Transgenic selection and underlying mechanisms in apicomplexan parasites

open access: yesThe FEBS Journal, EarlyView.
Transgenic selection markers have driven genetic engineering in apicomplexans, enabling precise, iterative experiments. This review discusses mechanistic details of drug selection markers, strategies for marker recycling, and practical considerations for several clinically relevant parasites.

The Role of Xanthine Oxidase in Pregnancy Complications: A Systematic Review

open access: yesAntioxidants
Xanthine oxidoreductase (XOR) is an enzyme involved in the oxidation of hypoxanthine and xanthine to uric acid. XOR has two isoforms: xanthine dehydrogenase and xanthine oxidase (XO).

Xanthine Oxidase and Xanthine Dehydrogenase from an Estivating Land Snail

open access: yesZeitschrift für Naturforschung C, 1995
Abstract During arousal from estivation in land snails. Otala lactea, active metabolic functions are restored within minutes and oxygen consumption increases dramatically. During the transition from the hypoxic conditions of estivation to normoxia it is possible that xanthine oxidase (XO ) in hepatopancreas contributes to the observed ...

Evolutionary Conserved and Divergent Responses to Copper Zinc Superoxide Dismutase Inhibition in Plants

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT After an initial evolution in a reducing environment, life got successively challenged by reactive oxygen species (ROS), especially during the great oxidation event (GOE) that followed the development of photosynthesis. Therefore, ROS are deeply intertwined into the physiological, morphological and transcriptional responses of most present‐day

Novel Amino Acid Changes Increase Phosphoenolpyruvate Carboxylase Output in planta

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Characterization of previously reported Arabidopsis mutants with increased aluminum (Al) resistance (alr) resulting from greater release of Al‐chelating malate identified three unique amino acid substitutions that each impacts PHOSPHOENOLPYRUVATE CARBOXYLASE 1, a key anaplerotic carbon fixation enzyme.

First case of hereditary xanthinuria in a Moroccan family

open access: yesPAMJ Clinical Medicine, 2019
The xanthinuria is a rare hereditary autosomal recessive disease. It is related to xanthine oxidase deficiency also known as xanthine dehydrogenase, an enzyme involved in the metabolism of purine bases.

Effects of cold water immersion versus active recovery on oxidative stress, redox gene expression and mitochondrial adaptations after strength training

open access: yesExperimental Physiology, EarlyView.
Abstract We compared the acute and chronic effects of postexercise cold water immersion (CWI) and active recovery (ACT) on oxidative stress, redox‐related gene expression, mitochondrial adaptations and muscle oxidative capacity. In a crossover study, nine males completed strength sessions, followed by either 10 min CWI or ACT.

Mitochondrial oxidative stress, calcium and dynamics in cardiac ischaemia‐reperfusion injury

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Heart attack causes ischaemia–reperfusion injury in cardiomyocytes. Mitochondria generate reactive oxygen species (ROS), leading to oxidative stress. High levels of mitochondrial calcium (Ca2+) activate the mitochondrial permeability transition pore (mPTP), and excess ROS levels can lower the Ca2+ required to activate the mPTP ...

Intelligent design of artificial biocatalyst for biomedical diseases

open access: yesJournal of Intelligent Medicine, Volume 3, Issue 3, Page 220-249, September 2026.
This review summarizes recent advances in the intelligent design of artificial biocatalysts for biomedical diseases. By leveraging tailored design strategies, including environment‐responsive engineering and rational/artificial intelligence‐aided optimization, these biocatalysts enable precise modulation of pathological microenvironments and targeted ...

Oxidative and Antioxidant Systems in Ferroptosis of Cancer: Mechanisms, Regulations, and Therapeutic Targeting

open access: yesMedComm – Oncology, Volume 5, Issue 3, September 2026.
Ferroptosis is governed by the balance between reactive oxygen species (ROS)‐driven lipid peroxidation and a multi‐tiered antioxidant network. ROS sources include mitochondrial electron transport chain, voltage‐dependent anion channels, NADPH oxidases, and endoplasmic reticulum‐resident oxidoreductases, while antioxidant defenses span the primary GSH ...
