Current methods to detect the colonization factor antigens (CFAs) associated with enterotoxigenic Escherichia coli (ETEC) strains are cumbersome, with some methods requiring antibodies that are not readily available. To achieve a gene-based method, we designed 2 multiplex polymerase chain reaction reactions to detect genes encoding the most common ETEC fimbrial colonization factors, including C...

Radiative transfer-scattering models were used to fit the Hubble Space Telescope UV spectroscopic observations of Jupiter taken 2.5 hours after the impact of fragment G of comet P/Shoemaker-Levy 9. They yield abundances for NH3 and CS2 of (0.25-1.3)x1016cm -2 and (0.43-1.1)x1015cm -2, respectively, at unit optical depth level in the part of the atmosphere above the G-impact site. This range in ...

The present research examined the temporal distribution of responding in a lick suppression paradigm. In Experiment 1, rats were trained with either a 30- or a 120-s conditioned stimulus (CS), which was followed either by a footshock (unconditioned stimulus [US]) or nothing. Licking during the CS was suppressed only in the former condition. Suppression was more pronounced early in the CS. In Ex...

The expression of a winged-helix transcription factor, Foxa2/HNF3beta, is essential for development of the node and the notochord. We examined the node/notochord enhancer of mouse Foxa2 for sequence motifs conserved across vertebrate species. We cloned Foxa2 genes from chicken and fish, and identified the respective node/notochord enhancers that were active in transgenic mouse embryos. Comparis...

In the group of 37 patients with chronic carbon disulphide (CS2) intoxication manifested by encephalopathy, polyneuropathy or psycho-organic syndrome and complaining for vertigo, a statokinesiometric test was performed with open and closed eyes, and with visual stimulation. Basic test parameters of stabilograms and statokinesiograms were compared with standard values of the control group. Resul...

The Directional Recoil Identification From Tracks (DRIFT) detector has recently been proposed [?] to search for dark matter. This detector is unique in that it drifts negative ions, instead of electrons, in a time projection chamber (TPC). A detailed description of the operation, motivation, and other uses of a negative ion TPC (NITPC) can be found in [?]. Briefly, an electronegative component ...

Molecular dynamics simulation studies were performed to investigate the structural and dynamic properties of liquid carbon disulfide (CS2) from ambient to elevated pressure conditions. The results obtained have revealed structural changes at high pressures, which are related to the more dense packing of the molecules inside the first solvation shell. The calculated neutron and X-ray structure f...

In this paper we report the measurement of the direct fifth-order electronically nonresonant intermolecular response from liquid CS2 at room temperature. We recently demonstrated that all previous attempts to measure the direct fifth-order response were dominated by third-order cascaded signals @J. Chem Phys. 111, 3105 ~1999!#. Here we show that phase matching considerations can be used to prov...
