Other Luminous Organisms

Any system designed to detect colonic polyps may potentially detect polypoid objects that have soft-tissue CT density and protrude into the lumen. Therefore, any polypoid soft-tissue structure in the small bowel, stomach, or even the lungs can he erroneously detected as a polyp. Thus, the first step of CAD after reading in the CTC images is the extraction of the colonic wall while removing other luminal organs with soft-tissue density, such as the small howel, stomach and lung bases. 

Distribution of luminous bacteria. Luminous bacteria are widely distributed in the marine environment, and have been isolated from various sources, including seawater, the light organs and various other parts of marine luminous organisms, sometimes even from nonmarine sources as well. There are several major groups of luminous bacteria... 

When an alkene (or any other unsaturated organic compound) is burned in air, a yellow, luminous flame is observed, and considerable soot (unbumed carbon) is formed. This reaction provides a qualitative test for unsaturation. Saturated hydrocarbons bum in air without forming significant amounts of soot. 

Hydrochlorothiazide, indapamide, and metolazone (and many others) are organic adds that are both filtered and secreted and that inhibit the Na+/CP cotransporter on the luminal membrane f the distal convoluted tubule (DCT). 

The agents for bioluminescent assays are luminous bacteria, recombinant luminous organisms, luciferases and others enzymes for multienzymatic bioluminescent assays. The extremely high amplification of these luminescent systems allows rapid methods to be set up which can be applied to a very small amounts of biological samples. The sensitivity of these methods is often at the nanomolar level, on the border between conventional enzymatic and immunological methods. Moreover they are applicable to analytes present at very low concentration and when high sensitivity is not required, analysis time can be reduced to few seconds. ...
