Abstract: A hydrogel tissue adhesive having decreased degradation time is described. The hydrogel tissue adhesive is formed by reacting an oxidized polysaccharide with a water-dispersible, multi-arm polyether amine in the presence of an oligomer additive, which promotes the degradation of the hydrogel. The hydrogel may be useful as a tissue adhesive or sealant for medical applications, such as a hemostat sealant or to prevent undesired tissue-to-tissue adhesions resulting from trauma or surgery.

Abstract: A mill dried microcrystalline cellulose (MCC) is obtained in a process comprising the steps of a) providing MCC having a moisture content of from 20 to 75 percent, based on the total weight of the moist MCC; and b) mill-drying the moist MCC in a single device capable of milling and drying in combination. The process can provide mill-dried microcrystalline cellulose having similar particle size distribution (LEFI, DIFI and EQPC) and moisture content as the corresponding spray-dried microcrystalline cellulose. The process can provide mill-dried microcrystalline cellulose having a higher tapped/untapped bulk density and/or a lower Carr index, while keeping a similar moisture content, as the corresponding spray-dried microcrystalline cellulose.
