Binding of Sodium Cholate In Vitro by Cationic Microfibrillated Cellulose
Bibliographic record
Abstract
In this work, a series of cationic microfibrillated cellulose (CMFC) were prepared by introducing quaternary amine groups, and the sorption of a model compound for bile salts, sodium cholate, in vitro was determined. Various variables, contact time, initial concentration of sodium cholate, and the presence of salts, were investigated. Experimental results showed that the in vitro binding of sodium cholate of the CMFC was 57.95 mg/g, which was about 70% lower than that of cholestyramine. The isotherm data were analyzed according to Langmuir, Freundlich, and Tempkin models. Characteristic parameters of each model were determined. Results also showed that the Langmuir isotherm performed the best correlation for the sorption of sodium cholate onto the CMFC, and the maximum capacity, Q max was 416.67 mg of sodium cholate per gram of CMFC. The sorption kinetics underwent a pseudo-second-order equation, suggesting a chemisorptions mechanism. Additionally, the presence of salts in the reaction system greatly prevented the CMFC sorption toward cholate, implying the interaction between sodium cholate and CMFC was electrostatic in nature. All these results support the great potential for using the CMFC as a sorbent to decrease cholesterol.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
