Nanoparticle superlattice with a C14 Frank-Kasper structure formed by highly monodisperse one-size gold nanoparticles in suspension.

Synthesizing nanoparticle superlattices (NPSLs) with different symmetries is of great interest due to their impact on the collective emergent properties and potential applications. While several parameters have been identified as determinants for forming different symmetries of NPSLs, the high core dispersity, softness, and ligand interpenetration were proposed to drive the formation of the C14 Frank-Kasper (C14) structure like MgZn-type. Here, we report that the C14 phase can be formed in highly monodisperse one-size spherical nanoparticles (NPs) by controlling the interplay among their softness and ligand grafting density.

Influence of orthodontic bracket block-out materials on superimposition errors when substituting scanned dental imaging data onto computed tomography images.

Purpose: The study was performed to examine the error associated with image superimposition when computed tomography (CT) images of the dental region are substituted with dental scan data, according to the block-out material used in dental impressions.

Materials And Methods: A typodont model was created by bonding orthodontic brackets to teeth on plaster dental stones using melted dental base-plate wax. In the experiment, 2 groups were compared: one using wax and the other using putty as the block-out material to prevent tearing of the impression material during the acquisition of dental impressions.

Pedicle ossification following mandibular reconstruction using fibular free flap in a patient with osteoradionecrosis of the jaw: a case report.

Pedicle ossification is a rare but significant complication following mandibular reconstruction using a fibular free flap (FFF), a technique widely employed in maxillofacial surgery due to its reliable vascularized bone supply and low donor site morbidity. The FFF supports dental implantation and prosthetic rehabilitation, with its vascularized periosteum enhancing osteogenic potential. Despite these advantages, unexpected ossification of the flap's vascular pedicle may occur, potentially mimicking tumor recurrence and causing diagnostic uncertainty.

Initial Magnetic Resonance Imaging Findings in Hepatic Fascioliasis and Serological and Radiological Response After Triclabendazole Treatment.

Fascioliasis, a food-borne trematodiasis, is a disease primarily identified in livestock, such as sheep and cattle. Human fascioliasis has been reported sporadically in Korea, but a recent increase in patients has been associated with a green vegetable juice delivery service. We aimed to investigate the serological and radiological findings of the patients treated for fascioliasis.
