AI Article Synopsis
- The study aimed to compare four different protocols for removing fluorescent materials left on enamel surfaces after orthodontic bracket debonding.
- Results indicated that the fluorescent lens (FL) protocol was the most effective for reducing resin residue and enamel thickness, while the conventional (C) and white LED (W) methods left more resin but caused less damage to the enamel.
- The study concludes that using auxiliary devices, particularly ones that enhance fluorescence, can significantly improve the removal of leftover materials post-debonding.
Article Abstract
Objective: To evaluate four protocols for removal of fluorescent materials after bracket debonding.
Materials And Methods: Resin removal from 40 bovine enamel surfaces was performed according to groups (n = 10): conventional (C), white LED (W), LED that evidenced fluorescence (F), and fluorescent lens (FL). The following analyses were performed: sample thickness, superficial area of resin residue, and areas of resin residue or worn enamel in depth. ANOVA and Tukey tests were used to analyze sample thickness (P ≤ .05). Area measurements were analyzed by Kruskal-Wallis and Dunn's tests (P ≤ .05).
Results: The FL group showed the highest reduction in enamel thickness. F group final thickness was similar to that of other groups. The largest superficial areas of resin residue were found for the C and W groups, while the FL group had the greatest removal of resin residue. The C group exhibited the largest area in depth of resin residue. The FL and F groups exhibited the most loss of enamel with the least amount of resin residue; in contrast, the C and W groups presented the fewest areas of worn enamel and the most areas of resin residue.
Conclusion: Auxiliary devices were useful for removal of fluorescent residue after bracket debonding.

Diethylene glycol dimethacrylate (DEG)-crosslinked polystyrene (PS) resin offers a promising alternative to traditional divinyl benzene (DVB)-PS resin for solid-phase peptide synthesis (SPPS), particularly for challenging sequences with hydrophobic or bulky amino acids. DEG-PS resin's reduced hydrophobicity and enhanced flexibility improve synthesis efficiency, yielding peptides up to 28 residues with higher purities and yields compared to DVB-PS. In various syntheses, DEG-PS outperformed DVB-PS resin, with higher purities and yields for challenging peptides such as ABC analogue (73.

Waterborne polyurethane (WPU) was cured with a flame retardant composed of polydimethylsiloxanes and boron phenolic resin. In comparison to unmodified WPU, the heat resistance of the cured WPU film was significantly improved by approximately 40.0 °C, and the limited oxygen index (LOI) increased from 21.

The study of biomolecules and their interactions in their natural environment requires increasingly sophisticated technological and methodological developments. The complexity of these developments is due, among other things, to the nature of these molecules and the small quantities available depending on their origin. In this context, this study focuses on the conditions for improving the detection of glycosaminoglycans on a miniaturized scale by mass spectrometry.

Alzheimer's disease (AD), a multifactorial neurodegenerative disorder characterized by severe cognitive impairment, affects millions of people worldwide. However, AD therapy remains limited and mainly symptomatic-focused, with acetylcholinesterase (AChE) inhibitors being the major available drugs. Thus, AD is considered by the WHO as a disorder of public health priority.

Article Synopsis
- A hydrogel was created using mung bean protein isolate and κ-carrageenan to encapsulate propolis at two concentrations (1% and 3% w/v).
- The study evaluated the hydrogel's rheological properties and texture, revealing that encapsulation did not alter its chewiness, adhesiveness, or hardness.
- Various techniques confirmed strong electrostatic and covalent interactions in the hydrogel, with results indicating it efficiently encapsulates propolis, boasting over 99% encapsulation efficiency and significant antioxidant activity.
