Study of antioxidant properties of sulfomethylated lignin and its application in pesticide dispersants.

The utilization of lignin as a dispersant and protective agent for pesticide is a promising strategy for its high-value application, however, its use is limited by the poor solubility of lignin. In this study, the solubility and antioxidant performance of lignin were enhanced by treating it with Fenton's reagent and sulfomethylation reaction. The product has a sulfur content of up to 6.

Drinking Water Supplemented with Acidifiers Improves the Growth Performance of Weaned Pigs and Potentially Regulates Antioxidant Capacity, Immunity, and Gastrointestinal Microbiota Diversity.

This study evaluated the potential effects of adding acidifiers to the drinking water on the growth performance, complete blood count, antioxidant indicators, and diversity of gastrointestinal microbiota for weaned pigs. A total of 400 weaned pigs were randomly divided into four treatments. Pigs were fed the same basal diet and given either water (no acidifier was added, control) or water plus blends of different formulas of acidifiers (acidifier A1, A2, or A3) for 35 days.

[Surgical treatment of calcaneus fracture involving posterior subtalar articular facet].

Objective: To investigate the methods of reduction and stable fixation for the treatment of calcaneus fracture involving posterior subtalar articular facet.

Methods: From September 2004 to September 2008, 31 cases(38 feet) of calcaneus fracture involving posterior subtalar articular facet were treated with open reduction and plate fixation through L incision. There were 24 males and 7 females, with an average age of 39.
