Clinical Utility of Fecal Immunochemical Transferrin Test in Gastrointestinal Bleeding Detection

Annals of Clinical Microbiology, 2018
Background: Gastrointestinal (GI) bleeding can result from various conditions, including ulcers, neoplasms and infectious enterocolitis. The aim of this study was to evaluate the utility of the fecal immunochemical transferrin test compared with the ...

Proteomic and Postproteomic Characterization of Keratan Sulfate-Glycanated Isoforms of Thyroglobulin and Transferrin Uniquely Elaborated by Papillary Thyroid Carcinomas. [PDF]

, 2003
Previous studies have suggested that surface components of papillary thyroid carcinoma (PTC) cells may be aberrantly glycanated, but the precise nature of these molecules has not been unveiled nor documented to be of clinical relevance.

Transferrin Functionalized Liposomes Loading Dopamine HCl: Development and Permeability Studies across an In Vitro Model of Human Blood–Brain Barrier

Nanomaterials, 2018
The transport of dopamine across the blood brain barrier represents a challenge for the management of Parkinson’s disease. The employment of central nervous system targeted ligands functionalized nanocarriers could be a valid tactic to overcome this ...

Pre‐culture with transferrin‐Fe3+ before in vitro maturation improves the developmental competence of porcine oocytes matured in vitro

Reproductive Medicine and Biology, 2023
Purpose Since the developmental competence of oocytes cultured after in vitro maturation (IVM) is low, it is necessary to improve the IVM method for efficient offspring production.

Transferrin Saturation and Mortality [PDF]

Clinical Chemistry, 2011
To the Editor: Ellervik and colleagues (1) recently reported a positive association between transferrin saturation (TS) and mortality. Several questions arise from this observation: Is the association due to all causes of iron overload or to hereditary hemochromatosis only? Does the study underestimate the true association?

Extraintestinal pathogenic Escherichia coli utilizes the surface-expressed elongation factor Tu to bind and acquire iron from holo-transferrin

, 2022
Extraintestinal pathogenic Escherichia coli (ExPEC) is a common anthropozoonotic pathogen that causes systemic infections. To establish infection, ExPEC must utilize essential nutrients including iron from the host.

Iron metabolism and peripheral eosinophil count do not correlate in the general population

Journal of Biological Research, 2023
Iron is a primary component of the human body and exerts many functions, mainly concerning red cells and the immune system. In addition, there is evidence that iron-deficiency anemia is associated with allergic diseases. Type 2 inflammation characterizes

Zinc Supplementation Combats Tuberculosis by Reverting Back to Normal Compartmentalized State of Iron and Hence Increasing Blood Hemoglobin Concentration [PDF]

Indian Journal of Medical Biochemistry, 2023
Aim and background: To acquire iron (Fe), Mycobacterium tuberculosis (Mtb) expresses high-affinity Fe+3-specific siderophores for scavenging Fe from host insoluble and protein-bound iron-like transferrin, lactoferrin, ferritin, and hemoglobin−haptoglobin.

Transferrins [PDF]

European Journal of Biochemistry, 1998
Fe(III) uptake by the iron‐delivery and iron‐scavenging protein, hen ovotransferrin has been investigated in vitro between pH 6.5 and 9. In the absence of any ferric chelate, apo‐ovotransferrin loses two protons with K1a = 50 ± 1 nM and K2a = 4.0 ± 0.1 nM.

Urea Gel Electrophoresis in Studies of Conformational Changes of Transferrin on Binding and Transport of Non-Ferric Metal Ions

Gels, 2021
Transferrin (Tf) is a crucial transporter protein for Fe(III), but its biological role in binding other metal ions and their delivery into cells remain highly controversial.
