The key role of nitric oxide in hypoxia: hypoxic vasodilation and energy supply-demand matching [PDF]

open access: yes, 2013
Significance: a mismatch between energy supply and demand induces tissue hypoxia with the potential to cause cell death and organ failure. Whenever arterial oxygen concentration is reduced, increases in blood flow - 'hypoxic vasodilation' - occur in an ...

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Autoimmunity and Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
In a microbe‐driven inflammatory environment, peptidyl‐arginine deiminase (PAD) enzymes from neutrophils and Porphyromonas gingivalis citrullinate both microbial and self‐antigens. B cell presentation of citrullinated or self‐mimicking epitopes activates T cells that assist B cells in antibody isotype switching, affinity maturation, epitope spreading ...

The effect of endurance resistance exercise combined with L­citrulline malate supplement on FGF, VEGF, and fatigue among young bodybuilders [PDF]

open access: yesفصلنامه ابن سینا, 2019
Background: Citrulline malate is a non-essential alpha-amino acid supplement resulting from arginine oxidation and may cause changes in the immunity, cardiovascular, and angiogenic mechanisms. It also reduces the rating of fatigue perception. The purpose

Mitokondriális eredetű nitrogén szabadgyökök és ATP-függő K-csatornák szerepe az organellum működésében = The involvement of mitochondrial-derived nitrogen radicals and mitoK-ATP channels in the regulation of organelle function [PDF]

open access: yes, 2009
Elsőként a mitoKATP csatornák alegységeit terveztük azonosítani humán szív mintákon. A kísérletek során megbizonyosodtunk afelől, hogy a korábban ilyen csatornáknak gondolt fehérjék nincsenek jelen megfelelő számban és formában a mitokondriális ...

Ornithine decarboxylase activity, a clinical biomarker for evaluating cancer chemopreventive efficacy of phytomolecules [PDF]

open access: yes, 2011
Biomarkers of cancer have made a strong traipse in predicting the disease pattern and contributed significantly to the understanding of tumour state, progression, characteristics and response to therapies.

Autoantibodies to citrullinated proteins: ACPA

open access: yesAutoimmunity, 2005
Anti-perinuclear factor and anti-keratin antibodies have long been known to be specifically associated with rheumatoid arthritis (RA). They were first demonstrated to target various forms of (pro)filaggrin, a protein of stratified epithelia. Then, they were found to belong to a single family of autoantibodies targeting proteins that bear peptidic ...

Pinus‐derived membrane vesicles disrupt pathogenic metabolism in fungi

open access: yesPlant Biology, EarlyView.
Needle‐derived vesicles from pine trees impair fungal metabolism and growth, offering a sustainable strategy to control pine pitch canker disease. Abstract Much of what we know about the biological impacts of vesicles (MVs) is derived from Arabidopsis thaliana.

Chitosan-coated nanoliposomes as vehicles for l-citrulline: Preparation, characterization, antioxidant properties, and nanovesicles behavior

open access: yesCarbohydrate Polymer Technologies and Applications
L-Citrulline is classified as a non-essential amino acid that plays a role in the nitric oxide system in humans. It offers potential antioxidant benefits and may aid in promoting vasodilation.

Minimal ureagenesis is necessary for survival in the murine model of hyperargininemia treated by AAV-based gene therapy. [PDF]

open access: yes, 2014
Hyperammonemia is less severe in arginase 1 deficiency compared with other urea cycle defects. Affected patients manifest hyperargininemia and infrequent episodes of hyperammonemia. Patients typically suffer from neurological impairment with cortical and
