Study on the interaction between protein and Eu(III)–chlorotetracycline complex and the determination of protein using the ﬂuorimetric method

Luminescence (2004)

Shufang Liu Jinghe Yang Xia Wu Fei Wang Feng Wang

Abstract Chlorotetracycline (CTC) can react with europium ions Eu 3+ , and the complex emits the intrinsic ﬂuorescence of Eu 3+ . The intensity is greatly enhanced by proteins and this forms the basis of a new ﬂuorimetric method for determination of protein. Further research indicates that under optimum conditions, the enhanced intensity of ﬂuorescence is in proportion to the concentration of proteins, in the range 2.0 × 10 −7 –1.0 × 10 −5 g/mL for bovine serum albumin (BSA) (linear equation, I f = 34.35933 + 11.54467 × 10 6 C)( r = 0.99895) and 8.0 × 10 −7 –1.0 × 10 −5 g/mL for human serum albumin (HSA) (linear equation, I f = 76.58881 + 5.3569 × 10 6 C) ( r = 0.99283). Detection limits (S/N = 3) were 8.9 × 10 −9 g/mL for BSA and 3.3 × 10 −8 g/mL for HSA. In an assay for BSA in calf serum, this method gave a value close to that determined by the UV spectrophotometric method. Copyright © 2004 John Wiley & Sons, Ltd.

Progresses of Derivatization Techniques for Analyses of Carbohydrates

Analytical Letters (2003)

Xibao Gao Jinghe Yang Fang Huang Xia Wu Lei Li

Abstract Carbohydrates, one of the most important bioactive materials and information-carrying molecules, play important roles in physiological and pathological processes. Unfortunately the direct chemical analysis of carbohydrates is difficult because of their characteristics. Recently, the investigations of carbohydrates made a great development because of considerable progresses in the derivatization techniques of carbohydrates. This article summarized several derivatization techniques, including the derivatization reactions with amines and amine-like compounds, derivatizations of amino sugars, derivatizations with reducibility of carbohydrates, derivatizations by chemiluminescences and enzyme reactions, derivatization of conversion to furfurals, derivatization reactions with boronic acid derivatives. Their advantages, problems, and applications are discussed. About 95 references are cited.

Jervell and Lange-Nielsen Syndrome due to a Novel Compound Heterozygous KCNQ1 Mutation in a Chinese Family

Neural Plasticity (2020)

Yue Qiu Sen Chen Xia Wu Wenjuan Zhang Wen Xie

Jervell and Lange-Nielsen syndrome (JLNS) is a rare but severe autosomal recessive disease characterized by profound congenital deafness and a prolonged QTc interval (greater than 500 milliseconds) in the ECG waveforms. The prevalence of JLNS is about 1/1000000 to 1/200000 around the world. However, exceed 25% of JLNS patients suffered sudden cardiac death with kinds of triggers containing anesthesia. Approximately 90% of JLNS cases are caused by KCNQ1 gene mutations. Here, using next-generation sequencing (NGS), we identified a compound heterozygosity for two mutations c.1741A>T (novel) and c.477+5G>A (known) in KCNQ1 gene as the possible pathogenic cause of JLNS, which suggested a high risk of cardiac events in a deaf child. The hearing of this patient improved significantly with the help of cochlear implantation (CI). But life-threatening arrhythmias occurred with a trigger of anesthesia after the end of the CI surgery. Our findings extend the KCNQ1 gene mutation spectrum and contribute to the management of deaf children diagnosed with JLNS for otolaryngologists (especially cochlear implant teams).

Study on a Fluorometric Method for the Determination of Protein in Serum Using Quercetin‐Lanthanum (III)‐Sodium Dodecyl Benzene Sulfonate‐Protein System

Analytical Letters (2006)

Zhen Jia Jinghe Yang Xia Wu Fei Wang Shufang Liu

Abstract It was found that the fluorescence intensity of lanthanum (III) (La3+)‐quercetin (Qu) complex is greatly enhanced by proteins in the presence of sodium dodecyl benzene sulfonate (SDBS). Based on this finding, a new fluorimetric method for the determination of proteins was developed. Under optimum conditions, the enhanced intensity of fluorescence is in proportion to the concentration of proteins in the range of 2.5×10−8 to 1.0×10−5 g/mL for bovine serum albumin (BSA), 5.0×10−8 to 1.5×10−5 g/mL for human serum albumin (HSA), and 1.0×10−7 to 1.5×10−5 g/mL for egg albumin (EA). Their detection limits (S/N=3) are 5.0×10−9 g/mL, 7.0×10−9 g/mL, and 2.1×10−8 g/mL, respectively. The interaction mechanism was also studied.
