Sources of radioactivity [PDF]

open access: yes, 1964
This report is a summary of Hanford releases to the atmosphere of {sup 131}I, {sup 133}Xe, {sup 135}Xe, and tritium, during the period Sept. 1961 to Dec. 1963. The {sup 131}I released from the two separations plants stacks is measured continuously. Other potential sources of radioiodine to the atmosphere are also monitored, but the release rates from ...

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

open access: yesMolecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.
