TL;DR: In this article, the authors found that the optimum temperature of SMIA-2 was 60oC and the optimum pH of the enzyme was found to be 8.0, a decrease of about 51%, 18% and 66% of its original activity was observed respectively.

TL;DR: It appears that the relative success of the citric acid application in periodontal reattachment procedures is realted to the fact that the acid causes exposure of collagen fibrils in the dentin matrix, thus providing a suitable nidus for splicing with new fibril during the healing process.
Abstract: The effect of topically applied citric acid on periodontally diseased root surfaces was evaluated using the scanning (SEM) and transmission (TEM) electron microscopes. Results with the SEM indicate that acid application had no effect on specimens that had not been root planed. After application to root planed surfaces, however, the acid priduced a fiber-like surface with frequent depressions. TEM observations showed that the acid application produced a four micron wide demineralized zone, which was characterized by exposed collagen fibrils. These fibrils seemed to be continuous between the mineralized and demineralized zones of the root.

TL;DR: In this article, the dissolution of CuO in HCl, H 2 SO 4, HNO 3 and citric acid solutions was investigated in a batch reactor employing parameters expected to affect the dissolution rate of copper such as stirring speed, temperature and acid concentration.

TL;DR: Five patients with uric acid nephrolithiasis showed different responses between sodium alkali and potassium alkali treatment, and all five patients had persistently low urinary pH and normouricosuria, and four had hyperuricemia.
