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 ...
Committed effective dose, is the sum of the products of the committed organ or tissue equivalent doses and the appropriate tissue weighting factors W T, where t is the integration time in years following the intake. The commitment period is taken to be 50 years for adults, and to age 70 years for children. [3]
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 ...
Surviving the highest known radiation dose in any human Albert Stevens (1887–1966), also known as patient CAL-1 and most radioactive human ever , was a house painter from Ohio who was subjected to an involuntary human radiation experiment and survived the highest known accumulated radiation dose in any human.

Available data describes a wide range of doses used in the experiments, from approximately 2μg/kg to 16μg/kg [33] A typical dose for recreational use is around 100μg, [38] [39] [40] or about 1.1μg/kg for the average adult male in the U.S., [41] meaning the lowest dose used in experimentation was almost twice the typical recreational dose ...
Ionizing radiation has deterministic and stochastic effects on human health. The deterministic effects that can lead to acute radiation syndrome only occur in the case of high doses (> ~10 rad or > 0.1 Gy) and high dose rates (> ~10 rad/h or > 0.1 Gy/h).
The linear no-threshold model (LNT) is a dose-response model used in radiation protection to estimate stochastic health effects such as radiation-induced cancer, genetic mutations and teratogenic effects on the human body due to exposure to ionizing radiation. The model assumes a linear relationship between dose and health effects, even for ...
