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 ...

Neopterin as an endogenous antioxidant [PDF]

FEBS Letters, 1992
The in vitro potency of neopterin (NP) as an antioxidant and its in vivo activity to suppress alloxan‐induced diabetes were investigated. The reduced form of neopterin, 5,6,7,8‐tetrahydroneopterin (NPH‐4), showed an extremely high superoxide anion radical scavenging activity in two assay systems, i.e.

Gut function among children treated for severe acute malnutrition: A cohort study in Uganda. [PDF]

JPGN Rep
Abstract Objectives Impaired gut function in children with severe acute malnutrition (SAM) is associated with morbidity. We aimed to assess changes in six biomarkers representing different domains of gut function among children with complicated SAM during nutritional rehabilitation, and to identify predictors of these changes.

Neopterin as Tumour Marker Serum and Urinary Neopterin Concentrations in Malignant Diseases [PDF]

Clinical Chemistry and Laboratory Medicine, 1986
Serum and urinary neopterin concentrations were measured in 142 patients suffering from various malignant diseases. Increased serum and urinary neopterin levels were found in 48% and 55% of patients respectively. Neopterin showed sufficient sensitivity in the detection of haematological disorders and hypernephroma, whereas the sensitivity of neopterin ...
