Study on the Antibacterial Properties and Optical Characteristics of Clear Orthodontic Aligners Coated With Zinc Oxide and Magnesium Oxide Nanoparticles.
Orthod Craniofac Res
January 2025
Dental Materials Research Center, Health Research Institute, Babol University of Medical Sciences, Babol, I.R.Iran.
Objectives: This study aimed to evaluate and compare the antibacterial properties and optical characteristics of clear orthodontic aligners coated with zinc oxide (ZnO) and magnesium oxide (MgO) nanoparticles.
Materials And Methods: In this experimental laboratory study, polyethylene terephthalate glycol (PETG) aligner samples were coated with nanoparticles of ZnO, MgO and a combination of both (ZnO + MgO). The surface coatings were analysed before and after stability testing using field emission scanning electron microscopy (FESEM).
Synthesis and antifungal activity of arecoline derivatives containing amino acid fragments.

School of Nuclear Technology and Chemistry & Biology, Hubei University of Science and Technology, Xianning, 437100, China.
A series of new arecoline derivatives containing amino acid fragments were synthesized, and their fungicidal activities were investigated. All synthesized compounds were characterized by H NMR, CNMR, and HRMS. Preliminary bioactivity assays demonstrated that Compounds 3k, 3n, 3p, 3q, 3r, and 3s exhibited significant antifungal activity against Botryosphaeria cactivora, Botryosphaeria dothidea, and Fusarium pseudograminearum at a concentration of 100 μg/mL.

Department of Medical Parasitology, Faculty of Medicine, Zagazig University, El Kawmia Square, Zagazig, Sharkia Governorate, Egypt.
Purpose: Trichinellosis affects around 11 million people globally. Treatments for this medical condition are limited by adverse effects and resistance, emphasising the importance of effective and safe therapies. Consequentially, we sought to study colchicine's synergistic effects with atorvastatin or acetazolamide in the treatment of Trichinella spiralis (T.

Implants aim to restore skeletal dysfunction associated with ageing and trauma, yet infection and ineffective immune responses can lead to failure. This project characterized the microbiological and host cell responses to titanium alloy with or without electroplated metallic copper. Bacterial viability counting and scanning electron microscopy quantified and visualized the direct and indirect bactericidal effects of the Cu-electroplated titanium (Cu-Ep-Ti) against two different Staphylococcus aureus strains.

The multiple-tentacle box jellyfish, (Sucharitakul, 2017) and (Horst, 1907), are venomous species found in Thai waters. They are responsible for numerous envenomations through their stinging organelles, nematocysts. These specialized microscopic structures discharge venom, yet detailed knowledge of their types and morphology in these species remains limited.
