Targeting the Next Generation of Deep-Ultraviolet Nonlinear Optical Materials: Expanding from Borates to Borate Fluorides to Fluorooxoborates.

Accounts of Chemical Research, 2019
Coherent light radiation down to the deep-ultraviolet spectral range (λ < 200 nm) produced by common laser sources is extensively used in diverse fields ranging from ultrahigh-resolution photolithography to photochemical synthesis to high-precision ...

Fluoride intake of infants living in non-fluoridated and fluoridated areas [PDF]

British Dental Journal, 2014
Data on fluoride exposure of infants are sparse. This study aimed to estimate total daily fluoride intake (TDFI) of infants aged 1-12 months, living in non-fluoridated and fluoridated areas in north-east England.Daily dietary fluoride intake was assessed using a three-day food diary coupled with analysis of fluoride content of food/drink consumed ...

Content of Fluorine in Drinking Water in FYR Macedonia

Balkan Journal of Dental Medicine, 2014
From all the methods applied in preventing dental caries, the most significant is the use of fluorides. Nowadays, 6 decades after its massive use, it can certainly be argued that it is the most efficient, cheapest and safest way of preventing dental ...

Determination of fluoride content in drinking water and tea infusions using fluoride ion selective electrode [PDF]

Journal of Agricultural Sciences (Belgrade), 2007
Potentiometric analysis of fluoride content (as F- ion) in solutions by using fluoride ion-selective electrode is simple, reliable and cheap. Very small concentrations of fluoride-ions (to 10-6 mol/dm3) can be determined by fluoride selective electrode ...

The Fluoride Debate: The Pros and Cons of Fluoridation [PDF]

Preventive Nutrition and Food Science, 2018
Fluoride is one of the most abundant elements found in nature. Water is the major dietary source of fluoride. The only known association with low fluoride intake is the risk of dental caries. Initially, fluoride was considered beneficial when given systemically during tooth development, but later research has shown the importance and the advantages of ...

Effect of zinc oxide nanoparticles on physical and antimicrobial properties of resin-modified glass ionomer cement

Dental Research Journal, 2021
Background: To improve the limitations, many modifications in the resin-modified glass ionomer (RMGI) composition have been proposed. In this study, we evaluated the effect of different concentrations of zinc oxide (ZnO) nanoparticles incorporated into ...

C‐mannosylation promotes ADAMTS1 activation and secretion in human testicular germ cell tumor NEC8 cells

FEBS Letters, EarlyView.
C‐mannosylation is a unique form of protein glycosylation. In this study, we demonstrated that ADAMTS1 is C‐mannosylated at Trp562 and Trp565 in human testicular germ cell tumor NEC8 cells. We found that C‐mannosylation of ADAMTS1 is essential for its secretion, processing, enzymatic activity, and ability to promote vasculogenic mimicry. These findings

Synthesis of Sulfonyl Fluorides from Sulfonamides

Annalen der Pharmacie, 2020
A simple and practical synthesis of sulfonyl fluorides from sulfonamides is reported. The method capitalizes on the formation of the sulfonyl chloride by virtue of the reaction of Pyry-BF4 and MgCl2, and subsequent in situ conversion to the more robust ...

Structural dynamics of the plant hormone receptor ETR1 in a native‐like membrane environment

FEBS Letters, EarlyView.
The present study unveils the structural and signaling dynamics of ETR1, a key plant ethylene receptor. Using an optimized nanodisc system and solution NMR, we captured full‐length ETR1 in a native‐like membrane environment. Our findings reveal dynamic domain uncoupling and Cu(I)‐induced rigidification, providing the first evidence of metal‐triggered ...
