Absorbable topical hemostatic agents are commonly used in cardiac surgery. In this study, we report an unusual case of an acute ischemic event after coronary revascularization produced by interaction between oxidized cellulose and epsilon aminocaproic acid (EACA). An in vitro study was also performed to test the interaction between oxidized cellulose and EACA.

The cytotoxicity and in vitro effects of six variously modified types of cellulose (OC--oxidized cellulose, NaOC--oxidized cellulose sodium salt, DAC--dialdehyde cellulose, CMC--carboxymethyl cellulose, MFC--microfibrilated cellulose, and MCC--microcrystalline cellulose) on the inflammatory response in macrophage-like THP-1 cells were examined, with special focus on their ability to influence g...

Nitidon, a highly oxidised pyranone derivative produced by the basidiomycete Junghuhnia nitida, has been isolated and its biological activities evaluated. The structure was determined by spectroscopic methods. Nitidon exhibits antibiotic and cytotoxic activities and induces morphological and physiological differentiation of tumor cells at nanomolar concentrations.

BACKGROUND The purpose of this retrospective study was to identify an appropriate material that can be used as a covering for patients with a spontaneous pneumothorax (SP). A total of 279 patients were studied over a period of eight years. METHODS The patient characteristics, surgical details and perioperative outcomes were analyzed. We compared the clinicopathological characteristics between...

The crystallinity of cellulose is one of the main structural parameters determining properties like accessibility and reactivity of cellulose. Native cellulose (e.g., wood, pulp, cotton, kenaf, bacteria cellulose) consists of the cellulose I, regenerated cellulose consists of the cellulose II modification. WAXS (wide angle X-ray scattering) is the standard method for the determination of crysta...

Novel thin and smooth deuterated cellulose films were synthesised to visualize adsorbed bio-macromolecules using contrast variation neutron reflectivity (NR) measurements. Incorporation of varying degrees of deuteration into cellulose was achieved by growing Gluconacetobacter xylinus in deuterated glycerol as carbon source dissolved in growth media containing D2O. The derivative of deuterated c...

We covalently linked to regenerated cellulose filters a high-affinity monoclonal IgM produced against epitopes that reside on hepatitis B viral surface antigen (HBsAg). Conditions were established whereby as much as 250 micrograms of anti-HBsAg IgM could be linked to 2-4 mg of regenerated cellulose acetate by using cyanogen bromide and trichloro-s-triazine coupling agents. The immunoreactivity ...
