Ouabain reduced T&lt;sub&gt;Na+&lt;\/sub&gt; and QO&lt;sub&gt;2&lt;\/sub&gt; in NK but not RK, and increased glucose consumption in RK (by 67%, p &lt; 0.02, n = 12) and NK (by 54%, p &lt; 0.05, n = 12). Raising perfusate pH by 0.3 U to 7.65 increased glucose production in RK but not NK and reduced T&lt;sub&gt;Na+&lt;\/sub&gt; in NK but not RK Dietary protein restriction reduced QO&lt;sub&gt;2&lt;\/sub&gt; (2.18 \u00b1 0.29 vs. 4.13 \u00b1 0.20 \u03bcmol-1 min-1 g-1 p &lt; 0.001), T&lt;sub&gt;Na+&lt;\/sub&gt; (8.74 \u00b1 4.39 vs. 38.83 \u00b1 8.32, p &lt; 0.01) and ammoniagenesis (0-30 min, 0.16 \u00b1 0.05 vs. 0.32 \u00b1 0.10, p &lt; 0.05) in RK, but not NK. In summary: (1) responses to ouabain and alkalosis, but not other metabolic inhibitors, were quite distinct in remnant versus normal kidneys, and (2) protein restriction limited sodium-transport-dependent and -independent hypermetabolism in RK.<\/jats:p>","DOI":"10.1159\/000187364","type":"journal-article","created":{"date-parts":[[2008,12,12]],"date-time":"2008-12-12T10:27:44Z","timestamp":1229077664000},"page":"417-423","source":"Crossref","is-referenced-by-count":6,"title":["Altered Metabolism in the ex vivo Remnant Kidney"],"prefix":"10.1159","author":[{"given":"David C.H.","family":"Harris","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ching","family":"Tay","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2008,12,12]]},"container-title":["Nephron"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/187364","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000187364","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T18:14:07Z","timestamp":1777659247000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000187364"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2008,12,12]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000187364","archive":["Portico"],"relation":{},"ISSN":["1660-8151","2235-3186"],"issn-type":[{"value":"1660-8151","type":"print"},{"value":"2235-3186","type":"electronic"}],"subject":[],"published":{"date-parts":[[2008,12,12]]}}}
