Vibrio parahaemolyticus, enterotoxigenic Escherichia coli, enterohemorrhagic Escherichia coli and Vibrio cholerae
This review highlighted the following: (i) pathogenic mechanism of the thermostable direct hemolysin produced by Vibrio parahaemolyticus, especially on its cardiotoxicity, (ii) heat-labile and heat-stable enterotoxins produced by enterotoxigenic Escherichia coli, especially structure–activity relationship of heat-stable enterotoxin, (iii) RNA N-glycosidase activity of Vero toxins (VT1 and VT2) produced by enterohemorrhagic Escherichia coli O157:H7, (iv) discovery of Vibrio cholerae O139, (v) isolation of new variant of Vibrio cholerae O1 El Tor that carries classical ctxB, and production of high concentration of cholera toxin by these strains, and (vi) conversion of viable but nonculturable (VBNC) Vibrio cholerae to culturable state by co-culture with eukaryotic cells

Preparation and structure of iminopyrrolyl and amidopyrrolyl complexes of group 2 metals
Reactions of N-aryliminopyrrolyl ligand 1a, 2-(2,6- iPr 2C 6H 3N=CH)-C 4H 3NH (Imp Dipp-H), with dibenzylcalcium gave two types of pyrrolylcalcium complexes, bis(iminopyrrolyl)calcium (2a) and (amidopyrrolyl)calcium (3a), via alkane elimination and ligand alkylation reaction, respectively. Preparation of a mono(iminopyrrolyl) complex, (iminopyrrolyl)Ca[N(SiMe 3) 2](THF) 2 (4a), was accomplished by the addition of 1 equiv of 1a to Ca[N(SiMe 3) 2] 2(THF) 2. A series of group 2 metal bis(iminopyrrolyl) complexes, [(Imp Dipp) 2M(THF) 3] (M = Sr (5a), Ba, (6a)) and [(Imp Me) 2Ca(THF) 2] (2b) (2-(4-MeC 6H 4N=CCH 3)-C 4H 3NH (Imp Me-H)), was selectively prepared via amine elimination reactions, and their molecular structures were clarified by X-ray diffraction studie
