The application of a three-column internal fixation system with anatomical locking plates on comminuted fractures of the tibial plateau.

Aim: The purpose of this study was to describe the operative procedures and clinical outcomes of a new three-column internal fixation system with anatomical locking plates on the tibial plateau to treat complex three-column fractures of the tibial plateau.

Methods: From June 2011 to May 2015, 14 patients with complex three-column fractures of the tibial plateau were treated with reduction and internal fixation through an anterolateral approach combined with a posteromedial approach. The patients were randomly divided into two groups: a control group which included seven cases using common locking plates, and an experimental group which included seven cases with a new three-column internal fixation system with anatomical locking plates.

Improving gene targeting efficiency on pig IGF2 mediated by ZFNs and CRISPR/Cas9 by using SSA reporter system.

IGF2 (Insulin-like growth factor 2) is a major growth factor affecting porcine fetal and postnatal development. We propose that the precise modification of IGF2 gene of Chinese indigenous pig breed--Lantang pig by genome editing technology could reduce its backfat thickness, and increase its lean meat content. Here, we tested the genome editing activities of zinc finger nucleases (ZFNs) and CRISPR/Cas9 system on IGF2 gene in the Lantang porcine fetal fibroblasts (PEF).

[Infrared spectroscopy investigation on conformational change of silk fiber induced by gaseous organic acids existing in museum].

Study on the impact of pollutants on cultural materials in storing or displaying micro-environment in museum is considered as very important for the preservation of cultural relics and its aging prevention. This paper applied the Fourier transform infrared (attenuated total reflection) technique to assess silk structural changes under volatile organic acids (formic acid/acetic acid), which usually come from decorative materials emission and commonly exist in the surface or around cultural materials. The focus of this work was on investigating the changes of peptide bond in the area of amide I-amide III, as well as the peptide chains (GlyAla), characteristic region.
