Palatal Actinomycosis: Re-emergence of an Ancient Pathology.

Palatal actinomycosis is a rare chronic infectious disease primarily caused by Actinomyces species. Here, we present case reports of two immunocompromised patients with palatal actinomycosis. This paper highlights the clinical presentation, diagnosis, management, and potential complications.

An Emergency Department Virtual Observation Unit Fall Prevention Program: A Pilot Acceptability Study.

Background Falls are a leading cause of unintentional death among adults aged 65 and above and are associated with significant injuries and healthcare costs. Older adults frequently present to the emergency department (ED) for falls. However, ED clinicians rarely focus on preventing future falls, given the lack of time and resources.

From imaging to computational domains for physics-driven molecular biology simulations: Hindered diffusion in platelet masses.

When formed in vivo, murine hemostatic thrombi exhibit a heterogeneous architecture comprised of distinct regions of densely and sparsely packed platelets. In this study, we utilize high-resolution electron microscopy alongside machine learning and physics-based simulations to investigate how such clot microstructure impacts molecular diffusivity. We used Serial Block Face - Scanning Electron Microscopy (SBF-SEM) to image select volumes of hemostatic masses formed in a mouse jugular vein, producing large stacks of high-resolution 2D images.

Comparative Evaluation of Ozone Water and Glutaraldehyde on Surface Detail Reproduction of Vinyl Polyether Silicone Impression Materials at Different Time Intervals.

Objective: The study aims to evaluate the impact of chemical disinfection using ozone water and glutaraldehyde on the surface detail reproduction (SDR) of vinyl polyether silicone (VPES) impression material at different time intervals.

Methodology: VPES impressions were categorized into light-body and heavy-body groups and further divided based on the disinfectant used (ozone water or glutaraldehyde) and the time interval of disinfection (T1: 15 minutes and T2: 24 hours). A total of 80 impressions (40 light-body and 40 heavy-body) were prepared and subjected to the respective disinfection protocols.

Bimetallic AuPd alloy nanoparticles on TiO₂ nanotube arrays: a highly efficient photocatalyst for hydrogen generation.

Decoration of TiO2 nanotube (TNT) arrays by AuPd nanoparticles (NPs) produces a dramatic enhancement in the rate of hydrogen generation through photocatalytic water-splitting under solar illumination. XRD and TEM confirmed alloy formation in bimetallic AuPd NPs while XPS ruled out a core-shell architecture in the AuPd NPs. Well-dispersed, size-controlled AuPd NPs were formed by sequential physical vapor deposition of Au and Pd on TNTs followed by spontaneous thermal dewetting (TNT-AuPd).
