Effects of combined chickpea protein isolate and chitosan on the improvement of technological quality in phosphate-free pork meat emulsions: Its relation to modifications on protein thermal and structural properties.

The effects of combined chickpea protein isolate (CPI, 1%, w/w) and chitosan (CHI, 1%, w/w) on the technological, thermal, and structural properties of phosphate-free pork meat emulsions (PPMEs) were investigated. The results showed that CPI + CHI significantly improved the emulsion stability (P < 0.05), synergistically elevated the hardness and chewiness, and did not negatively impact the color attributes, which endowed the PPMEs with similar or even better technological performances compared to the high-phosphate control. These alterations were related to the reduced myosin enthalpy values, the rearrangement of free water into immobilized water, the synergistic reduction in α-helical structure and increase in ß-sheet structure, the increased trans-gauche-trans SS conformation intensity of the Raman bands, and the formation of interactive protein gel networks where small-sized fat particles were evenly dispersed in the protein matrix. Therefore, combined CPI and CHI shows promise as a phosphate replacer for meat products.

[Treatment of anterior dislocation of sternoclavicular joint with Kirschner wire minimally invasive fixation].

OBJECTIVE: To investigate the safety and efficacy of close reduction and percutaneous needle fixation for the treatment of anterior dislocation of sternoclavicular joint. METHODS: A retrospective analysis was performed with 6 cases of anterior sternoclavicular dislocation by close reduction and percutaneous needle fixation with Kirschner wire treated from January 2001 to February 2009, including 5 males and 1 female aged from 19 to 45 with an average of 28.8 years old. Among the 6 cases, 4 were on right lateral and 2 were on left lateral. The time from injured to treatment was from 6 hours to 12 days (averaged 4.5 days). The clinical effects were evaluated according to Rockwood scoring and the complications were observed. RESULTS: All 6 patients were followed-up for 3 to 13 months (averaged 6 months). According to Rockwood scoring,the preoperative score was (7.00 +/- 0.89) points, postoperative score was (13.17 +/- 1.72) points; the results showed excellent in 5 cases and good in 1 case. No local infection, postoperative pain,recurrent dislocation,broken needle, and other complications were observed in this study. CONCLUSION: The treatment of anterior sternoclavicular joint dislocation with Kirschner wire minimally invasive fixation is an easy, reliable fixation with less complications.
