All people with dark skin are at risk for both skin conditions We previously reported that accentuated expression of the endothelin-1 (ET-1)/endothelin B receptor (ETBR) cascade is involved in the mechanism of hyperpigmentation in lentigo senilis (LS) lesions. Renal ischemia/reperfusion (I/R) injury, the major cause of acute kidney injury (AKI), is associated with severe morbidity and mortality in both developing and developed countries.
