INTRODUCTION Rheumatoid arthritis (RA) is a T-cell-mediated systemic autoimmune disease, characterized by synovium inflammation and articular destruction. Bone marrow mesenchymal stem cells (MSCs) could be effective in the treatment of several autoimmune diseases. However, there has been thus far no report on umbilical cord (UC)-MSCs in the treatment of RA.(More)
OBJECTIVES Ovariectomized (OVX) rat model has been widely used in osteoporosis-related studies. However, the discrepancies in age and skeletal sites being investigated make it difficult to compare the results from different studies. The purpose of this study was to provide information of systemic skeletal site-specific changes in a stable OVX rat model. (More)
Starch is the most widespread and abundant storage carbohydrate in crops and its production is critical to both crop yield and quality. In regard to the starch content in the seeds of crop plants, there is a distinct difference between grasses (Poaceae) and dicots. However, few studies have described the evolutionary pattern of genes in the starch(More)
Mitoxantrone (MIT) was encapsulated into 60, 80 and 100nm pegylated hydrogenated soy phosphatidylcholine/cholesterol (HSPC/chol) vesicles using a transmembrane (NH(4))(2)SO(4) gradient. In-vitro release studies revealed that small-sized formulation had fast drug-release rate. Acute toxicity studies performed in c57 mice proved that all pegylated liposomal(More)
The purpose of this study is to develop novel stable PEGylated liposome vincristine formulations with optimal antitumor efficacy. Vincristine could interact with negatively charged distearoylphosphatidylethanolamine-polyethylene glycol (DSPE-PEG), leading to rapid drug release from vesicles. To improve drug retention, vincristine was loaded into vesicles(More)
BACKGROUND Pemphigus is one of the potentially fatal autoimmune blistering diseases. An early and accurate diagnosis is important for prognosis and therapy. It may be difficult to diagnosis based on clinical grounds alone. Direct and indirect immunofluorescence, enzyme-linked immunosorbent assay, the Tzanck smear test, or histopathology are all available(More)
Mitoxantrone was encapsulated into pegylated SUVs using ammonium sulfate gradient method. Four formulations (LM-s, LM-p, LM-m and LM-m-L) were prepared, which were made from different PCs and exhibited different PEG grafting density. In vitro release studies revealed that drug release rate increased with decreased T(m) of PCs, and reduced PEG polymer(More)
Nanoparticles using albumin as particle matrix have entered the mainstream of drug delivery. It was reported that non-crosslinked albumin nanoparticles were unstable in circulation and could deliver drugs into tumor through gp60/SPARC pathway; in contrast, the delivery of drugs with stable nanoparticles was dependent on enhanced permeability and retention(More)
The objective of this study was to obtain dehydrated liposomes using a novel procedure that involves freeze-drying (FD) of liposomes with TBA/water cosolvent systems. The effects of TBA on the integrity/stability of vesicles of HSPC (or SPC):Cholesterol (4:1) were investigated. TBA used as a cosolvent was detrimental to SPC liposomes, leading to increased(More)
OBJECTIVE To investigate the effectiveness of total glucosides of paeony (TGP) on Sjogren's syndrome (SS) using non-obese diabetic (NOD) mice model. STUDY DESIGN Twenty-seven 8-week-old female NOD mice were assigned into TGP group, hydroxychloroquine (HCQ) group and normal saline (NS) group, receiving corresponding drugs respectively and sacrificed at(More)
