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

Journal 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 ...

Oral Health, Periodontitis, and Respiratory Diseases: Biological Pathways

Journal of Periodontal Research, EarlyView.
This narrative review aims to provide a comprehensive update on the potential mechanisms by which poor oral health and periodontitis impact lung health, focusing on pneumonia, COPD, and asthma. ABSTRACT Poor oral hygiene and periodontitis influence lung diseases such as pneumonia, chronic obstructive pulmonary disease (COPD), COVID‐19, and asthma.

Ecological and genomic variation in ectomycorrhizal fungal exploration types

New Phytologist, EarlyView.
Summary Ectomycorrhizal fungi (EMF) produce mycelia with variable extension and complexity, which can be classified according to soil ‘exploration types’ (ETs). ETs have received attention as one of the few mycorrhizal trait frameworks, but without an empirical classification of ET functional diversity and environmental preferences, understanding and ...

Immunocytochemical Localization of Nitrite Reductase in Green Algae

Plant Physiology, 1991
The distribution of nitrite reductase (EC 1.7.7.1) in the green algae Chlamydomonas reinhardtii, Monoraphidium braunii, Chlorella fusca, and Scenedesmus obliquus was studied by immunoelectron microscopy. The labeling of ultrathin cryosections was performed with anti-nitrite reductase antibodies followed by gold-labeled goat anti-rabbit antibodies. In C.

The ComEA/ComEC Operon is Critical for Nitrosative Stress Tolerance by an Oral Commensal

Molecular Oral Microbiology, EarlyView.
ABSTRACT Oral commensal streptococci play a large role in mediating microbial homeostasis. Our prior work has demonstrated that hydrogen peroxide (H2O2) produced by oral commensal streptococci can react with salivary nitrite (NO2) and generate peroxynitrite (ONOO−), a potent antimicrobial.

A QM/MM Study of Nitrite Binding Modes in a Three-Domain Heme-Cu Nitrite Reductase

Molecules, 2018
Copper-containing nitrite reductases (CuNiRs) play a key role in the global nitrogen cycle by reducing nitrite (NO2−) to nitric oxide, a reaction that involves one electron and two protons.

Effects of dietary nitrate supplementation on peak oxygen uptake following 10 days of Ramadan fasting in healthy adults

Experimental Physiology, EarlyView.
Abstract Ramadan is a sacred religious practice observed by Muslims that involves abstaining from food and water from sunrise to sunset for 1 month. Prior work has reported that peak oxygen uptake (V̇O2peak${{\dot{V}}_{{{{\mathrm{O}}}_2}{\mathrm{peak}}}}$) can decline during Ramadan in parallel with reduced physical activity.

Born early, age fast: Consequences of premature birth on chronic disease and accelerated ageing

The Journal of Physiology, EarlyView.
Abstract figure legend ELGANs are exposed to several postnatal pro‐oxidant stressors, including ambient and supplemental oxygen, mechanical ventilation, infections, hyperalimentation, excessive glucocorticoids and intermittent hypoxia. Since endogenous antioxidant defences are underdeveloped, this imbalance promotes oxidative stress and inflammation ...

Analysis of Microbial Diversity Dominating Nitrite Enzymatic Degradation and Acidic Degradation in the Fermentation Broth of Northeast Sauerkraut

Foods
Nitrite hazard is an important food safety issue in the production process of Chinese Northeastern sauerkraut, but this nitrite can be eliminated through microbial enzymatic degradation and acidic degradation as fermentation progresses.

Calcium, methyl jasmonate and their combined foliar applications: Influence on Tempranillo grape amino acids composition over two seasons

Journal of the Science of Food and Agriculture, Volume 106, Issue 12, Page 7380-7396, September 2026.
Abstract BACKGROUND Climate change is currently affecting chemical grape composition and, consequently, grape quality. The foliar application of biostimulants has emerged as a promising approach to mitigate these effects. This study investigated the effects of foliar applications of calcium (Ca), methyl jasmonate (MeJ), and their combination (Ca + MeJ)
