Energy-deficient

Herkstroeter and Hammond found support for this postulate from a flash photolysis study. They were able to measure directly the rate of sensitizer quenching (energy transfer) by cis- and fra/w-stilbene. When a sensitizer triplet had insufficient excitation energy to promote fims-stilbene to its triplet state, the energy deficiency could be supplied as an activation energy. The decrease in transfer rate as a function of excitation energy of the sensitizer is given by...

In energy-deficient systems triplet-triplet annihilation is involved. This was proved by several experimental facts. 

Chemically inert triplet quenchers e.g. trans-stilbene, anthracene, or pyrene, suppress the characteristic chemiluminescence of radical-ion recombination. When these quenchers are capable of fluorescence, as are anthracene and pyrene, the energy of the radical-ion recombination reaction is used for the excitation of the quencher fluorescence 15°). Trans-stilbene is a chemically inert 162> triplet quencher which is especially efficient where the energy of the first excited triplet state of a primary product is about 0.2 eV above that of trans-stilbene 163>. This condition is realized, for example, in the energy-deficient chemiluminescent system 10-methyl-phenothiazian radical cation and fluoranthene radical anion 164>. 

Energy-deficient radical-ion reactions generally exhibit low quantum yields due to the rather circumstantial triplet-triplet annihilation mechanism 150>. 

Two main CL pathways are then possible If sufficient energy is available, an electron transfer reaction where the singlet excited state of A is accessible (3) otherwise an energy-deficient route whereby the energy from two triplet excited-state species are pooled, to provide sufficient energy to form the singlet excited state, in what is termed a triplet-triplet annihilation reaction, (4) and (5).

Presently photodynamic therapy (PDT) is considered as a perspective way for therapy of different diseases, including cancer. PDT is a method based on the local light-induced activation of photosensitizers able to accumulate selectively in energy-deficient cells (malignant or dysplastic ones) not influencing the remaining normal cells of the body (Pass, 1993). Upon the action of irradiation of certain wavelength characteristic for individual photosensitizer, photochemical reaction occurs... 

Experiments on small experimental animals suggest that ovemutrition per se may reduce lifespan experimental animals fed on energy-deficient diets live longer than those on control diets. An explanation for this is awaited with interest. 

In normal young children, the contribution of amino acid oxidation to energy requirement in starvation is about 1%, similar to that in the obese. In malnourished children, who have a protein-energy deficiency, it is even lower (4%). This suggests that a mechanism exists to protect muscle protein from degradation in children. Such a mechanism may involve a faster and greater increase in ketone body formation in children compared with adults (Chapter 7).

The reaction is allosterically inhibited by high concentrations of AMP, an indicator of an energy-deficient state of the cell. 

The primary requirement of a chemiluminescent reaction is that it should be energy-sufficient. If the energy of the reaction is not enough to promote the product to first excited singlet state, the system is said to be energy-deficient and molecules in the triplet states may be formed. In such cases triplet-triplet annhilation of initially generated triplets may populate an excited singlet state.

First, the free energy change AG873 of the primary reaction (4.2) equal 246.4kJ/mol fully compensates for the free energy deficiency in the secondary reaction. For this purpose, let us calculate AGg73 at test temperatures for each of the following reactions ... 

People with Multiple Chemical Sensitivity become ill as soon as they are exposed to specific chemicals (smoke, perfume, cleaning products, et cetera). This is often caused by a problem in their detoxification system (sometimes caused by DNA defects) and/or for example short and long time chemical (over) exposure (think of the many firefighters who got ill after September 11 or of soldiers with Gulf War syndrome). Reiki cannot solve this problem, but it can support both the physical and mental processes and the energy deficiency that often occurs in this syndrome. A combination of remedies is best to try and improve the condition avoid the chemical stimuli, eat biological food, use food supplements to support detoxification, exercise, meditate and use Reiki (see www.the-abc-of-mcs.com for more information about this disease).
