Changes in Urotensin-II (U-II) concentration, a potent vasoconstrictor peptide, have been detected in various pathologies, but it has been impossible to define a normality range. We aimed to analyze the concordance and interchangeability between two enzyme immunoassay methods developed by Phoenix Pharmaceuticals, Inc. to measure U-II plasma concentration in rats: ELISA and fluorescent EIA. Assays resulted positively correlated (r = 0.850; p < 0.01). There was a significant difference between assays values (p < 0.001). The analysis of agreement (Bland and Altman plot) stated that the mean of the differences was 2.055 (SD ± 0.588). Hence, we concluded that the two U-II assays were correlated but not interchangeable.

Introduction: Eosinophil-derived neurotoxin (EDN) is a promising biomarker for eosinophil activation during inflammatory responses. Here we evaluate the analytical performance of an automated fluorescence enzyme immunoassay for EDN in serum and explore its relationship with eosinophil counts in both healthy participants and those with eosinophilic conditions.
Materials And Methods: Paired serum samples were collected from individuals for whom a complete blood count with differential was ordered.

E-selectin (CD62E) is an adhesion molecule expressed on the surface of endothelial cells (ECs) and its level increases significantly upon the stimulation of ECs by inflammatory factors. Quantitative analysis of CD62E is of great importance to early diagnosis and treatment of vascular diseases and hypertension. A new method for the determination of CD62E was developed using a portable pH meter in this work.

Crimean-Congo hemorrhagic fever (CCHF) is a serious tick-borne disease with a wide geographical distribution. Classified as a level 4 biosecurity risk pathogen, CCHF can be transmitted cross-species due to its aerosol infectivity and ability to cause severe hemorrhagic fever outbreaks with high morbidity and mortality. However, current methods for detecting anti-CCHFV antibodies are limited.

Both hydrogen sulfide and endocannabinoids can protect the neural retina from toxic insults under in vitro and in vivo conditions. The aim of the present study was two-fold: (a) to examine the neuroprotective action of cannabinoids [methanandamide and 2-arachidonyl glycerol (2-AG)] against hydrogen peroxide (HO)-induced oxidative damage in the isolated bovine retina and (b) to evaluate the role of endogenously biosynthesized hydrogen sulfide (HS) in the inhibitory actions of cannabinoids on the oxidative stress in the bovine retina. Isolated neural retinas from cows were exposed to oxidative damage using HO (100 µM) for 10 min.
