The abundant presence of fluoride (F-) in surface water bodies is an environmental concern because its effects on human health; medical reports confirmed that intake above 1.5 mg/L leads to many health complications, including but not limited weak bones and enamel fluorosis. Thus, the World Health Organisation (WHO) defines 1.20 as maximum permissible F- concentration drinking water. electrocoa...

Abstract Background Primary Health Care (PHC) is the entry point to accessing health services in many countries. Having a high proportion of population enrolled with PHC provider key ensuring fulfils this role and that it contributes achieving better equity health. We aimed understand extent which people Aotearoa New Zealand are enrolling Organizations (PHOs), how enrolment rates have evolved o...

Implanted tumors and methylcholanthrene Carcinogenesis increase the turnover of phosphorus in the total nucleic acids of histologically normal DBA/1J mouse skin. As the implanted tumors progress for 6 days, the turnover rate of nucleic acid phosphorus in the histologically normal skin increases to 4 times that of control skin from normal DBA/1J mice. At this same time, 68% of the histologically...

Ionic liquids such as 1,3-dialkylimidazolium salts make excellent catalysts and solvents for synthesis of dialkyl 2-(dialkoxyphosphoryl)-3-(1-oxo-1-H-phthalazin-2-yl)succinates from 2H-phthalazin-1-one, dialkyl acetylenedicarboxylates, and trialkyl phosphites. Under similar conditions, triphenyl phosphite led to dialkyl 2-(diphenoxyphosphoryl)-3-(1-oxo-1-H-phthalazin-2-yl)succinates. The ionic ...

Disclosed herein is the first carbene-organocatalyzed asymmetric addition of phosphine nucleophiles to in situ generated ?,?-unsaturated acyl azolium intermediates. Our reaction enantioselectively constructs carbon–phosphine bonds and prepares chiral phosphines with high optical purities. The products are suitable for transforming ligands or catalysts applications catalysis. diarylalkyl trialky...
