Framework selection can influence pharmacokinetics of a humanized therapeutic antibody through differences in molecule charge.

Pharmacokinetic (PK) testing of a humanized (κI, VH3 framework) and affinity matured anti-hepatitis C virus E2-glycoprotein (HCV-E2) antibody (hu5B3.κ1VH3.v3) in rats revealed unexpected fast clearance (34.

Comparative physiology of mice and rats: radiometric measurement of vascular parameters in rodent tissues.

A solid understanding of physiology is beneficial in optimizing drug delivery and in the development of clinically predictive models of drug disposition kinetics. Although an abundance of data exists in the literature, it is often confounded by the use of various experimental methods and a lack of consensus in values from different sources. To help address this deficiency, we sought to directly compare three important vascular parameters at the tissue level using the same experimental approach in both mice and rats.

Iron accumulation during cellular senescence.

Iron accumulates as a function of age and is associated with the pathology of numerous age-related diseases. These changes may be caused by altered iron homeostasis at the cellular level, yet this is poorly understood. Therefore, changes in iron content in primary human fibroblasts were studied in culture models of cellular senescence.
