In this study, in order to facilitate and accelerate the production of eukaryotic protein alpha 1-antitrypsin (AAT) with correct post-translational modifications, a protein production system based on the transduction of CHO and COS-7 cells using lentiviral vectors was developed. Human AAT cDNA was cloned into a replication-defective lentiviral vector. The transgene AAT-Jred chimer was transferr...

     Among the numerous nanosized drug delivery systems currently under investigation, carbon nanotubes (CNTs), regardless of being single or multiple-walled, offer several advantages and are considered as promising candidates for drug targeting. Despite the valuable potentials of CNTs in drug delivery, their toxicity still remains an important issue. After the PEGylation of single-walled CNTs ...

conclusions ultimately, we can conclude that the hemoglobin level at the time of admission and before delivery, the type of disease, gestational age, and transfusion could be effective factors of patient mortality. results the mean maternal age was 27.60 ± 6.37 years. the hemoglobin level at hospital admission was 8.9 ± 1.61 g/dl for the survivors and 7.73 ± 1.19 g/dl for the deceased patients ...

Extracellular vesicles (EVs) are submicron cell-secreted structures containing proteins, nucleic acids and lipids. EVs can functionally transfer these cargoes from one cell to another modulate physiological pathological processes. Due their presumed biocompatibility capacity circumvent canonical delivery barriers encountered by synthetic drug systems, have attracted considerable interest as veh...

in this research, hydrogels based on poly vinyl alcohol and poly acrylic acid blend were prepared which were cross-linked by applied thermal conditions. afterward, effects of time and heating on water uptake were investigated. the highest water uptake value exhibited by the sample that was heated for 20 min. at 110 ºc was about 2129% after 4 days at equilibrium state. hydrogels exhibited ph-sen...

Cell-based therapies have been increasingly explored as a potential alternative treatment method of corneal endothelial dysfunction. Up to date, researchers have mainly dedicated enormous efforts to establishing fundamental techniques for culture and characterization of human corneal endothelial cells (HCECs) and human corneal endothelial progenitor cells (HCEPCs). However, in terms of cell del...
