In this work, we describe the synthesis and characterization of variants of poly(diol fumarate) and poly(diol fumarate-co-succinate). Through a Fischer esterification, α,ω-diols and dicarboxylic acids were polymerized to form aliphatic polyester comacromers. Because of the carbon-carbon double bond of fumaric

Long carbon chain alkanediols are used in the production of poly(3-hydroxybutyrate-co-4-hydroxybutyrate) [P(3HB-co-4HB)], however these substrates possess high toxicity towards bacterial cells. This study demonstrated the effective utilisation of a long carbon chain alkanediol, namely 1,8-octanediol, to enhance the yield and

Bone-patellar tendon-bone (BPTB) autografts are the gold standard for anterior cruciate ligament (ACL) reconstruction because the bony ends allow for superior healing and anchoring through bone-to-bone regeneration. However, the disadvantages of BPTB grafts include donor site morbidity and patellar rupture.
