AI Article Synopsis
- The study aimed to assess the impact of 35% hydrogen peroxide bleaching on bovine teeth using two analytical methods: reflectance and FT-Raman spectroscopy.
- Prior research indicated that hydrogen peroxide alters dental structures, but further examination was needed to clarify its effects.
- Results showed that the Whiteform-Perox Red Form gel significantly enhanced enamel reflectance and reduced dental organics, particularly affecting type I collagen, while not altering key inorganic components of the enamel.
Article Abstract
Objective: To evaluate the effects of 35% hydrogen peroxide bleaching on bovine teeth using reflectance and Fourier transform (FT)-Raman spectroscopy.
Background Data: Previous investigations have shown that hydrogen peroxide can modify dental components, but more studies are necessary to comprehend its effects.
Materials And Methods: Forty bovine enamel fragments (4.0x4.0x4.0 mm) were divided into four experimental groups according to the hydrogen peroxide gel manufacturer's application: G1-Whiteness HP Maxx, G2-Whiteness HP, G3-Whiteform- Perox Red Form, G4-Opalescence Xtra. All groups were activated using a light-emitting diode-laser system. The bleaching treatments were performed in two sessions with a 72-h interval between sessions. The reflectance and Raman analyses of the enamel samples were performed before and after bleaching. The analyses before treatments were used as control.
Results: Enamel reflectance was significantly greater after the bleaching in group G3 than in groups G1, G2, and G4 (p<0.01). FT-Raman spectroscopy data showed no significant chemical changes in the inorganic components for the tested groups (p>0.05). Hydrogen peroxide gel caused significant reduction of the dental organics associated with type I collagen vibration only in group G3 (p<0.05).
Conclusion: Under the conditions of this study, 35% hydrogen peroxide Whiteform-Perox Red Form gel, exhibited great bleaching potential. This highly concentrated hydrogen peroxide gel significantly changed the reflectance of enamel and dental organics without significant chemical changes in enamel phosphate and carbonate content.

Chromium (Cr) is an ever-present abiotic stress that negatively affects crop cultivation and production worldwide. High rhizospheric Cr concentrations inhibit nutrients uptake and their translocation to aboveground parts, thus can affect the growth and development of crop plants. This experiment was designed to evaluate the effects of sole and combined zinc-lysine and iron-lysine applications on photosynthetic efficacy, antioxidative defense, oxidative stress, and nutrient uptake and translocation under Cr stress.

Abscisic acid (ABA) mediated stomatal closure is a highly effective mode of active stomatal regulation under drought stress. Previous studies on stomatal regulation have primarily focused on the leaves of vascular plants, while research on the stomatal behavior of bulbous plants remains unknown. In addition, ABA-induced stomatal regulation in bulbs has yet to be explored.

Objective: This study aims to elucidate the mechanisms by which nanovesicles (NVs) transport curcumin(CUR) across the blood-brain barrier to treat hypothalamic neural damage induced by heat stroke by regulating the expression of poly(c)-binding protein 2 (PCBP2).
Methods: Initially, NVs were prepared from macrophages using a continuous extrusion method. Subsequently, CUR was loaded into NVs using sonication, yielding engineered cell membrane Nanovesicles loaded with curcumin (NVs-CUR), which were characterized and subjected to in vitro and in vivo tracking analysis.
