Article Abstract
Purpose: To investigate the ability of the smart denture conversion (SDC) technique to produce a stronger interim full-arch implant restoration.
Materials And Methods: Three materials (OnX Tough 3D-printed resin, milled PMMA, and injection molded PMMA) were used to fabricate 180 specimens, 60 specimens per material. Then, an equal number of specimens were assigned a conversion technique: either traditional denture conversion or smart denture conversion. The conversions were performed on a pickup jig containing two multiunit abutment replicas. Acrylic resin was used as the pickup material. After denture conversions were performed, all specimens had uniform dimensions. To evaluate mechanical strength, each specimen underwent a 3-point bend test using an Instron machine with static load testing. Data analysis employed a two-way ANOVA considering material type, method of conversion, and their interaction, with Tukey HSD post hoc tests conducted in STATA 18.0, where significance was set at p < 0.05.
Results: Results from this study are described as method of conversion, material, and the combination of method of conversion and material. The method of conversion was statistically significant for mean fracture strength, resulting in a p-value < 0.037. Choice of material showed statistically significant results for mean fracture strength, with a p-value < 0.000. The combination of method of conversion and material showed a statistically significant result for mean fracture strength with a p-value < 0.000.
Conclusion: Out of 180 specimens, the combination of OnX Tough 3D-printed specimens converted with smart denture conversion yielded the highest mean fracture strength and the highest individual fracture strength value.

Silver nanoprisms (AgNPrs) are promising candidates for surface-enhanced Raman scattering (SERS) due to their strong localized surface plasmon resonance and sharp tip geometry. In this study, AgNPrs were synthesized through a photochemical method by irradiating spherical silver nanoparticle seeds with 10 W green light-emitting diodes (LEDs; 520 ± 20 nm) for various periods of time up to 72 h. The growth mechanism was investigated through ultraviolet-visible spectroscopy, field-emission scanning electron microscopy, X-ray diffraction, and transmission electron microscopy analyses, confirming the gradual transformation of spherical seeds into AgNPrs.

This work elucidates the thermo-kinetics of the thermal conversion of cameroonian kaolin to metakaolin as the main product. The thermokinetical parameters (activation energy and pre-exponential factor ) for the kaolin conversion were calculated using model-free methods, the Kissinger-Akahira-Sunrose (KAS) and the Flynn-Wall-Ozawa (FWO) method, and differential methods (Kissinger and Ozawa) additionally including iterative procedures for KAS and FWO methods (KAS-Ir; FWO-Ir). The cameroonian kaolin was heat-treated using three different heating rates, 5, 20 and 40 K min, leading to metakaolin samples named MK-(5), MK-(20) and MK-(40).

Introduction: Tenvermectin (TVM) is a novel avermectin-class drug that has attracted attention for its superior antiparasitic potency, low toxicity, and broad-spectrum activity. However, uncertainty about its interaction with cytochrome P450 enzymes (CYPs) has raised concerns about potential therapeutic failure, increased risk of toxicity, dangerous drug combinations, and prolonged discontinuation periods.
Method: To address these critical safety concerns, we conducted a systematic comparative study using a highly selective and quantitatively accurate substrate conversion assay to assess and compare the effects of TVM and ivermectin (IVM) on the activities of key CYPs (CYP1A1/2, 2B1, 2C6, 2D2, and 3A1/2).
Mitigation of mycotoxin residues and activation of endogenous stem cells in broiler chickens using a toxin binder: Implications for meat safety and performance enhancement.

Background And Aim: Mycotoxin contamination in poultry feed, particularly with aflatoxin B1 (AFB1) and ochratoxin A (OTA), poses significant threats to broiler health, meat quality, and consumer safety. Toxin binders are commonly used to mitigate these effects; however, their impact on endogenous stem cell activity and overall broiler performance remains underexplored. This study aimed to evaluate the efficacy of a commercial toxin binder in reducing AFB1 and OTA residues in broiler meat, inducing endogenous stem cell production, and improving growth and feed performance indices.
