Objective: The objective of this study was to examine the relation
between alcohol...
Energy metabolism after 2 y of energy restriction: the Biosphere 2 experiment
Metabolic rate physical activity energy restriction aging
2016/6/8
Background: An adaptive decrease in energy expenditure (EE) in
response to 6 mo of severely restricted energy intake was shown
in a classic semistarvation study—the Minnesota experiment.
Objective:...
Response of glutamine metabolism to glutamine-supplemented parenteral nutrition
Glutamine metabolism total parenteral nutrition glutamine supplementation glutamine dipeptides
2016/6/8
Background: Increasing evidence suggests that glutamine is
important for the function of many organ systems and supports
the use of glutamine-enriched total parenteral nutrition (TPN)
during severe...
Assessment of vitamin B-12, folate, and vitamin B-6 status and relation to sulfur amino acid metabolism in neonates
Homocysteine cysteine vitamin B-12 folate, vitamin B-6 neonates infants infant nutrition
2016/6/8
Background: Total serum homocysteine (tHcy) has been used as
an indicator of intracellular vitamin B-12, vitamin B-6, and folate
status in adults, but data for neonates and infants are lacking.
Vit...
Does dietary creatine supplementation play a role in skeletal muscle metabolism and performance?
Creatine uptake phosphocreatine ATP resynthesis exercise performance human skeletal muscle
2016/6/7
Fatigue sustained during short-term, highintensity
exercise in humans is associated with the inability of
skeletal muscle to maintain a high rate of anaerobic ATP production
from phosphocreatine hy...
The aging process as a modifier of metabolism
Aging elderly nutrient requirements metabolism, dietary requirements absorption
2016/6/7
Because elderly adults have distinct metabolic
characteristics that alter various nutrient requirements, simple
extrapolations of nutrient requirements for younger adults are
not warranted. Gastroi...
Sex-related differences in methionine metabolism and plasma homocysteine concentrations
Homocysteine sex amino acids kinetics, sulfur amino acids methionine,
2016/6/7
Background: Elevated fasting homocysteine concentrations are
considered a risk factor for vascular disease. Homocysteine, which
is produced by the transmethylation of methionine, can be either
reme...
Effects of changes in body weight on carbohydrate metabolism, catecholamine excretion, and thyroid function
Obesity diabetes glucose catecholamines, thyroid hormones weight change energy homeostasis body weight adult
2016/6/7
Background: Weight gain and loss increases and decreases
energy expenditure, respectively, out of proportion to changes in
metabolic mass.
Objective: We hypothesized that changes in energy expendit...
Physiology of pregnancy and nutrient metabolism
Pregnancy protein energy basal metabolism, food intake physical activity physiology
2016/6/7
Pregnancy consists of a series of small, continuous
physiologic adjustments that affect the metabolism of all
nutrients. The adjustments undoubtedly vary widely from
woman to woman depending on her...
