Effect of Aging Upon Small Intestinal Structure in the Fischer Rat

Holt, Peter, R.; Pascal, Robert, R.; Kotler, Donald, P.

1984 Journal of Gerontology

doi:10.1093/geronj/39.6.642 pmid:6491177

Abstract The dimensions and composition of the small intestine were studied in fed aged (27 month) and young adult (4 to 5 months) male fischer rats maintained under barrier-reared, controlled conditions. In the proximal intestine (duodenum and jejunum) of aged rats there was no reduction in...

Circadian Endocrine Time Structure in Humans Above 80 Years of Age

Lakatua, David, J.; Nicolau, Grazziela, Y.; Bogdan,, Constantin; Petrescu,, Elena; Sackett-Lundeen, Linda, L.; Irvine, Patrick, W.; Haus,, Erhard

1984 Journal of Gerontology

doi:10.1093/geronj/39.6.648 pmid:6092453

Abstract The circadian rhythms in blood hormone concentrations of 17 pituitary, adrenal, pancreatic, testicular, and thyroid hormones were determined in 9 women and 5 men 81 to 91 years of age. Six samples over a 24-hr span were studied for each hormone. Even with the small sample available, 9 of...

Aging and Sleep Apnea: Action of Benzodiazepine, Acetazolamide, Alcohol, and Sleep Deprivation in a Healthy Elderly Group

Guilleminault,, Christian; Silvestri,, Rosalia; Mondini,, Susanna; Coburn,, Steven

1984 Journal of Gerontology

doi:10.1093/geronj/39.6.655 pmid:6491178

Abstract Ten nonobese, healthy elderly adults (M = 73.3 years) were monitored polygraphically during sleep for sleep state changes, breathing, and the development of cardiac arrhythmias. All participated in 2 baseline nights and 1 night of flurazepam 30 mg ingestion; six underwent 1 night of...

The Effect of Age on Variability in Gait

Gabell,, A.; Nayak,, U.S.L.

1984 Journal of Gerontology

doi:10.1093/geronj/39.6.662 pmid:6491179

Abstract The intercycle variability in gait of two temporal parameters (stride time and double-support time) and the step-to-step variability of two spatial parameters (step length and stride width) were assessed in 64 healthy adults, 32 aged 21 to 47 and 32 aged 66 to 84. For all parameters the...

Deterioration of Beta-Receptor-Adenylate Cyclase Function in Elderly, Hospitalized Patients

Stessman,, Jochanan; Eliakim,, Rami; Cahan,, Clement; Ebstein, Richard, P.

1984 Journal of Gerontology

doi:10.1093/geronj/39.6.667 pmid:6092454

Abstract Salbutamol infusion was used to study the molecular basis for reduced catecholamine responsiveness in a group of elderly hospitalized individuals. Salbutamol-induced plasma cyclic 3′, 5′-adenosine monophosphate (cyclic AMP) rise in a group of 10 elderly (mean age 77 years) patients, 8 of...

Effects of Intravenous Glucose on Whole Body Leucine Dynamics, Studied With 1-13C-Leucine, in Healthy Young and Elderly Adults

Robert,, Jean-Jacques; Bier,, Dennis; Schoeller,, Dale; Wolfe,, Robert; Matthews, Dwight, E.; Munro, Hamish, N.; Young, Vernon, R.

1984 Journal of Gerontology

doi:10.1093/geronj/39.6.673 pmid:6386947

Abstract We examined whole body leucine metabolism in healthy young and elderly adults while in the postabsorptive state and during an intravenous glucose administration at two rates. Leucine flux, incorporation into whole body protein, and oxidation were estimated from a continuous intravenous...

Pathogenesis of Bacteriuria in Elderly Women: The Role of Escherichia Coli Adherence to Vaginal Epithelial Cells

Sobel, Jack, D.; Muller,, Gregory

1984 Journal of Gerontology

doi:10.1093/geronj/39.6.682 pmid:6386948

Abstract In vitro Escherichia coli adherence to exfoliated epithelial cells obtained from a group of elderly women was compared with adherence values in young healthy women in an attempt to define the role of adherence as an independent host risk factor for the acquisition of bacteriuria....

Systematic Biases in Functional Status Assessment of Elderly Adults: Effects of Different Data Sources

Rubenstein, Laurence, Z.; Schairer,, Catherine; Wieland, G., Darryl; Kane,, Rosalie

1984 Journal of Gerontology

doi:10.1093/geronj/39.6.686 pmid:6436360

Abstract Measuring functional status using specific instruments is an important part of geriatric assessment. These instruments, however, often rely on data sources different from those with which they were originally validated. To study possible biasing effects of different data sources on...

Autobiographical Memory Across the Life-span

Fitzgerald, Joseph, M.; Lawrence,, Renee

1984 Journal of Gerontology

doi:10.1093/geronj/39.6.692 pmid:6491180

Abstract The processes of autobiographical memory were studied in four groups with mean ages of 12.7, 19.1, 44.5, and 67.2 years. Participants provided memories of specific events in response to single-word prompts. Analyses of response time and age of memories indicated response time remains...
