Purpose: To study the mechanical and dynamic swelling properties of grewia gum, evaluate its compression behaviour and determine the effect of drying methods on its properties. Methods: Compacts (500 mg) of both freeze-dried and air-dried grewia gum were separately prepared by compression on a potassium bromide (KBr) press at different pressures and subjected to Heckel analysis. Swelling studie...

background: since the treatments of long tracheal leisions are associated with some limitations, tissue enginered trachea is considered as an alternative option. this study aimed at preparing a composite scaffold, based on natural and synthetic materials for tracheal tissue engineering. methods: nine chitosan silk-based scaffolds were fabricated using three freezing rates (0.5, 1, and 2°c/min) ...
