A broad-ranging study of the latest developments in the field of molecular biogerontology, this book examines the many molecular changes which occur during senescence and attempts to pinpoint the fundamental biological pacemakers of aging. Using recombinant DNA technology, investigators examine the importance of DNA damage and the extent of differential gene expression during aging. Attempts to manipulate the lifespans of various model organisms through gene transfer and regulated gene expression are also discussed. The involvement of viruses in the aging process, molecular approaches to age-related diseases and metabolic aspects of cell death such as the role of oxygen in free-radical toxicity have been examined by eminent researchers in the field. Throughout the text, contributors stress that the genome holds the ultimate key to understanding the limitations of lifespan and the determinants of senescence.
黃體持續分泌黃體酮的時間約有 10 周,此時的功能是促進胎盤發育。整個孕期中,黃體酮可以穩定子宮,避免子宮收縮造成流產。如果卵巢排出的卵未能受精,黃體便會開始退化,不再分泌黃體酮,新的月經周期也準備到來。胎盤(西元1651年);卵巢及雌性生殖(西元1900 ...
