延缓衰老新突破

1. Mr. Chen appeared to be a man of distinction, yet he seemed to have aged prematurely, like a gentleman from a bygone era. 2. An abnormal number of holly trees displayed withered branches or trunks, indicating their senescence. 3. The study revealed the presence of amitotic phases and cellular senescence traits in adult goat ventricular muscle cells, including working and conducting cardiac muscle cells. 4. I may be aging, but I am not yet senile. 5. I may be aging, but I am not yet senile. 6. The drug seemed to eliminate only senescent cells, leaving normal cells unharmed, and the animals did not exhibit any adverse effects, according to the researcher. 7. Initially, the researchers removed senescent cells from mice throughout their lives, administering the drug every three days, starting from when the animals were weaned. 8. There are two mechanisms for removing senescent red blood cells; both conserve the primary components of the cell for reuse. 9. Senescent cells are mitotic cells that can no longer divide but remain metabolically active. Senescence is often caused by stimuli that can lead to cancer. 10. The objective was to investigate the proliferative and senescent patterns of adult goat ventricular muscle cells. 11. The clearance of senescent cells in those mice did not reverse the existing decline but prevented further deterioration. 12. Senescent cells make up only a small portion of cells, approximately 5% or less, in the tissue of elderly individuals, but their impact can be widespread, as researchers have observed. 13. The senescent chondrocytes were distributed in the central zone, where apoptotic morphological characteristics, such as pyknosis and karyorrhexis, were clearly evident. 14. The objective was to explore the relationship between senescent red blood cell deformability and lipid composition, as well as spectrin content (SP) in the erythrocyte membrane. 15. When cells become senescent, they produce harmful compounds, such as those that cause inflammation. 16. His assignment was to portray coal as a developing industry rather than a senescent one. 17. I halted my步伐，目瞪口呆地看着其他步履蹒跚的行人从这个维度中离开。 18. Researchers at the Mayo Clinic in Rochester, Minnesota, discovered for the first time that by using a drug to target and eliminate senescent cells, they could effectively slow down certain aspects of the aging process. 19. The study suggested that ILK might be involved in the fibrotic process or senescent process in aging kidneys. 20. However, he warns that further research is needed to understand the effects of removing senescent cells. 21. When the researchers administered the drug to the mice, the death pathway was activated in all senescent cells. 22. The Vicia sativa root nodule is typically rod-shaped, mainly composed of numerous cortex cells and a vast central zone containing meristem, infected tissue, and senescent tissue. 23. "Our method allowed us to observe the consequences of removing senescent cells at different stages of the mouse life cycle," van Deursen said. "We didn't just block senescence entirely." 24. The story began with an observation made a few years ago that senescent cells often produce a molecule called P16INK4A. 25. Van Deursen and colleagues developed a method to kill senescent cells in mice, clearing them from the body. 26. As red blood cells age, they may undergo antigenic changes, acquiring senescent antigens and losing flexibility due to impaired ATP production. 27. A cell that has stopped dividing is known as senescent; it continues to live but no longer functions as it once did. 28. The key, they reported in a captivating new study, is eliminating senescent cells from the body – old "zombie" cells that no longer function properly. 29. In elderly humans, it is believed that at least 5% of the total cells in the body are senescent. These cells accumulate in areas particularly affected by aging, such as the eyes and muscles. 30. The scientists initially genetically engineered mice to have a specific molecule in their senescent cells.
