Urinary Neopterin in Patients with Advanced Colorectal Carcinoma

The International Journal of Biological Markers, 2006
In previous studies, mostly in patients with early stage colorectal carcinoma, neopterin, an indicator of systemic immune activation, has been associated with poor prognosis. The aim of the present study was to evaluate urinary neopterin in patients with

Neopterin as a diagnostic biomarker for diagnosis of inflammatory diseases like periodontitis

Journal of Oral Research and Review, 2017
Neopterin is a catabolic product of guanosine triphosphate, a purine nucleotide and belongs to the group pteridines. When the cytokine interferon gamma stimulates the human macrophages, they synthesize the neopterin.

Longitudinal changes in plasma biomarkers of immune activation, neuronal inflammation and injury in persons with HIV initiating ART. [PDF]

HIV Med
Abstract Background Data on changes in biomarkers of brain health, and their associations with cognitive function in adults commencing either dual‐ or triple‐antiretroviral therapy (ART) are sparse. Methods Plasma biomarkers (neurofilament light [NfL], glial fibrillary acidic protein [GFAP], sCD14, CXCL10, neopterin and IL‐6) were measured at baseline ...

Effects of extreme mountain ultramarathon on stress-related biomarkers from multiple biological matrices in adult male runners. [PDF]

Physiol Rep
Abstract Prior investigations concerning finishers of the Tor des Géants (TDG) have demonstrated oxi‐inflammatory response. MicroRNAs (miRNAs) have been identified as prospective biomarkers for oxi‐inflammatory and stress responses. This study addressed the acute responses concerning salivary miRNAs, circulating redox markers and urinary exercise ...

An Overview of Pterin Analysis in Biological Samples: From Occurrence and Properties to Sample Pretreatment Combined With Hyphenated Separation Techniques. [PDF]

J Sep Sci
ABSTRACT Pterins are a structurally diverse group of biologically active compounds within the pteridine family, with key roles in pigmentation, redox metabolism, light sensing, and cellular signaling across a wide range of organisms. Their quantification in biological samples is analytically demanding due to their high polarity, chemical instability ...
