Oxidative stress in hypopituitary dwarf mice and in transgenic mice overexpressing human and bovine GHSpringer Science and Business Media LLC - Tập 22 - Trang 181-186 - 1999

Growth hormone (GH) stimulates metabolic activity. The purpose of this study was to examine whether it is involved in the aging process by increasing oxidative stress. Inorganic peroxides and lipid peroxides were measured in kidney and liver samples in dwarf mice that are deficient in GH, prolactin and thyrotropin and in transgenic mice that produce high levels of GH. In normal male mice, there wa...... hiện toàn bộ
Wild-derived mouse stocks: an underappreciated tool for aging researchSpringer Science and Business Media LLC - Tập 30 - Trang 135-145 - 2008
James M. Harper
Virtually all biomedical research makes use of a relatively small pool of laboratory-adapted, inbred, isogenic stocks of mice. Although the advantages of these models are many, there are a number of disadvantages as well. When studying a multifaceted process such as aging, the problems associated with using laboratory stocks are greatly inflated. On the other hand, wild-derived mouse stocks, loose...... hiện toàn bộ
Songbirds: A novel perspective on estrogens and the aging brainSpringer Science and Business Media LLC - Tập 27 - Trang 287-296 - 2006
Barney A. Schlinger, Colin J. Saldanha
Songbirds perform some remarkable feats of memory, including forming memories for songs and for complex spatial features of their environments. Research into the neural and hormonal control of these behaviors reveals discrete circuits that can retain considerable plasticity in adulthood. The songbird brain is also a prominent site of estrogen synthesis and a target of estrogen action. Estrogens co...... hiện toàn bộ
Circadian clock resetting in the mouse changes with ageSpringer Science and Business Media LLC - Tập 31 - Trang 293-303 - 2009
Stephany M. Biello
The most widely recognised consequence of normal age-related changes in biological timing is the sleep disruption that appears in old age and diminishes the quality of life. These sleep disorders are part of the normal ageing process and consist primarily of increased amounts of wakefulness and reduced amounts of deep sleep. Changes in the amplitude and timing of the sleep-wake cycle appear to rep...... hiện toàn bộ
