Nano artificial periosteum PLGA/MgO/Quercetin accelerates repair of bone defects through promoting osteogenic − angiogenic coupling effect via Wnt/ β-catenin pathway

Materials Today Bio, 2022
Bone nonunion or delayed union, caused by stripping or injuring of periosteum, is the most common sequelae of segmental bone defects. The preservation of periosteum, or the use of periosteal grafts, can significantly improve the integration of bone graft,

Identifying and Manipulating Giant Vesicles: Review of Recent Approaches

Micromachines, 2022
Giant vesicles (GVs) are closed bilayer membranes that primarily comprise amphiphiles with diameters of more than 1 μm. Compared with regular vesicles (several tens of nanometers in size), GVs are of greater scientific interest as model cell membranes ...

Molecularly Engineered Self-Assembling Membranes for Cell-Mediated Degradation [PDF]

, 2015
The use of peptide engineering to develop self-assembling membranes that are responsive to cellular enzyme activities is reported. The membranes are obtained by combining hyaluronan (HA) and a rationally designed peptide amphiphile (PA) containing a ...

Modulation of mitochondrial ion transport by inorganic polyphosphate - essential role in mitochondrial permeability transition pore [PDF]

, 2017
Inorganic polyphosphate (polyP) is a biopolymer of phosphoanhydride-linked orthophosphate residues. PolyP is involved in multiple cellular processes including mitochondrial metabolism and cell death. We used artificial membranes and isolated mitochondria
