The Sarcoplasmic/Endoplasmic reticulum Ca<sup>2+</sup>-ATPase (SERCA) is present in pig sperm and modulates their physiology over liquid preservation. [PDF]
Sci RepLiquid storage is the primary preservation method in the swine breeding industry because of its advantages over cryopreservation. Calcium (Ca2+), a key regulator of cell physiology, plays a crucial role during liquid preservation.

Radical pairs and superoxide amplification can explain magnetic field effects on planarian regeneration [PDF]
arXiv, 2023 Weak magnetic field exposure can affect many biological processes across a wide range of living organisms. Recently, it has been observed that weak magnetic fields can modulate reactive oxygen species (ROS) concentration, affecting regeneration in planaria.

Pulse radiolysis studies on superoxide reductase from Treponema pallidum [PDF]
FEBS Letters, Elsevier, 2001, 497, pp.171-3, 2015 Superoxide reductases (SORs) are small metalloenzymes, which catalyze reduction of O2*- to H2O2. The reaction of the enzyme from Treponema pallidum with superoxide was studied by pulse radiolysis methods. The first step is an extremely fast bi-molecular reaction of the ferrous center with O2, with a rate constant of 6 x 10 (8) M(-1) s(-1).

Structure of superoxide reductase bound to ferrocyanide and active site expansion upon X-ray-induced photo-reduction [PDF]
Structure, 2004, 12, pp.1729-40, 2015 Some sulfate-reducing and microaerophilic bacteria rely on the enzyme superoxide reductase (SOR) to eliminate the toxic superoxide anion radical (O2*-). SOR catalyses the one-electron reduction of O2*- to hydrogen peroxide at a nonheme ferrous iron center. The structures of Desulfoarculus baarsii SOR (mutant E47A) alone and in complex with ferrocyanide
