Effects of Dietary Interventions on the Aging Brain

2014-08-27 03:18:39 | BioPortfolio

Summary

The researchers will investigate whether caloric restriction or dietary supplementation could provide positive effects on general brain functions in healthy elderly people.

Description

The age-related degradation of cognitive functions even to the point of neurodegenerative disorders such as Alzheimer`s disease are a growing public-health concern with devastating effects.

Referring to animal data, empirical studies, and pilot human trials, a healthy diet rich in unsaturated fatty acids and low in calories should improve cognitive functions such as learning and memory. To test this hypothesis, the researchers study general brain functions in healthy elderly subjects (50-80 years old) during a short term diet.

Medical and Biotech [MESH] Definitions

Reduction in caloric intake without reduction in adequate nutrition. In experimental animals, caloric restriction has been shown to extend lifespan and enhance other physiological variables.

A subclass of cartilaginous fish comprising the SHARKS; rays; skates (SKATES (FISH);), and sawfish. Elasmobranchs are typically predaceous, relying more on smell (the olfactory capsules are relatively large) than sight (the eyes are relatively small) for obtaining their food.

An envelope of loose gel surrounding a bacterial cell which is associated with the virulence of pathogenic bacteria. Some capsules have a well-defined border, whereas others form a slime layer that trails off into the medium. Most capsules consist of relatively simple polysaccharides but there are some bacteria whose capsules are made of polypeptides.

FATTY ACIDS which have the first unsaturated bond in the sixth position from the omega carbon. A typical American diet tends to contain substantially more omega-6 than OMEGA-3 FATTY ACIDS.

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.
