Si la plupart des leucémies de types receveurs apparaissent avant celles de types donneurs, c'est parce qu'il faut aux cellules injectées le temps de se différencier, en donnant à partir des cellules souches médullaires des éléments susceptibles de repeupler secondairement la cortical...

Gallstone ileus is a rare cause of small bowel obstruction which usually presents in elderly female patients and which has been associated with high morbidity and mortality rates. We present the case of a 63-year-old man who presented at our institution with symptoms of bowel obstruction. ...
Collisionally activated dissociations (CAD) spectra have been used to investigate the structures of ions produced by decarbonylation of 1-acetylimidazole [1] and acetylpyrazole [12] ionized by electron impact. The results are best explained by the formation of non classical methylene-azolium ions....
The ethyl esters of γ-mono, di- and trichloroaceto-acetic acid and of the γ-mono-, di- and trifluoro compounds have been prepared and investigated with the Infra-red spectrophotometer in order to detect the influence of electronegative substituents on the characteristic functions of the ...
