Possibilities of the use of fast scan voltammetry in simultaneous determination of purines at carbon fiber ultramicroelectrodes

Journal of the Brazilian Chemical Society, 2000
Hypoxanthine, xanthine and uric acid are purines present in extracellular fluids that can be used as metabolic markers, in evaluation of meat conservation and other applications. Voltammetric studies were performed in order to investigate the possibility

Abnormal early cleavage events predict early embryo demise: sperm oxidative stress and early abnormal cleavage. [PDF]

, 2014
Human embryos resulting from abnormal early cleavage can result in aneuploidy and failure to develop normally to the blastocyst stage. The nature of paternal influence on early embryo development has not been directly demonstrated although many studies ...

Finerenone, chronic obstructive pulmonary disease, and heart failure with mildly reduced or preserved ejection fraction: A prespecified analysis of the FINEARTS‐HF trial

European Journal of Heart Failure, EarlyView.
The beneficial effects of finerenone in patients with heart failure (HF) and mildly reduced or preserved ejection fraction were consistent, regardless of a history of chronic obstructive pulmonary disease (COPD) status. BMI, body mass index; LVEF, left ventricular ejection fraction; NT‐proBNP, N‐terminal pro‐B‐type natriuretic peptide.

7-Keto-Cholesterol and Cholestan-3beta, 5alpha, 6beta-Triol Induce Eryptosis through Distinct Pathways Leading to NADPH Oxidase and Nitric Oxide Synthase Activation [PDF]

, 2019
BACKGROUND/AIMS: We showed that patho-physiological concentrations of either 7-keto-cholesterol (7-KC), or cholestane-3beta, 5alpha, 6beta-triol (TRIOL) caused the eryptotic death of human red blood cells (RBC), strictly dependent on the early production

Mechanical unloading is accompanied by reverse metabolic remodelling in the failing heart: Identification of a novel citraconate‐mediated pathway

European Journal of Heart Failure, EarlyView.
Aims Although functional recovery of the failing heart with left ventricular assist device (LVAD) unloading can occur, the underpinning mechanism is unclear. We aimed to characterize the effect of myocardial biochemical effect of LVAD support in vivo and in vitro.

Xanthine urolithiasis.

Saudi journal of kidney diseases and transplantation : an official publication of the Saudi Center for Organ Transplantation, Saudi Arabia, 2010
Hereditary xanthinuria type I, a defect of purine metabolism, results from a genetic deficiency of xanthine oxidase. It is an uncommon cause of stone formation in children. We report here two children with xanthine urolithiasis. The first patient was an 8-year-old boy who presented with repeated episodes of hematuria evaluated with excretory urography,

Sacubitril/valsartan reduces serum uric acid concentration, an independent predictor of adverse outcomes in PARADIGM-HF [PDF]

, 2017
Aims: Elevated serum uric acid concentration (SUA) has been associated with an increased risk of cardiovascular disease, but this may be due to unmeasured confounders.

Interpretation of in vitro concentration‐response data for risk assessment and regulatory decision‐making: Report from the 2022 IWGT quantitative analysis expert working group meeting

Environmental and Molecular Mutagenesis, EarlyView.
Abstract Quantitative risk assessments of chemicals are routinely performed using in vivo data from rodents; however, there is growing recognition that non‐animal approaches can be human‐relevant alternatives. There is an urgent need to build confidence in non‐animal alternatives given the international support to reduce the use of animals in toxicity ...

Lipid peroxidation is a nonparenchymal cell event with reperfusion after prolonged liver ischemia [PDF]

, 1990
A proposed mechanism for irreversible ischemic liver damage has been peroxidation of membrane phospholipids by free radicals. However, the hepatocyte is laden with enzymes which are antioxidants and, therefore, ought to be relatively resistant to ...

Inherited metabolic epilepsies–established diseases, new approaches

Epilepsia Open, EarlyView.
Abstract Inherited metabolic epilepsies (IMEs) represent the inherited metabolic disorders (IMDs) in which epilepsy is a prevailing component, often determining other neurodevelopmental outcomes associated with the disorder. The different metabolic pathways affected by individual IMEs are the basis of their rarity and heterogeneity.
