Article Synopsis
  • The study explores how the chain structures of random copolyesters affect their properties like biodegradability, mechanical strength, and thermal stability, while highlighting the difficulties in obtaining specific chain sequence information.
  • A new mathematical model using a probabilistic approach is presented to analyze the sequence length and distribution in different copolyesters, specifically examining poly(butylene adipate--terephthalate) and poly(butylene succinate--glycolic acid).
  • The findings indicate that adding hydroxyl acid units can lower sequence length without changing composition, improving degradation rates while keeping mechanical properties stable, especially significant for certain copolymer compositions.

In the past 40 years, the incidence of esophagogastric junction cancer has been gradually increasing worldwide. Currently, surgical resection remains the main radical treatment for early gastric cancer. Due to the rise of functional preservation surgery, proximal gastrectomy has become an alternative to total gastrectomy for surgeons in Japan and South Korea.
