A Mathematical Model of Tryptophan Metabolism via the Kynurenine Pathway Provides Insights into the Effects of Vitamin B-6 Deficiency, Tryptophan Loading, and Induction of Tryptophan 2,3-Dioxygenase on Tryptophan Metabolites

Publikováno v: The Journal of Nutrition. 143:1509-1519
Vitamin B-6 deficiency is associated with impaired tryptophan metabolism because of the coenzyme role of pyridoxal 5′-phosphate (PLP) for kynureninase and kynurenine aminotransferase. To investigate the underlying mechanism, we developed a mathemat

Autor: Harry S. Sitren, Joshua F. Yarrow, Bruce R. Stevens, Lesley J. White, Paul A. Borsa, Stephen E. Borst
Publikováno v: Journal of Strength and Conditioning Research. 22:1205-1214
The purpose of this study was to evaluate the early-phase muscular performance adaptations to 5 weeks of traditional (TRAD) and eccentric-enhanced (ECC+) progressive resistance training and to compare the acute postexercise total testosterone (TT), b

Effects of variation in protein and carbohydrate intake on body mass and composition during energy restriction: a meta-regression
Autor: Bobbi Langkamp-Henken, Michael J. Daniels, Harry S. Sitren, James W. Krieger
Publikováno v: The American Journal of Clinical Nutrition. 83:260-274
Background It is unclear whether low-carbohydrate, high-protein, weight-loss diets benefit body mass and composition beyond energy restriction alone. Objective The objective was to use meta-regression to determine the effects of variations in protein

The zinc transporter Zip14 influences c-Met phosphorylation and hepatocyte proliferation during liver regeneration in mice
Autor: Tolunay Beker Aydemir, Robert Cousins, Harry S. Sitren
Publikováno v: Gastroenterology. 142(7)
Background & Aims Zinc homeostasis in cells is maintained through tight regulation of zinc influx, efflux, and distribution to intracellular organelles by zinc transporters. The Zrt-Irt-like protein (ZIP) transporters facilitate zinc influx to the cy

The Effects of Glutamine-enriched Total Parenteral Nutrition on Tumor Growth and Host Tissues
Autor: Harry S. Sitren, Kirby I. Bland, Wiley W. Souba, Thomas R. Austgen, Edward M. Copeland, Paul S. Dudrick
Publikováno v: Annals of Surgery. 215:107-113
The effects of glutamine-enriched total parenteral nutrition (TPN+GLN) were studied in tumor-bearing rats because glutamine can benefit host tissues but also may stimulate tumor growth. Rats were implanted with the methylcholanthrene-induced fibrosar

Differential role of prostaglandin E1 on tumor metastasis
Autor: Harry S. Sitren, Lee M. Ellis, Edward M. Copeland, Kirby I. Bland
Publikováno v: Journal of Surgical Research. 48:333-336
Previous studies from our laboratory have shown that intravenous (iv) infusion of pharmacologic doses of prostaglandin E1 (PGE1) inhibits "spontaneous" metastases in mice bearing Lewis Lung carcinoma (LLC). This study was done to determine the effect

Neuroendocrine responses to an acute bout of eccentric-enhanced resistance exercise
Autor: Paul A. Borsa, Lesley J. White, Bruce R. Stevens, Stephen E. Borst, Joshua F. Yarrow, Harry S. Sitren
Publikováno v: Medicine and science in sports and exercise. 39(6)
Purpose: Hypoxia is known to change neuronal activity in vitro and to impair performance in vivo. The present study was designed to study neuromuscular fatigue in acute hypoxia, and we hypothesized that hypoxia results in additional fatigue during su

Pharmacologic levels of dietary arginine in CB6F1 mice increase serum ammonia in the healthy state and serum nitrite in endotoxemia
Autor: Kelli A. Herrlinger-Garcia, Carmelo Nieves, Harry S. Sitren, Bobbi Langkamp-Henken
Publikováno v: JPEN. Journal of parenteral and enteral nutrition. 31(2)
Therapeutic or pharmacologic doses of arginine are used to enhance blood flow and immune function despite the lack of dose-response studies and the potential for adverse effects. This study determined the optimal level of oral arginine supplementatio
