1. Lesions in the lateral hypothalamus of rats always produced an immediate increase in total energy expenditure. The increase was maintained for 24 hr or longer only in rats that became and remained aphagic. Rats that showed no recovery from the aphagia and were maintained by tube feeding showed a second, larger increase in metabolic rate after about 7 ...

BACKGROUND AND PURPOSEMR spectroscopic imaging (MRSI) and dynamic susceptibility-contrast MR imaging (DSC-MR imaging) are functional in vivo techniques for assessing tumor metabolism and vasculature characteristics. Because tumor hypoxia is influenced by tortuous, degraded, swollen, and angiogenic tumor vasculature, regions of abnormal perfusion parameters ...

OBJECTIVEWe examined maximal graded exercise test (GXT) results in 5,783 overweight/obese men and women, aged 45�76 years, with type 2 diabetes, who were entering the Look AHEAD (Action for Health in Diabetes) study, to determine the prevalence and correlates of exercise-induced cardiac abnormalities.RESEARCH DESIGN AND METHODSParticipants underwent symptom-limited maximal ...

Using isolated rat hearts, studies will be performed focusing upon key amino acids which coordinate glycolysis with ATP production, thus defining those metabolic abnormalities of cellular energy production systems in ischemic myocardium which lead to irre...

Abnormalities of the skeletal and urogenital system are discussed which result from an interference with the metabolism of calcium in cadmium workers.

Previous studies have reported differences in muscle function and metabolism between patients with cystic fibrosis (CF) and healthy controls (HC), but it is currently unknown whether these abnormalities are specific to CF or also seen in other airway diseases. In this study, we used magnetic resonance spectroscopy (MRS) during exercise to assess muscle ...
