Reviews a study which sought to obtain a quantitative metabolic map of the neurons mediating a specific memory. Research results support notions of cooperative processes in which nonrandom behavior of high ensembles of neural elements mediates the integration and processing of information and the retrieval of memory. (ML)

Reviews effects of hormones, systemic factors, and local regulators on bone formation. Identifies and explains the impact on bone growth of several hormones as well as the components of systemic and local systems. Concentrates on bone collagen and DNA synthesis. (Physicians may earn continuing education credit by completing an appended test). (ML)

Presented was the medical case history of a 4 year old female suffering from saccharopinuria, a newly found disorder of lysine metabolism in man. (GW)

TCDC electrophysiologic recordings, histamine wheal tests, eosinophile counts, blood cortisol determinations, and behavioral observations were conducted on 15 autistic children and on controls to study several interrelationships, particularly malabsorption and cerebral dysfunction. (Author)

Describes an experiment which gives students experience with uncertainties encountered in studying metabolic pathways; handling/use of radioisotopes; application of thin layer chromatography; and liquid scintillation counting and fluorography as methods of detecting radioactivity. The experiment can be accomplished in two to three laboratory…

Studies demonstrate increasing glucose metabolic rates in human primary (PVC) and association (AVC) visual cortex as complexity of visual scenes increase. AVC increased more rapidly with scene complexity than PVC and increased local metabolic activities above control subject with eyes closed; indicates wide range and metabolic reserve of visual…

This syllabus reviews information concerning calcium and phosphate regulation. Topics of interest include the following: calcium metabolism, phosphorus metabolism, bone, parathyroid hormone, calcitonin, and vitamin D. (CS)

Presents questions and answers about the effect of metabolism on substances in the human body. (MLH)

Presents a laboratory experiment on animal metabolism that uses a guided-inquiry approach. Discusses observed behaviors and improvements in students' understanding. (YDS)

In terms of physical impact, recent studies suggest that many benefits previously attributed to exercise as a factor in weight loss do not exist. Researchers do seem to agree that exercise does have a positive effect on body composition during weight loss. (IAH)

The Briggs-Haldane assumption is used as the basis for the development of a kinetic model for enzyme catalysis. An alternative definition of the steady state and examples of realistic mechanisms are provided. (KR)

Using graphs and diagrams, the authors describe a simple fermentation chamber and provide key experiments that can be used in the classroom to give students meaningful insight into metabolic processes. (ZWH)

To illustrate the possible relationships between metabolic disorders and autism, this commentary reviews findings from studies on the characteristics of individuals with Rett syndrome that indicate the genetic mechanism of transcriptional dysregulation can produce pathologic phenotypes which resemble metabolic disorders that stunt axonodendritic…
