Hydrothermal Synthesis of Molybdenum Disulfide Quantum Dots for Highly Sensitive Detection of Iron Ions in Protein Succinate Oral Solution.

In this paper, a molybdenum disulfide fluorescent probe with an Fe fluorescent system was first synthesized by the hydrothermal method for the detection of iron ion concentration in oral solution of protein succinate. It was characterized by infrared, fluorescence, X-ray photoelectron spectroscopy, scanning electron microscopy, and transmission electron microscopy. The probes were found to have good stability, photobleaching, and storage stability.

Expression, purification and characterization of a novel recombinant SVTLE, r-agkihpin-2, from Gloydius halys Pallas venom gland in Escherichia coli.

In our previous work, a thrombin-like enzyme (TLE), agkihpin, was successfully isolated, purified, cloned and named from the venom of Gloydius halys Pallas, having fibrinolytic, fibrinogenolytic and thrombosis-reduced activities, attenuating migration of liver cancer cell, and without bleeding risk. To explore the possibility of agkihpin as a thrombolytic and/or anti-metastasis agent in the future, in this study recombinant agkihpin was expressed and purified in Escherichia coli, and its biological activities investigated. Thus, r-agkihpin-2 was successfully expressed and purified and confirmed by Western blot and peptide mass fingerprinting.

[Haplotype analysis for mucocutaneous venous malformations in a Chinese Han ethnic family].

A Chinese Han ethnic family with mucocutaneous venous malformations (VMCM) was investigated. This family has autosomal dominantly inherited VMCM in five generations, and the offspring has a 50% risk of this inherited disorder. Affected individuals have small, spongy, and multiple vascular lesions, which often locate in the skin, oral mucosa, and upper and lower extremities.
