13. Effect of carbopol and polyvinylpyrrolidone on the mechanical, rheological, and release properties of bioadhesive polyethylene glycol gels
This study examined the mechanical (hardness, compressibility, adhesiveness, and cohesiveness) and rheological (zero-rate viscosity and thixotropy) properties of polyethylene glycol (PEG) gels that contain different ratios of Carbopol 934P (CP) and polyvinylpyrrolidone K90 (PVP). Mechanical properties were examined using a texture analyzer (TA-XT2), and rheo

14. Chitosan film containing fucoidan as a wound dressing for dermal burn healing: Preparation and in vitro/in vivo evaluation
The aim of this study was to develop chitosan film containing fucoidan and to investigate its suitability for the treatment of dermal burns on rabbits. Porous films, thickness between 29.7 and 269.0 μm, were obtained by the solvent dropping method. Water vapor permeability (3.3–16.6/0.1 g), the swelling (0.67–1.77 g/g), tensile strength (7.1–45.8 N),

15. Formation of transmural complement pores in serum-sensitive Escherichia coli.
The binding of C9 at 0 and 37 degrees C to viable Escherichia coli K-12 cells carrying C5b-8 complexes was quantified. At low temperature, limited average binding of only 1 to 1.4 molecules of C9 per C8 molecule occurred, whereas 6 to 8 C9 molecules were bound per C8 molecule at 37 degrees C. Despite incorporation of C9 into C5b-9 complexes at 0 degrees C, t
