Acute freshwater CO2 exposure does not impair seawater transfer in three different sizes of Atlantic salmon (Salmo salar) subjected to different photoperiod manipulations

Journal of Fish Biology, EarlyView.
Abstract There is a growing interest in Atlantic salmon (Salmo salar) aquaculture to extend the time fish are reared in freshwater (FW) recirculating aquaculture systems (RAS), producing larger FW salmon that can then be induced to undergo smoltification before transfer into marine net pens for grow‐out and harvest.

Methemoglobin formation by nitrite ion in the hemolysates of normal and acatalasemic mice [PDF]

, 1987
The formation of methemoglobin from hemoglobin in the hemolysates of normal and acatalasemic mice was studied by addition of nitrite ion in the range from 0.99-2.60 mM.

Differential intestinal injury and unchanged systemic inflammatory responses to leg and whole‐body passive hyperthermia in healthy humans

Experimental Physiology, EarlyView.
Abstract Hyperthermia can cause intestinal injury, facilitating endotoxin translocation and an inflammatory response that has been associated with heat illness. However, the potential occurrence of these responses has been incompletely reported during passive hyperthermia, and the independent effect of hyperthermia is equivocal.

Increases in skin perfusion and blood oxygen in the non‐exercising human limbs during exercise in the heat: Implications for control of circulation

Experimental Physiology, EarlyView.
Abstract Blood flow in the inactive limb tissues and skin is widely thought to decline during incremental exercise to exhaustion due to augmented sympathoadrenal vasoconstrictor activity, but direct evidence to support this view is lacking. Here, we investigated the inactive‐forearm haemodynamic (Q̇forearm${\dot{Q}}_{\mathrm{forearm}}$) and oxygenation

AAPH-induced oxidative damage reduced anion exchanger 1 (SLC4A1/AE1) activity in human red blood cells: protective effect of an anthocyanin-rich extract

Frontiers in Physiology, 2023
Introduction: During their lifespan in the bloodstream, red blood cells (RBCs) are exposed to multiple stressors, including increased oxidative stress, which can affect their morphology and function, thereby contributing to disease.Aim: This ...

Biomimetic Hydrogel System Targeting S100A8 Centered Neuroimmune Crosstalk and Hypoxia Induced Neuronal Injury

Advanced Science, Volume 13, Issue 52, 18 September 2026.
A biomimetic hydrogel (HPC@Gel) was developed for traumatic brain injury repair by combining oxygen‐carrying hemoglobin nanoparticles and anti‐inflammatory carbon quantum dots within a brain‐like matrix. The system alleviated hypoxia, reduced harmful neuroimmune signaling, protected neurons, supported neural regeneration, and improved neurological and ...

DAMPs, PAMPs, and Alarmins: From Mechanism to Therapy

MedComm, Volume 7, Issue 9, September 2026.
This review synthesizes the expanding biology of PAMPs and DAMPs, from their molecular sources and sensing mechanisms to regulatory networks that govern inflammation and homeostasis. Spanning from classical immune activation to trained immunity and interorgan communication, we highlight the interplay between PAMPs and DAMPs and their context‐dependent ...

Peroxynitrite‐induced structural remodeling and aggregation of hemoglobin under nitroxidative stress

Protein Science, Volume 35, Issue 9, September 2026.
Abstract Peroxynitrite (PN), generated by the reaction of nitric oxide with superoxide, is a potent reactive nitrogen species (RNS) implicated in nitroxidative protein damage in cardiovascular and neurodegenerative diseases. Hemoglobin (Hb), the principal oxygen‐transport protein of erythrocytes, is a key intravascular scavenger and target of PN ...

Prilocaine-Induced Methemoglobinemia During Surgically Assisted Rapid Palatal Expansion (SARPE) Under General Anesthesia: A Case Report

Case Reports in Dentistry
Methemoglobinemia is a condition in which methemoglobin levels in the blood increase. Methemoglobin lacks oxygen-binding ability, resulting in oxygen deprivation in tissues.

1,4-diaminobenzene and diphenylamine-induced severe methemoglobinaemia treated by hyperbaric oxygen therapy – Case report

Medycyna Pracy, 2018
Methemoglobin is an oxidized form of hemoglobin that is not capable of carrying oxygen. Exposure to exogenous oxidizing agents can cause severe methemoglobinemia and subsequent hypoxia.
