No evidence of racial disparities in blood pressure salt sensitivity when potassium intake exceeds levels recommended in the US dietary guidelines.
Kurtz TW, DiCarlo SE, Pravenec M, Morris RC Jr. Kurtz TW, et al. Among authors: morris rc jr. Am J Physiol Heart Circ Physiol. 2021 May 1;320(5):H1903-H1918. doi: 10.1152/ajpheart.00980.2020. Epub 2021 Apr 2. Am J Physiol Heart Circ Physiol. 2021. PMID: 33797275 Free PMC article. Review.
In this narrative review, we analyze those studies and note that when potassium intake substantially exceeds the recently recommended US dietary goal of 87 mmol/day, black adults do not appear more sensitive than white adults to BP effects of short-term or long-term …

Testing Computer Models Predicting Human Responses to a High-Salt Diet.
Kurtz TW, DiCarlo SE, Pravenec M, Ježek F, Šilar J, Kofránek J, Morris RC Jr. Kurtz TW, et al. Among authors: morris rc jr. Hypertension. 2018 Dec;72(6):1407-1416. doi: 10.1161/HYPERTENSIONAHA.118.11552. Hypertension. 2018. PMID: 30571226 Free PMC article.
Furthermore, although both contemporary models are extensions of the 1972 Guyton model, testing revealed major inconsistencies between model predictions with respect to sodium balance and hemodynamic responses of normal subjects to short-term and long-term salt load …

Logical Issues With the Pressure Natriuresis Theory of Chronic Hypertension.
Kurtz TW, DiCarlo SE, Morris RC Jr. Kurtz TW, et al. Among authors: morris rc jr. Am J Hypertens. 2016 Dec 1;29(12):1325-1331. doi: 10.1093/ajh/hpw073. Am J Hypertens. 2016. PMID: 28637271 Free PMC article.
The term "abnormal pressure natriuresis" refers to a subnormal effect of a given level of blood pressure (BP) on sodium excretion. ...This theory would appear to follow from "the three laws of long-term arterial pressure regulation" stated by Guyton and Coleman more …

Metabolic and physiologic improvements from consuming a paleolithic, hunter-gatherer type diet.
Frassetto LA, Schloetter M, Mietus-Synder M, Morris RC Jr, Sebastian A. Frassetto LA, et al. Among authors: morris rc jr. Eur J Clin Nutr. 2009 Aug;63(8):947-55. doi: 10.1038/ejcn.2009.4. Epub 2009 Feb 11. Eur J Clin Nutr. 2009. PMID: 19209185 Clinical Trial.
In all these measured variables, either eight or all nine participants had identical directional responses when switched to paleolithic type diet, that is, near consistently improved status of circulatory, carbohydrate and lipid metabolism/physiology. CONCLUSIONS: Even short-t …

Long-term persistence of the urine calcium-lowering effect of potassium bicarbonate in postmenopausal women.
Frassetto L, Morris RC Jr, Sebastian A. Frassetto L, et al. Among authors: morris rc jr. J Clin Endocrinol Metab. 2005 Feb;90(2):831-4. doi: 10.1210/jc.2004-1350. Epub 2004 Nov 30. J Clin Endocrinol Metab. 2005. PMID: 15572425 Clinical Trial.
In the latter, who have substantial risk of calcium deficiency, it remains unknown whether the observed short-term urine calcium-lowering effect of KBC persists over years. We studied 170 postmenopausal women randomized to KBC 30, 60, or 90 mmol/d (KBC treatment), or place …

Evidence for a difference in vitamin D metabolism between spontaneously hypertensive and Wistar-Kyoto rats.
Kurtz TW, Portale AA, Morris RC Jr. Kurtz TW, et al. Among authors: morris rc jr. Hypertension. 1986 Nov;8(11):1015-20. doi: 10.1161/01.hyp.8.11.1015. Hypertension. 1986. PMID: 3770864
The activity of 25-hydroxyvitamin D-1 alpha-hydroxylase, however, appears to be at least partially responsive to short-term restriction of dietary phosphorus. In SHR, the activity of 25-hydroxyvitamin D-1 alpha-hydroxylase may be lower than that in WKY, perhaps due in part …

Effect of dietary phosphorus on circulating concentrations of 1,25-dihydroxyvitamin D and immunoreactive parathyroid hormone in children with moderate renal insufficiency.
Portale AA, Booth BE, Halloran BP, Morris RC Jr. Portale AA, et al. Among authors: morris rc jr. J Clin Invest. 1984 Jun;73(6):1580-9. doi: 10.1172/JCI111365. J Clin Invest. 1984. PMID: 6547151 Free PMC article.
In a group of eight children with moderate renal insufficiency, mean glomerular filtration rate (GFR) 45 +/- 4 (SE) ml/min per 1.73 M2, ages 6-17 yr, we tested these hypotheses by determining the effect of short term (5 d) restriction and supplementation of dietary intake …
