The present study investigated in vitro the effects of sulphated heterorhamnan (Go3), iota-/nucarrageenans (G3d and EHW-I) and arabinogalactan (ARAGAL) polysaccharides on macrophage activation and inhibition of intracellular amastigotes of Leishmania (L.) amazonensis. All the sulphated polysaccharides (Go3, G3d and EHW-I) promoted increased nitric oxide production varying from 71 to 110%. The leishmanicidal activity of all compounds was compared to the inhibition effect of Meglumine Antimoniate at 300 mu g/mL (similar to 79%), used as positive control. Inhibition of Leishmania (L.) amazonensis growth was 55% with 5 mu g/mL of Go3, 50% and 98% to G3d and EHW-I, respectively at 10 mu g/mL, and 88% with 10 mu g/mL of ARAGAL. The superoxide anion scavenging activity for the sulphated polysaccharides varied from approximately 30-55% at 10 mu g/mL. In conclusion, the results of the present study indicate the promising potential of these polysaccharides for the development of new alternative therapeutic agents against leishrnaniasis.

Effects of aging and diabetes on the deformation mechanisms and molecular structural characteristics of collagen fibrils under daily activity

Wei-Han Hui, Yen-Lin Chen, Shu-Wei Chang

Summary: Crosslinking affects the mechanical behavior and tissue metabolism of collagen-based tissues. Aging and diabetes alter the crosslinking type and density, thus changing tissue properties. High-connectivity enzymatic crosslinking and advanced-glycation end-products result in uniform deformation under daily activity, while low-connectivity enzymatic crosslinking does not. High-connectivity model displays more sliding, while AGEs induce instability in structures near the binding sites.
