Studies on interaction between Vitamin B12 and human serum albumin

The binding reaction between Vitamin B12 (B12, cyanocobalamin) and human serum albumin (HSA) was investigated by fluorescence quenching, UV–vis absorption and circular dichroism (CD) spectroscopy. Under simulative physiological conditions, fluorescence quenching data revealed that the quenching constants (K_sv) are 3.99 × 10⁴, 4.33 × 10⁴, 4.76 × 10⁴ and 5.16 × 10⁴ M⁻¹ at 292, 298, 304 and 310 K, respectively. The number of binding sites, n is almost constant around 1.0. On the basis of the results of fluorescence quenching the mechanism of the interaction of B12 with HSA has been found to be a dynamic quenching procedure. Thermodynamic parameters ΔH^Θ = −13.38 kJ mol⁻¹, ΔS^Θ = 66.73 J mol⁻¹ K⁻¹ were calculated based on the binding constant. These suggested that the binding reaction was enthalpy and entropy driven, and the electrostatic interaction played major role in stabilizing the reversible complex. The binding distance r = 5.5 nm between HSA and B12 was obtained according to Förster theory of energy transfer. The effect of B12 on the conformation of HSA was analyzed by synchronous fluorescence and CD spectroscopy. Synchronous spectra indicated that the polarity around the tryptophan (Trp214) residues of HSA was decreased and its hydrophobicity was increased; however, the α-helix content of the protein was predominant in the secondary structure but the CD spectra indicated that B12 induced minor conformational changes of HSA.     

醋酸艾塞那肽在Wistar大鼠体内的药物代谢动力学研究

研究醋酸艾塞那肽（exendin-4）在Wistar大鼠体内的药物代谢动力学，组织分布以及排泄特征。IODOGEN（四氯二苯基苷脲）法制备^125I-exendin-4，大鼠皮下或静脉注射，^125I-exendin-4，以放射性核素示踪动力法检测血液中的药物浓度，由非房室模型评价药物动力学参数。同时研究了大鼠皮下注射^125I-exendin-4后的组织分布和排泄。大鼠皮下注射^125I-exendin-4后Tmax和t1/2分别是（0．25±0．02）h和（1．28±0．14）h，绝对生物利用度为（65．5±10．2）％；^125I-exendin-4的分布快速而广泛，其中以肾脏中最高，而在脑组织中只有微量^125I-exendin-4；^125I-exendin-4主要随尿液排泄。实验结果与国外公布的实验数据基本一致。醋酸艾塞那肽在大鼠中的药物代谢动力学参数为临床试验提供了科学依据。

Edible safety requirements and assessment standards for agricultural genetically modified organisms.

This paper describes the background, principles, concepts and methods of framing the technical regulation for edible safety requirement and assessment of agricultural genetically modified organisms (agri-GMOs) for Shenzhen Special Economic Zone in the People's Republic of China. It provides a set of systematic criteria for edible safety requirements and the assessment process for agri-GMOs. First, focusing on the degree of risk and impact of different agri-GMOs, we developed hazard grades for toxicity, allergenicity, anti-nutrition effects, and unintended effects and standards for the impact type of genetic manipulation. Second, for assessing edible safety, we developed indexes and standards for different hazard grades of recipient organisms, for the influence of types of genetic manipulation and hazard grades of agri-GMOs. To evaluate the applicability of these criteria and their congruency with other safety assessment systems for GMOs applied by related organizations all over the world, we selected some agri-GMOs (soybean, maize, potato, capsicum and yeast) as cases to put through our new assessment system, and compared our results with the previous assessments. It turned out that the result of each of the cases was congruent with the original assessment.
