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.

It has been found that nutrition does not provide the necessary quantities of some important trace elements, including iron and zinc. Iron is an essential element for all living organisms. It has a key role in the transport of oxygen and as a cofactor in many enzymes. Zinc is a component of more than 200 enzymes involved in the synthesis of proteins and DNA and is needed for the metabolism of growth factors. Enriching bread with mineral substances is a very good approach to overcoming the deficit and achieving adequate levels of intake. Different sources are used for this purpose, but there has been a growing interest in seaweed in recent years. The purpose of this study is to evaluate the effect of 2 and 4% Spirulina powder supplement on the iron and zinc content of bread made from wheat flour type 500. To determine the iron and zinc content, a highly sensitive ICP-AES method is used. Enrichment with 2% and 4% Spirulina plantesis has been found to increase the amount of zinc in wheat bread respectively to 6.36 ± 0.64 mg/kg and 6.77 ± 0.68 mg/kg, whereas its content in the control sample is 5.99 ± 0.49 mg/kg. The amount of iron in the enriched samples reached 15.9 ± 1.59 mg/kg with the addition of 2% Spirulina plantensis and 24.7 ± 2.48 mg/kg with the addition of 4%, while in the control sample of bread was 7.22 ± 0.58 mg/kg. Practical applicationsThe addition of Spirulina platensis algae to wheat bread increases its biological value and helps to achieve iron and zinc content amounts close to the recommended daily intake levels.

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.

Aptamers are short single-stranded DNA or RNA oligonucleotide ligand molecules with a unique three-dimensional shape, capable of binding to a defined molecular target with high affinity and specificity. Since their discovery, aptamers have been developed for various applications, including molecular imaging, particularly nuclear imaging that holds the highest potential for the clinical translation of aptamer-based molecular imaging probes. Their easy laboratory production without any batch-to-batch variations, their high stability, their small size with no immunogenicity and toxicity, and their flexibility to incorporate various functionalities without compromising the target binding affinity and specificity make aptamers an attractive class of targeted-imaging agents. Aptamer technology has been utilized in nuclear medicine imaging techniques, such as single photon emission computed tomography (SPECT) and positron emission tomography (PET), as highly sensitive and accurate biomedical imaging modalities towards clinical diagnostic applications. However, for aptamer-targeted PET and SPECT imaging, conjugation of appropriate radionuclides to aptamers is crucial. This review summarizes various strategies to link the radionuclides to chemically modified aptamers to accomplish aptamer-targeted PET and SPECT imaging.
