Background: Serum oxidative stress (OS) level has an important role in the inflammatory process of heart failure.
Hypothesis: The study was designed to analyze serum OS levels in chronic heart failure (HF) patients and to examine the relation between OS levels and other clinical and prognostic parameters of HF.
Methods: We studied 82 consecutive chronic symptomatic HF patients with systolic LV dysfunction (ejection fraction <45%). The serum OS level was determined using thermochemiluminescence assay. We compared the serum OS levels with patients' clinical and prognostic parameters.
Results: Higher serum OS levels were associated with higher New York Heart Association class (P = .01), worse renal function (serum urea, creatinine, and creatinine clearance) (P<.001) and higher serum levels of hs-C-reactive protein and N-terminal pro brain natriuretic peptide (P = .001, P<.001, respectively).
Conclusions: In chronic systolic HF patients, high serum OS levels correlate with advanced disease and known markers of poor prognosis.

Background: Numerous studies have demonstrated the significance of trimethylamine-N-oxide (TMAO) in the progression of atrial fibrillation (AF). However, the association between TMAO and AF recurrence (RAF) post-catheter ablation is not yet fully understood. This study aims to elucidate the predictive capability of pre-procedural TMAO levels in determining RAF following catheter ablation (CA).

This study investigated the effects of bamboo shoot extract (Bambusa vulgaris) as a feed additive on the health profiles and infection resistance of Nile tilapia (Oreochromis niloticus) against Pseudomonas putida. Bamboo shoot extract was added at levels of 0 g, 40 g, and 60 g per 1000 g of diet over a 60-day period. The fish were then challenged with a pathogenic P.

Background: Acute ischemia in the hind extremities is a dangerous disease that causes irreversible damage. Revascularization procedures are important to prevent muscle damage, but these treatments may induce additional damage, also known as ischemia-reperfusion injury. The role of free radicals as pivotal mediators of ischemia-reperfusion injury remains a prominent hypothesis.

Aminated carbon nanotubes, CNT, were covalently modified with glutardialdehyde (GDI) and the redox dye Azure to form a new electrode material CNT-GDI-Azure (CGA). The nanocomposite of CGA and polysaccharide chitosan was used for the anodic determination of NADH. Compared to conventional carbon and metal electrodes, the CGA electrode drastically lowered the overpotential for NADH oxidation (by > 0.

Background: Previous studies have demonstrated perfluoroalkyl and polyfluoroalkyl substances (PFAS) impact renal function, with albumin playing dominant role in their transport and accumulation. However, the mediating role of albumin in PFAS-induced renal impairment and the identification of sensitive populations remain uninvestigated.
Methods: This study included 9328 individuals from NHANES 1999-2018 with data on serum PFAS, creatinine, albumin, and covariates.
