Drug delivery with carbon nanotubes for in vivo cancer treatment [PDF]
Cancer Res. 68 (2008) 6652-6660, 2008 Chemically functionalized single-walled carbon nanotubes (SWNTs) have shown promise in tumor targeted accumulation in mice and exhibit biocompatibility, excretion and little toxicity. Here, we demonstrate in-vivo SWNT drug delivery for tumor suppression in mice.

Fate of nitrogen in French human excreta: current waste and agronomic opportunities for the future [PDF]
arXiv, 2023 Nitrogen (N) is essential for plant growth and protein synthesis but global reactive N losses, mainly from food systems, induce strong environmental impacts.N losses after human excretion are often overlooked because, in Western societies, they partly occur as inert N2, following denitrification in wastewater treatment plants (WWTP), and losses in ...
