concluded "that if yellow fever was communicable at all by personal contagion it was so only in an extremely feeble degree". By now, importation by ship was abundantly clearits further elucidation would await the discovery ofmosquito transmission. Buchanan's sanitary measures on the ship and cargo were similar to those of Melier but, in Britain, dependent on local rather than central government...
متن کاملMammalian cell ganglioside-binding specificities of E. coli enterotoxins LT-IIb and variant LT-IIb(T13I).
LT-IIb, a type II heat-labile enterotoxin of Escherichia coli, is a potent immunologic adjuvant with high affinity binding for ganglioside GD1a. Earlier study suggested that LT-IIb bound preferentially to the terminal sugar sequence NeuAcalpha2-3Galbeta1-3GalNAc. However, studies in our laboratory suggested a less restrictive binding epitope. LT-IIb(T13I), an LT-IIb variant, engineered by a sin...

Within the framework of equilibrium statistical mechanics the free energy of a phase gives a measure of its associated probabilistic weight. In order to determine phase boundaries one must then determine the conditions under which the free energy difference (FED) between two phases is zero. The underlying complexity usually rules out any analytical approaches to the problem, and one must theref...
متن کاملF/W e+e- INTERACTIONS*
INTRODUCTION The field of e+e-interactions has provided a great deal of excitement in the past few years. 1-9 Primarily, interest has centered around the reaction +-ee-hadrons. This reaction is particularly attractive because we believe in electromagnetic perturbation theory, which implies that the cross section for hadron production is dominated by one photon annihilation of the electron and p...

The expression of certain CD44 variants has been linked with metastasis and tumour progression. In particular, high molecular weight forms of CD44 show restricted expression in tumours and may correlate with tumour development and metastasis. In this study, we examined the expression of CD44 variants in prostate cancer cell lines: the invasive PC-3 and DU-145, low invasive LNCaP, and two non-in...
