Abstract

As nanotheranostics, Congo red/Rutin-MNPs combine the abilities of diagnosis and treatment of Alzheimer's disease (AD). The biocompatible nanotheranostics system based on iron oxide magnetic nanoparticles, with ultrasmall size and excellent magnetic properties, can specifically detect amyloid plaques by magnetic resonance imaging, realize targeted delivery of AD therapeutic agents, achieve drug controlled release by H2O2 response, and prevent oxidative stress.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • A significant portion of studies use MRI with contrast agents based on gadolinium, SPIONs, or manganese ions, reflecting the researchers' desire to create platforms potentially applicable in clinical practice.

    “A significant portion of the studies use MRI with contrast agents based on gadolinium [70,71], SPIONs [58,63,73,83], or manganese ions [72], reflecting the researchers’ desire to create platforms potentially applicable in clinical practice.”
  • Many studies include an antioxidant component aimed at reducing ROS and an anti-inflammatory effect via delivery of immunosuppressants.

    “Many studies also include an antioxidant component aimed at reducing the level of ROS [64,72,78,80,83], and an anti-inflammatory effect, implemented through the delivery of immunosuppressants [70,71].”
  • CDs and triggerable-release systems appear particularly promising for further development, as they address two key challenges: CDs combine intrinsic fluorescence with therapeutic activity in a single ultrasmall particle, while triggerable-release systems enable on-demand therapy activation using pathological signals, mitigating dose and pharmacokinetic conflicts.

    “Among the platforms surveyed, CDs [78,79] and triggerable-release systems [83] appear particularly promising for further development, as they address two key challenges identified in our analysis: CDs combine intrinsic fluorescence with therapeutic activity in a single ultrasmall particle (bypassing the need for additional diagnostic labels), while triggerable-release systems enable on-demand ther”
  • The effectiveness of therapy is confirmed in most studies on cellular models, where a significant increase in survival of neuronal cells upon exposure to toxic concentrations of Aβ is shown.

    “The effectiveness of therapy is confirmed in most studies on cellular models, where a significant increase in the survival of neuronal cells upon exposure to toxic concentrations of Aβ is shown [29,64,72,76,77,78,80,83].”
  • In animal models, reduction in amyloid plaque burden, decrease in neuroinflammation and oxidative stress, and improvement in cognitive functions in behavioral tests have been demonstrated.

    “In animal models, a reduction in the burden of amyloid plaques [58,68,75], a decrease in neuroinflammation and oxidative stress, as well as an improvement in cognitive functions in behavioral tests [58,64,72,73,83,85] have been demonstrated.”

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.
