Blood lipids in young and old individuals.
HAVE BEEN INTERESTED in the blood lipids and lipoproteins in relation to the process of aging and to the incidence of cardiovascular disease. Studies on the serum lipoproteins as measured by the cholesterol distribution in zone electrophoresis and on other changes of the blood lipids with age have been made (1, 2). Recently the effects of the amount and type of fat in the dietary intake on the ...
متن کاملRegeneration and transplantation of muscles in old rats and between young and old rats.
In order to compare the regenerative ability of skeletal muscle between young (5month) and old (26 month) rats, sliced or intact extensor digitorum longus muscles were freely autografted into young and old rats and also reciprocally grafted from young to old inbred animals and vice versa . Sixty days after grafting, the transplants were analyzed for contractile and histochemical properties . Th...
متن کاملAgglutination by polylysine of young and old red blood cells.
The rate of agglutination by polylysine of young and old human erythrocytes was automatically recorded and correlated with measurements of the electrophoretic mobility of these cells. Old red cells have a reduced electrophoretic mobility as compared with young cells, as well as a higher rate of agglutination than young cells. Mild treatment of red cells with receptor destroying enzyme (RDE) whi...
متن کاملNormalized force, activation, and coactivation in the arm muscles of young and old men.
The purpose of this study was to determine whether the loss of muscle strength in the elderly could be explained entirely by a decline in the physiological cross-sectional area (PCSA) of muscle. Isometric force, muscle activation (twitch interpolation), and coactivation (surface electromyograph) were measured during maximal voluntary contractions (MVCs) of the elbow flexors (EFs) and extensors ...
متن کاملRegulation of myogenin protein expression in denervated muscles from young and old rats.
Myogenin is a muscle-specific transcription factor participating in denervation-induced increases in nicotinic ACh receptor (nAChR) gene expression. Although myogenin RNA expression in denervated muscle is well documented, surprisingly little is known about myogenin protein expression. Therefore, we assayed myogenin protein and RNA in innervated and denervated muscles from young (4 mo) and old ...
