A recent traffic fatality has been attributed to the use of the drug methylenedioxymethamphetamine (MDMA). The deceased was a 29-year-old white male with no known history of drug abuse. Toxicological analysis detected MDMA and metabolite methylenedioxyamphetamine (MDA) in the blood, urine, and vitreous humor specimens submitted for analysis. The concentrations of MDMA in clotted blood, sodium f...

Ample evidence is available that body fluids other than serum contain antibodies (Coleman and Appleman, 1953; Kanter and Appleton, 1940; Klauder and Kolmer, 1921). Occasionally (Biro, 1947) these fluids reveal antibodies more frequently and sooner after infection of the bone marrow in syphilis. Plasma also has an antibody content (Addis, 1912; Cowie, 1909; Gurd, 1912), although some anti-coagul...

SYNTHESIS 2006, No. 19, pp 3316–3340xx.xx.2006 Advanced online publication: 06.09.2006 DOI: 10.1055/s-2006-950231; Art ID: C04506SS © Georg Thieme Verlag Stuttgart · New York Abstract: A combination of palladium(II) acetate, aqueous potassium fluoride, and polymethylhydrosiloxane (PMHS) facilitates the room-temperature reduction of aromatic nitro compounds to anilines. These reactions tend to b...

The KF, sucrose (table sugar) exploited as quenching system in solution phase parallel synthesis. Excess of electrophiles were covalently trapped with hydroxyl functionality of sucrose and due to polar nature of sucrose derivative was solubilize in water. Potassium fluoride used to convert various excess electrophilic reagents such as acid chlorides, sulfonyl chlorides, isocyanates to correspon...

A novel yet simple, rapid and robust thermometric endpoint titration (TET) method for the determination of sodium in various foodstuffs is described. Sodium reacts exothermically with aluminium in the presence of an excess of potassium and fluoride ions to form NaK2AlF6 (“elpasolite”). This reaction forms the basis of a robust, reliable analytical procedure suitable for routine process control....

To compare the effect of bioavailable gluconate-chelated stannous fluoride (SnF2) toothpaste with control toothpastes for treatment dentine hypersensitivity (DH) and enamel erosion. A Procter & Gamble Oral Care archive clinical studies was reviewed from 2000 to 2020. Eligible were Randomised Controlled Trials (RCTs) investigating SnF2 efficacy compared controls in adult participants measured fo...

Springs are abundant and present worldwide among the most threatened ecosystems on Earth. The main aim of this study was to evaluate biodiversity seventy-nine (79) mineral saline springs situated in French Massif Central, focusing species richness estimated also diatom community composition. influence physical chemical factors both communities analyzed order have a better knowledge ecological p...

statement of the problem generally, the main source of fluoride intake is drinking water. excessive consumption of bottled water as a substitute or in addition to the tap water supply may have implications for safe fluoride supplementation. in this study, fluoride contents in six commercial brands of bottled water were measured materials and methods six different brands of bottled drinking wate...

Groundwater is prime and major source of drinking water in our world. Jharkhand also used for drinking, domestic, irrigation, mining industrial etc. purposes. In some population are suffering from scarcity pure have partial facility with as groundwater many area contaminated fluoride, arsenic, heavy metals iron dangerous chemicals. This review paper focuses on current status contamination diffe...
