Mixed Amphiphilic Polymeric Nanoparticles of Chitosan, Poly(vinyl alcohol) and Poly(methyl methacrylate) for Intranasal Drug Delivery: A Preliminary In Vivo Study

Molecules, 2020
Intranasal (i.n.) administration became an alternative strategy to bypass the blood–brain barrier and improve drug bioavailability in the brain. The main goal of this work was to preliminarily study the biodistribution of mixed amphiphilic mucoadhesive ...

Fluorescent Dye Labeling Changes the Biodistribution of Tumor-Targeted Nanoparticles

Pharmaceutics, 2020
Fluorescent dye labeling is a common strategy to analyze the fate of administered nanoparticles in living organisms. However, to which extent the labeling processes can alter the original nanoparticle biodistribution has been so far neglected.

Biodistribution of mild analgesics. [PDF]

British Journal of Clinical Pharmacology, 1980
1 Macro‐autoradiographic methods were used to assess the biodistribution of [3H]‐, or [14C]‐acidic (aspirin, indomethacin, phenylbutazone) and non‐acidic (antipyrine, aminopyrine, paracetamol) mild analgesics in rats with carrageenan‐induced inflammation.

First-in-man evaluation of 124I-PGN650: A PET tracer for detecting phosphatidylserine as a biomarker of the solid tumor microenvironment [PDF]

, 2017
Purpose: PGN650 is a F(ab′) 2 antibody fragment that targets phosphatidylserine (PS), a marker normally absent that becomes exposed on tumor cells and tumor vasculature in response to oxidative stress and increases in response to therapy.

Longitudinal in vivo biodistribution of nano and micro sized hydroxyapatite particles implanted in a bone defect

Frontiers in Bioengineering and Biotechnology, 2022
Hydroxyapatite (HA) has been widely used as a bone substitute and more recently as a carrier for local delivery of bone targeted drugs. Majority of the approved HA based biomaterials and drug carriers comprise of micrometer sized particulate HA (mHA) or ...
