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.

Background: Chronic post-herpetic neuralgia (CPHN) is a symptomatic condition that afflicts adults and elderly individuals. The chronicity of this symptomatology can be conditioned by the epigenetic modifications induced by the virus on the processes of neurotransmission and sensitivity to pain. The aim of this study is to investigate whether manipulating endogenous bioelectrical activity (EBA), responsible for neurotransmission processes and contributing to the induction of epigenetic modifications, can alleviate pain symptoms., Methods: This manipulation was carried out with the antalgic neuromodulation (ANM) treatment of radioelectric asymmetric conveyer (REAC) technology. Pain assessment before and after treatment was performed using a numerical analog scale (NAS) and a simple descriptive scale (SDS)., Results: The results of the analysis showed an over four-point decrease in NAS scale score and over one point decrease in SDS scale score, with a statistical significance for both tests of p < 0.005., Conclusions: The results obtained in this study demonstrate how REAC ANM manipulation of EBA can lead to improvement in epigenetically conditioned symptoms such as CPHN. These results should prompt further research to expand knowledge and ensure optimized therapeutic outcomes.

About 30 percent of patients diagnosed with myelodysplastic syndromes (MDS) progress to acute myeloid leukemia (AML). The senescence of bone marrow?derived mesenchymal stem cells (BMSCs) seems to be one of the determining factors in inducing this drift. Research is continuously looking for new methodologies and technologies that can use bioelectric signals to act on senescence and cell differentiation towards the phenotype of interest. The Radio Electric Asymmetric Conveyer (REAC) technology, aimed at reorganizing the endogenous bioelectric activity, has already shown to be able to determine direct cell reprogramming effects and counteract the senescence mechanisms in stem cells. Aim of the present study was to prove if the anti-senescence results previously obtained in different kind of stem cells with the REAC Tissue optimization - regenerative (TO-RGN) treatment, could also be observed in BMSCs, evaluating cell viability, telomerase activity, p19ARF, P21, P53, and hTERT gene expression. The results show that the REAC TO-RGN treatment may be a useful tool to counteract the BMSCs senescence which can be the basis of AML drift. Nevertheless, further clinical studies on humans are needed to confirm this hypothesis.

Vaginal infections affect millions of women annually worldwide. Therapeutic options are limited, moreover drug-resistance increases the need to find novel antimicrobials for health promotion. Recently phytochemicals were re-discovered for medical treatment. Myrtle ( Myrtus communis L.) plant extracts showed in vitro antioxidant, antiseptic and anti-inflammatory properties thanks to their bioactive compounds. The aim of the present study was to create novel nanodevices to deliver three natural extracts from leaves, seeds and fruit of myrtle, in vaginal milieu. We explored their effect on human cells ( HeLa , Human Foreskin Fibroblast-1 line, and stem cells isolated from skin), resident microflora ( Lactobacillus acidophilus ) and on several vaginal pathogens ( Trichomonas vaginalis , Escherichia coli , Staphylococcus aureus , Candida albicans , Candida kefyr , Candida glabrata , Candida parapsilosis , Candida krusei ). Polycaprolactone-Gelatin nanofibers encapsulated with leaves extract and soaked with seed extracts exhibited a different capability in regard to counteracting microbial proliferation. Moreover, these nanodevices do not affect human cells and resident microflora viability. Results reveal that some of the tested nanofibers are interesting candidates for future vaginal infection treatments.

Human hematopoietic stem/progenitor cells (HSPCs) are pluripotent cells that gradually lose their self-renewal and regenerative potential, to give rise to mature cells of the hematopoietic system by differentiation. HSPC infusion is used to restore hematopoietic function in patients with a variety of onco-hematologic and immune-mediated disorders. The functionality of these cells is therefore of great importance to ensure the homeostasis of the hematopoietic system. Melatonin plays an important role as immunomodulatory and oncostatic hormone. In the present manuscript, we aimed at evaluating the activity of melatonin in modulating HSPC senescence, in the attempt to improve their hemopoietic regenerative potential. We exposed HSPCs to melatonin, in different conditions, and then analyzed the expression of genes regulating cell cycle and cell senescence. Moreover, we assessed cell senescence by β-galactosidase and telomerase activity. Our results showed the ability of melatonin to counteract HSPC senescence, thus paving the way for enhanced efficiency in their clinical application., (Copyright © 2022 The Authors.

Objective: Physical traumas can lead to unconscious neuropsychical alterations, which can compromise rehabilitation result and functional recovery. Aim of this interventional study is to verify if neurobiological Radio Electric Asymmetric Conveyer (REAC) treatments Neuro Postural Optimization (NPO) and Tissue Optimization (TO) are able respectively to improve neuro psychomotor strategies and facilitate recovery process in medial collateral ligaments (MCL) lesions of the knee., Patients and Methods: 45 healthy subjects, 32 males and 13 females, with knee MCL lesion, diagnosed with MRI or ultrasound. Within 4 days after the trauma, subjects were clinically evaluated (T0), both through medical and subjective assessments. Clinical evaluation was repeated after the REAC NPO treatment (T1) and at the end of 18 REAC TO treatments (T2) and at the 30 days follow-up (T3)., Results: In comparison with the results commonly found in clinical practice, all REAC treated patients recovered much faster. They reported functional recovery, pain relief and joint stability, regardless of the severity of the lesion., Conclusion: The combined use of REAC NPO and TO can envisage a new rehabilitative approach, which aims not only at recovering the outcomes of the physical trauma, but also at improving the neuropsychical state that can condition the rehabilitation result., (© 2020 The Author(s).)
