Data are presented on three edible species of tuber (<igna frutescens, Eminia entennulifa, and Ipomoea transvaalensis) consumed by Hadza foragers in northern Tanzania. These species are collected almost year-round by Hadza women but previous analyses of their macronutrient composition are variable and provide results based on the analysis of whole tuber. We examined only edible portions of tube...

The effects of reconstitution of sorghums on dry matter, energy, protein and amino acid digestibilities, and the nature of protein binding by sorghum tannins during digestion were investigated. Grains from a high and a low tannin sorghum were reconstituted by adding 30% (wt/wt) distilled water to the grain and stored at 25 degrees C for 20 days with an acetic-propionic acid mixture added to det...

In incubated colonocytes isolated from rat colons, the rates of utilization O2, glucose or glutamine were linear with respect to time for over 30 min, and the concentrations of adenine nucleotides plus the ATP/ADP or ATP/AMP concentration ratios remained approximately constant for 30 min. Glutamine, n-butyrate or ketone bodies were the only substrates that caused increases in O2 consumption by ...

Electron probe analysis of dry cryosections was used to determine the composition of the cytoplasm and organelles of rabbit portal-anterior mesenteric vein (PAMV) smooth muscle. All analytical values given are in mmol/kg wt --+ SEM. Cytoplasmic concentrations in normal, resting muscles were: K, 611 --1.7; Na, 167 _+ 2.7; C1, 278 -+ 1.0; Mg, 36 --1.1; Ca, 1.9 -+ 0.5; and P, 247 --1.1. Hence, the...

1. The rate of urine production in the terrestrial crabs Gecarcinus lateralis (Freminville) and Cardisoma guanhumi Latreille maintained on s.w.-moist sand was measured by inulin clearance. 2. The inulin U/B ratios in both species rose to about unity after 48 h, and remained at this level. It was concluded that neither species withdrew water from the primary urine. 3. The relatively high rate of...

Waon therapy (WT), which in Japanese means soothing warmth, is a repeated sauna therapy that improves cardiac and vascular endothelial function in patients with chronic heart failure (CHF). We investigated whether WT could improve the quality of life (QOL) of CHF patients in addition to improving cardiac function and exercise capacity.A total of 49 CHF patients (69 ± 14 years old) were treated ...

As substrate for evaluation of metabolic diseases, we developed novel rat models that contrast for endurance exercise capacity. Through two-way artificial selection, we created rodent phenotypes of intrinsically low-capacity runners (LCR) and high-capacity runners (HCR) that also differed markedly for cardiovascular and metabolic disease risk factors. Here, we determined skeletal muscle protein...

OBJECTIVE to investigate the changes of pyridine nucleotides and thiol redox state in cardiac tissue following ischemia and reperfusion. NADH/NAD and NADPH/NADP redox couples were specifically studied and the influence of NADPH availability on cellular thiol redox was also investigated. METHODS isolated rabbit hearts were Langendorff perfused and subjected to a protocol of ischemia and reperf...

Electron probe analysis of dry cryosections was used to determine the composition of the cytoplasm and organelles of rabbit portal-anterior mesenteric vein (PAMV) smooth muscle. All analytical values given are in mmol/kg wt +/- SEM. Cytoplasmic concentrations in normal, resting muscles were: K, 611 +/- 1.7; Na, 167 +/- 2.7; Cl, 278 +/- 1.0; Mg, 36 +/- 1.1; Ca, 1.9 +/- 0.5; and P, 247 +/- 1.1. H...
