Published: January 2021

Despite the exhaustive search for an acceptable substitute to erythrocyte transfusion, neither chemical-based products such as perfluorocarbons nor hemoglobin-based oxygen carriers have succeeded in providing a reasonable alternative to allogeneic blood transfusion. However, there remain scenarios in which blood transfusion is not an option, due to patient's religious beliefs, inability to find adequately cross-matched erythrocytes, or in remote locations. In these situations, artificial oxygen carriers may provide a mortality benefit for patients with severe, life-threatening anemia. This article provides an up-to-date review of the history and development, clinical trials, new technology, and current standing of artificial oxygen carriers as an alternative to transfusion when blood is not an option.

The natural extracellular hemoglobin of the lugworm Arenicola marina (AmHb) has many interesting characteristics: It carries 40 times more oxygen than human hemoglobin; has anti-inflammatory, antibacterial, and antioxidant properties; and is 250 times smaller than a red blood cell. It is nontoxic and nonimmunogenic. It is thus a very promising hemoglobin-based oxygen carrier.

The Mediterranean diet is a well-known dietary pattern that has gained considerable popularity worldwide for its ability to prevent the progression of nonalcoholic fatty liver disease. This is largely attributed to the use of virgin olive oil as the primary source of fat, which contains a substantial amount of squalene, a natural antioxidant. In order to enhance the delivery of squalene and amplify its effects due to its highly hydrophobic nature, herein, squalene has been incorporated into chitosan nanoparticles.

Inflammatory Pathways of Sulfonamide Diuretics: Insights into SLC12A Cl Symporters and Additional Targets.

Cell Physiol Biochem

January 2025

Department of Pharmacology and Toxicology, Wright State University, School of Medicine. Dayton, Ohio, United States,

Thiazide, thiazide-like, and loop diuretics are primarily known for inhibiting members of the SLC12A family of Cl transporters, which include the Na+Cl cotransporter (NCC), NaK2Cl cotransporters (NKCC1 and NKCC2) and KCl symporters (KCC1-4). While the main pharmacological effect of these diuretics is diuresis, achieved by promoting the excretion of excess water and salt through the kidneys, they have intriguing pharmacological effects beyond their traditional ones which cannot be solely attributed to their effects on renal salt transport. Of particular interest is their role in modulating inflammatory processes.

Solute carrier family 23 (SLC23) mediates cellular uptake of ascorbic acid, a crucial antioxidant protecting organisms against oxidative stress. Despite advances in understanding SLC23 in mammals, its physiological roles in bivalves remain poorly understood. Notably, euryhaline bivalves exhibit a significant expansion and positive selection of SLC23, highlighting the need for deeper investigation.

Electroacupuncture attenuates ferroptosis by promoting Nrf2 nuclear translocation and activating Nrf2/SLC7A11/GPX4 pathway in ischemic stroke.

Objective: Electroacupuncture has been shown to play a neuroprotective role following ischemic stroke, but the underlying mechanism remains poorly understood. Ferroptosis has been shown to play a key role in the injury process. In the present study, we wanted to explore whether electroacupuncture could inhibit ferroptosis by promoting nuclear factor erythroid-2-related factor 2 (Nrf2) nuclear translocation.
