When these algae experience stress such as intense sunlight, nutrient scarcity, or high salinity they begin producing astaxanthin as a shield to protect their cells from oxidative damage.16 Many marine animals feed on these algae, such as:17 Salmon Shrimp Krill Trout Flamingos These animals absorb and store the pigment in their tissues, which gives them their distinctive pink or reddish coloration.18 What makes astaxanthin compelling is that the same compound algae use to shield their cells from light, heat, and environmental stress may also help human cells withstand similar challenges

7 Imaging biomarkers 7.1 Imaging markers based on ultrasound Transcranial ultrasonography, with a diagnostic sensitivity of 84% and specificity of 85%, can identify anomalies of nigral iron deposition in PD patients, which present as nigral hyperechoicity (Tao et al., 2019)
