Abstract

An in vivo rat cage implant system was used to identify potential surface chemistries that prevent failure of implanted biomedical devices and prostheses by limiting monocyte adhesion and macrophage fusion into foreign-body giant cells while inducing adherent-macrophage apoptosis. Hydrophobic, hydrophilic, anionic, and cationic surfaces were used for implantation. Analysis of the exudate surrounding the materials revealed no differences between surfaces in the types or levels of cells present. Conversely, the proportion of adherent cells undergoing apoptosis was increased significantly on anionic and hydrophilic surfaces (46 ± 3.7 and 57 ± 5.0%, respectively) when compared with the polyethylene terephthalate base surface. Additionally, hydrophilic and anionic substrates provided decreased rates of monocyte/macrophage adhesion and fusion. These studies demonstrate that biomaterial-adherent cells undergo material-dependent apoptosis in vivo , rendering potentially harmful macrophages nonfunctional while the surrounding environment of the implant remains unaffected.

  • Biomaterial surface chemistry influences apoptosis of adherent macrophages both in vitro and in vivo.

    “Biomaterial surface chemistry influences apoptosis of adherent macrophages both in vitro and in vivo.[12, 53–55]”

    From Foreign body reaction to biomaterials (2008) · cites this paper as [54]

    The Results (page not provided) show that surface chemistry affected adherent-macrophage apoptosis in vivo. The paper also reports in its introductory text (page not provided) an earlier in vitro finding for biomaterial-adherent cells, but does not specify there that those cells were macrophages. Thus, the in vitro macrophage-specific part is not established by our copy. (LLM, conf=0.83)

  • Adherent inflammatory cell apoptosis is an important mechanism for the persistence of cardiovascular device infection where apoptosis is induced by shear stress in cardiovascular devices.

    “Adherent inflammatory cell apoptosis has been described as an important mechanism for the persistence of cardiovascular device infection where apoptosis is induced by shear stress in cardiovascular devices.[54]”

    From Foreign body reaction to biomaterials (2008) · cites this paper as [54]

    The Abstract (page unavailable) reports that fluid shear stress causes apoptosis of biomaterial-adherent neutrophils and says this may increase cardiovascular prostheses’ susceptibility to bacterial infection. It does not establish apoptosis as an important mechanism for the persistence of an existing device infection; that is stronger and more specific than the paper’s tentative statement. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Hydrophilic, anionic surfaces promote the highest levels of apoptosis of biomaterial adherent FBGC.

    “In a previous study by Brodbeck et al. [50], it was reported that hydrophilic, anionic surfaces promoted the highest levels of apoptosis of biomaterial adherent FBGC.”
  • Inducing apoptosis in adhered FBGC would reduce the negative effects of adhered cells and improve tissue remodeling.

    “Since FBGC are detrimental to the biomaterial due to their ability to increase oxidative damage and recruit other inflammatory cells, the authors proposed that inducing apoptosis in the adhered FBGC would reduce the negative effects of adhered cells and improve tissue remodeling [50,51].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
