Background & Aims: Amniotic membrane persists for a long time after ocular transplantation (as corneal substitute) and can affect light transmission (transparency). The aim of this study was to evaluate the transparency of amniotic membrane after freeze-drying (lyophilization) and to compare the results with transparency of rabbit cornea. Methods: Transparency of rabbits’ corneas and fresh and ...
Hollow fiber membrane contactors have been applied in various industries e.g. chemistry, petroleum, biotechnology and medicine. They are also widely used in artificial organs e.g. artificial lung, kidney and liver as well as some pharmaceutical procedures such as separation and purification of biological materials. Intrinsic properties of hollow fiber membranes, such as high packing density and...
Introduction: Scaffold has therole of the extracellular matrix in regulating cell survival and it is an important component in tissue engineering techniques. One of the scaffolds that was used in this field, was PLLA (poly L-lactic acid) which was usually prepared by electro spinning method. The purpose of this study was to evaluate the biocompatibility of nano-porous PLLA membrane on prolifera...
Precision Drug Delivery In article number 2206989, Yu Tao, Mingqiang Li, Xuesi Chen, and co-workers report a membrane-fusogenic liposome to precisely convey two glycan-engineering drugs onto the cell membrane into cytoplasm for physical modification of natural-killer-cell-activating glycans biological inhibition immunosuppressing glycans, respectively, thus sufficiently arousing natural killer ...
Background: Tissue engineering has been investigated as a potential method for healing traumatized tissues. Biomaterials are material devices or implants used to repair or replace native body tissues and organs. The present study was conducted to evaluate the effects of decontamination methods on biological/mechanical properties and degradation/adhesion test of the platelet‑-rich fibrin (PRF) m...
