BACKGROUND In vivo bioluminescence imaging (BLI) is a powerful method for the analysis of host-pathogen interactions in small animal models. The commercially available bioluminescent Listeria monocytogenes strain Xen32 is commonly used to analyse immune functions in knockout mice and pathomechanisms of listeriosis. FINDINGS To analyse and image listerial dissemination after oral infection we ...

In a randomized, parallel design, 19 patients with winter depression were treated with either a week of a white 1.5-hr dawn simulation peaking at 250 lux or a week of a red, 1.5-hr dawn signal peaking at 2 lux. The subjects were told that they would receive either a white or red dawn reaching in intensity that would be dimmer than standard bright light treatment. At the end of both the baseline...

When tested in Hirsch-Hadler mazes, Drosophila pseudoobscura descended from natural populations is phototactically and geotactically neutral on the average. Decidedly positive and negative populations have been obtained by artificial selection. The behavior is independent of temperature (15-27 degrees ) and age (2-17 days). The flies perceive light as weak as 0.2 lux; from 7 to 3000 lux the beh...

Accidents caused by malfunctioning of the brake light system are increasing in line with rise road facilities. It provides space for drivers to drive vehicles quickly. To overcome this problem, a that can signal driver must rapidly identify damaged lights. The purpose study was produce car indicator tool. This tool is an electronic device functions determine when one lights off automatically gi...

Quantitative RT-PCR using LUX primers was performed to determine the expression patterns of various transcripts in samples of pluripotent, mouse P-19 stem cells. The P-19 cells were used because they transform into neuron-like cells upon retinoic acid treatment. The expression of neural and stem cell genes, including GLUR1, GABA-B1a, NMDA1, GAP-43, ChAT, BDNF, nestin, BMP-2, BMP-4, and EGR1, wa...
