We found low to high positive (r between 0.22–0.99) and significant correlation between PH and SD (0.99), SD and EH (0.82), EH and PH (0.95), and PH and EPO (0.95) under heat stress whereas EH and PH (0.72), EH and EPO (0.88), and AD and SD (0.87) showed strong positive association under normal conditions. This evidence concerns the gene EPO and Alzheimer disease.
