Degradation, water uptake, injectability and mechanical strength of injectable bone substitutes composed of silk fibroin and hydroxyapatite nanorods

Revista Facultad de Ingeniería, 2018
Injectable bone substitutes are generally composite materials capable of being extruded through a device; they consist of a solid phase inside a matrix that allows the easy movement of particles. Injectable bone substitutes have the advantage of allowing

Bone grafts and bone substitutes in dentistry

Journal of Oral Research and Review, 2016
Bone resorption is a natural phenomenon and can occur due to old age, loss of teeth, prolonged denture wear, or as a result of systemic conditions. For the replacement of teeth by fabrication of prosthesis or the use of implants, a minimum amount of bone

Mechanistic Illustration: How Newly-Formed Blood Vessels Stopped by the Mineral Blocks of Bone Substitutes Can Be Avoided by Using Innovative Combined Therapeutics

Biomedicines, 2021
One major limitation for the vascularization of bone substitutes used for filling is the presence of mineral blocks. The newly-formed blood vessels are stopped or have to circumvent the mineral blocks, resulting in inefficient delivery of oxygen and ...

Osteoconductive Microarchitecture of Bone Substitutes for Bone Regeneration Revisited

Frontiers in Physiology, 2018
In the last three decades, all efforts in bone tissue engineering were driven by the dogma that the ideal pore size in bone substitutes lies between 0.3 and 0.5 mm in diameter.

Spinal fusions: bone and bone substitutes [PDF]

European Spine Journal, 2000
Vertebral arthrodesis is one of the most commonly performed, yet incompletely understood, procedures in spinal surgery. Despite major progress in internal fixation techniques, the high rate of nonunions indicates that physiologic, biologic and molecular events that are crucial to this process are not well known.

Clinical and Biological Features of Response in Resistant Neuroblastoma to 131I‐Metaiodobenzylguanidine Radiotherapy in the Anti‐GD2 Immunotherapy Era

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background 131I‐metaiodobenzylguanidine (131I‐MIBG) radiotherapy is a key treatment for relapsed and refractory (R/R) neuroblastoma (NB). Patients with R/R disease treated in the modern era are increasingly exposed to anti‐GD2 immunotherapy, which exerts selective pressure and may modify both tumor cell state and microenvironment.

Comparison of efficacies of different bone substitutes adhered to osteoblasts with and without extracellular matrix proteins

Journal of Dental Sciences, 2013
Background/purpose: Regeneration of bony tissue is a major goal in periodontal and implant surgery. The adhesion efficacy of osteogenic cells to bone substitutes is a determinant for osteogenesis.

Deep Sequencing of FLT3‐ITD Enables Response Evaluation and Post‐Treatment Monitoring in Childhood AML: An Exploratory Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background An internal tandem duplication in the gene encoding Fms‐like tyrosine kinase 3 (FLT3‐ITD) is associated with high relapse risk and poor prognosis in acute myeloid leukemia (AML) and plays a crucial role in treatment decisions. Measurable residual disease (MRD) analysis of FLT3‐ITD during and after treatment has shown prognostic ...

Novel bone graft substitutes in bone tissue engineering [PDF]

Nanomedicine Journal
Objective(s): Globally, the prevalence of bone illnesses and diseases has been significantly rising. Bone tissue engineering (BTE), which can be produced continuously and doesn’t transmit disease, has been suggested as a possible alternative to the ...
