Adding ROS Scavengers to Cold K\u3csup\u3e+\u3c/sup\u3e Cardioplegia Reduces Superoxide Emission During 2 h Global Cold Cardiac Ischemia [PDF]

open access: yes, 2012
We reported that the combination of reactive oxygen species (ROS) quenchers Mn(III) tetrakis (4-benzoic acid) porphyrin (MnTBAP), catalase, and glutathione (MCG) given before 2 hours cold ischemia better protected cardiac mitochondria against cold ...

Wave Mechanics of Ciliary Proteins: Quantum‐Enabled Sensing and Energy Transfer in the “Cellular Antenna”

open access: yesAggregate, Volume 7, Issue 6, June 2026.
This review surveys eukaryotic cilia as putative quantum‐enabled sensory and regulatory centers. It highlights their multifaceted roles in the cell, focuses on the nontrivial roles of quantum mechanics in their membrane and cytoskeletal proteins, and introduces the essential building blocks enabling quantum properties to survive in the warm, wet, and ...

High doses of riboflavin and the elimination of dietary red meat promote the recovery of some motor functions in Parkinson's disease patients

open access: yesBrazilian Journal of Medical and Biological Research, 2003
Abnormal riboflavin status in the absence of a dietary deficiency was detected in 31 consecutive outpatients with Parkinson's disease (PD), while the classical determinants of homocysteine levels (B6, folic acid, and B12) were usually within normal ...

Refractive Index Spectral Fingerprints of Pathogenic Bacteria Revealed by Monte Carlo‐Optimized Opto‐Microfluidic Extinction Spectroscopy

open access: yesJournal of Biophotonics, Volume 19, Issue 6, June 2026.
A physics‐informed opto‐microfluidic platform reconstructs refractive index spectra of pathogenic bacteria through Monte Carlo‐based inverse modeling. These optical fingerprints enable label‐free species identification with 97.75% accuracy using a one‐dimensional convolutional neural network, demonstrating a scalable biophotonic strategy for rapid ...

Regulation of the mechanism of Type-II NADH: Quinone oxidoreductase from S. aureus

open access: yesRedox Biology, 2018
Type-II NADH:quinone oxidoreductases (NDH-2s) are membrane proteins involved in respiratory chains and the only enzymes with NADH:quinone oxidoreductase activity expressed in Staphylococcus aureus (S.

Oxidative Stress and DNA Epigenetic Modifications in Cancer: Mechanisms and Targeted Therapeutics

open access: yesMedComm – Oncology, Volume 5, Issue 2, June 2026.
Reactive oxygen species (ROS) modulate DNA methyltransferases (DNMTs), ten‐eleven translocation family proteins (TETs) and their cofactors, reshaping 5‐methylcytosine (5mC)/5‐hydroxymethylcytosine (5hmC)/5‐formylcytosine (5fC) landscapes and gene expression in cancer cells. In turn, epigenetic control of antioxidant and metabolic pathways feeds back on

Cannabidiol and cannabigerol ameliorate steatotic liver disease via phosphocreatine buffering and lysosomal restoration

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 12, Page 3173-3194, June 2026.
Cannabidiol (CBD) and cannabigerol (CBG) alleviate hepatic steatosis in obese mice by shifting energy buffering towards phosphocreatine and enhancing lysosomal lipid degradation and trafficking. These effects are associated with increased creatine kinase activity and lysobisphosphatidic acid (LBPA) levels, highlighting a previously unrecognised ...
