Prevention of Radiation-Induced Telomere Shortening, A Novel Mechanism Underlying Low-Dose Arsenic-Mediated Protection of Normal T-Lymphocytes

wuthering heights and the concept of marality/a sociological study of the novel

to discuss my point, i have collected quite a number of articles, anthologies, and books about "wuthering heights" applying various ideas and theories to this fantastic story. hence, i have come to believe that gadamer and jauss are rightful when they claim that "the individaul human mind is the center and origin of all meaning," 3 that reading literature is a reader-oriented activity, that it ...

The shortening telomere length of T lymphocytes maybe associated with hyper-function in servere aplastic anemia

Severe aplastic anemia (SAA) is a primary disorder of severe bone marrow failure characterizing with extreme pancytopenia and a profound diminution of bone marrow progenitor cells, which is associated with T cell hyper‑function. Abnormal telomere shortening of bone marrow mononuclear cell has been reported in AA, which may lead to genomic instability, and result in cell senescence or apoptosis....

Telomere shortening triggers a feedback loop to enhance end protection

Telomere homeostasis is controlled by both telomerase machinery and end protection. Telomere shortening induces DNA damage sensing kinases ATM/ATR for telomerase recruitment. Yet, whether telomere shortening also governs end protection is poorly understood. Here we discover that yeast ATM/ATR controls end protection. Rap1 is phosphorylated by Tel1 and Mec1 kinases at serine 731, and this regula...

Effects of N-acetylcysteine on life shortening induced by chronic low dose-rate gamma-ray exposure in mice

Background: The development of methods to alleviate radiation-induced health effects is important for the practical use of radiation therapy and for understanding the molecular mechanisms mediating these effects. Here, we examined the protective capability of N-acetylcysteine (NAC) on life-shortening effects induced by continuous low dose-rate gamma-ray exposure in mice. Materials and Methods: ...
