Biodegradable poly-(D,L-lactide-co-glycolide) microspheres (PLGA-MS) are approved as a drug delivery system in humans and represent a promising antigen delivery device for immunotherapy against cancer. Immune responses following PLGA-MS vaccination require cross-presentation of encapsulated antigen by professional antigen presenting cells (APCs). While the potential of PLGA-MS as vaccine formul...
BACKGROUND Particulate carriers are necessary to control the release of endostar and prolong its circulation in vivo. The purpose of this study was to identify a suitable carrier for the capsulation and delivery of endostar. METHODS We prepared a series of poly (DL-lactide-co-glycolide) (PLGA) and poly (ethylene glycol) (PEG)-modified PLGA (PEG-PLGA) particulate carriers, and then characteriz...
Environmental impacts caused by tin and copper based commercial antifouling (AF) paints were proved to be detrimental to aquatic ecosystems. Therefore, a search of environmental friendly AF compounds to be used in marine paint to protect the surface of maritime developmental structures from the unwanted biofouling is a burning issue of the present time. Commercially available eight organic chem...
Introduction: Hepatitis C virus (HCV) is one of the most serious causes of cirrhosis, liver cancer and ultimately death, worldwide. The new direct-acting drugs are not accessible for many patients around the world and progress toward new therapeutic and anaphylactic vaccines design has not been fast enough. This study was aimed to prepare and assess a recombinant fusion protein core-NS3 (rC-N) ...
Nanoscaled devices have great potential for drug delivery applications due to their small size. In the present study, we report for the first time the preparation and evaluation of antitumor efficacy of 5-fluorouracil (5-FU)-entrapped poly (D, L-lactic-co-glycolic acid) (PLGA) nanoparticles with dependence on the lactide/glycolide combination of PLGA. 5-FU-loaded PLGA nanoparticles with two dif...
A decrease in methanogenesis is expected to improve ruminant performance by allocating rumen metabolic hydrogen ([2H]) to more energy-rendering fermentation pathways for the animal. However, decreases in methane (CH4) emissions of up to 30% are not always linked with greater performance. Therefore, the aim of this study was to understand the fate of [2H] when CH4 production in the rumen is inhi...
Polylactic-co-glycolic acid (PLGA) based nanoparticles are biocompatible and biodegradable and therefore have been extensively investigated as therapeutic carriers. Here, we engineered diagnostically active PLGA nanoparticles that incorporate high payloads of nanocrystals into their core for tunable bioimaging features. We accomplished this through esterification reactions of PLGA to generate p...
حفاظت از گروههای عاملی از مراحل اجتناب ناپذیر در سنتز آلی است، در این بین محافظت از گروههای آمینی بسیار حائز اهمیت است. روشهای متعددی از قبیل فرمیله کردن، استیله کردن، محافظت بصورت boc و موارد زیاد دیگری جهت محافظت از گروههای آمینی تاکنون گزارش شده است. از طرف دیگر توسعه و کاربرد کاتالیست ها و حلالهای دوستدار محیط زیست و مزایای واکنشهای بدون حلال همچون سرعت بالای واکنش، خالص سازی آسان، کاهش آلو...
The aim of this study was to evaluate the biological activity, safety, and effectiveness poly(lactic acid)–poly(glycolic acid)–poly(ethylene glycol)–calcium phosphate cement (PLGA-PEG-PLGA/CPC). Methods: PLGA-PEG-PLGA/CPC composite bone used for interaction with MC3T3-E1 mouse osteoblasts in vitro its compatibility tested using Cell Counting Kit-8 (CCK-8). Alizarin Red staining alkaline phospha...
The aim of the current study was to investigate the antitumor potential of poly (D,L-lactic-co-glycolic acid) microspheres (PLGA MSs) containing polyethylene glycol (PEG)-conjugated (PEGylated) tumor necrosis factor-related apoptosis-inducing ligand (PEG-TRAIL). PEG-TRAIL PLGA MSs were prepared by using a water-in-oil-in-water double-emulsion method, and the apoptotic activities of supernatants...
