We have studied the pharmacokinetics of desferrioxamine (DFA), ferrioxamine (FeA) and aluminoxamine (AlA) in patients with chronic renal failure on continuous ambulatory peritoneal dialysis (CAPD) after 10 mg/kg (15.24 mumol/kg) body weight desferrioxamine (DESFERAL) administration by intramuscular and intraperitoneal routes. The results show an easy exchange of DFA between the plasma and the peritoneal fluid regulated by the relative concentrations of DFA in the two compartments. When the equilibrium is reached, the concentration of DFA are approximately the same in the plasma and the peritoneal fluid.

Amyotrophic lateral sclerosis (ALS) is a rare neurodegenerative disease characterized by motor neuron loss in the motor cortex, brain stem, and spinal cord. Mutations in the superoxide dismutase 1 (SOD1) gene, resulting in misfolding of its protein product, are a common cause of ALS. Currently, there is no approved ALS diagnostic tool.

Fcγ receptors (FcγR) are responsible for many of the interactions between immunoglobulins (IgG) and immune cells. In biomedicine, this interplay is critical to the activity of several types of immunotherapeutics; however, relatively little is known about how FcγRs affect the in vivo performance of radiolabeled antibodies. A handful of recent preclinical studies suggest that binding by FcγR-and particularly FcγRI-can affect the pharmacokinetic profiles of Zr-labeled radioimmunoconjugates, but there are no extant studies in immunocompetent or genetically engineered mouse models of cancer.

Background: Delayed diabetic wound healing is one of the clinical difficulties, the main reason is the limited angiogenesis ability. Deferriamine (DFO) is an iron chelating agent that can induce angiogenesis, but its application is limited due to its short half-life. Increasing the load and slow release performance of desferriamine is beneficial to accelerate diabetic wound healing.

Purpose: To avoid the biotoxicity and poor bioavailability of deferoxamine mesylate (DFO), an iron chelation for the treatment of Parkinson's disease (PD), a self-oriented DFO nanoparticle functionalized with Exendin-4 was developed, which can be targeted delivered into the lesion brain area to achieve synergistic effects against PD by iron chelation and inflammatory suppression.
Methods: The self-oriented DFO nanoparticles (Ex-4@DFO NPs) were synthesized by double emulsion technique, and characterized in terms of the particle size, morphology and DFO encapsulation efficiency. The cellular internalization, biocompatibility and cytoprotection of NPs were assessed on BV-2 and SH-SY5Y cells.
