Bioactive 3D-Shaped Wound Dressings Synthesized from Bacterial Cellulose: Effect on Cell Adhesion of Polyvinyl Alcohol Integrated In Situ

We investigated wound dressing composites comprising fibrils of bacterial cellulose (BC) grown by fermentation in Food Serving Pails/Buckets the presence of polyvinyl alcohol (PVA) followed by physical crosslinking.The reference biointerface, neat BC, favoured adhesion of fibroblasts owing to size exclusion effects.Furthermore, it resisted migratio

Automatic Calibration of Process Noise Matrix and Measurement Noise Covariance for Multi-GNSS Precise Point Positioning

The Expectation-Maximization algorithm is adapted to the extended Kalman filter to multiple GNSS Precise Point Positioning (PPP), named EM-PPP.EM-PPP considers better the compatibility of multiple GNSS data processing and characteristics of receiver motion, targeting to calibrate the process noise matrix Qt and observation matrix Rt, having influen

The putative Notch ligand HyJagged is a transmembrane protein present in all cell types of adult Hydra and upregulated at the boundary between bud and parent

Abstract Background The Notch signalling pathway is conserved in pre-bilaterian animals.In the Cnidarian Hydra it is involved in interstitial stem cell differentiation and in boundary formation during budding.Experimental evidence suggests that in Hydra Notch is activated by presenilin through proteolytic cleavage at the S3 site as in all animals.H
