Top-Down Mass Analysis of Protein Tyrosine Nitration: Comparison of Electron Capture Dissociation with “Slow-Heating” Tandem Mass Spectrometry Methods [PDF]

open access: yes, 2010
Tyrosine nitration in proteins is an important post-translational modification (PTM) linked to various pathological conditions. When multiple potential sites of nitration exist, tandem mass spectrometry (MS/MS) methods provide unique tools to locate the ...

Long-wavelength fluorescent boronate probes for the detection and intracellular imaging of peroxynitrite.

open access: yesChemical Communications, 2017
Two boronate fluorescent probes have been developed for the detection of peroxynitrite (TCFB1 and TCFB2). TCFB1 was shown to have a low sensitvity towards peroxynitrite and have a poor solubility in aqueous solution whereas TCFB2 demonstrated high ...

Pathological Disulfide Bond Crosslinking: Molecular Insights into Amyloidogenesis and Diseases Progression

open access: yesChemBioChem, EarlyView.
This review explores pathological disulfide‐crosslinking as a key driver of amyloidogenic protein misfolding and aggregation. Oxidative and ER stress pathways contributing to disease progression are discussed and emerging therapeutic strategies targeting disulfide‐linked aggregates in neurodegenerative and systemic amyloid diseases are examined ...

Living in an Oxygen Atmosphere – NO• Problem?

open access: yesCHIMIA, 2001
Formation of nitrogen monoxide in vivo as a signal molecule and as part of the immunological response leads to the formation of oxidized haemoproteins and a powerful oxidant, peroxynitrite.

Manganese Superoxide Dismutase Dysfunction and the Pathogenesis of Kidney Disease

open access: yesFrontiers in Physiology, 2020
The mitochondria are a major source of reactive oxygen species (ROS). Superoxide anion (O2•–) is produced by the process of oxidative phosphorylation associated with glucose, amino acid, and fatty acid metabolism, resulting in the production of adenosine

Metabolic syndrome influences cardiac gene expression pattern at the transcript level in male ZDF rats [PDF]

open access: yes, 2013
Background: Metabolic syndrome (coexisting visceral obesity, dyslipidemia, hyperglycemia, and hypertension) is a prominent risk factor for cardiovascular morbidity and mortality, however, its effect on cardiac gene expression pattern is unclear ...

Phase Equilibrium and Thermophysical Properties of Hydrochar–Metal Composites: In‐Depth Analysis and Application Prospects

open access: yesCleanMat, EarlyView.
Hydrochar–metal composites with adjustable structures exhibit improved thermal properties for applications like catalysis and energy storage. This review discusses their preparation, phase behavior, and thermal performance, emphasizing metal integration and hydrothermal methods. Challenges involve large‐scale production and phase modeling, while future

Boronate based fluorescence (ESIPT) probe for peroxynitrite.

open access: yesChemical Communications, 2016
A simple probe for the detection of peroxynitrite was developed incorporating a benzyl boronic ester "protecting" unit. The "protecting" unit of the probe is removed by peroxynitrite to "turn-on" ESIPT fluorescence (4.5 fold enhancement).

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1059-1080, April 2025.
Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...
