Characterization of aortic root atherosclerosis in ApoE knockout mice: High‐resolution in vivo and ex vivo MRM with histological correlation

“…Unlike formalin, it does not have a residual MR signal and does not interfere with signal from various biological tissues. Previous in vivo and ex vivo animal and human studies found no toxicity, irritancy, or mutagenicity from Fomblin (13). Since the aortic root presents a technical challenge for MRM due to cardiac motion, stable cardiac gating was essential to ensure the quality of the in vivo images.…”

Formation and properties of composites based on microgels of a responsive polymer and TiO2 nanoparticles

“…Composite materials containing polymeric and inorganic units have been attracting considerable attention in the areas of medicine, paint, and specialty chemical industries [1][2][3][4]. For example, polymer-inorganic oxide composites are promising candidates as slurries for chemical mechanical polishing [5][6][7] while zinc oxide particles coated with fluoropolymers are an important constituent of cosmetic foundation creams [2].…”

“…For example, polymer-inorganic oxide composites are promising candidates as slurries for chemical mechanical polishing [5][6][7] while zinc oxide particles coated with fluoropolymers are an important constituent of cosmetic foundation creams [2]. Composites of poly(vinyl alcohol)-TiO 2 are being examined as a cheap replacement for nafion-platinum membranes for application in alkaline direct methanol fuel cells [3].…”

Per- and polyfluorinated substances in the Nordic Countries

“…A study evaluating the safety of PEFPs, tested the representative Fomblin HC in experimental animals for acute, subacute toxicity, in vitro mutagenicity and irritancy or sensitization on human skin (Malinverno et al, 1996). Daily oral administration (1,000 mg/kg/day) to rats over 28 days produced no significant reaction.…”
