A 55-year-old woman was admitted to our hospital, complaining of general malaise, muscular weakness, anorexia and weight loss. She had a history of ingesting of a certain germanium (Ge) compound over the preceding 19 months, with a total dose of
R M Slawson et al.
Plasmid, 27(1), 72-79 (1992-01-01)
Germanium is an inert metal with no known biological function in prokaryotic or eukaryotic organisms. Its toxicity is low compared to that of silver. Germanium is accumulated in certain bacterial strains by either energy-independent passive binding or an energy-dependent mechanism.
A G Schauss
Biological trace element research, 29(3), 267-280 (1991-06-01)
There is no known biological requirement for germanium (Ge), germanates, or any organogermanium compound. Ge deficiency has not been demonstrated in any animal. The estimated average dietary intake of Ge in humans is 1.5 mg/d. Ge is widely distributed in
Rackel Reis et al.
ACS applied materials & interfaces, 7(27), 14644-14653 (2015-06-18)
Thin-film composite membranes, primarily based on poly(amide) (PA) semipermeable materials, are nowadays the dominant technology used in pressure driven water desalination systems. Despite offering superior water permeation and salt selectivity, their surface properties, such as their charge and roughness, cannot
S H Tao et al.
Regulatory toxicology and pharmacology : RTP, 25(3), 211-219 (1997-06-01)
Germanium-containing dietary supplements became popular in the 1970s in Japan and later in other countries, as elixirs for certain diseases (e.g., cancer and AIDS). Germanium is not an essential element. Its acute toxicity is low. However, at least 31 reported
