Abstract:The absorption and emission of light by biological systems is a dilemma for the research community which remains transfixed upon the bottom-up systems biology approach. Many health care professionals do not yet accept that photosensitivity is an essential aspect of the body's function.This article highlights that light is often required to activate enzymes and/or proteins in biological systems. Inadequate levels of exposure to light may be responsible, at least in part, for the uncoiled nature of proteins found in diabetes mellitus, Alzheimer's disease, and other conditions. Moreover the emission of light, the consequence of protein reactions with reactive substrates or of reactive oxygen species, is an often observed characteristic of pathologies and influences the visual perception of colour. It illustrates that a significant diagnostic principle exists by measuring the levels of light absorbed and/or the bioluminescence released from fluorescent pathologies.

“…(Alexander Gurwitsch, V.P.Kazmacheyev and others established that every living cell emits light). Most proteins are visually active and/or naturally bioluminescent [136,137]. A similar principle appears to be used in non-linear interferometric vibrational imaging [139,140] which, like Virtual Scanning, has taken many years to be developed.…”

“…Barnett et al 1969;Burkard et al 1972;Hug et al 1980;Wanka and Aelen 1973). According to some authors (Kinoshita et al 1979;R/tcz et al 1978) light seems to have an important regulatory role on RNA composition of higher plants, causing marked changes in the amounts of some isoacceptor tRNAs and in the appearance of minor nucleotides in ribosomal and transfer (t)RNAs.…”

The contents in minor nucleotides of total transfer RNA (tRNA) of etiolated and light-grown wheat (Triticum aestivum L.) seedlings and of seedlings illuminated for 24 or 48 h were examined. The total tRNA of seedlings illuminated 24 h contained more, and that from seedlings illuminated 48 h still more modified nucleotides than that from etiolated ones. Thus, the appearance of the characteristic minor nucleotides of tRNA of light-grown wheat seedlings needs a rather long greening period, of at least 48 h.

“…Therefore it is not surprising that in recent years several reviews have dealt with the effect of light on enzymes [2,8,23,24,25,41,42,68,73,89]. However, strangely enough, the specific influence of the blue light (BL) photoreceptors has been neglected to some extent.…”
