DEVELOPMENT OF DELIVERY SYSTEM FOR TRANSFERRIN USING CHEMICAL MODIFICATION APPROACH [PDF]

open access: yesBasrah Journal of Veterinary Research, 2012
Proteins are very important molecules as therapeutics. They have several advantages over small molecule drugs but their use is limited by their circulation short half life, immunogenicity and physicochemical instability.

Characterization of pre-existing anti-PEG and anti-AGAL antibodies towards PRX-102 in patients with Fabry disease

open access: yesFrontiers in Immunology, 2023
Polyethylene glycol (PEG)ylated drugs are used for medical treatment, since PEGylation either decreases drug clearance or/and shields the protein from undesirable immunogenicity.

The half-life of the bone-derived hormone osteocalcin is regulated through O-glycosylation in mice, but not in humans

open access: yeseLife, 2020
Osteocalcin (OCN) is an osteoblast-derived hormone with pleiotropic physiological functions. Like many peptide hormones, OCN is subjected to post-translational modifications (PTMs) which control its activity.

The half-life of 129I [PDF]

open access: yesApplied Radiation and Isotopes, 2018
The radionuclide 129I is a long-lived fission product that decays to 129Xe by beta-particle emission. It is an important tracer in geological and biological processes and is considered one of the most important radionuclides to be assessed in studies of global circulation. It is also one of the major contributors to radiation dose from nuclear waste in

Determining the Time of Booster Dose Based on the Half-Life and Neutralization Titers against SARS-CoV-2 Variants of Concern in Fully Vaccinated Individuals

open access: yesMicrobiology Spectrum, 2023
Although mRNA-based COVID-19 vaccines reduce the risk of severe disease, hospitalization and death, vaccine effectiveness (VE) against infection and disease from variants of concern (VOC) wanes over time.
