Constitutive transgenic α-Klotho overexpression enhances resilience to and recovery from murine acute lung injury.

Normal lungs do not express α-Klotho (Klotho) protein but derive cytoprotection from circulating soluble Klotho. It is unclear whether chronic supranormal Klotho levels confer additional benefit. To address this, we tested the age-related effects of modest Klotho overexpression on acute lung injury (ALI) and recovery.

Net Acid Excretion and Urinary Organic Anions in Idiopathic Uric Acid Nephrolithiasis.

Background And Objectives: Idiopathic uric acid nephrolithiasis, which is closely associated with obesity and the metabolic syndrome, is increasing in prevalence. Unduly acidic urine pH, the quintessential pathophysiologic feature of this disease, is in part explained by inadequate excretion of the principal urinary buffer ammonium. The role of net acid excretion in the pathogenesis of uric acid nephrolithiasis is incompletely understood.
