Oxidative Stress and Risk of Dementia in Older Patients with Depression: A Longitudinal Cohort Study Using Plasma Biomarkers

open access: yesMedicina
Background and Objectives: While depression is associated with an increased risk of Alzheimer’s dementia (AD), traditional AD-related biomarkers, such as amyloid-beta, have shown limited predictive value for late-life depression.

Long‐Term Salt Exposure Reprograms the Nicotiana tabacum BY‐2 Suspension Proteome and Metabolome Toward Stabilization of the Core Metabolic Pathways, Protein Turnover Machinery Modifications, and Protective Metabolome Adjustments

open access: yesPlant, Cell &Environment, Volume 49, Issue 8, Page 5849-5865, August 2026.
ABSTRACT In this study, we analyzed a unique Nicotiana tabacum BY‐2 line that was gradually adapted to and subsequently maintained in 190 mM NaCl for over 15 years. Years of continuous high salinity shaped a stable “new homeostasis” in BY‐2 suspension cells. Salt‐adapted cells were smaller and formed tighter clusters. Metabolomics revealed constitutive

What nitrates tyrosine? Is nitrotyrosine specific as a biomarker of peroxynitrite formation in vivo? [PDF]

open access: yes, 1997
Peroxynitrite (ONOO−) is a `reactive nitrogen species' that can be formed (among other reactions) by combination of superoxide (O2·−) and nitric oxide (NO·) radicals.

Indicators of nitrosative and oxidative stress as non-invasive markers of bacterial meningitis in preterm infants

open access: yesZdorovʹe Rebenka, 2019
Background. In oxidative and nitrosative stresses, the brain is vulnerable to oxidant damage due to high oxygen consumption, large amounts of iron, relatively low antioxidant expression, high concentration of polyunsaturated fatty acids.

iNitro-Tyr: prediction of nitrotyrosine sites in proteins with general pseudo amino acid composition. [PDF]

open access: yesPLoS ONE, 2014
Nitrotyrosine is one of the post-translational modifications (PTMs) in proteins that occurs when their tyrosine residue is nitrated. Compared with healthy people, a remarkably increased level of nitrotyrosine is detected in those suffering from ...

Targeting Temozolomide‐Resistant Glioblastoma: Therapeutic Potential of Neuronal Nitric Oxide Synthase Inhibitor

open access: yesCancer Medicine, Volume 15, Issue 7, July 2026.
ABSTRACT Background and Purpose The treatment of glioblastoma remains a major clinical challenge, largely due to intrinsic and acquired resistance to Temozolomide (TMZ). We aim to advance a novel therapeutic approach to overcome TMZ resistance in human glioblastoma by using the neuronal nitric oxide synthase inhibitor BA‐101 as both a monotherapy and ...

Serum lipids and cardiac function correlate with nitrotyrosine and MMP activity in coronary artery disease patients. [PDF]

open access: yes, 2015
AIMS Peroxynitrite-matrix metalloproteinase (MMP) signalling has been shown to contribute to myocardial ischaemia/reperfusion injury and heart failure and to be influenced by hyperlipidaemia in preclinical models.

Immune Dysregulation in Branched Chain Organic Acidemias

open access: yesJournal of Inherited Metabolic Disease, Volume 49, Issue 4, July 2026.
ABSTRACT Organic acidemias (OAs) are a group of inherited disorders, most commonly caused by defects in mitochondrial enzymes involved in amino acid and fatty acid metabolism. While they characteristically present with metabolic and neurological crises, growing evidence reveals a significant burden of chronic immune dysregulation in some disorders and ...

Analysis of peptides and proteins containing nitrotyrosine by matrix-assisted laser desorption/ionization mass spectrometry [PDF]

open access: yes, 2001
Oxidative damage to proteins can occur under physiological conditions through the action of reactive oxygen species, including those containing nitrogen such as peroxynitrite (ONO2−).
