For 1 wk, 3-mo-old male rats were fed a low-starch (5 cal%), high-fat (73 cal%, corn oil) diet followed by a high-glucose-polymer (70 cal%), low-fat (7 cal%, corn oil) or a middle-glucose-polymer (40 cal%), middle-fat (37 cal%, corn oil) diet. Other animals were fed similar diets but with starch or sucrose instead of the glucose polymers. Rats were sacrificed 2 or 7 days later. Food intake, bod...

This study investigated the effect of carbohydrate (CHO) ingestion on postexercise glycogen resynthesis, measured simultaneously in liver and muscle (n = 6) by (13)C magnetic resonance spectroscopy, and subsequent exercise capacity (n = 10). Subjects cycled at 70% maximal oxygen uptake for 83 +/- 8 min on six separate occasions. At the end of exercise, subjects ingested 1 g/kg body mass (BM) gl...

Effects of D 600, papaverine and KCN on sustained contracture induced by 20 mM KCl in a Na+-free sucrose- or Tris-substituted solution were investigated in the taenia coli of guinea pigs. D 600 (10(-5) M) and papaverine (10(-4) M), added after 40 min incubation in the 20 mM KCl sucrose solution, relaxed the muscle by 88.2 +/- 8.0% (mean +/- S.E., n = 4) and 78.8 +/- 6.3% (n = 4), respectively. ...

In severe hypercholesterolemia and sometimes even in normolipemia, lipoprotein-derived cholesterol accumulates in the skin, forming xanthomas, but the local factors triggering this accumulation are not known. We therefore studied the effect of immunoglobulin E (IgE)-mediated stimulation of cutaneous mast cells on the transport of low density lipoprotein (LDL) from plasma to skin during the pass...

tuberose (polianthus tuberosa) is a commercially important cut flower; but its longevity and quality characteristics are compromised by stress during storage and transportation. thus, it is important to determine the most appropriate preservative solution to best maintained cut flowers. tests were done to examine the effects on of nano-silver (ns) (0, 15, 30 and 45 mg l-1) and sucrose (0, 4 and...

A thiobarbituric acid (TBA) reaction for measuring lipid peroxidation products was evaluated for interference by several ingredients commonly used in solutions to prepare or analyze tissue homogenates or subcellular organelles. These included sucrose (up to 100 mM final concentration in the assay medium), Tris-maleate (up to 40 mM), imidazole (up to 20 mM), inorganic phosphate (up to 10 mM), an...

The objective of the study is to assess the influence of temperature, time and enzymatic pretreatment on the osmotic concentration of gooseberry fruits (cultivar Biały Triumf). The fruits were osmotically concentrated in a sucrose solution at 65 °Brix and 40 to 70 °C for 5 to 240 min. Two experimental procedures were employed. In the first procedure, prior to concentration the fruits were immer...

the use of isomalt and maltitol instead of sucrose in foods has an important role in human health as controlling blood glucose levels and weight management. in this study, isomalt and maltitol instead of sucrose were used at three concentration level (75, 85, and 100%). effects of the polyols were investigated on physicochemical properties (size of bubble cake batter, moisture content, water ac...
