Repeat and single dose administration of gadodiamide to rats to investigate concentration and location of gadolinium and the cell ultrastructure

Scientific Reports, 2021
Gadolinium based contrast agents (GBCA) are used to image patients using magnetic resonance (MR) imaging. In recent years, there has been controversy around gadolinium retention after GBCA administration.

3D reconstruction of skin and spatial mapping of immune cell density, vascular distance and effects of sun exposure and aging

Communications Biology, 2023
Mapping the human body at single cell resolution in three dimensions (3D) is important for understanding cellular interactions in context of tissue and organ organization. 2D spatial cell analysis in a single tissue section may be limited by cell numbers

CRYSTALLIZATION OF AMORPHOUS Ge IN Ge/Au, Ge/Ag BILAYER FILMS AND Ge-Au, Ge-Ag ALLOY FILMS

Acta Physica Sinica, 1986
In this article, as-evaporated and annealed samples of Ge/Au, Ge/Ag bilayer films and Ge-Au, Ge-Ag alloy films were investigated by TEM. In situ observations of Ge/ polyerystalline Au (p-Au) and Ge/p-Ag films during heating were also made by TEM. It is found that crystallization temperature Tc of amorphous Ge (a-Ge) in a-Ge/p-Au is much lower than Tc ...
