A novel and convenient approach to chlorophins and bacteriophins has been developed through a degradation of nickel(II) 2,3,12,13-tetrabromo-5,10,15,20-tetraarylporphyrins by the anion of E-benzaldoxime. The UV-vis spectra of these chlorophins and bacteriophins are similar to those of metalated chlorin and bacteriochlorin systems but with more intense and… (More)
OBJECTIVE (1) To compare singleton and twin pregnancies with regard to changes in the Pulsatility Index (PI) of uterine arteries over the course of the pregnancy; (2) To examine the effect of the location of the placenta on the PI in the uterine arteries in twin pregnancies. METHODS We prospectively studied the PI of uterine arteries in 99 women with… (More)
AIM To investigate the effects of piperine, a major pungent alkaloid present in Piper nigrum and Piper longum, on the tumor growth and metastasis of mouse 4T1 mammary carcinoma in vitro and in vivo, and elucidate the underlying mechanisms. METHODS Growth of 4T1 cells was assessed using MTT assay. Apoptosis and cell cycle of 4T1 cells were evaluated with… (More)
The [1 + 2] cycloaddition reaction of 1-iodoalkynes with difluorocarbene, generated from the decomposition of FSO(2)CF(2)COOSiMe(3) in diglyme in the presence of 10 mol % NaF at 120 degrees C, gives 3,3-difluoro-1-iodocyclopropenes in good yields. These new iodides can be trifluoromethylated and functionalized via the Heck reaction. The unusual hydrolytic… (More)
OBJECTIVE To evaluate the overexpression of cyclin G1 in cervical intraepithelial neoplasia (CIN) and cervical carcinoma, and the correlation between cyclin G1 and high-risk human papilloma virus (HPV) infection. METHODS All of the specimens were obtained from the Department of Pathology of China-Japan Friendship Hospital from January 2000 to August 2004.… (More)
Treatment of C70 with cycloalkylaminomethylenebisphosphonates in the presence of NaH gave corresponding C70 dimers 1 in good yield, while the methanofullerenes, C70>CH(PO3Et2) (3) and C70>C(PO3Et2)2 (4) or C60>CH(PO3Et2) (5) and C60>C(PO3Et2)2 (6), were obtained, respectively, by the reaction of C70 or C60 with tetraethyl methylenediphosphonate in the… (More)
An unexpected, mild, efficient bromination ring-opening method has been developed for convenient synthesis of various novel biladienes or brominated porphyrins by controlling the amounts of NBS used.
OBJECTIVE To evaluate the clinical efficacy of flow-through hybridization and gene chip (HybriMax) on female low genital human papillomavirus (HPV) detection and to identify the most common HPV genotypes. METHODS Five hundred and ninety-one of 7520 women who received cervical cancer screening in China-Japan Friendship Hospital during Jun 2004 to May 2005… (More)
The CF(3) radical was generated from the reaction of S-(trifluoromethyl)diphenylsulfonium triflate with Na(2)S(2)O(4) or HOCH(2)SO(2)Na under suitable conditions without further reduction. Based on this, a method for the synthesis of α-trifluoromethylated ketones has been successfully developed.
