OBJECTIVE To evaluate the feasibility of using magnetic iron oxide (Fe(3)O(4))-dextran-anti-β-human chorionic gonadotropin (HCG) nanoparticles as a gene vector for cellular transfections. STUDY DESIGN Fe(3)O(4)-dextran-anti-β-HCG nanoparticles were synthesized by chemical coprecipitation. The configuration, diameter, and iron content of the nanoparticles were detected by transmission electron...

Quartz crystal microbalance (QCM) has been extensively applied in real-time and label-free biomolecular interaction studies. However, the sensitive detection by QCM technology remains challenging, mainly due to the limited surface immobilization capacity. Here, a three-dimensional (3D) carboxymethyl dextran coated gold sensor chip surface was successfully fabricated with dextran of different mo...

Recent efforts in our laboratory have focused on developing methods for immobilizing bioactive peptides to low cell-adhesive dextran monolayer coatings and promoting biospecific cell adhesion for biomaterial implant applications. In the current study, this dextran-based bioactive coating technology was developed for silicon, polyimide, and gold, the base materials utilized to fabricate our prot...

Dextran sulfate is commonly used with polyethylene glycol to concentrate viruses before extraction of their DNA. However, dextran slulfate then easily contaminated such DNA and acted as a potent inhibitor of DNA polymerases from Bacillus subtilis (III), phage PBS2, and phage T4. Dextran sulfate only weakly inhibited Micrococcus luteus and Escherichia coli DNA polymerase I preparations.

We present a dextran modified silicon microring resonator sensor for high density antibody immobilization. An array of sensors consisting of three sensor rings and a reference ring was fabricated and its surface sensitivity and the limit of detection were obtained using polyelectrolyte multilayers. The mass sensitivity and the limit of detection of the fabricated sensor ring are 0.35 nm/ng mm a...

In this research, a simple and efficient cathodic electrochemical deposition (CED) route wasdeveloped for the preparation of magnetite nanoparticles (NPs) in an aqueous media. Thesurface of magnetite NPs was also coated for the first time via an in situ procedure during theCED process. In this method, initially, the Fe3O4 NPs (with size ~10 nm) were prepared from theFe2+/Fe3+ chloride bath thro...

Background: the supplementation of natural antioxidants such plant flavonoids may counteract the deleterious actions of gamma-irradiation and iron overload. Material and Methods: the protective effect of naringin (NIN) against kidney injury induced by γ-irradiation (IRR) (6.5 Gy) and/or iron dextran (ID) (50 mg/kg. b. w) has been studied in rats given 80 mg/kg b.w of NIN for 14 days before, and...

BACKGROUND Albumin may be beneficial in patients with septic shock but availability is limited and cost is high. The objective of the present study was to investigate if the use of dextran-70 in addition to albumin and crystalloids influences organ failure or mortality in patients with severe sepsis or septic shock. METHODS Patients with severe sepsis or septic shock (n = 778) admitted to a u...
