A novel, I2 catalyzed regio- and stereodivergent vicinal azidohydroxylation of alkenes leading to 1,2-azidoalcohols in high yields (up to 92%) and excellent dr (up to 98%) has been developed. This unprecedented transformation employs NaN3 and DMF as N- and O-nucleophiles respectively. The role of DMF as the O-source in the reaction has been unequivocally proven by (18)O labelling studies.
The purpose of this article is to study distribution of DMF(T) and its D,M and F protions exactllly. 1500 subjects were examined clinicaly. They were 5 to 70 years old, with average 24 years. Only cavitated and coronal dental caries included in this research. The results of this study are:1. The caries lesions of upper and lower second permolars are equal.2. Anterior to second premolars, the DM...
The title compound, (C(8)H(20)N)(2)[Cu(5)(C(7)H(4)NO(3))(4)(C(3)H(7)NO)(2)], abbreviated as (TEA)(2)[Cu(II)(12-MC(Cu(II) ) (N(shi))-4](DMF)(2) [where TEA is tetra-ethyl-ammonium, shi(3-) is salicyl-hydroximate (or N,2-dioxidobenzene-1-carboximidate) and DMF is N,N-dimethyl-formamide], contains five Cu(II) ions. Four of the Cu(II) ions are members of a metallacrown ring (MC), while the fifth Cu(...
BACKGROUND AND PURPOSE Significant effects on clinical/neuroradiological disease activity have been reported in patients with relapsing-remitting multiple sclerosis treated with delayed-release dimethyl fumarate (DMF) in phase III DEFINE/CONFIRM trials. We conducted a post hoc analysis of integrated data from DEFINE/CONFIRM to evaluate the effect of DMF on achieving no evidence of disease activ...
Lignocellulosic biomass is an attractive resource for producing transportation fuels, and consequently novel approaches are being sought for transforming the lignin and cellulosic constituents of biomass to fuels or fuel additives. Glucose, the monomer of cellulose, is a good starting material for exploring such chemistries. We report here the results of an investigation aimed at identifying ca...
مقدمه: پوسیدگی دندانی شایع ترین بیماری عفونی و قابل انتقال دندان ها است. شاخص sic (significant caries index) یکی از شاخص هایی است که توسط سازمان بهداشت جهانی با هدف تعیین افرادی که بالاترین مقادیر dmft (decay, missing, filling, teeth) را دارند، معرفی شده است. هدف از این مطالعه ارزیابی میزان شاخص های sic و dmft در دانش آموزان پسر 12 ساله شهرستان سیرجان بود. مواد و روش ها: در این مطالعه مقطعی توص...
introduction: permanent first molar is the most important unit in the chewing system. ear-ly loss of first molars can significantly reduce chewing efficiency, increase overbite, lead to premature eruption of the permanent second and third molars, and displacement of adjacent teeth. the purpose of this study was to determine the associated factors of permanent first molar caries in 7-9 years old...
N,N-Dimethylformamide (DMF), a colorless liquid with a high boiling point, is a solvent used in a large number of industrial processes. Male and female F344/N rats (30/sex/group) and B6C3F1 mice (10/sex/group) were exposed to DMF vapors at concentrations of 0, 50, 100, 200, 400, or 800 ppm, 6 hours/day, 5 days/week, for 13 weeks in whole body exposure inhalation studies. In addition to histopat...
Dimethyl fumarate (DMF) possesses anti-inflammatory properties and is approved for the treatment of psoriasis and multiple sclerosis. While clinically effective, its molecular target has remained elusive - although it is known to activate anti-oxidant pathways. We find that DMF inhibits pro-inflammatory cytokine production in response to TLR agonists independently of the Nrf2-Keap1 anti-oxidant...
