TLDR
Kinetic studies reveal the enzymatic decomposition of H2O2 to follow first-order kinetics at lower substrate concentrations, and then to deviate from the original linearity, demonstrating mixed- order kinetics.About:

TL;DR: This work compared the sensitivities of presumptively homologous epithelial somatic cells derived from bird and mouse kidneys to various forms of oxidative stress and found enhanced resistance of avian cells from three species to 95% oxygen, hydrogen peroxide, paraquat, and gamma-radiation.

Changes in concentration, localization and activity of catalase within the human placenta during early gestation
TL;DR: Results are in agreement with the proposal that the placenta exists in a physiologically low oxygen environment during the early part of gestation, and oxidative activity of the sort resulting in the generation of hydrogen peroxide would presumably be suppressed.

Differences in the proteome profile in placenta from normal term and preeclamptic preterm pregnancies.
TL;DR: Endothelial monocyte‐activating polypeptide was shown to be down‐regulated in preeclampsia by 2‐DE and MS, and three proteins identified by MS to be Hsp27, catalase, and glucose‐regulated protein were confirmed by Western blot analysis to be significantly up‐regulated to be involved in regulatory pathways activated by stress.

A comparative study of 5'nucleotidase and alkaline phosphatase in human placenta during development
TL;DR: Alkaline phosphatase from a late stage of gestation appeared to be almost heat-stable and an appreciable part of 5’-nucleotidase was also resistant to heat inactivation and this fraction varied with gestational age of the tissue.
