Enhanced Fluoride Removal Using Mg-Zr Binary Metal Oxide Nanoparticles Confined in a Strong-base Anion Exchanger
In this study, we synthesized a novel hybrid adsorbent, Mg-Zr-D213, by loading nano-Mg/Zr binary metal (hydrogen) oxides in a strong-base anion exchanger, D213, to enhance the adsorption of fluoride from neutral water. Mg-Zr-D213 exhibited a better fluoride-removal capacity in neutral water than monometallic modified resins. Under the interference of competing anions and coexisting organic acids, Mg-Zr-D213 exhibited superior selectivity. The Langmuir model indicated that the fitted maximum sorption capacity of Mg-Zr-D213 was 41.38 mg/g. The results of column experiments showed that the effective treatment volume of Mg-Zr-...

Effect of Calcium Supplementation and TMEM16A Inhibition on Endoplasmic Reticulum Stress Induced by Dental Fluorosis in Mice
CONCLUSIONS: The supplementation of calcium or the inhibition of TMEM16A expression appears to mitigate the detrimental effects of fluorosis by suppressing endoplasmic reticulum stress. These findings hold implications for identifying potential therapeutic targets in addressing dental fluorosis.PMID:38665024 | DOI:10.24976/Discov.Med.202436183.71 (Source: Discovery Medicine)

Harnessing solid-state ion exchange for the environmentally benign synthesis of high-efficiency Mn < sup > 4+ < /sup > -doped phosphors
In this study, a solid-state ion exchange (SSIE) method is proposed to synthesize a series of Mn4+-doped fluoride phosphors, which avoids the use of HF solution during the Mn4+-doping process. The obtained Mn4+-doped fluoride phosphors exhibit strong red emission with a quantum yield of 46%.PMID:38669112 | DOI:10.1039/d4cc01530d (Source: Chemical Communications)

The effect of fluoride varnish application on colour change due to paediatric drug usage in polyacid-modified composite resin: an in vitro study
ConclusionIt is thought that fluoride varnish application may be beneficial as a preservative in the colour change of polyacid-modified composite resins due to the use of various paediatric drugs, and this protective feature may be effective for a specific period of time.

Spatial Atlas for Mapping Vascular Microcalcification Using 18F-NaF PET/CT: Application in Hyperphosphatemic Familial Tumoral Calcinosis
CONCLUSIONS: This technique affords the ability to visualize spatial patterns of the active microcalcification process in the peripheral vasculature. Further, this technique affords the ability to track microcalcifications at precise locations not only across time but also across subjects. This technique is readily adaptable to other diseases of vascular calcification and may represent a significant advance in the field of vascular biology.PMID:38660800 | DOI:10.1161/ATVBAHA.123.320455 (Source: Arteriosclerosis, Thrombosis and Vascular Biology)

Hydrosilylation of olefins activated on highly Lewis-acidic calcium cation
Chemistry. 2024 Apr 25:e202401322. doi: 10.1002/chem.202401322. Online ahead of print.ABSTRACTThe report introduces simple yet highly reactive calcium salt, Ca[Al(ORF)4]2 (RF = C(CF3)3), 1, which effectively catalyses olefin hydrosilylation through an unusual mechanism involving the activation of the alkene molecule. Upon dissolution in o-difluorobenzene (oDFB), 1 forms a highly Lewis acidic [Ca(oDFB)6]2+ complex. Our DFT calculations reveal that fluoride ion affinity is comparable to SbF5. Reactivity tests show that it effectively catalyses the hydrosilylation of olefins with high regioselectivity, also in reactions invol...

The Effect of Direct Observation of Procedural Skills on Learning and Satisfaction of Students in Community Dentistry Course
CONCLUSION: The DOPS method had more impact on Fluoride therapy, pit and fissure sealant therapy, and health education's learning process in dentistry students than the conventional evaluation. The professors and students' satisfaction level was high regarding DOPS. The advantages of the DOPS method are student-centeredness, objectivity, and appropriate feedback.PMID:38660432 | PMC:PMC11036320 | DOI:10.30476/JAMP.2023.100431.1890 (Source: Adv Data)
