OBJECTIVE To observe the influence of Fe3O4-dextran-anti-β-human chorionic gonadotropin (HCG) carrying heparanase (Hpa) antisense oligodeoxynucleotide (ASODN), via the invasion, proliferation, and Hpa expression of JEG-3 cell lines and inhibitory effect of transplanted choriocarcinoma tumor growth. METHODS The different abilities of invasion and proliferation between transfected JEG-3 and unt...

able amounts of radiolabeled dextran in the plasma protein fraction [15]. Consequently, we do not think this mechanism plays a substantial role in producing the lower than expected dextran concentrations seen in the present study. The dextran we used had a mean molecular mass of 70 000 Da. Thus, some quantity of lower-molecular-mass dextran could have leaked out of the vascular space and distri...

Extreme hemodilution was performed in the hamster chamber window model using 6% Dextran 70, lowering systemic hematocrit by 60%. Animals were subsequently divided into three groups and hemodiluted to a hematocrit of 11% using 6% Dextran 70, 6% Dextran 500, and a 4% Dextran 70 + 0.7% alginate solution (n = 6 each group). Final plasma viscosities were 1.4 +/- 0.2, 2.2 +/- 0.1, and 2.7 +/- 0.2 cp,...

INTRODUCTION Expansion of efficacious theranostic systems is of pivotal significance for medicine and human healthcare. Magnetic nanoparticles (MNPs) are known as drug delivery system and magnetic resonance imaging (MRI) contrast agent. MNPs as drug carriers have attracted significant attention because of the delivery of drugs loaded onto MNPs to solid tumors, maintaining them in the target sit...

Binding constants of the dextran-reactive BALB/c mouse IgA myeloma proteins W3129 and QUPC 52 have been determined for each member of the isomaltose series of oligosaccharides and for methyl alphaDglucoside. Protein W3129 has maximum complementarity for isomaltopentaose (IM5) deltaf degrees = 7,180 cal/mol) with 55-60% of the total binding energy directed against methylalphaDglucoside. Protein ...

In this study, we aimed to determine the in vitro activity of Leuconostoc mesenteroides var. isolatedfrom sugar-industry effluents produce a dextran bioflocculant from sucrose as low-cost substrate.L. strains present residual cane juice sugar factory were isolated and biochemicallyidentified using Mayeux, Sandine, Elliker agar (MSE) selective medium. The strain number 3 (LM03) wasbiochemically ...
