Methaemoglobinaemia: From pathophysiology to contemporary clinical management
Summary Methaemoglobin (MetHb) is an oxidised form of haemoglobin (Hb) unable to bind oxygen. Raised levels of MetHb reduce the blood's oxygen‐carrying capacity, causing potentially severe hypoxaemia and possible death. The condition arises from three main pathologies: mutations in globin genes causing Haemoglobin‐M, inherited deficiency of the enzyme ...

Background and Purpose Sickle cell disease (SCD) is a hereditary blood disorder caused by mutation of β‐globin. In SCD, haemoglobin polymerization causes red blood cells to assume a rigid sickle‐shape leading to neurovascular alterations, including development of vascular dementia – characterized by cognitive impairment and reduced cerebral perfusion ...

Elesclomol‐induced cuproptosis potently activates both innate and adaptive antitumor immunity, especially CD8+ T cell immunity. FDX1 serves as a central regulator of CD8+ T cell functionality through DMBT1 downregulation during cuproptosis in colorectal cancer.

Small protein MtrR is a regulator of the Mtr methyltransferase complex in Methanosarcina mazei. It binds specifically to the MtrA subunit and modulates Mtr activity in response to hydrogen (H2) availability. Deleting mtrR impairs growth in the presence but not absence of H2, indicating its role in directing methyl transfer toward an energy‐conserving ...

Pyridoxal 5′‐phosphate (PLP) homeostasis relies on salvage enzymes, yet key metabolic branches remain undefined. We identify AKR1C isozymes as previously undescribed contributors that convert pyridoxal into pyridoxine or 4‐pyridoxolactone through reductase and dehydrogenase activities.

Prebiotic aqueous reactions catalyzed by native nickel without hydrogen
Serpentinizing (H2‐producing) hydrothermal vents are candidate environments for metabolic origin. They generate highly reducing conditions that convert CO2 to formate and methane in abiotic reactions resembling reactions of the acetyl‐CoA pathway of CO2 fixation. They also contain natural catalysts. Native nickel (Ni0), like Fe0, Co0, and their alloys,
