The arm repeat-containing 1 (ARC1) and the skp1-cul1-F-box proteins, belonging to the family of E3 Ub ligases, function in both the sporophytic and gametophytic self-incompatible responses, respectively.
自交不亲和反应也正是通过此途径实现的,ARC1(arm repeat containing 1)和SCFs (skp1-cul1-F-box-proteins)作为E3s分别在孢子体自交不亲和和配子体自交不亲和反应中起作用。

When Gluma is applied in vivo, two reactions occur: first, GA reacts with part of the serum albumin in dentinal fluid, which induces a precipitation of serum albumin; and, second, the reaction of GA with serum albumin forms dihydropyridinium, whose disproportionation gives rise to free radicals, and the free radicals induce the polymerization of HEMA.
首次提出Gluma的脱敏机理为:当Gluma涂在过敏的牙本质上时,首先戊二醛交联牙本质液中的血清蛋白并产生沉淀;同时戊二醛与血清蛋白的反应产生二氢吡啶盐,它发生歧化反应,歧化过程中会有自由基产生,从而引发HEMA 聚合,生成另外一部分沉淀,这两部分沉淀共同堵住牙本质小管,起到了脱敏作用。

Tetrachloroterephthalic acid was prepared by chlorinating terephthalic acid, oleumsolvent and iodine catalyst. Tetrachloroterephthalic acid was acylated by sulphurous oxychloride in the presence of DMF to form tetrachloroterephthaloyl chloride. The acyl chloride product was fluorinated by potassium fluoride and esterified by methanol to synthesize dimethyl tetrafluoroterephthalate. The ester was reduced with potassium borohydride and lithium chloride to give tetrafluoroterephthalyl alcohol. The above product was bromated in the hydrobromic acid to obtain 4-bromomethyl-2,3,5,6-tetrafluoro-benzene methanol. 4-Methyl-2,3,5,-6-tetrafluorobenzene ethanol was obtained by reducing the bromide with magnesium. In the exist of DCC and DMAP, tefluthrin was got by the condensation reaction between 4-methyl-2,3,5,6-tetrafluoro-benzene methanol and-(1RS,3RS)- 3-(2- chloro-3,3,3-trifluoro-1-propenyl)-2,2-dimethyl cycolpropanecar-boxylate acid.
