Measuring sustainable consumer food purchasing and behavior.

Consumer food purchasing and willingness to adopt a sustainable healthy diet (SHD) is a key factor affecting the sustainability of the entire food system. Studies have developed scales to measure consumer preferences for particular consumption patterns, while others have sought to empirically define the multiple dimensions of a sustainable food system (environmental, social, economic, etc.).

Bacteriophage 933W encodes a functional esterase downstream of the Shiga toxin 2a operon.

In this study, the 1938bp open reading frame z1466, which is encoded directly downstream the Shiga toxin 2a (Stx2a) operon in E. coli O157:H7 phage 933W was cloned and expressed recombinantly. Purification with Ni-NTA agarose beads with subsequent SDS-PAGE revealed a 68kDa protein, designated 933Wp42-His.

Growth media simulating ileal and colonic environments affect the intracellular proteome and carbon fluxes of enterohemorrhagic Escherichia coli O157:H7 strain EDL933.

In this study, the intracellular proteome of Escherichia coli O157:H7 strain EDL933 was analyzed by two-dimensional gel electrophoresis and matrix-assisted laser desorption ionization-time-of-flight (MALDI-TOF) spectrometry after growth in simulated ileal environment media (SIEM) and simulated colonic environment media (SCEM) under aerobic and microaerobic conditions. Differentially expressed intracellular proteins were identified and allocated to functional protein groups. Moreover, metabolic fluxes were analyzed by isotopologue profiling with [U-(13)C(6)]glucose as a tracer.

High-resolution phonon study of the Ag(100) surface.

Using high-resolution electron energy loss spectroscopy the phonon dispersion of Ag(100) has been studied at two different sample temperatures of 86 and 300 K. The dominant feature in the spectra corresponds to the Rayleigh wave. Its full dispersion is determined along the ΓX high symmetry direction in the first and second Brillouin zones.

The use of clinical CCT images in the forensic examination of closed head injuries.

The forensic evaluation of clinical cranial computed tomographies (CCT) frequently is the only reliable source of morphological evidence in head injuries when the injured individual survives or when death is delayed and autopsy findings are characterized by secondary changes. We have reviewed 21 cases where clinical CCT examinations were used to establish a medico-legal diagnosis. In 18 cases falls (n = 13) could be distinguished from blows (n = 5) due to the presence and/or absence of coup and contrecoup lesions and linear or depressed skull fractures.
