GhSTH-2 Integrates Host Redox Signalling and Effector Recognition and Confers Resistance Against Verticillium dahliae in Cotton. [PDF]

Mol Plant Pathol
The fungal effector VdEPG1, secreted by Verticillium dahliae, interacts with the PR10/Bet v1‐like protein GhSTH‐2. This interaction activates GhSTH‐2‐mediated enhancement of cotton disease resistance through GhTXNDC9‐dependent ROS signalling, while simultaneously enabling VdEPG1 to suppress GhSTH‐2‐induced immunogenic necroptosis.

An Optimized Staining Method for Visualization of Thermally Denatured Dermal Collagen. [PDF]

Lasers Surg Med
ABSTRACT Background and Objectives Accurate visualization of thermal damage zone (TDZ) in the dermis is critical for energy‐based device (EBD) and burn research. While nitroblue tetrazolium chloride (NBTC) staining and birefringence imaging are commonly used, both rely on detecting loss‐of‐signal, thereby only inferring TDZ indirectly.

Observações sobre o comportamento do teste do "nitroblue tetrazolium" relativamente à toxoplasmose adquirida, forma linfoglandular

Revista da Sociedade Brasileira de Medicina Tropical, 1974
O teste de "nitroblue tetrazolium", apesar de inespeclfico, tem-se mostrado útil no sentido de facilitar diagnóstico diferencial relativo a diversas afecções e, sobretudo, de indicar se determinado processo mórbido é presumivelmente bacteriano. Diante da

Manganese Superoxide Dismutase Activity Assay in the Yeast Saccharomyces cerevisiae

Bio-Protocol, 2020
Superoxide dismutases (SODs) act as a primary defence against reactive oxygen species (ROS) by converting superoxide anion radicals (O2-) into molecular oxygen (O2) and hydrogen peroxide (H2O2).

Cases of Impaired Oxidative Burst in HIV-Exposed Uninfected Infants’ Neutrophils—A Pilot Study

Frontiers in Immunology, 2017
An increased risk of serious bacterial infections in HIV-exposed uninfected (HEU) infants has been demonstrated. Although neutrophils are essential for the protection of infants against bacterial infections, no study has investigated their profile in HEU

STANDARDISATION OF THE NITROBLUE-TETRAZOLIUM TEST [PDF]

Journal of Medical Microbiology, 1975
Optimal conditions for the NBT-reduction test have been sought. Increasing heparin concentrations up to 100 units per ml and a delay in performance of the test, especially when blood specimens are kept at room temperature, resulted in higher values for the NBT index, which then sometimes exceeded the upper limit of normal in healthy people and in ...

Dihydroneopterin and the generation of superoxide from iron ions

Pteridines, 2000
We describe the impact of dihydroneopterin on the formation of superoxide radicals. As radical source ferrous iron in air-saturated aequeous solution was used.

Comprehensive evaluation of some phagocytosis parameters in children aged 2–5 years, depending on the incidence of acute respiratory infections

Zdorovʹe Rebenka, 2023
Background. After respiratory virus infection, there is an increased production of pro-inflammatory cytokines, inclu­ding tumor necrosis factor (TNF) α, interleukin (IL) 6, ­IL-1β that leads to cross-activation of the neuroendocrine immune system, which ...
