CdSe/CdS quantum dots (QDs) capped with L-cysteine can provide an effective platform for the interactions with bovine serum albumin (BSA). In this study, absorption and fluorescence (FL) spectroscopy were used to study the binding reactions of QDs with BSA, respectively. The binding constant (≈10(4) M(-1)) from FL quenching method matches well with that(More)
As a novel immunosuppressant, FTY720 (2-amino-2-(2-[4-octylphenyl] ethyl)-1, 3-propanediol hydrochloride) has been used to prevent the allograft rejection in organ transplantation. FTY720 can prolong markedly survival of the allograft by inducing apoptosis of reactive lymphocytes and by redirecting the homing of lymphocytes. However, as the archetype of a(More)
A CMS line specific mtDNA band TA1 was isolated by comparing the mtDNAs of CMS line and maintainer line using AFLP technique. The Northern blot analysis of the TA1 mtDNA fragment show that it transcripts only one RNA molecular each in CMS line, maintain line and the first filial generation, but the RNA moleculars are different among each other.

The reactions between Laccase (extracted from China lacquer of Rhus vernicifera) and various substrates (3,4-Dihydroxybenzaldehyde, Guaiacol, Pyrogallol, Gallic acid) have been studied using LKB-2107 batch microcalorimetry system. Based on calorimetry, a new method has been proposed. Laccase activity and the Michaelis constant K(m) have been determined(More)
OBJECTIVE Members of the tripartite motif (TRIM) protein family contain a highly conserved N-terminal really interesting new gene (RING) domain that is involved in regulating transcriptional factors and tumor suppressors. In this study, the effects of TRIM59 expression on tumor growth were investigated in prostate cancer. MATERIALS AND METHODS The(More)
The thermogenesis curves of the germination of different rice and tree seeds were determined and studied by using a newly constructed microcalorimeter. The thermogenesis curves of the germination of the seeds demonstrate the existence of physiological triphasic patterns, which include imbibition, activation and growth stages in the germination process. The(More)
The thermodynamic and kinetic behaviors of energy release of mitochondria isolated from rice (Oryza sative L.) were studied by using a LKB 2277 Bioactivity Monitor under different conditions. The thermogenesis curves of energy release of the rice mitochondria (which had been kept at 0-3 degrees C for 15 h and 40 day before the determination) were determined(More)
