Dietary cysteine reduces the methionine requirement in men
amino acid requirement stable isotopes methionine
2016/6/14
Despite early evidence suggesting that dietary cysteine
has a sparing effect on methionine requirements, some recent
reports question the existence of a measurable sparing capacity.
Total sulfur amino acid requirement in young men as determined by indicator amino acid oxidation with L-[1-13C]phenylalanine
amino acid requirement stable isotopes phenylalanine
2016/6/14
Determining the sulfur amino acid (SAA) requirements
of humans has remained elusive because of the complex
nature of SAA metabolism. Current recommendations are based
on nitrogen balance studies.
Effect of highly active antiretroviral therapy on fat, lean, and bone mass in HIV-seropositive men and women
lipodystrophy fat redistribution lean body mass
2016/6/14
Alterations in body composition have been
reported in HIV-positive adults receiving highly active antiretroviral
therapy (HAART), but the magnitude and potential determinants
of these changes are u...
Substrate oxidation and control of food intake in men after a fat-substitute meal compared with meals supplemented with an isoenergetic load of carbohydrate, long-chain triacylglycerols, or medium-chain triacylglycerols
Humans hunger signal satiety
2016/6/14
It has been suggested that hunger may be delayed
and food intake reduced under metabolic conditions that spare
carbohydrate oxidation.
Physical activity and energy intake selectively predict the waist-to-hip ratio in men but not in women
Body mass index sex energy intake
2016/6/14
The waist-to-hip ratio (WHR) has emerged as an
important risk factor for several chronic diseases, but little quantitative
information exists about its relation with energy intake
and expenditure i...
Effects of weekly administration of pegylated recombinant human OB protein on appetite profile and energy metabolism in obese men
Obesity leptin OB protein
2016/6/14
Results of leptin administration in mice, rats, and
humans provide a rationale for therapeutic augmentation of circulating
leptin (OB protein) concentrations in obese humans;
this may reduce food i...
Effects of different nutrient intakes on daytime triacylglycerolemia in healthy, normolipemic, free-living men
Diet carbohydrates triacylglycerol
2016/6/14
Postprandial studies with standardized mixed meals
have shown that ingestion of high-carbohydrate diets is associated
with elevated plasma triacylglycerol (TG) concentrations.
Effect of acute zinc depletion on zinc homeostasis and plasma zinc kinetics in men
rate constants plasma zinc zinc homeostasis
2016/6/14
Zinc homeostasis and normal plasma zinc concentrations
are maintained over a wide range of intakes.
Relation between body composition, fat distribution, and lung function in elderly men
Fat mass fat-free mass fat distribution
2016/6/13
Body composition changes with age, with increases
in fat mass and visceral fat and declines in skeletal muscle mass;
lung function also declines with age. Age-related changes in
body composition an...
Alcohol drinking determines the effect of the APOE locus on LDL-cholesterol concentrations in men: the Framingham Offspring Study
Apolipoprotein E genetics lipoproteins
2016/6/13
The effect of alcohol drinking on LDL-cholesterol
concentrations is unclear. The reported variability may be due to
interactions between genetic factors and alcohol intake.
In animals, the whole-body content and accumulation
of linoleate can be measured and compared with its intake
to determine linoleate -oxidation. This method can also provide
quantitative informatio...
Short-term effects of weight loss with or without low-intensity exercise training on fat metabolism in obese men
fat oxidation energy restriction low-energy diet
2016/6/12
Energy restriction is known to induce a decline in
fat oxidation during the postdiet period. Reduced fat oxidation
may contribute to weight regain.
Tyrosine requirement of healthy men receiving a fixed phenylalanine intake determined by using indicator amino acid oxidation
stable isotopes adult amino acid requirements Amino acid metabolism
2016/6/12
The currently accepted total aromatic amino acid
requirement for adults is based on nitrogen balance measurements
in individuals who received their intake of aromatic amino
acids solely as phenylal...
Postprandial de novo lipogenesis and metabolic changes induced by a high-carbohydrate, low-fat meal in lean and overweight men
Obesity hyperinsulinemia carbohydrates
2016/6/12
Adjustments of carbohydrate intake and oxidation
occur in both normal-weight and overweight individuals. Nevertheless,
the contribution of carbohydrates to the accumulation of
fat through either re...
Genetic, dietary, and other lifestyle determinants of plasma homocysteine concentrations in middle-aged and older Chinese men and women in Singapore
Homocysteine folate vitamin B-12
2016/6/12
Epidemiologic studies have identified the plasma
homocysteine concentration as a risk factor for atherothrombotic
vascular disease. There is little information on the distributions and
determinants...
