The player can choose from several locations to build a base, then reinforce and improve it with various facilities like watchtowers, gardens, sleeping quarters, kitchens, workshops, medical bays, etc. to help keep survivors safe and healthy. Part of the game is balancing the use of resources: food, medicine, ammo, and construction materials.
Superoxide dismutase 2, mitochondrial (SOD2), also known as manganese-dependent superoxide dismutase (MnSOD), is an enzyme which in humans is encoded by the SOD2 gene on chromosome 6. [ 5 ] [ 6 ] A related pseudogene has been identified on chromosome 1.
Irwin Fridovich and Joe McCord at Duke University discovered the enzymatic activity of superoxide dismutase in 1968. [5] SODs were previously known as a group of metalloproteins with unknown function; for example, CuZnSOD was known as erythrocuprein (or hemocuprein, or cytocuprein) or as the veterinary anti-inflammatory drug "Orgotein".

Mitochondrial ROS can promote cellular senescence and aging phenotypes in the skin of mice. [11] Ordinarily mitochondrial SOD2 protects against mitochondrial ROS. Epidermal cells in mutant mice with a genetic SOD2 deficiency undergo cellular senescence, nuclear DNA damage, and irreversible arrest of proliferation in a portion of their keratinocytes.
SOD1 binds copper and zinc ions and is one of three superoxide dismutases responsible for destroying free superoxide radicals in the body. The encoded isozyme is a soluble cytoplasmic and mitochondrial intermembrane space protein, acting as a homodimer to convert naturally occurring, but harmful, superoxide radicals to molecular oxygen and hydrogen peroxide.
It has been estimated that endogenous ROS produced via normal cell metabolism modify approximately 20,000 bases of DNA per day in a single cell. 8-oxoguanine is the most abundant among various oxidized nitrogeneous bases observed. During DNA replication, DNA polymerase mispairs 8-oxoguanine with adenine, leading to a G→T transversion mutation.
HSAB is an acronym for "hard and soft (Lewis) acids and bases".HSAB is widely used in chemistry for explaining the stability of compounds, reaction mechanisms and pathways. It assigns the terms 'hard' or 'soft', and 'acid' or 'base' to chemical species.
Like its predecessor, Bases Loaded II offers both a single-game mode and a single- player "pennant race" mode. In the "pennant race", a player must first achieve at least a 75-55 record during the regular season, then win a best-of-7 "World Series" against L.A. or N.Y. depending whether you have chosen a team from the Eastern or Western league respectively.
