https://www.selleckchem.com/products/Aminocaproic-acid(Amicar).html Diabetic foot ulcer (DFU) is a common high-risk complication in patients with diabetes mellitus, but current drugs and therapies in management of this disease cannot meet the urgent clinical needs. In this study, a snail glycosaminoglycan (SGAG) from the cultured China white jade snail was purified and structurally clarified. This snail glycosaminoglycan is a regular sulfated polysaccharide, composed of iduronic acid (IdoA) and N-acetyl-glucosamine (GlcNAc) with the repeating sequence of →4)-α-GlcNAc (1→4)-α-IdoA2S (1→. The biological assays showed that SGAG had no anticoagulant activity for lacking speciﬁc heparin pentasaccharide sequence. The pharmacological experiments suggested that SGAG markedly accelerated the healing of full-thickness wounds in diabetic mice skin. Histologic and immunohistochemical analysis revealed that SGAG treatment alleviated the inflammation and dermal edema, and promoted angiogenesis. This is the first report applying the snail glycosaminoglycan to favor diabetic wound healing.Two high amylose (HAM) inbred lines with apparent amylose contents of 55 % and 62 %, respectively, were selected to explore the relationship between molecular structure and gene expression of starch-synthase involved enzymes. GPC analysis of debranched starches showed that the HAM starches (HAMSs) had shorter amylose chains and longer amylopectin chains than normal maize starch (NMS). FACE analysis showed that these HAMSs had a higher content of amylopectin chains of DP > 21. Quantitative Real-Time PCR analysis showed that the HAM lines had specifically low expression of the starch branching enzyme IIb (SBEIIb), and the starch synthase IIIa (SSIIIa) homologue, and high expression of the isoamylase 2 (ISA2), potentially suppressing the generation of amylopectin molecules through deficient branching and excessive debranching process, thereby increasing the relative amylose content. A high expression
