Salivary Protein and Electrolyte Profiles during Primary Teeth Eruption: A Cross-Sectional Study.

This study aimed to assess the qualitative changes in the saliva during the process of primary teeth eruption. This cross-sectional study was conducted on 147 children from 2 to 48 months, of which 49 were in group A (no erupted primary teeth), 53 were in group B (at least one active erupting primary tooth), and 45 were in group C (eruption of all 20 primary teeth was completed). Salivary proteins were evaluated by sodium dodecyl sulfate electrophoresis with polyacrylamide gel, while the concentrations of salivary sodium, potassium, chloride, and calcium ions were evaluated by ion selective electrodes.

Optimization of Buffer Additives for Efficient Recovery of hGM-CSF from Inclusion Bodies Using Response Surface Methodology.

Overexpression of human granulocyte-macrophage colony-stimulating factor (hGM-CSF) by leads to formation of insoluble and inactive proteins, inclusion bodies. The aim of this study was to improve recovery of biologically active hGM-CSF from inclusion bodies. The effect of types, concentrations and pHs of denaturing agents and addition of reducing agents on the yield of inclusion bodies solubilization was evaluated.
