Ultraweak photon emission emitted by all living organisms has been confirmed to be a noninvasive indicator for their physiological and pathological characteristics. In this study, we investigated the characteristics of spontaneous photon emission (SPE) and the contents of specific active compounds of roots and flowers buds of several fresh Chinese herbal medicines (natural medicines) with different growth ages and varieties. The results revealed that the contents of specific active compounds from same species herbs with different growth ages and varieties were significantly different, and this difference could be reflected by their SPE. Because the contents of specific bioactive constituents in Chinese herbs are closely related to their quality and curative effect, the SPE measurement technique may contribute to the quality control of Chinese herbal medicine in the future.

AbstractBackgroundUltra-weak photon emission (UPE), or biophoton emission, is a phenomenon observed in various living organisms, including plants. In this study, we analyzed the UPE from ripening strawberry fruits, to elucidate its source and association with cellular energy.MethodsFreshly harvested and stored strawberry fruits were measured for levels of UPE and energy molecules adenosine triphosphate (ATP), adenosine monophosphate (AMP) and adenosine diphosphate (ADP). The associations between them were calculated.ResultsIn ripening fruit, a decrease in UPE positively correlated with declining levels of ATP, AMP, and energy charge. In harvested fruits, levels of UPE, ATP, and energy charge declined, but ADP and AMP increased.ConclusionChanges in UPE levels synchronized with changes in ATP and energy charge, which reflect cellular energy levels. Thus, cellular energy may be related to UPE, and may be an energy source for UPE.

Certain sewage effluents have been found (Allen, Blezard, and Wheatland, 1946) to become highly toxic when treated with doses of chlorine much smaller than are required to give residual chlorine detectable by the ortho-tolidine test. Evidence from laboratory tests suggested that this toxicity was mainly due to a compound formed by interaction of the chlorine with small quantities of thiocyanate derived initially from gas liquor admitted to the sewage and surviving treatment at the sewage works. Key & Etheridge (1934) has shown that oxidation of the thiocyanate in a percolating filter or an activated-sludge plant, depends on the establishment of the necessary bacterial flora, and that a sudden increase in the concentration of thiocyanate in the sewage may result in a proportion of it being discharged in the effluent. Admission of gas liquor to sewage is common practice, and chlorination of such effluents would have serious effects on the living organisms, including fish, in surface waters to which they were discharged. Further work has revealed the nature of the compound responsible for toxicity, and has established the relation between toxicity and concentration of the substance in solution. An experimental study has been made of conditions affecting its formation during chlorination and of means of removing it from solution.

AbstractOne of the peculiar aspects of living systems is the production and conservation of energy. This aspect is provided by specialized organelles, such as the mitochondria and chloroplasts, in developed living organisms. In primordial systems lacking specialized enzymatic complexes the energy supply was probably bound to the generation and maintenance of an asymmetric distribution of charged molecules in compartmentalized systems. On the basis of experimental evidence, we suggest that lipophilic quinones were involved in the generation of this asymmetrical distribution of charges through vectorial redox reactions across lipid membranes.

Illumination Mode

The tilted beam illumination method is used to improve the resolution comparing with the axial illumination mode. Using this advantage, a restoration method of several tilted beam images covering the full azimuthal range was proposed by Saxton, and experimentally examined. To make this technique more reliable it seems that some practical problems still remain. In this report the restoration was attempted and the problems were considered. In our study, four problems were pointed out for the experiment of the restoration. (1) Accurate beam tilt adjustment to fit the incident beam to the coma-free axis for the symmetrical beam tilting over the full azimuthal range. (2) Accurate measurements of the optical parameters which are necessary to design the restoration filter. Even if the spherical aberration coefficient Cs is known with accuracy and the axial astigmatism is sufficiently compensated, at least the defocus value must be measured. (3) Accurate alignment of the tilt-azimuth series images.
