Purpose: To assess whether particles from metal and other alloplastic materials detected in tissues surrounding dental implants could have other sources of origin besides biotribocorrosion or detachment from the implant surface.
Materials And Methods: A total of 52 prostheses were randomly tested at various stages of manufacture. Identification of the detached microparticles was performed using light field microscopy and comparison with previously obtained microscopic images.
Results: Microparticles of metallic, ceramic, plaster, polishers, or unidentifiable origin were detected in 49 prostheses (94%).
Conclusion: Without an exhaustive decontamination protocol, prostheses and abutments carry metal microparticles and microparticles of other origins that could contribute to the development of peri-implant pathologies.

This study evaluated the feasibility of using ferrous sulfate microparticles (FSM), produced through the combination of spray drying and spray chilling techniques, to fortify plant-based yogurt and increase dietary iron intake. The stability of FSM was assessed, and iron bioavailability was estimated using the standardized INFOGEST in vitro digestion method, followed by Caco-2 cell culture assays. FSM showed moisture content and water activity (Aw <0.

Sorting and isolating specific cells from heterogeneous populations are crucial for many biomedical applications, including drug discovery and medical diagnostics. Conventional methods such as Fluorescent Activated Cell Sorting (FACS) and Magnetic Activated Cell Sorting (MACS) face limitations in throughput, cost, and the ability to separate subtly different cells. Cell partitioning in Aqueous Two-Phase Systems (ATPSs) offers a biocompatible and cost-effective alternative, particularly when combined with continuous-flow microfluidics.

Complex crater formation is an incompletely understood phenomenon, referring to instances wherein a high-speed projectile impacts a surface and leaves a crater characterized by a central uplift. We elucidate the mechanism of complex crater formation by examining crater formation on different polymer substrates resulting from microparticle impacts with tunable microparticle diameter (1.8 to 6.

is an aromatic plant of Mediterranean origin traditionally used to treat inflammatory, cardiovascular, endocrine, and digestive diseases. In this work, the ability of the extract in the treatment of gastric ulcers was evaluated, and an innovative administration system was proposed to increase the therapeutic effect of this plant. ethanolic extract was prepared and analyzed by HPLC/UV-DAD and encapsulated in a matrix based on gelatin and pectin using an emulsion-coacervation process.
