“…These OS markers encompass molecules that undergo modifications as a consequence of ROS interactions, as well as components of the antioxidant system that undergo changes and modifications in response to stress conditions [187]. The selection of an OS marker relies on specific criteria, including its specificity, sensitivity to elevated ROS levels, temporal stability enabling sample collection and analysis, and result in reproducibility [188].…”

“…DNA, lipids (including phospholipids), proteins, and carbohydrates exemplify molecules susceptible to in vivo modifications induced by excessive ROS levels [188]. Hence, indirect assessment of ROS levels by examining oxidative damage to lipids, proteins, and nucleic acids within cellular systems presents a promising alternative for evaluating OS in clinical samples.…”

Recent years have seen an increased interest in the role of oxidative stress (OS) in pregnancy. Pregnancy inherently heightens susceptibility to OS, a condition fueled by a systemic inflammatory response that culminates in an elevated presence of reactive oxygen species (ROS) and reactive nitrogen species (RNS) in the circulatory system. The amplified OS in pregnancy can trigger a series of detrimental outcomes such as underdevelopment, abnormal placental function, and a host of pregnancy complications, including pre-eclampsia, embryonic resorption, recurrent pregnancy loss, fetal developmental anomalies, intrauterine growth restriction, and, in extreme instances, fetal death. The body’s response to mitigate the uncontrolled increase in RNS/ROS levels requires trace elements that take part in non-enzymatic and enzymatic defense processes, namely, copper (Cu), zinc (Zn), manganese (Mn), and selenium (Se). Determination of ROS concentrations poses a challenge due to their short half-lives, prompting the use of marker proteins, including malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GPx), glutathione reductase (GR), catalase (CAT), and glutathione (GSH). These markers, indicative of oxidative stress intensity, can offer indirect assessments of pregnancy complications. Given the limitations of conducting experimental studies on pregnant women, animal models serve as valuable substitutes for in-depth research. This review of such models delves into the mechanism of OS in pregnancy and underscores the pivotal role of OS markers in their evaluation.

“…Subsurface sediments were sampled from a well characterised eld site in west Cumbria representative of the Sellaeld subsurface. 95,99 The sediments were sampled at approximately 10 cm depth into sealed, sterile HDPE bags, which were stored at 10 °C prior to use. For detailed analysis, see ESI Section SI1.…”

The body’s response to mitigate the uncontrolled increase in RNS/ROS levels involves trace elements that take part in non-enzymatic and enzymatic defense mechanisms, namely, copper (Cu), zinc (Zn), manganese (Mn), iron (Fe), and selenium (Se). Determination of ROS concentrations poses a challenge due to their short lifespan, prompting the use of marker proteins, including malondialdehyde (MDA), superoxide dis-mutase (SOD), glutathione peroxidase (GPx), glutathione reductase (GR), lipid peroxidation (LPO), catalase (CAT), and glutathione (GSH). These markers, indicative of redox stress intensity, can offer indirect assessments of pregnancy complications. Given the limitations in conducting experimental studies on pregnant women, animal models serve as valuable substitutes for in-depth research. This review delves into the mechanism of OS in pregnancy and underscores the pivotal role of markers in its evaluation.
