COMMBINI: an experimentally-informed COmputational Model of Macrophage dynamics in the Bone INjury Immunoresponse.

Bone fracture healing is a well-orchestrated but complex process that involves numerous regulations at different scales. This complexity becomes particularly evident during the inflammatory stage, as immune cells invade the healing region and trigger a cascade of signals to promote a favorable regenerative environment. Thus, the emergence of criticalities during this stage might hinder the rest of the process.

The Bone-Forming Properties of Periosteum-Derived Cells Differ Between Harvest Sites.

The development of alternatives for autologous bone grafts is a major focus of bone tissue engineering. To produce living bone-forming implants, skeletal stem and progenitor cells (SSPCs) are envisioned as key ingredients. SSPCs can be obtained from different tissues including bone marrow, adipose tissue, dental pulp, and periosteum.

Is there need for technical investigations in order to predict potential length of hospital stay of oral infections?

Objective: Oral and maxillofacial infections are generally treated by primary dental or medical caregivers. Nevertheless, because these infections are known to have life-threatening complications, there is a need of clear indicators for emergency services medical staff, particularly in determining when morbidity can be expected and when in-hospital treatment is required. This retrospective study aimed to identify variables that were observable at admission, which could indicate high complication rates, long hospital stays, and/or a need for tracheostomy.

Hyperbaric oxygen therapy as a prevention modality for radiation damage in the mandibles of mice.

Background: Radiation therapy (RT) as part head and neck cancer treatment often leads to irradiation of surrounding normal tissue, such as mandibular bone. A reduced reparative capacity of the bone can lead to osteoradionecrosis (ORN). Hyperbaric oxygen therapy (HBOT) is used to treat ORN, based on its potential to raise the oxygen tension in tissues.

Enamel Matrix Derivative has No Effect on the Chondrogenic Differentiation of Mesenchymal Stem Cells.

Background: Treatment of large bone defects due to trauma, tumor resection, or congenital abnormalities is challenging. Bone tissue engineering using mesenchymal stem cells (MSCs) represents a promising treatment option. However, the quantity and quality of engineered bone tissue are not sufficient to fill large bone defects.
