AIM To study the interaction between strychnine and bovine serum albumin. METHODS Fluorescence spectroscopy and ultraviolet spectroscopy were used. RESULTS The static quenching and the non-radiation energy transfer are the two main reasons to leading the fluorescence quenching of BSA. The apparent combining constants (K(A)) between strychnine and BSA(More)
Through the flow injection analysis experiments, we discovered that an unsaturated complex of Cu(II) and polyamines (spermine, spermidine, putrescine) had a strongly catalytic effect on luminol-H(2)O(2) chemiluminescence (CL) reaction, and that the CL intensity is proportional to the concentrations of polyamines. Based on the automatic formation of an(More)
OBJECTIVE To explore the characteristics of psychotic patients with suicide attempts in a Chinese rural community. METHOD An epidemiological investigation of psychotic patients with suicide attempts among 123,572 population (over 15 years of age) was conducted in Xinjin County, Chengdu. RESULTS The rate of suicide attempts was found to be 8.17% among(More)
A novel dumbbell-shaped ZnO photocatalyst was successfully synthesized by microwave heating in the present study. The prepared ZnO photocatalysts were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and UV-Vis absorption spectrum (UV-Vis). The results indicated that the prepared ZnO photocatalyst shows a united dumbbell shape(More)
The binding reaction between daidzein and human serum albumin (HAS) was studied by fluorescence quenching spectra, synchronous fluorescence spectra and ultraviolet spectra. The results indicated that daidzein led to the quenching of the intrinsic fluorescence of HSA. The fluorescence quenching mechanism between daidzein and HSA was mainly static quenching,(More)
The binding reaction of fangchinoline with bovine serum albumin was studied at different temperatures by fluorescence quenching spectra, synchronous fluorescence spectra and ultra-violet spectra. It was shown that fangchinoline has a strong ability of quenching the fluorescence of BSA. The Stern-Volmer curve of the fluorescence quenching of BSA by(More)
The interaction of quercetin and bovine serum albumin (BSA) was investigated using fluorescence spectroscopy (FS) and ultraviolet spectroscopy (UV). The apparent binding constants (KA) between quercetin and BSA were 2.8 x 10(8) (26 degrees C) and 3.1 x 10(8) (36 degrees C), and the binding sites (n) were 1.7+/-0.02. According to the Förster theory of(More)
The interaction of genistein and human serum albumin (HSA) was investigated by fluorescence quenching spectra, synchronous fluorescence spectra and ultra-violet absorption spectra. The results showed that the quenching mechanism of the intrinsic fluorescence of HSA by genistein is due to the formation of genistein-HSA complex, resulting in a static(More)
This study evaluated the characteristics of suicidal behavior (suicide attempt or suicidal ideation) among 230 consecutively admitted inpatients with schizophrenia and mood disorders in a university hospital in China. The rate of lifetime suicidal behavior was found to be significantly higher in patients with mood disorders (62.4%) than in patients with(More)
The interaction between luteolin and human serum albumin (HSA) was studied by using fluorescence quenching spectra, synchronous fluorescence spectra and ultra-violet spectra. The results showed that luteolin had a strong ability to quench the fluorescence of HAS The Stern-Volmer curve of the fluorescence quenching of HSA by luteolin indicated that the(More)
