Unique transport paths of Cs from the Indian to Southern Oceans.

To assess ocean-scale transport systems, we examined the latitudinal cross-sectional distribution of Cs activity concentrations in the Indian and Southern Oceans between December 2019 and January 2020 using low-background γ-spectrometry. At 0°-20°S, Cs concentrations exhibited a gradual decrease below the mixing layer (1-0.1 mBq/L).

Subarctic-scale transport of Cs to ocean surface off northeastern Japan in 2020.

We studied the spatiotemporal variations in Cs, Cs, and Ra concentrations at the sea surface off southeastern Hokkaido, Japan (off-Doto region) from 2018 to 2022 using low-background γ-spectrometry. The Cs concentrations in the off-Doto region, decay-corrected to the date of the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident, exhibited wide lateral variation each year (e.g.

Origin of surface water in the Southern Ocean: Implications of soluble radionuclide distributions.

Concentration data of soluble radionuclides in the southern South Indian Ocean and Southern Ocean transition zone are rare or insufficient for the study of its current system. We examined the lateral surface variations in soluble natural (Ra and Ra) and anthropogenic (Cs and Cs) radionuclide activity concentrations in the surface waters in this area from November 2021 to March 2022. The surface distributions of Ra and Cs concentrations were classified into Subantarctic Mode Water-, Antarctic Intermediate Water-, and Upper Circumpolar Deep Water (UCDW)-dominated areas along latitudinal band (40°S-65°S, 110°E-120°E).

Granulocyte colony-stimulating factor-associated aortitis in a woman with breast cancer: a case report.

Background: Granulocyte colony-stimulating factor (G-CSF) is increasingly used to prevent chemotherapy-associated febrile neutropenia. Generally, aortitis is not considered a side effect of G-CSF and is thought to be extremely rare. Aortitis is an inflammation of the aorta and occurs mainly in connective tissue diseases (Takayasu arteritis, giant cell arteritis, etc.

Transport paths of radiocesium and radium isotopes in the intermediate layer of the southwestern Sea of Okhotsk.

The spatial distributions of Cs, Cs, Ra, and Ra in/around the southwestern Sea of Okhotsk were examined in July 2019 and July 2021. Wide variations in the concentrations of these radionuclides were detected at the surface, including 0.2-0.
