Using the inclusion complex of trans azobenzene and cyclodextrin as a photo-switchable crosslinker, a dextran based photo-responsive hydrogel system has been constructed and employed for a light controlled protein release system.

When a total dose infusion of iron dextran is given to anaemic rheumatoid patients an exacerbation of inflammatory synovitis in previously affected joints is observed. The adjuvant arthritis model of inflammation in rats has been used to investigate the mechanism of iron promoted synovitis. Either iron dextran (5 mg injected intravenously) with a dextran C control, or iron sorbitol (7.5 mg inje...

Anemia is a very common clinical problem in patients with chronic kidney disease (CKD) and is associated with increased morbidity and mortality in these patients. Erythropoietin is a hormone synthesized that is deficient in the majority of patients with advanced kidney disease, thereby predisposing these patients to anemia. The other cause of anemia is deficiency of iron. Iron deficiency anemia...

The functionalization of polysaccharides with synthetic nanopolymers has attracted great attention owing to the applications this method in many industrial fields. This work aimed investigate effect arsenic trioxide on dextran. Dextran-arsenite nanoparticle formation was induced by microwave sulfuric acid as a catalyst. Various analytical techniques were used verify structure nanopolymers. Besi...

In assay of serum proteins by use of the biuret reaction, dextran can cause turbidity by formation of an insoluble complex of dextran with copper and tartrate (or EDTA) in strongly alkaline solution. Whether or not the turbidity occurs depends on the tartrate concentration: turbidity is maximal at about 10 g/L, absent at 20 g/L or more, and only slight and delayed at 4 g/L. Two biuret reagents,...

Multilayer microcapsules showing unique charge-controlled permeability have been successfully fabricated by employing poly(styrene sulfonate) (PSS)-doped CaCO3 particles as templates. Encapsulation of the PSS molecules is thus achieved after core removal. Scanning force microscopy (SFM), UV-vis, Raman spectroscopy, and zeta-potential confirm the existence of the PSS molecules in the CaCO3 parti...

the present study was designed to assess the cytotoxicity, anti-inflammatory and analgesic properties of methanol extract of woodfordia fruticosa flowers. cytotoxic activity of methanol extract of woodfordia fruticosa flowers was tested using artemia salina (brine shrimp) bioassay. two doses (400 and 600 mg/kg) were evaluated for the anti-inflammatory activity against the carrageenan, histamine...

The aim of this research was to investigate the effect non-invasive dermal electroporation (EP) on barrier function skin and permeation a model macromolecule in combination with different formulations. Skin samples were treated EP treatment for 2 min. Firstly, examined mouse vivo by measuring transepidermal water loss (TEWL). Then, human investigated ex under fluorescence microscope solution, h...

The first life was believed to emerge in the early Earth via a process involving synthesis of organic compounds and formation protocells. However, it is still puzzle how protocell with hierarchal structure desirable functions spontaneously generated non-living environment composed mainly water minerals. In this work, using muscovite as an example minerals, we systemically studied coacervation p...
