Impaired Regulation of Energy Balance in Elderly People (Balance Study)
Over the past century life expectancy has risen rapidly. As a result, the proportion of elderly people continues to grow. Elderly people probably have an impaired regulation of energy balance (energy intake versus energy expenditure) whereby the underlying physiological mechanisms are not fully understood.
The first objective of this study is to provide further evidence for an age-related failure to regulate energy balance in elderly. If the hypothesis of impaired regulation of energy balance in elderly is confirmed then the second objective becomes to elucidate the underlying physiological mechanisms of the age-related failure to regulate energy intake in elderly.

Medical and Biotech [MESH] Definitions
Optical Restriction Mapping
A technique to generate restriction maps from single large DNA molecules by spreading the DNA onto a glass surface, digesting with DNA RESTRICTION ENZYMES, staining with FLUORESCENT DYES, and visualizing the DNA cleavage sites by FLUORESCENCE MICROSCOPY.
Dna Restriction-modification Enzymes
Systems consisting of two enzymes, a modification methylase and a restriction endonuclease. They are closely related in their specificity and protect the DNA of a given bacterial species. The methylase adds methyl groups to adenine or cytosine residues in the same target sequence that constitutes the restriction enzyme binding site. The methylation renders the target site resistant to restriction, thereby protecting DNA against cleavage.
The lack or loss of APPETITE accompanied by an aversion to food and the inability to eat. It is the defining characteristic of the disorder ANOREXIA NERVOSA.
Use of restriction endonucleases to analyze and generate a physical map of genomes, genes, or other segments of DNA.
Bioelectric Energy Sources
Electric power supply devices which convert biological energy, such as chemical energy of metabolism or mechanical energy of periodic movements, into electrical energy.
The purpose of this study is to investigate the potential biological predispositions that contribute to the difficulty patients with anorexia nervosa have in maintaining normal weight.
UCAN is a research program funded by the National Institute of Mental Health and is part of the UNC Eating Disorders Program. UCAN aims to help couples work together in the treatment of an...
These studies will provide us with enormous insight regarding how obese patients adapt energetically during negative energy balance. We will gain fundamental information regarding the met...
The purpose of this study is to identify how adult men respond to a weight loss diet that includes pork and eggs and increasing the number of meals consumed throughout the day. This is a...
This open trial seeks to investigate the feasibility and effectiveness of delivering a newly manualized family-based treatment for adolescents with anorexia nervosa at a site beyond the tr...
Ageing is a complex multifactorial process involving a progressive physiological decline that, ultimately, leads to the death of an organism. It involves multiple changes in many components that play...
Osteoporosis is common in anorexia nervosa. It places these patients at increased lifetime risk for fractures. Bone loss may never recover completely even once weight is restored. The strongest predic...
OBJECTIVE In this review, based on recent advances in cognitive neuroscience, the author presents a formulation in which the marked persistence of anorexia nervosa can be usefully understood as a well...
Anorexia nervosa is a complex eating disorder of unknown etiology which affects adolescent girls and young women and leads to chronic malnutrition. Clinical manifestations of prolonged semistarvation...
Ageing is often deemed bad for people and something that ought to be eliminated. An important aspect of this normative aspect of ageing is whether ageing, i.e., senescence, is a disease. In this essay...
