Objective
The aim of this study was to determine how the removal of non‐impacted third molars (N‐M3s) affects the periodontal status of neighboring second molars (M2s).
Subjects and Methods
The periodontal condition of M2s for which the neighboring N‐M3s were removed (more than 6 months previously) and those with intact N‐M3s was analyzed in a cross‐sectional observation study. In an additional...
Piliqing subbituminous coal (PSBC) was exhaustively extracted with isometric acetone/carbon disulfide mixed solvent under ultrasonic irradiation to afford extractable portion (EP) and extraction residue (RE). Then RE was subjected to sequential thermal dissolution (TD) in ethanol at 200, 240, 280, and 320°C and TD at each temperature was conducted for 2h. The sequential TD provided soluble portions...
Buliangou subbituminous coal (BSBC) was sequentially extracted under ultrasonication with petroleum ether, carbon disulfide, methanol, acetone, and isometric carbon disulfide/acetone mixed solvent to afford extracts and residue (RE) from the extraction. Then the RE was subjected to sequential thermal dissolution (TD) at 320°C with cyclohexane, benzene, methanol, ethanol, and isopropanol to afford...
Wheat straw (WS) was oxidized in a sodium hypochlorite (NaOCl) aqueous solution at 40°C followed by sequential extraction of the water-soluble fraction (WSF) with petroleum ether, carbon disulfide (CDS), diethyl ether and ethyl acetate (EA). The EA-inextractable solution was acidized and filtrated. The filtration was also sequentially extracted with the same series of solvents. In total, 38 organonitrogen...
