Background The purpose of this study was to assess the efficacy of specific neuromodulation treatments performed with radio electric asymmetric conveyer (REAC) technology in the treatment of the symptomatic triad depression, anxiety, and stress by the use of a specific psychometric test such as the Depression Anxiety Stress Scale-42 items (DASS-42) version, which assesses simultaneously the severity of expression of this triad. Patients and methods The design of this study was planned to compare two populations that performed DASS-42 test twice within a similar period of time. The first population performed the first DASS test before the treatment and the second test about 3 months later, at the end of two specific REAC neuromodulation treatments, neuropostural optimization (NPO) and neuropsychophysical optimization (NPPO), that have previously shown an efficacy in the treatment of depression, anxiety and stress. The second population (untreated), used as the randomized control group, consisted of a similar group by gender and age, who performed the DASS-42 test in an online platform twice, with an interval of about 3 months between the first and second tests, similar to the interval between the two tests in the treated group. Results The comparison between the treated group and the control group points out the REAC treatment efficacy in improving the quality of life. At the second DASS-42 test, self-administered about 3 months after the treatments, treated patients were positioned on average values of much milder severity in all the three clusters, depression, anxiety, and stress, while in untreated patients there was no significant difference between the mean values of the first and second DASS tests. Conclusion The results obtained in this study, evaluated with the DASS-42 test, confirm that REAC-NPO and REAC-NPPO neuromodulation treatments can be useful tools for the clinical treatment of depression, anxiety, and stress, as already proven by previous results evaluated with different psychometric tests.

Recent evidence suggests that ageing-related diseases could result in an accelerated loss of self-renewal capability of adult stem cells, normally involved in replacing damaged cellular elements. In previous works, we highlighted that a specific treatment, named tissue optimization-regenerative (TO-RGN), of radio-electric asymmetric conveyer (REAC) technology, influenced gene expression profiles controlling stem cell differentiation and pluripotency of human skin-derived fibroblasts in vitro. The purpose of the present work was to verify whether TO-RGN may also be effective in counteracting the expression of the senescence marker beta-galactosidase and of senescence-associated gene expression patterning, engaged during prolonged culture of human adipose-derived stem cells (hADSCs). Following TO-RGN exposure, we observed a significant downregulation in beta-galactosidase staining and in the expression of the senescence mediator genes p16INK4, ARF, p53, and p21CIP1. Moreover, differently formed untreated cells, TO-RGN-exposed hADSCs maintained their typical fibroblast-like morphology and exhibited a multilineage potential even at late passages, as shown by the remarkable preservation of commitment to osteogenic, adipogenic, chondrogenic, and vasculogenic fates, both at morphologic and gene expression levels. In conclusion, our study highlights a positive effect of TO-RGN in counteracting degenerative senescence processes in vitro.

BackgroundBeta-galactosidase is the most widely used biomarker for highlighting the processes of cellular aging, including neurodegeneration. On this basis, we decided to test in vitro whether a set of rescuing/reparative events previously observed by us in subjects treated with radioelectric asymmetric conveyor (REAC) technology may also involve antagonism of a marker of aging-related degenerative processes, as assessed by a reduction in beta-galactosidase at the cellular level.MethodsHuman adipose-derived stem cells were cultured at different passages, ranging from 5 to 20, with or without REAC exposure for 12 hours. The cells were then processed for biochemical beta-galactosidase staining and morphological microscopy analysis.ResultsWe observed a significant reduction in expression of senescence associated-beta-galactosidase, and a persistence of fibroblast-like morphology typical of human adipose-derived stem cells, even at late passages.ConclusionOur results indicate the ability of REAC technology to counteract in vitro senescence of human adipose-derived stem cells, and prompt the hypothesis that such technology may be exploited to antagonize in vivo senescence of tissue-resident or transplanted stem cells playing an important role in clinical treatment of age-related processes.
