The CMC (DS = 0.7) was procured from Across Organics/Thermo Fischer (CAS 9004-32-4, Geel, Belgium) and AFT salt from Sigma-Aldrich (CAS:540-69-2, Sigma–Aldrich Co., St. Louis, MO, USA). Both materials were used without any purification process. To produce the CMC-AFT biopolymer electrolytes, 1 g of CMC was first dissolved in distilled water. Once the CMC was completely dissolved, varied amount (10–50 wt.%) of AFT was added into the CMC solution. The solution was left to stir for 24 h to ensure complete salt dissolution. Then, the CMC-AFT solution was cast into glass petri dishes for the drying process. The dried samples were then kept in desiccators to prevent contamination and moisture absorption before further characterization. Table 1 shows the CMC-AFT biopolymer electrolyte composition for each sample.

Eighty male C57BL/6 mice were purchased from the Experimental Animal Center of Guangzhou University of Chinese Medicine. Eight to ten weeks old mice were taken for the study. All mice after acclimatization were split into different groups of 30 mice each. High-fat diet (HFD) was given to create obese model to weigh more than the normal ones and normal diet (ND) was given to others [20 (link)] (Table 1 ). DIBP was dissolved in sodium carboxymethylcellulose (CMC-Na) (0.3%) (CAS#9004-32-4 ) (Sigma–Aldrich, St. Louis, MO, USA) at a concentration of 300 mg per kg (low), 500 mg per kg (medium), and 1000 mg per kg (high). The normal and obese groups were further divided into four sub-groups. One sub-group was control (0.3% CMC-Na) (oral gavage) (ND-C/HFD-C group), and the remaining groups were low (ND-L/HFD-L), medium (ND-M/HFD-M) and high (ND-H/HFD-H) DIBP concentrations for 10 weeks as mentioned earlier. Mice were euthanized by isoflurane and the Institutional Animal Care and Use Committee (IACUC) protocols were followed for the animals.Table 1

It is well known that, for practical applications, most of the SCMC intraperitoneal anti-adhesion and hemostasis medical devices were made with low viscosity SCMC. Therefore, low viscosity SCMC powder (CAS: 9004-32-4, viscosity: 100, degree of substitution: 0.81, sodium content: 7.4%, Lot No.: SLB × 2402) purchased from Sigma, Saint Louis, MO, USA was used in our work.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
