senescence

基本解釋

Many researchers think senescence-related tissue dysfunction contributes to heart disease and cancer and other conditions that become more likely with age.
許多研究者認為，同衰老相關的器官組織停止運作，這點會導致心臟病和癌癥以及其它老年病的發(fā)生。
Instead, they reach a state of limbo scientists call cellular senescence, in which they no longer divide but release substances that damage adjacent cells and cause inflammation.
相反，它們遭到遺棄，科學家們稱之為細胞衰老，它們不再分裂而是釋放物質損害相鄰細胞并導致炎癥。
Conversely, if telomerase activity is high, telomere length is maintained, and cellular senescence is delayed. This is the case in cancer cells, which can be considered to have eternal life.
相反，如果端粒酶一直保持較高的活力，則端粒的長度就能保持下去，而細胞衰老的進程就會被推遲，這種情形可見于癌細胞：一類屬于永生的細胞。

As Margaret Thatcher in old age—confined to her home and afflicted with dementia—Meryl Streep turns senescence into poetry.

Other work—on the effects of caloric restriction, consuming red wine and altering genes in yeast, mice and nematodes—has shown promise in slowing senescence.
ECONOMIST: The latest from the wacky world of anti-senescence therapy
Research shows that exercise can help to maintain physical function late in life and that exercising one's brain can limit the progression of senescence.

the fact of becoming older, and therefore being in less good condition and less able to function well

衰老
The pH value in pericarp increased slowly along with the senescence.
衰老過程中,果皮pH值緩慢上升。
早衰
Phenomenon of premature senescence be serious, lodging percentage been decreased, ability of utilization and interception of light been decreased.4.
由此可見,晚播處理早衰現象嚴重,倒伏的幾率高,光能截獲能力弱,光能利用率低。

衰老
Delaying senescence is the everlasting dream for everyone.
延緩衰老、頤養(yǎng)天年是人類夢寐以求的愿望。
老化
The state of senescence should be considered for culture expanded MSCs when they are used for study.
在應用體外擴增后MSCs進行研究時需考慮細胞老化的狀態(tài)。
