dictates Evolving Biomechanical Dysfunction in the Marfan Aorta [PDF]

Frontiers in Cardiovascular Medicine, 2021
Medial deterioration leading to thoracic aortic aneurysms arises from multiple causes, chief among them mutations to the gene that encodes fibrillin-1 and leads to Marfan syndrome.

Effects of time-dependent degradation and freezing on biomechanical properties of healthy bovine jejunum

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2023
Degradation of bovine small intestine and respective effects on biomechanics have not been described to date. Biomechanical testing of intestinal tissues is often carried out within a few hours of donor death and tissue deterioration is not accounted for.

Deteriorated biomechanical properties of human hypertrophied septum in response to cardiomyocyte enlargement, overexpressed collagen, and disarrayed microstructures

Frontiers in Bioengineering and Biotechnology
Hypertrophic cardiomyopathy (HCM) is often caused by genetic mutations, resulting in abnormal thickening of ventricular muscle, particularly the septum, and causing left ventricular outflow tract (LVOT) obstruction and inferior cardiac performance.

Deterioration of the fixation segment’s stress distribution and the strength reduction of screw holding position together cause screw loosening in ALSR fixed OLIF patients with poor BMD

Frontiers in Bioengineering and Biotechnology, 2022
The vertebral body’s Hounsfield unit (HU) value can credibly reflect patients’ bone mineral density (BMD). Given that poor bone-screw integration initially triggers screw loosening and regional differences in BMD and strength in the vertebral body exist,

Will the adjustment of insertional pedicle screw positions affect the risk of adjacent segment diseases biomechanically? An in-silico study

Frontiers in Surgery, 2023
BackgroundThe fixation-induced biomechanical deterioration will increase the risk of adjacent segment diseases (ASD) after lumbar interbody fusion with Bilateral pedicle screw (BPS) fixation. The accurate adjustment of insertional pedicle screw positions

TELD with limited foraminoplasty has potential biomechanical advantages over TELD with large annuloplasty: an in-silico study

BMC Musculoskeletal Disorders, 2021
Background Facetectomy, an important procedure in the in–out and out–in techniques of transforaminal endoscopic lumbar discectomy (TELD), is related to the deterioration of the postoperative biomechanical environment and poor prognosis.

The Mismatch Between Bony Endplates and Grafted Bone Increases Screw Loosening Risk for OLIF Patients With ALSR Fixation Biomechanically

Frontiers in Bioengineering and Biotechnology, 2022
The mismatch between bony endplates (BEPs) and grafted bone (GB) triggers several complications biomechanically. However, no published study has identified whether this factor increases the risk of screw loosening by deteriorating the local stress levels.
