Total Phenolic Content and Antioxidant and Antibacterial Activities of Pereskia bleo

Advances in Pharmacological Sciences, 2019
Different solvent extracts of Pereskia bleo leaves were evaluated for total phenolic content (TPC) and antioxidant activities based on the Folin–Ciocalteu test and DPPH scavenging activities. The antibacterial activities against four bacteria, namely, Gram-positive bacteria: Streptococcus pyogenes ATCC 19615 (SP) and Staphylococcus aureus ATCC 29737 ...

High‐Modulus Skeleton‐Reinforced PDMS Microstamps for Precision Transfer Printing of Microscale Devices

Advanced Functional Materials, EarlyView.
Elastomeric micropillars bend under contact loading, sliding microscale devices out of alignment during transfer printing. A hybrid PDMS stamp embeds a high‐modulus skeleton within each pillar while retaining a compliant contact surface. The reinforcement confines pillar deformation, suppressing interfacial sliding and preserving array registration on ...

Hemocompatible Glycogen‐Tissue Plasminogen Activator Complexes for Enhanced Blood Clot Dissolution

Advanced Healthcare Materials, EarlyView.
Glycogen–heparin‐cRGD nanoparticles enable targeted delivery of tissue plasminogen activator (tPA) to thrombi through activated platelet recognition. The hemocompatible hybrids minimize interactions with blood and immune cells while retaining enzymatic biodegradability.
