pteridine/breast neoplasms

Recent preliminary studies have implicated urinary pteridines as candidate biomarkers in a growing number of malignancies including breast cancer. While the developments of capillary electrophoresis-laser induced fluorescence (CE-LIF), high performance liquid chromatography (HPLC), and liquid

BACKGROUND Urinary biomarkers, such as pteridines, require normalization with respect to an individual's hydration status and time since last urination. Conventional creatinine-based corrections are affected by a multitude of patient factors whereas urine specific gravity (USG) is a bulk specimen

We really appreciate the comments from Drs. Reibnegger and Fuchs regarding our recent publication "Normalization of urinary pteridines by urine specific gravity for early cancer detection [Clin. Chim. Acta 435 (2014) 42-47]". In their letter, Drs. Reibnegger and Fuchs identify several potential

BACKGROUND Biomarkers are good potential tools for early cancer diagnosis. Here we have analyzed eight different pteridines in the urine samples of cancer patients and compared them with samples from healthy subjects. Pteridines are important cofactors in the process of cell metabolism, and they

A new strategy is developed for construction of the mixed molecular nanostructures from folic acid (FOA), a targeting agent, and deferrioxamoine-Ga(III), (DFO-Ga(III)), a theranostic agent, on gold-mercaptopropionic acid surface, Au-MPA. The strategy is focused to achieve a system in which all the

A number of new asymmetric azines derived from hydrazine and 6-acetyl-1,3,7-trimethyllumazine (lumazine=pteridine-2,4(1H,3H)-dione) and its derivatives with several aromatic aldehydes have been prepared and characterized by usual procedures (XRD, IR, (1)H and (13)C NMR). These were reacted with
