Efficacy of a green tea extract rich in catechin polyphenols and caffeine in increasing 24-h energy expenditure and fat oxidation in humans.
BACKGROUND Current interest in the role of functional foods in weight control has focused on plant ingredients capable of interfering with the sympathoadrenal system. OBJECTIVE We investigatedExpand

Green tea and thermogenesis: interactions between catechin-polyphenols, caffeine and sympathetic activity
The thermogenic effect of tea is generally attributed to its caffeine content. We report here that a green tea extract stimulates brown adipose tissue thermogenesis to an extent which is much greaterExpand

A STUDY OF THE T SYSTEM IN RAT HEART
The technique of extracellular space tracing with horseradish peroxidase is adapted for labeling the transverse tubular system (T system) in rat heart. In rat ventricular muscle the T system showsExpand

Membrane Potential of Brown Adipose Tissue A suggested mechanism for the regulation of thermogenesis
Membrane potentials were recorded in isolated segments of interscapular brown adipose tissue from rats. After equilibration at 29°C in Krebs-Ringer bicarbonate buffer a mean value of -51 ± 4 mv (SD)Expand

CORRELATED MORPHOLOGICAL AND PHYSIOLOGICAL STUDIES ON ISOLATED SINGLE MUSCLE FIBERS
Single fibers isolated from walking leg muscles of crayfish have 8- to 10-µ sarcomeres which are divided into A, I, and Z bands. The H zone is poorly defined and no M band is distinguishable. ChangesExpand

Twenty-four-hour energy expenditure and urinary catecholamines of humans consuming low-to-moderate amounts of medium-chain triglycerides: a dose-response study in a human respiratory chamber.
OBJECTIVE To determine whether medium-chain triglycerides, in low-to-moderate amounts consumed with meals (at breakfast, lunch and dinner), can increase daily energy expenditure (EE) and 24-h urinaryExpand

Poststarvation hyperphagia and body fat overshooting in humans: a role for feedback signals from lean and fat tissues.
An increase in the sensation of hunger and overeating after a period of chronic energy deprivation can be part of an autoregulatory phenomenon attempting to restore body weight. To gain insights intoExpand

Autoregulation of body composition during weight recovery in human: the Minnesota Experiment revisited.
OBJECTIVES To gain insights into the control systems underlying human variability in the regulation of body composition during weight recovery, as well as the disproportionate recovery of fatExpand

Thermogenesis associated with spontaneous activity: an important component of thermoregulatory needs in rats.
1. Quantification of the energy cost of spontaneous activity in freely moving lean and obese Zucker rats was performed at 28 degrees C and during acute cold exposure (from 28 to 5 degrees C). 2. AnExpand

Adaptive changes in energy expenditure during refeeding following low-calorie intake: evidence for a specific metabolic component favoring fat storage.
Studies in this report investigate the existence and quantitative contribution of a metabolic component to an apparently elevated efficiency of energy utilization during refeeding followingExpand
