If the S. latifolia did not practice dosage compensation, the expected level of X-linked gene expression in males would be 50% that of females, thus the plant practices some degree of dosage compensation but, because male expression is not 100% that of females, it has been suggested that S. latiforia and its dosage compensation system is still ...

Gain of an X chromosome, [20] Klinefelter syndrome, [21] and XX male syndrome [22] are risk factors linked to male breast cancer. In females, there is no evidence that trisomy X or tetrasomy X females are at higher risk of cancer. [19] Breast cancer and ovarian cancer, particularly more aggressive strains, commonly lack an Xi and have two Xa's ...
However, this pattern has been proven wrong for many cancer types, suggesting that some cancers may be polyclonal in origin. [46] Besides, measuring the methylation (inactivation) status of the polymorphic human androgen receptor (HUMARA) located on X-chromosome is considered the most accurate method to assess clonality in female cancer ...
Stevens never had cancer; a surgery to remove cancerous cells was highly successful in removing the benign tumor, and he lived for another 20 years with the injected plutonium. [76] Since Stevens received the highly radioactive Pu-238, his accumulated dose over his remaining life was higher than anyone has ever received: 64 Sv (6400 rem ...

The first-in-human tests of a potential treatment are called Phase I studies. Early clinical trials typically enroll a very small number of patients, and the purpose is to identify major safety issues and the maximum tolerated dose , which is the highest dose that does not produce serious or fatal adverse effects .
The good news is that due to increased screening, cervical cancer incidence has been falling, but it is still at 7 per 100,000 and the death rate is 2.2 per 100,000 women.
