Accumulator plants and hormesis
Highlights The literature of hyperaccumulators dose response was reviewed. Hormetic dose-response relationships were commonly observed for multiple chemicals. Quantitative features of the hormetic dose response were similar across studies. Hormetic stimulation was related to metal accumulation in the plant tissues. Dose-responses were associated with up- and down-regulation of adaptive mechanisms. Abstract Accumulation of metals by […]

Smartphone as a simple device for visual and on-site detection of fluoride in groundwater
Highlights 1 was prepared as a self-calibration fluoride probe. The detection limit of 1 toward fluoride is as low as 2.09 ppb. Fluoride detection is based on the triggered Si-O cleavage driven ESIPT process. Smartphone as a device was prepared for visual and on-site detection of fluoride. Abstract Developing a portable device for visual and […]

Study shows the possibility of fluorine substituting lithium when manufacturing rechargeable batteries
The scarcity of cobalt and lithium is undebatable. That has been a challenge since they are essential components of modern batteries. With people transforming towards a zero-emission globe, the demand for modern batteries will only increase significantly because of electric vehicles. That’s why researchers saw the need to look for another alternative for this rare […]

Open-Source Portable Device for the Determination of Fluoride in Drinking Water
Abstract The prolonged exposure to fluorides results in the development of several diseases, from dental fluorosis to crippling deformities of the spine and major joints. The population exposed to high fluoride concentration is located in developing countries where the assurance of water quality is difficult to perform. Addressing this challenge, an open-source system for the […]

Dr.Collins BioMin Restore Plus: the first ever fluoride-containing bioglass toothpaste to get FDA approval
Dr.Collins is delighted to announce that its BioMin Restore Plus Toothpaste has received FDA 510K approval for relief of sensitivity. This is a huge breakthrough, being the first fluoride-containing bioactive glass toothpaste to be approved by the FDA for sale in the United States *(see footnote). The toothpaste uniquely controls the release of calcium, phosphate […]

PFAS Chemical Associated With Severe Covid-19
Note from Fluoride Action Network Molecular structure of PFBA (Pentafluorobenzoic acid) C6F5CO2H Ref: Wikipedia A Danish study found that people with elevated levels of a compound called PFBA were more than twice as likely to have a severe form of Covid-19. Elevated levels of a PFAS compound were associated with more severe forms of Covid-19, […]

Potential of preparing cement clinker by adding the fluorine-containing sludge into raw meal
Highlights A sustainable treatment of hazardous fluoride containing sludge was proposed. Fluorine-containing sludge improved burnability, mineral morphology and properties of produced clinker. Fluorine was combined with calcium in produced clinker and hydration products. Fluorine-containing sludge from semiconductor industries were one kind of hazardous wastes, there was hardly effective treatment to realize its safe disposal and […]

Comparison of new formulas of stannous fluoride toothpastes with other commercially available fluoridated toothpastes: A systematic review and meta-analysis of randomised controlled trials
Excerpts: Aim: The aim of this study was to systematically review and analyse the difference in efficacy of stannous fluoride toothpaste formulations in comparison to other fluoridated toothpastes without stannous fluoride. Materials and methods: A systematic search of the literature was performed according to PRISMA guidelines. A search strategy was developed to answer the study […]

Repeated low-dose exposures to sarin disrupted the homeostasis of phospholipid and sphingolipid metabolism in guinea pig hippocampus.
Note from FAN: The molecular structure of Sarin: Highlights Repeated low-dose sarin disturbed the cognitive ability in guinea pigs. Sarin disturbed phospholipid and sphingolipid metabolism in hippocampus. Neuropathy target esterase plays an important role on phospholipid metabolism. Biological function of identified metabolites that against sarin lesions need to be studied. Abstract Repeated low-level exposure to […]
