Metal-Assembled Collagen Peptide Microflorettes as Magnetic Resonance Imaging Agents.

Magnetic resonance imaging (MRI) is a medical imaging technique that provides detailed information on tissues and organs. However, the low sensitivity of the technique requires the use of contrast agents, usually ones that are based on the chelates of gadolinium ions. In an effort to improve MRI signal intensity, we developed two strategies whereby the ligand DOTA and Gd(III) ions are contained within Zn(II)-promoted collagen peptide () supramolecular assemblies.

Artificial intelligence for oral and maxillo-facial surgery: A narrative review.

Artificial Intelligence (AI) is a set of technologies that simulate human cognition in order to address a specific problem. The improvement in computing speed, the exponential production and the routine collection of data have led to the rapid development of AI in the health sector. In this review, we propose to provide surgeons with the essential technical elements to help them understand the possibilities offered by AI and to review the current applications of AI for oral and maxillofacial surgery (OMFS).

New surgical method of tongue reduction for macroglossia: technical note.

Objective: We describe here a new surgical technique, which allows for efficient tongue reduction with satisfactory appearance and avoids the complications of tip excision.

Study Design: This is a retrospective case review that includes 6 patients who had macroglossia and underwent tongue reduction using our new central V-shaped excision technique. Three patients were operated on at an early age because of significant macroglossia with permanent tongue protrusion, cosmetic disorder, and speech delay.

Osteomyelitis of the jaws: A retrospective series of 40 patients.

Introduction: The caseload of jaw osteomyelitis seem to have decreased considerably over the last fifty years thanks to the progress of oral hygiene, the appearance and the use of antibiotics, and early screening. 'Limited osteitis' remains frequent in general practice (alveolitis after dental extraction), but osteomyelitis is much rarer as evidenced by the lack of current literature and the low number of reported patients in the published series. The aim of this study was to analyze retrospectively all the cases of maxillo-mandibular osteomyelitis treated in a large academic department of Stomatology and Maxillofacial Surgery over a period of 6 years and to compare the results to data from the literature.

Worm-Like Superparamagnetic Nanoparticle Clusters for Enhanced Adhesion and Magnetic Resonance Relaxivity.

Nanosized bioprobes that can highlight diseased tissue can be powerful diagnostic tools. However, a major unmet need is a tool with adequate adhesive properties and contrast-to-dose ratio. To this end, this study demonstrates that targeted superparamagnetic nanoprobes engineered to present a worm-like shape and hydrophilic packaging enhance both adhesion efficiency to target substrates and magnetic resonance (MR) sensitivity.
