CDs are also used to stabilize sensitive substances to light or oxygen [44], proteins [45], nanoparticles [46], and add value addition of taste and colour of toothpaste [44].
These QDs appear to be promising candidates for biomedical applications such as drug delivery for enhanced chemotherapy or targeted delivery of light sensitive substances for photodynamic therapy.
Aside from controlling release, LC phases can also be used for protecting sensitive substances such as peptides and proteins from enzymatic degradation, and for solubilization of sparingly soluble compounds into the lipid and/or aqueous nano-domains.
In 1895 he found that two components of blood serum are responsible for the rupture of bacterial cell walls (bacteriolysis): one is a heat-stable antibody found only in animals already immune to the bacterium; the other is a heat-sensitive substance found in all animals that was named alexin (it is now called complement).
Calcitonin gene-related peptide (CGRP) in capsaicine-sensitive substance P –immunoreactive sensory neurons in animal and man: distribution and released by capsaicin2] Naunyn Schmiedeberges' Arch Phrmacol.1988; 337, 6:, 649-53.
One sample was weakly reactive to human leptospirosis (indirect hemagglutination assay with erythrocyte-sensitive substance antigen [Labiofam, Havana, Cuba]), but no samples were reactive to syphilis (rapid plasma reagin [Imefa, Havana, Cuba] and hemagglutination of Treponema pallidum [Oxoid, Diagnostic Reagents, Basingstoke, UK]).
He coated pewter with various light-sensitive substances in an effort to copy superimposed engravings in sunlight.
They sell it as a natural, non-invasive therapy, using non-toxic light-sensitive substances such as chlorophyll which "explode" with oxygen, killing the cancer cells when activated not only by light but also by ultrasound waves which, they say, can reach every part of the body.
Together, these data demonstrate that not only can GRPR expression transform cells, but these cells then become more sensitive to substance P-analogue-induced cell death.
