Mitochondrial Ca2+ uniporter haploinsufficiency leads to sexually dimorphic redox imbalance and metabolic remodelling in the mouse brain

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The genetic inactivation of one Mcu allele leads to sex‐specific changes in neuronal function in adult mice, that is, the firing of action potentials and the relationship between cytosolic and mitochondrial Ca2+ levels. The ability to produce NAD(P)H by stimulated neural tissue is largely preserved in male mice but delayed in ...

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 ...

Extending Cofactor‐Tethered Nanomachines to Complex Multienzyme Redox Cascades in Continuous Flow

open access: yesChemSusChem, Volume 19, Issue 15, 14 August 2026.
Engineered enzyme fusions bearing covalently tethered PEG–nicotinamide cofactors enable intramolecular cofactor retention and recycling within self‐sufficient biocatalytic nanomachines. These nanomachines support cofactor‐autonomous operation of complex redox multienzyme cascades under continuous‐flow conditions, as demonstrated in a 10‐step glucose‐to‐

Biocatalytic Application of Goodfellowiella coeruleoviolacea Imine Reductase: Enantioselective Synthesis of Cyclic Secondary Amines in Deep Eutectic Solvent‐Based Media

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 15, 1 August 2026.
A Goodfellowiella coeruleoviolacea Imine Reductase is here reported as a novel enzyme for biocatalytic application in chiral amine synthesis. Deep eutectic solvents have been used to increase substrate loadings, up to 150 mM, and boost enzymatic activity. Reaction scope and scale‐up procedure showcased the protocol applicability.

Overcoming Radiation Resistance: Ferroptosis Induction to Sensitize Solid Tumors to Radiation Therapy

open access: yesCancer Medicine, Volume 15, Issue 8, August 2026.
ABSTRACT Radiation therapy (RT) is a mainstay of treatment for a myriad of cancers, often utilized for tumors that are unable to be resected, as well as an adjunct to surgery and chemotherapy. Unfortunately, many cancers are resistant to RT‐induced damage and subsequent cell death.

Phytochemical Composition, In Vitro Antioxidant, Antibacterial, and Antibiofilm Activities of Thymus vulgaris Essential Oil From Tiaret, Algeria

open access: yesChemistry &Biodiversity, Volume 23, Issue 8, August 2026.
Thymus vulgaris essential oil (TvEO), largely composed of thymol, showed strong bactericidal activity with Staphylococcus aureus (S. aureus) being most sensitive. TvEO markedly inhibited MRSA biofilm formation and significantly reduced established biofilms. Molecular docking suggests several TvEO components interact with proteins involved in S.

Beyond Tradition: An Integrated Toxicological, Ecological, and Public Health Perspective on Aristolochic Acids

open access: yesJournal of Applied Toxicology, Volume 46, Issue 8, Page 2599-2622, August 2026.
ABSTRACT Aristolochia species have long been used in traditional medicine for their presumed anti‐inflammatory, analgesic and antimicrobial properties. However, extensive toxicological and epidemiological evidence now demonstrates that these plants contain aristolochic acids (AAs) I and II, highly potent nephrotoxic, genotoxic, and carcinogenic ...

SRM 1650b Administration to Isolated Rat Heart Aggravates Ischemia‐Reperfusion Injury via Mitochondrial Dysfunction and Downregulation of PI3K/Akt Signaling Pathways

open access: yesJournal of Biochemical and Molecular Toxicology, Volume 40, Issue 8, August 2026.
SRM 1650b diesel particulate matter caused dose‐dependent cardiotoxicity in isolated male Wistar rat hearts, worsening hemodynamics and tissue injury after ischemia–reperfusion. It increased oxidative stress, impaired mitochondrial bioenergetics and respiration, downregulated mitochondrial quality‐control genes, reduced mtDNA copy number, and ...

Obstructive Sleep Apnea: Epidemiology, Pathophysiology, Complications, Diagnosis, Management, and Emerging Fibrosis‐Linked Remodeling

open access: yesMedComm, Volume 7, Issue 8, August 2026.
Obstructive sleep apnea (OSA) is characterized by recurrent upper‐airway collapse, which generates key nocturnal stressors including intermittent hypoxia, sleep fragmentation, intrathoracic pressure stress, and sympathetic activation. These physiological disturbances converge on shared biological mechanisms, including oxidative stress, inflammation ...
