Design and Development of Novel Airway Device for Transoral Respiratory Monitoring During Sedation

The Laryngoscope, EarlyView.
This article describes iterative design factors and results of clinical testing for a novel medical device that promotes transoral respiratory gas exchange for patients during sedation. A minimally viable prototype was 3D printed from thermoplastic polyurethane and demonstrated high levels of oral retention, gas exchange, and satisfaction among ...

Hunting Strategies and Game Exploitation Organization in the Magdalenian: An Integrated Approach Based on Mortality Profiles and Stable Isotopes at Chaves Cave (Huesca, Spain)

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT Understanding hunting strategies in Upper Paleolithic contexts remains challenging due to the complex relationships between prey behavior, environmental conditions, and human decision‐making. Addressing these dynamics requires integrating archeozoological, geospatial, and geochemical proxies capable of capturing demographic patterns, landscape

Comparison of the Effect of PRP, PRF and Induced Bleeding in the Revascularization of Teeth with Necrotic Pulp and Open Apex: A Triple Blind Randomized Clinical Trial

JOURNAL OF CLINICAL AND DIAGNOSTIC RESEARCH, 2017
Treatment of a tooth with necrotic pulp and open apex is a special challenge to the clinicians. Apexification with calcium hydroxide and MTA barrier technique fails to induce continued root maturation which makes the tooth susceptible to root fracture.

Comparison of Residual Triple Antibiotic Paste, Propolis and Calcium Hydroxide on Root Canal Walls in Natural Open Apex Teeth: An In Vitro Study.

Iranian endodontic journal, 2018
Endodontic therapy is challenging in open apex teeth. One of these problems is the residue of medicaments on root canal walls. The aim of this study was to evaluate the amount of residual materials on canal walls after the use as medicaments within natural open apex teeth.A total of 45 human extracted single-rooted premolars with open apices were ...

Innovative 3D‐bioprinted microfibers in calcium phosphate cement platform with Nell‐1 to activate nerve‐bone axis for synergistic bone, vasculature, and nanofibrous nerve regeneration

Smart Molecules, EarlyView.
A 3D‐bioprinted platform with stem cells activates “nerve‐bone” signaling by enabling the spatiotemporal delivery of Nell‐1. This activation enhances neurovascular and bone regeneration through the CYFIP1 cascade. In rat calvarial defects, the platform doubled bone regeneration and nerve repair and tripled vascular density, resulting in superior ...
