Bioresorbable Osmotic Pump for Long–term Contraception
… market are mostly limited to non-bioresorbable matrix-diffusion systems. These Fickian diffusion-based systems raise problems like inconstant release rates that compromise their long-term efficacy, the requirement of surgical removal, and a long pharmacokinetic tail that delays the user’s return …

Development of an Injectable Hydrogel Platform to Capture and Eradicate Glioblastoma Cells with Chemical and Physical Stimuli
… of GBM cells and GSCs from the extracellular matrix and into the synthetic hydrogel with ameboid migration and myosin IIA activation. This injectable hydrogel also demonstrated direct therapeutic benefits by passively eradicating entrapped GBM cells through matrix diffusion limitations as well …

High-temperature metamorphism in the western Namaqua-Natal Metamorphic Province (South Africa): implications for low-pressure granulite terranes
… isolating the porphyroblasts from the matrix. Diffusion of Fe + Mg along respective gradients of µFe and µMg with simultaneous immobility of Al + Si led to the breakdown of andalusite to symplectites of cordierite + spinel during near-isobaric heating to peak conditions. Monomineralic …

The Mechanism of Action of Hyaluronan Therapy as a Treatment for Osteoarthritis and the Assessment of Osteoarthritic Articular Cartilage Using Ultrasound
… of its movement through the extracellular matrix. These experiments show that HA can penetrate the cartilage matrix despite its size, entering the tissue within one hour. This finding challenges the traditional explanation of the treatment known as <i>viscosupplementation</i>, which assumes …
