Active membrane recycling induced morphology changes in vesicles

Frontiers in Physics, 2022
Membranes of organelles in the intracellular trafficking pathway continuously undergo recycling through fission and fusion processes. The effect of these recycling processes on the large-scale morphology of organelles is not well understood.

Membrane curvature induces cardiolipin sorting [PDF]

Communications Biology, 2019
AbstractCardiolipin is a cone-shaped lipid predominantly localized in curved membrane sites of bacteria and in the mitochondrial cristae. This specific localization has been argued to be geometry-driven, since the CL’s conical shape relaxes curvature frustration. Although previous evidence suggests a coupling between CL concentration and membrane shape

A Review of Acrylic Bone Cement in the Masquelet Technique: From Temporary Spacer to a Bioactive Modulator of the Induced Membrane

Sci
Critical-sized bone defects remain a major reconstructive challenge, and the Masquelet technique has become an important option in traumatic, infectious, and post-resection settings. This review examines the role of acrylic bone cement in this technique,

The induced membrane technique for bone defects: Basic science, clinical evidence, and technical tips

OTA International, 2021
. The clinical management of large bone defects continues to be a difficult clinical problem to manage for treating surgeons. The induced membrane technique is a commonly employed strategy to manage these complex injuries and achieve bone union.

Cargo induces retromer-mediated membrane remodeling on membranes

Molecular Biology of the Cell, 2018
Endosomes serve as a central sorting station of lipids and proteins that arrive via vesicular carrier from the plasma membrane and the Golgi complex. At the endosome, retromer complexes sort selected receptors and membrane proteins into tubules or vesicles that bud off the endosome. The mature endosome finally fuses with the lysosome.

The Impact of Defect Size on Bone Healing in Critical-Size Bone Defects Investigated on a Rat Femur Defect Model Comparing Two Treatment Methods

Bioengineering
Critical-size bone defects up to 25 cm can be treated successfully using the induced membrane technique established by Masquelet. To shorten this procedure, human acellular dermis (HAD) has had success in replacing this membrane in rat models. The aim of

Stress fracture after implant removal from the tibia reconstructed by the induced membrane technique: A case report

Trauma Case Reports, 2022
Background: The induced membrane technique promotes vascularization and corticalization of the grafted bone and has become one of the mainstays in treatment of segmental bone defects.

Membrane Buckling Induced by Curved Filaments

Physical Review Letters, 2009
We present a novel buckling instability relevant to membrane budding in eukaryotic cells. In this mechanism, curved filaments bind to a lipid bilayer without changing its intrinsic curvature. As more and more filaments adsorb, newly added ones are more and more strained, which destabilizes the flat membrane.

Influence of the Immune Microenvironment Provided by Implanted Biomaterials on the Biological Properties of Masquelet-Induced Membranes in Rats: Metakaolin as an Alternative Spacer

Biomedicines, 2022
Macrophages play a key role in the inflammatory phase of wound repair and foreign body reactions—two important processes in the Masquelet-induced membrane technique for extremity reconstruction.

Induced membrane technique in the treatment of infectious bone defect: A clinical analysis.

Orthopaedics & Traumatology: Surgery & Research, 2019
BACKGROUND At present, it is still a challenge for repairing a wide range of bone defect caused by various reasons. We aimed to investigate the effect of induced membrane technique in the treatment of infectious bone defect.
