Distinctive profiles of infection and pathology in hamsters infected with Clostridium difficile strains 630 and B1.

Currently, the Golden Syrian hamster is widely considered an important model of Clostridium difficile disease, as oral infection of this animal pretreated with antibiotics reproduces many of the symptoms observed in humans. Two C. difficile strains, B1 and 630, showed significant differences in the progression and severity of disease in this model.

Primary renal non-Hodgkins lymphoma presenting with acute renal failure.

Primary renal lymphoma (PRL) has been reported in medical literature. Its occurrence is rare and controversial, the kidney being an extranodal organ. We report a case of primary renal lymphoma presenting with acute-on-chronic renal failure and unilateral involvement of the left kidney without obstruction and with minimal peripheral organ involvement.

Visible-regime polarimetric imager: a fully polarimetric, real-time imaging system.

A fully polarimetric optical camera system has been constructed to obtain polarimetric information simultaneously from four synchronized charge-coupled device imagers at video frame rates of 60 Hz and a resolution of 640 x 480 pixels. The imagers view the same scene along the same optical axis by means of a four-way beam-splitting prism similar to ones used for multiple-imager, common-aperture color TV cameras. Appropriate polarizing filters in front of each imager provide the polarimetric information.
