Inorganic chemistry

Gregoliński J, Hikita M, Sakamoto T, Sugimoto H, Tsukube H, Miyake H.
PMID: 26731008
Inorg Chem. 2016 Jan 19;55(2):633-43. doi: 10.1021/acs.inorgchem.5b01902. Epub 2016 Jan 05.

Three chiral ligands with variable denticity, H2L2-H2L4, conjugated by N,N'-ethylenebis[N-methyl-(S)-alanine] and an ortho-heterosubstituted aromatic amine, were newly synthesized as analogues of previously reported H2L1. Four contracted-Λoxo cobalt(III) complexes [Co(L)](+) with left-handed helical structure of Λ4Δ2 configuration were prepared by...

Can high dose rates used in cancer radiotherapy change therapeutic effectiveness?.

Contemporary oncology (Poznan, Poland)

Contemp Oncol (Pozn). 2016;20(6):449-452. doi: 10.5114/wo.2016.65603. Epub 2017 Jan 12.

Current cancer radiotherapy relies on increasingly high dose rates of ionising radiation (100-2400 cGy/min). It is possible that changing dose rates is not paralleled by treatment effectiveness. Irradiating cancer cells is assumed to induce molecular alterations that ultimately lead...
